Preferably, the slideways are respectively provided on both sides of each of the rollers, and both ends of the rollers are connected with the sliders, and the adjusting device is also provided with a device for adjusting the lifting height of the rollers. Cylinders are arranged so that each of the rolls is staggered, and the tension of the stored film is adjusted to the appropriate tension to match the production speed and winding speed of the film.

Preferably, the number of the rollers is at least 2, which is convenient for adjusting the storage length of the film, adjusting the film tension, and preventing film accumulation and damage.

The beneficial effects of the present utility model are: the roller set of the present utility model can rewind the film in advance, which provides more time for manual roll change and effectively improves the production efficiency; the adjusting device can further increase the storage length of the film, which is also beneficial to Adjust the tension of the film to match the production speed and winding speed of the film to avoid the accumulation of the film, and also avoid the film damage due to excessive tension during the winding process.

Detailed ways

The technical solution of the present patent will be described in further detail below in conjunction with specific embodiments.

In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "front end", "rear end", etc. are based on the drawings. The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. limit.

As shown in Figures 1-3, a film storage rack includes a support frame 10, the front end of the support frame is close to the film production equipment, and the rear end of the support frame is close to the film winding equipment. The support frame 10 is provided with an adjusting device 16 , and a plurality of movable rollers 14 are provided on the adjusting device 16 , and the number of the rollers 14 is at least two. The film 12 is staggered across several rolls 14 . The adjusting device 16 can adjust the lifting height of the roller 14 to prevent the film 12 from accumulating due to the production speed of the film 12 being faster than the winding speed. The front end of the support frame 10 is provided with a rotatable roller group 18. The roller group 18 includes a rotating roller 183 and an upper roller 181 and a lower roller 182 symmetrically arranged on the rotating roller 183. The axes are parallel to each other, and a motor 184 for driving the rotating roller 183 to rotate is also included. The roller group 18 is in the shape of a fork. The upper roller 181 and the lower roller 182 are connected to a rotating roller 183 , and the rotating roller 183 is connected to a motor 184 to drive the upper roller 183 and the lower roller 184 to rotate. In order to drive the roller group 18 to rotate, it is beneficial to roll up the excess film 12 in advance, so as to avoid the accumulation of the film 12 during the winding process of the film 12 .

The adjusting device 16 includes several vertical slideways 161 connecting the top and bottom of the support frame 10 , and a slider 162 arranged on the slideways 161 . Slideways 161 are respectively provided on both sides of each roller 14, and both ends of the roller 14 are connected to the slider 162. The adjusting device 16 is also provided with a cylinder (not shown) for adjusting the lifting height of the roller 14. The slider 162 drives the rollers 14 to move up or down along the slideway 161 , so that each roller 14 is staggered and adjusted to a suitable tension of the stored film 12 to match the production speed and winding speed of the film 12 .

The roller group 18 and several rollers 14 are arranged on the support frame 10 in parallel with the axes, and the film 12 passes through the roller group 18 and the roller 14 respectively in an S-shaped trend, which is convenient for the roller group 18 to pre-wind the film 12, which is beneficial to increase the pre-storage capacity. length.

As shown in FIG. 4 , when the utility model is in use, the film 12 is passed through the roller group 18 and the roller 14 respectively in an S-shaped trend.

During manual roll change, in order to maintain the normal operation of the production machine, the height of each roll 14 is first adjusted by the adjusting device 16 to maximize the storage length of the film and prevent the film from accumulating at the winding device; if the manual roll change is still not over , and then drive the roller group 18 to rotate through the motor 184, adjust the height of the roller 14 at the same time, adjust the storage length of the film, and pre-roll the film 12 passing through the roller 14 and the film 12 that is being continuously produced on the roller group 18;

After the new reel is replaced, the motor 184 drives the roller group 18 to rotate in the reverse direction, and releases the pre-stored film 12, so that the film 12 is rewound on the new reel, and the adjusting device 16 can match the speed and rewinding of the production film. The speed, the lifting height of the roller 14 and the tension of the film are adjusted to avoid damage to the film during the winding process.
