Description

Quantitative weighing hopper scale

Technical Field

The invention relates to the technical field of weighing scales, in particular to a quantitative weighing hopper scale.

Background

In the process of weighing and packaging, strict weight regulations are provided for raw materials, and once too much or too little assembly occurs, the effect of a product or some problems of packaging can be influenced, so that strict control on the weight of the materials is required.

However, most of the existing weighing structures are complex in structure, cannot be well weighed and can accurately weigh.

Therefore, a quantitative weighing hopper scale is in urgent need of research.

Disclosure of Invention

In order to comprehensively solve the problems, particularly the defects in the prior art, the invention provides a quantitative weighing hopper scale which can comprehensively solve the problems.

In order to achieve the purpose, the invention adopts the following technical means:

the utility model provides a quantitative weighing hopper scale, includes hopper scale support, be provided with the hopper on the hopper scale support, hopper upper portion is provided with straight tube portion, the lower part of hopper is provided with down straight tube portion, upward be provided with first electric butterfly valve in the straight tube portion, be provided with second electric butterfly valve in the straight tube portion down, it stretches into inside the hopper to go up straight tube portion, the discharge end correspondence of going up straight tube portion is provided with the take-up (stock) pan, the take-up (stock) pan passes through bearing sensor and is connected with the fixed plate, the fixed plate lower part is provided with the support frame, the support frame is fixed on the rotation axis, the rotation axis is through setting up the rotating electrical machines drive in the hopper.

Furthermore, a plurality of buffer springs are arranged between the material receiving disc and the fixing plate.

The beneficial effects are that, be favorable to better buffering the power that the charging tray gave the fixed plate, increase the life of fixed plate.

Furthermore, the support frame adopts the triangle-shaped structure setting.

The beneficial effects are that, be favorable to better support fixed plate.

Furthermore, a flaring material receiving port is arranged at the upper part of the upper straight pipe part.

The beneficial effects are that, be favorable to better carrying out the feeding.

The invention has the beneficial effects that: the material receiving tray is simple in structure, feeding can be carried out from the upper straight pipe part, feeding materials enter the material receiving tray along the upper straight pipe part, the material receiving tray is in contact with the weighing sensor, the weight of the feeding materials can be detected, the material receiving tray is inclined through the rotating motor, the weighed feeding materials are poured into the hopper and are repeatedly weighed, when the required weight is achieved, the first electric butterfly valve is closed, the second electric butterfly valve is opened to carry out material discharging, quantitative material discharging can be better achieved, and weighing is more accurate.
