Description

Technical Field

[0001] The invention relates to the technical field of textile processing, in particular to a bleaching and decolorizing device based on textile printing and dyeing. Background Art

[0002] The rinsing and decolorizing equipment for textile printing and dyeing has many functions on textiles, such as removing dye impurities, improving color, and enhancing performance; in the existing rinsing and decolorizing equipment for textile printing and dyeing, the water in the washing tank is continuously circulated and updated, and through the countercurrent rinsing principle, the relatively clean water of the latter washing tank is used to replenish the previous washing tank, thereby improving the efficiency of water resource utilization and removing dyes, auxiliaries and impurities on the fabric to achieve rinsing and decolorization, but multiple washing tanks are arranged in sequence, which requires a larger factory space and increases the site cost of the enterprise; Chinese patent application number: CN202211027110.8 proposes another solution, disclosing a jeans washing and rinsing device, which is provided with a rotating shaft driven by a motor inside the washing tank, and rings are slidably sleeved on both sides of the rotating shaft, and connecting rods distributed in a ring and equidistantly are fixed on the outer wall of the ring, and the connecting rods are away from the rings. A cloth clamp is fixed at one end of the rotating shaft, and the cloth clamps on both sides of the rotating shaft respectively clamp and position the two ends of the denim cloth, so that the denim cloth is unfolded, and the rotating shaft is driven to rotate by the motor, so that the denim cloth can be circulated and rinsed in the rinsing liquid below the washing tank during the rotation process, without the need to completely immerse all the denim cloth in a large amount of rinsing liquid. At the same time, the rinsing water is pumped out by the water pump and sprayed on the denim cloth through the spray mechanism, avoiding the problem that the traditional jeans washing and rinsing device requires a large amount of rinsing liquid and water, thereby wasting water resources, and is prone to insufficient rinsing due to a large amount of denim cloth piled up, and can also avoid the formation of wrinkles; although the above solution solves the problem that multiple washing tanks are arranged in sequence in the existing solution, which requires a large factory space and increases the site cost of the enterprise, the above solution still has the problem that the denim cloth cannot be continuously rinsed and decolorized.

[0003] To this end, a bleaching and decolorizing device based on textile printing and dyeing is proposed to address the problems that the existing bleaching and decolorizing equipment based on textile printing and dyeing requires a large installation space, increases the site cost of the enterprise, and cannot continuously bleach and decolorize denim fabrics. Summary of the Invention

[0004] The purpose of the present invention is to provide a bleaching and decolorizing device based on textile printing and dyeing, so as to solve the problems that the existing bleaching and decolorizing equipment based on textile printing and dyeing requires a large installation space when used, increases the site cost of the enterprise, and cannot continuously bleach and decolorize denim fabrics.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A bleaching and decolorizing device based on textile printing and dyeing, comprising a mounting frame, a No. 1 water washing box, a No. 2 water washing box, a motor and a No. 1 gear set, wherein the No. 1 water washing box, the No. 2 water washing box, the motor and the No. 1 gear set are all mounted on the mounting frame, the No. 1 water washing box is mounted on the upper side of the No. 2 water washing box, a plurality of traction rollers and a tensioning roller are mounted in the No. 1 water washing box and the No. 2 water washing box, a No. 1 nozzle is mounted in the No. 1 water washing box, and a No. 1 drain port is provided on the side of the No. 1 water washing box and the No. 2 water washing box near the box opening, the motor drives the plurality of traction rollers to rotate simultaneously through the No. 1 gear set, and the plurality of traction rollers are used to pull the cloth into the No. 2 water washing box and the No. 2 water washing box in sequence. Rinsing and decolorization are carried out in the No. 1 washing box, and the multiple tensioning rollers are used to adjust the tension of the cloth when the traction roller is driven. The No. 1 nozzle is used to spray clean water onto the surface of the cloth. The water level in the No. 1 washing box rises to the height of the No. 1 drain port and then flows into the No. 2 washing box. The water level in the No. 2 washing box rises to the height of the No. 1 drain port and then flows out through the No. 1 drain port. This avoids the need for a larger installation space when using the rinsing and decolorization equipment based on textile printing and dyeing, which increases the company's site costs, and the problem of being unable to continuously rinse and decolorize denim fabrics, thereby ensuring the space utilization, production continuity and applicability of the rinsing and decolorization equipment based on textile printing and dyeing.

