Automatic heat sealing and edge wrapping device for automobile sun visor and preparation method of sun visor

Abstract

The invention discloses an automatic heat sealing and edge wrapping device for an automobile sun visor and a preparation method of the sun visor. The automatic heat sealing and edge wrapping device comprises a power supply box, an edge wrapping mechanism which is electrically connected with the power supply box, and a heat sealing mechanism for heat sealing an upper framework and a lower frameworkwhich are completed by the edge wrapping mechanism; the edge wrapping mechanism comprises a product lower die for placing a foamed polypropylene framework; air cylinder pushing and pressing mechanisms and up-and-down moving and heating parts are arranged around the product lower die and at the four diagonal corners of the product lower die; the air cylinder pushing and pressing mechanisms move towards the product lower die and push fabric to advance towards the periphery and the corners of the foamed polypropylene framework; the up-and-down moving and heating parts can move up and down and cooperate with the product lower die to realize heating and softening; the heat sealing mechanism comprises a first half lower die, a second half lower die, a die assembly mechanism and a heating pressing plate; the first half lower die and the second half lower die can be opened left and right and can be covered with each other after one of the first half lower die and the second half lower die isrotated; the die assembly mechanism drives the second half lower die to rotate and cover the first half lower die; and the heating pressing plate heats and melts the product in advance and can move upand down. The automatic heat sealing and edge wrapping device is simple in structure and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of an automobile sun visor processing machine, in particular to an automatic heat-sealing and wrapping device for an automobile sun visor and a method for preparing the sun visor. Background technique [0002] Automotive interior parts are special-shaped parts that are heat-pressed, composited or coated with various materials. They consist of many parts and soft fabrics, such as car sun visors on cars, vans and luxury vans. In the prior art, the car sun visor is generally formed by injection molding to form a complete skeleton first, and then the technology of edge wrapping is performed, and such a structure needs to be manually wrapped when the side is wrapped, and the side edge wrapping You need to be patient, otherwise it will easily lead to uneven side edge wrapping, which will eventually lead to a serious problem of product scrap rate. Therefore, in order to solve this problem, the company made the skel...

Problems solved by technology

In the prior art, the car sun visor is generally formed by injection molding to form a complete skeleton first, and then the technology of edge wrapping is performed, and such a structure needs to be manually wrapped when the side is wrapped, and the side edge wrapping You need to be patient, otherwise it will easily lead to uneven side edge wrapping, which will eventually lead to a serious problem of product scrap rate. Therefore, in order to solve this problem, the company made the skeleton into two halves, and then hot-pressed the two halves to form a complete skeleton. , but the current automatic heat-sealing and wrapping device for automobile sun visors has a complex structure, and the wrapping still needs manual wrapping, resulting in low work efficiency and complicated operation, so it needs to be improved
