Description

Technical Field

[0001] This utility model relates to the field of gas-producing drug production technology, specifically a waste rejection mechanism for a high-speed tablet press. Background Technology

[0002] A tablet press is a machine that compresses dry granular or powdery materials into tablets using a mold. It is mainly used in the pharmaceutical industry to prepare various solid oral medications, such as antibiotics, cough suppressants, and cold medicines.

[0003] Tableting involves filling a mold with mixed powder and pressing it under a hydraulic press (pressure 50-100MPa) to form tablets with a diameter of 5-10mm and a thickness of 2-5mm.

[0004] Gas-producing drugs are a class of medications that generate gas in the digestive tract to aid in medical examinations or treat bloating. They mainly produce gases such as carbon dioxide through chemical or physical reactions, helping to expand the gastrointestinal tract or promote gas expulsion. They should be used under the guidance of a doctor to avoid self-abuse.

[0005] The propellant in airbags mainly contains substances such as NaN3, Fe2O3, KCIO4, and NaHCO3. When a car collides, the propellant produces a large amount of gas, causing the airbag to inflate rapidly and thus providing protection.

[0006] In addition, tablet presses are also used in the food industry, such as in the production of compressed foods and chewing gum. However, when tablet presses are producing tablets, they also produce defective products, such as broken or cracked tablets. In order not to affect the yield of finished tablets, a rejection mechanism is needed to remove the defective products. Because the degree of drug breakage varies, it is necessary to classify and collect broken products of different sizes. Traditional rejection mechanisms do not have this function. In order to improve this situation, a rejection mechanism for a high-speed tablet press is proposed.

[0007] For example, the rejection mechanism of a high-speed tablet press disclosed in the authorization announcement number CN221983169U includes a support platform, an identification box fixedly connected to the upper end of the support platform, a feeding cylinder fixedly connected to one side of the inner wall of the identification box, a tablet body being disposed inside the feeding cylinder, a conveying disc being rotatably connected to the inner bottom of the identification box, a plurality of grooves for engaging the tablet body being evenly spaced on the outer wall of the conveying disc, and three feeding holes for discharging the tablet body being evenly spaced at the lower end of the identification box, wherein two of the feeding holes are provided with waste diameter adjustment components, which are used to adjust the diameter of the feeding holes;

[0008] Although it solves the problem that traditional waste removal mechanisms require replacing waste removal components when removing pharmaceutical waste of different sizes according to usage needs, which leads to increased operational complexity and cost and reduces the working efficiency of high-speed tablet presses;

[0009] However, the existing waste removal mechanism does not solve the problems that make it difficult to remove broken tablets of different sizes through multi-stage screening, classify and collect broken tablets, or flexibly adjust the blowing and cleaning position, thus affecting the convenience of tablet waste removal and the effectiveness of cleaning adhering dust. Utility Model Content

[0010] The purpose of this invention is to provide a waste removal mechanism for a high-speed tablet press, so as to solve the problems mentioned in the background art, which are not convenient for multi-stage screening to remove broken tablets of different sizes, are not conducive to the classification and collection of broken tablets and the flexible adjustment of the cleaning position, and affect the convenience of tablet waste removal and the effectiveness of blowing to clean the adhering dust.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a waste rejection mechanism for a high-speed tablet press, comprising a collection box and a waste rejection frame. The top of the collection box is provided with a waste rejection frame, and a waste rejection barrel is provided inside the waste rejection frame, with the waste rejection barrel being movably connected to the waste rejection frame. A transfer frame is provided on the outer wall of the waste rejection frame, and a transfer sleeve is provided at the center of the transfer frame. A drive seat is provided on the side of the transfer frame near the waste rejection barrel. A drive motor is provided on the outer wall of the waste rejection frame on one side of the transfer frame. A drive shaft is provided at the output end of the drive motor. A gear is fitted on the surface of the drive shaft, and a gear ring is fitted on the surface of the waste rejection barrel on one side of the gear, with the gear ring meshing with the gear.

[0012] Preferably, the surface of the waste removal bin is provided with multiple sets of large mesh holes at equal intervals, and the surface of the waste removal bin on one side of the large mesh holes is provided with multiple sets of medium mesh holes at equal intervals.

[0013] Preferably, the surface of the waste removal bin on one side of the central mesh is provided with multiple sets of small mesh holes at equal intervals, and the inner wall of the waste removal bin is provided with multiple sets of guide strips at equal intervals.

[0014] Preferably, the collection box below the waste bin is equipped with three sets of collection bins, and the three sets of collection bins correspond one-to-one with the large mesh, medium mesh, and small mesh, respectively.

[0015] Preferably, each of the collection bins has a pull-out box that can be slidably installed inside, and the pull-out box can be pulled out from inside the collection bin.

