[0082] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.
[0083] The embodiment of the present invention provides an automation system suitable for a planetary ball mill, referring to Figure 1-16 As shown, the planetary ball mill 100, a feeding structure 200, a material distribution structure 300, a capping structure 400, a rotating lifting structure 500, and a material suction structure 600 are included. The planetary ball mill 100 includes a plurality of ball mills 110, which can both rotate on their own and realize orbital revolution. The aforementioned feeding structure 200 is used to feed materials to the material distribution structure 300; the material distribution structure 300 includes an intermediate bin 310 and a material distribution bin 320, the intermediate bin 310 is connected to the feeding structure 200 to receive the feeding of the feeding structure 200, and the material distribution bin 320 is connected to the intermediate bin 310, and the powder passing through the intermediate bin 310 is diverted into the material distribution bin 320. The material distribution bin 320 can feed materials one-to-one into the ball mill 110 through the material distribution bin outlet at the bottom. The aforementioned sealing structure 400 is used to cover the ball mill 110, and revolves and rotates with the ball mill 110; the material distribution structure 300 and the sealing structure 400 are arranged on the rotating lifting structure 500, and rotate and lift under the drive of the rotating lifting structure 500; the aforementioned suction structure 600 includes a suction pipe, which is used to suck the powder ground in the ball mill 110 out of the ball mill 110.
[0084] The automation system includes a first state, a second state and a third state. When the automation system is in the first state, the material distribution structure 300 is driven by the rotating lifting structure 500 to rotate to the bottom of the feeding structure 200 and then moves upward. The intermediate bin 310 receives the feeding of the feeding structure 200. After entering the intermediate bin 310, the powder is diverted to each material distribution bin 320 in preparation for feeding the ball mill 110. When the material distribution structure 300 moves upward, the sealing structure 400 connected to the rotating lifting structure 500 also moves upward synchronously. At this time, the sealing structure 400 and the ball mill 110 are in a separated structure, and the suction pipe is inserted into the ball mill 110 to suck out the ground powder.
[0085] When the automation system is in the second state, the suction pipe sucks out all the ground powder in the ball mill 110 and removes it from the ball mill 110. At this time, the material distribution structure 300 rotates to the top of the ball mill 110, moves downward and puts the powder to be ground into the ball mill 110. At this time, the capping structure 400 moves to another place driven by the rotating lifting structure 500 to prevent the capping structure 400 from interfering with the feeding of the material distribution structure 300.
[0086] The automation system is in the third state, the cover structure 400 moves to the top of the ball mill 110 and moves downward until the cover structure 400 covers the ball mill 110 . At this time, the planetary ball mill 100 works to grind the powder in the ball mill 110 .
[0087] The automated system sequentially switches between the first state, the second state and the third state to complete a grinding of the powder.
[0088] In this application, by designing an automation system suitable for a planetary ball mill, the feeding of powders before grinding and the suction of powders after grinding can be automatically processed without manual intervention, which can effectively improve the degree of automation. At the same time, the powders are transported under closed conditions, which can effectively avoid dust.
[0089] The automated system further includes a feeding structure 700 and a drying structure 800 .
[0090] Reference Figure 2-5 The drying structure 800 includes a drying hopper 810 and a drying mechanism 820. The starting end and the end of the drying mechanism 820 are both arranged in the drying hopper 810. The powder enters the drying mechanism 820 from the starting end to be dried and is discharged to the drying hopper 810 from the end. After multiple cycles, the water content of the powder can be reduced.
[0091] Since the particle size of the powder is small, the powder will hang on the wall during transportation. Therefore, drying the powder before entering the feeding structure 200 for transportation can effectively reduce the hanging on the wall. In the present application, the water content of the powder is reduced by multiple cycles. On the one hand, the powder is dried to reduce the water content, and on the other hand, the space occupied by the drying structure 800 is reduced.
