Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing and dyeing equipment technology, and in particular to an auxiliary dyeing mechanism for ramie fabric. Background Technology
[0002] Ramie fabric is a natural fiber fabric, primarily derived from the fibers of the ramie plant. Due to its excellent breathability, moisture absorption, and antibacterial properties, ramie fabric is widely used in clothing and home textiles. However, because of its relatively coarse and stiff fiber structure and numerous gaps, ramie fabric has a low dye uptake rate during the dyeing process, making dyeing difficult and severely limiting its use.
[0003] The current conventional solution is to add dyeing accelerators to the dyeing process of ramie fabric to improve the dye uptake rate and ensure the dyeing effect. However, the use of existing dyeing accelerators mostly involves directly immersing the ramie fabric in the accelerator solution, which requires a relatively long soaking time for the accelerator to act on the ramie fibers, thus significantly affecting the dyeing efficiency of the ramie fabric. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an auxiliary dyeing mechanism for ramie fabric.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An auxiliary dyeing mechanism for ramie fabric includes a dyeing accelerator tank, a dyeing accelerator platform and guide rollers 1 and 2 located on both sides of the dyeing accelerator platform. The ramie fabric in the dyeing accelerator tank is conveyed sequentially through guide rollers 1, the dyeing accelerator platform and guide rollers 2. A conveying pipe for conveying dyeing accelerator is provided above the dyeing accelerator platform. A pressure roller is pressed against the dyeing accelerator platform, and the pressure roller rolls along the dyeing accelerator platform and presses down on the ramie fabric on the dyeing accelerator platform.
[0007] Preferably, the dyeing station has an inner cavity, and the upper end of the dyeing station is provided with a downwardly recessed groove. The groove is provided with a discharge hole that communicates downward with the inner cavity. A piston block is slidably disposed inside the inner cavity and is fitted against the inner wall of the inner cavity.
[0008] Preferably, a sealing ring is fixed to the outer periphery of the piston block, and the sealing ring abuts against the inner wall of the inner cavity.
[0009] Preferably, the dyeing stage is connected to a return pipe that runs through the inner cavity.
[0010] Preferably, the staining station is equipped with a second cylinder, the output end of which is connected upward to a piston block.
[0011] Preferably, the dyeing tank is provided with an installation plate, and a cylinder is fixed on the installation plate. The output end of the cylinder is connected to the pressure roller.
[0012] Preferably, the pressure roller is rotatably connected to the slide, and a fixing frame is provided on the mounting plate, with a sliding groove provided on the fixing frame for guiding the slide.
[0013] Preferably, the dyeing table is provided with a partition that separates the dyeing tank, the partition dividing the dyeing tank into an immersion chamber corresponding to guide roller one and a dyeing chamber corresponding to guide roller two.
[0014] The beneficial effects of this utility model are:
[0015] A pressure roller capable of reciprocating and pressing against ramie fabric is installed on the dyeing accelerator table. During the process of the pressure roller pressing against the ramie fabric fibers, the dyeing accelerator is conveyed through the feed pipe. That is, by pressing and squeezing the ramie fabric with the pressure roller, the fibers of the ramie fabric are made softer and looser, so that the dyeing accelerator can act better on the fibers of the ramie fabric, thereby improving the subsequent dyeing effect of the ramie fabric. At the same time, by pressing and softening the ramie fabric fibers, the reaction efficiency between the dyeing accelerator and the ramie fabric is improved, thereby indirectly improving the dyeing processing efficiency of the ramie fabric.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0022] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] like Figures 1-4 As shown, an auxiliary dyeing mechanism for ramie fabric includes a dyeing tank 1, a dyeing table 2 and guide rollers 11 and 26 on both sides of the dyeing table 2. The ramie fabric 4 in the dyeing tank 1 is conveyed sequentially through the guide rollers 11, the dyeing table 2 and the guide rollers 26. The ramie fabric 4 is input into the dyeing tank 1 and wrapped around the guide rollers 11, and then output outward after passing through the dyeing table 2 and the guide rollers 26.
[0024] The dyeing table 2 is provided with a partition 13 that separates the dyeing tank 1. The partition 13 divides the dyeing tank 1 into an immersion chamber 14 corresponding to the first guide roller 11 and a dyeing chamber 15 corresponding to the second guide roller 16. The immersion chamber 14 is filled with clean water. When the ramie fabric 4 is wrapped around the first guide roller 11, it is washed and wetted by the clean water in the immersion chamber 14.
