Bending forming device in plastic box bending forming machine

Abstract

The invention discloses a bending forming device in a plastic box bending forming machine. A machine frame above a material frame is provided with a mold table having a cross section in a parallelogram shape; one end of the mold table is mounted on the machine frame, and the other end of the mold table hangs in the air; the machine frame is provided with a suction cup cylinder; the suction cup cylinder is provided with a lifting frame; the lifting frame is symmetrically hinged with a pair of suction cup brackets; the outer side end of each of the two suction cup brackets is provided with a suction cup, and the inner side ends of the two suction cup brackets are simultaneously hinged with a movable shaft; a piston rod of the suction cup cylinder stretches out and draws back to drive the two suction cup brackets to swing around the movable shaft, so that the suction cups can suck a plastic plate, and the plastic plate is allowed to be blended along seamed edges of the bottom of the mold table; parts, above two sides of the mold table, of the machine frame are each provided with a connecting shaft; a shaft body of each connecting shaft is sub-packaged with a beating plate; each beating plate is swung under the driving of a beating plate driving mechanism, so that outer side plates of the plastic plate are respectively blended inwards along the left seamed edge and the right seamed edge of the mold table; the machine frame is provided with a side plate positioning mechanism which can allow the outer side plates to be laminated on the mold table. The bending forming device has the advantages of high work efficiency.

Description

technical field [0001] The invention relates to a bending forming device in a plastic box bending forming machine. Background technique [0002] At this stage, people usually use plastic boxes made of hollow plastic polypropylene materials to ship strip or box-like items such as cigarettes; plastic boxes are surrounded by a whole piece of plastic board, and the structure of the plastic board It is: including the plastic plate body, on the surface of the plastic plate body, there are first indentation lines, second indentation lines and third indentation lines parallel to each other, the first indentation line, the second indentation line The plastic board body is separated into two inner boards and two outer boards by the third creasing line. At present, in the production process of plastic boxes, the plastic sheet is manually bent along its first indentation line, second indentation line, and third indentation line. , not only the labor intensity of workers is high, but a...
