Description

Technical Field

[0001] This utility model relates to the field of zirconia processing technology, specifically to a zirconia slurry mixing device. Background Technology

[0002] Zirconia slurry molding refers to the process of adding an appropriate amount of water or organic liquid and a small amount of electrolyte to zirconia powder to form a relatively stable suspension. The suspension is then injected into a plaster mold to absorb the water, thus achieving the molding purpose. Zirconia slurry can be used to manufacture commonly used products such as artificial teeth.

[0003] When mixing zirconia slurry, the added zirconia raw materials often clump together. Existing zirconia slurry mixing devices are generally not suitable for crushing these materials, making it difficult to fully mix the zirconia raw materials with other ingredients. At the same time, traditional stirring mechanisms cannot thoroughly agitate the slurry, further reducing the production efficiency of zirconia slurry. Based on this, this solution provides a zirconia slurry mixing device to address the aforementioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a zirconia slurry mixing device is provided, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A zirconia slurry mixing device includes a mixing tank and a tank cover fixedly mounted on the mixing tank. A servo motor is fixedly mounted on the upper end of the tank cover, and the output shaft of the servo motor is fixedly connected to a stirring shaft. The lower end of the stirring shaft is rotatably connected to the bottom inner wall of the mixing tank. A guide plate is fixedly connected to the upper side of the inner wall of the mixing tank, and the guide plate is rotatably connected to the stirring shaft. A crushing mechanism for crushing raw materials is provided on the upper side of the guide plate. A first fixing frame is fixedly connected to the stirring shaft, and a second fixing frame is fixedly connected to the stirring shaft on the lower side of the first fixing frame. Several sets of stirring rods are fixedly connected to the stirring shaft between the first fixed frame and the second fixed frame. A stirring assembly is provided between the first fixed frame and the second fixed frame. The stirring assembly includes two sets of rotating rods rotatably mounted on the first fixed frame. The lower ends of the rotating rods are rotatably connected to the second fixed frame. Several sets of stirring rods are fixedly connected to each rotating rod. A transmission gear is fixedly connected to the upper end of each rotating rod. A fixed rod is fixedly connected to the guide plate on one side of the transmission gear. A fixed gear is fixedly installed at the lower end of the fixed rod. The transmission gear meshes with the fixed gear.

[0007] Preferably, two sets of rotating rods are symmetrically arranged on both sides of the first fixed frame about the center of the stirring shaft, and several sets of stirring rod one and several sets of stirring rod two are arranged alternately.

[0008] Preferably, scrapers are fixedly connected to both ends of the first fixing frame, and the lower end of the scraper is fixedly connected to one end of the second fixing frame. The scraper is used to clean the inner wall of the box cover.

[0009] Preferably, the guide plate is provided with an annular groove, and the bottom of the annular groove is provided with several sets of sieve holes.

[0010] Preferably, the crushing mechanism includes a fixed sleeve on the stirring shaft of the fixed connecting body, a cleaning component fixedly connected to the right side of the fixed sleeve, a fixed frame fixedly connected to the left side of the fixed sleeve, two sets of sliding rods slidably connected inside the fixed frame, a mounting frame fixedly connected to the lower end of the sliding rods, a pressure roller rotatably mounted inside the mounting frame, the lower end of the pressure roller abutting against the guide plate, a limit plate fixedly connected to the upper end of the sliding rods, a protruding plate fixedly connected to the sliding rods, and a spring fixedly connected between the protruding plate and the fixed frame, the spring being sleeved on the outside of the sliding rods.

[0011] Preferably, the cleaning component includes a horizontal plate fixedly connected to the fixed sleeve, a cleaning rod for cleaning the guide plate is provided on the lower side of the horizontal plate, and several sets of connecting rods are fixedly connected between the horizontal plate and the cleaning rod.

[0012] Preferably, the box cover has a feed inlet, and a feed funnel fixedly connected to the box cover is provided on the upper side of the feed inlet. The front end of the mixing box is provided with a discharge pipe, and a solenoid valve is fixedly installed on the discharge pipe.

