The storage hopper 1 is fixed by a mounting bracket 17 located on the upper part of the base frame 9 .

The feeding chute is located below the outlet of the storage hopper 1 , and is also fixed by the mounting bracket 17 located on the upper part of the base frame 9 . In order to adjust the initial speed when the spherical raw material enters the conical sorting disc 5, the feeding chute is set to be adjustable in inclination. Specifically, the feeding chute is composed of a first feeding chute 3 and a second feeding chute 4 connected by pins, The first trough 3 is connected to the base frame 9 through a combination of screws and nuts, and the inclination of the first trough 3 is achieved by changing the distance between the screws and nuts. In the position of the first trough 3 near the outlet of the storage hopper 1, an inverted "U"-shaped plate is arranged, and the screw passes through the bottom of the "U"-shaped plate or is welded with the bottom of the "U"-shaped plate. It is then connected to the nut above the mounting plate set on the base frame 9; while the second trough 4 extends to the top of the conical sorting disc 5, and the outlet direction is the same as the circumference of a certain diameter on the sorting disc. Tangentially or slightly outwards, so that the material leaves the second trough 4 and then performs a circular motion.

In order to adjust the feeding speed, a flow switch 2 is also arranged in this embodiment, and the flow switch 2 is arranged on the first material trough 3 of the unloading trough.

The conical sorting disc 5 is in the shape of a funnel, specifically a conical surface with a part of the tip cut off by a plane parallel to the bottom surface, and in order to ensure that the material does not fly out after entering the conical sorting disc 5, a material fence 18 is also provided, The fence 18 is arranged on the outer edge of the conical sorting disc 5 .

There is a notch groove 23 on the baffle ring, which is located on the opening of the upper edge of the finished barrel 10, and the baffle ring is not in contact with the conical sorting disc 5, so that the qualified spherical material can fly into the finished barrel 10, and the unqualified material can fly into the finished barrel 10. The material does not fly through the gap between the baffle ring and the outlet of the conical sorting disc 5 at a sufficient speed.

The rotary bearing 6 is fixed under the conical sorting disc 5 and is located outside the waste bucket 13; and the shaft sleeve 15 is sleeved on the outside of the rotary bearing 6 and fixed on the shaft sleeve mounting plate 7; the shaft sleeve installation plate 7 is arranged on the base frame On the body 9; the driving motor 14 is installed on the bushing mounting plate 7, and is connected with the rotary bearing 6, therefore, the conical sorting disc 5 can be driven to rotate through the rotary bearing 6, so that the conical sorting disc 5 enters the The accumulation of materials that are difficult to roll by themselves, such as special-shaped objects and powders, blocks the movement of the qualified balls. At the same time, these unqualified large materials will also fall into the waste bucket 13 due to their own gravity during the rotation process. Still further, in order to prevent large materials from falling into the notch groove 23, a cleaning plate 22 with an adjustable position is provided after the exit of the feeding trough and before the notch groove 23, and a mounting arm is provided on the base frame for installation. The arm is pinned with a first connecting rod, the connecting rod is connected with the cleaning plate 22, the lower end of the cleaning plate 22 is against the upper surface wall of the conical sorting plate 5, and only one end is provided with the conical sorting plate 5. The edge of the discharge port is flush to leave a channel for the roundness of the ball to pass.

In addition, in order to clean the deformed materials that are attached to the conical sorting disc 5 and cannot be removed by the cleaning plate 22, after passing through the notch groove 23 and before reaching the outlet of the unloading chute, a position-adjustable waste material is also provided. The scraper 21 stops the ball from moving forward and falls into the waste bucket 13. The scrap scraper 21 passes through the second connecting rod pinned on the mounting arm, and the connecting rod is pin-connected to the scrap scraper 21; The scrap scraper 21 is arranged on the frame body, its lower end is against the upper surface wall of the conical sorting disc 5, one end is flush with the edge of the discharge port of the conical sorting disc 5, and the other end is flush with the conical sorting disc 5 The outer edges of the 5 are flush.

Further, in order to make this machine applicable to the spherical material range, a disc selection inclination adjustment device is also provided; It is fixed on one end of the bushing mounting plate 7 , and the other end of the bushing mounting plate 7 is connected with the base frame 9 by pins.

working principle

After the ball comes out of the storage hopper 1, due to the small friction between the ball with good roundness and the feeding chute, the initial speed when rolling out of the feeding chute is faster than the speed of the irregularly shaped material; the material leaves the second feeding chute. 4 After entering the conical sorting disc 5, the material will have its own gravity and a certain initial speed, and the material will move in a circular motion along the direction of the discharge chute and in the downward direction along the surface of the conical sorting disc 5. , therefore, the movement trajectory of the material will be curved, and the initial velocity of the irregular material will be slower, and the frictional force on the conical sorting disc 5 will be greater, and the initial velocity will also decay faster, making its trajectory shorter than the qualified sphere The material finally falls into the waste bucket 13 under the action of the cleaning plate 22; therefore, the automatic separation of the spherical sphere, the ellipsoidal sphere and the special-shaped sphere during rolling is the result of the speed difference and the different running trajectories. When the ball rolls up, centrifugal force is generated under the action of the initial speed, so that the ball moves down to the center of the conical sorting disk 5 more slowly than the special-shaped ball. Specifically, after the ball enters the conical sorting disk 5, It rolls along the middle and outer edges of the sorting tray in an arc, and passes over the cleaning plate 22 , and then rolls into the notch groove 23 .

Only the balls with qualified roundness will reach the position of the notch groove 23 along the preset curved trajectory, and due to the downward separation speed along the conical sorting plate 5, the balls will fly over the baffle plate 16 and the conical sorting The gap between the outlet of the disc 5 falls into the finished barrel 10, and the elliptical and special-shaped spheres have different running trajectories when rolling, and the initial speed is difficult to maintain a circular motion for a long enough time. It falls into the waste box during operation. In addition, some powders or materials with special deformities will adhere to the materials on the upper surface of the conical sorting disc 5 as soon as they enter or move for a short distance, even if they are not cleaned by the cleaning plate 22. Cleaned up by scrap scraper 21.

For spherical materials of different materials, the inclination of the feeding chute and the conical sorting disc 5 can be adjusted before use.

The above embodiment only represents an embodiment of the present invention, and its description is more specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be pointed out that for those of ordinary skill in the art, some modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for this utility model shall be subject to the appended claims.
