[0002] At present, wire and cable production equipment is equipped with a take-up rack and a pay-off rack, which are convenient for winding wires or cables around a wire reel during the wire and cable production process. For this reason, according to the usability of wire and cable production, the equipment for paying off wires or cables from a wire reel is called a pay-off rack; the equipment for winding wires or cables around a wire reel is called a take-up rack. The pay-off rack and the take-up rack are frequently used in wire and cable production equipment and are also essential for wire and cable production equipment. The take-up rack and the pay-off rack are divided into different specifications according to the size of the wire reel used.

[0003] For the existing cable winding and unwinding equipment, the rotation drive of the wire reel generally uses a transmission mechanism to transmit the driving force to the wire reel. This structure has many connecting components, occupies a large space, and has a large transmission loss due to many transmission components. Summary of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 As shown in the figure, the present utility model is a motor-driven wire winding and unwinding mechanism, including a main body frame 1. A frame bottom plate 2 is arranged at the bottom of the main body frame 1. A slewing bearing 3 is fixedly installed at the center position of the upper end of the main body frame 1. A slewing support 4 is installed on the slewing bearing 3; A wire reel seat 5 for placing a wire reel frame is fixedly installed at the upper end of the slewing support 4. A wire reel shaft 6 is fixedly installed at the center position of the wire reel seat 5;

[0027] Specifically, the wire reel shaft 6 includes a middle shaft bracket 61 fixedly installed at the center of the wire reel seat 5, and an inserted shaft rod 62 is detachably installed on the middle shaft bracket 61. The inserted shaft rod 62 can be flexibly adjusted according to different wire reel specifications to ensure accurate limitation of the wire reel.

[0028] An adjusting mechanism 9 is fixedly installed at a position close to the edge of the main body frame 1. A traction mechanism 8 for driving the rotation of the wire reel seat 5 is installed on the adjusting mechanism 9; The traction mechanism 8 is slidably arranged on the main body frame 1.

[0029] The wire reel base 5 includes a central plate 51 fixedly installed on the slewing support 4. On both sides of the central plate 51, side support plates 53 are fixedly connected through I-shaped plates 52. The two groups of side support plates 53 and the central plate 51 form a disc support structure.

[0030] The wire reel base 5 can be flexibly adjusted according to the specifications of the wire reel for winding and unwinding. When the specifications of the wire reel for winding and unwinding are small, the wire reel can be directly supported for winding and unwinding through the central plate 51, thereby reducing the weight of the entire wire reel winding and unwinding mechanism and also synchronously reducing the energy loss required by the traction mechanism 7.

[0031] When the specifications of the wire reel are large, the corresponding side support plates 53 are installed to ensure the overall strength of the entire wire reel base 5, complete the support effect on the entire wire reel, and avoid damage caused by concentrated stress on the wire reel base 5.

[0032] An outer ring plate 54 connected to the traction mechanism 8 is sleeved on the outer peripheral wall of the disc support structure.

[0033] Specifically, the outer ring plate 54 is made of wear-resistant material, effectively reducing the wear caused when in frictional contact with the traction mechanism 8. In addition, the surface roughness of the outer ring plate 54 is relatively high, ensuring that the traction wheel 83 can stably rotate and drive the wire reel base 5.

[0034] A plurality of limiting grooves 511 are provided on the central plate 51, and a limiting mechanism 7 is installed at the limiting grooves 511.

[0035] Specifically, the traction mechanism 7 includes a limiting bottom plate 71 installed at the lower end of the central plate 51, and a limiting shaft 72 is detachably installed on the limiting bottom plate 71, and the upper end of the limiting shaft 72 extends out of the upper surface of the central plate 51.

[0036] By matching the limiting mechanism 7 with the limiting holes provided on the wire reel, the stability of the wire reel installed on the wire reel base 5 is ensured, thereby improving the stability during wire reel winding and unwinding.

[0037] The traction mechanism 8 includes a traction machine frame 81, a traction motor 82 is fixedly installed on the traction machine frame 81, and a traction wheel 83 is fixedly installed at the output end of the traction motor 82.

[0038] Furthermore, an adjusting connecting plate 84 is fixedly installed on the traction machine frame 81, and the adjusting connecting plate 84 is connected to the adjusting mechanism 9.

[0039] The traction mechanism 8 further includes a guiding sliding plate 85. The traction machine frame 81 is fixedly installed on the guiding sliding plate 85, and a limiting guide rail 10 matched with the guiding sliding plate 85 is fixedly installed on the main machine frame 1.

[0040] The traction motor 82 drives the traction wheel 83 to rotate, and then directly drives the reel seat 5 to rotate through the frictional contact between the traction wheel 83 and the outer periphery of the reel seat 5, effectively reducing the connection structure for the rotational drive of the reel seat 5. The direct connection drive has a good effect and greatly saves space.

[0041] The adjusting mechanism 9 includes an adjusting bottom plate 91, an adjusting vertical plate 92 is fixedly arranged on the adjusting bottom plate 91, an adjusting screw rod 94 is threadedly penetrated and connected on the adjusting vertical plate 92, an adjusting head 95 is fixedly connected to the end of the adjusting screw rod 94, and the adjusting head 95 is rotatably connected to the traction mechanism 8.

[0042] Two limit nuts 93 are threadedly connected to the adjusting screw rod 94, and the two limit nuts 93 are symmetrically distributed on both sides of the adjusting vertical plate 92.

[0043] Since the drive of the reel seat 5 in this solution is realized by the frictional force between the traction wheel 83 of the traction mechanism 8 and the reel seat 5, and during the frictional drive process, frictional loss will occur between the traction wheel 83 and the reel seat 5, resulting in a decrease in the frictional force and affecting the traction effect. Therefore, by setting the adjusting mechanism 9, the position of the traction mechanism 8 can be flexibly adjusted, so that the traction mechanism 8 always has a good traction effect on the reel seat 5, thereby improving the service life of the wire winding and unwinding mechanism.

[0044] The working principle of the present utility model: Place the reel that needs to wind and unwind the wire on the reel seat 5, insert the limit shaft 72 into the limit hole on the reel, and then adjust the relative position between the traction mechanism 8 and the reel seat 5 through the adjusting mechanism 9, so that the traction wheel 83 is closely attached to the outer periphery of the reel seat 5. The traction motor 82 drives the traction wheel 83 to rotate to drive the reel seat 5 and the reel to rotate, realizing the drive for winding and unwinding the wire.

[0045] A detailed description of an embodiment of the present utility model has been given above, but the content described is only a preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
