Problems solved by technology

The patent does not mention the problem of gradual aging of the metering pump tube for liquid weighing and the single addition of liquid color masterbatch is very low. It is difficult for the sensor to solve the problem of the material contained in the hopper. The measuring range of the sensor is relatively large, but every time the liquid color masterbatch is added The weight loss is extremely small, so the accuracy of the load cell must be relatively high. It is difficult, or even impossible, to make the load cell have high accuracy and a relatively large measuring range.

Abstract

The invention relates to a weighing liquid color masterbatch and its automatic correction method and application. The weighing liquid color masterbatch includes a liquid color masterbucket, a weighing system, a delivery pump, a support box, a limit alarm device, a touch Display screen, control system and calibration module. The liquid color masterbatch is connected with the delivery pump by a hose. The weighing system, delivery pump, limit alarm device and calibration module are connected with the control system through signal lines. The coordinated design of the weighing system, control system and calibration module enables the automatic calibration weighing liquid color masterbatch machine to realize automatic and precise calibration before production and during the production process, so that the addition of liquid color masterbatch is more accurate, and the produced products have no color difference .

Description

technical field [0001] The invention relates to the processing field of polymer materials, in particular to a weighing type liquid color masterbatch machine for adding liquid additives during the processing of polymer materials and its automatic correction method and application. Background technique [0002] Toner, color masterbatch or other processing aids are often used in the traditional polymer material processing process. Manual weighing and mixing is the method used by most factories with low automation, but the toner will cause dust pollution in this method , while the color masterbatch will absorb moisture during this process to increase the moisture content. With the continuous development of technology, at present, liquid liquid color masterbatches are widely used because of their unique advantages of environmental friendliness, uniform dispersion and easy metering. Compared with the addition ratio of 2%-4% of solid color masterbatch, the addition ratio of liquid...
