1. Preparation
1.1 Production of glue template
According to the size of the paper film window, choose a Teflon offset plate with a thickness of 0.5mm from the width of 300mm-720mm, align one edge of the paper product to be stuck with the side of the offset plate, and then use a mark The pen draws the window outline on the offset plate along the window, removes the paper product, and draws a 5mm wide glue position line along the window outline on the offset plate with a marker pen. Use 2mm thick double-sided adhesive tape to stick the rubber strip on one side, and stick the rubber strip to the glue position on the other side. At the same time, in order to make the rubber strip and the rubber plate adhere firmly, you can use adhesive paper to stick around the bottom of the rubber strip layer. The thickness of the glue template is about 10mm after assembly.
Then insert the hook strip at one end of the offset plate into the groove of the plate roller, and stick the other end to the plate roller with adhesive paper to tightly wrap the offset plate on the outer surface of the plate cylinder.
1.2 Installation of cutting knife
Manually turn the cutter roller to the top, put the upper blade into the cutter groove of the cutter roller, make the lower end of the blade fully contact with the bottom of the cutter groove, and tighten the 18 M6 × 15 tightly Set screws.
When installing the lower blade, insert the blade into the blade holder through the through hole of the fuselage, use a wrench to slightly tighten the middle screw and the two screws at both ends, manually turn the cutter roller to rotate, wait for the upper blade edge to turn to the lower and lower blades The knife edge is aligned to stop turning, adjust 19 M8 × 110 screws one by one to make the gap between the upper blade and the lower blade between 0.03-0.05mm, tighten 18 M10 × 95 screws, make the pressure plate press the lower knife, then tighten M8 nut.
The cutting edges on each side of each cutting blade can be used alternately. When the cutting edge of the blade becomes dull, it is necessary to grind the two surfaces to continue to use. Generally, the new blades are installed in the cutter roller, and the lower blade can be adjusted by M8 × 110 screw to adjust the height of the blade extension to control the gap between it and the upper blade.
The clearance adjustment of the upper and lower blades must be very careful and careful, otherwise it will cause damage and faster wear.
1.3 Preparation of film and glue
Most of the films attached to the window are polypropylene (PP) and polyethylene (PE). The width of the film roll is generally about 15-20mm wider than the window. The whole roll of film opened according to the width of the window on the paper product is installed on the material rack device at the rear of the host. The length of the film is generally 30mm longer than the length of the window.
Different membranes should be equipped with corresponding glue. Generally, water-soluble white glue is used. The glue should comply with environmental protection standards, and it does not contain toxic substances and substances that will not harm the ozone layer. The premise of the equipment is based on the glue sticking film.
[next] 2. Adjustment and operation
2.1 Paper feed
After finishing the paper products that need to be filmed after die-cutting and creasing, they are stacked on the paper feeding table with the feet inclined, and the bottom sheet of paper is pulled out and separated from the paper pile by the paper feeding belt during rotation. With the rotation of the paper feeding belt, the paper products pass between the paper feeding belt and the pressing roller and enter the paper feeding device.
2.2 Conveyance of paper products
After the paper product enters the paper conveying device through the paper feed belt, the paper product is conveyed forward by the paper pusher on the chain and pushed forward at the rear end of the paper product. Onto the vacuum conveyor belt of the gluing device.
Due to the changes in the specifications of the processed paper products and the different positions of the windows, it is necessary to adjust the paper conveying position as necessary.
Paper feed position adjustment Select the paper feed belt position according to the shape of the processed paper product, loosen the tension roller of the paper feed belt, move the paper feed belt to the desired position and fix it.
Loosen the star handle on the roller frame, move the paper pressure roller on the roller frame to align the conveying wheel with the paper pressure roller, and tighten the star handle.
Adjusting the paper conveying position. When the laminated paper products use two paper pushing gauges on the conveying chain to push the paper products at the same time, or when two paper pushing gauges are required to be in sequence, you can loosen the screws on the sprocket and pull the chain by hand. When the sprocket in the empty sleeve is idling on the driving shaft, it can drive the paper stopper on the chain to move forward and backward, and adjust the stopper to the appropriate position that will be pushed to the jammed paper, and then lock the screw.
