[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0026] like Figure 1-7As shown, a propellant tablet pressing machine mainly consists of a base plate 1, columns 2, a top plate 3, side columns 5, a pressing and ejecting assembly, a spreading assembly, a sweeping assembly, a vertical moving assembly, and a pressing upper cooperating assembly. The top plate 3 is mounted on the base plate 1 via the columns 2. Side columns 5 are located on both the left and right sides of the base plate 1. The base plate 1, columns 2, top plate 3, and side columns 5 form the supporting frame of the entire pressing machine. The vertical moving assembly mainly carries the spreading and sweeping assembly, moving them up and down along with the pressing and ejecting assembly. The pressing and ejecting assembly, in conjunction with the pressing upper cooperating assembly, presses the propellant tablets. Simultaneously, the pressing and ejecting assembly ejects the pressed tablets. In this embodiment, four columns are arranged in a rectangular pattern, and two side columns are spaced apart on each side.

[0027] The propellant ejection assembly is located above the base plate 1, and the propellant upper fitting assembly is located below the top plate 3. Each side column 5 is equipped with a vertically moving assembly that moves up and down together with the propellant lower fitting assembly. The left vertically moving assembly has a propellant application assembly, and the right vertically moving assembly has a propellant sweeping assembly. The propellant ejection assembly includes a press 4, a propellant lower fitting assembly, and an ejection assembly. The propellant lower fitting assembly moves upward under the action of the press 4, thus cooperating with the propellant upper fitting assembly to compress the propellant tablets. The ejection assembly ejects the compressed tablets from the propellant lower fitting assembly under the action of the press 4.

[0028] During operation, the drug application component works first to apply the drug, then the drug sweeping component works to sweep off excess drug powder, then the lower drug pressing component moves upward under the action of the press, and works with the upper drug pressing component to compress the propellant tablet. After compression is completed, the press moves downward, and at the same time the ejector component ejects the compressed tablet from the lower drug pressing component. Finally, the drug sweeping component works to sweep the compressed tablet into the tableting box.

[0029] The specific structure of the propellant loading assembly includes a metering plate 6 and a pusher plate 7. The metering plate 6 has several metering holes 6a that are vertically connected and accommodate the propellant. A press moving plate 9 is connected to the bottom of the metering plate 6 via a connecting column 8. The output end of the press 4 is fixed below the press moving plate 9, meaning that when the press is working, it can move along with the metering plate and the press moving plate. To ensure the accuracy of the press moving plate's vertical movement, a propellant guide column 10 is vertically installed on the press 4 to guide the press moving plate 9 during its vertical movement. The upper end of the propellant guide column 10 is slidably connected to the press moving plate 9.

[0030] To achieve the compression of the powder in the metering orifice, a lower push plate 7 is positioned between the press moving plate 9 and the metering plate 6, with a sliding connection between the connecting column 8 and the lower push plate 7. A lower pressing column 7a is also provided on the lower push plate 7 corresponding to each metering orifice 6a. To prevent powder spillage, the distance between the metering plate 6 and the lower push plate 7 is always less than the height of the lower pressing column 7a. Furthermore, to facilitate the ejection of the compressed tablets, the depth of the metering orifice 6a is no greater than the height of the lower pressing column 7a.

[0031] The ejector assembly includes a vertically extending top column 11. The lower end of the top column 11 is fixed to the press 4, and the upper end passes through the press moving plate 9 and is located below the lower push plate 7. The top column limits the downward movement of the lower push plate. A push plate 12 is spaced below the lower push plate 7 and is slidably connected to the top column 11. A connecting plate 15 is provided between the lower push plate 7 and the push plate 12, and both the lower push plate 7 and the push plate 12 are fixedly mounted on the connecting plate 15. This connecting plate connects the lower push plate and the push plate into a single unit, ensuring that the lower push plate and the push plate move in the same direction.