[0007] Preferably, the lateral projections of the No. 1 water washing box and the No. 2 water washing box are V-shaped, the vertical projection of the No. 1 water washing box is located within the vertical projection of the No. 2 water washing box, and the No. 1 tensioning roller, the No. 1 traction roller and the No. 2 traction roller are installed 15-30 cm above the highest point of the front end, the bottom end and the highest point of the rear end of the No. 2 water washing box respectively, and the No. 5 traction roller, the No. 4 traction roller, the No. 3 traction roller and the No. 2 tensioning roller are installed 15-30 cm above the highest point of the front end, the lowest point of the front end, the bottom end and the highest point of the rear end of the No. 1 water washing box respectively. In order to ensure that the cloth can run smoothly in the equipment and avoid friction or jamming with the bottom of the No. 1 washing box and the No. 2 washing box, and taking into account the circulation and spraying effect of the water flow, the cloth is conveyed in sequence through the No. 1 tensioning roller, the No. 1 traction roller, the No. 2 traction roller, the No. 2 tensioning roller, the No. 3 traction roller, the No. 4 traction roller and the No. 5 traction roller, thereby avoiding the problem that floating color, residual additives and impurities in the cloth fall back to the surface of the cloth, resulting in a decrease in the rinsing and decolorization rate, and ensuring the rinsing and decolorization effect of the rinsing and decolorization equipment based on textile printing and dyeing.

[0008] Preferably, the bottoms of the No. 1 washing box and the No. 2 washing box are rotatably connected to a No. 1 crank and a No. 2 crank respectively, one end of the No. 1 crank and the No. 2 crank are rotatably connected to the mounting frame, the other ends of the No. 1 crank and the No. 2 crank are rotatably connected to the No. 1 traction roller and the No. 3 traction roller respectively, the No. 1 traction roller and the No. 3 traction roller are both rollingly connected to the upper end surface of the cloth, and a No. 2 gear set and a No. 3 gear set are installed on the mounting frame, the No. 1 crank is connected to the motor through the No. 2 gear set and rotates counterclockwise, and the No. 2 crank is connected to the motor through the No. 3 gear set and rotates clockwise, avoiding the problem of textile printing based on the printing of the textile. When the dyed rinsing and decolorizing equipment is rinsing and decolorizing compact fabrics, the water flow cannot penetrate the inside of the fabric, resulting in a decrease in the rinsing and decolorizing rate. At the same time, the rotation direction design of the No. 1 crank and the No. 2 crank can also prevent some impurities and water with too high decolorization concentration from flowing into the side with low concentration, thereby ensuring the rinsing and decolorizing effect of the rinsing and decolorizing equipment based on textile printing and dyeing. It is worth noting that the No. 1 traction roller 402 and the No. 3 traction roller 405 are both rollingly connected to the upper end surface of the fabric, avoiding problems such as fabric wear and uneven tension due to the different rotation radius of the No. 1 crank and the No. 2 crank and the rotation radius of the traction roller.

[0009] Preferably, the cloth is divided into a No. 2 soaking section, a No. 2 spraying section, a No. 1 soaking section and a No. 1 spraying section in sequence from entry to exit on the conveying path in the equipment, the No. 2 soaking section is between the No. 1 tensioning roller and the No. 2 traction roller, the No. 2 spraying section is between the No. 2 tensioning roller and the No. 2 traction roller, the No. 1 soaking section is between the No. 2 tensioning roller and the No. 4 traction roller, and the No. 1 spraying section is between the No. 4 traction roller and the No. 5 traction roller, the No. 1 spraying section and the No. 2 spraying section are both vertically arranged, the No. 1 nozzle is arranged at the top of the No. 1 spraying section, and the cloth is arranged in a vertical state for spraying, thereby avoiding the problem that when the bleaching and decolorizing equipment based on textile printing and dyeing is used to bleach and decolorize the compact cloth, the water flow cannot penetrate the inside of the cloth, resulting in a decrease in the bleaching and decolorization rate, thereby ensuring the bleaching and decolorization effect of the bleaching and decolorizing equipment based on textile printing and dyeing.

