Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing equipment, and in particular to a high-efficiency water-saving printing and dyeing process for fabrics and equipment thereof. Background Art

[0002] The textile industry is a traditional pillar industry in my country, including five parts: textile, printing and dyeing, chemical fiber, clothing and textile special equipment manufacturing. With the rapid development of the national economy, my country's printing and dyeing industry has also entered a period of rapid development, with significantly improved equipment and technical levels, and continuous updates of production processes and equipment. Printing and dyeing technology refers to the general term for physical and chemical treatment of various textile materials during the production process, including the pre-treatment, dyeing, printing and finishing of textile materials, collectively referred to as printing and dyeing technology. Dyeing is a process that allows chemical or physical and chemical combination between dye solution and fiber, or generates pigment on fiber by chemical method, so that the entire textile has a certain fast color. The current printing and dyeing method is mainly to put the fabric into the printing and dyeing pool for dyeing, and then carry out subsequent steps such as washing.

[0003] The invention discloses an automated water-saving printing and dyeing system with the publication number CN113174719A, comprising a printing and dyeing machine, a washing machine and a dye recovery unit, wherein the dye recovery unit is installed at a position between the printing and dyeing machine and the washing machine; the dye recovery unit comprises a workbench, a fixed roller, an arc block, a cotton roller, an extrusion block and a recovery chamber; by arranging the dye recovery unit, after the cotton roller absorbs the excess dye on the cloth when in contact with the cloth, the left extrusion block and the right extrusion block play a clamping role on the cotton roller, so that the dye absorbed by the cotton roller is squeezed out and flows into the recovery chamber along the surfaces of the left extrusion block and the right extrusion block, so that the excess dye on the cotton cloth is effectively recovered; when the recovered dye in the recovery chamber accumulates a lot, the operator can extract the dye in the recovery chamber through the No. 1 pipe and reuse it, so as to achieve the purpose of saving dye.

[0004] Although the above-mentioned printing and dyeing system can absorb the excess dye on the cloth and recycle the dye to achieve the purpose of saving dye, it is intermittent when the cloth contacts and absorbs the excess dye, and the cloth cannot be continuously absorbed. In addition, in the process of squeezing the cotton roller, although part of the dye absorbed by the cotton roller can be squeezed out, part of the dye will still spread and transfer to the upper part of the cotton roller under the extrusion effect, resulting in an increase in the dye content in the upper part of the cotton roller, thereby reducing the liquid absorption capacity of the contact part between the cotton roller and the cloth, affecting its liquid absorption effect.

[0005] Therefore, it is necessary to invent a fabric efficient water-saving printing and dyeing process and equipment thereof to solve the above problems. Summary of the invention

[0047] More specifically, the slide 305 includes a connecting plate 3051, which is slidably arranged on the side of the corresponding sliding cavity 304 away from the rotating shaft 301, and a sliding seal is maintained between the connecting plate 3051 and the sliding cavity 304; a piston plate 3052, which is fixedly arranged on the side of the corresponding connecting plate 3051 close to the rotating shaft 301, and the piston plate 3052 is sealingly slidably arranged inside the corresponding sliding cavity 304; a mounting plate 3053, which is fixedly arranged on the side of the corresponding connecting plate 3051 away from the rotating shaft 301, and the 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 constitute a first cavity, and the space of the first cavity changes as the piston plate 3052 slides in the sliding cavity 304.

[0048] At the same time, the liquid suction component 3 also includes a circular groove 308, of which there are two and are symmetrically opened on the two side walls of the liquid collecting pool 1, and the two rotating disks 302 are respectively sealed and rotatably set in the circular groove 308 on the corresponding side; there are two guide grooves 309, which are symmetrically opened at the bottom of the circular groove 308 on the corresponding side; a guide rod 310, which is fixedly set on both sides of the corresponding mounting plate 3053 and slidably set inside the guide groove 309 on the corresponding side; the guide groove 309 can limit the movement trajectory of the guide rod 310, and when the slide 305 rotates synchronously with the rotating shaft 301, due to the guiding effect of the guide groove 309 on the guide rod 310, the guide rod 310 is forced to drive the slide 305 and the first liquid suction part 306 to slide along the sliding cavity 304, and at the same time, the space of the first cavity is changed.

