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 present invention is the technology field of vehicle interior production device, which involves a pre -forming machine of the vehicle interior part of the air filling method. Background technique [0002] Vehicle interior components such as floor mats and sound insulation felt in the positive and auxiliary rack of the vehicle frame, etc., usually the thermoplastic fibers of the low melting point such as proparbly fiber, the thermoplastic fiber of the low melting point and the natural fiber (such as hemp fiber, cotton cotton, cotton cotton, cottonOne or more fiber mixed fiber in the fiber, adhesive fiber and wool fiber, or mixes or more with chemical fiber (such as polyester fiber, nylon fiber and acrylic fibers (mixed with fiber -phase fibers in mixed fibers).Obtained by heating and suppression. [0003] China Invention Patent Application Number CN101775708A recommends that there is an automatic molding machine for automotive interior components. The pa...

Problems solved by technology

[0005] In the case of producing automotive interior parts by means of a web-laying machine or similar equipment, the following technical problems inevitably occur: First, for the same vehicle 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 vehicle interior part cannot be guaranteed, thereby affecting the product quality of the vehicle 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

Therefore, whether the structure of the hot air generating mechanism or the hot air generating mechanism is reasonable or not will have an impact on the effect of the whole machine. However, in the Chinese and foreign patents and non-patent literature disclosed so far, there is no such thing as the air-filling method for the pre-preparation of vehicle interior parts. The technical information of the overall structure of the forming machine has not disclosed the corresponding technical content of the hot air generating mechanism that can be matched with it. Therefore, the applicant has made positive and beneficial attempts. The technical solution to be introduced below is against this background
