The side blowing device 5 includes an air conditioner having a cooling function.
The mechanical drafting device 6 comprises a first mechanical rotating roller 61 and a second mechanical rotating roller 62.
The charging machine 1, the screw extruder 2 and the melt filter 3 are raw material processing mechanisms which are sequentially connected through pipelines.
The wire feeder 7 is a fiber conveying and arranging mechanism.
The silk swinging machine 8, the net forming machine 9 and the reciprocating net laying machine 10 which are connected in sequence are silk three-step net forming mechanisms.
The reciprocating lapping machine 10 is a secondary lapping mechanism.
The operation of this embodiment is as follows:
1, charging
The polypropylene slices are automatically added into the hopper by the feeder 1 according to the speed of the screw extruder 2.
2, screw extruder
The added slices are melted into melt under the double action of converting mechanical energy formed by electric heating and screw extrusion into thermal energy, and the melt is extruded from the top of the screw extruder.
3, melt filtration
The melt passes through a melt filter 3 under a certain pressure to filter out impurities.
4, spinning
The filtered melt enters a spinning box 4, and the melt is quantitatively sprayed out of the small holes of the spinneret plate of the component by a metering pump.
5, cooling by cross air blow
The melt stream emerging from the spinneret is supplied to a cooling device by a cross-blow. The air source of the cross air blow is provided by an air conditioner.
6, mechanical drawing
The nascent fiber from the spinneret is not only coarse, but also has low strength due to the disordered arrangement of the microscopic molecular structure. At the moment, the mechanical roller is used for drafting the fiber, so that the fiber has the quality of high strength and low elongation, and the fiber also becomes thin and soft; the linear speed of the first mechanical rotating roller 61 is faster than the speed of the spinning box 4, and the linear speed of the second mechanical rotating roller 62 is faster than the speed of the first mechanical rotating roller 61, and the first mechanical rotating roller is twice mechanical drafting.
7, fiber transport
The high-strength fibers are sent to a silk swinging machine 8 by a wire feeder 7 under the drive of compressed air.
8, swinging silk
The fibers are transversely swung to fall on the web former 9 along with the high-frequency swing of the swinging piece on the silk swinging machine 8.
9, forming a net
The fibres are swung transversely onto the wire of the web former 9, and in the course of movement of the wire, the fibres form a narrow, thin fibre layer which is fed to the reciprocating lapper 10.
10, reciprocating lapping machine
The reciprocating lapper 10 moves the narrow fiber layers back and forth to lay the narrow fiber layers into a wide fiber web, and sends the wide fiber web to the needle loom.
11, preliminary needling
The stacked fiber net is fluffy, the fluffy fiber net is flattened by a feeding roller of the pre-needling machine 11, and the first needling is carried out to obtain the preliminary cloth.
12, main needling
After the preliminary cloth formation, the main needling machine 12 continues needling, opposite to the direction of the preliminary needling, the fibers are further entangled, and the processing is basically finished.
13, winding up
The geotextile with the rough edge is cut edge on a winding machine 13, rolled into a cylindrical finished product according to a set length, packaged and put in storage.
