[0007] The positioning plate is internally provided with two edge trimmers, and the inner side of the positioning plate is provided with a winding group and an auxiliary group. The winding group comprises a motor two and a winding roller, the output end of the motor two is connected with the winding roller, the auxiliary group comprises two rotating rods and two positioning rollers, and the two positioning rollers are respectively nested on the outer surfaces of the two rotating rods.

[0008] A further preferred embodiment: a motor is installed on the outside of the positioning plate, a double-ended screw is installed at the output end of the motor, and the other end of the double-ended screw is embedded in the inner wall of the positioning plate.

[0009] A further preferred embodiment: slide blocks are nested on both sides of the double-ended screw, and the slide blocks are threadedly connected to the double-ended screw. The two trimmers are respectively installed at the bottom of the two slide blocks.

[0010] A further preferred embodiment: a limiting groove is formed at the upper end of the positioning plate, and a positioning rod is fixedly installed on the top of each of the two slide blocks.

[0014] Beneficial effects:

[0015] 1. An auxiliary group, consisting of two rotating rods and two positioning rollers, plays a crucial role in the trimming process of metallized polypropylene film. Before the film is transported to the trimmer, the auxiliary group provides auxiliary positioning and guidance. As the film moves on the conveyor, the positioning rollers accurately control the film's position and direction, ensuring the film remains stable in the trimming area. This effectively reduces film deviation during the trimming process, allowing the trimmer to more accurately trim the film edges, greatly improving the trimming precision and quality. Simultaneously, the auxiliary group provides stable starting conditions for the entire trimming process, working in conjunction with subsequent trimmers, winding rollers, and other components to ensure efficient trimming, reduce defective products caused by unstable film position, improve production efficiency, and lower production costs.

[0016] 2. Equipped with a collecting roller, the take-up roller plays a crucial role in the trimming machine by winding up the trimmed film. Driven by a motor, its rotation neatly and orderly winds up the trimmed film for easy subsequent processing. The outer surface of the take-up roller is made of rubber, which, in conjunction with the limiting roller, greatly increases the friction between the roller and the film during the winding process. This prevents the film from loosening during winding, ensuring tightness and stability. At the same time, the rubber material reduces wear on the film, minimizing damage to the film surface during winding and improving product quality. Furthermore, the stable operation of the take-up roller can adapt to the winding requirements of trimmed films at different speeds, working closely with the entire trimming process to ensure that the trimmed film is collected in a timely and efficient manner, improving the overall working efficiency of the trimming machine and ensuring production continuity.

[0017] 3. The system incorporates a collection box, a core component of the waste disposal process. Two staggered, downward-sloping baffles inside effectively guide and block waste generated during trimming. Instead of accumulating at the inlet and causing blockages, the waste is organized within the box by the baffles, facilitating storage and cleaning. Anti-slip strips on the inner wall of the collection box inlet, with an arc-shaped inner surface and a hollow interior, not only limit the flow of the conduit and increase friction between the conduit and the inlet to prevent slippage and ensure smooth passage of waste into the collection box, but also prevent leakage and waste at the inlet. The transfer box, conduit, and collection box work together to smoothly transfer waste from the trimming area to the collection area. The entire collection process is efficient and environmentally friendly, reducing manual waste cleaning workload, improving the cleanliness of the production site, and promoting standardized production management.

[0018] 4. In summary, this trimming machine for producing metallized polypropylene film, with its structure including a take-up roller and a collection box, helps to accurately position and guide the film, reducing trimming deviation, improving trimming accuracy and quality, laying a stable foundation for subsequent processes, and ensuring efficient trimming. The take-up roller is driven by a motor, and its rubber surface, combined with a limiting roller, ensures tight and stable film winding, reduces wear, adapts to different speed requirements, and improves the overall working efficiency of the trimming machine. The staggered baffles inside the collection box guide the orderly accumulation of waste, and the imported anti-slip strips ensure that waste enters the box smoothly. The entire collection process is efficient and environmentally friendly, reduces manual cleaning, and contributes to standardized production management. Attached Figure Description

