Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, specifically to a precision cable-forming machine for wires and cables. Background Technology

[0002] Cable forming machines are key equipment in wire and cable factories manufacturing power cables, plastic-insulated cables, and rubber-insulated cables. They are suitable for cabling and armoring multi-core rubber-insulated cables, plastic-insulated cables, cross-linked cables, telephone cables, and control cables of various cross-sections. Their design integrates the advantages of advanced cable forming equipment from both domestic and international sources, and closely aligns with the actual needs of wire and cable production in my country. Primarily targeting the production and armoring processes of four-core and five-core plastic-insulated and cross-linked cables with cross-sectional areas of 25-240 mm², they provide a professional and efficient complete solution for wire and cable production.

[0003] Currently, various methods have been proposed for precision cable winding machines for wires and cables in existing technologies. For example, a patent application with publication number "CN220976097U" discloses a winding machine for wires and cables. A rotating motor drives a rotating shaft, which in turn drives a connecting shaft. The connecting shaft rotates to wind the wires and cables. If the winding width needs to be adjusted, two limiting discs are rotated, causing the threaded ring to rotate on the threaded ring, changing the distance between the two limiting discs and thus changing the winding width. However, the wires and cables are always fixed at the same position on the connecting shaft during winding. As winding progresses, more and more wires and cables accumulate at this position, leading to uneven winding. This can cause the cable to form irregular shapes such as towers or flattened shapes on the winding reel, affecting the winding quality and subsequent use, transportation, and storage. Furthermore, if a recently used cable is completely wound together, the internal heat is difficult to dissipate, easily leading to excessively high cable temperatures. Prolonged exposure to high temperatures accelerates the aging of the cable insulation material, reducing the cable's insulation performance and service life, posing a safety hazard.

[0004] Therefore, this utility model provides a precision cable-making machine for wires and cables. Utility Model Content

[0007] Preferably, the limiting mechanism includes a guide rod, which is fixedly installed between the side walls of the two second fixing plates, and the nut slides on the guide rod, with the guide rod passing through the nut.

[0008] Preferably, the adjusting mechanism includes a spring and a pressure plate, the side wall of the cable trough is provided with a sliding groove, one end of the spring is fixedly installed on the inner upper wall of the cable box, the other end of the spring is fixedly installed on the upper end of the pressure plate, and the pressure plate slides in the sliding groove.

[0009] Preferably, the drive mechanism includes a first synchronous pulley, a belt, and a second synchronous pulley. The first synchronous pulley is rotatably mounted on the side wall of the first fixed plate and is fixedly connected to the take-up roller via a short rod. The second synchronous pulley is rotatably mounted on the side wall of the second fixed plate. The reciprocating screw passes through the second fixed plate and is fixedly connected to the second synchronous pulley. The belt is located on the same side as the first and second synchronous pulleys.

[0010] Preferably, the cooling mechanism includes a stopper cylinder, a first crank, and a piston. The stopper cylinder is fixedly installed on the upper end of the base. The stopper cylinder is connected to a water tank via a water inlet pipe. The water tank is fixedly installed on the upper end of the base. A water outlet pipe is connected to the side wall of the stopper cylinder. The end of the water outlet pipe away from the stopper cylinder is fixedly installed on the side wall of the reciprocating screw. The piston slides inside the stopper cylinder. The first crank is fixedly installed on the upper end of the piston and passes through the sliding stopper cylinder. A moving mechanism for moving the first crank is installed on the second fixed plate.

[0011] Preferably, the moving mechanism includes a turntable and a second crank. The turntable is rotatably mounted on the side wall of the second fixed plate. The reciprocating screw passes through the second fixed plate and is fixedly connected to the center point of the turntable. One end of the second crank is rotatably mounted on the upper end of the turntable, and the other end of the second crank is rotatably mounted on the first crank.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The precision cable winding machine of this utility model involves passing the cable through a cable groove, connecting one end of the cable to a winding roller. A motor is started, driving the winding roller to rotate, which in turn causes the winding roller to wind the cable. Under the action of the drive mechanism, a reciprocating screw rotates, causing the nut to move reciprocally along the guide rod. This causes the cable box to move the cable reciprocally along the winding roller, ensuring the cable is evenly distributed axially on the winding roller. This avoids the uneven winding problem caused by the cable always piling up at the same position on the connecting shaft, effectively preventing the formation of irregular shapes such as towers or flat shapes, and improving the winding quality of the cable. Simultaneously, it avoids the internal heat dissipation difficulties caused by excessive cable piling, which helps to reduce the temperature of the cable during the winding process.

