Description

Technical Field

[0001] The utility model relates to the technical field of tablet press equipment, in particular to a rotary tablet press for producing biological tablets. Background Art

[0002] Tablets are solid preparations in the form of flakes or special-shaped flakes that are formed by evenly mixing drugs and excipients, and the most common biological tablets are various vitamin tablets. In the production of biological tablets, the rotary tablet press is an automatic rotating continuous tablet pressing machine, and is also the basic equipment for processing various granular raw materials into tablets. It is roughly composed of a tablet pressing turntable, a feeding mechanism, and a machine body. After the drug powder enters the turntable, it is tableted, and the formed tablets are discharged from the discharge chute.

[0003] Since the discharge chute of the current rotary tablet press is connected to the turntable and is at a high height from the ground, the way to collect tablets is usually to place buckets, baskets, etc. under the discharge chute port for collection, such as the ZP model and ZPW model rotary tablet press. However, tablets are inherently brittle, and they are affected by gravity acceleration during discharge from the discharge chute. It is difficult for tablets to avoid colliding with the receiving container, which will undoubtedly cause more or less gaps and cracks on the surface of the tablets, thus affecting the quality of the finished product. Even tablets that are slightly damaged and not considered defective will affect their appearance after slight damage. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1 and Figure 2 As shown, the utility model provides a rotary tablet press for producing biological tablets, including a tablet pressing mechanism 1, and a spiral feeding assembly 2 is arranged on the left side wall of the tablet pressing mechanism 1; the tablet pressing mechanism 1 includes a body 11, a controller 12 fixed on the front side of the body 11, and a turntable 13 fixed on the top surface of the body 11; columns are fixed at the four corners of the top surface of the body 11, tempered glass plates are installed between the columns, and a material cup 14 is arranged on the top surface of the column.

[0028] like Figure 3 As shown, the spiral unloading component 2 includes a collecting basket 23 adsorbed and connected to the right side wall of the body 11, a discharge chute 21 connected to the discharge port of the turntable 13, and a spiral slide 22 connected to the end port of the discharge chute 21 away from the turntable 13, and a connecting plate 24 is fixed to the rear side wall of the spiral slide 22, and a bracket is fixed to the side wall of the connecting plate 24 away from the spiral slide 22, and a vibration motor 26 is installed on the bracket; the bottom side wall of the inner cavity and the surrounding side walls of the collecting basket 23 are covered with a layer of velvet lining 29 by adhesive, and two groups of magnet bars 28 are inlaid on the left side of the collecting basket 23.

[0029] In this embodiment, the discharge trough 21 and the spiral chute 22 both have a depth of 3cm-4cm, and the inner cavity side walls of the discharge trough 21 and the spiral chute 22 are electroplated with a film layer, wherein the spiral chute 22 extends downward in a spiral shape, and the end port of the spiral chute 22 away from the discharge trough 21 is located above the top port of the collection basket 23.

[0030] More specifically, the bracket on the side of the connecting plate 24 away from the spiral groove 22 of this embodiment includes: a vibration transmission plate 25 fixedly connected to the rear side wall of the connecting plate 24, a support frame 27 fixed to the left side wall of the vibration transmission plate 25, and the side surface of the support frame 27 away from the vibration transmission plate 25 is fixedly connected to the right side wall of the body 11 by screws; the bottom surface of the vibration motor 26 is fixed with a bottom plate by bolts, and the left side surface of the bottom plate is fixedly connected to the right side surface of the support frame 27, and the right side surface of the bottom plate is fixedly connected to the left side surface of the vibration transmission plate 25.

[0031] More specifically, two grooves are formed on the left side surface of the collection basket 23, and the magnet strips 28 are embedded and fixed in the grooves by adhesive, and the front and rear side surfaces of the collection basket 23 are both connected with handles 210 by screw locking.

[0032] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0033] After the pharmaceutical powder raw material is conveyed from the material cup 14 to the turntable 13 for tableting, the compacted tablets enter the discharge chute 21 as the turntable 13 rotates. Since the axis of the discharge chute 21 has an inclination angle of 30°-40° with the horizontal plane, the tablets slide into the spiral chute 22 under the action of gravity. Since the vibration motor 26 transmits the vibration force to the spiral chute 22 through the bracket, the spiral chute 22 affected by the shaking shakes the internal tablets to move along the spiral direction and finally fall into the collection basket 23. Because the side of the collection basket 23 is provided with a magnet bar 28, when the body 11 is adsorbable, the collection basket 23 can be connected to the side of the body 11 through the magnet bar 28. When the body 11 cannot be adsorbed with the magnet bar 28, it is necessary to install a magnet on the side wall of the body 11 at a position corresponding to the magnet bar 28. The collecting basket 23 is located below the discharge port of the spiral chute 22, and after the tablets are discharged, they fall onto the flannel lining 29 inside the collecting basket 23, achieving a "soft landing" for the tablets.

[0034] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
