Automatic up-and-bottom cover box integration molding machine

Abstract

The invention discloses an automatic up-and-bottom cover box integration molding machine which comprises a rack. A conveying device, a gluing device, a paperboard covering device, a laminating device, a first edge folding device and a press-fitting device are sequentially arranged on the rack from left to right. The gluing device is used for coating a glue on the upper layer of surface paper; the paperboard covering device and the laminating device are used for laminating a paperboard and the surface paper; the first edge folding device comprises a glue dispensing device, a lower side plate device, a positioning and lug-folding device and a surface paper standing device so as to be used for placing side plates at the front end and the back end of the paperboard, automatically positioning the side plates onto the paperboard, and standing surface paper on the periphery of the paperboard; and the press-fitting device comprises a second edge folding device and a bubble pressing device so as to be used for inwards press-fitting the surface paper and carrying out bubble pressing treatment on an up-and-bottom cover box. The automatic up-and-bottom cover box integration molding machine provided by the invention is simple in overall structure, only two side plates need to be cut, corner gluing and a mold are not needed, automatic edge folding and bubble pressing are realized, the production cost is greatly reduced, the automation degree is high, the processing efficiency is high, the bonding firmness is high, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of space and earth cover boxes, in particular to an automatic space and ground cover box integrated molding machine. 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 of tissue paper and cardboard. First, the tissue paper is evenly coated with glue, and then the cardboard is placed on the upper end of the tissue 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 plates and four folde...

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 a great increase in production costs; traditional The processing technology of the world cover box still has the defects of low adhesion fastness and easy damage, especially for large-scale world cover boxes that need to be processed by jigsaw puzzles, the defect of low fastness is very obvious; the traditional world cover box processing, When the face paper is erected, it needs the assistance of the mold to complete it, and every time the model is changed, it is necessary to re-adjust the parameters of the cutting process mold and glue sticking process, the degree of automation is low, and the processing efficiency is low

[0005] In order to avoid air bubbles, the traditional world cover box pressing process is carried out in a semi-manual processing mode. During pressing, the positioning plate is used to position the world cover box, and the position of the side plate of the world cover box relative to the positioning plate is manually adjusted. , manually bend the face paper inward, and use the pressing part to press the face paper to the side plate. This method is time-consuming, laborious, low in automation, and low in processing efficiency. Moreover, when the model of the cover box changes, the above The parameters of the process also need to be readjusted, which is time-consuming and laborious, and the production efficiency is low; in addition, in the prior art, there is no bubble-pressing process, resulting in air bubbles at the bottom of the world cover box after the pressing is completed, which affects product quality and is not beautiful
