Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of multi-core wire production, and particularly relates to a continuous processing device for multi-core wire production. BACKGROUND

[0002] Multi-core wire is a wire composed of multiple independent core wires, which is usually composed of multiple insulated conductor cores, each core has its own insulation layer, and the outside may have a common sheath or shielding layer. Compared with single-core wire, multi-core wire is more flexible and easier to bend and lay, and is suitable for occasions that need to be frequently moved or bent. In addition, multi-core wire has strong anti-breaking ability, uniform current distribution, and is not easy to break due to repeated bending. It can also better cope with high-frequency current and reduce the influence of skin effect.

[0003] Multi-core wire is composed of multiple core wires by twisting. Chinese patent No. CN 210702253 U discloses a metal wire twisting device, which comprises a power transmission mechanism, a wire twisting mechanism, a winding mechanism and a take-up mechanism. The power transmission mechanism is in transmission connection with the wire twisting mechanism, and the power transmission mechanism is in transmission connection with the winding mechanism through a stepless speed changer. The take-up mechanism is arranged beside the winding mechanism. The wire twisting mechanism comprises a turntable, which is uniformly provided with a wire reel. A workbench is arranged in front of the turntable, and the workbench is provided with a wire combining seat. A guide pipe is arranged outside the wire combining seat, and a first driving motor and a second driving motor are arranged side by side in the wire combining seat. The first driving motor and the second driving motor are respectively connected with a first wire combining wheel and a second wire combining wheel. An electric telescopic rod is arranged on the top of the wire combining seat, and the output end of the electric telescopic rod penetrates through the inside of the wire combining seat and is connected with a first wire cutting blade. A second wire cutting blade is oppositely arranged below the first wire cutting blade. The workbench is provided with a wire breaking alarm.

[0004] The aforementioned metal wire twisting device uses a servo motor to drive a turntable to rotate, which in turn drives multiple wire feeding frames to rotate. Each wire feeding frame has a single core wire wound on it. During the rotation of the multiple wire feeding frames, the core wires are unwound, causing them to twist together to form a multi-core wire. However, after the individual core wires are twisted together to form a multi-core wire, the surface of the multi-core wire cannot be directly exposed to the outside environment. Otherwise, external interference factors will negatively affect the multi-core wire, seriously impacting its normal use. Therefore, it is necessary to ensure that the surface of the multi-core wire is not directly exposed to the outside environment. The surface of the core wire is covered with an outer sheath or shielding layer to protect the multi-core wire. The aforementioned metal wire twisting device twists multiple single core wires into a multi-core wire and then directly uses a winding mechanism to wind the multi-core wire without covering the surface of the multi-core wire with an outer sheath. This leaves the multi-core wire directly exposed to the environment, increasing the possibility of damage to the multi-core wire. In addition, without outer sheath protection, the multi-core wire will experience compressive force after being wound, causing deformation of the inner multi-core wire or scratches on the surface, reducing the quality of the multi-core wire. Summary of the Invention

[0021] Beneficial effects:

[0022] A. In this invention, firstly, the motor, in conjunction with the reducer, drives gear four to rotate. Gear four then drives the outer driving gear to rotate via a chain. The outer driving gear synchronously drives the inner driving gear to rotate, and the inner driving gear drives the inner driven gear meshing with it to rotate. During the rotation of the inner driving gear and the inner driven gear, they synchronously drive two actuating discs to rotate. When the two actuating discs rotate, they drive the rotational unwinding mechanism located in their slots to move. The rotational unwinding mechanism moves along the trajectory of the groove. The two actuating discs rotate in opposite directions, so during the rotation of the two actuating discs, they alternately drive the three rotational unwinding mechanisms to move, thus achieving a cyclical arc motion of the three rotational unwinding mechanisms in conjunction with the grooves. Single-core wire is wound on the rotational unwinding wheels of the three rotational unwinding mechanisms. As the unwinding wheel moves, it unwinds the single-core wire, causing the three single-core wires to twist together under the action of the circular motion of the rotating unwinding wheel, forming a multi-core wire. The upright plate body supports the rotating unwinding wheel, and the connecting piece is located in the groove of the upright plate body, which allows the rotating unwinding wheel to move regularly, ensuring that the three single-core wires can be twisted together and ensuring the quality of the multi-core wire. When the rotating unwinding wheel unwinds the single-core wire, the single-core wire will move along the guide groove in the guide piece. The guide groove can increase the tension of the single-core wire, keeping the single-core wire in a taut state at all times, preventing large gaps from appearing when the three single-core wires are twisted. At the same time, the guide groove can also limit the movement distance of the single-core wire, preventing the three single-core wires from being misaligned before twisting, ensuring that the twisting work can be carried out normally.