[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0025] Please see Figures 1-4 In this embodiment of the present invention, a trimming machine for producing metallized polypropylene film includes: a support 1, a conveyor 2 disposed inside the support 1, a positioning plate 3 nested outside the support 1, a transfer box 4 disposed at one end of the support 1, a guide tube 5 embedded on one side of the transfer box 4, a collection box 6 disposed on one side of the transfer box 4, and the other end of the guide tube 5 embedded in the collection box 6; two trimmers 7 are disposed inside the positioning plate 3, and a winding group 8 and an auxiliary group 9 are disposed inside the positioning plate 3, the winding group 8 including a motor 801 and a winding roller 8. 02. The output end of motor 801 is connected to the take-up roller 802. The auxiliary group 9 includes two rotating rods 901 and two positioning rollers 902. The two positioning rollers 902 are nested on the outer surface of the two rotating rods 901 respectively. The collection box 6 is provided with two baffles 601. The two baffles 601 are staggered and inclined downwards. The transfer box 4 and the guide tube 5 are both inclined towards the collection box 6. The inner wall of the inlet of the collection box 6 is provided with anti-slip strips 602. The inner side of the anti-slip strips 602 is arc-shaped and hollow inside.

[0026] Metallized polypropylene film is placed on conveyor 2. The conveyor 2, through its transmission, transports the film to the working area of ​​the trimming machine. Conveyor 2 provides power and a transport path for the film's movement. During transport, the film passes inside the positioning plate 3. Two trimmers 7 on the positioning plate 3 trim the edges of the film, removing excess material. Simultaneously, motor 801 in the winding group 8 drives the winding roller 802 to rotate, winding the trimmed film for subsequent processing. The two rotating rods 901 and two positioning rollers 902 in the auxiliary group 9 assist in positioning and guiding the film, ensuring a stable position and orientation during trimming. Waste generated during trimming is transferred by conveyor 2 into the transfer box 4. Since both the transfer box 4 and the guide tube 5 are inclined towards the collection box 6, the waste enters the collection box 6 under gravity through the guide tube 5. After entering the collection box 6, the waste is blocked and guided by two staggered and downward-sloping baffles 601 inside the collection box 6, ensuring a more orderly descent. Waste is piled up inside the collection box 6 to prevent direct accumulation at the inlet and blockage. An anti-slip strip 602, with an arc-shaped inner side and a hollow interior, is installed on the inner wall of the inlet of the collection box 6. This further limits one end of the guide tube 5, making the connection between the guide tube 5 and the collection box 6 more stable. The anti-slip strip 602 increases the friction between the guide tube 5 and the inlet, preventing the guide tube 5 from slipping at the inlet and ensuring that waste can smoothly enter the collection box 6. By setting two edge trimmers 7, both sides of the film can be trimmed simultaneously, improving trimming efficiency and reducing the time required for film trimming. This arrangement helps improve the production efficiency of metallized polypropylene film. Simultaneously, the placement of the transfer box 4, conduit 5, and collection box 6 allows waste to be smoothly transferred from the trimming area to the collection area. Furthermore, the baffle 601 design within the collection box 6 facilitates the orderly accumulation of waste, making storage and cleaning easier. The rotating rod 901 and positioning roller 902 of the auxiliary group 9 provide excellent positioning and guidance for the film, ensuring a stable position and orientation during trimming, thereby improving trimming accuracy and quality, and reducing trimming defects caused by film misalignment. The anti-slip strip 602 at the inlet of box 6 effectively increases the friction between the waste and the inlet, preventing the waste from slipping at the inlet and ensuring that all the waste can enter the collection box 6, avoiding waste leakage and waste. It also reduces the workload of manually cleaning the waste at the inlet. The layout of each component is compact. For example, the positioning plate 3 integrates the trimmer 7, the winding group 8 and the auxiliary group 9. The transfer box 4 and the collection box 6 are connected by the conduit 5 and are set at an angle. This design saves space and ensures the coordinated work between the components, improving the overall performance and practicality of the trimmer.

