Description

Technical Field

[0001] The invention belongs to the technical field of textile warp knitting, and in particular relates to a warp knitting lint clearing device. Background Art

[0002] Warp knitting is the process of weaving yarn into fabric along the longitudinal direction (warp direction). It has been proven that warp knitting can improve the speed of textile production and product quality, and is therefore widely used in textile production. However, an investigation of the warp knitting production records and the obtained fabrics found that there were problems of broken threads and pilling on the fabric during the warp knitting process, which greatly affected the orderly production and product quality of warp knitting. Research has found that since the yarn is made by twisting and stretching the processed fibers using ring spinning, air spinning or other spinning techniques, there are some fiber fluffs on the surface of the yarn that are not completely twisted in. When the yarn passes through the yarn guide needle of the warp knitting equipment during warp knitting, it will rub against the needle hole of the yarn guide needle to cause the fiber fluff to fall off. The fiber fluff is easy to gather at the needle hole to form pills, and smaller pills will form pills on the surface of the fabric as the yarn passes through the needle hole, affecting the quality. When the larger pills cannot pass through the needle hole, the fiber fluff on the subsequent yarn is easy to get stuck at the pills formed, causing the thread to break.

[0003] At present, in order to prevent the fiber fluff on the yarn from affecting the warp knitting production, the existing technology mostly adopts the method of cleaning the fiber fluff before the yarn is input into the warp knitting equipment, for example: improving the yarn splitting reed in front of the yarn input port of the warp knitting equipment, further reducing the gap of the yarn splitting reed, and using the yarn splitting reed to clean the fiber fluff on the yarn when the yarn passes through the gap of the yarn splitting reed, or installing a negative pressure suction device on the yarn splitting reed, and using airflow to suck away the fiber fluff on the yarn. However, since the gap of the yarn splitting reed needs to be set to a certain length in the vertical direction, otherwise, there will be a situation where the hair balls gather at the yarn guide needle and cause the thread to break, making it difficult to clean the fiber fluff on the upper and lower sides of the yarn. In addition, when the fiber fluff on the yarn is sucked away by the airflow, since some of the fiber fluff is still connected to the yarn, it is difficult to completely suck away the fiber fluff, resulting in fiber fluff still existing on the yarn after cleaning.

[0025] Warp knitting is the process of weaving yarn into fabric along the longitudinal direction (warp direction). It has been proven that warp knitting can improve the speed of textile production and product quality, and is therefore widely used in textile production. However, an investigation of the warp knitting production records and the obtained fabrics found that there were problems of broken threads and pilling on the fabric during the warp knitting process, which greatly affected the orderly production and product quality of warp knitting. Research has found that since the yarn is made by twisting and stretching the processed fibers using ring spinning, air spinning or other spinning techniques, there are some fiber fluffs on the surface of the yarn that are not completely twisted in. When the yarn passes through the yarn guide needle of the warp knitting equipment during warp knitting, it will rub against the needle hole of the yarn guide needle to cause the fiber fluff to fall off. The fiber fluff is easy to gather at the needle hole to form pills, and smaller pills will form pills on the surface of the fabric as the yarn passes through the needle hole, affecting the quality. When the larger pills cannot pass through the needle hole, the fiber fluff on the subsequent yarn is easy to get stuck at the pills formed, causing the thread to break.

[0026] At present, in order to prevent the fiber fluff on the yarn from affecting the warp knitting production, the existing technology mostly adopts the method of cleaning the fiber fluff before the yarn is input into the warp knitting equipment, for example: improving the yarn splitting reed in front of the yarn input port of the warp knitting equipment, further reducing the gap of the yarn splitting reed, and using the yarn splitting reed to clean the fiber fluff on the yarn when the yarn passes through the gap of the yarn splitting reed, or installing a negative pressure suction device on the yarn splitting reed, and using airflow to suck away the fiber fluff on the yarn. However, since the gap of the yarn splitting reed needs to be set to a certain length in the vertical direction, otherwise, there will be a situation where the hair balls gather at the yarn guide needle and cause the thread to break, making it difficult to clean the fiber fluff on the upper and lower sides of the yarn. In addition, when the fiber fluff on the yarn is sucked away by the airflow, since some of the fiber fluff is still connected to the yarn, it is difficult to completely suck away the fiber fluff, resulting in fiber fluff still existing on the yarn after cleaning.

[0027] Based on the above problems, an embodiment of the present invention provides a warp knitting lint clearing device, which is used in conjunction with two scrapers inside the shell through a through hole on the shell, so that the yarn passes through the shell and the fiber lint on both sides of the yarn is removed by the scrapers, and then the rubbing plate, guide rail and driving mechanism are used in conjunction, so that the rubbing plate drives the yarn to rotate around its circumference, so that the scraper completely removes the fiber lint on the yarn, thereby improving the effect of removing the fiber lint on the yarn and avoiding the fiber lint affecting the fabric during warp knitting.

