Description

Technical Field

[0001] This application relates to the field of wire and cable production equipment technology, and in particular to a winding device for low-smoke halogen-free irradiated wires and cables. Background Technology

[0002] Low-smoke halogen-free irradiated wires and cables have excellent properties such as low smoke, halogen-free, and flame retardant, and are widely used in construction, rail transportation, shipbuilding and other fields. In the production process of low-smoke halogen-free irradiated wires and cables, winding is a crucial process, and the winding quality directly affects the subsequent storage, transportation and use of the cable.

[0003] Currently, existing wire and cable winding devices have several shortcomings when winding low-smoke halogen-free irradiated wires and cables. On the one hand, the fixing method of the winding rollers is relatively complex, and the replacement process of the winding rollers is cumbersome and has poor adaptability when different specifications of cables need to be wound. On the other hand, there is a lack of an effective cable laying mechanism during the winding process, which can easily lead to messy cable laying and irregular winding, affecting subsequent use. In addition, the winding tension cannot be flexibly adjusted according to the cable specifications and winding requirements. Excessive tension can easily cause cable stretching damage, while insufficient tension can easily lead to loose winding. Therefore, a low-smoke halogen-free irradiated wire and cable winding device has been proposed to solve the above problems. Utility Model Content

[0007] The winding mechanism includes a fixed base and a turntable. The fixed base is fixedly connected to the top outer wall of the base plate, and the turntable is rotatably connected to the outer wall of the fixed base. A fixing component is installed on the outer wall of the turntable, and a winding roller is installed on the outer wall of the turntable through the fixing component.

[0008] The fixing assembly includes a fixing cylinder, a sliding cylinder, a first connecting rod, a second connecting rod, and an arc-shaped fixing plate.

[0010] Preferably, the winding mechanism further includes a servo motor, a main gear, and a secondary gear. The servo motor is fixedly mounted on the outer wall of the fixed base, and its output end passes through the fixed base and is fixedly connected to the main gear. The secondary gear is fixedly connected to the outer wall of the turntable on the side away from the fixed cylinder, and the main gear and the secondary gear mesh with each other.

[0011] Preferably, the cable guide assembly includes a reciprocating lead screw and a cable guide wheel. The two ends of the reciprocating lead screw are fixedly connected to the top outer wall of the base plate through two bearing seats, and the cable guide wheel is threadedly connected to the outer wall of the reciprocating lead screw.

[0012] Preferably, the tensioning assembly includes columns, a tensioning shaft, and a tensioning wheel. The two columns are fixedly connected to the top outer wall of the base plate, the two ends of the tensioning shaft are located inside the two columns, and the tensioning wheel is movably connected to the outer wall of the tensioning shaft.

[0013] Preferably, the tensioning assembly further includes a slider, a slide rod, and a spring.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. The fixing assembly adopts a scissor-type telescopic structure. Driven by an electric cylinder, the sliding cylinder allows for radial expansion and contraction of the arc-shaped fixing plate, quickly completing the installation and removal of the take-up roller. This structure requires no complex operation, can adapt to take-up rollers of different inner diameters, and meets the winding requirements of various specifications of low-smoke halogen-free irradiated wires and cables, significantly improving the adaptability and operational efficiency of the device.

[0016] 2. A cable laying assembly consisting of a reciprocating screw and a cable laying wheel is provided. The cable laying wheel moves back and forth along the reciprocating screw, which is parallel to the axis of the take-up roller. This guides the cable to be evenly laid out along the axis of the take-up roller. This screw-driven cable laying method can accurately control the winding position of the cable, completely solve the problem of messy cable laying, ensure neat winding, and provide convenience for the subsequent storage, transportation and use of the cable.

[0017] 3. A spring-type tensioning assembly is adopted, which drives the tensioning wheel to adaptively adjust its position through the elastic deformation of the spring, balancing the tension in real time during the winding process. When the cable tension is too high, the spring compression buffers the tension to prevent the cable from being stretched and damaged; when the tension is too low, the spring rebounds to provide tension force to prevent the winding from becoming loose, effectively ensuring the winding quality of low-smoke halogen-free irradiated wires and cables.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a low-smoke halogen-free irradiated wire and cable winding device. (Refer to...) Figure 1-4 The low-smoke halogen-free irradiated wire and cable winding device includes a base plate 1. Along the direction of cable winding, the top outer wall of the base plate 1 is equipped with a cable laying assembly, a tensioning assembly, and a winding mechanism from left to right. The three work together to realize the functions of neat cable laying, tension adjustment, and winding and storage during the cable winding process. The overall structure is compact and the transmission connection is smooth.

