TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic crushing, in particular to an engineering plastic dust-free crushing device. BACKGROUND

[0002] Engineering plastics refers to the plastics used as industrial parts or shell materials, which have high strength, impact resistance, heat resistance, hardness and aging resistance, and can withstand mechanical stress in a wide temperature range and be used in harsh chemical and physical environments for a long time.

[0003] The crushing of engineering plastics is an important link in the process of plastic recycling and reuse, which involves reducing the size of waste or scrap engineering plastics through mechanical force, facilitating subsequent processing or treatment. Through crushing, the volume of engineering plastics is significantly reduced, facilitating storage and transportation.

[0004] In some existing crushing equipment, the contact area between the crushing roller and the plastic is small when crushing spherical engineering plastics, which can cause the spherical plastic to slip on the crushing roller, resulting in a slow crushing process. After crushing is completed, the crushed plastic particles are light and have large friction with the entire conveying plate, causing some particles to fail to fall smoothly into the collection bin, resulting in the accumulation of these particles on the conveying plate below the crushing roller, affecting the overall crushing rate.
