TECHNICAL FIELD
[0001] The utility model belongs to sewing machine accessory technical field, concretely relates to a sewing machine rotating shuttle shuttle holder structure. BACKGROUND
[0002] In the operation process of the lockstitch series sewing machine, the rotating shuttle runs at high speed. The existing rotating shuttle structure has a obvious problem, that is, the ring type bobbin case is sleeved at the fixed position of the shuttle holder lock door hole, which is easy to produce the condition when the rotating shuttle runs at high speed. According to the actual use, it is speculated that this condition may show that the ring type bobbin case produces displacement and other unstable phenomena, and further causes noise. The generation of noise not only will influence the working environment of the sewing machine operator, and long-term in the noise environment can cause hearing damage and other occupational health problems, but also reflects the instability of the working state of the sewing machine to a certain extent, which can affect the sewing quality and reduce the production efficiency. At present, there is a lack of effective solution to this problem in the market, and the existing technology cannot well solve the problem of noise caused by the instability of the ring type bobbin case in the shuttle holder lock door hole position.
[0003] Therefore, the utility model designs a sewing machine rotating shuttle shuttle holder structure, which can solve the problem of noise. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at providing a sewing machine rotating shuttle shuttle holder structure to solve the problem proposed in the above background technology.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a sewing machine rotating shuttle shuttle holder structure, which comprises a shuttle holder main body, a shuttle holder lock door hole is formed in the top edge of the shuttle holder main body, a pair of anti-collision inserts is inlaid in the inner side of the shuttle holder lock door hole, and the surface of the anti-collision insert is flush with the surface of the shuttle holder lock door hole and the surface of the shuttle holder main body.
[0006] Preferably, the inside of the shuttle holder main body is further provided with a ring type bobbin for storing sewing thread.
[0007] Preferably, the outer surface of the shuttle holder main body is provided with a lower limiting protrusion, and the lower limiting protrusion and the shuttle holder main body are an integral structure.
[0008] Preferably, the top edge of the shuttle holder main body is provided with an upper limiting protrusion, and the upper limiting protrusion and the shuttle holder main body are an integral structure.
[0009] Preferably, the lower limiting protrusion and the upper limiting protrusion are distributed on the shuttle holder main body in a staggered manner.
[0010] Preferably, the inner side of the shuttle holder lock door hole is provided with an embedding groove corresponding to the anti-collision insert, and the shape and size of the embedding groove are matched with the shape and size of the anti-collision insert.
[0011] Preferably, the anti-collision insert is a plastic member or a silica gel member.
[0012] Compared with the prior art, the utility model has the beneficial effects that:
[0013] Reduce noise: through the anti-collision insert of plastic or silica gel material, the noise produced by the collision and displacement between the ring type bobbin sleeve and the lock door hole of the shuttle frame is effectively reduced, a more quiet working environment is created for the sewing machine operator, and the professional health risk is reduced.
[0014] Improve sewing quality: reduce the unstable condition of the ring type bobbin sleeve, so that the rotating shuttle is more stable when running at high speed, which is beneficial to ensure the stitch uniformity and stability of the sewing machine during the sewing process, and improve the sewing quality.
[0015] Improve production efficiency: the stable rotating shuttle working state reduces the number of stop adjustment caused by noise and unstable factors, improves the actual working time of the sewing machine, and improves the production efficiency.
[0016] Simple structure, easy to implement: the utility model only inlays the anti-collision insert in the lock door hole part of the existing shuttle frame, without the need to make large-scale changes to the overall structure of the sewing machine, which is low in cost and easy to implement and promote in production.
