[0036] Embodiment 1

[0037] An oscillating sieving device for lime powder packaging includes a base 1, an outer shell 2, a sieve mesh 22, a guide rod 23, a first spring 24, a discharge hopper 3, a feed hopper 31, a material receiving frame 32, a drive mechanism 4 and a cleaning mechanism 5. Please refer to Figures 1-8 As shown, the outer shell 2 is installed at the rear side of the top of the base 1 by welding connection. The middle part of the left side of the outer shell 2 communicates with the discharge hopper 3. The middle of the top of the outer shell 2 communicates with the feed hopper 31. Guide rods 23 are symmetrically fixed on the left and right sides of the inner top and inner bottom of the outer shell 2 in the front and rear directions. A sieve mesh 22 is slidably sleeved between the four guide rods 23. When the lime powder falls onto the sieve mesh 22, the sieve mesh 22 can oscillate and screen the lime powder. The sieve mesh 22 is inclined. Four first springs 24 are connected between the bottom of the sieve mesh 22 and the inner bottom of the outer shell 2. The four first springs 24 are respectively sleeved on the four guide rods 23. A material receiving frame 32 is slidably inserted through the lower part of the front side of the outer shell 2. The material receiving frame 32 is used to collect the qualified lime powder. A drive mechanism 4 is arranged on the right side of the outer shell 2. When the drive mechanism 4 operates, the drive mechanism 4 can drive the sieve mesh 22 to move up and down. A cleaning mechanism 5 is arranged on the outer shell 2. When the cleaning mechanism 5 operates, the cleaning mechanism 5 can remove the lime powder stuck on the sieve mesh 22.

[0038] It also includes a perspective plate 21. Please refer to Figure 1 and Figure 2As shown, a perspective plate 21 is fixedly penetrated and connected to the upper left side of the outer shell 2.

[0039] The driving mechanism 4 includes a mounting frame 41, a stepping motor 42, and a cam 43. Please refer to Figure 1 , Figure 2 and Figure 5 As shown, the mounting frame 41 is installed on the lower part of the right outer side of the outer shell 2 by welding. The stepping motor 42 is fixedly connected to the mounting frame 41. The output shaft of the stepping motor 42 rotatably penetrates the right side of the outer shell 2. The end of the output shaft of the stepping motor 42 is fixedly connected with the cam 43. The cam 43 is located below the screen 22. When the cam 43 rotates and contacts the screen 22, the cam 43 can drive the screen 22 to move.

[0040] The cleaning mechanism 5 includes a cleaning roller 51, rollers 52, sliding blocks 53, guide rods 54, and second springs 55. Please refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, the guide rods 54 are fixedly connected to the middle parts of the front and rear inner sides of the outer shell 2. The sliding blocks 53 are slidably sleeved on the front and rear guide rods 54. The second springs 55 are connected between the left side surfaces of the front and rear sliding blocks 53 and the inner side of the outer shell 2. The second springs 55 are sleeved on the guide rods 54. The cleaning roller 51 is fixedly connected between the inner side surfaces of the front and rear sliding blocks 53. When the cleaning roller 51 moves to the left, the cleaning roller 51 can remove the lime powder stuck on the screen 22. The rollers 52 are symmetrically and fixedly sleeved on the front and rear sides of the cleaning roller 51. The front and rear rollers 52 are in contact with the top of the screen 22.