[0028] Reference Figure 1 , Figure 2 , Figure 1 This is a front view of the lint-clearing device of this embodiment. Figure 2 FIG. 2 is a side view of the lint-clearing device of this embodiment. Figure 1 , 2 As shown, a warp knitting lint-clearing device is configured and connected to a warp knitting machine, comprising a housing 1, two scrapers 2 arranged in the housing 1, and a thread twisting assembly. The housing 1 is fixed to the front side of the yarn-dividing reed of the warp knitting machine, and the two scrapers 2 are respectively arranged vertically on the side of the housing 1 away from the yarn-dividing reed. The yarn passes through the housing 1 and then enters the yarn-dividing reed. The thread twisting assembly drives the yarn entering the housing 1 to rotate around its circumference, and the yarn passes between the two scrapers 2 to remove the fiber lint on the yarn near the two sides of the scrapers 2. The thread twisting assembly includes two rubbing plates 3, which are horizontally arranged on the housing 1. On the other side of the interior, the yarn passes between the two rubbing plates 3, and the yarn abuts against the side of the two rubbing plates 3 that are close to each other. The two guide rails 4 are respectively arranged horizontally on the side of the two rubbing plates 3 that are away from each other. The guide rails 4 and the direction in which the yarn passes through the housing 1 are perpendicular to each other. The rubbing plates 3 slide along the guide rails 4, and the guide rails 4 are fixedly connected to the housing 1. The driving mechanism is arranged on the housing 1, and the output ends of the driving mechanism are respectively connected to the two rubbing plates 3, for driving the two rubbing plates 3 to move back and forth in opposite directions, so that the two rubbing plates 3 drive the yarn to rotate around their circumferences.

[0029] The present embodiment proposes a warp knitting lint-clearing device, which is installed on a warp knitting machine and can process the yarn used for warp knitting. The yarn passes through the shell 1 through the through hole 11 before being input into the warp knitting machine, and the two scrapers 2 inside the shell 1 are used to remove the fiber lint on the yarn near the two sides of the scraper 2, and then the driving mechanism is used to drive the rubbing plate 3 to move back and forth on the guide rail 4, so that the rubbing plate 3 drives the yarn to rotate around its circumference, so that the outer side of the yarn can contact the edge of the scraper 2, so that the fiber lint on the yarn is completely removed, avoiding the dead corner where the fiber lint is not removed, improving the effect of removing the fiber lint on the yarn, and avoiding the influence of the fiber lint during warp knitting.

[0030] Reference Figure 5 , Figure 5 FIG. 2 is a cross-sectional view of the lint removal device of this embodiment. Figure 5As shown, the guide rail 4 adopts a guide rod 41 and a connecting block 42. Two guide rods 41 are horizontally provided on the side where the two sliding plates 3 are away from each other. Both ends of the guide rod 41 are fixedly connected to the shell 1. The connecting block 42 is fixed on the side where the two sliding plates 3 are away from each other. The guide rod 41 passes through the connecting block 42 and is slidably connected thereto.

[0031] As a further optimization scheme, in this embodiment, the scraper 2 adopts a circular plate, on which a rotating shaft 20 is horizontally provided and coaxial, one end of the rotating shaft 20 is fixedly connected to the circular plate, and a rotating power unit is provided on the shell 1, and the output shaft of the rotating power unit is connected to the other end of the rotating shaft 20.

[0032] In this embodiment, the scraper 2 is set as a circular plate, and the scraper 2 of the circular plate is driven to rotate by the rotating power unit and the rotating shaft 20, so that the fiber fluff on the yarn is removed by using two rotating circular plates. The fiber fluff still connected to the yarn can be actively scraped off, further improving the effect of removing the fiber fluff on the yarn. At the same time, the scraped fiber fluff quickly moves away from the yarn, effectively preventing the removed fluff from gathering to form hair balls.

[0033] Reference Figure 3 , Figure 3 FIG. 2 is a cross-sectional view of the AA section of the lint removal device of this embodiment. Figure 3 As shown, as a further optimization scheme, in this embodiment, the two circular plates are arranged in a V shape, and the spacing between the two scrapers 2 gradually decreases from the side close to the warp knitting machine to the other side. The two rotating shafts 20 on the two circular plates are replaced by a transmission shaft, and a mounting hole 21 is coaxially opened on the circular plate. The transmission shaft passes through the mounting hole 21 and is connected to the circular plate through a ball cage universal joint 22. One end of the transmission shaft is rotatably connected to the shell 1, and the other end is connected to the output shaft of the rotating power unit.

[0034] In this embodiment, the scrapers of the two circular plates are arranged in a V shape, and one transmission shaft is used to replace the two rotating shafts 20, so that the two circular plates can rotate synchronously, thereby improving the scraper 2's cleaning effect on the fiber fluff on the yarn. In addition, the two circular plates arranged in a V shape can further move the scraped fiber fluff away from the yarn quickly, further improving the cleaning effect of the fiber fluff on the yarn.

