Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a stripping device for cable production. Background Technology

[0002] Cable stripping equipment is a widely used processing method in cable production, primarily relying on manual or semi-automatic mechanical devices to remove the outer insulation sheath of the cable. This technology typically uses wire pullers, scissors, or simple gear-driven equipment to cut or tear the insulation layer through mechanical force. Its advantages include simple operation and low cost, but it is relatively slow, labor-intensive, and requires a high level of skill from the operators.

[0003] Traditional mechanical stripping techniques face significant technical challenges when processing multi-layered insulated or small-diameter cables. Insufficient blade control precision makes it difficult to adapt to variations in insulation layer thickness and material, especially with multi-layered insulated cables where differences in material and thickness further complicate control. Even experienced operators struggle to completely avoid errors during operation, making real-time adjustment of blade position and pressure particularly difficult. This often results in the blade cutting too deeply, damaging the internal conductors and affecting the cable's conductivity and mechanical strength; or cutting too shallowly, leading to incomplete stripping and requiring secondary processing, increasing costs and time. Conductor damage directly results in unstable cable quality, increasing susceptibility to malfunctions. Furthermore, the need for manual inspection and repair reduces production efficiency. Utility Model Content

[0004] Therefore, it is necessary to address the issues of excessive blade penetration damaging the internal wire core, affecting the cable's conductivity and mechanical strength, or insufficient penetration resulting in incomplete stripping and requiring secondary processing, which increases cost and time. Wire core damage directly leads to unstable cable quality and is prone to failure. Furthermore, the need for manual inspection and repair reduces production efficiency. This paper proposes a cable stripping device.

[0005] A cable stripping device includes: a base plate, two supports fixedly connected above the base plate, a crossbar fixedly connected between the two supports, a control block threaded into the inside of the crossbar, a knife holder provided at the lower end of the control block, and a cutting blade provided inside the knife holder;

[0006] The second transmission wheel is movably disposed inside the two brackets. A motor is fixedly connected to the outer wall of one of the brackets. The output end of the motor is driven by a coupling to one end of the second transmission wheel.

[0007] The pressure block is movably fitted onto the surface of the tool holder, and support components are provided on both sides of the pressure block.

[0008] In one embodiment, a first drive wheel is movably inserted into the interior of the two brackets, the first drive wheel being located on one side of the second drive wheel.

[0009] In one embodiment, both the first drive wheel and the second drive wheel have guide grooves on their surfaces, and the guide grooves of both the first drive wheel and the second drive wheel extend obliquely to both sides.

[0010] In one embodiment, the blade holder slides inside the lower pressure block, and the cutting blade moves above the second drive wheel.

[0011] In one embodiment, the control block stands vertically above the tool holder, and a bearing ring is installed at the connection between the tool holder and the control block.

[0012] In one embodiment, a guide groove is provided below the pressing block, and the cutting blade is located inside the guide groove and extends downward.

[0013] In one embodiment, the support assembly includes connecting rods fixed to both sides of the lower pressure block, one end of each of the two connecting rods is fixedly connected to a support block, the two support blocks are respectively slidably located inside the two brackets, and threaded shafts are threadedly inserted into the interior of the two brackets, the lower ends of the two threaded shafts are movably connected to the support blocks.

[0014] Beneficial effects

[0015] 1. Rotating the threaded shaft adjusts the height of the support blocks. The two support blocks adjust the position of the lower pressure block. Rotating the control block adjusts the height of the tool holder. The motor drives the second transmission wheel to rotate, which pushes the cable, causing it to move between the second transmission wheel and the lower pressure block. During the movement, the cable comes into contact with the cutting blade. By adjusting the distance between the lower pressure block and the second transmission wheel, cables of different diameters can be transported. By adjusting the extension length of the cutting blade inside the lower pressure block, cables of different diameters can be cut, thus improving the accuracy and efficiency of cable cutting.

[0016] 2. The guide grooves in the middle of the first and second transmission wheels are V-shaped grooves. The inclined surface of the guide grooves can guide the cable, allowing the cable to move within the guide grooves. Multiple friction blocks are installed inside the guide grooves of the first and second transmission wheels. These friction blocks are arranged in a ring on the surface of the first and second transmission wheels. The friction blocks increase the friction between the first and second transmission wheels and the cable, improving the stability of cable transmission. The tool holder has two fixing holes inside, through which the cutting blade is fixed. The tool holder and the cutting blade are detachably connected, allowing for quick replacement of the cutting blade. The cutting blade extends upwards at an angle towards the cable, and its cutting surface has a certain slope, improving the sharpness of cutting the cable sheath. The bearing ring installed between the tool holder and the control block reduces friction and improves the stability of the tool holder support. Attached Figure Description

[0029] The following is combined with Figures 1-4 This invention describes a cable stripping device for cable production.

