Textile fabric bleaching device for textile processing

Abstract

This invention discloses a textile bleaching device, comprising a bleaching box, connecting columns mounted on both sides of the top of the bleaching box, and a spray box mounted on top of the connecting columns. The spray box contains a spray trough, and two forward and backward rollers are rotatably mounted on both sides of the spray trough. Baffles are mounted on the front and rear sides of each roller, and a liftable pressure plate is installed between the front and rear baffles. A guide pipe is installed at the bottom of the spray box. This textile bleaching device, equipped with rollers, pre-winds half of the textile fabric onto one roller during bleaching, while the other half is immersed in the bleaching tank. The end of the immersed textile fabric is pulled up and fixed onto the other roller. Thus, when the two rollers rotate synchronously, one roller places the textile fabric into the bleaching tank, while the other roller winds up the textile fabric in the bleaching tank. After winding up half of the textile fabric, the rotation direction of the rollers is changed, and the bleaching process is repeated cyclically.

Description

Technical Field

[0001] This invention relates to the field of textile bleaching equipment, specifically a textile bleaching equipment for textile processing. Background Technology

[0002] In chemistry, bleaching refers to the process of turning a colored material white through a series of chemical reactions. Bleaching can oxidize or reduce the chromophores of organic colored substances, but it does not destroy the basic substances of the organic colored substances. Natural fiber textiles contain natural or additional colored substances, which remain even after scouring and require bleaching to remove the color.

[0003] Existing methods for bleaching textiles generally involve immersing the textiles in water and then using an agitation mechanism to move the bleach solution, thereby improving the bleaching efficiency of the submerged textiles. However, these methods still have certain drawbacks: 1. When the existing bleaching device uses the stirring mechanism to drive the bleaching liquid to rotate, the textiles will be driven to rotate together. During the rotation, the textiles are easy to get tangled together, making it inconvenient to quickly rewind them when taking them out later. 2. After the existing bleaching equipment has finished bleaching, it is difficult to wring out the textiles. The textiles need to be taken out manually and put into the wringing mechanism to squeeze out most of the bleach. The use of this equipment requires manual contact with the bleach, which is harmful to the human body. Summary of the Invention

[0004] The purpose of this invention is to provide a textile bleaching device for textile processing, so as to solve the problems mentioned in the background art, which are that stirring the bleaching solution during textile bleaching can easily cause the textile to entangle and that the wringing process is cumbersome.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a textile bleaching device, comprising a bleaching box, for textile processing. The bleaching box has connecting columns installed on both sides of its top, and a spray box is mounted on top of the connecting columns. The spray box has a spray trough, and a front-to-back roller is rotatably installed on both sides of the spray trough. Baffles are installed on the front and back sides of the rollers, and a liftable pressure plate is installed between the front and back baffles. A guide pipe is installed at the bottom of the spray box, and an opening is opened at the bottom of the spray box where it is aligned with the guide pipe. The top of the spray box is equipped with a spraying mechanism for spraying the textile on the rollers. The spray box is also equipped with a transversely movable extrusion mechanism. The back of the spray box is equipped with a drive mechanism for driving the two rollers to rotate synchronously.

[0006] By adopting the above technical solution, during use, one end of the textile is fixed to a roller on one side by the lowering of the pressure plate. Then, the drive mechanism drives the rotation of the roller to wind up half of the textile. After winding, the other half of the textile is passed through the guide tube below the roller and immersed in the bleaching tank. Then, the unfixed end of the textile is passed through the guide tube on the other side and fixed to the roller on the other side. The drive mechanism is then started to achieve the back-and-forth winding and unwinding effect of the textile. After one roller winds up half of the textile, the rotation direction of the roller is changed to bleach in a cycle. Compared with the existing method of improving the bleaching effect by agitating the bleaching liquid, this method can avoid the tangling of the textile and the textile can be easily wound up after bleaching.

[0007] As a further aspect of the present invention: the bleaching box has a bleaching tank inside, and the bleaching tank contains bleaching liquid. One end of a water pipe is connected to the back of the bleaching box. A liftable filter screen is installed inside the bleaching box, and the filter screen is located at the connection between the bleaching box and the water pipe.

[0008] By adopting the above technical solution, during use, the bleaching liquid input into the spraying mechanism from the bleaching tank is filtered through a filter screen to prevent lint from falling into the bleaching tank from entering the spraying mechanism.

