Description

Technical Field

[0001] This invention relates to the field of dyeing and processing technology, specifically to a dyeing equipment and dyeing process for brewing protein fiber blended yarn. Background Technology

[0002] Brewing protein fiber is not only biodegradable, but also a new technology that promotes the circular economy. When blended with cashmere and wool into yarns, fabrics, and clothing, it will reflect the high-end and luxurious nature of cashmere, as well as its green, non-toxic, and biodegradable characteristics, and may even "replace" cashmere.

[0003] In the process of blending protein fibers for brewing, oil and wax are applied to the surface of the yarn during spinning to avoid friction affecting its quality. Therefore, it is necessary to remove the oil and wax from the yarn surface to improve its capillary effect and penetration. Existing dyeing equipment sends the yarn to be dyed into a yarn vat for bleaching or washing. After dyeing, the grey yarn is sent to a dewatering machine for dehydration and then dried. However, multiple yarns are usually sent into the yarn vat for washing, and multiple partitions are used to separate the yarns. This requires a large yarn vat for washing, which is costly. If the distance between the yarns is reduced, the yarns may become tangled, making it difficult to ensure normal yarn output. Summary of the Invention

[0014] A dyeing process for a dyeing device for brewing protein fiber blended yarn, applicable to the aforementioned dyeing device for brewing protein fiber blended yarn, comprising the following steps: S1: During the yarn feeding stage, multiple yarns are loaded into the guide grooves of two pressure rollers to separate the yarns. Two drive motors are started, and the drive motors drive the two pressure rollers to rotate through the corresponding drive rods to feed the multiple yarns. S2: During the yarn setting stage, the drive rod drives the turntable to rotate via the first transmission belt, causing the push rod to drive the push plate to move back and forth. The pressure rod on the mounting plate intermittently presses the yarn to prevent multiple yarns from getting tangled during the washing process. S3: During the yarn shaking stage, the pressure rod drives the transmission gear on the positioning rod to contact the rack plate, causing the transmission gear to rotate. The pressure rod uses the strip groove on its surface to make the yarn shake, improving the yarn cleaning efficiency. Then, the cleaned yarn is conveyed out and enters the dyeing vat for dyeing. S4: During the cleaning stage, the drive rod drives the prism rod to rotate via the second transmission belt.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses a pressing mechanism to enable two pressing rollers to separate and transport multiple yarns through a guide groove, which facilitates the feeding of yarns into the yarn cylinder and intermittently presses the outer side of the yarns to prevent yarn tangling and ensure that multiple yarns are cleaned simultaneously, thereby achieving the effect of safe yarn cleaning.

[0016] 2. The present invention uses a shaking mechanism that allows the yarn to rotate while the pressure bar presses it. The pressure bar, in conjunction with the strip groove on its outer side, shakes the yarn, which facilitates the rapid dispersal of wax blocks on the yarn surface, thereby improving the cleaning efficiency of the yarn.

[0017] 3. The present invention, through its cleaning mechanism, enables multiple roller brushes to rotate synchronously and move horizontally back and forth during the yarn conveying process of the pressure roller. This facilitates the cleaning of residual oil stains and wax blocks in the wire groove by the roller brushes, preventing the pressure roller from slipping during yarn conveying, thereby improving the stability of yarn conveying and the convenience of cleaning the pressure roller.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8The diagram illustrates a dyeing device for brewing protein fiber blended yarn, comprising a yarn cylinder 1 and two symmetrically rotating pressure rollers 2 mounted inside the yarn cylinder 1. The yarn cylinder 1 is installed at the pretreatment end of the dyeing vat to clean oil stains and wax blocks from the yarn surface, facilitating subsequent dyeing. Multiple equally spaced guide grooves are provided on the outer side of the pressure rollers 2 to separate multiple yarns and prevent tangling. A drive rod 3 is fixedly mounted inside the pressure rollers 2, with both ends of the drive rod 3 rotatably mounted inside the yarn cylinder 1. Two symmetrically distributed mounting boxes 4 are fixedly mounted on the outer side of the yarn cylinder 1. A drive motor 5 is mounted at one end of the drive rod 3 and is fixedly mounted on the outer side of the adjacent mounting box 4. The output end of the drive motor 5 is fixedly connected to one end of the drive rod 3, allowing the two drive motors 5 to drive the pressure rollers 2 to rotate via the corresponding drive rods 3. The guide grooves on the two pressure rollers 2 position and convey multiple yarns, feeding them into the yarn cylinder 1 for cleaning, facilitating their entry into the next stage for drying and dyeing.

