Referring to fig. 1 and 2, an embodiment of the present invention relates to a film rolling buffer device, including:

the roller frame comprises a first roller frame 100, wherein the first roller frame 100 comprises first convex parts 110 protruding downwards, a first concave part 120 is formed between every two adjacent first convex parts 110, and a rotatable first buffer roller 130 is arranged on each first convex part 110;

the second roller frame 200, the second roller frame 200 includes second convex portions 210 protruding upwards, a second concave portion 220 is formed between two adjacent second convex portions 210, rotatable second buffer rollers 230 are arranged on the second convex portions 210, and the projections of the first buffer rollers 130 and the second buffer rollers 230 on the horizontal plane are arranged in a staggered manner;

and a driving mechanism 300, wherein the driving mechanism 300 is respectively connected with the first roller frame 100 and the second roller frame 200, in an initial state, the first buffer roller 130 is lower than the second buffer roller 230, the PC film passes through the space between the first buffer roller 130 and the second buffer roller 230, and in a working state, the first roller frame 100 is lifted, and simultaneously, the second roller frame 200 is lowered, so that the first buffer roller 130 is higher than the second buffer roller 230.

The embodiment of the utility model provides a be located before the winding mechanism, under initial condition, in the normal rolling process promptly, the embodiment is out of work, the PC membrane passes between first buffer roller 130 and the second buffer roller 230, realize normal rolling, if the roll-up length of current reel is about to reach appointed meter number, get into operating condition this moment, keep away from gradually between first buffer roller 130 and the second buffer roller 230, the PC membrane forms W shape route wherein, the distance that the PC membrane need pass through is elongated, because draw gradually between first buffer roller 130 and the second buffer roller 230 greatly, have certain pulling force to the PC membrane, consequently this moment the utility model discloses a replace winding mechanism to stimulate the PC membrane, winding mechanism just can stop to rotate, the workman can change the reel during this period, after new reel is more changed, will again the utility model discloses an initial condition is changed.

Wherein, the first buffer roller 130 and the second buffer roller 230 are provided with five strips. In practice, different numbers of first and

second buffer rollers

130, 230 may be provided as desired to provide different lengths of PC film path.

Further, the roller frame further comprises a sliding guide groove 400 arranged in the vertical direction, pulleys 410 are arranged on the side edges of the first roller frame 100 and the second roller frame 200, and the pulleys 410 are clamped in the sliding guide groove 400. The sliding guide groove 400 serves to define a moving path of the first and

second roll frames

100 and 200, a constant speed is required for the driving mechanism 300 to pull the first and

second roll frames

100 and 200, and the sliding guide groove 400 is used to ensure that the positions of the first and

second roll frames

100 and 200 are not greatly deviated, thereby ensuring the stability of the pulling speed.

The driving mechanism 300 includes a transmission chain 310, a rotating motor 320, a driving gear 330 and a driven gear 340, the driving gear 330 is disposed on an output shaft of the rotating motor 320, the driving gear 330 and the driven gear 340 are disposed below the second roller frame 200 and above the first roller frame 100, the transmission chain 310 is connected to the driving gear 330 and the driven gear 340, and the first roller frame 100 and the second roller frame 200 are fixed on the transmission chain 310.

In this embodiment, the transmission chain 310, the rotating motor 320, the driving gear 330 and the driven gear 340 are two, one set corresponds to the first roller frame 100, the other set corresponds to the second roller frame 200, and the speed of the transmission chain 310 can be controlled by controlling the output torque of the rotating motor 320, so as to control the speed of the first roller frame 100 and the second roller frame 200 moving away from each other. Wherein, the line of the driving gear 330 and the driven gear 340 is vertical to the horizontal plane.