[0030] In one embodiment, a cable stripping device includes: a base plate 100, a second drive wheel 300, and a lower pressure block 500. Two supports 101 are fixedly connected to the top of the base plate 100, and a crossbar 102 is fixedly connected between the two supports 101. A control block 503 is threaded into the crossbar 102. A knife holder 501 is provided at the lower end of the control block 503. A cutting blade 502 is provided inside the knife holder 501. The second drive wheel 300 is movably disposed inside the two supports 101. A motor 301 is fixedly connected to the outer wall of one of the supports 101. The output end of the motor 301 is drivenly connected to one end of the second drive wheel 300 through a coupling. The lower pressure block 500 is movably sleeved on the surface of the knife holder 501. Support components 400 are provided on both sides of the lower pressure block 500.

[0031] In this embodiment, two supports 101 are erected on the base plate 100 to support the crossbar 102. The rotation control block 503 drives the lower threaded rod to adjust the blade holder 501 to slide inside the lower pressure block 500, and adjust the cutting blade 502 installed inside the blade holder 501 to extend downward. The support assembly 400 fixes the lower pressure block 500 so as to adjust the height of the lower pressure block 500 and improve the stability of the blade holder 501 in cutting the cable.

[0032] Motor 301 drives the second transmission wheel 300 to rotate. The second transmission wheel 300 and the cutter holder 501 form a cable channel, allowing the cable to move. When the cable passes between the cutter holder 501 and the second transmission wheel 300, the cable sheath will come into contact with the cutting disc 502. The cutting disc 502 will cut the cable from below, improving the cable cutting efficiency and cutting stability.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a first transmission wheel 200 is movably inserted into the interior of the two brackets 101. The first transmission wheel 200 is located on one side of the second transmission wheel 300. Guide grooves are provided on the surfaces of both the first transmission wheel 200 and the second transmission wheel 300. The guide grooves of the first transmission wheel 200 and the second transmission wheel 300 extend inclined to both sides.

[0034] In this embodiment, the guide groove in the middle of the first transmission wheel 200 and the second transmission wheel 300 is a V-shaped groove. The inclined surface of the guide groove can guide the cable, allowing the cable to move inside the guide groove. Multiple friction blocks are installed inside the guide groove of the first transmission wheel 200 and the second transmission wheel 300. The multiple friction blocks are arranged in a ring on the surface of the first transmission wheel 200 and the second transmission wheel 300. The friction blocks increase the friction between the first transmission wheel 200 and the second transmission wheel 300 and the cable, thereby improving the stability of cable transmission.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the tool holder 501 slides inside the lower pressure block 500, the cutting blade 502 moves above the second transmission wheel 300, the control block 503 stands vertically above the tool holder 501, a bearing ring is installed at the connection between the tool holder 501 and the control block 503, a guide groove is provided below the lower pressure block 500, and the cutting blade 502 is located inside the guide groove and extends downward.

[0036] In this embodiment, the blade holder 501 has two fixing holes inside, through which the cutting blade 502 is fixed. The detachable connection between the blade holder 501 and the cutting blade 502 allows for quick replacement of the cutting blade 502. The cutting blade 502 extends upward at an angle towards the cable, and its cutting surface has a certain slope to improve the cutting sharpness of the cable sheath. The bearing ring installed between the blade holder 501 and the control block 503 reduces friction and improves the stability of the blade holder 501.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the support assembly 400 includes connecting rods 401 fixed on both sides of the lower pressure block 500. One end of each connecting rod 401 is fixedly connected to a support block 403. The two support blocks 403 are respectively located inside the two brackets 101 and slide. Threaded shafts 402 are threaded into the interior of the two brackets 101. The lower ends of the two threaded shafts 402 are movably connected to the support blocks 403.

[0038] In this embodiment, the connecting rod 401 fixes the lower pressure block 500, and the two support blocks 403 slide inside the bracket 101. The rotating threaded shaft 402 controls the lifting and lowering of the support blocks 403, which is used to control the lifting and lowering of the lower pressure block 500. By adjusting the distance between the lower pressure block 500 and the second transmission wheel 300, it is convenient to cut cables of different diameters, thereby improving the cable cutting efficiency.

[0039] Working principle:

[0040] Rotating the threaded shaft 402 adjusts the height of the support block 403. The two support blocks 403 adjust the position of the lower pressure block 500. Rotating the control block 503 adjusts the height of the tool holder 501. The motor 301 drives the second transmission wheel 300 to rotate, and the second transmission wheel 300 pushes the cable, causing the cable to move between the second transmission wheel 300 and the lower pressure block 500. During the movement, the cable will contact the cutting blade 502. By adjusting the distance between the lower pressure block 500 and the second transmission wheel 300, cables of different diameters can be transported. By adjusting the extension length of the cutting blade 502 inside the lower pressure block 500, cables of different diameters can be cut, improving the accuracy and efficiency of cable cutting.

[0041] It should be noted that the motor 301 and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. In addition, the motor 301 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
