A molding processing process for manufacturing a molded packaging box

Abstract

The present invention relates to a manufacturing and shaping process of molded packaging boxes, in particular to an auxiliary device for manufacturing and shaping processing of molded packaging boxes, which includes a rotating tray mechanism, an adjusting drive mechanism, an adjusting transmission mechanism, and a shaping inner bracket. The tray mechanism includes a rotatable disc-shaped primary tray, the adjustment driving mechanism is arranged on the bottom end of the primary tray to rotate with it, and the adjustment transmission mechanism is arranged on the upper surface of the primary tray to follow it. Rotation; the device involved in the treatment process provided by the present invention can assist in drying the frustum-shaped pulp molded packaging box in the drying process, and can prevent the pulp molded packaging box from being deformed after drying and setting through effective internal support. In addition, rotary drying is used The method can achieve uniform drying, and greatly speed up the drying rate.

Description

technical field [0001] The invention relates to the technical field of packaging material production, and specifically proposes a shaping process for manufacturing a molded packaging box. Background technique [0002] Pulp molded packaging boxes are made of pulp materials and processed by mold molding. Because the materials are degradable, they are more environmentally friendly than plastic packaging boxes and have been widely used in the field of product packaging; pulp molded packaging boxes are used in the production process. Pulp as the raw material is mainly processed through two process steps: molding and drying. Therefore, after the molding is completed, it is necessary to further dry and shape. In the traditional drying and shaping process, there are mainly the following problems. : [0003] 1) The pulp molded packaging box to be dried is generally dried in a centralized manner, but due to the failure of effective shaping support, it will cause a certain degree of d...

AI Technical Summary

Problems solved by technology

[0003] 1) The pulp molded packaging box to be dried is generally dried in a concentrated manner, but due to the failure of effective shaping support, a certain degree of deformation occurs after drying, thus affecting the quality of the final shaped pulp molded packaging box ;

[0004] 2) In the drying process, the static drying method is often used for drying treatment, and the heat source is generally unevenly distributed in the drying space, thus affecting the drying rate of all packaging boxes
