Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a granule quantitative weighing and packaging machine. Background Technology

[0002] In the process of packaging granules, the packaging drum can be placed above the weighing plate of the packaging machine, and the weighing plate then packages the granules to a fixed weight. However, in existing packaging machines, due to the squeezing between granules and the mechanical transmission during filling, the edges of the granules break, resulting in a certain amount of powder inside the feeding drum. This powder entering the packaging drum can easily affect product quality. Furthermore, it is difficult to position the packaging drum during packaging, which can easily cause granules to fall onto the weighing plate, resulting in material waste. Therefore, improvements to the existing technology are needed. Utility Model Content

[0003] The purpose of this invention is to provide a quantitative weighing and packaging machine for granules, which solves the problems of powder affecting product quality and the inconvenience of positioning the packaging barrel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a granule quantitative weighing and packaging machine, comprising a base, a weighing device fixedly connected inside the base, a weighing plate provided at the upper end of the weighing device, a packaging barrel placed at the upper end of the weighing plate, a positioning mechanism provided at the upper end of the weighing plate, a frame fixedly installed on the outer back of the base, a feeding barrel fixedly connected inside the upper end of the frame, a barrel cover connected to the upper end of the feeding barrel by a thread, a screening barrel slidably connected inside the feeding barrel, multiple evenly distributed filter screens fixedly connected to the outer inclined surface of the screening barrel, a guide ring fixedly connected to the inner bottom of the screening barrel, a main shaft installed inside the barrel cover by a bearing, a stirring frame fixedly connected to the outer side of the main shaft, and a reamer fixedly connected to the lower outer part of the main shaft.
