TECHNICAL FIELD
[0001] The utility model relates to PE film winding and unwinding equipment technical field, concretely is a winding and unwinding device for PE film processing. BACKGROUND
[0002] PE wrapping film is also called heat shrinkable film, which is used for the sale and transportation of various products, and its main function is to stabilize, cover and protect the products. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinkage process, the film cannot produce holes. Since the shrink film is often used outdoors, it is necessary to add UV ultraviolet resistant agent. In the prior art, the winding and unwinding of PE wrapping film is realized by dividing the PE wrapping film into several segments and then winding by the rolling of the roller. After winding is completed, the product is finally taken out, packaged and transported. In the above process, the PE film is prone to looseness due to the improper tension adjustment of the winding mechanism, and the formed PE film is not easy to be taken down as a whole after winding on the winding mechanism. Therefore, we propose a winding and unwinding device for PE film processing. SUMMARY
[0003] The utility model aims at providing a winding and unwinding device for PE film processing to solve the problems raised in the background art.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a winding and unwinding device for PE film processing, comprising a base, a side plate is arranged above the base, a guide roller shaft, a first extrusion roller shaft, a transfer roller shaft and a winding roller are rotatably installed on the side surface of the side plate, a second extrusion roller shaft is arranged on the side surface of the first extrusion roller shaft, the second extrusion roller shaft is installed on a sliding table, a pull rod is connected to the side surface of the sliding table, the pull rod passes through the middle part of a limiting plate, and a fixed block is arranged at the tail end of the pull rod, a spring is sleeved on the pull rod, a limiting ring is sleeved on the winding roller, a connecting shaft is arranged at the end of the winding roller, and the end of the connecting shaft is inserted into a transmission shaft and locked by a positioning bolt.
[0005] In the above scheme, a foot wheel is arranged at the bottom of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This PE film processing winding and unwinding device has a simple and reasonable structural design and strong practicality. By setting a first extrusion roller shaft and a second extrusion roller shaft, and using a slide table, guide rod, pull rod, limiting plate, spring and fixing block in cooperation, the second extrusion roller shaft moves stably along the first extrusion roller shaft under the action of the spring, thereby clamping the PE film body from two directions, ensuring the stability of the PE film body during the winding process. By arranging two adjustable limiting rings on the winding roller, the position of the limiting rings can be adjusted according to the width of the PE film body, so that the PE film body is stably wound inside the two limiting rings, achieving a good anti-deviation effect. In addition, by setting a connecting shaft and a transmission shaft as transmission components, and connecting the two under the action of positioning bolts, the connection mechanism can be easily installed and disassembled, thereby making it easy to remove the whole material after winding.

[0017] Please see Figs. 1-3This utility model provides a technical solution: a winding and unwinding device for PE film processing, including a base 1. A side plate 31 is provided on the top of the base 1. A guide roller shaft 12, a first extrusion roller shaft 13, a transfer roller shaft 14, and a winding roller 15 are rotatably mounted on the side of the side plate 31. A second extrusion roller shaft 18 is provided on the side of the first extrusion roller shaft 13. The second extrusion roller shaft 18 is mounted on a slide table 19. A pull rod 21 is connected to the side of the slide table 19. The pull rod 21 passes through the middle of a limiting plate 22, and a fixing block 24 is provided at the tail end of the pull rod 21. A spring 23 is sleeved on the pull rod 21. A limiting ring 25 is sleeved on the winding roller 15. A connecting shaft 27 is provided at the end of the winding roller 15. The end of the connecting shaft 27 is inserted into a transmission shaft 28 and locked by a positioning bolt 29. In this device, there are two sets of the first extrusion roller shaft 13, the transfer roller shaft 14, and the second extrusion roller shaft 18.
[0018] By setting a first extrusion roller shaft 13 and a second extrusion roller shaft 18, and using a structure such as a slide table 19, a guide rod 2, a pull rod 21, a limiting plate 22, a spring 23, and a fixing block 24 in cooperation, the second extrusion roller shaft 18 moves stably toward the first extrusion roller shaft 13 under the action of the spring 23, thereby enabling the first extrusion roller shaft 13 and the second extrusion roller shaft 18 to clamp the PE film body from two directions, ensuring the stability of the PE film body during the winding process.
[0019] In the above solution, the bottom of the base 1 is provided with casters 11. The casters 11 are self-locking casters, which facilitate the movement of the equipment.
[0020] In the above scheme, the two transfer rollers 14 are mounted on the bracket 16, and a support column 17 is provided below the bracket 16. The bottom of the support column 17 is fixed to the base 1.
[0021] In the above scheme, the slide table 19 is movably sleeved on the guide rod 2.

[0022] In the above scheme, the two ends of the spring 23 are connected to the limiting plate 22 and the fixing block 24, respectively.
[0023] In the above solution, the limiting ring 25 has a groove, and a locking bolt 26 is screwed into the groove.

In addition, by setting the connecting shaft 27 and the drive shaft 28 as a transmission assembly, and by connecting the two under the action of the positioning bolt 29, it is convenient to install and disassemble the connecting mechanism, thereby making it easy to remove the entire material after winding.
[0025] Working principle:
[0026] This type of PE film processing winding and unwinding device winds the PE film body sequentially around the guide roller shaft 12, the first extrusion roller shaft 13, and the transfer roller shaft 14 before winding it onto the winding roller 15. Under the action of the spring 23, the second extrusion roller shaft 18 moves stably toward the first extrusion roller shaft 13, thereby clamping the PE film body from two directions, ensuring the stability of the PE film body during winding. By arranging two adjustable limiting rings 25 on the winding roller 15, the position of the limiting rings 25 can be adjusted according to the width of the PE film body, so that the PE film body is stably wound inside the two limiting rings 25. The motor 3 drives the winding roller 15 to rotate through the transmission assembly composed of the connecting shaft 27 and the transmission shaft 28, thereby stably winding the PE film body. Under the action of the positioning bolt 29, the two are connected, which facilitates the installation and disassembly of the connection mechanism, and makes it easy to remove the whole material after winding.
