Description

Technical Field

[0001] The invention relates to the technical field of cable processing equipment, in particular to a wire bundle unwinding rack for cable production. Background Art

[0002] During the production process, cables need to be processed by a wire bundling machine. Tightly and evenly twist single or multiple thin wires (such as copper wires and aluminum wires) together to form a wire bundle with the required specifications and structure. The wire bundling machine generally includes a pay-off frame, a twisting cage and a winding mechanism. The pay-off frame is equipped with multiple coils, which are responsible for conveying wires to the twisting cage. The twisting cage is often a rotating frame structure with multiple guide wheels or guide grooves inside to guide and position each single wire so that it can be arranged and twisted according to the predetermined twisting pitch and direction. The winding mechanism is responsible for winding the twisted cables.

[0003] Most of the unwinding stands in the prior art have a simple structure. They are supporting structures fixed on the side of the wire bundling machine. They are positioned by passing the coils or cable drums of the cables through vertically arranged poles. However, the unwinding stands with simple structures will affect the processing operations of the cables to a certain extent. Among them, after the cables on the outside of the cable drum are bundled, the operators need to remove the empty cable drums one by one for replacement; or the operators need to put the coils one by one from the top of the pole to the outside of the pole. The manual operation method greatly affects the efficiency of the cable bundling processing. In view of this, we propose a wire bundling unwinding stand for cable production.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] A wire bundle unwinding rack for cable production, as Figures 1-7 shown, includes an outer shell 1; a storage mechanism 2 is arranged at the bottom end inside the outer shell 1 for storing and placing cable reels, and when rotating, it is convenient to place multiple cable reels on the storage mechanism 2 one by one.

[0036] Specifically, the storage mechanism 2 includes a storage rack 21 which is rotatably connected to the inner side of the outer shell 1. The rotating storage rack 21 can be rotated and switched, so that after placing the cable reel, the storage rack 21 automatically rotates the subsequent idle storage space to the top, facilitating the placement operation of the subsequent cable reels. A storage rod 22 is connected to the storage rack 21. The number of storage rods 22 is an odd number. One end of the storage rod 22 is slidably connected to a counterweight rod 23, and the structure of the storage rod 22 can support the cable reel.

[0037] In addition, a support hole 25 is formed in the storage rack 21, and an adaptive plate 26 is rotatably connected in the support hole 25. The storage rod 22 is rotatably connected to the inner side of the adaptive plate 26. Bearings can be arranged on the outer side of the adaptive plate 26 to improve the rotation effect of the adaptive plate 26. At the same time, the rotating adaptive plate 26 can keep the support rod 35 and the cable reel vertical when the storage rack 21 rotates. The support rod 35 rotating in the adaptive plate 26 can rotate from the upward state at the end to the horizontal state after placing the cable reel. A limiting block is fixedly connected to the inner wall of the outer shell 1, and the structure of the limiting block can cooperate with the counterweight rod 23 and limit the counterweight rod 23 when the counterweight rod 23 tilts downward.

[0038] It should be noted that an electromagnet 27 is fixedly connected to one side of the storage rack 21, and a magnetic block 28 is fixedly connected to the counterweight rod 23. The structure of the electromagnet 27 can cooperate with the magnetic block 28 to drive the counterweight rod 23 and retract the counterweight rod 23, so as to facilitate the removal of the empty cable reel. Contact elastic pieces 29 electrically connected to the electromagnet 27 are fixedly connected to the side of the storage rack 21 and the inner side of the housing 1. The structure of the contact elastic pieces 29 can automatically control the opening and closing of the electromagnet 27, so as to realize the automatic removal operation of the empty cable reel. A return spring 24 is fixedly connected to the end of the counterweight rod 23, and the return spring 24 is fixedly connected to the storage rod 22. The return spring 24 can push the counterweight rod 23 outwards through elasticity, so that the counterweight rod 23 maintains a state of protruding outwards.

[0039] On this basis, a feeding port 11 is opened at the top end of the housing 1. The structure of the feeding port 11 can facilitate the feeding operation of the cable reel by the staff. A discharging port 12 is opened at the bottom end of the side of the housing 1. A collecting frame 13 is connected to the end of the discharging port 12. The structure of the discharging port 12 can facilitate the placement of the collecting frame 13, and at the same time, the collecting frame 13 can facilitate the collection operation of the empty cable reel. A wire laying groove 14 is opened at the bottom end inside the housing 1. The structure of the wire laying groove 14 can accommodate and guide the cable.

[0040] Embodiment 2

[0041] As Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 shown, on the basis of Embodiment 1, a guiding mechanism 3 is arranged inside the housing 1 for guiding the movement of the cable; the guiding mechanism 3 is arranged adjacent to the storage mechanism 2, and the guiding mechanism 3 can perform a guiding operation on the cable.

[0042] In this embodiment, the guiding mechanism 3 includes a guiding roller 31. The guiding roller 31 is fixedly connected inside the wire laying groove 14. The structure of the guiding roller 31 can guide the cable, so as to improve the stability of the cable during movement and avoid the abrasion of the cable caused by contact with the edge of the internal structure of the housing 1. An adjusting roller 32 is slidably connected inside the wire laying groove 14. Both ends of the adjusting roller 32 are connected with buffer springs 33. The ends of the buffer springs 33 are fixed on the housing 1. The adjusting roller 32 can move and adjust inside the wire laying groove 14, so as to adapt to different wire laying requirements.