[0023] B. In this invention, the inner driven gear rotates while simultaneously driving the outer driven gear to rotate. The outer driven gear, in turn, drives the gear one it meshes with to rotate. Gear one, through connecting shaft one, drives bevel gear one to rotate, and bevel gear one synchronously drives the rotation of the remaining meshing bevel gear two. The L-shaped frame supports connecting shaft one, thus ensuring the stability of gear one and bevel gear one, ensuring that gear one is always meshed with the outer driven gear and bevel gear one is always meshed with bevel gear two. The triangular seat combined with the inclined frame increases the load-bearing capacity of the L-shaped frame, thereby increasing its stability. Before stranding the single-core wire, the unwinding wheel is placed on multiple auxiliary wheels, allowing the guard plates at both ends of the unwinding wheel to fit against the multiple auxiliary wheels. The auxiliary wheel supports the unwinding wheel, and its annular groove restricts the movement of the unwinding wheel guard plate, thus keeping the unwinding wheel stable and preventing it from falling off. After the unwinding wheel is in place, the cylinder drives the slide block to move along the slide rail via the upright frame until the unwinding wheel moves to the stopper at the end of the drive shaft, and the stopper is inserted into the through hole in the middle of the unwinding wheel. The second bevel gear rotates synchronously, driving the drive shaft to rotate, which in turn drives the unwinding wheel to rotate via the stopper. The unwinding wheel is wrapped with a covering film, and it unwinds the covering film during rotation. Multiple auxiliary wheels also assist the rotation of the unwinding wheel, reducing the power required for rotation and preventing the stopper from slipping and spinning freely.

[0024] C. In this invention, the gathering groove of the gathering tray is funnel-shaped, with a larger opening at the end near the rotating unwinding wheel and a smaller opening at the end away from the rotating unwinding wheel. This allows the three single-core wires to approach each other at the gathering groove of the gathering tray and twist together under the drive of the rotating unwinding wheel, ultimately forming a multi-core wire. The cover film unwound by the unwinding wheel moves along the top of the guide wheel one into the arc-shaped groove and moves along the trajectory of the arc-shaped groove. The guide wheel one can increase the tension of the cover film, ensuring that the cover film will not stack or bend. Multiple pressure rollers can press down the cover film, preventing the pressure rollers from moving out of the arc-shaped groove during the movement, ensuring that the cover film always moves along the trajectory of the arc-shaped groove.

[0025] D. In this invention, the external driven gear drives gear two to rotate during rotation, gear two synchronously drives gear three, which meshes with it, to rotate, and gear three drives connecting shaft two to rotate; pulley one, which is fixedly connected to connecting shaft two, adjusts the unwinding assembly to rotate as a whole via the belt; the multi-core wire moves to the connecting plate via the take-up plate, and moves between the two wrapping and unwinding devices through the through-slot and the through-hole in the middle of the turntable; while the multi-core wire is moving, the cover film moves to the connecting plate and moves along guide wheel two into the through-slot, the end of the through-slot near the take-up plate is arc-shaped, and the cover film enters the through-slot and can move along the inner wall of the through-slot to gradually approach the multi-core wire. The groove is circular, and the covering film deforms under the pressure of the groove as it approaches the multi-core wire, thus wrapping the multi-core wire. The multi-core wire wrapped with the covering film moves between two wrapping and unwinding devices. One of the wrapping and unwinding devices has an outer sheath wrapped around it. As the wrapping and unwinding device rotates, it unwinds the outer sheath, allowing it to wrap evenly around the outer surface of the covering film, thus completely wrapping the multi-core wire. During the unwinding process, the outer sheath first passes the actuating rod and then wraps around the outer surface of the covering film. The actuating rod increases the tension of the outer sheath, preventing it from bending and ensuring that the outer sheath can wrap the covering film smoothly. Attached Figure Description