[0018] 2. The precision cable winding machine of this utility model, during cable winding, uses a reciprocating screw to drive a turntable to rotate, which in turn drives a second crank to move up and down reciprocally. The second crank, through the first crank, drives a piston to move up and down reciprocally within a stopper cylinder. This allows cooling water from the water tank to enter the stopper cylinder through the inlet pipe and then spray water onto the surface of the cable through the outlet pipe, achieving continuous cooling of the cable. This effectively avoids problems such as accelerated aging of insulation materials caused by local overheating of the cable during winding, and significantly improves the service life of the cable.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0026] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1 to 4 As shown in the embodiment of this utility model, a precision cable forming machine for wires and cables includes a base 1. Two first fixing plates 2 are fixedly connected to the upper end of the base 1. A winding roller 4 is rotatably connected to the side wall of the first fixing plate 2. Two limiting discs 3 are fixedly connected to the winding roller 4. Two second fixing plates 5 are fixedly connected to the upper end of the base 1. A reciprocating screw 9 is rotatably connected between the side walls of the two second fixing plates 5. The limiting discs 3 are connected to the reciprocating screw 9 through a driving mechanism. A nut 7 is threaded onto the reciprocating screw 9. A limiting mechanism for limiting the nut 7 is installed on the second fixing plate 5. A cable box 6 is fixedly connected to the upper end of the nut 7. A cable groove 22 is opened on the side wall of the cable box 6. An adjusting mechanism for adjusting the size of the cable groove 22 is installed on the side wall of the cable box 6. A cooling mechanism for cooling the cable is installed on the upper end of the base 1.

[0032] like Figure 1 As shown, the limiting mechanism includes a guide rod 8, which is fixedly installed between the side walls of the two second fixed plates 5. The nut 7 slides on the guide rod 8, and the guide rod 8 passes through the nut 7. This structure provides precise guidance and stable support for the reciprocating movement of the nut 7, effectively preventing the nut 7 from shaking or shifting during movement. This ensures the accurate movement trajectory of the cable box 6, thereby guaranteeing that the cable is wound evenly and neatly on the winding roller 4, improving the regularity and tightness of the cable winding.

[0033] like Figure 3 As shown, the adjusting mechanism includes a spring 19 and a pressure plate 20. A sliding groove 21 is provided on the side wall of the cable trough 22. One end of the spring 19 is fixedly installed on the inner upper wall of the cable box 6, and the other end of the spring 19 is fixedly installed on the upper end of the pressure plate 20. The pressure plate 20 slides within the sliding groove 21. This structure allows for convenient and quick adjustment of the size of the cable trough 22 according to the diameter of the cable. This design is not only simple to operate but also ensures that the cable is stably placed within the cable trough 22 during the winding process.

[0034] like Figure 2As shown, the drive mechanism includes a first synchronous pulley 16, a belt 17, and a second synchronous pulley 18. The first synchronous pulley 16 is rotatably mounted on the side wall of the first fixed plate 2 and is fixedly connected to the take-up roller 4 via a short rod. The second synchronous pulley 18 is rotatably mounted on the side wall of the second fixed plate 5. The reciprocating screw 9 passes through the second fixed plate 5 and is fixedly connected to the second synchronous pulley 18. The belt 17 is located on the same side as the first synchronous pulley 16 and the second synchronous pulley 18. During operation, when the take-up roller 4 rotates, the first synchronous pulley 16 rotates accordingly, driving the second synchronous pulley 18 to rotate via the belt 17. This transmission method has a simple and compact structure, runs smoothly and reliably, and can ensure the coordination of the winding action and the reciprocating movement, improving the overall operating efficiency and stability of the equipment.

[0035] like Figure 1 and Figure 4 As shown, the cooling mechanism includes a stopper cylinder 13, a first crank 23, and a piston 24. The stopper cylinder 13 is fixedly installed on the upper end of the base 1. The stopper cylinder 13 is connected to a water tank 11 via a water inlet pipe 12. The water tank 11 is fixedly installed on the upper end of the base 1. A water outlet pipe 14 is connected to the side wall of the stopper cylinder 13. The end of the water outlet pipe 14 away from the stopper cylinder 13 is fixedly installed on the side wall of the reciprocating screw 9. The piston 24 slides inside the stopper cylinder 13. The first crank 23 is fixedly installed on the upper end of the piston 24 and passes through the sliding stopper cylinder 13. A moving mechanism for moving the first crank 23 is installed on the second fixed plate 5. During operation, the piston 24 moves up and down reciprocally inside the stopper cylinder 13, causing the cooling water in the water tank 11 to enter the stopper cylinder 13 sequentially through the water inlet pipe 12, and then be evenly sprayed onto the cable surface through the water outlet pipe 14. The aforementioned structure ensures that cooling water is evenly sprayed onto the cable surface, effectively cooling the cable and preventing performance degradation and safety hazards caused by localized overheating during the winding process. Furthermore, this cooling mechanism operates synchronously with the winding mechanism, eliminating the need for an additional power source, reducing equipment energy consumption and complexity, and improving production efficiency and cable quality stability.

