Description

Technical Field

[0001] This invention relates to the field of breathable film technology, and more particularly to a breathable film bonding and pressing device. Background Technology

[0002] In modern industrial production, film lamination is widely used in the surface treatment of various types of sheets to provide protection, decoration, or special functions. Existing film lamination equipment mostly employs a simple roller pressing structure, coupled with manual or semi-automatic film unwinding and rewinding systems, to achieve initial bonding between the film and the substrate. This type of equipment typically has a relatively simple structure and basic functions, making it difficult to meet the requirements of high-quality, high-precision lamination.

[0003] The patent document with publication number CN115107268B discloses a breathable film bonding and pressing device and its implementation method, which belongs to the field of breathable film technology. In order to solve the problems that the film edge wrinkles or warps and leaks air due to the pulling force of the cutter, the edges of the workpiece are not evenly bonded to the film, and the cut film scraps are difficult to use and waste resources.

[0004] In the aforementioned designs and existing technologies, uneven tension, wrinkling, or misalignment of the film during transport can easily occur, affecting the bonding effect. Excessive tension can cause film deformation. The pressing stage relies heavily on operator experience to control pressure and movement speed, which can easily lead to uneven bonding, air bubbles, or edge lifting. There is a lack of effective real-time quality monitoring methods, and problems are often only discovered after bonding is completed, resulting in waste of materials and time. In addition, most equipment does not have automatic cutting and waste removal functions, and manual trimming is still required afterward, resulting in low production efficiency. Therefore, we propose a breathable film bonding and pressing device to solve this problem. Summary of the Invention

[0018] The beneficial effects of this invention are as follows:

[0019] 1. In this invention, a breathable film laminating and pressing device is described, which pulls out the film wound on the outside of the take-up roller, thus bypassing the left guide roller, tension roller, positioning roller and the right positioning roller, tension roller and guide roller, and then wraps around the outside of the take-up roller. Then, the take-up motor is started to drive the take-up roller to rotate counterclockwise to realize the take-up of the film. After the film is tightened, the two tension rollers move upward under the tension of the film, and drive the counterweight plate to move upward. The counterweight plate drives the second touch panel to contact the second touch switch. The second touch switch controls the start of the unwinding motor, which drives the unwinding roller to rotate counterclockwise to realize the unwinding of the film. Thus, the film can be transported through the cooperation of the unwinding roller and the take-up roller.

[0020] 2. In this invention, a breathable film laminating and pressing device is described. The sheet material to be laminated is placed on top of the lifting seat. A servo motor is then activated to rotate the active bevel gear, which in turn rotates the bidirectional screw through meshing with the driven bevel gear. The bidirectional screw, through threaded transmission with two clamping plates, brings the two clamping plates closer together, causing them to abut against both sides of the sheet material for clamping and fixing. Next, the controller stops the winding and unwinding motors, and then activates the second electric push rod to move the lifting seat upwards, causing the top of the sheet material to adhere to the film. The lifting seat then continues to move the sheet material upwards, pulling the film upwards and causing the two tension rollers to move upwards. During this process, the tension force on the film remains constant. When the first touch panel contacts the first touch switch, the first touch switch controls the second... The electric push rod stops operating and controls the first electric push rod to start. The first electric push rod drives the lifting frame to move downward, thereby driving the flattening roller to move downward, so that the flattening roller presses against the top of the film. After the flattening roller contacts the film, it stops moving downward. The first electric push rod drives the lifting frame to continue moving downward, thereby compressing the connecting spring and the vertical spring. The pressure is monitored by the first pressure sensor. When the pressure value reaches the preset value, the controller controls the first electric push rod to stop feeding and controls the drive motor to start and drive the lead screw to rotate. The lead screw drives the moving plate to move back and forth left and right under the guidance of the crossbar through the thread engagement with the moving plate. The conductive moving frame of the moving plate and the flattening roller move back and forth left and right, so that the film and the board are tightly bonded. At the same time, the ring cutter can cut the front and rear edges of the film and the board to remove excess waste.