[0013] Compared with the prior art, the present invention proposes a zirconium oxide slurry mixing device, which has the following beneficial effects:

[0014] 1. This utility model includes a crushing mechanism. Zirconia powder enters the mixing tank through a feed funnel and, guided by a guide plate, enters the annular groove. A servo motor then drives the stirring shaft, which in turn drives a fixed frame and a horizontal plate via a fixed sleeve. The fixed frame, through an internal sliding rod, drives a mounting frame on its lower side. The mounting frame then drives a pressure roller to rotate with the stirring shaft. Under the action of a spring, the pressure roller rolls on the zirconia powder, crushing any clumps and preventing the powder from becoming too large. The spring-driven pressure roller also has a certain degree of flexibility to prevent excessive pressure from damaging the guide plate. Simultaneously, the horizontal plate, through several sets of connecting rods, synchronously drives a cleaning rod to move on the guide plate. The cleaning rod scrapes up the powder adhering to the guide plate and pushes it to fall through the sieve holes, accelerating the screening efficiency. The crushing mechanism crushes the clumps of zirconia raw material, which then falls through the sieve holes into the mixing tank, allowing the zirconia powder to be fully mixed with other ingredients, thus improving the production efficiency of the zirconia slurry.

[0015] 2. This utility model includes a first stirring rod and a second stirring rod. When the servo motor drives the stirring shaft to rotate, the stirring shaft in turn drives the first stirring rod to stir the solution. Simultaneously, it drives the first and second fixed frames on the upper and lower sides of the first stirring rod to rotate. During the rotation of the first and second fixed frames, the rotating rods in the stirring components on both sides are driven. The upper end of the rotating rod is fixedly connected to a transmission gear, which meshes with the fixed gear. As the rotating rod rotates around the stirring shaft with the first and second fixed frames, the transmission gear drives the rotating rod to rotate on its own axis. This causes the second stirring rod to rotate around the stirring shaft and rotate on its own axis, thus cooperating with the first stirring rod to achieve thorough stirring of the solution and improve the production efficiency of zirconia slurry.

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figure 1-6 As shown, a zirconia slurry mixing device includes a mixing tank 1 and a tank cover 2 fixedly installed on the mixing tank 1. A servo motor 3 is fixedly installed on the upper end of the tank cover 2. The output shaft of the servo motor 3 is fixedly connected to a stirring shaft 6. The lower end of the stirring shaft 6 is rotatably connected to the bottom inner wall of the mixing tank 1. A guide plate 7 is fixedly connected to the upper side of the inner wall of the mixing tank 1. The guide plate 7 is rotatably connected to the stirring shaft 6. A crushing mechanism 8 for crushing raw materials is provided on the upper side of the guide plate 7. A first fixing frame 9 is fixedly connected to the stirring shaft 6. A second fixing frame 10 is fixedly connected to the stirring shaft 6 on the lower side of the first fixing frame 9. A plurality of sets of stirring rods 11 fixedly connected to the stirring shaft 6 are provided between the first fixing frame 9 and the second fixing frame 10. A stirring assembly 12 is provided between the first fixing frame 9 and the second fixing frame 10.

[0026] Furthermore: Zirconia powder enters the mixing tank 1 through the feed funnel 4 and, guided by the guide plate 7, enters the annular groove. Subsequently, the servo motor 3 drives the stirring shaft 6, which in turn drives the crushing mechanism 8. The crushing mechanism 8 quickly crushes the agglomerated zirconia powder to prevent the powder from being too large. The raw material powder is also screened through the sieve holes 701 on the guide plate 7 to prevent the powder entering the mixing tank 1 from being too large, so that the powder can be fully mixed with other ingredients. After entering the mixing tank 1, the stirring shaft 6 drives the stirring rod 11 to stir the solution. At the same time, it synchronously drives the first fixed frame 9 and the second fixed frame 10 on the upper and lower sides of the stirring rod 11 to rotate. During the rotation of the first fixed frame 9 and the second fixed frame 10, the stirring assembly 12 is driven synchronously. Through the cooperation between the stirring assembly 12 and the stirring rod 11, the solution is fully stirred, improving the production efficiency of zirconia slurry.

