AI Technical Summary
In PPR pipe production, when changing to different colors, the feed screw cannot reach the feed port during the raw material change process, resulting in raw material residue between the meter weight control system and the barrel. This causes problems such as long washing time, more scrap, and high production costs.
Design a device that includes a main unit, a meter-weight control system, a barrel, a suction feeder, and a steel wire hose. The steel wire hose is connected to the meter-weight control system and a vacuum pump. The vacuum pump is used to create negative pressure to quickly suck out the excess material between the feed inlet and the barrel, reducing material waste.
It enables rapid recovery of screw raw materials, shortens start-up time, reduces raw material waste, lowers production costs, and improves production efficiency.
