[0017] (1) The cutting machine, when the medical dialysis paper is needed to be installed, the medical dialysis paper is placed on the bearing structure, the bearing structure can play a role in bearing and positioning the medical dialysis paper, so as to avoid the need to hold the dialysis paper by hand during installation, improve the convenience of installation, then the rod is inserted through the winding roller, and the winding roller is fixed with the rod through the fixing structure, and the rod is fixed through the clamping structure and one of the connecting sleeves, and the bearing structure can move away from the dialysis paper during the movement of the clamping structure, so that there is a gap between the dialysis paper and the bearing structure, which is convenient for the rotation of the dialysis paper roll, that is, when the medical dialysis paper is needed to be installed, the medical dialysis paper is placed in the placing groove, and when the medical dialysis paper is placed in the placing groove, the axis of the winding roller in the middle of the dialysis paper roll is exactly on the same straight line as the axes of the two connecting sleeves, and the end of the first clamping block is located in the groove, at this time, the rod can be inserted through the connecting sleeve and the winding roller, when the end of the rod is in contact with the rack, the first screw is rotated by the rotating rod, the first screw is threadedly driven to slide the abutting block, and the first screw drives the sliding block to slide, the sliding of the sliding block will abut the first clamping block to move, the first clamping block abuts the top block to move, and the first return spring is contracted, with the movement of the first clamping block, the first clamping block is clamped with the connecting sleeve, so as to avoid the relative movement between the rod and the connecting sleeve, improve the stability, and the stop block will move during the movement of the sliding block, the stop block will abut the sliding rod to move, since the second clamping block is clamped with the first clamping groove, the bearing plate will not move at this time, the sliding rod will abut the second clamping block to move away from the first clamping groove, the third return spring is contracted, and the second return spring is contracted, when the second clamping block moves to the first clamping groove, since the elastic force of the second return spring is greater than that of the fourth return spring, the second return spring will be elongated to reset the bearing plate, the fourth return spring is elongated, so that the bearing plate and the dialysis paper maintain a certain distance, so as to avoid the bearing plate resisting the dialysis paper during the rotation of the dialysis paper, and facilitate the rotation of the dialysis paper, with the rotation of the first screw, the abutting block will slide until it is tightly abutted between the two fixed blocks, at this time, the two fixed blocks are tightly abutted with the winding roller, so that the winding roller and the rod are fixed, effectively avoiding the movement of the dialysis paper on the rod during the rotation, improving the stability, and then during the installation of the dialysis paper roll, the heavy dialysis paper roll is placed in the placing groove, which can avoid the need for multiple installers to hold the dialysis paper roll by hand during installation, improve the convenience of installation, and the dialysis paper roll is placed in the placing groove, which can play a role in positioning the dialysis paper roll, so as to ensure that the position of the dialysis paper roll remains unchanged after each installation, and ensure the quality of the cut product.

[0018] (2) The cutting machine can change the position of the cutting structure through the lifting structure, so that when cutting is not needed, the cutting structure can be completely inside the protection structure through the lifting structure, so as to shield and protect the cutting structure, thereby avoiding damage to the cutting structure due to impact, reducing dust accumulation on the cutting structure, and ensuring the cleanliness of the cutting structure. That is, when the dialysis paper is not cut, the hand dial is rotated, one of the second lead screws is driven to rotate by the hand dial, one of the synchronous wheels is driven to rotate by the second lead screw, the other synchronous wheel is driven to rotate by the synchronous belt, and the other second lead screw is driven to rotate by the synchronous wheel. The rotation of the hand dial drives the two second lead screws to rotate simultaneously, and the rotation of the second lead screw drives the lifting block to move, and the movement of the lifting block drives the cutting knife to move, so that the cutting knife is located inside the baffle, thereby shielding and protecting the cutting knife through the baffle, effectively avoiding damage to the cutting knife due to impact, reducing dust accumulation on the cutting knife, and ensuring the cleanliness of the cutting knife surface.

[0019] (3) The cutting machine can cut medical dialysis paper through the cutting structure, and when the cutting structure needs to be replaced and repaired, only the protection structure needs to be rotated to prevent the protection structure from resisting the cutting structure. At this time, the cutting structure can be removed and washed for repair and replacement. That is, during the cutting process, the output shaft of the motor drives the two connecting rods and the connecting shaft to rotate, the connecting shaft drives the cutting knife to rotate, and the cutting knife is in contact with the dialysis paper and rotates to cut the dialysis paper. When the cutting knife needs to be repaired and replaced, the push block is pushed, the third clamping block moves away from the second clamping groove, and when the third clamping block is not engaged with one of the second clamping grooves, the baffle is rotated by 90 degrees. At this time, the third clamping block is engaged with the other second clamping groove under the action of the fifth return spring, so that the baffle does not resist the cutting knife, and then the two threaded sleeves are rotated to resist the connecting shaft. At this time, the connecting shaft can be removed from the two connecting rods. After removal, the wrench is rotated, the knob is rotated to drive the pressing block away from the connecting shaft, and when the four pressing blocks are not in contact with the connecting shaft, the cutting knife can be removed from the connecting shaft. After removal, the cutting knife can be replaced and repaired, thereby improving the efficiency of cutting knife repair and maintenance. BRIEF DESCRIPTION OF DRAWINGS

With the movement of the first clamping block 503, the first clamping block 503 will be clamped with the connecting sleeve 3, so as to avoid the relative movement between the plug rod 2 and the connecting sleeve 3, improve the stability, and drive the stop block 601 to move in the process of the sliding block 501 movement. The stop block 601 will resist the movement of the sliding rod 602. Since the second clamping block 605 is clamped with the first clamping groove 607, the bearing plate 608 will not move at this time. The sliding rod 602 will resist the movement of the second clamping block 605 away from the first clamping groove 607, the third reset spring 606 is contracted, and the second reset spring 604 is contracted. When the second clamping block 605 moves to the first clamping groove 607, the second reset spring 604 will be stretched to reset the bearing plate 608 to move, and the fourth reset spring 609 is stretched, so that the bearing plate 608 and the dialysis paper maintain a certain distance, thereby avoiding the bearing plate 608 resisting the dialysis paper when the dialysis paper rotates, facilitating the rotation of the dialysis paper.

