Description

TECHNICAL FIELD

[0001] The utility model relates to overturning equipment field especially relates to a plate turnover device. BACKGROUND

[0002] In the production of plate materials, it is usually necessary to process the plate materials on both sides. The existing overturning process is to complete the front and back overturning of the plate materials by the turnover device to complete the double-sided processing of the plate materials.

[0003] In the prior art, the patent for invention with publication number CN109382693A provides a turnover device for overturning plate-shaped objects, which needs to first clamp the plate-shaped object in the clamping groove of the two turnover pieces, and then drive the plate-shaped object (plate) to overturn 180°. Although this kind of device can realize the processing of the plate materials on the overturning station, the feeding and discharging of the plate-shaped objects and the assembly of the plate-shaped objects and the turnover pieces all need manual operation, and the overturning of the plate materials cannot be realized synchronously in the process of plate material conveying.

[0004] For example, the patent for invention with authorized announcement number CN110723513B provides a plate material turnover device with a turnover wheel, wherein the turnover wheel arranged between the front conveying belt and the rear conveying belt realizes the turning of the plate materials during conveying, and improves the automation degree of the plate material overturning. However, the turnover wheel only has the function of overturning the plate materials, and cannot drive the plate materials to translate synchronously during overturning.

The operation precision of the slide rod and the push block is required to be high, otherwise the plate materials may not be inputted / outputted in time, and the plate materials may fall off.
