Working principle: when the vacuum insulation panel 4 is transported to the bottom of the first support 5 by the conveyor belt 3, the temperature collection module 24 collects the temperature of the vacuum insulation panel 4 and the ambient temperature, and feeds back to the DATA-7311 controller 2 to control The controller 2 processes the detected temperature, and feeds back the processing result to the variable temperature adjustment module 20, sets the pressure threshold on the controller 2, and the JY-LCS1 pressure sensor 13 detects the received pressure in real time and transmits it to the controller 2 , the controller 2 starts the driving motor 17, and the rotating shaft 14 drives the fixed shaft 23 to rotate through the belt pulley 16. Since the nut blocks 15 on both sides of the casing 18 are respectively threaded with the rotating shaft 14 and the fixed shaft 23, the nut block 15 is limited by the casing 18. The rotation cannot occur, so that the nut block 14 drives the housing 18 to move downward, so that the data acquisition module 21 moves to the surface of the vacuum insulation panel 4 and fully contacts with the vacuum insulation panel 4. When the pressure value reaches the set pressure, the controller 2. Control the drive motor 17 to turn off, so as to achieve precise control, and realize that the contact force of products with different thicknesses is consistent.
