Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for biological research, specifically a slicing device for biological research and development. Background Technology

[0002] In the field of biomedical research, precise slicing of biological samples is an indispensable step in many experiments. High-quality slices provide essential basic materials for subsequent microscopic observation, pathological analysis, and molecular biology research. With the development of science and technology, the quality requirements for biological sample slices are becoming increasingly stringent. Not only must the slice thickness be uniform, but the integrity of the sample's internal structure must also be preserved. While traditional manual slicing methods are flexible, they are inefficient, lack precision, and have poor reproducibility, making them unsuitable for the demands of modern scientific research.

[0003] To address the aforementioned shortcomings, the existing Chinese patent CN212331170U, entitled "A Slicing Device for Biological Research and Development," provides a method for pushing slices. However, it still has certain drawbacks in its use. Firstly, it only pushes directly through a push rod during the driving process, without any auxiliary fixing or locking effect, resulting in insufficient slicing accuracy. Secondly, the cutting effect of the slicing blade is unstable, leading to inconsistent thickness of the cut samples during the slicing process. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a slicing device for biological research and development, thereby improving the deficiencies of insufficient slicing precision and insufficient slice thickness in common slicing devices on the market.

[0008] Furthermore, the drive assembly also includes: a positioning groove formed on the top of the drive slide rail, with multiple positioning teeth on the inner walls of both sides of the positioning groove; a positioning block disposed between the drive block and the push plate, with insert blocks slidably connected to both sides of the positioning block, and a traction spring disposed between the insert blocks and the positioning block; and an electromagnet disposed on the inner wall of the positioning groove, wherein the electromagnet and the insert blocks are magnetically attracted to each other, and the insert blocks engage with the positioning teeth when attracted by the electromagnet.

[0009] Furthermore, guide grooves are provided on the inner walls of both sides of the cutting table, and guide blocks are provided on both sides of the tool holder, with the guide blocks and guide grooves being slidably connected.

[0010] Furthermore, multiple auxiliary wheels are rotatably connected to both sides of the guide block via bearings, and the auxiliary wheels are in contact with the inner wall of the guide groove.

[0011] Furthermore, a control panel is provided on one side of the workbench, and the control panel is electrically connected to the drive motor, electromagnet and electric push rod.

[0012] This invention provides a slicing device for biological research, which has the following advantages:

[0013] The advantage of this invention is that, through the driving component and auxiliary fixing effect, the stability of the material during the pushing process is improved, the possibility of material deviation is reduced, thereby ensuring the consistency and accuracy of each slice.

[0024] This application provides a slicing device for biological research. This device, through a driving component and auxiliary fixing effect, improves the stability of the material during the pushing process, reduces the possibility of material deviation, and thus ensures the consistency and accuracy of each slice. This not only improves the precision of the slices but also enhances the repeatability of experimental results. The cutting component, in conjunction with the guide groove and auxiliary wheels, ensures the smooth vertical movement of the cutting blade holder, maintaining a consistent speed and pressure during the slicing process, thereby obtaining slices of uniform thickness and improving slice quality. The following provides a detailed description of this slicing device for biological research. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Please see Figure 1-6 In this embodiment, a slicing device for biological research and development is provided, including: a worktable 1 with a support foot at the bottom of the other end; a push plate 3 with an overall "L"-shaped structure and two limiting rods 301 on one side; a drive assembly with a drive assembly on the top of the worktable 1 for pushing the push plate 3 to move and pushing the material; and a cutting assembly with a cutting assembly on the top of the worktable 1 for slicing the material.

[0027] During use, the workbench 1 serves as the basic platform of the device, used to install the push plate 3, drive components, and cutting components. The bottom of the workbench is equipped with support feet to ensure the stability of the entire device, providing a sturdy and stable working platform that lays the foundation for all subsequent operations and ensures the safety and reliability of the equipment during operation. Meanwhile, the push plate 3 has an "L"-shaped structure with two limiting rods 301 on one side. When the material is placed on the workbench, the limiting rods fix the position of the material to prevent it from shifting during the pushing process, ensuring the consistency and stability of the material position, improving the accuracy and repeatability of the slicing process, and helping to obtain higher quality experimental samples.

