DETAILED DESCRIPTION

[0021] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a disc blade mechanism of a longitudinal shearing and slitting machine, comprising: a mounting plate 1, a fixing plate 3 is symmetrically fixedly installed in the middle of the top of the mounting plate 1, a mounting seat 6 is symmetrically rotatably installed in the middle of the fixing plate 3, a rotating shaft 4 is fixedly installed inside the mounting seat 6 on the same side, a cutting knife 5, the cutting knife 5 is evenly distributed and installed on the outer periphery of the rotating shaft 4, and an adjusting mechanism 7 is arranged on the outer periphery of the cutting knife 5, and the adjusting mechanism 7 includes a bracket 705, the bracket 705 is symmetrically distributed and fixedly installed on the upper part of the outer periphery of the cutting knife 5, and a limit pin 706 is slidably installed in the middle of the bracket 705, and the limit pin 706 is slidably installed in the middle of the bracket 705. The outer circumference of the positioning pin 706 is sleeved with a spring 704, and the outer circumference of the rotating shaft 4 is opened with a plurality of evenly distributed limiting holes 702. By pulling the limiting pin 706, the limiting pin 706 can be disengaged from the limiting hole 702, and the spring 704 will be compressed. Then the cutting knife 5 can be moved as needed, and the relevant position of the cutting knife 5 can be adjusted. After the adjustment is completed, the limiting pin 706 is released, and the spring 704 will re-engage the limiting pin 706 in the limiting hole 702, thereby completing the limiting fixation of the cutting knife 5, thereby reducing the adjustment time and facilitating improving the processing efficiency of the product.

[0023] The outer circumference of the rotating shaft 4 is symmetrically provided with guide grooves 701, and a plurality of evenly distributed guide blocks 707 are slidably installed in the guide grooves 701. The guide blocks 707 are fixedly installed in pairs inside the cutting blade 5 on the same side. The guide blocks 707 are symmetrically provided with mounting grooves 709, and a plurality of evenly distributed ball bearings 708 are embedded and installed in the mounting grooves 709. The lower part of the outer circumference of the limit pin 706 is fixedly installed with a baffle plate 703, one end of the spring 704 is fixedly installed on the top of the baffle plate 703 on the same side, and the other end of the spring 704 is fixedly installed on the top of the bracket 705 on the same side. When the cutting blade 5 moves, the guide block 707 will move in the guide groove 701. Since the ball bearings 708 are installed on the guide block 707, at this time, the ball bearings 708 can convert the sliding friction between the guide block 707 and the guide groove 701 into rolling friction, thereby reducing the friction between the guide block 707 and the guide groove 701, thereby improving the smoothness of the movement of the cutting blade 5.

[0024] The driving mechanism 2 is arranged on the surface of the fixed plate 3 on one side. The driving mechanism 2 is used to drive the rotating shaft 4 to rotate. The driving mechanism 2 includes a motor mounting frame 202, which is fixedly mounted on the lower part of the fixed plate 3 on one side. A stepper motor 203 is fixedly mounted on the top of the motor mounting frame 202. A driving wheel 201 is fixedly mounted on the driving end of the stepper motor 203. The driving wheel 201 drives the driven wheel 204 to rotate through a synchronous belt 205. The driven wheel 204 is fixedly mounted on the end of the upper mounting seat 6 on one side, and the mounting seat on the other side 6 ends are fixedly installed with transmission gears 206 and the two transmission gears 206 are meshed with each other. By controlling the stepper motor 203, the stepper motor 203 can drive the driving wheel 201 to rotate. Since the driving wheel 201 is connected to the driven wheel 204 through the synchronous belt 205, the driven wheel 204 can drive the upper rotating shaft 4 to rotate, and under the cooperation of the transmission gear 206, the lower rotating shaft 4 can rotate in the opposite direction to the upper rotating shaft 4, and the cutting knife 5 can rotate synchronously with the rotating shaft 4 on the same side.

[0025] During actual use, the staff will fix the mounting plate 1, and then according to the cutting requirements, the staff can use the limit pin 706 in conjunction with the spring 704 and the limit hole 702 to adjust the position of the cutting knife 5. When the adjustment is completed, the staff can control the stepper motor 203. The stepper motor 203 cooperates with the driving wheel 201, the driven wheel 204, the synchronous belt 205 and the transmission gear 206 to realize the rotation of the cutting knife 5 on the two rotating shafts 4. At this time, the external auxiliary equipment can transfer the processing material to be cut into the cutting knife 5, so that the cutting can be completed.

[0026] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
