Description

Technical Field

[0001] This utility model relates to the field of materials manufacturing engineering technology, specifically to a ball mill discharge mechanism for preparing aluminum silver paste. Background Technology

[0002] Aluminum silver paste is a chemical substance used in the manufacture of electronic components such as resistors, capacitors, and inductors. Its main function is to mix aluminum and silver ions to form a thin layer, which can then be used to create the surface of electronic components. Aluminum silver paste has a paste-like consistency and poor flowability.

[0003] Some existing aluminum silver paste ball mills have poor anti-clogging functions in their discharge mechanisms, which can easily cause aluminum silver paste to get stuck in the discharge pipe, resulting in no discharge. Furthermore, the paste tends to adhere to the inner wall of the discharge pipe, making it difficult to clean. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a ball mill discharge mechanism for preparing aluminum silver paste.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ball mill discharge mechanism for preparing aluminum silver paste, including a support platform and a ball mill body. The support platform is provided with a slot, the ball mill body is installed on the upper end of the support platform, and the discharge end of the ball mill body is provided with a discharge pipe that penetrates the slot. A valve is provided on the discharge pipe, and a bottom pipe is provided at the bottom end of the discharge pipe. The discharge pipe is inserted into the interior of the bottom pipe, and the bottom pipe can move up and down along the discharge pipe.

[0008] A ring-shaped block is rotatably mounted at the bottom end of the bottom tube. A crossbar is provided on the inner ring of the ring-shaped block. A column is vertically mounted in the middle part of the crossbar and inserted into the discharge tube. Multiple stirring rods and scraping rods are symmetrically arranged on the outer wall of the column. The scraping rods contact the inner wall of the discharge tube. A first motor is provided on one side of the bottom tube. The output end of the first motor is provided with a gear that meshes with the ring-shaped block.

[0009] When the ball mill body is discharging material, the valve is opened and the first motor is started, causing the gear to drive the ring block to rotate. This causes the column, along with the stirring rod and scraper rod, to rotate inside the bottom tube. Then, the bottom tube is raised, allowing the column to insert into the discharge pipe. At this time, the scraper rod will contact the inner wall of the discharge pipe, providing a stirring effect for the material inside the discharge pipe. The scraper rod can also scrape the material adhering to the inner wall of the discharge pipe.

[0010] To facilitate gear assembly, the present invention includes an improvement whereby the output end of the first motor is provided with a rotating shaft, and the gear is fixed to the bottom end of the rotating shaft by screws.

[0011] Furthermore, an improvement of this utility model is that the scraper rod has a cylindrical structure.

[0012] To facilitate the lifting and lowering of the bottom tube, the present invention includes the following improvements: multiple side plates are symmetrically arranged on the top of the bottom tube; a guide rod penetrating the side plate is provided at the lower end of the ball mill body; the side plate and the guide rod are slidably connected; a second motor is also provided at the lower end of the ball mill body; a side tube is provided on one side of the bottom tube; a threaded rod inserted into the side tube and threadedly connected to the side tube is provided at the output end of the second motor; and the top of the side tube is connected to the bottom tube through a horizontal plate.

[0013] Furthermore, an improvement of this utility model is that both the first motor and the second motor are servo motors.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a ball mill discharge mechanism for preparing aluminum silver paste, which has the following beneficial effects:

[0016] Effectively prevents discharge pipe blockage: This discharge mechanism incorporates a stirring rod and a scraper rod to agitate the material during discharge, keeping it in a flowing state and preventing clumping. The scraper rod also removes material adhering to the inner wall of the discharge pipe, fundamentally solving the problem of discharge pipe blockage and improving the smoothness and efficiency of discharge.

[0017] Easy to clean the discharge pipe: The scraper bar of this mechanism continuously scrapes the inner wall of the discharge pipe during the discharge process, reducing the amount of material adhering. After discharge, the inner wall of the discharge pipe is relatively clean, greatly reducing the difficulty and workload of cleaning, and saving time and labor costs. Attached Figure Description

[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] Please see Figure 1-5 The present invention relates to a ball mill discharge mechanism for preparing aluminum silver paste, comprising a support platform 1 and a ball mill body. The support platform 1 is provided with a slot 3. The ball mill body is installed on the upper end of the support platform 1, and the discharge end of the ball mill body is provided with a discharge pipe 4 that penetrates the slot 3. The discharge pipe 4 is provided with a valve 5. The bottom end of the discharge pipe 4 is provided with a bottom pipe 6, and the discharge pipe 4 is inserted into the interior of the bottom pipe 6. The bottom pipe 6 can move up and down along the discharge pipe 4.

[0026] An annular block 7 is rotatably mounted at the bottom end of the bottom tube 6. A crossbar 8 is provided on the inner ring of the annular block 7. A column 9 is vertically mounted in the middle part of the crossbar 8 and inserted into the discharge tube 4. Multiple stirring rods 10 and scraping rods 11 are symmetrically arranged on the outer wall of the column 9. The scraping rods 11 contact the inner wall of the discharge tube 4. A first motor 12 is provided on one side of the bottom tube 6. A gear 13 that meshes with the annular block 7 is provided at the output end of the first motor 12.

[0027] In this embodiment, the scraper rod 11 is a cylindrical structure.

