Description

Technical Field

[0001] This utility model mainly relates to the field of sample preparation technology, specifically a fully automatic grinding and tableting machine. Background Technology

[0002] In the cement industry, sample tablets are typically made manually using grinding mills and tablet presses. To achieve efficient tablet pressing, existing practitioners have designed automatic grinding and tablet pressing machines. For example, Chinese patent application CN202120335564.6 discloses a sample tablet making device for material testing and analysis. This device includes a quantitative mechanism, a grinding mechanism, a tablet pressing mechanism, a tablet punching mechanism, an automatic steel ring storage and retrieval mechanism, a transfer mechanism, and a dosing mechanism. All of these components are mounted on a frame. For example, CN201820189129.5 discloses an automatic tablet press, including a shell, a feeding port, a grinding box, an automatic grinder, a feeding pipe, a hydraulic pump station, a hydraulic cylinder, a press, an air gripper, a turntable, a conveyor, and a pressure mold. The press is fixed to the shell with screws. The air gripper, hydraulic pump station, and hydraulic cylinder are all fixed to the press. The hydraulic cylinder is located at the bottom of the press, and the conveyor is located below the air gripper. The turntable is located below the press, air gripper, and conveyor. The turntable has four openings. One opening holds the pressure mold, and another opening holds the dust collection mold. One end of the feeding port is fixedly connected to the shell, and the other end is fixed to the grinding box with a clamp. The grinding box is fixed above the automatic grinder, and one end of the automatic grinder is also fixedly connected to the shell. One end of the feeding pipe is clamped to the grinding box, and the other end extends above the turntable.

[0003] Although the above solutions can achieve automatic sample production, they still have the following drawbacks:

[0004] After sample preparation, the internal components of the equipment still require manual cleaning, which is time-consuming, labor-intensive, and inefficient. Furthermore, the areas requiring cleaning after sample pressing are still inside the equipment, necessitating machine shutdown and disassembly of parts, making manual cleaning extremely difficult. Manual operation may lead to negligence and incomplete cleaning, resulting in cross-contamination of samples, and the inhalation of dust during cleaning poses adverse health risks. Therefore, achieving rapid and automatic cleaning of all components in an automated grinding and pressing machine is a technical problem urgently needing to be solved by those skilled in the art.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] like Figure 1 and Figure 13 As shown, this embodiment discloses a fully automatic grinding and tableting machine, including a frame 1. The frame 1 is equipped with a rotary grinding device 2, a powder tableting device 3, a sample cleaning and crushing device 4, a steel ring conveying device 5, and a dust removal system 6. The dust removal system 6 includes a dust collection host, a main pipeline 61, multiple branch pipelines 62, and a control device. One end of the branch pipeline 62 is connected to the main pipeline 61 through a valve 63, and the other end of the branch pipeline 62 is connected to any one or more of the rotary grinding device 2, the powder tableting device 3, and the sample cleaning and crushing device 4. The control device is used to control the opening and closing of each valve 63 and the dust collection host.

[0045] In this embodiment, a pressure detection sensor 7 is provided on the main pipeline 61 of the dust removal system 6; the pressure detection sensor 7 can detect the negative pressure value of the pipeline in a timely manner to determine whether the pipeline is blocked.

[0046] The fully automatic grinding and tableting machine in this embodiment features multiple branch pipes 62, which are connected to the rotary grinding device 2, powder tableting device 3, and sample cleaning and crushing device 4 via independent valves 63. This enables automatic dust collection and cleaning of multiple components of the grinding and tableting machine, eliminating the need for manual cleaning. The operation is simple and convenient. Each branch pipe 62 can be individually controlled, and the dust collection time can be individually controlled according to the cleaning time required for each component of the equipment. This results in higher dust collection efficiency and better dust collection and cleaning effect. The entire process requires no manual intervention, greatly reducing labor intensity and avoiding the problem of cross-contamination of samples due to incomplete cleaning of components in the automatic grinding and tableting machine caused by human negligence.

