The driving wheel 2 is fixed between two circular bearings 22, and there are two supporting points located at two ends, while the traditional cantilever is fixed with only one supporting point. The two support points increase the rigidity of the driving shaft 21, compared with one support point, the driving shaft 21 of the two support point forming mechanisms has much smaller strain, and the driving wheel 2 is much more stable at high-speed rotation speed.
As shown in fig. 1 and 5: the upper ends of the main bottom plate 12 and the auxiliary bottom plate 13 are respectively provided with a slide block bearing 32. The driven shaft 31 and the driven wheel 3 are supported by these two slider bearings 32 and are freely rotatable in the axial direction.

As shown in fig. 5 and 6: the output shaft of the adjustable lifter 81 can extend or retract, and has a good self-locking function. The height adjustment plate 83 is slidable up and down by the limit action of the height adjustment rail 84. When the output shaft of the lifter 81 extends out, the height adjusting seat 82 moves upwards, the height adjusting seat 82 pushes the two height adjusting plates 83 to slide upwards, and the height adjusting plates 83 drive the driven wheel 3 to move upwards, so that the function of tensioning the band saw is realized. When the output shaft of the lifter 81 retracts, the height adjusting seat 82, the height adjusting plate 83 and the driven wheel 3 move downwards, and the function of loosening the band saw 4 is realized. When in normal use, the band saw 4 is in a tensioning state; when the band saw is replaced, the band saw 4 is in a relaxed state.

Production or processing errors can cause the axes of the driving wheel 2 and the driven wheel 3 to be unparallel, the heights of the two sliding block bearings 32 can be adjusted, and the axes of the driving wheel 2 and the driven wheel 3 can be parallel by adjusting the angle of the axes of the driven wheel 3 by using the height difference. Only when the axes of the driving wheel 2 and the driven wheel 3 are parallel, the driving wheel 2, the driven wheel 3 and the transmission mechanism formed by the band saw 4 can run stably, and the stress of the band saw 4 can be balanced.
As shown in fig. 2 and 8, the middle section of the band saw 4 moves linearly in the direction S. When the cutting platform Q moves linearly back and forth along the direction Y relative to the band saw 4, the band saw 4 moving at a high speed can cut the long piece of paper L into the square pieces of paper D. The thickness of the reversing plate 10 is thicker than that of the band saw, when cutting is completed and the cutting platform Q returns to the original position in the opposite direction, the reversing plate 10 pushes away a larger gap between the long-strip paper L and the square paper D, so that the back of the band saw 4 is not contacted with the long-strip paper L and the square paper D, secondary cutting is avoided, and the flatness of a paper cutting surface is ensured.
As shown in fig. 8: the diamonds 9 arranged on the left side and the right side of the band saw 4 have a limiting effect on the band saw, so that the middle section of the band saw 4 moves more stably, and the flatness of a paper cutting surface is ensured.
As shown in fig. 6 and 7: when the sharpening cylinder 72 extends or retracts respectively, the grinding wheels 71 are in contact with or separate from the band saw 4, and when the two grinding wheels contact the band saw 4 at a certain angle, the blade surface of the band saw 4 is ground at a certain angle, so that the sharpening function is realized.
As shown in fig. 2 and 6, the position of the motor 5 on the rack 65 can be adjusted by adjusting the nut, and the center distance between the large pulley 61 and the small pulley 62 is changed to realize the function of adjusting the tension of the belt 63.