[0049] In addition, the liquid-absorbing component 3 also includes a first through hole 311, which is opened through the side of the sliding cavity 304 away from the rotating shaft 301, and a plurality of first through holes 311 can be provided; a second through hole 312, which is opened through the side of the mounting plate 3053, and a plurality of second through holes 312 can be provided; a driving motor 313, which is fixedly arranged on the outer side 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 absorbing part 306 and the second liquid absorbing part 307 are made of the same material. When the first liquid absorbing part 306 and the second liquid absorbing part 307 are in contact with the cloth, they can absorb the excess dye attached to the cloth in contact with them; the two adjacent second liquid absorbing parts 307 and the side of the sliding cavity 304 away from the rotating shaft 301 are combined to form a notch 314, and the notch 314 can accommodate the corresponding first liquid absorbing part 306. When the first liquid absorbing part 306 is completely accommodated in the corresponding notch 314, the first liquid absorbing part 306 and the second liquid absorbing part 307 are maintained on the same arc surface, and a second cavity is formed between the mounting plate 3053 and the notch 314, and the space of the second cavity changes as the mounting plate 3053 slides in the notch 314, the first through hole 311 connects the first cavity with the second cavity, and the second through hole 312 connects the second cavity with the first liquid absorbing part 306, and the cross-sectional area of ​​the second cavity is larger than that of the first cavity.

[0051] The liquid squeezing component 4 is arranged inside the liquid collecting pool 1, and can squeeze out the dye liquid in the liquid absorbing component 3; the liquid squeezing component 4 can squeeze the first liquid absorbing part 306 and the second liquid absorbing part 307, thereby squeezing out the dye liquid in the first liquid absorbing part 306 and the second liquid absorbing part 307, thereby ensuring the liquid absorbing capacity of the first liquid absorbing part 306 and the second liquid absorbing part 307.

[0052] Specifically, the liquid squeezing component 4 includes two transverse axes 401, which are symmetrically rotated inside the liquid collecting pool 1; two extrusion plates 402, which are respectively fixed on the corresponding transverse axes 401; and a coil spring 403, which is fixed between the corresponding transverse axis 401 and the side wall of the liquid collecting pool 1. The coil spring 403 provides a torsion force for the transverse axis 401, so that the extrusion 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 extrusion plate 402 can make the extrusion plate 402 pressed against the first liquid suction part 306 or the second liquid suction part 307 in a smooth manner, and will not cause scratches to 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 structures with high sides and low middle. The dye dripping on the liquid collecting pool 1 and the filter screen 5 will flow along the inclined surface toward the middle of the filter screen 5, and fall 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 of the filter screen 5. The filtered dye no longer contains impurities such as fluff and can be directly recycled and reused.

[0054] The cleaning roller 6 is rotatably arranged inside the liquid collecting tank 1, and can clean the fluff accumulated in the middle of the filter screen 5. The cleaning roller 6 is located above the middle of the filter screen 5. When the cleaning roller 6 rotates, the fluff accumulated in the middle of the filter screen 5 is adhered and collected on the cleaning roller 6, and when the first liquid absorption part 306 is located directly above the cleaning roller 6, the cleaning roller 6 can contact the first liquid absorption part 306 to adhere to the fluff on the first liquid absorption part 306.

[0055] The transmission assembly 7 is arranged between the horizontal shaft 401 and the cleaning roller 6. When the horizontal shaft 401 rotates, the cleaning roller 6 can be driven to rotate synchronously through the transmission assembly 7, so that the cleaning roller 6 can adhere to and collect the fluff on the filter screen 5.

[0056] Specifically, the transmission assembly 7 includes a transmission chamber 701, which is opened on the outside of the liquid collecting pool 1; an inner ratchet 702, which is fixedly arranged at one end of the cleaning roller 6 and is located inside the transmission chamber 701; a dial 703, which is rotatably arranged inside the transmission chamber 701 and is located on the same rotation axis as the inner ratchet 702, and the inner ratchet 702 is sleeved on the outside of the dial 703; a mounting groove 704, which is opened on the circumferential surface of the dial 703; a pawl 705, which is rotatably arranged in the mounting groove 704; an elastic member 706, which is fixedly arranged between the mounting groove 704 and the pawl 705; a transmission belt 707, which is transmission-arranged between one of the transverse axes 401 and the dial 703; when the transverse axis When 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 inner ratchet 702, the dial 703 will drive the inner ratchet 702 to rotate synchronously, so that the inner ratchet 702 drives the cleaning roller 6 to rotate, thereby realizing the collection of the lint on the filter screen 5. When the horizontal axis 401 is reversed to the initial state, it drives the dial 703 to rotate in the opposite direction synchronously through the transmission belt 707. At this time, the pawl 705 will rotate in the installation groove 704, the elastic member 706 is compressed, the pawl 705 is no longer clamped with the inner ratchet 702, the dial 703 rotates relatively in the inner ratchet 702, and the inner ratchet 702 is in a stationary state.

