Abstract

The invention discloses a cooling device of a plastic extruder, belonging to the technical field of mechanical manufacturing of plastics. The cooling device comprises a tank body containing cooling water, wherein a water inlet pipe is arranged on the tank body; a blower with an air outlet connected with an air outlet pipe is arranged outside the tank body; the air outlet pipe extends into the tank body and is provided with a plurality of air outlets; a water level sensor and temperature sensors are respectively arranged at the two ends in the tank body. The cooling device has the effect of solving the problem that poor cooling effects are caused by non-uniformity of water temperature in the tank, thus affecting the properties and textures of the plastics.

Description

technical field [0001] The invention relates to the technical field of plastic machinery manufacturing, in particular to a plastic extruder cooling device. Background technique [0002] At present, in the production of modified plastic materials, the production method is to produce granular raw materials on the extrusion granulation unit. The equipment of the extrusion granulation production line mainly consists of an extruder, a cooling water tank, a drying fan, a traction mechanism and a pelletizer. and other components; the cooling water tank is located between the plastic extruder and the pelletizer. When the plastic extruder extrudes the plastic strips, the subsequent process is to implement cooling of the plastic strips. The water temperature of the entire water tank must be maintained Evenly controlled between 25 degrees and 35 degrees to ensure the stability of plastic properties; the water inlet of the cooling water tank currently used in production is set at one en...