[0027] Specifically, in this embodiment, the stirring assembly 12 includes two sets of rotating rods 1201 rotatably mounted on the first fixed frame 9. The lower ends of the rotating rods 1201 are rotatably connected to the second fixed frame 10. Several sets of stirring rods 1202 are fixedly connected to each rotating rod 1201. A transmission gear 1203 is fixedly connected to the upper end of each rotating rod 1201. A fixed rod 1205 is fixedly connected to the guide plate 7 on one side of the transmission gear 1203. A fixed gear 1204 is fixedly mounted on the lower end of the fixed rod 1205. The transmission gear 1203 meshes with the fixed gear 1204.

[0028] Furthermore: When the servo motor 3 drives the stirring shaft 6 to rotate, the stirring shaft 6 in turn drives the stirring rod 11 to stir the solution. At the same time, it synchronously drives the first fixed frame 9 and the second fixed frame 10 on both sides of the stirring rod 11 to rotate. During the rotation of the first fixed frame 9 and the second fixed frame 10, the rotating rod 1201 in the stirring assembly 12 on both sides is driven. The upper end of the rotating rod 1201 is fixedly connected to the transmission gear 1203. The transmission gear 1203 meshes with the fixed gear 1204. As the rotating rod 1201 rotates around the stirring shaft 6 with the first fixed frame 9 and the second fixed frame 10, the transmission gear 1203 drives the rotating rod 1201 to rotate on its own axis. This causes the rotating rod 1201 to drive the stirring rod 1202 to rotate around the stirring shaft 6 and rotate on its own axis. Together with the stirring rod 11, this achieves full stirring of the solution and improves the production efficiency of the zirconia slurry.

[0029] Specifically, in this embodiment, two sets of rotating rods 1201 are symmetrically arranged on both sides of the first fixed frame 9 about the center of the stirring shaft 6, and several sets of stirring rod one 11 and several sets of stirring rod two 1202 are arranged alternately.

[0030] Specifically, in this embodiment, scrapers 13 are fixedly connected to both ends of the first fixing frame 9, and the lower end of the scraper 13 is fixedly connected to one end of the second fixing frame 10. The scraper 13 is used to clean the inner wall of the box cover 2.

[0031] When the servo motor 3 drives the stirring shaft 6 to rotate, the stirring shaft 6 in turn drives the stirring rod 11 to stir the solution. At the same time, it synchronously drives the first fixed frame 9 and the second fixed frame 10 on both sides of the stirring rod 11 to rotate, which in turn drives the scrapers 13 on both sides to rotate synchronously. The rotating scrapers 13 can scrape off the slurry adhering to the inner wall of the mixing tank 1, avoiding slurry waste and improving utilization.

[0032] Specifically, in this embodiment, the guide plate 7 is provided with an annular groove, and several sets of sieve holes 701 are opened through the bottom of the annular groove. The zirconia powder is screened through the sieve holes 701 to prevent the powder entering the mixing from being too large, so that the zirconia powder can be fully mixed with other ingredients, thereby improving the production efficiency of zirconia slurry.

[0033] Specifically, in this embodiment, the crushing mechanism 8 includes a fixed sleeve 801 fixedly connected to the stirring shaft 6. A cleaning component is fixedly connected to the right side of the fixed sleeve 801, and a fixed frame 802 is fixedly connected to the left side of the fixed sleeve 801. Two sets of sliding rods 803 are slidably connected inside the fixed frame 802. A mounting bracket 804 is fixedly connected to the lower end of the sliding rod 803. A pressure roller 805 is rotatably installed inside the mounting bracket 804. The lower end of the pressure roller 805 abuts against the guide plate 7. A limit plate 806 is fixedly connected to the upper end of the sliding rod 803. A protruding plate 807 is fixedly connected to the sliding rod 803, and a spring 808 is fixedly connected between the protruding plate 807 and the fixed frame 802. The spring 808 is sleeved on the outside of the sliding rod 803.

