Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile carpet, especially relates to a hot pressing and gluing device for automobile carpet. BACKGROUND

[0002] In the production process of automobile carpet, gluing is a crucial step, which involves bonding the carpet with materials such as backing glue to ensure the stability and durability of the carpet during vehicle use. Gluing not only affects the appearance and comfort of the carpet, but also directly relates to the noise control and overall NVH performance of the vehicle. Therefore, the accuracy and efficiency of the gluing process are crucial to the quality of automobile carpet.

[0003] However, during the gluing process, excess glue needs to be squeezed out through pressing or scraping to ensure the effectiveness of the gluing. During the pressing process, excess glue is easily squeezed out from the periphery of the carpet, but due to the uncontrollable direction of overflow, it leads to the difficulty of collecting waste glue, and the random overflow of waste glue not only pollutes the production environment, but also may pollute the carpet itself, resulting in the need for rework or even direct scrap of the carpet, increasing production costs and causing resource waste; during the scraping process, if the operation is not proper, it is easy to cause displacement of the layers of the carpet, which may lead to rework or even direct scrap of the carpet, also increasing the defect rate and cost in the production process. At the same time, pressing or scraping must be carried out before the glue solidifies, otherwise the yield of the carpet will be greatly reduced. CONTENT OF THE INVENTION

[0004] In order to solve the problems of difficult collection of waste glue and poor gluing effect caused by easy solidification of glue in the gluing process of automobile carpet in the prior art, the present application provides a hot pressing and gluing device for automobile carpet, and the specific scheme is as follows:

[0008] When the hot pressing plate rotates downward and is attached to the bottom plate, the two shape memory alloy wires and all the ferromagnetic strips are located in the accommodating groove, and one side surface of the ferromagnetic strip is closely attached to the bottom plate.

[0009] Preferably, the automobile carpet hot pressing and gluing device further comprises a waste glue collecting groove, and the opposite end of the end of the bottom plate hingedly connected with the hot pressing plate is detachably connected with the collecting groove.
