When the sawing is completed, a person manually operates the sawing handle 32 to move the sawing handle 32 upward, the rotating frame 5 rotates in the opposite direction to drive the saw disc 31 to move upward to the initial position (the saw disc 31 is located at the uppermost position).
[0025] The sawing device of the embodiment is used to drive the saw disc 31 to move downward by operating the sawing handle 32, and then the saw disc 31 rotates by itself to saw the rotating material roll to be sawed, and the person operates the sawing handle 32 to be far away from the saw disc 31 as much as possible, thereby effectively reducing the possibility of being injured by the saw disc 31 or splashed material residue. The material roll to be sawed rotates to complete the sawing, thereby improving the sawing efficiency.
[0026] The motorized slide 4 of the embodiment can drive the sawing assembly 3 on it to slide leftward and rightward. The sawing device of the embodiment can adjust the position of the sawing assembly 3 according to the sawing length requirement of the material roll, thereby cutting out products with different lengths to meet the user's requirement, and the application range is wide.
