[0069] In this embodiment, when the second support plate 144 is inserted into the first support shaft 142, the drive motor 141 is started, and the drive motor 141 will drive the first support shaft 142, the first support plate 143 and the second support plate 144 to rotate synchronously. At this time, the man-made cotton fabric wrapped around the first support plate 143 and the second support plate 144 can be driven to rotate to improve the dyeing efficiency; when the second support plate 144 is separated from the first support shaft 142 and the second support plate 144 is limited in position, the drive motor 141 is started, and the drive motor 141 will drive the first support shaft 142 and the first support plate 143 to rotate synchronously. At this time, the man-made cotton fabric wrapped around the first support plate 143 and the second support plate 144 can be squeezed to squeeze out excess dye.

[0070] like Figure 3 As shown, in one embodiment of the present application, the second support plate 144 includes a hanging plate 144a and a boss 144b.

[0071] The hanging plate 144a is disposed at the bottom of the first supporting shaft 142, and the rayon fabric is wound around the hanging plate 144a during use.

[0072] The boss 144 b is disposed on the top of the hanging plate 144 a , the boss 144 b is fixedly connected to the middle of the hanging plate 144 a , the top of the boss 144 b is inserted into the first supporting shaft 142 , and the boss 144 b is fixedly connected to the spring 146 .

[0073] In this embodiment, when the boss 144b is inserted into the bottom of the first support shaft 142, the hanging plate 144a rotates synchronously with the first support plate 143 and the first support shaft 142; when the boss 144b is disengaged from the bottom of the first support shaft 142 and the hanging plate 144a is limited in position, the drive motor 141 is started, and the drive motor 141 can only drive the first support shaft 142 and the first support plate 143 to rotate synchronously.

[0074] like Figure 4 to Figure 5 As shown, in one embodiment of the present application, the support frame 13 includes a cover plate 131 , a first positioning rod 132 , a second positioning rod 133 , a first electric push rod 134 and a second electric push rod 135 .

[0075] The cover plate 131 is disposed on the top of the liquid storage barrel 12 , and the cover plate 131 covers the liquid storage cavity 121 .

[0076] The first positioning rod 132 is disposed on one side of the cover plate 131 , the first positioning rod 132 is fixedly connected to the cover plate 131 , and the first positioning rod 132 passes through the liquid storage barrel 12 .

[0077] The second positioning rod 133 is disposed on the other side of the cover plate 131 , the second positioning rod 133 is fixedly connected to the cover plate 131 , and the second positioning rod 133 passes through the liquid storage barrel 12 .

[0078] The first electric push rod 134 is arranged on one side of the cover plate 131 , the first electric push rod 134 is arranged between the first positioning rod 132 and the second positioning rod 133 , one end of the first electric push rod 134 is fixedly connected to the cover plate 131 , and the other end of the first electric push rod 134 is fixedly connected to the base 11 .

[0079] The second electric push rod 135 is arranged on the other side of the cover plate 131, and the second electric push rod 135 is arranged between the first positioning rod 132 and the second positioning rod 133. One end of the second electric push rod 135 is fixedly connected to the cover plate 131, and the other end of the second electric push rod 135 is fixedly connected to the base 11.

[0080] A first limit block 15 is fixedly connected to one side of the liquid storage barrel 12 , and the first positioning rod 132 passes through the first limit block 15 ; a second limit block 16 is fixedly connected to the other side of the liquid storage barrel 12 , and the second positioning rod 133 passes through the second limit block 16 .

[0081] In this embodiment, the first electric push rod 134 and the second electric push rod 135 are started simultaneously to drive the cover 131 to move so that the cover 131 opens or seals the liquid storage chamber 121. When the cover 131 moves, the first positioning rod 132 will slide relative to the first limit block 15 and the second positioning rod 133 will slide relative to the second limit block 16, thereby increasing the stability of the cover when it moves.

[0082] like Figures 3 to 6 As shown, in one embodiment of the present application, a limiting hole 142a is opened at the bottom of the first support shaft 142, the positioning block 145 is rotatably disposed inside the limiting hole 142a, and the boss 144b is inserted into the limiting hole 142a.

[0083] A first locking block 17 is fixedly connected to one side of the boss 144 b , and a second locking block 18 is fixedly connected to the other side of the boss 144 b . The first locking block 17 is inserted into the first support shaft 142 , and the second locking block 18 is inserted into the first support shaft 142 .

[0090] In this embodiment, the first electric push rod 134 and the second electric push rod 135 are started synchronously to drive the cover plate 131 to move, thereby moving the hanging plate 144a. When the hanging plate 144a moves to the same horizontal height as the first baffle plate 19 and the second baffle plate 20, the drive motor 141 is started, and the drive motor 141 drives the first support plate 143 and the hanging plate 144a to rotate synchronously. When the hanging plate 144a is stuck between the first baffle plate 19 and the second baffle plate 20, the first electric push rod 134 and the second electric push rod 135 are started synchronously again to make the first locking block 17 on the boss 144b disengage from the first locking groove 142b and the second locking block 18 on the boss 144b disengage from the second locking groove 142c, and then the drive motor 141 is started again to drive the first support plate 143 to rotate. At this time, the hanging plate 144a does not rotate, thereby squeezing the man-made cotton fabric wrapped around the first support plate 143 and the hanging plate 144a, thereby promoting the discharge of excess dye.
