[0037] Working principle: When working, first observe the condition of the slices. Generally, there are two conditions for slicing: the first is that the middle is relatively flat and both ends need to be leveled; the second is that one end is relatively flat and the other end needs to be leveled;

[0038] When the middle part is relatively flat and the two ends need to be leveled, the horizontal frame 1 is moved to the top of the slice by hoisting the mobile device, and then the horizontal frame 1 is moved downward, so that the second pressing roller 604 and the two first pressing rollers 601 are pressed downward to the middle of the slice, and then the two first motors 5 are turned on, so that after the screw 4 rotates, the two first pressing rollers 601 roll away from each other, and the two ends of the slice are leveled at the same time;

[0039] When one end is relatively flat and the other end needs to be leveled, the horizontal frame 1 is powered on to lift the moving device and move it above the slice, and the second pressing roller 604 and the two first pressing rollers 601 are all moved above one end of the slice, and then the horizontal frame 1 moves downward, so that the second pressing roller 604 and the two first pressing rollers 601 are all pressed on the flat end of the slice, at this time the clamping block 804 is clamped with the clamping groove 705, after turning on the second motor 815, it drives the rotating cylinder 803 to rotate, and then drives the rotating block 702 to rotate, so that the push rod 708 faces the side that needs to be leveled, and then the first electromagnet 711 is energized to generate a repulsive force on the first magnetic block 710, so that the push rod 708 moves outward and is inserted into the internal groove 7126, and the first electromagnet 711 is powered on to generate a repulsive force on the first magnetic block 710, so that the push rod 708 moves outward and is inserted into the internal groove 7126, and the first electromagnet 711 is powered on to generate a repulsive force on the first magnetic block 710, so that the push rod 708 moves outward and is inserted into the internal groove 7126, and the second electromagnet 711 is powered on to generate a repulsive force on the first electromagnet 711, and ... second electromagnet 711 is powered on to generate a repulsive force on the first electromagnet 711, and the second electromagnet 711 is powered on to generate a repulsive force on the first electromagnet 711, and the second electromagnet 7 The second push plate 71211 generates pressure, and because the end of the card block 7128 contacts the inner wall of the first rod groove 7121 at this time, the insertion rod 7122 and the second push plate 71211 move outward synchronously and are inserted into the slot 607 on the sliding block 603. When the card block 7128 corresponds to the card groove 608, the second push plate 71211 moves relative to the insertion rod 7122, and pushes the card block 7128 to move outward and snap into the card groove 608 through the connecting rod 71210, so that the top block 606 and the sliding block 603 are snapped and fixed. At this time, the first motor 5 on one side is turned on, so that the first pressure roller 601 and the second pressure roller 604 on one side move synchronously, and the end of the slice that needs to be flattened is flattened twice, thereby improving the flattening effect;

[0040] When the first pressing roller 601 and the second pressing roller 604 on one side move, the second electromagnet 810 is energized to generate attraction to the second magnetic block 809 , thereby driving the rotating cylinder 803 to move upward, so that the clamping block 804 enters the bottom groove 802 .
