Description

Technical Field

[0001] This utility model relates to the field of cashmere low-temperature dyeing technology, specifically a cashmere low-temperature dyeing device. Background Technology

[0002] Conventional cashmere dyeing typically employs a boiling dyeing method, which, under the influence of high temperatures and chemical auxiliaries, severely damages the fibers, reducing cashmere fiber strength and hand feel. Low-temperature cashmere dyeing helps minimize fiber damage, bringing out the elegant natural style of cashmere products and improving the quality of dyed goods.

[0003] During the low-temperature dyeing process, appropriate auxiliaries need to be added to the dyeing vat at different times. However, due to the presence of cashmere in the dyeing vat, the mixing efficiency of the auxiliaries and the dye liquor is slow, resulting in a longer dyeing time and affecting the dyeing efficiency.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-3As shown, a cashmere low-temperature dyeing device includes a base 1, a dyeing vat 2 that can be electrically heated is mounted on the base 1, a side baffle 3 is mounted on the base 1, a top cover 4 is mounted on the side baffle 3, and a material cylinder 5. The surface of the material cylinder 5 is evenly perforated, and a stirring blade 6 is mounted at the bottom of the material cylinder 5. A movable plate 7 is mounted inside the side baffle 3. Two fixed rods 8 and a lead screw 9 are mounted between the side baffle 3 and the top cover 4. The movable plate 7 is slidably connected to the fixed rods 8, and a slider 10 that is threadedly connected to the lead screw 9 is mounted on the movable plate 7. A first motor 11 for driving the lead screw 9 to rotate is mounted on the top cover 4. A second motor 12 is installed on the 7. The output end of the second motor 12 passes through the movable plate 7. A U-shaped frame 13 is installed at the output end of the second motor 12. The two ends of the frame 13 are rotatably connected to the material cylinder 5. Extension rods 14 are installed on both sides of the material cylinder 5. Hand-tightening bolts 15 are threadedly connected to the extension rods 14. Threaded holes that cooperate with the hand-tightening bolts 15 are opened on the frame 13. Several feeding units are installed on the top cover 4. The feeding unit includes a material bottle 16. An end cap 17 is installed at the upper end of the material bottle 16. A pump body 18 is installed at the upper end of the end cap 17. The pump body 18 is connected to the dyeing vat 2 through a pipe 19.

[0018] Bottle 16 contains different solutions, including pH adjustment solution, dyeing agent, leveling agent, ethyl acetate solution, etc. The solutions can be delivered to dyeing vat 2 through pump body 18 and pipe 19. One end of pipe 19 located inside dyeing vat 2 is set on the inner wall of dyeing vat 2. At the same time, a one-way valve is set at this end of pipe 19 to prevent a large amount of solution in dyeing vat 2 from entering pipe 19.

[0019] When dyeing cashmere at low temperature, the cashmere material is first placed into the dyeing cylinder 5. A mesh cover with perforations can be installed at the upper end of the cylinder 5. The mesh cover can be connected to the cylinder 5 by snap-fit ​​or threaded connection to confine the cashmere within the cylinder 5. Then, the first motor 11 is started, driving the lead screw 9 to rotate. The lead screw 9 is threadedly connected to the slider 10 and slidably connected to the fixed rod 8 via the movable plate 7, allowing the movable plate 7 to move downwards. As the movable plate 7 moves downwards, it drives the frame 13 and the cylinder 5 below it to move downwards, causing the cylinder 5 to enter the dyeing vat 2 and ensuring that the cashmere in the cylinder 5 is completely immersed in the dye solution within the dyeing vat 2. Then, the dyeing vat 2 is slowly heated. The dyeing vat 2 is heated electromagnetically, so that the dye liquor in the dyeing vat 2 gradually rises from room temperature to 70° to 80°, at a rate of 1.5° per minute. When the predetermined temperature is reached, it is kept at that temperature for 30 minutes. During this process, the second motor 12 can be started, which drives the frame 13 and the material cylinder 5 below the frame 13 to rotate, so that the cashmere in the material cylinder 5 rotates. At the same time, the first motor 11 can be controlled to rotate in both forward and reverse directions, so that the cashmere in the material cylinder 5 can move up and down in the dyeing vat 2. By controlling the rotation and up and down movement of the cashmere, the cashmere and dye can be fully combined, so as to improve the dyeing efficiency and dyeing effect.

[0020] When it is necessary to add liquid solution to the dyeing vat 2, the first motor 11 can drive the material cylinder 5 to move upward, and then the pump body 18 can add a specific and quantitative solution to the dyeing vat 2. Then the second motor 12 is started, and the second motor 12 drives the frame 13 and the material cylinder 5 to rotate. The stirring blade 6 below the material cylinder 5 will also rotate synchronously. Since the cashmere is not in the dyeing vat 2, the rotation of the stirring blade 6 can quickly achieve uniform mixing of the dye liquor and the specific solution. After the mixing is completed, the first motor 11 can make the material cylinder 5 and the cashmere in the material cylinder 5 re-enter the dyeing vat 2.

[0021] When it is necessary to remove the cashmere from the cylinder 5, the first motor 11 moves the lower end of the cylinder 5 above the dyeing vat 2. Then, by turning the hand-tightening bolt 15, the hand-tightening bolt 15 is separated from the frame 13. At this time, the hand-tightening bolt 15 is still threadedly connected to the extension rod 14 on the outside of the cylinder 5. The hand-tightening bolt 15 and the cylinder 5 form a whole through the extension rod 14. The cylinder 5 can be flipped by the two hand-tightening bolts 15 so that the opening of the cylinder 5 faces the user. Then, the worker takes out the cashmere from the cylinder 5. After taking out the cashmere, the cylinder 5 is flipped by the two hand-tightening bolts 15 so that the extension rod 14 moves to one side of the frame 13. Then, the hand-tightening bolt 15 is connected to the frame 13 for subsequent use.

[0022] After the second motor 12 stops driving the frame 13 and the cylinder 5 to rotate, if the stopping position of the cylinder 5 and the frame 13 is not ideal, the frame 13 and the cylinder 5 can be manually controlled to rotate so that the cylinder 5 and the frame 13 can face the user in a suitable posture, so that the user can control the cylinder 5 to flip on the frame 13 and take away the cashmere inside the cylinder 5.

[0023] Furthermore, a cover plate 20 is provided on one side of the movable plate 7. The cover plate 20 and the movable plate 7 are connected by a hinge 21. When the dyeing in the dyeing vat 2 is heated, the cover plate 20 and the movable plate 7 can block the upper opening of the dyeing vat 2 to a certain extent, which can reduce heat loss. At the same time, the cover plate 20 can be flipped over to the top of the movable plate 7 to avoid the cover plate 20 affecting the user's operation.

[0024] Furthermore, an arc-shaped reinforcing plate 22 is provided on the upper surface of the movable plate 7 to improve the stability of the movable plate 7 when it moves up and down.

[0025] Furthermore, the top cover 4 has an clearance groove at its upper end, and a protective ring 23 is provided on the upper surface of the clearance groove to prevent the second motor 12 on the movable plate 7 from colliding with the end cover 17 when the movable plate 7 moves upward. The protective ring 23 can protect the second motor 12 that rises to this point, and at the same time provide stability to the top cover 4.

[0026] Furthermore, the surface of the stirring blade 6 is provided with through holes to facilitate better mixing of the newly added solution with the dyeing solution in the dyeing vat 2.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