[0092] The aforementioned feeding structure 700 includes a feeding bin 710 and a powder feeding and discharging pipe 720 . The powder feeding and discharging pipe 720 is arranged at the bottom of the feeding bin 710 . The feeding bin 710 delivers the powder into the drying hopper 810 through the powder feeding and discharging pipe 720 .
[0093] The aforementioned feeding structure 200 includes a feeding pipe 210 and a feeding bin 220. One end of the feeding pipe 210 is connected to the drying hopper 810, and the other end is connected to the feeding bin 220. The top of the intermediate bin 310 is provided with an intermediate bin feeding port.
[0094] In the present application, both the feed bin 710 and the feeding bin 220 can realize a negative pressure environment or a normal pressure environment through existing technologies. The feed bin 710 also includes a powder feeding pipe 760, one end of which is connected to the feed bin 710, and the other end is used to communicate with a container for holding powder. When the feed bin 710 is in a negative pressure environment, the powder in the container enters the feed bin 710 under the action of the negative pressure and is deposited in the feed bin 710. A powder feeding auger is provided in the aforementioned powder feeding discharge pipe 720, and a powder feeding discharge port is provided on the side of the powder feeding discharge pipe 720. The deposited powder is transported to the drying hopper 810 along the powder feeding discharge pipe 720 under the action of the powder feeding auger.
[0095] Preferably, a first detection sensor group is provided in the feed bin 710, and the first sensor group is used to determine the volume of the powder in the feed bin 710. The first detection sensor group is provided with two sensors, one of which is used to detect whether the feed bin 710 is full, and the other is used to detect whether the feed bin 710 is empty. Specifically, when it is detected that the feed bin 710 is in an empty state, the environment of the feed bin 710 changes to a negative pressure state (the change of the environment of the feed bin 710 will be described later), and the powder in the container enters the feed bin 710 under the action of negative pressure. When it is detected that the feed bin 710 is full, the feed bin 710 switches from a negative pressure environment to a normal pressure environment, and at this time, the powder no longer enters the feed bin 710, and the powder delivery auger works to deliver the powder into the drying hopper 810.
[0096] In this embodiment, the powder first enters the feed bin 710 through the negative pressure environment. Since the feed bin 710 is a closed environment, the dust generation phenomenon of the powder will only occur in the feed bin 710. After the powder is deposited, it is transported to the drying hopper 810 by the powder feeding auger. The auger transportation method is gentler than the negative pressure transportation method and can suppress the dust generation of the powder.
[0097] Furthermore, the aforementioned drying mechanism 820 further includes a drying feed pipe 821 and a drying pipe 822. One end of the drying feed pipe 821 is connected to the drying hopper 810, and the other end is connected to the drying pipe 822. The end of the drying pipe 822 is arranged in the drying hopper 810. A heating element is arranged outside the drying pipe 822. Preferably, the heating unit 823 is a heating belt.
[0098] Specifically, the drying tube 822 includes a drying main tube 822-1 and a drying branch tube 822-2. The drying branch tube 822-2 is arranged at the beginning and the end of the drying main tube 822-1 along the radial direction of the drying main tube 822-1, that is, each drying main tube 822-1 is provided with two drying branch tubes 822-2. A plurality of drying main tubes 822-1 are arranged in parallel in the vertical direction, and adjacent drying main tubes 822-1 are connected through the drying branch tube 822-2, that is, the drying main tube 822-1 located at the top and the drying main tube 822-1 located at the bottom are connected through the drying branch tube 822-2 arranged at the end of the upper drying main tube 822-1 and the drying branch tube 822-2 located at the beginning of the lower drying main tube 822-1, so that the drying tube 822 is S-shaped as a whole. Preferably, the heating belt is wound around the drying main tube 822-1.