[0043] In addition, a guiding groove 34 is formed in the inner wall of the outer shell 1. A support rod 35 is slidably connected inside the guiding groove 34. A support roller 36 is fixedly connected to the middle of the support rod 35. The structure of the guiding groove 34 can facilitate the sliding adjustment of the support rod 35, so as to perform sliding adjustment between support and guidance at different heights to meet the wire pay-off requirements at different heights. The support roller 36, the guiding roller 31 and the adjusting roller 32 are all in a spindle shape. The spindle shape can make the guiding structure match the wire structure correspondingly, so as to limit the wire during the guiding process and prevent the wire from shifting.

[0044] Embodiment 3

[0045] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 8 shown, on the basis of Embodiment 2, a wire pay-off mechanism 4 is provided for paying off the stored wire. The wire pay-off mechanism 4 is arranged on one side of the outer shell 1 away from the storage mechanism 2. The wire pay-off mechanism 4 can perform wire pay-off operation so that the wire can be aligned with the subsequent wire drawing machine.

[0046] In this embodiment, the wire pay-off mechanism 4 includes a support frame 41 which is slidably connected to the inner side of the outer shell 1. The structure of the support frame 41 can support the wire pay-off mechanism 4. The slidably connected support frame 41 can be slidably adjusted inside the outer shell 1, so as to adjust the height of the support frame 41 to meet the wire pay-off requirements at different heights. A clamping block 42 is slidably connected to the support frame 41. A clamping spring 43 is fixedly connected to the outside of the clamping block 42. A clamping roller 44 is rotatably connected to the inside of the clamping block 42. The clamping roller 44 is in a spindle shape. The clamping block 42 can perform clamping and positioning operation on the wire through the clamping roller 44 on the inside. The spindle-shaped clamping rollers 44 can be combined to form a diamond-shaped clamping structure, so as to prevent the wire from shifting during movement. The structure of the clamping spring 43 can improve the clamping effect of the clamping roller 44.

[0047] Furthermore, a positioning rod 45 is slidably connected to the support frame 41. The end of the positioning rod 45 is rotatably connected to the support rod 35. The structure of the positioning rod 45 can position the support rod 35, so that the support rod 35 and the support roller 36 are at the same height as the support frame 41. A screw rod 46 is rotatably connected inside the outer shell 1. The screw rod 46 passes through the support frame 41 and meshes with the support frame 41. By rotating the screw rod 46, the support frame 41 can be driven to move along the direction of the screw rod 46. A driving handle 47 is fixedly connected to the end of the screw rod 46. The driving handle 47 can facilitate the staff to control the screw rod 46. A guiding rod 48 is fixedly connected inside the outer shell 1. The guiding rod 48 passes through the support frame 41. The structure of the guiding rod 48 can guide the movement of the support frame 41.

[0048] When the cable wire unwinding rack of the present invention is used, the staff first places the cable reels on the storage structure one by one. In the initial state, the counterweight rod 23 moves outward under the elastic action of the return spring 24. At this time, the end of the storage rod 22 close to the counterweight rod 23 is heavier, and the counterweight rod 23 presses down one end of the storage rod 22, and the other end of the storage rod 22 is then extended from the feed port 11 and tilted. At the same time, after the counterweight rod 23 rotates downward, it is restricted by the limit block and cannot rotate. At this time, after the cable reel is placed on the storage rod 22, the weight of the cable reel presses the storage rod 22 downward, and the other end of the storage rod 22 is then lifted up and drives the counterweight rod 23 to rotate upward synchronously. After the counterweight rod 23 rotates upward, it is misaligned with the limit block, and the counterweight rod 23 loses the restriction of the limit block. Subsequently, since the number of storage rods 22 is an odd number, the center of gravity of the storage rod 22 and the cable reel is not on the same vertical line as the center of the circle of the storage rack 21, so the storage rack 21 rotates in the direction of the cable reel under the gravity of the cable reel. The subsequent vacant storage rod 22 is then rotated to the feed port 11 to facilitate the subsequent feeding operation. When performing the wire-laying operation, after the cable drum rotates to the bottom with the storage rack 21, the cable on the cable drum can be extended from the wire-laying groove 14. The staff can pull the cable through the guide roller 31, the adjustment roller 32 and the support roller 36, and then perform the wire-laying operation after the cable is clamped and positioned by the clamping block 42 and the clamping roller 44 inside the clamping block 42. The staff can drive the support frame 41 to lift and lower by rotating the screw rod 46 through the driving handle 47. After the support frame 41 is moved and adjusted, the support frame 41 drives the support rod 35 to move and adjust through the positioning rod 45, so that the support rod 35 can be moved and adjusted laterally when it is lifted and lowered with the moving frame, thereby keeping the positioning length of the cable similar during the wire-laying operation at different heights. The adjusting roller 32 structure tightens the cable under the elastic drive of the buffer spring 33, improves the positioning and guiding effect of the cable, and prevents the cable from detaching from the inner side of the adjusting roller 32 or the supporting roller 36. After completing the unwinding operation of a single cable drum, the storage rod 22 at the feed port 11 is pressed inward, the storage rack 21 rotates accordingly, and the empty cable drum rotates to the top of the collection frame 13. At this time, the contact spring 29 on the outside of the storage rack 21 contacts the contact spring 29 on the inside of the housing 1 and activates the electromagnet 27, and the counterweight rod 23 moves inward under the action of magnetism. At this time, the center of gravity of the storage rod 22 moves to one end of the storage rod 22, and the end of the storage rod 22 tilts downward. The empty cable drum slides downward along the tilted storage rod 22 and falls into the collection frame 13 for recovery.
