The two sides of the top end of the bottom plate component 107 are arc-shaped structures and are in contact with the bottom of the pushing component 104. After the pushing component 104 moves downward and resets, with the help of elasticity, the collision force is eliminated, avoiding large collisions and abnormal noises; a top piece structure 2; the top piece structure 2 is installed above the device body 1. The top piece structure 2 is provided with a moving head structure 203 through a sliding groove 201. A blade 208 is inserted and installed at the top end of the moving head structure 203 through a fixing plate 204. The fixing plate 204 is provided with a manipulable part 207 that can be freely pulled out through a through groove 205. The inner end of the manipulable part 207 is in contact with the blade 208, and the fixing of the blade 208 can be conveniently released through the manipulable part 207, so that the blade 208 can be quickly pulled out and installed, improving the replacement efficiency of the blade 208.

[0025] In the embodiments of the present disclosure, as Figure 3 and Figure 4As shown in the figure, a winding assembly 101 is installed at the front end of the device body 1. The winding assembly 101 is connected to the motor through a transmission structure and is driven by the motor to rotate, generating a winding force. A bracket is installed inside the device body 1, and the bracket is located on both sides of the winding assembly 101. The top end of the bracket is connected to the top piece structure 2. A guide roller assembly 102 is installed at the top end of the device body 1 to control the guiding and moving winding of the PI protective film. On both sides of the inner part of the front end of the device body 1, a hydraulic cylinder 103 is respectively fixed. The telescopic end of the hydraulic cylinder 103 is connected to the pushing assembly 104. By means of the telescopic force, the pushing assembly 104 and the winding assembly 101 are controlled to move up and down. The front end of the pushing assembly 104 is a wedge-shaped structure, and the pushing assembly 104 is located directly below the winding assembly 101. An arc-shaped positioning groove 105 is opened at the middle position of the top end of the pushing assembly 104 for positioning and installing the winding assembly 101. A T-shaped installation groove 106 is opened on the side of the pushing assembly 104 for inserting and fixing the fixing head 108.

[0026] In the embodiment of the present disclosure, as Figure 5 with Figure 6 shown in the figure, a T-shaped chute 201 is opened at the top end of the top piece structure 2 to enable the moving head structure 203 to guide and displace inside it. A threaded rod is inserted into the chute 201, and the outer end of the threaded rod is connected to the motor and is driven to rotate to control the reciprocating movement of the moving head structure 203. Two arc-shaped support rods 202 are fixed at the top end of the top piece structure 2. A moving head structure 203 is inserted into the chute 201, and the threaded rod is inserted into the moving head structure 203 to rotate. A fixing plate 204 is welded and fixed at the top end of the moving head structure 203 for positioning and installing the blade 208. A through groove 205 is opened at the middle position of the fixing plate 204. A side rod structure 206 is respectively fixed on both sides of the fixing plate 204. The side rod structure 206 is located on the outer sides of both sides of the through groove 205. A spring is sleeved on the outer part of the side rod structure 206. The spring continuously pushes the control part 207 to displace. After the control part 207 is displaced, it contacts the blade 208 to improve the fixing effect on the blade 208.

[0027] Working principle of this embodiment: When it is necessary to wind up the PI protective film, the winding assembly 101 can be controlled to roll above the pushing assembly 104, so that the winding assembly 101 is embedded into the positioning groove 105 for positioning. Then, the hydraulic cylinder 103 is controlled to operate, and the hydraulic cylinder 103 drives the pushing assembly 104 and the winding assembly 101 to rise. After reaching an appropriate height, the connection rotating structure is controlled to be connected to the winding assembly 101. Then, the pushing assembly 104 is controlled to move downward to reset. When resetting, the bottom plate assembly 107 and the fixed head 108 are squeezed, and with the help of elasticity, the collision force is eliminated. Then, the winding assembly 101 is controlled to rotate, so that the PI protective film is wound outside the winding assembly 101. After winding is completed, the motor is controlled to drive the screw to rotate, so that the moving head structure 203 reciprocates, and the PI protective film is cut off by the blade 208. When the blade 208 is worn after being used multiple times, the control part 207 is directly pulled to displace, and then the blade 208 is pulled up to remove the blade 208. A new blade 208 is inserted, and the control part 207 is no longer pulled, so that the spring continuously pushes the control part 207 to displace, squeezing and limiting the blade 208, improving the replacement efficiency.