[0022] The pressing mechanism includes two push plates 6 symmetrically arranged inside the yarn cylinder 1. The two push plates 6 can synchronously position multiple yarns. The pressing mechanism also includes a mounting box 9 fixedly installed on the outside of the mounting box 4. Two transmission rods 10 are rotatably installed on both sides of the yarn cylinder 1, respectively located inside the two mounting boxes 9. A first transmission belt 11 is rotatably installed between the transmission rods 10 and the adjacent drive rods 3. A positioning seat 12 is fixedly installed inside the mounting box 9. A turntable 13 is rotatably installed outside the positioning seat 12. The outer side of the turntable 13 and the outer side of the transmission rods 10 are both fixedly installed with corresponding... The meshing bevel gears 14 cause the drive rod 3 to rotate, which in turn drives the transmission rod 10 to rotate via the first transmission belt 11. The transmission rod 10 drives the turntable 13 to rotate via the two bevel gears 14. A connecting rod 15 is hinged to the side of the turntable 13 away from the bevel gears 14, and the hinge point between the connecting rod 15 and the turntable 13 is away from the center of the turntable 13, so that the turntable 13 can drive the connecting rod 15 to perform circular motion. A push rod 16 is hinged to the end of the connecting rod 15 away from the turntable 13. The push rod 16 slides to the inside of the yarn cylinder 1, and the two push rods 16 are respectively fixed to the two push plates 6. The connection allows the turntable 13 to drive the connecting rod 15 in a circular motion, which in turn pushes the push rod 16 to move reciprocally along the inner side of the yarn cylinder 1. The push rod 16 then drives the push plate 6 to move synchronously, and the two push plates 6 move in opposite directions. Multiple mounting plates 17 are fixedly installed at the bottom of the push plate 6 in an equidistant manner, and multiple pressure rods 18 are installed at the top of the mounting plates 17 in an equidistant manner. The number of pressure rods 18 corresponds to the number of wire grooves. The mounting plates 17 at the bottom of the two push plates 6 are staggered, so that when the push plate 6 moves, it can drive multiple pressure rods 18 through the mounting plates 17. 8 contacts the outer side of the yarn and intermittently presses and positions the yarn to ensure that each yarn is separated from the others and avoids tangling. Two symmetrically distributed guide rods 32 are slidably installed on the inner side of the mounting plate 17, and the guide rods 32 are fixedly installed on the inner side of the yarn cylinder 1. When the push plate 6 pushes the mounting plate 17 to move, the mounting plate 17 can move along the outer side of the guide rods 32, improving the stability of the movement of the mounting plate 17. The end of the pressure rod 18 away from the mounting plate 17 has a spherical structure to prevent the yarn from detaching from the pressure rod 18 when it pushes the yarn.

[0023] Example 2: Please refer to Figures 3-7This embodiment further illustrates Example 1. The shaking mechanism shown in the figure includes a base plate 7 fixedly installed at the bottom of the inner wall of the yarn cylinder 1. The base plate 7 can shake and remove wax blocks on the yarn surface. The shaking mechanism also includes multiple positioning frames 19 fixedly installed at equal intervals on the top of the base plate 7. The number of positioning frames 19 is the same as the number of mounting plates 17, and the bottom of the mounting plate 17 contacts the top of the positioning frames 19. A positioning rod 20 is fixedly installed at the bottom of the push rod 16, and the positioning rod 20 passes through the mounting plate 17 and extends to the inner side of the positioning frame 19. A transmission gear 21 is fixedly installed at the end of the positioning rod 20 away from the push rod 16. Multiple rack plates 22 are fixedly installed at equal intervals on the inner side of the positioning frame 19, and the rack plates 22 mesh with adjacent transmission gears 21, so that when the mounting plate 17 moves, it can drive the positioning rod 20 at the bottom of the push rod 16 to move synchronously. The positioning rod 20 drives the transmission gear 21 to move synchronously. The inner side of the positioning frame 19 moves, causing the rack plate 22 to drive the transmission gear 21 to rotate. The transmission gear 21 drives the push rod 16 to rotate through the positioning rod 20. The outer side of the push rod 16 has multiple centrally symmetrically distributed strip grooves, so that when the push rod 16 comes into contact with the yarn, the multiple strip grooves can work together with the outer side of the push rod 16 to continuously move the yarn. Two symmetrically distributed scrapers 33 are fixedly installed on the outer side of the mounting plate 17, and the outer side of the scrapers 33 is in contact with the outer side of the positioning frame 19. When the mounting plate 17 moves, the scrapers 33 can scrape off the wax residue on the outer side of the positioning frame 19, avoiding the formation of lumps, and also improving the sealing between the mounting plate 17 and the positioning frame 19. A limit ring 34 is fixedly installed on the outer side of the positioning rod 20. The top of the limit ring 34 is in contact with the bottom of the mounting plate 17, so that the limit ring 34 provides support for the positioning rod 20 and improves the smoothness of the rotation of the positioning rod 20.

