[0082] To make the technical problems, technical solutions and advantages of the present application clearer, specific embodiments will be described in detail below with reference to the drawings.

[0083] Embodiments of the present application provide an automatic system suitable for a planetary ball mill, referring to Figures 1-16 As shown in the drawings, the automatic system comprises a planetary ball mill 100, a feeding structure 200, a distributing structure 300, a capping structure 400, a rotating lifting structure 500, and a suction structure 600. The planetary ball mill 100 comprises a plurality of ball jars 110, which can rotate around their own axes and also revolve around the axis of the planetary ball mill 100. The feeding structure 200 is used to feed the distributing structure 300. The distributing structure 300 comprises an intermediate bin 310 and a distributing bin 320. The intermediate bin 310 is connected to the feeding structure 200 to receive the feed from the feeding structure 200. The distributing bin 320 is in communication with the intermediate bin 310, and the powder passing through the intermediate bin 310 is distributed into the distributing bin 320. The distributing bin 320 can discharge the powder into the ball jars 110 one by one through the distributing bin outlet at the bottom. The capping structure 400 is used to cap the ball jars 110 and revolve and rotate with the ball jars 110. The distributing structure 300 and the capping structure 400 are arranged on the rotating lifting structure 500 and rotate and lift under the drive of the rotating lifting structure 500. The suction structure 600 comprises a suction pipe, which is used to suck the ground powder in the ball jars 110 out of the ball jars 110.

[0084] The automatic system comprises a first state, a second state and a third state. When the automatic system is in the first state, the distribution structure 300 is driven by the rotary lifting structure 500 to rotate to the lower side of the feeding structure 200 and then moves upward, the intermediate bin 310 receives the feeding of the feeding structure 200, and the powder is distributed to each distribution bin 320 after entering the intermediate bin 310, so as to prepare for feeding the ball mill tank 110. When the distribution structure 300 moves upward, the cover structure 400 connected with the rotary lifting structure 500 also moves upward synchronously, and at this time, the cover structure 400 is separated from the ball mill tank 110, and the suction pipe is inserted into the ball mill tank 110 to suck out the ground powder.

[0085] When the automatic system is in the second state, the suction pipe sucks out all the ground powder in the ball mill tank 110 and removes it from the ball mill tank 110, at this time, the distribution structure 300 moves downward after rotating to the upper side of the ball mill tank 110 and feeds the powder to be ground into the ball mill tank 110. At this time, the cover structure 400 is driven by the rotary lifting structure 500 to move to another place to avoid interference of the cover structure 400 with the feeding of the distribution structure 300.

[0086] When the automatic system is in the third state, the cover structure 400 moves to the upper side of the ball mill tank 110 and moves downward until the cover structure 400 covers the ball mill tank 110, at this time, the planetary ball mill 100 works to grind the powder in the ball mill tank 110.

[0087] The automatic system sequentially switches between the first state, the second state and the third state to complete the grinding of the powder once.

[0088] In the present application, by designing an automatic system suitable for the planetary ball mill, the feeding before grinding and the suction after grinding of the powder can be automatically processed without manual intervention, which can effectively improve the degree of automation. At the same time, the powder is transported in a closed condition, which can effectively avoid the dust phenomenon.

[0089] The automatic system further comprises a feeding structure 700 and a drying structure 800.

[0090] Referring to Figures 2-5 The drying structure 800 comprises a drying hopper 810 and a drying mechanism 820, the initial end and the terminal end of the drying mechanism 820 are arranged in the drying hopper 810, the powder enters the drying mechanism 820 from the initial end for drying, and is discharged from the terminal end to the drying hopper 810, and the water content of the powder can be reduced through multiple cycles.

[0091] Since the particle size of the powder is small, the powder will produce wall hanging phenomenon in the transportation process, therefore, the powder is dried before entering the feeding structure 200 for transportation, which can effectively reduce the wall hanging phenomenon. In the present application, the water content of the powder is reduced by multiple circulation, on the one hand, the powder is dried, the water content is reduced, on the other hand, the space occupied by the drying structure 800 is reduced.

[0092] The foregoing feeding structure 700 includes a feeding bin 710 and a powder feeding outlet pipe 720, the powder feeding outlet pipe 720 is arranged at the bottom of the feeding bin 710, the feeding bin 710 sends the powder into the drying hopper 810 through the powder feeding outlet pipe 720.

