[0023] The suspension frame 304 consists of a vertical rod, a curved connecting rod, and hooks. Eight hooks are symmetrically welded evenly on the vertical rod of the suspension frame 304, and the middle and lower parts of the vertical rod are reinforced by welding the curved connecting rods.

[0024] Specifically, the fan-shaped cover 301 seals the upper end of the fan-shaped frame 2 to prevent dye liquid from overflowing; the sealing gasket 302 fits into the groove of the fan-shaped cover to enhance the sealing performance; the handle 303 facilitates the handling of the suspension frame 304, which is conducive to other equipment hooking onto the lifting wire placement frame 3; the vertical rod of the suspension frame 304 is welded with hooks, and the middle and lower ends are reinforced by bending connecting rods to ensure the stability of the wire suspension.

[0025] See appendix Figure 1-6 As shown, the stirring mechanism 5 includes a geared motor 501 installed in the central groove at the upper end of the tank body 1; a stirring rod 502 driven to rotate by the lower end of the rotating shaft of the geared motor 501 for stirring the inside of the tank body 1; and a limiting rod 503 welded to the lower end of the tank body 1, with the lower end of the stirring rod 502 inserted into the limiting rod 503 to stabilize the lower end of the stirring rod 502.

[0026] The stirring rod 502 is evenly welded with multiple stirring blades for stirring the dye inside the tank 1.

[0027] Specifically, the geared motor 501 provides power, which drives the stirring rod 502 to rotate at low speed after deceleration. It is fixed in the central groove at the upper end of the tank body 1, and the output shaft is vertically connected to the stirring rod 502. The stirring rod 502 drives the stirring blades to rotate, promotes the flow of dye liquor, and ensures uniform dyeing of the filaments. Multiple stirring blades are welded to the surface of the rod body, and the lower end is inserted into the limiting rod 503 to stabilize the rotation. The limiting rod 503 fixes the lower end of the stirring rod 502 to prevent swaying or eccentricity during high-speed rotation. It is welded to the bottom of the tank body 1, and the internal through hole is clearance-fitted with the lower end of the stirring rod.

[0028] See appendix Figure 1-7 As shown, the rinsing mechanism 6 includes a fixed frame 601 welded to the upper end of the tank body 1; a water pump 602 welded inside the fixed frame 601 for pumping water; and an annular spray pipe 603 welded inside the upper end of the tank body 1. The water inlet of the annular spray pipe 603 is fixedly connected to the water outlet of the water pump 602, and the water pump 602 fills the annular spray pipe 603 with water.

[0029] The annular spray pipe 603 has welded nozzles evenly distributed on its surface facing downwards. The nozzles are connected to the inside of the annular spray pipe 603 and are used to spray and rinse the dye inside the tank 1.

[0030] Specifically, the fixed frame 601 supports the water pump 602 and is fixed to the upper end of the tank 1. The frame is welded to ensure that the water pump is installed firmly. The water pump 602 draws water and delivers it to the annular spray pipe 603 to provide rinsing power. It is started by the control box 11 to rinse the residual dye inside the tank after dyeing. The annular spray pipe 603 surrounds the upper end of the inside of the tank 1 and sprays water downward through the nozzles to rinse the inner wall of the tank 1. The nozzles are evenly distributed on the surface of the annular pipe. The water inlet is connected to the water pump 602 to ensure that the rinsing coverage is comprehensive.

[0031] The structural advantages of the 304 twisted wire suspension bracket: Eight hooks are symmetrically distributed on the vertical long rod, which can suspend multiple twisted wire bundles with uniform spacing to avoid tangling. The curved connecting rod is welded to the middle and lower end of the vertical long rod to enhance the rigidity of the suspension bracket and make it more stable.

[0032] Quick replacement mechanism: After dyeing is completed, the entire yarn placement rack 3 can be removed and replaced with a new rack to achieve continuous production and improve efficiency. The sealing fit between the fan-shaped frame 2 and the fan-shaped cover 301 ensures that the dye liquor does not overflow or leak during the dyeing process.

[0033] When this utility model is in operation: during the pretreatment of the twisted silk, the silk twisted silk is evenly suspended on the hook of the hanging frame 304 of the twisted silk placement frame 3, and the spacing between each twisted silk bundle is consistent to avoid tangling; During feeding and installation, inject an appropriate amount of water, dye and auxiliaries into the tank 1 through the feed pipe 7. The liquid level should cover the twisted wire. Insert the twisted wire placement rack 3 with the twisted wire suspended into the fan-shaped frame 2. The fan-shaped cover 301 fits into the fan-shaped frame 2 and is sealed by the sealing gasket 302. During heating and temperature control, the control box 11 is started, the heating temperature of the spiral heating tube 10 is set, the temperature sensor 8 monitors the temperature of the dye solution in the tank in real time, and feeds back to the control box 11 to automatically adjust the heating power to ensure temperature stability. During the stirring and dyeing process, the geared motor 501 is turned on to drive the stirring rod 502 to rotate at a low speed. The stirring blades push the dye liquor to circulate, so that the strands are evenly contacted with the dye liquor. During the stirring process, the limiting rod 503 stabilizes the lower end of the stirring rod 502 to prevent swaying from affecting the dyeing effect. When draining the liquid and removing the strands, after dyeing, open the electric butterfly valve 4 through the control box 11 to drain the waste liquid in the tank 1. After the waste liquid is drained, close the electric butterfly valve 4, take out the strand placement rack 3, and transfer the dyed strands to the subsequent processing steps. During rapid changeover and continuous production, immediately insert the new skein placement rack 3 with the skein suspended into the fan-shaped frame 2, and repeat the feeding, heating, and stirring steps to achieve continuous dyeing; When rinsing the tank, start the rinsing mechanism 6, and the water pump 602 is connected to the water supply pipe to draw water from the outside. The water is sprayed downward through the nozzle of the annular spray pipe 603 to rinse the inner wall of the tank 1 and residual dye until the discharged water is clear.
