Abstract
Description
Technical Field:
[0001] The utility model relates to a screening machine, specifically an efficient fine grinding and screening machine dedicated to the production of polishing powder, belonging to the technical field of screening machines. Background Art:
[0002] At present, the production processes for industrial preparation of polishing powder can be roughly divided into three types: dry method, wet method, and mixed blending type. Among them, the production of polishing powder by mixed blending is a common industrial production process. This production method is simpler, and the obtained products are more suitable for the demanding manufacturers. And rare earth oxyfluoride is one of the main raw materials for mixed blending type polishing powder. Before mixed blending, it is necessary to first use a screening machine to screen the rare earth oxyfluoride. The specific method is that the electric hoist transports the materials to the unpacking machine, and the lower opening of the ton bag falls into the screening machine for screening. The screened materials are transported to the storage bin of the continuous vacuum feeding machine through the vacuum conveying system.
[0003] There will be some agglomerated materials in the rare earth oxyfluoride raw materials. These agglomerated materials often cannot directly pass through the sieve holes. After stopping the machine, it is necessary to manually crush the agglomerated rare earth oxyfluoride with hands and then screen it again. This method of dealing with agglomerated materials is rather cumbersome and will reduce the working efficiency of raw material screening. Therefore, an efficient fine grinding and screening machine dedicated to the production of polishing powder is proposed. Content of the Utility Model:
[0004] The purpose of the utility model is to provide an efficient fine grinding and screening machine dedicated to the production of polishing powder to solve one of the problems raised in the above background art.

The screening assembly includes a screening box, a crushing rod, a sieve plate, a driving motor, a rotating shaft, a first limiting sleeve, a second limiting sleeve, a return spring, an annular groove, a driving motor, and a cross driving shaft;
[0006] The sieve plate is fixedly connected to the inner side wall of the screening box. The crushing rods are equidistantly and fixedly connected to the outer side wall of the rotating shaft. Both ends of the rotating shaft are respectively located inside the first limiting sleeve and the second limiting sleeve. One end of the rotating shaft is fixedly connected with a positioning wheel.

The end of the rotating shaft away from the positioning wheel is slidably connected to the outer side wall of the cross driving shaft. The return spring is sleeved outside the cross driving shaft.
[0007] As a further preference of this technical solution: The outer side wall of the positioning wheel is attached to the inner side wall of the annular groove. The driving disk is rotatably connected to the inner side wall of the second limiting sleeve.
[0008] As a further preference of this technical solution: The rotating shaft is slidably and rotatably connected to the first limiting sleeve and the second limiting sleeve, and the driving motor is installed on one side of the second limiting sleeve.

[0015] Advantages of the present utility model:
[0016] 1.

Thus, the agglomerated rare earth oxyfluoride can be broken by the crushing rod, replacing the traditional manual rubbing step, facilitating the operation, and improving the screening efficiency of rare earth oxyfluoride.
[0017] 2. In the present utility model, the driving motor drives the driving disk to rotate.