[0041] First, place the collection container under the discharge hopper 3, and then start the drive mechanism 4. When the drive mechanism 4 operates, it drives the screen 22 to move upward. The first spring 24 is stretched. As the screen 22 moves upward, it drives the cleaning mechanism 5 to move leftward. As the drive mechanism 4 continues to operate and reset, the drive mechanism 4 disengages from the screen 22. Due to the action of the first spring 24, the screen 22 moves downward to reset. At the same time, the cleaning mechanism 5 also moves rightward to reset. Repeating this way, the screen 22 can continuously move up and down, and the cleaning mechanism 5 can continuously move left and right. At this time, lime powder can be poured into the feed hopper 31. The lime powder in the feed hopper 31 falls into the housing 2. The lime powder in the housing 2 contacts the screen 22. The screen 22 moves up and down to oscillate and screen the lime powder. The qualified lime powder is screened into the receiving frame 32, while the lumpy lime powder remains on the screen 22. When the screen 22 moves upward, it also drives the lumpy lime powder to move upward. When the cleaning mechanism 5 moves leftward, it pushes the lumpy lime powder into the discharge hopper 3. The lumpy lime powder in the discharge hopper 3 falls into the collection container. In this way, after a long time of screening, the holes on the screen 22 will not be blocked by the lumpy lime powder, which affects subsequent screening. At the same time, when screening the lime powder, people can view the screening situation of the lime powder in the housing 2 through the transparent plate 21. When all the lime powder has been screened, turn off the drive mechanism 4. The drive mechanism 4 stops operating, the screen 22 stops moving up and down, and the cleaning mechanism 5 also stops moving left and right. Then, pull the receiving frame 32 forward to outside the housing 2 and make the receiving frame 32 disengage from the base 1. Then pour the appropriate lime powder in the receiving frame 32 for packaging, and pick up the collection container to screen the lumpy lime powder again. After all the appropriate lime powder has been poured out, place the receiving frame 32 back on the base 1 and push the receiving frame 32 backward to reset.

[0042] After the collection container is placed properly, start the stepper motor 42 to drive the cam 43 to rotate forward. When the cam 43 rotates forward and contacts the screen 22, the cam 43 drives the screen 22 to move upward. As the screen 22 moves upward, it drives the cleaning mechanism 5 to move leftward. As the cam 43 continues to rotate forward, the cam 43 disengages from the screen 22. Due to the action of the first spring 24, the screen 22 moves downward to reset, and the cleaning mechanism 5 also moves rightward to reset. Then, lime powder can be poured into the housing 2 through the feed hopper 31. The screen 22 moves up and down to screen the lime powder, and the cleaning mechanism 5 removes the lumpy lime powder from the screen 22. When all the lime powder has been screened, turn off the stepper motor 42. The stepper motor 42 stops driving the cam 43 to rotate, and the screen 22 stops moving up and down.

[0043] When the stepping motor 42 starts to rotate forward, the cam 43 rotates forward to drive the screen 22 to move upward. Since the screen 22 is inclined, the upward movement of the screen 22 drives the front and rear rollers 52 to move leftward. The leftward movement of the front and rear rollers 52 drives the cleaning roller 51 to move leftward. The leftward movement of the cleaning roller 51 drives the front and rear sliding blocks 53 to move leftward, and the second spring 55 is compressed. When the cam 43 continues to rotate forward and disengages from the screen 22, the screen 22 moves downward to reset and disengages from the front and rear rollers 52. Due to the action of the second spring 55, the front and rear sliding blocks 53 move rightward to reset and drive the cleaning roller 51 to move rightward to reset. The rightward movement of the cleaning roller 51 to reset drives the front and rear rollers 52 to move rightward to reset. Furthermore, when the lumpy lime powder is screened out on the screen 22, the screen 22 drives the lumpy lime powder to move upward, and the leftward movement of the cleaning roller 51 pushes the lumpy lime powder into the discharge hopper 3, and the lumpy lime powder then falls into the collection container. In this way, it can be avoided that the lumpy lime powder accumulates and blocks the holes of the screen 22, affecting subsequent screening. After all the lime powder is screened, the stepping motor 42 is turned off, the screen 22 stops moving up and down, and the screen 22 also stops driving the front and rear rollers 52 to move leftward, and the cleaning roller 51 also stops moving left and right.

