[0008] By adopting the above technical solution, when in use, the operator takes one end of the cloth out of the dyeing machine body, and clamps the cloth on the driving belt through the clamping piece on the driving belt. As the driving motor drives the cloth outlet roller to rotate, the cloth outlet roller drives the driving belt to rotate through a plurality of guide rollers and the driving roller, so that the cloth moves to the cloth outlet roller along with the clamping piece, making it convenient for the operator to wind the cloth onto the cloth outlet roller.

[0009] Optionally, the clamping member includes a rotating plate, a piercing needle for piercing the cloth, and a loosening structure for driving the piercing needle to pierce out of the cloth, the rotating plate is connected to the driving belt and rotates in a direction approaching or away from the driving belt, the piercing needle is arranged on the rotating plate, and the tip of the piercing needle is located between the rotating plate and the driving belt.

[0010] By adopting the above technical solution, when in use, the operator places the cloth between the rotating plate and the driving belt, and then the threading needle is inserted into the cloth to clamp the cloth on the driving belt. Then one end of the cloth moves to the cloth outlet roller along the driving belt, and then the loosening structure drives the threading needle to move in the direction of threading out the cloth to loosen the cloth.

[0011] Optionally, the clamping member also includes a maintaining spring for maintaining the state of the threading needle inserted between the rotating plate and the driving belt, the threading needle is slidably connected to the rotating plate, and the loosening structure includes a water pressure roller, the water pressure roller is rotatably connected to the cloth output frame and is located directly above the cloth output roller, the water pressure roller and the cloth output roller are used to squeeze the cloth, and the water pressure roller is provided with a threading ring groove for the threading needle to penetrate; a delay component for delaying the resetting of the maintaining spring is provided on the rotating plate.

[0012] By adopting the above technical scheme, when in use, the driving belt drives the rotating plate and the threading needle to move to the cloth discharge roller, the water pressure roller rotates the rotating plate in the direction close to the driving belt, the threading needle slides on the rotating plate and penetrates into the threading ring groove of the water pressure roller, so that the distance between the cloth and the rotating plate is shortened, and then the rotating plate rotates in the downward direction under the action of gravity, and the delay component prolongs the time for resetting the threading needle, so that the cloth and the threading needle are separated; the water pressure roller separates the cloth from the threading needle while pressing water on the discharged cloth, so that the cloth is automatically separated from the threading needle.

[0013] Optionally, a maintaining torsion spring for maintaining the inclined state between the rotating plate and the driving belt is provided between the rotating plate and the driving belt.

[0014] By adopting the above technical solution, after the rotating plate is separated from between the water pressure roller and the cloth outlet roller, the rotating plate moves in a direction away from the driving belt under the action of the maintaining torsion spring, so that the speed at which the threading needle slides out of the cloth is accelerated.

[0016] By adopting the above technical solution, when the water pressure roller drives the rotating plate to rotate in a direction close to the driving belt, the adjusting part adjusts the ventilation hole to become larger, so that the outside air can quickly enter the fixed sleeve. After the rotating plate separates from the water pressure roller and moves in a direction away from the driving belt, the adjusting part adjusts the ventilation hole to become smaller, so that the installation barrel body receives a certain resistance when moving in the direction of penetrating into the fixed sleeve, thereby increasing the time for resetting the penetration needle.

[0017] Optionally, the adjusting member includes an adjusting spring piece, which is disposed in the fixing sleeve and is used to block a portion of the ventilation hole.

[0018] By adopting the above technical solution, when the installation barrel body moves in a direction away from the driving belt, the adjusting spring piece is deflected in a direction away from the ventilation hole, so that the effective aperture of the ventilation hole becomes larger, and the outside air quickly enters the fixed sleeve through the ventilation hole; when the installation barrel body moves in a direction close to the driving belt, the air inside the fixed sleeve drives the adjusting spring piece to collide with the inner wall of the fixed sleeve, so that the effective aperture of the ventilation hole is reduced, thereby realizing the adjustment of the air flow of the ventilation hole.

[0019] Optionally, a disengagement component is provided between the clamping member and the driving belt for disengaging the clamping member from the driving belt, the disengagement component includes a flexible sleeve and a blocking structure for blocking the flexible sleeve, the flexible sleeve is slidably sleeved on the driving belt, a limiting groove for limiting the flexible sleeve is provided on the outer side wall of the driving belt, and the clamping member is provided on the flexible sleeve.

[0020] By adopting the above technical solution, when in use, the flexible sleeve is located in the limiting groove, so that the clamping member on the flexible sleeve and the driving belt are relatively fixed, and after the clamping member drives the cloth to the cloth discharge roller, the clamping member loosens the cloth, and when the flexible sleeve is located below the cloth discharge roller, under the action of gravity of the flexible sleeve, the flexible sleeve disengages from the limiting groove, and then the blocking structure blocks the flexible sleeve, so that the clamping member and the driving belt are automatically disengaged after the clamping member loosens the cloth, thereby reducing the occurrence of damage to the cloth by the flexible sleeve and facilitating the operation of the operator.
