Description

Technical Field

[0001] This utility model belongs to the field of aluminum silver paste production and processing technology, and specifically relates to an aluminum silver paste dispersion device that is easy to maintain. Background Technology

[0002] In the production process of aluminum silver paste, dispersion treatment is an indispensable key process before sieving. Its core requirement is to ensure that the density distribution of aluminum silver paste is uniform and the components are fully dispersed, which is directly related to the quality of subsequent products. At present, the dispersion devices widely used in the industry are mainly divided into two categories, but they both have obvious defects in actual application. Traditional aluminum silver paste dispersion devices rely on mechanical stirring as their core operating method. They mainly consist of an operating platform, a conical cylinder, and a stirring device. The conical cylinder holds the aluminum silver paste to be dispersed, with an outlet valve at the bottom for material discharge. The stirring device comprises a stirring shaft, a spiral stirring paddle, a reducer, and a motor. The motor drives the stirring shaft via the reducer, which in turn drives the spiral stirring paddle to rotate at high speed within the cylinder for dispersion. However, this device has several problems: First, the motor-reducer design for driving the stirring shaft consumes a lot of electricity, increasing production energy consumption. Second, because the aluminum silver paste easily overflows due to vortex action during stirring, the conical cylinder typically only holds half a cylinder of material, severely limiting the single-batch processing capacity and resulting in low dispersion efficiency. Third, the vortices created by the high-speed rotation of the spiral stirring paddle cause uneven density distribution of the aluminum silver paste within the cylinder, with higher density at the top and lower density at the bottom, failing to meet the core requirement of uniform density and directly affecting the dispersion effect and product quality. To address the aforementioned issues, Chinese Patent No. CN205760926U discloses an aluminum silver paste dispersion device. This device adds a gas dispersion component to the dispersion cylinder. This component includes a hollow pipeline and a gas distributor head. The aluminum silver paste is dispersed by injecting gas into the cylinder. This design solves the energy consumption and capacity problems of traditional devices to some extent. It reduces power consumption by eliminating the need for mechanical stirring, and the dispersion cylinder can hold more material to improve efficiency. At the same time, the gas dispersion method helps to improve the uniformity of the aluminum silver paste.

[0003] However, significant shortcomings remain in practical applications. On the one hand, the overall structural design of the device makes it difficult to quickly disassemble and maintain its internal components. When the stirring structure or gas dispersion components malfunction, maintenance operations are cumbersome, affecting production continuity. On the other hand, during the dispersion process, aluminum silver paste residue easily adheres to the inside of the tank and the surface of the stirring structure (if the stirring components are retained), forming stains. The existing structural design makes internal cleaning and cleaning of the stirring mechanism extremely inconvenient, and long-term use can easily affect the dispersion effect due to the accumulation of stains. In addition, the stirring structure design of some devices of this type is simple, which cannot achieve rapid and efficient dispersion and stirring, making it difficult to meet the dispersion efficiency requirements of large-scale production. In summary, existing aluminum silver paste dispersion devices have deficiencies in energy consumption control, processing efficiency, dispersion uniformity, maintenance convenience, and cleaning convenience, and cannot fully adapt to the needs of modern production for high efficiency, low consumption, and easy maintenance. Therefore, improving the design of existing devices is of great practical significance. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an easy-to-maintain aluminum silver paste dispersion device to solve the problems raised in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An easy-to-maintain aluminum silver paste dispersion device includes a base frame, a tank fixedly installed inside the base frame, a maintenance auxiliary mechanism fixedly installed at the rear end of the base frame, and a stirring mechanism fixedly installed at the front end of the maintenance auxiliary mechanism, the stirring mechanism being inserted into the inner side of the tank.

[0009] As a preferred technical solution, a support guide rod is fixedly installed at both ends of the bottom of the top cover, the bottom end of the support guide rod penetrates through the base frame, and the support guide rod and the base frame are slidably connected.

[0010] As a preferred technical solution, a feeding valve is fixedly installed in the middle of the front end of the top cover.

This achieves the effect of conveniently inspecting and cleaning the stirring mechanism and the tank, and solves the problem of inconvenient disassembly, inspection and cleaning of internal components in the prior art.

