Description

Technical Field

[0001] This utility model relates to the field of cable recycling technology, and in particular to an automatic wire cutting and stripping machine. Background Technology

[0002] Electric wires are the basic material for power transmission and signal transmission, and are widely used in homes, industry, communications, transportation and other fields. Their structure usually consists of core parts such as conductors, insulation layers, shielding layers, and sheathing layers. The core conductive parts usually contain copper, aluminum, metal alloys, etc.

[0003] Because electrical wires contain metal, failure to recycle them after disposal leads to resource waste. The recycling process typically involves using a wire stripper to cut open the outer insulation layer and extract the internal electrical core. However, when processing wires of different diameters, it's necessary to frequently change cutting blades of different sizes to achieve the desired cutting depth, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic wire cutting and stripping machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: It includes a platform, characterized in that: a conveying assembly is provided on the top of the platform; a first support is fixedly connected to the top of the platform; multiple connecting rods are fixedly connected to the side wall of the first support; a connecting plate is fixedly connected to the end of each connecting rod; a first threaded hole is opened in the middle of the connecting plate; a first screw is threadedly connected to the middle of the first threaded hole; multiple first through holes are opened in the middle of the connecting plate; a first limiting rod is slidably connected within each first through hole; a first cutting blade is rotatably installed at the end of the first screw; and the end of the first limiting rod is fixedly connected to the top of the first cutting blade. By providing the first screw, turning the first screw causes the first cutting blade to move downwards. When the first cutting blade moves downwards, it cuts into the cable protection layer. The required cutting depth can be achieved by turning the first screw, thus realizing the control of the cutting depth.

[0006] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves: by setting a first screw, turning the first screw causes the first cutting blade to move downward, and the first cutting blade cuts into the cable protection layer when it moves downward. The first cutting blade can achieve the required cutting depth by turning the first screw, thus realizing the control of the cutting depth.

[0007] This device is equipped with a conveying assembly. When the first motor and the second motor are started, the first motor rotates clockwise and the second motor rotates counterclockwise. The first motor drives the upper pressure roller to rotate clockwise, and the second motor drives the lower pressure roller to rotate counterclockwise. When one pressure roller is moving, it drives the other pressure rollers in the same group to rotate synchronously through gears and chains. When the two groups of pressure rollers are moving, they squeeze and convey the cable forward, realizing the squeezing and conveying of the cable.

[0008] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0018] Please see Figure 1 , Figure 4 , Figure 5 This utility model provides an automatic wire cutting and stripping machine, including a platform 11. The platform 11 has a conveying assembly 2 at its top, a first bracket 12 fixedly connected to the top of the platform 11, multiple connecting rods 13 fixedly connected to the side wall of the first bracket 12, a connecting plate 14 fixedly connected to the end of each connecting rod 13, a first threaded hole 15 in the middle of the connecting plate 14, a first screw 1 threadedly connected to the middle of the first threaded hole 15, multiple first through holes 16 in the middle of the connecting plate 14, a first limiting rod 17 slidably connected within each of the first through holes 16, a first cutting blade 18 rotatably mounted at the end of each of the first screws 1, and the end of the first limiting rod 17 fixedly connected to the top of the first cutting blade 18. In use, the cable is installed onto the conveying assembly 2, then one end of the cable is threaded into the first bracket 12, and the first screw 1 is turned... A screw 1 drives the first cutting blade 18 to move downwards, and the first limiting rod 17 moves downwards synchronously within the first through hole 16. The first limiting rod 17 can limit the first cutting blade 18, keeping it moving vertically. When the first cutting blade 18 moves downwards, it cuts into the cable protective layer, activating the conveying component 2. The conveying component 2 conveys the cable forward. When the cable moves forward, it is squeezed and collided with the first cutting blade 18, thus stripping the cable. The first cutting blade 18 can be adjusted to the required cutting depth by turning the first screw 1, thus achieving control over the cutting depth. By setting the first screw 1, turning the first screw 1 drives the first cutting blade 18 to move downwards, and the first cutting blade 18 cuts into the cable protective layer when it moves downwards. The first cutting blade 18 can be adjusted to the required cutting depth by turning the first screw 1, thus achieving control over the cutting depth.

