AI Technical Summary

Technical Problem

Traditional pneumatic feeding systems lack dynamic metering capabilities, leading to material ratio deviations and cross-contamination. Furthermore, switching raw materials can easily cause pipeline residues and cross-contamination.

Method used

It adopts a material distribution cylinder and a feeding mechanism. The inner cavity of the material cylinder is divided by the dividing mechanism, and the metering feeding is achieved by the telescopic mechanism. The inverted Y-shaped tee pipe design reduces pipe residue. The position of the dividing plate is adjusted by the drive structure, and the feeding pipe is blocked by the telescopic cylinder to achieve independent storage and cleaning.

Benefits of technology

It improves production efficiency, reduces material waste and equipment wear and tear, avoids pipeline residue and cross-contamination caused by frequent raw material switching, and ensures consistent product quality.

Abstract

The utility model provides a plastic feeding mechanism for packaging bag production. The feeding mechanism comprises a material distributing barrel, a separating mechanism and a discharging mechanism. The top of the distributing barrel is open, and a first opening is longitudinally formed in the circle center of the bottom. The separation mechanism enters the material distribution barrel from the opening of the material distribution barrel and equally divides the interior of the material distribution barrel into a plurality of barrel cavities which are transversely and annularly distributed, and the bottom cavity wall of each barrel cavity is sunken from the edge to the middle to form an inner concave face. The discharging mechanism comprises a discharging pipe, a branch pipe and a valve. A communicated blanking pipe is correspondingly arranged at the bottom of each barrel cavity, is positioned in the center of the inner concave surface and longitudinally extends towards the lower part of the material distributing barrel; the branch pipe is obliquely arranged beside the blanking pipe and forms an inverted Y-shaped three-way pipeline with the blanking pipe; and valves are connected to the bottom end parts of the discharging pipe and the branch pipe in a one-to-one correspondence manner. According to the utility model, the production efficiency can be improved, and the material waste possibly caused by frequent switching of raw materials can be reduced; the distance of the discharging pipe is short, and residues of raw materials in the pipeline can be reduced.
