Automotive upholstery pre-shaping machine adopting air filling method

Abstract

The invention provides an automotive upholstery pre-shaping machine adopting an air filling method, belonging to the technical field of automotive upholstery production devices. The automotive upholstery pre-shaping machine adopting the air filling method comprises a pre-shaping box, an airflow circulation mechanism, a fiber weighing and measuring mechanism, a fiber conveying mechanism and a hot air generation mechanism, wherein a box cover is formed on the top part of the pre-shaping box; a box chamber opening / closing mechanism is arranged on one side of the pre-shaping box; a pre-shaping mould is arranged on the top of a box chamber; an aspiration hole is opened in the pre-shaping mould; a fiber feeding mechanism is arranged on the bottom of the pre-shaping box; the airflow circulation mechanism is connected with the box cover in a matched way, and further stretches to the bottom of a pre-shaping box frame; the fiber weighing and measuring mechanism is arranged on the terrace of a use place or configured on a support on the terrace; the fiber conveying mechanism is connected with the fiber weighing and measuring mechanism, and connected with the airflow circulation mechanism as well; and the hot air generation mechanism is connected with the airflow circulation mechanism by a pipeline. The automotive upholstery pre-shaping machine adopting the air filling method has the advantages that the density of a fiber cotton layer which is adsorbed onto the pre-shaping mould can be enabled to be consistent; the overall structure is simple, and moreover, the ideal automation degree can be reflected, and the labor intensity is decreased for workers; and additionally, the processing efficiency is ideal and the energy is saved.

Description

technical field [0001] The invention belongs to the technical field of production devices for automotive interior parts, and in particular relates to an air-filling preforming machine for automotive interior parts. Background technique [0002] Automotive interior parts, such as floor mats and automotive sound insulation felts located in the front and rear driving positions of the car frame cab, are usually made of low-melting thermoplastic fibers such as polypropylene fibers, low-melting thermoplastic fibers and natural fibers (such as hemp fibers, Blended fiber mixed with one or more fibers of cotton fiber, viscose fiber and wool fiber), or mixed with chemical fiber (such as one or more fibers of polyester fiber, nylon fiber and acrylic fiber) ) obtained by heating and pressing. [0003] Chinese Invention Patent Application Publication No. CN101775708A recommends a felt automatic molding machine for automotive interior parts. This patent application scheme makes up for CN...

Problems solved by technology

[0005] Under the situation of producing automotive interior parts by means of a web lapper or similar equipment, the following technical problems inevitably occur: First, for the same automotive interior parts Although the thickness requirements can be guaranteed through the structure of the subsequent molding die (pressing die), the consistency of the density of the same automotive interior part cannot be guaranteed, thereby affecting the product quality of the automotive interior part; There are a lot of equipment (such as CN101549671A), or the structure of the equipment is extremely complicated (such as CN101775708A); third, the molding efficiency is low, which is not enough to meet the requirements of industrial mass production