[0099] The end of the aforementioned drying feed pipe 821 is connected to the top drying branch pipe 822-2, so that the powder passes through the drying feed pipe 821 and enters the top drying main pipe 822-1 through the drying branch pipe 822-2. Preferably, a drying auger is provided in the drying main pipe 822-1, and each drying auger rotates synchronously. The bottom drying branch pipe 822-2 is connected to the drying hopper 810. A drying feed auger is provided in the drying feed pipe 821.
[0100] The uppermost drying branch pipe 822-2 is also connected to a transition pipe 830, wherein the transition pipe 830 is perpendicular to the axial direction of the uppermost drying branch pipe 822-2, and a transition auger is arranged in the transition pipe 830. The transition pipe 830 is also connected to an overflow pipe 840, and the end of the overflow pipe 840 is connected to the drying hopper 810. The overflow pipe 840 and the drying feed pipe 821 are respectively located on both sides of the uppermost drying branch pipe 822-2.
[0101] In this embodiment, an overflow pipe 840 is provided so that when the drying pipe 822 is blocked, the powder can flow back to the drying hopper 810 through the overflow pipe 840 and then be transported to the drying pipe 822 for drying again through the drying feed pipe 821.
[0102] In order to realize the synchronous rotation of several drying augers, sprocket transmission is adopted between the drying augers. The drying structure 800 also includes a first power mechanism 850, which includes a first output motor 851. The first output motor 851 is transmission-connected to a first reducer 852 with dual output ends. One output end of the first reducer 852 transmits power to the drying feed auger through a first transmission assembly 853 and drives the drying feed auger to rotate. The other output end of the first reducer 852 transmits power to the drying auger through a second transmission assembly 854 and drives the drying auger to rotate. The second transmission assembly 854 is also transmission-connected to a third transmission assembly 855, which transmits power to the transition auger in the transition pipe 830.
[0103] In this embodiment, a specific structure of a first power mechanism 850 is provided, including a first output motor 851 and a first reducer 852, wherein the first reducer 852 is a double-ended reducer.

The aforementioned sub-bin 320 is connected to the sub-bin 320 through the intermediate feed port 312. A vibration mechanism 313 is provided below the guide portion 311, and the vibration mechanism 313 can knock on the guide portion 311 to achieve point vibration and surface vibration of the guide portion 311.
[0105] Since the powder particles are small, they are prone to wall hanging. Although the occurrence of wall hanging can be alleviated by drying, some powder still hangs on the inner wall of the guide part 311 or the intermediate bin 310 during the material distribution process. The phenomenon of some powder hanging on the wall can be alleviated by applying surface vibration to the guide part 311 by the vibration mechanism 313. However, some powder still hangs on the guide part 311, so the vibration mechanism 313 is also required to apply point vibration to the guide part 311 to shock the powder stubbornly attached to the guide part 311 and make the powder slide off.
[0106] In order to ensure that the powder can be smoothly distributed in the distribution structure 300 and the amount of powder in each distribution bin 320 is the same, a first plugging structure 314 is also provided in each distribution bin 320, and the first plugging structure 314 is used to block the intermediate material port 312 corresponding to each distribution bin 320. A second plugging mechanism for blocking the outlet of the distribution bin is also provided at the bottom of each distribution bin 320, and the second plugging mechanism includes a bottom sealing plug 315-1, a first rotating mechanism 315-2 and a first lifting mechanism 315-3. The first lifting mechanism 315-3 is provided on the first rotating mechanism 315-2, and a plug rack is provided on the first lifting mechanism 315-3, and the plug rack is fixed with the same number of bottom sealing plugs 315-1 as the distribution bin 320.
[0107] The second blocking mechanism is also provided with an angle sensor group and a height sensor group 315-4. The angle sensor group is used to detect the angle between the bottom sealing plug 315-1 and the outlet of the material distribution bin on the horizontal plane. The height sensor group 315-4 is used to detect the height difference between the bottom sealing plug 315-1 and the outlet of the material distribution bin in the vertical direction.