[0093] The foregoing feeding structure 200 includes a feeding feeding pipe 210 and a feeding bin 220, one end of the feeding feeding pipe 210 is in communication with the drying hopper 810, the other end is in communication with the feeding bin 220. The top end of the intermediate bin 310 is provided with an intermediate bin feeding port.

[0094] In the present application, the feeding bin 710 and the feeding bin 220 can realize negative pressure environment or normal pressure environment by the existing technology. The feeding bin 710 further includes a powder feeding pipe 760, one end of the powder feeding pipe 760 is in communication with the feeding bin 710, the other end is used for being in communication with a container containing powder. When the feeding bin 710 is in a negative pressure environment, the powder in the container enters the feeding bin 710 under the action of negative pressure and deposits in the feeding bin 710. The foregoing powder feeding outlet pipe 720 is provided with a powder feeding auger, the side of the powder feeding outlet pipe 720 is provided with a powder feeding outlet, the deposited powder is transported into the drying hopper 810 along the powder feeding outlet pipe 720 under the action of the powder feeding auger.

[0095] Preferably, a first detection sensor group is arranged in the feeding bin 710, the first sensor group is used for determining the volume of the powder in the feeding bin 710. The first detection sensor group is provided with two sensors, one of which is used for detecting whether the feeding bin 710 is full, and the other is used for detecting whether the feeding bin 710 is empty. Specifically, when it is detected that the feeding bin 710 is in an empty bin state, the environment of the feeding bin 710 changes to a negative pressure state (the change of the environment of the feeding bin 710 will be described later), the powder in the container enters the feeding bin 710 under the action of negative pressure. When it is detected that the feeding bin 710 is full, the feeding bin 710 is switched from a negative pressure environment to a normal pressure environment, at this time, the powder no longer enters the feeding bin 710, at this time, the powder feeding auger works to send the powder into the drying hopper 810.

[0096] In the embodiment, the powder is first introduced into the feeding bin 710 under the action of the negative pressure environment. Since the feeding bin 710 is a closed environment, the dust raising phenomenon of the powder only occurs in the feeding bin 710. After the powder is deposited, the powder is transported to the drying hopper 810 by the powder conveying auger. The powder conveying auger is more gentle than the negative pressure conveying mode, and can inhibit the dust raising of the powder.

[0097] Further, the drying mechanism 820 further comprises a drying feeding pipe 821 and a drying pipe 822. One end of the drying feeding pipe 821 is in communication with the drying hopper 810, and the other end is in communication with the drying pipe 822. The drying pipe 822 is arranged in the drying hopper 810. A heating unit is arranged outside the drying pipe 822. Preferably, the heating unit 823 is a heating belt.

[0098] Specifically, the drying pipe 822 comprises a drying main pipe 822-1 and a drying branch pipe 822-2. The drying branch pipe 822-2 is arranged at the beginning end and the end end of the drying main pipe 822-1 along the radial direction of the drying main pipe 822-1, that is, two drying branch pipes 822-2 are arranged on each drying main pipe 822-1. A plurality of drying main pipes 822-1 are arranged in parallel along the vertical direction. The adjacent drying main pipes 822-1 are communicated by the drying branch pipe 822-2, that is, the upper drying main pipe 822-1 and the lower drying main pipe 822-1 are communicated by the drying branch pipe 822-2 arranged at the end end of the upper drying main pipe 822-1 and the drying branch pipe 822-2 arranged at the beginning end of the lower drying main pipe 822-1, so that the drying pipe 822 as a whole presents an S shape. Preferably, the heating belt is wound on the drying main pipe 822-1.

[0099] The end of the drying feeding pipe 821 is in communication with the uppermost drying branch pipe 822-2, so that the powder enters the uppermost drying main pipe 822-1 from the drying branch pipe 822-2 after passing through the drying feeding pipe 821. Preferably, the drying main pipe 822-1 is provided with a drying auger, and each drying auger rotates synchronously. The lowermost drying branch pipe 822-2 is in communication with the drying hopper 810. The drying feeding pipe 821 is provided with a drying feeding auger.

[0100] The uppermost drying branch pipe 822-2 is further communicated with a transition pipe 830, wherein the transition pipe 830 is perpendicular to the axis direction of the uppermost drying branch pipe 822-2. A transition auger is arranged in the transition pipe 830. The transition pipe 830 is further communicated with an overflow pipe 840, and the end of the overflow pipe 840 is in communication with the drying hopper 810. The overflow pipe 840 and the drying feeding pipe 821 are respectively located on the two sides of the uppermost drying branch pipe 822-2.

