Description

Technical Field

[0001] This utility model relates to the field of HE dyeing machine technology, specifically to a feeding and heating mechanism for a drip HE dyeing machine. Background Technology

[0002] Staining is of great significance in the diagnosis of pathological tissue morphology, scientific experimental research, and teaching. Without staining tissue sections, the internal structure of the tissue cannot be seen, and the cell nuclei cannot be identified. Therefore, researchers cannot provide a basis for judgment to determine whether the tissue is abnormal.

[0003] HE staining uses hematoxylin and eosin to stain the nucleus and cytoplasm, respectively, to distinguish the morphology of normal cells. In practical applications, it can identify abnormal pathological changes such as tissue cell necrosis, edema, degeneration, and inflammatory cell infiltration.

[0004] Current technology for staining tissue sections mostly relies on manual operation, resulting in low processing efficiency. To facilitate staining, the tissue sections are typically heated to a certain temperature before staining. Therefore, it is necessary to design a device that can feed materials into the HE staining machine and heat the tissue sections. Utility Model Content

The feeding mechanism includes a feeding lifting module connected to the machine base. A feeding tray is provided on the output end of the feeding lifting module. The feeding tray is used to place a material hopper containing tissue sections. The feeding lifting module can drive the tray to move up and down, thereby causing the material hopper to extend into or out of the heating mechanism. The heating mechanism is used to heat the tissue sections in the material hopper. The feeding push mechanism is connected to the feeding mechanism and the material hopper channel respectively, and is used to push the material hopper on the feeding tray into the material hopper channel.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0021] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, a feeding and heating mechanism 2 for a hematoxylin and eosin (HE) staining machine is disclosed. The HE staining machine includes a machine base 100, on which a material hopper channel 200 is provided. The material hopper channel 200 is used to transport a material hopper containing tissue sections. The feeding and heating mechanism 2 includes a feeding mechanism 1, a heating mechanism 2, and a feeding pushing mechanism 3, all respectively disposed on the machine base 100. The feeding mechanism 1 is connected to both the heating mechanism 2 and the feeding pushing mechanism 3. During processing, the manual operator first places the material hopper containing the tissue sections onto the feeding mechanism 1, then the feeding mechanism 1 lifts the material hopper to the heating position of the heating mechanism 2. The heating mechanism 2 heats the tissue sections in the material hopper. After heating, the feeding mechanism 1 lowers the material hopper to a height suitable for the material hopper channel 200. Finally, the feeding pushing mechanism 3 pushes the material hopper into the material hopper channel 200, thus completing the heating and feeding process.

[0024] like Figure 2 As shown, the feeding mechanism 1 includes a feeding base 11 and a feeding tray 12. The feeding base 11 is fixedly connected to the machine base 100, and a feeding lifting motor 13 is fixedly installed on the feeding base 11. The output end of the feeding lifting motor 13 is connected to a feeding lifting screw 14. A feeding lifting slider 15 is sleeved on the feeding lifting screw 14. A lifting plate 16 is fixedly installed at the bottom of the feeding tray 12, and the lifting plate 16 is fixedly connected to the feeding lifting slider 15. During processing, the operator first places the hopper containing tissue slices onto the feeding tray 12; then, by controlling the operation of the feeding lifting motor 13, the operator can drive the feeding lifting slider 15 to slide up and down on the feeding lifting screw 14. The feeding lifting slider 15 drives the lifting plate 16 and the feeding tray 12 to move together, so that the feeding tray 12 can drive the hopper to extend into or out of the heating mechanism 2.

[0025] To limit and guide the lifting movement of the feeding tray 12, lifting guide sleeves 17 are respectively provided at the four corners of the lifting plate 16. Lifting guide rods 18 are respectively provided on the feeding fixed seat 11 at corresponding positions to each lifting guide sleeve 17. The lifting guide rods 18 pass through the corresponding lifting guide sleeves 17, and the two are slidably engaged. When the feeding lifting motor 13 is working, the lifting plate 16 drives the lifting guide sleeves 17 to slide on the lifting guide rods 18, thereby guiding and limiting the lifting plate 16.

[0026] In other embodiments, the number of lifting guide rods 18 can also be any other number; it is only necessary to ensure that the lifting guide rods 18 and the lifting guide sleeves 17 are set in a one-to-one correspondence.

[0027] like Figure 1 As shown, the heating mechanism 2 includes a heating frame 21, which is fixedly connected to the machine base 100. A baking oven 22 is fixedly installed on the heating frame 21, and the baking oven 22 is positioned directly above the feeding tray 12. The lower end of the baking oven 22 has a hollow structure, allowing the feeding tray 12 to lift the material hopper and extend it into the baking oven 22. The baking oven 22 then heats the tissue sections inside the hopper, ensuring uniform heating of the tissue sections. The baking oven 22 can be any existing type; its specific structure will not be described in detail here.

[0028] like Figure 3 As shown, the feeding and pushing mechanism 3 includes a feeding fixing frame 31, which is connected to the machine base 100. A feeding motor 32 and two feeding driven wheels 33 are mounted on the feeding fixing frame 31, with the two driven wheels 33 located at opposite ends of the feeding fixing frame 31. A feeding drive wheel 34 is mounted on the output end of the feeding motor 32. A feeding drive belt 35 is sleeved on the feeding drive wheel 34 and the feeding driven wheels 33, and a feeding pushing block 36 is fixedly mounted on the feeding drive belt 35. After the tissue sections are heated, the feeding lifting motor 13 drives the feeding tray 12 to descend to a height suitable for the material flow channel 200; then, it controls the feeding motor 32 to operate, driving the feeding pushing block 36 to move. The feeding pushing block 36 connects with the material hopper on the feeding tray 12, thereby pushing the material hopper to slide on the feeding tray 12 until the material hopper, carrying the tissue sections, is pushed into the material flow channel 200.

[0029] To limit and guide the movement of the feeding push block 36, a feeding guide rail 37 is provided on the feeding fixing frame 31, and a feeding push slider 38 is provided at the bottom of the feeding push block 36. The feeding push slider 38 is slidably engaged with the feeding guide rail 37. When the feeding motor 32 is working, the feeding push block 36 will drive the feeding push slider 38 to slide on the feeding guide rail 37. Through the engagement of the two, the movement direction of the feeding push block 36 is limited and guided, improving the stability of the feeding process and ensuring that the feeding push block 36 can push the hopper into the hopper flow channel 200.

[0030] To improve transmission stability, a rotatable belt tensioner 39 is provided on the pusher fixing frame 31. The belt tensioner 39 is detachably connected to the pusher fixing frame 31, and the pusher drive belt 35 is sleeved on the belt tensioner 39. The belt tensioner 39 is used to adjust the transmission tension of the pusher drive belt 35 to ensure the stability of the feeding process.

[0031] Working principle: The hopper containing tissue sections is manually placed onto the feeding tray 12. The feeding lifting motor 13 is started, which drives the feeding lifting slider 15 and lifting plate 16 to rise via the feeding lifting screw 14, so that the feeding tray 12 carrying the hopper enters the baking oven 22 for heating. After heating is completed, the feeding lifting motor 13 reverses, causing the hopper to descend to its initial position. The pushing motor 32 is started, which pushes the feeding push block 36 along the feeding guide rail 37 via the pushing drive belt 35, pushing the hopper from the feeding tray 12 into the hopper flow channel 200, completing the feeding process.

[0032] This invention not only improves the automation of the HE staining process, but also optimizes the pretreatment effect before staining by integrating a heating function, making it suitable for high-throughput staining applications in pathological histology.

[0033] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
