Polyester chip melting device for enhancing material screening effect

Abstract

The invention relates to the technical field of artificial filament manufacturing, and discloses a polyester chip melting device for enhancing a material screening effect. The polyester chip melting device comprises an extrusion cylinder, an inner cavity of the extrusion cylinder is rotatably connected with an extrusion screw rod, the upper end and the lower end of the extrusion screw rod are bothfixedly connected with symmetrical sliding cylinders, storage strips is fixedly connected to the ends, away from the extrusion screw rod, of the sliding cylinders, scraping strips extending to the storage strips are slidably connected to inner cavities of the sliding cylinders, and first springs are fixedly connected between the scraping strips and the inner walls of the sliding cylinders. According to the polyester chip melting device capable of enhancing the material screening effect, the extrusion screw rods drive a transmission disc to rotate, racks drive a threaded toothed rod to rotatein a reciprocating mode, a screening block is matched with a pulley to intermittently extrude a screening plate to vibrate and remove impurities, the first springs enabling the scraping strips to haveelastic allowance are matched, and the first springs are arranged in the sliding cylinders in a sealed mode; and therefore, the service life and the use reliability of a scraping mechanism are improved, and the purity of raw materials is ensured.

Problems solved by technology

[0002] Polyester chips are chips obtained by casting and pelletizing polyester melts. Polyester chips are important intermediates for the production of artificial filaments. At present, when polyester chips are melt-processed and extruded, it is necessary to Correspondingly, the molten material on the inner wall of the extruded barrel is scraped off, but the spring installed on the general scraping mechanism has the problem of direct contact with the molten material. Certain adhesion, so the exposed spring is very unreliable in use. In addition, in the prior art, the purchased polyester chips are directly put into the extrusion equipment, and then melted and extruded. There are certain impurities in the material, so the quality of the extruded material can be guaranteed only when the impurities are fully screened out. Although some extrusion melting devices can remove impurities, the removal rate of impurities is still low, and the purity of the raw materials cannot be guaranteed.

[0003] Aiming at the deficiencies of the prior art, the present invention provides a polyester chip melting device that strengthens the material screening effect, which has the advantages of improving the service life and reliability of the scraping mechanism, ensuring the purity of raw materials, etc., and solves the problem of general The polyester chip melting device has the problems of short service life of the scraping mechanism, unreliable use, and low purity of raw materials during use
