Description

Technical Field

[0001] This utility model relates to the technical field of diffusion plate production, and in particular to the technical field of a mixing device. Background Technology

[0002] A diffuser is a material that uses physical or chemical means to uniformly convert point or line light sources into surface light sources, or to uniformly distribute sound waves.

[0003] During the production process, the diffuser plate needs to mix the raw materials. In the existing diffuser plate mixing device, due to the effect of gravity sedimentation and the limitation of the bottom structure of the mixing device, it is difficult for the stirring blades to stir the raw materials at the bottom of the mixing device. Therefore, the raw materials at the bottom of the mixing device are prone to insufficient stirring, resulting in uneven mixing.

[0004] To address the problems mentioned above, for example, application number CN201921874672.X discloses a raw material mixer for diffusion plate production, including a mixing tank. A first motor is fixed at the top center of the mixing tank, and a stirring rod is connected below the first motor. The stirring rod is located inside the mixing tank, and stirring blades are evenly distributed around its outer periphery. Since a vibrating plate is installed inside the mixing tank, and a drive mechanism for controlling the up-and-down movement of the vibrating plate is installed on the outer side of the upper end of the pull rod, the second motor of the drive mechanism drives the pull rod and the vibrating plate to move up and down in a cyclical motion via a cam. The vibrating plate continuously stirs the raw material at the bottom, and works in conjunction with the stirring blades of the stirring rod to prevent insufficient stirring of the raw material at the bottom, so that the raw material in the mixing tank can be fully stirred and the raw material can be mixed evenly. The through-hole design on the vibrating plate ensures that the vibrating plate can stir the raw material at the bottom and also allows the raw material in the mixing tank to be discharged normally.

[0005] For example, application number CN202022375702.1 discloses a raw material mixing device for diffusion plate production, including a base. Support columns are fixedly installed on both sides of the top of the base. Support blocks are fixedly installed on the side of the two support columns that are close to each other. A mixing box with a hollow structure is fixedly installed at the end of the two support blocks that are close to each other. A discharge port is opened at the bottom of the mixing box, and a rotating hole is opened at the top of the mixing box. A rotating column is rotatably installed in the rotating hole. A stirring rod is fixedly installed on the outside of the rotating column. Mixing rods are fixedly installed on the top and bottom of the stirring rod. The material is fed through a feeding hopper. Then, a rotary motor is started. The output shaft of the rotary motor drives the rotating column to rotate. The rotating column drives multiple stirring rods to rotate. The multiple stirring rods drive multiple mixing rods to rotate. The multiple mixing rods mix the material in the mixing box evenly, resulting in a good mixing effect.

[0006] However, all of the above devices have the following drawbacks:

[0007] Although the above-mentioned device can thoroughly mix the raw materials, the tank is not equipped with a cleaning structure, which causes the raw materials on the diffuser plate to easily adhere to the inner wall of the tank. This requires the staff to stop the machine and clean it manually, which is not only cumbersome to operate, but also time-consuming and labor-intensive. Summary of the Invention

[0008] The purpose of this invention is to solve the problems in the prior art by proposing a mixing device that can achieve integrated stirring and cleaning, reduce manual intervention, and avoid uneven mixing or cross-contamination caused by clumping on the tank wall.

[0009] To achieve the above objectives, this utility model proposes a mixing device, including a base plate, a mixing tank, a stirring shaft, cleaning components, a stirring rod, a cleaning rod, a cleaning plate, and a cleaning brush. The mixing tank is located above the base plate, and a stirring shaft is rotatably mounted inside the mixing tank. Cleaning components are located above and below the outer wall of the stirring shaft, and a stirring rod is located between two sets of cleaning components. The cleaning components include a cleaning rod, a cleaning plate, and a cleaning brush. The cleaning rods are arranged symmetrically front to back, and a cleaning plate is located at the ends of the cleaning rods that are far apart from each other. A cleaning brush is located on the side wall of each cleaning plate, and the end of the cleaning brush is in close contact with the inner side wall of the mixing tank.

[0010] Preferably, the mixing tank is provided with a feed inlet at the top, and the feed inlet communicates with the interior of the mixing tank.

[0011] Preferably, the stirring rods are divided into two groups, with four stirring rods in each group, and the four stirring rods are distributed in a ring with equal spacing.

[0012] Preferably, the top of the stirring shaft extends through the top of the mixing tank and is equipped with a worm gear.

[0013] Preferably, a concave support is provided above the mixing tank, and a rotating shaft is rotatably provided on the inner side of the concave support. A worm is provided in the middle of the outer wall of the rotating shaft, and the worm is meshed with a worm wheel.

[0014] Preferably, the side wall of the concave support is equipped with a motor, and the output shaft of the motor passes through the inner side of the concave support and is connected to the rotating shaft.

[0015] Preferably, the bottom end of the stirring shaft is symmetrically provided with L-shaped support rods, and the ends of the L-shaped support rods are all provided with scrapers, the lower end face of the scrapers being in close contact with the inner bottom wall of the mixing tank.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model achieves integrated mixing and cleaning through the combined action of the cleaning component and the stirring rod. When the stirring shaft rotates, it synchronously drives the cleaning component and the stirring rod. Since the stirring rod is distributed in a ring with equal spacing, it can evenly mix the raw materials during rotation, ensuring the uniformity of the raw materials. At the same time, the cleaning brush scrapes and cleans the inner wall of the mixing tank under the rotation of the stirring shaft, thereby avoiding uneven mixing or cross-contamination caused by clumping on the tank wall. There is no need for staff to stop the machine for cleaning. The operation is simple, time-saving and labor-saving. It solves the problem that the raw materials on the diffuser plate are easy to adhere to the inner wall of the tank due to the lack of a cleaning structure inside the tank, which requires staff to stop the machine for manual cleaning, which is not only cumbersome but also time-consuming and labor-intensive.

