Description

Technical Field

[0001] The invention relates to the technical field of dyeing, in particular to a dyeing device and a dyeing method for rabbit hair blended fibers. Background Art

[0002] Rabbit hair blended fiber is a textile material made by mixing rabbit hair with other fiber materials. As a high-grade textile raw material, rabbit hair has excellent warmth retention and softness. With the development of the textile industry, rabbit hair blended fiber products are becoming more and more popular among the public and are widely used in clothing, home textiles and other fields. In the production process, rabbit hair blended fiber, like other blended fibers, also needs to be dyed to improve its appearance. When dyeing rabbit hair blended fibers, due to the relatively soft characteristics of rabbit hair, warp beam dyeing machines are mostly used. The warp beam dyeing machine structure consists of a core shaft, a dyeing vat, a reversing valve, a heat exchanger and a circulation pump. Before dyeing, the fabric is flatly wound on the core shaft to ensure that the surface of the fabric is in close contact with the small holes of the core shaft. The circulation pump introduces the dye solution into the dyeing vat and controls the flow direction of the dye solution inside and outside the core shaft through the reversing valve. The dye solution is sprayed out from the small holes of the core shaft and penetrates into the fabric to achieve uniform dyeing. Since the rabbit hair blended fibers are fixed on the warp beam rod when the warp beam dyeing machine is dyeing, the damage to the rabbit hair blended fibers can be minimized when dyeing the rabbit hair blended fibers. However, when the warp dyeing machine dyes rabbit hair blended fibers, the dye liquor needs to be heated, and the dye liquor is usually heated at the bottom of the machine body, which causes a large number of bubbles to be easily generated on the inner bottom wall of the machine body. After the bubbles are generated, they will float up with the dye liquor and pass through the rabbit hair blended fibers wrapped around the warp beam rod, which not only easily affects the dyeing efficiency, but also causes the dye liquor to be unable to evenly penetrate the fabric, resulting in uneven dyeing of the fabric and even spots. To this end, we propose a dyeing device and a dyeing method for rabbit hair blended fibers. Summary of the invention

[0008] Preferably, a scraper is threadedly connected to the reciprocating screw, the top of the scraper contacts the inner top wall of the shell, both sides of the scraper are fixedly connected to a limiting frame, and two collecting boxes are rotatably connected in the limiting frame.

[0009] Preferably, both ends of the limit frame are rotatably connected to the limit gears, and the limit gears are fixedly docked between the collection boxes on the same side thereof.

[0010] Preferably, a liquid collecting box is fixedly connected to one side of the shell away from the steam pipe, the bottom of the liquid collecting box is immersed in the dye liquid in the shell, and racks are fixedly connected to the tops of both sides of the liquid collecting box, and the racks can mesh with the bottom of the limiting gear on the same side.

[0011] Preferably, a sealing plate is rotatably connected to a side of the liquid collecting box close to the scraper, a torsion spring is provided at the connection between the sealing plate and the liquid collecting box, and a traction rope is fixedly connected to a side of the sealing plate close to the scraper.

[0012] Preferably, the scraper is rotatably connected to two winding rods on one side close to the liquid collecting box, and springs are provided at the connection between the two ends of the winding rods and the scraper, and the two winding rods are fixedly connected to one end of the traction rope on the same side thereof.

