[0002] During the cold heading process, steel balls may produce defective blanks. These blanks are damaged balls with notches or unformed cylinders, which need to be removed by a blank screening device.

[0003] According to the search results, the announcement number CN214718420U, entitled "A Multi-stage Rotary Screening Device for Anti-clogging Material in Steel Ball Processing," includes a feeding mechanism, a screening mechanism, and a receiving structure. Through research and analysis, it was found that although the multi-stage rotary screening device for anti-clogging material in steel ball processing has advantages such as uniform and reliable feeding, clean screening without clogging, secondary screening capability, and the ability to remove large steel balls, it also has the following disadvantages to a certain extent.

[0004] For example, the screening components of screening devices are mostly designed in a fixed state, which makes it impossible to adjust the screening opening size for different specifications of steel balls, and cannot adapt to steel ball materials of different sizes and specifications, reducing the flexibility and practicality of the device, resulting in unsatisfactory screening effect. In order to solve the above technical problems, it is necessary to design a steel ball screening adjustment device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a steel ball screening and adjustment device, which has the advantages of ensuring that the steel ball feeding speed meets the requirements, improving the flexibility and practicality of the device, and solving the problem that the screening opening lacks size adjustment function and cannot adapt to steel ball materials of different sizes and specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel ball screening and adjusting device, including a support, a screening cylinder at the top of the support, a material discharge channel welded to the inner cavity of the screening cylinder, a frame within the inner cavity of the screening cylinder, a screen frame placed within the inner cavity of the frame, an adjusting mechanism within the inner cavity of the screening cylinder, the adjusting mechanism including an adjusting plate in contact with the surface of the frame, a cylinder fixedly connected between the frame and the adjusting plate, a motor fixedly connected to the surface of the screening cylinder, a turntable fixedly connected to the shaft of the motor, a guide frame fixedly mounted on the surface of the frame, a guide rod welded to the surface of the turntable, one end of the guide rod extending into the inner cavity of the guide frame and movably connected to the inner wall of the guide frame, a first discharge port and a second discharge port respectively opened on the inner walls of the screen frame and the adjusting plate, a conveyor belt on the opposite side of the support, and a collection box placed on top of the conveyor belt.

[0007] Preferably, the surface of the frame is provided with a slide rail, and the surface of the adjusting plate is welded with a slide block, which is movably sleeved on the surface of the slide rail.

[0008] Preferably, the surface of the frame is rotatably connected to a limiting member via a damping shaft, the limiting member is in contact with the surface of the screen frame, and a handle is welded to the surface of the screen frame.

[0009] Preferably, a cover plate is movably connected to the surface of the screening cylinder via a hinge, and a handle is welded to the surface of the cover plate.

[0010] Preferably, a bearing is movably connected between the motor shaft and the inner wall of the screening cylinder, one side of the bearing is fixedly connected to the inner wall of the screening cylinder, and the bearing is movably sleeved on the surface of the motor shaft.

[0011] Preferably, the inner cavity of the screening cylinder is welded with a crossbar, the surface of the crossbar is movably sleeved on a support sleeve, and the surface of the support sleeve is welded to the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the cooperation of a first discharge port, a second discharge port, a frame, a screen frame, an adjusting plate, a cylinder, a slide rail, and a slide seat, drives the cylinder to extend and retract laterally along the guide trajectory of the slide rail on the slide seat, pressing the adjusting plate to swing laterally. This causes the second discharge port on the surface of the adjusting plate and the first discharge port of the screen frame to intersect each other, allowing the size of the discharge port of the first discharge port to be adjusted and optimized. Different discharge port sizes can be adjusted for different specifications of steel balls to meet the feeding requirements of steel balls of different specifications.

[0014] 2. This utility model uses the cooperation of a motor, turntable, guide frame, guide rod, crossbar and support sleeve to drive the motor to rotate the turntable and use the guide rod to operate along the guide frame's guide trajectory to push the frame to move laterally to generate vibration force. The screen frame is placed in the frame and vibrates repeatedly under the action of the frame, thereby causing the steel balls in the screen frame to vibrate and fall quickly.

