[0002] After production, superabsorbent polymer (SAP) needs to be slit and crushed into particles of suitable size for use in the manufacture of products in various fields. In existing technology, the SAP needs to be cut by a slitting machine before crushing to ensure it can smoothly enter the crusher's feed inlet for subsequent crushing.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-4 In this embodiment of the present invention, a slitting machine for superabsorbent resin includes a rotating shaft 1, a first end plate 3, and a second end plate 4. The first end plate 3 and the second end plate 4 are distributed directly below both ends of the rotating shaft 1. A slitting blade 2 is installed on the outer periphery of the rotating shaft 1 through a threaded set screw. A guide shaft 6 is fixedly installed between the first end plate 3 and the second end plate 4. A hollow shaft 5 is fixedly installed between the first end plate 3 and the second end plate 4. The hollow shaft 5 is located at the front end of the guide shaft 6. A sliding seat 7 is slidably installed on the outer wall of the hollow shaft 5 and the guide shaft 6. A moving mechanism is installed at one end of the first end plate 3, extending into the hollow shaft 5 and extending to the outer wall of the hollow shaft 5. The moving mechanism is used to drive the rotating mechanism to move synchronously. An infrared sensor 9 is fixedly installed at the center of the second end plate 4. A reflector 10 aligned with the infrared sensor 9 is installed at the center of the sliding seat 7.
[0018] In this embodiment: When cutting the hydrophilic resin, the motor connected to the rotating shaft 1 is started. The motor drives multiple cutting blades 2 to rotate through the rotating shaft 1, thus cutting the sheet-like hydrophilic resin and facilitating crushing during the granulation process. If it is necessary to adjust the spacing between multiple adjacent cutting blades 2 according to the feed inlet of the crusher, the set screws fixing the cutting blades 2 are first loosened. At this time, the cutting blades 2 can slide outside the rotating shaft 1. Then, the spacing value between adjacent cutting blades is set through the program, and then the moving mechanism is started. The movement of the moving mechanism drives the reflector head 10 through the sliding seat 7. Synchronous movement occurs when infrared sensor 9 emits an infrared signal, which is reflected back by the mirror at one end of reflector head 10 until the distance between reflector head 10 and infrared sensor 9 meets the set value. At this time, infrared sensor 9 sends an electrical signal to controller, which can then control the servo moving mechanism to stop running. At this time, sliding seat 7 remains in its current position. Then, a thrust is applied to the rotating mechanism, and it contacts the outer wall of rotating shaft 1. This pushes the slitting blade 2, which is closest to the rotating mechanism, to move and contact the rotating mechanism. Then, the set screw on the slitting blade 2 is rotated to fix the slitting blade 2 in its current position.
[0019] Then, by analogy, multiple slitting blades 2 can be fixed at equal intervals. In this way, multiple slitting blades 2 can be fixed at equal intervals quickly without the need for individual measurement and calibration, thus improving the adjustment efficiency of the slitting blades 2.
[0020] It should be noted that: an infrared sensor emits a beam of infrared light, which shines on a target object. The target object reflects some of the infrared light back, and the receiver receives this reflected infrared light. Time difference calculation: by measuring the time difference between the emission and reception of infrared light, and combining it with the known infrared propagation speed, the distance between the object and the sensor can be calculated.
[0021] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The moving mechanism includes a servo motor 8 fixedly installed on the outside of the first end plate 3. A screw 12 is rotatably installed between the first end plate 3 and the second end plate 4. The screw 12 is located in the inner cavity of the hollow shaft 5. The output end of the servo motor 8 is coaxially and fixedly connected to one end of the screw 12. A threaded sleeve 13 is threadedly connected to the outer wall of the screw 12. A fixing block 14, which is fixedly connected to the inner circumference of the sliding seat 7, is fixedly installed at the bottom outer periphery of the threaded sleeve 13. A strip groove 11 for the fixing block 14 to slide is opened at the bottom outer periphery of the hollow shaft 5. An infrared sensor 9 is electrically connected to the servo motor 8 through a controller.
[0022] In this embodiment: by starting the servo motor 8, the servo motor 8 drives the pre-connected screw 12 to rotate. When the screw 12 rotates, the screw sleeve 13 slides along the inner wall of the hollow shaft 5 under its internal thread. The hollow shaft 5 drives the sliding seat 7 to slide through the fixed block 14. At this time, the sliding seat 7 can drive the reflector head 10 to move synchronously. At the same time, the moving sliding seat 7 can drive the rotating mechanism to move synchronously. When the distance between the reflector head 10 and the infrared emitter 9 meets the set distance, the servo motor 8 stops running.
[0023] Please refer to this carefully. Figure 3 and Figure 4 The rotating mechanism includes a connecting ear 15 fixedly installed on the outer periphery of one end of the sliding seat 7. A rotating arm 16 is rotatably installed on the inner side of the connecting ear 15. An arc-shaped groove 17 is provided on the connecting ear 15. A movable column 18 fixedly connected to the outer wall of the rotating arm 16 is movably connected inside the arc-shaped groove 17. A sliding groove 19 is provided on the inner wall of the rotating arm 16 along its length. A sliding column 21 is slidably installed on the inner wall of the sliding groove 19. Telescopic arms 20 are rotatably installed at both ends of the sliding column 21. A sleeve 22 rotatably connected to the outer wall of the telescopic arm 20 is slidably installed on the outer wall of the connecting ear 15. A spring 23 is fixedly installed between the bottom end of the inner wall of the sleeve 22 and the lower part of the outer wall of the telescopic arm 20.
[0024] In this embodiment: After the sliding seat 7 drives the rotating arm 16 to move to the preset position, the rotating arm 16 can be pushed to rotate in the direction of the rotating shaft 1. At this time, the rotating arm 16 drives the sliding groove 19 inside to rotate synchronously. The rotating sliding groove 19 squeezes the sliding column 21, and the squeezing force is transmitted to the telescopic arm 20. The telescopic arm 20 slides towards the inner wall of the sleeve 22. At this time, the spring 23 is compressed until the rotating arm 16 contacts the outer periphery of the rotating shaft 1. At this time, the slitting blade 2 close to the rotating arm 16 can be pushed to slide axially and abut against the rotating arm 16, thus rotating. The set screw on the slitting blade 2 fixes the slitting blade 2. After fixing, the limiting force applied to the rotating arm 16 is removed. At this time, the spring 23 pushes the telescopic arm 20 to the limit. The telescopic arm 20 applies a pushing force to the sliding groove 19 through the sliding column 21. Under the pushing force, the rotating arm 16 can rotate and reset. At the same time, during the reset process, the rotating arm 16 drives the moving column 18 to rotate in the arc groove 17. When the rotating arm 16 is in the vertical state, the moving column 18 abuts against the upper end of the arc groove 17. At this time, the rotating arm 16 cannot continue to rotate, so that the rotating arm 16 is kept in the current position.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
