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; an aspiration pipe adapting port is connected with the top of the box cover in a matching way; 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 hot air generation mechanism is connected with the airflow circulation mechanism by a pipeline; and the airflow circulation mechanism comprises a working motor, a fan, an aspiration pipe, an air supply pipe, a connection cotton box and a cotton guide box. The automotive upholstery pre-shaping machine adopting the air filling method has the advantages that the quality of automotive upholsteries which are pressed and shaped by subsequent pressing processes can be reliably guaranteed, the overall structure is simple, and the labor intensity is decreased for workers; the processing efficiency is high and the energy is saved; and in addition, fibers with a low melting point are vitrified, so that the prototypes of the automotive upholsteries are formed.

Description

technical field [0001] The invention belongs to the technical field of production devices for vehicle interior parts, in particular to an air-filling preforming machine for vehicle interior parts. Background technique [0002] Vehicle interior parts, such as floor mats and sound insulation felts located in the front and rear driving positions of the vehicle 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, cotton fibers, etc.) fiber, viscose fiber and wool fiber mixed with one or more fibers), or chemical fiber (such as polyester fiber, nylon fiber and acrylic fiber mixed with one or more fibers) 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 CN101549671A (hemp fiber automotive in...

AI Technical Summary

Problems solved by technology

[0005] The following technical problems will inevitably occur under the situation of producing automotive interior parts by means of a web-laying machine or similar equipment: First, although the thickness requirements for the same vehicle interior part can be determined by the subsequent molding die (compression die) The structure is guaranteed, but the consistency of the density of the same vehicle interior part cannot be guaranteed, thereby affecting the product quality of the vehicle interior part; secondly, either a lot of equipment is invested (such as CN101549671A), or the structure of the equipment is extremely complicated ( Such as CN101775708A); Third, the molding efficiency is low, not enough to meet the requirements of industrial mass production