[0024] Example 3: Please refer to Figures 1-8This embodiment further illustrates other embodiments. The cleaning mechanism shown in the figure includes a roller brush 8 disposed above the wire groove, which can clean the wire groove. The cleaning mechanism also includes a rotating drum 23 disposed above the pressure roller 2. The roller brush 8 is fixedly installed on the outside of the rotating drum 23, so that when the rotating drum 23 rotates, it can drive the roller brush 8 to clean the oil stains and wax blocks in the wire groove. A prismatic rod 24 is slidably installed on the inner side of the rotating drum 23. The two ends of the prismatic rod 24 extend to the inner sides of the two mounting boxes 4 respectively, and a second transmission belt 25 is rotatably installed between the prismatic rod 24 and the adjacent drive rod 3, so that... When the drive rod 3 rotates, it can drive the prismatic rod 24 to rotate via the second transmission belt 25. The prismatic rod 24 drives the rotating drum 23 to rotate, which in turn drives the roller brush 8 to rotate. A mounting plate 26 is fixedly installed at one end of the rotating drum 23. A first sliding groove is provided on the outer side of the yarn cylinder 1 for the mounting plate 26 to slide in a limited manner. A baffle 27 is fixedly installed on the side of the yarn cylinder 1 near the mounting plate 26. Multiple centrally symmetrically distributed sliding balls 28 are fixedly installed on the side of the mounting plate 26 near the baffle 27. An arc-shaped groove is provided on the side of the baffle 27 near the mounting plate 26 for the sliding balls 28 to slide in a limited manner, and the depth of the arc-shaped groove is three times the outer diameter of the sliding ball 28. One-third of the rotating drum 23 has an mounting ring 29 rotatably mounted on the end away from the mounting plate 26. A groove is provided on the outer side of the yarn cylinder 1 for the mounting ring 29 to slide within a limited position. A fixing cylinder 30 is fixedly mounted on the side of the yarn cylinder 1 away from the baffle 27. A spring 31 is fixedly mounted on the outer side of the mounting ring 29, abutting against the inner side of the fixing cylinder 30. When the rotating drum 23 rotates, it drives the mounting plate 26 and the mounting ring 29 to rotate synchronously. The mounting plate 26 drives the sliding ball 28 to rotate, causing the sliding ball 28 to move out of the arc-shaped groove of the baffle 27. Using the reaction force of the baffle 27 on the sliding ball 28, the sliding ball 28 pushes the rotating drum 23 along the prismatic rod via the mounting plate 26. As the outer side of 24 moves, the rotating drum 23 compresses the spring 31 through the mounting ring 29. As the rotating drum 23 rotates, the slider 28 aligns with the arc groove again. Using the rebound force of the spring 31, the slider 28 enters the arc groove. Thus, the rotating drum 23 can move horizontally along the outer side of the prism rod 24. The roller brush 8 can then clean the oil stains on the inner side of the wire groove. A stop bar 35 is provided above the rotating drum 23. The outer side of the roller brush 8 contacts the outer side of the stop bar 35. The stop bar 35 is fixedly installed on the inner side of the yarn cylinder 1 so that when the roller brush 8 rotates, it can contact the stop bar 35, which is convenient for cleaning the wax block on the surface of the roller brush 8.

