Description

Technical Field

[0001] The invention relates to the technical field of colored yarn dyeing and cleaning, and in particular to a cleaning device and method for colored yarn immersion dyeing. Background Art

[0002] As a unique yarn category in the textile field, the manufacturing process of colored yarn is different from traditional spinning. It first dyes the fiber into colored fiber, and then fully mixes two or more fibers of different colors, and then spins them into yarn with a unique mixed color effect. In the processing of colored yarn, printing and dyeing plays a key role. However, there is a problem that cannot be ignored in this process, that is, during the printing and dyeing process, a large amount of dye chemical raw materials will remain on the colored yarn. The composition of these residual substances is complex, including various chemical additives and unreacted dyes. Therefore, the development of an efficient and reliable cleaning device for colored yarn immersion dyeing is of vital importance to ensuring the quality of colored yarn products and the health of consumers.

[0003] The cleaning fluid of the cleaning agent is injected into the cleaning tank, and the cleaning fluid is passed through the gap between the upper pressing wheel and the lower pressing wheel of the yarn feeding drive mechanism at one end of the cleaning agent, and then passed through the gap between the bottom pressing wheel opening at the bottom of the cleaning agent near one end of the yarn feeding drive mechanism and the cleaning tank, and then passed through the gap between the upper pressing wheel and the lower pressing wheel on the yarn discharging drive mechanism, and then passed through the cleaning fluid in the cleaning tank.

[0004] In the above-mentioned prior art, after the colored yarn is cleaned, some cleaning liquid may still remain on the colored yarn, which not only increases the burden of the subsequent drying process and prolongs the drying time, but also may have potential effects on the colored yarn due to the chemicals in the residual cleaning liquid.

[0005] Therefore, a cleaning device and method for immersion dyeing of colored yarns are needed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art. The present invention proposes a cleaning device and method for immersion dyeing of colored yarn to solve the problem in the above-mentioned prior art that some cleaning liquid may still remain on the colored yarn after the colored yarn is cleaned.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a cleaning device and method for soaking and dyeing colored yarn, including a cleaning device, a protective shell is rotatably installed on the upper end of the cleaning device, the cleaning device includes a cleaning box, a conveying device is fixedly installed on one end of the cleaning box, an extrusion device is fixedly installed on the middle section of the interior of the cleaning box, a water suction device is fixedly installed on the other end of the cleaning box, two groups of limiting rollers are arranged inside the cleaning box, an air blowing knocking device is arranged between one group of limiting rollers and the water suction device, the air blowing knocking device is fixedly connected to the cleaning box, the air blowing knocking device includes an air blowing outer shell, multiple groups of fans are fixedly installed on the upper end of the air blowing outer shell, multiple groups of exhaust ports are provided on the inner side of the air blowing outer shell, the exhaust ports are symmetrically arranged at the upper and lower ends of the inner side of the air blowing outer shell, and the air blowing outer shell is fixedly connected to the cleaning box. One side of the shell is an expansion port, and the other side of the air-blowing shell is a contraction port. One side of one group of fans is provided with a drive motor 1, and an eccentric wheel is fixedly installed on the driving end of the drive motor 1. The end of the eccentric wheel away from the drive motor 1 is rotatably connected to the fan, and an opening and closing component is slidingly provided on the lower end of the eccentric wheel. A vibration component is fixedly installed on one side of the multiple groups of fans, and the vibration component is connected to the multiple groups of fans. When the colored yarn needs to be cleaned, the colored yarn is manually passed through the conveying device, the limiting roller, the extrusion device, the other group of limiting rollers, and the air-blowing knocking device in turn, and then removed through the water absorption device. A winding device is provided at one end of the cleaning device close to the water absorption device to wind up the colored yarn, and cleaning liquid is added to the cleaning box. When the colored yarn passes through the cleaning device, the winding is started Device and conveying device, the colored yarn is first flattened and conveyed by the conveying device, and is limited by a set of limit rollers through the conveying device to prevent the colored yarn from deviating during the conveying process. The preliminary cleaning of the colored yarn begins in the process of the conveying device passing through the limit rollers. At this time, the position where the colored yarn is initially cleaned after passing through the cleaning box is squeezed and dehydrated by the extrusion device. The colored yarn squeezed by the extrusion device passes through the cleaning box through another set of limit rollers for cleaning. In order to prevent the colored yarn from being transported from another set of limit rollers to the air-blowing and knocking device, when passing through the cleaning liquid level inside the cleaning box, impurities may adhere to the surface of the colored yarn, resulting in reduced efficiency of subsequent cleaning and drying, the driving motor is started to drive multiple sets of fans to start operation, and when driving When the motor rotates, it drives the eccentric wheel to rotate. When the eccentric wheel rotates, the upper end continuously squeezes the opening and closing components inside the air blowing shell, so that the opening and closing components continuously open and close the lower outlet of the fan. When the lower outlet of the fan is opened, the wind blows the sticky substances on the upper and lower surfaces of the colored yarn through the exhaust port of the air blowing shell, and at the same time blows away some floating substances on the surface of the cleaning liquid inside the cleaning box, so that they are away from the liquid surface of the colored yarn. At the same time, since the material of the colored yarn is relatively light, the viscosity of moisture and adsorbents is not strong. When the colored yarn is blown by air, a short air blow can fully blow out the impurities and moisture on the surface of the liquid surface section of the upper end of the colored yarn. Continuous air blowing will cause a waste of resources. At the same time, continuous air blowing, especially when the air flow speed is high,The fibers on the surface of the colored yarn will be subjected to greater impact and friction. Over a long period of time, this may lead to increased hairiness on the fiber surface. At the same time, the continuous action of the airflow may change the shape of the colored yarn, which may cause distortion and deformation. When the lower end outlet of the fan is closed, the wind vibrates the colored yarn through the vibration component, removing impurities remaining in the gaps on the surface of the colored yarn, further improving the cleaning efficiency of the colored yarn and reducing the complexity of subsequent operations.