[0108] In order to ensure that the powder in the intermediate bin 310 can flow smoothly into the sub-bin 320, the sub-bin 320 is set lower than the intermediate bin 310, so a placement space is formed below the intermediate bin 310, and a placement plate 313-6 is set in the placement space, and the placement plate 313-6 is connected to the side walls of each sub-bin 320. A first rotating mechanism 315-2 is set on the placement plate 313-6. In this embodiment, the first rotating mechanism 315-2 includes a second output motor 524 and a rotating shaft. The rotating shaft is rotatably penetrated through the placement plate 313-6, and the upper end of the rotating shaft is transmission-connected to the second output motor 524. The first lifting mechanism 315-3 is set at the lower end of the rotating shaft and rotates with the rotating shaft. In this embodiment, the first lifting mechanism 315-3 is an electric push rod. The fixed end of the electric push rod is fixedly connected to the lower end of the rotating shaft, and the movable end of the electric push rod is fixedly connected to the plug rack.
[0109] The aforementioned angle sensor group is disposed on the first rotating mechanism 315 - 2 , and the height sensor group 315 - 4 is disposed on the first lifting mechanism 315 - 3 .
[0110] In this embodiment, the plug rack has a plurality of spokes, one end of each spoke is fixed and the other end is free, and the plug rack as a whole is radially centered. The first lifting mechanism 315-3 is fixed at the center of the plug rack, and the bottom sealing plug 315-1 is arranged on one side of the free end of the spoke.
[0111] The aforementioned first blocking structure 314 includes a drainage duct 314-1 and an intermediate sealing plug 314-2 connected to the intermediate material port 312. The drainage duct 314-1 is a hard tube. The intermediate sealing plug 314-2 moves along the length direction of the drainage duct 314-1. When the intermediate sealing plug 314-2 contacts the end of the drainage duct 314-1, the drainage duct 314-1 is blocked, and the intermediate bin 310 cannot be diverted to the sub-bin 320. When the intermediate sealing plug 314-2 is separated from the end of the drainage duct 314-1, the drainage duct 314-1 is unobstructed, and the powder in the intermediate bin 310 flows into the sub-bin 320. The movement of the intermediate sealing plug 314-2 is realized by the intermediate electric push rod 314-3, which is arranged in the sub-bin 320 and connected to the intermediate sealing plug 314-2.
[0112] In order to realize the control of the intermediate electric push rod 314-3, a third full bin sensor group is also provided in each sub-bin 320. The third full bin sensor group includes two sensors, and the third full bin sensor group is used to judge the powder volume in the sub-bin 320 where the third full bin sensor group is located.
[0113] Furthermore, the aforementioned vibration mechanism 313 includes a force-bearing plate 313-1, a marble 313-2 and a first oscillator 313-3. The lower end of the guide portion 311 is provided with an upwardly recessed cavity, the force-bearing plate 313-1 is arranged in the cavity, and the force-bearing plate 313-1 is fixedly connected to the guide portion 311. The first oscillator 313-3 is arranged below the force-bearing plate 313-1, and can apply vibration to the force-bearing plate 313-1. The marble 313-2 is arranged above the force-bearing plate 313-1, and the marble 313-2 can move freely between the force-bearing plate 313-1 and the guide portion 311.
[0114] When the first oscillator 313-3 is working, the power is transmitted to the guide part 311 through the force plate 313-1. At this time, the guide part 311 vibrates as a whole, realizing the surface vibration of the upper surface of the guide part 311. Since the upper surface of the guide part 311 is inclined, a part of the powder slides down along the upper surface of the guide part 311 under the effect of the surface vibration, but a part of the powder still hangs on the upper surface of the guide part 311. At this time, the marble 313-2 is driven by the force plate 313-1, and the marble 313-2 jumps between the guide part 311 and the force plate 313-1, and irregularly knocks the guide part 311, so that the powder hanging on the guide part 311 is subjected to point vibration again, destroying the arched powder.
