Method for automatically adjusting extruded rubber blank and controlling extrusion blow molding based on three-dimensional (3D) scanning

Abstract

The invention belongs to the field of blow molding production, and in particular relates to a method for automatically adjusting extruded rubber blank and controlling extrusion blow molding based on three-dimensional (3D) scanning. The method comprises the steps of scanning a 3D model or 3D drawing for inputting; automatically selecting an appropriate flow rubber head and determining a flow rubbercurve; automatically mixing raw materials, checking feedback and automatically adjusting the proportion of masterbatch; carrying out electromagnetic induction heating, adjusting the flexible neck-direction and axial wall thicknesses of a mold blank, monitoring the wall thicknesses of the mold blank and feeding back, and automatically adjusting the wall thicknesses of the mold blank; carrying outa blow molding process according to preset process parameters, automatically adjusting blow molding pressure and gas volume, controlling mold temperature, mold opening and closing speed and cycle, andautomatically correcting the size, wall thicknesses and the like of blow molding equipment so as to realize the closed-loop automatic control. The method provided by the invention has the beneficialeffects that operation is adjusted based on a continuous and automatic process without needing any manual intervention, the raw materials in a container are accurately allocated, online wall thicknessmeasurement feedback is monitored in real time, and the wall thicknesses of the mold blank is automatically adjusted, so that the product wall thickness distribution is enabled to be more uniform, and the quality of the hollow container is improved.

Description

technical field [0001] The invention belongs to the field of blow molding production, and in particular relates to a method for automatically adjusting and controlling extrusion blow molding of extrusion rubber blanks based on 3D scanning. 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. The industry is constantly pursuing the ultim...
