Plastic box bending forming device

Abstract

The invention discloses a plastic box bending forming machine including a machine frame; the machine frame is provided with a mold table, the front end of the mold table is mounted on the machine frame, the rear end of the mold table hangs in the air, and the mold table is provided with a lower knife mold; the machine frame is provided with a mold table top-supporting mechanism and a suction cup cylinder; a piston rod of the suction cup cylinder is provided with a lifting frame; the lifting frame is symmetrically hinged with a pair of suction cup brackets each provided with a suction cup, two groups of suction cups are respectively arranged at two sides of seamed edges of the bottom of the mold table, and the two suction cup brackets are simultaneously hinged with a movable shaft; the machine frame is provided with an outer side plate butt-jointing mechanism which can allow outer side plates of a plastic plate to be in reversed v-shaped butt jointing; a heat lamp can extend into or be far away from an included angle formed by the outer ends of the two outer side plates under the driving of a heat lamp driving mechanism; a part, above the mold table, of the machine frame is provided with a sealing knife lifting cylinder, and a piston rod of the sealing knife lifting cylinder is provided with an upper knife mold; the piston rod of the sealing knife lifting cylinder extends out, so that the upper knife mold and a lower knife mold are in an up-and-down opposite state to make the outer side plates on the lower knife mold laminated mutually; the machine frame is provided with a plastic plate limiting and guiding mechanism. The plastic box bending forming machine has the advantages of high work efficiency.

Description

technical field [0001] The invention relates to a plastic box bending forming device. 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, workers first bend the plastic board along its three indentation lines, and then manually connect the outer ends of the two outer boards in a "human" shape, and then manually use a welding torch to Weld the ...

AI Technical Summary

Problems solved by technology

This kind of operation method of manually bending the plastic plate along its indentation line and manually welding the two outer plates of the plastic plate is not only labor-intensive and low in work efficiency, but also the artificially welded plastic The product welding precision of the box is low, and the defective rate of the plastic box is high