[0115] Preferably, a second oscillator 322 is further provided on the side wall of the sub-bin 320 .
[0116] Preferably, a third elastic element 313-4 is provided on the bottom surface of the guide portion 311, one end of the third elastic element 313-4 is fixedly connected to the guide portion 311, and the other end is connected to the bottom wall of the intermediate bin 310. The third elastic element 313-4 can increase the vibration amplitude of point vibration and surface vibration. Preferably, a sealing ring 313-5 is provided between the guide portion 311 and the side wall of the intermediate bin 310.
[0117] When the material distribution structure 300 is distributing materials, the third full-bin sensor group in each distribution bin 320 determines whether the distribution bin 320 is full. If it is full, the first blocking structure 314 is used to block the middle material opening 312, and powder is not allowed to enter the distribution bin 320; if it is empty, the middle material opening 312 allows powder to enter the distribution bin 320, and after detecting that the bin is full, the middle material opening 312 is blocked.
[0118] When the material distribution structure 300 feeds the ball mill 110, the first rotating mechanism 315-2 rotates, and the first lifting mechanism 315-3 descends, so that the bottom sealing plug 315-1 forms an angle with the outlet of the material distribution bin on the horizontal plane, and is spaced from the outlet of the material distribution bin in the vertical direction. At this time, the bottom sealing plug 315-1 is separated from the outlet of the material distribution bin, and the powder flows out from the outlet of the material distribution bin without being interfered by the bottom sealing plug 315-1. After the powder flows out, the first rotating mechanism 315-2 rotates, and stops rotating when the angle sensor group detects that the angle between the bottom sealing plug 315-1 and the outlet of the material distribution bin in the horizontal plane is zero, and then the first lifting mechanism 315-3 rises, and stops rising when the height sensor group 315-4 detects that the height difference between the bottom sealing plug 315-1 and the outlet of the material distribution bin in the vertical direction is zero. By using the angle sensor group and the height sensor group 315-4, it is ensured that the bottom sealing plug 315-1 can close the outlet of the material distribution bin to avoid leakage.
[0119] Reference Fig.16 The capping structure 400 includes a first capping plate 410 and a second capping plate 420, wherein the first capping plate 410 is connected to the rotating lifting structure 500, the first capping plate 410 and the second capping plate 420 are arranged concentrically, and the second capping plate 420 can rotate relative to the first capping plate 410. A plurality of tank covers 430 are arranged on the second capping plate 420, and the tank covers 430 are used to seal the ball mill 110, and the tank covers 430 can rotate on the second capping plate 420.
[0120] In this embodiment, the first covering plate 410 and the second covering plate 420 are rotatably connected via a first rotating unit 411 , and the second covering plate 420 and each tank cover 430 are rotatably connected via a second rotating unit 421 .
[0121] When the ball mill 110 rotates, the jar cover 430 is placed on the ball mill 110 , and the jar cover 430 can rotate along with the ball mill 110 due to the second rotating unit 421 , and can revolve along with the ball mill 110 due to the first rotating unit 411 .
[0122] In this embodiment, the first rotating unit 411 and the second rotating unit 421 are both cylindrical self-aligning ball bearings, which can withstand a certain radial load and reduce the assembly accuracy of the tank cover 430 and the ball mill 110.
[0123] Furthermore, a leveling mechanism 440 is provided between the first cover plate 410 and the second cover plate 420. The leveling mechanisms 440 are arranged around the first cover plate 410. The leveling mechanisms 440 include a sleeve 441 and an abutting rod 442. The sleeve 441 is passed through the first cover plate 410. The abutting rod 442 is passed through the sleeve 441. A first elastic element 443 is sleeved on the abutting rod 442. One end of the first elastic element 443 abuts against the second cover plate 420, and the other end abuts against the abutting rod 442. The lower end of the abutting rod 442 abuts against the second cover plate 420. Preferably, a universal ball bearing 444 is provided at the bottom end of the abutting rod 442.
