Technical Field
[0001] This application relates to the field of sintering furnace technology, and in particular to a sintering furnace for pathological blades. Background Technology
[0002] The scalpels used in medical devices refer to disposable medical pathology blades, which are mainly used in the examination of pathological tissue sections. Pathological tissue section examination is an important medical diagnostic method. It involves a series of processes on diseased tissues followed by observation under a microscope to clarify the nature, type, and extent of the disease, providing important evidence for clinical treatment. As an important tool in medical diagnosis, the performance of pathology blades directly affects the accuracy and efficiency of pathological sections. Currently, the production of pathology blades mainly includes material selection, molding, heat treatment (such as sintering), and grinding. Among these, the sintering process is the key step that determines the final performance of the blade.
[0003] Traditional sintering technology often uses box furnaces or continuous sintering furnaces, but these devices have significant shortcomings in terms of temperature uniformity and energy consumption control. Therefore, a pathology blade sintering furnace is proposed. Utility Model Content
[0004] The purpose of this application is to provide a sintering furnace for pathology blades, which can perform a more uniform sintering operation on the surface of pathology blades, ensure temperature uniformity, ensure sintering quality, and reduce energy consumption, thus solving the problems mentioned in the background art.
[0005] This application provides a pathology blade sintering furnace with the following technical solution: A pathology blade sintering furnace includes a furnace body, the furnace body having a circularly arranged heat-insulating cavity inside, a bottom plate fixedly connected to the top of the heat-insulating cavity, connecting seats arranged at equal intervals fixedly connected inside the bottom plate, and inner liner arranged at equal intervals fixedly connected to the bottom surface of the bottom plate. A sintering cavity is formed inside each inner liner, which is located directly below the connecting seats. Each connecting seat has a corresponding loading / unloading hole for the sintering cavity. A heating wire is provided inside the sintering cavity, the heating wire being serpentine and evenly arranged along the edge of the sintering cavity. A blade holder is placed inside the sintering cavity, and a blade is slidably inserted into the blade holder. The sintering cavity is a long rectangular shape adapted to the blade. The inner wall of the heat-insulating cavity has a heat-insulating layer, and the surface of each inner liner is covered with heat-insulating cotton.
[0006] By adopting the above technical solution, and by setting a long rectangular sintering cavity inside the inner liner that is compatible with the blade, and by setting heating wires evenly distributed in a serpentine pattern at the edge of the sintering cavity, a relatively uniform sintering operation can be performed on the surface of the pathology blade, ensuring temperature uniformity and sintering quality. By covering the outer side of the inner liner with heat insulation cotton and placing the inner liner inside a heat-insulating cavity with an inner wall insulation layer, heat loss inside the furnace can be effectively reduced, sintering efficiency can be improved, and energy consumption can be reduced.

[0008] By adopting the above technical solution, the temperature sensor can accurately detect the temperature inside the sintering chamber in real time and feed the data back to the controller. The controller automatically adjusts the output power of the heating wire by controlling the heating module according to the preset program and the feedback data, so that the sintering temperature is always within a suitable temperature range, avoiding the impact of excessively high or low temperatures on the sintering quality of the pathology blade, achieving precise temperature control, and further ensuring the sintering quality.

[0010] By adopting the above technical solution, the guide hole provides precise guidance for the insertion and removal of the tool holder. Operators can easily and accurately place the tool holder into or remove it from the sintering chamber through the guide hole, avoiding any deviation or tilting of the tool holder during placement, ensuring that the tool holder can accurately reach the designated position, and improving the convenience and accuracy of operation.
[0011] Preferably, the inner bottom wall of the sintering cavity is provided with a limiting groove, and the bottom of the tool holder is slidably inserted into the inner liner through the limiting groove.
[0012] By adopting the above technical solution, the tool holder will fall into the limiting groove after passing through the guide hole. The limiting groove plays a limiting role for the tool holder, improving the stability of the tool holder and the blade during the sintering process.

Before sintering, the cover plate can be quickly clamped and fixed on the upper surface of the connecting seat to seal the sintering cavity and reduce heat loss. After sintering, the cover plate can be quickly opened to remove the knife holder and blade, which improves the efficiency of operation. The heat insulation layer can effectively block the heat in the sintering cavity from being transferred upward, further improving the heat preservation effect in the furnace.
[0017] Preferably, the heat insulation layer can be configured as a flexible heat insulation felt.
