Description

Technical Field

[0001] The utility model belongs to the technical field of cable processing devices, and in particular relates to a power cable stripping device. Background Art

[0002] The composition of the cable mainly includes one or more mutually insulated conductors and an outer insulating protective layer for wrapping the conductors. The main function of the cable is to transmit electricity or information from one place to another. The use of cables is very popular and can be seen everywhere in life. The cables can be recycled after use. When recycling, the outer insulating protective layer needs to be peeled off from the metal conductor to achieve classified recycling of the plastic protective layer and the metal conductor. Therefore, a power cable stripping device is needed. In the prior art, there is a wire stripping device with a patent application number of "CN202321362093.3".

Detailed implementation manners

[0031] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] As Figures 1-5 shown, a power cable stripping device of the present utility model includes a base 1. A first installation groove 11 is formed in the center of the interior of the base 1. Two openings 12 communicating with the first installation groove 11 are vertically formed in the top of the base 1. A second installation groove 13 is formed in the right side of the top of the base 1;

[0033] Assembly boxes 2, two of them are symmetrically arranged front and back and slidably assembled inside the first installation groove 11;

[0034] Conveying assemblies 3, four of them are provided. The four conveying assemblies 3 are divided into two groups in pairs and are respectively rotatably assembled on the tops of the two assembly boxes 2 through connecting rods 31. The two connecting rods 31 on the left and right sides are respectively located inside the two openings 12. Specifically, the conveying assembly 3 includes a circular block 32. The circular block 32 is fixedly installed on the top of the connecting rod 31. An arc-shaped groove is formed around the circumference of the circular block 32. A number of arc-shaped engaging teeth 33 are assembled around the inner wall of the arc-shaped groove. In the initial state, the four conveying assemblies are distributed in a rectangle. When the cable needs to be stripped, one end of the cable is placed on the side where the two circular blocks 32 of the front and back groups are close to each other. When the transmission assembly is started, the two circular blocks 32 at the rear rotate in the same direction, the two circular blocks 32 at the front rotate in the same direction, and the two circular blocks 32 at the rear rotate in the opposite direction to the two circular blocks 32 at the front. After one end of the cable is placed, the four circular blocks 32 jointly generate a driving force to push the cable towards the cutting piece 8, and it can ensure that the cable is in a vertical state during cutting. The provided arc-shaped engaging teeth 33 can directly engage with the plastic wrapping layer of the cable. When the plastic wrapping layer engages with the arc-shaped engaging teeth 33, deformation will occur, generating a stable driving force, and the arc-shaped structure can be applicable to cables of different thicknesses and sizes, with strong applicability.

[0035] There are four transmission components 4, which are arranged in pairs, and the four transmission components 4 are respectively and fixedly installed inside two assembly boxes 2. The four transmission components 4 are used to drive the four transmission components 3 to rotate. Specifically, the transmission component 4 includes a gear 41. The lower end of the connecting rod 31 extends into the assembly box 2 and is fixedly installed with a crown gear 42. The gear 41 is rotatably assembled on the inner wall of the assembly box 2 on the side away from the center of the base 1. The gear 41 meshes with the crown gear 42.

[0036] Two tooth columns 43 are rotatably assembled on the inner walls of the front and rear sides of the first installation groove 11. Two through holes 44 are opened on the side of the two assembly boxes 2 close to each other. The two tooth columns 43 are respectively located inside the two through holes 44. The two gears 41 on the left and right sides respectively mesh with the two tooth columns 43.

[0037] Assembly rods are fixedly installed on the front sides of the two tooth columns 43. The front ends of the two assembly rods both extend out of the base 1 and are fixedly installed with transmission wheels 45. A transmission belt 46 is commonly assembled between the two transmission wheels 45. A protection box 47 is fixedly installed on the front side of the base 1. A motor 48 is fixedly installed on the front side of the protection box 47. The output shaft of the motor 48 is in transmission connection with one of the transmission wheels 45.

[0038] When it is necessary to use the transmission component 4 to drive the circular block 32 to rotate, such as Figure 4 and Figure 5 As shown, the two gears 41 at the rear side and the two gears at the front side are mirror - set with the center point at the center of the first installation groove 11 opened on the base 1. When in use, start the motor 48. The motor 48 drives one transmission wheel 45 to rotate, and then drives the two transmission wheels 45 to rotate synchronously through the transmission belt 46. Then the two tooth columns 43 will rotate synchronously. Since the two gears 41 on the left and right sides respectively mesh with the two tooth columns 43, all four gears 41 will rotate. When the four gears 41 rotate, they will drive the four crown gears 42 to rotate synchronously through meshing with the four crown gears 42, and the rotation directions of the two crown gears 42 at the rear side and the two crown gears 42 at the front side are opposite, thereby realizing the synchronous rotation of the four circular blocks 32.

[0039] There are two first moving blocks 5, and the two first moving blocks 5 are symmetrically slidably assembled in the second installation groove 13 in the front - rear direction.

