Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically to a mixing device for producing zirconia ceramic block dye. Background Technology

[0002] With the continuous advancement of dental restoration technology, zirconia ceramic blocks are increasingly widely used in dental restorations, such as crowns and bridges. Zirconia ceramic blocks have advantages such as good mechanical properties, biocompatibility, and aesthetics, making them highly favored by the market. Staining agents play a key role in giving zirconia ceramic blocks the ideal color, enabling them to better match the color of the patient's natural teeth and improve the restoration effect. In order to meet diverse clinical needs, the types of zirconia ceramic block staining agents are constantly being enriched, and the corresponding production scale is also gradually expanding.

[0003] An existing mixing device for producing zirconia ceramic block dyes achieves the mixing effect of raw materials by rotating the stirring shaft. The device has a relatively simple structure, making the manufacturing process of the entire mixing device easy to control, and the installation and commissioning process is also relatively simple. Furthermore, the overall complexity of the equipment is reduced, making it easier for maintenance personnel to quickly locate and solve problems.

[0004] However, in actual use, the existing mixing device for producing zirconia ceramic block dyes relies on the simple rotation of the stirring shaft, which makes it difficult to completely eliminate the mixing dead corners. This causes the raw materials to easily accumulate in the dead corners, making it impossible to mix them fully with the raw materials in other areas. Consequently, it affects the overall mixing uniformity of the dye, resulting in local color deviations or uneven composition of the dye, which is not conducive to the stable control of product quality. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a mixing device for producing zirconia ceramic block dyes, which effectively solves the problem of dead zones in the mixing of raw materials in existing technologies, where raw materials tend to accumulate in dead zones, resulting in poor mixing effects and causing local color deviations or uneven composition of the dyes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

One set of limiting balls is movably connected to a support frame, and the other set of limiting balls is movably installed at the top of the mixing tank. A stirring blade is located at the end of the stirring rod away from the drive motor. A discharge pipe is located at the bottom of the mixing tank, and a transmission assembly is located below the drive motor. A rotating assembly is fixedly connected to the transmission assembly.

[0008] Furthermore, the drive motor is fixedly mounted on the support frame, the support frame is fixedly mounted on the top of the mixing tank, and a limiting groove is formed on the surface of the support frame near the mixing tank, the limiting groove and the limiting ball are slidably connected.

[0009] Furthermore, the stirring rod passes through the limiting ball and the feeding port, and the stirring rod is fixedly connected to the limiting ball and the feeding port.

[0010] Furthermore, the transmission assembly includes a first transmission wheel, which is driven by a belt, and the belt is driven by a second transmission wheel.

[0011] Furthermore, the rotating mechanism includes a rotating shaft fixedly mounted on the second transmission wheel, a connecting shaft fixedly connected to the end of the rotating shaft away from the second transmission wheel, a spur gear fixedly connected to the connecting shaft, and a helical gear meshing with the spur gear.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] I. This utility model drives the first transmission wheel to rotate by a drive motor, and utilizes the synergistic effect of the transmission component and the rotating component to realize the complex movement of the stirring rod and stirring blade in the mixing tank. This movement mode not only includes the circumferential rotation of the stirring rod around the output shaft of the drive motor, but also enables the stirring rod to rotate simultaneously through the action of the rotating component, which greatly improves the stirring efficiency, reduces the stirring dead angle, and further improves the mixing uniformity.

[0018] Second, by setting two sets of limiting balls, this utility model not only ensures the stable rotation of the stirring rod, but also limits its range of motion, avoiding raw material splashing or equipment damage caused by excessive stirring, thereby ensuring the stability and safety of the entire stirring process.

