A stretching false twisting device for polyester filament and its processing technology

Abstract

The invention discloses a stretching false twisting device for polyester filaments, which comprises: a casing, a balance mechanism, a heating device, a stretching mechanism, a false twisting mechanism and a winding forming mechanism are arranged in the casing, and the heating device The first heating mechanism and the second heating mechanism are arranged in the middle, the balance mechanism is arranged at the rear of the wire drawing frame, the first heating mechanism is arranged at the rear of the balance mechanism, the stretching mechanism is arranged at the rear of the first heating mechanism, and the false twisting mechanism is arranged at the rear of the balance mechanism. Behind the stretching mechanism, the second heating mechanism is arranged behind the false twisting mechanism, the winding forming mechanism is arranged behind the second heating mechanism, and the top of the housing is provided with a dust suction mechanism. The present invention presses the thread through the balance mechanism, avoids uneven problems such as curling, and effectively prevents it from being affected by the side wind. The structure of the whole device is simple, easy to operate, and effectively reduces broken threads. The dust mechanism can effectively improve its processing environment and avoid its impact on production.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a stretching false twisting device for polyester filaments and a processing technology thereof. Background technique [0002] With the rapid development of social economy, all walks of life are making continuous progress. The same is true in the textile industry. Drawing false twisting is a necessary process in the spinning process of polyester filament. When the silk thread is taken off and off the wire frame, it will often be entangled, which will seriously affect its production efficiency, and will also cause damage to the wound thread. The structure and material of the thread will also cause damage to the thread, and will also produce a large number of threads, which will affect the processing environment and is not conducive to the processing of the filament; [0003] At the same time, it is often necessary to heat the filament during processing. The existing heating mech...

Problems solved by technology

When the silk thread is taken off and off the wire frame, it will often be entangled, which will seriously affect its production efficiency, and will also cause damage to the wound thread. The structure and material of the thread will also cause damage to the thread, and will also produce a large number of threads, which will affect the processing environment and is not conducive to the processing of the filament;

[0003] At the same time, it is often necessary to heat the filament during processing. The existing heating mechanism often has the problem of uneven heating, which seriously affects the heating of the filament and the quality of its processing. Therefore, the existing drawing Stretching and false twisting device has yet to be
