DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figure 1-6As shown, the automatic cleaning device of the stranding machine includes a stranding mechanism 1. Above the stranding mechanism 1, a cleaning mechanism 3 is provided. On the outer sides of both the stranding mechanism 1 and the cleaning mechanism 3, a fastening mechanism 2 is provided; further including: The cleaning mechanism 3 includes a translation block 301. In the middle of the translation block 301, an installation groove 302 is opened. At the inner edge of the installation groove 302, a positioning hole 303 is opened. On both sides inside the installation groove 302, mounting plates 304 are snap-connected. At the edge of one side of the mounting plate 304, a positioning shaft is fixedly connected. The mounting plate 304 is inserted into the inner wall of the positioning shaft and the inner side of the positioning hole 303; Among them, on the surface of each mounting plate 304, a wire management groove 305 is opened, and a cleaning brush 306 is fixedly connected to the inner side wall of the wire management groove 305; Among them, a sliding frame 307 is slidably connected to the inner wall of the translation block 301 and below the installation groove 302. The bottom surface of the sliding frame 307 is hollowed out, and a dust-proof net 308 is fixedly installed on the inner side of the bottom surface of the sliding frame 307, as Figure 4 , Figure 5 shown, the positioning shaft at the side edge of the mounting plate 304 can fit with the positioning hole 303;

[0030] On the inner wall of the translation block 301 and below the dust-proof net 308, a blower 309 is fixedly installed. The negative pressure end of the blower 309 is arranged upward. On the inner wall of the translation block 301 and below the blower 309, an air outlet 310 is opened. One end of the air outlet 310 extends to the surface of the translation block 301, as Figure 5-Figure 6 shown, the blower 309 exhausts air through the air outlet 310;

[0031] The stranding mechanism 1 includes a base 101. On one side of the top of the base 101, an electric cylinder 102 is fixedly installed. The extending end of the electric cylinder 102 is fixedly connected with a slider 103. On the top of the slider 103, a guide rod 104 is fixedly connected. The length direction of the guide rod 104 is the same as the length direction of the slider 103. A spring 105 is sleeved on the outer side wall of the guide rod 104. One side of the spring 105 is fixedly connected with the top of the slider 103, as Figure 1 shown, since the cable gradually shortens during the stranding process, the elongation rate of the electric cylinder 102 may not match the shortening rate of the cable. Therefore, the spring 105 serves as a buffer during the stranding of the cable to prevent the cable from being pulled apart;

[0032] On the top surface of the base 101, a movable vertical plate 106 is slidably connected. The middle of the bottom of the movable vertical plate 106 is slidably connected along the slider 103. The movable vertical plate 106 abuts against the side of the spring 105. On the top surface of the base 101 and on the side away from the electric cylinder 102, a fixed vertical plate 107 is fixedly installed. On one side of the top surface of the fixed vertical plate 107, a motor 108 is fixedly installed. On the top surface of the base 101 and between the fixed vertical plate 107 and the movable vertical plate 106, it is slidably connected with the translation block 301, as Figure 1 shown, the translation block 301 can move along the length direction of the cable above the base 101;

[0033] The fastening mechanism 2 includes a connecting plate 201. Clamping grooves 202 are symmetrically formed on both sides of the surface of the connecting plate 201. The inner diameter of the clamping grooves 202 gradually increases towards the edge of the connecting plate 201. A limiting rail 203 is formed at the upper end of the surface of the connecting plate 201. The length direction of the limiting rail 203 is the same as the length direction of the connecting plate 201. A lead screw 204 is rotatably connected to the top of the connecting plate 201. One end of the lead screw 204 passes through the connecting plate 201 and is fixedly connected to a knob 205. The threads on both sides of the surface of the lead screw 204 are in opposite directions, and extrusion blocks 206 are threadedly sleeved on both sides of the surface of the lead screw 204. The lower end of the extrusion block 206 extends below the clamping groove 202, and the surface of the extrusion block 206 is slidably connected along the limiting rail 203. As Figure 2 shown, when the lead screw 204 rotates, it pushes the two extrusion blocks 206 to move in opposite directions through the threads with opposite directions on both sides;

[0034] One side of the top surface of the movable vertical plate 106 is fixedly installed with the connecting plate 201. One side of the top surface of the fixed vertical plate 107 is rotatably connected to another connecting plate 201. The output shaft of the motor 108 passes through the fixed vertical plate 107, and the output shaft of the motor 108 is fixedly connected to the middle of the connecting plate 201. As Figure 1 shown, the motor 108 drives the fastening mechanism 2 on one side, so that the cable is gradually stranded.

[0035] The working principle of the present utility model:

[0036] When the device is in use, both ends of the cable to be stranded are respectively placed inside the clamping grooves 202 of the fastening mechanisms 2 on both sides. At the same time, the middle of the cable needs to pass through the installation groove 302. When fixing, rotate the knob 205 to drive the lead screw 204 to rotate, so that the lead screw 204 pushes the two extrusion blocks 206 to close inwards along the limiting rail 203, and then the extrusion blocks 206 press the cable in the clamping groove 202;

[0037] When cleaning the surface of the cable, place the mounting plates 304 on both sides inside the installation groove 302. After the positioning shafts are inserted into the positioning holes 303 and fixed, then start the blower 309 and push the translation block 301 to slide along the base 101, so that the cleaning brushes 306 inside the cable groove 305 scrape along the surface of the cable and remove impurities. The blower 309 drives the impurities to fall into the sliding frame 307 through the air flow, and the dust-proof net 309 intercepts the impurities;

[0038] When stranding, remove the mounting plates 304 again, start the motor 108 to drive the connecting plate 201 on one side to rotate, and start the electric cylinder 102 to gradually extend its extension end, then the cable is gradually stranded.

[0039] The above has described in detail an embodiment of the present utility model, but the above content is only a preferred embodiment of the present utility model and cannot be considered as defining the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
