Jet type spinning machine

Abstract

The invention discloses a jet type spinning machine. The jet type spinning machine comprises a spinner, a filament leading-out device and a base, wherein the spinner is arranged on the base, and comprises a jet-in structure and at least one jet device connected with the jet structure; each jet device comprises a jet pipe body; each jet pipe body comprises a fluid inlet end and a fluid outlet end which are oppositely arranged; each jet pipe body comprises a negative pressure section, a throat section and a section diverging section which are sequentially connected; each negative pressure section is arranged by being close to the corresponding fluid inlet end; a section reducing pipe is arranged on each negative pressure section; each jet pipe body is provided with a filament inlet pipeline on the side wall of the corresponding negative pressure section; the filament leading-out device comprises a container for storing a filament spindle; the high-pressure fluid enters from the jet structure, then enters the jet devices through the corresponding fluid inlet ends, and sequentially passes through the negative pressure sections, the throat sections and the section diverging sections; filaments are drafted from the container of the filament leading-out device to an inlet of the filament inlet pipeline; under the action of the negative pressure, the filaments are sucked into, and then are jetted together with the high-pressure fluid from the spinning end, so that breaking and blocking of the filaments are avoided.

Description

technical field [0001] The invention relates to a spinneret, in particular to a jet-type spinneret. Background technique [0002] In recent years, during the construction process, a large number of mountains have been excavated, quarried, and many exposed rock surfaces have been formed, which not only destroys vegetation, easily causes water and soil erosion, but also damages the ecological landscape. The traditional greening method for rocky slopes is hanging nets and soil spray broadcast. However, the vegetation layer constructed by this process on high and steep rocky slopes is not resistant to rain erosion. Once a heavy rain occurs, the vegetation layer is often eroded and collapsed, leaving only barbed wire, resulting in failure of slope protection. There is a kind of fiber silk reinforcing soil planting method, which is a further improvement method of the traditional hanging net guest soil spraying technology. The soil substrate is continuously sprayed by the wet spr...

There is a kind of fiber silk reinforcing soil planting method, which is a further improvement method of the traditional hanging net guest soil spraying technology. The soil substrate is continuously sprayed by the wet spraying machine, and the spinning machine sprays fiber filaments, but because the fiber filaments are thin and light, they are easily broken with the fluctuation of pressure and the flow of air, and these broken filaments are easily blocked in the spray nozzle. In the filament tube, it is difficult for the current spinneret to eject fiber filaments, it is easy to block, and it is difficult to keep the filament filaments continuously. There are also obvious restrictions on the material of the filament filaments. Generally, only polyester filaments can be sprayed, and the high-pressure fluid is limited to high-pressure air. Due to the limitation of the spinneret, the continuous spinneret planting method has not been effectively promoted and applied
