Technical Field
[0001] This utility model relates to the field of automotive carpet processing technology, and in particular to a carpet plastic part welding device. Background Technology
[0002] Carpets are floor coverings made from natural fibers such as cotton, linen, wool, silk, and grass, or chemically synthesized fibers, through hand or machine processes of weaving, tufting, or spinning. They are used to cover the floors of residences, hotels, stadiums, exhibition halls, vehicles, ships, and airplanes, providing noise reduction, heat insulation, and decorative effects.
[0003] However, plastic parts are welded to the surface of the carpet inside the car. Because the carpet inside the car is of different shapes and sizes, the carpet is not fixed during the welding process, which can easily lead to misalignment of the plastic parts. At the same time, the unevenness of the carpet inside the car makes it inconvenient to support the welding position of the plastic parts. Therefore, we have developed a carpet plastic part welding device. Utility Model Content
