Abstract
Description
Technical Field
[0001] This invention belongs to the field of mechanical manufacturing technology and relates to a device for manufacturing and storing lead granules. Background Technology
[0002] Lead granules, a key raw material for manufacturing lead powder, are in high demand across numerous industrial sectors, including battery manufacturing and chemicals. Traditional lead granule manufacturing and storage processes typically involve multiple independent pieces of equipment and steps, including lead ingot feeding, pressing, granulation, and subsequent storage. However, these dispersed pieces of equipment and steps present numerous problems in actual production, impacting production efficiency and product quality.
[0003] In the lead ingot feeding process, uneven and discontinuous feeding often occurs, leading to unstable raw material supply for subsequent tableting processes, affecting tableting quality and efficiency. During tableting, uneven pressure distribution or unreasonable spacing of the pressure rollers can easily cause inconsistent lead sheet thickness, thus affecting granulation uniformity. In the granulation stage, insufficient precision and coordination of the cutting rollers may result in inconsistent lead granule sizes, or even failure to cut the lead sheets. Regarding storage, existing storage methods may lead to problems such as lead granule moisture absorption and oxidation, as well as difficulties in handling and cleaning storage containers. To address these issues, the following solutions are currently available:
[0004] To address the issue of uneven feeding, some manufacturers have adopted vibrating feeders or precision conveying screws. However, the former may lead to excessive vibration and dispersion of the raw materials, while the latter has a complex structure and high maintenance costs.
[0005] In terms of improving tableting quality, some companies use more complex pressure roller adjustment mechanisms, but these are difficult to adjust and require highly skilled operators. To improve granulation precision, some companies use high-precision cutting tools and complex control systems, but this increases equipment costs and maintenance difficulty. In terms of lead granule storage, some solutions use containers with better sealing performance, but these are often more expensive and it is difficult to guarantee long-term sealing performance in actual use.
[0006] Taking into account the advantages and disadvantages of these solutions in the production process, this utility model of lead granule manufacturing and storage device adopts an innovative design and optimized process. Stable and uniform feeding is achieved through a unique feed inlet and conveying device design; optimized pressure roller structure and spacing ensure tableting quality; high-precision meshing cutting rollers and reasonable drive motor control guarantee granulation uniformity; and a convenient and practical storage box is designed to solve related problems in lead granule storage. This achieves an integrated, efficient, and stable continuous production process encompassing lead ingot feeding, tableting, granulation, and lead granule storage. Summary of the Invention
[0007] This invention provides a lead granule manufacturing and storage device to realize an integrated, efficient, and stable continuous production process of lead ingot feeding, tableting, granulation, and lead granule storage.
[0008] To solve the above problems, the technical solution adopted by the invention is as follows:
[0009] A lead granule manufacturing and storage device, characterized in that it includes a pressing device, wherein a first pressure roller, a second pressure roller, and a third pressure roller are arranged sequentially from top to bottom within the pressing device; a feed inlet is provided on one side of the pressing device; a conveying device is provided on one side of the pressing device, the conveying device being connected to the feed inlet on the pressing device; a conveying plate is provided within the pressing device, the conveying plate being disposed between the second and third pressure rollers via a torsion spring shaft; a second pushing mechanism is provided on the conveying plate, the second pushing mechanism being disposed parallel to the side of the pushing plate near the shaft; a granulation device is provided on one side of the pressing device, the granulation device containing multiple cutting rollers that are meshed with each other; a drive motor is provided on one side of the granulation device, the output shaft of the drive motor being fixedly connected to the cutting rollers; and a storage box is provided at the lower end of the granulation device.
[0010] The principle behind this solution is:
[0011] The lead ingot raw material is conveyed to the feed port of the pressing device by the conveying device to achieve stable feeding. After the lead ingot enters the pressing device, it is squeezed by the first pressure roller, the second pressure roller and the third pressure roller in sequence to gradually form lead sheets. The conveying plate located between the second pressure roller and the third pressure roller can flexibly guide the conveying direction of the lead sheets through the torsion spring shaft. The second pushing mechanism on the conveying plate helps to accurately push the lead sheets to the next process.
[0012] After being compressed, the lead sheets enter the granulation device. Inside the granulation device, multiple intermeshing cutting rollers, driven by a motor, cut the lead sheets into uniform lead pellets.
[0013] Finally, the cut lead pellets fall into a storage box at the bottom of the pelletizing device for temporary storage, so that they can be processed and used later.
