Description

Technical Field

[0001] This utility model belongs to the technical field of copper strip production equipment, and in particular relates to a surface treatment device for brass strip. Background Technology

[0002] During the production and processing of brass strips, their surfaces often become contaminated with oil, dust, impurities, and other pollutants. These contaminants not only affect the appearance quality of the brass strips but also adversely impact subsequent processing techniques such as coating and electroplating, reducing product performance and quality. Therefore, surface cleaning is a crucial step in the production of brass strips.

[0003] Existing brass strip surface cleaning devices have several problems. Firstly, they are ineffective at cleaning the brass strip surface, failing to thoroughly remove stubborn stains and minute impurities, resulting in unsatisfactory surface quality after cleaning. Secondly, the cleaning process is inefficient, unable to meet the demands of large-scale production, increasing production costs and time. These problems severely impact the efficiency and quality of actual brass strip production, hindering the development of related industries. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a brass strip surface treatment device, which can efficiently clean brass strips, improve the surface quality of brass strips and increase production efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a brass strip surface treatment device, comprising a cleaning chamber and a set of transmission rollers correspondingly arranged along the copper strip conveying direction. The cleaning chamber contains multiple cleaning rollers, which are symmetrically arranged vertically with their corresponding transmission rollers. A cleaning channel for the copper strip to pass through is provided between the cleaning rollers and the transmission rollers. Each cleaning roller includes a rotatable main shaft mounted within the cleaning chamber, a brush roller sleeved on the main shaft, and a cleaning brush mounted on the brush roller. One end of the main shaft extends outside the cleaning chamber and is connected to an external driving element. The main shaft is circumferentially... Multiple rows of elastic connectors are provided upwards to drive the brush roller to rotate. The brush roller is a hollow roller. One end of each elastic connector is fixed to the inner wall of the brush roller, and the other end is fixed to the outer wall of the main shaft. By optimizing the rigid roller into a multi-layered roller with elastic fit, the regular circular motion is transformed into axial eccentric swaying, increasing the cleaning coverage of a single rotation. At the same time, the swaying generates instantaneous contact pressure changes, similar to "pulse" cleaning, which can effectively break the oil stain adhesion layer, improve the cleaning efficiency of brass strips, improve production quality, and adapt to copper strips of different thicknesses to ensure the cleaning effect on copper strips of different thicknesses and specifications.

[0006] Preferably, the elastic connector can be a spring.

[0007] Preferably, the main shaft has multiple limiting grooves, and multiple limiting grooves are provided along the circumference of the main shaft. The inner wall of the brush roller has multiple driving platforms, and multiple driving platforms are provided along the circumference of the brush roller. Each driving platform is inserted into a corresponding limiting groove.

[0008] Preferably, when the main shaft and the brush roller are in any relative position, the drive platform is at least partially located within the limiting groove, and the width of the limiting groove is greater than the width of the drive platform.

[0009] Preferably, at least one buffer pad is provided on the outer wall of the main shaft and the inner wall of the brush roller, and at least one buffer pad is provided on the wall of the limiting groove and the driving platform.

[0010] Preferably, the cleaning brush is fixed to the brush roller, and the cleaning brush is arranged in a symmetrical spiral from the center of the brush roller to both ends, and as the brush roller rotates, its spiral direction is set from the center of the brush roller to the end direction.

[0011] Preferably, the cleaning brush includes a brush body and an elastic support member disposed on the brush body, the elastic support member being embedded within the brush body.

[0012] Preferably, the elastic support is a spring.

[0013] The technical effect of this utility model is as follows: by optimizing the rigid roller into a multi-layer roller with elastic fit, the regular circular motion is transformed into axial eccentric swaying, which increases the cleaning coverage of a single rotation. At the same time, the swaying generates instantaneous contact pressure changes, similar to "pulse" cleaning, which can effectively destroy the oil stain adhesion layer, improve the cleaning efficiency of brass strips, and improve production quality.

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] like Figures 1-5 As shown, a surface treatment device for brass strip includes a cleaning chamber 1 and a drive roller assembly. The cleaning chamber 1 is filled with a cleaning fluid, which is a commonly used cleaning fluid for copper strip cleaning. The drive roller assembly is prior art and includes a feed roller 11 and a discharge roller 12 located at the inlet and outlet of the cleaning chamber 1, and an intermediate guide roller 13 located between the feed roller 11 and the discharge roller 12. Four central guide rollers are arranged alternately in a staggered manner. Four cleaning rollers 2 are rotatably installed inside the cleaning chamber 1. The cleaning rollers 2 are arranged in a one-to-one correspondence with the intermediate guide rollers 13 and are symmetrically distributed on both sides of the copper strip conveying direction. A cleaning channel for the copper strip to pass through is provided between each pair of cleaning rollers 2 and intermediate guide rollers 13.

[0022] Specifically, the cleaning roller 2 is always immersed in the cleaning liquid. It includes a main shaft 21, a brush roller 22, and a cleaning brush 23. Both ends of the main shaft 21 are rotatably mounted on the walls of the cleaning chamber 1 via bearings, and one end of the main shaft 21 extends out of the cleaning chamber 1 and is connected to an external drive element. The drive element is existing technology and can be a separately installed drive motor that drives the main shaft 21 to rotate. The brush roller 22 is sleeved on the outer periphery of the main shaft 21, and a limiting groove 3 is formed on the outer wall of the main shaft 21. Multiple limiting grooves 3 are provided along the circumference of the main shaft 21. The limiting groove 3 is a long groove with closed ends. The brush roller 22 is a hollow shaft with a driving platform 4 on its inner wall. Multiple driving platforms 4 are provided along the circumference of the brush roller 22. Parts of the driving platform 4 are inserted into the corresponding limiting groove 3. The limiting groove 3 is provided with an elastic connector 5. The spring is a prior art spring, preferably made of alloy spring steel. The two ends of the elastic connector 5 are fixed to the bottom surface of the limiting groove 3 and the top surface of the driving platform 4, respectively.

[0023] Furthermore, when the main shaft 21 and the brush roller 22 are in any relative position, a portion of the driving platform 4 is located within the limiting groove 3, so as to ensure that the driving platform 4 can still drive the brush roller 22 to move even when the elastic connector 5 fails.

[0024] Furthermore, the outer wall of the main shaft 21, the inner wall of the brush roller 22, the wall of the limiting groove 3, and the drive platform 4 are all covered with rubber buffer pads to reduce the rigid impact between the brush roller 22 and the main shaft 21 and extend the service life of the cleaning roller 2.

[0025] Furthermore, the width of the limiting groove 3 is greater than the width of the driving platform 4, that is, the driving platform 4 may not directly contact any wall of the limiting groove 3 in the initial state. A movement gap is provided between the driving platform 4 and the limiting groove 3 to allow the driving platform 4 to move tangentially along the main body axis 21.

[0026] Furthermore, the cleaning brush 23 is fixed to the brush roller 22. The cleaning brush 23 is arranged in a symmetrical spiral from the center of the brush roller 22 to both ends. As the brush roller 22 rotates, its spiral direction is from the center of the brush roller 22 to the ends. The cleaning brush 23 includes a brush body 61 and an elastic support member 62. The elastic support member 62 is embedded in the brush body 61. The brush body 61 is made of plastic to ensure the cleaning effect on the copper strip while enhancing the toughness of the brush body and ensuring its service life.
