Description

Technical Field

[0001] This utility model relates to the field of materials preparation technology, and in particular to a processing device for an Ag-containing titanium-based high-entropy alloy antibacterial material. Background Technology

[0002] With the increasing aging population, the number of osteoarthritis patients is rising year by year, leading to a continuous increase in demand for artificial joint replacement surgery. Traditional titanium alloy and cobalt-chromium-molybdenum alloy prostheses suffer from two major problems: excessively high elastic modulus and lack of inherent antibacterial properties, which seriously affect surgical outcomes and patient prognosis. In recent years, Ag-containing titanium-based high-entropy alloys (Ti-Zr-Nb-Cu-Ag HEAs) have become ideal materials for solving these problems due to their low elastic modulus, high strength, corrosion resistance, and excellent antibacterial properties.

[0003] In the field of antibacterial joint prostheses, Ag-containing titanium-based high-entropy alloys significantly inhibit bacterial biofilm formation through the synergistic effect of the antibacterial activity of silver (Ag) and copper (Cu). Simultaneously, their elastic modulus is close to that of human bone, effectively reducing stress shielding effects. The preparation of Ag-containing titanium-based high-entropy alloy materials requires the mixing of raw materials such as titanium, zirconium, niobium, copper, and silver in specific proportions.

[0004] Chinese utility model patent CN218393363U discloses a mixing device. Through the cooperation of sliding rods, movable sleeves, stirring rollers, vertical plates, and mixing boxes, a motor can be controlled to drive two sliding rods to rotate inside the mixing box. At the same time, several stirring rollers on the movable sleeves agitate the materials. Then, the mixing box is rotated so that the box cover faces downwards. At this time, the materials inside the mixing box fall onto the box cover under the action of gravity. Simultaneously, the movable sleeves on the two sliding rods slide to the horizontal plate under the action of gravity. By changing the direction of the opening of the mixing box, the two sliding rods inside can achieve the purpose of forward or reverse rotation, thereby achieving a better mixing effect. At the same time, when the opening of the mixing box faces downwards, it is convenient to discharge the materials inside.

[0005] Since high-entropy alloys are composed of multiple metallic elements with equal or near-equal atomic ratios, each element needs to be uniformly distributed at the microscale to form a stable single-phase solid solution structure. This mixing equipment uses a traditional mixing method with stirring rollers, which mainly relies on the shear force, convection and diffusion generated by mechanical stirring to mix different particles at the macroscale. It cannot apply enough energy to the particles to overcome the interaction forces between them, which easily leads to uneven distribution of elements in some areas, affecting the formation of a stable high-entropy alloy structure in the subsequent preparation. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides a processing device for Ag-based high-entropy alloy antibacterial materials.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a processing device for Ag-containing titanium-based high-entropy alloy antibacterial materials, comprising: a base, a plurality of fixed plates fixed to the top of the base, and a processing tank hinged between the plurality of fixed plates;

[0008] The processing tank has a support plate fixed to its side for supporting the processing tank when it is in a horizontal position. A top cover is installed at one end of the processing tank. A grinding processing assembly is installed inside the processing tank.

[0009] The grinding assembly includes: a rotating rod disposed inside the processing tank, a grinding roller fixed to the side of the rotating rod, and a plurality of grinding teeth fixed to the inner wall of the processing tank; the grinding roller meshes with the plurality of grinding teeth, and a power mechanism for driving the rotating rod to rotate circumferentially along the inner wall of the processing tank is installed on the inner side of the top cover.

[0010] In a preferred embodiment of this utility model, the power mechanism includes: a servo motor fixed to one side of the top cover, a drive gear mounted on the output shaft of the servo motor located inside the top cover, and an internal gear fixed to the inside of the top cover; a driven gear meshes between the drive gear and the internal gear, the inner side of the driven gear is fixed to the side of the rotating rod, and a limit member is provided between the output shaft of the servo motor and the rotating rod.

[0011] In a preferred embodiment of the present invention, the limiting member includes: a limiting plate fixed to the side of the output shaft of the servo motor; one end of the limiting plate is rotatably connected to one end of the rotating rod.

