In this embodiment, the second trigger lever 34 sequentially triggers the two second inductive sensors 33, and the rotation direction of the rotating disk 14 can be determined by the phase difference between the two second inductive sensors 33; therefore, when the operator rotates the rotary disk 14 back and forth in a small range, it can be judged that the trimming operation is being performed, and the feed controller can control the rotation angle of the lead screw 5, that is, the feed amount in trimming, according to the requirements of the trimming. The feed amount during trimming is generally larger than the feed amount during slicing. The feeding controller judges whether the sheet is being sliced or trimmed by signals transmitted from different second induction sensors 33, and controls the motor 6 to rotate at different angles according to different operations.

The second sensing sensor 33 is an infrared correlation sensor, and when the second trigger bar 34 is matched with the second sensing sensor 33, the light emitted by the infrared correlation sensor is shielded, so that the corresponding second sensing sensor 33 is triggered. In other embodiments, the second inductive sensor 33 can be a hall sensor, and when the second trigger bar 34 has a magnet, the magnet triggers the corresponding second inductive sensor 33 when the second trigger bar 34 cooperates with the second inductive sensor 33.

The implementation principle of the long-life high-precision feeding mechanism for the slicing machine is as follows: starting the motor 6, driving the screw rod 5 to rotate by the motor 6, driving the moving seat 2 to reciprocate along the X-axis direction by the rotating screw rod 5 so as to control the feeding amount of the chuck mounting seat 3, thereby adjusting the slice thickness of the biological tissue wax block; the disc body 18 is shaken, and the rotary disc body 18 controls the lifting of the chuck mounting seat 3 through the rotating shaft 13, so that the biological tissue wax block is sliced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