[0009] As a further aspect of the present invention: a U-shaped collection frame is installed at the front end of the filter screen, a T-shaped guide strip is installed on the back of the filter screen, a T-shaped guide groove is opened on the back of the bleaching box, and the guide strip on the back of the filter screen is located in the T-shaped guide groove.

[0010] By adopting the above technical solution, the design of the collection frame on the filter screen facilitates the collection of lint, and the design of the guide strip facilitates the up and down guidance of the filter screen.

[0011] As a further aspect of the present invention: the spraying mechanism includes a spray frame, two spray frames are installed on the inner top of the spray box, the two spray frames are respectively located above two rollers, multiple spray heads are distributed at the bottom front and back of the spray frame, a connecting pipe is connected between the two spray frames, and the top of the connecting pipe is connected to the other end of the water pipe, and a liquid pump is installed on the back of the spray box, and the liquid pump is installed on the water pipe.

[0012] By adopting the above technical solution, during use, the liquid pump delivers the bleaching liquid in the bleaching tank to the connecting pipe through the water pipe. The connecting pipe guides the bleaching liquid to the spray racks and spray heads on both sides to spray and bleach the textile on the roller, thus avoiding the situation where the ends of the textile fixed by the roller cannot be bleached.

[0013] As a further aspect of the present invention: the extrusion mechanism includes an extrusion roller, and a front-to-back extrusion roller is rotatably installed inside the spray box, with the extrusion roller and the roll roller at the same horizontal height. A moving groove is provided on the front and rear walls of the spray box at a position aligned with the extrusion roller, and the front and rear rotating shafts of the extrusion roller both pass through the moving groove. A moving plate is provided at one end of the rotating shaft of the extrusion roller located outside the spray box, and the end of the rotating shaft of the extrusion roller is inserted into the moving plate. A second motor is installed on the outside of the moving plate, and the output shaft of the second motor is connected to the rotating shaft of the extrusion roller.

[0014] By adopting the above technical solution, when in use, motor two can drive the rotation of the extrusion roller, which facilitates the rotation when the extrusion roller contacts the roll roller. It should be noted that the rotation direction of the extrusion roller is opposite to that of the roll roller.

[0015] As a further aspect of the present invention: hydraulic cylinders are installed on both the front and rear walls of the spray box, and protruding plates are installed on the side walls of the moving plate, with the output shaft of the hydraulic cylinders connected to the protruding plates on the moving plate.

[0016] By adopting the above technical solution, when bleaching is completed, the pressure plate on the roll away from the extrusion roller rises and releases the clamping of the textile. The other roll continues to roll up the textile under the drive of the drive mechanism, and the extrusion roller gradually approaches the roll with the drive of the hydraulic cylinder, which has the effect of squeezing the textile on the roll, thus reducing the amount of bleach in the textile.

[0017] As a further embodiment of the present invention: the driving mechanism includes a rotating shaft, a transverse rotating shaft is mounted on the back of the spray box via a mounting base, and worm gears are mounted on both sides of the rotating shaft. The rear ends of the rotating shafts of the two rollers extend through the back of the spray box, and worm wheels are mounted on the rear ends of the rotating shafts of the rollers. The two worm wheels mesh with the two worm gears respectively. A motor for driving the rotating shaft to rotate is mounted on the back of the spray box.

[0018] By adopting the above technical solution, during use, the rotation of the rotating shaft is driven by the motor, which in turn drives the rotation of the two worm gears, which in turn drives the worm wheels on the two rollers to rotate, thus achieving the effect of synchronous rotation of the two rollers.

[0019] As a further aspect of the present invention: a control panel is installed on the outside of the bleaching box, and the control panel is electrically connected to the electrical components inside the device.

[0020] By adopting the above technical solution, the start and stop of the electrical components inside the device can be controlled through the control panel during use.

[0021] As a further aspect of the present invention: a lifting groove is provided on the baffle, and nuts are installed at both ends of the pressure plate, with the nuts inserted into the lifting groove. An adjusting screw is rotatably installed in the lifting groove, and the adjusting screw is threadedly connected to the nuts. A motor is installed on the outside of the baffle, and the motor is used to drive the rotation of the adjusting screw.