[0016] Example refer to Figures 1 to 5 An easy-to-maintain aluminum silver paste dispersion device according to this embodiment includes a base frame 1, a tank 2 fixedly installed inside the base frame 1, a maintenance auxiliary mechanism 3 fixedly installed at the rear end of the base frame 1, a stirring mechanism 4 fixedly installed at the front end of the maintenance auxiliary mechanism 3, the stirring mechanism 4 being inserted into the inner side of the tank 2, a discharge valve fixedly installed at the bottom output end of the tank 2, and a discharge pipe fixedly installed at the output end of the discharge valve. The maintenance auxiliary mechanism 3 includes a vertical rail 31, which is fixedly installed in the middle of the back of the base frame 1. A first motor 32 is fixedly installed at the bottom of the vertical rail 31. A lead screw 33 is fixedly installed through the vertical rail 31 at the output end of the first motor 32. The lead screw 33 is rotatably connected to the inside of the vertical rail 31. A movable block 34 is threadedly connected to the outer surface of the lead screw 33. A bracket 35 is fixedly installed on the top of the movable block 34. A turntable 36 is rotatably connected to the top of the bracket 35. A connecting frame 37 is fixedly installed on the top of the turntable 36. A stirring mechanism 4 is fixedly installed on the outer end of the connecting frame 37. When this technical solution is working, the base frame 1 provides stable support for the entire device. The tank 2 is used to hold the aluminum silver paste to be dispersed. When it is necessary to put the stirring mechanism 4 into the tank 2 for dispersion or remove it from the tank 2 for maintenance, the maintenance auxiliary mechanism 3 starts to operate. After the first motor 32 starts, it drives the lead screw 33 to rotate inside the vertical rail 31. Due to the movable block 34... 4 is threadedly connected to lead screw 33. The rotation of lead screw 33 is converted into linear movement of movable block 34 along vertical rail 31. The movement of movable block 34 drives the support 35, turntable 36, and connecting frame 37 to move synchronously, thereby causing the stirring mechanism 4 to rise and fall accordingly. This allows the stirring mechanism 4 to be inserted or removed inside the tank 2. When the stirring mechanism 4 needs to be adjusted for maintenance, turntable 36 can rotate relative to support 35, causing connecting frame 37 and stirring mechanism 4 to change direction. This allows operators to inspect or clean the stirring mechanism 4 from a more suitable angle. This lifting and turning of the stirring mechanism 4 through maintenance auxiliary mechanism 3 eliminates the need for manual labor to move or disassemble, reducing manpower consumption during maintenance and making the disassembly and maintenance of the stirring mechanism 4 more convenient. It solves the problem of the difficulty in quickly disassembling and repairing internal components in existing devices, and also provides convenient conditions for cleaning the inside of the tank 2, improving the maintenance efficiency of the equipment.

[0017] refer to Figures 1-5The movable block 34 has a convex shape when viewed from above, and the internal cavity of the vertical rail 31 also has a convex shape. A base plate 5 is fixedly installed at the bottom of the base frame 1, and the bottom of the base plate 5 has anti-slip texture. When this technical solution is working, the movable block 34 moves along the internal cavity of the vertical rail 31 under the drive of the lead screw 33. Since the top view shape of the movable block 34 and the internal cavity of the vertical rail 31 are both convex, the two work together to effectively limit the lateral displacement of the movable block 34 during the movement, ensuring that the movable block 34 always moves smoothly up and down along the predetermined trajectory of the vertical rail 31, avoiding the impact of shaking on the mixer. The precise alignment of the structure 4 makes the process of inserting or removing the mixing mechanism 4 into the tank 2 more stable and reliable, reducing the possibility of operational errors. The bottom plate 5 at the bottom of the base frame 1 increases the contact area with the ground, enhancing the overall stability of the device. The anti-slip texture on the bottom of the bottom plate 5 further increases the friction between the device and the ground. When the equipment is running, especially when the mixing mechanism 4 is running at high speed and vibrating, it can effectively prevent the device from shifting or sliding, ensuring the safety and stability of decentralized operations. It provides a reliable foundation for the normal operation of the entire device, indirectly improving the continuity of equipment operation and work efficiency.

[0018] refer to Figures 2-5 The stirring mechanism 4 includes a top cover 41, which is fixedly installed on the outer end of the connecting frame 37. A second motor 42 is fixedly installed in the middle of the top of the top cover 41. The output end of the second motor 42 passes through the top cover 41 and a stirring frame 43 is fixedly installed thereon. The stirring frame 43 is inserted into the inside of the tank 2. Supporting guide rods 44 are fixedly installed at both ends of the bottom of the top cover 41. The bottom ends of the supporting guide rods 44 pass through the base frame 1 and are slidably connected to the base frame 1. A feeding valve 45 is fixedly installed in the middle of the front end of the top of the top cover 41. The output end of the feeding valve 45 passes through the top cover 41 and is connected to the inside of the tank 2. A guide bucket 46 is fixedly connected to the top of the feeding valve 45. When this technical solution is working, the top cover 41 of the stirring mechanism 4 moves with the movement of the connecting frame 37. When the stirring frame 43 needs to enter the tank 2 for dispersion operations, the top cover 41 descends and closes onto the tank 2. At the top, the operator adds aluminum silver paste into the tank 2 through the guide bucket 46 at the top of the feeding valve 45. The feeding valve 45 controls the addition process of the raw materials, and the guide bucket 46 guides the raw materials to enter smoothly, reducing spillage. After the raw materials are added, the second motor 42 starts, and its output end drives the stirring frame 43 to rotate. The stirring frame 43 stirs and disperses the aluminum silver paste in the tank 2. During the stirring process, the supporting guide rod 44 at the bottom of the top cover 41 moves synchronously with the top cover 41. Its bottom end passes through the base frame 1 and slides through the base frame 1, which can limit the shaking of the top cover 41, enhance the overall stability of the stirring mechanism 4, and avoid structural displacement caused by the vibration generated by the high-speed rotation of the stirring frame 43, ensuring that the stirring operation is carried out smoothly. This structural design makes the addition of raw materials more convenient, the stirring process more stable, improves the dispersion efficiency and effect, and also provides a convenient basis for subsequent maintenance operations.

