Technical Field

[0001] This utility model relates to the field of anti-puncture wrapping film technology, specifically an anti-puncture wrapping film for machines that is easy to change rolls. Background Technology

[0002] Stretch film plays a vital role in many fields such as cargo packaging and logistics transportation. It can tightly wrap various products, providing protection and fixation. However, when a roll of machine-made stretch film is used up and a new roll needs to be replaced, it is inconvenient to quickly release and connect the outer walls of both ends of the stretch film. At the same time, the stretch film lacks a protective structure for the roll during operation, which makes it easy for the stretch film to be punctured to a certain extent, thus hindering the stability of equipment use. Utility Model Content

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Example 1: As Figures 1-4 The device includes a protective cover 100, and clamping assemblies for the wrapping film roller are installed on the top and bottom inner walls of the protective cover 100. The clamping assemblies include a positioning plate 200, and a first threaded tube 210 is fixedly installed on the top outer wall of the positioning plate 200. The outer wall of the first threaded tube 210 is fixedly connected to the inner wall of the protective cover 100. A threaded rod 240 is threadedly connected to the inner wall of the first threaded tube 210, and a bearing 241 is rotatably connected to the outer wall of the end of the threaded rod 240 near the wrapping film roller.

[0024] The specific application scenario of this embodiment is as follows: by setting up a protective cover 100, the stretch film roller is protected, which to a certain extent prevents the stretch film from being punctured or torn. By setting up a clamping component, the height of the threaded rod 240 and bearing 241 can be adjusted by rotating the handwheel 250, thereby allowing the threaded rod 240 and bearing 241 to be inserted into the hollow roller shaft 300. This facilitates flexible control of the insertion and separation of the threaded rod 240 and bearing 241 with the hollow roller shaft 300, making it convenient to change the stretch film roller.

[0025] Example 2: As Figures 1-3 The system includes a protective cover 100, and clamping assemblies for the wrapping film roller are fitted on the top and bottom inner walls of the protective cover 100. The clamping assemblies include a positioning disk 200, and a first threaded tube 210 is fixedly installed on the top outer wall of the positioning disk 200. The outer wall of the first threaded tube 210 is fixedly connected to the inner wall of the protective cover 100. A threaded rod 240 is threadedly connected to the inner wall of the first threaded tube 210. A bearing 241 is rotatably connected to the outer wall of the threaded rod 240 near the wrapping film roller. The protective cover 100 is U-shaped. A viewing window 110 is installed on the outer wall of the protective cover 100. Limiting rods 120 are evenly fixedly installed on the bottom and top inner walls of the protective cover 100. The limiting rods 120 are distributed in a circle around the center point of the bottom and top inner walls of the protective cover 100.

[0026] The specific application scenario of this embodiment is as follows: by setting a protective cover 100 to protect the stretch film on the outer wall of the stretch film roller, the surface of the stretch film is prevented from being scratched. By setting a limiting rod 120 to limit and guide the surrounding area of ​​the stretch film positioning plate 310 during installation, the installation and roll changing of the stretch film roller can be completed quickly and easily, thereby improving work efficiency.

[0027] Example 3: As Figure 4 and Figure 5 The top and bottom outer walls of the protective cover 100 are fixedly mounted with a support platform 220 via a first leg 221. A circular through hole is provided at the center of the support platform 220. The top of the support platform 220 is fixedly connected to a limiting plate 230 via a second leg 222. A second threaded pipe 231 is fixedly mounted on the top outer wall of the limiting plate 230. The second threaded pipe 231 and the first threaded pipe 210 are threadedly connected to a threaded rod 240. A handwheel 250 is fixedly mounted on the top outer wall of the threaded rod 240.

[0028] The specific application scenario of this embodiment is as follows: by rotating the threaded rod 240 in the first threaded tube 210 and the second threaded tube 231 by handing the handwheel 250, the handwheel 250 drives the threaded rod 240 to adjust its height, so that the threaded rod 240 can drive the bearing 241 to retract outward, so that the hollow roller shaft 300 in the wrapping film roller to be replaced is disengaged from the threaded rod 240 and the bearing 241.

[0029] Example 4: Figure 3 The stretch film roller includes a hollow roller shaft 300. A stretch film positioning disc 310 is fixedly installed on the top and bottom outer walls of the hollow roller shaft 300. The outer wall of the stretch film positioning disc 310 is engaged with the limiting rod 120 for positioning. The outer wall of the hollow roller shaft 300 is wound with stretch film. The top and bottom of the hollow roller shaft 300 are respectively engaged with two threaded rods 240 for insertion connection.

[0030] The specific application scenario of this embodiment is as follows: a hollow roller shaft 300 is set for winding the wrapping film. At the same time, the hollow roller shaft 300 is connected to the threaded rod 240 and the bearing 241 through a mating and insertion connection. After the bearing 241 is inserted into the inner wall of the hollow roller shaft 300, the bearing 241 is rotatably connected to the inner wall of the hollow roller shaft 300 through a mating and insertion connection, thereby facilitating the release of the wrapping film from the hollow roller shaft 300. A wrapping film positioning plate 310 is set to limit the top and bottom outer walls of the wrapping film.

[0031] The working principle of this utility model is as follows: When used by those skilled in the art, the protective cover 100 is installed on the wrapping machine, and the threaded rod 240 is rotated in the first threaded tube 210 and the second threaded tube 231 by handwheel 250. This causes the handwheel 250 to drive the threaded rod 240 to adjust its height, so that the threaded rod 240 can drive the bearing 241 to retract outward, causing the hollow roller shaft 300 in the wrapping roller to be replaced to disengage from the threaded rod 240 and the bearing 241. Then, the new wrapping roller is placed between the upper and lower positioning plates 200, so that the limiting rod 120 engages with the upper and lower wrapping positioning plates 310. Then, by handwheel 250 rotating the threaded rod 240, the threaded rod 240 can drive the threaded rod 240 and the bearing 241 to be inserted into the top and bottom inner walls of the hollow roller shaft 300, thereby quickly changing the wrapping roller and improving work efficiency.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