[0018] By adopting the above technical solution, the flexible insulation felt has good flexibility and plasticity, which can fit well with the upper surface of the connecting seat to form a tight heat insulation layer, reduce heat conduction through the cover plate to the surrounding environment, and effectively reduce heat loss in the furnace.
[0019] Preferably, the insulation layer can be a ceramic fiber insulation board.
[0020] By adopting the above technical solution, ceramic fiber insulation board has the advantages of high temperature resistance, good thermal stability and low thermal conductivity. By setting ceramic fiber insulation board on the inner wall of the insulation cavity, it can effectively prevent heat loss from the furnace to the outside, reduce heat conduction and convection, and maintain the stability of the furnace temperature.
[0021] In summary, this application includes at least one of the following beneficial technical effects: This pathology blade sintering furnace features a rectangular sintering cavity adapted to the blade inside the inner liner, with serpentine heating wires evenly distributed along the edge of the sintering cavity. This allows for relatively uniform sintering of the pathology blade surface, ensuring temperature uniformity and sintering quality. By covering the outer liner with insulation cotton and placing the inner liner within an insulated cavity with an inner wall insulation layer, heat loss within the furnace is effectively reduced, sintering efficiency is improved, and energy consumption is lowered. Furthermore, by electrically connecting a temperature sensor and a heating module with a built-in power adjustment circuit to a controller, the output power of the heating wires can be automatically adjusted according to the detected temperature, ensuring the sintering temperature remains within a suitable range and further guaranteeing sintering quality.

[0025] Example 1: A sintering furnace for pathological blades, referring to... Figures 1-6 The furnace includes a furnace body 1, with a circular heat-insulating cavity 2 inside the furnace body 1. A base plate 3 is fixedly connected to the top of the heat-insulating cavity 2. Equally spaced connecting seats 4 are fixedly connected inside the base plate 3. Equally spaced inner liner 5 are fixedly connected to the bottom surface of the base plate 3. A sintering cavity 6 is opened inside the inner liner 5. The inner liner 5 is located directly below the connecting seats 4. Each connecting seat 4 has a pick-and-place hole 7 corresponding to the sintering cavity 6. A heating wire 9 is installed inside the sintering cavity 6. The heating wire 9 is serpentine and evenly arranged along the edge of the sintering cavity 6. A knife holder 10 is placed inside the sintering cavity 6. A blade 11 is slidably inserted inside the knife holder 10. The sintering cavity 6 is a long rectangular shape adapted to the blade 11. The inner wall of the heat-insulating cavity 2 is provided with a heat-insulating layer 12. Each inner liner 5 is covered with heat-insulating cotton 19.
[0026] The insulation layer 12 can be set as a ceramic fiber insulation board. The ceramic fiber insulation board has the advantages of high temperature resistance, good thermal stability and low thermal conductivity. Setting the ceramic fiber insulation board on the inner wall of the insulation cavity 2 can effectively prevent the heat in the furnace from being lost to the outside of the furnace, reduce the conduction and convection of heat, and maintain the stability of the furnace temperature.
[0027] Reference Figure 1 , Figure 4 and Figure 7The upper surface of the base plate 3 is fixedly connected with equidistant quick clamps 20 via a base. The clamping end of the quick clamps 20 is fixedly connected with a cover plate 21. The position of the cover plate 21 corresponds to the position of the connecting seat 4. The bottom surface of the cover plate 21 is fixedly connected with a heat insulation layer 8. The quick clamps 20 can realize the quick clamping and loosening operation of the cover plate 21. Before sintering, the cover plate 21 can be quickly clamped and fixed on the upper surface of the connecting seat 4 to seal the sintering cavity 6 and reduce heat loss. After sintering, the cover plate 21 can be quickly opened to remove the knife holder 10 and the blade 11, which improves the efficiency of operation. The heat insulation layer 8 can effectively block the heat in the sintering cavity 6 from being transferred upward, further improving the heat preservation effect in the furnace.
[0028] The insulation layer 8 can be set as a flexible insulation felt. The flexible insulation felt has good flexibility and plasticity, and can fit well with the upper surface of the connecting seat 4 to form a tight insulation layer 8, reducing heat conduction to the surrounding environment through the cover plate 21 and effectively reducing heat loss in the furnace.
