[0022] Specifically, the limiting assembly includes a rotating block 11 and a linkage unit, the rotating block 11 is rotatably connected to the inner side of the fixed yarn drum 4, the outer side of the fixed yarn drum 4 is equidistantly fixedly connected with an arc block 12, the inner wall of the fixed yarn drum 4 is equidistantly slidably connected with a slide plate 13, the rotating block 11 can be rotated forward or reversed through the linkage unit, the linkage unit includes a rotating rod 10, the rotating rod 10 is rotatably connected to the outer side of the rotating block 11 and is located inside the fixed yarn drum 4, the interior of the fixed yarn drum 4 is provided with disassembly grooves 14 on both sides close to the block 6, the interior of the disassembly groove 14 is slidably connected with a slider 15, one side of the slider 15 extends to the interior of the disassembly groove 14 and is fixedly connected to the slider 15, the interior of the disassembly groove 14 and a first spring 16 is provided on one side of the slider 15, the outer side of the rotating rod 10 is fixedly connected with a gear 18, the outer side of the two sliders 15 are fixedly connected with racks 17, and the gear 18 is respectively meshed with the two racks 17.

[0023] The first spring 16 is pressed against the first support 14 and the second support 14 is pressed against the first support 14, and the first support 14 is pressed against the first support 14. The rotating block 11 drives the external arc block 12 to push the slide plate 13, so that the slide plate 13 drives the support plate 5 to move outward until the yarn tube is tensioned, and the yarn tube can be fixed. At the same time, the yarn tube can be limited by the clamping block 6 to prevent the yarn tube from being thrown out during the rotation. When the yarn tube needs to be replaced, the rotating wheel 19 can drive the clamping block 6 to move toward the inside of the fixed yarn tube 4 through the above principle, and at the same time drive the arc block 12 to cancel the limit of the slide plate 13 on the support plate 5, so that the yarn tube can be conveniently disassembled and replaced. This device can not only stably install the yarn tube, but also improve the stability of the yarn tube at work. The disassembly and assembly are convenient and fast, and the work efficiency is improved. When the yarn is sent, the yarn is passed through the bottom of the pressure rod 9, and the yarn can be tightened by the rebound force of the second spring 21. The yarn is always controlled at a suitable tension, thereby preventing the yarn from loosening during yarn feeding, causing the yarn to be stuck or knotted on the yarn feeding frame, thereby affecting the work efficiency, and improving the final product quality and elasticity.

[0024] Specifically, the tensioning assembly includes a fixing ring 20, which is fixedly connected to the upper part of the outside of the fixing rod 7, a second spring 21 is arranged outside the fixing rod 7 and between the fixing ring 20 and the sliding column 8, and a limiting rod 22 is fixedly connected to the outside of the support frame 2 and on both sides of the fixing rod 7, and the end of the outside of the pressure rod 9 away from the sliding column 8 is slidably connected to the outside of the limiting rod 22.

[0025] Through the above technical solution, the tensioning component provided can provide tension control for the yarn and improve the yarn feeding stability.

[0026] Specifically, one end of the rotating rod 10 extends to the outside of the yarn fixing cylinder 4 and is fixedly connected to a rotating wheel 19. The outside of the rotating wheel 19 is provided with a knurling pattern, and the outside of the supporting plate 5 is an arc-shaped structure.

[0027] Through the above technical solution, the knurled pattern can increase the friction between the rotating wheel 19 and the staff's hands to prevent slipping.

[0029] Through the above technical solution, by controlling the output end of the hydraulic cylinder to extend or contract, the lifting plate 23 and the fixed column 1 can be driven to be raised and lowered to any height, thereby improving the flexibility and adaptability of use. The universal wheel 26 set at the bottom of the base 24 can push the device to any work location.

[0030] When in use, when it is necessary to install the yarn tube, the yarn tube is sleeved on the outer side of the corresponding fixed yarn tube 4, and then pushed inward, so that one side of the yarn tube pushes the arc surface of the outer side of the block 6, pushing it into the inside of the disassembly groove 14, and squeezing the first spring 16 at the same time, until the block 6 is completely moved into the disassembly groove 14, and the yarn tube can continue to be pushed into the inside of the fixed yarn tube 4. In the process of the block 6 moving into the disassembly groove 14, the corresponding rack 17 can be driven to move by the slider 15, so that the rack 17 drives the gear 18 to rotate through the meshing relationship, and the gear 18 drives the arc block 12 away from the slide plate 13 after rotating, so that the The sliding plate 13 is pushed by the sliding plate 13, and the supporting plate 5 can slide arbitrarily inside the yarn-fixing tube 4, so the movement of the yarn tube will not be affected, until the yarn tube is completely pushed to the outside of the yarn-fixing tube 4, and the block 6 is separated from the squeezing force of the yarn tube, so that the block 6 is ejected to the outside of the yarn-fixing tube 4 under the rebound force of the first spring 16, and the gear 18 is driven to rotate in the opposite direction, thereby driving the rotating block 11 to rotate, so that the rotating block 11 drives the external arc block 12 to push the sliding plate 13, so that the sliding plate 13 drives the supporting plate 5 to move outward, until the yarn tube is tightened, and the yarn tube can be fixed. At the same time, the yarn can be tightened by the block 6. The yarn drum is limited to prevent the yarn drum from being thrown out during the rotation. When the yarn drum needs to be replaced, the rotating wheel 19 can drive the clamping block 6 to move toward the inside of the fixed yarn drum 4 through the above principle, and at the same time drive the arc block 12 to cancel the limitation of the slide plate 13 on the support plate 5, so that the yarn drum can be conveniently disassembled and replaced. This device can not only stably install the yarn drum, but also improve the stability of the yarn drum during work. The disassembly and assembly are convenient and quick, and the work efficiency is improved. When the yarn is sent, the yarn is passed through the bottom of the pressure rod 9, and the yarn can be tightened by the rebound force of the second spring 21, so that the yarn is always controlled at an appropriate tension. , thereby preventing the yarn from loosening during yarn feeding, causing the yarn to get stuck or tangled on the yarn feeding frame and thus affecting work efficiency, thereby improving the final product quality and elasticity. The tensioning component provided can provide tension control for the yarn and improve the stability of yarn feeding. The knurled pattern provided can increase the friction between the rotating wheel 19 and the staff's hands to prevent slipping. By controlling the output end of the hydraulic cylinder to extend or contract, the lifting plate 23 and the fixed column 1 can be driven to be raised and lowered to any height, thereby improving the flexibility and adaptability of use. The universal wheel 26 provided at the bottom of the base 24 can push the device to any work location.
