Description

Technical Field

[0001] The utility model relates to the technical field of steel ball processing, in particular to a steel ball screening device. Background Art

[0002] Steel ball processing is a precision manufacturing process that involves multiple steps, including raw material preparation, cutting and forming, rough and fine grinding, and heat treatment, to transform steel into steel balls with high precision and good performance. Different application scenarios have very strict requirements on the size of steel balls. Through screening, steel balls that do not meet the size standards can be screened out to ensure the dimensional consistency of the final product. For example, the steel balls used in high-precision mechanical bearings have extremely small dimensional deviations, and screening can effectively guarantee this requirement.

[0003] However, the prior art still has the following problems:

[0004] First of all, most of the steel ball screening devices in the existing technology have low screening efficiency. Traditional steel ball screening devices may rely mainly on manual operation for screening, which is not only slow but also prone to fatigue and errors, resulting in low screening efficiency and requiring frequent manual intervention and adjustment, consuming a lot of time and manpower.

[0005] Secondly, the steel ball screening device in the existing technology may not have an effective buffer and guide structure in the collection structure. The steel balls are prone to collision, bounce and chaotic distribution when falling into the collection box, affecting the orderliness and accuracy of the collection. In addition, the collection box of some existing devices may not be able to effectively prevent the steel balls from falling when it is in a specific position (such as above), causing the steel balls to fall or scatter, affecting the collection effect and screening efficiency.

[0006] In response to the above problems, the inventors proposed a steel ball screening device to solve the above problems. Utility Model Content

[0007] In order to solve the problem of low screening efficiency and the problem that effective buffering and guiding structures may not be provided in the collection structure, the purpose of the utility model is to provide a steel ball screening device.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions: a steel ball screening device, comprising a base plate, a vertical plate is fixedly provided on one side of the upper end of the base plate, a motor is provided at one end of the vertical plate, the output end of the motor passes through the vertical plate and is fixedly provided with a screening drum, one end of the screening drum is rotatably connected to the vertical plate, a plurality of collecting boxes are provided on the outer surface of the screening drum, a plurality of fixed blocks are fixedly provided on the outer surface of the screening drum, and two corresponding fixed blocks are connected to the corresponding collecting boxes by bolts, a mounting frame is fixedly provided at one end of the collecting box, a plurality of mounting grooves for cooperating with the mounting frame are opened on the outer surface of the screening drum, a screening plate is fixedly provided on the inner surface of the mounting frame, a feed elbow is provided at a height on one side of the upper end of the base plate, and a feed hopper is fixedly provided on the upper end of the feed elbow.

[0009] Preferably, the upper end of the screening plate is provided with a plurality of through-type screening slots, and the sizes of the screening slots on different screening plates are different. Baffles are fixedly provided on the inner walls on both sides of the collecting box, and one end of the opposite surfaces of the two baffles are movably contacted with a rotating plate. Connecting blocks are fixedly provided on both sides of the upper end of the rotating plate and the baffle, and the two corresponding connecting blocks on one side are rotatably connected, that is, the rotating plate can be rotated on the inner side of the upper end of the baffle.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model realizes automatic screening of steel balls by rotating the screening drum through the motor, which improves the screening efficiency. Compared with the traditional manual screening, it greatly saves time and labor costs. In addition, the screening mechanism can be replaced according to different size requirements, which makes it more versatile.

[0012] 2. The utility model plays a buffering and guiding role through the baffle and rotating plate in the collection box. The steel balls are distributed more orderly in the collection box when collected. When the collection box is located at the upper part, the rotating plate cooperates with the baffle to block the steel balls to prevent them from falling, thereby improving the collection effect of the collection box and enhancing the efficiency and stability of screening.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Figure 1-2As shown, the utility model provides a steel ball screening device, including a base plate 1, a vertical plate 2 is fixedly provided on one side of the upper end of the base plate 1, one end of the vertical plate 2 is provided with a motor 21, the lower end of the motor 21 is connected to a support plate 22 by bolts, one end of the support plate 22 is fixedly connected to the vertical plate 2, the output end of the motor 21 passes through the vertical plate 2 and is fixedly provided with a screening drum 3, one end of the screening drum 3 is fixedly provided with two limiting columns 23, and one end of the vertical plate 2 is provided with a limiting ring groove 24 for cooperating with the limiting columns 23, the outer surface of the screening drum 3 is provided with a plurality of collecting boxes 6, one end of the collecting box 6 is fixedly provided with a mounting frame 51, the outer surface of the screening drum 3 is provided with a plurality of mounting grooves 53 for cooperating with the mounting frame 51, the inner surface of the mounting frame 51 is fixedly provided with a screening plate 5, the upper end of the screening plate 5 is provided with a plurality of through-type screening slots, and the screening slots on different screening plates 5 have different sizes. The bottom plate 1 serves as a supporting structure. First, the steel balls to be screened are input into the screening drum 3 through the feed elbow 4. After the motor 21 supported by the support plate 22 on the vertical plate 2 is started, its output end drives the screening drum 3 to rotate. The cooperation of the limiting column 23 and the limiting ring groove 24 ensures the stability of the screening drum 3 during rotation. Since screening plates 5 with screening slots of different sizes are provided on the screening drum 3, during the rotation process, steel balls of different sizes will be screened out according to the size of the screening slot, and smaller steel balls pass through the screening slot and fall into the corresponding collecting box 6. When installing the collecting box 6, the mounting frame 51 is installed in the mounting slot 53, which is convenient for replacing screening mechanisms with different size requirements and has higher versatility. The screening drum 3 is driven to rotate by the motor 21, thereby realizing automatic screening of the steel balls, improving screening efficiency, and greatly saving time and labor costs compared with traditional manual screening.