[0101] In the embodiment, the overflow pipe 840 is arranged to make the dry pipe 822 backflow to the dry hopper 810 through the overflow pipe 840 when the dry pipe 822 is blocked, and then the powder is transported to the dry pipe 822 again by the dry feeding pipe 821 for drying.

[0102] In order to realize the synchronous rotation of the dry augers, chain wheels are used to drive the dry augers. The drying structure 800 further comprises a first power mechanism 850, which comprises a first output motor 851, a double-output first speed reducer 852 connected with the first output motor 851, one output end of the first speed reducer 852 being connected with a first transmission assembly 853 to transmit power to the dry feeding auger and drive the dry feeding auger to rotate. The other output end of the first speed reducer 852 is connected with a second transmission assembly 854 to transmit power to the dry auger and drive the dry auger to rotate. A third transmission assembly 855 is further connected with the second transmission assembly 854 to transmit power to the transition auger in the transition pipe 830.

[0103] In the embodiment, a specific structure of the first power mechanism 850 is provided, which comprises the first output motor 851 and the double-end first speed reducer 852. The first transmission assembly 853 comprises a first bevel gear arranged on one output end of the first speed reducer 852, the first bevel gear being engaged with a second bevel gear, the second bevel gear being connected with a first universal shaft, the other end of the first universal shaft being connected with a first worm gear, the worm of the first worm gear being connected with the first universal shaft, and the turbine of the first worm gear being fixed on the rotating shaft of the dry feeding auger.

The third transmission assembly 855 comprises a third bevel gear arranged on the dry auger, the third bevel gear being engaged with a fourth bevel gear, and the fourth bevel gear being connected with the chain wheel of the rotating shaft of the transition auger.

[0104] Referring to Figure 6 and 7The intermediate bin 310 is a cylinder with an intermediate bin inlet at the upper end, and an intermediate outlet 312 is arranged on the side of the cylinder. The intermediate outlet 312 is arranged around the cylinder. A guide part 311 is further arranged in the intermediate bin 310, and the guide part 311 is located at the bottom of the intermediate bin 310. The guide part 311 is a conical structure. The guide part 311 is arranged directly below the intermediate bin inlet, and the upper surface of the guide part 311 is conical. The aforementioned distribution bin 320 is in communication with the distribution bin 320 through the intermediate outlet 312. A vibration mechanism 313 is arranged below the guide part 311, and the vibration mechanism 313 can knock the guide part 311 to achieve point vibration and surface vibration of the guide part 311.

[0105] Due to the small size of the powder particles, wall sticking phenomenon is easy to occur. Although wall sticking can be alleviated by drying, during the distribution process, part of the powder still sticks to the inner wall of the guide part 311 or the intermediate bin 310. The surface vibration of the guide part 311 by the vibration mechanism 313 can alleviate the wall sticking phenomenon of part of the powder. However, powder still sticks to the guide part 311, so the vibration mechanism 313 needs to apply point vibration to the guide part 311 to shock the stubbornly adhered powder on the guide part 311, so that the powder slides off.

[0106] In order to ensure that the powder can be smoothly distributed in the distribution structure 300 and ensure that the amount of powder in each distribution bin 320 is the same, a first blocking structure 314 is further arranged in each distribution bin 320, and the first blocking structure 314 is used to block the corresponding intermediate outlet 312 of each distribution bin 320. A second blocking mechanism for blocking the outlet of the distribution bin is further arranged at the bottom of each distribution bin 320, and the second blocking 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 arranged on the first rotating mechanism 315-2, and a plug holder is arranged on the first lifting mechanism 315-3, and the plug holder is fixed with the same number of bottom sealing plugs 315-1 as the number of distribution bins 320.

[0107] An angle sensor group and a height sensor group 315-4 are further arranged on the second blocking mechanism, the angle sensor group is used to detect the angle of the bottom sealing plug 315-1 and the outlet of the distribution bin in the horizontal plane. The height sensor group 315-4 is used to detect the height difference of the bottom sealing plug 315-1 and the outlet of the distribution bin in the vertical direction.