[0010] Preferably, a No. 2 drain outlet is provided on the side where the bottom end of the No. 1 washing box is connected to the mounting frame, a No. 2 nozzle is installed on the No. 2 spray section, two of the No. 2 drain outlets are connected to the No. 2 nozzle, the two No. 2 drain outlets are arranged flush with the No. 2 nozzle, and a pressure relief valve is installed at the connection between the two No. 2 drain outlets and the No. 2 nozzle. The No. 2 nozzle installed on the No. 2 spray section avoids the problem that when the rinsing and decolorizing equipment based on textile printing and dyeing is used to rinsing and decolorize compact fabrics, the water flow cannot penetrate the inside of the fabric, resulting in a decrease in the rinsing and decolorization rate. At the same time, the design of the No. 2 drain outlet and the pressure relief valve makes it possible to drive the pressure relief valve to open and spray the fabric only after the water level in the No. 1 washing box reaches the set value. There is no need to install a water pump system separately, which reduces the cost investment of the enterprise and ensures the rinsing and decolorization effect of the rinsing and decolorizing equipment based on textile printing and dyeing.

[0011] Preferably, the No. 1 nozzle and the No. 2 nozzle are respectively installed on both sides of the cloth in the No. 1 spray section and the No. 2 spray section, and multiple rows of nozzles are arranged on the No. 1 nozzle and the No. 2 nozzle. The multiple rows of nozzles are arranged in an array in a high and low manner on both sides of the cloth to avoid problems such as cloth deformation, uneven rinsing and bleaching, and damage to mechanical properties caused by pressure on one side of the cloth. At the same time, the multiple rows of nozzles are installed in a high and low staggered manner to avoid convection of water flow on both sides of the cloth, which leads to a decrease in the rinsing and bleaching rate, thereby ensuring the rinsing and bleaching effect of the rinsing and bleaching equipment based on textile printing and dyeing.

[0012] Preferably, both the No. 1 nozzle and the No. 2 nozzle are equipped with stabilizing plates, and multiple stabilizing plates are respectively located on both sides of the cloth, and a gap of 8-14 cm is provided between the multiple stabilizing plates and the cloth, so that the liquid has more opportunities to contact the cloth, while avoiding the problem that the cloth is swung by the impact of the water flow, resulting in the water flow being unable to flow downward along the cloth, and then resulting in a decrease in the rinsing and decolorization rate, thereby ensuring the rinsing and decolorization effect of the rinsing and decolorization equipment based on textile printing and dyeing.

[0013] Preferably, guide plates are provided on the lower end surfaces of the plurality of stabilizing plates, and the plurality of guide plates are set up in a V-shape on both sides of the cloth. The lower end surfaces of the plurality of guide plates are chamfered to avoid the problem that after the water flow hits the surface of the cloth, it splashes outside the cloth, causing the water flow to be unable to flow downward along the cloth, thereby causing a decrease in the rinsing and decolorization rate, thereby ensuring the rinsing and decolorization effect of the rinsing and decolorization equipment based on textile printing and dyeing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention installs a No. 1 water washing box and a No. 2 water washing box on a mounting frame, and both the No. 1 water washing box and the No. 2 water washing box are equipped with multiple traction rollers and tensioning rollers. A No. 1 nozzle is installed in the No. 1 water washing box, and a No. 1 drain outlet is provided in the No. 2 water washing box. The nozzle sprays clean water onto the surface of the cloth, and a motor drives the multiple traction rollers to rotate and pull the cloth into the No. 2 water washing box and the No. 1 water washing box in sequence for rinsing and decolorizing. This avoids the problem that the rinsing and decolorizing equipment requires a large installation space, increases enterprise costs, and cannot continuously rinse and decolorize the cloth, thereby ensuring the space utilization, production continuity, and applicability of the rinsing and decolorizing equipment based on textile printing and dyeing.