[0061] The middle of the connecting shaft 412 is rotatably connected to the top of the L-shaped frame 415, and the end of the L-shaped frame 415 away from the connecting shaft 412 is fixedly connected to the top of the placement platform 40; an inclined frame 416 is provided on the inner side of the L-shaped frame 415, and both ends of the inclined frame 416 are fixedly connected to the L-shaped frame 415; a triangular seat 417 is provided on the side of the L-shaped frame 415 away from the inclined frame 416, and the two sides of the triangular seat 417 are fixedly connected to the placement platform 40 and the L-shaped frame 415 respectively.

[0062] By adopting the above technical solution, the inner driven gear 151 rotates while driving the outer driven gear 152 to rotate. The outer driven gear 152, in turn, drives the gear 411 meshing with it to rotate. The gear 411, in turn, drives the bevel gear 413 to rotate via the connecting shaft 412. The bevel gear 413 synchronously drives the rotation of the other meshing bevel gear 414. The L-shaped frame 415 supports the connecting shaft 412, thereby ensuring the stability of the gear 411 and bevel gear 413, ensuring that the gear 411 always meshes with the outer driven gear 152 and the bevel gear 413 always meshes with the bevel gear 414. The triangular seat 417, in conjunction with the inclined frame 416, increases the load-bearing capacity of the L-shaped frame 415, thus increasing its stability. Before stranding the single-core wire, the unwinding wheel 47 is placed on multiple auxiliary wheels 49, allowing the guard plates at both ends of the unwinding wheel 47 to... The unwinding wheel 47 is attached to multiple auxiliary wheels 49, which support the unwinding wheel 47. The annular grooves of the auxiliary wheels 49 restrict the movement of the unwinding wheel 47 guard plate, thus keeping the unwinding wheel 47 stable and preventing it from falling off the auxiliary wheels 49. After the unwinding wheel 47 is placed, the cylinder 44 drives the slide block 45 to move along the slide rail 48 through the upright 46 until the unwinding wheel 47 moves to the stopper at the end of the drive shaft 42, and the stopper is inserted into the through hole in the middle of the unwinding wheel 47. The bevel gear 414 drives the drive shaft 42 to rotate synchronously during rotation. The drive shaft 42 then drives the unwinding wheel 47 to rotate through the stopper. The unwinding wheel 47 is wrapped with a covering film, and it can unwind the covering film during rotation. The multiple auxiliary wheels 49 also assist the rotation of the unwinding wheel 47, reducing the power required for the rotation of the unwinding wheel 47, thus preventing the stopper from slipping and spinning freely.

[0063] Please see Figure 10 , Figures 19-23 In this embodiment, the wrapping mechanism 3 includes a second gear 31, which meshes with an external driven gear 152 and a third gear 32 on both sides. The middle of the third gear 32 is fixedly connected to the end of a connecting shaft 34. A pulley 35 is fixedly connected to the end of the connecting shaft 34 away from the third gear 32. An unwinding assembly 37 is provided above the pulley 35, and the pulley 35 is connected to the unwinding assembly 37 via a belt 36. The end of the connecting shaft 34 near the third gear 32 is rotatably connected to a bearing seat 33.

[0064] The unwinding assembly 37 includes a connecting plate 371, one side of which is fixedly connected to the end of the frame 21 near the take-up plate 25; the connecting plate 371 has a through groove 377 inside, which communicates with the take-up groove and the arc-shaped groove 26 of the take-up plate 25; the end of the connecting plate 371 away from the frame 21 is rotatably connected to a turntable 374, the turntable 374 has a through hole in the middle, and the through hole communicates with the through groove 377; the side of the turntable 374 near the connecting plate 371 A second pulley 373 is fixedly connected to the outer side, and the second pulley 373 is connected to the first pulley 35 via a belt 36. Two wrapping and unwinding devices 375 are symmetrically fixedly connected to the side of the turntable 374 away from the second pulley 373. A lever 376 is provided between the two wrapping and unwinding devices 375, and one end of the lever 376 is fixedly connected to the turntable 374. A second guide wheel 372 is provided on the top of the connecting plate 371, and the position of the second guide wheel 372 corresponds to that of the arc groove 26.