[0028] Material discharge preparation stage: The ball mill body is installed on the upper end of the support platform 1. The discharge pipe 4 at its discharge end passes through the empty slot 3 on the support platform 1. A valve 5 is installed on the discharge pipe 4 to control the discharge. The bottom end of the discharge pipe 4 is inserted into the bottom pipe 6, which can move up and down along the discharge pipe 4. Before discharge, the valve 5 is closed to ensure that the equipment is in an initial stable state.

[0029] Initiating the stirring and scraping function: When the ball mill body needs to discharge material, open valve 5 and simultaneously start the first motor 12. The output end of the first motor 12 has a rotating shaft, and gear 13 is fixed to the bottom of the rotating shaft with screws. The first motor 12 drives gear 13 to rotate. Since gear 13 meshes with the annular block 7, the rotation of gear 13 will drive the annular block 7 to rotate. A vertical column 9 is vertically installed in the middle of the crossbar 8 of the inner ring of the annular block 7. When the annular block 7 rotates, the column 9 rotates accordingly, and multiple stirring rods 10 and scraping rods 11 symmetrically arranged on the outer wall of the column 9 also rotate together. At this time, the scraping rods 11 contact the inner wall of the discharge pipe 4, and the stirring rods 10 stir the material in the discharge pipe 4, maintaining good material flowability and preventing material from clumping and clogging the discharge pipe 4. Simultaneously, the scraping rods 11 scrape the material adhering to the inner wall of the discharge pipe 4, preventing the material from sticking to the pipe wall.

[0030] In this embodiment, a plurality of side plates 14 are symmetrically arranged on the top of the bottom tube 6. The lower end of the ball mill body is provided with a guide rod 15 that penetrates the side plate 14. The side plate 14 and the guide rod 15 are slidably connected. The lower end of the ball mill body is also provided with a second motor 17. A side tube 16 is provided on one side of the bottom tube 6. The output end of the second motor 17 is provided with a threaded rod 18 that is inserted into the side tube 16 and threadedly connected to the side tube 16. The top of the side tube 16 is connected to the bottom tube 6 through a cross plate.

[0031] Bottom tube 6 lifting and adjustment: To allow the column 9 to be inserted into the discharge pipe 4 for stirring and scraping operations, the bottom tube 6 needs to rise. Multiple side plates 14 are symmetrically arranged at the top of the bottom tube 6. A guide rod 15 at the lower end of the ball mill body passes through the side plates 14, and the side plates 14 are slidably connected to the guide rod 15, providing guidance for the lifting and lowering of the bottom tube 6. The second motor 17 at the lower end of the ball mill body starts, and its output threaded rod 18 is inserted into the side tube 16 on one side of the bottom tube 6 and threadedly connected to it. When the second motor 17 rotates, the threaded rod 18 rotates accordingly. Due to the threaded engagement between the side tube 16 and the threaded rod 18, the bottom tube 6 rises along the guide rod 15, allowing the column 9 to be inserted into the discharge pipe 4. After discharge is complete, the second motor 17 reverses, and the bottom tube 6 descends, returning to its initial position.

[0032] Effectively prevents blockage of the discharge pipe 4: This discharge mechanism uses a stirring rod 10 and a scraper rod 11 to stir the material during the discharge process, keeping the material in a flowing state and preventing clumping. The scraper rod 11 can also scrape off the material adhering to the inner wall of the discharge pipe 4, fundamentally solving the problem of blockage of the discharge pipe 4 and improving the smoothness and efficiency of discharge.

[0033] Facilitates cleaning of the discharge pipe 4: The scraper rod 11 of this mechanism continuously scrapes the inner wall of the discharge pipe 4 during the discharge process, reducing the amount of material adhering. After the discharge is completed, the inner wall of the discharge pipe 4 is relatively clean, greatly reducing the difficulty and workload of cleaning, and saving time and labor costs.

[0034] In this embodiment, both the first motor 12 and the second motor 17 are servo motors.

[0035] To improve the stability and reliability of the equipment: the bottom tube 6 is slidably connected to the guide rod 15 via the side plate 14, which ensures stability during lifting and lowering, preventing swaying and deviation. Both the first motor 12 and the second motor 17 are servo motors. Servo motors have precise control performance and high reliability, accurately controlling the rotation of the annular block 7 and the lifting and lowering of the bottom tube 6, ensuring stable operation throughout the entire discharge process, and improving the reliability and service life of the equipment.

[0036] In this embodiment, the output end of the first motor 12 is provided with a rotating shaft, and the gear 13 is fixed to the bottom end of the rotating shaft by screws.

[0037] Facilitating gear 13 assembly: The output end of the first motor 12 is equipped with a rotating shaft, and gear 13 is fixed to the bottom end of the rotating shaft with screws. This design makes the assembly and disassembly of gear 13 more convenient, facilitating equipment maintenance and repair. When gear 13 wears or malfunctions, it can be quickly replaced, reducing equipment downtime and improving production efficiency.

[0038] Optimize the design of scraper rod 11: The scraper rod 11 adopts a cylindrical structure, which can better contact the inner wall of the discharge pipe 4, making the scraping process smoother, reducing damage to the inner wall of the discharge pipe 4, and improving the scraping effect.
