Plastic drying device

Abstract

The invention discloses a plastic drying device. The plastic drying device comprises a box, an upper grinding disc arranged in the box, a lower grinding disc matched with the upper grinding disc, a drying disc arranged between the upper grinding disc and the lower grinding disc, a driving part used for driving the upper grinding disc to rotate, a displacement driving part used for driving the upper grinding disc to move up and down, a rotary shaft fixedly arranged on the upper grinding disc, an anti-rotation and anti-disengagement structure used for achieving anti-rotation fit between the drying disc and the upper grinding disc, and an air delivery component used for delivering hot air into the box. A storage chamber is formed in the upper portion of the box. A feeding port is formed in the upper portion of the storage chamber, and a discharging port is formed in the lower portion of the storage chamber. When the upper grinding disc moves up and down, anti-rotation fit between the upper grinding disc and the drying disc can be released. According to the plastic drying device, it is ensured that materials in the storage chamber can completely enter the drying disc through a discharging structure when discharged, so that material waste rate is low, and the material utilization rate is high.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to a plastic drying device. Background technique [0002] Before injection molding, the plastic raw materials need to be dried and plasticized, so that the plastic becomes molten, and then injected into the injection mold to form a plastic part. However, the traditional drying and plasticizing operations are carried out by separate drying equipment and plasticizing equipment, which not only occupies a large area, but also requires high equipment investment costs and serious energy consumption. [0003] Secondly, the traditional feeding method is to convey the material to the drying plate through the inclined material opening, but under this structure, it is difficult for the material to form a larger parabola when there is less material, and a small part of the material will not be able to enter the drying plate. In a dry dish. Contents of the invention ...
