A right-turning groove 31 for inserting the pin shaft 20 and rotatably connected to the pin shaft 20 is provided at one end of the rotating drum 30 near the motor seat 21, a ring groove 32 is provided on the rotating drum 30, and a slip ring 33 is rotatably provided in the ring groove 32, and a pressing plate 39 for pressing the polyester cloth is symmetrically provided on the slip ring 33, and an adjusting mechanism for controlling the movement of the slip ring 33 is provided in the ring groove 32.

[0024] The screw rod 14 is fixed on the upper and lower ends of the upper and lower fixed shafts 12 and 13 so as to prevent the upper and lower pressure rollers 13 and 9 from sliding on the upper and lower fixed shafts 12 and 13.

[0025] Specifically, a left-turning groove 24 is provided at one end of the motor seat 21 close to the winding roller 19 for the pin shaft 20 to be inserted into and rotatably connected to the pin shaft 20. The left-turning groove 24 is coaxially arranged with the right-turning groove 31. A key rod groove 23 is provided at the end of the left-turning groove 24 away from the pin shaft 20. The output end of the motor 22 is fixedly connected to a key rod 25 rotatably connected to the key rod groove 23. The cross-section of the key rod 25 is square. A slot 26 is provided at one end of the pin shaft 20 close to the key rod 25 for the key rod 25 to be inserted into. The motor 22 drives the key rod 25 to rotate, and the pin shaft 20 is driven to rotate by the engagement of the key rod 25 with the slot 26. The pin shaft 20 on the other side is rotatably connected to the right-turning groove 31, so that the winding roller 19 rotates to reel in the polyester cloth.

[0026] Specifically, the slip ring 33 is symmetrically provided with a rod slot 34, a pressing plate 39 is fixedly connected to a rod 35 for inserting into the rod slot 34, a limiting slot 36 is provided at the bottom of the rod slot 34, a limiting plate 37 fixedly connected to the rod 35 is slidably provided in the limiting slot 36, and a compression spring 38 is fixedly provided at one end of the limiting plate 37 close to the rod 35, which abuts against the inner wall of the limiting slot 36. The compression spring 38 is sleeved on the rod 35. When the polyester cloth is rolled up, Pulling the pressure plate 39 causes the insertion rod 35 to slide in the insertion rod groove 34 and drives the limit plate 37 to move and compress the pressure spring 38, winding the polyester cloth onto the winding roller 19, loosening the pressure plate 39, and under the elastic force of the pressure spring 38, the pressure plate 39 presses the polyester cloth onto the winding roller 19, and the polyester cloth can be wound. During the winding process, the rotating drum 30 rotates with the winding roller 19, so that the pressure plate 37 will not interfere with the rotation of the winding roller 19.

[0027] Specifically, the adjustment mechanism includes a screw 41 and an adjusting button 42. The screw 41 is rotatably arranged on the inner wall of the annular groove 32 and passes through the side wall of the rotating drum 30 away from the winding roller 19. The end of the screw 41 located outside the rotating drum 30 is fixedly connected to the adjusting button 42. The screw 41 passes through the slip ring 33 and is threadedly connected to the slip ring 33. Rotating the adjusting button 42 drives the screw 41 to rotate, so that the slip ring 33 slides in the annular groove 32, so that the clamping plate 39 is separated from the winding roller 19, making it convenient to collect the polyester cloth roll on the winding roller 19.

[0028] Specifically, a limit column 40 is fixedly provided at the end of the fixing rod 29 to be rotatably connected to the rotating drum 30. The diameter of the limit column 40 is larger than the fixing rod 29. The limit column 40 is limited to prevent the rotating drum 30 and the fixing rod 29 from axial movement. When the movable seat 28 moves, the rotating drum 30 can be driven to move, so that the pin shaft 20 disengages from the right rotation groove 31, which is convenient for collecting the polyester cloth roll on the winding roller 19. The movable seat 28 is provided with a stabilizing groove 43 rotatably connected to the rotating drum 30. When the rotating drum 30 follows the winding roller 19 to rotate, the rotating drum 30 rotates in the stabilizing groove 43. The stabilizing groove 43 provides supporting force for the rotating drum 30, thereby ensuring the stability of the movement of the winding roller 19. The inner wall of the drying box 1 is symmetrically fixed with track plates 44 on both sides of the movable seat 28, which are attached to the side walls of the movable seat 28. The track plates 44 can limit the movable seat 28 to ensure the stability of the movable seat 28 when it moves.

[0029] A specific application example of this embodiment is:

[0030] When the device is in use, the knob 16 is turned to drive the screw rod 14 to rotate, and the threaded connection between the threaded groove 15 on the slider 11 and the screw rod 14 causes the slider 11 to slide in the slide groove 10, so that the upper fixed shaft 12 is lowered, thereby adjusting the distance between the upper pressing roller 13 and the lower pressing roller 9, and adjusting the degree of drying of the polyester cloth. The polyester cloth passes between the lower pressing roller 9 and the upper pressing roller 13, and the moisture in the polyester cloth is squeezed into the water collecting tank 6 by the lower pressing roller 9 and the upper pressing roller 13, and then the polyester cloth enters the drying tank through the cloth feeding tank 5. In the drying box 1, the polyester cloth is sequentially wound on the tensioning roller 18 to maintain the tension state of the polyester cloth. The electric heating tube 2 cooperates with the fan 3 to quickly air-dry the polyester cloth (this is the prior art of the comparative document). The setting of multiple tensioning rollers 18 allows the polyester cloth to have sufficient drying time to ensure the drying effect. Finally, the polyester is arranged on the winding roller 19 for winding, and the pressing plate 39 is pulled to make the insertion rod 35 slide in the insertion rod groove 34 and drive the limit plate 37 to move the compression spring 38, so that the polyester cloth is wound and attached to the winding roller 19. , loosen the pressing plate 39, and under the elastic force of the pressing spring 38, the pressing plate 39 presses the polyester cloth on the winding roller 19, and the polyester cloth can be wound. Start the motor 22, and the motor 22 drives the key rod 25 to rotate. The engagement of the key rod 25 with the card slot 26 drives the pin shaft 20 to rotate, and the other side pin shaft 20 is rotatably connected to the right turning slot 31, so that the winding roller 19 rotates to wind the polyester cloth. The staff can enter and exit the drying box 1 from the rear door 4 to dry and wind the polyester cloth. After winding, the adjusting knob 42 is turned to drive the screw 41 to rotate, so that the slip ring 33 slides in the ring groove 32 in the direction away from the winding roller 19, so that the pressing plate 39 is separated from the winding roller 19, and then the hydraulic mechanism 27 is started to drive the movable seat 28 to move away from the winding roller 19, so that the rotating drum 30 moves away from the winding roller 19, so that the pin shaft 20 is separated from the right turning groove 31, and the winding roller 19 can be removed, so that the polyester cloth roll that has been dried and wound is collected, thereby improving work efficiency.