[0065] By adopting the above technical solution, the external driven gear 152 drives the second gear 31 to rotate during rotation, and the second gear 31 synchronously drives the third gear 32 meshing with it to rotate, which in turn drives the second connecting shaft 34 to rotate; the pulley 35 fixedly connected to the second connecting shaft 34 adjusts the unwinding assembly 37 to rotate as a whole through the belt 36; the multi-core wire moves to the connecting plate 371 through the take-up plate 25, and moves between the two wrapping and unwinding devices 375 through the through hole between the through groove 377 and the turntable 374; while the multi-core wire is moving, the cover film moves to the connecting plate 371, and moves along the guide wheel 372 into the through groove 377. The end of the through groove 377 near the take-up plate 25 is arc-shaped. The cover film enters the through groove 377 and can move along the through... The inner wall of the groove 377 moves closer to the multi-core wire, and the groove 377 is circular. As the covering film approaches the multi-core wire, it deforms under the pressure of the groove 377, wrapping the multi-core wire. The multi-core wire wrapped with the covering film moves between the two wrapping and unwinding devices 375. One of the wrapping and unwinding devices 375 has an outer skin wrapped around it. While rotating, the wrapping and unwinding device 375 unwinds the outer skin, allowing it to be evenly wrapped around the outer surface of the covering film, thus completely wrapping the multi-core wire. During the unwinding process, the outer skin first passes the actuating rod 376 and then wraps around the outer surface of the covering film. The actuating rod 376 can increase the tension of the outer skin and prevent the actuating rod 376 from bending, ensuring that the outer skin can be smoothly wrapped around the covering film.

[0066] Please see Figure 8 , Figures 14-17In this embodiment, the frame assembly 2 includes a frame 21, the two ends of which are fixedly connected to the bottom middle and top middle of the upright plate body 111, respectively; the upper top of the frame 21 is provided with an arc-shaped groove 26, which extends to the middle of the end of the frame 21 away from the upright plate body 111; a pressure roller mechanism 22 is fixedly connected to the upper layer of the frame 21; multiple support seats 23 are fixedly connected to both sides of the lower layer of the frame 21, and the bottom of the multiple support seats 23 is fixedly connected to the top of the base plate 5; the middle of the inner side of the end of the frame 21 away from the upright plate body 111 is fixedly connected to... There is a gathering plate 25, and a gathering groove is provided in the middle of the gathering plate 25, which is connected to the arc groove 26; the pressure roller mechanism 22 includes a side frame 221, the two sides of which are fixedly connected to the upper two sides of the frame 21 respectively, and multiple pressure rollers 222 are rotatably connected to the top of the frame 21, all of which are located above the arc groove 26; a bearing seat 24 is fixedly connected to the lower end of the frame 21 near the gathering plate 25, and the bearing seat 24 is rotatably connected to the end of the connecting shaft 34 away from the bearing seat 33;

[0067] By adopting the above technical solution, the take-up groove of the take-up reel 25 is funnel-shaped, with a large opening at the end near the rotating unwinding wheel 131 and a small opening at the end away from the rotating unwinding wheel 131. This allows the three single-core wires to approach each other at the take-up groove of the take-up reel 25 and twist together under the drive of the rotating unwinding wheel 131, ultimately forming a multi-core wire. The cover film unwound by the unwinding wheel 47 moves along the top of the guide wheel 12 into the arc-shaped groove 26 and moves along the trajectory of the arc-shaped groove 26. The guide wheel 12 can increase the tension of the cover film, ensuring that the cover film will not stack or bend. The multiple pressure rollers 222 can press down the cover film, preventing the pressure rollers 222 from moving out of the arc-shaped groove 26 during the movement, ensuring that the cover film always moves along the trajectory of the arc-shaped groove 26.