[0040] Adjusting assembly 6, the adjusting assembly 6 is installed inside the second installation groove 13, and the adjusting assembly 6 is used to drive the two first moving blocks 5 to approach or move away from each other; specifically, the adjusting assembly 6 includes a second bidirectional threaded rod 61, one end of the second bidirectional threaded rod 61 is rotatably connected to the inner wall of the rear side of the second installation groove 13, the front end of the second bidirectional threaded rod 61 sequentially passes through the two first moving blocks 5 and extends out of the base 1, a second wrench 62 is fixedly installed at the front end of the second bidirectional threaded rod 61, the front first moving block 5 is threadedly connected to the positive threaded section of the second bidirectional threaded rod 61, and the rear first moving block 5 is threadedly connected to the reverse threaded section of the second bidirectional threaded rod 61; during use, only by rotating the second wrench 62, the second bidirectional threaded rod 61 can be driven to rotate, and then when the second bidirectional threaded rod 61 rotates, the two first moving blocks 5 can be driven to approach or move away from each other, and the operation is simple and convenient.

[0041] Mounting assemblies 7, there are two of them, and the two mounting assemblies 7 are respectively installed on the tops of the two first moving blocks 5; specifically, the mounting assembly 7 includes a threaded rod 71, a slide rod 72 and an assembly block 73, the threaded rod 71 is rotatably assembled on the top of the first moving block 5, the slide rod 72 is fixedly installed on the top of the first moving block 5, the assembly block 73 is slidably assembled on the periphery of the slide rod 72, and the assembly block 73 is threadedly connected to the threaded rod 71;

[0042] Two cutting members 8 are respectively fixedly installed on one side of the two assembly blocks 73 close to each other, and third wrenches 74 are fixedly installed at the upper ends of the two threaded rods 71.

[0043] During use, the two cutting members 8 are aligned. According to the diameter of the cable, the two first moving blocks 5 can be adjusted to approach or move away from each other, and then the distance between the two cutting members 8 can be adjusted. And the two cutting members 4 need to be aligned with the center point of the cable. Therefore, according to the thickness of different cables, the two third wrenches 74 can be rotated in sequence. The two third wrenches 74 will drive the assembly block 73 to move up and down through the threaded connection between the assembly block 73 and the threaded rod 71, and then the up and down position adjustment can be completed, and the adjustment is convenient and fast.

[0044] Cutting members 8, there are two of them, and the two cutting members 8 are respectively fixedly installed on one side of the two mounting assemblies 7 close to each other. The cutting member 8 is composed of a cutting edge portion 81 and a spreading portion 82, and the upper and lower portions of the spreading portion 82 are both inclined surfaces.

[0045] On the left sides of both of the two assembly boxes 2, a second moving block 49 is fixedly installed. On the front inner wall of the first installation groove 11, a first bidirectional threaded rod 491 is rotationally assembled. The rear end of the first bidirectional threaded rod 491 sequentially passes through the two second moving blocks 49 and extends out of the base 1. A first wrench 492 is fixedly installed at the rear end of the first bidirectional threaded rod 491. The front second moving block 49 is threadedly connected to the positive thread section of the first bidirectional threaded rod 491, and the rear second moving block 49 is threadedly connected to the reverse thread section of the first bidirectional threaded rod 491.

[0046] During use, according to different cable diameters, adjust the two circular blocks 32 at the rear side and the two circular blocks 32 at the front side to move closer to and away from each other. When adjusting, rotate the first wrench 492. The first wrench 492 can drive the first bidirectional threaded rod 491 to rotate. Then, through the threaded connection between the two second moving blocks 49 and the first bidirectional threaded rod 491, drive the two second moving blocks 49 to move closer to or away from each other, and then adjust the positions of the four circular blocks 32. Since the four gears 41 are respectively meshed with the two tooth columns 43, and the tooth columns 43 have a certain length, when the positions of the four gears 41 move back and forth, it will not affect the meshing between the tooth columns 43 and the gears 41.

[0047] The usage method of this device is as follows:

[0048] During use, first, according to the diameter of the cable, adjust the two circular blocks 32 on the front and rear sides to move closer to or away from each other, and adjust the two first moving blocks 5 to move closer to and away from each other through the adjustment component to adjust the relative positions of the two cutting members 8. Finally, rotate the threaded rod 71 to adjust the two cutting members 8 to move up and down to be opposite to the center of the cable. The distance between the two cutting members 8 needs to be adjusted to match the inner core diameter of the cable. When cutting the cable, send one end of the cable between the four circular blocks 32. The arc-shaped meshing teeth 33 provided on the four circular blocks 32 can be inserted into the outer plastic layer of the cable and generate a driving force to push the cable to move to the two cutting members 8. When the cable contacts the cutting members 8, the cutting edges of the cutting members 8 first synchronously cut the front and rear sides of the cable. As the cable advances, the cable contacts the spreading part 82 of the cutting members 8. The spreading part 82 separates the upper and lower parts of the outer plastic layer of the cable, and the inner core of the cable is transmitted through between the two cutting members 8. Thus, the separation of the outer plastic layer and the inner core of the cable is realized, without the need for external operation by the staff, which can effectively improve the work efficiency of the staff and has strong applicability.