[0021] 3. In this invention, a breathable film laminating and pressing device is used. When air bubbles, dust, particles, or wrinkles appear between the film and the substrate, the flattening roller moves horizontally and vertically simultaneously. This vertical movement, via a connecting rod, drives the piston plate to move up and down. When the piston plate moves downwards, liquid from the storage tank enters the compression tank through the inlet pipe. When the piston plate moves upwards, liquid from the compression tank is directed into the sealing box. Backflow is prevented by a first and a second one-way valve. The more unevenness occurs, the more liquid is continuously fed into the sealing box, pushing the sealing plate to the right. The second pressure sensor is then compressed, and the pressure change of the second pressure sensor is used to determine the flatness of the film. When the sealing plate contacts the touch button, it indicates that the adhesion between the film and the board does not meet the requirements. The controller then controls the drive motor to stop running, and the problem is investigated. The sealing plate can be reset under the action of the transverse spring by opening the electric control valve, and the liquid in the sealing box can be returned to the storage tank. During operation, if the pressure on the film is too high, the counterweight plate will contact the control button, and the controller will control the drive motor to stop running to prevent the film from breaking.

[0022] 4. In this invention, when the pressure value detected by the first pressure sensor does not reach the preset value after the flattening roller has moved back and forth a preset number of times, the controller controls the cutting motor to start, drives the drive arm to rotate, and drives the rotating arm to rotate through the linkage rod, and drives the knife holder and cutting knife to perform circumferential motion, and cooperates with the support plate to cut the left and right edges of the film, thereby completing the film bonding and pressing. Then, the first electric push rod is controlled to drive the lifting seat to reset, and the unwinding motor and rewinding motor are started to realize the film conveying. Then, the servo motor is started to drive the clamping plate to move in the opposite direction to release the clamping, so as to facilitate the removal of the plate.

[0023] 5. The breathable film laminating and pressing device of this invention can realize automatic film conveying and tension control, effectively ensuring the flatness and stability of the film during the transmission process. The clamping and lifting mechanism can automatically clamp the board and control its lifting and positioning. With the help of the roller pressing mechanism, the film and board are tightly pressed together and the edges are automatically cut, improving the lamination accuracy and efficiency. The device is also equipped with a monitoring mechanism, which can detect the pressure change and lamination quality in real time during the pressing process. It can automatically identify and stop the machine in case of abnormality to ensure product quality. At the same time, it integrates a cutting function, which can automatically complete the edge trimming after pressing, further reducing manual intervention and improving the degree of production automation and product consistency. In addition, the device can simultaneously complete the cutting and separation of edge waste during the pressing process. The generated plastic waste is neat and uniform, which greatly facilitates subsequent recycling and is in line with the concept of green manufacturing. Attached Figure Description

An unwinding mechanism 1 and a winding mechanism 2 are respectively provided on the top two sides of the base 10. The unwinding mechanism 1 includes: an unwinding roller 103, an unwinding frame 101 and an unwinding motor 102. The unwinding roller 103 is rotatably installed in the unwinding frame 101. The unwinding motor 102 is fixedly installed on the front side of the unwinding frame 101. The front end of the unwinding roller 103 is fixedly installed on the output shaft of the unwinding motor 102.

[0057] The winding mechanism 2 includes a winding roller 203, a winding frame 201, and a winding motor 202. The winding roller 203 is rotatably mounted inside the winding frame 201. The winding motor 202 is fixedly mounted on the front side of the winding frame 201. The front end of the winding roller 203 is fixedly mounted on the output shaft of the winding motor 202. The unwinding frame 101 and the winding frame 201 are both fixedly mounted on the top of the base 10.

[0058] In this embodiment, during use, the film wound on the outside of the take-up roller 203 is pulled out, thus bypassing the left guide roller 403, tension roller 405, positioning roller 502 and the right positioning roller 502, tension roller 405, and guide roller 403, and then wound around the outside of the take-up roller 203. Then, the take-up motor 202 is started to drive the take-up roller 203 to rotate counterclockwise to achieve the take-up of the film. After the film is tightened, the two tension rollers 405 move upward under the tension of the film, and drive the counterweight plate 404 to move upward. The counterweight plate 404 drives the second touch panel 408 to contact the second touch switch 409. The second touch switch 409 controls the unwinding motor 102 to start, driving the unwinding roller 103 to rotate counterclockwise to achieve the unwinding of the film. Thus, the film can be transported through the cooperation of the unwinding roller 103 and the take-up roller 203.

