Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a guide component and a waste yarn collecting device. Background Art

[0002] Existing rapier looms produce waste yarn during the production process. The waste yarn often drops the weft yarn sandwiched in the waste yarn onto the cloth surface, affecting the quality of the product and also affecting subsequent processing. In this regard, the prior art (CN211814832U) discloses a waste collection mechanism for a rapier loom, comprising a frame, a waste guide assembly, a hemming assembly, and a waste bucket. The frame is provided with a cloth guide roller and a winding roller. The waste guide assembly comprises a guide ring, a first steering ring arranged on the left side of the frame, and a second steering ring arranged on the right side of the frame. The hemming assembly comprises a concentric shaft. A perforation is provided on the side of the frame close to the waste bucket. After the waste yarn is cut on the cloth guide roller, the waste yarn passes through the guide ring and enters the first steering ring, then passes through the second steering ring and passes through the perforation, and is introduced into the collection bucket under the drive of the concentric shaft. However, the guide ring, the first steering ring and the second steering ring of the guide mechanism of this loom are easily affected by resistance and installation angle. When the waste yarn passes through the guide ring, the waste yarn is easily stuck, causing the waste yarn to accumulate and difficult to collect, affecting product quality. Therefore, the waste yarn collecting device of the rapier loom is unreasonable, so it is necessary to provide a guide member and a waste yarn collecting device to solve the above problems.

[0025] The first connection portion 141 is substantially cylindrical in shape. The bottom diameter of the first connection portion 141 is smaller than the middle portion 145 . A threaded portion 144 is provided at the top of the first connection portion 141 .

[0026] The second connecting portion 142 is substantially in the shape of a flat plate. The second connecting portion 142 is provided with four circular limiting holes 143 . The limiting holes 143 pass through the second connecting portion 142 horizontally.

[0027] The rotating assembly 13 includes a body 11 , a first bearing 131 disposed inside the body 11 , and a second bearing 132 disposed inside the body 11 .

[0028] The main body 11 is roughly in the shape of an "I" character, with a first limiting groove 111 formed by the top of the main body 11 recessed toward the center, a second limiting groove 112 formed by the bottom of the main body 11 recessed toward the center, a first mounting hole 114 formed through the center of the main body 11, and a guide edge portion 113 formed by the side of the main body 11 recessed inward.

[0029] The first limiting groove 111 is in the shape of a cylindrical groove. The first limiting groove 111 and the second limiting groove 112 are symmetrical about the center of the main body 11. The first limiting groove 111 and the second limiting groove 112 have the same structure. The first mounting hole 114 is located between the first limiting groove 111 and the second limiting groove 112. The first mounting hole 114 connects the first limiting groove 111 and the second limiting groove 112.

[0030] The first bearing 131 is annular and is disposed in the first limiting groove 111. One side of the first bearing 131 abuts against the bottom surface of the locking nut 12, and the other side abuts against the bottom surface of the first limiting groove 112. The second bearing 132 is disposed in the second limiting groove 112. One side of the second bearing 132 abuts against the top surface of the second limiting groove 112, and the other side abuts against the top of the intermediate portion 145. The first bearing 131 and the second bearing 132 have the same structure and are symmetrical about the center of the body 11.

[0031] The locking nut 12 is disposed in the first limiting groove 141 . The bottom end of the locking nut 12 abuts against the first bearing 131 , and the threaded portion 144 is threadedly connected to the locking nut 12 .

[0032] The working process of the guide member 10 of the present invention will be described below with reference to the accompanying drawings:

[0033] When the guide member 10 is in use, the first bearing 131 is engaged with the first limiting groove 111, the second bearing 132 is engaged with the second limiting groove 112, the first connecting portion 141 passes through the second bearing 132, the first mounting hole 114, and the first bearing 131 in the first limiting groove 111 in sequence and is engaged with the first mounting hole 114, the locking nut 12 is threadedly connected to the threaded portion 144, so that the main body 11 is fixed to the upper end of the adjustment bracket 14, and the second connecting portion 142 is fixed to the frame 20. When fixed, the guide member 10 is adjusted up and down by using different limiting holes 143.

[0034] Therefore, the guide member 10 of the present invention has at least the following beneficial effects:

[0035] When in use, the waste yarn passes through the guide member 10, so that the waste yarn is kept at a certain distance from the cloth surface and will not be tightly attached, thereby preventing the waste yarn from falling on the cloth surface. The guide edge portion 113 on the guide member 10 is an open groove. When the waste yarn is wrapped around the guide edge portion 113, it is not easy to shift. The waste yarn is pulled and wrapped around the guide edge portion 113. The first bearing 131 and the second bearing 132 rotate relative to the main body 11, and the guide edge portion 113 and the waste yarn are relatively stationary, thereby avoiding thread jamming and reducing the impact on subsequent processing.

[0036] Please refer to Figure 5 The utility model also provides a waste yarn collecting device 1, which includes the above-mentioned guide member 10.

[0037] The waste yarn collecting device 1 further includes a frame 20 , scissors 30 , guide assemblies 40 arranged on both sides of the frame 20 , a traction member 50 arranged on the right side of the frame 20 , and a collection box 60 .

[0038] The guide assembly 40 is composed of two guide members 10 , one of which is arranged on the left side of the frame 20 and the other is arranged on the right side of the frame 20 . The two guide members 10 are symmetrical about the central axis of the frame 20 .

[0039] The waste yarn is wound onto the traction member 50 through the guide portion 113 on the guide member 10 . The collecting box 60 is arranged on the right side of the traction member 50 . The waste yarn enters the collecting box 60 after being guided by the traction member 50 .

[0040] Under the traction action of the traction member 50, the waste yarn trimmed by the scissors 30 is pulled to the guide member 10, the waste yarn wraps around the guide edge portion 113 and is engaged with the guide member 10, and the waste yarn is rolled up by the traction member 50 to the collection box 60, and the waste yarn in the collection box 60 is then processed uniformly.
