Abstract
Description
Technical Field
[0001] This utility model belongs to the field of textile technology, specifically relating to a thread feeding and cutting mechanism. Background Technology
[0002] In garment factories or embroidery factories, mechanical equipment is now used for embroidery. The embroidery equipment has a thread feeding structure. However, the current structure is not practical because the thread will fall off after the thread cutting mechanism cuts the thread during processing. When it is needed again, the thread must be threaded through the thread cutting structure. This makes thread cutting cumbersome and results in low practicality or low work efficiency. Utility Model Content
[0003] Purpose of utility model
[0004] To address the aforementioned technical problems, this utility model provides a wire feeding and cutting mechanism to solve the technical problems mentioned in the background art.

[0007] Preferably, the wire fixing structure includes a lifting ring, the lifting ring having a mating hole inside, a sliding shaft being slidably connected inside the mating hole, and a return spring being provided between the sliding shaft and the lifting ring.
[0008] Preferably, a guide ring is provided at the other end of the sliding shaft, and a fitting ring is provided at the bottom of the guide ring. A groove is provided on the inner side of the fitting ring and the guide ring.
[0009] Preferably, the number of the bonding rings is set to multiple, and the multiple bonding rings are arranged in a ring array inside the lifting ring. The bonding rings are slidably connected to the wire feeding groove, and the guide ring is slidably connected to the auxiliary groove.
[0010] Beneficial effects
[0011] Compared with the prior art, the technical solution provided by this utility model has the following advantages: By setting two sets of wire fixing structures, when it is necessary to cut the wire passing through the wire feeding housing, the two wire fixing structures move into the wire feeding housing, thereby clamping and cutting the wire and preventing the cut wire from detaching from the wire feeding housing. At the same time, the wire cutting structure rotates left and right to cut the fixed wire. In addition, according to the position of the wire fixing structure, wires of different sizes can be clamped. There is no need to go through the cumbersome process of wire cutting mechanism when cutting the wire again. It is more practical and improves the overall work efficiency. Attached Figure Description

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] Referring now to the accompanying drawings, the various figures are intended only to illustrate certain exemplary embodiments and are not intended to limit the scope of the invention. In the various figures, the same reference numerals denote the same or corresponding parts. The dimensions and scales in the various figures are also for illustrative purposes only and should not be construed as limiting the scope of the invention; these dimensions may be enlarged relative to actual products.
[0022] Reference Figure 1-4 The diagram illustrates a wire feeding and cutting mechanism, comprising a wire feeding housing 1, a wire feeding groove 2 inside the wire feeding housing 1, auxiliary grooves 3 at the top and bottom of the wire feeding housing 1, double-headed electric telescopic rods 4 on both sides of the wire feeding housing 1, wire fixing structures 5 at both ends of the two double-headed electric telescopic rods 4, support frames 6 on both sides of the bottom outer wall of the wire feeding housing 1, a guide groove 7 at one end of the support frame 6, and a wire cutting structure 8 slidably connected between the two guide grooves 7.
[0023] Furthermore, in the above technical solution, the wire fixing structure 5 includes a lifting ring 501, with a mating hole 502 inside the lifting ring 501. A sliding shaft 503 is slidably connected inside the mating hole 502. A return spring 504 is provided between the sliding shaft 503 and the lifting ring 501. A guide ring 506 is provided at the other end of the sliding shaft 503. A fitting ring 505 is provided at the bottom of the guide ring 506. A slot 507 is provided on the inner side of the fitting ring 505 and the guide ring 506. The number of fitting rings 505 is set to multiple, and the multiple fitting rings 505 are arranged in a ring array inside the lifting ring 501. The guide ring 506 is slidably connected to the feed groove 2 and the auxiliary groove 3. The thread is passed through the feed groove 2 and then the thread is woven normally. When it is necessary to cut the thread, the double-headed electric telescopic rod 4 is activated. The double-headed electric telescopic rod 4 drives the lifting ring 501 to move towards the feed housing 1. The guide ring 506 slides inward along the inner wall of the auxiliary groove 3. Then the guide ring 506 drives the sliding shaft 503 to slide on the inner wall of the mating hole 502 and squeeze the return spring 504. Then multiple fitting rings 505 enter the interior of the feed groove 2, so that the slot 507 fits against the outer wall of the thread to clamp the thread and prevent the thread from leaving the feed groove 2 after cutting.
[0024] Furthermore, in the above technical solution, the wire-cutting structure 8 includes a rotating frame 801, which is rotatably connected to the support frame 6. Two rotating frames 801 are provided, and a connecting shaft 803 is provided between the two rotating frames 801. A wire-cutting blade 802 is provided on the outer wall of the connecting shaft 803. The connecting shaft 803 is slidably connected to the guide groove 7. The wire-cutting blade 802 is located directly below the wire-feeding housing 1. After the wire is fixed, the motor is started, and the motor drives the rotating frame 801 to rotate. The rotating frame 801 drives the wire-cutting blade 802 to rotate, and the wire-cutting blade 802 contacts the wire to cut it. Simultaneously, the connecting shaft 803 slides on the inner wall of the guide groove 7 to maintain the stability of the wire-cutting blade 802 during movement.
[0025] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
