Description

Technical Field

[0001] The invention relates to the technical field of material mixing, in particular to a device for mixing polypropylene processing raw materials. Background Art

[0002] Polypropylene is divided into three types according to the arrangement position of methyl groups: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. It is non-toxic, odorless, has low density, high heat resistance, does not absorb water, and has good electrical insulation. It is widely used in the production of fiber products, medical devices, automobiles, chemical containers and other products. It is also used for the packaging of food and medicine. For example, a special mixing device for polypropylene masterbatch with application number CN202323058758.4 is provided. When the above technical solution is implemented, the material needs to be heated to a molten state during polypropylene processing and then mixed with the material to achieve a more uniform mixing. Even if the heated material is still kept warm during mixing in the tank, there will still be a temperature difference in the stirring parts, causing part of the material to solidify on the stirring parts.

After the particles are heated to a molten state, other materials are added thereto by opening the upper cover of the feeding port, and then the mixing motor seat is started to stir and mix.

[0062] The on-off control cylinder 406 is activated to push the on-off control slide frame 407 at the lower end, thereby driving the internal sliding slide frame rod 409, thereby enabling the rotary plug control turntable 408 to rotate, and synchronously causing the inner rotary plug main shaft 410 to rotate. By changing the position of the rotary plug top seat 411 and the rotary plug spring piece 412, the rotary plug top seat 411 and the rotary plug spring piece 412 can open the gap between them and the inner wall of the discharge main pipe 401, and discharge the material through the discharge funnel 402;

[0063] Among them, the mixing tank cover 6 can be opened by lifting the base sleeve 503 sliding on the base sleeve rod 502, and the first transfer slot 505, the second transfer slot 506 and the limit block 507 limit the mixing tank cover 6 to prevent it from shifting to other places.
