The center of the No. 4 bevel gear 21 is fixedly connected to the same No. 1 rod 7, and the other No. 1 rod 7 is fixedly sleeved with the same No. 4 bevel gear 21, and the No. 4 bevel gear 21 is meshed with the same No. 3 bevel gear 11. The centers of the two No. 3 bevel gears 11 are fixedly connected to the rotating shaft 12, and the two rotating shafts 12 are fixedly sleeved with cams 13. The two sliding grooves 15 are fixedly installed with protrusions 16, and the two protrusions 16 are slidably connected with the collecting box 17 together. An entrance and exit are opened on the side wall of the vibration box 1, and a door panel 18 is hingedly connected in the entrance and exit. A latch 20 is fixedly installed on the side wall of the vibration box 1, and a jack block matching the latch 20 is installed on the side wall of the door panel 18.

[0026] The toner is added into the vibration box 1 through the feed hopper 2, and the toner falls onto the No. 1 metal filter plate 4 in the vibration box 1, and then the No. 1 servo motor 5 is started, and the output end of the No. 1 servo motor 5 drives the No. 1 rod 7 to rotate in the transmission chamber 6, and the No. 1 rod 7 rotates to drive the No. 1 bevel gear 8 to rotate, and the No. 1 bevel gear 8 rotates to drive the No. 2 bevel gear 9 to rotate, and the No. 2 bevel gear 9 rotates to drive the No. 4 bevel gear 21 to mesh and rotate, so that the two No. 1 rods 7 rotate in the transmission chamber 6 at the same time, and the two No. 1 rods 7 rotate and cause the other No. 1 bevel gear 8 to rotate, so that the two No. 3 bevel gears 11 The two third bevel gears 11 rotate to drive the two rotating shafts 12 and make the two cams 13 rotate on the side wall of the vibration box 1. Since the long ends of the two cams 13 are facing each other, when the two cams 13 rotate, the long ends of the two cams 13 hit the lower end surface of the first metal filter plate 4 in turn, so that the toner on the first metal filter plate 4 falls to the second metal filter plate 14 under the vibration when the first metal filter plate 4 is hit, and the toner particles larger than the aperture of the first metal filter plate 4 will be retained on the metal filter plate 4, and when the toner particles smaller than the aperture of the first metal filter plate 4 When the toner falls onto the No. 2 metal filter plate 14, the No. 2 servo motor is started, and the No. 2 servo motor drives the No. 1 rod 7, the No. 2 rod 10, the No. 3 bevel gear 11, and the No. 4 bevel gear 21 in another transmission chamber 6 to rotate, so that the two cams 13 under the No. 2 metal filter plate 14 rotate and hit the lower end surface of the No. 2 metal filter plate 14 in turn, so that the toner smaller than the aperture of the No. 2 metal filter plate 14 falls into the collection box 17. At this time, the No. 1 metal filter plate 4 and the No. 2 metal filter plate 14 complete the graded filtration of the particles in the toner, and the cam 13 hits the No. 1 metal filter plate 14. The hitting of the mesh plate 4 and the lower end of the second metal filter plate 14 can make the larger toner particles remaining on the first metal filter plate 4 and the second metal filter plate 14 vibrate, and the toner is vibrated away from the large particles and falls off, and the filtering efficiency of the toner in the vibration box 1 is better. The filtered toner is in the collection box 17. The staff first separates the latch 20 from the socket block, and then draws the collection box 17 out of the vibration box 1 along the side wall of the sliding groove 15 and the protrusion 16. At this time, the collection of the filtered toner is completed, which is convenient for the staff to collect the filtered toner, saving time and effort;

[0027] Among them, one end of the two No. 1 rods 7 away from the No. 1 servo motor 5 and the No. 2 servo motor is rotatably connected to the inner wall of the transmission cavity 6.

[0028] By making one end of the two No. 1 rods 7 away from the No. 1 servo motor 5 and the No. 2 servo motor rotatably connected to the inner wall of the transmission chamber 6, the two No. 1 rods 7 can rotate in the transmission chamber 6;

[0029] The end of the second rod 10 which is away from the first bevel gear 8 is rotatably connected to the inner wall of the transmission chamber 6 .

[0030] By making the end of the second rod 10 away from the first bevel gear 8 rotatably connected to the inner wall of the transmission chamber 6, the second rod 10 can rotate in the transmission chamber 6;

[0031] Among them, the long ends of the two opposite cams 13 are back to back in the vibration box 1 in a static state and remain parallel to the No. 1 metal filter plate 4 and the No. 2 metal filter plate 14. The mesh aperture of the No. 1 metal filter plate 4 is larger than the mesh aperture of the No. 2 metal filter plate 14.