[0108] In order to ensure that the powder in the intermediate bin 310 can flow smoothly into the distribution bin 320, the distribution bin 320 is lower than the intermediate bin 310, so that a placement space is formed below the intermediate bin 310, and the placement plate 313-6 is arranged in the placement space and connected with the side wall of each distribution bin 320. The first rotating mechanism 315-2 is arranged on the placement plate 313-6, and in the embodiment, the first rotating mechanism 315-2 includes a second output motor 524 and a rotating shaft, the rotating shaft is rotatably arranged in the placement plate 313-6, and the upper end of the rotating shaft is in transmission connection with the second output motor 524. The first lifting mechanism 315-3 is arranged at the lower end of the rotating shaft and rotates with the rotating shaft. In the embodiment, the first lifting mechanism 315-3 is an electric push rod. The fixed end of the electric push rod is fixedly connected with the lower end of the rotating shaft, and the movable end of the electric push rod is fixedly connected with the plug holder.

[0109] The aforementioned angle sensor group is arranged on the first rotating mechanism 315-2, and the height sensor group 315-4 is arranged on the first lifting mechanism 315-3.

[0110] In the embodiment, the plug holder has a plurality of spokes, one end of the plurality of spokes is fixed, and the other end is a free end, and the plug holder as a whole presents a central radial shape. The first lifting mechanism 315-3 is fixed at the center of the plug holder, and the bottom sealing plug 315-1 is arranged on one side of the free end of the spoke.

[0111] The aforementioned first plugging structure 314 includes a dredging pipe 314-1 in communication with the intermediate material port 312 and an intermediate sealing plug 314-2, the dredging pipe 314-1 is a hard pipe, the intermediate sealing plug 314-2 moves along the length direction of the dredging pipe 314-1, when the intermediate sealing plug 314-2 is in contact with the end of the dredging pipe 314-1, the dredging pipe 314-1 is plugged, at this time, the intermediate bin 310 cannot distribute to the distribution bin 320. When the intermediate sealing plug 314-2 is separated from the end of the dredging pipe 314-1, the dredging pipe 314-1 is unobstructed, and the powder in the intermediate bin 310 flows into the distribution bin 320. The movement of the intermediate sealing plug 314-2 is realized through the intermediate electric push rod 314-3, and the intermediate electric push rod 314-3 is arranged in the distribution bin 320 and connected with 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 further arranged in each distribution bin 320, the third full bin sensor group includes two sensors, and the third full bin sensor group is used to judge the volume of the powder in the distribution bin 320 where the third full bin sensor group is arranged.

[0113] Further, the aforementioned vibrating mechanism 313 comprises a force receiving plate 313-1, a ball 313-2 and a first oscillator 313-3. The lower end of the guide portion 311 is provided with a cavity concave upward, the force receiving plate 313-1 is arranged in the cavity, and the force receiving plate 313-1 is fixedly connected with the guide portion 311. The first oscillator 313-3 is arranged below the force receiving plate 313-1 and can apply vibration to the force receiving plate 313-1. The ball 313-2 is arranged above the force receiving plate 313-1, and the ball 313-2 can move freely between the force receiving plate 313-1 and the guide portion 311.

[0114] When the first oscillator 313-3 works, power is transmitted to the guide portion 311 through the force receiving plate 313-1, at this time, the guide portion 311 as a whole vibrates, realizing the surface vibration of the upper surface of the guide portion 311. Since the upper surface of the guide portion 311 is inclined, under the action of surface vibration, part of the powder slides along the upper surface of the guide portion 311, but part of the powder still hangs on the upper surface of the guide portion 311. At this time, the ball 313-2 is driven by the force receiving plate 313-1, and the ball 313-2 jumps between the guide portion 311 and the force receiving plate 313-1, irregularly knocking the guide portion 311, so that the powder hanging on the guide portion 311 is subjected to point vibration again, destroying the arching powder.

[0115] Preferably, a second oscillator 322 is further arranged on the side wall of the distribution bin 320.

[0116] Preferably, a third elastic element 313-4 is arranged on the bottom surface of the guide portion 311, one end of the third elastic element 313-4 is fixedly connected with the guide portion 311, and the other end is connected with 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 arranged between the guide portion 311 and the side wall of the intermediate bin 310.

[0117] When the distribution structure 300 is distributing, the third full bin sensor group in each distribution bin 320 judges whether the distribution bin 320 where the third full bin sensor group is located is a full bin. If it is a full bin, the first blocking structure 314 is used to block the intermediate material port 312, so that the powder is not allowed to enter the distribution bin 320; if it is an empty bin, the intermediate material port 312 allows the powder to enter the distribution bin 320. After detecting the full bin, the intermediate material port 312 is blocked.

