Technical Field

[0002] Polyethylene is a thermoplastic resin obtained by polymerizing ethylene monomers. Industrially, it also includes copolymers of ethylene with small amounts of α-olefins. Polyethylene is odorless, non-toxic, and has a waxy feel. It has excellent low-temperature resistance and good chemical stability. Because the polymer molecules are linked by carbon-carbon single bonds, it can resist the erosion of most acids and alkalis. It is insoluble in common solvents at room temperature, has low water absorption, and excellent electrical insulation. Polyethylene is very sensitive to environmental stress and can be processed using general thermoplastic molding methods. Polyethylene has a wide range of uses, mainly used to manufacture films, packaging materials, containers, pipes, monofilaments, wires and cables, daily necessities, etc. It can also be used as a high-frequency insulating material for televisions, radar, etc. Polyethylene foaming is a processing technology that uses physical or chemical methods to form a honeycomb structure inside the material, and it is widely used in packaging, construction, automobiles and other fields.
[0003] Existing polyethylene foam materials are usually produced by continuous winding. However, the residual heat in polyethylene during the foaming process is not fully dissipated, and continuous winding may cause heat accumulation. The wound material is prone to sticking or deformation. Therefore, an intermittent winding device for polyethylene foam rolls is needed to meet people's needs. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-5 An intermittent winding device for polyethylene foam roll material includes a base 1 and a roll material 2. A first column 3 is provided on the base 1. A servo motor 4 and a controller 5 are provided on one side of the first column 3. The servo motor 4 and the controller 5 are connected by an electrical signal. An air expansion shaft 6 is provided on the output shaft of the servo motor 4. The air expansion shaft 6 is arranged on the side of the first column 3 away from the servo motor 4. Two second columns 7 are provided on the base 1. A first air duct 8 and a second air duct 9 are provided between the two second columns 7. Air holes 10 are opened at the bottom end of the first air duct 8 and the top end of the second air duct 9.

A connecting pipe 12 is provided at the air outlet of the fan 11. The connecting pipe 12 is connected to the first air duct 8 and the second air duct 9.
[0022] Through precise programming and parameter setting of controller 5, servo motor 4 drives air shaft 6 to perform intermittent circular motion, thereby achieving intermittent winding effect of polyethylene foam roll material. This allows the polyethylene foam roll material to pause regularly during the winding process, which helps dissipate heat and prevents the material from sticking or deforming. Through the setting of fan 11, connecting pipe 12, first air duct 8, second air duct 9 and air hole 10, heat dissipation is achieved before the polyethylene foam roll material is wound on air shaft 6, further preventing the material from sticking or deforming. At the same time, it can remove dust adsorbed on the surface of the material.

The slide rod 14 is arranged below the air shaft 6, and a roller 15 is rotatably connected to the slide rod 14. The roller 15 is arranged parallel to the air shaft 6, so that when the air shaft 6 intermittently winds up the roll 2 and stops, the elastic force of the spring 13 acts on the slide rod 14, so that the roller 15 presses against the bottom of the roll 2 to prevent the roll 2 from loosening when it stops.
[0024] Specifically, in this embodiment, a sliding groove 16 is provided on the first column 3. The sliding groove 16 is arranged vertically. The spring 13 is connected to the bottom end of the sliding groove 16. One end of the sliding rod 14 is slidably adapted in the sliding groove 16 to provide vertical guidance for the movement of the sliding rod 14.
[0025] Specifically, in this embodiment, a connecting rod 17 is provided between the top and bottom ends of the slide groove 16, and one end of the slide rod 14 located in the slide groove 16 is slidably connected to the connecting rod 17, thereby improving the stability of the slide rod 14 and the overall performance of the connection between it and the slide groove 16.
[0026] Specifically, in this embodiment, the slide bar 14 is provided with two ear plates 18, and the roller 15 is rotatably connected between the two ear plates 18 to provide rotational support for the roller 15.
[0027] Specifically, in this embodiment, a first guide roller 19 and a second guide roller 20 are rotatably connected between the two second columns 7. The first guide roller 19 and the second guide roller 20 are both arranged between the first air duct 8 and the second air duct 9. The roll material 2 is arranged in an S-shape on the first guide roller 19 and the second guide roller 20, which increases the travel distance of the roll material 2 during the winding process, thereby increasing the heat dissipation time and improving the heat dissipation efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