[0016] Preferably, a stepper motor is provided on the side wall of the drive base, and a worm gear is installed at the output end of the stepper motor, and the worm gear is movably connected to the drive base.

[0017] Preferably, a curved air pipe is movably installed inside the drive seat on one side of the worm gear, and the curved air pipe extends into the interior of the waste removal bin, and the curved air pipe is movably connected to the waste removal bin.

[0018] Preferably, a worm wheel is fitted on the surface of the curved air pipe on one side of the worm, and the worm and the worm wheel mesh with each other, and a nozzle is provided at the port of the curved air pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the waste removal mechanism not only realizes multi-stage screening to remove broken tablets of different sizes, facilitating the classification and collection of broken tablets and the flexible adjustment of the cleaning position, but also improves the convenience of tablet waste removal and the effectiveness of blowing away adhering dust.

[0020] (1) Pour the tablets mixed with broken waste tablets of different diameters into the waste removal bin. The drive motor drives the gear to rotate through the drive shaft. The gear drives the waste removal bin to rotate through the gear ring. The waste removal bin drives the tablets to rotate. With the help of the guide bar, the tablets move from right to left inside the waste removal bin. The broken tablets smaller than the small mesh aperture fall into the corresponding collection bin through the small mesh aperture. The broken tablets smaller than the medium mesh aperture fall into the corresponding collection bin through the medium mesh aperture. The diameter of the large mesh aperture is equal to the diameter of the tablet. When the complete tablet moves to the position of the large mesh aperture, the complete tablet falls into the corresponding collection bin through the large mesh aperture. This is to collect the intact medicine and complete the removal of broken tablets. Then, pull out the corresponding pull box to take out the broken tablets and complete tablets. This realizes multi-level screening to remove broken tablets of different sizes, which facilitates the classification and collection of broken tablets and improves the convenience of tablet waste removal.

[0021] (2) After the tablet removal operation is completed, the inner wall of the waste removal bin will be covered with tablet dust. In order to avoid contamination of the tablets due to dust accumulation, an external air source can be connected to the adapter sleeve. The external air source is pumped through the adapter sleeve to the inside of the curved air blowing pipe. The gas is sprayed out from the nozzle through the curved air blowing pipe. Since the nozzle is close to the inner wall of the waste removal bin, the dust adhering to the inner wall of the waste removal bin can be blown out. The stepper motor drives the worm to rotate, and the worm drives the curved air blowing pipe to rotate through the worm wheel. The curved air blowing pipe drives the nozzle to rotate, thereby adjusting the blowing position to facilitate comprehensive blowing and cleaning of the dust on the inner wall of the waste removal bin. This facilitates flexible adjustment of the blowing and cleaning position and improves the cleaning effect of adhering dust. Attached Figure Description

[0031] Example 1

[0032] Please see Figure 1-5 This utility model provides an embodiment of a waste rejection mechanism for a high-speed tablet press, comprising a collection box 1 and a waste rejection frame 2. The waste rejection frame 2 is located at the top of the collection box 1, and a waste rejection bin 5 is located inside the waste rejection frame 2, with the waste rejection bin 5 movably connected to the waste rejection frame 2. A transfer frame 3 is located on the outer wall of the waste rejection frame 2, and a transfer sleeve 21 is located at the center of the transfer frame 3. A drive seat 6 is located on the side of the transfer frame 3 near the waste rejection bin 5, and a drive motor 4 is located on the outer wall of the waste rejection frame 2 on one side of the transfer frame 3, providing power. The drive motor 4 has a drive shaft 13 at its output end. A gear 12 is fitted on the surface of the drive shaft 13. A toothed ring 11 is fitted on the surface of the waste bin 5 on one side of the gear 12, and the toothed ring 11 meshes with the gear 12. The surface of the waste bin 5 has multiple sets of large mesh holes 14 at equal intervals. The surface of the waste bin 5 on one side of the large mesh holes 14 has multiple sets of medium mesh holes 15 at equal intervals. The surface of the waste bin 5 on one side of the medium mesh holes 15 has multiple sets of small mesh holes 16 at equal intervals. The inner wall of the waste bin 5 has multiple sets of guide strips 10 at equal intervals.

[0033] The collection box 1 below the waste bin 5 is equipped with three sets of collection bins 8, and the three sets of collection bins 8 correspond one-to-one with the large mesh 14, the medium mesh 15, and the small mesh 16 respectively.