[0013] A dyeing method for a rabbit hair blended fiber dyeing device specifically comprises the following steps: S1: First, open the sealed door of the shell, pull out the load-bearing frame connected to the warp beam rod, then wind the rabbit wool blended fiber on the warp beam rod, push the load-bearing frame and the warp beam rod back into the shell, and close the sealed door of the shell; S2: After that, the dye liquid is transported into the shell through the liquid inlet pipe, and the dye liquid in the shell is heated by the heater. Then, the dye liquid in the shell is driven and guided by the commutator, and the circulation direction of the dye liquid in the shell is changed regularly. Through the commutator, the dye liquid can circulate forward and reverse during the dyeing process, so as to more effectively penetrate the fabric and ensure uniform dyeing; S3: During the dye liquid heating process, the dye liquid at the inner bottom wall of the shell will generate bubbles. The bubbles generated at this time will enter the guide frame A along the bottom of the mounting frame and move along the inner top wall of the guide frame A. When the bubbles move to the top of the guide frame A, they will enter the guide frame B and move in accordance with the inner top wall of the guide frame B. At this time, since the inner top wall of the guide frame B is provided with a cloth pad, the cloth pad will increase the friction between the bubbles and slow down the movement of the bubbles. At this time, the bubbles in the guide frame A will move quickly, while the bubbles in the guide frame B will move slowly. When the bubbles in the guide frame A enter the guide frame B, they will merge with the bubbles in the guide frame B to form relatively large bubbles. At this time, after the bubbles pass through the guide frame B, they will adhere to the inner top walls on both sides of the mounting frame and move toward the exhaust pipe. S4: When bubbles enter the exhaust pipe, they will first pass through the knife holder, which can break the bubbles. At this time, the gas in the bubbles will stay in the exhaust pipe. When the gas stored in the exhaust pipe is large, the air pressure inside the exhaust pipe will increase, and the air pressure will generate thrust on the sealing ball, pushing the sealing ball open. In this process, the sealing ball will squeeze and contract the spring. At this time, the installation tube A and the installation tube B are connected. At this time, the gas in the exhaust pipe will be discharged through the exhaust pipe. When the gas in the exhaust pipe becomes less, the air pressure in the exhaust pipe becomes smaller. At this time, the thrust of the air pressure on the sealing ball becomes smaller, and the spring begins to rebound, driving the sealing ball to move toward the installation tube A, so that it returns to its original position, thereby sealing the exhaust pipe; S5: When the dye solution is heated, steam will be generated. At this time, the steam will be discharged through the steam pipe 12. In the process of the steam passing through the steam pipe 12, it will pass through each guide plate and cooperate with the guide plate to drive the ring gear to rotate. In the process of the ring gear rotating, the ring gear will cooperate with the transmission gear to drive the reciprocating screw to rotate. In the process of the reciprocating screw rotating, the scraper will be driven to move back and forth along the reciprocating screw. At this time, the scraper can scrape off the water droplets condensed on the top wall of the shell and scrape the water droplets into the collection box of the limit frame. When the scraper moves When it reaches the top of the liquid collecting box, the limit gears on the limit frames on both sides of the scraper will mesh with the racks on the same side in turn, and the racks will drive the limit gears to rotate, and the limit gears will drive the collection box connected to it to rotate. When the collection box rotates, the condensed water collected in the collection box can be poured into the liquid collecting box and temporarily stored in the liquid collecting box. At this time, since the bottom of the liquid collecting box is immersed in the dye liquid in the shell, the temperature of the dye liquid in the shell heats the liquid in the liquid collecting box, so that the temperature of the liquid in the liquid collecting box and the dye liquid tend to be the same; S6: In the process of the scraper moving away from the liquid collecting box, the rack can drive the limit gear meshing with it to rotate in the opposite direction, so that the limit gear and the collecting box rotate back to their original positions, and in the process of the scraper moving, the traction rope is pulled and begins to be released from the winding rod. When the traction rope on the winding rod is completely released, the winding rod begins to pull the sealing plate through the traction rope to open the sealing plate. At this time, the liquid in the liquid collecting box can be discharged into the outer shell and mixed with the dye liquid inside it. When the scraper moves toward the liquid collecting box, the pulling force of the scraper on the traction rope disappears, and the springs at both ends of the winding rod begin to rebound, driving the winding rod to rotate in the opposite direction and winding the traction rope. Since the tension on the sealing plate disappears, the torsion springs on both sides of it begin to rebound, driving the sealing plate back to its original position, and continuing to seal the liquid collecting box. At this time, the subsequent condensed water can continue to be collected through the liquid collecting box.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adopts the design of the mounting frame. When bubbles are generated on the inner bottom wall of the shell, the bottom arc design of the mounting frame can be used to guide the bubbles, so that the bubbles float up along the guide frame A and the guide frame B. When the bubbles float up to the inner bottom walls on both sides of the mounting frame, they will enter the exhaust pipe. At this time, the bubbles are broken by the knife holder, and the gas in the bubbles is stored in the exhaust pipe. At this time, the air pressure in the exhaust pipe will increase, and thrust will be generated on the sealing ball to push the sealing ball open, so that the gas in the exhaust pipe is discharged, and the bubble elimination work is completed, so as to avoid the problem of excessive bubbles generated at the inner bottom wall of the shell, which affects the dyeing efficiency of rabbit hair blended fibers. At the same time, after the gas in the exhaust pipe is discharged, the spring starts to rebound, driving the sealing ball back to its original position, and continuing to seal the mounting pipe A, so as to prevent the problem of excessive heat loss in the shell; 2. The present invention uses an air cushion at the bottom of the mounting ring, which can make the mounting ring float above the liquid level in the exhaust pipe, and the mounting ring and the knife holder can follow the height of the liquid level in the exhaust pipe and float up and down synchronously, so that when the bubbles emerge from the liquid surface in the exhaust pipe, the knife holder can break the bubbles that emerge from the liquid surface in the exhaust pipe more quickly, thereby improving the bubble elimination efficiency of the device; 3. When the steam pipe of the present invention discharges the steam inside the shell, the flow of steam can drive the gear ring to rotate, and the gear ring and the transmission gear can be used to drive the reciprocating screw to rotate. At this time, the reciprocating screw drives the scraper to move back and forth. During the movement of the scraper, the condensed water attached to the top wall of the shell can be collected and dropped into the collecting box. When the scraper moves to the liquid collecting box, the limiting gear and the rack can cooperate to drive the collecting box to rotate, so that the condensed water in the collecting box is poured into the liquid collecting box. At this time, since the bottom of the liquid collecting box is immersed in the dye liquid in the shell, the condensed water in the liquid collecting box is heated by the dye liquid, so that the temperature of the condensed water and the dye liquid tend to be the same. When the scraper is away from the liquid collecting box, the sealing plate can be pulled open by the traction rope, so that the condensed water in the liquid collecting box is discharged into the shell, so as to avoid the condensed water on the top wall of the shell directly falling into the shell dye liquid, resulting in the temperature change of the dye liquid. At the same time, it can also avoid the problem of excessive loss caused by heating and evaporation of the dye liquid to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0018] See also Figure 1-11 The present invention provides a technical solution: a dyeing device and a dyeing method for rabbit wool blended fiber, comprising a shell 1, wherein the shell 1 is filled with dye liquid, a heater 13 is fixedly connected to the bottom of the shell 1, a commutator 14 is fixedly connected to one end of the shell 1, and the commutator 14 is mainly composed of machines such as a circulation pump. By starting the commutator 14, the dye liquid in the shell 1 can be driven and diverted, and the circulation direction of the dye liquid in the shell 1 can be changed regularly. A sealing door is provided at one end of the shell 1 away from the commutator 14, a liquid inlet pipe 11 is fixedly connected to the top of the shell 1, a steam pipe 12 is fixedly connected to the side of the shell 1 close to the commutator 14, and the steam pipe 12 is located above the commutator 14, a mounting frame 2 of a "U"-shaped structure is fixedly connected between the inner walls on both sides of the shell 1, two connecting ports 24 are provided on both sides of the mounting frame 2, a load-bearing frame 5 is slidably connected to the inner bottom wall of the mounting frame 2, and a warp shaft rod 51 is rotatably connected to the load-bearing frame 5.

