Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of foil processing, and relates to an anti-skid extrusion roller, a roller set and application. BACKGROUND

[0002] Foil refers to a metal sheet or strip with a thickness of less than 0.1 mm. Foil is usually prepared by rolling or other forming techniques, and is extremely thin. After special surface treatment, the foil has the characteristics of light weight, flexibility and wide application, and is widely used in the fields of electronics, aerospace, instruments and meters, etc.

[0003] The foil formed by repeated rolling of a strip is relatively low in roughness and smooth in surface due to the special processing process. In the process of subsequent surface treatment using an extrusion roller, the foil is prone to slipping due to the smooth surface of the foil. The slipping of the extrusion roller causes waste of electrolyte and scratching on one hand, and causes the roller set to be out of synchronization and further causes chemical corrosion marks and obvious appearance defects on the other hand, thereby resulting in double waste in on-site production. SUMMARY

[0015] The present application has the following beneficial effects: (1) The rubber coating layer is coated on the main roller body and the roller shaft, and the rubber coating layer forms an I-shaped flow guide ring at the connection between the main roller body and the roller shaft.

DETAILED DESCRIPTION

[0018] The technical solutions of the present application will be further explained and described through specific embodiments.

[0019] The embodiment of the present application provides an anti-slip squeeze roller, which is used for surface post-processing of smooth metal, such as surface post-processing of a calendered foil, etc. The anti-slip squeeze roller in the embodiment of the present application includes a main roller body 1 and roller shafts 2 located at both ends of the main roller body 1, as shown in FIGS. 1 and 2. Figure 1 、 2 ​

[0020] The main roller body 1 is a main component of the anti-skid squeeze roller, and the roller shaft 2 is fixed on both sides of the main roller body 1. The surfaces of the main roller body 1 and the roller shaft 2 are provided with the rubber coating 3, and the rubber coating 3 forms the I-shaped flow guide ring 4 at the connection between the main roller body 1 and the roller shaft 2.

[0021] When the solution on the foil is squeezed, the solution can be guided out to both ends of the main roller body 1 through the I-shaped flow guide ring 4, so as to prevent the solution from remaining on the surface of the main roller body 1 or eroding the gap of the rubber coating 3 from the surface. Therefore, the I-shaped flow guide ring 4 in the embodiment of the application can be used as a solution flow guide groove to prevent the solution from overflowing.

[0022] The connection between the main roller body 1 and the roller shaft 2 is wrapped, which can prevent the solution from penetrating between the main roller body 1 and the roller shaft 2 due to the possible gap, and further avoid the rubber coating 3 and the main roller body 1 or the rubber coating 3 and the roller shaft 2 from being delaminated.

[0023] In the application, the material of the rubber coating 3 is acid and alkali resistant rubber material, including one of ethylene-propylene-diene rubber, nitrile rubber and acrylate rubber. If the hardness of the rubber coating 3 is too low, it is relatively soft, and when it is in contact with the foil, it will increase the running resistance and scratch the foil. If the hardness of the rubber coating 3 is too high, it is relatively hard, and in the process of roller group extrusion, the fine lines of the grinding wheel will produce chemical corrosion marks, resulting in obvious appearance defects. Therefore, the Shore hardness of the rubber coating 3 in the embodiment of the application is D50-80.

[0024] In addition, the squeeze roller is used as a driven roller, and the power source is the movement of the foil. If the surface roughness of the rubber coating 3 is too low, that is, the surface is too smooth, the phenomenon of out of synchronization between the squeeze roller and the foil will occur. If the surface roughness of the rubber coating 3 is too high, the squeezing effect is not good, and the solution cannot be squeezed clean. Therefore, the surface roughness Ra of the rubber coating 3 in the embodiment of the application is 0.4-1.8 μm.

[0025] In order to avoid scratching or other damage to the surface of the foil during the squeezing process, the surface roughness Ra of the rubber coating 3 at the end surface of the main roller body 1 in the embodiment of the application is 1.2-1.8 μm, and the surface roughness Ra of the rest is 0.4-0.8 μm. For the area with the surface roughness Ra of 1.2-1.8 μm, the area is located at the end of the main roller body 1 and does not contact the foil, but contacts the driving roller. The surface roughness in this area is larger, which can improve the synchronization between the squeeze roller and the foil and the driving roller. For the area with the surface roughness Ra of 0.4-0.8 μm, the area is located at the middle part of the main roller body 1 and directly contacts the foil. The surface roughness in this area is smaller, which can avoid more solution remaining, and further avoid waste of solution and other defects.

[0026] Preferably, the length of the coating layer 3 with a surface roughness Ra of 1.2-1.8 μm on the upper surface of the main roller body 1 is 100 mm, that is, a coating layer 3 with a length of 100 mm and a surface roughness of 1.2-1.8 μm is provided on the upper surface of the main roller body 1. The length of this area can be specifically set according to the overall length of the roller assembly and the width of the foil.

[0027] In addition, the roller 2 in this embodiment is made of a high-strength acid and alkali resistant alloy, and its end is provided with a shaft head 5. The shaft head 5 is provided with a groove 6, which is used to position the main roller body 1, as shown in the attached figure. Figure 3 As shown.

[0028] This application embodiment also provides a roller assembly, which includes the aforementioned anti-slip squeezing roller 01 and drive roller 02, as shown in the attached figure. Figure 4 As shown, both the anti-slip squeezing roller 01 and the drive roller 02 have uniform cylindricity, and the cylindricity error is controlled within ±0.3mm. In addition, the runout value of the roller assembly is within the range of 0.05-0.10mm to ensure that the pressure during foil squeezing is always evenly distributed.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
