[0001] The utility model relates to the technical field of adjustment components, in particular to a PE stretch wrap film width adjustment component. Background Art

[0002] PE stretch film is a plastic film made primarily from polyethylene (PE). It features excellent stretchability, high transparency, strong puncture resistance, good self-adhesion, and moisture and dust resistance. It is primarily used for pallet packaging of goods, preventing them from scattering and becoming damaged during handling. It also provides dust and moisture protection, and maintains cleanliness. PE stretch film can also be used for both manual and machine packaging, making it a very practical packaging material. Existing PE stretch film requires a cutter to cut the film after wrapping it around the package. However, the width of the film cannot be adjusted during the wrapping process, requiring the replacement of PE stretch film with varying widths depending on the size of the package. This is not only cumbersome but also reduces the efficiency of wrapping. To address this issue, the present invention proposes a PE stretch film width adjustment assembly. Utility Model Content

[0028] Example

[0029] like Figures 1 to 3 As shown, the utility model proposes a PE stretch wrap film width adjustment component, comprising: a shell 1, a cover body 2 is hingedly provided on one side of the shell 1, which is convenient for limiting the PE stretch wrap film roll inside the shell 1; a fixed column 3 is fixedly arranged inside the shell 1, and the outer wall of the fixed column 3 is movably sleeved with a first set of rollers 4, which is convenient for making the PE stretch wrap film roll rotate stably; a square bucket 5 is connected to one side of the shell 1, and a cutting blade 6 is fixedly provided at the end of the square bucket 5 to facilitate cutting the PE stretch wrap film, and a limiting component 7 for adjusting the width of the PE stretch wrap film is fixedly provided inside the square bucket 5, which can quickly adjust the width of the PE stretch wrap film; a positioning component 8 is provided on the outer wall of the shell 1 for limiting the PE stretch wrap film to prevent the PE stretch wrap film roll from becoming loose.

[0030] like Figure 3 and Figure 4As shown, the limit component 7 includes a frame 701, and the frame 701 is arranged in a "冂" - shaped structure. A fixed rod 702 is fixedly arranged between the frames 701. A second roller 703 is movably sleeved on the outer wall of the fixed rod 702, which is convenient for guiding the PE stretch - wrapping film. A set of socket blocks 704 is movably sleeved on the outer wall of the fixed rod 702. One end of the socket block 704 is fixedly connected to a frame body 705. A plurality of limit rollers 706 are rotatably arranged inside the frame body 705, which is convenient for limiting the PE stretch - wrapping film and ensuring stable rotation while limiting. A regulating screw rod 707 is threadedly penetrated through the upper surface of the frame 701. The lower end of the regulating screw rod 707 is rotatably provided with a connecting block 708. A set of linkage rods 709 is rotatably arranged on the connecting block 708. One end of the linkage rod 709 is rotatably connected to the socket block 704, which is convenient for driving the socket block 704 to move horizontally relatively or oppositely simultaneously. The upper end of the regulating screw rod 707 penetrates through the square hopper 5 and extends to be connected with a rotating cap 710, which is convenient for manual rotation adjustment.

[0031] As Figure 3 shown, the positioning component 8 includes a linkage rod 81 that movably penetrates through the housing 1. One end of the linkage rod 81 is fixedly connected to a pull block 82, which is convenient for pulling the linkage rod 81 to move. The other end of the linkage rod 81 is fixedly connected to an arc - shaped pressing block 83, and a plurality of convex blocks are arranged on the inner ring surface of the arc - shaped pressing block 83, which can stably limit the PE stretch - wrapping film roll. A spring 84 is sleeved on the outer wall of the linkage rod 81. One end of the spring 84 is fixedly connected to the housing 1, and the other end of the spring 84 is fixedly connected to the arc - shaped pressing block 83, which can provide a thrust force for the arc - shaped pressing block 83.

[0032] Furthermore, a handle 9 is fixedly arranged on the outer wall of the housing 1, which is convenient for taking the housing 1 for winding and packaging.

[0033] Secondly, a transparent window 10 is arranged on one side of the cover body 2, which is convenient for observing the remaining amount of the PE stretch - wrapping film roll inside the housing 1.

[0034] Furthermore, a rotating rod 11 is rotatably arranged on the cover body 2. One end of the rotating rod 11 is fixedly connected to a clamping block 12. A clamping groove 13 is opened at one end of the fixed column 3, which can limit the cover body 2 on one side of the housing 1.

[0035] In addition, two guiding rollers 14 are rotatably arranged inside the housing 1, and the guiding rollers 14 are located at the connection between the housing 1 and the square hopper 5, which can guide the PE stretch - wrapping film and make it convey stably.

[0036] The operating principle of this embodiment is as follows: manually rotating the rotating rod 11 drives the clamping block 12 to rotate within the clamping slot 13, opening the cover 2. The pull block 82 is then manually pulled, which drives the arc-shaped pressing block 83 via the linkage rod 81. The rolled PE stretch film is placed inside the housing 1 and sleeved onto the outer wall of the first set of rollers 4. One end of the PE stretch film is then passed through the guide roller 14, the frame 701, and the square bucket 5 in sequence.

[0037] When adjusting the width of the PE stretch wrap film, manually rotate the rotating cap 710 according to the size of the package. The rotating cap 710 drives the connecting block 708 to move vertically by adjusting the threaded rod 707. The connecting block 708 drives the sleeve block 704 to move horizontally on the outer wall of the fixed rod 702 through the connecting rod 709. The sleeve block 704 drives the limiting roller 706 on the frame 705 to push the PE stretch wrap film, thereby limiting the PE stretch wrap film and adjusting the winding width of the PE stretch wrap film.

[0038] During wrapping, the pull block 82 is manually pulled. This moves the curved pressure block 83 via the linkage rod 81, releasing it from the outer wall of the PE stretch film roll. One end of the PE stretch film is then wrapped tightly against the packaged object. The PE stretch film, guided by the limiting rollers 706 and guide rollers 14, drives the first set of rollers 4 to rotate along the outer wall of the fixed column 3, thereby wrapping the PE stretch film roll around the package. After wrapping, the cutting blade 6 pushes against the PE stretch film to cut it. This allows for quick adjustment of the PE stretch film's wrapping width to accommodate packages of varying sizes, broadening its applicability and reducing the tedious process of changing PE stretch film widths, thereby improving packaging efficiency.

[0039] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