[0008] The transmission mechanism of the present invention is a pair of transmission mechanisms, and the transmission mechanism of the present invention is a pair of transmission mechanisms, and the transmission mechanism of the transmission mechanism is a pair of transmission mechanisms.

[0009] Furthermore, a rotating column is rotatably installed at one end of the conveying roller away from the connecting column, and two groups of threaded columns are fixedly installed on the inner side of the U-shaped connecting plate. The rotating column is threadedly connected to the threaded column. When the two groups of conveying rollers need to be replaced, the conveying rollers can be taken out and replaced by rotating the rotating column away from the threaded column.

[0010] The cam is fixedly mounted on the top of the U-shaped connecting plate, and the cam is fixedly mounted on the bottom of the U-shaped connecting plate, and the cam is fixedly mounted on the top of the U-shaped connecting plate, and the cam is fixedly mounted on the bottom of the U-shaped connecting plate. The preliminary cleaning begins when the conveying device passes through the limiting roller. At this time, the colored yarn passing through the cleaning box is squeezed and dehydrated at the position where it is initially cleaned. The distance between the squeezing roller one and the squeezing roller two is adjusted by rotating the rotating rod one, and the squeezing force of the colored yarn is adjusted. By squeezing the colored yarn after the preliminary cleaning, most of the soluble impurities on the surface of the colored yarn have been removed after the preliminary cleaning, but some impurities and cleaning liquid still remain in the fiber gaps. The extrusion process can effectively compress the colored yarn and squeeze out these residual substances, so that when the colored yarn is washed for the second time, the cleaning liquid can penetrate into the fiber more quickly and deeply, thereby increasing the cleaning effect of the colored yarn.

[0011] Furthermore, one set of limiting rollers is located between the conveying device and the extrusion device, and the other set of limiting rollers is located between the extrusion device and the air blowing and knocking device. The two sets of limiting rollers are used to limit the colored yarn during the transportation and cleaning process to prevent the colored yarn from shifting during transportation, which would cause a decrease in the cleaning effect of the colored yarn.

[0012] Furthermore, two sets of drainage grooves are provided at the lower end of the inner part of the air-blowing shell, through which a small amount of water that falls into the inner part of the air-blowing shell during the colored yarn cleaning is discharged, thereby preventing the water from affecting the exhaust air at the exhaust port of the air-blowing shell.

[0013] When the eccentric wheel is rotated, the L-shaped connecting rod inside the air blowing housing is continuously squeezed, so that the L-shaped connecting rod drives the opening and closing plate to slide in the sliding housing, and the opening and closing plate is pushed out and pulled back by the elastic member inside the sliding housing, so as to realize intermittent opening and closing of the lower end outlet of the fan.

