Description

Technical Field

[0001] The invention relates to the technical field of equipment for producing a top and bottom lid box, and in particular to a full-automatic forming production line for a top and bottom lid box. Background Art

[0002] The top and bottom lid box is a style of box. The lid of the paper box is the "top" and the bottom is the "bottom", so it is called the top and bottom lid box. It is widely used in various types of hardcover gift boxes, shoe boxes, underwear boxes, shirt boxes, mobile phone boxes and other types of packaging boxes.

[0003] The bottom box of the lid box is mainly made of facial tissue and cardboard. The traditional processing method is to cut off the four sides of a rectangular cardboard to form a right angle, and then cut a V groove along the right angle edge of the cardboard after cutting off the four right angles. During processing, the cardboard is pasted on the facial tissue, and then the four sides of the cardboard are raised, and then the edge of the facial tissue is folded inward onto the inner wall of the cardboard to form a bottom box. Since the four right angles of the cardboard need to be cut off, this bottom box production process leads to a large waste of cardboard materials, increases production costs, and is not environmentally friendly.

[0004] In order to solve the above-mentioned material waste problem, the bottom box can be processed according to the following process, as shown in the attached Fig.14 As shown, it is necessary to prepare a tissue paper 100, a paperboard 101, and two second side panels 102. The tissue paper 100 includes a bottom surface 100a, two first side panels 100b, two second side panels 100c, and four folding ears 100d. The paperboard 101 includes a bottom panel 101a matching the bottom surface 100a, two first side panels 101b matching the first side panels 100b, and two second side panels 102 matching the second side panels 100c. During production, glue is first applied on the top surface of the facial paper 100, and then the cardboard 101 is placed on the top surface of the facial paper 100, the bottom panel 101a and the two first side panels 101b are aligned with the bottom surface 100a and the two first side panels 100b respectively, and then glue is applied on the two side edges of the bottom panel 101a, and then the two second side panels 102 are erected and the bottom ends are bonded to the two side edges of the bottom panel 101a, and then the two first side panels 101b are erected, and the four folding ears 100d are folded inwardly and bonded to the outer surface of the second side panel 102, and then the excess part of the first side surface 100b is folded inwardly and bonded to the inner wall of the first side panel 101b, and then the two second side panels 100c are erected and bonded to the outer wall of the second side panel 102, and then the excess part of the second side surface 100c is folded inwardly and bonded to the inner wall of the second side panel 102, so as to form the bottom box 10. The existing production equipment for lid boxes and bottom boxes is only suitable for the production of bottom boxes using traditional production processes, but not for new production processes. It cannot solve the problem of waste of cardboard materials, resulting in high production costs for bottom boxes, which is not conducive to environmental protection. Related issues need to be solved urgently. Summary of the invention
