A kind of melt spinning device and method for preparing artificial grass silk

Abstract

The invention discloses a melt spinning device and method for preparing artificial turf, comprising an extruding mechanism, a filtering mechanism and a cooling mechanism, the outlet of the extruding mechanism communicates with the top of the filtering mechanism, and the cooling mechanism is located at the bottom of the filtering mechanism The four corners at the bottom of the extrusion mechanism are fixedly connected with the first support legs, and the four corners at the bottom of the cooling mechanism are fixedly connected with the second support legs. The extrusion mechanism includes a motor, a bearing, a feed port, The transmission rod and the extrusion cylinder, the motor is fixedly installed at one end of the extrusion cylinder, the transmission rod is rotated in the inner cavity of the extrusion cylinder, one end of the transmission rod passes through the inner wall of the extrusion cylinder and is fixedly connected with the output shaft of the motor, and the The feed port is set on the top of the extrusion barrel, the filter mechanism includes a discharge barrel, a filter screen, a spinneret, a spinneret and a spinneret hole, and the top of the discharge barrel communicates with the extrusion barrel. The invention has simple operation, is convenient for replacing a new filter screen, saves a lot of time, and improves the production efficiency of silk thread.

Description

technical field [0001] The invention relates to a spinning device, in particular to a melt spinning device and method for preparing artificial turf. Background technique [0002] Melt spinning, also known as melt spinning, is a molding method that takes polymer melt as raw material (like plastic extrusion) and uses a melt spinning machine (like plastic extruder). Any polymer that can be melted or transformed into a viscous fluid state without significant degradation can be spun by melt spinning. During melt spinning, the bulk polymer is melted in the screw extruder and sent to the spinning position, quantitatively sent to the spinning assembly through the spinning pump, filtered, and extruded from the capillary holes of the spinneret. The liquid filaments are gradually solidified when they pass through the cooling medium, and then stretched into filaments at high speed by the winding device below. The filaments are primary fibers, and the primary fibers are post-processed i...

Problems solved by technology

[0003] At present, when artificial turf is prepared, the filtration efficiency of the filter screen may decrease after the existing melt spinning device is used for a long time, causing blockage, and the existing melt spinning device is not convenient for filtering the filter screen. Replacement wastes a lot of time and affects the production efficiency of the silk thread