[0012] In a preferred embodiment of the present invention, a circular limiting groove is provided at the bottom of the processing tank, and a limiting roller is rotatably connected to one end of the rotating rod facing the circular limiting groove, with the bottom end of the limiting roller located inside the circular limiting groove.

[0014] In a preferred embodiment of this utility model, valves are installed on the sides of both the feed cylinder and the discharge cylinder.

[0015] In a preferred embodiment of this utility model, one side of the top cover is connected to the top of the processing tank via a flange for easy disassembly and installation.

[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0020] (1) This utility model provides a processing device for antibacterial materials containing Ag titanium-based high-entropy alloys. By setting a grinding processing component inside the processing tank, the raw materials to be mixed are placed inside the processing tank. Through the cooperation of the power mechanism, rotating rod, grinding roller and several grinding teeth, grinding and mixing processing can be achieved.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] like Figure 1 and Figure 2 As shown, a processing device for an Ag-based high-entropy alloy antibacterial material includes: a base 1, several fixed plates 11 fixed to the top of the base 1, and a processing tank 12 hinged between the several fixed plates 11.

[0032] The processing tank 12 is fixed with a support plate 13 for supporting the processing tank 12 when it is in a horizontal position. A top cover 14 is installed at one end of the processing tank 12. A grinding processing assembly is installed inside the processing tank 12.

[0033] The grinding assembly includes: a rotating rod 2 disposed inside the processing tank 12, a grinding roller 21 fixed to the side of the rotating rod 2, and a plurality of grinding teeth 22 fixed to the inner wall of the processing tank 12; the grinding roller 21 meshes with the plurality of grinding teeth 22, and a power mechanism for driving the rotating rod 2 to rotate circumferentially along the inner wall of the processing tank 12 is installed on the inner side of the top cover 14.

[0034] It should be noted that a number of grinding teeth 22 are evenly distributed circumferentially on the inner wall of the processing tank 12, and the meshing gap between the grinding roller 21 and the grinding teeth 22 is 0.1-0.3mm.

[0035] Specifically, after placing the raw materials to be mixed (such as titanium, zirconium, niobium, copper, and silver) inside the processing tank 12, the processing tank 12 is rotated around the hinge points between several fixed plates 11, so that the processing tank 12 is in a horizontal state relative to the base 1 and is supported by the support plate 13. The power mechanism drives the rotating rod 2 to rotate circumferentially along the inner wall of the processing tank 12. At the same time, it can drive the grinding roller 21 fixed on the side of the rotating rod 2 to rotate together. Since the grinding roller 21 meshes with several grinding teeth 22 on the inner wall of the processing tank 12, the material is subjected to extrusion, friction, and agitation between the grinding roller 21 and the grinding teeth 22, which can achieve grinding and mixing. In addition, by using grinding and mixing, the metal powder is driven by mechanical force to repeatedly collide, rub, and plastically deform, effectively breaking up particle aggregation. It can achieve uniform distribution of raw materials at a smaller scale, thereby avoiding the local element segregation that is easy to cause by traditional stirring and mixing methods. This ensures that the subsequent preparation of high-entropy alloys forms a stable single-phase solid solution structure, thereby improving the overall performance consistency of the material.

[0036] like Figure 3 and Figure 4 As shown, in some embodiments, the power mechanism includes: a servo motor 3 fixed to one side of the top cover 14, a drive gear 31 mounted on the output shaft of the servo motor 3 located inside the top cover 14, and an internal gear 32 fixed inside the top cover 14; a driven gear 33 meshes between the drive gear 31 and the internal gear 32, the inner side of the driven gear 33 is fixed to the side of the rotating rod 2, and a limit member is provided between the output shaft of the servo motor 3 and the rotating rod 2.

[0037] Specifically, after the servo motor 3 is started, its output shaft drives the drive gear 31 to rotate. Since the drive gear 31 and the inner gear 32 are meshed with a driven gear 33, the rotation of the drive gear 31 will drive the driven gear 33 to rotate around the inner gear 32. And through the inner side of the driven gear 33 and the side of the rotating rod 2, the rotation of the driven gear 33 will drive the rotating rod 2 to rotate together, thereby providing power to the grinding roller 21 and making it rotate circumferentially along the inner wall of the processing tank 12.

