[0002] Traditional PP sheet laminating machines use a motor to drive guide rollers, which move the PP sheet to the film rollers. The film is then applied to the surface of the PP sheet by rotating the film rollers.

[0003] For example, Chinese patent CN217395725U discloses a PP sheet coating device, including a conveyor belt, a film roller, and a guide roller, which are used to adhere coated PP sheets. However, in this coating technology, a layer of dust or particulate matter adheres to the surface of the PP sheet during transport. During coating, this dust and particulate matter can easily accumulate between the film and the sheet, reducing the quality of the PP sheet. Utility Model Content

[0008] Furthermore, the driving mechanism includes a first support, a first driving roller, a driving motor, a second support, and a second driving roller. The first support and the second support are two sets, respectively arranged on both sides of the frame. The first driving roller is connected to the first support by a bearing, and the second driving roller is connected to the second support by a bearing. The driving motor is fixed to one side of the first support, and the conveying end of the driving motor is connected to the first driving roller by a coupling.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] like Figures 1 to 6 As shown, this utility model provides a PP sheet processing and laminating device, including a frame 1, a conveying mechanism 2, a driving mechanism 3, a cleaning mechanism 4, a film feeding mechanism 5, a cutting mechanism 6, and a detection switch 7. The frame 1 is constructed by welding four sets of uprights 11 and a crossbeam 12. The crossbeam 12 has a rectangular frame structure, and the four sets of uprights 11 are fixed at the four lower corners of the crossbeam 12. The conveying mechanism 2 is wound around the upper and lower sides of the crossbeam 12 and is rotatably connected to the crossbeam 12 via bearings to achieve a circulating conveying function for conveying PP sheets.

[0026] The conveying mechanism 2 uses a rubber conveyor belt with evenly spaced baffles 21 on its surface. The spacing between adjacent baffles 21 is slightly larger than the maximum length of the PP sheet, ensuring that the sheet is confined during conveying. The height of the baffles 21 is 5mm, which is less than the gap between the first drive roller 32, the second drive roller 35, and the conveyor belt (set to 8mm), avoiding interference with the pressing action of the drive rollers. The spacing of the baffles 21 can be adjusted according to the sheet specifications; for example, for a PP sheet with a length of 600mm, the baffle spacing is set to 620mm. The gap between the drive rollers and the conveyor belt can also be adjusted according to the sheet thickness to ensure the pressing effect.

[0027] The cleaning mechanism 4 is located between the input end of the conveying mechanism 2 and the film-laying mechanism 5, and includes a vacuum head negative pressure pipe 41, a vacuum head 42, and a flat nozzle 43. The vacuum head 42 is connected to the negative pressure pipe 41 through a flange. The negative pressure pipe 41 passes through the right side of the film-laying frame 51 and extends to the outside, connecting to an external negative pressure fan (not shown in the figure). The inlet direction of the flat nozzle 43 faces the input end of the conveyor belt and is parallel to the surface of the conveyor belt. Its width covers the entire width of the conveyor belt, which can efficiently adsorb dust and debris on the surface of the board.

[0028] The film feeding mechanism 5 includes film feeding frames 51 and film feeding rollers 52 symmetrically arranged on both sides of the frame 1. The two ends of the film feeding rollers 52 are rotatably connected to the film feeding frames 51 through bearings, and protective film rolls are wound on their surfaces. The negative pressure pipe 41 passes through the reserved hole in the right-side film feeding frame 51 and connects to the external pipeline.

[0029] The drive mechanism 3 includes a first support 31, a first drive roller 32, a drive motor 33, a second support 34, and a second drive roller 35. The first support 31 and the second support 34 are respectively fixed to both sides of the frame 1. The first drive roller 32 is horizontally mounted on the first support 31 via bearings, and the second drive roller 35 is mounted on the second support 34 via bearings. The drive motor 33 is bolted to the outside of the first support 31, and its output shaft is connected to the first drive roller 32 via a coupling. The gap between the first drive roller 32 and the second drive roller 35 and the surface of the conveyor belt is 8mm. When the sheet material passes through, the drive rollers press down and form a clamping force with the conveyor belt, pushing the sheet material forward. The first drive roller 32 and the second drive roller 35 are respectively close to the conveying mechanism 2 with a gap between them.

[0030] A cutting mechanism 6 is provided at the tail end of the frame 1. The cutting mechanism 6 includes a cylinder 61 and a blade 62. The blade 62 is fixedly connected to the movable end of the cylinder 61 and faces the conveying mechanism 2. A cylinder frame 63 is fixed on the second bracket 34, and the cylinder 61 is fixed on the cylinder frame 63. A detection switch 7 is provided on one side of the frame 1, and the detection switch 7 is electrically connected to the cylinder 61.

[0031] The conveying mechanism 2 is a conveyor belt, and a plurality of baffles 21 are provided on the conveying mechanism 2. The distance between two baffles 21 is greater than the length of the PP sheet, and the height of the baffles 21 is less than the gap between the first drive roller 32 and the second drive roller 35 and the conveying mechanism 2.

[0032] The detection switch 7 is a proximity switch or a Hall sensor. In this embodiment of the invention, a sensing element is provided on the baffle plate to cooperate with the detection switch 7. Specifically, the detection switch 7 is a proximity switch. When the baffle 21 at the end of the sheet reaches a set position, the proximity switch detects the signal from the metal baffle 21 and triggers the cutter action. Similarly, the detection switch 7 can also be a Hall sensor, which sends a control signal when the baffle 21 is detected, triggering the cutter to cut the PP sheet film.

[0033] The working principle of this utility model:

[0034] PP sheets are fed in by a conveyor belt. After the flat nozzle 43 removes surface impurities, the protective film released by the film-laying roller 52 covers the upper surface of the sheet. The drive roller presses the sheet together and drives it forward until the end of the sheet triggers the detection switch 7. The cylinder 61 controls the blade 62 to cut the protective film, completing the lamination process.

[0035] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
