Detailed Description

Embodiments of the present invention will now be described with reference to the drawings, wherein like parts are designated by like reference numerals. The embodiments described below and the technical features of the embodiments may be combined with each other without conflict.

The design principle of the invention is that the lower end of the sinker is arranged in the needle-moving track of the sinker cam, the sinker guiding mechanism is arranged outside the sinker cam, the sinker passes through the guiding mechanism in a penetrating way, the falling object cylinder is arranged inside the sinker cam, and the bottom of the falling object cylinder is lifted and rotated back and forth through the control mechanism, so that the lifting of the sinker cam and the swinging of two salient points of the sinker cam are driven to drag the sinker to perform internal and external expansion and the thread inlet of the sinker is changed back and forth to the thread inlet position.

Fig. 1 shows a perspective view of a circular loom sinker device of the present invention. Fig. 2 shows a partial enlarged view.

Fig. 3 shows an exploded view of the upper part.

As shown in fig. 2-3, the outer side of the bell mouth 61 of the falling cylinder is wrapped with an upper sedimentation steel ring 4, and a lower sedimentation steel ring 5 is arranged below the upper sedimentation steel ring 4 at a certain distance. The upper and lower sinking steel rings 4 and 5 form a sinking triangle, and a sinking gap 51 is left between the upper and lower sinking steel rings as a needle moving track (see fig. 3). The plurality of sinkers 1 are uniformly arranged outside the funnel-shaped mouth 61 of the falling cylinder at the upper end of the falling cylinder 6, and the protrusions 111 of the sinkers 1 are positioned in the settling gap 51. When the falling cylinder 6 rotates to drive the upper and lower sedimentation steel rings 4 and 5 to rotate, the sedimentation gap 51 fluctuates in height, so that the sinker 1 in the sedimentation gap 51 is jacked up or falls down. The shape of the relief of the settling gap 51 may thus form: the opposite positions of the upper sedimentation steel ring 4 and the lower sedimentation steel ring 5 are respectively provided with sedimentation convex points 52 and sedimentation concave points 53.

The outer sides of the upper sedimentation steel ring 4 and the lower sedimentation steel ring 5 are provided with inner guide rings 3, and the outer sides of the inner guide rings 3 are provided with outer guide rings 2. The lower end of the inner guide ring 3 is extended outwardly with a rim 32 so as to be able to hold the outer guide ring 2 at the outside, and preferably, the width of the inner guide ring rim 32 is the same as the thickness of the outer guide ring 2. The inner guide ring 3 is provided with a second groove 31 corresponding to the sinker 1, and the upper edge of the outer guide ring 2 is provided with a first groove 21 corresponding to the sinker 1. Alternatively, the inner guide ring 3 and the outer guide ring 2 may be integrally formed.