[0022] By adopting the above technical solution, during use, the motor can drive the rotation of the adjusting screw, and then the height of the pressure plate can be adjusted by the threaded connection between the adjusting screw and the nut, which facilitates the clamping and releasing of textiles.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the textile bleaching device for textile processing, (1) A roller is provided. During bleaching, half of the textile is pre-wound onto one of the rollers, and the other half is placed in the bleaching tank for soaking. The end of the soaked textile is pulled up and fixed onto another roller. When the two rollers rotate synchronously, one roller puts the textile into the bleaching tank, while the other roller rolls up the textile in the bleaching tank. After rolling up half of the textile, the rotation direction of the roller is changed, and bleaching is carried out in a cycle. Compared with the existing method of improving the bleaching effect by stirring the bleaching liquid, this method can avoid the textile from tangling, and the textile can be easily rolled up after bleaching. (2) It is equipped with a squeezing roller, a moving plate, a hydraulic cylinder and a second motor. The hydraulic cylinder can drive the squeezing roller and the moving plate to move laterally as a whole, so that the squeezing roller contacts the winding roller. The second motor drives the squeezing roller to rotate, thereby squeezing the textile during winding and replacing the process of manually taking out the textile and wringing it dry. (3) It is equipped with a connecting pipe, a water pipe, a spray frame, a spray head and a liquid pump. The liquid pump uses the water pipe to transport the bleaching liquid in the bleaching tank to the connecting pipe. The bleaching liquid in the connecting pipe flows to the spray frame on both sides and is sprayed onto the roller through the spray head, so as to achieve the bleaching effect on both ends of the fixed textile.

The back of the spray box 3 is mounted with a transverse rotating shaft 17 via a mounting base 16, and worm gears 18 are mounted on both sides of the rotating shaft 17. The rear ends of the rotating shafts of the two rollers 9 extend through the back of the spray box 3, and worm wheels 19 are mounted on the rear ends of the rotating shafts of the rollers 9. The two worm wheels 19 mesh with the two worm gears 18 respectively. A motor 20 for driving the rotating shaft 17 to rotate is mounted on the back of the spray box 3.

[0034] Please see Figure 1Furthermore, a control panel 25 is installed on the outside of the bleaching box 1, and the control panel 25 is electrically connected to the electrical components inside the device.

[0035] Please see Figure 3 Furthermore, a lifting groove 1001 is provided on the baffle 10, and a screw nut is installed at both the front and rear ends of the pressure plate 11. The screw nut is inserted into the lifting groove 1001. An adjusting screw 1002 is rotatably installed in the lifting groove 1001, and the adjusting screw 1002 is threadedly connected to the screw nut. A motor 1003 is installed on the outside of the baffle 10, and the motor 1003 is used to drive the rotation of the adjusting screw 1002.

[0036] Working principle: When using this textile bleaching device, one end of the fabric is fixed to a roller 9 on one side by the lowering of the pressure plate 11. The drive mechanism then rotates the roller 9 to wind up half of the fabric. After winding, the other half of the fabric passes through the guide tube 4 below the roller 9 and is immersed in the bleaching tank 101. The unfixed end of the fabric then passes through the guide tube 4 on the other side and is fixed to the roller 9 on the other side. Activating the drive mechanism then achieves the back-and-forth winding and unwinding effect of the fabric. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) After the textile is half-wound, the rotation direction of the roller 9 is changed, and bleaching is carried out in a cycle. Compared with the existing method of improving the bleaching effect by stirring the bleaching liquid, this method can avoid the textile from tangling, and the textile can be easily wound up after bleaching. During bleaching, the liquid pump 21 delivers the bleaching liquid in the bleaching tank 101 to the connecting pipe 5 through the water pipe 6. The connecting pipe 5 guides the bleaching liquid to the spray frame 7 and spray head 8 on both sides to spray the textile on the roller 9 for bleaching, avoiding the situation where the end of the textile fixed by the roller 9 cannot be bleached. After bleaching is complete, the pressure plate 11 on the winding roller 9, which is away from the extrusion roller 12, rises under the drive of the motor 1003, releasing the clamping of the textile. The winding roller 9 on the other side continues to wind up the textile under the drive of the drive mechanism, and the extrusion roller 12 gradually approaches the winding roller 9 under the drive of the hydraulic cylinder 14, squeezing the textile on the winding roller 9 to reduce the amount of bleach in the textile.
