[0002] When pathological tissue is sliced, it is necessary to fix the embedding box and then perform wax trimming (cut out the area to be sliced) and slicing (slice the area to be sliced) on the surface of the wax block. At present, the commonly used method is a pathological tissue slicing machine refrigeration device disclosed in the utility model patent with publication number CN211262901 U, which completes the relative movement between the wax block and the knife by manually shaking the wax block up and down. The applicant found that it is not easy to control the slicing speed by hand-cranking, and it is easy to cause the slice to be stuck due to the hand-cranking. Based on this, when conducting research on automatic slicing equipment, a power mechanism was used to drive the wax block and the knife to move relative to each other for wax trimming and slicing. In this process, how to ensure the stability of the quality of wax cutting is a key link. Summary of the invention

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0021] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0024] In the present invention, Figures 1 to 2As shown, a driving mechanism capable of stably cutting wax is provided, comprising a frame 1, a mounting frame 2 slidably mounted on the frame 1 in a vertical direction, the mounting frame 2 being rotatably connected to a connecting rod 3, the connecting rod 3 being connected to a laterally extending driving rod 4, the driving mechanism further comprising a driving disk 5, a first driving member 6 driving the driving disk 5 to rotate, the driving disk 5 being provided with a driving groove 7 extending radially thereof, the driving rod 4 passing through the driving groove 7; the driving mechanism further comprising a rotating shaft 8 coaxially arranged with the driving disk 5, and an adjusting assembly mounted on the rotating shaft 8, the adjusting assembly comprising a connecting portion capable of being connected to the driving rod 4, and the adjusting assembly being capable of driving the driving rod 4 to move radially along the driving disk 5.

[0025] When the drive mechanism of the present invention is slicing the wax block, the first drive member 6 drives the drive disk 5 to rotate. When the drive disk 5 rotates, the drive slot 7 drives the drive rod 4 to rotate together. The drive rod 4 then drives the mounting frame 2 to move up and down, so that the wax knife 21 or the embedding box fixed structure driven by the mounting frame 2 moves up and down to complete the wax trimming and slicing between the wax knife 21 and the wax block. When the relative stroke of the wax block and the wax knife 21 needs to be adjusted, the drive rod 4 can be driven by the adjustment component to move along the radial direction of the drive disk 5, so that the upper limit position and the lower limit position of the mounting frame 2 can be adjusted, and then the stroke of the mounting frame 2 can be conveniently adjusted.

[0026] The driving mechanism of the present invention is as follows Figure 2 As described, when the mounting frame 2 is located at the upper limit position or the lower limit position (at this time, the edge of the wax knife 21 is located at the edge of the wax block), the wax knife 21 gradually starts to cut the wax block. The first driving member 6 can realize the process of gradually accelerating the slicing speed of the wax knife 21 from a slow speed and then decelerating to a slow speed while maintaining a uniform rotation state. When the wax knife 21 starts to cut the wax, it can cut in at a low speed to reduce the impact on the wax block. In the process of gradual separation of the wax knife 21 and the wax block, the damage to the cut surface and the slice can be reduced by separating at a low speed. The wax cutting process can also have an acceleration stage to increase the wax cutting speed, thereby making it easier for the present invention to control the quality of wax cutting.

[0027] The present invention drives the mounting frame 2 to move back and forth up and down by rotating the driving disk 5, so that the first driving member 6 can rotate unidirectionally at a uniform speed to achieve the relative movement drive of the wax knife 21 and the wax block. Compared with the method of driving the wax knife 21 or the wax block by means of an electric telescopic rod, a screw moving mechanism, a gear rack moving mechanism, etc., the first driving member 6 of the present application does not need to frequently stop to adjust the driving direction during the wax cutting process, so that the first driving member 6 of the present application has a more stable working environment.

[0028] It should be noted that the improvement of the present invention lies in a driving mechanism for cutting wax from a wax block. In the illustrated embodiment, the mounting frame 2 is provided with a structure for fixing the wax block, and the wax knife 21 is fixed on the lower side of the mounting frame 2.

[0031] As shown in the figure, the driving part 11 is configured as an electric push rod, which pushes the connecting part to move linearly, thereby driving the connecting sleeve 9 to move linearly on the rotating shaft 8, and further driving the driving rod 4 to move radially along the driving disk 5. By installing the driving part 11 on the frame 1, the driving part 11 can be conveniently arranged.

[0032] In a preferred embodiment, for the structure of the present invention, more specifically, the connecting sleeve 9 is formed with an annular groove 13, and the connecting portion includes a connecting plate 1201 extending into the annular groove.

As shown in the figure, the mounting frame is provided with connecting columns, and the connecting belts are connected to the connecting columns.
