Description

Technical Field

The efficiency of traditional manual bagging is relatively low, so powder packaging machines are generally used for quantitative bagging of powder products. The operation of weighing the powder and filling the powder into the material box is relatively cumbersome, and there is a problem of dust pollution when filling the powder into the material box, which is time-consuming and laborious, and the work efficiency is low.

[0003] In order to solve the problems existing in the prior art, the utility model with technical publication number: CN202321409089.8 discloses a powder filling machine (hereinafter referred to as: prior art 1), including: a frame, with a supporting platform for supporting a bag body and a column located on the rear side of the supporting platform; a lower hopper connected to the front side of the column and arranged corresponding to the upper and lower sides of the supporting platform, and a cover plate is provided on the top of the lower hopper; two negative pressure adsorption heads are arranged on the supporting platform and are respectively arranged close to the front and rear side edges of the supporting platform, and the negative pressure adsorption heads are used to adsorb the front and rear side walls of the bag body; two bag supporting assemblies are slidably connected to the supporting platform and are respectively arranged close to the left and right side edges of the supporting platform, and the bag supporting assembly has a supporting arc arm that can move downward and support the inner wall of the bag body.
