[0050] Example 2

[0051] See also Figure 8-Figure 10 As shown, a plurality of support frames 401 are fixedly connected to the top of the inner wall of the aggregation funnel 4, and the grinding disc 12 is fixedly installed on the top of the plurality of support frames 401. A gap is left between the grinding disc 12 and the top inner wall of the aggregation funnel 4. A plurality of grooves 41 are provided on the inclined inner wall of the aggregation funnel 4, and a collection trough 42 is provided at the bottom of the aggregation funnel 4. A discharge pipe 43 is fixedly connected to the bottom of the collection trough 42, and a cylindrical groove 44 is provided on the top of the inner wall of the discharge pipe 43. The bottom of the center tube 3 is rotatably arranged inside the cylindrical groove 44.

[0052] Cleaning bristles 501 are fixedly installed on the bottom side walls of the cleaning plate 5, and several cleaning plates 5 are arranged at the bottom of a mounting seat 51. The mounting seat 51 is arranged at the bottom of the grinding disc 12, and the mounting seat 51 is fixedly installed on the side wall of the central tube 3. Several receiving grooves 511 are opened at the bottom of the mounting seat 51, and two groups of mounting bases 52 are fixedly connected to the bottom inner walls of the receiving grooves 511. Connecting plates 33 are rotatably installed on the mounting bases 52. Long grooves 54 are opened on the top side walls of the cleaning plate 5, and two connecting rods 541 are symmetrically fixedly connected to the inner walls of the long grooves 54. The ends of the connecting plates 33 away from the mounting bases 52 are rotatably installed on the corresponding connecting rods 541, and a cylindrical opening 55 is commonly opened between the bottoms of the several cleaning plates 5 and the mounting seat 51.

[0053] The limiting plate 36 is arranged inside the cylindrical opening 55. An annular cylindrical groove 551 is formed on the side wall of the limiting plate 36 and the inner wall of the cylindrical opening 55. A plurality of stoppers 361 are fixedly connected inside the annular cylindrical groove 551 on the limiting plate 36. The stoppers 361 are arranged inside the annular cylindrical groove 551. An arc-shaped limiting rod 56 is arranged between every two stoppers 361. The arc-shaped limiting rod 56 is slidably arranged inside the annular cylindrical groove 551.

[0054] By utilizing the limiting effect of the arc-shaped limiting rod 56 on the cleaning plate 5, the motor 132 is started to reverse, and the spiral blade 372 is also reversed. There will be no effect of lifting the material, and due to the inertia, the cleaning plate 5 will open, and the mounting seat 51 will fit with the inner wall of the collecting funnel 4, so that the ground material inside the collecting funnel 4 is cleaned and finally falls through the discharge pipe 43 for extraction and collection.

[0055] When in use, the motor 132 is started, and the grinding block 2, the central cylinder 3, and the cleaning plate 5 start to rotate at the same time through the transmission of the pinion 131, the driving gear 133 and the internal gear 134, and the driving gear 133 and the internal gear 134 rotate in opposite directions. When the central cylinder 3 rotates, the receiving plate 34 and the grinding block 2 rotate synchronously;

[0056] Afterwards, the raw material is injected into the device through the feed port 111 and falls on the receiving plate 34. The receiving plate 34 rotates due to the setting of the bristles 115, and relative motion occurs between the receiving plate 34 and the bristles 115. The bristles 115 sweep the raw material and drop it on the grinding plate 12. Afterwards, the grinding block 2 can grind the raw material.

[0057] At the beginning of grinding, there are many large-volume materials, and the control motor 132 rotates at a high speed, and the central cylinder 3 rotates faster. Due to the effect of centrifugal force, several grinding blocks 2 slide along the insertion rod 311, the connecting plate 33 rotates, the ring 31 moves up, and the distance between the grinding disc 12 and the grinding block 2 increases, so that large-particle materials are ground first;

[0058] Thus, by reducing the rotation speed of the motor 132, the material can be fully ground;

[0059] During the grinding process, insufficiently ground materials may fall through the gap between the grinding disc 12 and the aggregate hopper 4. Since the insufficiently ground materials are relatively large in size, they will roll along the inner wall of the aggregate hopper 4 to the inside of the central tube 3, and then be transported by the spiral blades 372, and fall back onto the grinding disc 12 through the return channel 331, the chuck 341 and the drop channel 351 for re-grinding, thereby avoiding the situation where the materials cannot be fully ground due to the existence of grinding gaps between the grinding structures and the different sizes of the raw materials themselves.

[0060] During this process, fully ground powdered materials may fall down. Since the powdered materials are easy to stick to the wall, they will be adsorbed and stay on the inner wall of the groove 41 and the collecting funnel 4 until the grinding process is completed.

[0061] Among them, through the setting of the cleaning component, the motor 132 rotates forward, and during grinding, the arc-shaped limit rod 56 will slide to the inside of the annular cylindrical groove 551 between the limit plate 36 and the cleaning plate 5 due to inertia, and limit the cleaning plate 5. When the grinding is completed, the motor 132 will reverse, and the arc-shaped limit rod 56 will move out of the annular cylindrical groove 551 on the cleaning plate 5, and the cleaning plate 5 will lose the limit. Due to the action of centrifugal force, the connecting plate 33 will rotate, and the cleaning hair 501 will fit with the inner wall of the aggregation funnel 4, sweeping the material on the aggregation funnel 4, and cleaning the ground material inside the aggregation funnel 4. Since the motor 132 is reversed, the spiral blade 372 is also reversed, and there will be no effect of lifting the material. Finally, the ground material will fall through the discharge pipe 43, which is convenient for extraction and collection.

[0062] Example 3

[0063] See also Fig.11 As shown, a method for grinding and extracting for toothpaste production comprises the following steps:

[0064] Step 1, start the motor 132, through the transmission of the pinion 131, the driving gear 133 and the internal gear 134, the grinding block 2, the center cylinder 3, and the cleaning plate 5 start to rotate at the same time;

[0065] Step 2: Inject the raw material into the device through the feed port 111, and then it will fall on the grinding disc 12, and the grinding block 2 will grind the raw material;

[0066] Step 3: The ground raw materials will fall into the collecting hopper 4. The powdered raw materials are easy to hang on the wall and will be adsorbed on the groove 41 and the inner wall of the collecting hopper 4. The materials with larger particles will roll into the center tube 3, be transported by the spiral blades 372, and return to the grinding disc 12 for re-grinding.

[0067] Step 4, after grinding is completed, start the motor 132 to reverse, and the spiral blade 372 also reverses, which will not have the effect of lifting the material, and due to the inertia cleaning plate 5 will open, the mounting seat 51 will fit with the inner wall of the aggregate hopper 4, and the ground material inside the aggregate hopper 4 will be cleaned, and finally fall through the discharge pipe 43 for extraction and collection.
