The invention relates to a plastic shuttle core and a sewing machine spindle kit. The plastic shuttle core comprises a winding shaft and a flange which is separately arranged at both ends of the winding shaft and extending outward in its radial direction; the winding shaft and the two said flange are made of an engineering plastic and formed one in one, the winding shaft and the flange are along the axis direction. The cross section is I-type. The plastic shuttle core is made of engineering plastics. On the basis of maintaining the relative hardness, the metal shuttle core, such as iron and aluminum, has a lighter weight, better braking effect and more stable track. Compared to the traditional metal shuttle core, the hardness of the plastic spindle is moderate, and the broken needle probability can be effectively reduced. On the other hand, the friction between the plastic shuttle core and the shuttle shell is small, which can effectively solve the large friction between the metal shuttle shell and the metal shuttle core, and cause the serious wear and tear of the parts. And when the shuttle core is very small in the bottom line, it can still maintain the stable tension output.

一种塑料梭芯及缝纫机梭芯套件
本专利技术涉及缝纫零配件领域,尤其是涉及一种塑料梭芯及缝纫机梭芯套。
技术介绍
缝纫机梭芯是缝纫机内部必不可少的关键零件,随着工厂和客户对缝制产品质量要求的进一步提高,稳定的张力输出成为工厂的迫切需求。目前现有的梭芯产品材质为铁或铝,重量相对较重,当梭芯内线量较少时,由于惯性而发生空转的时间变长,会严重影响刹车质量进而影响缝制品的线迹。从而导致缝制产品达不到理想的缝制效果。且铁和铝的硬度更高,与机针接触时更容易发生断裂。并且现有技术中梭壳和梭芯同为金属,因相同材质的材料摩擦系数更大,所以更容易磨损。
技术实现思路
鉴于上述问题,本专利技术提供一种塑料梭芯及缝纫机梭芯套件,该塑料梭芯由工程塑料制成,在保持了相对的硬度的基础上,相比铁制和铝制等金属梭芯,重量较轻,具备更好的刹车效果和更加稳定的线迹;相比于传统金属制梭芯,硬度适中,可以有效降低断针概率。第一方面,本专利技术实施例提供一种塑料梭芯,包括:绕线轴和分别设置在所述绕线轴两端且沿其径向向外延伸的凸缘;所述绕线轴和两个所述凸缘均为工程塑料制成且一体成型,所述绕线轴和所述凸缘沿其轴线方向的 ...
