Description

Technical Field

[0001] This utility model relates to the field of stretch film technology, specifically to a stretch film roll and a stretch film. Background Technology

[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 a plasticizer that also acts as a self-adhesive. Stretch film is a plastic film widely used in industrial and commercial packaging. It can tightly wrap around goods or pallets, providing a packaging solution that is moisture-proof, dust-proof, reduces labor, improves efficiency, and lowers costs. Stretch film needs to be wound up in rolls.

[0003] Existing patent: CN217675963U, a roll for stretch film and stretch film, including a roll and an adjusting frame. The adjusting frame is installed at both ends of the roll. 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. A slit is opened between the upper cutter and the lower cutter. Stretch film is inserted through the slit.

[0004] The aforementioned patents or existing rolls and stretch films have the following problems:

[0005] When winding up stretch film on existing rolls, one end of the stretch film needs to be fixed to the roll. However, existing stretch film is not easy to fix to the roll, which leads to the problem of slippage during winding. Utility Model Content

[0006] The purpose of this invention is to provide a roll for stretch film and a stretch film to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a winding roll for stretch film and a stretch film, comprising a winding roll, wherein a film body is wound on the surface of the winding roll, and a film clamping structure is provided on the surface of the winding roll, the film clamping structure comprising a clamping groove, the clamping groove being provided on the surface of the winding roll, a clamping slot being provided inside the winding roll, a press-and-rebound device being assembled in the clamping slot, a clamping plate being assembled on the clamping groove, and a clamping block being provided at one end of the clamping plate, the clamping block being connectable to the press-and-rebound device.

[0008] Preferably, the inside of the winding drum is provided with a limiting port, and the surface of the clamping plate is provided with a limiting block.

[0009] Preferably, when the card plate is assembled in the card slot, the surface of the card plate and the surface of the take-up drum are on the same arc surface.

[0010] Preferably, one end of the slot is extended to the surface of the take-up drum.

[0011] Preferably, the inner surface of the card plate is provided with pressure teeth, which are in the shape of horizontal strips.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Place one end of the membrane body into the slot, then press the card plate into the slot, thus pressing it onto the surface of the membrane body. At this time, the limiting block will be inserted into the limiting hole to achieve the correspondence between the card block and the card hole. Then slide the card plate so that the card block slides into the card hole and connects with the pressing and rebounding device, thereby fixing the card plate in the slot and pressing and limiting the membrane body in the slot. At the same time, the limiting block will be locked in the limiting hole to limit the position, so as to achieve the beneficial effect of conveniently fixing one end of the membrane body onto the winding drum.

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1 and Figure 2 This utility model provides a winding roll and winding film for stretch film, including a winding roll 1, a film body 2 wrapped on the surface of the winding roll 1, the film body 2 being the stretch film, and a film clamping structure 3 provided on the surface of the winding roll 1.

[0021] Please see Figure 2 , Figure 3 and Figure 4This utility model provides a winding roll and winding film for stretch film. The film clamping structure 3 includes a clamping groove 31. The surface of the winding roll 1 is provided with the clamping groove 31. One end of the clamping groove 31 is extended and extends to the surface of the winding roll 1 to avoid scratching the film body 2. The inside of the winding roll 1 is provided with a clamping slot 32. A press-rebound device 33 is installed in the clamping slot 32. A clamping plate 34 is installed on the clamping groove 31. One end of the clamping plate 34 is provided with a clamping block 35. The clamping block 35 can be connected to the press-rebound device 33.
