Manufacturing system and method based on hot-pressing-resistant PET (Polyethylene Terephthalate) polyester bottle

Abstract

The invention discloses a manufacturing system and method based on a hot-pressing-resistant PET polyester bottle. The manufacturing system comprises a base station, crushing mechanisms arranged on the right side and the left side of the upper part of the base station, a granulation mechanism and a sterilization mechanism arranged on the left side of the interior of the base station, wherein the granulation mechanism comprises a blanking box body, a blanking hopper and a return tube; the bottom of the blanking hopper penetrates through the upper portion of the blanking box body. The invention relates to the technical field of PET polyester bottle manufacturing. According to the manufacturing system and method based on the hot-pressing-resistant PET polyester bottle, when an outer roller rotates, an inner column is fixed, and the outer roller drives the granulation groove to rotate to the position below the inner column, a semi-oval structure on the lower portion of the inner column enables the ejector pin to eject PET particles adsorbed in the granulation groove through the push rod; and meanwhile, the brush scrapes away the residual PET particles in the granulation groove, so that the scraping effect is good; and the PET particles adhered to the outer roller are prevented from influencing the subsequent production of the PET polyester bottle, and thus, the quality of the PET particles is prevented from being reduced to affect the subsequent production of the PET polyester bottle.

Description

technical field [0001] The invention relates to the technical field of manufacturing PET polyester bottles, in particular to a manufacturing system and method based on heat and pressure resistant PET polyester bottles. Background technique [0002] In the field of PET polyester bottle processing, various masterbatches need to be crushed before injection molding and then granulated, and the effective granulation is screened for subsequent processing. When the existing polyester bottle is expected to be produced, its processing device exists The following questions, [0003] 1) During granulation, the PET raw material is often easily stuck in the granule tank, and the PET raw material cannot be discharged, resulting in a decrease in the production efficiency of the subsequent granules, and repeated extrusion, which reduces the quality of the PET granules; [0004] 2) The quality of PET granules is uneven, which in turn affects the qualified rate of ET polyester bottle product...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a manufacturing system and method based on heat-resistant and pressure-resistant PET polyester bottles, which solves the problem of low efficiency of the expected production device and easy occurrence of material jams, resulting in low quality and low pass rate. At the same time, the integrated operation of the system cannot be realized, thus increasing the labor intensity of the workers
