Honeycomb-shaped fabric composite thermoplastic sheet and machining method for molding case shell of trolley case through compression molding

Abstract

The invention discloses a honeycomb-shaped fabric composite thermoplastic sheet and a machining method for molding a case shell of a trolley case through compression molding, and relates to the technical field of production of trolley cases. The machining method comprises the following three steps: machining of a honey-shaped fabric: yarns are treated in a warping procedure, and are woven as the honey-shaped fabric; and finally, the honey-shaped fabric is shaped and coiled by a hot air type oven; machining of a composite sheet: the shaped honey-shaped fabric and a molten sheet extruded by a screw extruder are extruded by two rollers to form an embedded composite sheet for cooling and coiling; and then, the composite sheet and the extruded molten sheet are extruded and bonded by two rollers again to form a sandwich-structured composite sheet; and molding of the case shell: the sandwich-structured composite sheet is molded by hot pressing through a mold to prepare the case shell of the trolley case. The machining method has the following beneficial effects: the honeycomb-shaped fabric and the thermoplastic sheet are compounded by hot pressing to form the sandwich thermoplastic composite sheet structure; and the case shell of the trolley case is prepared through the composite sheet, so that the trolley case is high in strength and not easy to crack.

Description

technical field [0001] The invention relates to the technical field of trolley case production, in particular to a processing method for a honeycomb fabric composite thermoplastic sheet and a compression molded trolley case shell. Background technique [0002] With the acceleration of the pace of work and life and the continuous changes in the mode of transportation, people travel more and more, and more and more business people choose hard trolley cases as a travel tool. The most common problems in the use of the trolley case are that the case is too heavy, it is inconvenient to carry, and the case is cracked and the items are scattered due to high-strength extrusion during long-term use and consignment, which affects the convenience of the trolley case. [0003] The materials of the hard trolley case are mainly polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), polypropylene (PP) and the like. At present, the trolley cases on the market are constantly tr...

Problems solved by technology

But there are two main problems with this method: first, carbon fiber is heavy and expensive; second, the processing time of epoxy resin molded trolley case is long and the efficiency is low

There are two problems with this method: First, the solvent impregnation increases equipment investment, the post-processing is complicated, and the cost is high; second, the glass fiber cloth is generally stretched uniaxially, and the reinforcement effect is not good
