When it is necessary to automatically feed the processing plate, the processing plate is first placed on the surface of the conveyor belt 3, and then the motor 4 is turned on, and the output end of the motor 4 drives the rollers 2 to rotate, and the rollers 2 rotate while driving the conveyor belt 3 to rotate, and the conveyor belt 3 drives the processing plate on the surface to move, and the processing plate can be pressed down and limited by the downward pressing component to ensure the stability of the processing plate during cutting, and the processing plate can be limited by the limiting component to ensure that the processing plate moves in a straight line, thereby achieving the effect of automatic feeding.

[0020] Reference Figure 1 and Figure 2 As shown, in this embodiment: the limiting assembly includes a bidirectional screw 6, both ends of the bidirectional screw 6 are rotatably connected to the surface of the fixed frame 5, and one end of the bidirectional screw 6 passes through the side wall of the fixed frame 5 and is fixedly connected to a turning handle 7, the surface of the bidirectional screw 6 is threadedly connected to two push frames 8, and the lower ends of the two push frames 8 are fixedly connected to a limiting frame 9, by rotating the turning handle 7, the turning handle 7 drives the bidirectional screw 6 to rotate, and the rotation of the bidirectional screw 6 drives the two limiting frames 9 at the lower ends of the push frames 8 to move, which can change the distance between the two limiting frames 9, so that processing plates of different widths can be limited, the inner wall of the limiting frame 9 is rotatably connected to a plurality of rotating drums 10, and the plurality of rotating drums 10 are equidistantly arranged, and by setting the rotating drums 10, the sliding friction between the processing plate and the limiting frame 9 can be converted into rolling friction, thereby reducing friction and making the processing plate move more smoothly.

[0021] Reference Figure 1 Figure 3 and Figure 5As shown, specifically, the pressing assembly includes a pressing frame 12 and a sliding rod 17. The pressing frame 12 is rotatably connected to one end of the fixed plate 11, and the surface of the pressing frame 12 is rotatably connected to a push rod 14, one end of the push rod 14 is slidably connected to a slide cylinder 15, and the upper end of the slide cylinder 15 is fixedly connected to the lower surface of the fixed plate 11, a spring A16 is arranged in the slide cylinder 15, one end of the spring A16 is fixedly connected to the push rod 14, the sliding rod 17 is slidably connected to the other end of the fixed plate 11, the lower end of the sliding rod 17 is fixedly connected to a pressing plate 18, a spring B19 is arranged between the pressing plate 18 and the sliding rod 17, and the spring B19 is slidably connected to the surface of the sliding rod 17, when one end of the processing plate passes through the pressing frame 12, the pressing wheel 13 at the lower end of the pressing frame 12 will squeeze the processing plate to enhance stability, and at the same time the pressing frame 12 will push the push rod 1 4 squeeze spring A16, to prevent the pressure wheel 13 from over-squeezing, resulting in excessive friction and the processing plate being unable to move. When one end of the processing plate is transported to the lower end of the pressure plate 18, the processing plate will push the pressure plate 18 upward to squeeze the spring B19. The reaction force generated by the elastic deformation of the spring B19 squeezes the processing plate to prevent its position from shifting when it moves. The pressure plate 18 and the pressure wheel 13 are used to limit both ends of the processing plate at the same time to ensure the stability of the processing plate during cutting. The two sides of one end of the conveying frame 1 are rotatably connected with guide rods 20, and the upper end of the guide rod 20 is threadedly connected with a fixing bolt 21. By setting the guide rod 20 and the fixing bolt 21, the angle of the guide rod 20 can be adjusted to guide the processing plate, so that it can more easily enter between the two limit frames 9.

[0022] Working principle: first, by rotating the handle 7, the handle 7 drives the bidirectional screw 6 to rotate. When the bidirectional screw 6 rotates, it drives the two limit frames 9 at the lower end of the push frame 8 to move, and the distance between the two limit frames 9 can be changed, so that the processing plates of different widths can be limited, and at the same time, the processing plates can be moved in a straight line, so as to achieve the effect of automatic feeding. Then the processing plate is placed on the surface of the conveyor belt 3, and then the motor 4 is turned on. The output end of the motor 4 drives the roller 2 to rotate. When the roller 2 rotates, it drives the conveyor belt 3 to rotate. The conveyor belt 3 drives the surface processing plate to move. When one end of the processing plate passes through When passing the pressure frame 12, the pressure wheel 13 at the lower end of the pressure frame 12 will squeeze the processing plate to enhance stability. At the same time, the pressure frame 12 will push the push rod 14 to squeeze the spring A16 to prevent excessive squeezing of the pressure wheel 13, which will cause excessive friction and the processing plate cannot move. When one end of the processing plate is transported to the lower end of the pressure plate 18, the processing plate will push the pressure plate 18 upward to squeeze the spring B19. The reaction force generated by the elastic deformation of the spring B19 will squeeze the processing plate to prevent its position from shifting when it moves. The stability of the processing plate during cutting can be guaranteed by limiting the two ends of the processing plate by the pressure plate 18 and the pressure wheel 13 at the same time.
