Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, and specifically discloses a plastic film edge removal and collection device. Background Technology

[0002] Plastic film, a widely used packaging material, is typically made of polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), and other resins. It is widely used in packaging and laminating processes for food, daily necessities, and industrial products. During the production and processing of plastic film, excess scraps are often generated due to the needs of film formation or lamination processes. These scraps must be removed promptly and effectively using cutting devices to ensure the neat edges of the finished film and the smooth progress of subsequent processes.

[0003] Currently, the industry commonly uses edge cutting devices to cut the edges of plastic films online. However, existing cutting devices still have many shortcomings in practical applications. First, the cutting mechanism of most devices is fixed in position, and the cutting distance cannot be flexibly adjusted according to the actual width of the plastic film, resulting in poor adaptability and difficulty in meeting the needs of producing products of different specifications. The adjustment process often requires machine shutdown and complex mechanical disassembly and assembly, which seriously affects production efficiency.

[0004] Secondly, existing devices lack an effective guidance and recycling mechanism for the cut scraps. After being cut, the scraps typically fall into the collection area by their own weight or through simple guiding structures, easily becoming entangled or stuck at the edges of the collection rollers. This not only increases the frequency and labor intensity of manual cleaning but can also obstruct the rotation of the collection rollers, leading to equipment downtime or even damage, severely impacting the continuity and stability of the production line. Furthermore, the disorderly accumulation of scraps can pose safety hazards and pollute the workshop environment. Therefore, designing a novel plastic film scrap collection device has become an urgent technical problem to be solved in this field. Utility Model Content

[0022] Example 1 Reference Figures 1-5 This embodiment provides a plastic film edge-removing and collecting device, including a frame 1, an edge-removing mechanism 2 and a guiding mechanism 3 disposed on the frame 1, and a collecting mechanism 4 disposed on one side of the frame 1; The trimming mechanism 2 includes a fixed base 21, both ends of which are rotatably connected to the frame 1. An adjustment component is provided on the fixed base 21, and a cutter 23 is provided on the adjustment component. The guiding mechanism 3 includes a guide roller 31 and a guide tube 33. The two ends of the guide roller 31 are fixedly connected to the frame 1, and the guide tube 33 is detachably connected to the frame 1. The collection mechanism 4 includes a collection frame 41 and a take-up roller 45 disposed on the collection frame 41. The cut edge film is guided to the take-up roller 45 for collection via the guide tube 33.

[0023] The position of the cutter 23 can be adjusted by the adjustable components to flexibly adjust the cutting distance according to the actual width of the plastic film. This is suitable for cutting scraps of plastic film of different widths and can meet the production needs of products of different specifications. The guide mechanism 3 can guide the cut edge film to the winding roller 45 so that the winding roller 45 can wind up the edge film. This can prevent the edge film from tangling or jamming on the winding roller 7, and can also avoid the safety hazards or environmental pollution caused by disorderly accumulation of edge film. The guided winding of the edge film achieves efficient and rapid recycling of plastic film scraps, improving the production efficiency of plastic film.

[0024] In this specific embodiment, the frame 1 is equipped with a transfer roller 5, a guide roller 6, and a take-up roller 7. The transfer roller 5 is located above the cutter 23, the guide roller 6 is located below the cutter 23, and the take-up roller 7 is located in the guiding direction of the guide roller 6. The transfer roller 5 conveys the plastic film. After the cutter 23 cuts the scraps of the plastic film, the cut plastic film is guided by the guide roller 6 and then wound up by the take-up roller 7, realizing the classified collection of the cut plastic film and the scrap film.

[0025] In a specific embodiment of this invention, the adjustment assembly includes an adjustment groove 22 formed in the fixed base 21, a hydraulic cylinder 25 disposed in the adjustment groove 22, and a cutter 23 mounted on the drive end of the hydraulic cylinder 25. The fixed base 21 is rotatably connected to the frame 1 via a rotating shaft 24. The rotating shaft 24 can be connected to a motor, which drives the rotating shaft 24 to rotate, synchronously driving the fixed base 21 to rotate, thereby adjusting the distance between the cutter 23 and the plastic film, so that the cutter 23 can cut the scraps of the plastic film. The hydraulic cylinder 25 drives the cutter 23 to move within the adjustment groove 22, thereby adjusting the position of the cutter 23, so as to cut plastic films of different widths or cut edge films of different widths.

[0026] In this specific embodiment, the frame 1 is provided with guide rods 32 symmetrical about the central axis of the frame 1 on the side where the edge film is discharged, and each guide rod 32 is provided with a corresponding guide tube 33. The guide rods 32 are fixedly connected to the frame 1.

[0027] In this specific embodiment, the inner sidewall of the frame 1 is provided with a mounting base 34. The mounting base 34 is rotatably connected to the frame 1 via a rotating shaft, and the guide tube 33 passes through the mounting base 34. The rotating shaft can be connected to a motor, which drives the shaft to rotate, synchronously rotating the mounting base 34, thereby adjusting the angle of the guide tube 33. This allows the edge film, guided by the guide rod 32, to better extend into the guide tube 33 and be guided to the take-up roller 45. Furthermore, a blower can be installed inside the guide tube 33 to blow the edge film out of the guide tube 33.

[0028] In a specific embodiment of this invention, the guide tube 33 includes a main guide tube 331 and a branch guide tube 332, which are connected by a clamp 333. Specifically, the main guide tube 331 passes through the mounting base 34, and the main guide tube 331 and the branch guide tube 332 are detachable, which facilitates adjustment of the length of the guide tube 33 and makes it easy to disassemble and store after the side film is collected.

[0029] In this specific embodiment, a movable seat 42 is provided on the collecting frame 41. The movable seat 42 is movably connected to the collecting frame 41 and located on one side of the take-up roller 45. The movable seat 42 has a through hole 47. By cooperating with the movable seat 42 and the through hole 47, the side film can be guided and directed, and the winding position of the side film on the take-up roller 45 can be adjusted to avoid the side film from gathering in one place during winding.

[0030] In this specific embodiment, the collecting rack 41 has a groove 43, and a lead screw 44 is provided in the groove 43. A slider 46 is threadedly connected to the outside of the lead screw 44, and the movable seat 42 is fixed to the top of the slider 46. It should be noted that the feed roller 5, take-up roller 7, take-up roller 45, and lead screw 44 are each connected to a driving device, such as a motor. In use, the motor drives the lead screw 44 to rotate, causing the slider 46 to move on the lead screw 44, which in turn moves the movable seat 42 on the top of the slider 46, thereby adjusting the winding position of the side film on the take-up roller 45, facilitating uniform winding by the take-up roller 45.

[0031] Working principle: Refer to Figures 6-7 The conveyor roller 5 conveys the plastic film, and the position of the cutter 23 is adjusted according to the width of the plastic film. Specifically, the hydraulic cylinder 25 drives the cutter 23 to move within the adjusting groove 22. During the conveying process, the cutter 23 cuts off the edge material. The cut edge film is guided by the guide roller 31 and guide rod 32 into the guide tube 33, and then passes through the through hole 47 of the moving seat 42 before being wound onto the take-up roller 45. The cut plastic film is then guided by the guide roller 6 and wound onto the take-up roller 7, completing the edge removal and collection of the plastic film.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
