Detailed Description

As shown in fig. 1 and 2, the invention discloses a yarn gripper for textile machines, comprising: the yarn feeding device comprises a base 1, a U-shaped mounting seat I2, a yarn wheel 3, a vertical plate 4, a rectangular groove 5, a guide rail 6, a sliding seat 7, a cylinder 8, a U-shaped mounting seat II 9, a sliding rod 10, a limiting block 11, a spring 12, a rotating shaft 13 and a clamping wheel 14, wherein the left side of the upper end face of the base 1 is fixedly connected with the U-shaped mounting seat I2, the opening of the U-shaped mounting seat I2 is upward, a yarn wheel 3 is rotatably mounted in the opening of the U-shaped mounting seat I2 through a short shaft, an annular groove 31 is formed in the outer arc surface of the yarn wheel 3, the vertical plate 4 is vertically and fixedly connected to the inner side of the base 1, the vertical plate 4 is arranged behind the yarn wheel 3, the rectangular groove 5 is formed in the upper side of the vertical plate 4, the guide rail 6 is fixedly connected to the inner walls of the left side and the right side of the rectangular groove 5, sliding seats 7 are provided, the cylinder 8 is vertically arranged on the upper end surface of the vertical plate 4, the piston rod of the cylinder 8 extends downwards into the rectangular groove 5, the end part of a piston rod of the cylinder 8 is fixedly connected with the upper end surface of the sliding seat 7, the sliding seat 7 extends outwards to form the rectangular groove 5, the U-shaped mounting seat II 9 is arranged below the sliding seat 7, and the inner and outer sides of the upper end surface of the U-shaped mounting seat II 9 are respectively and vertically fixedly connected with a sliding rod 10, the sliding rod 10 upwards passes through the sliding seat 9 and is connected with the sliding seat in a sliding way, the limiting block 11 is fixedly connected to the top end of the slide rod 10 extending upwards out of the slide seat 9, a spring 12 is sleeved on the slide rod 10 between the slide seat 7 and the U-shaped mounting seat II 9, a rotating shaft 13 is rotatably arranged in an opening of the U-shaped mounting seat II 9 through a bearing, a clamping wheel 14 is sleeved in the middle of the rotating shaft 13, an integrally formed annular convex strip 141 is arranged on the outer arc surface of the clamping wheel 14, and the annular convex strip 141 and the annular groove 31 are on the same vertical plane.
