The pneumatic pressure roller assembly 103, the chamfering blade assembly 104, and the side guard wheel frame 105 are respectively mounted on the first support 101 and the second support 102. A processing platform is located in the center of the base. The first and second supports are located on the left and right sides of the processing platform, respectively. A belt and belt drive mechanism are installed on the processing platform. The material to be processed is placed on the belt and held by the side guard wheel frames 105 on both sides. The pneumatic pressure rollers 134 of the pneumatic pressure roller assembly 103 press the material from above. As the belt drives the material forward, the chamfering blade assembly 104 operates, continuously cutting and processing the four corner edges of the material. A screw and nut mechanism is installed between the first bracket and the base. The distance between the first bracket and the second bracket is adjusted by the screw and nut mechanism to accommodate the chamfering of plates of different widths.

When the plate to be machined is placed on the belt and the distance between the first support and the second support is adjusted to a suitable position, the edge part of the plate to be machined is placed above the lower positioning disc 140. At this time, due to the gravity of the plate and the pressure of the pneumatic pressure wheel 134, the lifting spring is compressed, so that the upper quadrant point of the lower positioning disc 140 is on the same horizontal plane as the belt. The distance between the lower tool motor support and the bottom plate of the tool set support 149 is adjusted by a support hand wheel 148. The support hand wheel 148 is adjusted to move the lower tool motor support in the vertical direction of the tool set support 149, so that the upper positioning disc 141 is pressed on the upper surface of the plate to be machined. At this time, one side of the upper positioning wheel 143 and the lower positioning wheel 142 abuts against the side wall of the plate to be machined, and the plate to be machined is clamped and positioned in the vertical and horizontal directions. The second motor processes the corner of the plate to be machined to form a chamfer or an inclined angle. The upper tool and the lower tool are installed on the shaft end of the second motor shaft, and the second motor shaft cooperates with the blade shape of the tool to be machined and is arranged at an angle of 45 degrees. A feed amount fine adjustment mechanism is arranged between the second motor and the motor support, so that the cutting depth of the chamfer can be fine adjusted.