[0032] The specific structure of the pressing assembly includes an upper pressure plate 41 located below the top plate 3 via a front-rear moving assembly. A pressing column 41a is provided on the upper pressure plate 41 corresponding to each metering hole 6a. The front-rear moving assembly specifically includes a front-rear moving cylinder 42 and an I-shaped front-rear moving plate 43. The upper pressure plate 41 is fixedly located below the front-rear moving plate 43. The front-rear moving cylinder 42 is located on the rear side of the top plate 3 via a front-rear cylinder seat 44, and its output end passes through the front-rear cylinder seat 44 and is located on the rear side of the front-rear moving plate 43. To facilitate the front-rear moving plate's movement under the action of the front-rear moving cylinder, side baffles 45 are also provided below the top plate 3 on the left and right sides of the front-rear moving plate 43. A lower baffle 46 is provided below the side baffles 45 to prevent the front-rear moving plate 43 from falling, and the lower baffle 46 forms a sliding groove between itself and the top plate 3 for the upper end of the front-rear moving plate 43 to move back and forth.

[0033] To ensure that the upper pressure column can accurately extend into the metering hole when the metering plate moves upward, a positioning column 13 is provided on the push plate 12, and the upper end of the positioning column 13 passes through the lower push plate 7 and the metering plate 6 sequentially. At the same time, a positioning hole 41b is provided on the upper pressure plate 41 for the positioning column 13 to be inserted. Furthermore, a front baffle 47 is provided in front of the side baffle 45, and a positioning detection sensor 48 is provided on the front baffle 47 to detect the positioning of the front and rear moving plates 43. Only after the positioning detection sensor determines that the front and rear moving plates have moved forward into position can the upper pressure column accurately extend into the metering hole.

[0034] Based on the above structure, during propellant application, there is a certain distance between the metering plate and the upper push plate, and the upper end of the top column just touches the bottom surface of the upper push plate. There is also a certain distance between the press moving plate and the push plate, with the upper pressure plate located at the rear. The propellant ejection process is as follows: After the propellant is filled into the metering hole, the press operates, driving the press moving plate and the metering plate upwards together. At this time, the upper push plate and the push plate do not move, while the distance between the upper push plate and the metering plate increases, and the lower pressure column does not exit the metering hole. When the press moving plate contacts the push plate, under the continued action of the press, it will drive the press moving plate, the push plate, the upper push plate, and the metering plate upwards together. During the upward movement of the press, the forward and backward moving cylinders operate, pushing the upper pressure plate forward until the positioning sensor detects that the upper pressure plate has moved into position, at which point the forward and backward moving cylinders stop operating. As the press moves upward, the positioning pin is inserted into the positioning hole, and then the upper pressure pin extends into the metering hole. The propellant in the metering hole is compressed into tablets by the cooperation of the upper and lower pressure pins. After the tablets are successfully compressed, the press moves downward, simultaneously moving the press moving plate and the metering plate downward. At the same time, the upper push plate and the push plate also move downward under gravity until the upper push plate is stopped by the top pin. The upper push plate and the push plate stop moving, but the press continues to move downward. At this time, the distance between the metering plate and the upper push plate gradually decreases until the metering plate can no longer move downward. At this point, the lower pressure pin just removes the tablets from the metering hole. Then, the sweeping assembly works to sweep away the tablets. After the propellant is swept away, the press moves upward, causing the press moving plate and the metering plate to return to the spreading state. During the sweeping process, the upper pressure plate also returns to the spreading state.

[0035] To facilitate the return of the metering plate to the application state, a spring 14 is provided between the push plate 12 and the metering plate 6, which is fitted onto the connecting post 8. The connecting plate 15 is provided with upper and lower through holes for the spring 14, the positioning post 13, and the top post 11 to pass through.

[0036] The specific structure of the vertical moving component includes a vertical moving plate 16, a vertical moving guide rail 17 on the side column 5, and two vertical moving sliders 18 that can slide vertically on each vertical moving guide rail 17 on the vertical moving plate 16 at intervals. The left and right sides of the press moving plate 9 are connected to the corresponding vertical moving plate 16 through a dosage adjustment component.

[0037] The dosage adjustment assembly includes a U-shaped adjustment seat 19 mounted on the upper and lower movable plate 16 and facing the press movable plate 9. Adjusting bolts 20 are provided at both the upper and lower ends of the adjustment seat 19, and the adjusting bolts 20 pass through the adjustment seat 19 and abut against the press movable plate 9. Adjusting the relative position of the upper and lower adjusting bolts 20 adjusts the height between the press movable plate 9 and the lower push plate 7 during application of the propellant, thereby adjusting the distance between the lower push plate 7 and the metering plate 6, and thus changing the capacity of the metering orifice 6a to hold the propellant.

