Description

Technical Field

[0001] This utility model relates to the field of paraffin slice technology, specifically a paraffin slicer. Background Technology

[0002] As is well known, paraffin sectioning is the most widely used method in routine histological slide preparation. Paraffin sections are not only used to observe the morphology and structure of normal cells and tissues, but are also the main method used in disciplines such as pathology and forensic medicine to study, observe, and judge morphological changes in cells and tissues. Moreover, they are also widely used in research in many other disciplines.

[0003] Chinese Patent No. CN220854341U discloses a paraffin slicer, which includes a main body device for fixing paraffin wax for slicing, and a conveying device at the front of the main body device for conveying and collecting the paraffin wax slices after slicing. This paraffin slicer, through its post-slicing conveying and collection mechanism, automatically transfers the paraffin wax slices downwards, simplifying operation and improving slicing efficiency.

[0004] In practical applications, the devices corresponding to the aforementioned technologies have significant shortcomings. When the equipment is not in use, the processing area lacks an effective protective sealing mechanism, making it easy for dust and impurities from the external environment to adhere to this area. Before the equipment is put back into use, operators need to spend extra time and effort to clean the adhered dust and impurities, which not only increases the complexity of operation but also reduces work efficiency. Furthermore, due to the lack of protection, the processing area is also susceptible to damage from external impacts when not in use, seriously affecting the service life and ease of normal use of the equipment. Therefore, it is necessary to provide a paraffin slicer to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a paraffin slicer to solve the problems mentioned in the background art.

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

[0025] Please see Figures 1-4One embodiment provided by this utility model:

[0026] A paraffin slicer, comprising:

[0027] The slicer body 1 has a processing mechanism 2 on its front side. Both sides of the top of the slicer body 1 are fixedly installed with longitudinal guide rails 3. A threaded rod 4 is rotatably installed inside the longitudinal guide rail 3. An adjusting block 5 is sleeved on the outer wall of the threaded rod 4 and is slidably installed on the longitudinal guide rail 3. A vertical rod 6 is fixedly installed on the top of each of the two adjusting blocks 5. A horizontal plate 7 is fixedly installed between the tops of the two vertical rods 6. An electric telescopic rod 9 is fixedly installed on the top of the horizontal plate 7. The drive end of the electric telescopic rod 9 passes through the horizontal plate 7 and extends to the bottom of the horizontal plate 7. A visual protective cover 10 is fixedly installed on the drive end of the electric telescopic rod 9.

[0028] A sealing gasket is adhered to the back side of the visual protective cover 10;

[0029] A fixed frame 13 is fixedly installed on one side of the back of the slicer body 1, and a drive mechanism is provided on the fixed frame 13.

[0030] The visual protective cover 10 has mounting brackets 11 fixedly installed on both sides of the lower front. The top of the mounting bracket 11 is rotatably connected to the light-filling plate 12 via a damping shaft. Several LED beads 16 are fixedly installed at the bottom of the light-filling plate 12. The angle of the light-filling plate 12 can be flexibly adjusted via the damping shaft. The LED beads 16 can provide supplementary light as needed, making it convenient to observe the real-time processing status.

[0031] In one embodiment, stabilizer bars 8 are fixedly installed on both sides of the top rear of the visual protective cover 10. The horizontal plate 7 has sliding holes corresponding to the position and number of stabilizer bars 8, and the horizontal plate 7 is slidably connected to the stabilizer bars 8 through the sliding holes, thereby enhancing the movement stability of the visual protective cover 10 and ensuring its smooth operation.

[0032] In one preferred embodiment, the drive mechanism includes a servo motor 15, which is fixedly mounted on the mounting bracket 13. The rear ends of the two threaded rods 4 pass through the longitudinal guide rail 3 and extend to the back of the longitudinal guide rail 3. A transmission mechanism 14 is provided between the two threaded rods 4. The drive end of the servo motor 15 is fixedly connected to the rear end of one of the threaded rods 4, thereby realizing automatic longitudinal position adjustment of the visual protective cover 10.

[0033] In one embodiment, the transmission mechanism 14 consists of a driving gear, a driven gear, and a synchronous belt. The driving gear and the driven gear are connected by meshing transmission through the synchronous belt. The driving gear and the driven gear are respectively fixedly installed on the outer wall of the rear end of the two threaded rods 4, so as to realize the synchronous rotation of the two threaded rods 4, ensure the synchronous movement of the adjusting block 5, and make the visual protective cover 10 move smoothly, thus ensuring the stability and accuracy of the protective adjustment.

[0034] In one preferred embodiment, the adjusting block 5 has a threaded hole that matches the threaded rod 4, and the adjusting block 5 is threadedly connected to the threaded rod 4 through the threaded hole, so that the adjusting block 5 can move stably with the rotation of the threaded rod 4, providing a stable drive for the movement of the visual protective cover 10.

[0035] The working principle of this utility model is as follows: When the slicer body 1 is not in use, the servo motor 15 is first started, and its drive end drives a threaded rod 4 to rotate. Through the transmission mechanism 14, the two threaded rods 4 rotate synchronously. Based on the threaded transmission between the threaded rod 4 and the adjusting block 5, and the sliding cooperation between the adjusting block 5 and the longitudinal guide rail 3, the two adjusting blocks 5 can move longitudinally stably and synchronously. The movement of the adjusting block 5 drives the vertical rod 6 to move, and the movement of the vertical rod 6 drives the electric telescopic rod 9 to move through the horizontal plate 7. The movement of the electric telescopic rod 9 then drives the visual protective cover 10 to move forward to the top of the processing mechanism 2. Subsequently, the electric telescopic rod 9 is controlled to work, and its drive end drives the visual protective cover 10 to move vertically, moving it downward until the area where the processing mechanism 2 is located is completely covered inside the visual protective cover 10. At this time, the back of the visual protective cover 10 is tightly attached to the front of the slicer body 1 to ensure the sealing effect at the connection between the two. By automatically adjusting the visual protective cover 10 to the outside of the processing mechanism 2, the processing mechanism 2 can be sealed and protected when the slicer body 1 is idle, effectively preventing interference from external dust and impurities, and providing good protection to ensure the stable operation of the slicer body 1. In addition, when the slicer body 1 is in use, the visual protective cover 10 can be adjusted to the top of the slicer body 1 without affecting the processing area where the processing mechanism 2 is located.

[0036] When the slicer body 1 is in use and the visualization cover 10 is located on top of the slicer body 1, the supplementary lighting plate 12, which was originally parallel to the front of the visualization cover 10, is rotated to form an angle with the visualization cover 10, thereby positioning the supplementary lighting plate 12 above the processing mechanism 2. Then, the LED beads 16 at the bottom of the supplementary lighting plate 12 are turned on to provide supplementary lighting to the processing area where the processing mechanism 2 is located, thereby improving the lighting environment of the processing area where the workers are located and providing them with a clearer view. Furthermore, the supplementary lighting plate 12 is highly convenient to use. Utilizing its rotatable characteristic, when not in use, the supplementary lighting plate 12 can be folded to a position parallel to the front of the visualization cover 10; when needed, it can simply be unfolded outwards, making operation simple and efficient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