[0124] In the present application, the leveling mechanism 440 is used to maintain the second cover plate 420 in a horizontal state. In the present application, a number of ball mills 110 are filled with powders and grinding balls. Due to slight differences in weight and the offset of the center of gravity, the ball mills 110 will tilt. The cylindrical hole self-aligning bearing is used as the second rotating unit 421. It not only utilizes its relative rotation characteristics to maintain the rotation of the tank cover 430, but also utilizes the characteristics of the cylindrical hole self-aligning ball bearing that can withstand radial loads. When the tank cover 430 is covered on the ball mill 110, the tank cover 430 can be passively deflected, so that the ball mill 110 and the tank cover 430 are easily covered together. Similarly, using the cylindrical hole self-aligning bearing as the second rotating unit 421 can also maintain the passive deflection of the second cover plate 420 as a whole. After the jar cover 430 is taken out from the ball mill 110, the second cover plate 420 is restored to a horizontal state under the adjustment of the leveling mechanism 440, so that the cover structure 400 can be placed on the ball mill 110 again. If there is no cylindrical hole self-aligning ball bearing as the first rotating unit 411 and the second rotating unit 421 and the leveling mechanism 440 is not set, after the cover structure 400 is placed on the ball mill 110 for many times, the second cover plate 420 and the jar cover 430 will gradually tilt and cannot be restored. When the tilt accumulates to a certain extent, the jar cover 430 is likely to be unable to be placed on the ball mill 110.
[0125] A universal ball bearing 444 is disposed at the lower end of the abutting rod 442 , which can convert the sliding friction between the abutting rod 442 and the second covering plate 420 into rolling friction, thereby reducing the resistance to the rotation of the second covering plate 420 relative to the first covering plate 410 .
[0126] The automation system also includes a gantry A.

When the first electromagnetic brake 527 is powered off, the first electromagnetic brake 527 will not hinder the rotation of the first lead screw 521, and at this time, the first lead screw 521 can rotate under the drive of the second output motor 524, thereby adjusting the height of the connecting unit 525.

The aforementioned second electromagnetic brake 634 is fixed on the second chassis 635.
[0133] The aforementioned suction mechanism 640 is screwed to the second lead screw 632 and is slidably connected to the second guide column 633. When the second lead screw 632 rotates, the suction mechanism 640 can be lifted and lowered along the direction of the second guide column 633.

When the fourth output motor 621 is working, it drives the rotating gear 322 to rotate, the outer ring of the bearing rotates synchronously with the rotating gear 322, and the inner ring of the bearing interference fit with the second lead screw 632 does not rotate, so that the fourth output motor 621 only drives the middle plate 631 to rotate.
[0136] Furthermore, the suction mechanism 640 includes a first suction fixing plate 641 and a second suction fixing plate 645 located above the first suction fixing plate 641, and a connecting column is provided between the first suction fixing plate 641 and the second suction fixing plate 645. The first suction fixing plate 641 and the second suction fixing plate 645 are both screwed to the second lead screw 632 and slidably connected to the second guide column 633.
[0137] A first through hole penetrating the first suction fixing plate 641 is provided on the first suction fixing plate 641, a first rotating ring 642 is provided above the first through hole, a second rotating ring 643 is provided above the first rotating ring 642, the first rotating ring 642 and the second rotating ring 643 are provided concentrically, and the first rotating ring 642 and the second rotating ring 643 can rotate independently, the inner ring of the first rotating ring 642 is circular, and the inner ring of the second rotating ring 643 is a waist-shaped groove 643-1.

Under the action of the first rotating ring 642, the second rotating ring 643 and the eccentric plate 644, the material suction main pipe 610 swings around the ball joint connection, and the swing trajectory of the lower end of the material suction main pipe 610 is as shown in FIG. Fig.14 As shown by the dotted line in .
