Corner-sticking-free mold-free lid and base box forming mechanism

Abstract

The invention discloses a corner-sticking-free mold-free lid and base box forming mechanism. the mechanism comprises a conveying device, a gluing device, a lower side plate device, a positioning and ear folding device and a surface paper erecting device, wherein the lower side plate device is positioned above the conveying device, and the surface paper erecting device is positioned below the conveying device; the lower side plate device comprises a side plate mechanism, a side plate pressing down mechanism and a side plate guide mechanism, the side plate mechanism comprises a bearing plate anda push plate, the bearing plate is used for bearing side plates, the push plate is used for pushing the side plates to the side plate pressing down mechanism, and the side plate pressing down mechanism presses the side plates along the side plate guide mechanism to the front end and the rear end of a paper plate; the positioning and ear folding device comprises a positioning rod and an ear folding part, and is used for folding dog-ears on the surface paper; and the surface paper erecting device is used for erecting the surface paper on the periphery of a paper board. The mechanism is simple in overall structure, free of corner sticking, free of mold, capable of automatically positioning the side plates, capable of greatly reducing the production cost, high in automation degree, high in processing efficiency, high in bonding fastness and wide in application range.

Description

technical field [0001] The invention relates to the technical field of heaven and earth cover boxes, in particular to a forming mechanism for a world cover box free of pasting corners and molds. Background technique [0002] Tiandi Gai Box refers to a style of box. The cover of the carton is "Heaven" and the bottom is "Earth", so it is called Tiandi cover box, which is widely used in various hardcover gift boxes, shoe boxes, underwear boxes, shirt boxes, mobile phone boxes and other packaging boxes. [0003] The heaven and earth cover box is made by bonding facial paper and cardboard. First, the facial paper is evenly coated with glue, and then the cardboard is placed on the upper end of the facial paper, and the edges are folded and pressed together. Before the above-mentioned forming process, the processing of the traditional heaven and earth cover box first needs to cut the face paper and cardboard. The cut cardboard and face paper each have a bottom plate, four side pla...

Problems solved by technology

[0004] After printing and cutting the corners of the traditional Tiandi cover box, it still needs to rely on manual or semi-manual auxiliary equipment to complete the lamination of single corners with glue (the four corners need to be pasted four times in total), that is, the glue pasting process. The production efficiency is low, and the unit labor efficiency is low; at the same time, because the traditional process needs to cut the cardboard, except for the side panels, bottom panels and corners, the rest of the cuts become waste, resulting in an increase in production costs; In addition, The processing technology of the traditional world cover box also has the defects of low bonding fastness and easy damage, especially for large-scale world cover boxes that need to be processed by jigsaw panels, the disadvantage of low fastness is very obvious; again, the traditional world cover box Processing, every time the model is changed, it is necessary to re-adjust the cutting process mold and glue pasting process, the degree of automation is low, and the processing efficiency is low
