A kind of lawn rayon production line and production method

Abstract

The invention discloses a lawn rayon production line and production method. The lawn rayon production line comprises monofilament production equipment, after finishing equipment and a plying and twisting unit which are installed in sequence; two extruders of the monofilament production equipment of the lawn rayon production line are arranged in parallel and can produce monofilament with different colors and different types; the plying and twisting equipment conducts plying and twisting on the monofilament produced through the production line and monofilament which needs to be twisted, rewinding does not need to be conducted repeatedly, the process time and the workshop space are saved, requirements for plying and twisting production of two or more monofilament are met, and the production efficiency is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of plastic processing, more specifically, to an artificial turf plastic monofilament production line and a lawn rayon production method based on the production line. Background technique

[0002] The existing plastic monofilament production mode as disclosed in Chinese patent CN103465452A is: according to the requirements of parameters such as monofilament color and denier, each monofilament is produced by a production line (single unit production line), and the monofilament is extruded by an extruder. After coming out, after finishing processes such as cooling, traction, drafting, heat setting, etc., it needs to be wound into a yarn bobbin; the monofilament yarn bobbins of different colors are plied and twisted into a tapered shape on the twisting equipment. The yarn bobbin; the yarn bobbin is then rewound into a single cylindrical yarn bobbin. The overall production process is: yarn production and yarn tw...