[0019] Please see Figures 1 to 3The conveying assembly 2 includes a second bracket 21, which is fixed to the top of the platform 11. A first motor 22 and a second motor 23 are fixed to the side wall of the second bracket 21. Multiple rotating shafts 24 are rotatably mounted on the side wall of the second bracket 21. The output ends of the first motor 22 and the second motor 23 respectively pass through the second bracket 21 and are fixed to the end of one of the rotating shafts 24. A pressure roller 25 is fixed to the end of the rotating shaft 24, and a gear 26 is fixed to the middle of the rotating shaft 24. A chain 27 meshes with the gear 26. In use, one end of the cable is inserted between two pressure rollers 25, and the first motor 22 and the second motor 23 are started, causing the first motor 22 to rotate clockwise and the second motor 23 to rotate counterclockwise. The first motor 22 drives the pressure roller 25 located above. The first motor 22 rotates clockwise, while the second motor 23 drives the lower pressure roller 25 to rotate counterclockwise. When one pressure roller 25 moves, it drives the other pressure rollers 25 in the same group to rotate synchronously through the gear 26 and chain 27. When the two sets of pressure rollers 25 move, they squeeze and convey the cable forward, realizing the compression and conveying of the cable. With the conveying component 2, the first motor 22 and the second motor 23 are started, so that the first motor 22 rotates clockwise and the second motor 23 rotates counterclockwise. The first motor 22 drives the upper pressure roller 25 to rotate clockwise, and the second motor 23 drives the lower pressure roller 25 to rotate counterclockwise. When one pressure roller 25 moves, it drives the other pressure rollers 25 in the same group to rotate synchronously through the gear 26 and chain 27. When the two sets of pressure rollers 25 move, they squeeze and convey the cable forward, realizing the compression and conveying of the cable.

[0020] Please see Figure 1 , Figure 6 A cylinder 31 is fixedly connected to the bottom of the platform 11, and a third support 32 is fixedly connected to the top of the platform 11. A push rod 33 is fixedly connected to the output end of the cylinder 31 through the platform 11, and a second cutting blade 3 is fixedly connected to the end of the push rod 33. In use, the cylinder 31 is activated, which drives the push rod 33 to rise. The second cutting blade 3 moves synchronously. When the second cutting blade 3 moves upward, it presses against the side wall of the third support 32, which can cut the cable located between the second cutting blade 3 and the third support 32, thus achieving cable cutting.

[0021] Please see Figures 4 to 5The first bracket 12 has multiple second threaded holes 41 in the middle, and a second screw 42 is internally threaded into each second threaded hole 41. A clamping piece 4 is rotatably installed at the end of the second screw 42. In use, when the second screw 42 is turned, the second screw 42 drives the clamping piece 4 to move. The multiple clamping pieces 4 can limit the cable being transmitted forward by the conveying component 2, making it easier for the first cutting blade 18 to cut. The distance between the multiple clamping pieces 4 can also be adjusted according to the size of different cables, thus achieving the limitation of cables of different sizes. By setting the clamping pieces 4, turning the second screw 42 drives the clamping pieces 4 to move. The multiple clamping pieces 4 can limit the cable being transmitted forward by the conveying component 2, making it easier for the first cutting blade 18 to cut. The distance between the multiple clamping pieces 4 can also be adjusted according to the size of different cables, thus achieving the limitation of cables of different sizes.

[0022] Please see Figures 4 to 5 The first bracket 12 has a plurality of second through holes 51 in the middle. A second limiting rod 5 is slidably connected in the second through hole 51. The end of the second limiting rod 5 is fixed to the side wall of the clamping piece 4. By providing the second limiting rod 5, when the clamping piece 4 moves, the second limiting rod 5 slides in the second through hole 51. The second limiting rod 5 can limit the clamping piece 4 and prevent the clamping piece 4 from deflecting during movement.

[0023] Please see Figure 1 A control box 6 is fixedly connected to the top of the platform 11. The control box 6 is used to control the start and stop of the first motor 22, the second motor 23, and the cylinder 31. By setting the control box 6, the start and stop of the first motor 22, the second motor 23, and the cylinder 31 can be controlled.

[0024] Please see Figures 1 to 3 A rubber pad 7 is fixedly attached to the surface of the pressure roller 25, and the rubber pad 7 is located at the center of the pressure roller 25. By providing the rubber pad 7, the friction between the pressure roller 25 and the cable is increased, making it easier to transmit the cable.