[0019] Furthermore, during dyeing, the sealed door of the outer shell 1 is opened, the load-bearing frame 5 connected to the warp shaft rod 51 is pulled out, and then the rabbit hair blended fiber is wound on the warp shaft rod 51, and the load-bearing frame 5 and the warp shaft rod 51 are pushed back into the outer shell 1, and then the dye liquid is transported into the outer shell 1 through the liquid inlet pipe 11, and the heater 13 is used to heat the dye liquid in the outer shell 1, and then the commutator 14 is used to drive and guide the dye liquid in the outer shell 1, and now the rabbit hair blended fiber wound on the warp shaft rod 51 can be dyed.

[0020] Combined with Figure 3 , Figure 4 , Figure 5 and Fig. 9 As shown, both sides of the mounting frame 2 are fixedly connected with inclined guide frames A21, and both sides of the mounting frame 2 are also fixedly connected with guide frames B22 in the opposite inclination direction of the guide frames A21, and the guide frames B22 are both located above the guide frames A21 on the same side thereof, and a cloth pad 23 is arranged on the inner top wall of the guide frame B22, and the two connecting ports 24 are respectively located above the guide frames A21 and B22, and the spaces at the top and bottom of the mounting frame 2 can be connected through the connecting ports 24, and at the same time, because the connecting ports 24 are arranged above each guide frame A21 and guide frame B22, the bubbles can be prevented from contacting the guide frames A21 and B22 through the blocking effect of the guide frames A21 and B22. Regarding the problem of the rabbit hair blended fiber on the warp shaft rod 51, a number of exhaust pipes 3 are fixedly connected between the top of both sides of the mounting frame 2 and the inner wall of the shell 1 on the same side thereof, and the exhaust pipes 3 are respectively fixedly connected with mounting tubes A31 and mounting tubes B32, and the mounting tube A31 is located below the mounting tube B32, and a sealing ball 33 is placed on the top of the mounting tube A31, and a spring 34 is fixedly connected to the bottom of the mounting tube B32, and the bottom of the spring 34 is in contact with the top of the sealing ball 33, and a mounting ring 4 is slidably connected in the exhaust pipe 3, and the mounting ring 4 is located below the mounting tube A31, and a knife holder 41 is fixedly connected in the mounting ring 4, and an air cushion 42 is fixedly connected to the bottom of the mounting ring 4.

