Description

Technical Field

[0001] The invention relates to the technical field of paper box production equipment, in particular to a three-grid three-dimensional T-shaped box forming equipment. Background Art

[0002] At present, there are two types of paper box forming technologies on the market. One is three-dimensional gluing forming, which has the advantages of high efficiency, low production cost and convenience for large-scale production. The disadvantage is that due to the use of "glue" for bonding, there are certain environmentally unfriendly requirements, and the product stability is poor and it is easy to open the glue. The other is the hot bonding principle for bonding forming, which has the advantages of environmental protection, stability and beauty. The disadvantage of the hot bonding forming method is that during the forming process, the paper sheets are heated by the hot forming mold using multiple high-power heating tubes, which makes the energy consumption of the entire machine high. In the forming process, due to the high temperature of hot bonding, some printed products may be discolored or changed, seriously affecting the appearance and quality. In addition, the current paper boxes are bonded and separated by patching, and there are often problems such as loose bonding and misaligned bonding, which leads to leakage of soup.
