[0002] The screw grinder generally adopts the ball milling mode to polish the screw, and the screw and the grinding ball are mixed together after grinding, so it is not easy to pick out, and therefore the screening equipment is needed for screening.

[0003] The existing screening equipment pours the mixed material on the filter screen, and shakes manually for filtering, the efficiency is low, and the filter screen is blocked in the filtering process. UTILITARIAN CONTENT

[0004] In order to overcome the ball milling of the screw, the existing separation process is manually, but the screening efficiency is low, the utility model provides a screening device for screw grinding.

[0005] The technical scheme of the utility model is: a screening device for screw grinding, including screening box, filter screen, the filter screen is arranged in the screening box, further including motor, connecting rod, rotating ring and sliding block, the motor is connected at the bottom of the screening box, the output shaft of the motor is connected with the connecting rod, the connecting rod is connected with the rotating ring, the rotating ring is rotatably connected to the inner side of the screening box, the wave-shaped sliding groove is formed in the rotating ring, the sliding block is arranged on the side surface of the filter screen, the sliding block is limited to slide in the wave-shaped sliding groove, the motor is started to drive the rotating ring to rotate through the connecting rod, the wave-shaped sliding groove formed in the rotating ring drives the sliding block to move up and down, so as to drive the filter screen to move up and down.

[0006] Further, it further includes a transmission shaft, a scraper and a spline, the spline is arranged on the upper end of the connecting rod, the transmission shaft is slidably connected to the spline, the transmission shaft is connected with the scraper, and the scraper can be in frictional contact with the filter screen.

[0007] Further, it further includes a flow guide cover, the bottom of the screening box is provided with an arc-shaped flow guide cover, and the flow guide cover covers the outside of the motor.

[0008] Further, it further includes a flow guide pipe, and the bottom of the screening box is connected with the flow guide pipe.

[0009] Further, it further includes an adjusting foot, and the bottom of the screening box is provided with the adjusting foot.

[0010] Further, it further includes a cover and a handle, the top of the screening box is provided with the cover, and the side surface of the screening box is connected with the handle.

[0011] The beneficial effects are: 1. When the motor is turned on, the rotating ring rotates continuously. The wave-shaped groove on the rotating ring drives the slider to move up and down, thereby driving the filter screen to move up and down. The up and down movement of the filter screen creates continuous vibration, which improves the pass rate and screening rate of the mixture of screws and grinding balls in the filter screen.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] Example: A sieving device for screw grinding, such as Figs. 1-3 As shown, the system includes a screening box 1 and a filter screen 5. The top of the screening box 1 is equipped with a cover 13, and a handle 14 is connected to the side of the screening box 1. A guide pipe 11 is connected to the bottom of the screening box 1, and an adjusting foot 12 is provided at the bottom of the screening box 1. The filter screen 5 is installed inside the screening box 1. The system also includes a motor 2, a connecting rod 3, a rotating ring 4, and a slider 6. The motor 2 is connected to the bottom of the screening box 1, and the output shaft of the motor 2 is connected to the connecting rod 3. The connecting rod 3 is connected to the rotating ring 4, which is rotatably connected to the inner side of the screening box 1. A wavy groove is provided on the rotating ring 4. A slider 6 is provided on the side of the filter screen 5. The slider 6 slides within the wavy groove. When the motor 2 is turned on, it drives the rotating ring 4 to rotate through the connecting rod 3. The wavy groove on the rotating ring 4 drives the slider 6 to move up and down, thereby moving the filter screen 5 up and down.

[0018] like Fig. 2 As shown, it also includes a drive shaft 7, a scraper 8 and a spline 9. The upper end of the connecting rod 3 is provided with a spline 9. The drive shaft 7 is slidably connected to the spline 9. The drive shaft 7 is connected to the scraper 8, and the scraper 8 can rub against the filter screen 5.

[0019] like Fig. 2 As shown, it also includes a flow guide shroud 10. An arc-shaped flow guide shroud 10 is provided at the bottom of the screening box 1, and the flow guide shroud 10 covers the outside of the motor 2.

[0020] Working principle: after the screw completes the external polishing process of the ball mill, the mixture of the screw and the polishing ball is introduced into the screening box 1, and then the motor 2 is started, the motor 2 drives the rotating ring 4 to rotate continuously through the connecting rod 3, the wave-shaped sliding groove of the rotating ring 4 drives the sliding block 6 to move up and down, so as to drive the filter screen 5 to move up and down, the continuous vibration is formed by the up and down movement of the filter screen 5, the passing rate and the screening rate of the mixture of the screw and the polishing ball on the filter screen 5 are improved, at the same time, the scraper 8 is driven to rotate continuously through the transmission shaft 7, the scraper 8 can push and stir the mixture of the screw and the polishing ball remaining on the filter screen 5, and the screening efficiency of the screw and the polishing ball is further improved.