[0014] Furthermore, the vibration component includes multiple groups of connecting pipes, one end of each group of connecting pipes is connected to the discharge port at the lower end of the fan, and the other end of the connecting pipe is fixedly installed with a connecting shell 1, and multiple groups of elastic parts 2 are fixedly installed inside the connecting shell 1. The elastic coefficients of the multiple groups of elastic parts 2 are different, and the lower ends of the multiple groups of elastic parts 2 are fixedly installed with knocking columns, and the upper ends of the multiple groups of knocking columns are slidingly connected to the connecting pipes. When the lower end outlet of the fan is closed, wind flows into the connecting shell 1 through the multiple groups of connecting pipes, squeezing the knocking columns inside the connecting shell 1. Since the elastic coefficients of the multiple groups of elastic parts 2 are different, the knocking columns knock on the colored yarn alternately. By vibrating the colored yarn, the impurities remaining in the gaps on the surface of the colored yarn are vibrated and removed, thereby further improving the cleaning efficiency of the colored yarn.

[0015] The outer end of the driving member is fixedly provided with a driving member which is cooperatively connected with the driving member, and the driving member is rotated by the driving member, and the driving member is rotated by the driving member. Second, when bypassing the connecting column 2 in the middle section and the connecting column 2 in the lower section, the colored yarn is wound around the connecting column 2 in an S shape, and the moisture inside the colored yarn is fully absorbed by the water-absorbing sponge on each connecting column 2. By starting the driving motor 3, the connecting column 2 in the middle section is driven to rotate, and the friction contact between each connecting column 2 is increased, thereby improving the water absorption efficiency. By rotating the rotating rod 2, the distance between the upper and lower connecting columns 2 and the middle connecting column 2 can be adjusted, and then the water absorption efficiency of the water-absorbing sponge can be improved by changing the contact area between the colored yarn and the connecting column 2. At the same time, when adjusting the distance between the upper connecting column 2 and the middle connecting column 2, the angle between the colored yarn and the air blowing shell is indirectly adjusted, and the contact distance between the knocking column and the colored yarn can be changed to improve the vibration effect of the knocking column and the colored yarn. When the distance between the upper connecting column 2 and the middle connecting column 2 is increased, the distance between the colored yarn and the knocking column becomes shorter, further improving the knocking effect, and at the same time, the inclination angle between the colored yarn and the air blowing shell is increased, thereby improving the air blowing efficiency, and further improving the cleaning effect of the colored yarn.

[0016] Further, the following steps are included: S1: Check the integrity of each component of the cleaning device to ensure that the conveying device, extrusion device, air blowing and knocking device and water absorption device are firmly installed; adjust the conveying device, set two sets of appropriate conveying rollers, adapt them to the width of the colored yarn, and then tighten the threaded column; adjust the extrusion device, turn the rotating rod 1 to drive the screw rod, so that the sliding block 1 drives the extrusion roller 1 to move up and down, set the distance between the extrusion roller 1 and the extrusion roller 2, and adjust the distance between the extrusion roller 2 and the extrusion roller 1 to 0.5mm-3mm through the screw rod, and control the pressure range to 0.1MPa-0.5MPa; Adjust the water absorption device, rotate the rotating rod 2 to drive the bidirectional screw, adjust the position of the sliding block 2, change the distance between the upper and lower connecting columns 2 and the middle connecting column 2, adjust the winding angle of the colored yarn to 30°-60° through the bidirectional screw, and match the compression rate of the water-absorbing sponge to 20%-40%, to achieve a dehydration effect with a moisture content of ≤15%; S2: The colored yarn passes through the conveying roller of the conveying device, the squeezing rollers 2 and 1 of the squeezing device, and the exhaust area of ​​the air blowing shell in sequence, and is wound in an S shape on the water-absorbing sponge of the connecting column 2 in the water absorption device. Then, the two ends of the colored yarn are fixed to the inlet end of the conveying device and the winding device respectively, and the winding speed is adjusted according to the density of the colored yarn; S3: Open the protective shell and inject cleaning liquid into the cleaning box until the dyed yarn soaking section is submerged. The liquid level is controlled by the overflow port. S4: Start the drive motor 2 and the winding device, drive gear 1 and gear 2 to drive the conveying roller to convey the colored yarn at a speed ratio of 1:1, so that it completes the initial soaking in the cleaning box, and mechanically dehydrates the colored yarn after the initial cleaning through the extrusion device to squeeze out the residual liquid in the fiber gap, start the drive motor 1 to drive the eccentric wheel to rotate, and drive the opening and closing plate to reciprocate in the sliding shell through the L-shaped connecting rod to achieve intermittent opening and closing of the lower end outlet of the fan; through the action of the eccentric wheel, the fan is turned on for 30%-50% of the time, realizing the periodic alternation of blowing and knocking. When the fan is turned on, the high-speed airflow is blown on the surface of the colored yarn through the exhaust port in a pulsed manner; when the fan is turned off, the airflow drives the elastic part 2 through the connecting pipe to drive the knocking column to knock the colored yarn alternately; then start the drive motor 3 to drive the middle connecting column 2 to rotate, and at the same time adjust the contact pressure between the colored yarn and the water-absorbing sponge through the bidirectional screw to achieve dynamic water absorption.

