Technical Field

[0001] This utility model relates to the field of heat shrink film processing technology, specifically to an antistatic polymer POF heat shrink film processing equipment. Background Technology

[0002] Polymer POF heat shrink film is a multi-layer co-extruded environmentally friendly heat shrink packaging material made primarily of polyolefins. Due to its excellent performance, it is widely used in the packaging field. Its main components are based on polyethylene, polypropylene, or their copolymers, and are formed into a multi-layer structure through co-extrusion. It has advantages such as outer layer abrasion resistance and antistatic properties, middle layer for regulating shrinkage rate and enhancing toughness, and inner layer for low-temperature heat sealing performance. Nowadays, in order to facilitate the division of heat shrink film during use, perforation equipment is used to perforate the film during production.

[0003] However, during the current film perforation process, uneven speed during film movement can cause folding or stretching. Furthermore, existing equipment does not flatten the perforation location, resulting in perforation deviation at the folds, which affects subsequent cutting and greatly impacts product quality and perforation uniformity. Utility Model Content

[0004] This invention provides an antistatic polymer POF heat shrink film processing equipment, which can effectively solve the problems mentioned in the background art, such as the film folding or stretching due to uneven speed during film perforation, and the lack of flattening treatment at the perforation position in existing equipment, resulting in perforation offset at the folds during perforation, affecting subsequent cutting and use, and greatly affecting product quality and perforation uniformity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an antistatic polymer POF heat shrink film processing equipment, including a processing fixing frame, wherein a punching component is provided on the side end of the processing fixing frame; The punching assembly includes a cutting processing plate; A cutting plate is snapped onto the top of the processing fixture, and several cutting hydraulic cylinders are equidistantly installed on the top of the processing fixture. A punching blade is snapped onto the bottom of the multiple cutting hydraulic cylinders. The top of the processing frame is welded with several fixed processing frames at equal intervals, and the top of the drilling processing knife is clamped with several moving limit ropes at equal intervals. Multiple movable limiting ropes are equipped with locking support frames at their bottom ends, and the locking support frames are rotatably connected to pressing limiting rollers on their side ends; The fixed processing frame is rotatably connected to a pulley on its inner side.

[0006] According to the above technical solution, the punching tool is placed inside the processing frame, and the movable limiting rope is rotatably connected to the fixed pulley.

[0007] According to the above technical solution, the movable limiting rope is installed through the top of the processing fixing frame; The input end of the cutting hydraulic cylinder is electrically connected to the output end of an external power source.

[0008] According to the above technical solution, a limit component is provided on the side end of the processing fixing frame; The limiting component includes a swing electric slide rail; Several swing electric slide rails are equidistantly embedded and installed inside the processing fixed frame, and a swing processing roller is installed at one end of each swing electric slide rail through a slide rail seat. The processing fixture has symmetrically installed clamping electric slide rails on the bottom inner side, and the top of the clamping electric slide rails is equipped with a clamping fixing plate through a slide rail seat. The bottom of both ends of the processing fixing frame is provided with entry and exit restriction holes, and the side end of the clamping fixing plate is provided with a number of sliding combination holes at equal intervals.

[0009] According to the above technical solution, the oscillating processing roller is slidably installed inside the processing fixing frame, and the oscillating processing roller is sleeved and installed inside the sliding combination hole.

[0010] According to the above technical solution, the side end of the clamping and fixing plate is slidably attached to the inner end of the processing and fixing frame; The input ends of both the swing electric slide rail and the clamping electric slide rail are electrically connected to the output end of an external power supply.

[0011] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use. 1. Equipped with a punching component, the moving limit rope drives the positioning support frame to rise and fall. The pressing limit roller inside the positioning limit frame contacts the film, rolling and pressing it down. This continuously rolls and flattens the area near the cut. The cutting hydraulic cylinder drives the punching blade downward, pulling the moving limit rope, positioning support frame, and pressing limit roller to move, causing the pressing limit roller to separate from the film. At this point, the punching blade punches the film. Through the combination of flattening guidance and limiting during movement and separation during punching, the film can be steadily flattened during movement, while avoiding excessive stretching during punching that could cause the film to break. This allows for steady punching during continuous production, reducing the occurrence of punching position deviation and uneven punching due to wrinkles, greatly ensuring product quality.

[0012] 2. A limiting component is installed. The clamping electric slide rail drives the clamping fixing plate to move, restricting both sides of the film. This reduces the risk of the film deviating from its position during movement, which could lead to significant tilting and affect subsequent production. The oscillating electric slide rail drives the oscillating processing roller to move along the sliding combination hole. By using multiple sets of sliding restrictions at different positions, the force on the film is changed, achieving film movement and flattening. At the same time, it avoids excessive force and changes the film's tightness, ensuring the flatness and uniformity of the film during feeding and unloading, reducing the probability of film wrinkles, and ensuring the quality of products during continuous production.

