Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a steel ball processing screening device that prevents crushing. Background Technology

[0002] Steel balls are classified according to their manufacturing process into grinding steel balls, forging steel balls, and casting steel balls. They are also classified according to their materials into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, and alloy balls. Among them, bearing steel balls are important basic components in industry. Alloy steel balls are spherical iron alloy wear-resistant bodies made of carbon, chromium, manganese, molybdenum, and other main added metal elements, produced through forging, spinning, rolling, and casting. They are the most important components in today's crushing industry, mining, and cement industries. During the manufacturing process, steel balls of different diameters inevitably mix together, for example, due to human error, resulting in steel balls from different batches being mixed together.

[0003] Chinese Patent Publication No. CN215031028U discloses a screening device for steel ball processing, which includes a lifting mechanism, a feeding mechanism, a feeding cylinder, and a screen. The lifting mechanism includes support columns, with a support plate between the support columns. The support plate is driven to rise and fall by a first cylinder, and a feeding cylinder is located on the side of the support columns. The feeding mechanism includes a fixed rod, a lifting rod, and a feeding plate. An mounting plate connects the feeding cylinder and the support columns. The fixed rod and the lifting rod are mounted on the mounting plate. The bottom of the lifting rod is connected to a second cylinder, and the tops of the fixed rod and the lifting rod are movably connected to both ends of the feeding plate, respectively. A screen is located below the outlet of the feeding cylinder. The screen is movably suspended below the frame and is driven to swing by a cam. A collection frame is located below one end of the screen. The beneficial effects of this utility model are: the collection cylinder containing the steel balls is raised by the lifting mechanism and pushed onto the feeding mechanism, becoming inclined, allowing the steel balls to fall directly into the feeding cylinder, making the feeding of steel balls more convenient; even when the amount of steel balls is large, they can still be fully screened.

[0004] The existing technical solutions described above have the following shortcomings: During the operation of the steel ball processing and screening device, the steel balls undergo multiple rolling, collisions, and screenings. The above technical solutions do not have a certain anti-smashing mechanism, which may cause the steel balls to jump out of the screening device due to collisions, posing a safety hazard to the surrounding operators and equipment. At the same time, the mutual collisions between steel balls may also damage the screening device itself, affecting the screening efficiency and accuracy. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a steel ball processing and screening device that is designed to prevent crushing, so as to solve the problem mentioned in the background art that the existing steel ball processing and screening devices do not have a crush-proof structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel ball processing and screening device for preventing smashing, comprising a base and a first telescopic rod, wherein the first telescopic rod is fixed at both ends of the top of the base;

[0007] The top of the base is uniformly provided with ball collecting boxes, the top of the first telescopic rod is fixed with a screening frame, one end of the top of the screening frame is provided with a feeding box, one side of the feeding box is fixedly connected to a servo motor through a support plate, and the output shaft end of the servo motor is fixed with a connecting rod, the outside of the connecting rod is uniformly sleeved with rotating blades, and the inside of the screening frame is uniformly provided with screening grooves.

[0008] Preferably, a storage slot is provided on one side of the screening frame, and an anti-smashing plate is provided inside the storage slot. The two ends of the bottom of the anti-smashing plate are movably connected to connecting rods through hinge seats, and telescopic springs are movably connected between the connecting rods through movable seats. A telescopic sleeve is fixed at the bottom of the connecting rod.

[0009] Preferably, damping sleeves are fixed at both ends of the bottom of the ball collecting box, and a fixing block is fixed on the base of one side of the damping sleeve.

[0010] Preferably, the fixed block has a rubber sleeve inside, and a movable block is fixed to one side of the rubber sleeve. The movable block and the ball collecting box are movably connected by a movable rod through a fixed seat.

[0011] Preferably, the ball collecting box is provided with an anti-collision plate inside, the bottom of the anti-collision plate is uniformly fixed with movable springs, and sliders are fixed on both sides of the anti-collision plate. Slide grooves are provided on both sides of the inside of the ball collecting box, and the dimensions between the sliders and the slide grooves are matched.

[0012] Preferably, the top of the feeding box is provided with an opening, and the bottom of the feeding box is provided with discharge ports evenly distributed.

[0013] Preferably, there are four sieving troughs in total, and each sieving trough consists of three different widths of separating troughs.

[0014] Preferably, there are two first telescopic rods, and the two first telescopic rods are of different sizes.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the anti-smashing steel ball processing and screening device facilitates the screening of steel balls, improves the efficiency of the screening device, and the anti-smashing structure reduces the impact of steel balls on the device itself and the mutual impact between steel balls, thus extending the service life of the screening device.

[0016] By setting up anti-smashing plates, connecting rods, telescopic sleeves, and telescopic springs, they work together. When the anti-smashing plate is impacted by a steel ball, the telescopic spring will undergo elastic deformation, thereby absorbing the impact energy. The telescopic sleeve will then work in conjunction with this to extend and retract, balancing the energy and protecting the storage tank from damage. This effectively reduces the impact force of falling steel balls, thereby preventing damage to the screening device and improving the anti-smashing performance of the screening device.

[0017] By setting up a ball collecting box, a fixed block, a damping sleeve, and a movable rod, when a steel ball falls into the ball collecting box, the anti-collision plate is subjected to external force, causing the movable spring to deform. Simultaneously, the slider slides and supports itself inside the groove. Even if the steel ball falls onto the anti-collision plate, it avoids damage to the bottom of the ball collecting box due to large impact force, thus playing a role in preventing smashing. Then, when the ball collecting box is subjected to the impact force generated by multiple steel balls, the rubber sleeve, the movable block, and the movable rod work together to buffer and release the impact force. When the ball collecting box is subjected to external force, the movable rods open and close, causing the movable block to move. This causes the rubber sleeve to compress and deform, thereby reducing the impact and vibration of external force on the ball collecting box, improving the anti-smashing performance, reducing safety hazards, and extending the service life of the steel ball processing and screening device.