[0021] Furthermore, when the dye liquid at the inner bottom wall of the shell 1 generates bubbles due to heating, the bubbles generated at this time will enter the guide frame A21 along the bottom of the mounting frame 2 and move along the inner top wall of the guide frame A21. When the bubbles move to the top of the guide frame A21, they will enter the guide frame B22 and move along the inner top wall of the guide frame B22. At this time, since the inner top wall of the guide frame B22 is provided with a cloth pad 23, the cloth pad 23 will increase the friction between the bubbles and slow down the movement of the bubbles. At this time, the bubbles in the guide frame A21 will move quickly, while the bubbles in the guide frame B22 will move slowly. When the bubbles in the guide frame A21 enter the guide frame B22, the bubbles in the guide frame A22 will move slowly. After entering the rack B22, it will merge with the bubbles in the guide rack B22 to form relatively large bubbles. At this time, after passing through the guide rack B22, the bubbles will fit to the inner top walls on both sides of the mounting rack 2 and move toward the exhaust pipe 3. At this time, due to the design of the air cushion 42, the mounting ring 4 and the tool holder 41 can float up and down with the dye liquid level in the exhaust pipe 3, so that the distance between the tool holder 41 and the liquid level remains unchanged, thereby improving the bubble elimination efficiency of the tool holder 41. When the bubbles enter the exhaust pipe 3, they will first pass through the tool holder 41, and the bubbles can be broken by the tool holder 41. At this time, the gas in the bubbles will stay in the exhaust pipe 3. When the gas in the exhaust pipe 3 is stored more. The air pressure inside the exhaust pipe 3 increases, and the air pressure will generate a thrust on the sealing ball 33, pushing the sealing ball 33 open. In this process, the sealing ball 33 will squeeze and contract the spring 34. At this time, the mounting tube A31 and the mounting tube B32 are connected. At this time, the gas in the exhaust pipe 3 will be discharged through the exhaust pipe 3. When the gas in the exhaust pipe 3 becomes less, the air pressure in the exhaust pipe 3 becomes smaller. At this time, the thrust of the air pressure on the sealing ball 33 becomes smaller, and the spring 34 begins to rebound, driving the sealing ball 33 to move toward the mounting tube A31, so that it returns to its original position, thereby sealing the exhaust pipe 3.

[0022] Combined with Figure 6 , Figure 7 , Figure 8 , Fig.10 and Fig.11As shown, the inner wall of the shell 1 near the steam pipe 12 is rotatably connected to a reciprocating screw 6, and the end of the reciprocating screw 6 near the steam pipe 12 is fixedly connected to a transmission gear 61, and the end of the steam pipe 12 near the shell 1 is rotatably connected to a ring gear 62, and the ring gear 62 and the transmission gear 61 are meshed with each other, and a plurality of evenly distributed guide plates 63 are fixedly connected inside the ring gear 62, and a scraper 7 is threadedly connected to the reciprocating screw 6, and the top of the scraper 7 is in contact with the inner top wall of the shell 1, and both sides of the scraper 7 are fixedly connected to a limiting frame 71, and two collecting boxes 72 are rotatably connected to the limiting frame 71, and both ends of the limiting frame 71 are rotatably connected to limiting gears 73, and the limiting gears 73 are both connected to the collecting boxes 72 on the same side. The shell 1 is fixedly connected to the side of the steam pipe 12 with a liquid collecting box 8, the bottom of the liquid collecting box 8 is immersed in the dye liquid in the shell 1, and the tops of both sides of the liquid collecting box 8 are fixedly connected with racks 83, and the racks 83 can mesh with the bottom of the limit gear 73 on the same side thereof, and the liquid collecting box 8 is rotatably connected with a sealing plate 81 on the side close to the scraper 7, and a torsion spring is provided at the connection between the sealing plate 81 and the liquid collecting box 8, and a traction rope 82 is fixedly connected with the sealing plate 81 on the side close to the scraper 7, and two winding rods 74 are rotatably connected to the side of the scraper 7 close to the liquid collecting box 8, and springs are provided at the connection between the two ends of the winding rod 74 and the scraper 7, and the two winding rods 74 are fixedly connected to one end of the traction rope 82 on the same side thereof.

