Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Technical scheme in the application is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the application's protection.
A kind of apparatus for melt spinning for the preparation of artificial grass filaments of the present invention comprises the screw extruder, water-bath cooling device, stretching device, shaping equipment and the coiler device that set gradually, shown in ginseng Fig. 1, in a detailed description of the invention of the present invention, apparatus for melt spinning comprises screw extruder 10, tank 20, first godet roller 30, drawing oven 40, draw roll 50, shaping baking oven 60, setting roll 70, second godet roller 80 and up-coiler 90.
The preparation process of artificial grass filaments is specific as follows:
1. a certain proportion of LLDPE, cooling function masterbatch and Masterbatch are mixed in high-speed mixer;
2. added in single screw extrusion machine by said mixture material and melt extrude, extrusion temperature controls at about 200 DEG C;
3. sample obtains careless silk precursor through water-bath cooling after extruding, and carries out HEAT SETTING process through godet roller, drawing oven, draw roll, shaping baking oven and setting roll.Wherein, draft temperature is 60 DEG C ~ 65 DEG C, and stretch ratio is 4, and heat setting temperature is about 70 DEG C;
4. after a grass precursor HEAT SETTING, then through oiling, reeling, obtain artificial turf fiber product.
Screw extruder comprises screw rod, machine barrel, hopper, head and mould, and masterbatch plastifies uniformly melt by screw extruder, and in this course under institute's build-up pressure, by screw rod continuous print extruder head.
Screw rod is the main parts of extruding machine, and it is directly connected to range of application and the productivity ratio of extruding machine, is made up of the steel alloy of high-strength corrosion-resisting.
Machine barrel is a metallic cylinder, generally with heat-resisting, compressive resistance is higher, the composite steel tube of firm wear-resisting, corrosion resistant steel alloy or interliner alloy steel is made.
Machine barrel coordinates with screw rod, realize the pulverizing of masterbatch, softening, melting, plasticizing, exhaust and compacting, and to formation system continuous uniform conveying sizing material, the length of general machine barrel is 15 ~ 30 times of its diameter, obtain fully heating with abundant plasticizing for principle to make plastics.
In the present invention, screw extruder is have the single screw extrusion machine of a screw rod or have the double screw extruder of two screw rods, and with twin (double) screw extruder, the invention will be further described below.
Shown in ginseng Fig. 2, in the present invention, the first screw rod 11, second screw rod 12 is cylinder, and the first screw rod 11 is provided with the first external screw thread 111, second screw rod 12 and is provided with the second external screw thread 121, and this first external screw thread is identical with the second external screw thread hand of spiral.Machine barrel 13 is cylindrical shape, the inwall of machine barrel 13 has the first internal thread 131 different with the second externally threaded hand of spiral with the second internal thread 132, first internal thread.Further, the first internal thread on the external screw thread on screw rod and the inwall of machine barrel, the hand of spiral of the second internal thread are all different.Melt in machine barrel owing to being subject to the effect of internal thread on external screw thread and machine tube inner wall on screw rod, can fully mixing in machine barrel inside, make each composition in masterbatch can be even.
