Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A wire cutting device, such as Figures 1-4 As shown, the device includes a base plate 1 and a placement plate 2 fixedly connected to the base plate 1. Two positioning frames 3 are slidably connected to the placement plate 2. A conveying roller 4 is rotatably connected to the bottom side of the positioning frame 3. A spring telescopic rod 5 is fixedly connected to the top side of the positioning frame 3. A conveying roller 6 is rotatably connected to the telescopic end of the spring telescopic rod 5. A cutting assembly for cutting cables is provided on the positioning frame 3. The cutting assembly includes a cutter 7 fixedly connected to the bottom side of the positioning frame 3, several electric push rods 8 fixedly connected to the top side of the positioning frame 3, a connecting plate 9 fixedly connected between the several electric push rods 8, and a cutter 10 fixedly connected to the connecting plate 9. A tensioning component for tightening cables is provided on the connecting plate 9 and the conveying roller 4. The tensioning component includes two racks 11 fixedly connected to the connecting plate 9 and gears 12 fixedly connected to both ends of the conveying roller 4. The two racks 11 mesh with the two gears 12 respectively.

[0021] like Figures 1-4 As shown, during cable cutting, one side of the conveyor roller 26 can be raised first, and the cable can be passed between the conveyor roller 14 and the conveyor roller 26 on this side. Then, this side of the conveyor roller 26 can be lowered. Next, the other side of the conveyor roller 26 can be raised, and the cable can be passed between the other side of the conveyor roller 14 and the conveyor roller 26. Then, the electric push rods 8 fixedly connected to the two positioning frames 3 can be activated to extend. Subsequently, the electric push rods 8 will drive the two cutters 210 to move closer to the adjacent cutter 17. When the electric push rods 8 drive the cutter 210 to move downward through the connecting plate 9, the connecting plate 9 will also drive the rack 11 to move downward. At this time, the rack 11 will drive the gear 12 that meshes with it to rotate. When the gear 12 rotates, it will drive the conveyor roller 4 to rotate. At this time, the conveyor roller 4 will rotate to the side of the adjacent rack 11. When the two conveyor rollers 4 rotate, the cable can be tightened and kept in a taut state. At the same time, the cutter 2 10 will also contact the upper side of the cable to restrict the cable. Then, the electric push rod 8 continues to extend the cutter 2 10, which can cooperate with the cutter 1 7 to cut the cable. This method can avoid the cable from becoming loose due to its own weight, greatly improve the cutting accuracy, and eliminate the need for manual adjustment of the clamping device, making it more convenient.

[0022] like Figures 1-2 As shown, a positioning frame 13 is fixedly connected to the positioning frame 3, and two spring telescopic rods 14 are fixedly connected to the positioning frame 13. A pushing rod 15 is fixedly connected to the spring telescopic rods 14. When the two adjacent spring telescopic rods 14 are in their natural state, the two pushing rods 15 are in contact with each other. When the cable is placed between the first conveyor roller 4 and the second conveyor roller 6, the two pushing rods 15 are first manually separated. At this time, the spring telescopic rods 14 will be in a retracted state. Then, the cable is placed between the two pushing rods 15. Next, the raised second conveyor roller 6 is released so that the second conveyor roller 6 contacts the cable. Then, the two pushing rods 15 are released again, and the two spring telescopic rods 14 will push the cable so that the cable is in the center position between the first conveyor roller 4 and the second conveyor roller 6. This can prevent the cable from being misaligned when the cable is tightened, which would lead to a decrease in cutting accuracy.

[0023] like Figures 1-4 As shown, positioning blocks 16 are fixedly connected to the bottom sides of both positioning frames 3. The positioning blocks 16 are slidably connected to the placement plate 2. A bidirectional threaded rod 17 is rotatably connected to the bottom side of the placement plate 2. The two positioning blocks 16 are respectively threaded to the two threads on the bidirectional threaded rod 17. A rotating handle 18 is fixedly connected to one end of the bidirectional threaded rod 17. When the cutting distance needs to be adjusted, the rotating handle 18 can be manually rotated to make the bidirectional threaded rod 17 rotate. When the bidirectional threaded rod 17 rotates, it can drive the two positioning blocks 16 to move away from each other or move closer to each other. When the two positioning blocks 16 move away from each other or move closer to each other, the two positioning frames 3 will also move away from each other or move closer to each other. In this way, the cutting distance can be adjusted, thereby increasing the practicality of the cutting device.

[0024] Working principle: When cutting cables, first lift one side of the conveyor roller 26, then manually separate the two push rods 15. At this time, the spring telescopic rod 24 will be in a retracted state. Then place the cable between the two push rods 15, and then release the lifted conveyor roller 26 to make it contact the cable. Then release the two push rods 15 again, and the two spring telescopic rods 24 will push the cable, so that the cable is in the center position between the conveyor roller 14 and the conveyor roller 26. Then lift the other side of the conveyor roller 26, and similarly pass the cable through the other side of the conveyor roller 14 and the conveyor roller 26. Then, the electric push rods 8 fixedly connected to the two positioning frames 3 can be activated to extend. Then, the electric push rods 8 will drive the two cutters 210 to move towards the adjacent cutter 17. As the electric push rod 8 moves downwards via the connecting plate 9, the second cutter 10 also moves downwards, causing the rack 11 to move downwards. The rack 11 then drives the gear 12, which meshes with it, to rotate. As the gear 12 rotates, it drives the first conveyor roller 4 to rotate. The first conveyor roller 4 then rotates to the side of the adjacent rack 11. The rotation of the two conveyor rollers 4 tightens the cable, keeping it taut. At the same time, the second cutter 10 contacts the upper side of the cable to restrict its movement. Then, the electric push rod 8 continues to extend the second cutter 10, which works with the first cutter 7 to cut the cable. This method avoids the cable from becoming loose due to its own weight, greatly improves the cutting accuracy, and eliminates the need for manual adjustment of the clamping device, making it more convenient.