[0057] In summary, when the device is in use, the printed and dyed cloth is pressed against the liquid absorption component 3 through the guide roller 2, and the driving motor 313 is controlled to rotate, thereby driving multiple first liquid absorption parts 306 and second liquid absorption parts 307 to repeatedly absorb the dye attached to the cloth; specifically, as the liquid absorption component 3 rotates, the first liquid absorption part 306 and the second liquid absorption part 307 perform the liquid absorption operation in turn.

[0058] First, when the liquid absorbing component 3 rotates to the state where the first liquid absorbing part 306 is absorbing liquid, that is, Fig.12As shown, under the cooperation of the guide groove 309 and the guide rod 310, the first liquid suction part 306 located at the top is completely accommodated in the corresponding notch 314 and contacts the fabric, and the first liquid suction part 306 and the second liquid suction part 307 are maintained on the same arc surface, and the two first liquid suction parts 306 located on both sides force the squeezing plate 402 to rotate, and the squeezing plate 402 squeezes the two first liquid suction parts 306 under the torsion of the coil spring 403, and the two mounting plates 3053 located on both sides are located at the opening of the corresponding notch 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 absorbing part 306 will not contact the two adjacent second liquid absorbing parts 307. The first liquid absorbing part 306 at the bottom follows the slide 305 to move further away from the rotating shaft 301, and finally makes the mounting plate 3053 at the bottom slide out of the corresponding notch 314. At this time, the mounting plate 3053 and the first liquid absorbing part 306 at the bottom are not in contact with the two adjacent second liquid absorbing parts 307. Through the above process, the dye in the first liquid absorbing parts 306 at both sides is squeezed out, and the first liquid absorbing part 306 at the top contacts the cloth and absorbs the excess dye attached to the bottom of the cloth.

[0059] It should be noted that after the first liquid absorption part 306 and the second liquid absorption part 307 are squeezed once by the right squeezing plate 402, they will be squeezed again when they are rotated to the left squeezing plate 402, thereby realizing the secondary squeezing of the first liquid absorption part 306 and the second liquid absorption part 307, thereby ensuring that the first liquid absorption part 306 and the second liquid absorption part 307 have good liquid absorption capabilities when absorbing liquid.

[0060] By keeping the first liquid absorbing part 306 and the second liquid absorbing part 307 located at the top on the same arc surface, the first liquid absorbing part 306 will not lift the cloth upward, and the cloth can always be tightly attached to the first liquid absorbing part 306 or the second liquid absorbing part 307, thereby ensuring the contact area between the first liquid absorbing part 306 or the second liquid absorbing part 307 and the cloth, and at the same time ensuring the continuity of the liquid absorbing process performed by the first liquid absorbing part 306 or the second liquid absorbing part 307 in sequence, ensuring that the cloth can be continuously and comprehensively absorbed when passing through the liquid absorbing component 3, thereby improving the absorption effect of excess dye on the cloth.

[0061] The corresponding first liquid absorption part 306 is separated from the two adjacent second liquid absorption parts 307 by the mounting plates 3053 located on both sides, so that when the squeezing plate 402 squeezes the first liquid absorption parts 306 located on both sides, the dye liquid in the first liquid absorption parts 306 on both sides will not spread upward, thereby ensuring the liquid absorption capacity of the first liquid absorption part 306 and the second liquid absorption part 307 located above.

[0062] Secondly, when the liquid absorbing component 3 rotates to the state where the second liquid absorbing part 307 is absorbing liquid, that is, Fig.13 As shown, at this time, the squeezing plate 402 squeezes the second liquid absorbing parts 307 located on both sides, thereby squeezing out the dye in the second liquid absorbing parts 307 located on both sides, and the second liquid absorbing part 307 located on the top contacts the cloth to absorb the excess dye attached to the bottom of the cloth.

