Description

Technical Field

[0001] The utility model relates to the field of cable processing, in particular to a cable cleaning device. Background Art

[0002] The core of the cable is mainly composed of copper wire. The core needs to be cleaned during cable production. A Chinese patent application document with publication number CN117123639A discloses a copper wire cleaning device, which includes a machine platform, on which a conveying roller capable of pressing and guiding the conveying core is arranged, and a soaking cylinder for the core to pass through and a first cleaning component for inputting cleaning liquid into the soaking cylinder to clean the copper powder or impurities remaining on the surface of the core. A cleaning cylinder is arranged between the conveying roller and the soaking cylinder, and a brush, a scraper and a second cleaning component capable of spraying cleaning liquid are fixedly arranged in the cleaning cylinder. When the conveying roller drives the core to move, the brush and the scraper can abut against the core and scrape off the copper powder or impurities attached to the core, and then the second cleaning component rinses off the scraped residue on the surface of the core.

[0003] In the process of producing cables, generally only newly produced wire cores will have residual copper powder or impurities. These are residues attached to the surface of the wire core and can be scraped off by brushes and scrapers, so they have a better cleaning effect. The existing cable production also recycles the waste wire cores removed from the used cables for new production. The waste wire cores may be aged after long-term use, and an oxide layer will form on their surface. The oxide layer is part of the wire core rather than an attachment. Therefore, the oxide layer on the surface of the waste wire core cannot be removed by using a brush and a scraper. An additional deoxidation treatment step is required to prevent the oxide layer from affecting the conductivity of the wire core. Therefore, there is still room for improvement in the existing cable cleaning device. Utility Model Content

[0004] In view of the shortcoming that the existing cable cleaning device cannot remove the oxide layer produced on the surface of the waste wire core, the purpose of the utility model is to provide a cable cleaning device that can effectively remove the oxide layer on the surface of the wire core and then clean the wire core.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A cable cleaning device comprises a machine platform and a cleaning mechanism arranged on the machine platform, wherein the machine platform is provided with a conveying roller group for conveying the core to the cleaning mechanism, and the machine platform is provided with a grinding mechanism for grinding the outer wall of the core during the conveying process.

[0007] The above scheme is adopted. In this scheme, when the conveying roller group is conveying the wire core, the grinding mechanism can remove the oxide layer on the surface of the wire core as much as possible by rubbing the surface of the wire core, thereby reducing the influence of the oxide layer on the conductivity of the wire core. The wire core after grinding will be conveyed to the cleaning mechanism to clean up the grinding debris remaining on the wire core. Compared with the prior art, the cable cleaning device in this scheme can effectively remove the oxide layer formed on the surface of the waste wire core, so that the wire core can be recycled normally, and the process of removing the oxide layer and the process of cleaning the wire core are seamlessly connected on the same assembly line, eliminating the need for an additional deoxidation treatment step, thereby effectively improving production efficiency.

[0008] Preferably, the grinding mechanism includes a retaining component fixed on the machine platform for allowing the wire core to pass through and preventing it from bending and sagging, a grinding part rotatably arranged on the retaining component for grinding the outer wall of the wire core, and a driving component for driving the grinding part to rotate.

[0009] Preferably, the grinding part includes a rotating body through which the wire core can pass and which rotates when driven by a driving component, and a grinding piece arranged on the rotating body and approaches the center of the rotating body along the radial direction of the rotating body as the rotating body rotates. At least two groups of grinding pieces are evenly spaced around the axial direction of the rotating body, and an elastic reset piece is arranged at the end of the rotating body to drive the grinding piece away from the wire core when the rotating body stops.

[0010] Preferably, the grinding piece includes a grinding head and a lever fixedly connected to the grinding head at one end. A movable groove is opened on the rotating body along its radial direction and passes through both ends of the rotating body. The middle part of the lever is hinged in the movable groove and both ends of the lever pass through the two ends of the rotating body. A guide groove is opened along the opening direction of the movable groove at the end of the rotating body away from the grinding head. A slider is slidably embedded in the guide groove and moves away from the center of the rotating body driven by centrifugal force as the rotating body rotates. The slider is opened with a through groove for the end of the lever away from the grinding head to pass through.

[0011] By adopting the above scheme, the centrifugal force generated when the rotating body rotates drives the slider away from the center of the rotating body. The slider drives the lever to flip during the process of moving away, and one end of the lever with the grinding head will automatically approach the wire core, and the grinding piece rotates around the wire core while grinding it. The advantage of this method is that the surface of the wire core can be evenly polished, and the wire core after polishing will appear smoother, and the grinding piece can be suitable for wire cores of different diameters. After the diameter of the wire core changes, the grinding piece can still automatically approach and press against the wire core. This scheme sets at least two groups of grinding pieces. If there is only one group of grinding pieces, only one side of the wire core is subjected to force when it is pressed by the grinding piece, and it may deviate from the center of the rotating body. At this time, the wire core is likely to be entangled with the rotating grinding piece, resulting in the inability to polish normally. Therefore, at least two groups of grinding pieces are set to prevent the wire core from deviating and to make the force on the wire core more uniform during polishing.

[0012] Preferably, the retaining component includes a pair of retaining frames arranged at both ends of the rotating body, a rotating drum is rotatably arranged on the retaining frames, and the retaining frames and the rotating drum are rotatably matched through bearings. The rotating body is concentrically arranged in the rotating drum and fixed to the inner wall of the rotating drum.

[0013] By adopting the above scheme, more than one group of rotating bodies can be arranged in the rotating drum, and the grinding heads on each group of rotating bodies can be made of different materials. For example, a coarser grinding head is used to remove the oxide layer first, and then a finer grinding head is used for fine grinding or polishing. In this way, different grinding purposes can be achieved for wire cores of different specifications. All rotating bodies are arranged in the rotating drum, and the driving component can drive all rotating bodies to rotate as long as it drives the rotating drum to rotate.

[0014] Preferably, the elastic reset member is arranged at one end of the slider away from the center of the rotating body, and when the slider is away from the center of the rotating body, the elastic reset member elastically abuts against the inner wall of the drum.

[0015] With the above solution, the function of the spring is to prevent part of the grinding piece from always being in a state close to the center of the rotating body when the rotating body is not rotating.

[0016] Preferably, the driving member comprises a motor fixedly arranged on the machine platform, and the output shaft of the motor is connected to the rotating drum via a transmission mechanism.

[0017] Preferably, a chip discharge port for discharging grinding debris is provided on the outer ring wall of the rotating drum, and a protective cover for preventing grinding debris from splashing and a collection frame for collecting grinding debris are provided on the machine platform.

[0018] Preferably, the cleaning mechanism includes a cleaning box arranged on the machine platform for the wire core to pass through and a water supply component for inputting cleaning liquid into the cleaning box, a drainage component for discharging sewage is arranged below the cleaning box, and a sewage tank is arranged below the drainage component.

[0019] The utility model has significant technical effects due to the adoption of the above technical scheme: in this scheme, when the conveying roller group is conveying the wire core, the grinding mechanism can remove the oxide layer on the surface of the wire core as much as possible by rubbing the surface of the wire core, thereby reducing the influence of the oxide layer on the conductivity of the wire core; the wire core after grinding will be conveyed to the cleaning mechanism to clean up the grinding debris remaining on the wire core; compared with the prior art, the cable cleaning device in this scheme can effectively remove the oxide layer formed on the surface of the waste wire core, so that the wire core can be recycled normally; moreover, the process of removing the oxide layer and the process of cleaning the wire core are seamlessly connected on the same assembly line, eliminating the need for an additional deoxidation treatment step, thereby effectively improving production efficiency.