[0047] like Figure 10 and Figure 11As shown, in this embodiment, the sample cleaning and crushing device 4 includes a sample cleaning mechanism, which includes a slide 41, a first drive assembly 42, an upper suction pipe 43, a lower suction pipe 44, and a first gripper assembly 45; the upper suction pipe 43 and the lower suction pipe 44 are provided with blow nozzles 431; both the upper suction pipe 43 and the lower suction pipe 44 are connected to the branch pipes 62 of the dust removal system 6; the first gripper assembly 45 is used to move the sample between different workstations; the slide 41 has at least one through hole. The first drive assembly 42 is used to drive the slide 41 to move. When it is necessary to clean the sample, the first drive assembly 42 drives the slide 41 to move until the through hole is aligned with the upper suction pipe 43 and the lower suction pipe 44 in the vertical direction. The first gripper assembly 45 clamps the sample between the upper suction pipe 43 and the lower suction pipe 44 or places the sample on the through hole. The blow nozzle 431 blows the upper and lower surfaces of the sample and sucks the dust blown down from the upper and lower surfaces of the sample into the dust removal system 6 through the upper suction pipe 43 and the lower suction pipe 44.

[0048] In this embodiment, the sample cleaning and crushing device 4 also includes a sample detection component, which includes a detection tube 411 and a driving component 412 for driving the detection tube 411 to move up and down. The detection tube 411 is provided with a detection connector 413 connected to a vacuum generator and a negative pressure detection device.

[0049] The slide plate 41 is mounted on the guide rail and slider, and the first drive assembly 42 drives the slide plate 41 to slide. The slide plate 41 has two through holes. When the first drive assembly 42 retracts, the first gripper assembly 45 is horizontally aligned with the through hole on the slide plate 41 away from the first drive assembly 42, and the upper suction pipe 43 and the lower suction pipe 44 are vertically aligned with the through hole on the slide plate 41 away from the first drive assembly 42. The upper end of the upper suction pipe 43 and the lower end of the lower suction pipe 44 are respectively connected to the dust removal system 6. The first gripper assembly 45 will grip the newly made sample and move it until the sample is vertically aligned with the upper suction pipe 43. High-pressure air blows the upper surface of the sample through the blow nozzle 431 on the upper suction pipe 43. The upper suction pipe 43 is connected to negative pressure, and the blown dust is sucked into the dust removal system 6 to complete the cleaning of the upper surface of the newly made sample. The high-pressure air and negative pressure are turned off. The first gripper assembly 45 descends and places the sample onto the through hole on the slide plate 41 away from the first drive assembly 42. High-pressure air blows the lower surface of the sample through the blow nozzle 431 on the lower suction pipe 44. At the same time, the lower suction pipe 44 is connected to negative pressure. The dust that falls after the high-pressure air blows in enters the dust removal system 6 through the negative pressure, completing the cleaning of the lower surface of the newly made sample. The high-pressure air and negative pressure are turned off, the upper suction pipe 43 rises, the first drive assembly 42 extends, and the sample moves to a position vertically aligned with the detection connector 411. The drive assembly 412 descends, causing the detection connector 411 to adhere tightly to the upper surface of the sample. The vacuum generator and negative pressure detection device connected to the detection connector 413 determine whether the sample is cracked. The first drive assembly 42 retracts, and the sample is once again vertically aligned with the upper suction pipe 43. The first gripper assembly 45 moves the sample to the steel ring conveyor 5. The conveyor belt 51 delivers the sample to the side of the control button 54, where it is removed manually or by a robotic arm.

[0050] In this embodiment, the sample cleaning and crushing device 4 further includes a sample crushing component, which includes a second drive component 46, an impact head 47, a first brush component 48, a sample ring fixing component 49, a feeding pipe 410, a second brush component 414, and a brush rotation drive component 415. The feeding pipe 410 is connected to the dust removal system 6. The second drive component 46 is used to drive the impact head 47 to move up and down to break the sample in the sample ring. The first brush component 48 moves up and down with the impact head 47 to clean the inner wall of the sample ring. The brush rotation drive component 415 is used to drive the second brush component 414 to rotate and brush the surface of the sample ring. Furthermore, in a preferred embodiment, the sample ring fixing assembly 49 includes a pressure plate and a dust cover. The second drive assembly 46 drives the pressure plate and dust cover to press against the upper surface of the steel ring, thus fixing the steel ring. The second drive assembly 46 drives the impact head 47 and the first brush assembly 48 through the sample piece. The impact head 47 crushes the sample piece and pushes it into the feed pipe 410. During the descent, the first brush assembly 48 sweeps the inner wall of the steel ring. While the second drive assembly 46 drives the impact head 47, the pressure plate remains pressed against the upper surface of the steel ring. The dust cover prevents dust from being carried out when the first brush assembly 48 rises. After the impact head 47 rises to the top, the second brush assembly 414, driven by the brush rotation drive 415, rotates and passes over the upper surface of the sample ring, sweeping and cleaning the upper surface of the sample ring. Throughout the entire crushing process, the feed pipe 410 is connected to the dust removal system 6 and the dust is removed by negative pressure.

