Abstract

The invention provides a screw discharging device. The screw discharging device comprises a sleeve and a screw rotationally mounted in the sleeve. A plurality of circles of outer tooth sets are axially fixed to the side wall of the discharging end of the screw. Each circle of outer tooth set is composed of a plurality of outer teeth arranged in the circumferential direction of the screw at intervals. A plurality of circles of inner tooth sets are axially fixed to the inner wall of the sleeve. Each circle of inner tooth set is composed of a plurality of inner teeth arranged in the circumferential direction of the sleeve at intervals. The outer tooth sets and the inner tooth sets are staggered axially. The inner teeth and the screw are arranged at intervals. The outer teeth and the sleeve are arranged at intervals.

Description

technical field [0001] The invention relates to the production of melt-spun dyed yarn and other melt-spun yarns with added powder, in particular to a screw discharge device. Background technique [0002] The screw extruder is a material melting, extruding and blending equipment. The raw materials are fed into the extruder through the feeding device and then fully mixed and extruded under the action of the screw, heated and formed into a melt. [0003] The screw discharge device is an important part of the screw extruder. The screw discharge device generally consists of a screw and a sleeve. The screw rotates relative to the sleeve. At present, the ordinary screw generally consists of a rod body and a screw thread fixed on the rod body, or For example, the screw of a single-screw extruder disclosed in Chinese Patent Publication No. 203141815U includes a feed section, a compression separation section, and a metering section from front to back. The feed section is provided with...
