Polyester pre-oriented yarn production equipment

Abstract

The invention discloses polyester pre-oriented yarn production equipment, and relates to the technical field of polyester pre-oriented yarn production. The technical problem is solved that the production efficiency of polyester pre-oriented yarn is low. According to the technical scheme, the polyester pre-oriented yarn production equipment includes screw extrusion spinning machines, circulating air blowing devices, a channel and a winding device which are arranged in sequence; each screw extrusion spinning machine includes a screw extrusion machine and a spinning box which is arranged at the discharging end of the screw extrusion machine and further includes a metal cooling part which is arranged between the discharging opening of the spinning box and the feeding opening of the corresponding circulating air blowing device; a cooling part formed by a plurality of tow paths is arranged on each metal cooling part, and anti-sticking coatings coat the inner walls of the tow paths. The polyester pre-oriented yarn production equipment has the advantage of improving the polyester pre-oriented yarn production efficiency.

Description

technical field [0001] The invention relates to the technical field of POY yarn production, more specifically, it relates to a POY yarn production equipment. Background technique [0002] Existing POY yarn production equipment usually consists of main parts such as screw extrusion spinning machine, ring blowing device, tunnel and winding machine, which melts, measures and spins the raw material through screw extrusion spinning machine, and then Use the side blowing device to carry out side blowing cooling and forming, and finally use the winding machine to wind the cooled and formed POY yarn. [0003] Wherein, in the prior art, when the POY wire is cooled by the ring blowing device, it will swing because of the air flow blown out by the ring blowing device. In order to prevent the multiple POY wires extruded by the screw extrusion spinning machine from sticking together, The output of the screw extrusion spinning machine must be controlled between 4-5 bundles to ensure the ...

Problems solved by technology

[0003] Wherein, in the prior art, when the POY wire is cooled by the ring blowing device, it will swing because of the air flow blown out by the ring blowing device. In order to prevent the multiple POY wires extruded by the screw extrusion spinning machine from sticking together, The output of the screw extrusion spinning machine must be controlled between 4-5 bundles to ensure the spacing between the POY filaments, resulting in a certain limitation in the production efficiency of POY filaments, so it needs to be improved
