Description

Technical Field

[0001] This utility model relates to the field of magnetic material production, specifically to a vibration feeding device. Background Technology

[0002] In modern industry, quartz sand is a crucial basic material widely used in numerous sectors, including glass, ceramics, casting, electronics, and photovoltaics. The precision and uniformity of its particle size play a decisive role in the quality of the final product. For example, in the manufacturing of high-end electronic chips, the quartz sand raw material used must undergo extremely fine sieving to ensure that its particle size meets the requirements of ultra-micro processing techniques.

[0003] However, traditional methods of quartz sand screening mostly rely on a combination of manual operation and simple mechanical devices. Manual operation has many limitations. On the one hand, manual screening efficiency is extremely low, making it difficult to meet the huge demand for quartz sand in large-scale industrial production. Workers need to work continuously for long periods, and during the screening process, subjective factors such as fatigue and distraction make it difficult to guarantee the consistency and stability of screening accuracy. On the other hand, labor costs are high; with changes in the labor market, labor costs are constantly rising, which undoubtedly increases the production burden on enterprises.

[0004] Existing simple mechanical screening devices, such as fixed-mesh vibrating screens, while improving screening efficiency to some extent, still have significant shortcomings. Their automation level is low, typically requiring manual assistance for feeding and unloading. This reduces production efficiency during the screening process, and frequent start-ups and shutdowns also negatively impact the equipment's lifespan. Summary of the Invention

[0005] The problem this invention aims to solve is to provide a vibrating feeding device that addresses the issues of poor stability, low efficiency, and short lifespan associated with the combination of manual operation and simple mechanical devices.

[0006] The technical solution adopted by this utility model to solve the above problems is a vibrating feeding device, including a base, a feeding position, a screening position, and a conveying mechanism. Above the screening position, the base is equipped with a vibrating disc, a storage box, and a buffer mechanism. The storage box is used to store quartz sand, and its bottom has a number of screening holes evenly arranged in an array to allow the quartz sand to pass through. The vibrating disc is placed above the storage box, and the buffer mechanism is installed below the storage box. When the vibrating disc is working, it presses down on the storage box and transmits vibration, causing the storage box to bounce up and down. The buffer mechanism is used to effectively withstand the vibration of the storage box. A sliding plate is installed on the conveying mechanism, and the conveying mechanism drives the sliding plate to move between the feeding position and the screening position. A receiving box is placed on the sliding plate to receive the quartz sand falling from the screening holes when the conveying mechanism moves the sliding plate to the screening position.

[0007] This vibrating screening device aims to solve several key problems in the quartz sand screening process and offers significant advantages. Traditional screening methods face numerous challenges, including low screening efficiency, easy screen clogging, inconvenient material transfer, and a lack of effective vibration buffering. In this device, the vibrating disc causes the storage box to bounce up and down, greatly improving screening efficiency. Dynamic screening effectively reduces screen hole clogging, ensuring continuous and smooth screening. The conveying mechanism, in conjunction with the sliding plate and receiving box, automates material placement, screening, and collection, optimizing process continuity. The buffering mechanism effectively absorbs the vibration of the storage box, ensuring stable equipment operation, reducing component damage, and improving screening accuracy and stability. Its advantages are clear: the vibration of the storage box allows for thorough stratification of the quartz sand, enabling precise screening by particle size and meeting the particle size requirements of different scenarios. The automated process reduces manual intervention, lowers costs, and aligns with the trend of industrial automation. Stable operation is achieved through the buffering mechanism, reducing the probability of failure and ensuring production continuity. With a compact overall structure and high integration, all components work together on the base, demonstrating excellent characteristics in terms of space utilization, installation, debugging and maintenance.

[0008] Furthermore, the conveying mechanism includes two slide rails mounted on the base and a drive cylinder. One end of the two slide rails precisely corresponds to the material feeding position set on the base, while the other end corresponds to the material screening position. Two matching sliding blocks are fixed on both sides of the bottom surface of the sliding plate, and the two sliding blocks are slidably connected to the corresponding two slide rails. A drive frame is installed on the bottom surface of the sliding plate between the two sliding blocks, and the drive frame is fixedly connected to the output end of the drive cylinder. The conveying mechanism is crucial for the material flow of the vibrating screening device. The two slide rails on the base, with one end precisely aligned with the material feeding position and the other end aligned with the material screening position, provide stable guidance for the sliding plate. The sliding blocks on both sides of the bottom surface of the sliding plate are tightly fitted with the slide rails, ensuring smooth and stable sliding and reducing energy consumption and component wear. The drive frame between the two sliding blocks is fixedly connected to the output end of the drive cylinder, receiving its power and transmitting it evenly to the sliding plate. The drive cylinder works according to instructions, causing the sliding plate to move back and forth along the slide rails between the material feeding and screening positions, realizing the orderly transfer of quartz sand in different processes and ensuring continuous production of the device.

[0009] Furthermore, a buffer is also installed on the base, located at the end of the slide rail corresponding to the screening position. The additional buffer installed on the base is located at the end of the slide rail corresponding to the screening position. Its main function is to effectively absorb this excess kinetic energy when the sliding plate moves at high speed along the slide rail to the end of the screening position under the action of the drive cylinder. Due to inertia, the sliding plate still possesses considerable kinetic energy. The buffer can effectively absorb this excess kinetic energy, allowing the sliding plate to stop smoothly at the screening position, avoiding damage to the sliding plate, slide rail, and the entire screening device due to violent collisions. This extends the service life of the equipment and also ensures the accuracy of the relative positions of various components during the screening process, which is beneficial for improving the precision and stability of quartz sand screening and ensuring the smooth operation of the entire screening process.

