[0002] The yarn is fed into the weaving area as required. The yarn feeder controls the yarn length or maintains consistent yarn tension, ensuring the woven fabric meets production requirements. Most yarn feeders have a yarn breakage alarm and shutdown function. Depending on their function and application, they can be categorized as active yarn feeders, semi-passive yarn feeders, passive yarn feeders, multi-color yarn feeders, spandex yarn feeders, etc. The yarn feeder bearing is a crucial component; however, the current assembly method for the yarn feeder roller bearings has the following shortcomings in use:

[0003] The existing assembly methods for yarn feeder bearings on the market are mostly manual assembly using jigs. This process is time-consuming and labor-intensive, with high labor intensity and labor costs, which cannot guarantee production efficiency and results in unsatisfactory performance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model discloses a yarn feeder bearing assembly device, including a pressure bearing assembly 1. The pressure bearing assembly 1 includes a base plate 11, a fixing plate 12 is fixedly disposed on the top of the base plate 11, a pressure bearing cylinder 13 is disposed on the top of the fixing plate 12, a pressure bearing rod 14 is disposed at the output end of the pressure bearing cylinder 13, and a positioning plate 18 is disposed on the top of the base plate 11 directly below the pressure bearing rod 14.

[0025] Specifically, a support plate 16 is fixedly installed on the top of the base plate 11 for placing the bearing base 2. A central bearing 21 is installed inside the bearing base 2. The top of the positioning plate 18 extends into the bottom of the bearing base 2. The positioning plate 18 is coaxially arranged with the bearing base 2 and the central bearing 21. A positioning shaft 181 with its top end extending through to the top of the central bearing 21 is provided at the center of the top of the positioning plate 18. The bearing base 2 to be assembled with the central bearing 21 is placed on the support plate 16. The bottom of the bearing base 2 is provided with a groove that fits into the positioning plate 18, so that after the bearing base 2 is fitted onto the positioning plate 18, the bearing base 2 and the positioning plate 18 remain coaxially arranged. At the same time, the positioning shaft 181 extends to the top of the bearing base 2, and the central bearing 21 is fitted onto the positioning shaft 181, so that the bottom of the central bearing 21 is opposite to the top of the bearing base 2, making the central bearing 21, the positioning shaft 181, and the positioning plate 18 coaxially arranged.

[0026] Specifically, the bearing rod 14 is provided with a clearance hole 141 corresponding to the positioning shaft 181. The bottom of the bearing rod 14 is also provided with an inner convex ring 142 corresponding to the inner ring of the central bearing 21 and an outer convex ring 143 corresponding to the outer ring of the central bearing 21. When the bearing cylinder 13 is activated, the bearing rod 14 is driven to descend. The clearance hole 141 is sleeved with the positioning shaft 181, the inner convex ring 142 is opposite to the inner ring of the central bearing 21, and the outer convex ring 143 is opposite to the outer ring of the central bearing 21. This makes the pressure on the central bearing 21 more uniform, so that the central bearing 21 is smoothly pressed into the interior of the bearing base 2, completing the assembly.

[0027] Specifically, the top of the support plate 16 is rotatably equipped with at least two rotating shafts 17 located on both sides of the positioning disk 18. One side of the top of each rotating shaft 17 is provided with a pressure block 171 extending to the top of the bearing base 2. The bottom of the end of the pressure block 171 away from the rotating shaft 17 is provided with an arc surface. Only half of the bottom of the end of the pressure block 171 away from the rotating shaft 17 is an arc surface, and the other half is a straight surface. The straight surface contacts the top of the bearing base 2, which can more stably press the bearing base 2. When the bearing base 2 is placed on the support plate 16, the pressure block 171 is rotated so that the arc surface of the pressure block 171 contacts the bearing base 2. As the arc decreases, the straight surface at the bottom of one end of the pressure block 171 contacts the top of the bearing base 2, pressing the top of the bearing base 2 and preventing the top of the bearing base 2 from tilting up on all four sides when assembling the center bearing 21.

[0028] Specifically, a support profile 15 is fixedly installed on the top of the base plate 11, and a fixing plate 12 is fixedly installed on the top of the support profile 15.

[0029] In summary, compared to the manual assembly of the bearing base 2 and the center bearing 21 used in the market, this yarn feeder bearing assembly device uses a bearing pressing cylinder 13 in conjunction with a bearing pressing rod 14 to press the center bearing 21 into the bearing base 2, which is more efficient. Furthermore, the positioning plate 18 and the rotatable pressing block 171 cooperate to ensure the assembly stability of the bearing base 2 and the center bearing 21. The setting of the bearing pressing rod 14 makes the pressure on the center bearing 21 more uniform, improves the product assembly yield, is economical, and has broad application prospects.
