Description

Technical Field

[0001] The invention relates to the technical field of tablet presses, in particular to a tablet press for producing dispersible tablets. Background Art

[0002] Tablet press is a device used to compress powder or granular materials into tablets. It is widely used in pharmaceutical, food, chemical and other industries. Tablet press can press out round, special-shaped and dispersible tablets with text, symbols and graphics with a diameter not exceeding 13mm. The working process of tablet press includes the steps of sealing the bottom of the middle die hole with the lower punch, filling the powder with the feeder, pressing the powder with the upper punch, lifting the hole with the upper punch, and ejecting the tablet with the lower punch. Dispersible tablets are pressed from powder. When producing dispersible tablets, a tablet press is needed to press the powder into tablets. Therefore, we have launched a tablet press for dispersible tablet production.

[0003] The existing patent (Announcement No.: CN118991122A) discloses a folic acid tablet press, comprising a fixed base, a support platform is fixedly arranged on the top of the fixed base, a workbench is arranged in the support platform, a pressing hole is opened in the workbench, a feeding assembly is arranged on one side of the workbench, a hydraulic rod is arranged on the top of the workbench, a pressing plate is connected to the movable end of the hydraulic rod, and a finished product table is rotatably arranged at the bottom of the workbench; a cleaning assembly is arranged between the hydraulic rod and the pressing plate; the invention arranges a cleaning assembly on the pressing plate, and arranges the finished product table at the bottom of the workbench. After the tablet is successfully pressed, the finished product table is rotated to align the drop port with the pressing hole. At this time, the pressing plate continues to move downward, and the dispersed tablet can be pushed into the falling channel. At the same time, as the pressing plate moves downward, the cleaning roller will also extend into the pressing hole. The driving assembly and the reciprocating motion assembly can drive the cleaning roller to rotate and move up and down to clean the inner wall of the pressing hole. The existing technology has the following problems: after a tablet is pressed once, powder will adhere to the end faces of the upper and lower punch heads of the existing tablet press, resulting in sticking. These powders will be carried into the next tablet press, which may easily cause the problem of mixing of ingredients, thereby affecting the quality of the final tablet. In addition, the sticking phenomenon will increase the breakage rate of the dispersible tablets. Summary of the invention

[0022] In this embodiment, Figure 1 to Figure 2 and Figures 5 to 7As shown, the pressing mechanism 7 includes a reciprocating plate 701 rotatably connected between the front and rear sides of the gantry 2 through a connecting shaft, the middle parts of both sides of the reciprocating plate 701 are rotatably connected with hinged arms 702 through connecting shafts, the bottom ends of the hinged arms 702 are rotatably connected with a pressing plate 703, a mounting groove 704 is provided in the middle of the bottom surface of the reciprocating plate 701, a horizontal shaft 705 is rotatably connected between the two inner walls of the mounting groove 704, an arch 706 is integrally formed on the outer surface of the horizontal shaft 705, a connecting ball 707 is rotatably connected to the middle part of the arch 706, and the connecting ball 707 is movably embedded in the offset The driving shaft 709 is fixedly connected to the middle of the bottom surface of the eccentric wheel 708 and the upper edge of the top surface of the extrusion plate 703. The bending rod 7010 is fixedly connected to the upper edge of the extrusion plate 703. The middle of the bending rod 7010 is integrally formed with a limiting clamp 7011. The limiting clamp 7011 slides and fits on both sides of the limiting strip 7012. The middle of the limiting strip 7012 is provided with a limiting slot, and the bending rod 7010 slides through the middle of the limiting slot. The bending rod 7010 is divided into two groups, the left group of bending rods 7010 and the material taking mechanism 3 and the cleaning mechanism 8. The eccentric wheel 708 is connected to the cleaning mechanism 8, and the bending rod 7010 on the right is only connected to the cleaning mechanism 8. When the driving shaft 709 rotates under the drive of the transmission mechanism 6, the driving shaft 709 will drive the eccentric wheel 708 at the top to rotate eccentrically, and the eccentric wheel 708 will drive the arch 706 to move through the connecting ball 707 at the top.

When the lifting plate 801 moves upward, the inclined groove 802 is used to squeeze the translation rod 803 to move, and the translation rod 803 drives the limiting slider 804 to move synchronously. The limiting slider 804 slides toward the rear side of the base 1 along the horizontal limiting groove 805. During this process, the translation rod 803 will drive the supporting plate 807 to move synchronously. The supporting plate 807 drives the cleaning brush 809 to move through the spring telescopic rod 808 on the top surface. During the movement of the cleaning brush 809, the extrusion plate 703 also moves upward. At this time, the bristle part of the cleaning brush 809 contacts the bottom surface of the extrusion plate 703 to clean the bottom surface of the extrusion plate 703.

When the toggle column 404 enters the toggle groove 406, it will drive the dividing plate 405 to rotate, and each rotation angle is 90°. The dividing plate 405 drives the pressing table 5 to rotate through the support shaft 408, and the output end of the motor 401 is connected to the transmission mechanism 6, thereby driving the drive shaft 709 to rotate through the transmission mechanism 6.

[0027] In this embodiment, Fig.11 As shown, the transmission mechanism 6 includes a pulley 1 601 fixedly connected to the output end of the motor 401, the pulley 1 601 is connected to the pulley 2 602 through a synchronous belt, the middle of the pulley 2 602 is fixedly connected to a main shaft 603, the top of the main shaft 603 is fixedly connected to a pulley 3 604, the pulley 3 604 and the double pulley 605 form a transmission structure through a synchronous belt, the double pulley 605 is connected to the pulley 4 606 through a synchronous belt, the driving shaft 709 rotates and runs through the middle of the installation folding plate 11, and the double pulley 605 is connected to the pulley 4 606 through a synchronous belt.

[0028] In this embodiment, Fig.10 As shown, the feeding mechanism 9 includes a storage box 901 fixedly connected to the middle of the gantry 2, a mounting frame 902 is fixedly connected between the inner walls of the storage box 901, a rotating shaft 903 is provided in the middle of the mounting frame 902 through a bearing interference fit, a crushing rod 904 and a spiral sheet 905 are formed integrally on the outer surface of the rotating shaft 903, the top end of the rotating shaft 903 extends to the outside of the storage box 901 and is connected to a driven gear 906, the driven gear 906 is meshed with a residual gear 907, and a transmission shaft 9 is fixedly connected to the middle of the bottom surface of the residual gear 907. 08; Driven by the transmission mechanism 6, the transmission shaft 908 rotates to drive the residual gear 907 at the top to rotate, and the residual gear 907 can drive the driven gear 906 to rotate with the rotating shaft 903 as the axis. The rotating shaft 903 will drive the spiral piece 905 and the crushing rod 904 to rotate.

That is, when the tablet pressing table 5 rotates, the residual gear 907 does not mesh with the driven gear 906. When the tablet pressing table 5 stops rotating, the residual gear 907 starts to mesh with the driven gear 906, thereby driving the spiral piece 905 to discharge.
