Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant fiber dyeing device, in particular to a plant dyeing fiber raw material processing technology and equipment for blending. BACKGROUND

[0002] Plant dyeing fiber raw materials include pure cotton, flax, cotton-flax blended fabric, bamboo fiber, etc. These plant fiber fabrics are easy to find and relatively cheap, suitable for practice or making finished products. However, the adhesion effect of plant dyes on these fibers may not be as good as animal fibers, and the dyed color may be lighter or prone to color loss. In order to improve the dyeing effect, mordanting treatment can be carried out.

[0003] The existing cotton processing equipment generally processes blended plant dyeing fibers by pre-processing cotton with large equipment. The processing is carried out by passing the cotton through a humidifier to wet the surface of the cotton, then passing the cotton through a cotton press to remove the seeds under pressure, then passing the cotton through a cotton picker to remove the cotton fibers outside the seeds. The inside of the cotton picker has multiple rotating rollers to separate the cotton fibers and their seeds. Finally, the cotton and impurities are removed by a vibrating machine. Since the gravity of cotton is relatively light, impurities are easily dropped below the equipment after vibration. Finally, the seeds and impurities are separated by a screening machine to complete the entire cotton fiber processing process.

[0004] In the traditional production process of cotton, the cotton needs to be pretreated in a relatively complex way, including opening cotton, cleaning cotton, and loosening cotton, etc. Although impurities can be removed, the processing procedure is complex, the equipment occupies a large area, the cost is uncontrollable, and the processing method involves wetting treatment. In the subsequent cotton picking process, the gravity of cotton is relatively large, and some color impurities have small particle size, which are difficult to pick and separate directly. Moreover, it is also difficult to completely remove the impurities mixed in the cotton fibers during vibration and screening, which affects the processing efficiency of cotton and the processing quality of subsequent cotton fibers, and further affects the quality of cotton textiles. Therefore, we propose a plant dyeing fiber raw material processing technology and equipment for blending. SUMMARY

[0005] The present application aims to provide a plant dyeing fiber raw material processing technology and equipment for blending to solve the problems raised in the background.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a plant dyeing fiber raw material processing technology for blending, comprising a machine box, specifically comprising the following steps: Refining process: First, the cotton raw material is put into the machine for impurity removal. After the impurities are removed, the cotton is taken out manually and put into the treatment pot. 2%-3% caustic soda and 0.5% of the fabric weight of additive-free soap are used to boil in clean water for 2 hours. This process effectively removes impurities such as wax and pectin from the fiber surface and improves the uniformity of subsequent dyeing. After completion, it is necessary to wash and dry it thoroughly to avoid alkaline residue affecting the dyeing. Desizing and washing: Soak the cotton in 60°C hot water for 6-8 hours to remove industrial sizing through biological enzyme decomposition or theophylline treatment. Incomplete desizing will cause dyeing spots, so it is necessary to rub and wash with soap to fully expose the fibers. Soy milk protein optimization: Soak cotton wool in raw soy milk for 20 minutes. The plant protein in the soy milk fills the fiber pores and forms a dyeing buffer layer, which significantly improves the color adhesion. After processing, it needs to be flattened and dried to prevent wrinkles. Dye extraction technology: Pigments are extracted from raw materials such as sappanwood and indigo through differential extraction: woody materials need to be boiled for 2 hours, while root and rhizome materials are cold-soaked and fermented (such as indigo mud). After filtration, a dye solution with a stable pH value is obtained, and the concentration is adjusted by the boiling time. Dynamic dyeing control: The cotton fibers must be fully expanded in the dye bath, and the silk must be kept at a low temperature of 40-60°C to prevent damage. The cotton fibers need to be turned over intermittently. The dyeing time is adjusted according to the target color level, 30 minutes for light colors and up to 8 hours for dark colors with repeated immersion. Synergistic effect of mordants: Alum (potassium aluminum sulfate) gives madder a red color, while iron mordant turns it dark brown; tin salts enhance color brightness, and copper salts produce a blue-green hue. The concentration of the mordant solution must be strictly controlled (0.5%-5%), as excessive amounts can lead to fiber embrittlement. Biological re-fixation: Dark colors require 3-5 alternating dips and oxidations. For indigo dyeing, each dip lasts 20 minutes, followed by 30 minutes of oxidation. Before each re-dyeing, surface excess dye must be removed to ensure molecular-level bonding.

[0008] Preferably, a plurality of second through holes are formed in the other end of the guide plate, and a hopper plate is fixedly connected between the machine box and the material guide pipe.

