[0001] The present application relates to the field of pad dyeing machines, and in particular to a drying device for pad dyeing machines. Background Art

[0002] Pad dyeing is a dyeing method in which the fabric is immersed in liquid and then subjected to roller pressure, so that the dye penetrates the fabric and the remaining liquid is removed. The pad dyeing method is to immerse the fabric in the dye for a short time, then use a roller to press the dye into the gaps in the fabric, and remove the excess dye, so that the dye is evenly distributed on the fabric.

The high-efficiency drying mechanism of the tie-dyeing machine is provided with a motor, a rotating rod, a first bevel gear, a second bevel gear, a screw rod, a fan, a slide groove and a slider. By starting the motor to drive the rotating rod to rotate, the first bevel gear is driven to rotate at the same time. The first bevel gear can also drive the second bevel gear to rotate, and then the fan on the screw rod can be raised and lowered. The motor is a double-headed motor, which can make two fans blow air up and down to the dried cloth. When drying and air-drying are added, the drying speed of the cloth can be accelerated, and the drying efficiency of the drying mechanism is improved.

[0004] During the drying process, the fan needs to ventilate continuously in order to increase the air circulation speed in the chassis and increase the contact between the fabric and the hot air. The noise generated by the fan during operation can easily affect the surrounding environment. Summary of the invention

[0005] In order to reduce the noise generated by the drying equipment during the drying process, the present application provides a drying equipment for a roller dyeing machine.

[0006] The present application provides a drying device for a pad dyeing machine, which adopts the following technical solution: A drying device for a roller dyeing machine comprises a drying box, a heating component for heating the drying box, and a feeding component, wherein the feeding component comprises a feeding frame, a driving member, a tightening portion, and a swinging member, wherein the tightening portion is used to keep the cloth at the feeding frame in a wide tightened state, the driving member is used to transport the cloth on the feeding frame, and the swinging member is used to drive the feeding frame to swing.

[0007] By adopting the above technical solution, the heating component heats the inside of the drying box, the cloth in the drying box is moved by the driving member, the tensioning part tightens the cloth on the feeding frame, and the swinging member swings the feeding frame. During the swinging process of the feeding frame, the tightened cloth swings with the feeding frame, and the cloth acts as a fan. The movement of the cloth makes the air in the drying box flow quickly, and the heat generated by the heating component quickly contacts the cloth, so that the cloth is dried. By driving the cloth to move through the swinging member, there is no need to use a fan to drive the air flow in the drying box, which greatly reduces the noise generated by the drying box and reduces noise pollution.

[0008] Optionally, the tensioning part includes two tensioning frames, two edge clamping pieces for clamping both sides of the cloth, a bidirectional screw and a tensioning motor. The two tensioning frames are located on both sides of the cloth and are slidably connected to the feeding frame along the width direction of the cloth.

When the cloth needs to be tightened, the staff first matches the two long sides of the cloth to the two edge clamping pieces respectively, and the staff first passes the cloth through the needles on the conveyor belt, and the needles passing through the cloth are inserted into the matching belt. At this time, the long side of the cloth is clamped, and the staff can drive the bidirectional screw to rotate through the tightening motor, so that the two tightening frames move away from each other, and the tightening frames tighten the cloth along the width direction. Since the driving member is used to drive the cloth to be transported, during the conveying process, the cloth and the needles cooperate to drive the conveyor belt to rotate, and the matching belt moves with the conveyor belt under the action of the needles, and the needles on the conveyor belt pierce the subsequent cloth and pierce into the matching belt.

[0012] Optionally, the tensioning frame is provided with an adjusting member for adjusting the distance between the conveyor belt and the matching belt, and the adjusting member includes two sliding blocks, two connecting rods, two matching blocks, two screws and a double-headed motor, the two sliding blocks correspond one-to-one to the two conveying rollers, the sliding blocks are slidingly connected to the tensioning frame along the thickness direction of the cloth, the two sliding blocks correspond one-to-one to the two conveying rollers, the conveying rollers are rotatably connected to the sliding blocks, the two matching blocks correspond one-to-one to the two sliding blocks, the matching blocks are slidably connected to the tensioning frame along the conveying direction of the cloth, the two connecting rods correspond one-to-one to the two sliding blocks, one end of the connecting rod is rotatably connected to the sliding block, and the other end of the connecting rod is rotatably connected to the matching block, the two screws correspond one-to-one to the two matching blocks, the screws are rotatably connected to the tensioning frame, the matching block is threadedly connected to the screw, and the double-headed motor is used to drive the two screws to rotate.

The ratchet is provided on the driven roller, the pawl is rotatably connected to the tensioning frame, and the limiting spring is used for the pawl to be clamped on the ratchet.

[0017] By adopting the above technical solution, since the swinging member drives the feeding frame to swing, the swinging of the feeding frame will pull the cloth at one end of the rotating axis of the feeding frame, and the driven roller has no power source, it is easy to rotate in the opposite direction with the traction of the cloth, so that the cloth is separated from the driving roller; the limiting member limits the reverse rotation of the driven roller, when the cloth is subjected to a traction force opposite to the conveying direction, the pawl engages with the pawl under the action of the limiting spring, and the driven roller cannot move in the opposite direction, and the driven roller and the driving roller limit the cloth from moving in the opposite direction to the conveying direction, and when the driving motor drives the driving roller to rotate, the pawl on the limiting member cannot engage with the ratchet, thereby realizing the unidirectional rotation of the driven roller.
