Polymer material smashing and screening device

Abstract

The invention discloses a polymer material smashing and screening device comprising a fixing frame, a shell, a material falling hopper, electric push rods, a cross plate, a first motor, a screening shell, a first cavity, a second cavity, a third cavity, a top cover, first through holes, second through holes, a second motor, a cutting shaft, blades, a first bearing, inclined plates, two grinding wheels, a rotating shaft, a partition plate, a fixed block, a third motor, a base plate and a second bearing. The polymer material smashing and screening device is reasonable in structure, materials canbe cut up primarily through the blades on the cutting shaft, the materials are grinded through the two grinding wheels, after being grinded, the materials are grounded again through the grinding wheels and the fixed block, and after the materials are processed for three times, the material smashing effect can be improved; the smashed materials can directly enter the first cavity through the material falling hopper, screening of the materials can be conducted, conveyance conducted by means of a power device is not needed, the materials can be screened through the first through holes and the second through holes, and materials of different sizes can be accumulated in the first cavity, the second cavity and the third cavity correspondingly.

Description

technical field [0001] The invention relates to a material crushing and screening device, in particular to a polymer material crushing and screening device, which belongs to the technical field of polymer processing equipment application. Background technique [0002] Macromolecular compounds are referred to as macromolecules, also known as macromolecules, and generally refer to compounds with a relative molecular mass of several thousand to several million. The vast majority of macromolecular compounds are mixtures of many homologues with different relative molecular masses. The relative molecular mass is the average relative molecular weight. [0003] A variety of different substances are mixed in the polymer material, and the polymer material needs to be crushed and sieved. The crushing effect of the general crushing device may not be good; after the material is crushed, it may not be directly sieved in the screening device, and it may be necessary to rely on the outside ...

Problems solved by technology

[0003] A variety of different substances are mixed in the polymer material, and the polymer material needs to be crushed and sieved. The crushing effect of the general crushing device may not be good; the material may not be sieved directly in the sieving device after crushing, and it may be necessary to rely on the outside world. Power, the operation may be more complicated
