AI Technical Summary
In existing yarn feeders, the rigid connection between the yarn and the ceramic plate and antistatic rubber sheet increases friction, which cannot buffer the vibration and impact of the yarn, making it prone to yarn breakage. Furthermore, the yarn cannot be automatically adjusted according to changes in yarn tension, increasing the risk of yarn breakage.
An adaptive buffer assembly is adopted, including a first filter sheet that is elastically installed and a second filter sheet that is fixed. Through the cooperation of a sliding rod and a spring, the position is automatically adjusted when the yarn tension changes, so as to alleviate the pressure fluctuation of the yarn and reduce the risk of yarn breakage.
It effectively absorbs vibration and impact during yarn feeding, protects the yarn from damage, reduces the risk of yarn breakage due to excessive pressure, and improves yarn quality stability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile equipment, specifically a yarn filtering device for a yarn feeder. Background Technology
[0002] In the yarn weaving process, to prevent yarns of varying diameters from mixing in the fabric and affecting its quality, a yarn filter is installed before the yarn enters the feeding wheel to filter the yarn diameter. Yarns filtered by the yarn filter are generally of uniform thickness, which helps improve the quality of spinning and weaving.
[0003] For example, a Chinese patent discloses a yarn filtering device for a yarn feeder, with application number CN201920157646.9. It includes: a plate, a first yarn filtering assembly disposed in the middle of the plate, and a second yarn filtering assembly disposed at the bottom of the plate. The first yarn filtering assembly includes a knob, a rotating shaft, and a yarn clearing plate. The knob and the yarn clearing plate both protrude from the plate. The second yarn filtering assembly includes a first fixing plate and a second fixing plate. A ceramic plate is disposed above the first fixing plate, and an antistatic rubber sheet is disposed above the second fixing plate. This patent achieves a dual yarn filtering function through the first and second yarn filtering assemblies. The yarn rubs against the yarn clearing plate, the ceramic plate, and the antistatic rubber sheet, resulting in a more excellent yarn filtering effect.
[0004] However, because the ceramic plate, antistatic rubber sheet and yarn are rigidly connected, the friction increases when filtering impurities from the yarn, which cannot play a buffering role. As a result, it cannot absorb the vibration and impact force during the operation of the yarn, making it easy to break the yarn. Furthermore, it cannot automatically adjust its position according to the changes in yarn tension, and cannot reduce the fluctuation of pressure on the yarn, increasing the risk of the yarn breaking due to excessive pressure. Utility Model Content
[0005] The purpose of this utility model is to provide a yarn filter device for a yarn feeder, in order to solve the problems mentioned in the background art, which are that because the ceramic plate, antistatic rubber sheet and yarn are rigidly connected, the friction increases when filtering impurities on the yarn, and cannot play a buffering role. As a result, the device cannot absorb the vibration and impact force during the yarn's operation, making it easy for the yarn to break. Furthermore, the device cannot automatically adjust its position according to changes in yarn tension, and cannot mitigate the fluctuations in pressure on the yarn, thus increasing the risk of the yarn breaking due to excessive pressure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This utility model proposes a yarn filter device for a yarn feeder;
[0015] By setting an adaptive buffer component, during the yarn filtering process, since the first filter sheet is elastically installed and the second filter sheet is fixed, when vibration and impact are generated during yarn feeding, the first filter sheet drives the connector to slide on the sliding rod, thereby compressing the spring sleeved on the sliding rod. The elastically installed first filter sheet can automatically adjust its position according to the change of yarn tension, thereby alleviating the pressure fluctuations on the yarn. When the yarn tension increases, the elastically connected first filter sheet can slightly retract, reducing the risk of yarn breakage caused by sudden excessive pressure. It can absorb the vibration and impact generated during yarn feeding, further protecting the yarn from damage. Attached Figure Description

[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 Figures 1 to 6 This utility model provides a technical solution: a yarn filter device for a yarn feeder;
[0025] Example 1:
[0026] To prevent yarn breakage during the filtering process, a second filter sheet 7 is fixedly installed on the right end of the upper surface of the base plate 2. An adaptive buffer assembly 6 is provided on the left end of the upper surface of the base plate 2. The adaptive buffer assembly 6 includes: a mounting frame 601, with two symmetrically arranged sliding rods 602 fixedly installed on the inner side of the mounting frame 601; a connector 604, with two through holes 605 on the inner surface of the connector 604 that match the sliding rods 602; a spring 603 fitted at the connection between the outer surface of the sliding rod 602 and the connector 604; a connecting rod 606 fixedly installed on the side of the connector 604 away from the spring 603; and a first filter sheet 607 fixedly installed on the end of the connecting rod 606 away from the connector 604. The yarn sheet 607 is elastically installed. Since the first filter yarn sheet 607 is elastically installed and the second filter yarn sheet 7 is fixed, when vibration and impact are generated during yarn feeding, the first filter yarn sheet 607 drives the connector 604 to slide on the sliding rod 602, thereby compressing the spring 603 sleeved on the sliding rod 602. The elastically installed first filter yarn sheet 607 can automatically adjust its position according to the change of yarn tension, thereby alleviating the pressure fluctuations on the yarn. When the yarn tension increases, the elastically connected first filter yarn sheet 607 can slightly retract, reducing the risk of yarn breakage caused by sudden excessive pressure. It can absorb the vibration and impact generated during yarn feeding and further protect the yarn from damage.
[0027] Working principle: In actual use, the mounting plate is fixed to the textile machine through the first threaded hole 4 inside the ear plate 3. Then, when feeding yarn of different specifications, the filter plate 9 is rotated by rotating the shaft 8. A suitable yarn hole 10 is selected, and the nut 13 is fixed to the shaft 8 through the internal thread 12, thereby limiting the filter plate 9 and preventing its rotation. During the yarn filtering process, since the first filter plate 607 is elastically installed and the second filter plate 7 is fixed, when vibration and impact occur during yarn feeding, the filter plate 9 is stopped by the rotational force of the internal thread 12. The first filter sheet 607 drives the connector 604 to slide on the sliding rod 602, thereby compressing the spring 603 sleeved on the sliding rod 602. The elastically installed first filter sheet 607 can automatically adjust its position according to the change of yarn tension, thereby alleviating the pressure fluctuations on the yarn. When the yarn tension increases, the elastically connected first filter sheet 607 can slightly retract, reducing the risk of yarn breakage caused by sudden excessive pressure. It can absorb the vibration and impact generated during yarn feeding, further protecting the yarn from damage.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
