DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A wire cutting machine unwinding device comprises a processing table 1 and an unwinding shaft 3, wherein a first motor 2 is fixedly arranged at the upper end of the processing table 1, and the unwinding shaft 3 is fixed at the output end of the first motor 2, a cavity 4 is arranged in the middle part of the processing table 1, a second motor 5 is fixedly arranged below the cavity 4, a screw 6 is arranged at the output end of the second motor 5, a bottom plate 8 is arranged above the cavity 4, a bottom block 7 is fixedly arranged at the lower end of the bottom plate 8, the bottom block 7 is penetrated by the screw 6, and the screw 6 is threadedly connected to the bottom block 7, guide rods 9 penetrating the bottom plate 8 are fixedly arranged on both sides of the cavity 4, a first frame 10 is fixedly arranged at the upper end of the bottom plate 8, two guide wheels 11 are symmetrically arranged on the first frame 10, and a first annular groove 12 is arranged on the circumference of the guide wheel 11, and the first The motor 2 can rotate the unwinding shaft 3 and unwind the wire wound on the unwinding shaft 3. At this time, the wire is located between the two guide wheels 11 and passes through the first annular groove 12. When the cutting wire on the processing table 1 is loose, the second motor 5 is started. At this time, the screw 6 will rotate. Through the action of the threaded structure, the bottom block 7 can drive the bottom plate 8 and the first frame 10 to rise. In this process, the guide rod 9 is provided to provide a guiding effect for the bottom plate 8, so that the first frame 10 can be more stable when rising. Since the bottom plate 8 can drive the guide wheel 11 to rise, the cutting wire on the processing table 1 can become taut. When the cutting wire on the processing table 1 becomes too taut, the first frame 10 can drive the guide wheel 11 to slowly reset it, so that the cutting wire is not easy to break, thereby ensuring the cutting efficiency of the object.

[0024] The wire lacks a guiding structure on the processing table 1, which will affect the stability of the wire when it is unwound. Two second frames 13 are symmetrically arranged on the upper end of the processing table 1 and the first frame 10. The second frames 13 are fixed to the upper end of the processing table 1. Two positioning wheels 14 are symmetrically arranged on the second frames 13. The circumferential sides of the positioning wheels 14 are provided with second annular grooves. Through the second frames 13 and the positioning wheels 14, a guiding structure can be provided for the wire on the processing table 1, which can improve the stability of the wire when it is unwound.

[0025] In this structure, the second frame 13 is fixed to the upper end of the processing table 1 by screws, and the bottom block 7 is fixed to the lower end of the bottom plate 8 by screws. The screw fixing method can facilitate the assembly of the second frame 13 and the first frame 10.

[0026] When the unwinding shaft 3 is finished unwinding, it is necessary to replace the unwinding shaft 3. A positioning plate is provided at the output end of the first motor 2. The positioning plate is located at one end of the unwinding shaft 3. A slot is provided at one end of the unwinding shaft 3. A blocking block 17 inserted into the slot is provided on the positioning plate. A plurality of positioning rings 16 are symmetrically provided at one end of the unwinding shaft 3. A plurality of elastic ropes 15 are symmetrically provided on the positioning plate. A hook that cooperates with the positioning ring 16 is provided on the elastic rope 15. The elastic rope 15 is pulled so that the elastic rope 15 continues to be stretched to disengage the hook from the positioning ring 16. Then a pulling force is provided to the unwinding shaft 3 so that the blocking block 17 can be pulled out from the slot. This makes it very convenient to replace the unwinding shaft 3. After the unwinding shaft 3 is installed, the elastic rope 15 can provide a pulling force to the positioning ring 16, so that the unwinding shaft 3 can be installed more firmly on the positioning plate.

[0027] Furthermore, the card block 17 and the card slot may both be rectangular structures.

[0028] Furthermore, the first motor 2 and the second motor 5 may both be servo motors.