[0016] 2. The present invention has a No. 1 crank and a No. 2 crank rotatably connected to the bottom of the No. 1 washing tank and the No. 2 washing tank respectively, one end of the No. 1 crank and the No. 2 crank are rotatably connected to the mounting frame, the other ends of the No. 1 crank and the No. 2 crank are rotatably connected to the No. 1 traction roller and the No. 3 traction roller respectively, the No. 1 crank is connected to the motor through the No. 2 gear set, and the No. 2 crank is connected to the motor through the No. 3 gear set. This avoids the problem that when the rinsing and decolorizing equipment is rinsing and decolorizing dense fabrics, the water flow cannot penetrate the inside of the fabric, resulting in a decrease in the rinsing and decolorizing rate, thereby ensuring the rinsing and decolorizing effect of the rinsing and decolorizing equipment based on textile printing and dyeing.

[0017] 3. The present invention evenly distributes multiple rows of nozzles on the No. 1 nozzle and the No. 2 nozzle, and the multiple rows of nozzles on the No. 1 nozzle and the No. 2 nozzle are respectively installed on both sides of the cloth in a high-low staggered manner on the No. 1 spray section and the No. 2 spray section, and the No. 1 nozzle and the No. 2 nozzle are respectively installed on both sides of the No. 1 spray section and the No. 2 spray section, thereby avoiding problems such as cloth deformation, uneven rinsing and decolorization, and damage to mechanical properties caused by pressure on one side of the cloth.

DETAILED DESCRIPTION

[0024] See also Figures 1 to 5 The present invention provides a bleaching and decolorizing device based on textile printing and dyeing, and the technical solution is as follows:

[0025] A bleaching and decolorizing device based on textile printing and dyeing, comprising a mounting frame 1, a No. 1 water washing box 201, a No. 2 water washing box 202, a motor 301 and a No. 1 gear set 302, wherein the No. 1 water washing box 201, the No. 2 water washing box 202, the motor 301 and the No. 1 gear set 302 are all mounted on the mounting frame 1, the No. 1 water washing box 201 is mounted on the upper side of the No. 2 water washing box 202, the No. 1 water washing box 201 and the No. 2 water washing box 202 are both equipped with a plurality of traction rollers and a tensioning roller, the No. 1 water washing box 201 is equipped with a No. 1 nozzle 501, the No. 1 water washing box 201 and the No. 2 water washing box 202 are both provided with a No. 1 drain port 203 on one side near the box opening, the motor 301 drives the plurality of traction rollers to rotate simultaneously through the No. 1 gear set 302, and the plurality of traction rollers are used to pull the cloth into the No. 2 water washing box in sequence. The fabric is rinsed and bleached in the No. 1 water washing box 202 and the No. 1 water washing box 201. A plurality of tensioning rollers are used to adjust the tension of the fabric when the traction roller is driven. The No. 1 nozzle 501 is used to spray clean water onto the surface of the fabric. The water level in the No. 1 water washing box 201 rises to the height of the No. 1 drain port 203 and then flows into the No. 2 water washing box 202. The water level in the No. 2 water washing box 202 rises to the height of the No. 1 drain port 203 and then flows out through the No. 1 drain port 203. The folded No. 1 water washing box 201 and No. 2 water washing box 202 avoid the need for a large installation space when the bleaching and bleaching equipment based on textile printing and dyeing is used, which increases the site cost of the enterprise and the problem of being unable to continuously rinse and bleach denim fabrics, thereby ensuring the space utilization, production continuity and applicability of the bleaching and bleaching equipment based on textile printing and dyeing.

