[0067] In specific use, first, the user needs to fold the protective clothing longitudinally, place it on the belt conveying assembly 55 with the feet towards the device, then put the plastic packaging bag 52 on the gate seat round pipe 44, and then start the winding drive motor 7.

[0068] Then the protective clothing moves to the position where the belt conveying assembly 55 and the roller pressing exhaust assembly 56 contact, under the mutual extrusion of the belt conveying assembly 55 and the roller pressing exhaust assembly 56, the protective clothing can be folded and flattened, and the air in the protective clothing can be exhausted through the collar part of the protective clothing.

[0069] The flattened protective clothing can be prevented from returning with the belt conveying assembly 55 by the guide plate bottom shovel part 61, and the flattened protective clothing can be prevented from being wound by the roller pressing exhaust assembly 56 by the guide plate top shovel part 62.

[0071] Since the winding main shaft 25 has a high rotating speed, the winding main shaft 25 always applies a force to the end of the protective clothing to make the protective clothing climb along the winding main shaft 25, and the protective clothing with the end being pressed into an arc shape can slowly recover to be flat, and in the short time when the protective clothing keeps the arc shape, the protective clothing can pass the top of the winding main shaft 25 and be wound on the winding main shaft 25 to form the winding protective clothing body 26;

[0072] During the increase of the thickness of the winding protective clothing body 26, the sliding screw segment 29 slides together with the arc-shaped induction plate 30 towards the straight guide rail 27, when the thickness of the winding protective clothing body 26 reaches the winding thickness of a complete protective clothing, the screw segment inner thread 36 and the main shaft outer thread 32 are in contact and engagement, and the straight sliding plate 28 slides on the straight guide rail 27 through the transmission of the two, and the winding protective clothing body 26 is pushed out of the winding main shaft 25 into the gate seat circular pipe 44 and the plastic packaging bag 52 through the sliding screw segment 29;

[0073] During the sliding of the straight sliding plate 28 towards the hydraulic material return opening and closing mechanism 3, the sliding plate reset spring 24 is compressed, the main pipe piston 64 extrudes the transmission liquid in the three-way pipe main pipe 48 into the three-way pipe branch pipe 49, and the two sets of closed gate bodies 40 are driven to be separated through the gate driving piston 43, and a space allowing the winding protective clothing body 26 to pass through is formed;

[0074] After the winding protective clothing body 26 is separated from the winding main shaft 25, the sliding screw segment 29 is reset under the elastic force of the screw segment reset spring 31, the main shaft outer thread 32 and the screw segment inner thread 36 are no longer in engagement, and at this time, the straight sliding plate 28 is reset under the action of the gate reset tension spring 41 and the sliding plate reset spring 24.