[0028] Embodiment
[0029] Please refer to Figure 1-7, the present utility model provides a technical solution: a special high-efficiency fine grinding and screening machine for producing polishing powder, including a screening assembly 101. The screening assembly 101 includes a screening box 11, a crushing rod 12, a sieve plate 13, a driving motor 14, a rotating shaft 15, a first limiting sleeve 16, a second limiting sleeve 17, a return spring 20, an annular groove 22, a driving motor 23, and a cross driving shaft 24;
[0030] The sieve plate 13 is fixedly connected to the inner side wall of the screening box 11. The crushing rods 12 are equidistantly and fixedly connected to the outer side wall of the rotating shaft 15. Both ends of the rotating shaft 15 are respectively located inside the first limiting sleeve 16 and the second limiting sleeve 17. One end of the rotating shaft 15 is fixedly connected with a positioning wheel 21. The output shaft of the driving motor 14 is fixedly connected with a driving disc 18. The annular groove 22 is opened on the side of the driving disc 18 away from the driving motor 14. One end of the cross driving shaft 24 is fixedly connected to the output shaft of the driving motor 23. The end of the rotating shaft 15 away from the positioning wheel 21 is slidably connected to the outer side wall of the cross driving shaft 24. The return spring 20 is sleeved outside the cross driving shaft 24.
[0031] In this embodiment, specifically: the outer side wall of the positioning wheel 21 fits against the inner side wall of the annular groove 22. The driving disc 18 is rotatably connected to the inner side wall of the second limiting sleeve 17. The rotating shaft 15 is slidably and rotatably connected to the first limiting sleeve 16 and the second limiting sleeve 17. The driving motor 14 is installed on one side of the second limiting sleeve 17. One side of the driving disc 18 is a slope. Therefore, when the driving motor 14 drives the driving disc 18 to rotate, the driving disc 18 pushes the rotating shaft 15 to slide in the first limiting sleeve 16 and the second limiting sleeve 17 through the positioning wheel 21.
[0032] In this embodiment, specifically: the driving motor 23 is installed on one side of the first limiting sleeve 16. Both ends of the return spring 20 respectively abut against the rotating shaft 15 and the first limiting sleeve 16 and are rotatably connected to the rotating shaft 15 and the first limiting sleeve 16 through bearings. The first limiting sleeve 16 and the second limiting sleeve 17 are symmetrically and fixedly connected to the inside of the screening box 11. The rotating shaft 15 is located above the sieve plate 13. By driving the cross driving shaft 24 through the driving motor 23, the cross driving shaft 24 drives the rotating shaft 15, and the rotating shaft 15 drives the crushing rods 12 to rotate. Thus, the agglomerated rare earth oxyfluoride can be broken by the crushing rods 12.
[0033] In this embodiment, specifically: the lower surface of the screening box 11 is provided with a support assembly 301. The support assembly 301 includes four support frames 31 and a base 35;
[0034] Four support frames 31 are symmetrically and fixedly connected to the lower surface of the screening box 11. The bottom of the support frame 31 is slidably connected to the inside of the base 35. An exciter 34 is installed on the lower surface of the screening box 11. A limiting rod 33 is slidably connected to the inside of the support frame 31. Two support springs 32 are symmetrically sleeved on the outer side wall of the limiting rod 33. The limiting rod 33 is fixedly connected to the inside of the base 35. The two ends of the support spring 32 respectively abut against the support frame 31 and the base 35. When the exciter 34 works, it drives the screening box 11. The screening box 11 reciprocates on the base 35 through the support frame 31. The screening box 11 drives the sieve plate 13, and thus the screening action of rare earth oxyfluoride can be realized.
[0035] In this embodiment, specifically: An impurity discharge hopper 36 and a raw material discharge hopper 37 are installed on the front surface of the screening box 11. The qualified rare earth oxyfluoride after screening is discharged through the raw material discharge hopper 37, while the filtered impurities are discharged through the impurity discharge hopper 36.
[0036] In this embodiment, specifically: A control switch is installed on the upper surface of the base 35. The electrical output end of the control switch is electrically connected to the electrical input ends of the drive motor 14, the transmission motor 23, and the exciter 34 through wires respectively. The electrical input end of the control switch is connected to an external power supply to supply power to the drive motor 14, the transmission motor 23, and the exciter 34.
[0037] During the working principle or structural principle, when in use, rare earth oxyfluoride is put into the screening box 11. The exciter 34 is controlled to work. The exciter 34 drives the screening box 11. The screening box 11 reciprocates on the base 35 through the support frame 31. The screening box 11 drives the sieve plate 13, and thus the screening of rare earth oxyfluoride can be realized through the sieve plate 13. The qualified rare earth oxyfluoride raw materials pass through the sieve holes, while the impurities and agglomerated rare earth oxyfluoride remain on the sieve plate 13. As the screening box 11 swings, the agglomerated rare earth oxyfluoride moves towards the direction close to the impurity discharge hopper 36 and contacts the crushing rod 12. The cross drive shaft 24 is driven by the transmission motor 23. The cross drive shaft 24 drives the rotating shaft 15. The rotating shaft 15 drives the crushing rod 12 to rotate at a high speed, and thus the agglomerated rare earth oxyfluoride can be broken by the crushing rod 12. The drive disk 18 is driven to rotate by the drive motor 14. Under the push of the return spring 20, the positioning wheel 21 remains in contact with the annular groove 22. Since one side of the drive disk 18 is a slope, the drive disk 18 pushes the positioning wheel 21. The positioning wheel 21 pushes the rotating shaft 15 to slide in the first limiting sleeve 16 and the second limiting sleeve 17. Under the push of the return spring 20, the rotating shaft 15 generates a reciprocating displacement in the left and right directions, and thus the crushing rod 12 can crush the agglomerated rare earth oxyfluoride reciprocally, avoiding small pieces of rare earth oxyfluoride from passing through the gaps of the crushing rod 12 and improving the crushing effect on the agglomerated rare earth oxyfluoride.
[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
