Description

TECHNICAL FIELD

[0001] The application relates to the technical field of copper-aluminum composite strip production equipment, in particular to a damping device for a copper-aluminum composite strip cleaning line. BACKGROUND

[0002] During the manufacturing process of copper-aluminum composite strips, cleaning and drying steps are required. The cleaning step is to remove impurities, oil stains and oxide layers on the copper and aluminum strips. These contaminants can affect the interfacial bonding strength of the composite material, thereby affecting the performance of the final product. Through cleaning, the surfaces of the two metals can be ensured to be cleaner, which is beneficial to the formation of good metallurgical bonding during subsequent rolling or bonding processes. This is crucial for improving the electrical conductivity, thermal conductivity and mechanical strength of the copper-aluminum composite strip. The drying step can remove residual moisture after cleaning, preventing corrosion or oxidation of the material during storage or transportation. This is very important for maintaining the long-term stability and reliability of the material.

[0003] When the copper-aluminum composite strip is cleaned and dried, the strip may vibrate under external force. When the vibration is too large, it may cause the strip to form vibration marks, wrinkles, or even deviation. This phenomenon is particularly evident when the strip thickness is thin. Therefore, a damping device is needed to eliminate the vibration of the strip and ensure stable operation of the strip. At the same time, the damping device needs to be in contact with the surface of the strip. If particles adhere to the surface of the damping device, it may cause scratches on the surface of the strip, affecting the final quality of the copper-aluminum composite strip.

The flexible negative pressure pipe is connected to an external air suction pump. An electric control telescopic rod is installed on the outer side of the upper end of the negative pressure suction nozzle.

[0022] The three rollers are arranged in a "pin" shape, the strip 7 passes through the middle, the rollers at both ends are fixed rollers 1, and the roller in the middle is a floating roller 2. The spring 5 is arranged between the sliding block 6 and the top cover 4, and the strip 7 relies on the spring force to slow down the vibration when passing through, thereby stabilizing the strip.

[0023] When the strip 7 passes through the damping device, the upward pressure generated by the vibration of the strip 7 is transmitted to the intermediate floating roller 2; the floating roller 2 drives the sliding block 6 to move up and down along the sliding groove 3, and due to the presence of the spring 5, the force acting on the roller by the vibration of the strip 7 is transmitted to the spring 5, and the counterforce generated by the spring 5 acts on the strip 7 to offset the vibration of the strip.

[0024] The spring force of the spring 5 can be adaptively adjusted according to the vibration degree of the strip, that is, when the vibration of the strip 7 is larger, the spring force of the spring 5 is also larger; when the vibration of the strip 7 is smaller, the spring force of the spring 5 is also smaller.

[0037] The air suction pump is started synchronously, the air inlet of the negative pressure suction nozzle 14 is sucked into a negative pressure state through the flexible negative pressure pipe 13, so that the solid particles adhering to the outer surface of the floating roller 2 are sucked away by the negative pressure suction nozzle 14, the electric control telescopic rod 12 is extended in time to press the shovel plate 11 against the stains on the outer surface of the floating roller 2, and the removed stain particles are finally sucked away by the negative pressure suction nozzle 14.
