DETAILED DESCRIPTION

[0021] A device for smoothing cable conductors, see Figure 1-Figure 4 , which includes a box body 10, two groups of brush assemblies 20, and at least two groups of compressed gas inlet pipes 30:

[0022] The box body 10 includes a box body 40 and a cover plate 50. The cover plate 50 is installed on the upper part of the box body 40. The cover plate 50 is connected to a long side of the upper part of the box body 40 through a flip hinge 51. The upper center areas of the two end plates 41 of the box body 40 are respectively provided with conductor entry and exit notches. In specific implementation, the conductor entry and exit notches of the left end plate are conductor entry openings 42, and the conductor entry and exit notches of the right end plate are to conductor exit openings 43. The corresponding conductor 60 passes through the box body 40 along the conductor entry openings 42 and the conductor exit openings 43.

[0023] Each set of brush assemblies 20 includes an upper brush 21 and a lower brush 22, and the upper brush 21 and the lower brush 22 are respectively mounted on corresponding mounting shafts 23. Each set of mounting shafts 23 is fixed to corresponding positions of the side panels 44 of the box body 40 through brackets 24 on both sides. The brackets 24 are provided with vertical waist-shaped grooves 241 at positions corresponding to each mounting shaft 23. Each mounting shaft 23 is mounted with a bearing 25 and then embedded in the corresponding vertical waist-shaped groove 241. The corresponding input end of each mounting shaft 23 is respectively connected to the corresponding brush rotating motor 70 through the power transmission mechanism 120, and each brush rotating motor 70 drives a set of brush assemblies 20 to rotate.

[0024] A plurality of air inlets 411 are provided on the end plate 41 of the box body 40 corresponding to the conductor inlet 42. The compressed air inlet pipe 30 is provided through the air inlet 411. The compressed air inlet pipe 30 blows toward the surface of the conductor 60 to blow off the debris on the surface of the conductor 60.

[0025] A group of brush assemblies 20 are arranged on both sides of the guide conveying channel between the conductor inlet 42 and the conductor outlet 43 of the box body 40. The upper brush 21 and the lower brush 22 of each group of brush assemblies 20 are arranged to fit the outer edge of the conductor 60. The brush assembly 20 is arranged behind the linear movement of the conductor in the outlet area of ​​the compressed gas inlet pipe 30.

[0026] In a specific embodiment, a drawer-type recovery slot 80 is also included. A drawer notch 45 is provided at the bottom of one side panel of the box body 40. The drawer-type recovery slot 80 is inserted into the bottom of the box body 40 through the drawer notch 45. The surface area of ​​the exposed panel 81 of the drawer-type recovery slot 80 is larger than the drawer notch. The upper part of the exposed panel 81 is a handle edge 811, which is convenient for pulling out the drawer-type recovery slot 80.

[0027] The drawer-type recycling slot 80 is also provided with a cover plate 90. After the drawer-type recycling slot 80 is pulled out of the box body 40, the cover plate 90 is covered on the upper surface of the drawer-type recycling slot 80 so that the debris will not be scattered to the side area.

[0028] A vibration motor 100 is arranged below the lower brush 22 of each group of the brush assembly 20, and the base of the vibration motor 100 is fixedly arranged on the bottom plate of the box body 10, and the upper vibration output end of the vibration motor 100 drives the lower brush 22 to vibrate, and the upper surface of the lower brush 22 is attached to the lower surface of the upper brush 21, so that the brush assembly 20 vibrates, and the resonance generated by the vibration motor 100 is in the same frequency as the conductor, and the surface of the conductor 60 is cleaned twice; the vibration of the vibration motor 100 is a micro-amplitude vibration, and the vibration motor 100 is located directly below the center position of the length direction area of ​​the lower brush 21, which will not affect the transmission of the power transmission mechanism 120, and the design of the vertical waist-shaped groove 241 makes it possible to reliably buffer even if the mounting shaft 23 vibrates in the height direction;

[0029] In specific implementation, the power transmission mechanism 120 includes a group of transmission gears and a group of synchronous pulleys. The input end of the mounting shaft corresponding to the upper brush 21 is provided with an input pulley 123 and an output gear 121. The mounting shaft sleeve corresponding to the lower brush 22 is provided with an input gear 122. The output shaft of the brush rotating motor 70 is connected to the input pulley 123 through an output pulley 124 and a synchronous belt 125. The output gear 121 is meshed and connected to the input gear 122. When the brush assembly 20 vibrates slightly, the synchronous belt 125 has elastic adjustment capabilities to ensure stable and reliable transmission of the synchronous pulleys. After the output gear 121 and the input gear 122 are meshed and connected, they can resist the slight vibration of the brush assembly 20 and will not affect the reliable operation of the power transmission mechanism 120.

[0030] The transmission gear makes the upper brush and the lower brush roll in opposite directions. The upper brush 21 and the lower brush 22 of each brush assembly 20 are provided with a scraper 110 at a position close to the box body 40. The scraper 110 scrapes foreign matter off the brush and drops it into the drawer-type recovery tank 80 below.

[0031] In a specific implementation, the cover plate 50 in the working state is installed on the box body 40. After the conductor 60 enters the box body 40, it first passes through the compressed gas inlet pipe 30 to blow away foreign matter on the surface. The compressed gas inlet pipe 30 only blows pressure on the surface of the conductor 60 in the covered area, and will not cause large-scale airflow disturbance to the rest of the box body 40. Then the conductor 60 moves in a straight line along the length direction of the box body 10. The upper brush 21 and the lower brush 22 of each group of brush assemblies 20 are arranged to fit through the outer edge of the conductor 60. The brush 21 The copper powder in the gaps on the surface of the conductor, the copper chips and burrs on the surface are scraped off from the surface of the conductor, and the resonance generated by the vibration motor 100 is in the same frequency as the conductor, so as to smooth the surface of the conductor for a second time. At the same time, the brush uses the scraper 110 provided by the equipment on the rear side of the rotation to shake off the foreign matter transferred from the conductor 60 to the brush into the drawer-type recovery tank 80, and the drawer-type recovery tank 80 is used to collect the residue. Finally, the conductor 60 with the surface cleaned is separated from the box body 40, ensuring that the foreign matter on the surface of the conductor is reliably cleaned, thereby ensuring the reliable performance of the cable after production.
