Description

Technical Field

[0001] This utility model relates to the field of packaging-related technology, and in particular to a winding roll for wrapping stretch film and a stretch film. Background Technology

[0002] Stretch film, also known as stretch film or heat shrink film, primarily provides surface protection for products, forming a lightweight, protective outer layer around the product to achieve dustproof, oilproof, moisture-proof, waterproof, and theft-proof purposes. Traditional stretch film rolls are relatively simple, and due to the adhesive nature of the film, it tends to adhere to the next layer after use, making it difficult to find for future use. Furthermore, since the film is continuous, it is often difficult to tear after use, or the tears are uneven, causing inconvenience for subsequent use. Additionally, the stretch film roll cannot rotate, making it inflexible in use.

[0003] To address this issue, patent document CN217675963U discloses a stretch film roll and stretch film, comprising a roll and adjusting frames. Adjusting frames are installed at both ends of the roll, and an upper cutter is movably installed at the top between the two sets of adjusting frames. A lower cutter is fixedly installed below the upper cutter, and a slit is formed between the upper and lower cutters, through which the stretch film passes. This technical solution solves the problems of stretch film rolls being relatively simple, and due to the adhesive nature of the stretch film, it adheres to the next layer after use, making it difficult to find for future use. Furthermore, the stretch film is continuous, making it difficult to tear after use, or resulting in uneven tears, causing inconvenience for future use. Additionally, the stretch film roll cannot rotate, making it inflexible in use.

[0004] The aforementioned stretch film winding roll and stretch film have several shortcomings in use. First, the roll lacks rolling support, making it difficult to easily remove in situations requiring large quantities of stretch film. Second, after the cutter in the roll's adjusting frame cuts the stretch film, some adhesive residue remains, which can easily cause deformation of the cut during pulling, leading to inconvenience for subsequent uses. Therefore, optimization and improvement are necessary. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned problems existing in the traditional technology and to provide a winding roll and winding film for winding film.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] This utility model provides a winding roll for wrapping film, including a roll component, a bottom support, a friction block, a side support support, and a film cutting component;

[0008] The base support includes a rectangular frame, with a groove on one long side of the rectangular frame to facilitate the sliding of the film cutting component, and through holes symmetrically provided on the two short sides of the rectangular frame;

[0009] There are two friction blocks, which are symmetrically installed at both ends of the base bracket. Each friction block includes a friction block body. Two damping telescopic rods are embedded inside the friction block body. The outer ends of the damping telescopic rods can pass through the through holes and are connected to a side support bracket for providing rolling internal support for the drum component.

[0010] Furthermore, in the aforementioned winding roll for wrapping the film, the bottom end face of the friction block body is provided with an anti-slip rough surface.

[0011] Furthermore, in the aforementioned winding roll for stretch film, the side support bracket includes a side support base, a rotating block, a handle, a rolling support member, and a locking screw. The side support base has a circular cavity inside to facilitate the movement of the rotating block. One side of the rotating block is fixed with a handle that passes through the side support base. The other side of the rotating block has several arc-shaped push grooves along the circumference. The inner side of the side support base has several radial sliding grooves along the circumference. The arc-shaped push grooves and the corresponding radial sliding grooves together restrict the rolling support member. The outer side of the side support base has a rotating hole inward to facilitate the movement of the handle. The top of the side support base has a locking screw hole inward to cooperate with the locking screw.

[0012] Furthermore, in the aforementioned winding roll for stretch film, the rolling support is composed of a slide rod, a slide head, and a rolling sleeve. The slide rod slides and is restricted in a corresponding radial groove. One end of the slide rod is fixed with a slide head that slides and is restricted in a corresponding arc-shaped push groove. The other end of the slide rod is fitted with a movable rolling sleeve.

[0013] Furthermore, in the aforementioned winding roll for the stretch film, the outer side of the slide rod has a positioning protrusion to prevent axial displacement, and the inner cavity of the rolling sleeve has a positioning ring groove that mates with the positioning protrusion.

[0014] Furthermore, in the aforementioned winding roll for the stretch film, the side support is provided with a storage groove for facilitating the storage of the film cutting component, and the position of the storage groove is matched with the position of the cutting groove in the bottom support.

[0015] Furthermore, in the above-mentioned winding roll for stretch film, the film cutting component consists of a mounting block, a pull ring, a double-sided cutter, and a roller. The mounting block has a pull ring on its side end, a double-sided cutter is mounted on the lower end of the mounting block, a roller is mounted on the bottom end of the double-sided cutter, the upper end of the double-sided cutter is 2-3 mm higher than the upper end of the cutting groove, and the roller can roll along the bottom end of the cutting groove.

[0016] This utility model also provides a winding film, which uses the winding component in the winding roll of the above-mentioned winding film as the winding object.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a winding roll and winding film for stretch film winding. The roll mainly consists of a roll component, a base support, a friction block, a side support support, and a film cutting component. The components work together. When it is necessary to replace the stretch film and the roll component, at least one side support support is slowly moved outward. After the roll component is inserted, the moved side support support is reset. The side support support uses multiple rolling support members to provide rolling support for the roll component. The position of the rolling support members can be pre-adjusted according to the inner diameter of the roll component to meet the rolling support requirements of roll components of different specifications, especially in situations where a large amount of stretch film is used. When it is necessary to cut the stretch film, the film cutting component can be slid along the cutting groove, which is convenient to operate.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description