[0016] Example: Figure 1-4 As shown, this utility model provides a technical solution: an antistatic polymer POF heat shrink film processing equipment, including a processing fixture 1, and a punching component 2 is provided on the side of the processing fixture 1; The punching assembly 2 includes a cutting processing plate 201, a cutting hydraulic cylinder 202, a punching processing knife 203, a fixed processing frame 204, a moving limiting rope 205, a clamping support frame 206, a pressing limiting roller 207, and a fixed pulley 208. A cutting plate 201 is snapped onto the top of the processing fixture 1. Several cutting hydraulic cylinders 202 are installed at equal intervals on the top of the processing fixture 1. A punching blade 203 is snapped onto the bottom of the multiple cutting hydraulic cylinders 202. The punching blade 203 is placed inside the processing fixture 1 to achieve steady cutting. Several fixed processing frames 204 are welded at equal intervals to the top of the processing fixed frame 1. Several movable limiting ropes 205 are clamped at equal intervals to the top of the drilling processing knife 203. The movable limiting ropes 205 are rotatably connected to the fixed pulley 208. The movable limiting ropes 205 are installed through the top of the processing fixed frame 1, so that the movable limiting ropes 205 can be steadily guided and supported when they move, ensuring the stability of the limit. Multiple movable limiting ropes 205 are equipped with a locking support frame 206 at their bottom ends, and a pressing limiting roller 207 is rotatably connected to the side end of the locking support frame 206. A fixed pulley 208 is rotatably connected to the inner side of the fixed processing frame 204; To ensure stable operation of the equipment, the input end of the cutting hydraulic cylinder 202 is electrically connected to the output end of an external power supply.

[0017] A limit component 3 is provided on the side end of the fixing frame 1; The limiting component 3 includes a swing electric slide rail 301, a swing processing roller 302, a clamping electric slide rail 303, a clamping fixing plate 304, an inlet / outlet limiting hole 305, and a sliding combination hole 306. Several swing electric slide rails 301 are equidistantly embedded in the inner side of the processing fixture 1. One end of the swing electric slide rail 301 is equipped with a swing processing roller 302 through the slide rail seat. The swing processing roller 302 is slidably installed in the inner side of the processing fixture 1 and sleeved in the inner side of the sliding combination hole 306 to realize the rolling and pushing of the film for processing, and to ensure the stability of the film limiting support. A clamping electric slide rail 303 is symmetrically installed on the bottom inner side of the processing fixture 1. A clamping fixing plate 304 is installed on the top of the clamping electric slide rail 303 through the slide rail seat. The side end of the clamping fixing plate 304 slides and fits against the inner end of the processing fixture 1 to achieve stable limiting processing. Both ends of the fixing frame 1 are provided with entry and exit restriction holes 305, and the side of the clamping fixing plate 304 is provided with a number of sliding combination holes 306 at equal intervals. To ensure stable operation of the equipment, the input terminals of both the swing electric slide rail 301 and the clamping electric slide rail 303 are electrically connected to the output terminal of an external power supply.

[0018] The working principle and usage process of this utility model are as follows: When punching a film, the operator pulls the film along the inlet and outlet restriction hole 305 into the inner side of the processing fixture 1, and through multiple swing processing rollers 302 to move it to the position of the cutting processing plate 201. The clamping electric slide rail 303 drives the clamping fixture 304 to move along the swing processing rollers 302 to restrict both sides of the film. The swing electric slide rail 301 drives the swing processing rollers 302 to move along the sliding combination hole 306, pulling the film to move and changing the tightness of the film. This ensures the flatness and uniformity of the film during feeding and discharging, and avoids positional deviation or wrinkles that may affect the punching alignment. During film movement, the pressing and limiting roller 207 on the inner side of the positioning support frame 206 contacts the film, rolling and pressing it down to flatten the cut area. When punching, the cutting hydraulic cylinder 202 drives the punching blade 203 to move downward. At this time, the punching blade 203 pulls the moving limiting rope 205, which is pulled along the fixed pulley 208 at the fixed processing frame 204. The positioning support frame 206 rises under the pulling action of the moving limiting rope 205, causing the pressing and limiting roller 207 to separate from the film. After separation, the punching blade 203 punches the film. By using guided pressing and synchronous lifting, the film movement is steadily restricted and guided, and the film is not stretched due to the pressure during punching, ensuring the accuracy and stability of the punching alignment.