[0118] When the powder distribution structure 300 is used to feed the ball mill tank 110, the first rotating mechanism 315-2 rotates, and the first lifting mechanism 315-3 descends, so that the bottom sealing plug 315-1 is separated from the powder distribution tank outlet in the horizontal direction and the vertical direction. At this time, the bottom sealing plug 315-1 is separated from the powder distribution tank outlet, and the powder flows out from the powder distribution tank outlet without being interfered by the bottom sealing plug 315-1. After the powder flow is completed, the first rotating mechanism 315-2 rotates, and when the angle sensor group detects that the angle between the bottom sealing plug 315-1 and the powder distribution tank outlet in the horizontal direction is zero, the rotation is stopped, and then the first lifting mechanism 315-3 rises, and when the height sensor group 315-4 detects that the height difference between the bottom sealing plug 315-1 and the powder distribution tank outlet in the vertical direction is zero, the rising is stopped. Through the use of the angle sensor group and the height sensor group 315-4, it is ensured that the bottom sealing plug 315-1 can seal the powder distribution tank outlet, so as to avoid the leakage of the powder.

[0119] With reference to Figure 16 The cover structure 400 includes a first cover plate 410 and a second cover plate 420, wherein the first cover plate 410 is connected with the rotating and lifting structure 500, the first cover plate 410 and the second cover plate 420 are concentrically arranged, and the second cover plate 420 can rotate relative to the first cover plate 410. A plurality of tank covers 430 are arranged on the second cover plate 420, and the tank covers 430 are used to seal the ball mill tank 110 and can rotate on the second cover plate 420.

[0120] In the embodiment, the first cover plate 410 and the second cover plate 420 are rotationally connected through a first rotating unit 411, and the second cover plate 420 and each tank cover 430 are rotationally connected through a second rotating unit 421.

[0121] When the ball mill tank 110 rotates, the tank cover 430 is arranged on the ball mill tank 110, and the tank cover 430 can rotate with the ball mill tank 110 due to the second rotating unit 421 and can revolve with the ball mill tank 110 due to the first rotating unit 411.

[0122] In the embodiment, the first rotating unit 411 and the second rotating unit 421 are both cylindrical hole self-aligning ball bearings, which can bear a certain radial load and reduce the assembly precision of the tank cover 430 and the ball mill tank 110.

[0123] Further, a leveling mechanism 440 is arranged between the first cover plate 410 and the second cover plate 420, and a plurality of leveling mechanisms 440 are arranged on the first cover plate 410. The leveling mechanism 440 comprises a sleeve 441 and an abutting rod 442. The sleeve 441 is arranged on the first cover plate 410, and the abutting rod 442 is arranged in the sleeve 441. A first elastic element 443 is arranged on the abutting rod 442. One end of the first elastic element 443 abuts against the second cover plate 420, and the other end of the first elastic element 443 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 arranged 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 plurality of ball mills 110 are filled with powder and grinding balls. Due to slight differences in weight and deviation of the center of gravity, the ball mills 110 will tilt. The cylindrical hole aligning bearing is used as the second rotating unit 421. The cylindrical hole aligning bearing is used to maintain the rotation of the tank cover 430 and to bear the radial load when the tank cover 430 covers the ball mill 110. When the tank cover 430 covers the ball mill 110, the tank cover 430 can passively tilt, so that the ball mill 110 and the tank cover 430 are easily covered together. Similarly, the cylindrical hole aligning bearing as the second rotating unit 421 can also maintain the passive tilt of the second cover plate 420. After the tank cover 430 is removed from the ball mill 110, the second cover plate 420 returns to the horizontal state under the adjustment of the leveling mechanism 440, which facilitates the re-covering of the cover structure 400 on the ball mill 110. Without the cylindrical hole aligning bearing as the first rotating unit 411 and the second rotating unit 421 and the leveling mechanism 440, the second cover plate 420 and the tank cover 430 will gradually tilt after the cover structure 400 is repeatedly covered on the ball mill 110, and cannot be restored. When the accumulation reaches a certain degree, the tank cover 430 cannot be covered on the ball mill 110.

[0125] The abutting rod 442 is provided with a universal ball bearing 444 at the lower end, which can convert the sliding friction between the abutting rod 442 and the second cover plate 420 into rolling friction, thereby reducing the resistance of the second cover plate 420 relative to the first cover plate 410.

The inner ring of the bearing which is interference-fitted with the second lead screw 632 does not rotate, so as to realize the purpose that the fourth output motor 621 only drives the middle disc 631 to rotate.

[0136] Further, the aforementioned suction mechanism 640 comprises 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 arranged between the first suction fixing plate 641 and the second suction fixing plate 645.

