Problems solved by technology

[0004] The above-mentioned related technical solutions have the following defects: the thread-passing part of the shuttle frame is an inclined slope, and the whole is a rigid structure. It is impossible to be exactly the same, so that the rope may stagnate when passing the inclined surface of the shuttle frame, and then as the tension gradually increases, the rope will suddenly relax and quickly pass over the inclined surface, making the formed line There is a loose pick in the trace, that is, the string between two adjacent pinholes is not tightened

Embodiment Construction

[0037] The following is attached Figure 1-4 The application is described in further detail.

[0038] see figure 1 , a rotary hook, including an inner shuttle 1, an outer shuttle 2 connected to the outer peripheral side of the inner shuttle 1 through a rotating shaft coaxially rotating, and an inner shuttle pressing plate fixed to the outer end of the outer shuttle 2 by bolts.

[0039] see figure 1 and figure 2 , the inner shuttle pressure plate includes a pressure plate body 3 and a wire spring 4, the pressure plate body 3 is in the shape of an arc plate as a whole, and the inner peripheral end surface of the pressure plate body 3 is integrally formed with a wrapping 5 on the side close to the side wall, and the wrapping 5 is perpendicular to The pressure plate body 3, when the pressure plate body 3 abuts against the outer peripheral surface of the outer shuttle 2, the wrapping 5 covers the upper end of the outer shuttle 2, the outer peripheral end surface of the outer sh...

Abstract

The invention relates to an inner shuttle pressing plate and a rotating shuttle, the inner shuttle pressing plate comprises a semi-arc-shaped pressing plate body, one end of the pressing plate body is provided with an inclined protruding edge tip, one side edge of the edge tip is an inclined edge, the other side edge of the edge tip is a flat edge, the flat edge is flush with one side edge of the pressing plate body, and the pressing plate body is provided with an inclined groove. A V-shaped steel wire spring is arranged on the side, away from the pressing plate body, of the edge tip, the steel wire spring comprises a first deformation steel wire, a second deformation steel wire and a sharp corner part, the first deformation steel wire abuts against the flat edge of the edge tip, the second deformation steel wire is arranged on the inclined edge of the edge tip in a suspended mode, and the sharp corner part is connected with the first deformation steel wire. And the sharp corner part is suspended at the intersection of the flat edge and the inclined edge. The method has the advantages that the probability of loose picking is reduced, and stitches are smoother.

Description

technical field [0001] The present application relates to the technical field of textile equipment, in particular to an inner shuttle pressing plate and a rotary hook. Background technique [0002] At present, the rotary hook is widely used in various sewing equipment, and it is also a functional accessory product that the sewing equipment must have for sewing. The rotary hook of the sewing machine is used to hook the upper thread on the needle of the sewing machine to rotate, and then walk around the bottom thread in the bobbin of the inner bobbin frame of the rotary hook to form a stitch. The rotary hook is composed of an outer rack and an inner rack. The outer rack and the inner rack are matched by the guide groove in the outer rack and the guide rail on the inner rack. When working, the outer rack is on the inner rack. rotate. [0003] The working principle of the rotary hook is usually after the needle rises for a certain distance, the hook tip of the rotary hook bed ...
