Description
Technical Field
The invention relates to the technical field of plastic woven fabric product manufacturing, in particular to a PET (polyethylene terephthalate) polyester flat filament extrusion die head.
Background
At present, the demand of plastic woven cloth in domestic and foreign people life is large, at present, the woven cloth is woven into woven cloth by a plastic circular weaving machine after polypropylene PP or polyethylene PE is used as a raw material to produce plastic flat filaments by a plastic flat filament drawing machine set, and the plastic flat filaments are used for grass-proof cloth, sun-shading nets and plastic woven bags, but the anti-aging performance of the woven cloth produced by using the polypropylene PP or polyethylene PE as the raw material is poor, and the woven cloth can only be used for several months in the open air. If the polyester flat filament using polyethylene terephthalate PET as raw material is used to produce weaving cloth, the mechanical property is better than that of PP, and the aging resistance can be better for several years, at present, many technicians in China try to produce high-performance and aging-resistant PET flat filament and weaving cloth by using PET, however, most manufacturers still continue to use the processes of extruding, cooling, slitting, stretching and shaping of PP, and because of the significant difference in molecular structures and properties between PET and PP, the continuous PP production process cannot produce PET flat filaments, in order to overcome the above-mentioned drawbacks, there are proposed solutions, "a flat die head for producing PET flat filaments", patent application No. 201320374856.6, the die is characterized in that a spinneret orifice is formed by meshing an upper die lip and a lower die lip, the die is difficult to produce and process, the extruded melt is disordered and cannot be normally produced due to the fact that the processing precision cannot be achieved, and the defect that the whole die head needs to be replaced when flat filaments of different specifications are produced exists.
Disclosure of Invention
The invention aims to overcome the defects and provides a PET (polyethylene terephthalate) polyester flat filament extrusion die head, which comprises a left die sheet 1 and a right die sheet 3, wherein the two die sheets are fastened together by screws, and a die lip elastomer 7 of each die sheet is provided with an adjusting screw 6, and is characterized in that: a template 9 is arranged between the die lips of the two templates, rectangular through holes 31 with a plurality of door openings are designed on the template 9, and the rectangular through holes 31 are uniformly and linearly arranged on the template 9.
Preferably, the upper part of the die piece 9 mounted between the die lips is provided with a long strip plate 10 in a matching way, the long strip plate 10 is provided with convex ribs 32 with the same number as the rectangular through holes 31 of the die piece, the convex ribs 32 on the long strip plate 10 are mounted in a matching way with the rectangular through holes 31 on the die piece, the long strip plate 10 and the die piece 32 are mounted in a cross way, and one cross-shaped cross is mounted in a matching way with the buffer slot 5.
Preferably, the dies 9 mounted between the die lips are in a 7-shape, and a horizontal rail 21 at the upper part of the 7-shape is matched with the concave part 22 of the buffer slot 5.
The invention has the beneficial effects that: the PET raw material can be utilized to produce PET polyester flat filaments for producing woven cloth, the woven cloth has the advantages of high strength and long service life, the die head is utilized to produce the PET polyester flat filaments reliably, the quality is stable, the replacement and installation are very convenient during the production of the flat filaments with various specifications, and the production cost is saved.

Detailed Description
The embodiments are described in further detail below with reference to the following figures:
referring to fig. 1 and 3: 1-left module, 2-feeding hole, 3-right module, 4-distribution runner, 5-buffer slot, 6-adjusting screw, 7-die lip elastomer, 8-die orifice, 9-die sheet, 10-strip plate, 31-rectangular through hole, 32-convex rib, a die head for extruding PET polyester flat filament, comprising a left module 1 and a right module 3, wherein the two modules are fastened together by screw, one die lip elastomer 7 of one module is provided with the adjusting screw 6, the die sheet 9 is arranged between the die lip elastomers of the left and right modules, the die sheet 9 is provided with a plurality of rectangular through holes 31 with door openings, the rectangular through holes 31 are uniformly and linearly arranged on the die sheet 9, the upper part of the die sheet 9 arranged between the die lips is provided with the strip plate 10 in a matching way, the strip plate 10 is provided with the convex ribs 32 with the same number as the rectangular through holes 31, the convex rib 32 on the long slat 10 is matched and installed with the rectangular through hole 31 on the die piece 9, the convex rib 32 is matched and installed with the buffer slot 5, the die piece 9 is fastened between two die lip elastomers of the two modules by the adjusting screw 6, when the die head works, a melt enters the distribution runner 4 from the feed port 2 and then enters the plurality of rectangular through holes 31 of the die piece 9 through the buffer slot 5, the melt is sprayed out of a flat plastic strip from a die opening along the rectangular through hole 31, and the flat plastic strip is cooled into a flat strip through a post process and is pulled into a flat wire.
Referring to fig. 2 and 4: 21-transverse die and 22-concave buffer slot, the embodiment of the two figures is different from the embodiment of the two figures in the structure of the die, the die of the embodiment is a 7-shaped die, the effect is the same as that of the first embodiment, and the manufacture of the 7-shaped die is simpler and more convenient than that of a cross die, thereby being beneficial to reducing the manufacture cost and facilitating the replacement.
The invention has the beneficial effects that: the PET raw material can be utilized to produce PET polyester flat filaments for producing woven cloth, the woven cloth has the advantages of high strength and long service life, the die head is utilized to produce the PET polyester flat filaments reliably, the quality is stable, the replacement and installation are very convenient during the production of the flat filaments with various specifications, and the production cost is saved.
