[0002] High-voltage cables mainly provide high voltage and strong electricity. Compared with low-voltage cables that do not require shielding protection, due to the high voltage in high-voltage cables, a layer of shielding net is required to form electromagnetic shielding protection. Otherwise, the adjacent electrical devices or equipment will be affected by electromagnetic radiation and then fail. Therefore, it is necessary to avoid the influence of electromagnetic radiation. In high-voltage cables, in addition to the high-voltage cable core that mainly plays a conductive role, the outer surface of the core is also covered with an inner insulation layer, a shielding net and an outer insulation layer in sequence. In order to effectively connect the shielding net with other equipment, the shielding net needs to be connected to the shielding ring, and then connected to other equipment through the shielding ring to ensure that the connection between the shielding net and other equipment meets the relevant electrical requirements.

[0003] For the processing of shielding nets of high-voltage cables, after the shielding nets of the cables are cut off by the cutting assembly, a lot of debris attached to the cut shielding conduit will be generated. If not handled in time, it will cause processing errors in the length of the cut shielding net during the subsequent cable processing, and even affect the one-time cutting of the shielding net, making it difficult to ensure the quality of cable processing and detrimental to the production activities. The prior art uses rigid parts such as copper sheets for cleaning, which will cause wear on the cutting assembly, and the cut shielding conduit needs to be replaced when processing cables of different wire diameters, so the rigid parts need to be replaced accordingly, affecting the processing efficiency of the cable shielding net.

[0026] In some other embodiments, the driving component 120 can also be set at other positions of the workbench 110. Of course, technical personnel in this field can also set the position of the driving component 120 according to actual conditions, as long as it can realize its function of controlling the motion trajectory of the cutting component 150.

[0027] Please combine Figure 1-Figure 2 See also Figure 3-Figure 4 , Figure 3 yes Figure 1 The three-dimensional structural diagram of the working table of the cable shielding net cutting mechanism is shown in FIG. Figure 4 yes Figure 3 The three-dimensional structural schematic diagram of the brush device of the workbench of the cable shielding net cutting mechanism is shown. Optionally, in this embodiment, in order to clean the debris generated in the process step of cutting the shielding net, the workbench 110 is also provided with a brush device 160 for cleaning the cut shielding conduit 151.

[0028] Please continue reading Figure 3 Optionally, in this embodiment, the workbench 110 further includes a second vertical plate 112, a first vertical plate 111, and a third vertical plate 113 sequentially arranged along the length direction of the workbench 110. It can be seen that the brush device 160 is arranged on the first vertical plate 111, the holding assembly is arranged on the left side of the second vertical plate 112, the driving assembly 120 and the cutting assembly 150 are both arranged between the first vertical plate 111 and the third vertical plate 113, the positioning assembly 140 is arranged between the first vertical plate 111 and the second vertical plate 112, and the positioning assembly 140 further includes a guide shaft 141, a first slider 14 2 and the second slider 143, one end of the guide shaft 141 is fixedly connected to the first vertical plate 111, and the other end is fixedly connected to the second vertical plate 112. The number of guide shafts 141 is multiple, the first slider 142 is sleeved on the guide shaft 141 and reciprocates between the first vertical plate 111 and the second vertical plate 112 along the axial direction of the guide shaft 141, and the second slider 143 guides the cable to extend into the positioning assembly 140 through the taper. When the cable shielding net cutting mechanism 100 performs the step of cutting the shielding net, the first slider 142 and the second slider 143 are used together to fix the cable. It should be noted that the terms "first", "second", etc. in the embodiments of the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined by the terms "first", "second", etc. may explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In some other embodiments, the brush device 160 is provided independently of the workbench 110, and can be a device fixed to other positions of the cable shielding net cutting mechanism 100, or a device provided on the cutting assembly 150. Of course, those skilled in the art can also provide the position of the brush device 160 according to actual conditions, as long as the cleaning function can be achieved.

