Leather sheet supplying apparatus for thermoforming machine having adjustable pin

Abstract

The present invention provides a leather sheet supplying apparatus which is for a thermoforming machine and has an adjustable pin. Such a leather sheet supplying apparatus, which is for a thermoforming machine and has an adjustable pin, according to the present invention has the technical features in which: a fixing pin, for supporting a lower portion of an edge section of a leather sheet adheredto a door trim material in a step in which the leather sheet is heated, is configured to be positionally adjustable; and the fixing pin is moved in response to a change in the size of the leather sheet caused by the heating, such that the entire section of the leather sheet is uniformly heated and is also uniformly stretched without wrinkling. Therefore, the quality of the formed product is improved, and fabric is saved. In addition, interference between components is prevented during a step for clamping and transferring the leather sheet, thus increasing the driving stability and efficiency of the apparatus. The configuration of the apparatus is also simplified, which helps to improve durability and reduce manufacturing costs.

Description

technical field [0001] This invention relates to a housing supply device for a thermoforming machine equipped with a variable needle, specifically, the heating process of a housing attached to various equipment such as door trim, IP (Instrument Panel), control panel, and roof lining. Among them, the position of the fixed pin at the lower part of the edge of the support shell is variable, and the shell supply device for thermoforming machines with variable pins is constituted. Background technique [0002] Thermoforming machine (Thermoforming machine) is a device used in the manufacture of automotive interior materials. It is used for door trim panels, instrument panels, control panels, headlining, carpets, trunks, etc. of automobiles. In particular, a large number of technologies have been developed for the surface-mounting of door trims of automobiles or instrument panels. [0003] Generally, in the molding device for the door trim or instrument panel of an automobile, the...
