Charging and weighing system and charging and weighing method for cream production line

Abstract

The invention relates to a charging and weighing system for a cream production line. The system comprises a powder material charging and weighing device and a liquid material charging and weighing device; the powder material charging and weighing device comprises powder material storage tanks, a spiral propelling mechanism, a weighing trolley and a variable-frequency motor; the initial end of the spiral propelling mechanism is horizontally and fixedly arranged at the lower part of the powder material storage tank, the variable-frequency motor is used for driving the spiral propelling mechanism; the lower part of the tail end of the spiral propelling mechanism is in butt joint with a feeding hole of the weighing trolley; the weighing trolley is in matched butt joint with a row of corresponding powder material storage tanks above a horizontal track; the weighing trolley is in signal connection with a PLC of the variable-frequency motor, the variable-frequency motor gradually decelerates according to a weighing signal, and the weighing trolley stops rotation after reaching a target weight; the liquid material charging and weighing device comprises liquid material storage tanks and pipeline type mass flowmeters which are connected with each other; and an electromagnetic stop valve is arranged at the tail end of the pipeline of each pipeline type mass flowmeter, and the opening and closing of the electromagnetic stop valve respectively control the operation and stop of liquid material charging.

Description

technical field [0001] The invention relates to an automatic butter production line, in particular to a feeding and weighing system for an automatic butter production line, which belongs to the technical field of butter production lines. Background technique [0002] The production steps of the cream production line include principle storage, ingredients, pasteurization, homogenization, aging, inner packaging (filling), outer packaging, stacking, etc. [0003] In the existing butter production line, during the feeding process of the powder, it is necessary to measure the quality of the feeding. In the prior art, for the feeding of the powder, a weighing device is generally used for weighing. When the powder is fed from the raw material storage bin When it falls into the weighing device, it will generate an impulsive force, and this impulsive force will produce an error for mass measurement. This error is called a dynamic error (the error of the weighing device itself is a st...

AI Technical Summary

Problems solved by technology

[0004] The technical problems to be solved in the present invention are: in the existing butter production line, when the powder is fed, the dynamic error caused by the powder falling from top to bottom into the weighing device is relatively large, and the control of the quality accuracy of the feed is poor; , the mass flowmeter is generally used, and the quality control accuracy is not high, which is unfavorable for the control of product quality
