[0028] The automatic cleaning system for the grinder and press in this embodiment is equipped with multiple branch pipes 3, and the branch pipes 3 are connected with the sample surface cleaning component 5, the sample crushing cleaning component 6, the upper mold sweeping brush cleaning component 7, the grinding component cleaning component 8, and the tablet pressing mold cleaning component 9 through independent dust suction valves 4, thereby realizing automatic dust suction cleaning of multiple parts of the grinder and press, without manual cleaning, and the operation process is simple and convenient. Each branch pipe 3 can be switched on and off individually, and the dust suction time can be individually controlled according to the cleaning time required for each part of the equipment. The dust suction efficiency is higher and the dust suction cleaning effect is better, which can avoid the problem of unclean cleaning of parts in the grinder and press due to human negligence, resulting in cross contamination of samples.

[0029] In this embodiment, the sample surface cleaning component 5 includes a sample upper surface cleaning component 51, a sample lower surface cleaning component 52 and a sample clamp 53. The sample upper surface cleaning component 51 includes a dust hood 54, and the sample lower surface cleaning component 52 includes a dust pipe 55. The dust hood 54 and the dust pipe 55 are connected to the branch pipeline 3. When the sample is pressed, the sample clamping claw 53 clamps the sample for transfer. When the sample is transferred to the bottom of the dust cover 54 of the sample upper surface cleaning component 51, the control device controls the dust valve 4 connected to the sample upper surface cleaning component 51 to open, the dust host 1 starts, and starts to vacuum the upper surface of the sample to clean the upper surface of the sample; after the dust is finished, the dust host 1 stops and the dust valve 4 is closed, and the cleaning of the upper surface of the sample is completed; after the upper surface of the sample is cleaned, the sample clamping claw 53 clamps the sample and puts it into the dust pipe 55 of the sample lower surface cleaning component 52, and starts to clean the bottom of the sample. At this time, the control device controls the dust valve 4 connected to the dust pipe 55 to open, the dust host 1 starts, and vacuums the bottom of the sample; after the dust is finished, the dust host 1 stops and the dust valve 4 is closed, and the cleaning of the bottom of the sample is completed.

[0030] In this embodiment, the sample fragment crushing and cleaning assembly 6 includes a shell 61, in which are arranged a fragmentation mechanism 62, a cylinder brush assembly 63, a fixing mechanism 64 for fixing the sample ring, a feed pipe 65 and a collecting bucket 66 connected to the bottom of the shell 61, and the collecting bucket 66 is connected to the branch pipeline 3. The fragmentation mechanism 62 includes a fragmentation drive assembly 621 and a fragmentation rod 622. The fragmentation drive assembly 621 is used to drive the fragmentation rod 622 to move up and down to break the sample in the sample ring. The cylinder brush assembly 63 is sleeved on the fragmentation rod 622, and the cylinder brush assembly 63 moves up and down with the fragmentation rod 622 to clean the inner wall of the sample ring.

[0031] When it is necessary to crush and clean the sample pieces, the sample ring is fixed by the fixing mechanism 64, and the fragment driving assembly 621 begins to descend. During the descent of the fragment driving assembly 621, the fragment rod 622 breaks the sample pieces in the sample ring, and the broken sample pieces fall into the collecting bucket 66 below along the discharge pipe 65. The collecting bucket 66 is connected to the branch pipeline 3. When the sample pieces begin to break, the vacuum cleaner host 1 also starts to start, and a certain suction force is also generated at the discharge pipe 65, which can suck away the dust generated by the fragments, and the large pieces of sample pieces after the fragments fall into the collecting bucket 66. The barrel brush assembly 63 mounted on the fragment rod 622 sweeps the inner wall of the sample ring as the fragment rod 622 moves downward. The powder swept off the sample ring is sucked away by the vacuum cleaner host 1 at the same time, and the powder adhered to the top of the barrel brush assembly 63 is also sucked away by the vacuum cleaner host 1, so that the barrel brush assembly 63 always maintains a good cleaning ability.

[0032] In this embodiment, the sample crushing and cleaning assembly 6 further includes a cleaning rotary drive assembly 67 and a sweeping brush assembly 68. The cleaning rotary drive assembly 67 is used to drive the sweeping brush assembly 68 to move to clean the outer wall of the sample ring.

[0033] When the fragmentation driving assembly 621 descends to the lower position, the fragmentation driving assembly 621 starts to move upward with the fragmentation rod 622. At the same time, the barrel brush assembly 63 mounted on the fragmentation rod 622 sweeps the inner wall of the sample ring again. When the fragmentation driving assembly 621 rises to the upper position, the fixing mechanism 64 moves upward to leave the sample ring. Subsequently, the cleaning rotary driving assembly 67 starts to drive the sweeping brush assembly 68 to move and sweep the surface of the sample ring. When the surface of the sample ring is swept, the cleaning rotary driving assembly 67 moves the sweeping brush assembly 68 back to the initial position. During the process of fragmentation and sweeping the surface of the sample ring, the vacuum cleaner main unit 1 continues to remain in the turned-on state. When the cleaning rotary driving assembly 67 sweeps with the sweeping brush assembly 68, the sweeping brush assembly 68 is also vacuumed and cleaned, so that the sweeping brush assembly 68 continues to maintain a good cleaning ability.

