step two, when the translation block 43 moves to the end of the rotation screw rod 42, the circular bayonet 422 slides and rotates on the surface of the translation block 43 and compresses the elastic part 421, when the circular bayonet 422 is just clamped and enters the matching hole 431 on the surface of the translation block 43, the rotation screw rod 42 drives the translation block 43 to synchronously rotate, the rotation of the translation block 43 drives the winding plate 45 and the clamping plate 46 to rotate, so as to drive the winding film to wind on the surface of the winding plate 45, the film winding roller 21 carries out rotary feeding, the film winding curved block 22, the first rotating wheel 23 and the second rotating wheel 24 move, the continuous adhesion and separation are carried out between the bottom surface of the film winding curved block 22 and the surface of the transported film sheet, meanwhile, the elastic part 221 is upwards compressed in the adhesion process, so that the film winding curved block 22 is tightly attached to the film sheet, and therefore, the fine dust on the surface of the film sheet is adsorbed, the function of dust-free sticking of the film is achieved;

step three, in the winding process, the thickness of the winding film on the surface of the winding plate 45 is continuously increased, when the thickness reaches a certain degree, the stressed slide rod 52 is extruded, the stressed slide rod 52 slides on the fixed rod 51 after being extruded, the rack slide plate 54 is driven by the thrust connecting rod 53 to slide towards the inside of the slide plate seat 56 and compress the elastic component 55, due to meshing effect, the rack slide plate 54 drives the rotating gear 57 to rotate, so that the rotating cutter 58 is driven to rotate, the rotating cutter 58 rotates to cut off the winding film to be transmitted, and damage caused by overload rotation due to overlarge winding thickness is prevented;

step four, when the film is cut, the winding driving part 41 at the other end of the semicircular connecting rod 32 starts to perform the operation of the step one, and the winding driving part 41 at the winding end rotates reversely to loosen the clamping plate 46 and the winding plate 45, at this time, the wound film is hung on the winding plate 45, and at the same time, the reversing driving part 31 starts to operate, the movement of the reversing driving part 31 drives the semicircular connecting rod 32 to rotate, the rotation of the semicircular connecting rod 32 drives the winding driving parts 41 at the two ends thereof to rotate, at this time, the rotary spring assembly 411 connected behind the forward winding driving part 41 is in a loose state, at this time, the chute round block 412 slides in the curved chute frame 33, the forward winding driving part 41 cannot be pulled due to the loose state of the rotary spring assembly 411, and the reverse rotation of the winding driving part 41 at the other end, the rotary spring assembly 411 at this end is tightened, at the moment, the chute round block 412 slides in the curved chute frame 33, the winding driving part 41 moves to a position close to the curved chute frame 33 due to the arc design, and at the moment, the two groups of winding plates 45 at the end move away, so that the winding films cut off by winding fall into the blanking channel 25, and meanwhile, the reversing driving part 31 continuously performs forward and reverse switching to prevent mechanism interference during operation, so that the function of automatically cutting and blanking is achieved;

fifthly, after dust removal of the film is completed, the film reaches the position below the pressing component 6, and when the PS plate below the film is in place, the glass conveying table 102 conveys the glass plate to the position above the pressing part 66;

step six, at this time, the pressing driving part 61 starts to operate, the operation of the pressing driving part 61 pushes the pressing slider 62 to move downwards, the downward movement of the pressing slider 62 drives the L-shaped plate 65 to move downwards, and further drives the pressing part 66 to push the film downwards onto the PS plate, when the pressing slider 62 continues to move downwards, the fixed sliding pin 64 slides on the pressing curved groove 631 inside the pressing slider 63, at this time, due to the curved structure of the pressing curved groove 631, the pressing slider 63 and the symmetrical end thereof continuously stretch the extension spring 67, at the same time, the glass plate above the pressing part 66 slides above the pressing part 66 under the blocking effect of the glass baffle plate 104, at this time, the pressing part 66 slides from the middle to the two ends on the film plate, so that bubbles between the film plate and the PS plate are removed, and at the same time, when the pressing part 66 slides to the tail end of the film, the glass plate presses down on the film under the pressure of 68 to press the film, prevent the film from rebounding to generate bubbles, thereby achieving the function of automatically removing the internal bubbles and preventing the influence on printing.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