[0038] In some embodiments, the limiting component includes: a limiting plate 4 fixed to the side of the output shaft of the servo motor 3; one end of the limiting plate 4 is rotatably connected to one end of the rotating rod 2.

[0039] Specifically, by setting the limiting plate 4, since the limiting plate 4 is fixed on the side of the output shaft of the servo motor 3, and one end of the limiting plate 4 is rotatably connected to one end of the rotating rod 2, the relative position between the output shaft of the servo motor 3 and the rotating rod 2 can be kept stable, so that the power can be stably transmitted to the rotating rod 2.

[0040] like Figure 2 and Figure 3As shown, in some embodiments, a circular limiting groove 5 is provided at the bottom of the processing tank 12, and a limiting roller 51 is rotatably connected to one end of the rotating rod 2 facing the circular limiting groove 5. The bottom end of the limiting roller 51 is located inside the circular limiting groove 5.

[0041] It should be noted that the side of the limiting roller 51 is rotatably connected to one end of the rotating rod 2 via a bearing, and the bottom surface of the limiting roller 51 is in contact with the inner side of the circular limiting groove 5.

[0042] Specifically, when the rotating rod 2 rotates, the limiting roller 51 rolls in the circular limiting groove 5. The circular limiting groove 5 provides a track for the limiting roller 51, restricting the movement of the rotating rod 2 in the radial and axial directions, ensuring the stability of the rotating rod 2 during rotation, and preventing the rotating rod 2 from shaking or deviating due to uneven force, thereby ensuring the normal and stable operation of the grinding and mixing process.

[0043] In some embodiments, a feed cylinder 6 is fixed to one side of the top cover 14, and the inner side of the feed cylinder 6 extends to the inner side of the top cover 14. A discharge cylinder 61 is fixed to the bottom of the processing tank 12, and the inner side of the discharge cylinder 61 extends to the inner side of the processing tank 12.

[0044] Specifically, the feed cylinder 6 extends from the inside to the inside of the top cover 14. During feeding, the processing tank 12 is adjusted to be perpendicular to the base 1 to facilitate the addition of raw materials containing Ag-based titanium high-entropy alloy antibacterial materials into the processing tank 12. The discharge cylinder 61 extends from the inside to the inside of the processing tank 12. After the mixing process is completed, the processing tank 12 is adjusted to be perpendicular to the base 1 to discharge the ground material from the processing tank 12.

[0045] In some embodiments, valves are installed on the sides of both the feed cylinder 6 and the discharge cylinder 61; the valves can be used to control the opening and closing of the feed cylinder 6 and the discharge cylinder 61, and the valves of the feed cylinder 6 and the discharge cylinder 61 can be closed during the grinding process to prevent material leakage.

[0046] In some embodiments, one side of the top cover 14 is connected to the top of the processing tank 12 via a flange for easy disassembly and installation.

[0047] Specifically, the top cover 14 is connected to the top of the processing tank 12 via a flange on one side. When it is necessary to inspect or clean the grinding components inside the processing tank 12, the flange can be removed to separate the top cover 14 from the processing tank 12, making it easier for operators to perform relevant operations inside the processing tank 12.

[0048] like Figure 5As shown, in some embodiments, the top of the base 1 is provided with a slot 7, the bottom of the support plate 13 is fixed with a card plate 71, the side of the card plate 71 is inserted into the inside of the slot 7, and one side of the card plate 71 is provided with a chamfer structure.

[0049] Specifically, when the processing tank 12 is in a horizontal position, the retaining plate 71 at the bottom of the support plate 13 is inserted into the retaining groove 7 at the top of the base 1. The cooperation between the retaining groove 7 and the retaining plate 71 restricts the horizontal movement of the support plate 13, thereby ensuring the stability of the processing tank 12 in a horizontal state. The chamfered structure serves as a guide when the retaining plate 71 is inserted into the retaining groove 7, making it easier to insert the retaining plate 71 into the retaining groove 7 and improving the convenience of installation.

