A scale 6 is provided, and a driving roller 7 for limiting the plate is provided on the side of the top of the base box 1 away from the baffle frame 3. Both ends of the driving roller 7 are rotatably connected to the mounting box 8 through bearings. A vertical second through slot is opened on the front and back of the base box 1. The opposite side of the mounting box 8 passes through the second through slot and extends to the interior of the base box 1. A first electric push rod 9 is fixed to the top of the inner cavity of the base box 1. The piston rod of the first electric push rod 9 is fixedly connected to the mounting box 8. The inner cavity of the mounting box 8 is provided with a driving assembly 10 for driving the driving roller 7;

[0022] The baffle frame 3 is driven to move on the top of the machine base box 1 through the adjustment component 5, and the distance between the baffle frame 3 and the cutting equipment 2 is adjusted in conjunction with the scale 6 to facilitate fixed-length cutting. Then the first electric push rod 9 drives the installation box 8 to move up and down, and the drive roller 7 is used to clamp and limit the plates of different thicknesses to ensure that the plates are tightly attached to the top of the machine base box 1 during cutting to prevent shaking due to cutting and ensure the stability of plate cutting.

[0023] The cutting equipment 2 includes a mounting frame 201 movably arranged in the inner cavity of the base box 1, and a servo motor 202 is installed on one side of the mounting frame 201. The output shaft of the servo motor 202 passes through the mounting frame 201 and is fixed with a cutting blade 203. A second electric push rod 204 is fixed to the back of the base box 1, and the piston rod of the second electric push rod 204 passes through the inner cavity of the base box 1 and is fixedly connected to the mounting frame 201. A third through slot is provided on the top of the base box 1, and the cutting blade 203 passes through the third through slot and extends upward. The mounting frame 201 is driven by the second electric push rod 204 to move back and forth, so that the cutting blade 203 can be used to cut the plate from back to front.

Through the setting of the limit plate 12, it is convenient to cooperate with the baffle frame 3 to limit the stability of the plate on the top of the base box 1, thereby preventing the cutting blade 203 from contacting the plate and cutting, causing the plate to move.

[0028] When in use, the plate is placed on the top of the base box 1, with one side attached to the limit plate 12, and then the first electric push rod 9 drives the installation box 8 to move down, so that the installation box 8 and the driving roller 7 move down to limit the plate, so that the plate is close to the top of the base box 1, and then the driving motor 101 is started, and the driving motor 101 drives the driving pulley 102 to rotate, and then the connecting belt 104 is used to drive the driven pulley 103 and the driving roller 7 to rotate, and the friction force is used to make the plate close to the baffle frame on the top of the base box 1. 3. Before this, it is necessary to adjust the position of the baffle frame 3 according to the cutting length. First, turn the handle 53, and then the handle 53 drives the worm 52 to rotate. The worm 52 drives the threaded rod 4 to rotate through the worm gear 51, and then the threaded rod 4 drives the baffle frame 3 to move outside the machine base box 1. Then, the position of the baffle frame 3 is adjusted according to the scale 6. Then, the servo motor 202 drives the cutting blade 203 to rotate, and the second electric push rod 204 drives the mounting frame 201 and the cutting blade 203 to move from back to front to cut the plate.