[0014] The beneficial effects of this solution are:
[0015] In the tableting process, multiple pressure rollers are used to gradually compress the lead ingots, ensuring that the lead sheets have a uniform thickness and guaranteeing the stability of the lead particle size and quality.
[0016] The design of the conveyor plate and pushing mechanism effectively solves the problems of jamming and positional deviation that may occur when lead sheets are conveyed between pressure rollers. The torsion spring shaft allows the conveyor plate to flexibly adapt to different pressures and material conditions, while the pushing mechanism ensures that the lead sheets enter the next process accurately, thus improving the reliability and stability of production.
[0017] The interlocking cutting rollers in the granulation device, under the control of the drive motor, can cut lead sheets into uniform lead pellets, improving the consistency of product quality and meeting the strict requirements of subsequent production for lead pellet specifications. At the same time, the cutting of the pellets is fast.
[0018] The storage box located at the bottom of the granulation unit facilitates the temporary storage and centralized management of lead pellets, preventing them from scattering and becoming messy. This helps maintain a clean and orderly production site and also provides convenience for subsequent transportation and further processing.
[0019] Furthermore, the third pressure roller is longer than the second and first pressure rollers and is arranged in parallel. Each pressure roller is fixedly connected by an independent drive motor for driving the pressure roller. The longer design of the third pressure roller increases its contact area with the lead sheet, thereby providing a more uniform pressure distribution during the pressing process. This helps to further ensure the thickness uniformity and surface flatness of the lead sheet, and improve the pressing quality. Each pressure roller is fixedly connected by an independent drive motor, which enables independent control of the speed and torque of each pressure roller.
[0020] Furthermore, a limiting plate is provided on one side of the third pressure roller. This limiting plate is configured in conjunction with the conveying plate to prevent the conveying plate from continuing to rotate downwards when it reaches the third pressure roller, thus ensuring the stability of the conveying plate and improving the conveying stability of the lead sheets on the conveying plate.
[0021] Furthermore, the conveyor plate is equipped with multiple parallel rollers that cooperate with the conveyor plate. The cooperation of these parallel rollers with the conveyor plate reduces the friction between the lead sheet and the conveyor plate. This makes the lead sheet move more smoothly during transport, ensuring that it maintains a stable posture and preventing tilting or flipping.
[0022] Furthermore, the cutting rollers consist of two meshing rollers with multiple cavities. Die cutters are positioned around each cavity. Using two meshing cutting rollers improves cutting efficiency. The two rollers cut the lead sheet simultaneously, processing more material in the same amount of time compared to a single roller, thus accelerating production. The multiple cavity design allows for the simultaneous cutting of multiple lead pellets in a single rotation, increasing output per unit time. The even distribution of the cavities helps ensure consistency in the size and shape of the cut lead pellets, improving product quality stability. The die cutters around the cavities ensure precise and clean cutting, allowing the lead sheet to be quickly and cleanly cut upon entering the cavity, reducing burrs and irregularities during the cutting process and improving the edge quality of the lead pellets.
[0023] Furthermore, a conveyor belt is provided on one side of the tableting device and the granulation device. One end of the conveyor belt is on the same horizontal plane as the third pressure roller, and the other end extends between the cutting rollers, realizing a seamless connection between the tableting and granulation processes. After the lead sheets come out of the third pressure roller, they can fall directly and smoothly onto the conveyor belt and be quickly and accurately transported between the cutting rollers. This avoids the lead sheets from falling, accumulating, or deviating in position during the transfer process, thereby ensuring the continuity and stability of the production process. There is no need for manual handling of the lead sheets, which reduces the error rate and labor costs of manual operation, and also improves the safety of production, avoiding possible injuries to workers during handling.
[0024] Furthermore, a drying layer is provided on the inner side of the storage box. This drying layer is arranged in a ring inside the storage box, allowing it to come into contact with the air inside the storage box from all directions, thereby more effectively absorbing moisture from the air. Regardless of the position of the lead particles within the storage box, they can remain in a dry environment, minimizing the risk of moisture absorption and ensuring the quality and performance of the lead particles.

[0026] Figure 2 for Figure 1 A magnified view of a portion of the image;
[0027] Figure 3 This is a schematic diagram of the structure of this utility model; Detailed Implementation
[0028] The reference numerals in the accompanying drawings include: conveying mechanism 1, conveying motor 2, first pushing mechanism 3, first pressure roller 4, conveyor belt 5, cutting roller 6, mold cavity 7, mold knife 8, storage box 9, drying layer 10, conveying plate 11, roller 12, second pushing mechanism 13, torsion spring shaft 14, limiting block 15, rotating motor 16, granulation device 17, tableting device 18, fixed seat 19, conveying device 20, second pressure roller 21, and third pressure roller 22.
