[0035] The driving mechanism 5 includes a motor 2 51 fixed on the top of the fixed plate 211 , and a gear 52 is fixed to the top of the output shaft of the motor 2 51 . One side of the gear 52 is meshed with the one-way gear 2 35 , and the other side of the gear 52 is meshed with the one-way gear 1 213 .

[0036] A controller is fixed on one side of the supporting plate 28 , and the controller is electrically connected to the motor 1 14 , the motor 2 51 and the push rod motor 414 , respectively.

[0037] Working principle: The material passes between the glue roller 16 and the arc scraper 49, and then is connected to the winding device. The controller starts the motor 14 to drive the glue roller 13 to rotate and stick the glue to the surface, so that the glue contacts the glue roller 16. The controller starts the motor 2 51 to drive the gear 52 to rotate forward. The forward rotation of the gear 52 satisfies the direction of the rotation of the one-way gear 213 to drive the shaft 212 to rotate. The shaft 212 rotates through the slider 1 215, the bevel gear 4 216 to drive the bevel gear 3 220, the shaft 1 218, the bevel gear 2 219, the bevel gear 1 25 and the double-section reciprocating threaded rod 1 22 connected to the bevel gear 1 25 to rotate. The double-section reciprocating threaded rod 1 22 rotates through the pulley 1 23 and the belt 1 24 to drive another The double-stage reciprocating threaded rod 22 rotates, and the rotation of the double-stage reciprocating threaded rod 22 causes the two moving blocks 26 to drive the pressing rollers 27 to move away from each other. The farther the pressing rollers 27 are, the larger the contact area between the material and the glue coating roller 16 when the material is pressed. The larger the contact area, the more uniform the amount of glue transferred from the glue coating roller 16 to the material surface, avoiding the situation where glue is missing at a certain position on the material surface. The adjustment of the contact area is determined by the adsorption force of the transfer between the glue and the material, so it is necessary to control the contact area according to the adsorption force of the transfer. After the moving block 26 moves to the specified position, it stops moving, and then the motor 2 51 is started to drive the gear 52 to reverse. The reversal of the gear 52 satisfies the one-way gear 23. 5 drives the reciprocating screw 32 to rotate, and the rotation of the reciprocating screw 32 drives another reciprocating screw 32 to rotate through the pulley 2 33 and the belt 2 34, so that the Z-type moving frame 36 drives the structure box 21 and the pressure roller 27 and other structures to move downward. When moving downward, the bevel gear 4 216 and the slider 1 215 follow the downward movement by their own gravity, so that the bevel gear 4 216 is always meshed with the bevel gear 3 220. During the downward movement of the pressure roller 27, the arc scraper 2 412 of the winding anti-sticking mechanism 4 is in a retracted state, so it will not affect the downward movement of the pressure roller 27. When the pressure roller 27 moves downward, it contacts the top of the material and presses the material downward. If the moving distance of the pressure roller 27 is less than the straight line of the glue coating roller 16 When the nip roller 27 moves down to a specified height, it will cooperate with the top of the glue roller 16 to make the material close to the glue roller 16. If the distance moved by the nip roller 27 is greater than the diameter of the glue roller 16, the nip roller 27 will move down to be lower than the center position of the glue roller 16, and then the motor 2 51 will be started to drive the gear 52 to rotate forward, so that the double-section reciprocating threaded rod 1 22 rotates and drives the two nip rollers 27 to approach each other. When they are close, the material is squeezed to make it close to the glue roller 16, and then the nip roller 27 cooperates with the bottom of the glue roller 16 to make the material close to the glue roller 16. The greater the distance the nip roller 27 moves down, the larger the area of ​​the glue roller 16 wrapped by the material when it is close, the more uniform the glue transfer is, and the better the effect is. The pressure roller 27 can adjust the distance that the double-section reciprocating threaded rod 22 drives the pressure roller 27 to move according to the material of the material, and apply different pressures to the material, thereby ensuring the effect of glue transfer.

[0038] According to the width of the material, the second sliding block 417 drives the scraper 418 to move, adjust the scraping position, and scrape off the excess glue on the adhesive roller 13 to prevent the excess glue from sticking to the back of the material; The winding device pulls the material to drive the pressing roller 27 and the glue coating roller 16 to rotate. When the glue coating roller 16 rotates, the glue on the glue coating roller 13 is evenly adhered to the surface, and then the glue is brought into contact with the material during rotation, and then the long area of ​​contact is used to achieve uniform glue coating; The glue coating roller 16 rotates through the pulley three 41, the belt three 44 and the pulley four 43 to drive the double-section reciprocating threaded rod two 42 to rotate, so that the moving block two 46 moves back and forth on the reciprocating thread, and the moving block two 46 moves to drive the slide plate 47, the counterweight block 48 and the arc scraper one 49 and other structures to move. When moving, the arc scraper one 49 scrapes the glue on the back edge of the material to the surface of the glue coating roller 16 on both sides to avoid the situation where the residual glue on the back makes the materials stick together and difficult to separate after winding. The counterweight block 48 presses the slide plate 47 downward to make the arc scraper one 49 and the arc scraper two 412 always in contact with the back of the material. Before scraping, the push rod motor 414 is started to push the connecting plate 415, so that the arc scraper two 412 drives the slider three 411 to move, and the length of the arc scraper one 49 is extended to be the same as the length of the material close to the glue coating roller 16, so that the arc scraper one 49 increases the scraping area.
