Abstract

The invention discloses melt spinning equipment used for preparing artificial grasses. The melt spinning equipment comprises a screw extruder, a water bath cooling device, a stretching device, a sizing device and a winding device; the screw extruder comprises a screw, a cylinder, a hopper, a nose and a mold; the screw is a cylinder object, external screw threads are formed on the screw, the cylinder is cylinder-shaped, internal screw threads are formed on the inner wall of the cylinder, and the external screw threads on the screw and the internal screw threads on the inner wall of the cylinder are different in spiral direction. According to the invention, the internal screw threads are formed on the inner wall of the cylinder, the internal screw threads are matched with the external screw threads on the screw so as to enable extruded melt compositions to be fully and evenly mixed, and the quality of the artificial grasses is improved.

Description

technical field [0001] The invention relates to the technical field of artificial turf preparation equipment, in particular to a melt spinning equipment for preparing artificial turf. Background technique [0002] Artificial turf is a chemical product with natural grass sports performance that imitates grass leaf-like synthetic fibers, implanted on a woven base cloth, and coated with a fixed coating on the back. It is widely used in sports and leisure places. [0003] Artificial turf consists of 3 layers of material. The base layer is composed of rammed soil layer, gravel layer and asphalt or concrete layer. The base layer is required to be solid, non-deformable, smooth and impermeable, that is, the general concrete site. Due to the large area of ​​the hockey field, the base layer must be properly treated during construction to prevent subsidence. If the concrete layer is laid, expansion joints should be cut after the concrete is cured to prevent thermal expansion deformat...
