[0038] A plurality of third sealing bearings are embedded and mounted on one side of the dyeing box 100, the inner edge of the third sealing bearing is fixedly connected with the surface of the round pipe 340, thereby sealing the connection between the round pipe 340 and the dyeing box 100.

[0039] The working principle is that when the knitted fabric is dyed, the fabric is arranged along the plurality of limiting rollers 200, and the two ends of the knitted fabric are fixed through the fixed plates on the two limiting rollers 200 above, so that the knitted fabric is soaked in the dye in the dyeing box 100 for dyeing. At the same time, the controller starts the water pump 320 to pump out the dye solution from the bottom of the dyeing box 100, and the pumped-out dye solution enters the three circular pipes 340 at the same time through the connecting pipe 330, and is discharged into different positions in the dyeing box 100 through the plurality of liquid outlet pipes 350 on the circular pipes 340. At the same time, the controller starts the motor 311 to drive the sieve plate 360 to reciprocate to increase the flowability of the dye solution at the bottom of the dyeing box 100. At the same time, the sieve plate 360 will drive the two circular rods 372 to reciprocate up and down under the action of the spring 371 and the mounting plate 361, so as to increase the flowability of the dye solution on both sides of the dyeing box 100. At the same time, the motor 311 will drive the lead screw 314 to rotate forward and backward under the action of the large bevel gear 312 and the small bevel gear 313, so as to drive the moving rod 315 to reciprocate up and down, and drive the plurality of first gears 317 to drive the corresponding circular pipes 340 to reciprocate. The circular pipes 340 will change the direction of the opening of the liquid outlet pipe 350 during rotation, and the liquid outlet pipe 350 will drive the corresponding baffle plate 352 to rotate synchronously. The baffle plate 352 will disperse the dye solution introduced from the liquid outlet pipe 350 and mix with the dye solution in the dyeing box 100 during reciprocating rotation, so as to make the dye concentration in the dyeing box 100 uniform.

[0040] It should be noted that the motors, water pumps and the like in the above description are relatively mature devices in the prior art, and the specific models can be selected according to actual needs. At the same time, the power supply of the motor and the water pump can be built-in power supply or mains power supply, and the specific power supply mode is selected as the case requires, which will not be described here.

[0041] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
