Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinning, and in particular to a yarn defect removal device and a spinning equipment having the device. Background Technology
[0002] During the operation of spinning equipment, after the yarn exits from the spinning cup, it needs to be wound onto the yarn roll. However, defects such as neps and short, thick sections often exist on the surface of the yarn, affecting the quality of the finished product. Traditional defect removal devices mostly use a shearing mechanism to directly cut off the defective sections. However, after being cut, the yarn is prone to detaching from the spinning channel, requiring manual intervention to re-thread the yarn, resulting in production interruptions and reduced efficiency. Utility Model Content

[0006] An adsorption mechanism, located on the side of the shearing mechanism away from the spinning channel, adsorbs the yarn in the spinning channel into the shearing channel, enabling the shearing mechanism to cut off the defective parts of the yarn; and
[0007] The retrieval mechanism is located upstream of the spinning channel relative to the shearing channel, and generates airflow in the spinning channel in a first direction, causing the portion of the yarn located in the shearing channel to re-enter the spinning channel.

[0012] Preferably, a detector is disposed at the upstream end of the spinning channel relative to the retrieval mechanism, the detector having a detection end coaxial with the wind tunnel and through which the yarn passes.
[0013] A spinning machine employs a yarn defect removal device, comprising:

[0028] like Figure 1 As shown, the spinning equipment described in this application is used to drive the yarn 100 spun in the spinning cup 8 into the top spool 6 for winding. During this process, it is necessary to remove defects such as knots and short, thick knots on the yarn 100. Therefore, this application provides a yarn defect removal device.
[0029] The present invention will be further described in detail below with reference to specific embodiments:
[0030] Combination Figure 2 and Figure 3 As shown, a yarn defect removal device is configured in conjunction with a spinning channel 1. The spinning channel 1 is constructed as a portion of the path traversed by the yarn 100 along a first direction during its journey from the spool 6 to the spinning cup 8. The yarn defect removal device includes a shearing mechanism 2 and an adsorption mechanism 3. The shearing mechanism 2 is located on one side of the spinning channel 1, forming a shearing channel 21 communicating with the spinning channel 1. The adsorption mechanism 3 is configured in conjunction with the shearing mechanism 2, located on the side of the shearing mechanism 2 away from the spinning channel 1. By generating negative pressure, the adsorption mechanism 3 draws the yarn 100 from the spinning channel 1 into the shearing channel 21, allowing the shearing mechanism 2 to cut the yarn 100 that has entered, thereby removing the defective portion of the yarn 100. In this embodiment, the shearing mechanism 2 is a pair of scissors.
[0031] In order to enable the cut yarn 100 to re-enter the spinning cup 8 for continued spinning, this application also provides a retrieval mechanism 4. The retrieval mechanism 4 is located at the upstream end of the spinning channel 1 relative to the shearing channel 21, and can generate airflow in the spinning channel 1 in a first direction, so that the portion of the yarn 100 located in the shearing channel 21 re-enters the spinning channel 1.
[0032] Specifically, in combination Figures 4-6As shown, the retrieval mechanism 4 is connected to an external air source and has a wind tunnel 43 through which the yarn 100 passes. The end of the wind tunnel 43 away from the shearing mechanism 2 forms an opening for the yarn 100 to enter and exit radially. The interior of the retrieval mechanism 4 is hollow, forming a chamber 42. One end of the chamber 42 is connected to an interface 47 that can connect to an external air source, and the other end is arranged around the wind tunnel 43 as an air outlet 46.
[0033] Furthermore, the retrieval mechanism 4 includes a first portion 44 and a second portion 45 formed by splicing together, with a chamber 42 formed between the inner wall of the first portion 44 and the outer wall of the second portion 45. The top end of the second portion 45 extends radially toward the first portion 44, closing the top end of the chamber 42, and a gap is formed between the bottom end of the first portion 44 and the bottom end of the second portion 45, which is configured as an air outlet 46. In this embodiment, the air outlet 46 is U-shaped.
[0034] The bottom end of the wind tunnel 43, away from the opening, is constructed as the intersection of the spinning channel 1 and the shearing channel 21. When the external air source is activated, the U-shaped wind generated by the air outlet 46 can blow the portion of the yarn 100 located in the shearing channel 21 into the spinning channel 1.
[0035] The detection of defects on yarn 100 is done through methods such as... Figure 2 and Figure 3 The detector 9 shown is located at the upstream end of the spinning channel 1. The detector 9 has a detection end that is coaxial with the wind tunnel 43 and through which the yarn 100 passes.
[0036] like Figure 1 As shown, the spinning equipment described in this application further includes a guiding unit 5, which is configured in conjunction with the yarn roll 6, and includes a guide nozzle 51 and a guide rod 52. The guide rod 52 is arranged parallel to the length direction of the yarn roll 6. The guide nozzle 51 is provided with a slot, and the yarn 100 is slidably connected to the slot, so that the guide nozzle 51 can drive the yarn 100 to reciprocate along the guide rod 52, so that the yarn 100 can be evenly wound on the yarn roll 6.
[0037] When the guide nozzle 51 carries the yarn 100, it imparts a horizontal motion component to the yarn 100, which is proportional to the distance between the guide nozzle 51 and the line connecting the spinning cup 8 and the spool 6. However, the speed at which the spinning cup 8 spins the yarn 100 is constant and equal to the take-up speed of the spool 6, so this additional horizontal motion component will cause the yarn 100 to break. Therefore, the spinning equipment also includes a tensioning mechanism 7, which includes a tensioning base 72 on which a tensioning wheel 71 is elastically mounted. The tensioning wheel 71 is slidably connected to the yarn 100. The portion of the yarn 100 that abuts against the tensioning wheel 71 is a compensation section, which tends to bend under the action of elasticity. When the horizontal motion component of the yarn 100 increases, the yarn 100 overcomes the elasticity of the compensation device, causing the compensation section to become straight, thus compensating for the motion component; while when the motion component decreases, the compensation device causes the compensation section to bend, causing the part of the yarn 100 other than the compensation section to become straight, and preparing for compensation on the next side.
[0038] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
