Abstract

The invention relates to forming equipment of PLA dual spraying film paper tableware. The forming equipment comprises a rack and a bottom heater arranged at the bottom of the rack. The bottom heater comprises a heating furnace mold. A hot air blowing mold is mounted in the heating furnace mold and is provided with air blowing holes, and the air blowing holes are arranged obliquely. The included angle formed by the center axis of each air blowing hole and the longitudinal straight line is an oblique angle. According to the forming equipment, the hot air blowing mold structure of the bottom hotair heater is changed, the air blowing holes of the hot air blowing mold are arranged obliquely, the oblique angle of each air blowing hole is set to be 30 degrees + / - 2 degrees, meanwhile, the hole diameter of each air blowing hole is set to be 0.8 mm, and therefore the air blowing area of the bottom hot air heater to the cup bottom is changed; and the phenomena of layering, blistering and the like caused by the situation that the bottom hot air heater blows a cup body are avoided, and the quality of the PLA dual spraying film paper tableware is guaranteed.

Description

technical field

[0001] The invention relates to the field of paper tableware processing equipment, in particular to molding equipment for PLA double-coated paper tableware. Background technique

[0002] Paper cup forming equipment is a kind of processing equipment that processes the cup body and cup bottom of paper cups at the same time, and then combines the cup body and cup bottom.

[0003] The current paper cup forming equipment is mainly used to produce PE paper cups and single PLA paper cups, and there is no forming equipment for paper tableware such as PLA double-coated paper cups. If the molding equipment for PE paper cups or the molding equipment for single PLA paper cups is used to produce PLA double-coated paper cups, the quality of the produced PLA double-coated paper cups is very poor and cannot be used normally.

[0004] In view of this, the inventor aimed at the many defects and inconveniences caused by the imperfection of the above-mentioned PLA double-coated...
