[0024] Reference Figure 1 , Figure 2 A diffusion plate cutting device includes a cutting table 1, a cutting machine 2 is arranged on the cutting table 1, the interior of the cutting table 1 is hollow and forms a support cavity 3, a plurality of air holes 4 are evenly opened on the upper surface of the cutting table 1, and the plurality of air holes 4 are respectively connected to the support cavity 3. At the same time, a blowing mechanism 5 is arranged on the cutting table 1, and the blowing mechanism 5 is used to blow cold air into the support cavity 3 so that the cold air is discharged through the plurality of air holes 4 and the formed plate and scraps are blown up. In the present application, the formed plate is defined as: the target plate after the diffusion plate is cut into the required size.
[0025] When cutting is required, the blank sheet is placed flat on the cutting table 1, and then the blank sheet is cut into the required size by the cutting machine 2. Subsequently, cold air is blown into the support cavity 3 by the air blowing mechanism 5, and the cold air is discharged through a plurality of air holes 4, and blows up the formed sheet and the scraps, so that the formed sheet and the scraps are quickly separated from the cutting table 1. This design can facilitate the production personnel to sort the formed sheet and the scraps, which can not only improve the convenience of operation, but also improve the production efficiency.