[0034] Furthermore: Zirconia powder enters the mixing tank 1 through the feed funnel 4 and, guided by the guide plate 7, enters the annular groove. Then, the servo motor 3 drives the stirring shaft 6, which in turn drives the fixed frame 802 and the horizontal plate 809 via the fixed sleeve 801. The fixed frame 802, through its internal sliding rod 803, drives the mounting frame 804 on its lower side. The mounting frame 804 then drives the pressure roller 805 to rotate with the stirring shaft 6. Under the action of the spring 808, the pressure roller 805 rolls on the zirconia powder, crushing any clumps and preventing the powder from becoming too large. The spring-driven pressure roller 805 also has a certain degree of flexibility to prevent excessive pressure from damaging the guide plate 7. The crushing mechanism 8 further crushes the clumps of zirconia raw material, which then falls through the sieve holes 701 into the mixing tank 1, allowing the zirconia powder to be fully mixed with other ingredients and improving the production efficiency of the zirconia slurry.

[0035] Specifically, in this embodiment, the cleaning component includes a horizontal plate 809 fixedly connected to the fixed sleeve 801. A cleaning rod 8011 for cleaning the guide plate 7 is provided on the lower side of the horizontal plate 809, and a number of connecting rods 8010 are fixedly connected between the horizontal plate 809 and the cleaning rod 8011.

[0036] Furthermore, at the same time, the horizontal plate 809 drives the cleaning rod 8011 to move on the guide plate 7 synchronously through several sets of connecting rods 8010. The cleaning rod 8011 can scrape up the powder adhering to the guide plate 7 and push the powder to move so that it can fall out of the sieve hole 701, thereby speeding up the screening efficiency.

[0037] Specifically, in this embodiment, the box cover 2 is provided with a feed inlet 201, and a feed funnel 4 is fixedly connected to the box cover 2 on the upper side of the feed inlet 201. The front end of the mixing box 1 is provided with a discharge pipe 5, and a solenoid valve is fixedly installed on the discharge pipe 5.

[0038] The working principle of this utility model is as follows: Zirconia powder enters the mixing tank 1 through the feed funnel 4, and under the guidance of the guide plate 7, it enters the annular groove. Then, the servo motor 3 drives the stirring shaft 6, which in turn drives the crushing mechanism 8 and the stirring mechanism on the lower side.

[0039] When the servo motor 3 drives the stirring shaft 6, the stirring shaft 6 in turn drives the fixed frame 802 and the horizontal plate 809 through the fixed sleeve 801. The fixed frame 802 drives the mounting frame 804 on the lower side through the internal sliding rod 803. The mounting frame 804 then drives the pressure roller 805 to rotate with the stirring shaft 6. Under the action of the spring 808, the pressure roller 805 rolls on the zirconium oxide powder, crushing the agglomerated zirconium oxide powder and preventing the powder from being too large. The pressure roller 805 driven by the spring 808 has a certain degree of flexibility to prevent excessive pressure from damaging the guide plate 7. At the same time, the horizontal plate 809 drives the cleaning rod 8011 to move on the guide plate 7 synchronously through several sets of connecting rods 8010. The cleaning rod 8011 can scrape up the powder adhering to the guide plate 7 and push the powder to move so that it can fall out of the sieve hole 701, thus speeding up the screening efficiency. The pulverizing mechanism 8 crushes the lumps of zirconia raw material and sends them through the sieve 701 into the mixing tank 1, so that the zirconia powder can be fully mixed with other ingredients, thereby improving the production efficiency of zirconia slurry.

[0040] Simultaneously, when the stirring shaft 6 rotates, it drives several sets of stirring rods 11 on its surface to stir the solution, and synchronously drives the first fixed frame 9 and the second fixed frame 10 on the upper and lower sides of the stirring rods 11 to rotate. During the rotation of the first fixed frame 9 and the second fixed frame 10, the rotating rods 1201 in the stirring assembly 12 on both sides are driven. The upper end of the rotating rod 1201 is fixedly connected to the transmission gear 1203. The transmission gear 1203 meshes with the fixed gear 1204, so that when the rotating rod 1201 rotates around the stirring shaft 6 with the first fixed frame 9 and the second fixed frame 10, the transmission gear 1203 drives the rotating rod 1201 to rotate on its own axis. Thus, the rotating rod 1201 drives the second stirring rod 1202 to rotate around the stirring shaft 6 and rotate on its own axis. In conjunction with the first stirring rod 11, the solution is fully stirred, and the production efficiency of the zirconia slurry is improved.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
