Water tank cooling adjusting device for plastic granulator

Abstract

The invention relates to the technical field of plastic granulators and discloses a water tank cooling adjusting device for a plastic granulator. The water tank cooling adjusting device comprises a machine body; a cylinder is arranged at the upper part of the machine body; a fixed piece is arranged on the surface of the cylinder; a screw rod is arranged in the cylinder; a motor is arranged on theside face of the cylinder; a rotary shaft is arranged on the surface of the motor; a speed variator is arranged on the side face of the rotary shaft; an electric power device is arranged on the side face of the machine body; a wire is arranged on the surface of the electric power device; and an additional wheel is arranged on the surface of the rotary shaft. According to the water tank cooling adjusting device, through cooperative application of a thermistor, the electric power device and the motor and through cooperative application of the motor and the screw rod, the extruding wire yieldingspeed of the screw rod can be adjusted according to the temperature of liquid in a cooling water tank, the cooling effect of a plastic drawing wire in the cooling water tank is ensured, and the particle forming quality of the plastic drawing wire is improved.

Description

technical field [0001] The invention relates to the technical field of plastic granulators, in particular to a water tank cooling adjustment device for plastic granulators. Background technique [0002] The plastic granulator is a kind of plastic extrusion molding equipment. It heats the plastic raw material to make it into a viscous flow state. Under the action of pressure, it is continuously extruded through the extrusion equipment, and then cooled. device to obtain cylindrical or elliptical plastic particles. In the production process of the plastic granulator, the extrusion process and the wire drawing cooling process will be involved. [0003] In the existing equipment, the running speed of the equipment cannot be adjusted when the plastic raw material is extruded and drawn and then cooled. When the temperature of the cooling liquid rises, the cooling time of the drawing will not change, which reduces the cooling effect of the drawing. When granulating, the particles ...
