[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please refer to Figures 1, 2, and 3. This embodiment of the present invention provides a rotary paraffin slicing device, including a base plate 1, a housing 2 fixedly connected to the upper surface of the base plate 1, a threaded rod 4 rotatably connected inside the housing 2, a handle 3 fixedly connected to the outer wall of the threaded rod 4, a sliding block 5 threadedly connected to the outer wall of the threaded rod 4, the outer wall of the sliding block 5 slidably connected to the inner wall of the housing 2, a support shaft 6 fixedly connected to the outer wall of the sliding block 5, a slicing blade 9 fixedly connected to the outer wall of the support shaft 6, a sliding shaft 7 slidably connected inside the sliding block 5, the outer wall of the sliding shaft 7 fixedly connected to the inner wall of the housing 2, a body 10 fixedly connected to the upper surface of the base plate 1, a hydraulic cylinder 11 fixedly connected to the upper interior of the body 10, a limit block 23 fixedly connected to the output end of the hydraulic cylinder 11, the outer wall of the limit block 23 slidably connected to the interior of the body 10, and a fixing component provided on the outer wall of the limit block 23 for fixing and clamping the paraffin block.

[0026] Specifically, in this embodiment, the base plate 1 fixes the position of the outer shell 2, the outer shell 2 supports the position of the threaded rod 4, and the threaded rod 4 fixes the position of the handle 3. Therefore, rotating the handle 3 causes the threaded rod 4 to rotate synchronously inside the outer shell 2. The rotation of the threaded rod 4 causes the threaded sliding block 5 to move within the limit of the outer shell 2. The movement of the sliding block 5 causes the support shaft 6 to move. The movement of the support shaft 6 causes another sliding block 5 to slide within a limit on the outer wall of the sliding shaft 7. At the same time, the outer shell 2 fixes the sliding shaft 7. The position of the slicing blade 9 is achieved by using two sliding blocks 5, which are supported by the support shaft 6 to move the blade back and forth. By moving the position of the slicing blade 9, the desired thickness of the slice can be cut, ensuring the uniformity and stability of the slice thickness. At the same time, the function of moving the slicing blade 9 allows the blade to be used evenly along its entire length, avoiding local wear, extending the blade's lifespan, and reducing the frequency and cost of replacement. The base plate 1 fixes the position of the machine body 10, and the machine body 10 supports the position of the hydraulic cylinder 11. Activating the hydraulic cylinder 11 causes the limiting block 23 to slide vertically within the machine body 10.

[0027] Please refer to Figures 1 and 4. The fixing assembly specifically includes a fixing plate 12. The outer wall surface of the fixing plate 12 is fixedly connected to the outer wall of the limiting block 23. A motor 13 is fixedly connected inside the fixing plate 12. A half gear 14 is fixedly installed at the output end of the motor 13. The outer wall of the half gear 14 is rotatably connected to the outer wall of the fixing plate 12. The tooth end of the half gear 14 is meshed with a second half gear 15. The limiting block 23 fixes the fixing plate 12 in position. The movement of the limiting block 23 drives the fixing plate 12 to move synchronously. The movement of the fixing plate 12 causes the clamped paraffin block to come into contact with the slicing blade 9, thereby achieving the effect of slicing the paraffin block. The fixing plate 12 also fixes and supports the position of the motor 13. Starting the motor 13 drives the half gear 14 to rotate synchronously under the support of the fixing plate 12. The rotation of the half gear 14 then drives the meshed half gear 15 to rotate.

[0028] Please refer to Figure 4. The inner part of the second half gear 15 is rotatably connected to the first fixed shaft 16. The outer wall of the first fixed shaft 16 is fixedly connected to the outer wall of the fixed plate 12. The outer walls of the first half gear 14 and the second half gear 15 are both fixedly connected to the first rotating plate 17. The inner part of the first rotating plate 17 is rotatably connected to the second connecting shaft 18. The outer wall of the second connecting shaft 18 is fixedly connected to the clamping block 20. The outer wall of the clamping block 20 is fixedly connected to the placement plate 21. The inner part of the clamping block 20 is fixedly connected to the first connecting shaft 8. The outer wall of the first connecting shaft 8 is rotatably connected to the second rotating plate 19. The inner part of the second rotating plate 19 is rotatably connected to the second fixed shaft 22. The outer wall of the second fixed shaft 22 is fixedly connected to the outer wall of the fixed plate 12.

[0029] Specifically, in this embodiment, the fixed shaft 16 supports the position of the second half gear 15, and the fixed plate 12 fixes the position of the fixed shaft 16. Therefore, the rotation of the first half gear 14 and the second half gear 15 drives the rotating plate 17 to rotate synchronously. The rotation of the rotating plate 17 can then drive the clamping block 20 to move horizontally via the connecting shaft 28. The clamping block 20 fixes the position of the placement plate 21, and thus the movement of the clamping block 20 can drive the placement plate 21 to move synchronously. The placement plate 21 then serves to place the paraffin block. The clamping block 20 serves to fix the position of the connecting shaft 8. Thus, when the clamping block 20 moves, the connecting shaft 8 drives the rotating plate 19 to rotate under the support of the fixed shaft 22. The fixed plate 12 fixes the position of the fixed shaft 22, and the rotating plate 19 supports and stabilizes the clamping block 20. The clamping reduces the shaking of the paraffin block, thereby reducing the wear of the slicing blade 9 and the transmission system, extending the service life of the equipment, reducing maintenance costs, reducing vibration and errors during the slicing process, and improving the slicing quality.

[0030] In use, when the position of the slicing blade 9 needs to be moved, firstly, rotating the handle 3 can drive the threaded rod 4 to rotate synchronously inside the outer shell 2. The rotation of the threaded rod 4 can drive the threaded sliding block 5 to slide under the limit of the outer shell 2. Then, the movement of the sliding block 5 can be driven by the support shaft 6 to drive another sliding block 5 to slide under the support of the sliding shaft 7. Thus, the two sliding blocks 5 can be supported by the support shaft 6 to drive the slicing blade 9 to move its position. By moving the slicing blade 9 horizontally, the position of the blade and the paraffin block can be precisely adjusted to ensure the uniformity and consistency of the slice thickness and meet the requirements of high-precision slicing. When it is necessary to fix the paraffin block in place, first place the paraffin block on the placement plate 21, then start the motor 13 to drive the first half gear 14 to rotate synchronously. The rotation of the first half gear 14 can drive the meshing second half gear 15 to rotate under the support of the fixed shaft 16. Thus, the joint rotation of the first half gear 14 and the second half gear 15 can drive the two rotating plates 17 to move. Then, the two rotating plates 17 can drive the clamping block 20 to move position via the connecting shaft 28. The movement of the clamping block 20 can drive the placement plate 21 to move synchronously. At the same time, the movement of the clamping block 20 can drive the two rotating plates 19 to move under the support of the fixed shaft 22 via the connecting shaft 18. The two rotating plates 19 support and stabilize the position of the clamping block 20. The movement of the clamping block 20 clamps and fixes the paraffin block placed on the placement plate 21. Then, the hydraulic cylinder 11 is activated, and the limiting block 23 drives the fixing plate 12 to move up and down. The movement of the fixing plate 12 causes the paraffin block placed on the placement plate 21 to come into contact with the slicing blade 9 to achieve the slicing effect. Thus, by clamping and fixing, the user can quickly and accurately adjust the position of the paraffin block, simplify the operation process, improve the slicing efficiency, and effectively prevent the paraffin block from flying out due to inertia during high-speed slicing, reducing the operation risk and ensuring the safety of the experimental personnel.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
