[0022] This utility model discloses a low-water dyeing and printing device, comprising a dyeing and printing machine body 101, a support frame 102, a drying box 103, a collection tank 104, a guide roller 105, a first scraper 106, a second scraper 107, a conveying pipe 108, a sliding sleeve 109, a guide rod 110, an adjusting rod 111, a mounting plate 112, a fixing frame 113, an adjusting nut 114, a locking nut 115, a first sealing ring 116, a second sealing ring 117, and a filter screen 118. It solves the problem that while existing technologies can smooth and dry dyed fabrics, they cannot recover and reuse excess dye from the fabric during the process, leading to significant waste of dye liquor and increased costs. It is understood that the aforementioned solution can also be used to reduce dye liquor consumption and lower dyeing and printing costs.

[0023] In this embodiment, the dyeing machine body 101, the support frame 102, and the drying box 103 are all existing technologies. The specific structure refers to the existing technology CN207987507U, a low-water dyeing device. Through the recycling component, the problem of existing technologies being unable to recycle and reuse excess dye on the fabric during the process, which leads to serious waste of dye liquor and increased costs, is solved.

[0024] The collecting trough 104 is fixedly connected to the support frame 102 and located between the dyeing machine body 101 and the drying chamber 103. The guide roller 105 is fixedly connected to the collecting trough 104 and located inside the collecting trough 104. The first scraper 106 is fixedly connected to the guide roller 105 and located on the periphery of the guide roller 105.

The support member is used to support the second scraper 107 and facilitates the adjustment of the distance between the second scraper 107 and the first scraper 106. After the fabric is dyed by the dyeing machine body 101, it passes through the gap between the first scraper 106 and the second scraper 107, which makes the fabric squeezed, thereby scraping the excess dye into the collection tank 104. The two ends of the conveying pipe 108 are respectively connected to the bottom of the collection tank 104 and the dye pool inside the dyeing machine body 101. Next, the collection tank 104 is positioned higher than the dyeing machine body 101. The dye scraped onto the collection tank 104 will automatically flow back into the dye pool inside the dyeing machine body 101 through the conveying pipe 108 under the action of gravity. Through the cooperation of the first scraper 106 and the second scraper 107, excess dye on the fabric can be scraped onto the collection tank 104 for recycling. This solves the problem that although the existing technology can flatten and dry the dyed fabric, it cannot recycle excess dye on the fabric during the process, resulting in serious waste of dye liquor and increased costs.

Tightening the adjusting nut 114 and the locking nut 115 to make them abut against the fixing frame 113 fixes the adjusting rod 111. Tightening the adjusting nut 114 and the locking nut 115 allows for the adjustment of the adjusting rod 111.

[0027] In addition, the first sealing ring 116 is disposed on the collection groove 104 and located between the collection groove 104 and the adjusting rod 111; the second sealing ring 117 is disposed inside the sliding sleeve 109 and located between the sliding sleeve 109 and the guide rod 110. The first sealing ring 116 is embedded at the connection between the collection groove 104 and the adjusting rod 111, and can fill the gap between the collection groove 104 and the adjusting rod 111. The sealing ring is embedded on the inner wall of the sliding sleeve 109, and can fill the gap between the sliding sleeve 109 and the guide rod 110.

At the same time, it has high strength, good durability, and long service life. The filter screen 118 can be used to filter the dye liquor.

[0029] In this embodiment, during use, the fabric is dyed through the dyeing machine body 101, then enters the collection tank 104, bypasses the guide roller 105, and enters the drying chamber 103 for drying. During this process, the fabric passes through the gap between the first scraper 106 and the second scraper 107. Under the pressure of the first scraper 106 and the second scraper 107, excess dye is scraped and left in the collection tank 104. After being filtered by the filter screen 118, it flows back to the dye pool inside the dyeing machine body 101 through the conveying pipe 108, realizing the recycling of dye. In addition, The gap between the second scraper 107 and the first scraper 106 can be adjusted to accommodate dyes of different thicknesses. During adjustment, first loosen the adjusting nut 114 and the locking nut 115. At this time, the adjusting rod 111 is in the unlocked state and can be moved. After moving the second scraper 107 to an appropriate position according to the actual situation, first tighten the adjusting nut 114 to make it abut against the fixing frame 113. Then, tighten the locking nut 115 to make it abut against the fixing frame 113. At this time, the position of the adjusting rod 111 is fixed, thus positioning the second scraper 107. This application, through the cooperation of the first scraper 106 and the second scraper 107, can scrape excess dye from the fabric into the collection tank 104 for recycling. This solves the problem that although existing technologies can smooth and dry dyed fabrics, they cannot recycle excess dye during the process, leading to serious waste of dye liquor and increased costs.