[0034] In this embodiment, the upper mold sweeping brush cleaning assembly 7 includes a rotary drive mechanism 71, a cleaning block 72, a rotary drive assembly 73, a mounting plate 74 and an air suction assembly 75.

[0035] When the sample is pressed, the rotary drive mechanism 71 drives the cleaning block 72 to be pressed under the pressing mold. When the rotary drive mechanism 71 rotates into place, the rotary drive assembly 73 starts to rotate and drives the cleaning block 72 above to rotate. Under the action of the cleaning block 72, the pressing mold is cleaned. When the pressing mold is cleaned, the rotary drive mechanism 71 drives the cleaning block 72 back to the initial position, and the dust adhering to the cleaning block 72 is sucked away by the suction assembly 75. While the suction assembly 75 sucks the dust, the rotary drive assembly 73 drives the cleaning block 72 to rotate, thereby ensuring that every position of the cleaning block 72 can be cleaned. By setting the suction assembly 75 to achieve self-cleaning of the cleaning block 72, the cleaning block 72 can maintain a good cleaning ability, avoid secondary contamination of the pressing mold after multiple cleanings, and effectively improve the accuracy of detection.

[0036] In this embodiment, the upper mold sweeping brush cleaning assembly 7 also includes a purge assembly 76, which is arranged below the cleaning block 72 and is used to purge the dust adhering to the cleaning block 72. While the suction assembly 75 absorbs the dust, the purge assembly 76 installed below the cleaning block 72 blows air at the same time, and the air outlet of the purge assembly 76 is just facing the bottom of the cleaning block 72. The purge assembly 76 can be used to blow away the dust adhering to the cleaning block 72. Since the cleaning block 72 is in the self-cleaning process, the rotary drive assembly 73 drives the cleaning block 72 to rotate, so that all positions of the cleaning block 72 can be purged, so that the cleaning block 72 can maintain a good cleaning ability and avoid secondary contamination of the pressing mold.

[0037] In this embodiment, the grinding part cleaning assembly 8 includes a discharge pipe 81, a waste pipe 82 and a lifting drive mechanism 83. One end of the discharge pipe 81 is connected to the inner cavity of the grinding part, and one end of the waste pipe 82 is connected to the branch pipeline 3. The lifting drive mechanism 83 is used to drive the waste pipe 82 to move up and down, so that the other end of the waste pipe 82 can be connected or separated from the other end of the discharge pipe 81.

[0038] After the grinding parts have finished grinding, the grinding box inside the grinding parts needs to be cleaned to prevent cross contamination during the next sample preparation. When cleaning is required, the waste pipe 82 moves upward under the action of the lifting drive mechanism 83 and docks with the discharge pipe 81. When the docking is completed, the control device controls the dust suction valve 4 connected to the grinding part cleaning assembly 8 to open, and the dust suction main unit 1 starts to start vacuuming and cleaning the inside of the grinding box. After the vacuuming and cleaning is completed, the lifting drive mechanism 83 descends, the dust suction valve 4 is closed, and the dust suction main unit 1 stops, thereby completing the cleaning of the grinding parts.

[0039] In this embodiment, the tablet pressing mold cleaning assembly 9 includes a moving assembly 91 for driving the tablet pressing mold 95 to move, a mold dust hood 92 and a lifting drive assembly 93. The mold dust hood 92 is connected to the branch pipeline 3, and the lifting drive assembly 93 is used to drive the mold dust hood 92 to rise and fall.

[0040] After the sample is pressed, the residual sample inside the tablet mold 95 also needs to be cleaned. The moving component 91 transfers the tablet mold 95 to the sample transfer position. At this time, the sample clamp 53 transfers the sample above the tablet mold 95, and then the moving component 91 moves the tablet mold 95 to the tablet mold cleaning component 9; after it is in place, the lifting drive component 93 moves downward, and the mold dust cover 92 is connected to the branch pipeline 3 through the dust valve 4. When the lifting drive component 93 is lowered into place, the position sensing switch senses, the control device controls the dust valve 4 to open, and then the dust host 1 is started, and the mold dust cover 92 starts to vacuum and clean the inside of the tablet mold 95.

[0041] In this embodiment, the tableting mold cleaning assembly 9 further includes an air blowing pipe 94, which is used to blow air into the mold dust cover 92. The air blowing pipe 94 is installed on the side of the mold dust cover 92. While vacuuming, the air blowing pipe 94 also blows air, and the tableting mold 95 is cleaned by blowing and vacuuming at the same time. After the cleaning is completed, the lifting drive assembly 93 rises, and after rising to the right position, the position sensing switch detects a signal, the vacuuming main unit 1 stops, and the vacuuming valve 4 is closed, and the cleaning of the tableting mold 95 is completed.

[0042] In this embodiment, a negative pressure detection component 10 (such as a negative pressure detection sensor) is also provided on the main pipeline 2. The negative pressure detection component 10 can provide real-time feedback on the negative pressure value of each branch pipeline 3, thereby confirming the vacuum cleaning effect and preventing the equipment from being in an abnormal state, resulting in poor vacuum cleaning effect.