[0051] like Figures 2 to 4 As shown, in this embodiment, the rotary grinding device 2 includes a feeding assembly 21, a dosing tablet assembly 22, a grinding mechanism 23, and a third drive assembly 24. The feeding assembly 21 and the dosing tablet assembly 22 are positioned above the grinding mechanism 23 and communicate with the grinding chamber. The third drive assembly 24 drives the grinding mechanism 23 to rotate to grind the sample. A discharge pipe 25 is provided below the grinding mechanism 23, and a counting component is provided on the dosing tablet assembly 22. Further, in a preferred embodiment, the third drive assembly 24 is connected to the drive shaft of the grinding mechanism 23 via a coupling. The drive shaft is connected to a triangular plate, and the third drive assembly 24 drives the triangular plate to move in the horizontal plane.

[0052] In this embodiment, the pressure cap 231 of the grinding mechanism 23 has an inverted conical through hole 2311 connected to the tablet assembly 22. The inverted conical through hole 2311 is inverted conical. Since the tablet may fall onto the upper surface of the grinding ring instead of into the grinding chamber when it enters the grinding mechanism 23, the tablet may not fall into the grinding chamber due to the centrifugal force causing it to rotate along the tube wall and the upward impact force of the grinding ring when grinding starts. In this embodiment, the tablet inlet is separated from the feed inlet, and the pressure cap 231 is also provided with an inverted conical hole. When the grinding starts, the tablet will be quickly crushed and enter the grinding chamber under the action of the inverted conical surface and the grinding ring, thereby improving the utilization rate of the tablet.

[0053] In this embodiment, the feeding assembly 21 includes a hopper 211 and a first driving cylinder 212. The feeding port of the hopper 211 is provided with a feeding cover 213. The first driving cylinder 212 is used to drive the feeding cover 213 to move to open or close the feeding port. An adjusting block 214 is also provided below the feeding cover 213. There is a gap between the adjusting block 214 and the inner wall of the feeding cover 213. The adjusting block 214 plays a guiding role, guiding the high-pressure airflow to flow along the inner wall of the hopper 211 to sweep away the residual material on the inner wall of the hopper 211.

[0054] like Figures 5 to 9 As shown, in this embodiment, the powder tableting device 3 includes a tableting mechanism, which includes an upper pressure plate 31, a mold assembly 32, a linear module 33, a mold feeding assembly 34, a second gripper assembly 35, and the linear module 33 is used to drive the mold assembly 32 to move in multiple positions; the mold feeding assembly 34 is connected to the discharge pipe 25 of the grinding mechanism 23 and is used to feed the ground material into the mold assembly 32; the second gripper assembly 35 is used to transfer the tableted sample ring to the steel ring conveying device 5.

[0055] In this embodiment, the mold assembly 32 includes a mold driving assembly and a mold body. The mold body includes an outer sleeve 321, an inner sleeve 322, and a top shaft 323. An elastic component 324 is sleeved on the outer wall of the top shaft 323, and a ring mechanism 325 is sleeved on the bottom of the top shaft 323. The mold driving assembly is used to drive the top shaft 323 to move up and down, thereby causing the inner sleeve 322 to slide within the outer sleeve 321. The outer sleeve 321 is disposed on the linear module 33.

[0056] In this embodiment, the mold feeding assembly 34 includes a feeding pipe 341 and a vibrator 342. The vibrator 342 is used to vibrate the feeding pipe 341 to achieve rapid material falling. The discharge end of the feeding pipe 341 is funnel-shaped, and the bottom of the discharge end is provided with multiple obliquely arranged discharge holes 3411.

[0057] In this embodiment, the powder tableting device 3 further includes a mold cleaning assembly, which includes a mold cleaning pipe 312 connected to a branch pipe 62 of the dust removal system 6, a second drive cylinder 313, and a blower pipe 314. The second drive cylinder 313 is used to drive the mold cleaning pipe 312 to move up and down, and the blower pipe 314 blows gas onto the mold assembly 32 to clean the mold assembly 32.

[0058] In this embodiment, the powder tableting device 3 also includes a steel ring storage device for storing and retrieving the cleaned steel rings for subsequent recycling.