[0017] Compared with the prior art, the beneficial effects of the present invention include: when the colored yarn needs to be cleaned, the colored yarn is manually passed through the conveying device, then through the limiting roller, then through the squeezing device, then through another set of limiting rollers, then through the air blowing and knocking device, and finally moved out through the water absorbing device; a winding device is provided at one end of the cleaning device close to the water absorbing device to wind up the colored yarn, and cleaning liquid is added to the cleaning box; after the colored yarn passes through the cleaning device, the winding device and the conveying device are started, and the colored yarn is first flattened and conveyed by the conveying device, and is limited by a set of limiting rollers through the conveying device to prevent The colored yarn is deviated during the conveying process, and the preliminary cleaning begins when the colored yarn passes through the limiting roller from the conveying device. At this time, the colored yarn is squeezed and dehydrated at the position where it is initially cleaned in the cleaning box by the squeezing device. The colored yarn squeezed by the squeezing device passes through another set of limiting rollers and is cleaned in the cleaning box. In order to prevent the colored yarn from being transported from another set of limiting rollers to the air-blowing knocking device and passing through the cleaning liquid level in the cleaning box, which may cause impurities to adhere to the surface of the colored yarn, resulting in a decrease in the efficiency of subsequent cleaning and drying, the driving motor is started to drive multiple sets of fans to start operation. At the same time, the eccentric wheel is driven to rotate. When the eccentric wheel rotates, the upper end continuously squeezes the opening and closing components inside the air blowing shell, so that the opening and closing components continuously open and close the lower outlet of the fan. When the lower outlet of the fan is opened, the wind blows through the exhaust port of the air blowing shell to wash the sticky substances on the upper and lower surfaces of the colored yarn, and at the same time blows away some floating substances on the surface of the cleaning liquid inside the cleaning box, so that they are away from the liquid surface of the colored yarn. At the same time, since the material of the colored yarn is relatively light, the viscosity of moisture and adsorbents is not strong. When the colored yarn is blown by air, a short air blow can remove impurities and The moisture is fully blown out. Continuous air blowing will cause a waste of resources. At the same time, continuous air blowing, especially when the air flow speed is high, will cause the fibers on the surface of the colored yarn to be subjected to greater impact and friction. Under long-term action, it may cause the hairiness on the fiber surface to increase. At the same time, the continuous action of the air flow may change the shape of the colored yarn, and may cause distortion and deformation. When the lower end outlet of the fan is closed, the wind vibrates the colored yarn through the vibration component, and the impurities remaining in the gaps on the surface of the colored yarn are vibrated and removed, further improving the cleaning efficiency of the colored yarn and reducing the complexity of subsequent operations.

Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0021] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

One side of one group of fans 152 is provided with a driving motor 153, and the driving end of the driving motor 153 is fixedly installed with an eccentric wheel 154. The end of the eccentric wheel 154 away from the driving motor 153 is rotatably connected to the fan 152, and the lower end of the eccentric wheel 154 is slidingly provided with an opening and closing component 155. One side of the multiple groups of fans 152 is fixedly installed with a vibration component 156, and the vibration component 156 is connected to the multiple groups of fans 152. When the colored yarn needs to be cleaned, the colored yarn is manually passed through the conveying device 12, The colored yarn is firstly flattened and conveyed by the conveying device 12 after passing through the conveying device 12, and is limited by a group of limiting rollers 14 through the conveying device 12 to prevent the colored yarn from shifting during the conveying process. The colored yarn begins to be initially cleaned in the process of the colored yarn passing through the limiting rollers 14 from the conveying device 12. At this time, the position where the colored yarn is initially cleaned after passing through the cleaning box 11 is squeezed and dehydrated by the squeezing device 13. The colored yarn squeezed by the squeezing device 13 passes through another set of limiting rollers 14 and is cleaned through the cleaning box 11. In order to prevent the colored yarn from being transported from the other set of limiting rollers 14 to the air blowing knocking device 15 and passing through the cleaning liquid level inside the cleaning box 11, which may cause impurities to adhere to the surface of the colored yarn, resulting in reduced efficiency of subsequent cleaning and drying, the driving motor 153 is started to drive the multiple sets of fans 152 to start operation. When the driving motor 153 rotates, the eccentric wheel 154 is driven to rotate.

At the same time, since the material of the colored yarn is relatively light, the viscosity of moisture and adsorbents is not strong. When the colored yarn is blown, a short air blow can fully blow out the impurities and moisture on the surface of the liquid surface section of the upper end of the colored yarn. Continuous air blowing will cause a waste of resources. At the same time, continuous air blowing, especially when the air flow speed is high, will cause the fibers on the surface of the colored yarn to be subjected to greater impact and friction. Under long-term action, it may cause the hairiness on the fiber surface to increase. At the same time, the continuous action of the air flow may change the shape of the colored yarn, and may cause distortion and deformation. When the lower end outlet of the fan 152 is closed, the wind vibrates the colored yarn through the vibration component 156, and removes the impurities remaining in the gaps on the surface of the colored yarn by vibration, further improving the cleaning efficiency of the colored yarn and reducing the complexity of subsequent operations.

When the colored yarn passes through the cleaning device 1, the winding device and the driving motor 2 125 are started, and the driving motor 2 125 drives the gear 1 1252 to rotate, and then drives the gear 2 1253 to rotate, and the two sets of conveying rollers 123 are driven by the gear 1252 and the gear 2 1253 to move relative to each other, so as to convey the colored yarn.

The two groups of limiting rollers 14 are used to limit the colored yarn during transportation and cleaning to prevent the colored yarn from shifting during transportation, which would cause a decrease in the cleaning effect of the colored yarn.

[0027] According to one embodiment of the present invention, Figure 1As shown, two sets of drainage grooves 1514 are opened at the lower end of the interior of the air blowing shell 151, through which a small amount of water that falls into the interior of the air blowing shell 151 when the colored yarn is cleaned is discharged, preventing the water from affecting the exhaust at the exhaust port 1511 of the air blowing shell 151.

[0028] According to one embodiment of the present invention, Figure 1 As shown, the opening and closing assembly 155 includes an L-shaped connecting rod 1551, the upper end of the L-shaped connecting rod 1551 is in contact with the eccentric wheel 154, the lower end of the L-shaped connecting rod 1551 is fixedly installed with an opening and closing plate 1552, the L-shaped connecting rod 1551 is slidably connected to the air blowing shell 151, one end of the opening and closing plate 1552 is slidably provided with a sliding shell 1553, the sliding shell 1553 is fixedly connected to one side of the air blowing shell 151, and the interior of the sliding shell 1553 is fixedly installed with multiple groups of elastic members 1554, and the multiple groups of elastic members 1554 are fixedly connected to the opening and closing plate 1552. When the L-shaped connecting rod 1551 is toggled, it drives The opening and closing plate 1552 squeezes multiple sets of elastic parts 1554 in the sliding housing 1553 to open and close the exhaust port of the fan 152, and drives the eccentric wheel 154 to rotate while the driving motor 153 rotates. When the eccentric wheel 154 rotates, it continuously squeezes the L-shaped connecting rod 1551 inside the air blowing housing 151, so that the L-shaped connecting rod 1551 drives the opening and closing plate 1552 to slide in the sliding housing 1553, and the opening and closing plate 1552 is pushed out and then pulled back by the elastic part 1554 inside the sliding housing 1553, thereby realizing intermittent opening and closing of the lower end outlet of the fan 152.