[0019] Third, this utility model, by covering the surface of the mixing tank with a tank body and installing a temperature controller and heater on its outer wall, can ensure that the temperature of the mixing tank and the dye inside it remains constant through precise monitoring and adjustment of the temperature controller.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] A mixing apparatus for producing zirconia ceramic block dye, see attached. Figures 1-5The system includes a mixing tank 5, with a feeding port 22 at the top. A drive motor 8 is positioned above the feeding port 22, and a first transmission wheel 11 is located at the output end of the drive motor 8. A bushing 18 is fixedly connected to the first transmission wheel 11, and a stirring rod 19 is rotatably connected to the bushing 18. Two sets of limiting balls 20 are fitted onto the surface of the stirring rod 19. One set of limiting balls 20 is movably connected to a support frame 9, and the other set of limiting balls 20 is movably mounted at the top of the mixing tank 5. The drive motor 8 is fixedly mounted on the support frame 9, which is also fixedly mounted at the top of the mixing tank 5. A limiting groove 24 is formed on the surface of the support frame 9 near the mixing tank 5, and the limiting groove 24 is slidably connected to the limiting balls 20. The stirring rod 19 passes through the limiting balls 20 and the feeding port 22, and is fixedly connected to the limiting balls 20 and the feeding port 22. A [missing information - likely a design feature] is provided at the end of the stirring rod 19 furthest from the drive motor 8. The mixing tank 5 is equipped with stirring blades 26 and a discharge pipe 2 at the bottom. Raw materials are added to the mixing tank 5 through the feeding port 22. The drive motor 8, in the open state, drives the first transmission wheel 11 to rotate through the output shaft. The first transmission wheel 11 drives the bushing 18 to rotate. A set of limiting balls 20 away from the mixing tank 5 rotates the stirring rod 19 in the limiting groove 24 opened on the support frame 9. A set of limiting balls close to the mixing tank 5 plays a bearing role, ensuring that the stirring rod 19 rotates stably in a circular motion with the center of the first transmission wheel as the origin. This allows the stirring blades 26 installed on the stirring rod 19 to effectively mix and stir the raw materials, effectively eliminating the mixing dead corners, thereby improving the mixing uniformity of the raw materials and ensuring the stable quality of the dye product. After the raw materials are completely mixed, the seal on the discharge pipe 2 is released, allowing the product to flow out smoothly from the discharge pipe 2.

[0030] Furthermore, a transmission assembly is provided below the drive motor 8. The transmission assembly includes a first transmission wheel 11, which is connected to a belt 12. The belt 12 is connected to a second transmission wheel 13. The rotation of the first transmission wheel 11 drives the second transmission wheel 13 to rotate through the belt 12, thereby causing the stirring rod 19 to rotate and driving the rotating assembly to rotate, effectively improving the efficiency of raw material mixing.

[0031] Furthermore, the transmission assembly is fixedly connected to a rotating assembly. The rotating mechanism includes a rotating shaft 14 fixedly mounted on the second transmission wheel 13. A connecting shaft 15 is fixedly connected to one end of the rotating shaft 14 away from the second transmission wheel 13. A spur gear 16 is fixedly connected to the connecting shaft 15. The spur gear 16 meshes with a helical gear 21. The rotating shaft 14 passes through the support frame 9 and is rotatably connected to the support frame 9. The helical gear 21 is sleeved on the surface of the stirring rod 19. The rotation of the second transmission wheel 13 drives the spur gear 16 to rotate through the transmission between the rotating shaft 14 and the connecting shaft 15. The spur gear 16 drives the helical gear 21 to rotate through meshing, thereby causing the stirring rod 19 to rotate. This achieves the simultaneous circumferential rotation and rotation of the stirring blade 26, thereby further improving the mixing effect.

[0032] The mixing tank 5 has a discharge port 6 at the bottom, which is connected to the discharge pipe 2. The mixing tank 5 is also equipped with a support leg 3 at the bottom. The discharge port 6 and the discharge pipe 2 ensure that the equipment can maintain a good working condition after long-term operation. The support leg 3 provides stable support for the mixing tank 5, ensuring that the equipment will not shake or tilt during operation, thereby ensuring the stability and safety of the mixing process.

[0033] In addition, a barrel body 1 is fitted onto the surface of the mixing barrel 5, and a temperature controller 4 is installed on the outer wall of the barrel body 1. The temperature controller 4 is electrically connected to a heater 7. A cavity 27 is provided between the barrel body 1 and the mixing barrel 5. The temperature controller 4 can accurately monitor and adjust the temperature of the mixing barrel 5 and the dye inside it. The cavity 27 acts as a heat insulation layer, which helps to reduce heat loss and maintain the stability of the internal temperature of the mixing barrel 5. This not only saves energy but also ensures the temperature consistency of the dye during mixing and storage, thereby further improving product quality.

[0034] Working principle: During use, the drive motor 8 drives the first transmission wheel 11 to rotate, which in turn drives the second transmission wheel 13 and the connected rotating assembly to rotate via the belt 12. This causes the stirring rod 19 and the stirring blade 26 to rotate in a circular motion within the mixing tank 5 while simultaneously rotating on their own axis, effectively mixing the raw materials and eliminating dead zones in the mixing process. At the same time, the temperature controller 4 monitors and adjusts the temperature of the mixing tank 5 and the dye inside it. The heater 7 maintains a stable temperature, ensuring the consistency of the dye's quality during mixing and storage. Finally, the mixed dye is discharged through the discharge pipe 2.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
