[0024] See also Figures 1 to 3 In the embodiment of the utility model, a cutting machine for facilitating replacement of blades comprises a base plate 1, a bracket 2 is fixedly mounted on the upper side of the base plate 1, a servo motor 3 is fixedly mounted on the right side of the bracket 2, a screw rod 4 is fixedly mounted on the output end of the servo motor 3, a screw block 5 is threadedly connected to the outer side of the screw rod 4, a manual telescopic rod 6 is fixedly mounted on the lower side of the screw block 5, a limit plate 7 is fixedly mounted on the lower end of the manual telescopic rod 6, a guide block 8 is fixedly mounted on the upper side of the screw block 5, a right angle bracket 9 is fixedly mounted on the right side of the bracket 2, a guide rod 10 is arranged on the lower side of the right angle bracket 9, an electric telescopic rod 11 is arranged on the right side of the bracket 2, a cutting motor 12 is fixedly mounted on the upper end of the electric telescopic rod 11, a main shaft rod 13 is fixedly mounted on the output end of the cutting motor 12, a positioning plate 14 is fixedly mounted on the outer side of the main shaft rod 13, a tooth 15 is fixedly mounted on the right side of the positioning plate 14, a blade 16 is arranged on the right side of the positioning plate 14, and a card slot 17 is opened inside the blade 16.

[0025] See also Figure 1-3 A motor mounting plate is fixedly installed at the bottom of the servo motor 3, and the position of the servo motor 3 is fixed by the motor mounting plate so that it can be in a specified position and maintain normal operation.

[0026] See also Figure 1-2 The manual telescopic rod 6 is composed of a sub-rod, a mother tube and a length adjustment knob. The sub-rod is slidably connected in the mother tube, and the length adjustment knob is threadedly connected in the mother tube, wherein one end of the length adjustment knob abuts against the sub-rod. The height of the limit plate 7 can be adjusted by the manual telescopic rod 6 to facilitate keeping it at the same height as the main shaft rod 13.

[0027] See also Figure 1-2 The guide block 8 is slidably connected to the guide rod 10. By using the guide block 8 and the guide rod 10 in combination, the movement trajectory of the screw block 5 can be limited, so that the screw block 5 only moves horizontally on the screw rod 4 and will not rotate synchronously with the screw rod 4, thereby ensuring that the movement of the screw block 5 is more stable.

[0028] See also Figure 1-2 The guide rod 10 is fixedly installed between the bracket 2 and the right-angle bracket 9, and the position of the guide rod 10 is fixed by the bracket 2 and the right-angle bracket 9.

[0029] See also Figure 1-3 The teeth 15 and the slot 17 fit together, and the positioning of the blade 16 can be preliminarily completed by using the teeth 15 and the slot 17 in cooperation.

[0030] The working principle of the utility model is as follows: when the blade 16 of the cutting machine needs to be replaced, the servo motor 3 is directly started, the servo motor 3 drives the screw rod 4 to rotate, the screw rod 4 drives the screw block 5 to move, and at the same time, the guide block 8 will slide synchronously on the guide rod 10, the guide block 8 and the guide rod 10 are used together to limit the movement trajectory of the screw block 5, so that the screw block 5 only moves horizontally on the screw rod 4, and will not rotate synchronously with the screw 4, so as to ensure that the movement of the screw block 5 is more stable, the screw block 5 will drive the manual telescopic rod 6 to move, and the manual telescopic rod 6 can be manually retracted. The rod 6 drives the limit plate 7 to move. When the limit plate 7 is separated from the main shaft rod 13, the cutting wheel 16 can be removed for replacement. The blade of the cutting machine can be disassembled, which is convenient for daily replacement. When a new blade 16 needs to be installed, the blade is directly passed through the main shaft rod 13, so that the groove 17 inside the blade 16 is connected to the teeth 15 on the positioning plate 14, and the initial limit of the blade 16 is completed. Then the servo motor 3 is started. According to the same principle, the limit plate 7 is returned to the main shaft rod 13 and fits one side of the blade 16 to complete the installation of the new blade 16.

[0031] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
