[0023] Connecting mechanism 6: respectively arranged at the lower end of the telescopic end of the electric push rod 5, a pressing plate 7 is arranged between the lower ends of the connecting mechanism 6, which is convenient for applying pressure to the multilayer board, and the connecting mechanism 6 includes a cylinder 61, a connecting column 63 and a limiting column 65, the cylinder 61 is respectively arranged at the lower end of the telescopic end of the electric push rod 5, and the sliding hole at the lower end of the outer arc surface of the cylinder 61 is slidably connected to the limiting column 65, the connecting column 63 is respectively arranged on the upper surface of the pressing plate 7, and the discs at the upper ends of the connecting columns 63 are respectively inserted into the interior of the cylinder 61, and the discs at the upper ends of the connecting columns 63 are installed in coordination with the limiting column 65. After the discs at the upper ends of the connecting columns 63 enter the interior of the cylinder 61, the limiting column 65 is moved to make the limiting column 65 contact with the lower surface of the discs at the upper ends of the connecting columns 63, and the limiting column 65 is moved to contact with the lower surface of the discs at the upper ends of the connecting columns 63. The cooperation of the cylinder 61 limits the upper and lower positions of the connecting column 63.

[0024] The working principle of a multi-layer board pressing machine provided by the utility model is as follows: in the production process of multi-layer boards, multiple raw material boards are overlapped and placed on the surface of the placing plate 10, and the electric push rod 5 is started by the PLC controller 9. The telescopic end of the electric push rod 5 drives the pressing plate 7 to move downward, exerts pressure on the raw material boards, and presses the multi-layer boards. When the pressing machine is used, when it is necessary to replace the pressing plate 7, it is only necessary to rotate the conical tube 64, and the conical tube 64 is threadedly connected to the cylinder 61 to move the conical tube 64 upward. As the conical tube 64 moves upward, the moving range of the limit column 65 gradually increases. Under the elastic force of the spring 66, the limit column 65 moves in the direction away from the connecting column 63, and the limit column 65 no longer contacts the disc at the upper end of the connecting column 63, providing space for the connecting column 63 to leave the inside of the cylinder 61, and the connecting column 6 3 is pulled out from the cylinder 61, and the pressing plate 7 is replaced. After the replacement is completed, the above operation is repeated in reverse, and the conical inner arc surface of the conical tube 64 is used to apply a force to the limiting column 65, so that the limiting column 65 overcomes the elastic force of the spring 66 and moves toward the direction close to the connecting column 63, so that the limiting column 65 contacts the lower surface of the disk at the upper end of the connecting column 63. Through the cooperation between the limiting column 65 and the cylinder 61, the upper and lower positions of the connecting column 63 are limited. At the same time, the plug column 62 is inserted into the plug hole at the upper end of the connecting column 63 to limit the rotation of the plug column 62. According to the size of the pressing plate 7, the motor 8 can be started, and the output shaft of the motor 8 drives the screw rod 3 to rotate. Under the limitation of the bracket 2, the two sliders 4 are driven to move relative to each other through the threaded connection between the screw rod 3 and the slider 4, and the spacing between the two electric push rods 5 is changed, so that the pressing machine can install pressing plates 7 of different sizes.
[0025] It is worth noting that the PLC controller 9 disclosed in the above embodiment can use the NX7 model PLC controller, the electric push rod 5, the motor 8 and the pressure sensor 11 can be freely configured according to the actual application scenario, the electric push rod 5 can use the ANT-52 model electric push rod, the motor 8 can use the 3M57-42A model stepper motor, the pressure sensor 11 can use the DJYL-SX model pressure transmitter, and the PLC controller 9 controls the operation of the electric push rod 5, the motor 8 and the pressure sensor 11 using methods commonly used in the prior art.