[0029] Example 2: A sintering furnace for pathological blades, referring to... Figure 4 , Figure 5 and Figure 6 The base plate 3 is equipped with multiple heating modules 13 with built-in power adjustment circuits. The end of the heating wire 9 is connected to the heating module 13. Each inner liner 5 is equipped with a temperature sensor 14 for detecting the internal temperature of the sintering chamber 6. The upper surface of the furnace body 1 is equipped with a controller 15. The heating modules 13 and the temperature sensors 14 are electrically connected to the controller 15. The temperature sensors 14 can accurately detect the internal temperature of the sintering chamber 6 in real time and feed the data back to the controller 15. The controller 15 automatically adjusts the output power of the heating wire 9 by controlling the heating modules 13 according to the preset program and the feedback data, so that the sintering temperature is always within a suitable temperature range, avoiding the impact of excessively high or low temperatures on the sintering quality of the pathology blades, achieving precise temperature control, and further ensuring the sintering quality.
[0030] Reference Figure 4 , Figure 5 and Figure 6 The inner top of the inner liner 5 has a guide hole 16 that connects the sintering chamber 6 and the loading / unloading hole 7. The outer surface of the tool holder 10 is slidably connected to the inner wall of the guide hole 16. The guide hole 16 provides precise guidance for the insertion and removal of the tool holder 10. The operator can easily and accurately insert the tool holder 10 into or remove it from the sintering chamber 6 through the guide hole 16, avoiding the tool holder 10 from shifting or tilting during placement, ensuring that the tool holder 10 can accurately reach the designated position, and improving the convenience and accuracy of operation.
[0031] Reference Figure 5 and Figure 6A limiting groove 17 is provided on the inner bottom wall of the sintering chamber 6. The bottom of the tool holder 10 is slidably inserted into the inner liner 5 through the limiting groove 17. After the tool holder 10 passes through the guide hole 16, it will fall into the limiting groove 17. The limiting groove 17 plays a limiting role for the tool holder 10, improving the stability of the tool holder 10 and the blade 11 during the sintering process.
[0032] Reference Figure 5 and Figure 6 An auxiliary block 18 is fixedly connected to the top of the tool holder 10. An auxiliary hole is provided inside the auxiliary block 18. The auxiliary block 18 and the auxiliary hole provide convenience for the operator to pick up and put down the tool holder 10. The operator can insert an external tool into the auxiliary hole to put the tool holder 10 into or take out the sintering chamber 6, making the operation more convenient and improving the work efficiency.
[0033] The implementation principle of this application embodiment is as follows: The blade 11 to be sintered can be placed into the blade holder 10, and then the blade holder 10 can be placed into the sintering chamber 6 using an external tool. Finally, the top of the connecting seat 4 can be closed by the quick clamp 20 and the cover plate 21, and the heating wire 9 can be started to perform the sintering operation. During the sintering operation, the heat insulation cotton 19 covering the surface of the inner liner 5 can enhance the heat insulation effect and reduce the heat loss from the surface of the inner liner 5. The heat insulation layer 12 set on the inner wall of the heat insulation chamber 2 can effectively prevent the heat in the furnace from being lost to the outside of the furnace, reduce heat conduction, maintain the temperature stability in the furnace, improve sintering efficiency, and reduce energy consumption. The long rectangular sintering chamber 6 adapted to the blade 11 can ensure that the heating space of each part of the blade 11 is uniform and consistent, avoiding uneven heating of the blade 11 due to unreasonable cavity shape, thus providing a basic condition for uniform sintering. The heating wires 9, arranged in a serpentine pattern, can uniformly heat the blade 11, ensuring a relatively uniform sintering process on the surface of the blade 11 and guaranteeing temperature uniformity, thereby ensuring sintering quality. The temperature sensor 14 can detect the temperature inside the sintering chamber 6 in real time and feed the temperature data back to the controller 15. The controller 15, based on the preset program and feedback data, automatically adjusts the output power of the heating wires 9 by controlling the heating module 13 with the built-in power adjustment circuit, so that the sintering temperature is always within a suitable temperature range, avoiding the impact of excessively high or low temperatures on the sintering quality of the blade 11, achieving precise temperature control, and further ensuring sintering quality. After sintering, the cover plate 21 can be opened by the quick clamp 20, and then the blade holder 10 can be removed from the sintering chamber 6 by inserting an external tool into the auxiliary hole of the auxiliary block 18, which is convenient and quick.