[0063] It should be noted that when the squeezing plate 402 detaches from the first liquid absorbing part 306 and squeezes liquid from the second liquid absorbing part 307 , the squeezing plate 402 will quickly hit the second liquid absorbing part 307 under the torsion of the coil spring 403 , thereby improving the squeezing effect of the dye in the second liquid absorbing part 307 .

[0064] At the same time, in the liquid suction component 3 from Fig.13 The status shown is as follows Fig.12 During the rotation in the state shown, due to the cooperation of the guide groove 309 and the guide rod 310, the two first liquid suction parts 306 located on the left side that are about to absorb liquid and are about to contact the left extrusion plate 402 move towards the direction close to the rotation shaft 301. During this process, the space corresponding to the first cavity increases, and the space of 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 will be squeezed through the first through hole 311 and the second through hole 312 and pass through the corresponding first liquid suction part 306; at the same time, The two first liquid absorbing parts 306 on the right side that have just completed liquid absorption and just separated from the right squeezing plate 402 both move in the direction away from the rotating shaft 301. During this process, the space of the corresponding first cavity is reduced, and the space of the second cavity is increased, so that the dye liquid flowing into the first cavity during the liquid absorption process is squeezed into the second cavity. When the first liquid absorbing part 306 rotates to the bottom, the corresponding mounting plate 3053 and the first liquid absorbing part 306 are not in contact with the two adjacent second liquid absorbing parts 307, and the notch 314 at the bottom is in an open state, and the dye liquid in the corresponding second cavity will directly scatter from the notch 314.

[0065] It should be noted that a small amount of the rapidly discharged dye liquid will be contaminated onto the corresponding first liquid absorption part 306 or the second liquid absorption part 307, and the first liquid absorption part 306 and the second liquid absorption part 307 will then undergo a secondary liquid squeezing operation on the left squeezing plate 402 to ensure that the first liquid absorption part 306 and the second liquid absorption part 307 maintain a good liquid absorption effect.

[0066] By moving the two first liquid absorbing parts 306 that are about to absorb liquid and are about to contact the left extrusion plate 402 toward the direction close to the rotating shaft 301, the gas is squeezed and passes through the corresponding first liquid absorbing parts 306, thereby further discharging the dye liquid in the two first liquid absorbing parts 306, thereby improving the liquid absorption effect of the first liquid absorbing parts 306.

[0067] The two first liquid absorbing parts 306 that have just completed the liquid absorption and just separated from the right squeezing plate 402 move in the direction away from the rotating shaft 301, so that the dye liquid flowing into the first cavity during the liquid absorption process is squeezed into the second cavity, and when the first liquid absorbing part 306 rotates to the bottom, the notch 314 at the bottom is in an open state, and the dye liquid will be scattered directly from the notch 314, so that the dye liquid is quickly discharged, thereby improving the discharge speed of the dye liquid.

[0068] The excess dye on the cloth is absorbed by the liquid absorption component 3, so that the cloth will not carry a large amount of excess dye into the washing tank, reducing the amount of dye flowing into the washing tank, thereby reducing the frequency of replacing the clean water in the washing tank, thereby avoiding the waste of water resources and achieving the purpose of saving water resources. At the same time, the excess dye is recycled and reused after filtering, achieving the effect of saving dye.

[0069] Embodiment 2, the present invention also provides a fabric efficient water-saving printing and dyeing process, comprising the following steps:

[0070] Step 1: Pass the dyed fabric through a plurality of guide rollers 2 in sequence, so that the fabric is pressed tightly against the top of the liquid absorbing component 3;

[0071] Step 2: Control the driving motor 313 to rotate so that the first liquid absorbing parts 306 and the second liquid absorbing parts 307 contact the bottom of the cloth in sequence, so as to absorb the excess dye attached to the bottom of the cloth;

[0072] Step 3: The liquid squeezing component 4 sequentially squeezes the first liquid absorbing parts 306 and the second liquid absorbing parts 307 to squeeze out the dye liquid retained in the first liquid absorbing parts 306 and the second liquid absorbing parts 307, so as to ensure the liquid absorbing capacity of the first liquid absorbing parts 306 and the second liquid absorbing parts 307;

[0073] Step 4: The dripping dye liquid is filtered through the filter screen 5 and flows to the bottom of the liquid collecting tank 1 for recycling, and the fluff in the dye liquid is collected at the lowest position in the middle of the filter screen 5;

[0074] Step 5: The cleaning roller 6 collects the fluff collected on the filter screen 5 by adhesion.

[0075] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
