Description

TECHNICAL FIELD

[0001] The utility model belongs to material weighing distribution technical field, concretely relates to a full -automatic material distribution system of weighing. BACKGROUND

[0002] For the measurement of chemical medicine, the traditional mode is manual electronic scale weighing, but manual weighing has several serious problems. First, for the volatility of chemical medicine, it has a great impact on human health. Some irritating medicines can immediately cause human discomfort, and some odorless medicines can cause chronic poisoning after volatilization. Although the harm can be reduced by using a gas mask and air purification measures, it is still difficult to completely solve this problem. At the same time, in production management, manual weighing also has the problem of uncontrollable precision. For production process control, this is a very unstable factor. Moreover, after weighing, there is no follow-up tracking function, which makes it impossible to further track the cost accounting and process cost reduction and consumption reduction.

[0003] To solve the above problems, a flow metering and conveying device based on electromagnetic flow meter appears in the market, which can continuously measure online according to the material formula, and can be conveyed to the designated site after measurement. This can solve the shortcomings of manual measurement, and the remote conveying function reduces the labor intensity of workers. Combined with the recording function of automatic computer, the measurement data structure can also be well tracked. However, during the use of the flow metering device, there are some serious problems. First, many chemical medicines have low conductivity, unstable detection, and even sometimes undetectable. Second, some chemical medicines have certain adhesion, which can adhere to the electrodes of the flow meter, also causing unstable detection of the flow meter. Third, the premise of flow meter measurement is based on the fixed density of chemical medicine, and there is a gradient distribution of density in the liquid, which will cause uneven site when using electromagnetic measurement. Fourth, the flow meter measurement and conveying are based on all liquids passing through a measurement joint, and the mixing of cationic and anionic drugs will inevitably cause a risk of mixing reaction. If cationic and anionic drugs are transported independently, the cost of equipment will be greatly increased. INVENTION CONTENTS
