Human-computer interaction intelligent closed-loop control method of full-automatic blow-molding production line and process thereof

Abstract

The invention belongs to the field of blow-molding production and particularly relates to a human-computer interaction intelligent closed-loop control method of a full-automatic blow-molding production line and a process thereof. The method successively comprises the following steps: scanning and inputting a 3D bottle shape or a 3D drawing; selecting a suitable flow glue head and determining a flow glue curve; automatically mixing materials, checking and feeding color difference on line and automatically adjusting a color masterbatch ratio; carrying out electromagnetic induction heating, flexibly adjusting the thickness of the radial wall and the axial wall of an extrusion blank, monitoring and feeding the wall thickness of the blank, and enabling the wall thickness of the products to be more uniformly distributed; carrying out a blow molding process by checking and feeding the appearance and the cutting quality on line; automatically removing burrs, measuring the size of bottle openings and bottle bodies on line, testing leakage on line, labeling on line, shooting video on line and finally automatically stacking and packing through a packing machine. The method has the beneficialeffects that the operation is based on lasting and automatic process adjustment; the manual intervention is not needed; hollow container raw materials are accurately distributed; the products are monitored in real time and are measured and fed back; the process is automatically adjusted; the products are in dynamic and continuous adjustment state and continuously tend to be standard samples; the quality of hollow containers is improved; the production of waste products is reduced or avoided; the passive situation of established fact caused by post detection can be completely changed; the method is capable of achieving online detection and closed-loop feedback and adjusting at first time; the ideal state with early prediction, process control and high-quality production can be really achieved.

Description

technical field [0001] The invention belongs to the field of blow molding production, and in particular relates to a human-computer interaction intelligent closed-loop control full-automatic blow molding production line and technology. Background technique [0002] Extrusion blow molding is mainly used for unsupported parison processing. It has high production efficiency, low equipment cost, and a wide range of molds and machinery. The disadvantages are high scrap rate, poor recycling and utilization of waste, product thickness control, The dispersion of raw materials is limited, and the quality control of hollow containers usually relies on frequent sampling and laboratory tests, and then manually adjusts them according to the test results. This process not only takes a long time, greatly reduces the efficiency of the production line, but also cannot completely guarantee the hollow The containers all met the specifications. [0003] The quality control of non-hollow contai...