[0026] It is worth noting that for thicker and denser denim, such as heavyweight denim over 12 ounces, bleaching and decolorizing equipment based on textile printing and dyeing requires a higher water pressure of 0.3-0.5MPa to allow the detergent to fully penetrate and flush, and effectively remove dyes and impurities; while for thin and low-density denim, such as light denim under 8 ounces, a water pressure of 0.2-0.3MPa can meet the bleaching and decolorization requirements, and excessive water pressure may damage the fabric.

[0027] It is also worth noting that the lateral projections of the No. 1 water washing box 201 and the No. 2 water washing box 202 are V-shaped, the vertical projection of the No. 1 water washing box 201 is located within the vertical projection of the No. 2 water washing box 202, and the No. 1 tensioning roller 401, the No. 1 traction roller 402 and the No. 2 traction roller 403 are installed 20 cm above the highest point of the front end, the lowest point of the middle part and the highest point of the rear end of the No. 2 water washing box 202, respectively. It is equipped with a No. 5 pulling roller 407, a No. 4 pulling roller 406, a No. 3 pulling roller 405 and a No. 2 tensioning roller 404. The cloth is conveyed in sequence through the No. 1 tensioning roller 401, the No. 1 pulling roller 402, the No. 2 pulling roller 403, the No. 2 tensioning roller 404, the No. 3 pulling roller 405, the No. 4 pulling roller 406 and the No. 5 pulling roller 407, thereby avoiding the problem that floating color, residual additives and impurities in the cloth fall back to the surface of the cloth, resulting in a decrease in the bleaching and decolorization rate, and ensuring the bleaching and decolorization effect of the bleaching and decolorization equipment based on textile printing and dyeing.

[0028] See also Figures 2 to 4, the bottom of the No. 1 washing box 201 and the No. 2 washing box 202 are respectively rotatably connected to the No. 1 crank 601 and the No. 2 crank 602, one end of the No. 1 crank 601 and the No. 2 crank 602 are rotatably connected to the mounting frame 1, and the other ends of the No. 1 crank 601 and the No. 2 crank 602 are respectively rotatably connected to the No. 1 traction roller 402 and the No. 3 traction roller 405, and the No. 1 traction roller 402 and the No. 3 traction roller 405 are both rollingly connected to the upper end surface of the cloth, and the No. 2 gear set 603 and the No. 3 gear set 604 are installed on the mounting frame 1, and the No. 2 gear set 603 and the No. 3 gear set 604 are installed on the mounting frame 1, and the No. 1 crank 601 is connected to the motor 301 through the No. 2 gear set 603 and rotates along the S2 direction, and the No. 2 crank 602 is connected to the No. 3 traction roller 405 through the No. 3 gear set 603. The gear set 604 is connected to the motor 301 and rotates in the direction of S3, which avoids the problem that when the rinsing and decolorizing equipment based on textile printing and dyeing is used to rinse and decolorize dense fabrics, the water flow cannot penetrate the inside of the fabric, resulting in a decrease in the rinsing and decolorizing rate. At the same time, the rotation direction design of the No. 1 crank 601 and the No. 2 crank 602 can also prevent some impurities and water with too high decolorization concentration from flowing into the side with low concentration, thereby ensuring the rinsing and decolorizing effect of the rinsing and decolorizing equipment based on textile printing and dyeing. It is worth noting that the No. 1 traction roller 402 and the No. 3 traction roller 405 are both rollingly connected to the upper end surface of the fabric, avoiding problems such as fabric wear and uneven tension due to the different rotation radius of the No. 1 crank 601 and the No. 2 crank 602 and the rotation radius of the traction roller.

