Even if the panel material can cover the grid cap tightly, the slit generated after the panel material is cut will cause air leakage, and the negative pressure adsorption effect will be reduced. The current cutting machine generally divides the air extraction cavity at the lower part of the grid-type bearing platform into a plurality of independent compartments and is respectively connected with the exhaust fan through electromagnetic valves, and in the cutting process, a control system dynamically opens the electromagnetic valves communicated with the compartments adjacent to the bearing platform below the bearing platform according to the current position of the cutting tool bit, so that the air leakage of the bearing platform in negative pressure adsorption can be reduced, the power of the exhaust fan is reduced, and hundreds of electromagnetic valves which are needed to be adopted inevitably bring the defects of complex control system, high equipment manufacturing and maintenance cost, high operation noise and the like.
Still another type of cutting machine design scheme adopts a shade curtain which is dynamically opened and closed along with the movement of a cutting tool bit, the design reduces the air leakage of a bearing platform in the cutting process to a certain extent, is beneficial to reducing the number of independent compartments at the lower part of the bearing platform, reduces the power of an electromagnetic valve and an exhaust fan, and accordingly reduces the equipment cost, the complexity of a control system, the production running noise and the energy consumption, but the dynamic opening and closing shade curtain design still has the defect of complex equipment structure.
In order to solve the above-mentioned shortcomings of the existing flexible sheet cutting equipment, a cutting machine with simpler structure, lower manufacturing cost, good negative pressure adsorption effect, low noise and low energy consumption in production and operation is needed.

The working process of the equipment is as follows:
Referring to fig. 1B-7B, the dicing process may begin by spreading the flexible facestock 100 over the platform 2 during the production operation. At this time, the exhaust fan 8 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 plane material 100, the non-woven fabric 23, the grid 22 and the valve block array layer 21 and collected into the air collecting tube 24, so that negative pressure is generated between the plane material 100 and the platform 2 to adsorb and attach the plane material on the platform 2, and the plane material is prevented 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 to follow the current position of the tool bit 6 in real time through the X-axis threaded sliding block 37 and the Z-axis driving rod 72 respectively. 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 rod 2111 in the valve block 211 near the cutter head in the bearing platform 2 is jacked by the valve driving top plate 79 of the valve driving module 7 to open the valve 2113, the upper part of the valve block is communicated with the gas collecting channel 25 through the valve 2113, the downward air flow velocity passing through the bearing platform is maximum, so that the negative pressure adsorption force of the block-shaped local area near the cutter head on the bearing platform 2 is also maximum; the valve rod 2111 in the valve block 211 far away from the tool bit 6 in the bearing platform 2 closes the valve 2113 under the action of the valve spring 2112 to block the air flow channel, so that the negative pressure adsorption on the bearing platform 2 is mainly limited to the block-shaped area which is being cut near the current position of the tool bit, and the exhaust power consumption of the exhaust fan can be greatly reduced.
