Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical devices for ceramic material production, specifically a mechanical device for accurately weighing and mixing multiple raw materials. Background Technology

[0002] The raw materials for ceramic materials production are mostly in powder or granular form, with common raw materials including kaolin, quartz powder, pre-fired bone ash granules, and wollastonite granules. The production process of ceramic materials requires mechanical devices for the precise weighing and mixing of multiple raw materials. This is a type of weighing mixer specifically designed for the precise proportioning and mixing of various raw materials in industrial settings. Its core function is to achieve automated feeding and mixing of preset formulas through high-precision weighing sensors, intelligent control systems, and mixing technology.

[0003] When using a mechanical device for precise weighing and mixing of multiple raw materials, multiple raw materials are fed into the feeding hopper, and the weight of the raw materials is monitored in real time by a weighing sensor. When the weight reaches the preset value of the controller, the solenoid valve is opened, and the raw materials are discharged into the mixing tank. The mixing mechanism in the mixing tank mixes the multiple raw materials. During the feeding process, the raw materials in a single feeding hopper will fall in a concentrated manner, causing the raw materials to accumulate in the mixing tank, making it difficult to disperse them quickly and evenly, thus affecting the mixing effect and efficiency. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a mechanical device for accurately weighing and mixing multiple raw materials, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical device for precise weighing and mixing of multiple raw materials, including a mixing tank, a feeding hopper is provided at the top of the mixing tank at equal angles, a support plate is connected to the outside of the feeding hopper, and a weighing sensor is installed between the support plate and the mixing tank, an electromagnetic valve is provided at the bottom of the feeding hopper, and a mixing mechanism is provided through the interior of the mixing tank, the mixing mechanism including a stirring shaft connected to the mixing tank through a bearing;

[0006] A dispersing plate A is movably connected to the inner side of the mixing tank. Dispersing holes are uniformly opened inside the dispersing plate A. A dispersing mechanism is provided between the dispersing plate A and the mixing tank. The dispersing mechanism includes a support shaft connected to the mixing tank through a bearing. A pulley assembly is connected between the support shaft and the stirring shaft. A toothed disc is sleeved on the outer surface of the support shaft. An internal toothed ring is meshed with the outer side of the toothed disc. A dispersing plate B is provided at the top of the inner side of the mixing tank. A spiral component is sleeved on the outer surface of the stirring shaft near the end of the dispersing plate A.

[0007] Preferably, the top of the dispersion plate A is provided with a support rod welded to the internal gear ring at an equal angle, and the top of the inside of the mixing tank is provided with a support groove that forms a sliding structure with the support rod.

[0008] Preferably, the dispersion plate A is configured as a funnel-shaped structure.

[0009] Preferably, the dispersing plate B includes an inclined plate, a vertical rod located between the inclined plate and the mixing tank, and a dispersing rod located at the bottom end of the inclined plate, and the dispersing plate B is symmetrically arranged about the central axis of the stirring shaft.

[0010] Preferably, a drive motor connected to the stirring shaft via a coupling is installed at the top of the mixing tank, and stirring rods are provided at equal angles on the outer side of the stirring shaft.

[0011] Preferably, the bottom of the mixing tank is provided with a discharge hopper, and the top of the mixing tank is provided with a feed inlet at an equal angle that matches the feed hopper.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention features a funnel-shaped dispersion plate A, which, in conjunction with dispersion holes, initially disperses the falling raw materials, preventing them from accumulating. When the stirring shaft rotates, the pulley system causes the support shaft and gear disc to rotate. Since the gear disc meshes with the inner gear ring, and the inner gear ring is slidably connected to the mixing tank via a support rod and support groove, the inner gear ring and dispersion plate A rotate together, thereby improving the dispersion effect and efficiency of the raw materials. This also prevents the dispersion holes of dispersion plate A from becoming clogged. Furthermore, a fixed dispersion plate B further disperses the raw materials on dispersion plate A during movement, further improving the dispersion effect and efficiency. A spiral component on the surface of the stirring shaft facilitates the downward conveying of raw materials sliding down dispersion plate A, preventing accumulation between the stirring shaft and dispersion plate A and ensuring efficient material feeding. Moreover, the above operations are driven solely by the mixing mechanism's drive motor, eliminating the need for additional drive equipment and reducing energy consumption.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] A mechanical device for precise weighing and mixing of multiple raw materials, such as Figure 1 and Figure 5 As shown, the system includes a mixing tank 1, a feeding hopper 3 at an equal angle at the top of the mixing tank 1, a discharge hopper 2 at the bottom of the mixing tank 1, a feeding port at an equal angle at the top of the mixing tank 1 that matches the feeding hopper 3, a support plate 5 connected to the outside of the feeding hopper 3, and a weighing sensor 6 installed between the support plate 5 and the mixing tank 1, a solenoid valve 7 installed at the bottom of the feeding hopper 3, and a mixing mechanism 4 for uniformly mixing raw materials for ceramic material production installed through the interior of the mixing tank 1. The mixing mechanism 4 includes a stirring shaft 402 connected to the mixing tank 1 via a bearing, a drive motor 401 connected to the stirring shaft 402 via a coupling installed at the top of the mixing tank 1, and a stirring rod 403 at an equal angle on the outside of the stirring shaft 402.