[0029] It is worth noting that the cloth is divided into the second soaking section 701, the second spraying section 702, the first soaking section 703 and the first spraying section 704 in the conveying path from entry to exit in the equipment. The second soaking section (701) is between the first tensioning roller 401 and the second traction roller 403, the second spraying section (702) is between the second tensioning roller 404 and the second traction roller 403, the first soaking section (703) is between the second tensioning roller 404 and the fourth traction roller 406, and the fourth traction roller 407 is between the second tensioning roller 404 and the fourth traction roller 408. Between 6 and the fifth traction roller 407 is the No. 1 spray section (704), and the No. 1 spray section 704 and the No. 2 spray section 702 are both vertically arranged. The No. 1 nozzle 501 is arranged at the top of the No. 1 spray section 704, and the cloth is arranged in a vertical state for spraying, thereby avoiding the problem that when the rinsing and decolorizing equipment based on textile printing and dyeing is used to rinsing and decolorize the compact cloth, the water flow cannot penetrate the inside of the cloth, resulting in a decrease in the rinsing and decolorizing rate, thereby ensuring the rinsing and decolorizing effect of the rinsing and decolorizing equipment based on textile printing and dyeing.

[0030] It is also worth noting that a No. 2 drain port 503 is provided on the side where the bottom end of the No. 1 water washing box 201 is connected to the mounting frame 1, and a No. 2 nozzle 502 is installed on the No. 2 spray section 702. The two No. 2 drain ports 503 are connected to the No. 2 nozzle 502, and the two No. 2 drain ports 503 are flush with the No. 2 nozzle 502. A pressure relief valve 504 is installed at the connection between the two No. 2 drain ports 503 and the No. 2 nozzle 502. The No. 2 nozzle 502 installed on the No. 2 spray section 702 avoids The invention solves the problem that when the rinsing and decolorizing equipment based on textile printing and dyeing is used to rinse and decolorize compact fabrics, the water flow cannot penetrate the inside of the fabrics, resulting in a decrease in the rinsing and decolorizing rate. At the same time, the design of the No. 2 drain outlet 503 and the pressure relief valve 504 ensures that the pressure relief valve 504 is driven to open and spray the fabrics only after the water level in the No. 1 washing tank 201 reaches the set value. There is no need to install an additional water pump system, which reduces the company's cost investment and ensures the rinsing and decolorizing effect of the rinsing and decolorizing equipment based on textile printing and dyeing.

[0031] It is also worth noting that the No. 1 nozzle 501 and the No. 2 nozzle 502 are respectively installed on both sides of the cloth in the No. 1 spray section 704 and the No. 2 spray section 702. Multiple rows of nozzles 801 are evenly distributed on the No. 1 nozzle 501 and the No. 2 nozzle 502. The multiple rows of nozzles (801) are arranged in an array in a high and low manner on both sides of the cloth to avoid problems such as cloth deformation, uneven rinsing and bleaching, and damage to mechanical properties caused by pressure on one side of the cloth. At the same time, the multiple rows of nozzles 801 are installed in a high and low staggered manner to avoid convection of water flow on both sides of the cloth, which leads to a decrease in the rinsing and bleaching rate, thereby ensuring the rinsing and bleaching effect of the rinsing and bleaching equipment based on textile printing and dyeing.

[0032] See also Figures 2 to 5 Both the No. 1 nozzle 501 and the No. 2 nozzle 502 are equipped with stabilizing plates 802. Multiple stabilizing plates 802 are located on both sides of the cloth, and a gap of 10 cm is provided between the multiple stabilizing plates 802 and the cloth, thereby preventing the cloth from swinging due to the impact of the water flow, causing the water flow to be unable to flow downward along the cloth, and thus causing the rinsing and decolorization rate to decrease, thereby ensuring the rinsing and decolorization effect of the rinsing and decolorization equipment based on textile printing and dyeing.

[0033] It is worth noting that the lower end surfaces of the multiple stabilizing plates 802 are provided with guide plates 803, and the multiple guide plates 803 are set in a V shape on both sides of the cloth. The lower end surfaces of the multiple guide plates 803 are chamfered to avoid the problem that after the water flow hits the surface of the cloth, it splashes outside the cloth, causing the water flow to be unable to flow downward along the cloth, and then causing a decrease in the rinsing and decolorization rate, thereby ensuring the rinsing and decolorization effect of the rinsing and decolorization equipment based on textile printing and dyeing.

