Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing and dyeing equipment, in particular to a high-efficiency water-saving printing and dyeing process for fabric and equipment thereof. BACKGROUND

[0002] The textile industry is a traditional pillar industry in China, including textiles, printing and dyeing, chemical fibers, clothing and textile special equipment manufacturing, etc. With the rapid development of the national economy, China's printing and dyeing industry has entered a period of rapid development, and the equipment and technology level has been significantly improved, and the production process and equipment are constantly updated. Printing and dyeing process refers to the physical and chemical treatment of various textile materials in the production process, including the processes of pretreatment, dyeing, printing and finishing of textile materials, collectively known as printing and dyeing process. Dyeing is a process of chemical or physical and chemical combination between dyeing liquid and fiber, or generating pigment on fiber by chemical method, so that the whole textile has a certain firm color. The current printing and dyeing method is mainly to put the fabric into the printing and dyeing pool for immersion dyeing, and then to carry out subsequent steps such as water washing.

[0003] The automatic water-saving printing and dyeing system with publication number CN113174719A includes a printing and dyeing machine, a washing machine and a dyeing liquid recovery unit, which is installed between the printing and dyeing machine and the washing machine. The dyeing liquid recovery unit includes a workbench, a fixed roller, an arc block, a cotton roller, an extrusion block and a recovery chamber. By setting the dyeing liquid recovery unit, the cotton roller absorbs the excess dyeing liquid on the fabric when it contacts the fabric, and the left and right extrusion blocks clamp the cotton roller part, so that the dyeing liquid absorbed by the cotton roller is squeezed out and flows along the surface of the left and right extrusion blocks into the recovery chamber, so that the excess dyeing liquid on the cotton fabric is effectively recovered. When the recovered dyeing liquid in the recovery chamber accumulates more, the operator can extract the dyeing liquid in the recovery chamber through a No. 1 pipe and reuse it to save dyeing liquid.

[0004] Although the above-mentioned printing and dyeing system can absorb the excess dyeing liquid on the fabric and recover the dyeing liquid to save the dyeing liquid, it will intermittently lift the fabric upward when the fabric contacts and absorbs the excess dyeing liquid, which will result in the inability to continuously absorb the excess dyeing liquid on the fabric. In the process of squeezing the liquid from the cotton roller, although part of the dyeing liquid absorbed by the cotton roller can be squeezed out, part of the dyeing liquid will spread and transfer to the upper part of the cotton roller under the extrusion effect, which will increase the dyeing liquid content in the upper part of the cotton roller, thereby reducing the liquid absorption capacity of the part of the cotton roller contacting the fabric and affecting the liquid absorption effect.

[0005] Therefore, it is necessary to invent a high-efficiency water-saving printing and dyeing process for fabric and equipment thereof to solve the above-mentioned problems. SUMMARY

[0006] The present application aims to provide a fabric high-efficiency water-saving printing process and equipment to solve the problems in the background art.

[0047] More specifically, the sliding carriage 305 includes an abutment plate 3051, which is slidingly arranged on the side of the sliding cavity 304 away from the rotating shaft 301, and the abutment plate 3051 is slidingly sealed with the sliding cavity 304; a piston plate 3052, which is fixedly arranged on the side of the abutment plate 3051 close to the rotating shaft 301, and the piston plate 3052 is slidingly sealed in the interior of the sliding cavity 304; a mounting plate 3053, which is fixedly arranged on the side of the abutment plate 3051 away from the rotating shaft 301, and a first liquid suction part 306 is fixedly arranged on the mounting plate 3053, the piston plate 3052 and the side of the sliding cavity 304 away from the rotating shaft 301 form a first cavity, and the space of the first cavity changes with the sliding of the piston plate 3052 in the sliding cavity 304.

[0048] Meanwhile, the liquid suction assembly 3 further includes two circular grooves 308, which are symmetrically arranged on the two side walls of the liquid collecting pool 1, and the two rotating discs 302 are sealingly arranged in the corresponding circular grooves 308; two guide grooves 309, which are symmetrically arranged on the groove bottoms of the corresponding circular grooves 308; two guide rods 310, which are fixedly arranged on the two sides of the mounting plate 3053 and slidingly arranged in the interiors of the corresponding guide grooves 309; the guide grooves 309 can limit the movement track of the guide rods 310, and when the sliding carriage 305 synchronously rotates with the rotating shaft 301, the guide rods 310 are forced to drive the sliding carriage 305 and the first liquid suction part 306 to slide along the sliding cavity 304 due to the guiding effect of the guide grooves 309, and the space of the first cavity changes.