[0036] like Figure 1As shown, the moving mechanism includes a turntable 10 and a second crank 25. The turntable 10 is rotatably mounted on the side wall of the second fixed plate 5. The reciprocating screw 9 passes through the second fixed plate 5 and is fixedly connected to the center point of the turntable 10. One end of the second crank 25 is rotatably mounted on the upper end of the turntable 10, and the other end is rotatably mounted on the first crank 23. The rotation of the turntable 10 drives the second crank 25 to move up and down reciprocally. Through the connection between the second crank 25 and the first crank 23, the reciprocating movement is transmitted to the piston 24, realizing the precise reciprocating motion of the piston 24 within the cylinder 13. It should be noted that the second crank 25 is rotatably mounted on the turntable 10 at a position off-center. When the turntable 10 rotates around its central axis, because the second crank 25 is located off-center, its distance relative to the central axis will change periodically, thereby driving the connected components such as the piston 24 to move up and down reciprocally.

[0037] like Figure 1 As shown, one-way valves are installed in the inlet pipe 12 and the outlet pipe 14. During operation, when the piston 24 moves upward, the one-way valve in the inlet pipe 12 opens, and the one-way valve in the outlet pipe 14 closes, allowing the cooling water in the water tank 11 to flow only through the inlet pipe 12 into the stopper cylinder 13, thus causing the cooling water in the water tank 11 to sequentially enter the stopper cylinder 13 through the inlet pipe 12. When the piston 24 moves downward, the one-way valve in the inlet pipe 12 closes, and the one-way valve in the outlet pipe 14 opens, allowing the cooling water in the stopper cylinder 13 to be discharged only through 14. Through the above structure, the installation of one-way valves in the inlet pipe 12 and the outlet pipe 14 effectively prevents the backflow of cooling water during the transportation process. This ensures that the cooling water can flow along a predetermined path, sequentially passing from the water tank 11 through the inlet pipe 12, the stopper cylinder 13, and the outlet pipe 14, and finally being evenly sprayed onto the cable surface.

[0038] like Figure 1 As shown, the water outlet pipe 14 is a retractable water pipe. This structure allows for adaptation to changes in component positions during equipment operation, especially when the cable box 6 drives the cable to reciprocate along the winding roller 4, ensuring a stable relative position between the water outlet pipe 14 and the cable, and guaranteeing that cooling water can be accurately sprayed onto the cable surface.

[0039] like Figure 3 As shown, the lower end of the pressure plate 20 is made of rubber. Through this structure, the rubber material has a certain degree of elasticity, which can provide cushioning and protection for the cable surface, preventing damage to the cable sheath due to hard friction, and improving the cable's quality and appearance integrity.

[0040] like Figure 1 As shown, a motor 15 is fixedly connected to the side wall of the first fixed plate 2, and the output shaft of the motor 15 is fixedly connected to the take-up roller 4. During operation, after the motor 15 starts, it drives the take-up roller 4 to rotate.

[0041] Working principle: First, the cable is passed through the cable groove 22 on the side wall of the cable box 6, and one end of the cable is connected to the take-up roller 4. After the motor 15 starts, it drives the take-up roller 4 to rotate, thereby causing the cable to begin winding. During this process, when the take-up roller 4 rotates, the first synchronous pulley 16 rotates accordingly, driving the second synchronous pulley 18 to rotate via the belt 17. The second synchronous pulley 18 is fixedly connected to the reciprocating screw 9, causing the reciprocating screw 9 to rotate. The rotation of the reciprocating screw 9 drives the nut 7 to reciprocate along the guide rod 8 through the threaded connection, thereby causing the cable box 6 to move the cable reciprocally along the take-up roller 4, ensuring that the cable can be wound evenly on the surface of the take-up roller 4.

[0042] Simultaneously, the reciprocating screw 9 drives the turntable 10 to rotate, and the rotation of the turntable 10 causes the second crank 25 to move up and down reciprocally. The second crank 25 drives the piston 24 to move up and down reciprocally within the plug cylinder 13 via the first crank 23. When the piston 24 moves upward, under the action of the one-way valve in the water inlet pipe 12, the cooling water in the water tank 11 can only flow into the plug cylinder 13 through the water inlet pipe 12, thereby causing the cooling water in the water tank 11 to enter the plug cylinder 13 sequentially through the water inlet pipe 12. When the piston 24 moves downward, under the action of the one-way valve in 14, the cooling water in the plug cylinder 13 can only be discharged through 14, so that the water outlet pipe 14 sprays evenly onto the cable surface, achieving effective cooling of the cable during the winding process.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