[0023] Furthermore, during dyeing, water vapor generated by the heating of the dye solution will be discharged through the steam pipe 12. In the process of the steam passing through the steam pipe 12, it will pass through the guide plate 63 and cooperate with the guide plate 63 to drive the ring gear 62 to rotate. In the process of the ring gear 62 rotating, the ring gear 62 will cooperate with the transmission gear 61 to drive the reciprocating screw 6 to rotate. In the process of the reciprocating screw 6 rotating, the scraper 7 will be driven to move back and forth along the reciprocating screw 6. At this time, the scraper 7 can scrape off the water droplets condensed on the top wall of the housing 1 and scrape the water droplets into the collection area of ​​the limit frame 71. When the scraper 7 moves to the top of the liquid collecting box 8, the limiting gears 73 on the limiting frames 71 on both sides of the scraper 7 will mesh with the racks 83 on the same side in turn, and the limiting gears 73 will be driven to rotate through the racks 83, and the limiting gears 73 will drive the collection box 72 connected thereto to rotate. When the collection box 72 rotates, the condensed water collected in the collection box 72 can be poured into the liquid collecting box 8 and temporarily stored in the liquid collecting box 8. At this time, since the bottom of the liquid collecting box 8 is immersed in the dye liquid in the shell 1, the liquid in the liquid collecting box 8 is heated by the temperature of the dye liquid in the shell 1. The body is heated to make the temperature of the condensed water in the liquid collecting box 8 close to the temperature of the dye liquid, and the influence of the condensed water on the temperature of the dye liquid is reduced as much as possible. When the scraper 7 moves away from the liquid collecting box 8, the rack 83 can drive the limit gear 73 meshed with it to rotate in the opposite direction, so that the limit gear 73 and the collecting box 72 rotate back to their original positions. In the process of the scraper 7 moving, the traction rope 82 is pulled and begins to be released from the winding rod 74. When the traction rope 82 on the winding rod 74 is completely released, the winding rod 74 begins to pull the sealing plate 81 through the traction rope 82, so that the sealing plate 81 is When the plate 81 is opened, the liquid in the liquid collecting box 8 can be discharged into the outer shell 1 and mixed with the dye liquid inside. When the scraper 7 moves toward the liquid collecting box 8, the pulling force of the scraper 7 on the traction rope 82 disappears, and the springs at both ends of the winding rod 74 begin to rebound, driving the winding rod 74 to rotate in the opposite direction and winding the traction rope 82. Since the tension on the sealing plate 81 disappears, the torsion springs on both sides thereof begin to rebound, driving the sealing plate 81 back to its original position, and continuing to seal the liquid collecting box 8. At this time, the subsequent condensed water can continue to be collected through the liquid collecting box 8.