[0038] The specific structure of the application assembly includes an application base plate 21 mounted on the left-side vertically movable assembly. An application box moving cylinder 22 extends horizontally above the application base plate 21, and an application box 23, penetrating vertically, is located at the output end of the application box moving cylinder 22. To prevent leakage of the propellant from the application box when no application is being performed, a baffle plate 27 is located below the application box 23. A baffle plate cylinder 24 is located on the bottom surface of the application base plate 21, and the baffle plate 27 can press against the upper left side of the metering plate 6 under the action of the baffle plate cylinder 24. The baffle plate 27 is slidably mounted on the application base plate 21 via the left-right movable assembly.

[0039] The left and right moving component includes two left and right moving slide rails 26 spaced apart below the medicine application base plate 21, and a left and right slider 28 that can move left and right on the left and right moving slide rails 26 is provided above the medicine baffle plate 27 at the position corresponding to the position of the left and right moving slide rails 26.

[0040] The application process is as follows: When applying the medicine, the baffle cylinder works so that the baffle can rest against the left side of the metering plate. Then, the medicine box moving cylinder works so that the medicine box moves back and forth on the left and right above the metering plate until the application is completed.

[0041] The sweeping assembly includes a sweeping base plate 29 and a sweeping brush 30. The sweeping base plate 29 is mounted on the right-side vertical movement assembly. The sweeping brush 30 is mounted on the sweeping base plate 29 via a position adjustment assembly, which enables the sweeping brush 30 to move vertically and horizontally. The position adjustment assembly includes a vertical position adjustment assembly and a horizontal position adjustment assembly. The horizontal position adjustment assembly is mounted on the sweeping base plate 29, and the vertical position adjustment assembly is mounted on top of the horizontal position adjustment assembly.

[0042] The left-right position adjustment assembly includes a left-right adjustment cylinder 34, which is mounted on the sweeping base plate 29 via a left-right adjustment cylinder seat 35. The output end of the left-right adjustment cylinder 34 passes to the left through the left-right adjustment cylinder seat 35 and is positioned at a left-right adjustment plate 36. To facilitate the left-right movement of the sweeping brush, left-right guide posts 33 are also provided. The left end of the left-right guide posts 33 is positioned on the right side of the left-right adjustment plate 36, and the right end of the left-right guide posts 33 passes through a guide seat 37 mounted on the sweeping base plate 29. The up-down position adjustment assembly includes an up-down adjustment cylinder 38, which is mounted on the left-right adjustment plate 36. The output end of the up-down adjustment cylinder 38 passes downward through the left-right adjustment plate 36 and is positioned at an up-down adjustment plate 39. To facilitate the up-down movement of the sweeping brush, an up-down guide post 40 is provided between the up-down adjustment plate 39 and the left-right adjustment plate 36.

[0043] To facilitate the collection of swept-off powder, a powder box 25 is provided below the baffle plate 27, resting against the lower left side of the metering plate 6. The powder box 25 is mounted on the left-side vertical moving assembly via the powder plate 49. To facilitate the collection of tablets, a tablet box 31 is provided below the sweeping brush 30, resting against the lower right side of the metering plate 6. The tablet box 31 is mounted on the right-side vertical moving assembly via the tablet plate 32. To collect both powder and tablets, two horizontally extending baffles are provided at intervals on the metering plate, positioned on both sides of all metering holes.

[0044] The powder sweeping process includes powder sweeping and tablet sweeping. Powder sweeping occurs after the powder application is complete, and is detailed as follows: After application, the up-and-down adjusting cylinder lowers the sweeping brush to the top of the measuring plate. Then, the left-and-right adjusting cylinder sweeps the powder from the measuring plate into the powder box on the left. Next, the up-and-down adjusting cylinder moves the sweeping brush away from the measuring plate. Finally, the left-and-right adjusting cylinder returns the sweeping brush to its original position. When multiple powder sweeps are required, each sweep is performed from right to left. For tablet sweeping, after the tablet is ejected, the left-and-right adjusting cylinder moves the sweeping brush to the left side of the measuring plate. Then, the up-and-down adjusting cylinder lowers the brush to the top of the measuring plate. The left-and-right adjusting cylinder then moves the brush to the right, sweeping the tablet into the tablet box. Finally, the up-and-down adjusting cylinder returns the brush to its original position.
