s100, manufacturing the straight wires required by the preparation of the twisted grass wires through the straight wire preparation device 2.

The steps of manufacturing the straight wire by the straight wire manufacturing device 2 mainly comprise: mixing, melt extruding and drawing

Stretching, sizing and removing water.

Step one, mixing materials: the raw materials for manufacturing the straight filaments are poured into a mixing barrel to be mixed to form mixed raw materials, and the main component of the raw materials for manufacturing the straight filaments is PE (polyethylene) polyethylene or PP (polypropylene).

And a second step of melt-extruding, heating and mixing the raw materials to melt them, and then extruding the molten raw materials to form a threadlike raw yarn.

And thirdly, stretching the extruded thick filaments into water, rapidly cooling the thick filaments in a molten state, gradually losing viscosity on the surface of the thick filaments, greatly improving the overall toughness of the thick filaments, sequentially winding the thick filaments on rotating rollers at two different linear speeds, and rotating the two rotating rollers.

Fourthly, shaping, namely, before the thick silk is stretched, because the thick silk begins to stretch into water, shaping operation is started at the moment, and because water can carry out primary cooling on the thick silk entering the water, the surface of the thick silk loses viscosity, and the thick silk still has considerable softness; in addition, in the process of stretching the thick filaments, as the thick filaments are rapidly stretched, the surface area of the thick filaments in contact with water in the process of stretching is rapidly enlarged, and the thick filaments are further cooled by water, so that the stretched thick filaments can be further shaped; in addition, after the thick filaments are stretched into thin and straight filaments, the thick filaments can stay in water for a period of time, and the stretched thin and straight filaments are further cooled and shaped by using water.

And fifthly, removing water, namely pulling out water from the thin straight filaments after the temperature reduction in the water, blowing off the water on the surfaces of the thin straight filaments by using a fan, and then air-drying the thin straight filaments.

It should be noted that the step of manufacturing the straight wire by sequentially performing the above five steps by the straight wire manufacturing apparatus 2 belongs to the prior art, and the five steps are expanded here to facilitate the explanation of the step of manufacturing the straight wire.

S200, preparing the curved silk required by the twisted grass silk through the curved silk preparation device 1,

and the curved wire is wound by the curved wire winding drum 35.

The steps of the curved yarn preparation device 1 for preparing the curved yarn mainly comprise: mixing, melt extruding, stretching,

Water removal, air deformation and cooling and shaping.

It should be noted that, in the manufacturing process of the curved yarn, the four steps of mixing, melt extrusion, stretching and water removal are consistent with the corresponding steps of the manufacturing process of the straight yarn in S100, and the curved yarn is still in the state of the straight yarn after the step of water removal is completed.

Further, carry out the air deformation, pull up the straight silk through the dewatering, then use hot-air to blow to the straight silk, straight silk self can soften rapidly under hot-air's effect, and owing to receive wind-force, the straight silk that has softened can rapid bending deformation, forms the higher and softer curved silk of self structure of temperature.

And further, cooling and shaping are carried out, cold air is rapidly used for cooling the bent wire which is higher in temperature and softer in self structure, the bent wire can be rapidly cooled and the structural strength of the bent wire can be rapidly improved, and therefore the bent wire which is relatively stable in form is formed.

It should be noted that the steps of manufacturing the curved yarn by sequentially executing the above steps by the curved yarn manufacturing device 2 belong to the prior art, and the steps of manufacturing the curved yarn are expanded here, so that the description of the straight yarn manufacturing process is facilitated.

Furthermore, the formed curved wire with stable shape is wound on the curved wire winding drum 35 through the curved wire winding device 3, and after the winding is finished, the curved wire winding drum 35 which finishes the winding is detached from the curved wire winding device 3 and is rotationally connected to the winding drum placing device 4. It should be noted that, after the curved yarn winding drum is moved to the winding drum placing device 4, if the curved yarn on the curved yarn winding drum is pulled, the curved yarn winding drum 35 can rotate on the winding drum placing device 4 due to the pulling of the curved yarn.

S300, twisting the straight filaments directly manufactured by the straight filament manufacturing device 2 and the curved filaments wound on the curved filament winding barrel 35 in a plying manner to generate the plied grass filaments.

The straight wire produced in the step S100 is directly wound in the stranding roller groove 75 on the stranding roller 74, and then the curved wire on the curved wire winding drum 35 connected with the winding drum placing device 4 in a rotating mode is also wound in the stranding roller groove 75 on the same stranding roller 74, so that the straight wire and the curved wire can be attached together, and the straight wire and the curved wire can be stranded to form the combined stranded wire.

Before the curved wires on the curved wire winding drum are plied to the plying device 7, whether the curved wires to be plied to the plying device are broken needs to be detected by the broken wire detection alarm device 5; if the broken curved yarn is detected, an alarm signal is immediately sent out through an alarm signal lamp 57 on the broken yarn detection alarm device 5 to prompt the broken curved yarn, so that the adverse effect of the broken curved yarn on the subsequent production of the twisted straw yarn is avoided, and the loss of the broken curved yarn is reduced; if the broken yarn is not detected by the broken yarn detection alarm device 5, the curved yarn is continuously conveyed to the stranding device 7.

It should be noted that if the broken wire is not detected by the broken wire detection alarm device 5, the tension of the broken wire is required to be adjusted by the tension adjustment device 6, the tension of the broken wire connected to the bottom of the rotating wheel 64 is sensed by the pressure sensor 63, and if the tension of the broken wire is found not to be within the preset tension threshold range, the PLC in the tension adjustment device 6 controls the lifting of the piston rod of the second cylinder, so that the tension of the broken wire is within the tension threshold range. The tension of the bent wire which is not broken is adjusted, so that the bent wire can be prevented from being broken due to overlarge tension, the tension of the bent wire is adjusted, and the bent wire can be wound conveniently, so that the wound bent wire is not too loose or too tight.

Further, twist to the involution silk through twisting device 8, will close the silk and pass the silk ring 88 that closes on rotatory ring 84, thereby drive rotatory ring 84 through third motor 86 and rotate and make and close silk ring 88 and then rotate, the rotation of silk ring 88 can make straight silk and curved silk twine each other together, so be convenient for form the used plying grass silk on the artifical lawn.

Still further, through straw silk collection device 9 to the formation strand straw silk roll, it is specific. The twisted strands of grass are wound up using a collection roller 94 driven by a fourth motor 93.

Finally, because collection roller 94 is not convenient for take off from grass silk collection device 9, for the convenience of transportation and selling the plying grass silk, can take off the plying grass silk of rolling on the collection roller 94 and twine again on the finished product reel to be convenient for the transportation and the selling of the plying grass silk.
