Description

Technical Field

[0001] This utility model relates to the field of steel ball production technology, specifically a steel ball screening mechanism. Background Technology

[0002] Steel ball production is the process of turning steel into steel balls of different specifications through a series of processing techniques. It is widely used in bearings, grinding, forging and other fields. Steel ball production usually includes processes such as raw material preparation, forming, heat treatment, surface treatment, screening and packaging. Screening is generally after heat treatment or surface treatment and is the core quality control link before the finished product leaves the factory.

[0003] Steel ball screening is a process of screening steel balls using screening equipment. The screen is vibrated by a motor, and the steel balls jump on the screen surface. Steel balls smaller than the screen holes fall down to complete the screening.

[0004] In traditional steel ball screening mechanisms, columnar waste materials can easily get stuck inside the screen holes during use, clogging them and affecting screening efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a steel ball screening mechanism to solve the problem of screen hole blockage and its impact on screening efficiency mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel ball screening mechanism, including a base and a screening box, and further including a push-out structure for pushing out columnar waste;

[0007] The ejection structure includes a servo motor, which is installed at the rear end of one side of the screening box. A synchronous wheel is installed at the output end of the servo motor. Two adjustment slots are opened at the bottom of the screening box. A bidirectional threaded rod is rotatably installed on the side of the adjustment slot away from the servo motor. Threaded blocks are fitted on the two opposite parts of the outer wall of the bidirectional threaded rod. The top of each threaded block is connected to a movable rod through a hinge key. Telescopic support rods are installed on both sides of the bottom of the screening box. A base plate is installed at the top of the telescopic support rods.

[0008] The base and the screening box are connected to each other by rubber support blocks, and a vibration motor is installed at the bottom of the front end of the screening box. A discharge port is installed on one side of the front end of the screening box, and a screen is installed at the top of the screening box.

[0009] Preferably, one end of each bidirectional threaded rod passes through the screening box, and one end of each bidirectional threaded rod extends to the outside of the screening box.

[0010] Preferably, one end of each of the bidirectional threaded rods is connected to a synchronous pulley, and the two bidirectional threaded rods can be driven to rotate simultaneously by a servo motor.

[0011] Preferably, the top ends of the movable rods all extend to the bottom end of the base plate, and the movable rods are all connected to the bottom end of the base plate by hinge keys.

[0012] Preferably, the discharge port is connected to the screening box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By controlling the rotation direction of the bidirectional threaded rod with a servo motor, the threaded blocks move towards each other on the outer wall of the bidirectional threaded rod. The threaded blocks push the movable rod, which in turn pushes the bottom plate, causing the bottom plate to rise and drive the telescopic support rod to extend. The columnar waste material inserted into the screening box can be pushed out through the bottom plate. This structure, by raising the bottom plate, pushes out the columnar waste material inside the screening box, preventing the columnar waste material from clogging the screening holes and affecting the screening effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-4 A steel ball screening mechanism includes a base 1 and a screening box 6, and also includes an ejection structure for pushing out columnar waste.

[0021] The ejection structure includes a servo motor 5, which is installed at the rear end of one side of the screening box 6. The output end of the servo motor 5 is equipped with a synchronous wheel 4. Two adjustment slots 9 are opened at the bottom inside the screening box 6. A bidirectional threaded rod 10 is rotatably installed on the side of the adjustment slot 9 away from the servo motor 5. The two reverse-threaded parts of the outer wall of the bidirectional threaded rod 10 are fitted with threaded blocks 12. The top of each threaded block 12 is connected to a movable rod 13 by a hinge key. Telescopic support rods 14 are installed on both sides of the bottom inside the screening box 6. A base plate 11 is installed at the top of the telescopic support rod 14.

[0022] Specifically, such as Figure 1 and Figure 2 As shown, the base 1 and the screening box 6 are connected to each other by a rubber support block 3. A vibration motor 2 is installed at the bottom of the front end of the screening box 6, a discharge port 8 is installed on one side of the front end of the screening box 6, and a screen 7 is installed at the top of the screening box 6. When in use, since the base 1 and the screening box 6 are connected by a rubber support block 3, the vibration motor 2 can drive the screening box 6 to vibrate as a whole. Small steel balls can fall into the interior of the screening box 6 through the holes opened in the screen 7.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one end of each bidirectional threaded rod 10 passes through the screening box 6, and one end of each bidirectional threaded rod 10 extends to the outside of the screening box 6.

[0024] One end of each bidirectional threaded rod 10 is connected to the synchronous wheel 4. The servo motor 5 can drive the two bidirectional threaded rods 10 to rotate simultaneously. When in use, the servo motor 5 is started and driven by the synchronous wheel 4 to rotate the bidirectional threaded rod 10. The rotation direction of the bidirectional threaded rod 10 is controlled by the servo motor 5, so that the threaded block 12 moves towards each other on the outer wall of the bidirectional threaded rod 10.

[0025] Specifically, such as Figure 3 As shown, the top of each movable rod 13 extends to the bottom of the base plate 11, and each movable rod 13 is connected to the bottom of the base plate 11 by a hinge key. In use, the movable rod 13 is pushed by the threaded block 12, which pushes the base plate 11, causing the base plate 11 to rise and drive the telescopic support rod 14 to extend. The columnar waste material inserted into the screening box 6 can be pushed out through the base plate 11.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 The discharge port 8 shown is connected to the screening box 6. When in use, place the container below the discharge port 8 and discharge the steel balls from the discharge port 8 for collection.

[0027] Working principle: The operator places the material to be screened on top of the screen 7, and then starts the vibrating motor 2. Since the base 1 and the screening box 6 are connected by a rubber support block 3, the vibrating motor 2 can drive the entire screening box 6 to vibrate. Small steel balls can fall into the screening box 6 through the holes in the screen 7 and then be discharged through the discharge port 8. Columnar waste remains at the top of the screen 7 and can be discharged through the opening above. If columnar waste gets stuck in the holes of the screen 7 during the screening process, causing a blockage, the operator can adjust the servo motor... When motor 5 starts, it drives the bidirectional threaded rod 10 to rotate via synchronous pulley 4. The rotation direction of the bidirectional threaded rod 10 is controlled by servo motor 5, causing threaded blocks 12 to move closer to each other on the outer wall of the bidirectional threaded rod 10. The threaded blocks 12 push the movable rod 13, which in turn pushes the base plate 11, causing the base plate 11 to rise and extend the telescopic support rod 14. The columnar waste material inserted into the screening box 6 can then be pushed out through the base plate 11. After use, the servo motor 5 can drive the bidirectional threaded rod 10 to rotate in the opposite direction, allowing the base plate 11 to return to its original state.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
