Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Referring to Figure 1-2 , an embodiment provided by the present invention: a slitting machine with an adjustment structure, including a base 1, a driving motor 2 is fixedly connected to the left side of the top of the base 1, the right end of the driving motor 2 is connected to a driving shaft 16 through a control component, and the control component is used to control the rotation speed of the driving shaft 16.

Two first fixing blocks 10 are fixedly connected to the right side of the top of the base 1. A guiding roller 9 is rotatably connected to the opposite ends of the first fixing blocks 10. A feeding roller 11 is rotatably connected to the inner wall of the first fixing block 10. The left side of the outer wall of the feeding roller 11 is connected to the driving shaft 16 through a transmission component. The transmission component is used to transmit the power of the driving shaft 16 to the feeding roller 11 to drive the feeding roller 11 to rotate. The transmission component includes a first pulley 8 fixedly connected to the left side of the outer wall of the feeding roller 11. The first pulley 8 and the second pulley 15 are connected by the inner side of the belt. Two second fixing blocks 12 are fixedly connected to the right side of the top of the base 1. Connecting rollers 14 are rotatably connected to the inner walls of the second fixing blocks 12. The right end of the driving shaft 16 is fixedly connected to the left end of the left connecting roller 14;

[0027] Specifically, start the driving motor 2 to drive the connecting shaft 4 to rotate. The rotation speed of the first transmission shaft 3 can be adjusted by the speed regulating box 5. Then, the kinetic energy is transmitted to the driving shaft 16 through the gear splitting box 7 by the second transmission shaft 6, so that the driving shaft 16 rotates to drive the connecting roller 14 to rotate, causing the slitting roller 13 to start cutting the steel plate. When the driving shaft 16 rotates, the feeding roller 11 can be synchronously driven to rotate under the cooperation of the second pulley 15, the first pulley 8 and the belt, feeding the entire device, so that feeding and slitting are synchronized under the drive of the same drive source.

[0028] Referring to Figures 3-5, a bidirectional threaded rod 17 is rotatably connected to the inner wall of the right connecting roller 14. The opposite ends of the connecting roller 14 are fixedly connected with longitudinal cutting rollers 13.

The inner walls of the knife seats 25 are slidably connected to the outer wall of the longitudinal cutting roller 13;

[0029] Specifically, during the slitting process, if there are different size requirements, the driving motor 2 can be stopped first. The worker manually rotates the twisting rod 18 to make the bidirectional threaded rod 17 rotate, prompting the two sliders 21 on the bidirectional threaded rod 17 to move towards or away from each other, so that the rotating blocks 24 rotate on the rotating rods 23, expand or contract to drive the connecting rods 22 to slide in the chutes 19, so as to change the distance between the ring-shaped blades 20 to control the size of the steel plate after slitting. Then the driving motor 2 can be restarted. When the ring-shaped blade 20 needs to be replaced, the bolts on the fixed ring 26 can be removed to take the fixed ring 26 off the knife seat 25 for replacing and maintaining the ring-shaped blade 20.

[0030] Working principle: Start the driving motor 2 to drive the connecting shaft 4 to rotate. The speed of the first transmission shaft 3 can be adjusted by the speed regulating box 5. Then the kinetic energy is transmitted from the second transmission shaft 6 to the driving shaft 16 through the gear splitting box 7, so that the driving shaft 16 rotates to drive the connecting roller 14 to rotate, and the longitudinal cutting roller 13 starts to slit the steel plate. When the driving shaft 16 rotates, the feeding roller 11 can be synchronously driven to rotate under the cooperation of the second belt pulley 15, the first belt pulley 8 and the belt to feed the whole device. The feeding and slitting are carried out synchronously under the drive of the same driving source. During the slitting process, if there are different size requirements, the driving motor 2 can be stopped first. The worker manually rotates the twisting rod 18 to make the bidirectional threaded rod 17 rotate, prompting the two sliders 21 on the bidirectional threaded rod 17 to move towards or away from each other, so that the rotating blocks 24 rotate on the rotating rods 23, expand or contract to drive the connecting rods 22 to slide in the chutes 19, so as to change the distance between the ring-shaped blades 20 to control the size of the steel plate after slitting. Then the driving motor 2 can be restarted. When the ring-shaped blade 20 needs to be replaced, the bolts on the fixed ring 26 can be removed to take the fixed ring 26 off the knife seat 25 for replacing and maintaining the ring-shaped blade 20.
