Through the cooperative matching of the components, the high-efficiency and stable steel ball feeding process is realized.

The main body structure of the quick bead changing mechanism consists of a support frame 2 and a storage bin 1, wherein the storage bin 1 and the support frame 2 are connected through rotation to realize relative rotation. The inside of the stock bin 1 is provided with a plurality of partition plates 3, and the partition plates 3 divide the stock bin 1 into a plurality of independent accommodating cavities, and each accommodating cavity is used for storing steel balls with a specific size. In practical application, operators load steel balls with different sizes into each accommodating cavity in advance according to production requirements. The top of the stock bin 1 is provided with an openable top cover, so that the steel balls can be conveniently supplemented or replaced. The observation window 4 has been seted up to annular array on the side panel beating of feed bin 1, and the quantity and the position of observation window 4 pass through reasonable design, ensure that operating personnel can follow the inside steel ball's of a plurality of angles real time monitoring feed bin state. In addition, the inside of the stock bin 1 is also provided with a transparent plate 7 in a sliding manner, and the transparent plate 7 is installed and detached through a handle 6 fixed at the top. The bottom of the handle 6 upwards extends to form a clamping groove, and the design of the clamping groove enables the handle 6 to be firmly buckled to the top of the side sheet metal of the storage bin 1. The presence of the transparent plate 7 not only further enhances the visibility inside the silo, but also allows for easy removal for cleaning or maintenance when needed.

The top of the supporting frame 2 is fixedly provided with a chassis 9, and the chassis 9 and a turntable 8 in the stock bin 1 are connected through rotation to realize synchronous rotation. The turntable 8 is provided with a plurality of blanking holes 10 with different diameters, and the positions and the sizes of the blanking holes 10 are in one-to-one correspondence with the blanking holes 10 on the chassis 9. A plurality of blanking holes 10 with the number and the size matched with those of the turntable 8 are formed in one half side of the chassis 9, and the blanking holes 10 are not formed in the other half side. When the bin 1 rotates to a specific position, a certain blanking hole 10 on the rotary table 8 is overlapped with a corresponding blanking hole 10 on the chassis 9, so that steel balls in a containing cavity corresponding to the blanking hole 10 are allowed to smoothly pass through and enter a subsequent blanking pipe 15. In order to ensure accurate correspondence between the blanking holes 10, the rotation angle of the bin 1 is strictly controlled, and accurate positioning can be achieved through an external controller or manual adjustment.

An eccentric drive assembly is mounted on one side of the support frame 2, and the core components of the assembly include an eccentric motor 12, a transition disc 13 and a rolling bearing 14. The eccentric motor 12 is fixedly arranged on the support frame 2, and the output end of the eccentric motor is rotationally connected with the transition disc 13. The other side of the transition disc 13 is hinged with a rolling bearing 14, and the rolling bearing 14 and the transition disc 13 are arranged in a non-coaxial way. One end of the rolling bearing 14 is slidably arranged in a sliding groove 5 formed in one side of the positioning block 11, and the sliding groove 5 is designed so that the rolling bearing 14 can move along a preset track in the groove. When the eccentric motor 12 is started, the transition disc 13 rotates along with the eccentric motor, and then the rolling bearing 14 is driven to move up and down along the sliding groove 5. This movement converts the rotational movement of the eccentric motor 12 into a linear lifting movement of the positioning block 11. A plurality of blanking pipes 15 are arranged on one side of the positioning block 11, and the top tail ends of the blanking pipes 15 penetrate through blanking holes 10 on the chassis 9, so that the blanking pipes 15 are separated from or contacted with the chassis 9 in the lifting process of the positioning block 11.

The blanking pipe 15 penetrates the guide block 16 and is slidably connected with the guide block 16, and the design of the guide block 16 effectively prevents the blanking pipe 15 from unnecessarily shaking or shifting in the lifting process. The inner wall of the guide block 16 is precision machined to ensure a tight but non-slip fit with the down pipe 15. This structural design significantly improves the operational accuracy of the blanking pipe 15, while at the same time extending the service life of the apparatus.

The operation principle of the quick bead changing mechanism is that S1 an operator selects steel balls with target sizes according to production requirements, and the corresponding accommodating cavity is positioned above the blanking hole 10 of the rotary table 8 by rotating the stock bin 1. S2, when the bin 1 rotates in place, the blanking hole 10 on the rotary table 8 is completely overlapped with the blanking hole 10 on the chassis 9, and steel balls with corresponding sizes start to enter the blanking pipe 15 through the blanking hole 10. And S3, at the same time, starting the eccentric driving assembly, and driving the transition disc 13 to rotate by the eccentric motor 12 so as to push the positioning block 11 to descend through the rolling bearing 14. And S4, in the descending process of the positioning block 11, the top of the blanking pipe 15 is in butt joint with the blanking hole 10 of the chassis 9 again, and the steel balls can smoothly enter the next working procedure through the blanking pipe 15. S5, after one-time feeding is completed, the eccentric driving assembly reversely operates to drive the positioning block 11 to ascend, so that the top of the blanking pipe 15 and the bottom wall of the rotary table 8 keep a certain gap, and friction between the top and the bottom wall is avoided. S6, if the steel balls are required to be switched to steel balls with other sizes, repeating the steps, and adjusting the position of the accommodating cavity by rotating the storage bin 1.

In the practical application scene, the quick bead changing mechanism is widely applied to an automatic production line, and particularly has excellent performance in a multi-specification steel ball processing or assembling link. For example, in the manufacturing process of automobile parts, different types of bearings need to use steel balls with different sizes, and the traditional single-specification feeding mechanism cannot meet the requirement of rapid switching. By arranging a plurality of accommodating cavities and the rotatable turntable 8, steel balls with different sizes can be rapidly switched, and the production efficiency is remarkably improved. In addition, the design of the observation window 4 and the transparent plate 7 enables operators to grasp the state of steel balls in the storage bin at any time, and supplement or replace the steel balls in time, so that production interruption caused by material shortage is avoided.

In conclusion, the quick switching and feeding of steel balls with different sizes is realized through reasonable structural design and accurate motion control. The high-efficiency and stable steel ball feeding system is formed by the multiple accommodating cavities in the storage bin 1, the design of blanking holes 10 of the rotary table 8 and the chassis 9, the matching of the eccentric driving component and the positioning block 11 and the limiting function of the guide block 16. The addition of the transparent plate 7 and the viewing window 4 further promotes the operational convenience and practicality of the apparatus. Through the optimized layout and cooperative coordination of the components, the utility model obviously improves the functional deficiency of the traditional steel ball feeding mechanism and provides a more reliable solution for the production in the related field.