[0139] Preferably, the top end of the suction main pipe 610 is connected to the second suction fixing plate 645 via a joint bearing 646 .
[0140] A pushing mechanism 650 is provided at the bottom of the first rotating ring 642, and the pushing mechanism 650 includes a moving plate 651. A second elastic element 652 is provided between the moving plate 651 and the first rotating ring 642. Under the action of the second elastic element 652, the moving plate 651 abuts the suction main pipe 610 against a semicircular ring of the waist-shaped groove 643-1.
[0141] Specifically, a fixed plate is provided at the bottom of the first rotating ring 642, and a half-waist-shaped groove is opened on the fixed plate; another outer half-waist-shaped groove is opened correspondingly on the movable plate 651, and spaced fixed ears are provided on the fixed plate, and a movable ear is provided on the movable plate 651, and the movable ear is located between the two fixed ears, and a guide rod is provided on the two fixed ears, and the guide rod is passed through the movable ear.

Under the action of the second elastic unit, the center distance between the two half-waist-shaped grooves can be changed.
[0142] When the suction pipe 610 is inserted into the ball mill 110 one by one, it swings in the ball mill 110. Since there are grinding balls in the ball mill 110, the suction pipe 610 will jump in the opposite direction of the position of the suction pipe 610 after hitting the grinding balls, causing leakage of the grinding ball position. Under the action of the pushing mechanism 650, the moving plate 651 pushes the suction pipe 610 back to its original position, so that the suction pipe 610 avoids the grinding balls and does not leak the grinding balls.
[0143] In this embodiment, a driving structure is provided for the rotation of the first rotating ring 642 and the second rotating ring 643. The first rotating ring 642 and the second rotating ring 643 are driven by a second power mechanism, and the second power mechanism includes a fifth output motor 661 and a worm gear reducer 622. The side surfaces of the first rotating ring 642 and the second rotating ring 643 are provided with teeth. The fifth output motor 661 transmits power to the first rotating ring 642 through the fourth transmission assembly.

[0146] A rotating bearing is disposed between the first rotating ring 642 and the second rotating ring 643 , and the inner and outer rings of the rotating bearing are fixedly connected to the first rotating ring 642 and the second rotating ring 643 , respectively.
[0147] Furthermore, an eccentric waist-shaped hole 644-2 is provided on the eccentric plate 644, and the eccentric plate 644 is fixed to the second rotating ring 643 by bolts.

Both the first suction material positioning sensor 670 and the second suction material positioning sensor 680 are micro proximity switches.
[0149] As mentioned above, the ball mill 110 will be tilted to a certain extent when it is loaded with grinding balls and powder. When the suction main pipe 610 is sucking materials, the maximum distance between the bottom end of the suction main pipe 610 and the center of the ball mill 110 is the radius of the ball mill 110. When the suction main pipe 610 is inserted into the ball mill 110 again, it is easy for the suction main pipe 610 to abut against the upper edge of the ball mill 110 and cannot be inserted into the ball mill 110 due to the inclination of the ball mill 110. At this time, the first suction positioning sensor 670 and the second suction positioning sensor 680 limit the suction main pipe 610 to a position where it stops swinging, which can avoid the situation where it cannot be inserted. Under the restriction of the first suction positioning sensor 670 and the second suction positioning sensor 680, the distance between the bottom end of the suction main pipe 610 and the center of the ball mill 110 when it stops swinging is less than the radius of the ball mill 110.

When the first negative pressure mechanism 730 is working, it can be connected with the first negative pressure pipe 750 through the first main negative pressure pipe 740 to form a negative pressure environment in the feed bin 710, or it can be connected with the second negative pressure pipe 960 through the first main negative pressure pipe 740. At this time, the first negative pressure mechanism 730 is indirectly connected with the suction main pipe 610, so that the suction main pipe 610 absorbs the powder in the ball mill 110.
