Description

Technical Field

[0001] The utility model relates to the technical field of stretch film processing, and more specifically, to a stretch film fixing roller mechanism. Background Art

[0002] Stretch film, also known as stretch film or heat shrink film, was first produced in China using PVC as the base material and DOA as the plasticizer, which also acts as a self-adhesive agent. Plastic stretch film primarily provides primary surface protection for products, forming a compact, space-saving unit and saving packaging costs.

[0003] When used as packaging film, stretch film needs to be rotatably mounted on a winding roller to facilitate product packaging. When stretch film with different pore sizes is mounted on the winding roller, it is prone to wobble. This wobble relative to the winding roller not only causes wear on the edges of the stretch film but also affects the wrapping effect on the product. To address this issue, the present invention provides a stretch film fixing roller mechanism. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a wrapping film fixing roller mechanism, which has the advantages of reducing shaking and improving wrapping effect.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1-2 As shown, the utility model provides a wrapping film fixing roller mechanism, including: a lower connecting plate 1, an upper connecting plate 2, and a support assembly 3. A first connecting tube 10 extends upward from the center of the lower connecting plate 1 and passes through it up and down. A second connecting tube 20 extends downward from the center of the upper connecting plate 2 and passes through it up and down. The second connecting tube 20 is detachably arranged on the outer surface of the first connecting tube 10. The support assembly 3 includes: a spring group 30, a support plate 31, and a telescopic plate 32. The spring group 30 is evenly arranged on the outer surface of the first connecting tube 10, and movable grooves are arranged on both sides of the support plate 31. Several support plates 31 are arranged around the first connecting tube 10. The spring group 30 is fixedly connected to the side of the support plate 31 close to the first connecting tube 10. The two ends of the telescopic plate 32 are respectively movably restricted in the movable grooves of the two adjacent support plates 31. The support plate 31 and the telescopic plate 32 can shrink or expand axially along the first connecting tube 10. When the cylindrical wrapping film is put on the device, the upper connecting plate 2 is disconnected from the lower connecting plate 1, and the inner tube of the wrapping film is put on the outer surface of the support assembly 3. Under the action of the spring, the support plate 31 can fit tightly on the inner tube of the wrapping film, so that the wrapping film cannot shake. At the same time, since the first connecting tube 10 and the second connecting tube 20 are through-through, and the apertures of the first connecting tube 10 and the second connecting tube 20 remain unchanged, the wrapping film fixing roller mechanism can be put on the rotating shaft of the winding device as a whole.

[0025] In this embodiment, a plurality of slide rails 11 are provided on the lower connecting plate 1 near the first connecting tube 10. Each of the slide rails 11 is provided along the axis of the first connecting tube 10. A slider 310 is provided on the bottom surface of the support plate 31. The slider 310 can move in the slide rail 11 to limit the moving path of the support plate 31, thereby preventing the support plate 31 from being offset relative to the first connecting tube 10 when the stretch film is used to package the product.

[0026] In this embodiment, a plurality of protrusions 311 are evenly arranged on one side of the support plate 31 away from the first connecting tube 10, such as Figure 2 As shown, the protrusions 311 are evenly and vertically arranged. The protrusions 311 can increase the friction between the support plate 31 and the inner tube of the stretch film, thereby reducing the shaking of the stretch film relative to the support plate 31.

[0027] In this embodiment, a plurality of connecting holes 12 are provided near the edge of the lower connecting plate. The connection holes 12 are provided so that when the wrapping film fixing roller mechanism is directly placed on the rotating platform, in order to avoid shaking between the device and the rotating platform, the device can be directly fixed to the rotating platform by bolts.

[0028] In this embodiment, the support blocks are arranged in four groups, the telescopic plates 32 are arranged in four groups, and the spring group 30 includes four springs. One end of the spring is detachably connected to the outer surface of the first connecting tube 10, and the other end is fixed to the support plate 31.

[0029] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0030] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
