[0022] The outer wall of the overflow tank 6 is connected to a circulation box through a pipeline, one end of the circulation box is connected to the bottom of the mixer 3, one end of the liquid pump 4 is connected to the inner wall of the overflow pipe 5 through a pipeline, and the connection between the overflow pipe 5 and the liquid pump 4 is rotatably connected through a rotating shaft.

[0023] In this embodiment: through this structure, the dye liquid in the mixer 3 can be transported to the overflow pipe 5 through the pipeline under the action of the liquid pump 4, and the dye liquid can be sprayed out through the overflow pipe 5 to dye the cloth. In this process, by starting the drive motor 701, the drive motor 701 will drive the first bevel gear 702 at the output end to rotate, and the rotating first bevel gear 702 gives the first spur gear 703 engaged with the outer wall a rotational thrust. The stressed first spur gear 703 synchronously drives the overflow pipe 5 with a fixed axis to rotate. When the outer wall tooth block of the first bevel gear 702 is no longer in contact with the first spur gear 703, the overflow pipe 5 will be reset under the action of gravity. During the reset process, the overflow pipe 5 will swing, and the swinging overflow pipe 5 will The dye liquid is driven to move step by step, the contact time and area of ​​the dye liquid and the cloth are increased, and the dye liquid efficiency is improved. When the first bevel gear 702 rotates, the second bevel gear 706 is also driven to rotate synchronously, so that one end of the second transmission rod 707 eccentrically connected to the outer wall of the second bevel gear 706 will also move synchronously in a circumferential direction, and then the transmission wheel 708 eccentrically connected to the other end of the second transmission rod 707 will also rotate in a circumferential direction, and the guide box 709 fixedly connected to the shaft of the transmission wheel 708 will also swing, so that the cloths are overlapped and piled up after falling, which is convenient for the cloths to further contact with the dye liquid, thereby improving the utilization rate of the dye liquid. The overflowing dye liquid will enter the bottom of the liquid pump 4 again through the circulation box on the outer wall of the overflow trough 6, thereby completing the recycling of the dye liquid.

[0024] After the fabric dyeing liquid is completed, the inside of the overflow tank 6 needs to be cleaned, and the pull rod 901 is given a rotational force to make the limit block 903 fixed on the outer wall of the pull rod 901 rotate synchronously and move to the angular position of the wire groove inside the fixed seat 902, and then the pull rod 901 is given a thrust, so that the pull rod 901 synchronously pushes the third bevel gear 804 to contact and mesh with the outer walls of the second spur gear 803 and the fourth bevel gear 805, and then the drive motor 701 is started again.

The rotating fourth bevel gear 805 synchronously drives the bidirectional screw rod 806 to rotate. Then, the cleaning rod 807 sleeved on the outer wall of the bidirectional screw rod 806 will be subjected to the rotational thrust from the bidirectional screw rod 806 and move axially along the inner side of the overflow trough 6 to clean the inner side of the overflow trough 6, thereby preventing the dye liquid from remaining on the inner side of the overflow trough 6 and affecting the subsequent fabric dyeing, thereby improving product quality.

[0025] Please refer to Figure 1-Figure 6 The inner wall of the fixing seat 902 is formed with a limiting groove for the limiting block 903 to move, and the cross section of the limiting groove is a "C"-shaped structure.

[0026] In this embodiment: this structure can limit the position of the pull rod 901 in cooperation with the limit block 903 under the action of the "C"-shaped limit groove on the inner side of the fixed seat 902, thereby positioning the position of the third bevel gear 804 rotatably connected to the end.

[0027] Please refer to Figure 1-Figure 6 The inner wall of the cleaning rod 807 is formed with a thread groove matching the outer wall of the bidirectional screw rod 806, and a brush for cleaning the dye solution is installed at the bottom of the cleaning rod 807. The outer wall of the first bevel gear 702 is respectively provided with tooth blocks meshing with the outer walls of the first spur gear 703 and the second bevel gear 706. The tooth blocks on the outer wall of the first bevel gear 702 are distributed 180 degrees on the outer wall of the first bevel gear 702, and the outer wall of the third bevel gear 804 is vertical to the outer wall of the fourth bevel gear 805, and the third bevel gear 804 is meshed with the outer wall of the fourth bevel gear 805.

[0028] In this embodiment: through this structure, a first spur gear 703 can be driven to rotate synchronously with the rotation of the first bevel gear 702. When the first spur gear 703 rotates, the first transmission rod 704 eccentrically connected to the outer wall will also synchronously drive multiple rotating wheels 705 to rotate, and multiple overflow pipes 5 fixed to the axis of the first spur gear 703 and the rotating wheel 705 will also swing accordingly until the first bevel gear 702 is no longer in contact with the first spur gear 703, and the multiple overflow pipes 5 will also be reset under the action of gravity and self-weight until the next time the first spur gear 703 and the first bevel gear 702 contact.