[0018] 2. By setting up a scraper, the stirring shaft drives the scraper to rotate during the rotation process, thereby scraping the raw materials on the inner bottom wall of the mixing tank during the rotation process, avoiding the accumulation of raw materials at the bottom of the mixing tank, and further improving the mixing uniformity of the raw materials.

Detailed Implementation

[0024] See Figures 1 to 4This utility model discloses a mixing device, including a base plate 1, a mixing tank 2, a stirring shaft 3, a cleaning component 4, a stirring rod 5, a cleaning rod 41, a cleaning plate 42, and a cleaning brush 43. The mixing tank 2 is located above the base plate 1. The stirring shaft 3 is rotatably mounted inside the mixing tank 2. The cleaning component 4 is located above and below the outer wall of the stirring shaft 3. The stirring rod 5 is located between two sets of cleaning components 4. The cleaning component 4 includes a cleaning rod 41, a cleaning plate 42, and a cleaning brush 43. The cleaning rod 41 is arranged symmetrically front to back. A cleaning plate 42 is located at the end of each cleaning rod 41 that is far apart from each other. A cleaning brush 43 is located on the side wall of each cleaning plate 42. The end of the cleaning brush 43 is in close contact with the inner side wall of the mixing tank 2. In this application, the cleaning brush 43 is made of nylon material to adapt to the curvature of the tank wall and avoid rigid friction damage.

[0025] See Figure 1 The mixing tank 2 is provided with a feed inlet 21 at the top. The feed inlet 21 communicates with the interior of the mixing tank 2. By setting the feed inlet 21, the raw materials to be mixed can enter the interior of the mixing tank 2 from the feed inlet 21.

[0026] See Figure 2 and Figure 3 The stirring rods 5 are divided into two groups, with four stirring rods 5 in each group. The four stirring rods 5 are distributed in a ring with equal spacing. By distributing the stirring rods 5 in a ring with equal spacing, the stirring rods 5 can evenly stir the raw materials during rotation, ensuring the uniformity of the raw materials.

[0027] See Figure 2 and Figure 3 The top end of the stirring shaft 3 passes through the top of the mixing tank 2 and is equipped with a worm gear 31. By setting the worm gear 31, the stirring shaft 3 can be driven to rotate, thereby driving the cleaning component 4 and the stirring rod 5 to rotate.

[0028] See Figure 4 The mixing tank 2 is provided with a concave support 6 above it. A rotating shaft 61 is rotatably provided on the inner side of the concave support 6. A worm 62 is provided in the middle of the outer wall of the rotating shaft 61. The worm 62 is meshed with the worm wheel 31. When the rotating shaft 61 rotates, it drives the worm 62 to rotate. The worm 62 drives the worm wheel 31 to rotate. The worm wheel 31 drives the stirring shaft 3 to rotate.

[0029] See Figure 4 The concave support 6 is equipped with a motor 7 on its side wall. The output shaft of the motor 7 passes through the inner side of the concave support 6 and is connected to the rotating shaft 61. In this application, the input end of the motor 7 is electrically connected to an external power source. When the motor 7 is started, the motor 7 drives the output shaft to rotate, the output shaft drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the worm gear 62 to rotate.

[0030] See Figure 2and Figure 3 The bottom end of the stirring shaft 3 is symmetrically provided with L-shaped support rods 8, and the ends of the L-shaped support rods 8 are all provided with scrapers 81. The lower end face of the scraper 81 is in close contact with the inner bottom wall of the mixing tank 2, so that the stirring shaft 3 drives the scraper 81 to rotate during the rotation, thereby scraping the raw material on the inner bottom wall of the mixing tank 2 during the rotation, avoiding the accumulation of raw material at the bottom of the mixing tank 2, and further improving the mixing uniformity of the raw material.

[0031] The working process of this utility model:

[0032] In the operation of this mixing device, the raw materials to be mixed are first poured into the feed inlet 21, allowing them to enter the mixing tank 2. Then, the motor 7 is started, driving the output shaft to rotate. The output shaft drives the rotating shaft 61 to rotate, which in turn drives the worm gear 62 to rotate. The worm gear 62 drives the worm wheel 31 to rotate, which in turn drives the stirring shaft 3 to rotate. This, in turn, drives the cleaning component 4 and the stirring rods 5 to rotate. Because the stirring rods 5 are evenly spaced in a ring, they can evenly mix the raw materials during rotation, ensuring uniformity. Simultaneously, the cleaning brush 43, under the rotation of the stirring shaft 3, scrapes and cleans the inner wall of the mixing tank 2, preventing uneven mixing or cross-contamination caused by clumping on the tank wall. Furthermore, the rotation of the stirring shaft 3 drives the scraper 81 to rotate, which scrapes away raw materials from the bottom wall of the mixing tank 0, preventing material accumulation at the bottom and further improving the uniformity of mixing. This method eliminates the need for manual cleaning and is simple to operate, saving time and effort.

[0033] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0034] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
