Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a fully automatic PP sheet laminating machine, comprising a machine body 1, a belt conveyor 2 fixedly connected to the inner side of the machine body 1, the belt conveyor 2 realizing the automatic transfer of PP sheets within the machine body 1 through the cyclic rotation of the belt, providing a conveying foundation for the subsequent laminating process, a film feeding mechanism 3 fixedly connected to the upper surface of the machine body 1, the film feeding mechanism 3 being responsible for conveying the film required for laminating to a designated position at a set speed and direction, preparing materials for the laminating operation, and an adjusting plate feeding mechanism 4 fixedly connected to the upper surface of the machine body 1 on the side near the film feeding mechanism 3. The adjustable feeding mechanism 4 can adjust the conveying speed and position of the PP sheet according to its thickness, ensuring accurate conveying. The upper surface of the machine body 1, near the film feeding mechanism 3, is fixedly connected to the adjustable film covering mechanism 5. The adjustable film covering mechanism 5 adjusts parameters such as pressure and temperature to firmly cover the PP sheet surface, completing the film covering process. The upper surface of the machine body 1 is provided with an adjustable positioning component 6, which is used to precisely adjust and position the PP sheet during the conveying process, ensuring the accuracy and stability of the sheet during film covering.

[0024] Furthermore, the adjustment and positioning assembly 6 includes a first fixed base 61 and a second fixed base 62. The first fixed base 61 and the second fixed base 62 serve as supporting components, providing an installation foundation for other structures of the adjustment and positioning assembly 6 and ensuring the stability of the entire assembly installation. The bottom of the first fixed base 61 is fixedly connected to one side of the upper surface of the body 1, and the bottom of the second fixed base 62 is fixedly connected to the other side of the upper surface of the body 1. There are two first fixed bases 61 and two fixed bases 62, and both first fixed bases 61 and second fixed bases 62 are mirror images of each other along the central axis of the body 1. An electric bidirectional screw 63 is provided on the inner side of the first fixed base 61. One end of the electric bidirectional screw 63 is fixedly connected to a drive motor, and the other end of the electric bidirectional screw 63 is rotatably connected to a bearing seat. The ends of the drive motor and the bearing seat away from the electric bidirectional screw 63 are both fixedly connected to the surface of the first fixed base 61. The drive motor drives the electric bidirectional screw 63 to rotate. Through the bidirectional rotation characteristic of the screw, the position of the adjustment frame 65 is adjusted, thereby changing the positioning of the PP sheet. Position: A guide rod 64 is fixedly connected to the inner side of the second fixed base 62. The guide rod 64 provides guidance for the movement of the adjusting frame 65, preventing the adjusting frame 65 from deviating during movement and ensuring the accuracy of adjustment. An adjusting frame 65 is connected between the electric bidirectional screw 63 and the outer side of the guide rod 64. Two adjusting frames 65 are provided, mirror-image arranged along the central axis of the first fixed base 61. The inner surface of one side of each adjusting frame 65 is threadedly connected to the outer surface of the electric bidirectional screw 63. The two adjusting frames 65 also... The inner surface on one side is movably connected to the guide rod 64. The two adjusting frames 65 cooperate with each other to clamp and position the PP sheet from both sides, ensuring that the sheet is fixed in position during the conveying process. The upper surfaces of the two adjusting frames 65 are sequentially provided with a feeding roller clearance groove 66 and a film coating roller clearance groove 67. The feeding roller clearance groove 66 provides installation and working space for the feeding roller without affecting the feeding roller's conveying of the sheet. The film coating roller clearance groove 67 provides operating space for the film coating roller, ensuring that the film coating roller can smoothly perform the film coating operation on the sheet.

[0025] Reference Figure 1 , Figure 2 ,and Figure 4A film cutting and traction assembly 7 is provided between the adjusting frame 65 and the upper surface of the machine body 1. This assembly is used for precise cutting of the film during lamination and for the traction and recycling of waste film, facilitating precise lamination of wide-width films. The film cutting and traction assembly 7 includes a mounting base 71 and a traction frame 75. The bottom of the mounting base 71 is fixedly connected to the upper surface of the adjusting frame 65. The mounting base 71 has an L-shaped mounting frame structure. The lower surface of the mounting base 71 is fixedly connected to an electric lifting frame 72. The electric lifting frame 72 can adjust the height of the film cutting blade 74 according to the actual requirements of the wide-width lamination process, achieving precise cutting of the film to be laminated. A film cutting motor 73 is fixedly connected to the outer surface of the electric lifting frame 72. The film cutting motor 73 serves as a power source, driving the film cutting blade 74 to rotate, thereby completing the film cutting operation. The output end of the film cutting motor 73 is fixedly connected to the film cutting blade 74. Driven by the traction motor, the film is cut to meet the required width for film covering. The bottom of the traction frame 75 is fixedly connected to the upper surface of the machine body 1. The outer surface of the traction frame 75 is fixedly connected to the traction motor 76, which provides power for the traction of the cut waste film. By driving the upper traction roller 77 to rotate, the film is transported to the external recycling mechanism or equipment. The output end of the traction motor 76 is fixedly connected to the upper traction roller 77. The end of the upper traction roller 77 is rotatably connected to the inner wall of the traction frame 75. The inner side of the traction frame 75 is rotatably connected to the lower traction roller 78. A gear transmission structure 79 is fixedly connected between the lower traction roller 78 and the outer side of the upper traction roller 77. The upper traction roller 77 rotates under the drive of the traction motor 76. The gear transmission structure 79 ensures the transmission synchronization between the upper traction roller 77 and the lower traction roller 78, realizing the continuous downward traction and recycling of the cut waste film.

[0026] Working Principle: In the operation of the fully automatic PP sheet laminating machine, the belt conveyor 2 starts first, automatically transferring the PP sheet into the machine body 1 through the cyclic rotation of the belt, laying the foundation for subsequent processes. At the same time, the film feeding mechanism 3 delivers the film required for lamination to the designated position according to the set parameters. The plate feeding mechanism 4 adjusts the conveying speed and position of the plate according to the thickness of the PP sheet to ensure its accurate forward movement. When the plate is delivered to the adjustment and positioning component 6, the drive motor drives the electric bidirectional screw 63 to rotate. The two adjustment frames 65, with the cooperation of the electric bidirectional screw 63 and the guide rod 64, clamp and position the plate from both sides. The plate feeding roller clearance groove 66 and the laminating roller clearance groove 67 are used to ensure that the normal operation of the plate feeding roller and the laminating roller is not affected, ensuring the accuracy and stability of the plate position. Subsequently, the laminating mechanism 5 adjusts the pressure, temperature and other parameters to firmly cover the surface of the plate with the film, completing the laminating process.

[0027] When the film width exceeds the requirements, the film cutting and traction assembly 7 comes into play: the electric lifting frame 72 adjusts the height of the film cutting blade 74 according to the actual process requirements, the film cutting motor 73 drives the film cutting blade 74 to cut the film, and the traction motor 76 drives the upper traction roller 77 to rotate. Through the gear transmission structure 79, it operates synchronously with the lower traction roller 78 to pull and recycle the cut waste film to the external mechanism, realizing the precise coating processing and waste disposal of wide films.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
