Description

Technical field:

[0001] The utility model relates to a yarn anti-knot device and belongs to the technical field of textiles. Background technology:

[0002] Yarns are prone to knots during production and processing, and the knots need to be removed during processing. Currently, when knots occur, most workers simply cut off the knotted parts to prevent the knots from entering the next process and affecting the processing of the next process. However, the knots are usually very small and difficult for workers to observe, which can easily cause the knots to enter the next process. In addition, manual removal is very time-consuming and labor-intensive, which greatly reduces the efficiency of yarn processing.

[0003] In response to the above problems, corresponding solutions have emerged in the industry, such as the Chinese authorized utility patent for a yarn anti-knot device with the authorization announcement number CN 216945659U. In the above patent, when a knot appears, the yarn will pull the ring to move, and then the movement of the ring will drive the guide reset mechanism to move, and then the guide reset mechanism will drive the lifting drive device to start, and then the lifting drive device will drive the cutting knife to move downward, and finally the cutting knife moves downward to cut the yarn, and then the worker only needs to cut on the other side of the knot to remove the knot, which effectively prevents the knot from entering the next process, saves cutting time and workers' labor, and effectively improves the efficiency of yarn processing.

[0004] The above patent has the following problems during use: when a knot is found in the spinning thread, the anti-knot device cuts one end of the knot, and the other side needs to be cut manually by workers, which reduces the smoothness of production. At the same time, the cut yarn will fall everywhere, affecting subsequent production. Summary of the invention:

[0005] The technical problem to be solved by the utility model is to provide a yarn anti-knot device to solve the problems faced in the industry.

[0006] In order to solve the above technical problems, the utility model is implemented through the following technical solutions: a yarn anti-knot device, comprising an anti-knot processing box with a hollow interior, a line inlet and a line outlet are respectively arranged on the left and right sides of the anti-knot processing box, a yarn sensing structure is arranged on the inner side of the anti-knot processing box, the yarn sensing structure is installed on the top of the inner side of the anti-knot processing box, a cutting structure is arranged on the side of the yarn sensing structure, a movable clamping structure is arranged on the inner bottom of the anti-knot processing box, and the movable clamping structure is located between the yarn sensing structure and the cutting structure.

[0028] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0029] As Figures 1 to 12 shown, a yarn anti-knotting device includes an anti-knotting treatment box 1 with a hollow interior. An inlet 101 and an outlet 102 are respectively arranged on the left and right sides of the anti-knotting treatment box 1. A yarn induction structure 2 is arranged inside the anti-knotting treatment box 1. The yarn induction structure 2 is installed at the top inside the anti-knotting treatment box 1. A cutting structure 3 is arranged on the side of the yarn induction structure 2. A moving clamping structure 4 is arranged at the bottom inside the anti-knotting treatment box 1. The moving clamping structure 4 is located between the yarn induction structure 2 and the cutting structure 3.

[0030] As Figures 4 to 9 shown, the yarn induction structure 2 includes a rear support plate 201 in a portal structure. A top fixing plate 202 is arranged at the top of the rear support plate 201. A plurality of first sliding seats 203 are arranged on the side of the rear support plate 201. A first slider 204 is arranged on the first sliding seat 203. A slider connecting plate 205 is arranged on the first slider 204. An insertion hole 206 is arranged in the upper part of the rear support plate 201. An insertion slider 207 is arranged in the insertion hole 206. A double-axis cylinder 208 is arranged at the end of the insertion slider 207. Yarn baffles 209 are respectively arranged on the cylinder shafts of the double-axis cylinder 208. A plurality of support springs 210 are arranged on the back of the yarn baffle 209. A pressure sensor 211 is arranged between the support springs 210. The support springs 210 and the pressure sensor 211 are also connected to the slider connecting plate 205.

[0031] In order to allow the yarn to pass through, further, the yarn baffle 209 is in a plate structure, and a semi-circular groove 212 is arranged on the side of the yarn baffle 209.

