[0025] like Figure 1-Figure 2 As shown, a dyeing and printing liquid mill pre-treatment device includes a liquid storage tank 1, and the front and rear ends of the liquid storage tank 1 are respectively provided with an inlet 2 and an outlet 3, including:

[0026] There are four rollers 4, which are connected to the liquid storage tank 1 in pairs and rotate symmetrically up and down. When the grey cloth passes through and hits the rollers 4, the cross section of the grey cloth is in a basin shape;

[0027] A pump body 5 is installed inside the liquid storage tank 1. A water spray pipe 6 is connected to the water outlet of the pump body 5, and the bottom of the water spray pipe 6 faces the grey cloth. A water suction pipe 7 is connected to the water inlet of the pump body 5, and the bottom of the water suction pipe 7 faces the grey cloth.

[0028] A liquid filling port 8 is provided at the top of the liquid storage tank 1, is communicated with the liquid storage tank 1, and is located above the inlet of the liquid storage tank 1;

[0029] The liquid outlet 9 is arranged at the bottom of the liquid storage tank 1 , is communicated with the liquid storage tank 1 , and is located below the outlet 3 of the liquid storage tank 1 .

[0030] In this embodiment, the printing and dyeing liquid rolling machine printing and dyeing pre-treatment equipment, as a key component in the textile printing and dyeing process, integrates efficient and stable liquid treatment and grey cloth pre-treatment functions, which not only optimizes liquid circulation and penetration efficiency, but also ensures uniform liquid reception and efficient cleaning of the grey cloth during the treatment process. The grey cloth passing through the roller 4 has a basin-shaped cross-section in the liquid storage tank 1, and is driven by a water pump, and the water suction pipe 7 generates suction on the grey cloth, so that the liquid in the liquid storage tank 1 passes through the grey cloth, and then the alkaline solution penetrates the grey cloth through the water spray pipe 6 from the output end of the water pump, achieving high penetration and high efficiency. Both sides of the grey cloth are soaked in alkaline solution, which can be more continuously and stably pre-treated on the grey cloth compared to the comparative document.

[0031] As a key component for driving liquid circulation, the pump body 5 is cleverly installed inside the liquid storage tank 1. Its water outlet is closely connected to the water spray pipe 6, and the bottom of the pipe is directly aimed at the grey cloth, ensuring that the alkaline solution can be accurately and efficiently sprayed onto the surface of the grey cloth and penetrate into the fiber. At the same time, the water inlet of the pump body 5 is connected to the bottom of the liquid storage tank 1 through the water suction pipe 7 to form a circulation loop. This design not only improves the utilization efficiency of the liquid, but also enhances the treatment effect.

[0032] As an optional embodiment, a partition 10 for sealing the pump body 5 is provided on the outside of the pump body 5, and the partition 10 is fixedly connected to the inner wall of the liquid storage tank 1. Two holes are reserved on the partition 10 for the water spray pipe 6 and the water suction pipe 7 to pass through.

[0033] Thus, in order to further improve the sealing performance and maintenance convenience of the equipment, a partition 10 is added to the bottom of the pump body 5, and the partition 10 is fixedly connected to the inner wall of the liquid storage tank 1, and a hole is reserved for the water spray pipe 6 and the water suction pipe 7 to pass through. This design effectively avoids the corrosion or leakage problems that may be caused by the direct contact between the pump body 5 and the bottom of the liquid storage tank 1.

[0034] As an optional implementation, Figure 1 As shown, the bottom of the water suction pipe 7 is connected to a three-way joint 11, and the two sides of the three-way joint 11 are respectively connected to a first water pipe 12 and a second water pipe 13, the first water pipe 12 is located in front of the second water pipe 13, the end of the first water pipe 12 and the end of the water spray pipe 6 are located at the same horizontal height, and the second water pipe 13 is inclined upward toward the rear end of the grey cloth;

[0035] In this way, the rear end of the grey cloth after post-treatment is not immersed in the alkaline solution, and a three-way joint 11 is introduced into the bottom of the water absorption pipe 7, which is connected to the first water pipe 12 and the second water pipe 13 respectively. The former is used to assist the water spray pipe 6 to realize the liquid spraying function; the latter is uniquely designed to be inclined upward toward the rear end of the grey cloth to absorb the alkaline solution remaining on the grey cloth after the pre-treatment is completed. This innovative design significantly reduces the mechanical damage to the grey cloth and improves the cleaning effect.

[0036] As an optional implementation, Figure 1 As shown, the end of the water spray pipe 6 is connected to a water spray plate 14, and the ends of the first water pipe 12 and the second water pipe 13 are respectively fixedly connected and connected to a first water absorption plate 15 and a second water absorption plate 20, and the water spray plate 14, the first water absorption plate 15, and the second water absorption plate 20 are all in contact with the grey cloth;

[0037] In this way, the water spray plate 14 and the water absorption plate 15 are used as the contact medium between the pipeline and the grey cloth, further optimizing the interaction interface between the liquid and the grey cloth, and ensuring the uniformity of liquid distribution and the depth of penetration.

[0038] As an optional implementation, Figure 1 As shown, an electric heating plate 16 is provided inside the bottom of the water storage tank;

[0039] In this way, the electric heating plate 16 built into the bottom of the liquid storage tank 1 can adjust the temperature of the alkaline solution in the tank as needed to promote the increase of the chemical reaction rate and the stability of the process.

[0040] As an optional implementation, Figure 1 , 2 As shown, a filter 17 is installed in the water suction pipe 7;

[0041] In this way, the filter 17 provided in the water suction pipe 7 effectively intercepts impurities and particulate matter in the liquid, thereby ensuring the purity of the treated liquid and the long-term stable operation of the equipment.

[0042] As an optional embodiment, the liquid level of the alkaline aqueous solution in the water storage tank is located between the lowest point of the second water absorption tray 20 and the upper surface of the grey cloth;

[0043] In this way, it is ensured that the second water pipe 13 absorbs the alkaline solution in the grey cloth instead of the solution in the liquid storage tank 1, thereby ensuring the best liquid absorption effect.

[0044] As an optional implementation, Figure 1 As shown, a water temperature sensor 18 is provided at one end of the inner side of the liquid storage tank 1, and a water level sensor 19 is provided at the other end of the inner side of the liquid storage tank 1;

[0045] In this way, the water temperature and water level in the liquid storage tank 1 are monitored, and heating or adding of solution is done in time when necessary, so as to maintain the continuous working stability of the equipment.
