DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The through holes 51 and the material collection grooves 52 are staggered with each other. A material collection brush 53 is provided above the turntable 5. The material collection brush 53 is fixedly mounted on the lower surface of the driving housing 3, and the bristles of the material collection brush 53 are tightly fitted with the upper surface of the turntable 5.

[0024] A discharge port 14 is provided on one side of the upper surface of the base shell 1, a leakage groove 15 is provided on the side of the upper surface of the base shell 1 away from the discharge port 14, a recovery drawer 12 is slidably provided on the side of the base shell 1 close to the collecting brush 53, and the leakage groove 15 is connected to the interior of the recovery drawer 12.

[0025] When in use, the powder enters the two through holes 51 and is then compressed into tablets. During operation, some powder will fall on the surface of the turntable 5. If it is not cleaned, the next tablet processing will be affected. Therefore, by setting the collection brush 53, when powder falls on the surface of the turntable 5, the rotation of the turntable 5 will cause the collection brush 53 to sweep the powder into the collection trough 52, and then the powder falls into the recovery drawer 12 through the leakage trough 15. The recovery drawer 12 stores the raw materials, realizing automatic cleaning and preventing the accumulation of powder from causing inaccurate processing.

[0026] Two tablet pressing hydraulic rods 6 are embedded in the driving housing 3, and a pressing head 61 is fixedly installed at the telescopic end of the tablet pressing hydraulic rod 6. Two discharging hydraulic rods 7 are embedded in the driving housing 3, and a material return head 71 is fixedly installed at the telescopic end of the discharging hydraulic rod 7. Two transparent pipes 8 are fixedly installed in the driving housing 3. The two tablet pressing hydraulic rods 6, the two discharging hydraulic rods 7, and the two transparent pipes 8 are distributed in an annular shape as a whole. The two tablet pressing hydraulic rods 6, the two discharging hydraulic rods 7, and the two transparent pipes 8 correspond to the six through holes 51 one by one. The length of the material return head 71 is greater than the length of the pressing head 61. The discharging hydraulic rod 7 is located above the discharging port 14, and the diameters of the pressing head 61 and the ejecting head 71 are equal to the diameter of the through hole 51. During processing, the tablet pressing hydraulic rod 6 drives the pressing head 61 to enter the through hole 51 filled with medicine powder, and then presses the medicine powder into tablets. At this time, the turntable 5 rotates, and the through hole 51 filled with tablets is rotated to above the discharging port 14. Then the discharging hydraulic rod 7 works to drive the ejecting head 71 to enter the through hole 51, and pushes the compressed medicine out of the through hole 51 to make it fall into the discharging port 14. The discharging hydraulic rod 7 and the tablet pressing hydraulic rod 6 work at the same time, and the turntable 5 rotates 120° each time.

[0027] The lower surface of the turntable 5 fits tightly with the upper surface of the pressing base 16, and a stepper motor 13 is fixedly installed in the middle position inside the base shell 1, and the stepper motor 13 is used to provide rotation of the turntable 5, and the driving shell 3 can adjust the rotation speed and rotation angle of the turntable 5.

A motion sensor is installed inside the observation shell 2, which is not shown in the figure. The motion sensor can detect the movement state of the turntable 5. When the turntable 5 rotates, the motion sensor sends an electrical signal, and when the turntable 5 stops rotating, the motion sensor stops sending a signal.

[0028] A cabinet door 31 is rotatably installed on one side of the driving shell 3, a first electrically-controlled valve 81 is fixedly installed on the upper end of the transparent pipe 8, a second electrically-controlled valve 82 is fixedly installed on the lower end of the transparent pipe 8, a sliding ring 84 is slidingly sleeved on the outer surface of the first electrically-controlled valve 81, a laser sensor 85 is installed on the sliding ring 84, the sliding ring 84 is located between the first electrically-controlled valve 81 and the second electrically-controlled valve 82, a loading pipe 83 is fixedly installed on the bottom end of the transparent pipe 8, the lower surface of the loading pipe 83 is tightly fitted with the surface of the turntable 5, the outer ring diameter of the loading pipe 83 is smaller than the diameter of the through hole 51, the loading pipe 83, the transparent pipe 8, and the storage bin 4 are connected in sequence, the first electrically-controlled valve 81 and the second electrically-controlled valve 82 can receive signals sent by the motion sensor, and when the turntable 5 is turned, the loading pipe 83 is fixedly installed. When the disk 5 rotates, the second electrically-controlled valve 82 is closed and the first electrically-controlled valve 81 is opened. At this time, the medicine powder falls from the inside of the storage bin 4 into the inside of the transparent pipe 8. When the turntable 5 stops rotating, the second electrically-controlled valve 82 is opened and the first electrically-controlled valve 81 is closed. At this time, the loading pipe 83 is located above two of the through holes 51, and the medicine powder will fall into the inside of the through holes 51. The laser sensor 85 can detect the height of the medicine powder inside the transparent pipe 8. When the medicine powder reaches the height of the laser sensor 85, the laser sensor 85 will send an electrical signal to the first electrically-controlled valve 81 to control the first electrically-controlled valve 81 to close. When in use, the cabinet door 31 can be opened, and then the sliding ring 84 can be slid to adjust the detection height of the laser sensor 85, thereby achieving the purpose of controlling the feed amount.

[0029] By setting up the turntable 5, when in use, the worker only needs to add medicine powder to the inside of the storage bin 4 through the loading port 41, and the tablet pressing hydraulic rod 6 will process the medicine powder into tablets, and realize automatic unloading and automatic loading under the rotation of the turntable 5, without the need for workers to manually unload, and there is no need to load while processing, which can prevent the processed tablets from being contaminated, and also prevent the raw materials from being contaminated. By ensuring that there is sufficient medicine powder in the storage bin 4, automatic processing can be realized, thereby increasing processing efficiency and improving output.