2.3 Adjustment of gluing device
Adjustment of glue amount
Loosen the two star-shaped handle screws and turn the two handles on the left and right sides of the small wall board at the same time to adjust the gap between the rubber transfer roller and the glue roller. The handle rotates upward and the gap between the two rubber rollers is small, so the amount of glue applied is small. On the contrary, the handle turns downward, the amount of glue is large. After adjusting to the appropriate amount of glue, tighten the star handle screw.
In order to avoid the condensation of the glue on the glue roller and the glue transfer roller during shutdown, the glue roller is equipped with a motor. When the host machine is stopped, the motor starts the glue roller and the glue transfer roller to continue to rotate.
2.4 Glue
The paper products are transported by eleven flat belts with holes in the gluing and filming stations. The suction pump generates negative pressure to attract the jammed paper on the moving conveyor belt through the small holes on the flat belt, so that the jammed paper can be kept in the correct position and enter the glue part. The glue roller transfers the glue to the rubber transfer roller, which then applies the glue to the rubber strip of the plate. When paper products are transported to the plate roller to apply glue, the two electromagnetic Suction iron drives the lever to force the suction paper platen to rise, and the glue on the rubber strip is correctly applied to the window part of the paper product through the rotation of the roller.
Gap adjustment between rubber transfer roller and plate roller
Pull the handle down, and then turn the two-star handle screw on the top of the small wallboard to adjust the gap between the rubber transfer roller and the plate roller. Turn the star handle screw counterclockwise to reduce the gap between the transfer roller and the plate roller, and the amount of glue increases; otherwise, the gap increases and the amount of glue decreases. If the plate roller does not need to be glued, pull the handle back up to stop glueing.
Gap adjustment between plate roller and flat conveyor belt
Loosen the two handles on the outside of the operation surface wallboard and the inside of the transmission surface wallboard, and turn the two spherical handles respectively to move the plate roller up and down, thereby changing the gap between the plate roller and the conveying flat belt to adapt to different thicknesses of paper Product, and then lock the two handles.
If the gap between the plate roller and the conveying flat belt is too small, it will cause the glue on the rubber strip of the rubber plate to be transferred to the conveying flat belt through the roller rotation and affect the working state of the conveying flat belt when no paper is conveyed.
Air volume adjustment and control of the paper-feeding table
The paper products are pushed down by the chain conveyor block to the vacuum flat belt conveying table. There are eleven circular paper conveyor belts on the table. When the suction motor starts, the suction air sucks the paper products through the small holes on the paper conveyor belt. The conveyor belt runs together, and there are ten adjustment screws on the paper table to adjust the suction volume. Among them, nine adjustment screws are arranged in a line. Turning the screw clockwise can reduce or close the suction volume, otherwise, press counterclockwise Rotation in the direction increases the amount of suction. There is an adjustment screw which rotates counterclockwise to reduce or close the suction volume.
When the width of the jammed paper is smaller than the widths of the multiple adjustment screws on the paper table, you can close the unnecessary air holes by turning the adjustment screws to increase the effective wind force.
Adjustment of the circumferential position of the plate roller
Install the offset plate on the plate roller, use the ink of the printing platform to coat the rubber strip, jog the machine, the paper product is pushed to the glue position through the chain push paper stop gauge, and the ink is printed on the plate roller as the plate roller rotates According to the difference of the relative position of the window to be filmed on the paper product and the plate, by loosening the M8 set screw on the plate roller inside the operation surface wall panel, the plate roller can be rotated for circumferential position The adjustment is such that the rubber strip on the rubber plate is aligned with the front and back positions of the film window, and then the M8 set screw is tightened.
If there is a difference between the left and right relative positions of the ink printed on the window of the jammed paper and the window to be stuck on the jammed paper, the paper positioning positioning side gauge and the paper feeding positioning block can be adjusted appropriately, and the plate roller can also be finely adjusted left and right. .
