DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0026] like Figure 1-5As shown, in this embodiment, it includes a frame 1 and a tablet pressing table 2, the tablet pressing table 2 is arranged in the frame 1, and a plurality of tablet pressing grooves 15 are opened on the upper end of the tablet pressing table 2. A pressing head 6 is arranged on the left side of the upper end of the tablet pressing table 2, and a rotating drive component is arranged below the tablet pressing table 2, and the rotating drive component includes a motor 9, a PLC controller 12, a main gear 11, a support shaft 7 and a sub-gear 10. The motor 9 and the PLC controller 12 are fixed to the bottom end of the frame 1, and the main gear 11 is connected to the motor 9. At the power end, one end of the support shaft 7 is fixed to the middle of the lower end of the tablet press table 2, and the other end of the support shaft 7 is rotatably connected to the bottom end of the frame 1. The sub-gear 10 is fixedly sleeved on the outer periphery of the support shaft 7, and the main gear 11 is meshed with the sub-gear 10. A material plate 18 is provided in each of the tablet press grooves 15. A plurality of second proximity switches 16 are connected to the lower end of the tablet press table 2. A material receiving box 8 is provided below the tablet press table 2. A second proximity plate 17 is fixed to the upper end of the outer side of the material receiving box 8. The second proximity switch 16 is connected to the The second approach plate 17 is adapted, and a plurality of installation cavities 19 are opened in the tablet pressing table 2, and the plurality of installation cavities 19 are close to the plurality of tablet pressing grooves 15 one by one, and an electromagnetic adsorption unloading assembly is arranged in each installation cavity 19, and the electromagnetic adsorption unloading assembly comprises a guide rod 20, a slide plate 23, a return spring 22, an electromagnet 21 and a magnetic suction block 24, the guide rod 20 is fixed in the installation cavity 19, the slide plate 23 is slidably sleeved on the outer periphery of the guide rod 20, and the return spring 22 is connected to the side of the slide plate 23. The material plates 18 are slid through the adjacent mounting cavities 19 through the tablet press table 2, and the material plates 18 are fixed to the adjacent slide plates 23. The magnetic blocks 24 are connected to the sides of the slide plates 23. The electromagnets 21 are fixed to the inner walls of the mounting cavities 19, and the electromagnets 21 correspond to the adjacent magnetic blocks 24. The second proximity switches 16 are connected in series with the adjacent electromagnets 21. An electric cylinder 5 is fixed to the left side of the top end of the frame 1, and the pressure head 6 is connected to the power end of the electric cylinder 5.

[0027] When the tablet pressing device is used to process pharmaceutical tablets, on the premise that there are pharmaceuticals in the tablet pressing groove 15, the pharmaceuticals are supported by the material plate 18, and the operation of the electric cylinder 5 drives the pressing head 6 to move downward, and the pressing head 6 presses the pharmaceuticals in the tablet pressing groove 15 into tablets. After the tablets are formed, the contraction of the electric cylinder 5 drives the pressing head 6 to move upward and reset. On the premise that the PLC controller 12 is set to be connected to the motor 9 signal, the motor 9 is controlled by the PLC controller 12 to drive the main gear 11, the sub-gear 10, the support shaft 7 and the tablet pressing table 2 to rotate until the next tablet pressing groove 15 containing pharmaceuticals is located directly below the pressing head 6. At this time, the PLC controller 12 controls the motor 9 to stop working, and the previous tablet pressing groove 15 containing pharmaceuticals is located directly below the pressing head 6. The tablet pressing groove 15 is located directly above the material receiving box 8. At the same time, the second proximity switch 16 next to the tablet pressing groove 15 senses the second proximity plate 17, so the second proximity switch 16 is started and controls the electromagnet 21 to be energized. After the electromagnet 21 is energized, it will absorb the magnetic block 24, and the magnetic block 24 will drive the slide plate 23 to slide along the guide rod 20. At this time, the slide plate 23 will compress the return spring 22, and the slide plate 23 will drive the material plate 18 to move into the installation cavity 19. Since the material plate 18 no longer supports the tablets, the tablets in the tablet pressing groove 15 will automatically fall into the material receiving box 8, thereby completing the automatic unloading and collection operations. Compared with the prior art, it effectively solves the problem of inconvenient tablet collection and makes the unloading and collection of tablets automatic and convenient.

[0028] like Figure 1 , 2 As shown, in this embodiment, the slide plate 23 is slidably sleeved on the outer periphery of the guide rod 20, the return spring 22 is connected between the side of the slide plate 23 and the inner wall of the mounting cavity 19, the material plates 18 are all slidably penetrated into the adjacent mounting cavity 19 through the tablet pressing table 2, and the material plates 18 are all fixed to the adjacent slide plates 23, the magnetic suction block 24 is connected to the side of the slide plate 23, and the electromagnet 21 is fixed to the inner wall of the mounting cavity 19.

[0029] When the tablet pressing table 2 continues to rotate through the rotary drive component and the empty tablet pressing slot 15 is located at the lower end of the electric metering valve 4, the rotary drive component stops working. Since the second proximity switch 16 next to the tablet pressing slot 15 is away from the second proximity plate 17, the second proximity switch 16 is disconnected, so the electromagnet 21 next to the second proximity switch 16 is powered off, and then the rebound force of the return spring 22 drives the slide plate 23 and the material plate 18 to reset, and the material plate 18 is reset and inserted into the tablet pressing slot 15 so that the material can continue to be received through the material plate 18.

[0030] like Figure 1-3As shown, in this embodiment, a storage tank 3 is installed on the right side of the top end of the frame 1, the lower end of the storage tank 3 is connected to an electric metering valve 4, the outer side of the electric metering valve 4 is connected to a first proximity switch 13, and a plurality of first proximity plates 14 are fixed to the upper end of the tableting table 2, the first proximity switch 13 is adapted to the first proximity plate 14, and a plurality of the first proximity plates 14 are close to a plurality of the tableting grooves 15 one by one.

[0031] When the empty tablet pressing groove 15 is located at the lower end of the electric metering valve 4, the first proximity plate 14 next to the tablet pressing groove 15 will be close to the first proximity switch 13. The first proximity switch 13 senses the first proximity plate 14 and automatically starts. Under the premise that the first proximity switch 13 is set to be connected to the signal of the electric metering valve 4, the first proximity switch 13 will control the electric metering valve 4 to open automatically, and then the medicine in the storage box will be automatically discharged through the electric metering valve 4. Finally, the medicine will be automatically added to the empty tablet pressing groove 15, and the electric metering valve 4 will automatically open. Under the premise that a delay module is installed inside, the electric metering valve 4 is started for a period of time and after the filling is completed, the electric metering valve 4 is automatically closed, so it is convenient to automatically add material to the tablet pressing groove 15, effectively solving the trouble of manual control of adding material. In summary, through this reciprocating movement, through the rotation of the tablet pressing table 2, it is convenient to automatically drive the tablet pressing groove 15 to perform tablet pressing processing under the pressure head 6, and the tablets in the tablet pressing groove 15 can be automatically unloaded and collected, and the tablet pressing groove 15 can be automatically and conveniently added, so that the automatic operation effect of the tablet pressing device is better.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
