The dyeing process applying the cold batch dyeing machine comprises the following steps:

step s 100: the cloth is unwound and input into the dip-dyeing box 21, the cloth passes through two adjacent rollers 23 after bypassing the dip-dyeing roller 22 to extrude the cloth, then the cloth bypasses the cloth outlet roller 241 and is wound on the driving roller 32 to be wound, the cloth outlet roller 241 presses the driving roller 32 under the pushing of the air cylinder 261 to drive the driving roller 32 to rotate, the pressure sensor 263 detects the pressure value of the sliding block 262 so as to detect the pressure value between the cloth outlet roller 241 and the cloth, and the controller 264 controls the air cylinder 261 to stretch and retract so as to keep the pressure borne by the cloth consistent.

Step s 200: the nut 342 is rotated to unlock the collar 34, the collar 34 is slid to make the flexible film 33 gradually cover the surface of the cloth, and then the magnetic conductive sheet 52 and the magnetic ring 51 are mutually adsorbed to isolate the cloth from the outside.

Step s 300: the frame 31 is transferred to one side of the driving motor 41, the locking pipe 42 is in inserting fit with the inserting groove 321, the clutch ring 43 is slid to enable the clutch bolt 422 to be in inserting fit with the clutch groove 322, and the clutch ring 43 is rotated to realize the relative fixation of the output shaft of the driving motor 41 and the driving roller 32.

Step s 400: and (3) starting the driving motor 41, driving the cloth to rotate at a constant speed by the driving roller 32 so as to enable the dye liquor to uniformly permeate into the cloth fibers under the action of self gravity, keeping the driving roller 32 in a rotating state for at least 24 hours, and then unfastening the flexible film 33 to take down the cloth to complete the cloth dyeing process.

The implementation principle of the embodiment is as follows: the staff only need open transmission motor 112 and rotate with drive transmission roller 111, and the cloth is walked around transmission roller 111 and is transmitted, and the cloth contacts the dye liquor in the dip-dye box 21 when walking around dip-dye roller 22 to this adsorbs the dye liquor and makes things convenient for the fixation in later stage. The roller 23 extrudes the dip-dyed cloth to remove redundant dye liquor on the cloth, so that the dye liquor dripping in the cloth transportation process is reduced, and the utilization rate of the dye liquor is improved. And the support arm 24 drives the cloth outlet roller 241 to abut against the peripheral side wall of the driving roller 32, the support arm 24 and the cloth outlet roller 241 press the cloth on the driving roller 32 under the action of self gravity, the air cylinder 261 presses the support arm 24, and the cloth outlet motor 251 drives the cloth outlet roller 241 to rotate and drives the driving roller 32 to rotate through the friction force between the cloth outlet roller 241 and the driving roller 32, so that the cloth is wound on the driving roller 32.

The staff spreads the flexible membrane 33 in order to cover the cloth surface, and magnetic ring 51 and magnetic conduction piece 52 attract each other in order to close flexible membrane 33, isolated cloth and external, reduce the loss of dye liquor to improve the quality of cloth dyeing. The cloth is transferred through the frame 31, one end of the driving roller 32 is opposite to the driving motor 41, then the locking pipe 42 is in plugging fit with the plugging groove 321 to connect the output shaft of the driving motor 41 and the driving roller 32, and the clutch ring 43 drives the driving block 432 to slide when sliding along the axial direction of the output shaft of the driving motor 41. The clutch bolt 422 contacts with the driving block 432 and slides along the radial direction of the output shaft of the driving motor 41 under the guidance of the inclined surface of the driving block 432 and protrudes out of the outer wall of the locking pipe 42, so as to be in insertion fit with the clutch groove 322, thereby fixing the output shaft of the driving motor 41 and the driving roller 32.

The driving roller 32 drives the cloth wound thereon to rotate, so that the residual dye liquor in the cloth repeatedly permeates the fibers in the cloth under the action of the gravity of the dye liquor, the fibers of the cloth are uniformly fixed, and the color fastness of the cloth is improved. The flexible film 33 sleeved on the cloth isolates the cloth from the outside, reduces the loss of the dye liquor, enables the dye liquor to be fully contacted with the cloth, and simultaneously reduces the contact of the cloth and dust, thereby improving the effect of cold batch dyeing, improving the utilization rate of the dye liquor and realizing the effect of water conservation.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