[0049] Furthermore, the liquid suction assembly 3 further includes a first through hole 311, which is arranged on the side of the sliding cavity 304 away from the rotating shaft 301, and the first through hole 311 can be arranged in multiple; a second through hole 312, which is arranged on the side of the mounting plate 3053, and the second through hole 312 can be arranged in multiple; and a driving motor 313, which is fixedly arranged on the outside of the liquid collecting pool 1, and the power output shaft of the driving motor 313 is coaxially fixedly connected with the rotating shaft 301, and the driving motor 313 can drive the rotating shaft 301 to rotate.

[0050] It should be noted that the first liquid suction part 306 and the second liquid suction part 307 are made of the same material, and the first liquid suction part 306 and the second liquid suction part 307 can absorb the excess dye liquid attached to the cloth when in contact with the cloth; the adjacent two second liquid suction parts 307 and the side of the sliding cavity 304 away from the rotating shaft 301 are combined to form a notch 314, the notch 314 can accommodate the corresponding first liquid suction part 306, and when the first liquid suction part 306 is completely accommodated in the corresponding notch 314, the first liquid suction part 306 and the second liquid suction part 307 are kept on the same circular arc surface, the mounting plate 3053 and the notch 314 form a second cavity, and the space of the second cavity changes with the sliding of the mounting plate 3053 in the notch 314, the first through hole 311 communicates the first cavity and the second cavity, and the second through hole 312 communicates the second cavity and the first liquid suction part 306. The cross-sectional area of the second cavity is larger than that of the first cavity.

[0051] The liquid squeezing assembly 4 is arranged in the interior of the liquid collecting pool 1 and can squeeze out the dye liquid in the liquid suction assembly 3; the first liquid suction part 306 and the second liquid suction part 307 can be squeezed by the liquid squeezing assembly 4, so that the dye liquid in the first liquid suction part 306 and the second liquid suction part 307 is squeezed out, thereby ensuring the liquid suction capacity of the first liquid suction part 306 and the second liquid suction part 307.

[0052] Specifically, the liquid squeezing assembly 4 includes two horizontal shafts 401 symmetrically arranged in the interior of the liquid collecting pool 1; two squeezing plates 402 are fixedly arranged on the corresponding horizontal shafts 401; and a coil spring 403 is fixedly arranged between the corresponding horizontal shaft 401 and the side wall of the liquid collecting pool 1. The coil spring 403 provides a torsional force for the horizontal shaft 401, so that the squeezing plate 402 can always be pressed against the first liquid suction part 306 or the second liquid suction part 307, and the arc-shaped structure of the squeezing plate 402 enables the squeezing plate 402 to be pressed against the first liquid suction part 306 or the second liquid suction part 307 in a smooth manner, without scratching the first liquid suction part 306 or the second liquid suction part 307 during the squeezing process.

[0053] The filter screen 5 is fixedly arranged at the bottom of the liquid collecting pool 1, and the liquid collecting pool 1 and the filter screen 5 are both inclined surface structures with high sides and low middle parts. The dye liquid dropped on the liquid collecting pool 1 and the filter screen 5 flows to the middle part of the filter screen 5 along the inclined surface, and then falls into the bottom of the liquid collecting pool 1 after being filtered by the filter screen 5. The filtered fluff gradually accumulates in the middle part of the filter screen 5, and the filtered dye liquid no longer contains impurities such as fluff, which can be directly recycled and reused.

[0054] The cleaning roller 6 is rotatably arranged in the interior of the sump 1 and can clean the lint accumulated in the middle part of the filter screen 5. The cleaning roller 6 is located above the middle part of the filter screen 5. When the cleaning roller 6 rotates, the lint accumulated in the middle part of the filter screen 5 is adhered and collected on the cleaning roller 6. When the first liquid suction part 306 is located directly above the cleaning roller 6, the cleaning roller 6 can be in contact with the first liquid suction part 306, so as to adhere the lint on the first liquid suction part 306.

[0055] The transmission assembly 7 is arranged in transmission between the horizontal shaft 401 and the cleaning roller 6. When the horizontal shaft 401 rotates, the cleaning roller 6 can be driven by the transmission assembly 7 to rotate synchronously, so that the cleaning roller 6 adheres and collects the lint on the filter screen 5.

