Multi-head automatic metering and filling system

Abstract

The invention discloses a multi-head automatic metering and filling system which is mainly composed of a hopper, a quantitative container, an upper insertion board, an upper air cylinder, a lower insertion board and a lower air cylinder. The quantitative container is of a tubular structure, and the upper end and the lower end of the quantitative container are open. The upper port of the quantitative container is formed in discharge ports in one side of the lower end of the hopper. The upper insertion board and the lower insertion board are inserted at the upper port and the lower port of the quantitative container respectively in a penetrating mode. The upper air cylinder and the lower air cylinder drive the upper insertion board and the lower insertion board respectively to move horizontally to open or close the quantitative container. The multi-head automatic metering and filling system further comprises a material supplementary device. By the adoption of the structural mode, the accuracy degree of the discharge ports is + / -3-6.5%. The multi-head automatic metering and filling system has the advantages of being high in filling speed, and the volume for filling each port can be adjusted independently according to production requirements. Particularly, the mode of first-level coarse quantitative filling and the mode of secondary-level high-accuracy rice supplementary quantitative filling are adopted, and the accuracy degree of the multiple discharge ports reaches + / -1-3g when the yield reaches 2000 boxes per hour. The multi-head automatic metering and filling system further has the advantages of being simple in structure, and more convenient to clean and maintain.

Description

technical field [0001] The invention relates to a metering and filling system, in particular to a metering and filling system for producing fresh-keeping rice and adding rice. Background technique [0002] On June 26, 2013, the China Intellectual Property Office published the publication number CN103171777A, and the patent name is an invention patent application document for a household grain automatic filling machine. The patent application includes a grain conveying device, a filling device, a Bag supporting device and sewing device, the filling device includes a funnel; it is characterized in that the filling device also includes a baffle, the funnel has an elongated channel, and the baffle is slidably arranged on the elongated side of the funnel channel, the baffle plate has a state of extending into and withdrawing from the elongated channel, when the baffle plate is extended in, the elongated channel of the funnel is cut off, and when the baffle plate is drawn out, the...

AI Technical Summary

Problems solved by technology

The above-mentioned technical solution is only suitable for the filling of household grain, but cannot be applied to the operation of large-scale assembly line, and the accuracy of the above-mentioned filling is very low

[0003] In addition, the traditional rice filling device uses a multi-head combined electronic scale. This device not only occupies a large area, but also has the problems of slow speed, loud noise, and inconvenient cleaning and maintenance.
