Description

Technical Field

[0001] This utility model relates to the field of high-efficiency stirrer technology, specifically a high-efficiency stirrer for raw materials used in the production of piezoelectric ceramics. Background Technology

[0002] High-efficiency mixers for piezoelectric ceramic production typically refer to high-speed, uniform mixing equipment specifically designed for mixing ceramic raw materials. They can effectively mix the raw material powders and slurries required for piezoelectric ceramics, ensuring that the raw materials are uniform and fine, thereby improving product quality and production efficiency.

[0003] In the existing technology, the raw materials for piezoelectric ceramics need to be mixed and stirred during production. However, the mixing efficiency is often low and the mixing is not thorough.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN217164197U) discloses a high-efficiency stirring device for the production of piezoelectric ceramics, including a stirring tank. A sealing box is fixedly connected to the lower inner wall of the stirring tank. A motor is fixedly connected to the inner end of the sealing box. A vertical rod is fixedly connected to the output end of the motor and extends into the stirring tank. Annular electric sliding grooves are symmetrically fixedly connected to the upper and lower sides of the outer end of the vertical rod. When mixing piezoelectric ceramic raw materials using the stirring tank, two sliding blocks are first driven to rotate in the front and rear directions by the two annular electric sliding grooves in the vertical rod. This causes the rotating fan located at the outer end of the two sliding blocks to come into contact with the two sides. At the same time, multiple fragment holes on their surfaces mesh with the corresponding protruding pressure columns, which can break up agglomerated particles in various powders, thereby improving the mixing efficiency of raw materials in the stirring tank.

[0005] Although the existing technology can overcome the shortcomings mentioned above, there are still other problems in its operation, such as: when stirring, unidirectional stirring is prone to insufficient stirring effect, resulting in poor stirring effect and insufficient mixing of piezoelectric ceramic raw materials. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency stirrer for raw materials in the production of piezoelectric ceramics, in order to solve the problem mentioned in the background art that unidirectional stirring easily leads to insufficient stirring effect, resulting in poor stirring effect and insufficient mixing of piezoelectric ceramic raw materials.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency mixer for raw materials in piezoelectric ceramic production, comprising a mixing chamber and a base mounted at the lower end of the mixing chamber, wherein the upper end of the mixing chamber is provided with a feed inlet, and the lower end of the feed inlet is connected to a discharge valve; a drive motor is mounted at the upper end of the mixing chamber, and a power rod is mounted at the output end of the drive motor, and an auxiliary stirring mechanism is provided at the lower end of the power rod; a rotating rod is rotatably mounted at the rear end of the mixing chamber, and an auxiliary discharge mechanism is provided at the lower end of the rotating rod.

[0008] Furthermore, the auxiliary stirring mechanism is provided with a silicone rod, the upper end of which is fixedly installed on the lower end of the power rod, and the lower end of the silicone rod is fixedly installed with a stirring blade rod.

[0009] Furthermore, a disc rod is rotatably mounted on the upper end of the mixing chamber, and a positioning post is mounted on the outer side of the lower end of the disc rod. An auxiliary push rod is sleeved on the surface of the positioning post, and an arc block is mounted on the right end of the auxiliary push rod. The arc block corresponds to the upper end of the stirring blade rod. The upper end of the disc rod is synchronously rotated with the power rod through a belt and a pulley.

[0010] Furthermore, a limiting sleeve is installed through the middle of the auxiliary push rod, and the upper end of the limiting sleeve is fixedly installed on the inner wall of the mixing chamber.

[0011] Furthermore, the auxiliary discharge mechanism is provided with a guide column, the upper end of which penetrates the mounting base, and the lower end of the guide column is fixedly installed with an inclined striking plate, the front end of which is aligned with the lower inclined part of the mixing chamber.

[0012] Furthermore, the rotating rod is synchronously rotated with the power rod via a belt and a pulley, and a cam is fixedly installed at the lower end of the rotating rod.

[0013] Furthermore, a vibration spring is sleeved on the surface of the guide post, and the upper and lower ends of the vibration spring are installed between the base and the inclined striking plate. An inclined block is installed at the lower end of the inclined striking plate, and the inclined block corresponds to the cam.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. During use, add an appropriate amount of piezoelectric ceramic raw material into the mixing chamber through the feed inlet. Start the drive motor, which drives the power rod to rotate. When the power rod rotates, it can reciprocate through the arc block on the right end to push the stirring blade rod connected to the silicone rod. When the stirring blade rod rotates, it can swing back and forth, further improving the mixing effect and achieving efficient mixing, thus improving the efficiency of the agitator.