[0029] The basic implementation examples are as follows: Figure 1-3As shown, a lead granule manufacturing and storage device includes a pressing device 18, a conveying device 20, a granulation device 17, and a storage box 9. Within the pressing device 18, a first pressure roller 4, a second pressure roller 21, and a third pressure roller 22 are arranged sequentially from top to bottom. The first pressure roller 4 initially compresses the lead ingots, the second pressure roller 21 further compacts them, and the third pressure roller 22, being longer than the former two, increases the contact area with the lead sheet, providing a more uniform pressure distribution, ensuring uniform lead sheet thickness and a smooth surface, and improving the pressing quality. A feed inlet is provided on one side of the pressing device 18, and the feed inlet is connected to the conveying device 20, which stably transports the lead ingot raw materials into the pressing device 18.
[0030] A conveyor plate 11 is provided inside the tablet pressing device 18. The conveyor plate 11 is set between the second pressure roller 21 and the third pressure roller 22 via a torsion spring shaft 14. A second pushing mechanism 13 is provided on the conveyor plate 11. The torsion spring shaft 14 enables the conveyor plate 11 to flexibly adapt to different pressure and material conditions. The pushing mechanism ensures that the lead sheets enter the next process accurately, effectively avoiding possible jamming and positional deviation when the lead sheets are conveyed between the pressure rollers, thus improving the reliability and stability of production.
[0031] The granulation device 17 is located on one side of the tableting device 18. Inside, there are two meshing cutting rollers 6, each with multiple die cavities 7. Die cutters 8 are positioned around each die cavity 7. The two cutting rollers 6 operate simultaneously, improving cutting efficiency and allowing more material to be processed in the same amount of time, thus accelerating production. The multiple evenly distributed die cavities 7 can simultaneously cut multiple lead pellets, increasing output per unit time, ensuring consistency in lead pellet size and shape, and improving product quality stability. The die cutters 8 ensure precise and clean cutting, reducing burrs and irregularities, and improving the edge quality of the lead pellets.
[0032] A conveyor belt 5 is installed on one side of the tableting device 18 and the granulation device 17. One end of the conveyor belt 5 is on the same horizontal plane as the third pressure roller 22, and the other end extends between the cutting rollers 6. This achieves seamless connection between the tableting and granulation processes. After the lead sheets come out of the third pressure roller 22, they can fall smoothly onto the conveyor belt 5 and be accurately and quickly transported between the cutting rollers 6. This avoids the lead sheets falling, accumulating, or deviating in position during the transfer process, ensuring the continuity and stability of the production process, reducing the error rate and labor costs of manual operation, and improving production safety.
[0033] The lower end of the granulation device 17 is provided with a storage box 9, and a drying layer 10 is arranged in a ring on the inner side of the storage box 9. The ring-shaped drying layer 10 can come into contact with the air inside the storage box 9 in all directions, and absorb moisture more effectively. No matter where the lead particles are in the storage box 9, they can be in a dry environment, reducing the risk of the lead particles getting damp and ensuring their quality and performance.
[0034] In actual operation, lead ingots are placed on conveying device 20, which conveys the lead ingots at a uniform speed to the feed port of pressing device 18. After the lead ingots enter the pressing device 18, their shape begins to change under the initial compression of the first pressure roller 4. Then, they are further compacted by the second pressure roller 21 and then by the third pressure roller 22. Because the third pressure roller 22 is longer, the pressure applied is more uniform, and the thickness of the lead sheet reaches the expected uniformity and flatness.
[0035] Under the action of the torsion spring shaft 14, the conveyor plate 11 rotates flexibly according to the conveying of the lead sheet. At the same time, the second pushing mechanism 13 accurately pushes the lead sheet onto the third pressure roller 22. Through the action of the second pressure roller 21 and the third pressure roller 22, the lead sheet is flattened and uniform, and then conveyed to the conveyor belt 5. The conveyor belt 5 quickly sends the lead sheet to the granulation device 17.
[0036] Two meshing cutting rollers 6 inside the pelletizing device 17 rotate at high speed. Due to the meshing design of the mold cavity 7 and the die 8, the lead sheet is quickly and neatly cut into lead pellets of a specified size and shape. The cut lead pellets fall into the storage box 9. The annular drying layer 10 inside the storage box 9 effectively keeps the internal environment dry and prevents the lead pellets from getting damp.