[0044] Embodiment 2

[0045] On the basis of Embodiment 1, there is also a blowing mechanism 6. The blowing mechanism 6 includes a mounting frame 61, a heating pipe 62, a synchronous belt 63, a rotating shaft 64 and a fan 65. Please refer to Figure 2 、 Figure 9 and Figure 10 As shown, the mounting frame 61 is fixedly penetrated through the upper right part of the outer shell 2. The left side surface of the mounting frame 61 is fixedly connected with the heating pipe 62. The rotating shaft 64 is rotatably penetrated through the middle of the mounting frame 61. The fan 65 is fixedly sleeved on the left side of the rotating shaft 64. When the fan 65 rotates, the fan 65 can blow out the wind. The output shaft of the stepping motor 42 is provided with the synchronous belt 63, and the synchronous belt 63 is connected to the right side of the rotating shaft 64 through a one-way clutch.

[0046] There is also a separating mechanism 7. The separating mechanism 7 includes a lead screw 71, a sliding frame 72, a magnetic attraction block 73, a guide post 74, a third spring 75, a separating plate 76, a thin rod 77 and a fifth spring 78. Please refer to Figure 1 、 Figure 2 、 Figure 11 and Figure 12As shown, a partition plate 76 is slidably inserted into the upper right part of the outer shell 2. When the partition plate 76 moves leftward and contacts the bottom of the feed hopper 31, the partition plate 76 can enclose the inside of the feed hopper 31. Thin rods 77 are slidably inserted into the upper right part of the outer shell 2 symmetrically in the front and back. The left ends of the thin rods 77 on both the front and back sides are fixedly connected to the left part of the partition plate 76. Fifth springs 78 are symmetrically connected between the left part of the partition plate 76 and the upper part of the right inner side surface of the outer shell 2. The fifth springs 78 are sleeved on the thin rods 77. A guide post 74 is fixedly connected to the middle of the upper right outer side surface of the outer shell 2. The guide post 74 is located above the mounting frame 61. A sliding frame 72 is slidably sleeved on the guide post 74. When the sliding frame 72 moves leftward and contacts the partition plate 76, the sliding frame 72 can drive the partition plate 76 to move. A third spring 75 is connected between the right inner side surface of the sliding frame 72 and the upper part of the right outer side surface of the outer shell 2. The right end of the rotating shaft 64 is fixedly connected to a lead screw 71. A magnetic attraction block 73 is rotationally connected to the lead screw 71 in a threaded manner. The lower part of the sliding frame 72 is sleeved on the magnetic attraction block 73. The sliding frame 72 is in magnetic contact with the magnetic attraction block 73. When the magnetic attraction block 73 moves, the magnetic attraction block 73 can drive the sliding frame 72 to move.

[0047] When the stepping motor 42 starts to rotate forward, the stepping motor 42 also drives the synchronous belt 63 to rotate forward. Due to the effect of the one-way clutch, the forward rotation of the synchronous belt 63 will not drive the rotating shaft 64 to rotate forward. When all the lime powder has been screened, the stepping motor 42 is turned off, and the stepping motor 42 stops driving the synchronous belt 63 to rotate forward. At this time, the stepping motor 42 is started to rotate in reverse to drive the synchronous belt 63 to rotate in reverse. The reverse rotation of the synchronous belt 63 drives the rotating shaft 64 to rotate in reverse. The reverse rotation of the rotating shaft 64 drives the fan 65 to rotate in reverse. The reverse rotation of the fan 65 blows out the wind. The heating tube 62 is started, and the operation of the heating tube 62 makes the wind become hot air. The hot air is blown into the outer shell 2, and part of the hot air will be discharged through the feed hopper 31. The hot air blows the lime powder remaining in the outer shell 2, and the lime powder falls into the material receiving frame 32. At the same time, the hot air is also blown into the discharge hopper 3. The hot air blows out the lumpy lime powder in the discharge hopper 3 for collection. When all the lime powder remaining in the outer shell 2 and the discharge hopper 3 has been collected, the stepping motor 42 is turned off, and the stepping motor 42 stops driving the rotating shaft 64 to rotate in reverse through the transmission of the synchronous belt 63. The rotating shaft 64 stops driving the fan 65 to rotate in reverse, and then the heating tube 62 is turned off. In this way, it can be avoided that the lime powder remains and cannot be collected and processed, resulting in waste.

