Description

Technical Field

[0001] This utility model belongs to the technical field of slicing and scraping devices, specifically relating to a paraffin slicing and scraping device. Background Technology

[0002] Paraffin wax, also known as crystalline wax, is a mixture of hydrocarbons with approximately 18 to 30 carbon atoms. The purpose of paraffin sectioning is to obtain a complete thin tissue section that can be used for microscopic observation. Paraffin sections are usually processed by a section scraping device, and the existing section scraping device is the equipment used for section scraping when obtaining thin tissue from paraffin.

[0003] In existing slicing and scraping devices, when processing paraffin wax, the auxiliary electric cylinder drives the slicing and scraping blade downwards to cut the paraffin wax. After the slicing and scraping blade cuts the paraffin wax, a small amount of paraffin wax easily adheres to the side of the blade, and it is not easy to clean the adhered paraffin wax. When more and more of the wax accumulates, it makes slicing processing inconvenient, and may even prevent slicing work from continuing. This affects the convenience of cleaning the slicing and scraping blade when processing paraffin wax. To address this issue, this utility model proposes a paraffin wax slicing and scraping device. Utility Model Content

[0004] The purpose of this utility model is to provide a paraffin slicing scraping device to solve the problem mentioned in the background art that after the slicing scraper cuts paraffin, a small amount of paraffin easily adheres to the side of the slicing scraper, and it is not easy to clean the adhered paraffin. When it accumulates more and more, it causes inconvenience in slicing and may even make it impossible to continue slicing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paraffin wax slicing and scraping device, comprising a base and a slicing and scraping blade, wherein a feeding slit is provided at the front end of the upper surface of the base, the lower surface of the slicing and scraping blade is on the same vertical line as the inner surface of the feeding slit, a push plate is installed at the rear end of the upper surface of the base via a main electric cylinder, a scraping and cleaning mechanism is provided on the outer surface of the slicing and scraping blade, and a thickness adjustment mechanism is provided on the front surface of the base on one side of the feeding slit;

[0006] The scraping and cleaning mechanism includes a drive connection assembly disposed on the outer surface of the slicing scraper, scraping and cleaning components disposed on both sides inside the drive connection assembly, and a clamping connection assembly disposed between the scraping and cleaning components and the drive connection assembly;

[0008] Preferably, a top frame is fixedly installed on the upper surface of the base, and a sliding seat is slidably mounted on the top of the top frame through a sliding groove. A main electric cylinder is fixed inside the top frame, and the bottom end of the main electric cylinder is fixed to the middle position of the upper surface of the slicing scraper by bolts.

[0009] Preferably, the drive connection assembly includes a lifting frame disposed on the outer surface of the slicing scraper, and auxiliary electric cylinders are fixedly installed on both sides of the top end of the slicing scraper. The movable end of the auxiliary electric cylinder is fixed to the upper surface of the lifting frame by bolts.

[0010] Preferably, the scraping and cleaning assembly includes cleaning push plates disposed on both sides of the slicing scraper, the inner surface of the cleaning push plates being in contact with the surface of the slicing scraper.

[0011] Preferably, the compression connection assembly includes slide rods that are equidistantly slidably connected to both sides of the lifting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a scraping and cleaning mechanism, when paraffin wax adheres to the surface of the slicing and scraping blade during slicing and scraping, two auxiliary electric cylinders move simultaneously to move the lifting frame downwards. During downward movement, the compression spring deforms, causing the cleaning push plate to press tightly against the surface of the slicing and scraping blade. This ensures that the cleaning push plate is always in contact with the surface of the slicing and scraping blade as it moves downwards, scraping away the paraffin wax adhering to the surface. This makes cleaning convenient. If cleaning is not required, the plate can be placed directly on top of the outer surface of the slicing and scraping blade without affecting the operation. This improves the convenience of the slicing and scraping device in scraping and cleaning the surface of the slicing and scraping blade during paraffin slicing and scraping.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a paraffin slicing and scraping device, including a base 101 and a slicing and scraping blade 102. The upper surface of the base 101 has a feeding cut 107 at the front end. The lower surface of the slicing and scraping blade 102 and the inner surface of the feeding cut 107 are on the same vertical line. The upper surface of the base 101 has a push plate 106 installed at the rear end through a main electric cylinder.

[0025] A top frame 105 is fixedly installed on the upper surface of the base 101. A slide block 103 slides on the top of the top of the top frame 105 through a sliding groove. A main electric cylinder 104 is fixed inside the top frame 105. The bottom of the main electric cylinder 104 is fixed to the middle position of the upper surface of the slicing scraper 102 by bolts.

[0026] The outer surface of the slicing and scraping blade 102 is provided with a scraping and cleaning mechanism. The scraping and cleaning mechanism includes a drive connection assembly provided on the outer surface of the slicing and scraping blade 102. Scraping and cleaning components are provided on both sides inside the drive connection assembly. A clamping connection assembly is provided between the scraping and cleaning components and the drive connection assembly. When paraffin wax is attached to the surface of the slicing and scraping blade 102 during slicing or scraping, the scraping and cleaning mechanism can contact the surface of the slicing and scraping blade 102 and move to clean it.

[0027] In order to facilitate the lifting and adjusting of the cleaning push plate 1024 for cleaning via the drive connection assembly, in this embodiment, preferably, the drive connection assembly includes a lifting frame 1022 disposed on the outer surface of the slicing scraper 102, and auxiliary electric cylinders 1021 are fixedly installed on both sides of the top end of the slicing scraper 102. The movable end of the auxiliary electric cylinders 1021 is fixed to the upper surface of the lifting frame 1022 by bolts, so that the two auxiliary electric cylinders 1021 can move simultaneously to drive the lifting frame 1022 and the cleaning push plate 1024 to rise and fall for cleaning.