[0016] 2. As the power rod rotates, it drives the rotating rod at the rear end of the mixing chamber to rotate via the belt pulley. When the rotating rod rotates, it can pass through the base and drive the cam to rotate. When the tilting striking plate is pushed, it can pass through the guide column along the base and squeeze the vibration spring. The tilting striking plate strikes the bottom of the mixing chamber upwards, achieving the effect of vibration discharge and assisting the discharge valve in discharging the piezoelectric ceramic raw materials.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: As Figure 1 , Figure 3 , Figure 4 and Figure 5The technical solution shown is a high-efficiency mixer for raw materials in piezoelectric ceramic production. To solve the problem of poor mixing effect, it discloses: a mixing chamber 1 and a base 2 installed at the lower end of the mixing chamber 1; a feed inlet 3 is provided at the upper end of the mixing chamber 1, and a discharge valve 4 is connected to the lower end of the feed inlet 3; a drive motor 5 is installed at the upper end of the mixing chamber 1, and a power rod 6 is installed at the output end of the drive motor 5; an auxiliary stirring mechanism is provided at the lower end of the power rod 6, and the auxiliary stirring mechanism is provided with a silicone rod 7, with the upper end of the silicone rod 7 fixedly installed at the lower end of the power rod 6. The mixing chamber 1 is equipped with a mixing blade rod 8 fixedly installed at the lower end of the silicone rod 7, and a disc rod 9 is rotatably installed at the upper end of the mixing chamber 1. A positioning post 10 is installed on the outer side of the lower end of the disc rod 9, and an auxiliary push rod 11 is sleeved on the surface of the positioning post 10. An arc block is installed at the right end of the auxiliary push rod 11, and the arc block corresponds to the upper end of the mixing blade rod 8. The upper end of the disc rod 9 is synchronously rotated with the power rod 6 through a belt and a pulley. A limit sleeve 12 is installed through the middle end of the auxiliary push rod 11, and the upper end of the limit sleeve 12 is fixedly installed on the inner wall of the mixing chamber 1.

[0026] In use, an appropriate amount of piezoelectric ceramic raw material is added to the mixing chamber 1 through the feed inlet 3. By starting the drive motor 5, the drive motor 5 drives the power rod 6 to rotate. When the power rod 6 rotates, it can drive the silicone rod 7 and the stirring blade rod 8 to rotate, thereby mixing and stirring the piezoelectric ceramic raw material. After the mixing is completed, it is discharged through the discharge valve 4. At the same time, when the power rod 6 rotates, it can drive the disc rod 9 to rotate under the action of the belt and pulley. When the disc rod 9 rotates, it can drive the auxiliary push rod 11 through the positioning column 10 at the bottom. Under the limit of the limiting sleeve 12, the auxiliary push rod 11 can push the stirring blade rod 8 connected to the silicone rod 7 back and forth through the arc block at the right end. When the stirring blade rod 8 rotates, it can swing back and forth, further improving the mixing effect, achieving efficient mixing and improving the efficiency of the agitator.

[0027] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The technical solution shown, based on Embodiment 1, discloses the following to solve the problem of inconvenient material discharge: a rotating rod 13 is rotatably provided at the rear end of the mixing chamber 1, and an auxiliary material discharge mechanism is provided at the lower end of the rotating rod 13. The auxiliary material discharge mechanism is provided with a guide column 16, and the upper end of the guide column 16 passes through the mounting base 2. An inclined striking plate 15 is fixedly installed at the lower end of the guide column 16, and the front end of the inclined striking plate 15 is aligned with the inclined part at the lower end of the mixing chamber 1. The rotating rod 13 is synchronously rotated with the power rod 6 through a belt and a pulley. A cam 14 is fixedly installed at the lower end of the rotating rod 13. A vibration spring 17 is sleeved on the surface of the guide column 16, and the upper and lower ends of the vibration spring 17 are installed between the base 2 and the inclined striking plate 15. An inclined block 18 is installed at the lower end of the inclined striking plate 15, and the inclined block 18 corresponds to the cam 14.

[0028] As the power rod 6 rotates, the power rod 6 drives the rotating rod 13 at the rear end of the mixing chamber 1 to rotate via the belt pulley. When the rotating rod 13 rotates, it can pass through the base 2 and drive the cam 14 to rotate. When the cam 14 rotates, it can squeeze the inclined block 18. Due to its inclined shape, the inclined block 18 is squeezed upward and pushes the inclined striking plate 15. When the inclined striking plate 15 is pushed, it can pass through the guide post 16 along the base 2 and squeeze the vibration spring 17. The inclined striking plate 15 strikes the inclined part at the bottom of the mixing chamber 1 upward, achieving the effect of vibration discharge, and assisting the discharge valve 4 in discharging the piezoelectric ceramic raw material.
