[0006] Furthermore, movable grooves are evenly distributed on the sleeve shaft and penetrate inside and outside. The clamping assembly includes a movable shaft that is slidably connected to the inside of the sleeve shaft. A first spring is arranged between the top of the movable shaft and the top inner wall of the sleeve shaft, and the bottom of the movable shaft is fixedly connected to a top block.
[0007] Furthermore, the clamping assembly also includes an expansion mechanism movably arranged in the movable groove, the expansion mechanism includes a slider fixedly connected to the outer wall of the movable shaft, and the interior of the movable groove is laterally slidably connected to a guide plate, and the cross-section of the guide plate is trapezoidal.
[0008] Furthermore, a slide groove is provided on the inner side of the guide plate, and the other end of the slider is slidably connected inside the slide groove. The expansion mechanism also includes a connecting block fixedly connected to the outer side of the slide groove, and the other end of the connecting block is fixedly connected to the connecting plate.
[0009] Furthermore, a rubber sheet is fixedly connected to the outer side of the connecting plate via a second spring.
[0010] Furthermore, the fan-shaped plates are distributed on the outer wall of the sleeve shaft in a fan-blade shape, and four groups of fan-shaped plates are provided, with gaps between two adjacent groups of fan-shaped plates.
[0011] Furthermore, the tensioning assembly includes a sliding block slidably connected to the inside of the base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The present invention provides a yarn rack for a textile machine for yarn production. In a normal state, the radial distance between the four groups of connecting shafts is small, the top of the ball head is located inside the top groove, and pushes up the movable shaft, so that the four groups of expansion mechanisms are retracted into the movable groove. At this time, the yarn roll can be replaced and installed. After the yarn roll is installed, the yarn on the yarn roll rotates under the traction of the textile machine. During the rotation, a certain friction is generated between the yarn roll and the sleeve shaft, which prompts the sleeve shaft to rotate. During the rotation, the fan-shaped plate on the outer wall of the sleeve shaft causes the radial distance between the four groups of connecting shafts to become large. At this time, the ball head moves downward, and the movable shaft also moves downward under the action of the first spring, and finally the expansion mechanism clamps and fixes the paper tube in the middle of the yarn roll, effectively solving the problem that the yarn roll will rotate during the yarn transportation process and the yarn roll is easy to fall off the yarn rack when the speed is too fast. In addition, when the yarn is pulled, a deceleration effect can be formed between the fan-shaped plate, the connecting shaft and the third spring, which can tighten the yarn.

DETAILED DESCRIPTION
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] In order to solve the technical problem that the yarn roll will rotate during the conveying process and the yarn roll will easily fall off the yarn rack when the speed is too fast, such as Figures 1-9 As shown, the following preferred technical solutions are provided:
[0029] A yarn frame for a textile machine for yarn production includes a frame 1 and yarn seats evenly distributed on the frame 1, and a wire portion 2 corresponding to the yarn seat. The yarn seat includes a base 3 installed on the frame 1 and a sleeve 4 rotatably connected to the top of the base 3. A yarn reel 8 is sleeved on the outside of the sleeve 4, and the yarn reel 8 is in contact with the outside of the sleeve 4. A clamping assembly 5 corresponding to the inner wall of the middle paper tube of the yarn reel 8 is provided inside the sleeve 4. A tensioning assembly 7 is provided inside the base 3. Fan-shaped plates 6 are evenly distributed on the lower outer edge of the sleeve 4, and the fan-shaped plates 6 correspond to the tensioning assembly 7. The clamping assembly 5 is used to fix the middle paper tube of the yarn reel 8 to prevent it from detaching. The tensioning assembly 7 is used to slow down the sleeve 4 and the fan-shaped plate 6 to keep the yarn in a taut state during transportation.
[0030] The sleeve shaft 4 is evenly distributed with movable grooves 41 running through the inside and outside. The clamping assembly 5 includes a movable shaft 52 that is slidably connected to the inside of the sleeve shaft 4. A first spring 51 is provided between the top of the movable shaft 52 and the top inner wall of the sleeve shaft 4. The bottom of the movable shaft 52 is fixedly connected to a top block 53.
