Embodiment Construction

[0032] like figure 1 As shown, the present invention introduces a fully automatic feeding system for a polymer extruder, including a high material level sensor 1, an agitator 2, a low material level sensor 3, a star discharge valve 4, and a material conveyor No. 5 , pressure sensor 11; high material level sensor 6, low material level sensor 7, material conveyor II No. 8, laser scanner 9, scroll plate 10, programmable computer control system 12.

[0033] like figure 1 As shown, the storage silo can store 7-day consumption materials. There is a three-stage stirring device 2 in the storage silo. When the machine is running, the agitator starts the first-stage arc agitator and the second-stage arc agitator according to the amount of material. The device and the class III arc agitator ensure that the materials are always mixed evenly in the storage silo and the feed silo. The storage silo body is equipped with a high material level sensor 1 and a low material level sensor 3. When th...

Abstract

The invention relates to a full-automatic feeding system of a polymer extruder machine, and particularly relates to a full-automatic feeding mechanism capable of preventing blockage, achieving automatic speed regulation and uniformly mixing materials. The full-automatic feeding mechanism mainly comprises a material conveyor I, a material conveyor II, an upper whorl plate and whorl stir pieces arranged above a stirring mechanism in design, upper material position sensors and lower material position sensors arranged on a material storage bin, a feeding bin, and pressure sensors arranged on the stock bins, wherein the sensors are controlled by a programmable computer control system; and a material accumulation rate (namely the ratio of the volume of the material to the volume of the compartment) is monitored by the laser scanning device on the material conveyor I, wherein the laser scanning device is controlled by the programmable computer control system to feeding stably. By means of thestructure, the materials can automatically enter the extruder machine smoothly, and the materials can be uniformly mixed in the whole process.

Description

technical field [0001] The present invention relates to a polymer extrusion machine. In particular it concerns the feed system of polylactic acid (PLA) extruders. Background technique [0002] The feeding mechanism of the existing extruder uses a screw to convey the polylactic acid (PLA) mixture, which is easy to block; due to the smooth surface of the granular PLA, it is easy to slip in the gap when the screw conveyor is conveying, and the material stagnates. Dealing with material clogging is time-consuming and labor-intensive, seriously reducing production efficiency and productivity. [0003] The feeding mechanism of the traditional extruder requires manual timing feeding, which has a low degree of automation, increases labor costs, and is laborious. At the same time, the existing screw conveyor controls the feeding amount according to the speed of the screw. When the feeding amount becomes larger after manual feeding, it is easy to block the pipeline; when the feeding ...