[0035] The ball cage universal joint in this embodiment is referred to as Figure 8 , 9 , Figure 8 It is a front view of the ball cage universal joint of this embodiment, Fig. 9 2 is a cross-sectional view of the ball cage universal joint of this embodiment, as shown in FIG. Figure 8 , 9As shown, the transmission shaft passes through the through hole on the inner side of the ball cage universal joint 22 and is fixedly connected thereto, and the outer side of the ball cage universal joint 22 passes through the mounting hole 21 on the circular plate and is fixedly connected thereto. The ball cage universal joint 22 is used to rotate the circular plate while being able to tilt a certain angle so that the two circular plates are in a V shape.

[0036] Reference Figure 6 , Figure 6 DD is a cross-sectional view of the deflocculation device of this embodiment. Figure 3 As shown, as a further optimization solution, in this embodiment, a limit rod 23 is vertically provided on the side where the two circular plates are away from each other, the limit rod 23 abuts against the circular plate, the spacing between the two limit rods 23 is smaller than the spacing between the two circular plates, and the limit rod 23 is fixedly connected to the shell 1.

[0037] In this embodiment, a limit rod 23 is arranged on the side where the two circular plates are away from each other. The limit rod 23 is used to ensure that the V-shape formed by the two circular plates remains stable when the two circular plates rotate, thereby further ensuring the effect of removing fiber lint on the yarn. In addition, by moving the limit rod 23, the angle between the two circular plates can be adjusted.

[0038] As a further optimization solution, in this embodiment, a spring is sleeved on the transmission shaft, and the spring is located between the two circular plates and abuts against them respectively.

[0039] In this embodiment, the spring can cooperate with the limiting rod 23 to further stabilize the V-shape formed by the two circular plates.

[0040] As a further optimization scheme, in this embodiment, a guide pulley 24 is coaxially sleeved on the transmission shaft, and the guide pulley 24 is rotatably connected with the transmission shaft around its circumference. The guide pulley 24 is located between two circular plates, and springs are respectively arranged between the two ends of the guide pulley 24 and the circular plates. One end of the spring abuts against the guide pulley 24, and the other end abuts against the circular plate.

[0041] In this embodiment, the guide pulley 24 is used to prevent the yarn from moving too much in the horizontal direction when the two rubbing plates 3 drive the yarn to rotate around the circumference, which would cause excessive friction between the yarn and the scraper 2 and lead to yarn breakage.

[0042] As a further optimization solution, in this embodiment, a plurality of pairs of circular plates are provided at equal intervals on the transmission shaft to clean fiber fluff from a plurality of yarns simultaneously.

[0043] In this embodiment, a plurality of pairs of circular plates are arranged on the transmission shaft, which can clean fiber fluff from a plurality of yarns at the same time, thus meeting the production requirements of the warp knitting machine.

[0044] Reference Figure 4 , Figure 4FIG. BB is a cross-sectional view of the lint-clearing device of this embodiment. Figure 4 As shown, as a further optimization solution, in this embodiment, the thickness of the edge of the circular plate gradually decreases along its radial direction to form a cutting edge on the outer side of the circular plate.

[0045] In this embodiment, a blade is provided on the edge of the circular plate, which can further enhance the cleaning effect of fiber fluff on the yarn.

[0046] The present invention proposes a driving mechanism of a warp knitting lint-clearing device comprising: a screw 5, a motor 6 and a gear set 7. The motor 6 is fixed on the housing 1. The two rubbing plates 3 are respectively provided with screws 5. The sliding directions of the screws 5 and the rubbing plates 3 are parallel to each other. The output shaft of the motor 6 is fixedly connected to one of the screws 5. The output shaft of the motor 6 and the other screw 5 are connected by the gear set 7. At the same time, scrapers 2 are arranged at both ends of the rubbing plates 3 near the through hole 11. Figure 7 , Figure 7 EE is a cross-sectional view of the deflocculation device of this embodiment, as shown in Figure 7 As shown, the scrapers 2 (circular plates) on both sides can use a pulley set 8 to replace the rotational power, so that the rubbing plate 3 drives the yarn to rotate around its circumference and the scraper 2 (circular plate) rotates synchronously, further improving the cleaning effect of the cleaning device on the fiber fluff on the yarn.

[0047] After the fiber fluff on the yarn is removed, the cleaning device of the present invention has two partitions 12 fixedly arranged on both sides of the housing 1 near the end of the screw 5 and tilted downward, and the removed fiber fluff falls into the bottom of the housing 1 between the two partitions 12 .

[0048] In order to further improve the cleaning effect of fiber fluff, a suction pipe 13 with a filter screen at the end is installed on one side of the bottom of the shell 1. The suction pipe 13 is connected to an external negative pressure device through a pipeline to actively suck the removed fiber fluff into the inner bottom of the shell 1.