[next] 2.5 film
The film sticking is carried out in four steps: film feeding, film cutting, film conveying and film sticking. Install the whole roll of film opened according to the width of the window on the jammed paper to the material rack device at the rear of the host. The length of the film is generally 30mm longer than the length of the window, and the width of the film roll is about 25-30mm wider than the window. According to the length of the window needed for the film on the paper product, the diaphragm is continuously output by the stepless governor at a preset speed, and the film roll is continuously output by a pair of film feeding rubber and power rollers, and sent to the film cutting roller And cut through the knife edge, while cutting, the film is absorbed and transferred by the film conveying roller. When it is accurately opposed to the window of the paper product, the film roll changes from suction to air due to the action of the air valve After blowing, the film and cardboard are rolled and the film is sent out.
Adjusting the length of the cut film
The film cutting length is generally 30mm longer than the window length, and the film roll width is about 30mm wider than the window. The cutting length of the diaphragm is within the range given by the machine, and can be adjusted according to the size of the jammed window. On the drive side of the machine, there is a stepless speed governor with digital scale adjustment. A sprocket coaxial with the gear on the cutter roll drives the sprocket on the input shaft of the stepless speed governor. After deceleration, the output chain The wheel output drives the film-feeding power roller sprocket to keep the power roller and the cutter roller at the set rotation speed relationship, so that the cut film is a certain length, and it is adjusted to the required length by adjusting the hand wheel. The cutter will cut the long film stably.
It is strictly forbidden to rotate the adjusting handwheel in the stop state, otherwise it may cause damage to the continuously variable transmission.
Installation and adjustment of diaphragm width
Install the diaphragm roll on the feeder shaft, push the handle on the wallboard counterclockwise to loosen the rubber roller, pass the diaphragm through the lower blade, and then release the handle. The diaphragm is transported out as the machine rotates. When the conveyed film is pasted on the paper product window and there is a deviation in the width direction, the relative position of the film roll on the axis of the feed frame is moved by loosening the three M6 screws at both ends of the film roll to make the film pair For the quasi-jam window, loosen the M10 nut and knurled nut, and rotate the adjustment hand wheel to realize the fine adjustment of the position of the jam window by the roll film. After the adjustment is completed, the screw and nut are locked. If the diaphragm is too wide, use a cutter to cut the diaphragm to the desired width. If the diaphragm needs to be indented, the heating device can be adjusted to indent the diaphragm.
Control and adjustment of the air volume of the film-cutting roller and film-sticking roller
There are three handles on the inhalation air distribution block and the inhalation air distribution block respectively for the air volume adjustment switch. When the spool at the handle is in the horizontal state, it is closed. The spool at the handle is in the vertical state for maximum air volume.
Adjustment of the position of the paper window on the diaphragm and conveying flat belt
When the paper product is transported to the filming station, if the film and the film window on the paper product are misaligned back and forth, stop the machine, press and hold the adjustment button of the middle button board, and then release the handle outside the wall panel of the operation surface, and according to the film The position of the film and the paper product is turned counterclockwise to adjust the handwheel, so that the paper product reaches the film position in advance; on the contrary, the position where the film is attached to the paper product window is late, and the handwheel is adjusted clockwise to adjust the handwheel so that the paper product will Slowly reach the film position. After the position of the film is correct, lock the handle and apply the film normally after applying the glue.
2.6 Adjustment of paper output collection position
After the window film is finished, the paper product is sent out by the conveying flat belt and falls on the flat belt of the paper collection table. Because the crank connecting rod mechanism makes the paper conveying flat belt intermittently move in one direction, the paper product is completed under the weight of the nylon wheel Stacking and collection of paper products.
Keep the machine in operation, and rotate the adjusting screw located at the rear of the take-up table to drive the belt passive roller to move forward and backward, so that the flat belt is properly tightened and does not run off during transmission.
Loosen the locking handle and turn the adjusting handle counterclockwise to keep the gap between the conveying flat belt and the diaphragm conveying roller at a sheet thickness.
Move the connecting plate in the axial direction so that the two nylon rollers are on the glue area on both sides of the window.
Rotate the adjustment screw at the end of the wallboard to adjust the height and front and rear positions of the delivery stand. Rotate the adjustment screw clockwise to increase the delivery stand and move closer to the conveyor flat belt. Otherwise, the delivery stand is lowered and away from the conveyor The flat belt and the take-up table are adjusted to keep the rear sheet of paper correctly falling to the middle of the previous sheet of paper, without slanting the already attached diaphragm on the front sheet of paper.