[0020] Please see Figures 1-4 The steel ball screening and adjusting device includes a support 1, a screening cylinder 2 on the top of the support 1, a material discharge channel 3 welded to the inner cavity of the screening cylinder 2, a frame 4 in the inner cavity of the screening cylinder 2, a screen frame 5 placed in the inner cavity of the frame 4, an adjusting mechanism 6 in the inner cavity of the screening cylinder 2, the adjusting mechanism 6 including an adjusting plate 7, the adjusting plate 7 contacting the surface of the frame 4, a cylinder 8 fixedly connected between the frame 4 and the adjusting plate 7, a motor 9 fixedly connected to the surface of the screening cylinder 2, a turntable 10 fixedly connected to the shaft of the motor 9, a guide frame 11 fixedly installed on the surface of the frame 4, a guide rod 12 welded to the surface of the turntable 10, one end of the guide rod 12 extending into the inner cavity of the guide frame 11 and movably connected to the inner wall of the guide frame 11, a first discharge port 13 and a second discharge port 14 respectively opened on the inner walls of the screen frame 5 and the adjusting plate 7, a conveyor belt 15 is provided on the opposite side of the support 1, and a collection box 16 is placed on the top of the conveyor belt 15.

[0021] Please see Figure 2 , Figure 3 and Figure 4 The surface of the frame 4 is provided with a slide rail 17. By providing the slide rail 17, the slide block 18 can be moved laterally and guided, so that the adjustment plate 7 can be indirectly connected to the frame 4. The surface of the adjustment plate 7 is welded with a slide block 18, which is movably sleeved on the surface of the slide rail 17.

[0022] Please see Figure 2 The surface of the frame 4 is rotatably connected to the limiting member 19 via a damping shaft. The limiting member 19 contacts the surface of the screen frame 5. A handle is welded to the surface of the screen frame 5. By setting the handle, the flexibility between the user and the screen frame 5 is increased, making it convenient to move the screen frame 5.

[0023] Please see Figure 1 The surface of the screening cylinder 2 is movably connected to a cover plate 20 via a hinge. A handle is welded to the surface of the cover plate 20. By setting the handle, a support point is provided for contact with the cover plate 20, thereby enhancing its practicality.

[0024] Please see Figure 2A bearing is movably connected between the rotating shaft of the motor 9 and the inner wall of the screening cylinder 2. By setting the bearing, a stable connection can be made between the rotating shaft of the motor 9 and the inner wall of the screening cylinder 2, which facilitates the rotation of the rotating shaft of the motor 9. One side of the bearing is fixedly connected to the inner wall of the screening cylinder 2, and the bearing is movably sleeved on the surface of the rotating shaft of the motor 9.

[0025] Please see Figure 3 The inner cavity of the screening cylinder 2 is welded with a crossbar 21. By setting the crossbar 21, the support sleeve 22 can be laterally supported and guided to prevent the frame 4 from deviating from its original trajectory. The surface of the crossbar 21 is movably sleeved on the support sleeve 22, and the surface of the support sleeve 22 is welded to the frame 4.

[0026] In use, the steel balls are placed on top of the screen frame 5 inside the frame 4 for storage. The external controller activates the cylinder 8 to extend and retract, pushing the adjusting plate 7 to move laterally along the slide rail 17 on the surface of the frame 4. The second discharge port 14 on the surface of the adjusting plate 7 maintains a gap with the first discharge port 13 on the surface of the frame 4. This gap between the adjusting plate 7 and the side wall of the first discharge port 13 will increase or decrease, allowing adjustment of the gap according to the production of steel balls of different specifications. The external controller activates the output shaft of the motor 9 to rotate... The rotation of turntable 10 synchronously drives guide rod 12 to move within guide frame 11, generating a pushing force on guide frame 11 and causing frame 4 to swing left and right. Frame 4 uses support sleeve 22 to slide along crossbar 21 to generate vibration force to adjust the discharge amount, thereby ensuring uniform material feeding and appropriate speed. The discharge channel 3 pushes the steel ball to fall into the top collection box 16 of conveyor belt 15, where the steel ball can be collected. The rotating limiter 19 is used to move away from screen frame 5. Holding the handle and pulling screen frame 5 makes it easy to separate screen frame 5 from and place it in the inner cavity of frame 4.

[0027] In summary, this steel ball screening and adjustment device, through the cooperation of the support 1, screening cylinder 2, material discharge channel 3, frame 4, screen frame 5, adjustment mechanism 6, adjustment plate 7, cylinder 8, motor 9, turntable 10, guide frame 11, guide rod 12, first discharge port 13, second discharge port 14, conveyor belt 15, and collection box 16, solves the problem that the screening port lacks size adjustment function and cannot adapt to steel balls of different sizes and specifications.
