[0002] Tablet presses are mainly used for the research of tablet processes in the pharmaceutical industry. Tablet presses are automatic continuous production equipment that presses granular materials into round, special-shaped, and sheet-shaped objects with words, symbols, and graphics with a diameter not greater than 13 mm. When some pharmaceutical tablet presses produce burrs and dust during tablet pressing, a screening machine should be used for dust removal at the same time. When producing chlorine dioxide disinfectant, it is usually produced in the form of AB agents. Agent A is a tablet, and agent B is a water agent. When in use, agent A is dissolved in water, and then agent B is added. Agent A needs to be pressed into shape using a tablet press during production.

[0021] According to the above structure, during use, the cloth-feeding structure 7 adds medicament into the feeding structure 6, the feeding structure 6 sends the medicament into a plurality of pressing grooves 81 on the mold 8, the medicament in the pressing grooves 81 is extruded into a formed shape through the mutual cooperation of the pressing-down structure 3 and the pressing-up structure 4, then a plurality of tablets are ejected from the inside of the pressing grooves 81 by the pressing-down structure 3, when the feeding structure 6 feeds again, the ejected tablets are pushed towards the discharge hopper 9, and feeding is carried out at the same time. A plurality of tablets can be formed in one pressing-down, improving the tablet pressing efficiency.

[0022] As Figure 2 and 3As shown in the figure, the pressing-down structure 3 includes a stabilizing plate 31. A first hydraulic cylinder 32 is arranged in the middle of the stabilizing plate 31. Struts 33 are fixedly connected to the four corners of the stabilizing plate 31. The struts 33 penetrate through the top end of the support frame 2. The top end of the first hydraulic cylinder 32 is fixedly connected to a bottom plate 34. Pressing-down columns 35 are evenly arranged on the top end of the bottom plate 34. A number of pressing-down columns 35 are respectively slidably connected inside a number of pressing grooves 81. The pressing-up structure 4 includes a mounting plate 41. Second hydraulic cylinders 42 are fixedly connected to the four corners of the bottom end of the mounting plate 41. The bottoms of the second hydraulic cylinders 42 are embedded inside the support frame 2. The bottom end of the mounting plate 41 is fixedly connected to a top plate 43. Pressing-up columns 44 are fixedly connected to the bottom end of the top plate 43. A number of pressing-up columns 44 are arranged in one-to-one correspondence with a number of pressing-down columns 35.

[0023] According to the above structure, during tablet pressing, the top of the pressing-down column 35 is inside the pressing groove 81. As the second hydraulic cylinder 42 contracts, the pressing-up column 44 descends, and the bottom end of the pressing-up column 44 extrudes and forms the medicament inside the pressing groove 81.

[0024] As Figure 3 and 4 shown in the figure, the feeding structure 6 includes a mounting frame 61. Lead screws 62 are symmetrically and rotatably connected to the inner side of the mounting frame 61. Reversible motors 63 are symmetrically and fixedly connected to one side of the mounting frame 61. The output shafts of the two reversible motors 63 are respectively fixedly connected to one end of the two lead screws 62. A feeding box 64 is threadedly driven and connected between the two lead screws 62. A pushing plate 65 is fixedly connected to one end of the feeding box 64. A partition plate 66 is fixedly connected inside the feeding box 64. 67 are fixedly connected inside the meshes of the partition plate 66.

[0025] According to the above structure, during feeding, the reversible motor 63 drives the lead screw 62 to rotate, and the lead screw 62 drives the feeding box 64 to move. When the feeding box 64 moves, it can push the ejected tablets towards the discharge hopper 9. When returning, the bottoms of a number of 67 correspond to the tops of a number of pressing grooves 81, so as to add the medicament inside the feeding box 64 into the pressing grooves 81. After the addition is completed, the feeding box 64 returns.

[0026] As Figure 3 and 4 shown in the figure, the material distribution structure 7 includes a support plate 71. Slide rails 73 are fixedly connected to both sides of the support plate 71. A blocking plate 74 is slidably connected between the two slide rails 73. A cylinder 75 is fixedly connected to the bottom end of the blocking plate 74. A spring 76 is fixedly connected inside the cylinder 75. One end of the spring 76 is fixedly connected to one end of the support plate 71. A telescopic rod 77 is arranged inside the spring 76. The two ends of the telescopic rod 77 are respectively fixedly connected to one end of the inner wall of the cylinder 75 and one end of the support plate 71. A leakage groove 72 is arranged on the surface of the support plate 71. A storage box 78 is fixedly connected to the top end of the support plate 71. The bottom end of the storage box 78 corresponds to the leakage groove 72.

[0027] According to the above structure, after the feeding box 64 returns, the top end of the feeding box 64 pushes the blocking plate 74, and the medicament inside the storage box 78 automatically falls into the inside of the feeding box 64 through the leakage groove 72, thereby feeding the feeding box 64. After the feeding is completed, the feeding box 64 moves to the right again. Under the push of the spring 76, the blocking plate 74 moves to the right to block the leakage groove 72. The setting of the telescopic rod 77 can prevent the spring 76 from skewing.

[0028] The working principle of the present utility model is as follows: When in use, the medicament is added into the feeding structure 6 through the feeding structure 7. The feeding structure 6 sends the medicament into several pressing grooves 81 on the mold 8. The pressing structure 3 and the upper pressing structure 4 cooperate with each other to extrude and form the medicament in the pressing grooves 81. Then, the pressing structure 3 pushes several tablets out of the inside of the pressing grooves 81. When the feeding structure 6 feeds again, the pushed-out tablets are pushed towards the discharge hopper 9, and at the same time, feeding is carried out. Several tablets can be formed in one pressing, improving the tableting efficiency. During tableting, the top of the pressing column 35 is inside the pressing groove 81. As the second hydraulic column 42 contracts, the upper pressing column 44 descends, and the bottom end of the upper pressing column 44 extrudes and forms the medicament in the pressing groove 81. During feeding, the forward and reverse motor 63 drives the lead screw 62 to rotate, and the lead screw 62 drives the feeding box 64 to move. When the feeding box 64 moves, it can push the pushed-out tablets towards the discharge hopper 9. When returning, the bottom ends of several

[67] correspond to the top ends of several pressing grooves 81, so as to add the medicament inside the feeding box 64 into the pressing grooves 81. After the addition is completed, the feeding box 64 returns. After the feeding box 64 returns, the top end of the feeding box 64 pushes the blocking plate 74, and the medicament inside the storage box 78 automatically falls into the inside of the feeding box 64 through the leakage groove 72, thereby feeding the feeding box 64. After the feeding is completed, the feeding box 64 moves to the right again. Under the push of the spring 76, the blocking plate 74 moves to the right to block the leakage groove 72. The setting of the telescopic rod 77 can prevent the spring 76 from skewing.

[0029] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