[0024] A dyeing method for a rabbit hair blended fiber dyeing device specifically comprises the following steps: S1: First, open the sealing door of the housing 1, pull out the load-bearing frame 5 connected to the warp beam rod 51, then wind the rabbit wool blended fiber on the warp beam rod 51, push the load-bearing frame 5 and the warp beam rod 51 back into the housing 1, and close the sealing door of the housing 1; S2: Afterwards, the dye liquid is transported into the housing 1 through the liquid inlet pipe 11, and the dye liquid in the housing 1 is heated by the heater 13. Then, the dye liquid in the housing 1 is driven and guided by the commutator 14, and the circulation direction of the dye liquid in the housing 1 is changed regularly. Through the commutator 14, the dye liquid can be circulated forward and reversely during the dyeing process, so as to more effectively penetrate the fabric and ensure uniform dyeing; S3: During the dye liquid heating process, bubbles will be generated in the dye liquid at the inner bottom wall of the shell 1. The bubbles generated at this time will enter the guide frame A21 along the bottom of the mounting frame 2 and move along the inner top wall of the guide frame A21. When the bubbles move to the top of the guide frame A21, they will enter the guide frame B22 and move along the inner top wall of the guide frame B22. At this time, since the inner top wall of the guide frame B22 is provided with a cloth pad 23, the cloth pad 23 will increase the friction between the bubbles and slow down the movement of the bubbles. At this time, the bubbles in the guide frame A21 will move quickly, while the bubbles in the guide frame B22 will move slowly. When the bubbles in the guide frame A21 enter the guide frame B22, they will merge with the bubbles in the guide frame B22 to form relatively large bubbles. At this time, after passing through the guide frame B22, the bubbles will stick to the inner top walls on both sides of the mounting frame 2 and move toward the exhaust pipe 3. S4: When the bubbles enter the exhaust pipe 3, they will first pass through the knife holder 41, and the bubbles can be broken by the knife holder 41. At this time, the gas in the bubbles will stay in the exhaust pipe 3. When the gas stored in the exhaust pipe 3 is large, the air pressure inside the exhaust pipe 3 increases, and the air pressure will generate thrust on the sealing ball 33, pushing the sealing ball 33 open. In this process, the sealing ball 33 will squeeze and contract the spring 34. At this time, the installation tube A31 and the installation tube B32 are connected. At this time, the gas in the exhaust pipe 3 will be discharged through the exhaust pipe 3. When the gas in the exhaust pipe 3 decreases, the air pressure in the exhaust pipe 3 decreases. At this time, the thrust of the air pressure on the sealing ball 33 decreases, and the spring 34 begins to rebound, driving the sealing ball 33 to move toward the installation tube A31, so that it returns to its original position, thereby sealing the exhaust pipe 3; S5: When the dye solution is heated, steam is generated. At this time, the steam is discharged through the steam pipe 12. In the process of the steam passing through the steam pipe 12, it passes through each guide plate 63, and cooperates with the guide plate 63 to drive the ring gear 62 to rotate. In the process of the ring gear 62 rotating, the ring gear 62 cooperates with the transmission gear 61 to drive the reciprocating screw 6 to rotate. In the process of the reciprocating screw 6 rotating, the scraper 7 is driven to move back and forth along the reciprocating screw 6. At this time, the scraper 7 can scrape off the water droplets condensed on the top wall of the shell 1, and scrape the water droplets into the collection box 72 of the limit frame 71. When the scraper 7 moves to the collection box 72, the scraper 7 is moved to the collection box 72. When the liquid box 8 is above the liquid box 8, the limiting gears 73 on the limiting frames 71 on both sides of the scraper 7 will mesh with the racks 83 on the same side in turn, and the racks 83 will drive the limiting gears 73 to rotate, and the limiting gears 73 will drive the collection box 72 connected thereto to rotate. When the collection box 72 rotates, the condensed water collected in the collection box 72 can be poured into the liquid collection box 8 and temporarily stored in the liquid collection box 8. At this time, since the bottom of the liquid collection box 8 is immersed in the dye liquid in the shell 1, the temperature of the dye liquid in the shell 1 heats the liquid in the liquid collection box 8, so that the temperature of the liquid in the liquid collection box 8 and the dye liquid tend to be the same; S6: When the scraper 7 moves away from the liquid collecting box 8, the rack 83 can drive the limit gear 73 meshed with it to rotate in the opposite direction, so that the limit gear 73 and the collecting box 72 rotate back to their original positions. In the process of the scraper 7 moving, the traction rope 82 is pulled and begins to be released from the winding rod 74. When the traction rope 82 on the winding rod 74 is completely released, the winding rod 74 begins to pull the sealing plate 81 through the traction rope 82 to open the sealing plate 81. At this time, the liquid in the liquid collecting box 8 can be discharged to The shell 1 is inside and mixed with the dye liquid inside it. When the scraper 7 moves toward the liquid collecting box 8, the pulling force of the scraper 7 on the traction rope 82 disappears, and the springs at both ends of the winding rod 74 begin to rebound, driving the winding rod 74 to rotate in the opposite direction and winding the traction rope 82. Since the tension on the sealing plate 81 disappears, the torsion springs on both sides thereof begin to rebound, driving the sealing plate 81 back to its original position and continuing to seal the liquid collecting box 8. At this time, the subsequent condensed water can continue to be collected through the liquid collecting box 8.