[0032] As Figure 10 shown, in order to cut the yarn, further, the cutting structure 3 includes a cutting support seat 301. The cutting support seat 301 is installed at the top inside the anti-knotting treatment box 1. A plurality of cutting cylinders 302 are arranged on the lower surface of the cutting support seat 301. A pair of scissors 303 is arranged on the cylinder shaft of the cutting cylinder 302.

[0033] As Figure 11 and Figure 12 shown, in order to clamp the yarn, further, the moving clamping structure 4 includes a bottom guide rail 401. A bottom slider 402 is arranged on the bottom guide rail 401. A bottom double-axis clamping cylinder 403 is arranged on the bottom slider 402. Clamping plates 404 are arranged on the cylinder shafts of the bottom double-axis clamping cylinder 403.

[0034] In order to remove impurities on the yarn, further, dust removal hairs 103 are provided in the inlet 101 and the outlet 102.

[0035] In order to clean the cut yarn, further, an adsorption hole 104 is provided at the right bottom of the anti-knot treatment box 1, an adsorption box body 105 is arranged outside the adsorption hole 104, and an air suction pump 106 is arranged on the adsorption box body 105.

[0036] During use, first, the yarn to be processed is threaded into the anti-knot treatment box 1 from the inlet 101, passes through the semi-circular groove 212 on the yarn baffle 209 of the yarn induction structure 2, and passes between the clamping plates 404, and finally passes through the outlet 102 for use. In this patent, the two yarn baffles 209 are placed opposite to each other, and the semi-circular grooves 212 on the yarn baffles 209 form a complete circle together. At this time, the diameter of the complete circle is the same as the diameter of the yarn, so that the yarn can just pass through the yarn baffle 209, while the knotted part on the yarn cannot pass through the yarn baffle 209.

[0037] When there is a knot on the yarn, the knotted part will be blocked by the yarn baffle 209. At this time, as the yarn moves, the yarn pulls the yarn baffle 209 through the knotted part, and the yarn baffle 209 will move to the right by inserting the slider 207 and compress the support spring 210 and the pressure sensor 211. The pressure sensor 211 generates a pressure signal during the compression process, and the pressure signal is transmitted to the control device. When the control device detects that the pressure signal reaches the set value, the double-axis cylinder 208 is started at this time. The double-axis cylinder 208 drives the yarn baffle 209 to move to both sides. At this time, the distance between the semi-circular grooves 212 between the yarn baffles 209 becomes larger. At this time, the knotted part on the yarn will pass through between the yarn baffles 209. By detecting the running distance of the knotted part of the yarn by the control device, when the knotted part runs below the cutting structure 3, the yarn stops running at this time.

[0038] When the yarn stops running, the bottom double-axis clamping cylinder 403 is started. The bottom double-axis clamping cylinder 403 drives the clamping plates 404 to clamp the yarn. At this time, one end of the knotted yarn is fixed by the clamping plates 404, and the other end is clamped by the device outside the outlet 102. At this time, the cutting cylinder 302 is started. The cutting cylinder 302 drives the cutting knife 303 to descend and cut the knot on the yarn. The cut yarn will fall into the anti-knot treatment box 1. At this time, the air suction pump 106 is started. The air suction pump 106 adsorbs the cut yarn into the adsorption box body 105, thereby preventing the cut yarn from floating randomly and affecting the subsequent production.

[0039] At this time, the bottom slider 402 is started; the bottom slider 402 slides on the bottom guide rail 401, drives the bottom double-axis clamping cylinder 403 to move through the bottom slider 402. At this time, the bottom double-axis clamping cylinder 403 drives the yarn to move through the clamping plate 404, and moves the yarn to the wire outlet 102, facilitating the subsequent use by users.

[0040] In this patent, the problem in the prior art that when a knot is found in the spun yarn, the anti-knot device cuts one end of the knot, while the other side still needs to be manually cut by workers, which reduces the production fluency, is solved. At the same time, the suction pump sucks away the yarn generated by cutting, solving the problem that the cut yarn will float around and affect the subsequent production in the prior art.

[0041] It should be emphasized that: the above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
