Abstract
A cooling unit for a modification process of long glass fiber reinforced plastic comprises a plurality of cooling water tanks arranged in parallel. Each cooling water tank is composed of a small tank and a large tank arranged below the small tank; the temperature of water in the large and small tanks decreases gradually along a moving direction of strips; grilles are disposed at two ends of the top of the small tank and are composed of a plurality of circular columns; a gap between every circular columns is used as a passage allowing passage of the strips; circulating pumps are disposed in the large and small tanks and provide water to the small tank through a pipe, the water in the small tank can flow back into the large tank through the grilles, and the water level of the small tank is lower than the horizontal plane which the strips pass by. The cooling unit has the advantages that the multiple cooling tanks of different temperatures are used to gradually cool the strips, defective rate of the strips can be evidently decreased, lean production is achieved, and waste of cooling water is avoided.
Description
Technical field
The present invention relates to modifying plastics tie rod production device, specifically a kind of long glass fiber reinforced plastics modified technique cooling device.
Background technology
In existing long glass fiber reinforced plastics modifying process, after glass is combined with the polymer of melting in impregnating bath, obtain the material strip of cylindrical endless through tie rod technique, material strip, through traction, enters process for cooling; General process for cooling adopts the form of water-cooled, and in Cooling Process, material strip is from the molten condition of high temperature often, directly enter the container that is equipped with low-temperature cooling water, cool material strip, cooled material strip continues mobile under the effect of traction, enters into technique that is air-dry and granulation.But such production procedure Shortcomings, mainly comprises:
