Description

Technical Field

[0001] This utility model relates to the technical field of food preservation film processing, specifically to a novel food preservation film winding device. Background Technology

[0002] Plastic wrap is a type of plastic packaging product, usually made from ethylene through a polymerization reaction. Plastic wrap can be divided into three main categories: the first is polyethylene, abbreviated as PE; the second is polyvinyl chloride, abbreviated as PVC; and the third is polyvinylidene chloride, abbreviated as PVDC.

[0003] To meet the packaging and sales needs of cling film, it is necessary to perform a winding process. An existing automated winding device for cling film production, such as the one described in patent publication number CN218595635U, uses a first cleaning brush and a second cleaning brush. Because a telescopic spring is installed between the first and second cleaning brushes, the elasticity of the spring allows the cling film to be placed between them. During winding, the first and second cleaning brushes clean dust particles adsorbed on the surface of the cling film, preventing dust from adhering to the film and affecting its quality.

[0004] However, the device has a problem with loose winding, resulting in a loose finished roll, which affects the final effect and makes it less practical. Utility Model Content

[0024] Please see Figure 1-4A novel cling film winding device includes a base 1, a winding frame 2, a winding motor 3, a vertical plate 4, a sliding sleeve 5, a sliding rod 6, a connecting piece 7, a spring 8, a connecting frame 9, a fixed brush 10, a second sliding sleeve 11, a second sliding rod 12, a handle 13, and a movable brush 14. The top left rear side of the base 1 is connected to the bottom side of the winding frame 2, and the upper outer side of the winding frame 2 is connected to the inner side of the winding motor 3. The output end of the winding motor 3 is provided with a shaft structure, and the top center of the base 1 is connected to a set of... The bottom sides of the vertical plates 4 are connected. A set of sliding sleeves 5 is respectively installed on the inner side of the upper part of the two sets of vertical plates 4. The inner wall of each set of sliding sleeves 5 is slidably connected to the outer wall of a set of sliding rods 6. The rear side of the sliding rods 6 is connected to the middle of the front side of the connecting piece 7. A spring 8 is connected to the outer side of the front side of the connecting piece 7 and the outer side of the sliding sleeves 5 on the rear side of the vertical plate 4. The front sides of the two sets of sliding rods 6 are respectively connected to the middle lines of the left and right ends of the rear side of the connecting frame 9. A fixed brush 10 is connected to the bottom side inside the connecting frame 9. The inner side of the top of the connecting frame 9 is connected to the sliding sleeves 5. The outer side of the slide sleeve 11 is connected to the inner wall of the slide rod 12, which is slidably connected to the outer wall of the slide rod 12. The top of the slide rod 12 is connected to the middle of the bottom side of the handle 13, and the bottom of the slide rod 12 is connected to the middle of the top side of the movable brush 14. The take-up sleeve is fixed to the outside of the shaft structure. While holding the handle 13, the slide rod 12 slides upward inside the slide sleeve 11, causing the movable brush 14 and the fixed brush 10 to separate by a certain gap. The plastic wrap is passed through this gap and fixed to the take-up sleeve. Then the handle is released. Under the influence of gravity, slide bar 12 slides down inside slide sleeve 11. The moving brush 14 and the fixed brush 10 press against the outer side of the cling film at this part. Then, the winding motor 3 runs, and the winding sleeve rotates. It is elastically contracted by two sets of springs 8. The connecting piece 7 causes slide bar 6 to generate a forward force inside slide sleeve 5. Then, the fixed brush 10 and the moving brush 14 are connected through the connecting frame 9. They act on the surface of the cling film to wipe it and pull it forward to reduce wrinkles and make the winding tighter.

[0025] It also includes a counterweight 15, with the lower outer side of the slide bar 12 connected to the middle inner side of the counterweight 15; the counterweight 15 can increase gravity, which acts on the moving brush 14 to increase the downward pressure on the plastic wrap and improve its practicality.

[0026] It also includes an oil injection nozzle 16, which is provided on the lower middle part of the front side of the second sliding sleeve 11; oil can be injected into the inner wall of the second sliding sleeve 11 through the oil injection nozzle 16 for convenient lubrication and maintenance.

[0027] It also includes an oil filling cap 17, and the outer side of the oil filling nozzle 16 and the inner side of the oil filling cap 17 can be detachably installed; after the oil filling cap 17 is installed on the outer side of the oil filling nozzle 16, the inside of the oil filling nozzle 16 can be sealed and protected, improving reliability.

[0028] The shaft structure includes shaft 18, threaded head 19, baffle 20, and threaded cap 21. The output end of the take-up motor 3 is connected to the left side of shaft 18. The outer side of the left part of shaft 18 is connected to the inner side of baffle 20, and the right side of shaft 18 is connected to the inner side of threaded head 19. The outer side of threaded head 19 is detachably screwed to the inner side of threaded cap 21. After the take-up sleeve is put on the outside of shaft 18, it is blocked by the left side of baffle 20, and the threaded cap 21 is screwed on the outside of threaded head 19 on the right side to tighten the take-up sleeve, so that the take-up sleeve and shaft 18 are relatively fixed, which is convenient for loading and unloading.

The top center of the rewind rack 2 is connected to one side of the adjustable lamp post 22, and the other side of the adjustable lamp post 22 is connected to the outer center of the lampshade 23. The bulb 24 is installed inside the lampshade 23. The adjustable lamp post 22 can provide adjustable support for the lampshade 23, and the bulb 24 provides illumination. The lampshade 23 guides the light to the bulb 24, thus optimizing the lighting environment.

[0030] In summary, when using a novel plastic wrap winding device, the winding sleeve is placed over the outside of the shaft 18, blocked by the left side of the baffle 20, and screwed onto the outside of the threaded head 19 by the threaded cap 21 on the right side, tightening the winding sleeve to fix it relative to the shaft 18. While holding the handle 13, the sliding rod 12 slides upwards inside the sliding sleeve 11, causing the moving brush 14 and the fixed brush 10 to separate by a certain gap. One side of the plastic wrap passes through this gap and is fixed to the winding sleeve. Then, the handle 13 is released, and under gravity, the sliding rod 12 slides down inside the sliding sleeve 11. The moving brush 14 and the fixed brush 10 press against the outside of that part of the plastic wrap. The counterweight 15 increases the gravity, further enhancing the effect. The moving brush 14 increases the pressure on the cling film downwards, and then the winding motor 3 runs, connecting the winding sleeve to rotate. Under the elastic contraction action of two sets of springs 8, the connecting piece 7 causes the slide rod 6 to generate a forward force within the slide sleeve 5. This force is then connected to the fixed brush 10 and the moving brush 14 via the connecting frame 9, acting on the surface of the cling film to wipe it and pull it forward, reducing wrinkles and making the winding tighter. In addition, oil can be injected into the inner wall of the slide sleeve 11 through the oil nozzle 16 for convenient lubrication and maintenance. After installing the oil nozzle 17 on the outside of the oil nozzle 16, the inside of the oil nozzle 16 can be sealed and protected. The adjustable lamp post 22 can adjust the support of the lamp cover 23, and the bulb 24 provides illumination. The lamp cover 23 guides the light to the bulb 24, optimizing the lighting environment.