Further, during the installation of the dialysis paper roll, the heavier dialysis paper roll is placed in the placing groove 610, which can avoid the need for multiple installers to hold the dialysis paper roll by hand during installation, improving the convenience of installation. Moreover, placing the dialysis paper roll in the placing groove 610 can position the dialysis paper roll, thereby ensuring that the position of the dialysis paper roll remains unchanged after each installation, ensuring the quality of the cut product.

[0037] Specifically, the protective structure 7 includes a protective cover 701, which is fixedly connected to the frame 1. A baffle 702 is rotatably connected to the protective cover 701. A third locking block 704 is slidably connected to the protective cover 701. A fifth return spring 706 abuts against the third locking block 704 and the protective cover 701. The baffle 702 has two second slots 705, and the third locking block 704 engages with one of the second slots 705. A push block 703 is fixedly connected to the third locking block 704. One end of the cross-section of the third locking block 704 is trapezoidal.

The lifting block 905 is slidably connected to a protective cover 701. A soft curtain 906 is fixedly connected between the lifting block 905 and the protective cover 701. That is, when it is not necessary to cut the dialysis paper, rotating the handwheel 901 will drive one of the second lead screws 902 to rotate. The rotation of the second lead screw 902 will drive one of the synchronous pulleys 903 to rotate. The rotation of the timing belt 904 drives another timing pulley 903 to rotate, which in turn drives another second lead screw 902 to rotate. By rotating the handwheel 901, both second lead screws 902 rotate simultaneously. The rotation of the second lead screws 902 drives the lifting block 905 to move, which in turn drives the cutting blade 805 to move. This places the cutting blade 805 inside the baffle 702, which protects the cutting blade 805 from impact and reduces dust accumulation on it, keeping its surface clean. The soft curtain 906 further reduces dust entering the protective cover 701, ensuring the cleanliness of the interior of the protective cover 701.

[0039] The application is used when the medical dialysis paper roll needs to be installed. The medical dialysis paper is placed in the placing groove 610. When the medical dialysis paper is placed in the placing groove 610, the axis of the winding roller 10 in the middle of the dialysis paper roll is in the same straight line with the axes of the two connecting sleeves 3, and the end of the first clamping block 503 is in the groove 502. At this time, the insertion rod 2 can pass through the connecting sleeve 3 and the winding roller 10. When the end of the insertion rod 2 is in contact with the rack 1, the first screw rod 402 is rotated through the rotating rod 401. The first screw rod 402 threadedly drives the abutting block 403 to slide, and at the same time, the first screw rod 402 drives the sliding block 501 to slide. The sliding of the sliding block 501 will abut against the movement of the first clamping block 503. The first clamping block 503 abuts against the movement of the top block 504. The first reset spring 505 is contracted. With the movement of the first clamping block 503, the first clamping block 503 will be clamped with the connecting sleeve 3, so as to avoid the relative movement between the insertion rod 2 and the connecting sleeve 3, improve the stability, and drive the stop block 601 to move in the process of the movement of the sliding block 501. The stop block 601 will abut against the movement of the sliding rod 602. Since the second clamping block 605 is clamped with the first clamping groove 607 at the beginning, the bearing plate 608 will not move at this time. The sliding rod 602 will abut against the movement of the second clamping block 605 away from the first clamping groove 607. The third reset spring 606 is contracted, and the second reset spring 604 is contracted. When the second clamping block 605 moves to be not clamped with the first clamping groove 607, since the elastic force of the second reset spring 604 is greater than that of the fourth reset spring 609, the second reset spring 604 will be elongated to drive the bearing plate 608 to move, and the fourth reset spring 609 is elongated, so that the bearing plate 608 keeps a certain distance from the dialysis paper, thereby avoiding the bearing plate 608 from resisting the dialysis paper when the dialysis paper rotates, facilitating the rotation of the dialysis paper. With the rotation of the first screw rod 402, the abutting block 403 will slide until it is tightly abutted with the two fixed blocks 404. At this time, the two fixed blocks 404 are tightly abutted with the winding roller 10, so that the winding roller 10 is fixed with the insertion rod 2, effectively avoiding the movement of the dialysis paper on the insertion rod 2 in the process of rotation, improving the stability. Further, in the process of installing the dialysis paper roll, the heavy dialysis paper roll is placed in the placing groove 610, which can avoid the need for multiple installers to hold the dialysis paper roll by hand during installation, improving the convenience of installation. Moreover, the dialysis paper roll is placed in the placing groove 610, which can play a positioning role on the dialysis paper roll, thereby ensuring that the position of the dialysis paper roll remains unchanged after each installation, ensuring the quality of the product after slitting,
