Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of plastic internal mixer, specifically relates to a falling type plastic internal mixer with automatic cleaning function. BACKGROUND

[0002] The plastic internal mixer is a kind of equipment widely used in plastic, rubber, chemical and other fields, and its main function is to process various materials into required plastic or rubber products by mixing and kneading etc.In the working process of the plastic internal mixer, materials enter from the upper part and are mixed and kneaded in the internal mixer chamber by falling mode.In order to ensure that the materials are fully mixed and avoid residues, a scraper is generally arranged at the discharge plate to clean the residual materials attached to the discharge plate during falling.

[0003] The existing plastic internal mixer usually only sets a single scraper on the discharge plate, and the scraper is cleaned by keeping a certain distance from the discharge plate in a fixed manner.In actual operation, due to different material properties and different material accumulation conditions during discharging, the scraper with fixed distance may cause two extreme situations: one is that the distance between the scraper and the discharge plate is too small, which causes too much material to be scraped at one time, causing material accumulation and affecting subsequent operation, and the other is that the distance between the scraper and the discharge plate is too large, which causes the scraper to be unable to effectively clean the residual materials, therefore, we design a falling type plastic internal mixer with automatic cleaning function to provide another technical solution for the above technical problems.
