The positioning device is connected with the fixing device, the power device is in transmission connection with the positioning device, the fixing device comprises an objective table and a mounting seat, the objective table and the mounting seat are provided with a support, the objective table is fixedly connected with the support, the mounting seat is movably connected with the support, a plurality of clamping seats are arranged on the lower side of the mounting seat, wedge grooves are formed in the clamping seats, and the wedge grooves face the upper layer side line of the decorative plate. The objective table is provided with a plurality of clamping grooves, the clamping grooves face the sideline of the lower layer of the decorative plate and limit the lower layer of the decorative plate, the clamping base limits the upper layer of the decorative plate through the wedge groove, and the surface of the decorative plate is prevented from being damaged through sideline limiting.

Description

technical field [0001] The invention relates to the technical field of strength detection of a composite layer of a decorative board, in particular to a device for testing the bonding strength of a composite layer of a decorative board. Background technique [0002] With the continuous development of the construction industry, the requirements for composite laminates are becoming more and more diverse. Decorative panels are one of the new panels in the construction industry. By adding decorative panels to the wall, the overall aesthetics of the building can be improved, making the building more popular. welcome.

Problems solved by technology

[0003] However, decorative boards are often made of multi-layer boards. Due to the high temperature of the melt glue, it has certain fluidity and cannot guarantee uniform glue application. Therefore, when large-scale boards are glued together, it is easy to cause voids in the composite layer of the decorative board. , resulting in insufficient bonding. In the long-term use process, due to changes in air temperature and humidity, it is easy to cause degumming and affect the service life

[0004] The adhesive performance of the composite layer of the decorative board now mostly adopts the impact test, but many decorative boards are built-in design, and the impact load is less in the process of use, so the bond strength test through the impact is likely to lead to inaccurate detection. In addition , when the decorative panel is manufactured, the impact test will cause damage to the decorative panel

The surface of the decorative board is designed with a pattern, which will also damage the surface pattern during the clamping process and affect the product quality
