Longitudinal-transverse bidirectional plastic hollow sheet edge sealing machine

Abstract

The invention relates to a longitudinal-transverse bidirectional plastic hollow sheet edge sealing machine which comprises edge sealing devices. Each edge sealing device comprises a working table usedfor containing a PP hollow sheet, a pressing device located above the working table and an edge sealing assembly located on the outer side of the working table. Each pressing device comprises a pressing block used for pressing the PP hollow sheet onto the face of the corresponding working table and a pressing block drive device driving the pressing block to move. Each edge sealing assembly comprises a zipper type edge sealing mold and a mold drive device driving the zipper type edge sealing mold to move along the edge of the PP hollow sheet. The longitudinal-transverse bidirectional plastic hollow sheet edge sealing machine is high in efficiency and good in effect.

Description

technical field [0001] The invention relates to edge banding equipment for PP hollow boards, in particular to a vertical and horizontal two-way plastic hollow board edge banding machine. Background technique [0002] At present, PP hollow board has been widely used in the production of various packaging boxes due to its unique characteristics. Compared with the traditional paper box, the strength of the PP hollow box made of PP hollow board is greatly improved without increasing the weight of the box. In actual production, when using PP hollow boards to make plastic boxes, it is necessary to seal the edges of the PP hollow boards to make the edges smoother, which not only improves the aesthetics of the plastic boxes, but also makes it difficult for users to be caught Cuts on the edges of the plastic box. Existing edge-sealing equipment for PP hollow boards generally can only perform edge-sealing operations on the edges of PP hollow boards parallel to the corrugated ribs, w...

Problems solved by technology

Existing edge-sealing equipment for PP hollow boards generally can only perform edge-sealing operations on the edges of PP hollow boards parallel to the corrugated ribs, while the edges perpendicular to the corrugated ribs, due to their porous cross-section, cannot be Therefore, some manufacturers use small plastic spraying machines to spray molten plastic on the edge of the PP hollow sheet (polypropylenehollow sheet). Although this method can achieve the edge sealing of the edge, but due to The edge is fixed by a plastic spraying machine, and the PP hollow board moves under the plastic spraying machine. When the PP hollow board moves, it is difficult for the plastic sprayed by the plastic spraying machine to spray on its edge evenly, and because part of the molten plastic will fall into the corrugated hole, so the end face is not neat enough, and the plastic is easy to fall off from the plastic PP hollow board after long-term use, and the edge sealing efficiency is also low
