Drying device for plastic particles

Abstract

The invention discloses a drying device for plastic particles. The drying device for the plastic particles comprises a box body; a material collecting groove is formed in the box body; discharging holes are formed in the bottom of the material collecting groove; first ventilation holes are formed in the side wall of the material collecting groove; a connection rod is fixedly arranged on the innersurface of the top of the box body; the edge of the material collecting groove is arranged on the connection rod in a sleeved manner; the lower end of the connection rod is provided with a stopping block; a compression spring is arranged between the stopping block and the material collecting groove; the compression spring is arranged on the connection rod in a sleeved manner, and one end of the compression spring is connected with the material collecting groove; the other end of the compression spring is connected with the stopping block; a vibration motor is arranged on the outer surface of the material collecting groove; a stirring mechanism is arranged in the material collecting groove; an unloading plate is arranged below the material collecting groove; the unloading plate is providedwith second ventilation holes; the bottom of the box body is provided with an air inlet; the air inlet is internally provided with an air blower and a heating resistance wire; and a switching mechanism capable of opening and closing the discharging holes is arranged below the material collecting groove. According to the drying device for the plastic particles, when hot air is blown out of the airblower, the stirring mechanism performs stirring on the plastic particles, uniform drying of the plastic particles is promoted, and automatic unloading can be achieved.

Description

technical field [0001] The invention relates to the field of plastic production and processing equipment, in particular to a plastic particle drying device. Background technique [0002] During the production of plastics, extruders are used to extrude plastic strips at high temperatures. After cooling and forming, the plastic strips are dried and sent to the pelletizer. Finally, the pelletizer cuts the plastic strips into granules. The commonly used cooling method for plastic strips is water cooling. Most of the moisture on the plastic strips can be removed by using a drying device before pelletizing, but not all of the moisture can be removed. The granulated plastic particles still contain moisture, so the moisture needs to be removed to meet the needs of subsequent processing. Contents of the invention [0003] In view of the above technical problems, the object of the present invention is to propose a drying device for plastic granules, which can evenly dry the plastic...