[0142] When the material suction main pipe 610 is inserted into the ball mill jar 110 one by one and swings in the ball mill jar 110, the material suction main pipe 610 will jump in the opposite direction of the position of the material suction main pipe 610 when the material suction main pipe 610 encounters the grinding ball, causing the grinding ball position to be missed, and under the action of the pushing mechanism 650, the moving plate 651 pushes the material suction main pipe 610 back to the original position, so that the material suction main pipe 610 avoids the grinding ball and does not miss the grinding ball position.

[0143] In the 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.

When the suction main pipe 610 is inserted into the ball mill tank 110 again, due to the inclination of the ball mill tank 110, the suction main pipe 610 is easily abutted against the upper edge of the ball mill tank 110 and cannot be inserted into the ball mill tank 110. At this time, the first suction positioning sensor 670 and the second suction positioning sensor 680 limit the position of the suction main pipe 610 when it stops swinging, so that the situation of being unable to be inserted can be avoided.

A second three-way valve is arranged between the feeding feed branch pipe 980 and the feeding feed pipe 210, and the second three-way valve controls the opening and closing of the feeding feed branch pipe 980 and the feeding feed pipe 210. The secondary processing box 970 is provided with a feeding port.

[0155] After screening in the screening box 910, the powder meeting the particle size is retained at the bottom of the screening box 910, and the powder not meeting the particle size is transported into the corresponding storage box 950 through the first and second screening pipes 930 and 940 respectively. The worker manually transfers the powder in the storage box 950 into the secondary processing box 970.

[0156] When the feeding structure 200 feeds, the second three-way valve is switched to suck the powder in the secondary processing box 970 into the feeding hopper.

[0157] The advantages of the present application are:

[0158] Firstly, the powder is in a sealed environment during transportation, which can inhibit the generation of dust.

[0159] Secondly, the negative pressure adsorption combined with the screw conveyor is used 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 suction, and then is sent into the drying hopper 810 and the distribution structure 300 through the feeding screw conveyor and the feeding screw conveyor, which improves the conveying efficiency and avoids the generation of dust.

[0160] Thirdly, the present application realizes the full automation of powder feeding, drying, distribution, grinding and suction, which can reduce the intervention of manpower and is more suitable for industrial production.

[0161] Fourthly, a drying structure 800 special for powder is provided, which can perform cyclic drying and is provided with an overflow pipe 840, solving the problem of blockage of the powder in the tubular drying device. Meanwhile, the powder is transported by the drying screw conveyor in the drying mechanism 820, and the powder continuously rolls, which can improve the drying efficiency.

[0162] Fifthly, the intermediate bin 310 is provided with a vibration mechanism 313, which can effectively alleviate the phenomenon of powder wall-hanging on the guide part 311. Since the distribution of the intermediate bin 310 to the distribution bin 320 is mainly through the gravity of the powder, although the probability of wall-hanging is reduced after the drying step, the wall-hanging of the powder is inevitable. At this time, the point vibration and surface vibration of the vibration mechanism 313 can effectively vibrate the powder wall-hanging on the guide part 311, solving the problem of easy wall-hanging of the intermediate bin and ensuring that the intermediate bin 310 does not block the intermediate opening 312 when distributing to the distribution bin 320.

[0163] Sixthly, the distribution structure 300 and the cover structure 400 are driven by the rotary lifting structure 500, so that the present application is more compact, 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 electromagnetic brake 527 is used to clamp the first lead screw 521, so that the rotary lifting structure 500 is prevented from shaking due to the grinding vibration of the ball mill tank when the cover structure 400 is covered on the ball mill tank.

[0165] Eighth, the first rotating unit 411 and the second rotating unit 421 are arranged in the cover structure 400, so that the cover can revolve and rotate with the ball mill tank, and the ball mill tank does not need to be covered by the tank cover 430 one by one.

[0166] Ninth, the cover structure 400 has a leveling unit 440, which automatically levels the second cover plate 420 after each opening, so that the tank cover 430 can be covered on the ball mill tank after being used for many times.

[0167] Tenth, in the suction structure 600, the suction main pipe 610 continuously swings, so that the powder in the ball mill tank 110 can be completely sucked, and the pushing mechanism 650 is arranged to prevent the suction main pipe 610 from jumping.

[0168] Eleventh, the screening structure 900 is arranged to screen the ground powder, and the powder with large particles is re-ground.

[0169] The above describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
