The working principle of the specific embodiment is as follows: when the device is used, according to the thickness of a plate and the radian of a plate to be rolled, the two lower rollers 4 are driven to move up and down through the two lifting mechanisms 7 respectively until the two lower rollers 4 reach proper positions, then bolts on the sleeve plate 15 are loosened as required, the limiting mechanism 10 is loosened, the supporting frame 8 is moved upwards until the proper positions are reached, the supporting frame 8 is limited through the limiting mechanism 10, the bolts on the sleeve plate 15 are screwed, the sleeve plate 15 and the inserting plate 16 are locked, the plate is inserted from the lower roller 4 on one side and is positioned on the lower side of the upper roller 5 when the device is operated, the upper side of the plate is wound to the upper side of the limiting wheel 13 after the plate is rolled up, the plate is limited and supported, and therefore the processing of the plate is convenient, after the processing is finished, the rolling motor 12 is started, the rolling motor 12 drives the wire winding wheel 11 to rotate, the wire winding wheel 11 winds the connecting rope 18, the connecting rope 18 drives the sleeve plate 15 to rotate towards the upper part of the front side, so that the sleeve plate 15 and the inserting plate 16 are separated from the second fixing frame 14, then the coiled plate is taken down, the winding motor 12 is started reversely, the connecting rope 18 is released, the sleeve plate 15 and the inserting plate 16 rotate towards one side of the second fixing frame 14 under the elastic force of the self-elastic hinge until the inserting holes in the sleeve plate 15 and the inserting plate 16 are respectively sleeved on the convex rods on the second fixing frame 14, and the unprocessed plate is placed between the upper roller 5 and the lower roller 4 again for processing;

when the first fixing frame 6 is driven to move by the lifting mechanism 7, the electric push rod 7-3 is started, the electric push rod 7-3 drives the push plate 7-2 to move upwards, the push plate 7-2 pushes the upper sides of the connecting rods 7-1 at two sides to rotate towards two sides by taking the lower end as an axial point, so that the upper ends of the connecting rods 7-1 slide at two sides respectively, the lower rollers 4 are pushed, and the lower rollers 4 move to proper positions;

when the support frame 8 is limited by the limiting mechanism 10, the support frame 8 is moved upwards, the support frame 8 drives the limiting wheel 13 to move upwards, at the moment, the limiting rack 10-2 moves towards one side of the partition plate 10-3 under the pushing of the supporting rack 10-1, the spring 10-4 is further compressed, the movement of the supporting rack 10-1 is not influenced, after the support frame is moved to a proper position, the limiting rack 10-2 moves towards two sides under the elastic force of the spring 10-4 until the limiting rack 10-2 is abutted against the supporting rack 10-1, the supporting rack 10-1 is further limited, when the support frame needs to move downwards, the two limiting racks 10-2 are manually moved towards one side of the partition plate 10-3, so that the limiting racks 10-2 are separated from the supporting rack 10-1, the supporting frame 8 moves downwards until a proper position is reached, and then the limiting rack 10-2 is loosened, so that the supporting rack 10-1 is limited, and the supporting frame 8 is prevented from moving downwards.

Compared with the prior art, the beneficial effects of the embodiment are as follows:

1. the upper side of the upper roller 5 is provided with the limiting wheel 13, and the limiting wheel 13 can limit the bent upper side of the plate, so that manual support is not needed, and labor force is saved;

2. the upper roller 5 and the limiting wheel 13 are supported by a second fixing frame 14, the second fixing frame 14 is arranged in an L shape, and the second fixing frame 14 is fixed on the rear supporting plate 3 and the supporting frame 8 respectively, so that the upper roller 5 and the limiting wheel 13 can be supported while operation is not influenced;

3. a sleeve plate 15 and an inserting plate 16 are respectively arranged on the front side of the second fixing frame 14, the upper side of the inserting plate 16 is screwed with a transverse plate of the support frame 8 through a self-elastic hinge, and a fixing buckle 17 on the sleeve plate 15 is connected with the take-up pulley 11 through a connecting rope 18, so that the rotation of the sleeve plate 15 can be conveniently controlled, and the blanking is convenient;

4. the lifting mechanism 7 is arranged on the lower side of the lower roller 4, the lifting mechanism 7 can respectively drive the first fixing frame 6 to move up and down, and then the plate can be adjusted according to the required rolling degree of the plate, so that the operation requirement is met;

5. support frame 8 is connected with back backup pad 3 through stop gear 10 to can adjust the position of support frame 8 according to the diameter that panel rolled up to, and after adjusting, carry on spacingly through stop gear 10 to the position of support frame 8, satisfy required requirement.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
