Description

A kind of bleaching device and bleaching method of textile fabric for textile processing

technical field

The invention relates to the technical field of textile fabric bleaching, in particular to a bleaching device and a bleaching method for textile fabrics for textile processing.

Background technique

Textile machinery is all kinds of machinery and equipment required to process natural fibers or chemical fibers into textiles. Although the machinery for producing chemical fibers includes a variety of chemical machinery, it is now considered to be an extension of textile machinery, which is a generalized textile machinery. According to the production process, there are: spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber drawing equipment, silk reeling equipment and non-woven fabric equipment. Printing and dyeing is also called dyeing and finishing. The existing steps of producing textile cloth are: using a printing and dyeing roller to press the textile cloth to press a color layer on the surface of the textile cloth; then drying the printing and dyeing cloth by using a drying tunnel to dry the pigments printed on the surface of the textile cloth , and finally the finished textile fabric after drying is rolled up by the winding device.

When the user needs to remove the color layer on the textile cloth or needs to replace another color, the colored textile cloth needs to be bleached with a bleaching solution, and then rolled up for continued use after bleaching. The existing bleaching method is to soak the textile cloth in a water tank containing a bleaching liquid, bleach the color layer attached to the surface of the textile cloth by the bleaching liquid, and spray and rinse the textile cloth after bleaching to remove the dye on the textile cloth. The residual bleaching solution is then dried in a drying tunnel, and the textile fabrics are collected for reuse after drying. However, although this bleaching method can complete the bleaching of the color layer, it still has the following defects: 1. When the textile cloth is salvaged from the sink containing the bleaching liquid, a large amount of bleaching liquid is attached to the textile cloth, and these The bleach solution is directly rinsed off with clean water, which wastes the bleach solution and increases the cost of bleaching. 2. When the traditional spray method is used to wash the textile cloth, the washing is not complete. The main reason is that the direction of the spray water is always unchanged, resulting in that the bleaching liquid on the textile cloth in some local areas has not been washed clean, and there is flushing. Incomplete flaws. 3. During the rinsing process in the sink, the bleaching liquid is always stagnant, resulting in a small contact area between the bleaching liquid and the textile fabric, and it takes a long time to soak it cleanly, which reduces the bleaching efficiency. A bleaching device for textile fabrics for textile processing that can improve bleaching efficiency, save bleaching costs, and can thoroughly rinse off the bleaching solution remaining on the textile fabrics.

On the right end face, the PLC controller (45) is electrically connected to the motor A (12), the motor B (23), the motor C (42), the longitudinal cylinder (13) and the clamping cylinder (18). 9. The method for bleaching textile fabrics for textile processing by a bleaching device according to any one of claims 1 to 8, characterized in that it comprises the following steps: S1. Pull out the head end of the textile cloth on the rewinding drum (41), and pass the head end of the textile cloth (46) through the right guide wheel (8), the middle wheel (9), and the left guide wheel (7) in sequence. ), then fold the textile cloth (46) by 90° and pass its head end through the area formed between the two vertical guide wheels (15), the area formed by the two pressure rollers (20), the first The second U-shaped frame (22) and the third U-shaped frame (32) are finally fixed on the winding drum (41); S2. The worker operates the piston rods of the two clamping cylinders (18) to extend, and the piston rods drive the pressure rollers (20) to move relative to each other. When the two pressure rollers (20) are pressed on the textile cloth (46); S3. The worker pours a certain amount of bleaching solution into the water tank (6) to ensure that the liquid level of the bleaching solution is lower than the rectangular frame (14), and the bleaching solution bleaches the bleaching solution located between the left guide wheel (7) and the right guide wheel (8). Textile cloth (46); turn on the motor A (12) at the same time, the motor A (12) drives the rotating drum (10) to rotate, the rotating drum (10) drives the blade (11) to rotate, and the blade (11) stirs the bleaching solution to increase the The contact area between the bleaching liquid and the textile fabric reduces the bleaching time and improves the bleaching efficiency; S4. The worker turns on the motor C (42), the motor C (42) drives the reel (41) to rotate, and the reel (41) winds the bleached textile cloth (46) on it. When the textile cloth (46) enters the two vertical guide wheels (15), the bleached textile cloth (46) emerges from the bleaching solution and changes from a horizontal state to a vertical state; The cylinder (13) makes its piston rod move back and forth, the piston rod drives the rectangular frame (14) to move back and forth, and the vertical guide wheel (15) drives the textile cloth (46) inside it to move back and forth, so that the Most of the bleaching solution attached to the textile cloth (46) is thrown into the water tank (6), thereby preventing the bleaching solution from being carried out along with the textile cloth, so that the dropped bleaching solution can continue to be used, thereby saving the cost of bleaching ; Then the textile cloth (46) enters the area between the two pressure rollers (20), because the two pressure rollers (20) are pressed on the textile cloth (46), and the textile cloth (46) moves from right to left , the pressing wheel (20) squeezes the residual bleaching liquid attached to the textile cloth (46) into the water tank (6), thereby further avoiding the bleaching liquid being taken out with the textile cloth, so that the squeezed bleaching liquid can be Continue to use, thus saving the cost of bleaching; S5. Washing of the textile cloth: when the textile cloth (46) enters the two side panels of the second U-shaped frame (22), the worker turns on the water pump, and the water pump flows into the horizontal water pipe (29), under water pressure The clean water is sprayed out through the horizontal water pipe (29), the vertical water pipe (30), and the water outlet (31) in sequence, and the clean water sprayed from the water outlet (31) on the two sides of the second U-shaped frame (22) is washed separately. The front and rear surfaces of the textile cloth (46) are washed away from the outer surface of the textile cloth. At the same time, the worker turns on the motor B (23), the motor B (23) drives the cam (26) to rotate, and the cam (26) passes through the first The connecting rod (27) and the second connecting rod (28) drive the disc (25) to rotate back and forth around its center, the disc (25) drives the shaft (24) to rotate back and forth, and the shaft (24) drives the second U-shaped The frame (22) swings back and forth, thereby changing the water outlet direction of the water sprayed from the water outlet hole (31), increasing the washing area of the textile cloth, and making the bleaching solution completely washed out; S6, drying of the textile cloth: when the textile cloth (46) enters the two side panels of the second U-shaped frame (22), the worker turns on the blower (37), and the blower (37) sends the air heater (36) The air is blown in, the air heater (36) heats the air, and the heated air is ejected through the horizontal air inlet pipe (33), the vertical air outlet pipe (34), and the air outlet hole (35) in sequence, and the ejected hot air acts on the onto the front and rear surfaces of the textile cloth (46) to achieve the purpose of drying the textile cloth; S7, the dried textile cloth is wound on the winding drum (41).
