The working process of the device is as follows:
referring to fig. 1B-7B, in a production operation, the cutting process may begin by laying the flexible facestock 100 flat on the platform 2. At this time, the exhaust fan 8 also starts to exhaust air, and air above the platform 2 is sucked into the air collecting channel 25 at the bottom of the platform 2 through the surface material 100, the non-woven fabric 23, the grid 22 and the valve block array layer 21 and collected into the air collecting pipe 24 to be exhausted by the exhaust fan 8, so that negative pressure is generated between the surface material 100 and the platform 2 to adsorb and attach the surface material to the platform 2 so as to prevent the surface material from moving in the cutting process. Along with the movement of the tool bit 6 on the bearing platform 2 according to the designed processing track, the X-axis driving module and the Y-axis driving module 5 drive the valve driving top plate 79 of the valve driving module 7 through the X-axis threaded slider 37 and the Z-axis driving rod 72 respectively to follow the current position of the tool bit 6 in real time. When the valve driving top plate 79 of the valve driving module 7 moves to a certain position along with the cutter head, the valve stem 2111 in the valve block 211 near the cutter head in the bearing platform 2 is jacked up by the valve driving top plate 79 of the valve driving module 7 to open the air valve 2113, the upper part of the valve block is communicated with the air collecting channel 25 through the air valve 2113, the downward air flow velocity passing through the bearing platform is the maximum, and therefore the negative pressure adsorption force of the blocky local area near the cutter head on the bearing platform 2 is also the maximum; and the valve stem 2111 in the valve block 211 far away from the cutter head 6 in the bearing platform 2 closes the valve 2113 under the action of the valve spring 2112 to block the airflow channel, so that the negative pressure adsorption on the bearing platform 2 is mainly limited to a block-shaped area which is cut near the current position of the cutter head, and the air draft power consumption of the exhaust fan can be greatly reduced.
