[0020] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0021] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0022] This embodiment discloses Figures 1 to 5 The cable stripping device shown in the figure is used for cable production, including a cable stripping box 1, a top cover 2 is installed on the top surface of the cable stripping box 1, and a rectangular opening 4 is opened on the top surface of the top cover 2, and the top surface of the top cover 2 is also provided with a cutting and stripping blade 16 that is lifted and extended from the rectangular opening 4 into the cable stripping box 1 for cutting and stripping the cable 9, and an inverted U-shaped fixing plate 3 is installed above the rectangular opening 4 and on the top surface of the top cover 2, and a plurality of electric lifting rods 14 are symmetrically installed longitudinally on the bottom surface of the U-shaped fixing plate 3, and the electric lifting rods 14 are lifted and lowered in the rectangular opening 4, and an inverted U-shaped blade plate 15 is fixedly installed on the bottom free end of the electric lifting rod 14, and the cutting and stripping blade 16 is rotatably installed in the U-shaped blade plate 15.

[0023] Specifically, the cable 9 is input into the cable stripping box 1 from the rear of the cable stripping box 1, and the U-shaped blade plate 15 is driven down by the electric lifting rod 14 to extend into the rectangular opening 4. The outside of the U-shaped blade plate 15 is provided with a motor (not shown in the figure) for driving the cutting and stripping blade 16 to rotate. After driving the cutting and stripping blade 16 to rotate, the cable 9 is cut and the sheath is opened, so that the cable 9 is output from the cable output port 22, so that the cable core of the cable 9 is wound up, and the sheath is pulled off.

[0024] Specifically, a discharge port 6 is provided on one side outer wall of the cable stripping box 1, and a transverse movement component for reciprocating transverse movement and winding of the cable 9 is slidably connected in the discharge port 6. The transverse movement component includes a transverse movement box body 8 slidably connected in the discharge port 6 and a plurality of cable output ports 22 for outputting the cable 9 that are equidistantly arranged in the transverse movement box body 8. A transverse movement guide rail 24 is fixedly installed on one side of the discharge port 6 and on the inner wall of the cable stripping box 1. A transverse movement guide block 23 that is adapted for sliding connection with the transverse movement guide rail 24 is fixedly installed on the bottom surface of one end of the transverse movement box body 8 located in the inner cavity of the cable stripping box 1.

[0025] Specifically, the cooperation between the transverse guide block 23 and the transverse guide rail 24 in the cable stripping device for cable production not only enables the reciprocating movement of the transverse cassette 8, driving the cable 9 to be evenly reeled on the reeling wheel 12, but also ensures a stable and controlled motion trajectory of the transverse cassette 8, helping to maintain constant tension on the cable 9 during the reeling process, thereby avoiding problems such as uneven cable tension, uneven reeling, and even breakage caused by tension fluctuations. Constant tension also helps maintain the integrity of the cable 9's internal structure, preventing performance degradation caused by excessive stretching or relaxation.

[0026] Specifically, a U-shaped bracket 5 is installed on one side of the discharge port 6 and on the outer wall of the cable stripping box 1. A cable winding assembly for winding the cable 9 is arranged inside the U-shaped bracket 5. The cable winding assembly includes a winding shaft 11 rotatably installed through a bearing 10 inside the U-shaped bracket 5 and a plurality of winding wheel components 12 for winding the cable 9 that are equidistantly interference fit on the circumferential side of the winding shaft 11. A servo motor 13 for driving the winding shaft 11 is installed on the outer wall of one side of the U-shaped bracket 5.

[0027] Specifically, the servo motor 13 drives the reel 11 to rotate in the U-shaped bracket 5, and drives multiple reel components 12 to rotate synchronously while being able to wind and reel the cable core. Through the precise cooperation between the transverse guide block component 23 and the transverse guide rail component 24, the moving direction and speed of the transverse box body 8 can be precisely controlled, which can ensure that the cable 9 always enters the reel component 12 along the predetermined path during the reeling process, effectively preventing the cable 9 from being kinked, knotted or cross-wound during the reeling process, and ensuring that the cable coil is regular after reeling and easy to handle and use later.

