Description

Technical Field

[0001] This utility model relates to the field of dosing equipment technology, specifically a fully automatic seed crystal weighing and metering dosing device. Background Technology

[0002] Seed crystal weighing and metering equipment is a key piece of equipment for precisely controlling the amount of seed crystals added in crystallization processes. It is mainly used in chemical, pharmaceutical, semiconductor, and material synthesis fields. By accurately weighing and quantitatively adding seed crystals (such as single crystal particles, polycrystalline powders, or nano-sized seed crystals), it ensures that the amount of seed crystals added strictly matches the process formulation requirements during solution crystallization, melt growth, or vapor deposition. This avoids crystal agglomeration caused by excessive addition or low nucleation efficiency caused by insufficient addition, thereby ensuring the uniformity of crystal growth, controllable particle size, and stable quality of the finished product. It is an important support for improving the precision and production efficiency of crystallization processes.

[0003] During the use of the feeding equipment, the weighing device may become unstable and shaky when weighing the seed crystals, affecting the weighing accuracy. Furthermore, material accumulation and blockage may occur during the feeding process, impacting feeding efficiency. Therefore, improvements are needed. Utility Model Content

By designing this locking mechanism, the partition can be limited and locked.

[0007] Preferably, there are multiple grooves, which are arranged in a ring shape and evenly distributed inside the storage tank. By designing multiple grooves, the insertion and engagement of the grooves with the retaining ball can improve the limiting effect on the partition.

[0008] Preferably, one end of the first spring is fixedly connected to the slider, and the other end of the first spring is fixedly connected to the partition. By designing the first spring, its force can be applied to the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a drive motor to rotate the stirring rod, which agitates the material and prevents it from accumulating and clogging. The weighing device weighs the material. After the material is weighed, the solenoid valve closes and the first motor drives the partition to flip, thus discharging the weighed material. This allows for automatic material addition. The ball and groove are engaged to limit the partition during weighing, maintaining its stability and preventing shaking that could affect the weighing accuracy.

[0014] 2. By designing a second motor, the output of the second motor can drive the rotating seat and the arc block to rotate. When the arc block rotates and comes into contact with the storage tank, it can collide and impact the storage tank, thereby vibrating the lower structure of the storage tank. During the material feeding process, it can prevent material from accumulating and blocking the discharge port, thus affecting the feeding efficiency. Attached Figure Description

The storage tank 1 has a groove 81 inside, and a retaining ball 82 is movably sleeved inside the groove 81. There are multiple grooves 81, which are arranged in a ring and evenly distributed inside the storage tank 1. By designing multiple grooves 81, the insertion and cooperation between the multiple grooves 81 and the retaining ball 82 can improve the limiting effect on the partition 7. The retaining ball 82 is movably connected to the partition 7. A slider 83 is movably sleeved on the outside of the retaining ball 82. The slider 83 is slidably connected to the partition 7. A sliding rod 84 is fixedly connected to the outside of the slider 83. The sliding rod 84 is slidably connected to the partition 7. A first spring 85 is provided on the outside of the sliding rod 84. One end of the first spring 85 is fixedly connected to the slider 83, and the other end of the first spring 85 is fixedly connected to the partition 7. By designing the first spring 85, the force of the first spring 85 can act on the slider 83. By designing the locking mechanism 8, the partition 7 can be limited and locked.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The feeding mechanism 9 includes a second motor 91. The second motor 91 is fixedly installed at the left end of the storage tank 1. A rotating seat 92 is fixedly connected to the upper end of the output end of the second motor 91. An arc-shaped block 93 is slidably sleeved inside the rotating seat 92. The arc-shaped block 93 contacts the storage tank 1. A guide rod 94 is slidably sleeved inside the arc-shaped block 93. The guide rod 94 is fixedly connected to the rotating seat 92.

By designing the guide groove 97, the guide block 96 can slide along the guide groove 97. By designing the feeding mechanism 9, blockage during material feeding can be prevented.

[0024] The specific implementation process of this utility model is as follows: In use, the material is placed inside the storage tank 1 for storage. When the material needs to be added, the solenoid valve 6 is opened, and at the same time, the output end of the drive motor 3 drives the rotating shaft 4 and the stirring rod 5 to rotate, which can stir the material to avoid material accumulation and blockage. The material is discharged downward through the solenoid valve 6 and falls on the weighing device 10 for weighing. After the weighing is completed, the solenoid valve 6 is closed, and then the first motor 11 works to drive the partition 7 to rotate. The partition 7 will drive the ball 82 to rotate. The ball 82 will roll along the arc surface of the groove 81. The ball 82 will be squeezed and pushed to roll outward. The ball 82 will drive the slider 83 and the sliding rod 84 to move horizontally. The slider 83 can squeeze the first spring 85, which can realize the separation of the ball 82 from the groove 81. Then the material can be discharged through the storage tank 1 to carry out the material addition work. When the first motor 11 reverses and resets, it can re-close the storage tank 1, and the ball 82 can also be reset and rolled into the groove 81 under the elastic action of the first spring 85. Through the insertion and cooperation of the ball 82 and the groove 81, the partition 7 can be limited during weighing to maintain the stability of the partition 7 and avoid the shaking during weighing from affecting the weighing accuracy.

[0025] During the material feeding process, the second motor 91 works simultaneously. The output end of the second motor 91 drives the rotating seat 92 and the arc block 93 to rotate. After the arc block 93 rotates and comes into contact with the storage tank 1, it will be squeezed and pushed into the rotating seat 92 to slide. The arc block 93 will slide along the guide rod 94 and squeeze the second spring 95. At the same time, the arc block 93 will drive the guide block 96 to slide along the guide groove 97. When the arc block 93 rotates and comes into contact with the storage tank 1, it can collide and impact the storage tank 1, which can realize the vibration of the lower structure of the storage tank 1. During the material feeding process, it can avoid the accumulation of materials blocking the discharge port and affecting the feeding efficiency.
