The adjacent contact blocks 8 not pressed keep a protruding state under the action of first reset spring 7, forming a physical isolation belt, which effectively prevents the adjacent raw material bundles from contacting and sliding, and the limiting assembly is arranged between connecting seat 2 and connecting disc 3, and the limiting assembly is used for limiting the rotation of connecting disc 3.

[0024] As shown in Figure 1 and Figure 3 , the limiting assembly includes a clamping block 9, an operating plate 10 and a second reset spring 12, the operating plate 10 is slidably connected in the connecting seat 2, and the operating plate 10 extends transversely outward, the bottom side of the connecting disc 3 is connected with several clamping blocks 9, the part of the operating plate 10 located in the connecting seat 2 is separated into several grooves 11, the clamping blocks 9 are limitedly matched with the grooves 11, the second reset spring 12 is arranged in the connecting seat 2, one end of the second reset spring 12 is connected with the connecting seat 2, and the other end is connected with the operating plate 10, when it is necessary to adjust the orientation of the rack 5, the worker presses the operating plate 10 with one hand, the operating plate 10 slides downward in the inner cavity of the connecting seat 2, driving the second reset spring 12 to compress, at this time, the grooves 11 on the operating plate 10 are disengaged from the clamping blocks 9 on the bottom of the connecting disc 3, and the circumferential limitation of the connecting disc 3 is released. The worker can push the support rod 4 with the other hand to drive the whole rack 5 to rotate, so that the target round rod is turned to the operating station.

[0025] As shown in Figure 3 , it further includes a guide ring 13, each groove 11 is provided with a guide ring 13, the upper end of the guide ring 13 is provided with an inwardly inclined slope, the guide ring 13 is slidably connected with the clamping block 9, and the slope design of the guide ring 13 ensures that the clamping block 9 can be smoothly clamped without accurate alignment during resetting.

[0026] As shown in Figure 2 , it also comprises a roller 14, and each contact block 8 is rotationally connected with a roller 14 at the top, and the rotation of the raw material bundle drives the roller 14 to rotate, converting sliding friction into rolling friction, reducing the traction resistance by more than 60%.

[0027] As shown in Figure 1 , it also comprises a limiting block 15, and each end of the circular rod of the placing rack 5 close to the support rod 4 is fixed with a limiting block 15. When the raw material bundle becomes lighter due to the extraction of the wire, the limiting block 15 can block the axial sliding of the raw material bundle, effectively preventing the wires of different raw material bundles from crossing and winding with each other.

[0028] As shown in Figure 1 , it also comprises an anti-skid sleeve 16, and the operating plate 10 is sleeved with an anti-skid sleeve 16, and the anti-skid sleeve 16 sleeved on the operating plate 10 is made of high-friction rubber material, which can not only enhance the operation feeling, but also prevent the slipping phenomenon caused by hand sweat, ensuring the stability of the pressing action.

[0029] The staff takes the raw material wire wound into a bundle from the warehouse, and selects a suitable placing position according to the hardness of the raw material wire. If the raw material wire is relatively hard, it is placed at the outer end of the circular rod of the placing rack 5, leaving a sufficient bending radius. If the raw material wire is relatively soft, it is placed close to the limiting ring 15, reducing the distance of the raw material wire suspended in the middle and reducing the situation of mutual winding of different wires. After determining the placing position, the raw material wire is placed on the placing rack 5, the raw material bundle presses the contact block 8, the contact block 8 slides downward along the placing rack 5 and the sleeve 6, compresses the first reset spring 7, and then all the contact blocks 8 in contact with the raw material bundle are pressed downward, while the contact blocks 8 not pressed by the raw material bundle limit the movement of the raw material bundle from both sides. When pulling the wire from the raw material bundle for subsequent processing, the raw material bundle rotates on the placing rack 5, and the contact blocks 8 on both sides of the raw material bundle can ensure that the raw material bundle does not move, and the rollers 14 on the contact blocks 8 can reduce the friction, and the rollers 14 rotate with the rotation of the raw material bundle.

[0030] If the whole raw material wire is used, as the raw material wire is extracted, the raw material bundle becomes lighter, and the contact block 8 may lift the raw material bundle, and the raw material bundle moves to the middle. At this time, the limiting ring 15 can block the sliding of the raw material bundle, prevent the raw material bundles from approaching each other, and reduce the situation of mutual winding of the wires. If there is remaining raw material wire, the cut wire is wound in the raw material bundle, and the remaining raw material wire is taken off from the placing rack 5. The first reset spring 7 rebounds and pushes the contact block 8 to slide upward to reset, and the remaining raw material wire is wound into a bundle by the transparent belt and placed in the warehouse.

[0031] When multiple raw material bundles are placed at the same time, the staff places them by rotating the placing rack 5, otherwise the staff needs to rotate the placing rack 5, which increases the workload. After the raw material bundles are placed in the warehouse, they need to be moved to the production site, and the entire device is moved by the moving wheels 101, at which time the rotation of the placing rack 5 needs to be limited. When the support rod 4 and the placing rack 5 need to be rotated, the operating plate 10 is pressed down, the second reset spring 12 is compressed, the recess 11 on the operating plate 10 is separated from the clamping block 9, so that the connecting disc 3 can rotate on the connecting seat 2, and the position of the placing rack 5 is adjusted. The staff can be in one position to complete the placement of the four round rods of the placing rack 5 with different raw material bundles. After the operating plate 10 is released, the second reset spring 12 rebounds and pushes the operating plate 10 to slide upwards, the clamping block 9 is smoothly inserted into the recess 11 through the inclined surface on the top of the guide ring 13, the rotation of the connecting disc 3 is limited through the cooperation of the clamping block 9 and the recess 11, and the stability of the placing rack 5 is ensured.

[0032] The anti-skid sleeve 16 can optimize the stability of the pressing operating plate 10, increase the friction, and prevent the hands and the operating plate 10 from sliding relative to each other. A sufficient number of contact blocks 8 can place raw material bundles with different hardness on one round rod of the placing rack 5, and are limited relative to each other by the contact blocks 8, which further optimizes the placement effect of the placing rack 5.

[0033] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
