[0040] The water-absorbing sleeve 6 is set to a material with good water absorption, that is, a sponge, whose fiber surface has many pores and can quickly absorb and retain water;

[0041] When the elastic composite fiber cloth 3 is dyed, the cloth 3 is first placed at the bottom of two pressing rollers 4, and the cloth 3 is placed at the top of the guide roller 5 and the water absorption jacket 6;

[0042] Then, dye liquid is placed inside the device body 1, and the water pump 10 is started to extract the dye liquid inside the device body 1 through the first connecting pipe 9 and transfer it to the first water pipe 7, and finally spray it from the first nozzle 8 to the surface of the cloth 3 to dye it;

[0043] When dyeing, the cloth 3 is rolled up from one end close to the water absorption sleeve 6. During the rolling process, the excess dye on the surface of the cloth 3 is absorbed by the water absorption sleeve 6, which can not only ensure the dyeing quality but also reduce the difficulty of subsequent cleaning of the cloth 3.

[0044] like Figures 1 to 8 As shown, the pumping assembly includes a second water pipe 16 arranged inside the water suction roller 11, and the bottom end of the second water pipe 16 is fixedly connected to a water suction pipe 17, and the water suction pipes 17 are evenly arranged.

[0046] like Figure 4 and Figure 5 As shown, a first one-way valve 33 and a second one-way valve 34 are installed on the outer wall of the second connecting pipe 18 .

[0047] When the dye liquid in the water-absorbing jacket 6 is extracted, the dye liquid is made to flow from top to bottom, so as to prevent the dye liquid in the second connecting pipe 18 from flowing back, thereby ensuring the stability and reliability of the dye liquid extraction.

[0048] like Figure 6 and Figure 7 As shown, a filter screen 35 is installed outside the second water pipe 16 .

[0049] When extracting the dye liquid, the impurities in the dye liquid are first filtered through the filter 35, and then extracted and recovered to prevent the dye liquid from being generated or mixed with impurities during the preparation and use process, which may affect the dyeing effect. Filtering it can make the dye liquid purer, thereby improving the uniformity and dyeing effect of dyeing.

[0050] like Figures 1 to 8 As shown, the rotating assembly includes a second bevel gear set 27 arranged at one end of the reciprocating screw 23, the top of the second bevel gear set 27 is fixedly connected to the third rotating shaft 28, the top of the third rotating shaft 28 is fixedly installed with a third bevel gear set 29, one side of the third bevel gear set 29 is fixedly connected to the fourth rotating shaft 30, the end of the fourth rotating shaft 30 away from the third bevel gear set 29 is fixedly installed with a first gear 31, the bottom end of the first gear 31 is meshedly connected with the second gear 32, and the second gear 32 is fixedly installed on the outer wall of the first rotating shaft 15.

[0056] like Figure 6 and Figure 7 As shown, the mounting plate 14 is threadedly connected to the suction roller 11 .

[0057] The mounting plate 14 can be removed by rotating the mounting plate 14, and then the water absorption jacket 6 or the filter screen 35 can be removed for maintenance.

[0058] like Figure 6 and Figure 7 As shown, the water suction jacket 6 is slidably connected to the water suction roller 11 .

A dyeing method for a dyeing device for processing elastic composite fiber fabric, the method being applicable to the dyeing device for processing elastic composite fiber fabric as claimed in claims 1 to 9, characterized in that: The following steps are involved: S1: When the elastic composite fiber cloth (3) is dyed, the cloth (3) is first placed at the bottom of two pressing rollers (4), and the cloth (3) is placed at the top of a guide roller (5) and a water absorbing jacket (6); S2: Then, dye liquid is placed inside the device body (1), and the water pump (10) is started to extract the dye liquid inside the device body (1) through the first connecting pipe (9) and transfer it to the first water pipe (7), and finally spray it from the first nozzle (8) to the surface of the fabric (3) to dye it; S3: When the first connecting tube (9) extracts the dye liquid in the device body (1) for dyeing, the dye liquid in the first connecting tube (9) flows upward to drive the rotating plate (26) to rotate, the rotation of the rotating plate (26) drives the second rotating shaft (25) to rotate, the rotation of the second rotating shaft (25) drives the first bevel gear set (24) to rotate, the rotation of the first bevel gear set (24) drives the reciprocating screw (23) to rotate, and the rotation of the reciprocating screw (23) The movable plate (22) is driven to move back and forth, the movement of the movable plate (22) drives the movement of the piston rod (21), and the movement of the piston rod (21) drives the movement of the piston (20), so that the piston (20) moves back and forth inside the third connecting pipe (19), so that the inside of the second connecting pipe (18) is negatively pressurized, and the dye liquid inside the water absorption sleeve (6) is sucked away through the second water pipe (16) and the water absorption pipe (17), and finally guided back to the device body (1) through the second connecting pipe (18); S4: The rotation of the reciprocating screw (23) drives the rotation of the second bevel gear set (27), the rotation of the second bevel gear set (27) drives the rotation of the third rotating shaft (28), the rotation of the third rotating shaft (28) drives the rotation of the third bevel gear set (29), the rotation of the third bevel gear set (29) drives the rotation of the fourth rotating shaft (30), the rotation of the fourth rotating shaft (30) drives the rotation of the first gear (31), the rotation of the first gear (31) drives the rotation of the second gear (32), the rotation of the second gear (32) drives the rotation of the first rotating shaft (15), the rotation of the first rotating shaft (15) drives the rotation of the fixed plate (13), the rotation of the fixed plate (13) drives the rotation of the water absorption roller (11), the rotation of the water absorption roller (11) drives the rotation of the water absorption jacket (6), so that the water absorption jacket (6) rotates when absorbing dye on the surface of the cloth (3), so that it contacts the surface of the cloth (3) more evenly; S5: After dyeing, the cloth (3) is rolled up from one end close to the water-absorbing sleeve (6). During the rolling process of the cloth (3), the water-absorbing sleeve (6) absorbs excess dye on the surface of the cloth (3).