[0025] Working principle: first, the housing 1 is installed at the designated position and powered on, then the sealed door is opened, the load-bearing frame 5 connected to the warp shaft rod 51 is pulled out, then the rabbit hair blended fiber is wound on the warp shaft rod 51, and the load-bearing frame 5 and the warp shaft rod 51 are pushed back into the housing 1, then the dye liquid is transported into the housing 1 through the liquid inlet pipe 11, and the heater 13 is used to heat the dye liquid in the housing 1, and then the commutator 14 is used to drive and guide the dye liquid in the housing 1, and now the rabbit hair blended fiber wound on the warp shaft rod 51 can be dyed; When the dye liquid at the inner bottom wall of the shell 1 generates bubbles due to heating, the bubbles generated at this time will enter the guide frame A21 along the bottom of the mounting frame 2 and move along the inner top wall of the guide frame A21. When the bubbles move to the top of the guide frame A21, they will enter the guide frame B22 and move along the inner top wall of the guide frame B22. At this time, since the inner top wall of the guide frame B22 is provided with a cloth pad 23, the cloth pad 23 will increase the friction between the bubbles and slow down the movement of the bubbles. At this time, the bubbles in the guide frame A21 will move quickly, while the bubbles in the guide frame B22 will move slowly. When the bubbles in the guide frame A21 enter the guide frame B22, the bubbles in the guide frame A22 will move slowly. After entering the exhaust pipe 3, it will merge with the bubbles in the guide frame B22 to form relatively large bubbles. At this time, after the bubbles pass through the guide frame B22, they will fit to the inner top walls on both sides of the mounting frame 2 and move toward the exhaust pipe 3. At this time, due to the design of the air cushion 42, the mounting ring 4 and the tool holder 41 can float up and down with the dye liquid level in the exhaust pipe 3, so that the distance between the tool holder 41 and the liquid level remains unchanged, thereby improving the bubble elimination efficiency of the tool holder 41. When the bubbles enter the exhaust pipe 3, they will first pass through the tool holder 41, and the bubbles can be broken by the tool holder 41. At this time, the gas in the bubbles will stay in the exhaust pipe 3. When the gas in the exhaust pipe 3 is stored more. The air pressure inside the exhaust pipe 3 increases, and the air pressure will generate a thrust on the sealing ball 33, pushing the sealing ball 33 open. In this process, the sealing ball 33 will squeeze and shrink the spring 34. At this time, the mounting pipe A31 and the mounting pipe B32 are connected. At this time, the gas in the exhaust pipe 3 will be discharged through the exhaust pipe 3. When the gas in the exhaust pipe 3 decreases, the air pressure in the exhaust pipe 3 decreases. At this time, the thrust of the air pressure on the sealing ball 33 decreases, and the spring 34 starts to rebound, driving the sealing ball 33 to move toward the mounting pipe A31, so that it returns to its original position and continues to block the mounting pipe A31, thereby avoiding the problem of excessive loss of dye temperature in the housing 1. At the same time, when dyeing is performed, water vapor generated by the heating of the dye solution will be discharged through the steam pipe 12. In the process of the steam passing through the steam pipe 12, it will pass through the guide plate 63, and cooperate with the guide plate 63 to drive the ring gear 62 to rotate. In the process of the ring gear 62 rotating, the ring gear 62 will cooperate with the transmission gear 61 to drive the reciprocating screw 6 to rotate. In the process of the reciprocating screw 6 rotating, the scraper 7 will be driven to move back and forth along the reciprocating screw 6. At this time, the scraper 7 can scrape off the water droplets condensed on the top wall of the shell 1 and scrape the water droplets into the collection box of the limit frame 71. 72, when the scraper 7 moves to the top of the liquid collecting box 8, the limiting gears 73 on the limiting frames 71 on both sides of the scraper 7 will mesh with the racks 83 on the same side in turn, and the racks 83 will drive the limiting gears 73 to rotate, and the limiting gears 73 will drive the collection box 72 connected thereto to rotate. When the collection box 72 rotates, the condensed water collected in the collection box 72 can be poured into the liquid collecting box 8 and temporarily stored in the liquid collecting box 8. At this time, since the bottom of the liquid collecting box 8 is immersed in the dye liquid in the shell 1, the temperature of the dye liquid in the shell 1 will affect the liquid in the liquid collecting box 8. The condensed water in the liquid collecting box 8 is heated to be close to the temperature of the dye liquid, and the influence of the condensed water on the temperature of the dye liquid is reduced as much as possible. When the scraper 7 moves away from the liquid collecting box 8, the rack 83 can drive the limit gear 73 meshed with it to rotate in the opposite direction, so that the limit gear 73 and the collecting box 72 are rotated back to their original positions. In the process of the scraper 7 moving, the traction rope 82 is pulled and begins to be released from the winding rod 74. When the traction rope 82 on the winding rod 74 is completely released, the winding rod 74 begins to pull the sealing plate 81 through the traction rope 82, so that the sealing plate 81 is opened, and the liquid in the liquid collecting box 8 can be discharged into the shell 1 and mixed with the dye liquid inside it. When the scraper 7 moves toward the liquid collecting box 8, the pulling force of the scraper 7 on the traction rope 82 disappears, and the springs at both ends of the winding rod 74 begin to rebound, driving the winding rod 74 to rotate in the opposite direction and winding the traction rope 82. Since the tension on the sealing plate 81 disappears, the torsion springs on both sides thereof begin to rebound, driving the sealing plate 81 back to its original position, and continuing to seal the liquid collecting box 8. At this time, the subsequent condensed water can continue to be collected through the liquid collecting box 8.