[0056] Specifically, the transmission assembly 7 includes a transmission cavity 701 arranged on the outside of the sump 1, an internal ratchet wheel 702 fixedly arranged at one end of the cleaning roller 6 and located in the interior of the transmission cavity 701, a dial 703 rotatably arranged in the interior of the transmission cavity 701 and located on the same rotation axis as the internal ratchet wheel 702, the internal ratchet wheel 702 being sleeved on the outside of the dial 703, a mounting groove 704 arranged on the circumferential surface of the dial 703, a pawl 705 rotatably arranged in the mounting groove 704, an elastic member 706 fixedly arranged between the mounting groove 704 and the pawl 705, and a transmission belt 707 arranged in transmission between one of the horizontal shafts 401 and the dial 703. When the horizontal shaft 401 rotates forward, it drives the dial 703 to rotate forward synchronously through the transmission belt 707. At this time, under the clamping action of the pawl 705 and the internal ratchet wheel 702, the dial 703 drives the internal ratchet wheel 702 to rotate synchronously, so that the internal ratchet wheel 702 drives the cleaning roller 6 to rotate, thereby realizing the adhering and collecting of the lint on the filter screen 5. When the horizontal shaft 401 reverses to the initial state, it drives the dial 703 to rotate reversely synchronously through the transmission belt 707. At this time, the pawl 705 rotates in the mounting groove 704, the elastic member 706 is compressed, the pawl 705 no longer clamps with the internal ratchet wheel 702, the dial 703 rotates relatively in the internal ratchet wheel 702, and the internal ratchet wheel 702 is in a stationary state.

[0057] In summary, when the device is used, the dyed cloth is pressed on the liquid suction assembly 3 through the guide roller 2, the driving motor 313 is controlled to rotate, thereby driving the plurality of first liquid suction parts 306 and second liquid suction parts 307 to repeatedly absorb the dye liquid attached to the cloth. Specifically, with the rotation of the liquid suction assembly 3, the first liquid suction parts 306 and the second liquid suction parts 307 sequentially perform the liquid suction operation.

[0058] First, when the liquid suction assembly 3 rotates to the state that the first liquid suction part 306 performs the liquid suction, i.e., as shown in FIG. 2, the first liquid suction part 306 is located above the cleaning roller 6, and the cleaning roller 6 is located above the middle part of the filter screen 5. Figure 12As shown, under the cooperation of the guide groove 309 and the guide rod 310, the first liquid suction part 306 at the top is fully accommodated into the corresponding gap 314 and in contact with the cloth, and the first liquid suction part 306 and the second liquid suction part 307 are kept on the same circular arc surface, the two first liquid suction parts 306 at the two sides force the pressing plate 402 to rotate, the pressing plate 402 is pressed against the two first liquid suction parts 306 under the torsion of the coil spring 403, the two mounting plates 3053 at the two sides are at the openings of the corresponding gaps 314 and separate the corresponding first liquid suction part 306 from the two adjacent second liquid suction parts 307, so that the corresponding first liquid suction part 306 and the two adjacent second liquid suction parts 307 are not in contact with each other, the first liquid suction part 306 at the bottom moves further away from the rotating shaft 301, and finally the mounting plate 3053 at the bottom slides out of the corresponding gap 314, at this time, the mounting plate 3053 at the bottom and the first liquid suction part 306 are not in contact with the two adjacent second liquid suction parts 307, through the above process, the dye liquid in the first liquid suction part 306 at the two sides is squeezed out, the first liquid suction part 306 at the top is in contact with the cloth and absorbs the excess dye attached to the bottom of the cloth.

[0059] It should be noted that the first liquid suction part 306 and the second liquid suction part 307 after being squeezed once by the right pressing plate 402 will be squeezed again when rotating to the left pressing plate 402, so as to realize secondary squeezing of the first liquid suction part 306 and the second liquid suction part 307, thereby ensuring that the first liquid suction part 306 and the second liquid suction part 307 have good liquid suction capacity when sucking liquid.

[0060] By keeping the first liquid suction part 306 and the second liquid suction part 307 at the top on the same circular arc surface, the first liquid suction part 306 will not lift the cloth upward, and the cloth can always closely adhere to the first liquid suction part 306 or the second liquid suction part 307, thereby ensuring the contact area between the first liquid suction part 306 or the second liquid suction part 307 and the cloth, and ensuring the continuity of the liquid suction process of the first liquid suction part 306 or the second liquid suction part 307 in turn, so as to ensure that the cloth can be continuously and comprehensively sucked when passing through the liquid suction assembly 3, and improve the absorption effect of the excess dye liquid on the cloth.

[0061] By separating the corresponding first liquid suction part 306 and the two adjacent second liquid suction parts 307 through the mounting plate 3053 at the two sides, when the pressing plate 402 squeezes the first liquid suction part 306 at the two sides, the dye liquid in the first liquid suction part 306 at the two sides will not spread upward, thereby ensuring the liquid suction capacity of the first liquid suction part 306 and the second liquid suction part 307 above.

