Description

Butyl cement production raw material mixing and stirring mechanism

Technical Field

The utility model relates to the technical field of raw material stirring mechanisms, in particular to a raw material mixing and stirring mechanism for butyl cement production.

Background Art

Butyl putty, also known as butyl tape, is an environmentally friendly sealing material. It is made by blending butyl rubber, polyisobutylene and other main polymer raw materials. Butyl putty has the advantages of weather resistance, heat resistance, acid and alkali resistance, etc. Usually, in the production process of butyl putty, it is necessary to mix and stir multiple raw materials through a mixing and stirring mechanism. However, when the traditional mixing and stirring mechanism is used, some raw materials adhering to the inner wall of the mixing tank are difficult to be stirred, which will affect the mixing uniformity of the raw materials and is not convenient for people to clean later.

In order to address the above problems, a Chinese patent with an existing announcement number of CN217962130U proposes a mixing and stirring mechanism for raw materials for butyl cement production. The device drives a stirring rod and a stirring blade to stir the raw materials in a mixing drum through a stirring motor, and at the same time drives a driving wheel to rotate, and then through the transmission of a transmission belt, the threaded screw on the driven wheel can be driven to rotate, so that the sliding nut can move along the outside of the threaded screw, so it can drive the moving plate to move, and the scraper plate can be moved in the mixing drum through the magnetic adsorption of the scraper ring plate by the magnet block, so the raw materials adhering to the inner wall of the mixing drum can be scraped off, so as to avoid the raw materials adhering to the inner wall of the mixing drum and affecting the mixing effect of the raw materials.

However, although the above-mentioned butyl cement production raw material mixing and stirring mechanism can drive the stirring rod to rotate through the stirring motor to drive the driving wheel to drive the threaded screw to rotate, so that the movable plate drives the magnet block to move, and the magnet block drives the scraper plate to scrape the raw materials on the inner wall of the mixing barrel to avoid the raw materials adhering to the inner wall of the mixing barrel and affecting the mixing effect of the raw materials, but, when the magnet block drives the scraper plate to scrape the raw materials on the inner wall of the mixing barrel, the scraper plate must be made of a material that can be adsorbed by the magnet block, which causes the scraper plate to have a large friction with the inner wall of the mixing barrel, thereby causing damage to the scraper plate and the mixing barrel. Therefore, the utility model provides a butyl cement production raw material mixing and stirring mechanism to meet the demand.
