Rotate to complete the cutting of the broad side of the plate; further, a fixed frame is set in this scheme, so that the cutting table can be movably connected to the transport guide rail on the fixed frame. The cutting worktable is driven to move by the worktable driving mechanism. The worktable driving mechanism can be a commonly used driving mechanism in the prior art. Driven by the worktable driving mechanism, the cutting worktable and the plate are kept relatively stationary, and are set in the cutting work. The cutting unit under the table is also relatively stationary with the plate, so that the plate can be cut without stopping the transportation of the transport roller table, without affecting the production and processing efficiency of the plate, and achieving the effect of efficient cutting.

Further, the dust removal unit at the broadside cutting unit includes a broadside cutting dust cover, which is symmetrically arranged above and below the transport roller table to wrap the wideside cutting; A dedusting air hole is provided at the edge cutting, and the dedusting air hole at the wide edge cutting is communicated with a dedusting air duct.

Through the wide-edge cutting dust cover set symmetrically up and down, the wide-edge cutting part can be completely wrapped up and down, and the dust generated during wide-edge cutting will be collected by the wide-edge cutting dust cover, and further openings are opened on the wide-edge cutting dust cover. The dust removal air hole at the wide edge cutting connects the dust removal air duct of the dust removal mechanism usually installed in the workshop with this air hole, so that the dust collected by the wide edge cutting dust removal hood will pass through the wide edge cutting. It is extracted and removed by the dust removal air duct, and no dust will escape into the workshop during the wide-edge cutting process, so as to achieve the effect of dust-free cutting there.

Further, the cutting unit includes:

The cutting mechanism, which is a motor-driven saw blade, is located just below the cutting opening of the saw blade, and the cutting mechanism passes through the cutting opening of the saw blade to complete the cutting action on the plate;

The traverse mechanism, which is connected with the cutting mechanism in a transmission type, drives the cutting mechanism to move along the direction of the cutting opening of the saw blade;

On the premise of not affecting the smooth movement of the saw blade during the cutting process, the width of the avoidance notch can be reduced as much as possible, thereby ensuring the sealing and reducing the dust falling on the surface of the plate, which is convenient for dust removal. The operation is carried out to improve the dust removal effect. According to the test analysis, the effect is the best when the width of the control avoidance notch is greater than the width of the saw blade of the cutting mechanism by 3-6mm.

Further, both ends of the dedusting pressure cover are provided with upper dedusting air holes to communicate with the dedusting air duct.

Both ends are provided with dust removal air holes to communicate with the dust removal air duct to further strengthen the dust removal effect.

Further, an extension roller table is fixedly connected to the end of the cutting table away from the transport roller table, which is arranged in the same direction as the transport roller table.

After the cutting is completed, the worktable drive mechanism needs to drive the cutting worktable to return to the initial position, that is, the position where it contacts the end of the transport roller table. At this time, under the force of the abutment of the plates on the transport roller table, the cut part of the plate is relatively The cutting table will move in the direction away from the transport roller table, and the extended roller table can prevent the cut sheet from falling, and can guide the sheet to enter the finished product collection station smoothly, so as to achieve the purpose of automatic unloading.
