Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a zirconia powder screening machine, including a bottom plate 1, a bracket 2, a motor 3, a transmission mechanism 4, a transmission rod 401, a cam 402, a base 5, a square rod 6, a wheel set 7, a spring 8, a rod sleeve 9, a knob 10, a collection box 11, a roller 12, a positioning arm 13, a rotating sleeve 14, a lower sieve frame 15, a middle sieve frame 16, an upper sieve frame 17 and a clamping arm 18. The end of the upper surface of the bottom plate 1 is fixedly connected with a bracket 2, and the upper end surface of the bracket 2 is fixedly provided with a motor 3. The lower end of the output shaft of the motor 3 is provided with a transmission mechanism 4. The upper surface of the bottom plate 1 on the side of the transmission mechanism 4 is fixedly connected with a base 5. The inner wall of the base 5 is movably connected with a square rod 6. One end of the outer wall of the square rod 6 is fixedly connected with a wheel set 7, and the other end of the outer wall of the square rod 6 is sleeved with a rod sleeve 9. The end of the rod sleeve 9 is fixedly connected with a collection box 11. The outer walls on both sides of the collection box 11 are respectively fixed with a positioning arm 13. The upper end of the outer wall of the positioning arm 13 is sleeved with a rotating sleeve 14. The lower sieve frame 15 is slidably installed on the upper inner wall of the collection box 11. The upper inner wall of the lower sieve frame 15 is slidably connected with a middle sieve frame 16. The upper inner wall of the middle sieve frame 16 is slidably provided with an upper sieve frame 17. The outer walls on both sides of the upper sieve frame 17 are respectively fixed with a clamping arm 18.

[0022] The transmission mechanism 4 includes a transmission rod 401 and a cam 402. The transmission rod 401 is fixedly installed at the lower end of the output shaft of the motor 3, and the outer wall of the transmission rod 401 is fixedly connected with a cam 402, which is convenient to drive the transmission mechanism 4 by the motor 3, so that the collection box 11, the lower sieve frame 15, the middle sieve frame 16 and the upper sieve frame 17 move back and forth at the same time for material screening.

[0023] The transmission rod 401 and the bottom plate 1 form a rotating structure, and the cam 402 and the wheel set 7 are in contact with each other, which is convenient for the transmission rod 401 to rotate relative to the bottom plate 1, so that the cam 402 rotates back and forth to press the wheel set 7.

[0024] The base 5 and the square rod 6 are slidably connected, and the outer wall of the side of the upper end of the base 5 is connected to the outer wall of the wheel set 7 through a spring 8, which is convenient for elastically supporting the wheel set 7 through the spring 8. When the cam 402 rotates, the wheel set 7 drives the square rod 6 to slide back and forth relative to the base 5.

[0025] The upper inner wall of the end of the rod sleeve 9 is provided with a knob 10, and the knob 10 is threadedly connected to the rod sleeve 9 and the square rod 6 respectively, and the rod sleeve 9 and the square rod 6 form a sliding structure, which is convenient for the user to rotate the knob 10 so that the knob 10 disengages from the rod sleeve 9 and the square rod 6, thereby facilitating the user to disassemble and assemble the collection box 11. And as the collection box 11 moves, the collection box 11 drives the rod sleeve 9 to slide relative to the square rod 6.

[0026] The lower surface of the collection box 11 is provided with rollers 12, and the rollers 12 are in contact with the bottom plate 1. The rotary sleeve 14 is threadedly arranged with the positioning arm 13 and the clamping arm 18 respectively. The mesh number of the lower sieve frame 15 is larger than that of the middle sieve frame 16, and the mesh number of the middle sieve frame 16 is larger than that of the upper sieve frame 17. When the collection box 11 moves back and forth, it is convenient for the rollers 12 to roll on the bottom plate 1, so that the collection box 11 moves back and forth stably. And it is convenient for the user to rotate the rotary sleeve 14 so that the rotary sleeve 14 moves relative to the clamping arm 18 and disengages from the positioning arm 13, thereby facilitating the user to disassemble the sieve frame, and facilitating the sieve frames with different mesh numbers to move back and forth, so that zirconia powder with different sizes accumulates in the collection box 11, the lower sieve frame 15, the middle sieve frame 16 and the upper sieve frame 17.

[0027] Working principle: When using this zirconia powder screening machine, first, as Figures 1-4As shown, the user moves the collection box 11 so that the collection box 11 drives the rod sleeve 9 to be sleeved on the square rod 6. Then the user inserts the knob 10 into the rod sleeve 9 and tightens the knob 10. At this time, the knob 10 is inserted into the rod sleeve 9 and the square rod 6, and at the same time the roller 12 is in contact with the bottom plate 1. Next, the user inserts the lower sieve frame 15 into the collection box 11. Subsequently, the user inserts the middle sieve frame 16 into the lower sieve frame 15. Then the user inserts the upper sieve frame 17 into the middle sieve frame 16. Next, the user rotates the rotating sleeve 14. At this time, the rotating sleeve 14 moves downward relative to the clamping arm 18. And as the user continuously rotates the rotating sleeve 14, finally the rotating sleeve 14 is sleeved on the positioning arm 13. Similarly, the remaining rotating sleeves 14 are operated to complete the assembly of the device. Then the user pours the zirconia powder to be processed into the upper sieve frame 17. Next, the user starts the motor 3. Then the motor 3 drives the transmission rod 401 to rotate relative to the bottom plate 1. Subsequently, the transmission rod 401 drives the cam 402 to rotate. At this time, the cam 402 presses the wheel set 7 supported by the spring 8 back and forth. Then the wheel set 7 drives the square rod 6 to slide back and forth relative to the base 5. Next, the square rod 6 drives the rod sleeve 9 to make the collection box 11 move back and forth. At the same time, the collection box 11 drives the roller 12 to roll in contact with the bottom plate 1, so that the collection box 11, the lower sieve frame 15, the middle sieve frame 16 and the upper sieve frame 17 move back and forth at the same time to screen the zirconia powder. At this time, zirconia powders of different sizes are accumulated in the collection box 11, the lower sieve frame 15, the middle sieve frame 16 and the upper sieve frame 17. Therefore, the device is convenient for screening the zirconia powder in detail, making the zirconia powder divided into different sizes, so as to facilitate the subsequent treatment of the zirconia powder and improve the practicability of the device.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
