Meanwhile, the above-mentioned partial suction holes 8 may be formed in the lower platen 9, and this is not limited thereto.
In addition, the bottom of the lever 10 is further provided with a plugging plate 14, the plugging plate 14 and the lower pressing plate 9 are arranged on the same side, the workbench 1 is provided with a first plugging groove along the vertical direction, the plugging plate 14 is slidably arranged in the first plugging groove, one side of the plugging plate 14 is hinged to the bottom of the lever 10, the other side of the plugging plate 14 is provided with a plugging spring 15, the plugging spring 15 is connected with the bottom in the first plugging groove, the plugging plate 14 is provided with a first plugging hole 16 corresponding to the first negative pressure channel 4, and the plugging plate 14 is provided with a second plugging hole 17 corresponding to the second negative pressure channel 5. Through the arrangement, when no copper-clad plate is arranged on the workbench 1, the left end of the lever 10 is lifted, and at the moment, the lever 10 drives the plugging plate 14 at the left end to move upwards, so that the first plugging hole 16 is staggered with the first negative pressure channel 4, the second plugging hole 17 is staggered with the second negative pressure channel 5, at the moment, negative pressure suction generated in the negative pressure cavity 3 cannot be transmitted out through the first negative pressure channel 4 and the second negative pressure channel 5, the copper-clad plate is ensured to be placed on the workbench 1 smoothly, and meanwhile, scraps in the first negative pressure channel 4 are also convenient to clean.
Meanwhile, in order to prevent scraps generated by cutting from directly entering the negative pressure cavity 3, a filter screen is arranged in the first plugging hole 16, the first negative pressure channel 4 is also communicated with a slag collecting channel 18, the slag collecting channel 18 is positioned on one side of the plugging plate 14 close to the cutting groove 6, and the bottom of the slag collecting channel 18 is communicated with a slag collecting pool 19. When the scraps are adsorbed to the first negative pressure channel 4 through the cutting groove 6, the scraps are isolated by the filter screen, so that the scraps are prevented from entering the negative pressure cavity 3; after cutting is completed, the scraps directly fall into the slag collecting channel 18 and finally enter the slag collecting tank 19, so that later concentrated cleaning is facilitated.