[0028] In order to facilitate the scraping and cleaning of residual paraffin on the surface of the slicing scraper 102 by means of the scraping and cleaning assembly, in this embodiment, preferably, the scraping and cleaning assembly includes cleaning push plates 1024 disposed on both sides of the slicing scraper 102. The inner surface of the cleaning push plate 1024 is in contact with the surface of the slicing scraper 102, and the cleaning push plate 1024 can be pressed tightly on the surface of the slicing scraper 102, and the cleaning push plate 1024 can be moved on the surface of the slicing scraper 102 for cleaning.

[0029] To facilitate the cleaning of the surface of the slicing scraper 102 by pressing the cleaning push plate 1024 against the slicing scraper 102 using the pressing connection assembly, in this embodiment, preferably, the pressing connection assembly includes slide rods 1023 that are equidistantly slidably connected to both sides of the lifting frame 1022. The ends of the slide rods 1023 are fixed to the surface of the cleaning push plate 1024 by screws. A compression spring 1025 is fitted and installed between the cleaning push plate 1024 and the lifting frame 1022 on the outer surface of the slide rods 1023. The compression spring 1025 deforms and drives the cleaning push plate 1024 to press against the surface of the slicing scraper 102 through the slide rods 1023, facilitating the pressing and moving cleaning process.

[0030] A thickness adjustment mechanism is provided on the front surface of the base 101 on one side of the cutting opening 107. The thickness adjustment mechanism includes a thickness adjustment component on the front surface of the base 101. Limit control components are provided at both ends of the thickness adjustment component. When the paraffin is cut on the upper surface of the base 101, the thickness adjustment mechanism can be used to adjust the thickness of the slice for precise slicing.

[0031] To facilitate thickness adjustment of the slices using the thickness adjustment component, in this embodiment, preferably, the thickness adjustment component includes an end frame 1011 welded and fixed to the front surface of the base 101. An adjusting threaded rod 1012 is threadedly connected to the middle position of the end frame 1011. A backing plate 1013 is provided on the upper surface of the base 101 on one side of the unloading cut 107. The end of the adjusting threaded rod 1012 is connected to the inside of the backing plate 1013 through a bearing. During cutting, the adjusting threaded rod 1012 can be held by hand to move the backing plate 1013 on the surface of the base 101, so that the inner surface of the backing plate 1013 is at the cutting thickness with the inner side of the unloading cut 107, thus facilitating control of the slice thickness.

[0032] In order to facilitate the stable movement and adjustment of the abutment plate 1013 through the limit control component, in this embodiment, preferably, the limit control component includes a limit slide groove 1014 formed on both sides of one end inside the base 101, and a limit slider 1015 integrally provided at both ends of the abutment plate 1013 that slides with the limit slide groove 1014, so that the limit slider 1015 can be driven to slide and control inside the limit slide groove 1014 when the abutment plate 1013 is moved and adjusted.

[0033] The working principle and usage process of this utility model are as follows: When using this paraffin slicing and scraping device, the bottom end of the base 101 is first placed stably on the ground at the usage position. During use, the adjusting threaded rod 1012 is held by hand and rotated to move the abutment plate 1013 on the upper surface of the base 101. When the abutment plate 1013 moves, the end of the limiting slider 1015 slides and controls the movement inside the limiting groove 1014, so that the inner surface of the abutment plate 1013 moves to the position of the material cutting 107. The distance between the inner surface of the material cutting 107 and the inner surface of the abutment plate 1013 is adjusted to the thickness of the slice, so that the slice thickness can be accurately controlled when slicing paraffin, and the convenience of adjusting the slice thickness during paraffin cutting and scraping is improved.

[0034] Then, when the paraffin is cut after the thickness is adjusted, the main electric cylinder 104 drives the slide 103 and the slicing scraper 102 to the end. The lower surface of the slicing scraper 102 corresponds to one side of the inside of the feeding cut 107. The paraffin is placed on the upper surface of the base 101, and the top of the paraffin contacts the surface of the abutment plate 1013. The tail of the paraffin contacts the push plate 106. The auxiliary electric cylinder 2 drives the slicing scraper 102 to move down to process the paraffin slice. The sliced ​​paraffin falls directly from the feeding cut 107 to the bottom and then from the end, which facilitates slicing. After one slicing is completed, the main electric cylinder 2 drives the push plate 106 and the paraffin to abut the end of the abutment plate 1013 again to continue slicing. When scraping is required, the paraffin is positioned on the surface of the base 101 directly through the abutment plate 1013 and the push plate 106. The slicing scraper 102 contacts the surface of the paraffin. When the main electric cylinder 104 drives the slide 103 and the slicing scraper 102 to move, the surface of the paraffin is scraped.

[0035] Finally, when paraffin wax adheres to the surface of the slicing and scraping blade 102 during the slicing and scraping process, the two auxiliary electric cylinders 1021 move simultaneously, causing the lifting frame 1022 to move downward. When the lifting frame 1022 moves downward, the compression spring 1025 deforms, causing the cleaning push plate 1024 to press tightly against the surface of the slicing and scraping blade 102. This ensures that the cleaning push plate 1024 is always in contact with the surface of the slicing and scraping blade 102 as it moves downward and scrapes off the paraffin wax adhering to the surface. This makes cleaning convenient. If cleaning is not required, the plate can be placed directly on the top of the outer surface of the slicing and scraping blade 102 without affecting the operation. This improves the convenience of the slicing and scraping device for scraping and cleaning the surface of the slicing and scraping blade 102 during the paraffin slicing and scraping process.