[0023] See Figure 1 and Figure 5 As can be seen, raw materials are put into the feed hopper 3, and the weight of the raw materials is monitored in real time by the weighing sensor 6. When the weight reaches the preset value of the controller, the solenoid valve 7 is opened, allowing the raw materials to be discharged into the mixing tank. At the same time, the drive motor 401 is driven. The output end of the drive motor 401 drives the stirring shaft 402 and the stirring rod 403 to rotate. Through the cooperation of the stirring shaft 402 and the stirring rod 403, the precise weighing of multiple raw materials is mixed.

[0024] See Figures 1-3It is known that a dispersing plate A8 is movably connected to the inner side of the mixing tank 1. Dispersing holes 12 are evenly opened inside the dispersing plate A8. The dispersing plate A8 is set as a funnel-shaped structure. By setting the dispersing plate A8 as a funnel-shaped structure and cooperating with the dispersing holes 12 to initially disperse the falling raw materials, the concentrated accumulation of raw materials in ceramic material production can be avoided, which will affect the mixing effect and efficiency.

[0025] See Figures 1-4 It is known that a dispersion mechanism 9 is provided between the dispersion plate A8 and the mixing tank 1. The dispersion mechanism 9 includes a support shaft 902 connected to the mixing tank 1 via a bearing. A pulley group 901 for driving the support shaft 902 to rotate is connected between the support shaft 902 and the stirring shaft 402. A toothed disc 903 is sleeved on the outer surface of the support shaft 902. An inner toothed ring 904 is meshed with the outer side of the toothed disc 903.

[0026] See Figures 1-4 It can be seen that when the stirring shaft 402 rotates, the support shaft 902 and the gear disk 903 rotate through the linkage of the pulley group 901. Since the gear disk 903 meshes with the inner gear ring 904, and the inner gear ring 904 is slidably connected to the mixing tank 1 through the support rod 905 and the support groove 906, the inner gear ring 904 and the dispersing plate A8 rotate together, thereby improving the dispersion effect and efficiency of the raw materials, and at the same time preventing the dispersing holes 12 of the dispersing plate A8 from being blocked.

[0027] See Figure 1 , Figure 3 and Figure 4 It is known that a spiral component 10 is sleeved on the outer surface of the stirring shaft 402 near the dispersing plate A8. By providing the spiral component 10 on the surface of the stirring shaft 402, it is beneficial to convey the raw materials sliding down the dispersing plate A8 downwards, thereby preventing the raw materials from accumulating between the stirring shaft 402 and the dispersing plate A8 and causing the gap between the stirring shaft 402 and the dispersing plate A8 to be blocked, so as to ensure the feeding effect.

[0028] See Figure 2 and Figure 3 It is known that the top of the dispersing plate A8 is provided with a support rod 905 welded to the internal gear ring 904 at an equal angle. The top of the inside of the mixing tank 1 is provided with a support groove 906 that forms a sliding structure with the support rod 905. This groove can support and guide the internal gear ring 904 and the dispersing plate A8, so that the internal gear ring 904 and the dispersing plate A8 can rotate stably.

[0029] See Figures 1-3It is known that a dispersing plate B11 is provided at the top of the inner side of the mixing tank 1. The dispersing plate B11 includes an inclined plate, a vertical rod located between the inclined plate and the mixing tank 1, and a dispersing rod located at the bottom of the inclined plate. The dispersing plate B11 is symmetrically arranged about the central axis of the stirring shaft 402. The raw materials on the dispersing plate A8 during the movement are further dispersed by the fixedly arranged dispersing plate B11, thereby further improving the dispersion effect and efficiency of the raw materials.

[0030] The working principle of this utility model is as follows: When using this utility model, raw materials are put into the feeding hopper 3, and the weight of the raw materials is monitored in real time by the weighing sensor 6. When the weight reaches the preset value of the controller, the solenoid valve 7 is opened, allowing the raw materials to be discharged into the mixing tank. The mixing mechanism 4 in the mixing tank then mixes the accurately weighed raw materials. During the feeding process, the funnel-shaped dispersing plate A8, together with the dispersing holes 12, initially disperses the falling raw materials to prevent them from accumulating. At the same time, the linkage of the pulley group 901 causes the support shaft 902 and the gear plate 903 to rotate. The meshing action of the gear plate 903 and the internal gear ring 904 causes the internal gear ring 904 to rotate. The mixing shaft 402 rotates together with the dispersing plate A8, thereby improving the dispersion effect and efficiency of the raw materials. In addition, the dispersing plate B11, which is fixedly set, can further disperse the raw materials on the dispersing plate A8 during the movement, further improving the dispersion effect and efficiency of the raw materials. At the same time, the spiral part 10 on the surface of the mixing shaft 402 helps to convey the raw materials sliding down the dispersing plate A8 downward, thereby preventing the raw materials from accumulating between the mixing shaft 402 and the dispersing plate A8 and causing blockage of the gap between the mixing shaft 402 and the dispersing plate A8. The uniformly mixed raw materials are discharged through the discharge hopper 2. The contents not described in detail in this description are the prior art known to those skilled in the art.
