Embodiment

[0032] It includes the following steps:

[0033] A. Baking and pressing: Put the fabrics required for car carpet production into the oven to bake, adjust the temperature, close the upper layer of the oven, control the lower layer to 240±20°C, and bake for 200±20S; Take it out of the oven and buckle it on the mold for molding. The pressure holding time is 40±5s. After the mold is opened, wait for the carpet to cool for 20s before taking out the molded carpet. At the same time, be careful not to let the nails on the mold hook on the carpet. Remove the inside of the mold. Residue; put the pressed carpet on the tooling rack to cool and shape, and after cooling on the tooling rack, place the carpet on the cart, and accumulate no more than 10 carpets;

[0034] B. Sticking protective film: It is completed by two operators, located on both sides of the carpet, one is responsible for pulling and laying, and the other is responsible for cutting with a blade, so that the protective film ...

Abstract

The invention discloses a method for pasting a protective film of an automobile carpet, and relates to the technical field of automobile spare parts manufacturing. It includes baking and pressing, sticking protective film, foaming in the carpet mold, water cutting edge cutting and hole cutting, and pasting EPP gaskets. In the invention, the carpet protective film is pasted first and then foamed, and the pressure of the press in the foaming process and the pressure generated by the foaming material in the foaming process are used to increase the contact area between the carpet suede and the carpet protective film, and increase their bonding strength. , so as to solve the problem of falling off of the carpet protective film due to insufficient bonding strength between the carpet protective film and the needle-punched carpet in the existing automobile carpet protective film sticking technology.

Description

technical field [0001] The invention relates to the technical field of automobile spare parts manufacturing, in particular to a process method for pasting a protective film of an automobile carpet. Background technique [0002] Car carpets are installed on the floor of the vehicle interior to play the role of shock absorption, noise reduction, heat insulation, etc., and are the main products of automotive interior parts. Car carpets generally use needle-punched fabrics as raw materials. During production, transportation and installation, the suede surface of needle-punched carpets is easy to get dirty, especially at the foot position, so it is necessary to paste a layer of carpet protective film on this position. However, because the prior art is usually to paste the carpet protective film after the water cutting is completed, and the carpet protective film is only adhered to the suede surface of the needle-punched carpet, the contact area between the two is small, and the b...