[0062] Secondly, when the liquid suction assembly 3 rotates to the state of the second liquid suction part 307 for liquid suction, i.e. as shown in Figure 13 , the pressing plate 402 is used to press the second liquid suction parts 307 on both sides, so as to squeeze the dye liquid in the second liquid suction parts 307 on both sides. The second liquid suction part 307 on the top is in contact with the cloth, and the excess dye attached to the bottom of the cloth is absorbed.

[0063] It should be noted that when the pressing plate 402 is separated from the first liquid suction part 306 and is used to squeeze the second liquid suction part 307, under the torsion of the coil spring 403, the pressing plate 402 will quickly hit the second liquid suction part 307, so as to improve the squeezing effect of the dye liquid in the second liquid suction part 307.

[0064] Meanwhile, during the rotation of the liquid suction assembly 3 from the state as shown in Figure 13 to the state as shown in Figure 12 , due to the cooperation of the guide groove 309 and the guide rod 310, the two first liquid suction parts 306 on the left side, which are about to be used for liquid suction and about to be in contact with the left pressing plate 402, move towards the direction close to the rotating shaft 301. During this process, the space corresponding to the first cavity increases, and the space corresponding to the second cavity decreases. Since the cross-sectional area of the second cavity is larger than that of the first cavity, part of the gas in the second cavity is sucked into the first cavity, and the remaining gas is squeezed and passes through the corresponding first liquid suction part 306 through the first through hole 311 and the second through hole 312. At the same time, the two first liquid suction parts 306 on the right side, which have just completed the liquid suction and have just been separated from the right pressing plate 402, move away from the rotating shaft 301. During this process, the space corresponding to the first cavity decreases, and the space corresponding to the second cavity increases, so that the dye liquid flowing into the first cavity during the liquid suction process is squeezed into the second cavity. When the first liquid suction part 306 rotates to the bottom, the corresponding mounting plate 3053 and the first liquid suction part 306 are not in contact with the adjacent two second liquid suction parts 307, and the gap 314 at the bottom is in an open state. The dye liquid in the corresponding second cavity will directly fall from the gap 314.

[0065] It should be noted that a small amount of dye liquid may be attached to the corresponding first liquid suction part 306 or second liquid suction part 307, which will be subjected to secondary squeezing operation by the left pressing plate 402, so as to keep the first liquid suction part 306 and the second liquid suction part 307 in good liquid suction effect.

[0066] The two first liquid suction parts 306 about to suck liquid and about to contact the left pressing plate 402 move towards the direction close to the rotating shaft 301, so that the gas is pressed and passes through the corresponding first liquid suction part 306, thereby further discharging the dye liquid in the two first liquid suction parts 306, and improving the liquid suction effect of the first liquid suction part 306.

[0067] The two first liquid suction parts 306 just finished sucking liquid and just separated from the right pressing plate 402 move away from the rotating shaft 301, so that the dye liquid flowing into the first cavity during the liquid suction process is pressed into the second cavity, and when the first liquid suction part 306 rotates to the bottom, the gap 314 at the bottom is in an open state, and the dye liquid will directly fall from the gap 314, thereby quickly discharging the dye liquid and improving the discharge speed of the dye liquid.

[0068] The excess dye liquid on the cloth is absorbed by the liquid suction assembly 3, so that the cloth does not carry a large amount of excess dye liquid into the washing pool, the amount of dye liquid flowing into the washing pool is reduced, the replacement frequency of clean water in the washing pool is reduced, thereby avoiding waste of water resources, achieving the purpose of saving water resources, and at the same time, the excess dye liquid is filtered and recycled, achieving the effect of saving dye liquid.

[0069] In the second embodiment, the application also provides a fabric efficient water-saving printing and dyeing process, comprising the following steps:

[0070] Step one, the dyed cloth is sequentially threaded through a plurality of guide rollers 2, so that the cloth is pressed on the top of the liquid suction assembly 3;

[0071] Step two, control the driving motor 313 to rotate, so that the plurality of first liquid suction parts 306 and the second liquid suction parts 307 are sequentially contacted with the bottom of the cloth, thereby absorbing the excess dye liquid attached to the bottom of the cloth;

[0072] Step three, the liquid squeezing assembly 4 sequentially squeezes the plurality of first liquid suction parts 306 and the second liquid suction parts 307, and squeezes out the dye liquid remaining in the first liquid suction parts 306 and the second liquid suction parts 307, thereby ensuring the liquid suction capacity of the first liquid suction parts 306 and the second liquid suction parts 307;

[0073] Step four, the dripping dye liquid is filtered by the filter screen 5 and flows to the bottom of the liquid collecting pool 1 for recycling, and the lint in the dye liquid is collected at the lowest position in the middle of the filter screen 5;

[0074] Step five, the lint collected on the filter screen 5 is adhered and collected by the cleaning roller 6.

[0075] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
