Description

technical field [0001] The invention relates to a honeycomb paperboard forming process. Background technique [0002] Honeycomb paperboard is a widely used packaging material. There are many production methods in the prior art, such as: 1. The vertical gluing production process of honeycomb paperboard, which is composed of three processes, namely: 1. Honeycomb rolling process: Upper paper roll (two rolls or multiple rolls of paper) → glue vertically → roll into a honeycomb paper core → stop and remove the honeycomb paper core → press the oil press to compact the honeycomb paper core → take out the honeycomb paper core and dry 2. Paper core connection process : The paper cutter cuts out the core paper according to the specifications → coats the glue line for connection → connects the honeycomb paper core → takes out the connected honeycomb paper core and dries it. It consists of three processes, namely: 1. Honeycomb making process, upper flat paper → horizontal glue line → d...

AI Technical Summary

Problems solved by technology

[0003] Deficiencies in the existing technology 1. Deficiencies in the vertical gluing process of honeycomb paperboard: ①It must be shut down between processes, so continuous production cannot be formed, resulting in low production efficiency; ③Due to the closed sides of the rolled honeycomb paper core, the internal stress of the paper core cannot be released during the compaction process, resulting in uneven surfaces on both sides of the paper core and weak bonding of the paper core (paper and between the papers) is easy to disengage, and the closed ends of the paper core have no use in actual use but must be cut off, resulting in a large material loss

④The honeycomb paper core must be bonded together after being cut into paper core strips. Due to the inaccurate dislocation of the glue line when it is bonded again, the honeycomb structure of the joint part has a large deviation, which affects the quality of the board

2. Deficiencies in the production process of honeycomb paperboard horizontal gluing: because the horizontal gluing uses flat paper, the two ends of the paper core are open when it is made, which solves the internal stress release problem of the paper core during the compaction process, but The problems existing in other vertical gluing production processes have not been solved
