Automatic carton folding production line

Abstract

The invention provides an automatic carton folding production line and relates to an improvement in the structure of the automatic carton folding production line. The automatic carton folding production line provided by the invention has the advantages that the reliability is high, the degree of automation is high, and the product quality is guaranteed. The automatic carton folding production line comprises a carton folding-forming mechanism, and is characterized in that a carton raw-material cardboard automatic detecting device is arranged at the front end of the carton folding-forming mechanism; a rolling mechanism is arranged at the rear end of the carton folding-forming mechanism; the carton folding-forming mechanism comprises a conveying belt; and a left folding belt and a right folding belt are arranged on the conveying belt. The carton folding-forming mechanism is characterized in that a front mounting frame, a middle supporting frame and a rear mounting frame are arranged above the conveying belt; the tail end of the left folding belt is arranged on the middle supporting frame; a left pressing rod corresponding to the left folding belt is arranged on the front mounting frame; a gluing nozzle is arranged at the position, corresponding to the tail end of the left folding belt, above the conveying belt; a drying air duct is arranged at the back of the gluing nozzle; and the rear mounting frame is connected with the tail end of the right folding belt.

Description

technical field [0001] The invention relates to an improvement of the structure of a carton automatic folding production line. Background technique [0002] The production of packaging boxes is made by cutting raw materials into specific shapes, then folding them through folding equipment, and then forming them. Since the raw cardboard is occasionally damaged during the production, transportation, and cutting process, if the damaged packaging box flows into the later process, it may cause jamming of the equipment or produce defective products. This situation hinders the automatic production rhythm of the packaging box and reduces production efficiency. [0003] At present, in the existing packaging box folding equipment on the market, the cut raw cardboard is usually folded from both sides at the same time; due to the hardness and elasticity of the raw cardboard in this folding method, it is easy to cause the raw cardboard on both sides to overlap.

AI Technical Summary

Problems solved by technology

[0003] At present, in the existing packaging box folding equipment on the market, the cut raw cardboard is usually folded from both sides at the same time; due to the hardness and elasticity of the raw cardboard in this folding method, it is easy to cause the raw cardboard on both sides to overlap. The problem of interference; if the production tempo is too fast, it is easy to cause problems such as stuttering

[0004] In addition, some raw cardboards need to be glued to the fold; if both sides are folded at the same time, it will affect the glue

[0005] Moreover, if the glue is pressed immediately after applying the glue, it may cause glue overflow. The overflow glue will pollute the surface of the carton, resulting in an increase in the scrap rate and affecting product quality.