A dyeing method for a dyeing device for rabbit hair blended fibers, characterized in that: The dyeing method of the dyeing device for rabbit hair blended fibers according to claim 9 specifically comprises the following steps: S1: First, open the sealed door of the housing (1), pull out the load-bearing frame (5) connected to the warp shaft rod (51), then wind the rabbit wool blended fiber around the warp shaft rod (51), push the load-bearing frame (5) and the warp shaft rod (51) back into the housing (1), and close the sealed door of the housing (1); S2: Then, the dye liquid is transported into the housing (1) through the liquid inlet pipe (11), and the dye liquid in the housing (1) is heated by the heater (13). Then, the dye liquid in the housing (1) is driven and guided by the commutator (14), and the circulation direction of the dye liquid in the housing (1) is changed at regular intervals. Through the commutator (14), the dye liquid can circulate forward and reverse during the dyeing process, thereby more effectively penetrating the fabric and ensuring uniform dyeing. S3: During the dyeing process, the dyeing liquid at the inner bottom wall of the housing (1) will generate bubbles. The bubbles will enter the guide frame A (21) along the bottom of the mounting frame (2) and move along the inner top wall of the guide frame A (21). When the bubbles move to the top of the guide frame A (21), they will enter the guide frame B (22) and move along the inner top wall of the guide frame B (22). At this time, since the inner top wall of the guide frame B (22) is provided with a cloth pad (23), the cloth pad (23) 3) The friction between the guide frame A (21) and the bubbles will increase, causing the bubbles to move more slowly. At this time, the bubbles in the guide frame A (21) will move quickly, while the bubbles in the guide frame B (22) will move slowly. When the bubbles in the guide frame A (21) enter the guide frame B (22), they will merge with the bubbles in the guide frame B (22) to form relatively large bubbles. At this time, after the bubbles pass through the guide frame B (22), they will adhere to the inner top walls on both sides of the mounting frame (2) and move toward the exhaust pipe (3); S4: When bubbles enter the exhaust pipe (3), they will first pass through the knife holder (41), and the bubbles can be broken by the knife holder (41). At this time, the gas in the bubbles will stay in the exhaust pipe (3). When the gas stored in the exhaust pipe (3) is large, the air pressure inside the exhaust pipe (3) increases, and the air pressure will generate thrust on the sealing ball (33), pushing the sealing ball (33) open. In this process, the sealing ball (33) will squeeze and shrink the spring (34). At this time, the installation tube A (31) and the installation tube B (32) are connected. At this time, the gas in the exhaust pipe (3) will be discharged through the exhaust pipe (3). When the gas in the exhaust pipe (3) decreases, the air pressure in the exhaust pipe (3) decreases. At this time, the thrust of the air pressure on the sealing ball (33) decreases, and the spring (34) begins to rebound, driving the sealing ball (33) to move toward the installation tube A (31) and return it to its original position, thereby sealing the exhaust pipe (3); S5: When the dye liquid is heated, steam is generated. At this time, the steam is discharged through the steam pipe 12. In the process of the steam passing through the steam pipe 12, the steam passes through each guide plate (63) and cooperates with the guide plate (63) to drive the ring gear (62) to rotate. In the process of the ring gear (62) rotating, the ring gear (62) cooperates with the transmission gear (61) to drive the reciprocating screw (6) to rotate. In the process of the reciprocating screw (6) rotating, the scraper (7) is driven to move back and forth along the reciprocating screw (6). At this time, the scraper (7) can scrape off the water droplets condensed on the top wall of the housing (1) and scrape the water droplets into the collection box (72) of the limit frame (71). When the scraper (7) moves to the liquid collecting box ( 8), the limiting gears (73) on the limiting frames (71) on both sides of the scraper (7) will mesh with the racks (83) on the same side in turn, and the racks (83) will drive the limiting gears (73) to rotate, and the limiting gears (73) will drive the collection box (72) connected thereto to rotate. When the collection box (72) rotates, the condensed water collected in the collection box (72) can be poured into the liquid collection box (8) and temporarily stored in the liquid collection box (8). At this time, since the bottom of the liquid collection box (8) is immersed in the dye liquid in the shell (1), the temperature of the dye liquid in the shell (1) is used to heat the liquid in the liquid collection box (8), so that the temperature of the liquid in the liquid collection box (8) and the temperature of the dye liquid tend to be the same; S6: When the scraper (7) moves away from the liquid collecting box (8), the rack (83) can drive the limit gear (73) meshed with it to rotate in the opposite direction, so that the limit gear (73) and the collecting box (72) rotate back to their original positions. In addition, when the scraper (7) moves, the traction rope (82) is pulled and begins to be released from the winding rod (74). When the traction rope (82) on the winding rod (74) is completely released, the winding rod (74) begins to pull the sealing plate (81) through the traction rope (82), so that the sealing plate (81) is opened. At this time, the liquid in the liquid collecting box (8) is The liquid can be discharged into the housing (1) and mixed with the dye liquid inside the housing (1). When the scraper (7) moves toward the liquid collecting box (8), the pulling force of the scraper (7) on the traction rope (82) disappears, and the springs at both ends of the winding rod (74) start to rebound, driving the winding rod (74) to rotate in the opposite direction and winding the traction rope (82). Since the pulling force on the sealing plate (81) disappears, the torsion springs on both sides of the sealing plate (81) start to rebound, driving the sealing plate (81) back to its original position, and continuing to seal the liquid collecting box (8). At this time, the subsequent condensed water can continue to be collected through the liquid collecting box (8).
