[0001] The utility model relates to the technical field of POE film heat shrinkage, in particular to a heat shrinkage device for POE film processing. Background Art

[0002] Poe heat shrink film is widely used in the sales and transportation of various products due to its high puncture resistance, good shrinkage and certain shrinkage stress. It mainly plays the role of stabilizing, covering and protecting products, especially in the combined packaging of irregular-shaped items or commodities. It can not only meet the functions of moisture-proof and dust-proof, anti-touch and tamper-proof, transparent display, etc. of commodities, but also increase the attractiveness of product appearance. It can also be used to replace various paper boxes to save packaging costs.

[0003] Although the existing heat shrink device can efficiently complete the drying of heat shrinkable film, the surface of the POE film is not stretched during drying, which makes its surface prone to wrinkles. In addition, the POE film may deviate during the drying and transmission process, affecting the quality of the finished product. Therefore, we propose a heat shrink device for POE film processing.

[0023] Please see the attached Figure 1 -Attached Figure 4The utility model relates to a heat shrink device for processing poe film, comprising a box body 1, a threaded rotating column 2 is rotatably connected to the middle part of the top side of the box body 1, and the bottom outer wall of the threaded rotating column 2 is threadedly connected to a sleeve 3. A sliding groove 4 is opened in the middle of the rear side of the sleeve 3, and one end of the fixing rod 5 is slidably connected to the inside of the sliding groove 4, and the other end of the fixing rod 5 is fixedly connected to the inner wall of the box body 1. The bottom end of the sleeve 3 is fixedly connected to the middle plate 6. The left and right sides of the middle plate 6 are provided with side plates 1, and the separated sides of the two side plates 17 are provided with side plates 2 8. The middle plate 6 and the left and right sides of the inner side of the side plates 17 and the adjacent sides of the two side plates 2 8 are rotatably connected to the rotating rod 9. The outer wall of the front end of the rotating rod 9 is threadedly connected to a fastening nut 10. The middle side of the outer wall of the rotating rod 9 is fixedly connected to two connecting blocks 11. The front and rear sides of the bottom of the middle plate 6, the side plates 1 7 and the side plates 2 8 are fixedly connected to the fixing plate 12, and a pressing roller 13 is rotatably connected between the two fixing plates 12.

[0024] Specifically, by rotating the threaded rotating column 2, the sleeve 3 moves downward. Since the sleeve 3 is provided with a sliding groove 4, and the sliding groove 4 is connected to the fixed rod 5, the fixed rod 5 provides a limit for the sleeve 3, so that the sleeve 3 can move downward and drive the middle plate 6 connected to it to move downward. Since the middle plate 6, side plate 1 7 and side plate 2 8 are connected by the connecting block 11 and the rotating rod 9, the side plate 1 7 and the side plate 2 8 move downward synchronously, so that the pressure roller 13 moves downward, reducing the distance between the pressure roller 13 and the poe film until the pressure roller 13 contacts and tightens the poe film. In addition, the fastening nut 10 is loosened by rotating it, and then the rotating rod 9 is rotated to drive the corresponding side plate 1 7 or side plate 2 8 on the connecting block 11 to adjust the angle to meet different tensioning requirements.

[0025] In the first embodiment, an electric push rod 14 is fixedly connected to the middle end of the bottom side of the box body 1, and the driving end of the electric push rod 14 is fixedly connected to an empty shell 15. The top surface of the empty shell 15 is provided with a plurality of air blowing ports 16. One end of a hose 17 is fixedly connected to one side of the bottom of the empty shell 15, and the other end of the hose 17 is fixedly connected to a fan. The outside of the fan is fixedly connected to a fan box 18, and one side of the fan box 18 is fixedly connected to the outer wall of the box body 1;

[0026] Specifically, hot air is generated by the fan in the bottom side fan box 18, enters the empty shell 15 through the hose 17, and then blown upward through multiple blowing ports 16 to perform heat shrinkage on the POE film being transported.

[0027] In the second embodiment, fixed shafts 19 are provided on both sides of the left and right sides of the interior of the box 1, and a conveying roller 20 is rotatably connected to the middle side of the outer wall of the fixed shaft 19. Limit plates 21 are provided on both sides of the front and rear sides of the outer wall of the conveying roller 20. One end of a telescopic column 22 is fixedly connected to the inner periphery of the limit plate 21, and the other end of the telescopic column 22 is fixedly connected to a limit block 24. The front and rear sides of the limit block 24 are inclined. A spring 23 is provided on the outer wall of the telescopic column 22, and one end of the spring 23 is fixedly connected to the inner wall of the limit plate 21, and the other end of the spring 23 is fixedly connected to the outer wall of the limit block 24. A plurality of limit grooves 25 are opened at equal intervals around the outer wall of the conveying roller 20, and the conveying roller 20 and the limit grooves 25 are correspondingly arranged;

[0028] Specifically, the POE film is limited by the limit plates 21 on both sides of the conveying roller 20, and at the same time, by pushing the corresponding limit plate 21, the limit block 24 inside it moves toward the inside of the limit plate 21, and drives the telescopic column 22 and the spring 23 to retract synchronously. When the limit plate 21 moves to the appropriate position, the telescopic column 22 and the spring 23 rebound, driving the limit block 24 to move toward the limit groove 25, completing the clamping operation, thereby adapting to POE films of different widths.

[0029] Working principle:

[0030] First, the POE film is limited by the limit plates 21 on both sides of the conveying roller 20, and at the same time, the corresponding limit plates 21 are pushed to make the limit blocks 24 inside thereof move toward the inside of the limit plates 21, and drive the telescopic columns 22 and springs 23 to retract synchronously. When the limit plates 21 move to the appropriate position, the telescopic columns 22 and springs 23 rebound, driving the limit blocks 24 to move toward the limit grooves 25, completing the clamping operation, thereby adapting to POE films of different widths; then the POE film is conveyed through the two conveying rollers 20. In this process, hot air is generated by the fan in the bottom side fan box 18, enters the empty shell 15 through the hose 17, and is then blown upwards through multiple blowing ports 16 to perform heat shrinkage on the POE film being conveyed; at the same time, in order to avoid wrinkles on the surface of the POE film Wrinkle, by rotating the threaded rotating column 2, the sleeve 3 moves downward, because the sleeve 3 is provided with a sliding groove 4, and the sliding groove 4 is connected to the fixed rod 5, the fixed rod 5 provides a limit for the sleeve 3, so that the sleeve 3 can move downward, and drive the middle plate 6 connected thereto to move downward, because the middle plate 6, side plate 1 7 and side plate 2 8 are connected by the connecting block 11 and the rotating rod 9, the side plate 1 7 and the side plate 2 8 move downward synchronously, so that the pressure roller 13 moves downward, reducing the distance between the pressure roller 13 and the poe film, until the pressure roller 13 contacts and tightens the poe film, and loosens it by rotating the fastening nut 10, and then rotates the rotating rod 9 to drive the corresponding side plate 1 7 or side plate 2 8 on the connecting block 11 to adjust the angle to meet different tensioning requirements. At this point, the entire work process ends.
