Problems solved by technology

[0003] During the transportation of polyester chips, they will rub against each other to produce powder, and these powders are also transported to pre-crystallization and drying after being fed. However, in the process of pre-crystallization and drying, these powders will form The high melting point material with high crystallinity will make the uniformity of polyester melt worse. When there is a large amount of powder in the slice, the spinning spinneret will stick to the plate seriously, resulting in deterioration of spinning forming, and even producing filaments or blocky spots. , the spin pack life is shortened

Abstract

The invention relates to a feeding system for polyester slices, and relates to the technical field of fiber manufacturing equipment. The feeding system comprises a rack, wherein a discharge hopper, acharge box and a drying box are arranged on the rack; a charge hole is formed in the charge box; a feeding mechanism is arranged on the rack; the feeding mechanism comprises a connecting frame arranged on the rack, a conveying wheel arranged on the connecting frame, a conveyor belt which sleeves the conveying wheel, a plurality of containing hoppers which are arranged on the conveyor belt, a feeding motor arranged on the connecting frame, a cam arranged on the connecting frame, and a shaking motor arranged on the connecting frame; a chip outlet is formed in each containing hipper; and a chip guide plate is arranged on the surface of the conveyor belt among the containing hoppers. According to the feeding system disclosed by the invention, powder in the containing hoppers leaks and drops from the chip outlets through flap of the cam, and powder in slices is removed, so that powder entering the charge box is reduced, and therefore, generation amount of high-melting-point substances in follow-up drying is greatly reduced, uniformity of polyester melt and spinning quality are improved, and the service life of a spinning assembly is prolonged.

Description

technical field [0001] The invention relates to the technical field of fiber manufacturing equipment, in particular to a feeding system for polyester chips. Background technique [0002] The process of producing polyester fiber generally includes feeding, pre-crystallization, drying, melt extrusion, metering, and post-spinning treatment. The purpose of pre-crystallization is to crystallize polyester chips, increase its crystallinity, increase its melting temperature, and prevent subsequent During the heat drying process, polyester agglomerates appeared. [0003] During the transportation of polyester chips, they will rub against each other to produce powder. After being fed, these powders are also transported to pre-crystallization and drying together. However, during the process of pre-crystallization and drying, these powders will form The high melting point material with high crystallinity will make the uniformity of the polyester melt worse. When there is a lot of powde...