[0029] According to one embodiment of the present invention, Figure 1 As shown, the vibration assembly 156 includes multiple groups of connecting pipes 1561, one end of each of the multiple groups of connecting pipes 1561 is connected to the exhaust port at the lower end of the fan 152, the other end of the connecting pipe 1561 is fixedly installed with a connecting shell 1562, and multiple groups of elastic members 1563 are fixedly installed inside the connecting shell 1562. The elastic coefficients of the multiple groups of elastic members 1563 are different, and the lower ends of the multiple groups of elastic members 1563 are fixedly installed with knocking columns 1564, and the upper ends of the multiple groups of knocking columns 1564 are connected to the connecting shell 1562. The connecting pipe 1561 is slidably connected. When the lower end outlet of the fan 152 is closed, the wind flows into the connecting shell 1562 through the multiple groups of connecting pipes 1561, squeezing the knocking columns 1564 inside the connecting shell 1562. Since the elastic coefficients of the multiple groups of elastic parts 1563 are different, the knocking columns 1564 knock on the colored yarn alternately. By vibrating the colored yarn, the impurities remaining in the gaps on the surface of the colored yarn are vibrated and removed, thereby further improving the cleaning efficiency of the colored yarn.

[0030] According to one embodiment of the present invention, Figure 1As shown, the water absorption device 16 includes a connecting shell 2 161, the lower end of the connecting shell 2 161 is fixedly connected to the cleaning box 11, the internal rotation of the connecting shell 2 161 is rotatably installed with a two-way screw rod 1611, the upper end of the two-way screw rod 1611 is fixedly installed with a rotating rod 2 1613, the upper and lower ends of the two-way screw rod 1611 are threadedly installed with a sliding block 2 1612, the outer side of the sliding block 2 1612 is fixedly installed with a connecting column 2 166, the outer side of the connecting column 2 166 is pasted with a water-absorbing sponge 1661 through a universal sticker, another group of connecting columns 2 166 is provided between the two groups of connecting columns 2 166, and the two groups of connecting columns 2 166 are away from one side of the two-way screw rod 1611. The ends are fixedly installed with sliding blocks 3 1662, the interior of sliding blocks 3 1662 is slidingly provided with connecting columns 3 1621, the outer side of connecting columns 3 1621 is fixedly installed with connecting shell 3 162, the middle connecting column 2 166 is located near the end of connecting shell 3 162 and is fixedly installed with connecting column 4 165, the other end of connecting column 2 166 is rotatably connected to connecting shell 2 161, connecting column 4 165 passes through the interior of connecting shell 3 162, the outer side of connecting shell 3 162 is fixedly installed with connecting block 164, the upper end of connecting block 164 is fixedly installed with driving motor 3 163, and the driving end of driving motor 3 163 is fixedly connected to connecting column 4 165. The colored yarn passes through the air-blowing shell 151, bypasses the uppermost connecting post 2 166, bypasses the middle connecting post 2 166, and bypasses the lower connecting post 2 166, so that the colored yarn is wound around the connecting post 2 166 in an S shape, and the water inside the colored yarn is fully absorbed by the water-absorbing sponge 1661 on each connecting post 2 166. By starting the driving motor 3 163, the middle connecting post 2 166 is driven to rotate, thereby increasing the friction contact between each connecting post 2 166 and improving the water absorption efficiency. By rotating the rotating rod 2 1613, the distance between the upper and lower connecting posts 2 166 and the middle connecting post 2 166 can be adjusted, and then the distance between the colored yarn and the connecting post 2 166 is changed. The contact area of ​​the connecting column 2 166 is used to improve the water absorption efficiency of the absorbent sponge 1661. At the same time, when adjusting the distance between the upper connecting column 2 166 and the middle connecting column 2 166, the angle between the colored yarn and the air blowing shell 151 is indirectly adjusted. At the same time, the contact distance between the knocking column 1564 and the colored yarn can be changed to improve the vibration effect of the knocking column 1564 and the colored yarn. When the distance between the upper connecting column 2 166 and the middle connecting column 2 166 is increased, the distance between the colored yarn and the knocking column 1564 becomes shorter, which further improves the knocking effect. At the same time, the inclination angle between the colored yarn and the air blowing shell 151 is increased, which improves the air blowing efficiency and further improves the cleaning effect on the colored yarn.
