[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.

Optionally, in this embodiment, the positioning component 140 includes a guide shaft 141, a wire release slider 142, a wire slider 143 and a positioning detection device 144. 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, and the wire slider 143 is sleeved on the guide shaft 141 and can be axially moved between the first vertical plate 111 and the second vertical plate 112 along the guide shaft 141.

It can be seen that one end of the fixing block 1443 is provided with The space adapted to the sensor 1444 and the sensor 1444 is fixed. The column 1442 can be fixed to the support seat 1441 at different positions in its axial direction to achieve the purpose of adjusting the height difference between the sensor 1444 and the support seat 1441 and the angle between the sensor 1444 and the cable, so that the sensor 1444 can be more accurately aligned with the wire slider 143.

[0034] In some other embodiments, the upright post 1442 is slidably connected to the support base 1441, so that the height difference between the sensor and the support base 1441 and the angle between the sensor 1444 and the cable can be adjusted more quickly.

Of course, those skilled in the art can also select the type of sensor 1444 according to actual conditions, as long as the function of controlling the length of the cable extending into the positioning assembly 140 can be achieved.

[0036] Please combine Figure 5 See also Figure 6 , Figure 6 yes Figure 5 The three-dimensional structural schematic diagram of the support base of the positioning detection device of the positioning component of the cable shielding net cutting and flipping mechanism is shown. Optionally, in this embodiment, the cross-section of the support base 1441 is L-shaped.

[0037] In some other embodiments, the support base 1441 is fixed to the workbench 110. Of course, those skilled in the art can also set the position of the support base 1441 according to actual conditions, as long as the sensor 1444 can be fixed.

[0038] As for other structural features of the driving assembly 120 , the holding assembly 130 , the cutting assembly 150 and the flipping assembly 160 , they are within the scope of understanding of those skilled in the art and will not be elaborated here.

[0039] 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 net cutting and flipping mechanism 100 will be described below in conjunction with this embodiment.

[0040] In this embodiment, when the cable shielding net cutting and flipping mechanism 100 is required to perform the cable shielding net cutting and flipping steps, first fix one end of the cable through the holding assembly 130, then start the holding assembly 130 to slide in the direction of the first vertical plate 111, and the other end of the cable passes through the wire release slider 142 and the wire slider 143 in turn, and extends into the positioning assembly 140. When the other end of the cable extends into the wire slider 143, it will be detected by the sensor 1444 of the positioning detection device 144, and then the length of the cable extending into the wire slider 143 is fixed according to the preset value in conjunction with the holding assembly 130 and the wire slider 143, so that the subsequent process steps of cutting the shielding net can be carried out. After the fixing is completed, the wire slider 143 repeatedly squeezes and rolls the shielding net, so that the shielding net of the cable is slightly unfolded, and then the driving assembly 120 drives the cutting assembly 150 to extend into the positioning assembly 140 and rotate to cut the shielding net of the cable, and the step of cutting the shielding net is completed. Under the action of the driving assembly 120, the cutting assembly 150 is away from the positioning assembly 140. Next, the step of flipping the shielding net is performed. Since the pay-off slider 142 will affect the flipping of the cable shielding net, it is necessary to first use the holding component 130 to make the cable exit the pay-off slider 142, and then the pay-off slider 142 slides along the side of the first vertical plate 111 in the width direction of the workbench 110, and the cable enters the wire slider 143 through the holding component 130. When the cable passes through the wire slider 143, it will be detected by the sensor 1444 and the length of the cable extending into the wire slider 143 is controlled according to the preset value. The driving component 120 drives the cutting component 150 to fix the other end of the cable, and then the shielding net is fully opened through the wire slider 143. The flipping component 160 is started to turn the already opened shielding net outward, and the step of flipping the shielding net is completed. The driving component 120 moves away from the positioning component 140, and the flipping component 160 exits the positioning component 140 driven by the driving component 120, waiting for the next shielding net cutting and flipping steps to be executed. The positioning detection device 144 makes the connection between the cutting and flipping steps of the shielding net more compact, and also makes the interval between processing each cable shorter, thereby improving the production and processing efficiency of the cable, while reducing errors and reducing the processing difficulty for operators.

[0041] Furthermore, the present invention also provides a wire cutting machine 200, see Figure 7-Figure 8 , Figure 7 This is a three-dimensional structural diagram of an embodiment of the utility model wire cutting machine.

The cable shielding net cutting and flipping mechanism 100 and the electrical control unit 210 are both covered by a machine cover 220, which can protect the cable shielding net cutting and flipping mechanism 100 and the electrical control unit 210 and extend the service life of the wire cutting machine 200.
