[0025] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0026] This technical solution combines antistatic materials with humidity control technology to effectively prevent static electricity buildup, ensure a smooth coating process, and improve the ease of operation and compatibility of the equipment.

[0027] like Figures 1 to 4 As shown, this application provides a film antistatic auxiliary device for a box packaging moisture-proof machine, including an antistatic roller 3, a hydrogel cavity 201, and an installation assembly.

[0028] The antistatic roller of this application is made of high-performance antistatic fiber material with low surface resistivity, which can quickly dissipate static electricity generated by film friction. In this embodiment, the diameter and length of the antistatic roller can be determined according to the model of the coating machine. Typically, the diameter of the antistatic roller ranges from 20 to 50 mm, and its length matches the width of the film. Furthermore, in this application, the antistatic roller includes an antistatic roller body and a wear-resistant coating disposed on the outer surface of the antistatic roller body, enhancing its durability and extending the replacement cycle.

[0029] In this application, the two ends of the antistatic roller 3 are connected to the mounting assembly via a connecting shaft 403 and bearings, respectively. High-precision bearings are used to ensure that it can rotate adaptively when the film moves, thereby reducing resistance.

[0030] In this application, a moisturizing hydrogel is disposed within the hydrogel cavity 201, and moisturizing holes 204 are provided on the hydrogel cavity 201. The hydrogel cavity is snap-fitted into the mounting component. The moisturizing hydrogel is made of a highly absorbent polymer, which can maintain stable moisture release for a long time and avoid the generation of flowing liquid that would affect the drying properties of the film.

[0031] The mounting assembly is installed on the film holding roller of the coating machine.

[0032] In this application, the mounting assembly includes a cavity shell 1, a sleeve shell 2, and a mounting base 4. The sleeve shell 2 is provided with a hydrogel cavity 201, a mounting base shell 202, and an antistatic roller shell 205. The mounting base shell 202 is located at both ends of the hydrogel cavity, and the cavity shell 1 is located above the hydrogel cavity 201 to seal the hydrogel cavity. The hydrogel cavity and the cavity shell are connected by snap-fit ​​connections to form a sealed space for storing moisturizing hydrogel.

[0033] An antistatic roller shell 205 extends downwards on both sides of the hydrogel cavity 201, forming an opening at the bottom of the hydrogel cavity. Multiple moisturizing holes 204, with a pore size of 0.5-1 mm, are evenly distributed on the bottom surface of the hydrogel cavity to ensure uniform humidity release. Figure 4 As shown, the antistatic roller shell 205 and the antistatic roller 3 form a semi-enclosed space 5, which is connected to the moisturizing hole 204, so that a stable micro-humid environment is formed around the film, and the humidity is controlled between 40% and 60%, which significantly reduces the risk of static electricity accumulation.

[0034] A latch 203 is provided below the mounting housing 202, which engages with the mounting base 4. The mounting base includes a mounting base body, a slot 401 is provided below the mounting base body, a set screw threaded hole 402 is provided above the mounting base, and a connecting shaft 403 is provided on the inner surface of the mounting base body. The slot 401 of this application has an arc-shaped design, which matches the outer diameter of the film fixing roller of the coating machine. During installation, it is only necessary to align the slot with the fixing roller and slide it in. The top of the mounting base has a set screw threaded hole, which can be fixed by screwing in the set screw. It also supports fine adjustment of the contact distance between the antistatic roller and the film, with an adjustment range of 0-5 mm, to adapt to films of different thicknesses and tensions. The connecting shaft is made of stainless steel, which is corrosion-resistant and has high strength, ensuring stability under long-term use.

[0035] During use, the film is drawn from the fixed roller of the coating machine. As it passes through the antistatic roller, the static electricity generated by friction on the roller surface dissipates. At the same time, the moisturizing hydrogel in the hydrogel cavity releases moisture through the moisturizing holes, regulating the environment around the film and preventing additional static electricity caused by dryness. The antistatic roller and the hydrogel cavity work together to form a dual antistatic mechanism, ensuring the smoothness of the film during high-speed extraction and coating.

[0036] This device is easy to install; simply insert the mounting bracket into the film fixing roller of the coating machine, adjust the angle and height, and then tighten the set screw. For maintenance, it is recommended to check the wear of the antistatic roller every 3-6 months. If the surface fiber layer becomes thinner or the static dissipation effect decreases, replace the roller. The hydrogel should be replenished or replaced every 6-12 months depending on its humidity regulation effect to ensure long-term stable operation.

[0037] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
