Specific implementation mode

[0024] As Figures 1-6 shown, the present utility model provides a technical solution: a tablet pressing and powder mixing filtering device, including a bottom plate 1, a first cylinder 2 is fixed on the upper surface of the bottom plate 1, the output end of the first cylinder 2 is fixed with a push plate 3, a support column 4 penetrates through the push plate 3 and is slidably connected at the penetration, the support column 4 is fixed on the upper surface of the bottom plate 1, a pressing table 5 is fixed on the upper surface of the support column 4, the push plate 3 penetrates through the bottom surface of the pressing table 5 and is slidably connected at the penetration, a support rod 6 is fixed on the upper surface of the bottom plate 1, a top plate 7 is fixed on the upper surface of the support rod 6, a second cylinder 8 is fixed on the bottom surface of the top plate 7, the output end of the second cylinder 8 is fixed with a piston rod 9, a pressing plate 10 is fixed on the bottom surface of the piston rod 9, a filtering mechanism 11 is arranged on the side wall of the support rod 6, and a collection mechanism 12 is arranged on the filtering mechanism 11.

[0025] The above-mentioned filtering mechanism 11 includes a first hinge block 111, a material storage box 112, a material discharge hole 113, a filter plate 114, a sliding groove 115, a sliding rod 116, a scraping plate 117, a first rotating block 118, a second rotating block 119 and a spring 1110. The first hinge block 111 is fixed on the side wall of the support rod 6, and the side wall of the material storage box 112 is fixedly connected to the first hinge block 111. By rotating the material storage box 112, the material storage box 112 rotates around the central axis of the first hinge block 111. A material discharge hole 113 is opened on the bottom surface of the material storage box 112. When the material storage box 112 moves above the pressing table 5, the material discharge hole 113 coincides with each pressing hole on the pressing table 5. A filter plate 114 is fixed in the middle of the material storage box 112. A sliding groove 115 is opened on the upper surface of the material storage box 112, and a sliding rod 116 slides on the inner wall of the sliding groove 115. The rotation of the material storage box 112 drives the sliding rod 116 to move. A scraping plate 117 is fixed to the bottom surface of the sliding rod 116. The sliding rod 116 slides along the sliding groove 115 under the tension of the spring 1110, driving the scraping plate 117 to move on the filter plate 114. A first rotating block 118 is rotated at the upper end of the sliding rod 116, and a second rotating block 119 is rotated at the upper end of the first hinge block 111. The side wall of the second rotating block 119 is fixedly connected to one end of the spring 1110, and the other end of the spring 1110 is fixedly connected to the side wall of the first rotating block 118. The movement of the sliding rod 116 drives the first rotating block 118 to move, and the movement of the first rotating block 118 drives the spring 1110 to move and simultaneously stretches the spring 1110. This filtering mechanism 11 can filter the powder before tablet pressing, avoiding some powder agglomeration and adhesion after powder mixing, which may affect tablet pressing, and at the same time avoiding blockage of the powder on the filter plate 114.

[0026] The above-mentioned collection mechanism 12 includes a second hinge block 121, a third hinge block 122, a limiting block 123, a collection box 124 and a screw 125. The second hinge block 121 is fixed on the side wall of the material storage box 112. The second hinge block 121 is hinged to the third hinge block 122. A limiting block 123 slides on the side wall of the third hinge block 122. A collection box 124 is fixed to the side of the limiting block 123 away from the third hinge block 122. By rotating the material storage box 112, when the material storage box 112 moves onto the pressing table 5, the collection box 124 is ejected by the pressing table 5. A screw 125 passes through the limiting block 123 and is threadedly connected at the passing position. By rotating the screw 125, the screw 125 no longer passes through the limiting block 123, and the collection box 124 can be slid down and taken out. The screw 125 passes through the third hinge block 122 and is rotatably connected at the passing position. This collection mechanism 12 can collect the filtered powder during the primary filtering process, avoiding waste, and then performing secondary filtering, making the powder more complete and making tablet pressing more convenient.

[0027] Working principle: Pour the crushed powder into the material storage box 112, rotate the material storage box 112, and the material storage box 112 rotates around the central axis of the first hinge block 111. The rotation of the material storage box 112 drives the sliding rod 116 to move, the movement of the sliding rod 116 drives the first rotating block 118 to move, the movement of the first rotating block 118 drives the spring 1110 to move, and at the same time stretches the spring 1110. The sliding rod 116 slides along the chute 115 under the pulling force of the spring 1110, driving the scraper 117 to move on the filter plate 114 to disperse the powder on the filter plate 114.

[0028] Rotate the material storage box 112, and the material storage box 112 moves to the pressing table 5. The collection box 124 is ejected by the pressing table 5. Rotate the screw 125 so that the screw 125 no longer penetrates the limiting block 123, slide the collection box 124 downward to take it out, pour the powder in the collection box 124 into the material storage box 112 to filter the powder for the second time, and directly fall into each pressing hole of the pressing table 5 after filtration. Move the material storage box 112 away and start the cylinder to press the tablets.

[0029] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
