Screening device for engineering plastic processing equipment

Abstract

The invention discloses a screening device for engineering plastic processing equipment. The screening device comprises a screening box. The interior of the screening box is equipped with a receivingbox. The upper ends two sides of the receiving box are connected with the inner wall of the screening box by springs, and the bottom of the receiving box is provided with a coarse screen. A qualifiedvibrating screen is arranged below the receiving box, a fine vibrating screen is arranged below the qualified vibrating screen, a stirring motor is arranged between feeding ports, and the output end of the stirring motor is fixedly connected with a stirring shaft. The stirring shaft passes through the top of the screening box and extends into the receiving box. One outer side of the screening boxis provided with a hydraulic cylinder, and the interior of the hydraulic cylinder is provided with a piston rod, and one end of the piston rod extends into the screening box and is fixedly connected to the receiving box. A hot air blower is connected to the back of the screening box, and the hot air blower is connected with a hot air hood through an air duct. The screening device disclosed by theinvention can be used for scattering and drying treatment when engineering plastic is screened, thus the engineering plastics are ensured to be thoroughly screened, the screening effect is good, and the screening efficiency is high.

Description

technical field [0001] The invention relates to the technical field of engineering plastic processing equipment, in particular to a screening device for engineering plastic processing equipment. Background technique [0002] Engineering plastics can be used as engineering materials and plastics that replace metal manufacturing machine parts, etc. Engineering plastics have excellent comprehensive properties, high rigidity, small creep, high mechanical strength, good heat resistance, and good electrical insulation. Long-term use in chemical and physical environments can replace metals as engineering structural materials, but the price is more expensive and the output is small. During the production and processing of engineering plastics, some unqualified products will appear. The size of the particles is different, so it needs to be screened. The existing screening device is only an ordinary coarse screen, which has poor screening effect and low work efficiency. If the enginee...