[0154] The screening structure 900 further includes a secondary processing box 970, which is connected to a feed branch pipe 980, and the feed branch pipe 980 is connected to the feed pipe 210. The feed bin 220 is also connected to a second negative pressure mechanism 230. A second three-way valve is provided between the feed branch pipe 980 and the feed pipe 210, and the second three-way valve controls the on-off of the feed branch pipe 980 and the feed pipe 210. A feeding port is provided on the secondary processing box 970.
[0155] After screening in the screening box 910, the powders that meet the particle size are retained at the bottom of the screening box 910, while the powders that do not meet the particle size are transported to the corresponding storage box 950 by the first screening pipe 930 and the second screening pipe 940. The worker manually transfers the powders in the storage box 950 to the secondary processing box 970.
[0156] When the feeding structure 200 is feeding, the second three-way valve is switched to draw the powder in the secondary processing box 970 into the feeding hopper.
[0157] The advantages of this application are:
[0158] First, the powder is in a sealed environment during transportation, which can suppress the generation of dust.
[0159] Second, negative pressure adsorption combined with auger transportation is adopted in the feeding structure 700 and the feeding structure 200. The powder is deposited in the feeding bin 710 and the feeding bin 220 through negative pressure absorption, and then is sent into the drying hopper 810 and the dividing structure 300 through the action of the feeding auger and the feeding auger, which improves the transportation efficiency and avoids the generation of dust.
[0160] Third, the present application realizes the fully automated operation of powder feeding, drying, material separation, grinding and material suction, which can reduce human intervention and is more suitable for industrial production.
[0161] Fourth, a drying structure 800 dedicated to powder is provided, which can perform cyclic drying and is provided with an overflow pipe 840, which solves the problem that powder is easily blocked in the tubular drying device. At the same time, the powder is transported by the drying auger in the drying mechanism 820, and the powder keeps rolling, which can improve the drying efficiency.
[0162] Fifth, the intermediate bin 310 is provided with a vibration mechanism 313, which can effectively alleviate the phenomenon of dust hanging on the wall of the guide part 311. Since the intermediate bin 310 mainly slides by the gravity of the powder itself when distributing materials to the distribution bin 320, although the powder has undergone a drying step to reduce the probability of hanging on the wall, it is inevitable that the powder will still hang on the wall. At this time, the point vibration and surface vibration of the vibration mechanism 313 can effectively shake off the powder hanging on the wall of the guide part 311, solving the problem of the intermediate bin easily hanging on the wall, and ensuring that when the intermediate bin 310 distributes materials to the distribution bin 320, the intermediate material port 312 is blocked.
[0163] Sixth, the material distribution structure 300 and the capping structure 400 are both driven by the rotating lifting structure 500, which makes the present application more streamlined, requires less space, and reduces the cost of the present application.
[0164] Seventh, the upper end of the rotary lifting structure 500 is fixed on the gantry A, and the first lead screw 521 is clamped by the first electromagnetic brake 527 to prevent the rotary lifting structure 500 from shaking due to the grinding vibration of the ball mill when the capping structure 400 is covered on the ball mill.
[0165] Eighth, the sealing structure 400 is provided with a first rotating unit 411 and a second rotating unit 421, so that the sealing can revolve and rotate along with the ball mill jar, and there is no need to cover the ball mill jars one by one with the jar cover 430.
[0166] Ninth, the cover structure 400 has a leveling unit 440, which automatically levels the second cover plate 420 after each opening of the cover, so as to prevent the jar cover 430 from being unable to be covered on the ball mill jar after multiple uses.
[0167] Tenth, in the suction structure 600 , the suction main pipe 610 is constantly swinging, which can cleanly absorb the powder in the ball mill 110 . Meanwhile, the pushing mechanism 650 is provided to prevent the suction main pipe 610 from jumping.
[0168] Eleventh, a screening structure 900 is provided to screen the ground powder and re-grind the powder with larger particles.
[0169] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