[0034] While working, see Figures 1 to 5, the operator pulls the cloth onto the rinsing and decolorizing equipment based on textile printing and dyeing, and drives the No. 1 gear set 302 through the motor 301 to drive the No. 1 traction roller 402, No. 2 traction roller 403, No. 3 traction roller 405, No. 4 traction roller 406 and No. 5 traction roller 407 to rotate. At this time, the cloth is pulled by the No. 1 traction roller 402, No. 2 traction roller 403, No. 3 traction roller 405, No. 4 traction roller 406 and No. 5 traction roller 407, and enters the No. 2 water washing box 202 and the No. 1 water washing box 201 in turn along the S1 direction for rinsing and decolorization. In this process, the V-shaped No. 1 water washing box 201 and the No. 2 water washing box 202 avoid the problem of floating color, residual additives and impurities in the cloth falling back to the surface of the cloth, resulting in a decrease in the rinsing and decolorization rate. At the same time, when the motor 301 rotates, the No. 2 gear set 603 drives the No. 1 crank 601 Rotating along the S2 direction, the third gear set 604 drives the second crank 602 to rotate along the S3 direction. At this time, the No. 1 traction roller 402 and the No. 3 traction roller 405 will push the cloth to swing, so that the cloth in the No. 1 soaking section 703 and the No. 2 soaking section 701 will swing in the No. 1 washing box 201 and the No. 2 washing box 202, avoiding the problem that when the rinsing and decolorizing equipment based on textile printing and dyeing is used to rinse and decolorize compact cloth, the water flow cannot penetrate the inside of the cloth, resulting in a decrease in the rinsing and decolorization rate. At the same time, the rotation direction design of the No. 1 crank 601 and the No. 2 crank 602 can also prevent some impurities and water with too high decolorization concentration from flowing into the side with low concentration. It is worth noting that when the No. 1 crank 601 and the No. 2 crank 602 drive the cloth to swing, the No. 1 tensioning roller 401 and the No. 2 tensioning roller 404 always tighten the cloth to prevent the cloth from wrinkling.

[0035] Furthermore, when the cloth enters the No. 2 washing box 202 and the No. 1 washing box 201 along the S1 direction for transmission, the No. 1 nozzle 501 sprays water on the cloth in the No. 1 spray section 704 through multiple rows of nozzles 801 in a high and low staggered manner. At this time, the water flow will flush the cloth on the No. 1 spray section 704 and flow downward along the stabilizing plate 802. When the water flow passes through the guide plate 803, the water flow will be guided by the guide plate 803 to flow in the direction of the cloth, so that the water flow flows downward along the cloth and takes away impurities and floating colors on the cloth, thereby improving the rinsing and decolorization effect of the rinsing and decolorization equipment based on textile printing and dyeing.

[0036] Furthermore, the water flows along the fabric in the No. 1 spray section 704 into the No. 1 washing tank 201. When the water level in the No. 1 washing tank 201 reaches the set value, the water pressure in the No. 1 washing tank 201 will push the overflow valve and transmit the water to the No. 2 nozzle 502 through the No. 2 drain port 503. The water is sprayed on the No. 2 spray section 702 through the No. 2 nozzle 502, performing similar work as the No. 1 spray section 704, and then flows along the fabric in the No. 2 spray section 702 into the No. 2 washing tank 202. When the water level in the No. 2 washing tank 202 is flush with the No. 1 drain port 203, the water is discharged out of the No. 2 washing tank 202 through the No. 1 drain port 203. The rinsing and decolorizing equipment based on textile printing and dyeing completes the rinsing and decolorizing work of the fabric through the above process.

[0037] A specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiment described above. For those skilled in the art, various changes, modifications, substitutions, and variations to these embodiments without departing from the principles and ideas of the present invention should still fall within the scope of protection of the present invention.