[0025] The winding mechanism is the core execution unit for realizing cable winding. It consists of a fixed base 11, a turntable 12, a servo motor 14, a main gear 15, a secondary gear 13, a fixed assembly, and a winding roller 23.

[0026] The fixed base 11 is bolted to the top outer wall of the base plate 1, providing stable support for the entire winding mechanism. The turntable 12 is rotatably connected to the side wall of the fixed base 11 via bearings and can rotate freely around its own axis.

[0027] The servo motor 14 is fixedly mounted on the side wall of the fixed base 11 away from the turntable 12 via a motor bracket. Its output shaft passes through a pre-set shaft hole on the fixed base 11 and is coaxially fixedly connected to the main gear 15. The auxiliary gear 13 is coaxially fixed to the outer wall of the turntable 12 away from the fixed cylinder 16 via a key connection. The main gear 15 and the auxiliary gear 13 mesh with each other to form a gear transmission structure, which transmits the power of the servo motor 14 to the turntable 12.

[0028] A fixing assembly is installed on the outer wall of the center of the turntable 12 to enable quick assembly, disassembly, and fixing of the take-up roller 23. It includes a fixing cylinder 16, a sliding cylinder 20, connecting rod 18, connecting rod 29, an arc-shaped fixing plate 17, a limiting sliding frame 21, and an electric cylinder 22. The fixing cylinder 16 is coaxially arranged with the turntable 12 and fixed to the outer wall of the center of the turntable 12 by welding. The sliding cylinder 20 is sleeved on the outer wall of the fixing cylinder 16, forming an axial sliding fit. The middle sections of connecting rod 18 and connecting rod 29 are hinged to each other by pins, forming a scissor-type telescopic structure. Multiple sets of this scissor structure are evenly distributed along the circumference of the fixing cylinder 16. The bottom ends of multiple connecting rods 29 are hinged to the outer wall of the fixing cylinder 16 via hinge seats, and the bottom ends of multiple connecting rods 18 are hinged to the outer wall of the sliding cylinder 20 via hinge seats. The top ends of multiple connecting rods 18 are correspondingly hinged to the bottom outer walls of multiple arc-shaped fixing plates 17.

[0029] The limiting slide frame 21 is fixedly connected to the bottom outer wall of the arc-shaped fixed plate 17 away from the connecting rod 18, forming a U-shaped closed structure. The top end of the connecting rod 19 is movably connected to the inside of the limiting slide frame 21 through a shaft pin, and can move along the length direction of the limiting slide frame 21, providing guidance for the radial extension and retraction of the arc-shaped fixed plate 17. The electric cylinder 22 is fixedly installed in the internal cavity of the fixed cylinder 16, and its output shaft extends along the axial direction of the fixed cylinder 16. The end of the output shaft is fixedly connected to the inner wall of the slide cylinder 20 through a flange, and is used to drive the slide cylinder 20 to slide axially along the fixed cylinder 16. The take-up roller 23 is sleeved on the outside of multiple arc-shaped fixed plates 17, and is connected to the arc-shaped fixed plates through the outer wall of the arc-shaped fixed plates 17. The radial expansion of 17 achieves fixation with the turntable 12. It should be noted that the inner cavity of the fixing cylinder 16 is connected to the rotating shaft of the turntable 12. The rotating shaft of the turntable 12 has a hollow structure. The connecting cable of the electric cylinder 22 can pass through the inner cavity of the fixing cylinder 16 and the hollow rotating shaft of the turntable 12 and extend to the fixing seat 11. An electric slip ring is installed at the connection position between the fixing seat 11 and the rotating shaft of the turntable 12. The connecting cable is electrically connected to the external power supply and control system through the electric slip ring. This can effectively prevent the connecting cable from getting tangled or pulled during the rotation of the turntable 12, and ensure the stability of the power supply and control signal transmission of the electric cylinder 22. This is existing technology and will not be described in detail.