[0050] like Figure 1 As shown, in some embodiments, a handle 8 is fixed to the side of the processing tank 12 for easy operation by workers to pull the processing tank 12 to flip it over.

[0051] Specifically, the handle 8 fixed to the side of the processing tank 12 makes it easy for workers to pull the processing tank 12 to flip it. When it is necessary to change raw materials, clean the processing tank 12, or perform other operations, workers can apply external force by holding the handle 8 to make the processing tank 12 flip around the hinge axis, thereby facilitating the relevant operations.

[0052] In some embodiments, the surface of the base 1 is provided with a plurality of mounting holes 9.

[0053] Specifically, the base 1 has several mounting holes 9 on its surface, which are used to fix the entire processing device to the worktable or other fixed foundation. By installing bolts or other fasteners in the mounting holes 9, the base 1 can be firmly fixed, preventing the device from moving or shaking during operation and ensuring the stability and processing accuracy of the device.

[0054] In use, the raw materials to be mixed, such as titanium, zirconium, niobium, copper, and silver, are first added to the processing tank 12 through the feed cylinder 6 (at this time, the processing tank 12 is perpendicular to the base 1, and the valve of the feed cylinder 6 is open). After the feeding is completed, the valve of the feed cylinder 6 is closed. Then, the operator holds the handle 8 on the side of the processing tank 12 and pulls the processing tank 12 to rotate around the hinge point between the fixed plates 11, so that it is in a horizontal state relative to the base 1. At this time, the retaining plate 71 at the bottom of the support plate 13 is inserted into the retaining groove 7 at the top of the base 1. The chamfered structure plays a guiding role. The retaining groove 7 and the retaining plate 71 cooperate to restrict the horizontal movement of the support plate 13, ensuring the horizontal stability of the processing tank 12. The servo motor 3 is started, and its output shaft drives the drive gear 31 to rotate. The drive gear 31 drives the driven gear 33, which meshes with the internal gear 32, to rotate around the internal gear 32. Since the inner side of the driven gear 33 is fixed to the side of the rotating rod 2, the rotating rod 2 is driven to rotate circumferentially along the inner wall of the processing tank 12. The rotating rod 2 drives the grinding roller 21, which is fixed to its side, to rotate together. The grinding roller 21 interacts with the grinding teeth 22 on the inner wall of the processing tank 12. The material is subjected to squeezing, friction, and agitation between the two, achieving grinding and mixing processing, effectively breaking up particle agglomeration, achieving uniform distribution of raw materials at a smaller scale, avoiding local element segregation, ensuring the formation of a stable single-phase solid solution structure for the subsequent preparation of high-entropy alloys, and improving the overall performance consistency of the material. During the rotation of the rotating rod 2, the limiting roller 51 is rotatably connected to one end of the rotating rod 2 through a bearing. Its bottom end rolls in the circular limiting groove 5. The circular limiting groove 5 provides a motion track for the limiting roller 51, restricting the radial and axial movement of the rotating rod 2 and ensuring the rotational stability of the rotating rod 2. Meanwhile, the limiting plate 4 is fixed to the side of the output shaft of the servo motor 3 and one end is rotatably connected to one end of the rotating rod 2, ensuring the relative position of the output shaft of the servo motor 3 and the rotating rod 2 is stable, thus ensuring stable power transmission. After the mixing process is completed, the processing tank 12 is flipped over again to be perpendicular to the base 1, and the valve of the discharge cylinder 61 is opened to discharge the ground material. The top cover 14 is connected to the processing tank 12 by a flange, which facilitates disassembly and installation, and makes it easy to inspect the grinding components or clean the processing tank 12. The mounting holes 9 on the surface of the base 1 can be used to fix the device to the workbench or other fixed foundation with fasteners such as mounting bolts to prevent movement or shaking during operation, ensuring the stability and processing accuracy of the device. It is easy to operate, small in size, and suitable for rapid mixing of raw materials in the laboratory.