[0027] In this embodiment of the utility model, a motor 301 is installed on the outer side of the positioning plate 3, and a double-ended screw 302 is installed at the output end of the motor 301. The other end of the double-ended screw 302 is embedded in the inner wall of the positioning plate 3. Slide seats 303 are nested on both sides of the double-ended screw 302. The slide seats 303 and the double-ended screw 302 are threaded together. Two trimmers 7 are respectively installed at the bottom of the two slide seats 303. A limiting groove 304 is opened at the upper end of the interior of the positioning plate 3. A positioning rod 305 is fixedly installed on the top of the two slide seats 303. The positioning rods 305 can be embedded in the limiting groove 304. The positioning rods 305 and the limiting groove 304 are slidably connected.

[0028] When motor 301 starts, its output drives the double-ended screw 302 to rotate. Since the threads on both sides of the double-ended screw 302 rotate in opposite directions, and the slide block 303 is threadedly connected to the double-ended screw 302, the two slide blocks 303 will move relative to or away from each other along the axial direction of the double-ended screw 302. When the slide block 303 moves, the trimmer 7 installed at the bottom of the slide block 303 also moves accordingly. Simultaneously, the positioning rod 305 at the top of the slide block 303 slides within the limiting groove 304. The existence of the limiting groove 304 restricts the positioning rod 305 to only slide within the limiting groove 304. The slide block 303 moves in a specific direction, ensuring its stability during movement. It prevents the slide block 303 from rotating with the double-headed screw 302, allowing it to move smoothly along the axial direction. This ensures the trimmer 7 can precisely trim the film edges. The distance between the two trimmers 7 can be easily adjusted by the motor 301 driving the double-headed screw 302. In actual production, different specifications of metallized polypropylene films require trimming operations of different widths. This adjustable structure allows the trimmer to quickly adapt to the trimming needs of various film products, greatly improving efficiency. This significantly improves the versatility and applicability of the equipment, eliminating the need to replace specific trimming devices for different film specifications, thus saving production and time costs. The sliding connection between the positioning rod 305 on the top of the slide 303 and the limiting groove 304 provides stable guidance for the movement of the slide 303. This ensures that the trimmer 7 remains stable during movement, without shaking or shifting, thereby enabling precise trimming of the film edges. This improves the accuracy and quality of trimming, and high-precision trimming reduces the product scrap rate caused by substandard trimming, thus enhancing efficiency. A high product yield rate helps companies improve their economic efficiency. The structure is mainly composed of common components such as motor 301, double-headed screw 302, slide 303, positioning rod 305, and limiting groove 304. The structure is relatively simple. The simple structure not only reduces the manufacturing difficulty and cost of the equipment, but also reduces the probability of failure during equipment operation. Even if a failure occurs, due to the simple structure, maintenance personnel can quickly troubleshoot and repair the problem, improving the operational stability and maintenance convenience of the equipment, reducing equipment downtime, and ensuring the continuity of production.

[0029] In this embodiment of the utility model, the positioning plate 3 has sliding grooves 306 on both the left and right sides of its inner wall. A rotating shaft 307 is embedded inside the sliding groove 306. Springs 308 are installed at both ends of the rotating shaft 307. The upper end of the springs 308 is installed on the upper end of the inner wall of the sliding groove 306. A limiting roller 309 is nested on the outer surface of the rotating shaft 307. The limiting roller 309 and the rotating shaft 307 are movably connected. The auxiliary group 9 is located in front of the take-up roller 802, and the trimmer 7 is located between the auxiliary group 9 and the take-up roller 802. The limiting roller 309 is located above the take-up roller 802. The outer surfaces of the limiting roller 309 and the take-up roller 802 are both made of rubber.