[0030] The cable guide assembly, used to guide the cable to be evenly distributed along the axial direction of the take-up roller 23, consists of a bearing seat 2, a reciprocating screw 3, and a cable guide wheel 4. Two bearing seats 2 are symmetrically fixed to the top outer wall of the base plate 1. The two ends of the reciprocating screw 3 are rotatably supported on the two bearing seats 2 via bearings, and the axis of the reciprocating screw 3 remains parallel to the axis of the take-up roller 23. The cable guide wheel 4 has a threaded hole at its center that matches the reciprocating screw 3, and is threadedly fitted onto the outer wall of the reciprocating screw 3. An annular groove is formed on the outer circumference of the cable guide wheel 4, the curvature of which matches the outer diameter of the cable, allowing the cable to pass through and providing guidance and restraint.

[0031] The tensioning assembly is used to adjust the tension of the cable during the winding process in real time, preventing damage due to excessive tension or loosening due to insufficient tension. It consists of columns 5, sliders 6, slide rods 7, springs 8, tensioning shafts 9, and tensioning wheels 10. Two columns 5 are symmetrically fixed to the top outer wall of the base plate 1, each with a vertical mounting cavity. Two slide rods 7 are vertically fixed within the mounting cavities of the two columns 5, and sliders 6 are slidably fitted onto the outer wall of slide rods 7, allowing them to move up and down along the axial direction of slide rods 7. The two ends of the tensioning shaft 9 are fixedly connected to the two sliders 6, and the tensioning wheel 10 is rotatably connected to the outer wall of the tensioning shaft 9 via bearings. Its outer circumferential surface has grooves adapted to fit the cable surface. The spring 8 is fitted onto the outer wall of the slide rod 7, located between the slider 6 and the inner bottom of the column 5. The top end of the spring 8 abuts against the bottom of the slider 6, and the bottom end abuts against the inner bottom of the column 5. Through its elastic deformation, the spring 8 provides continuous tension to the tensioning wheel 10.

[0032] The implementation principle of the low-smoke halogen-free irradiated wire and cable winding device in this application embodiment is as follows: The electric cylinder 22 is started by the external control system. The output shaft of the electric cylinder 22 retracts, driving the slide cylinder 20 to slide along the fixed cylinder 16 towards the turntable 12. During the sliding process of the slide cylinder 20, the bottom end of the connecting rod 18 moves synchronously. Since the connecting rod 18 and the connecting rod 29 are hinged to form a scissor structure, the included angle between them gradually decreases, thereby driving the arc-shaped fixed plate 17 to retract towards the axis of the fixed cylinder 16. After the winding roller 23 is sleeved on the outside of the multiple arc-shaped fixed plates 17, the output shaft of the electric cylinder 22 is extended, driving the slide cylinder 20 to slide away from the turntable 12. The included angle of the scissor structure increases, and the arc-shaped fixed plate 17 opens away from the axis of the fixed cylinder 16 until the outer wall of the arc-shaped fixed plate 17 is tightly attached to the inner wall of the winding roller 23, thus completing the fixing of the winding roller 23.

[0033] The low-smoke halogen-free irradiated wire and cable are passed sequentially through the groove of the cable guide wheel 4, around the groove of the tension wheel 10, and finally fixed at the starting end of the take-up roller 23. Under the pulling action of the cable, the tension wheel 10 is subjected to a downward force, which drives the slider 6 to slide along the slide bar 7. The spring 8 undergoes elastic deformation accordingly. The position of the tension wheel 10 is automatically adjusted by the elastic force of the spring 8, thereby realizing the real-time adjustment of the cable tension.

[0034] The servo motor 14 is started to drive the main gear 15 to rotate. The main gear 15 drives the meshing secondary gear 13 to rotate, which in turn drives the turntable 12 and the take-up roller 23 to rotate synchronously to perform the cable winding operation. During this process, the hollow shaft of the turntable 12 rotates synchronously with the turntable 12, while the connecting cable of the electric cylinder 22 is kept stably connected to the external power supply through the electric slip ring. The electric cylinder 22 is in standby state to maintain the arc-shaped fixing plate 17 to fix the take-up roller 23. At the same time, the wire drives the wire guide wheel 4 to rotate on the reciprocating screw 3 through friction. At this time, the reciprocating screw 3 drives the wire guide wheel 4 to reciprocate. The wire guide wheel 4 drives the cable to move synchronously, so that the cable is evenly distributed along the axial direction of the take-up roller 23 to achieve neat winding.

[0035] After winding is completed, turn off the power source of servo motor 14 and reciprocating screw 3, cut the cable and fix the end, start electric cylinder 22, control slide 20 to retract, drive arc-shaped fixing plate 17 to retract, release the fixation of winding roller 23, and then remove the winding roller 23 with the wound cable.