[0025] Above the dyeing accelerator 2, there is a conveying pipe 22 for conveying the dyeing accelerator. The conveying pipe 22 has a through hole so that the dyeing accelerator can be conveyed to the ramie fabric 4 on the dyeing accelerator 2 through the through hole of the conveying pipe 22. The upper end of the dyeing accelerator 2 is provided with a downwardly recessed trough 23. The trough 23 can temporarily hold the dyeing accelerator to prevent the dyeing accelerator conveyed by the conveying pipe 22 from flowing into the dyeing tank 1 through the dyeing accelerator 2, thereby causing waste of the dyeing accelerator.
[0026] Furthermore, by using the trough 23 to accommodate the dyeing accelerator, the ramie fabric 4 conveyed on the dyeing table 2 can be better immersed in the dyeing accelerator, thereby allowing the dyeing accelerator to act better on the fibers of the ramie fabric 4.
[0027] The dyeing accelerator 2 has an inner cavity 21, and the container 23 has a discharge hole 26 that communicates downward with the inner cavity 21. The dyeing accelerator on the container 23 can flow into the inner cavity 21 through the discharge hole 26. A piston block 24 is slidably installed in the inner cavity 21. Specifically, the dyeing accelerator 2 is equipped with a second cylinder 25. The output end of the second cylinder 25 is connected upward to the piston block 24. The second cylinder 25 drives the piston block 24 to slide up and down along the inner wall of the inner cavity 21, thereby allowing the dyeing accelerator in the inner cavity 21 to be transported back to the container 23 through the discharge hole 26, so that the dyeing accelerator can act more fully and efficiently on the ramie fabric 4, and at the same time improve the utilization rate of the dyeing accelerator.
[0028] The piston block 24 is fitted to the inner wall of the inner cavity 21, and a sealing ring 241 is fixed to the outer periphery of the piston block 24. The sealing ring 241 abuts against the inner wall of the inner cavity 21 to prevent the dyeing agent from seeping out from the gap between the piston block 24 and the side wall of the inner cavity 21.
[0029] Furthermore, the dyeing station 2 is connected to a return pipe 211 that runs through the inner cavity 21. The return pipe 211 is positioned higher than the piston block 24, and the dyeing agent in the inner cavity 21 can be recovered through the return pipe 211 to recycle the dyeing agent.
[0030] A pressure roller 3 is mounted on the dyeing accelerator table 2, and a mounting plate 12 is mounted on the dyeing accelerator tank 1. A cylinder 121 is fixed on the mounting plate 12, and the output end of the cylinder 121 is connected to the pressure roller 3, so that the cylinder 121 drives the pressure roller 3 to reciprocate on the upper end of the dyeing accelerator table 2.
[0031] Specifically, the pressure roller 3 is rotatably connected to the slide 31, and a fixed frame 32 is provided on the mounting plate 12. The fixed frame 32 is provided with a sliding groove 33 for the slide 31 to slide and guide. The slide 31 drives the pressure roller 3 to move back and forth along the length of the sliding groove 33, so that the pressure roller 3 rolls along the dyeing table 2 and presses down on the ramie fabric 4 on the dyeing table 2.
[0032] Then, as the pressure roller 3 moves back and forth, it rolls, presses, and squeezes the ramie fabric 4 on the dyeing table 2, making its fibers softer and looser, so that the dyeing agent can better act on the fibers of the ramie fabric 4, thereby improving the subsequent dyeing effect of the ramie fabric 4.
[0033] At the same time, the fibers of the ramie fabric 4 are softened by the pressure roller 3, which improves the reaction efficiency between the dyeing agent and the ramie fabric 4, thereby indirectly improving the dyeing processing efficiency of the ramie fabric 4.
[0034] Furthermore, the dye solution to be dyed for the ramie fabric 4 is injected into the dyeing chamber 15. After the ramie fabric 4 reacts with the dyeing accelerator on the dyeing accelerator table 2, it can be immediately transported to the dyeing chamber 15 for preliminary dyeing, so as to improve the subsequent dyeing effect and efficiency of the ramie fabric 4.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
