DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-6 A cable cutting device for cable production includes a base 1, which is installed on a wrapping machine. The center of the base 1 is hollow, and a cable 2 is slidably connected to the hollow part. A limiting mechanism 3 is installed on the base 1, and a cutting mechanism 4 is transmission-connected to the limiting mechanism 3. The limiting mechanism 3 includes a protective shell 301 installed on the base 1, a connecting plate 302 is installed on the protective shell 301, a first gear 303 is rotatably installed between the connecting plate 302 and the base 1, a second gear 304 is meshed on the first gear 303, the second gear 304 is rotatably installed on the base 1 and a servo motor 305 is connected at its axis, a plurality of moving rods 306 are slidably connected to the base 1, a side of the moving rod 306 away from the base 1 is slidably connected to the first gear 303, and the ends of the plurality of moving rods 306 close to each other are elastically connected to limiting plates 307, and the plurality of limiting plates 307 are located on the periphery of the cable 2.

[0027] Before cutting the cable 2, it is necessary to limit its position through the limiting mechanism 3. When the limiting mechanism 3 is running, the servo motor 305 is first turned on. The servo motor 305 drives the second gear 304 to rotate, thereby pushing the first gear 303 to rotate, so that several moving rods 306 slidingly connected to the first gear 303 move toward the center of the device. When the moving rod 306 moves, it drives the limiting plate 307 elastically connected to it to move synchronously until it contacts the cable 2, thereby achieving the purpose of limiting the cable 2 at the center of the device, avoiding shaking and uneven cut surface when the cable 2 is subsequently cut.

[0028] Reference Figure 2 , Figure 4 In this embodiment, a plurality of connecting grooves 309 are provided on the first gear 303, and a connecting shaft 310 is installed on the side of a plurality of moving rods 306 close to the first gear 303. The plurality of connecting shafts 310 are slidably fitted in the corresponding connecting grooves 309, so that the moving rods 306 can be slidably connected to the first gear 303 through the adaptability of the connecting shafts 310 and the connecting grooves 309, so that when the first gear 303 rotates, it can drive the plurality of moving rods 306 to move synchronously, so that the plurality of moving rods 306 can approach or move away from each other.

[0029] Reference Figure 4 In this embodiment, a plurality of slide grooves 308 are provided on one side of the base 1 close to the moving rod 306, and the moving rod 306 is slidably fitted in the slide groove 308, so that when the first gear 303 drives the moving rod 306 to move, the slide groove 308 restricts the moving rod 306, so that the moving rod 306 can only move along the direction of the slide groove 308, so that the limiting piece 307 installed on the moving rod 306 can contact the cable 2 at the center of the positioning device, thereby achieving the purpose of limiting the cable 2.

[0030] Reference Figure 4 In this embodiment, a spring 311 is installed inside each of the moving rods 306. The end of the spring 311 away from the moving rod 306 is connected to the corresponding limiting plate 307, so that when the moving rod 306 moves, it can drive the limiting plate 307 to move synchronously. When the limiting plate 307 has contacted the cable 2 and the first gear 303 is still in a rotating state, the spring 311 can play a buffering role to prevent the cable 2 from being squeezed by the limiting plate 307 and causing damage to the cable 2.

[0031] Reference Figure 5In this embodiment, the cutting mechanism 4 includes two third gears 401 rotatably connected to the connecting plate 302, the two third gears 401 are meshed with an arc-shaped rack 402, the ends of the two third gears 401 away from the arc-shaped rack 402 are meshed with a movable plate 403, the movable plate 403 and the arc-shaped rack 402 are both slidably connected to the connecting plate 302, and the first blade 404 and the second blade 411 are rotatably installed on the two movable plates 403 respectively, the first blade 404 and the second blade 411 are connected to a power supply and driven by the power supply, and two first transmission shafts 405 are installed on the first gear 303, and the ends of the two first transmission shafts 405 close to the first blade 404 and the second blade 411 pass through the connecting plate 302.

[0032] When the first gear 303 rotates until the first transmission shaft 405 installed thereon contacts the arc-shaped rack 402, the cutting mechanism 4 operates. At this time, the first transmission shaft 405 contacts the arc-shaped rack 402 and pushes the two arc-shaped racks 402 to move on the connecting plate 302, so that the third gear 401 meshing with the arc-shaped rack 402 rotates, thereby driving the two moving plates 403 to approach each other, so that the first blade 404 and the second blade 411 installed on the moving plate 403 move synchronously toward the cable 2. The first blade 404 and the second blade 411 are driven to rotate by the power supply when contacting the cable 2, thereby achieving the purpose of the moving plate 403 moving to drive the blade 404 to cut the cable 2.

[0033] Reference Figure 6-7 In this embodiment, a notch is provided at the edge of the first blade 404, and the edge of the second blade 411 is pointed, so that the first blade 404 and the second blade 411 can smoothly transition when they intersect without colliding and causing damage to the first blade 404 and the second blade 411.

[0034] Reference Figure 5 In this embodiment, two transmission grooves 406 are provided on the connecting plate 302. The two transmission grooves 406 are circumferentially distributed on the connecting plate 302 and are adapted to the first transmission shaft 405, so that the two first transmission shafts 405 can contact the arc-shaped rack 402 through the transmission grooves 406, so that when the first gear 303 rotates, the arc-shaped rack 402 is pushed to move through the transmission shaft 405, thereby realizing the power transmission of the cutting mechanism 4.

[0035] Reference Figure 5In this embodiment, two second transmission shafts 407 are installed on the first gear 303, and the two second transmission shafts 407 are slidably adapted in the corresponding transmission grooves 406, so that after the first blade 404 and the second blade 411 complete cutting of the cable 2, the servo motor 305 rotates in the opposite direction, which can drive the two second transmission shafts 407 to move synchronously, thereby pushing the arc-shaped rack 402 to move in the opposite direction, thereby driving the first blade 404 and the second blade 411 to move away from each other and reset to the starting position, so as to facilitate the next cable 2 cutting work.

[0036] Reference Figure 5 In this embodiment, connecting blocks 408 are installed at both ends of the two arc-shaped racks 402, so that the first transmission shaft 405 and the second transmission shaft 407 can contact the connecting blocks 408 when moving, thereby pushing the corresponding arc-shaped racks 402 to move through the connecting blocks 408.

[0037] Reference Figure 5 In this embodiment, limiting grooves 409 are provided on the two movable plates 403, and two limiting shafts 410 are installed on the connecting plate 302. The two limiting shafts 410 are slidably adapted in the corresponding limiting grooves 409, so that the movable plate 403 is slidably connected to the connecting plate 302 through the adaptability of the limiting grooves 409 and the limiting shafts 410. When the third gear 401 drives the movable plate 403 to move, the movable plate 403 is restricted by the limiting grooves 409 to move only in the horizontal direction, thereby providing guidance for the moving direction of the first blade 404 and the second blade 411, so that the first blade 404 and the second blade 411 can move toward the position where the cable 2 is located, thereby achieving the purpose of cutting the cable 2.
