However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0032] Among them, the adjacent ends of the plurality of pull valve assemblies 5 are all fixed to the central axis 3 .

[0033] In this embodiment, the front plate assembly 2 includes a front panel 25 , on which a front panel thread outlet hole 21 extending from front to back is formed, and a working groove 22 for convenient replacement of the pull valve assembly 5 is formed on the top of the front panel 25 .

[0034] In this embodiment, an indicator light 24 indicating the wire output status of the front plate wire output hole 21 is installed above the front plate wire output hole 21, and a wire roller 23 is rotatably connected to the front panel 25, and the wire roller 23 is located below the front plate wire output hole 21.

[0035] The front plate assembly 2 can wrap the transmission assembly 4 , the central shaft 3 and the plurality of pull valve assemblies 5 inside, preventing external debris and impurities from entering and damaging the transmission assembly 4 , the central shaft 3 and the plurality of pull valve assemblies 5 .

[0036] In this embodiment, the transmission assembly 4 includes a main gear plate 41 and a driving motor 44. The main gear plate 41 and the pull valve assembly 5 are both equipped with teeth 42. A driving gear 43 is meshed on one side of the main gear plate 41. The output shaft of the driving motor 44 is connected to the driving gear 43 through a coupling.

[0037] The plurality of pull valve assemblies 5 are all engaged with the main gear plate 41 .

[0038] In this embodiment, the pull valve assembly 5 includes a positioning block 51, on which a plurality of first clamping blocks 54 are fixedly mounted, the positioning block 51 is engaged with the main gear disc 41 through the plurality of first clamping blocks 54, a pull valve body 52 is inserted into the positioning block 51, and a valve wire outlet hole 53 for passing an iron wire is provided on the pull valve body 52, and an insert block 55 is installed on the side of the positioning block 51 away from the teeth 42, and the insert block 55 is inserted into the center shaft 3.

[0039] In this embodiment, two second clamping blocks 56 are slidably mounted on the positioning block 51, and the back ends of the two second clamping blocks 56 are fixedly connected to support springs 57, and the ends of the two support springs 57 away from the second clamping blocks 56 are fixed to the inner wall of the positioning block 51;

[0040] The two second clamping blocks 56 are both engaged with the pull valve body 52 .

[0041] The pull valve assembly 5 adopts a modular design, which makes replacement and adjustment simple and easy. The operator can perform simple operations, such as pulling the second clamping block 56 to squeeze the support spring 57, thereby canceling the limit of the pull valve body 52 and realizing the rapid replacement of the pull valve body 52. ​​This design not only improves production efficiency, but also reduces the difficulty of operation.

[0042] In this embodiment, the central axis 3 includes a rotating rod 31, on which a plurality of electric push rods 32 are mounted, and a plurality of engaging grooves 33 are opened on the rotating rod 31, and the plurality of engaging grooves 33 are all engaged with adjacent plug blocks 55, and the plurality of rotating rods 31 all penetrate the adjacent plug blocks 55 and extend into the rotating rod 31.

[0043] The central shaft 3 can assist the main gear plate 41 in further fixing the plurality of pull valve assemblies 5 .

[0044] Furthermore, the aperture of the wire outlet hole 21 of the front plate is the largest, followed by the multiple valve wire outlet holes 53. There are four pull-valve assemblies 5, which means that there are also four valve wire outlet holes 53, but the apertures of the four valve wire outlet holes 53 are different, from small to large in sequence. However, the aperture of the largest pull-valve body 52 is still slightly smaller than the aperture of the front plate wire outlet hole 21. In this way, different valve wire outlet holes 53 can be selected according to the metal wire diameter required for the batch of wires while ensuring smooth wire output.

[0045] The use method and working principle of the device: When using the device, first assemble the central shaft 3, the transmission assembly 4 and the pull valve assembly 5, engage the first clamping block 54 on the plurality of positioning blocks 51 with the main toothed disc 41, and insert the plugging block 55 on the positioning block 51 into the corresponding clamping groove 33, then start the electric push rod 32 to penetrate the corresponding plugging block 55, and repeat this operation four times to install all four pull valve assemblies 5 on the main toothed disc 41, and the assembly is completed;

[0046] When in use, first, according to the wire diameter required for the batch of wires, the driving motor 44 is driven to drive the active gear 43 to rotate, and the combination of the main toothed disc 41 and the pull valve assembly 5 is driven to rotate through the active gear 43 and the teeth 42. According to the required diameter, the valve wire outlet hole 53 on the pull valve assembly 5 that meets the wire outlet diameter is located on the same axis as the front plate wire outlet hole 21. At this time, the metal wire is inserted from the large end of the pull valve body 52 in the wire drawing machine chassis 1 and is passed out from the wire outlet end of the valve wire outlet hole 53 of the pull valve body 52. ​​When replacement is required, the driving motor 44 is driven to rotate so that the valve wire outlet hole 53 on different pull valve assemblies 5 is located on the same axis as the front plate wire outlet hole 21. When wire is coming out from the inside of the wire drawing machine chassis 1, the indicator light 24 will light up in advance to indicate that the machine is about to come out, and the wire outlet direction of the metal wire can be adjusted by guiding the metal wire through the wire roller 23 first.

[0047] There are four pull-valve assemblies 5 in total, but pull-valve bodies 52 with different valve wire outlet holes 53 can be selected according to the wire outlet diameters of different batches. When replacing the pull-valve body 52, it is only necessary to pull the second clamping blocks 56 on both sides to squeeze the corresponding supporting springs 57, and cancel the limit of the second clamping blocks 56 on the pull-valve body 52, and then the pull-valve body 52 can be pulled out for replacement.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
