DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model provides Figure 1-4 The tail retaining device of a vortex spinning machine shown in the figure comprises a mounting plate 1, a tail retaining rod 2 is fixedly connected to one side of the inner wall of the mounting plate 1, and the yarn can be hung on the tail retaining rod 2 to perform the tail retaining operation;

[0033] Furthermore, an extrusion mechanism 3 is arranged between the mounting plate 1 and the tail retaining rod 2, and the extrusion mechanism 3 includes: a fixed cylinder 31, a connecting rod 32, an extrusion assembly 33 and a positioning assembly 34, the fixed cylinder 31 is fixedly connected to the top of the mounting plate 1; the connecting rod 32 is slidably and interlacedly connected with the mounting plate 1; the extrusion assembly 33 is arranged at the bottom end of the connecting rod 32, and is used to fix the tail retaining spinning line; the positioning assembly 34 is arranged at the top end of the connecting rod 32, and is used to adjust the position of the extrusion assembly 33.

[0034] Specifically, the extrusion assembly 33 includes: a fixed plate 331, a telescopic plate 332 and a first compression spring 333. The fixed plate 331 is fixedly connected to the bottom end of the connecting rod 32; the telescopic plate 332 is slidably interlaced with the inner cavity of the fixed plate 331; and a plurality of first compression springs 333 are equidistantly located in the inner cavity of the fixed plate 331. One end of the plurality of first compression springs 333 is fixedly connected to the telescopic plate 332, and the other end of the plurality of first compression springs 333 is fixedly connected to the top of the inner wall of the fixed plate 331. The first compression spring 333 is always in a compressed state, so as to provide a stable downward elastic force to the telescopic plate 332, so that when the telescopic plate 332 is used to squeeze the yarn with the tail, the yarn can be stably squeezed under the elastic force, so that the yarn will not separate from the tail-retaining rod 2.

[0035] Furthermore, both sides of the telescopic plate 332 are fixedly connected with limiting blocks 334, and both sides of the inner wall of the fixed plate 331 are provided with limiting grooves. The limiting blocks 334 are slidably and interlaced with the inner cavity of the limiting grooves. The limiting blocks 334 play a limiting role in the telescopic plate 332, so that the telescopic plate 332 can only slide along the limiting grooves under the elastic force of the first compression spring 333.

[0036] Furthermore, the bottom end of the telescopic plate 332 is fixedly connected to a rubber pad 4, and the bottom end of the rubber pad 4 is provided with an anti-skid texture. The provision of the rubber pad 4 increases the friction between the telescopic plate 332 and the yarn, so that when the telescopic plate 332 squeezes and fixes the yarn, the yarn will not move, and the anti-skid texture is serrated, which can ensure that the telescopic plate 332 will not flatten the yarn, thereby ensuring the normal use of the yarn.

[0037] Specifically, the positioning assembly 34 includes: a rotating disk 341, a slider 342, a positioning rod 343 and a second compression spring 344. The rotating disk 341 is fixedly connected to the top of the connecting rod 32. The rotating disk 341 is slidably and interlacedly connected with the inner cavity of the fixed cylinder 31. A plurality of rotating grooves are equidistantly provided at the top of the rotating disk 341. A handle can be formed between the plurality of rotating grooves. The rotating disk 341 can be rotated by the handle so that the rotating disk 341 drives the connecting rod 32 to rotate and can also perform lifting and lowering movements. The plurality of sliders 342 are respectively fixedly connected to both sides of the rotating disk 341. A plurality of sliding grooves are equidistantly provided on the inner wall of the fixed cylinder 31. The cross section of the sliding groove is L-shaped. The sliding blocks 342 slide with the inner cavity of the sliding groove. The insertion connection is through the L-shaped slide groove, and the slider 342 can be inserted into the interior of the slide groove and rotated 45°, so that the slide groove can limit the slider 342 in the vertical direction; the top ends of the inner walls of multiple slide grooves are provided with positioning grooves, one end of the positioning rod 343 is fixedly connected to the slider 342, and the other end of the positioning rod 343 is slidingly inserted and connected with the inner cavity of the positioning groove. When the slider 342 slides to the deep end of the slide groove, the positioning rod 343 and the positioning groove can be inserted, thereby limiting the slider 342 in the horizontal direction, so that the turntable 341 cannot be displaced to ensure stability after fixation; the second compression spring 344 is sleeved on the outside of the connecting rod 32. One end of the second compression spring 344 is fixedly connected to the turntable 341, and the other end of the second compression spring 344 is fixedly connected to the mounting plate 1. The second compression spring 344 is always in a compressed state, thereby providing a stable upward elastic force to the turntable 341. When the slider 342 slides into the interior of the slide groove, the slider 342 can be tightly attached to the top of the inner wall of the slide groove, and the positioning rod 343 and the positioning groove can be inserted to achieve a better positioning effect. The elastic force of the second compression spring 344 can completely pull up the connecting rod 32 and the extrusion assembly 33 for use when retaining the tail.
