Description

Technical Field

[0001] The invention belongs to the technical field of tinned copper wire production, and particularly relates to a pretreatment device for tinned copper wire production and a use method thereof. Background Art

[0002] Tinned copper wire refers to copper wire with a thin layer of metallic tin plated on the surface. Tinned copper wire is relatively soft and has good conductivity. Compared with bare copper wire, it has stronger corrosion resistance and oxidation resistance, which can greatly extend the service life of low-voltage cables.

[0003] During the production of tinned copper wire, the copper wire needs to be cleaned and pre-treated before tinning to remove the attachments on the surface of the copper wire or the oil stains during the processing. However, the cleaning device can only remove part of the oil stains and impurities on the surface of the copper wire. For some stubborn oxides and tiny particles, the treatment effect is not good. For example, a simple spray cleaning method cannot clean deeply between the copper wire textures, resulting in poor adhesion and easy peeling of the subsequent tin plating layer.

[0004] Combining the above-mentioned problems, it is found that it is difficult to avoid the above-mentioned problems when the existing devices on the market are used, and thus it is impossible to achieve the desired effect. Therefore, we propose a pretreatment device for tinned copper wire production and a method of using the device, which can achieve deep pre-cleaning of copper wire during use to ensure that the subsequent tin plating adheres firmly. Summary of the invention

The brushing structure can wipe the copper wire while it is being transported in the cleaning chamber and the water washing chamber respectively, thereby achieving deep cleaning of the copper wire, thereby removing residual oxides and tiny particles on the surface of the copper wire, and rinsing the copper wire to remove residual cleaning agents on the surface of the copper wire, thereby ensuring the cleaning effect of the copper wire to the greatest extent.

[0047] like Figure 3 As shown, a thread groove 8 is provided on one side of the movable plate 735 close to the stud 734, and the stud 734 is threadedly connected to the inside of the thread groove 8, and a sealing structure is provided at the connection between the movable plate 735 and the rotating drum 72. By providing the thread groove 8, the threaded cooperation of the stud 734 and the movable plate 735 can be achieved, and by providing the sealing structure, the sealing between the rotating drum 72 and the movable plate 735 can be improved.

[0048] like Figure 4 As shown, the roller brush member 74 includes a fixed block 741, and two guide pillars 742 are bolted to one side of the fixed block 741 close to the movable plate 735, and the guide pillar 742 extends to the inside of the movable plate 735 on one side, and is in sliding contact with the movable plate.

The brush member 74 rotates together with the rotating drum 72, and utilizes friction to make the rotating brush wheel 744 rotate, so that the copper wire can be scrubbed by the flexible bristles arranged on the surface of the rotating brush wheel 744. When the rotating brush wheel 744 rotates to the bottom of the fixed cover 761, the separation thorns 764 on the surface of the jet tube 763 come into contact with the bristles of the rotating brush wheel 744, and the debris attached to its surface can be separated. The high-pressure gas is transported into the fixed cover 761 through the air inlet pipe 762, and distributed to multiple jet tubes 763 through the flow channel 765. The high-pressure gas is sprayed on the rotating brush wheel 744 through the jet tube 763 to purge the bristles. The high-speed airflow of the compressed air can blow away the impurities on the bristles and clean the rotating brush wheel 744.
