Description

Technical Field

[0001] The utility model belongs to the technical field of vibrating screens and relates to a vibrating screen for sorting recycled plastic particles. Background Art

[0002] The raw materials for extrusion molding of plastic film are generally large granular plastics or some plastic edge materials. Therefore, these plastic particles are usually crushed to avoid unevenness or individual difficulty in melting during the hot melt process. Generally, plastic particles need to be screened before injection molding, and a screening device will be used. However, some crystal particles are of different sizes, so particles of different sizes need to be selected and separated. Existing small factories use rotary screening devices, and the rotary vibrating screen uses an upright motor as the excitation source. Eccentric weights are installed at the upper and lower ends of the motor to convert the motor's rotational motion into horizontal, vertical, and inclined three-dimensional motion, and then transmit this motion to the screen surface, thereby making the internal structure complex. This results in high production and manufacturing costs and maintenance difficulties for small processing factories.