[0020] A feed elbow 4 is provided at a height on one side of the upper end of the bottom plate 1, and a feed trough 41 is opened at one end of the screening drum 3 for use with the feed elbow 4, and the outer surface of the feed trough 41 is in active contact with the outer surface of the feed elbow 4. The steel balls enter the feed trough 41 of the screening drum 3 through the feed elbow 4, and the feeding is stable, reducing the leakage of steel balls.

[0021] There are four collecting boxes 6, and the four collecting boxes 6 are distributed in a ring shape. A plurality of fixing blocks 52 are fixed on the outer surface of the screening cylinder 3, and two corresponding fixing blocks 52 are connected to the corresponding collecting boxes 6 through bolts. Four sizes of steel balls can be screened at the same time, and the screening effect is high. The collecting box 6 is installed by the bolts on the fixing blocks 52, which is easy to install and relatively firm.

[0022] Example 2: Figure 3As shown, baffles 61 are fixedly provided on the inner walls of both sides of the collecting box 6, and one end of the opposite surfaces of the two baffles 61 are movably in contact with a rotating plate 62, and connecting blocks 63 are fixed on both sides of the upper ends of the rotating plate 62 and the baffle 61, and the two corresponding connecting blocks 63 on one side are rotatably connected. The baffles 61 and the rotating plate 62 in the collecting box 6 play a buffering and guiding role. When the steel balls fall into the collecting box 6, they first contact the rotating plate 62. Through the rotating connection of the connecting block 63, the rotating plate 62 can rotate on the baffle 61, and the steel balls are distributed in the collecting box 6 more orderly. When the collecting box 6 is located at the top, the two rotating plates 62 fall naturally, and cooperate with the baffle 61 to block the steel balls in the collecting box 6 to prevent the steel balls from falling, thereby improving the collection effect of the collecting box 6 and enhancing the efficiency and stability of screening.

[0023] Working principle: the bottom plate 1 serves as a supporting structure. First, the steel balls to be screened are input into the screening drum 3 through the feed elbow 4. After the motor 21 supported by the support plate 22 on the vertical plate 2 is started, its output end drives the screening drum 3 to rotate. The cooperation of the limiting column 23 and the limiting ring groove 24 ensures the stability of the screening drum 3 during rotation. Since the screening plates 5 with screening slots of different sizes are provided on the screening drum 3, during the rotation process, steel balls of different sizes will be screened out according to the size of the screening slot, and the smaller steel balls pass through the screening slot and fall into the corresponding collecting box 6. When installing the collecting box 6, the mounting frame 51 is installed in the mounting slot 53, which is convenient for replacing screening mechanisms with different size requirements and has higher versatility. The screening drum 3 is driven to rotate by the motor 21 to realize automatic screening of the steel balls, thereby improving screening efficiency and greatly saving time and labor costs compared with traditional manual screening.

[0024] The steel balls enter the feed trough 41 of the screening drum 3 through the feed elbow 4, which ensures stable feeding and reduces leakage of steel balls.

[0025] It can screen four sizes of steel balls at the same time, with a high screening effect. The collecting box 6 is installed by the bolts on the fixing block 52, which is easy to install and relatively firm.

[0026] The baffle 61 and the rotating plate 62 in the collecting box 6 play a buffering and guiding role. When the steel balls fall into the collecting box 6, they first contact the rotating plate 62. Through the rotation connection of the connecting block 63, the rotating plate 62 can rotate on the baffle 61, and the steel balls are distributed in the collecting box 6 more orderly. When the collecting box 6 is located at the upper part, the two rotating plates 62 fall down naturally and cooperate with the baffle 61 to block the steel balls in the collecting box 6 to prevent the steel balls from falling, thereby improving the collection effect of the collecting box 6 and enhancing the efficiency and stability of screening.

[0027] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
