Efficient melt spinning machine

Abstract

The invention discloses a high-efficiency melt spinning machine, which comprises a screw casing, a polymer hopper is installed on the top of the screw casing, a screw is arranged inside the screw casing, and a motor is connected to one end of the screw through a rotating shaft. The outside of the screw is provided with a heater, the inside of the screw housing is provided with a thermal insulation jacket near the side of the screw, the bottom of the screw housing is equipped with a spinning box, and the inside of the spinning box is provided with a metering pump, and a filter is arranged above the metering pump, a spinneret is arranged at the bottom of the metering pump, a spinneret is arranged inside the spinneret, and a Several spinneret holes, the present invention is equipped with a heat transfer plate, the heat transfer plate is made of heat-conducting material, the heat transfer plate is set at the bottom of the spinneret plate to keep the high temperature continuously, avoiding the accumulation and solidification of raw materials, thereby improving the spraying efficiency. Sustained production capacity of silk board.

Description

technical field [0001] The invention belongs to the technical field of spinning machines, and in particular relates to a high-efficiency melt spinning machine. Background technique [0002] A spinning machine is a machine that makes a fiber-forming polymer solution or melt into filaments. According to different fiber spinning methods, spinning machines are divided into wet spinning machines, melt spinning machines, and dry spinning machines. There are three types of spinning machines, used for spinning equipment such as polyester, nylon and polypropylene. The characteristic is that the thin stream of melt solidifies into fibers when it encounters cold wind. Yes, one of the main forming methods of chemical fibers, referred to as melt spinning, the main varieties of synthetic fibers such as polyester, nylon and polypropylene are produced by melt spinning. The main characteristics of melt spinning are high winding speed, no need for solvents and precipitants, equipment Simple,...
