[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that for the sake of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0036] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device can also be positioned in other different ways, and corresponding interpretations can be made for the spatial relative descriptions used herein.

[0037] As Figure 1 and Figure 2 shown, the stranding machine according to an embodiment of the present invention includes:

[0038] A wire coiling device 1 for coiling metal wires and outputting at least two strands of metal wires;

[0039] A first guiding device 2 including at least two guiding holes 21 arranged at intervals, and at least two strands of metal wires respectively pass through the at least two guiding holes 21; and

[0040] A stranding part that gathers the ends of at least two strands of metal wires and is rotatably arranged to strand at least two strands of metal wires into a strand.

[0041] The stranding part of the stranding machine according to an embodiment of the present invention gathers the ends of at least two strands of metal wires and rotates to strand at least two strands of metals, thereby realizing automatic stranding of metal wires. Compared with manual stranding in the prior art, the work efficiency is improved. Moreover, a first guiding device 2 is arranged between the wire coiling device 1 and the stranding part to prevent the metal wires from being wound around each other before stranding, resulting in an increased workload.

[0042] As Figure 1 shown, the wire coiling device 1 of this embodiment includes a wire coiling cylinder 11 and a plurality of partition plates 12 arranged at intervals on the wire coiling cylinder 11. A wire coiling area is formed between adjacent partition plates 12, and at least two strands of metal wires are respectively output from different wire coiling areas. This arrangement can further prevent the metal wires from being wound around each other.

[0043] In order to strand metal wires of different thicknesses, the apertures of a part of the at least two guiding holes 21 in this embodiment are different from the apertures of another part of the guiding holes 21. Specifically, in this embodiment, as Figure 1As shown, two sets of guiding holes are provided on the first guiding device 2 of this embodiment. The aperture of the first set of guiding holes is smaller, and the aperture of the second set of guiding holes is larger. Therefore, the corresponding guiding holes can be selected according to actual requirements.

[0044] As Figure 1 shown, the stranding machine of this embodiment further includes a second guiding device 3 provided between the first guiding device 2 and the stranding part. Specifically, the second guiding device 3 is of a columnar structure, and a groove recessed radially inward is provided on the circumferential side surface of the columnar structure, and the metal wire passes through the groove.

[0045] The two side walls of the groove in this embodiment are inclined surfaces and the two side walls intersect. That is to say, the bottom of the groove in this embodiment is an edge. Such a setting can better guide the metal wire.

[0046] In this embodiment, the stranding machine further includes a wire take-up reel 5 rotatably provided. The wire take-up reel 5 receives the stranded metal wire output by the stranding part and winds the stranded metal wire around the circumferential end surface of the wire take-up reel 5.

[0047] The stranding machine of this embodiment further includes a frame 6 rotatably provided and at least two rollers spaced apart within the frame 6. The at least two rollers include a first roller 4 and a second roller 7. The frame 6 is rotatably provided to drive the first roller 4 to rotate, and the first roller 4 is used to wind the ends of at least two metal wires to form a stranding part. The stranded metal wire extends to the wire take-up reel 5 through the second roller 7. The settings of the first roller 4 and the second roller 7 provide a fixed path for the take-up of the stranded metal wire, and the setting of the rollers reduces the resistance suffered by the stranded metal wire during the take-up process and prevents the metal wire from being worn.

[0048] As Figure 2 shown, the stranding machine of this embodiment includes a plurality of second rollers 7.

[0049] The frame 6 of this embodiment is of a square structure. The first roller 4 is provided in the middle of the first side of the square structure, and a plurality of second rollers 7 are distributed on the second side adjacent to the first side of the square structure. In embodiments not shown in other drawings, the frame 6 may also be of other shapes, such as circular, etc.

[0050] In this embodiment, as Figure 1 shown, the wire take-up reel 5 and the frame 6 rotate differentially along the same axis. The differential rotation between the wire take-up reel 5 and the frame 6 enables the take-up of the stranded metal wire after a certain length of metal wire is stranded.

[0051] Specifically, as Figure 2As shown, the wire twisting machine of this embodiment further includes a rotating drum 9. The frame 6 is fixedly connected to the rotating drum 9 and rotates under the drive of the rotating drum 9. A rotating shaft drivingly connected to the wire winding disc 5 is sleeved inside the rotating drum 9, and this rotating shaft rotates at a differential speed with the rotating drum 9. Specifically, as Figure 2 shown, the rotating drum 11 rotates under the drive of a belt drive device 10 (the belt is not shown in the figure). Of course, in other embodiments, the rotating drum 11 can also rotate under the drive of an electrode or the like.

[0052] The wire twisting machine of this embodiment is a manufacturing device for gold products.

[0053] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements on some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