[0019] refer to Figures 4-5 The mixing frame 43 includes a rotating shaft 431, which is rotatably connected to the bottom of the top cover 41. Bending mixing plates 432 are fixedly installed at equal intervals on the outer surface of the rotating shaft 431, and straight mixing plates 433 are fixedly connected at equal intervals on the inner side of the bending mixing plates 432. A stirring auger 434 is fixedly installed at the lower end of the outer surface of the rotating shaft 431. During operation, the rotating shaft 431 of the mixing frame 43 rotates under the drive of the second motor 42, causing the bending mixing plates 432 and straight mixing plates 433 on the outer surface and the stirring auger 434 at the lower end to rotate synchronously. When the bending mixing plates 432 rotate with the rotating shaft 431, they agitate the aluminum silver paste in the tank 2 along a non-linear path, thus affecting materials in different areas. Breaking the aggregation of materials, the straight stirring plate 433 is connected to the inner side of the bent stirring plate 432. As the bent stirring plate 432 moves, it forms a linear stirring force on the surrounding aluminum silver paste, further refining the stirring effect and allowing the material to be more fully sheared and mixed. When the stirring auger 434 at the lower end of the rotating shaft 431 rotates, it pushes the aluminum silver paste at the bottom of the tank 2 upward, preventing the material from settling at the bottom and allowing the aluminum silver paste in the upper and lower parts of the tank 2 to circulate and mix. This multi-component coordinated stirring method allows the aluminum silver paste to be dispersed in the tank 2 in an all-round and multi-layer manner, effectively improving the uniformity of density distribution, improving the dispersion effect, and increasing the dispersion efficiency, providing a more stable raw material for subsequent processes.

[0020] Operating principle and advantages: During the application of this equipment, the base frame 1 is fixed to the ground by the bottom plate 5. The anti-slip texture on the bottom of the bottom plate 5 increases the friction with the ground and prevents the equipment from sliding during operation. The operator adds the aluminum silver paste to be dispersed into the tank 2 through the guide bucket 46 at the top of the feeding valve 45. The feeding valve 45 controls the opening and closing of the raw material addition, and the guide bucket 46 guides the raw material smoothly into the tank 2, reducing the amount of raw material spilled. After that, the maintenance auxiliary mechanism 3 is started, and the first motor 32 drives the lead screw 33 to rotate inside the vertical rail 31. The movable block 34 moves along the vertical rail 31 under the action of the lead screw 33. The rise of the stirring mechanism 4, along with the support 35, turntable 36, connecting frame 37, and stirring mechanism 4, causes the stirring frame 43 to rise synchronously until it is completely detached from the tank 2. After adjusting the position of the stirring mechanism 4 by rotating the turntable 36 as needed, the first motor 32 is started in reverse, causing the movable block 34 to drive the stirring mechanism 4 to descend, allowing the stirring frame 43 to be inserted into the tank 2. The top cover 41 is then placed on top of the tank 2. During this process, the convex cavity inside the vertical rail 31 cooperates with the movable block 34 to ensure stable movement. The turntable 36 provides convenience for subsequent maintenance operations and solves the problem of the difficulty in quickly adjusting the position of internal components in existing equipment. During the mixing and dispersion operation, the second motor 42 starts, and its output end drives the rotating shaft 431 of the mixing frame 43 to rotate. The bent mixing plate 432 and the straight mixing plate 433 on the outer surface of the rotating shaft 431 rotate with the rotating shaft 431, and perform multi-angle mixing of the aluminum silver paste in the tank 2. The straight mixing plate 433 further enhances the mixing uniformity. The mixing auger 434 at the lower end of the rotating shaft 431 rotates and flips the aluminum silver paste at the bottom of the tank 2 upward, avoiding uneven density caused by the accumulation of materials at the bottom. This effectively improves the problem of uneven density distribution in traditional mechanical mixing. During the mixing process, the support guide rod 44 moves synchronously with the top cover 41, enhancing the stability of the top cover 41 and the mixing frame 43 during operation, preventing structural displacement caused by vibration generated by mixing, ensuring smooth mixing operation, and improving the dispersion effect and product quality. When maintenance or cleaning is required, the first motor 32 is started to cause the movable block 34 to drive the stirring mechanism 4 to rise until the stirring frame 43 is completely separated from the tank 2. The turntable 36 is rotated to rotate the stirring mechanism 4 to a position that is easy to operate. The operator can then inspect or clean the stirring frame 43, the top cover 41 and other components. Since the stirring mechanism 4 has been completely removed, the inside of the tank 2 can also be processed directly, which solves the problems of inconvenient cleaning and difficult maintenance in the prior art. After maintenance or cleaning is completed, the stirring mechanism 4 can be reset according to the above steps to continue the operation. The whole process is convenient to operate, which helps to maintain the long-term stable operation of the equipment and meets the needs of large-scale production for high efficiency and easy maintenance. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.
