Carton cracking-proof line spraying system

Abstract

The invention discloses a carton cracking-proof line spraying system. The carton cracking-proof line spraying system comprises a steam manufacturing device, a main pipeline for conveying steam, a flowopening and closing valve for opening and closing steam, a main control mechanism for controlling the steam flow pressure and an injection assembly for spraying steam; the carton cracking-proof linespraying system structurally comprises a steam manufacturing device and a conveying pipeline for conveying steam, a steam nozzle is mounted on the conveying pipeline, the steam is sprayed through thesteam nozzle and runs through a slot pressing line position on a corrugated paper, so that the original paper fiber at a folding position is softened, and the situation of cracking and breaking is avoided during folding. The pressing line is flat, a forming line is a straight line, the condition that a scissor opening is formed when the box is sealed is avoided, the generation of condensed water when the condensed water is sprayed to the carton corrugated paper is avoided by controlling the steam temperature and pressure in the main pipe and the steam temperature and pressure in the steam nozzle, the quality of the finished product of the carton is improved, and the overall production cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of carton corrugated cardboard processing, in particular to a carton explosion-proof line spray system. Background technique

[0002] With the development of society, most of the current commodities are packaged in printed cartons, and cartons are generally made of corrugated cardboard by folding, slotting is processed at the folded part of the carton, and a slotting line is pressed along the slot. Due to dry weather and other reasons during the folding process of the carton, the folding endurance of the base paper fibers on the slotting line in the carton is reduced (reduced paper quality), resulting in the bursting of the carton surface paper and inner paper (forming line) during the folding process. In addition, due to the poor formation of the carton, there are irregular left and right bulges on the crease line, and the forming line forms an S-shaped situation, resulting in poor carton formation, low pas...
