The first elastic member 46 and the second elastic member 48 are arranged, so that two ends of the winding roller 40 are always pulled by the elastic members, and when the winding roller 40 deflects, the first elastic member 46 and the second elastic member 48 can enable the winding roller 40 to be always in the middle position through elastic deformation, thereby preventing a part of base film from being incapable of being wound on the roller due to excessive deflection of the winding roller 40 during deflection, and ensuring that the winding device 100 works smoothly.
The winding device 100 of the present invention works substantially as follows:
under a normal working state, the winding roller 40 winds a base film, the extrusion roller 50 abuts against the base film, so that the base film is smoothly wound, the base film reversely abuts against the extrusion roller 50 along with the increase of the wound base film, the extrusion roller 50 drives the second sliding block 22 to move towards the first hydraulic pipe 23, the second sliding block 22 extrudes liquid in the first hydraulic pipe 23 to move towards the first sliding block 21, the first sliding block 21 is further pushed to slide in the first sliding groove 111, meanwhile, the first sliding block 21 drives the first fixing plate 43 to move through the first universal joint 41, and the first fixing plate 43 drives the winding roller 40 to move together through the first transfer shaft 45 and the first elastic piece 46; similarly, on the other side, the squeeze roller 50 drives the fourth sliding block 32 to move towards the second hydraulic pipe 33, the fourth sliding block 32 squeezes the liquid in the second hydraulic pipe 33 to move towards the third sliding block 31, further push the third sliding block 31 to slide in the second sliding groove 121, meanwhile, the third sliding block 31 drives the second fixing plate 44 to move through the second universal joint 42, the second fixing plate 44 drives the winding roller 40 to move together through the second transfer shaft 47 and the second elastic piece 48, and then the whole movement of the winding roller 40 is realized, thereby increasing the space of the winding roller 40 for winding the base film, and being beneficial to expanding the application range of the winding device 100.
When the winding roller 40 winds the base film, one end of the base film is tighter and the other end is looser, the working process is roughly as follows (taking the example that the winding at the left end is looser and the winding at the right end is tighter):
when the winding roller 40 right-hand member base film is comparatively tight, the winding roller 40 takes place and deflects around, make the right-hand member more forward, thereby make third sliding block 31 remove to second hydraulic tube 33 direction, and then make fourth sliding block 32 downstream, make extrusion roller 50 slope, the more inseparable base film that leans on winding roller 40 of right-hand member, thereby make the base film of coiling tighter, and because winding roller 40 has the trend of returning positive under first elastic component 46 and second elastic component 48's effect, make the base film right side receive winding roller 40's pulling force bigger, thereby make winding roller 40 can reply to balanced state gradually, so set up, can share the local too loose of base film in great length, thereby the possibility of crease appears when reducing the base film and coiling, effectively improve the coiling effect of base film.
The base film has a certain elasticity, and the length of the base film can be adjusted by applying different pulling forces.
When the left end is wound tightly and the right end is wound loosely, the same principle is carried out.