[0031] The clamping assembly 5 also includes an expansion mechanism 54 movably arranged in the movable groove 41. The expansion mechanism 54 includes a slider 541 fixedly connected to the outer wall of the movable shaft 52. The interior of the movable groove 41 is laterally slidably connected to a guide plate 542. The cross-section of the guide plate 542 is trapezoidal. A slide groove 543 is provided on the inner side of the guide plate 542. The other end of the slider 541 is slidably connected to the inside of the slide groove 543. The expansion mechanism 54 also includes a connecting block 544 fixedly connected to the outside of the slide groove 543. The other end of the connecting block 544 is fixedly connected to a connecting plate 545. The outer side of the connecting plate 545 is fixedly connected to a rubber sheet 547 through a second spring 546. Under the elastic action of the first spring 51, the slide groove 543 has a force to move downward, so that the slider 541 on the outer wall of the movable shaft 52 is located below the inside of the slide groove 543. At this time, the rubber sheet 547 is in contact with the inner wall of the paper tube in the middle of the yarn reel 8 to prevent the yarn reel 8 from detaching.
[0032] The sector plates 6 are distributed on the outer wall of the sleeve shaft 4 in a fan-blade shape, and four groups of sector plates 6 are provided, with gaps between two adjacent groups of sector plates 6 .
[0033] The tensioning assembly 7 includes a sliding block 71 slidably connected to the inside of the base 3. The sliding blocks 71 are provided with eight groups and are divided into two layers, an upper layer and an lower layer. A connecting shaft 73 is fixedly connected between the two corresponding sliding blocks 71. The connecting shaft 73 corresponds to the outer wall of the fan-shaped plate 6. A third spring 72 is provided between the sliding block 71 and the inner side wall of the base 3. The tensioning assembly 7 also includes a movable block 75 slidably connected to the inside of the base 3. The inner side of the sliding block 71 located at the lower inside of the base 3 is rotatably connected to the rotating frame 74. The other end of the rotating frame 74 is rotatably connected to the movable block 75. The top of the movable block 75 is fixedly connected to a connecting rod 76, and the top of the connecting rod 76 is fixedly connected to a ball head 77.
[0034] The bottom of the top block 53 is provided with a top groove 531, which corresponds to the ball head 77. When the clamping assembly 5 inside the sleeve shaft 4 fixes the yarn roll 8, the yarn roll 8 drives the sleeve shaft 4 to rotate through the clamping assembly 5 during the conveying process, and the sleeve shaft 4 drives the fan-shaped plate 6 to rotate. Figure 8 As shown, the sector plate 6 rotates clockwise, and the connecting shaft 73 is always attached to the outer wall of the sector plate 6 under the action of the sliding block 71 and the third spring 72. The range of the connecting shaft 73 on the outer wall of the sector plate 6 is shown as channel A. At this time, the spacing between the four groups of connecting shafts 73 is large, the ball head 77 does not contact the top block 53, and the clamping assembly 5 is still in the clamping state. When the yarn reel 8 stops conveying yarn, as shown in FIG. Figure 9 As shown, the connecting shaft 73 approaches the inside under the action of the third spring 72, and the connecting shaft 73 is inserted into the gap between the two adjacent groups of fan-shaped plates 6. At this time, the ball head 77 moves upward to approach the top block 53, and lifts the top block 53, and the movable shaft 52 moves upward, so that the expansion mechanism 54 leaves the inner wall of the middle paper tube of the yarn reel 8. At this time, it is not in a clamping state, that is, during the yarn conveying process on the yarn reel 8, the clamping assembly 5 can clamp and fix the yarn reel 8. When the yarn reel 8 stops conveying, the clamping assembly 5 no longer clamps and fixes it, which makes it convenient to remove and replace the yarn reel 8.
[0035] Specifically, under normal conditions, the fan plate 6 and the connecting shaft 73 are as follows: Figure 9 As shown, under the action of the third spring 72, the radial distance between the four groups of connecting shafts 73 is small, the top of the ball head 77 is located inside the top groove 531, and the movable shaft 52 is pushed upward, so that the four groups of expansion mechanisms 54 are retracted into the movable groove 41. At this time, the yarn reel 8 can be replaced and installed. After the yarn reel 8 is installed, the yarn on the yarn reel 8 rotates under the traction of the textile machine. During the rotation, a certain amount of friction is generated between the yarn reel 8 and the sleeve shaft 4, which prompts the sleeve shaft 4 to rotate. During the rotation, the fan-shaped plate 6 on the outer wall of the sleeve shaft 4 is in a state with respect to the connecting shaft 73 as shown in FIG. Figure 8As shown, the radial distance between the four groups of connecting shafts 73 is large. At this time, the ball head 77 moves downward, and the movable shaft 52 also moves downward under the action of the first spring 51, and finally the expansion mechanism 54 clamps and fixes the paper tube in the middle of the yarn roll 8.