[0009] Preferably, a second motor is fixedly installed at one end of the air guide pipe, the output shaft of the second motor and the spiral blade shaft are connected together by a belt, a first motor is fixedly installed at one end of the machine box, and the output shaft of the first motor and the screw rod are connected together by a belt.

[0010] Preferably, a plurality of second magnets are fixedly connected to the inner ring of each cotton suction roller in a ring shape, a first magnet is fixedly connected to the outer ring of the inner rotating rod near each second magnet, the magnetic poles of the first magnet and the second magnet are opposite, and the opposite magnetic poles attract each other, a cutting knife is fixedly installed at the outer ring of each first magnet, the cutting knife extends out of the cotton suction roller through the second magnet, a plurality of fixed discs are fixedly installed on the cotton suction roller, a plurality of cotton grabbing needles are fixedly installed at the outer ring of each fixed disc, and the end of the cotton grabbing needle is close to the outer extension of the spiral blade.

[0011] Preferably, a brake wheel is fixedly connected to the outer ring of one end of each cotton suction roller, a cylinder is fixedly connected to the upper and lower parts of the outer edge of the moving plate, a first driving rod is fixedly connected to the top of the cylinder rod of the cylinder located at the upper part of the moving plate, a second driving rod is fixedly connected to the top of the cylinder rod of the cylinder located at the lower part of the moving plate, and the downward movement of the bottom of the first driving rod and the upward movement of the second driving rod form an interference area of the brake wheel.

[0012] Preferably, a pair of guard rings are slidingly connected to the inside of the moving plate, the outer ring of one end of each inner rotating rod is connected together with the pair of guard rings, a spring is fixedly connected between the inside of the moving plate and the opposite faces of each cylinder, and one end of the spring abuts against the inner rotating rod.

[0013] Preferably, slide rails are fixedly installed on the top of the machine box, a supporting rod is slidingly connected between the two slide rails, a third motor is fixedly installed on the supporting rod, a first gear is sleeved on the output shaft of the third motor, a second gear is fixedly installed on one side of the rotating cylinder, and the first gear and the second gear are engaged together.

[0014] Preferably, the materials of the conical column and the rotating cylinder are made of anti-skid materials.

[0016] Compared with the prior art, the present application has the following advantages: 1. During the rotation of the first motor of the present invention, the lead screw rotates. During the rotation of the lead screw, the moving plate moves away from one end of the guide tube, and the moving plate drives the rotating rod to move. During the movement of the rotating rod, the inner rotating rod is pulled outward, and the inner rotating rod drives the cotton suction roller to move. When the cotton suction roller is pulled out of the guide tube, the cotton lint on the cotton suction roller is pulled out of the guide tube, while a portion of the cotton lint is retained inside the guide tube. At the same time, the second motor is driven to rotate in both directions, so that the remaining cotton lint is discharged directly onto the hopper plate through the second through hole. Then the vibrator is turned on to work, and finally the cotton lint falls onto the vibrator through the hopper plate. This reduces the workload of the vibrator in processing cotton lint per cycle and improves the efficiency and accuracy of impurity removal. 2. In this invention, when each cotton suction roller exits the guide tube, and then moves to the outside along with the moving plate, two cylinders are simultaneously driven to descend, causing the ends of the first and second drive rods to abut against the brake wheel. The rotating cylinder continues to drive the conical column to rotate, causing the first and second magnets to separate from each other. This allows the cutting blade to cut and shred the cotton lint on the cotton-grabbing needle, breaking the cotton lint into smaller pieces, reducing the weight of the cotton lint clump, and causing the cotton lint to fall onto the inclined plate above the machine box, and then roll onto the vibrator, which helps to better remove impurities from the cotton lint.

After the cotton wadding is removed, the cotton wadding is taken out by hand, and the cotton wadding after impurity removal is put into a treatment pot. 2%-3% caustic soda and 0.5% soap without addition are used to boil the cloth in clean water for 1 hour.

The plant protein in the soybean milk fills the fiber pores and forms a dyeing buffer layer, which significantly improves the color adhesion. After treatment, it needs to be flattened and aired to prevent wrinkles; Dye extraction technology: raw materials such as logwood and blue grass extract pigments by difference method: wood needs to be boiled for 2 hours, and rhizome adopts cold soaking fermentation (such as blue indigo mud).

The concentration of mordant solution needs to be strictly controlled (0.5%-5%), and excessive amount will cause fiber brittleness; Biological re-fixing: deep color systems need 3-5 times of alternating dip and oxidation, and indigo dye needs to be taken out for oxidation for 30 minutes every 20 minutes of immersion. Surface floating color needs to be removed before each re-dyeing to ensure molecular level combination.