[0030] When the trimming machine starts working, the film moves towards the take-up roller 802 under the drive of the conveyor 2. During this process, the rotating shaft 307 in the sliding grooves 306 on both sides of the inner wall of the positioning plate 3 can be flexibly adjusted up and down according to the film thickness and winding situation under the action of the spring 308. Since the limiting roller 309 is nested on the outer surface of the rotating shaft 307 and the two are movably connected, the limiting roller 309 can rotate on the surface of the rotating shaft 307. When the trimmed film is wound up by the take-up roller 802, the limiting roller 309 will always be in close contact with the film on the take-up roller 802 under the elastic force of the spring 308. Both the outer surfaces of roller 09 and the take-up roller 802 are made of rubber, increasing friction and preventing the film from loosening during winding, thus ensuring the tightness and stability of the winding. Simultaneously, the positioning roller 902 of the auxiliary group 9 first assists in positioning and guiding the film. After the film is trimmed by the trimmer 7, it reaches the take-up roller 802. At this point, the limiting roller 309 plays an auxiliary role in film winding, optimizing the quality of waste material winding: through the cooperation of spring 308, rotating shaft 307, and limiting roller 309, it can automatically adapt to thickness changes during film winding. The limiting roller 309 always remains in close contact with the film, preventing it from... The looseness during winding improves the compactness and regularity of the waste film, which is beneficial for subsequent centralized processing of the film and reduces storage space waste and potential scattering problems caused by loose film. The adjustable limit roller 309 can handle winding of films of different thicknesses. Whether the film is thin or thick, the self-adjustment of the spring 308 ensures that the limit roller 309 functions effectively, improving the trimming machine's adaptability to various production scenarios and expanding the equipment's application range. The rubber material of the limit roller 309 and the surface of the winding roller 802 reduces damage to the film during winding. This reduces wear and tear, while also reducing the impact force on the take-up roller 802 during operation, extending the service life of the take-up roller 802 and related transmission components, reducing maintenance costs and downtime caused by frequent component replacements, and ensuring continuous and stable production. The limit roller 309, auxiliary group 9, trimmer 7, and take-up roller 802 form an orderly collaborative working mechanism. Auxiliary group 9 ensures stable film conveying, trimmer 7 completes the trimming task, and limit roller 309 and take-up roller 802 work together to collect the film. Each component performs its own function and cooperates with each other, improving the overall working efficiency and performance of the trimming machine.

[0031] Working principle: During the film transport stage, the metallized polypropylene film is placed on the conveyor 2 inside the support 1. The conveyor 2 provides power and a transport path for the film, transporting it to the working area of ​​the trimming machine. The two rotating rods 901 and two positioning rollers 902 of the auxiliary group 9 play a role in assisting the positioning and guiding of the film. In the positioning and trimming stage, the film passes through the inside of the positioning plate 3 during transport. The two trimmers 7 on the positioning plate 3 can trim the edges of the film. The double-headed screw 302 is driven to rotate by the motor 301 on the outside of the positioning plate 3. Since the threads on both sides of the double-headed screw 302 turn in opposite directions, the two slides 303 connected to the slide 303 will move relative to or away from each other, driving the trimmers 7 installed at the bottom of the slides 303 to move, thereby adjusting the trimming width to adapt to different specifications of film. The positioning rod 305 at the top of the slide 303 slides in the limiting groove 304 to ensure the stable movement of the slide 303 and ensure that the trimmers 7 trim accurately. In terms of waste collection, the trimming... The generated waste is transferred to transfer box 4 via conveyor 2. Since both transfer box 4 and conduit 5 are inclined towards collection box 6, the waste enters collection box 6 through conduit 5 under gravity. Two staggered, downward-sloping baffles 601 inside collection box 6 guide the waste to accumulate in an orderly manner, preventing blockage of the inlet. Anti-slip strips 602 on the inner wall of the inlet limit the conduit 5, increasing friction and preventing it from slipping, ensuring the waste smoothly enters collection box 6. During the film winding process, motor 80 of winding group 8... 1. The winding roller 802 is driven to rotate, and the trimmed film is wound up. The rotating shaft 307 in the sliding groove 306 on both sides of the inner wall of the positioning plate 3 is flexibly adjusted up and down according to the film thickness and winding situation under the action of the spring 308. The limiting roller 309 is nested on the rotating shaft 307 and is always in close contact with the film on the winding roller 802 under the elastic force of the spring 308. Since the outer surface of the limiting roller 309 and the winding roller 802 are both made of rubber, the friction is increased, ensuring that the film is wound tightly and stably.
