Description

Technical Field

[0001] This invention relates to the field of textile printing and dyeing equipment technology, and in particular to a dyeing vat for dyeing fabrics. Background Technology

[0002] Dyeing is the core process of giving fabric color in textile processing. As the main equipment in the dyeing process, the dyeing vat's structural design directly determines the contact efficiency between the dye liquor and the fabric, the uniformity of the temperature field distribution, and the energy consumption level of the dyeing process. Dyeing vats widely used in intermittent dyeing production mainly include ambient temperature and pressure dyeing machines (such as liquid flow dyeing machines and jet dyeing machines) and high temperature and high pressure dyeing machines (such as package dyeing machines and warp beam dyeing machines).

[0003] The aforementioned equipment has been used in the textile industry for a long time, but in actual operation, the following technical defects directly related to the mechanical structure design of the dyeing vat have been exposed: The existing dye liquor circulation in dyeing vats is usually driven by a centrifugal pump, entering from the bottom or side wall of the vat through the main circulation pipe, passing through the fabric stacking area, and returning from the top. However, due to the complex shape of the vat's internal cavity (such as the presence of baffles, heating pipes, fabric hangers, and other internal components), the dye liquor is prone to flow deviation, short circuits, or eddies when flowing within the vat. This results in differences in dye liquor concentration and temperature in different areas of the fabric, forming dyeing defects such as "color spots" and "color differences." Especially in the four corners of the dyeing vat, the back of the heating pipes, and areas with dense fabric stacking, the dye liquor has poor flowability, becoming dyeing dead zones. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a dyeing vat for fabric dyeing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dyeing vat for fabric dyeing, comprising a receiving frame, a dyeing vat body fixedly fitted inside the receiving frame, two control panels provided on the surface of the receiving frame, a heating module fixedly fitted on the outer wall of the dyeing vat body, four adjusting annular tubes movably fitted on the outer wall of the dyeing vat body, a plurality of adjusting nozzles fixedly connected to the inner wall of the adjusting annular tubes, the ends of the adjusting nozzles penetrating through the dyeing vat body and extending into the interior of the dyeing vat body, a material extraction component connected to the back of the dyeing vat body, and a fixing component connected to the surface of the dyeing vat body; Both sides of the outer wall of the dyeing vat body are fixedly connected to feeding channels, and the surface of the feeding channels is connected to moving components.

[0008] The moving component includes two self-locking motors fixedly connected to the surface of the feeding channel. The output end of each self-locking motor is fixedly connected to a moving roller.

Multiple installation nozzles are fixedly connected to the bottom of the installation tube. One end of the installation tube passes through the mounting recess and the drive housing and is rotatably connected to the installation telescopic tube. The electric telescopic rods are used to push and pull the mounting recess to move.

[0011] The end of the installation telescopic tube penetrates through the dyeing vat body and extends to the outside of the dyeing vat body.

[0018] A fixing component is connected to the surface of the dyeing vat body 2. The fixing component includes a fixed self-locking motor 26 fixedly connected to the surface of the dyeing vat body 2. A fixed roller 27 is fixedly connected to the output end of the fixed self-locking motor 26. Two fixing plates 28 are fixedly sleeved on the outer wall of the fixed roller 27. A transmission roller 29 is rotatably connected between the two fixing plates 28. The fixed roller 27 is driven to rotate by removing the fixed self-locking motor 26.

[0019] Both sides of the outer wall of the dyeing vat body 2 are fixedly connected to the feeding channel 11. The surface of the feeding channel 11 is connected to the moving component. The moving component includes two moving self-locking motors 12 fixedly connected to the surface of the feeding channel 11.

The end of the moving roller 13 passes through the feeding channel 11 and is rotatably connected to the inner wall of the feeding channel 11. The moving component achieves the purpose of speeding up the transmission of the fabric.

