10. The method for three-dimensional kneading of a multi-component resin, which comprises the following steps:
1) And (3) multi-element resin vacuum feeding treatment: according to the production condition, pouring the multi-element resin material into powder unloading equipment such as a small bag feeding station and a ton bag bale breaker, starting vacuum conveying equipment, generating negative pressure airflow formed by high vacuum by a vacuum generating facility, conveying the material into an equipment cylinder, blocking the material in the powder conveying equipment cylinder by a filter, and ensuring that the material cannot enter a vacuum pump;
2) Automatic metering treatment of multi-element resin: the method comprises the steps that automatic weighing treatment is carried out on the multi-element resin materials through a weighing module in a weighing and metering tank, and after the weighing treatment is finished, the multi-element resin materials in the weighing and metering tank are evenly and accurately discharged through a screw feeding system according to a preset value;
3) Premixing the multi-element resin: premixing a multi-element resin material through the cooperation among a high-speed mixer (1), a main feeder (2) and a lateral auxiliary feeder (3), and feeding from a first screw cylinder and a sixth screw cylinder respectively after premixing;
4) Twin-screw melt mixing: the screw is driven to rotate by the speed reducing variable frequency motor, so that the material is pushed to move forwards, and the conveying capacity is ensured by the stroke, the diameter and the rotating speed of the screw;
5) Underwater pelletizing treatment of the multi-component resin: granulating the melted and mixed materials by an underwater granulator;
6) And (3) multi-element resin screening treatment: conveying the multi-element resin particles subjected to grain cutting into a vibrating screen, and vibrating and screening the multi-element resin particles through the vibrating screen;
7) And (3) storing the multi-element resin: conveying the multi-element resin particles after screening to a finished product bin for storage through a mud pump;
8) And (3) multi-element resin vacuum feeding and packaging treatment: and (5) carrying out vacuum feeding packaging on the multi-element resin particles in the finished product bin according to packaging requirements.