[0025] Working principle: First, the operator loads multiple yarns into the guide grooves of the two pressing rollers 2 and starts the two drive motors 5. The drive motors 5 drive the corresponding drive rods 3 to rotate, which in turn drives the pressing rollers 2 to rotate. The two pressing rollers 2 then transport the separated yarns, immersing them into the yarn cylinder 1. Simultaneously, the drive rods 3 drive the transmission rods 10 to rotate via the first transmission belt 11. The transmission rods 10 drive the turntable 13 to rotate via two bevel gears 14, causing the turntable 13 to drive the connecting rod 15 to move in a circular motion. The connecting rod 15 pushes the push rod 16 to move reciprocally along the inner side of the yarn cylinder 1. The push rod 16 drives the push plate 6 to move synchronously. The push rod 16 drives multiple mounting plates 17 to move synchronously along the top of the positioning frame 19, causing the mounting plates 17 to drive multiple pressure rods 18 to contact the outer side of the yarn. Since the two push plates 6 move in opposite directions, the mounting plates 17 on the two push plates 6 can synchronously approach the yarn, achieving centered positioning of the yarn. At the same time, the pressure rod 18 drives the transmission gear 21 on the positioning rod 20 to move along the outer side of the rack plate 22, causing the rack plate 22 to drive the transmission gear 21 to rotate. The transmission gear 21 drives the pressure rod 18 to rotate. The pressure rod 18, in conjunction with the strip groove on its outer side, makes the yarn vibrate, improving the cleaning efficiency of the yarn cylinder 1. The drive rod 3 drives the prismatic rod 24 to rotate via the second transmission belt 25, which in turn drives the rotating drum 23 to rotate. The rotating drum 23 drives multiple roller brushes 8 to rotate within the wire groove of the pressure roller 2. Simultaneously, the rotating drum 23 drives the mounting plate 26 to rotate, which in turn drives multiple sliding balls 28 to move synchronously. This causes the sliding balls 28 to move out of the arc-shaped groove of the baffle plate 27. The reaction force of the baffle plate 27 on the sliding balls 28 pushes the mounting plate 26 to move. The mounting plate 26 then pushes the rotating drum 23 to move along the outer side of the prismatic rod 24. The rotating drum 23 compresses the spring 31 via the mounting ring 29, and as the rotating drum 23 continues to rotate, the sliding balls 28... The roller 23 will align with the arc groove again, and the spring 31 will push the mounting ring 29 to move the rotating drum 23 along the outside of the prism rod 24. The ball 28 on the mounting plate 26 can then enter the arc groove. Thus, the rotating drum 23 can move horizontally along the outside of the prism rod 24. During the rotation, the roller brush 8 can move horizontally back and forth, so that the roller brush 8 can quickly clean the oil stains and wax blocks in the wire groove. Finally, the pressure roller 2 conveys the cleaned yarn out and into the dyeing vat for dyeing, thereby achieving the effect of quickly cleaning the yarn, avoiding the situation of multiple yarns getting tangled, and facilitating the continuous cleaning of multiple yarns.

10. A dyeing apparatus for brewing protein fiber blended yarn based on any one of claims 1 to 9 further includes a dyeing process, characterized in that: The dyeing process includes the following steps: S1: During the yarn feeding stage, multiple yarns are loaded into the wire grooves of two pressure rollers (2) to separate the multiple yarns. Two drive motors (5) are started so that the drive motors (5) drive the two pressure rollers (2) to rotate through the corresponding drive rods (3) to feed the multiple yarns. S2: During the setting stage, the drive rod (3) drives the turntable (13) to rotate through the first transmission belt (11), causing the push rod (16) to drive the push plate (6) to move back and forth. The pressure rod (18) on the mounting plate (17) intermittently presses the yarn to prevent multiple yarns from getting tangled during the washing process. S3: During the shaking stage, the pressure rod (18) drives the transmission gear (21) on the positioning rod (20) to contact the rack plate (22), causing the transmission gear (21) to rotate. The pressure rod (18) uses the strip groove on its surface to make the yarn shake, improving the yarn cleaning efficiency. Then, the cleaned yarn is conveyed out and enters the dyeing vat for dyeing. S4: During the cleaning stage, the drive rod (3) drives the prism rod (24) to rotate through the second transmission belt (25), and then the rotating drum (23) moves horizontally back and forth in the process of the ball (28) and the arc groove on the baffle (27) driving the roller brush (8) to clean the oil stains and wax blocks in the wire groove.
