[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: an automatic grinding device for a disc knife, comprising: a grinding table 1, a first moving seat 2, a first motor 3, a grinding wheel 4, a protective cover 5, a first threaded rod 6, a second moving seat 7, a sector wheel 8, a rack 9, a second motor 10, a knife to be ground 11, a second threaded rod 12, a connecting frame 13, a limiting rod 14, a gear 15, a slag leakage port 16, a guide groove 17 and a collection box 18;
[0028] When using this automatic grinding device for a disc knife, as Figure 1 Figure 2 and Figure 3As shown, remove the nut on the output shaft of the second motor 10, install the knife to be ground 11 on the output shaft of the second motor 10, and then bind the nut back. The knife to be ground 11 will be fixed on the output shaft of the second motor 10. Lift the limit rod 14 upward. The upper half of the cross-section of the shaft of the limit rod 14 is an octagon, and the lower half is an annular cross-section. After lifting, the limit rod 14 will break free from the restraint of the connecting frame 13, and the gear 15 on the lower side of the limit rod 14 is still meshed with the rack 9. Rotate the limit rod 14, and the limit rod 14 will drive the gear 15 to rotate together, and then drive the rack 9 to rotate together, so that the sector wheel 8 rotates around the connecting shaft of the second moving seat 7 and the sector wheel 8. At this time, the second motor 10 fixed on the upper side of the sector wheel 8 will rotate together with the sector wheel 8, and the angle between the knife to be ground 11 and the grinding wheel 4 changes from parallel to intersecting. Then put the limit rod 14 back into the connecting frame 13. At this time, the connecting frame 13 will restrain the limit rod 14, and then keep the sector wheel 8 in a fixed state. Then the edge of the knife to be ground 11 can be ground into the desired angle;
[0029] As Figure 1 , Figure 3 and Figure 5 shown, start the first motor 3 and the second motor 10. The first motor 3 will drive the grinding wheel 4 to rotate together, and the second motor 10 will drive the knife to be ground 11 to rotate together. A protective cover 5 is provided on the outside of the grinding wheel 4. The protective cover 5 is fixedly connected to the first motor 3, and the protective cover 5 will not rotate with the grinding wheel 4. The second threaded rod 12 is threadedly connected to the grinding table 1 and rotatably connected to the connecting block on the upper side of the second moving seat 7. Rotate the second threaded rod 12, and the second threaded rod 12 will move the second moving seat 7 backward on the upper side of the grinding table 1. When the rotating knife to be ground 11 contacts the rotating grinding wheel 4, the grinding wheel 4 will grind the upper side of the knife to be ground 11 until the left side of the inclined knife to be ground 11 is parallel to the side of the grinding wheel 4. Since the knife to be ground 11 is rotating, the entire side of the knife to be ground 11 will be ground into an inclined state. Then turn off the grinding wheel 4 and the knife to be ground 11, rotate the second threaded rod 12 in the reverse direction, and the second threaded rod 12 will move the second moving seat 7 backward, and then remove the knife to be ground 11, replace the other side, and then grind the knife to be ground 11 in the same way;
[0030] As Figure 1 , Figure 2 and Figure 5 shown, when the grinding wheel 4 and the knife to be ground 11 are grinding, the debris ground off will fall into the slag leakage port 16 and then into the guide groove 17. The guide groove 17 is inclined downward when viewed from the side. The debris falling into the guide groove 17 will slide into the collection box 18, which is convenient for cleaning;
[0031] As Figure 1As shown in the figure, when it is necessary to sharpen or blunt the knife 11 to be polished, it is necessary to adjust the distance between the grinding wheel 4 and the knife 11 to be polished. Rotate the first threaded rod 6. The first threaded rod 6 is threadedly connected to the grinding table 1, and the first threaded rod 6 is rotatably connected to the first moving seat 2. The first moving seat 2 is connected to the grinding table 1 by a card slot. Rotating the first moving seat 2 will cause the first moving seat 2 to move left and right on the grinding table 1, thereby driving the first motor 3 to move, and the distance between the grinding wheel 4 and the knife 11 to be polished can be adjusted, so that the blade of the knife 11 to be polished can be ground into the desired sharpness condition.
