Description

Technical Field

[0002] As a key material in industries such as electronics, optics, and packaging, the lamination process of textured protective film directly determines the precision of the texture on the product surface, the adhesion of the film layer, and the overall durability. The lamination structure is the core device for realizing texture forming and film material lamination. It mainly consists of components such as textured rollers, pressure rollers, temperature control systems, and conveying mechanisms. The film material is bonded to the substrate through the pressure between the rollers, and the preset texture pattern is formed by replicating the texture of the textured rollers. This structure requires precise control of the coordinated matching of pressure, temperature, and conveying speed to ensure the uniformity of the texture and the absence of air bubbles in the film layer, so as to meet the performance requirements of protective film in different scenarios.

[0003] However, the existing pressing structure does not make it easy to restrict the position of the protective film during use, which can cause the protective film to shift during the pressing process, affecting the subsequent extrusion work and thus reducing the quality of the protective film.

[0013] 1. By setting up a correction section, during use, the elastic element and the limiting roller work together to limit the position of the protective film. When the protective film deviates, the elastic element generates force to reset it. The adjustment component drives the relevant parts to move with the help of the rotating part, so that the two centering components move closer or further apart, thereby adapting to protective films of different widths. It can effectively limit the position of the protective film during the pressing process, avoid the position of the protective film from deviating, ensure the smooth progress of subsequent extrusion work, and thus improve the quality of the protective film. At the same time, it can be adapted to a variety of protective films of different widths, enhancing the versatility of the pressing structure.

[0014] 2. By setting up an opening and closing part, during disassembly and assembly, the transmission component is driven by external operation to move, which in turn drives the slider to move the limit roller to achieve opening and closing. The locking component, through the cooperation of the snap-fit ​​part and the slot, locks and fixes the rotating component after the limit roller is adjusted to the appropriate position, preventing it from rotating on its own and affecting the limiting effect. This can realize the opening and closing operation of the limit roller, ensuring the stability of the limit when limiting and fixing the protective film. When it is necessary to replace the protective film, the limit can be easily released, making the disassembly and assembly process of the protective film more efficient and providing convenience for the continuous operation of the film pressing.

[0028] It should be noted that the control of motor 104 and motor 224 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0029] A specific application of this embodiment is as follows: In use, the protective film can be passed between several limiting rollers 214 and between the mesh roller 103 and the receiving roller 102. At this time, the protective film can be pulled by an external traction device. Then, the handle 312 can be rotated to drive the rotating shaft 311 to rotate. When the rotating shaft 311 rotates, it will drive the rotating block 313 to rotate, so that it drives the two sliders 212 to slide in the connecting block 211 through the hinge rod 314, thereby driving the two limiting rollers 214 to restrict the protective film. When the slider 212 slides, the spring 213 will stretch and generate elastic force. At the same time as the rotating shaft 311 rotates, it can also drive the connecting block 322 to rotate in the connecting block 321. When the connecting block 322 rotates, the slot 323 will squeeze the block 324, so that it slides in the connecting block 322. At this time, the spring 325 is compressed and generates elastic force. When the block 324 slides completely into the connecting block 322, the connecting block 322... 2 will rotate normally, and then motor 104 can be started, so that its output shaft drives the grid roller 103 to press the protective film. The protective film can also be pulled by an external traction device. When the protective film deviates, it will squeeze the baffle 215, so that the sleeve 1 216 will slide in the sleeve 217. At this time, the spring 218 is compressed and generates elastic force. Under the action of this elastic force, the protective film will be pushed back by the baffle 215, thereby ensuring the stability of the protective film. When the protective film needs to be replaced, the locking block 324 can be pulled to slide out of the locking groove 323, and the handle 312 can be rotated in the opposite direction. With the assistance of the spring 213, the two limiting rollers 214 will be separated, so that the film can be removed. When it is necessary to roll the protective film of various widths, motor 224 can be started, so that its output shaft drives the two connecting blocks 222 to move closer or further away from each other through the bidirectional threaded rod 223, and drives the two centering components 21 to move closer or further away from each other, thereby completing the adjustment.