[0030] Please continue reading Figure 4Optionally, in this embodiment, the brush device 160 includes a base 161, bristles 162 and a duct channel 163 running through the base 161, the duct channel 163 is arranged along the length direction of the base 161, the bristles 162 are filled in the duct channel 163, and the duct channel 163 is used for the cut shielding duct 151 to pass through the brush device 160. When the cut shielding duct 151 reciprocates along the length direction of the workbench 110 driven by the cutting component 150, it will repeatedly pass through the duct channel 163 and rub against the bristles 162 in the duct channel 163, so that the debris adhered to the cut shielding duct 151 falls off, so as to achieve the purpose of cleaning the cut shielding duct 151, so as to prevent the adhered debris from causing processing errors in cutting the shielding net during the cable processing process. It should be pointed out that the cross-sectional diameter of the conduit channel 163 is larger than the cross-sectional diameter of the cut shielding conduit 151. When it is necessary to cut shielding nets of different wire diameters, the cut shielding conduit 151 needs to be replaced, but there is no need to replace the brush device 160, which improves the processing efficiency of the cable shielding net.

[0031] Optionally, in this embodiment, the base 161 is cylindrical. Of course, those skilled in the art can also set the shape of the base 161 according to actual conditions, as long as the functions of cleaning and beautiful design can be achieved.

[0032] Please continue reading Figure 2 Optionally, in this embodiment, the positioning assembly 140 also includes a cleaning device 144, which is sleeved on the guide shaft 141. After the process step of cutting the shielding net is completed, the cleaning device 144 is started to jet clean the cable surface, the first slider 142 and the shielding conduit 151. Specifically, the debris splashed onto the cable surface, the first slider 142 and the shielding conduit 151 can be blown away in time, and the debris adhering to the shielding conduit 151 can be processed in advance so that the brush device 160 can clean it smoothly.

[0034] The above is a description of the various structural components, connection relationships and functions of this embodiment. The specific working process of the cable shielding mesh cutting mechanism 100 will be described below in conjunction with this embodiment.

[0035] In the present embodiment, when the cable shielding net cutting mechanism 100 is required to perform the cable shielding net cutting step, first, one end of the cable is fixed by the holding assembly 130, and then the holding assembly 130 starts to slide in the direction of the second vertical plate 112. It can be seen that the other end of the cable is guided by the taper of the second slider 143, passes through the limiting hole and extends into the first slider 142 and is fixed. Then the driving assembly 120 is started to drive the cutting assembly 150 to move, so that the shielding conduit 151 extends into the inner wall of the shielding net. After the shielding net is cut off by high-speed rotation, the cleaning device 144 is started. The cleaning device 144 sprays and cleans the surface of the first slider 142, the shielding conduit 151 and the cable. Finally, driven by the driving assembly 120, the cutting assembly 150 moves away from the cable, and the cable also exits the first slider 142 and the second slider 143 in sequence under the drive of the holding assembly 130, and the step of cutting the shielding net is completed.

[0036] Furthermore, the present invention also provides a wire cutting machine 200, see Figure 5-Figure 6 , Figure 5 This is a three-dimensional structural diagram of an embodiment of the utility model wire cutting machine.

[0037] Specifically, the cable shielding net cutting mechanism 100 is arranged above the electrical control unit 210, and a storage space for placing the electrical control unit 210 is provided above the wire cutting machine 200. The cable shielding net cutting mechanism 100 and the electrical control unit 210 are both covered by the machine cover 220, which can protect the cable shielding net cutting mechanism 100 and the electrical control unit 210 and extend the service life of the wire cutting machine 200.

[0038] Please continue reading Figure 6 Optionally, in this embodiment, the wire cutting machine 200 also includes a collection container 230, which is arranged below the workbench 110 and directly below the positioning assembly 140. The collection container 230 is used to collect shielding net debris, dust and other materials dropped by the cleaning device 144 through jet cleaning, and collect debris and other waste materials brushed off by the brush device 160, to prevent the first slider 142 and the shielding conduit 151 from having shielding net debris, dust and other residues that affect the processing of the cable, while also ensuring the normal operation of the electrical control unit 210.