[0048] When the stepping motor 42 starts to reverse, the rotating shaft 64 reverses to drive the lead screw 71 to reverse. The reverse rotation of the lead screw 71 drives the magnetic attraction block 73 to move leftward. The leftward movement of the magnetic attraction block 73 drives the sliding frame 72 to move leftward, and the third spring 75 is compressed. The leftward movement of the sliding frame 72 contacts the isolation plate 76. The sliding frame 72 drives the isolation plate 76 to move leftward, and the fifth spring 78 is stretched. The leftward movement of the isolation plate 76 contacts the bottom of the feed hopper 31, and the isolation plate 76 seals the inside of the feed hopper 31. At this time, the hot air will not be blown into the feed hopper 31. As the magnetic attraction block 73 moves leftward to the maximum stroke, the magnetic attraction block 73 stops moving leftward, and the sliding frame 72 also stops driving the isolation plate 76 to move leftward. If the lead screw 71 continues to reverse, it will drive the magnetic attraction block 73 to reverse. Since the magnetic attraction block 73 and the sliding frame 72 are in magnetic contact, the reverse rotation of the magnetic attraction block 73 idles in the sliding frame 72. After the residual lime powder in the housing 2 and the discharge hopper 3 is cleared and collected, the stepping motor 42 is turned off, the rotating shaft 64 stops driving the lead screw 71 to reverse, and the lead screw 71 stops driving the magnetic attraction block 73 to reverse. Due to the action of the third spring 75, the sliding frame 72 moves rightward to reset and drives the magnetic attraction block 73 to move rightward to reset. The sliding frame 72 resets and disengages from the isolation plate 76. Due to the action of the fifth spring 78, the isolation plate 76 moves rightward to reset and disengages from the bottom of the feed hopper 31. In this way, a large amount of hot air can be prevented from being discharged through the feed hopper 31, which affects the cleaning effect of the residual lime powder in the housing 2 and the discharge hopper 3.

[0049] Embodiment 3

[0050] On the basis of Embodiment 1 and Embodiment 2, it further includes an assisting mechanism 8. The assisting mechanism 8 includes a mounting block 81 and an assisting wheel 82. Please refer to Figure 2 、 Figure 13 and Figure 14 As shown, on the front and rear sides of the outer bottom of the material receiving frame 32, mounting blocks 81 are symmetrically and fixedly connected left and right. The four mounting blocks 81 are all slidably connected to the top of the base 1, and assisting wheels 82 are rotatably connected to the bottom of the four mounting blocks 81 symmetrically in the front and rear directions.

[0051] It further includes a locking mechanism 9. The locking mechanism 9 includes a fixed block 91 and an electromagnetic block 92. Please refer to Figure 2 and Figure 15 As shown, a fixed block 91 is installed on the left side of the inner top of the housing 2 by welding connection. An electromagnetic block 92 is fixedly connected to the right side of the fixed block 91. When the isolation plate 76 moves leftward and contacts the electromagnetic block 92, the electromagnetic block 92 can suck and fix the isolation plate 76.

[0052] When the material receiving frame 32 moves, the material receiving frame 32 also drives the mounting block 81 to move. The movement of the mounting block 81 guides the material receiving frame 32. At the same time, the movement of the mounting block 81 drives the assisting wheel 82 to move, and the assisting wheel 82 guides the mounting block 81. In this way, the movement of the material receiving frame 32 can be made more stable and smooth.

[0053] When the partition plate 76 moves leftward to contact the bottom of the feed hopper 31, the partition plate 76 moves leftward to contact the electromagnet 92, starting the electromagnet 92. The electromagnet 92 is activated to attract the partition plate 76 by magnetic force. When the partition plate 76 needs to be reset, the electromagnet 92 is turned off, and the electromagnet 92 releases the partition plate 76, so that the partition plate 76 can move rightward to reset. In this way, it is possible to avoid the phenomenon that the partition plate 76 moves rightward due to external force factors, which affects the removal of the remaining lime powder.

[0054] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention all fall within the scope claimed by the present invention.