[0010] Furthermore, the buffer mechanism includes a screening frame positioned above the screening location, with buffer supports symmetrically arranged on both sides of the screening frame. Each buffer support includes a support base, which is fixed to one side of the screening frame. Above both ends of the support base, a transfer plate is mounted. One end of the transfer plate is located directly below the storage box, and the other end is connected to the support base by an elastic element. Fasteners secure the transfer plate to the support base. The support base is firmly anchored to one side of the screening frame. The transfer plate above both ends receives vibrations from the storage box at one end, and is connected to the support base via the elastic element at the other end. The elastic element can deform to buffer energy during vibration. Fasteners ensure a reliable connection between the transfer plate and the support base, allowing for fine-tuning of the transfer plate during elastic deformation, maintaining stable operation of the buffer mechanism. This design effectively absorbs vibrations from the storage box, reduces impact on the equipment, ensures a smooth screening process, reduces equipment malfunctions and material screening errors caused by vibration, improves the quality and efficiency of quartz sand screening, and lays the foundation for the stable and efficient operation of the entire screening device.

[0011] Furthermore, a connecting plate is provided at the center of the opening of the storage box. The connecting plate includes a long-side connecting plate along the long side of the storage box and a short-side connecting plate along the short side of the storage box. The two ends of the long-side connecting plate are connected to the middle of the two side walls of the short side of the storage box, and the two ends of the short-side connecting plate are connected to the middle of the two side walls of the long side of the storage box. The output surface of the vibrating disc abuts against the intersection of the long-side and short-side connecting plates. This structural design effectively strengthens and supports the central area of ​​the storage box opening. The close abutment between the output surface of the vibrating disc and the intersection of the long-side and short-side connecting plates ensures that when the vibrating disc starts working, it efficiently and evenly transmits the generated vibration energy to the storage box, causing the storage box to produce stable and coordinated up-and-down reciprocating vibrations. This ensures that the quartz sand is fully vibrated and loosened within the storage box, allowing for more precise screening of quartz sand of different particle sizes through the bottom screening holes, thus improving screening effect and efficiency.

[0012] Furthermore, the diameter of the screen holes is φ2.5mm~3.5mm. Attached Figure Description

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] Please see Figures 1 to 3A vibrating feeding device mainly consists of a base 1 forming its basic structure. The base 1 is clearly divided into a feeding position 2 and a screening position 3, and is equipped with a conveying mechanism 7. The conveying mechanism 7 includes two slide rails 7.1 mounted on the base 1 and a drive cylinder 7.2. One end of one slide rail 7.1 is precisely positioned at the feeding position 2, and the other end corresponds precisely to the screening position 3. Adaptive sliding blocks 7.3 are fixed to both sides of the bottom surface of the sliding plate 8. These sliding blocks 7.3 are slidably connected to the two slide rails 7.1 respectively. A drive frame 7.4 is installed on the bottom surface of the sliding plate 8 between the two sliding blocks 7.3. This drive frame 7.4 is fixedly connected to the output end of the drive cylinder 7.2, thereby realizing the movement of the sliding plate 8 between the feeding position 2 and the screening position 3. Furthermore, a buffer 10 is also installed on the base 1 at the end of the slide rail 7.1 corresponding to the screening position 3.

[0022] Above the screening position 3, the device is equipped with a vibrating plate 4, a storage box 5, and a buffer mechanism 6. The storage box 5 is used to store quartz sand, and its bottom has a large number of screening holes 5.1 with a diameter between φ2.5mm and 3.5mm evenly arranged in an array to allow the quartz sand to pass through smoothly. A connecting plate 5.2 is provided at the center of the opening of the storage box 5. The connecting plate 5.2 consists of a long side connecting plate 5.2.1 along the long side of the storage box 5 and a short side connecting plate 5.2.2 along the short side. The two ends of the long side connecting plate 5.2.1 are connected to the middle of the two side walls of the short side of the storage box 5, respectively. The two ends of the short side connecting plate 5.2.2 are connected to the middle of the two side walls of the long side of the storage box 5, respectively. The output surface of the vibrating plate 4 is tightly abutted against the intersection of the long side connecting plate 5.2.1 and the short side connecting plate 5.2.2. In this way, when the vibrating plate 4 is working, it can press down on the storage box 5 and transmit vibration, causing the storage box 5 to bounce up and down.

[0023] The buffer mechanism 6 includes a screening frame 6.1 positioned above the screening position 3, with buffer supports 6.2 symmetrically arranged on both sides of the screening frame 6.1. Each buffer support 6.2 has a support base 6.2.1 fixed to one side of the screening frame 6.1. Transfer plates 6.2.2 are positioned above both ends of the support base 6.2.1. One end of the transfer plate 6.2.2 is located directly below the storage box 5, and an elastic element 6.2.3 is arranged between the other end and the support base 6.2.1. The transfer plate 6.2.2 is fixed to the support base 6.2.1 by fasteners. This buffer mechanism 6 effectively absorbs vibrations from the storage box 5. Simultaneously, a receiving box 9 is placed on the sliding plate 8 of the conveying mechanism 7. When the conveying mechanism 7 moves the sliding plate 8 to the screening position 3, the receiving box 9 receives the quartz sand falling from the screening hole 5.1.
