Description

Technical Field

[0001] This utility model relates to the field of battery equipment technology, specifically to a coating film smoothing roller and a coating machine. Background Technology

[0002] During the operation of a coating machine, the smoothing roller's function is to smooth the coating film as it wraps the product, preventing wrinkles, bubbles, and other defects, thus ensuring coating quality. However, existing smoothing rollers cannot flexibly adapt to coating films of different materials and thicknesses, as well as complex product shapes. Smoothing them can actually reduce coating quality and increase the defect rate. Utility Model Content

[0003] In order to overcome the defects in the prior art, this utility model provides a coating film smoothing roller and a coating machine, which can improve the coating quality of the coating film.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] The first aspect of this utility model discloses a film-coated smoothing roller, comprising:

[0006] A roller extending in a first direction;

[0007] A roller body is sleeved on the roller shaft, wherein a smoothing element is provided along the circumference of the roller body. When viewed from the axial direction of the roller body, the smoothing element is annular or two or more mutually disjointed arcs. The surfaces of the roller body and the smoothing element are coated.

[0008] The smoothing roller provided in this application, by providing smoothing elements circumferentially around the roller body, can apply pressure to the coating film during the smoothing process. This allows the smoothing roller to adhere more closely to the coating film upon contact, effectively smoothing and unfolding wrinkles and air bubbles in the coating film, thereby improving the coating quality. Furthermore, both the roller body and the smoothing elements are coated with a rough surface layer that allows for full contact with the coating film, increasing friction and preventing slippage between the roller body and the coating film during smoothing. This also avoids damage to the coating film, ensuring a smooth coating process.

[0009] Furthermore, the smoothing component is a protrusion formed by extending from the end face of the roller body away from the roller shaft in a direction away from the roller body, and the protrusion is integrally formed with the roller body. The smoothing component provided in this application is not only simple in structure but also easy to manufacture, which can avoid the problems of loosening or falling off that exist in traditional smoothing components, and further improve the smoothing effect.

[0010] Furthermore, the number of smoothing elements is multiple, and the multiple smoothing elements are spaced apart along the first direction. This allows the smoothing elements to make more comprehensive contact with the coating film, ensuring that the coating film is subjected to uniform and continuous pressure during the smoothing process, and avoiding any areas that are not smoothed.

[0011] Furthermore, in the first direction, the smoothing element is positioned close to the center of the roller. Because the smoothing element is close to the center of the roller, the force generated during the smoothing process is more concentrated, which can better eliminate wrinkles and bubbles on the coating film, improving smoothing efficiency and quality.

[0012] Furthermore, the height of the smoothing component protruding from the roller surface is 1-3 mm. This ensures that when the smoothing component contacts the coating film, it can apply sufficient pressure to achieve a smoothing effect without damaging the coating film surface due to excessive pressure.

[0013] Furthermore, the roller body has a shape that includes one of cylindrical, conical, or frustum shapes, and its length is greater than the width of the coating film to be smoothed. This ensures that the roller body can fully cover and smooth the coating film, improving smoothing efficiency and quality.

[0014] Furthermore, the coating is made of nanocomposite material. Nanocomposite material has excellent wear resistance and corrosion resistance, which can effectively extend the service life of the smoothing part. The microstructure of nanocomposite material can increase the friction between it and the coating film, ensuring that the film is not damaged during smoothing and coating, and effectively preventing the film from sliding on the roller and causing wrinkles.

[0015] Furthermore, the roller shaft includes a first fixing part and a second fixing part, which are respectively located at both ends of the roller body and spaced apart from the roller body. The first fixing part and the second fixing part are used to fix the roller shaft to other structures, so that the roller body can be stably supported at both ends, ensuring its stability when smoothing the coating film.

[0016] The second aspect of this utility model discloses a coating machine, which includes the coating film smoothing roller described in any one of the first aspects.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] 1. This application provides a smoothing component in the circumferential direction of the roller body, which can apply pressure to the coating film during the smoothing process, so that the smoothing roller can fit more closely when it comes into contact with the coating film, thereby effectively smoothing and unfolding the wrinkles and air bubbles of the coating film and improving the coating quality.

[0019] 2. This application applies a coating to the surfaces of the roller and the smoothing component. The coating surface is rough and can fully contact the coating film, increasing friction and preventing slippage between the roller and the coating film during the smoothing process. At the same time, it avoids damage to the coating film and ensures the smooth progress of the coating process.

[0029] Reference Figures 1-2 This application provides a film-coated smoothing roller, including a roller shaft 1 extending along a first direction and a roller body 2 sleeved on the roller shaft 1, wherein a smoothing element 3 is provided along the circumference of the roller body 2, and the surfaces of the roller body 2 and the smoothing element 3 are coated.

[0030] With the above structure, the smoothing roller of this application embodiment can fit the coating film more closely during smoothing, thereby smoothing and unfolding the wrinkles on the coating film, improving the coating quality of the coating film. In addition, during the smoothing process, the surface of the smoothing roller is rough, which can fully contact the coating film, increase the friction, prevent the smoothing roller from sliding between the coating film during the smoothing process, and avoid damage to the coating film.

[0031] Specifically, in this embodiment, the roller 1 is cylindrical in shape, with both ends of the roller 1 extending outside the roller body 2. The roller 1 includes a first fixing part 4 and a second fixing part 5, which are located at the two ends of the roller body 2 and are spaced apart from the roller body 2.

[0032] The shape of the roller 2 can be flexibly set. In some embodiments, the shape of the roller 2 is one of cylindrical, conical, or frustum-shaped.

[0033] In this embodiment, the roller body 2 is generally circular and is sleeved on the cylindrical roller shaft 1. The roller body 2 and the roller shaft 1 extend in the same direction, and the length of its extension is greater than the width of the coating film to be smoothed, so as to ensure that the roller body 2 can fully cover and smooth the coating film.

[0034] In this embodiment, the smoothing element 3 is a protrusion formed by the roller body 2 extending from the end face away from the roller shaft 1 in a direction away from the roller shaft 1, and the protrusion is integrally formed with the roller body 2. Optionally, the height of the smoothing element 3 protruding from the surface of the roller body 2 is 1 to 3 mm.

[0035] Viewed from the axial direction of the roller body 2, in some embodiments, the smoothing element 3 is annular in shape, so that the smoothing element 3 is evenly distributed in the circumferential direction of the roller body 2. This ensures uniform force when smoothing the film material, avoids wrinkles or bubbles, and thus provides a better smoothing effect. Furthermore, its manufacturing is relatively simple. Figure 2 As shown. In other embodiments, the smoothing element 3 is formed by two or more mutually disjointed arcs, so that the length, spacing, and other parameters of each arc can be adjusted according to actual needs to adapt to coating films of different specifications or materials, such as... Figure 3 As shown.

[0036] The smoothing member 3 extends along the first direction, and its extension length can be flexibly set according to the actual situation. In some embodiments, a smoothing member 3 is provided on the roller body 2, and in the first direction, the smoothing member 3 is provided near the middle of the roller body 2.

[0037] In some embodiments, a plurality of smoothing members 3 are provided, and the plurality of smoothing members 3 are all in the form of a continuous ring, and the plurality of ring smoothing members 3 are spaced apart along a first direction.

[0038] In some embodiments, the coating on the surface of the smoothing roller is made of a wear-resistant, non-slip material to increase the friction between the smoothing roller and the coating film. Optionally, the coating is made of a nanocomposite material.

[0039] The materials of the roller 1, roller body 2 and smoothing component 3 in the embodiments of this application can be flexibly set, such as metal or plastic, and this application does not make specific limitations.
