underwater cutting system

Abstract

The invention discloses an underwater cutting system. The underwater cutting system comprises a grain cutting system, a waterway system and a dehydrator which are sequentially connected, wherein the grain cutting system comprises a grain cutting motor, a grain cutting cylinder, a push rod and a hot water downward cutting die head; the grain cutting motor comprises a motor shell and a motor shaft; the motor shaft is a hollow shaft with a hollow channel; the push rod is cooperatively mounted in the hollow channel of the motor shaft in a sleeving manner; the two ends of the push rod extend out of the motor shaft; the head end of the push rod extends out of the motor shell, is flush with the head end of the motor shaft, and is connected with the hot water downward cutting die head through a grain cutting knife rest; the tail end of the push rod extends out of the motor shell, and is connected with the grain cutting cylinder through a bearing seat mounted on the motor shell; the grain cutting cylinder comprises a cylinder body and a cylinder rod arranged inside the cylinder body; the head end of the cylinder rod extends out of the cylinder body; the cylinder rod penetrates into the bearing seat to be propped against the tail end of the push rod; the tail end of the push rod is connected with the bearing seat through a first bearing; and a rod body of the push rod is connected with the motor shaft through a second bearing. According to the underwater cutting system, when the motor rotates at a high speed, a cutter is automatically adjusted to be concentric with a template surface, the cutter and the template surface are guaranteed to always tightly fit, and the service life is effectively prolonged.

Description

technical field [0001] The invention relates to a pelletizing device, in particular to an underwater cutting system, which belongs to the technical field of mechanical equipment. Background technique [0002] At present, the processing of plastic products in my country is to a large extent plasticized and processed into plastic powder. The extruder is the most widely used equipment in polymer processing. After the polymer is mixed with various additives, it is fed into the extruder to be melted, and further mixed evenly. After passing through a multi-hole die, multiple strips are formed, and then cut into Pellets can be divided into hot-cut pellets and cold-cut pellets. Among them, hot-cut pellets are cut off with a blade while cooling with air or water after leaving the die.

AI Technical Summary

Problems solved by technology

[0003] Underwater granulator is a kind of eager plastic particle cutting equipment commonly used in the plastic granulation industry, but the current underwater granulator still has the disadvantages of complex and bulky structure, large space occupation, inconvenient use, etc., and the motor is running. The degree of cooperation with the template surface is poor, which directly affects the pelletizing effect and the service life of the cutter and the template surface
