Feeding device and feeding method

Abstract

The invention discloses a feeding device. The feeding device comprises a base, a vacuum feeding machine arranged on the base and a connecting pipe, a weighing component is arranged on the base, a material container is arranged on the weighing component, a first breather valve and a first connecting joint are arranged at one end of the connecting pipe, a second breather valve and a second connecting joint are arranged at the other end of the connecting pipe, and a discharging port of the material container is connected with the first connecting joint. The vacuum feeding machine is connected with the second connecting joint through a feeding pipe. The feeding method comprises the steps that S1, feeding is conducted through the vacuum feeding machine, specifically, S1.1, the discharging port of the material container and the first breather valve are opened, the second breather valve is closed, the vacuum feeding machine is started, and materials in the material container enter the vacuum feeding machine through the feeding pipe; and S2.2, when the weight measured by the weighing component is reduced to a set value, the discharging port of the material container and the first breather valve are closed, the second breather valve is opened, and the materials in the feeding pipe enter the vacuum feeding machine. The feeding device is simple in structure, high in automation degree and beneficial to accurate control over the feeding amount.

Description

technical field [0001] The invention relates to food and medicine packaging machinery and equipment and usage methods, in particular to a feeding device and a feeding method. Background technique [0002] At present, the general feeding method is to weigh according to the demand first, and then transfer the weighed material to the container that needs to be fed through the feeding hopper. The degree of automation is low and the operation is cumbersome, especially when the amount of feeding is large. When the feeding container is far away, it takes time and effort. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a feeding device with simple structure, high degree of automation, and accurate control of feeding amount. [0004] The present invention further provides a feeding method for the above feeding device. [0005] In order to solve the problems of the technolo...