[0059] When the ground material needs to enter the mold, the linear module 33 drives the mold assembly 32 to move in multiple positions, and the cylinder assembly 343 drives the feed pipe 341 and the vibrator 342 to move up and down. When the cylinder assembly 343 retracts, it drives the feed pipe 341 to rise. At this time, the mold assembly 32 can move to be coaxial with the feed pipe 341. When the mold assembly 32 is coaxial with the feed pipe 341, the cylinder assembly 343 extends and drives the feed pipe 341 to descend and press against the upper surface of the steel ring. At this time, the material discharged from the discharge pipe 25 can enter the cavity formed by the inner sleeve 322 and the top shaft 323 through the feed pipe 341.

[0060] The upper pressure plate 31 is installed on the adjusting bolt 36. The material enters the cavity formed by the inner sleeve 322 and the top shaft 323. The linear module 33 drives the mold assembly 32 to move and is coaxial with the adjusting bolt 36.

[0061] The mold drive assembly pushes the top shaft 323 upward. During the upward movement of the top shaft 323, the elastic component 324 is compressed. The reaction force of the elastic component 324 pushes the inner sleeve 322 upward. The inner sleeve 322 drives the steel ring to stick to the upper pressure plate 31. At the same time, the powder material is squeezed into the steel ring by the top shaft 323 and pressed into a sheet.

[0062] After tableting is completed, the linear module 33 drives the mold assembly 32 to move to a position perpendicular to the second gripper assembly 35. The second gripper assembly 35 transfers the tableted steel ring to the upper surface of the conveyor belt 51 of the steel ring conveying device 5. Then, the linear module 33 drives the mold assembly 32 to move to the same axis as the mold cleaning pipe 312. The second drive cylinder 313 drives the mold cleaning pipe 312 to descend and approach the upper surface of the inner sleeve 322. The blow pipe 314 introduces high-pressure air to blow away the cavity formed by the inner sleeve 322 and the top shaft 323, so that the cavity is clean. The mold cleaning pipe 312 is connected to the dust removal system 6. The dust carried away by the high-pressure air enters the dust removal system 6 through the mold cleaning pipe 312, realizing the self-cleaning of the mold assembly 32.

[0063] In this embodiment, the powder pressing device 3 also includes a pressing plate cleaning mechanism, which includes a suction duct 37, a rotary drive assembly 38, a motor 39, and a cleaning brush 310. The cleaning brush 310 is connected to the motor 39. The rotary drive assembly 38 is used to drive the motor 39 and the cleaning brush 310 to move between the suction duct 37 and the upper pressing plate 31. The suction duct 37 is connected to a branch pipe 62 of the dust removal system 6. When the rotary drive assembly 38 drives the motor 39 and the cleaning brush 310 to move to the surface of the upper pressing plate 31, the motor 39 drives the cleaning brush 310 to rotate and sweep the surface of the upper pressing plate 31. When the rotary drive assembly 38 drives the motor 39 and the cleaning brush 310 to move to the suction duct 37, the suction duct 37 sucks the residual powder swept off into the dust removal system 6, realizing the self-cleaning of the upper pressing plate 31. The cleaning work of the upper pressing plate 31 can be completed efficiently without disassembling the equipment, which greatly improves the work efficiency.

Furthermore, in a preferred embodiment, the steel ring conveying device 5 also includes an indicator light, which indicates that sample retrieval is required when the indicator light is lit.

[0067] When the sample needs to be sent to the testing equipment after being pressed, the second gripper assembly 35 transfers the pressed sample ring to one end of the conveyor belt 51 (end A in the figure). Driven by the conveyor belt drive mechanism 52, the conveyor belt 51 moves and drives the sample to the other end of the conveyor belt 51 (end B in the figure). When the sample reaches end B of the conveyor belt 51, the detection switch 53 located at end B outputs a signal, and the conveyor belt drive mechanism 52 closes. At this time, the sample can be taken out manually or by a robot.

[0068] When the sample inspection is completed and it needs to be recycled and crushed, the indicator light will illuminate. The sample will be placed at end B of the conveyor belt 51. Press the control button 54, and under the drive of the conveyor belt drive mechanism 52, the conveyor belt 51 will transfer the sample to end A of the conveyor belt 51. After the positioning plate 55 contacts the sample, the detection switch 53 located at end A of the conveyor belt 51 will output a signal, and the conveyor belt drive mechanism 52 will be turned off, completing the sample recycling.