[0059] By placing the sheet material to be laminated on top of the lifting seat 601, the servo motor 610 is started to drive the active bevel gear 609 to rotate, and through meshing with the driven bevel gear 608, it drives the bidirectional screw 607 to rotate. The bidirectional screw 607 drives the two clamping plates 605 to move closer together through threaded transmission with the two clamping plates 605, so that the two clamping plates 605 abut against the two sides of the sheet material to achieve clamping and fixation. Then, the controller 3 controls the winding motor 202 and the unwinding motor 102 to stop running, and then starts the second electric push rod 604 to drive the lifting seat 601 to move upward, so that the top of the sheet material is laminated with the film. Then, the lifting seat 601 drives the sheet material to continue to move upward, and pulls the film upward, driving the two tension rollers 405 to move upward. During this process, the tension force on the film remains unchanged. When the first touch panel 406 contacts the first touch switch 407, the first touch switch 407 controls the second electric push rod 604 to stop running and controls the first electric push rod 605 to stop running. When push rod 710 is activated, the first electric push rod 710 drives the lifting frame 701 to move downward, thereby driving the flattening roller 708 to move downward, so that the flattening roller 708 presses against the top of the film. After the flattening roller 708 contacts the film, it stops moving downward. The first electric push rod 710 drives the lifting frame 701 to continue moving downward, thereby compressing the connecting spring 716 and the vertical spring 904. The pressure is monitored by the first pressure sensor 902. When the pressure value reaches the preset value, the controller 3 controls the first electric push rod 710 to stop feeding and controls the drive motor 703 to start and drive the lead screw 704 to rotate. The lead screw 704 drives the moving plate 705 to move back and forth left and right under the guidance of the crossbar 702 through the threaded engagement with the moving plate 705. The conductive moving frame 706 and the flattening roller 708 of the moving plate 705 move back and forth left and right, so that the film and the board are tightly bonded. At the same time, the ring cutter 709 can cut the front and rear edges of the film and the board to remove excess waste.

[0060] When air bubbles, dust, particles, or wrinkles appear between the film and the substrate, the flattening roller 708 moves up and down while moving horizontally. This movement, via the connecting rod 812, drives the piston plate 811 to move up and down. When the piston plate 811 moves downwards, liquid in the storage tank 802 enters the compression tank 803 through the inlet pipe 805. When the piston plate 811 moves upwards, it guides liquid from the compression tank 803 into the sealing box 804. Backflow is prevented by the first one-way valve 806 and the second one-way valve 810. The more unevenness occurs, the more liquid is continuously fed into the sealing box 804, pushing the sealing plate 8041 to the right, thereby compressing the second pressure sensor 804. 3. The pressure change of the second pressure sensor 8043 is used to determine the flatness of the film. When the sealing plate 8041 contacts the touch button 8042, it indicates that the adhesion between the film and the plate does not meet the requirements. The controller 3 then controls the drive motor 703 to stop running, and then troubleshoots the problem. The sealing plate 8041 is reset under the action of the transverse spring 8045 by opening the electric control valve 808, and the liquid in the sealing box 804 flows back into the storage tank 802. During operation, when the pressure on the film is too high, the counterweight plate 404 contacts the control button 412, and the controller 3 controls the drive motor 703 to stop running to prevent the film from breaking.

[0061] When the pressure roller 708 reciprocates a preset number of times, if the pressure value detected by the first pressure sensor 902 does not reach the preset value, the controller 3 controls the cutting motor 510 to start, driving the drive arm 509 to rotate, and through the linkage rod 508, driving the rotating arm 505 to rotate, and driving the knife holder 506 and the cutting knife 507 to perform circumferential motion, and cooperate with the support plate 503 to cut the left and right edges of the film, thereby completing the film bonding and pressing. Then, the first electric push rod 710 is controlled to drive the lifting seat 601 to reset, and the unwinding motor 102 and the winding motor 202 are started to transport the film. Then, the servo motor 610 is started to drive the clamping plate 605 to move in the opposite direction to release the clamp, so as to facilitate the removal of the board.

[0062] It can realize automatic film feeding and tension control, effectively ensuring the flatness and stability of the film during the transmission process. The clamping and lifting mechanism 6 can automatically clamp the board and control its lifting and positioning. Together with the roller pressing mechanism 7, it can achieve tight pressing of film and board and automatic edge cutting, improving the bonding accuracy and efficiency. The device is also equipped with a monitoring mechanism 8, which can detect pressure changes and bonding quality in real time during the pressing process, automatically identify abnormalities and stop the machine to ensure product quality. At the same time, it integrates a cutting function, which can automatically complete edge trimming after pressing, further reducing manual intervention and improving the degree of production automation and product consistency.