[0028] Furthermore, the drive assembly includes: a drive slide rail 101 located on the top of the worktable 1, a drive motor 102 located on the inner wall of one side of the drive slide rail 101, a drive rod 103 connected to one side of the drive motor 102 via a drive shaft, and the end of the drive rod 103 being rotatably connected to the drive slide rail 101 via a ball bearing; and a drive block 302 located at the bottom of the push plate 3, with the drive rod 103 and the drive block 302 being threadedly engaged.

[0029] During use, after the drive motor 102 is started, the drive rod 103 rotates and drives the push plate 3 to move along the drive slide rail 101. At this time, the push plate 3 can push the material to move and assist in feeding and cutting, realizing material pushing under automated control. This not only improves work efficiency, but also reduces errors caused by manual operation, ensuring that each cut achieves a consistent effect.

[0030] Furthermore, the drive assembly also includes: a positioning groove 104 formed on the top of the drive slide rail 101, with multiple positioning teeth 105 on the inner walls of both sides of the positioning groove 104; a positioning block 303 located between the drive block 302 and the push plate 3, with insert blocks 304 slidably connected to both sides of the positioning block 303, and a traction spring 305 between the insert blocks 304 and the positioning block 303; and an electromagnet 106 located on the inner wall of the positioning groove 104, with the electromagnet 106 and the insert blocks 304 magnetically attracted to each other, and the insert blocks 304 engaging with the positioning teeth 105 when attracted by the electromagnet 106.

[0031] During use, when the push plate 3 needs to be precisely positioned after moving to the corresponding position, the electromagnet 106 is activated through the control panel 4 to attract the insertion block 304 to extend and engage with the positioning teeth 105 in the positioning groove 104, thereby locking the current position of the push plate 3. The insertion blocks 304 on both sides of the positioning block 303 are kept in the retracted state by the traction spring 305, thus completing the locking and positioning. This increases the system's ability to lock at specific positions and further improves the positional accuracy during the cutting process, which is beneficial for completing experimental tasks with high precision requirements.

[0032] Furthermore, a control panel 4 is provided on one side of the workbench 1. The control panel 4 is electrically connected to the drive motor 102, the electromagnet 106 and the electric push rod 204. During use, the control panel 4 can provide convenient control and improve the ease of use of the device.

[0033] Furthermore, the cutting assembly includes: a cutting table 2 located on top of the workbench 1, a blade holder 202 slidably connected inside the cutting table 2, and a cutting blade 203 located at the bottom of the blade holder 202; and an electric push rod 204 located on the inner wall of the top of the cutting table 2, with the bottom of the electric push rod 204 connected to the cutting blade 203.

[0034] During use, the blade holder 202 is slidably connected inside the cutting table 2, and the cutting blade 203 is installed at the bottom of the blade holder 202. The electric push rod 204 acts downward from the inner wall of the top of the cutting table to control its up and down movement to complete the cutting action. This design allows for precise control of the cutting depth and speed, which helps to obtain high-quality biological sample slices with uniform thickness and supports more detailed research and analysis.

[0035] Furthermore, guide grooves 201 are provided on the inner walls of both sides of the cutting table 2, and guide blocks 205 are provided on both sides of the tool holder 202. The guide blocks 205 are slidably connected to the guide grooves 201. Multiple auxiliary wheels 206 are rotatably connected to the two sides of the guide blocks 205 through bearings, and the auxiliary wheels 206 are in contact with the inner wall of the guide grooves 201.

[0036] During use, the auxiliary wheel 206 fits against the inner wall of the guide groove 201, ensuring that the tool holder moves smoothly and steadily in the vertical direction. This reduces the resistance caused by friction during cutting, improves the smoothness and stability of the cutting action, and helps to improve the quality of the final product.