[0018] By activating the servo motor, the connecting rod and rotating blades are driven to rotate, which facilitates the uniform feeding of steel balls of different diameters. This allows the steel balls to enter the steel ball processing and screening device in a stable and continuous manner, thereby maintaining the smooth operation of the production process and improving the efficiency of the screening device.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] Example 1

[0030] To address the lack of impact-resistant performance in existing steel ball processing and screening devices, the following solution is disclosed. Please refer to the details below. Figure 1 , Figure 2 , Figure 4 , Figure 6A steel ball processing and screening device with anti-smashing features includes a base 1 and a first telescopic rod 2. The first telescopic rod 2 is fixed to both ends of the top of the base 1. A ball collecting box 3 is evenly distributed on the top of the base 1. A screening frame 4 is fixed to the top of the first telescopic rod 2. A storage groove 401 is provided on one side of the screening frame 4, and an anti-smashing plate 10 is installed inside the storage groove 401. The bottom ends of the anti-smashing plate 10 are movably connected to connecting rods 11 via hinged seats, and telescopic springs 13 are movably connected between the connecting rods 11 via movable seats. A telescopic sleeve 12 is fixed to the bottom of the connecting rods 11. Damping sleeves 15 are fixed to both ends of the bottom of the ball collecting box 3. The base is connected to one side of the damping sleeve 15. (1) A fixed block 14 is fixed on the top. A rubber sleeve 1401 is provided inside the fixed block 14. A movable block 1402 is fixed on one side of the rubber sleeve 1401. A movable rod 16 is movably connected between the movable block 1402 and the ball collecting box 3 through a fixed seat. A collision protection plate 301 is provided inside the ball collecting box 3. Movable springs 302 are evenly fixed at the bottom of the collision protection plate 301. A slider 303 is fixed on both sides of the collision protection plate 301. A sliding groove 304 is provided on both sides inside the ball collecting box 3. The dimensions between the slider 303 and the sliding groove 304 are matched. There are two first telescopic rods 2. The two first telescopic rods 2 are different in size.

[0031] In this embodiment, during use, different first telescopic rods 2 are used to tilt the screening frame 4, facilitating the screening of steel balls. When a steel ball falls into the ball collecting box 3, the anti-collision plate 301 is subjected to external force, causing the movable spring 302 to deform. Simultaneously, the slider 303 slides and supports itself inside the slide groove 304. Even if a steel ball falls onto the anti-collision plate 301, it avoids damage to the bottom of the ball collecting box 3 from a large impact, thus preventing it from being smashed. Then, when the ball collecting box 3 is subjected to the impact force generated by multiple steel balls, the rubber collar 1401, the moving block 1402, and the movable rod 16 work together to buffer and release the impact force. When subjected to external force, the movable rod 16 opens and closes, causing the movable rod 16 to move the moving block 1402, which in turn compresses and deforms the rubber sleeve 1401, thereby reducing the impact and vibration of the external force on the ball collecting box 3, improving the anti-smashing performance, reducing safety hazards, and increasing the service life of the steel ball processing and screening device. When the anti-smashing plate 10 is impacted by a steel ball, the telescopic spring 13 will undergo elastic deformation, which will absorb the impact energy, allowing the telescopic sleeve 12 to cooperate with it and perform telescopic movement, thus balancing the energy and protecting the storage tank 401 from damage. This effectively reduces the impact force of falling steel balls, thereby preventing damage to the screening device and improving the anti-smashing performance of the screening device.

[0032] Example 2

[0033] This embodiment differs from Embodiment 1 in that it utilizes the sieving groove 9 to sieve steel balls of different diameters, thereby improving the efficiency of the steel ball processing sieving device. Therefore, the following technical solution is disclosed; please refer to the details. Figure 1 , Figure 3 , Figure 5 The top end of the screening frame 4 is provided with a feeding box 5. A servo motor 6 is fixedly connected to one side of the feeding box 5 through a support plate, and a connecting rod 7 is fixed to the output shaft end of the servo motor 6. Rotating blades 8 are uniformly sleeved on the outside of the connecting rod 7. Screening grooves 9 are uniformly arranged inside the screening frame 4. An opening 501 is provided at the top of the feeding box 5, and a discharge port 502 is uniformly arranged at the bottom of the feeding box 5. There are four screening grooves 9 in total, and each screening groove 9 is composed of three different widths of dividing grooves.

[0034] In this embodiment, during use, steel balls of different diameters are conveyed into the feed box 5 through the opening 501. The servo motor 6 is started, causing the connecting rod 7 and the rotating blade 8 to rotate. This allows the steel balls to fall into the screening trough 9 through the discharge port 502, ensuring that the steel balls enter the steel ball processing and screening device in a stable and continuous manner. This maintains the smooth operation of the production process and improves the efficiency of the screening device. The screening trough 9 consists of three different widths of separating grooves, allowing steel balls of different diameters to fall into different ball collection boxes 3 through the different separating grooves on the screening trough 9. This effectively improves the accuracy of sorting. By utilizing the weight of the steel balls themselves, the rolling screening reduces labor intensity and improves the efficiency of the steel ball processing and screening device.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