[0034] Each collection bin 8 has a sliding pull-out box 7 inside, and the pull-out box 7 can be pulled out from inside the collection box 1;

[0035] The tablets, mixed with broken waste pieces of different diameters, are poured into the waste removal bin 5. The drive motor 4 is turned on, and the drive motor 4 drives the gear 12 to rotate through the drive shaft 13. With the meshing of the gear 12 and the gear ring 11, and the movable cooperation between the waste removal bin 5 and the waste removal frame 2, the gear 12 drives the waste removal bin 5 to rotate through the gear ring 11. The waste removal bin 5 drives the tablets to rotate. With the cooperation of the guide bar 10, the tablets move from right to left inside the waste removal bin 5. The broken tablets smaller than the small mesh 16 fall into the corresponding collection bin 8 through the small mesh 16, and the broken tablets smaller than the medium mesh 15 fall into the corresponding collection bin 8. Broken tablets fall into the corresponding collection bin 8 through the middle mesh 15. The diameter of the large mesh 14 is equal to the diameter of the tablet. When a whole tablet moves to the position of the large mesh 14, the whole tablet falls into the corresponding collection bin 8 through the large mesh 14, thus collecting the intact medicine and removing the broken tablets. Then, the corresponding pull-out box 7 is pulled out to take out the broken tablets and the whole tablets. This realizes multi-level screening to remove broken tablets of different sizes, which facilitates the classification and collection of broken tablets and improves the convenience of tablet waste removal.

[0036] A stepper motor 18 is provided on the side wall of the drive base 6. The stepper motor 18 plays the role of power drive. A worm gear 9 is installed at the output end of the stepper motor 18, and the worm gear 9 is movably connected to the drive base 6.

[0037] A curved air pipe 17 is movably installed inside the drive seat 6 on one side of the worm gear 9, and the curved air pipe 17 extends into the interior of the waste removal bin 5, and the curved air pipe 17 is movably connected to the waste removal bin 5.

[0038] A worm wheel 19 is fitted on the surface of the curved air pipe 17 on one side of the worm 9, and the worm 9 and the worm wheel 19 mesh with each other. A nozzle 20 is provided at the port of the curved air pipe 17.

[0039] After the tablet removal operation is completed, tablet dust will adhere to the inner wall of the waste removal bin 5. To avoid contamination of the tablets due to dust accumulation, an external air source can be connected to the adapter sleeve 21. The external air source is pumped through the adapter sleeve 21 to the inside of the curved air blowing pipe 17 via an air pump. The air is then sprayed out from the nozzle 20 through the curved air blowing pipe 17. Since the nozzle 20 is close to the inner wall of the waste removal bin 5, it can blow out the dust adhering to the inner wall of the waste removal bin 5. At the same time, the stepper motor 18 is turned on, which drives the worm 9 to rotate. Under the mutual meshing of the worm 9 and the worm wheel 19, the worm 9 drives the curved air blowing pipe 17 to rotate through the worm wheel 19. The curved air blowing pipe 17 drives the nozzle 20 to rotate, thereby adjusting its blowing position to facilitate comprehensive blowing and cleaning of the dust on the inner wall of the waste removal bin 5. This allows for flexible adjustment of the cleaning position and improves the effect of blowing and cleaning the adhering dust.

[0040] Work steps

[0041] The tablets mixed with broken fragments of different diameters are poured into the waste removal bin 5. The drive motor 4 drives the gear 12 via the drive shaft 13, which in turn drives the waste removal bin 5 via the gear ring 11. The waste removal bin 5 then rotates the tablets. With the assistance of the guide bar 10, the tablets move from right to left inside the waste removal bin 5. Fragments smaller than the small mesh 16 fall through the small mesh 16 into the corresponding collection bin 8, and fragments smaller than the medium mesh 15 fall through the medium mesh 15 into the corresponding collection bin 8. The large mesh 14 has a diameter equal to the tablet diameter. When a complete tablet moves to the position of the large mesh 14, it falls through the large mesh 14 into the corresponding collection bin 8, thus collecting the intact tablets and removing the broken fragments. Afterwards, the corresponding pull-out box 7 is pulled out. After removing the broken and intact tablets, the inner wall of the waste removal bin 5 will be covered with tablet dust. To prevent dust accumulation from contaminating the tablets, an external air source can be connected to the adapter sleeve 21. The external air source is pumped through the adapter sleeve 21 to the inside of the curved air blowing pipe 17. The gas is then sprayed out from the nozzle 20 through the curved air blowing pipe 17. Since the nozzle 20 is close to the inner wall of the waste removal bin 5, it can blow out the dust adhering to the inner wall of the waste removal bin 5. The stepper motor 18 drives the worm gear 9 to rotate, and the worm gear 9 drives the curved air blowing pipe 17 to rotate through the worm wheel 19. The curved air blowing pipe 17 drives the nozzle 20 to rotate, thereby adjusting its blowing position to facilitate comprehensive air blowing and cleaning of the dust on the inner wall of the waste removal bin 5. The above is the complete usage of the waste removal mechanism of the high-speed tablet press.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