[0020] The dyeing vat body 2 has two symmetrical compensation components inside. Each compensation component includes two movable guide rods 14 fixedly connected between the two sides of the inner wall of the dyeing vat body 2. A movable plate 15 is movably sleeved between the two movable guide rods 14. A movable self-locking motor 16 is fixedly connected to the side wall of the dyeing vat body 2. A movable screw 17 is fixedly connected to the output end of the movable self-locking motor 16. The end of the movable screw 17 passes through the dyeing vat body 2 and is rotatably connected to the inner wall of the dyeing vat body 2. The outer side wall of the movable screw 17 is threadedly connected to the movable plate 15. Two electric telescopic rods 18 are fixedly connected to the bottom of the movable plate 15. A mounting recess 19 is fixedly connected between the piston ends of the two electric telescopic rods 18. A drive mechanism is fixedly connected to the surface of the mounting recess 19. An installation tube 20 is rotatably connected between the inner walls of the outer shell 23 and the inner walls of the mounting recess 19. Multiple installation nozzles are fixedly connected to the bottom of the installation tube 20. One end of the installation tube 20 passes through the mounting recess 19 and the drive outer shell 23 and is rotatably connected to an installation telescopic tube 21. The end of the installation telescopic tube 21 passes through the dyeing vat body 2 and extends to the outside of the dyeing vat body 2. An installation valve is connected to the side wall of the installation telescopic tube 21. An installation gear 22 is fixedly sleeved on the outer wall of the installation tube 20. A drive self-locking motor 24 is fixedly connected to the inner wall of the drive outer shell 23. A drive gear 25 is fixedly connected to the output shaft of the drive self-locking motor 24. The drive gear 25 meshes with the installation gear 22. The compensation component achieves the purpose of adjusting the fabric up and down to compensate for the dye.

[0021] Working principle: When in use, the first step is to feed the fabric into the feeding channels 11 on both sides. Then, the self-locking motor 12 on the outside of the feeding channel 11 is started. The self-locking motor 12 drives the moving roller 13 to rotate continuously. The fabric is smoothly fed into the dyeing vat body 2 by relying on the friction of the roller.

[0022] After the fabric is fed into the dyeing vat, the self-locking motor 26 fixed on the outside of the dyeing vat is started. The self-locking motor 26 drives the fixed roller 27, the fixed plate 28 and the transmission roller 29 to rotate synchronously. The transmission roller 29 tensions and limits the fabric in the vat to prevent the fabric from stacking and tangling, and ensures that all areas of the fabric can fully contact the dye liquor.

[0023] Next, start the circulating spray dyeing system and turn on the material pump 9 on the back of the dyeing vat. The material pump 9 draws the prepared dyeing liquid through the first material pumping pipe 10. After the dyeing liquid is pressurized by the pump body, it flows into the second material pumping pipe 8 and then is divided into four regulating branch pipes 7, which are respectively delivered to the corresponding regulating ring pipes 5. After the dyeing liquid fills the ring pipe, it is sprayed inward at high speed from multiple sets of regulating nozzles 6 on the pipe wall, spraying the fabric from all directions around the vat to form a ring-shaped circulating dyeing liquid flow, which disperses the eddies and deviations in the vat.

[0024] The heating module 4, which is sleeved on the outside of the dyeing vat body 2, continuously and evenly heats the vat body to maintain the constant temperature required for the dyeing process and ensure uniform coloring.

[0025] Then, the internal compensation spraying mechanism is activated to eliminate fabric accumulation and dyeing dead spots such as the four corners of the dyeing vat. First, the movable self-locking motor 16 on the side wall of the dyeing vat is activated. The movable self-locking motor 16 drives the movable screw 17 to rotate, and the movable plate 15 is driven to move along the two movable guide rods 14 by the thread transmission, thereby adjusting the overall position of the compensation component to adapt to the fabric in different positions.

[0026] After the horizontal adjustment is completed, start the electric telescopic rod 18, push the mounting recess 19 to make slight up and down adjustments, open the mounting valve on the side wall of the mounting telescopic tube 21, and the externally added dye liquid is introduced into the mounting tube 20 through the mounting telescopic tube 21, and then sprayed downwards from the bottom of multiple sets of mounting nozzles.

[0027] Simultaneously, the self-locking motor 24 inside the drive housing 23 is activated. The self-locking motor 24 drives the drive gear 25 to rotate. The drive gear 25 meshes with the mounting gear 22, driving the mounting tube 20 to rotate back and forth, realizing bottom dye liquor rotational sweeping, continuously replenishing sprays to dead corners that cannot be covered by conventional spraying, and balancing the dye liquor concentration in various parts of the tank.

[0028] The entire spraying, compensation, and temperature control system operates synchronously and continuously. The fabric moves slowly and continuously under the tension of the transmission rollers 29, ensuring full contact with the constant temperature dye liquor in all directions and without dead angles, thus achieving uniform coloring.

[0029] After the fabric dyeing process is completed, the feeding pump 9, each motor and heating module 4 are turned off in sequence, and the moving roller 13 inside the feeding channel 11 is rotated in reverse to transport the finished fabric out of the feeding channel 11, so that the next batch of fabric dyeing operation can be carried out.

[0030] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
