AI Technical Summary
Traditional mixing equipment used in plastic film production has low mixing efficiency when adding raw materials, especially since the initial mixing tank has a limited capacity, resulting in some raw materials not being mixed in time.
A mixing device comprising a stirring shaft, a stirring rod, a spiral conveyor blade, and a stirring blade is designed. The stirring shaft is driven to rotate by a stirring motor to achieve preliminary and secondary mixing of raw materials. The spiral conveyor blade and the guide plate are used to disperse the raw materials, and the mixing efficiency is improved by combining the stirring action of the stirring blade.
This process enables secondary premixing of raw materials during the addition process, significantly improving mixing efficiency and ensuring that all raw materials can participate in thorough mixing.

[0010] Further, the stirring rod is divided into upper, middle and lower three layers, and the scraper is fixedly connected between the upper stirring rod and the middle stirring rod and between the middle stirring rod and the lower stirring rod.
[0011] Working principle and process:
[0012] In use, the stirring motor is actuated to drive the stirring shaft to rotate, thereby driving the stirring rod, the spiral conveying blade and the stirring blade to rotate. The number of the feeding ports is set according to the types of the required raw materials. The raw materials are added into the feeding hopper through the feeding ports. The stirring rod preliminarily stirs and mixes the raw materials in the feeding hopper. The scraper prevents the raw materials from sticking to the inner side wall of the feeding hopper. The preliminarily mixed raw materials fall into the discharge port and are then conveyed into the tank body by the spiral conveying blade. Part of the raw materials directly falls into the bottom of the tank body, and the other part of the raw materials falls on the guide disc and then falls on a position closer to the side wall of the tank body through the guide of the guide disc, so that the secondary mixing of the raw materials is realized through the dispersion of the raw materials.