[0028] Specifically, the upper and lower sides of the discharge port 6 and the outer wall of the cable stripping box 1 are provided with relatively movable stripping knife pieces 19 for stripping the cable skin off the cable 9, and the upper and lower sides of the discharge port 6 and the outer wall of the cable stripping box 1 are symmetrically welded with fixed cross plates 7, and the two fixed cross plates 7 are symmetrically installed with limited U-shaped card blocks 17 on the opposite side and on the outer wall of the cable stripping box 1. The two relatively arranged stripping knife pieces 19 are limitedly passed through in each limited U-shaped card block 17, and the two stripping knife pieces 19 are installed on the opposite side of each other. An electric push-pull rod 20, and the tail end of the electric push-pull rod 20 is installed on the inner wall of the fixed horizontal plate 7 for pushing and pulling the stripping knife 19 to move in the limiting U-shaped block 17 to clamp the cable 9 and strip the skin. The two stripping knife members 19 are provided with sharp stripping ends 18 for stripping the cable 9 at opposite ends. The two sharp stripping ends 18 are both centripetally facing the cable 9. A plurality of arc-shaped stripping bayonet slots 21 are equidistantly provided at the opposite end of each sharp stripping end 18. The two arc-shaped stripping bayonet slots 21 arranged opposite to each other up and down are both centripetally clamped on the outer wall of the cable core of the cable 9.

[0029] Specifically, the stripping blade 19 is controlled by an electric push-pull rod 20 and moves within the limiting U-shaped clamp 17. It can adapt to the diameter and shape of the cable 9 to form a precise clamping force on the cable. This clamping force not only ensures the stable fixation of the cable, preventing it from sliding or shifting during the stripping process, but also ensures that the stripping action is accurately applied at the boundary between the cable sheath and the cable core.

[0030] Specifically, the curved stripping tab 21 is designed to fit snugly against the outer wall of the cable core. Its curved profile conforms to the circular cross-section of the cable, ensuring evenly distributed pressure on the cable sheath throughout the stripping process. This uniform pressure helps prevent damage to the cable core caused by excessive localized pressure, while also preventing incomplete stripping due to insufficient pressure, thereby improving stripping quality.

[0031] Specifically, the sharp stripping end 18 of the stripping knife 19 works together with the arc-shaped stripping bayonet 21, and uses a clamping method to imitate the action of manually stripping the sheath, and quickly and continuously strips the cable sheath through continuous friction and shear force. Compared with a single cutting or tearing method, this method is more conducive to achieving a quick and clean separation of the cable sheath and the cable core, and significantly improves the stripping efficiency.

[0032] Specifically, the multiple equidistant settings of the arc-shaped stripping bayonet 21 increase the contact points with the cable sheath, which can more effectively prevent the cable sheath from being locally wrinkled, twisted or adhered to the cable core during the stripping process. Especially when dealing with cable sheaths with uneven thickness, soft material or sticky material, the arc-shaped stripping bayonet 21 can ensure that the cable sheath is stripped evenly and continuously, reducing subsequent cleaning work.

[0033] Specifically, the inner cavity of the cable stripping box 1 is provided with a PLC for opening and closing control of various devices. The PLC model can be selected according to actual needs. In the present invention, the PLC model is S7-200, which has the advantages of high reliability, strong anti-interference ability and easy maintenance.

[0034] How it works The cable stripping device for cable production comprises a cable 9 fed into the cable stripping box 1 from the rear thereof, a U-shaped blade plate 15 driven by an electric lift rod 14 to descend and extend into a rectangular opening 4, and a motor (not shown) provided on the outside of the U-shaped blade plate 15 for driving a cutting and stripping blade 16 to rotate. The cutting and stripping blade 16 is driven to rotate to cut and separate the sheath of the cable 9, and the cable 9 is then output from a cable outlet 22. The servo motor 13 drives the reel 11 to rotate in the U-shaped bracket 5, and drives the multiple reel members 12 to rotate synchronously, so as to wind and reel the cable core. The precise coordination between the transverse guide block 23 and the transverse guide rail 24 allows the moving direction and speed of the transverse box 8 to be precisely controlled, ensuring that the cable 9 always enters the reel member 12 along the predetermined path during the reeling process, thereby preventing the cable 9 from being kinked, knotted or cross-entangled during the reeling process. The stripping knife 19 is controlled by the electric push-pull rod 20 and moves in the limiting U-shaped block 17. The design of the arc-shaped stripping bayonet 21 enables it to fit tightly against the outer wall of the cable core, and its arc-shaped contour can conform to the circular cross-section of the cable. The sharp stripping end 18 of the stripping knife 19 works together with the arc-shaped stripping bayonet 21, and uses a clamping method to imitate the action of manually stripping off the sheath, and through continuous friction and shear force, the cable sheath is quickly and continuously stripped.