[0032] By making the long ends of the two opposite cams 13 face each other in the vibration box 1 in a static state and keep them parallel to the No. 1 metal filter plate 4 and the No. 2 metal filter plate 14, the parallelism can ensure that the staff will not collide with the two cams 13 when taking out the No. 1 metal filter plate 4 and the No. 2 metal filter plate 14, so that the staff can take and collect the No. 1 metal filter plate 4 and the No. 2 metal filter plate 14. At the same time, the mesh plate aperture of the No. 1 metal filter plate 4 is larger than the mesh plate aperture of the No. 2 metal filter plate 14, so that the toner can be filtered by the No. 1 metal filter plate 4 first, and then fall onto the No. 2 metal filter plate 14 to be filtered;

[0033] A handle 19 is fixedly mounted on the door panel 18 , and an anti-slip sleeve is fixedly mounted on the handle 19 .

[0034] By providing the door panel 18 and the handle 19, when the staff needs to maintain or replace the No. 1 metal filter plate 4, the No. 2 metal filter plate 14, and the collection box 17, they only need to use the handle 19 to open the door panel 18 to complete the maintenance and replacement of the components in the vibration box 1, which saves time and effort;

[0035] A draw-out slot is provided on the side wall of the collecting box 17 .

[0036] By providing the draw-out slot, the staff can draw the collection box 17 out of the vibration box 1 by hand through the draw-out slot.

[0037] The working principle of the utility model is as follows: first, toner is added into the vibration box 1 through the feed hopper 2, and the toner falls onto the No. 1 metal filter plate 4 in the vibration box 1, and then the No. 1 servo motor 5 is started, and the output end of the No. 1 servo motor 5 drives the No. 1 rod 7 to rotate in the transmission chamber 6, and the No. 1 rod 7 rotates to drive the No. 1 bevel gear 8 to rotate, and the No. 1 bevel gear 8 rotates to drive the No. 2 bevel gear 9 to rotate, and the No. 2 bevel gear 9 rotates to drive the No. 4 bevel gear 21 to mesh and rotate, so that the two No. 1 rods 7 rotate in the transmission chamber 6 at the same time. The two No. 1 rods 7 rotate and make the other No. 1 bevel gear 8 rotate, so that the two No. 3 bevel gears 11 mesh and rotate. The two No. 3 bevel gears 11 rotate to drive the two rotating shafts 12 and make the two cams 13 rotate on the side wall of the vibration box 1. Since the long ends of the two cams 13 face each other, when the two cams 13 rotate, the long ends of the two cams 13 hit the lower end surface of the No. 1 metal filter plate 4 in turn, so that the toner on the No. 1 metal filter plate 4 vibrates when the No. 1 metal filter plate 4 is hit. The toner particles with a larger aperture than the first metal filter plate 4 will be retained on the metal filter plate 4. When the toner particles with a smaller aperture than the first metal filter plate 4 fall onto the second metal filter plate 14, the second servo motor is started, and the second servo motor drives the first rod 7, the second rod 10, the third bevel gear 11, and the fourth bevel gear 21 in another transmission chamber 6 to rotate, so that the two cams 13 under the second metal filter plate 14 rotate and rotate the second metal filter plate 14 in turn. The lower end surface is struck to make the toner smaller than the aperture of the second metal filter plate 14 fall into the collection box 17. At this time, the first metal filter plate 4 and the second metal filter plate 14 complete the graded filtration of the particles in the toner. The cam 13 strikes the lower ends of the first metal filter plate 4 and the second metal filter plate 14 to vibrate the larger toner particles remaining on the first metal filter plate 4 and the second metal filter plate 14. At this time, the toner is vibrated away from the large particles and falls, and the toner filtering efficiency in the vibration box 1 is better.

[0038] The filtered toner is in the collection box 17. The staff first separates the latch 20 from the socket block, then uses the handle 19 to open the door panel 18, and then puts his hand into the draw-out groove on the side wall of the collection box 17 to draw the collection box 17 out of the vibration box 1 along the sliding groove 15 and the side wall of the protrusion 16. At this time, the collection of the filtered toner is completed, which is convenient for the staff to collect the filtered toner, saving time and effort.

[0039] When it is necessary to collect toner particles whose apertures are larger than the first metal filter plate 4 and the second metal filter plate 14, it is only necessary to pull the first metal filter plate 4 and the second metal filter plate 14 out of the plate slot 3 in the vibration box 1 into the vibration box 1 to complete the collection and processing of the toner particles on the first metal filter plate 4 and the second metal filter plate 14.

[0040] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and utility model concept of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
