Accurate weighing type packaging machine system and filling method

Abstract

The invention discloses an accurate weighing type packaging machine system and a filling method, which solves the technical problem of accurately filling materials in a material packaging process, and makes a material filling quantity be possibly close to a standardized weight, so as to make the material filling quantity achieve an allowed error range through at least two filling processes; a filling mechanism structure of a packaging bag comprises at least two material filling machines; a sub-packaging quantity monitoring device is arranged between the two material filling machines, the packaging bag is located; the former-stage material filling machine conveys the filled packaging bag to the sub-packaging quantity monitoring device to weight, and conveys the packaging bag to the next-stage material filling machine to refill after feeding back information, and finally conveys the refilled packaging bag to a sub-package post-processing mechanism until weight precision of the materials in the packaging bag achieves the allowed error range of the design.

Description

technical field [0001] The invention relates to a prefabricated bag weighing type automatic packaging machine, especially a packaging machine system and a filling method capable of accurately filling materials, which can be widely used for packaging powdery materials, paste materials or liquid materials, especially for pesticides During the packaging of preparations. Background technique [0002] At present, there are many types of packaging machines used in the pesticide industry. The structural types can be divided into vertical, horizontal, linear, rotary, etc. The bag making methods include self-made bags and prefabricated bags. Volumetric packaging machines are generally used. High fineness, strong adhesion, poor dispersibility, poisonous and smelly, difficult to package, so the powder will often stick to the filling equipment during the filling process, resulting in inaccurate quality of the filled material, which will eventually bring come to trouble. For the manufa...
