Description

Technical Field

[0001] This utility model relates to the field of potassium persulfate pharmaceutical production technology, specifically a feeding mechanism for a potassium persulfate tableting equipment. Background Technology

[0002] Potassium persulfate, as a strong oxidizing agent, has wide applications in water treatment, textile printing and dyeing, papermaking, food processing, and other industries. In industrial production, potassium persulfate is usually made into solid tablets or granules for easy storage, transportation, and use. This process relies on specialized tableting equipment. However, after tableting, the tablets still need to be canned. Before canning, the tablets need to be weighed to ensure that the weight of each bottle of tablets meets the standard. Traditional potassium persulfate tableting equipment simply allows the material to fall out of the equipment by gravity after tableting. It does not have the function of weighing the produced tablets according to the bottle specifications. It only guides the produced tablets, which is not very practical. At the same time, after the raw materials are pressed into tablets, the existing tableting equipment has a tight fit between the tablets and the mold cavity, resulting in high friction. The mold cavity space is also small, which is not conducive to removing the formed tablets from the mold cavity. In addition, there may be residues in the mold cavity, which will cause the weight of each tablet to deviate. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a feeding mechanism for a potassium persulfate tableting equipment. The feeding component weighs the tablets while feeding them, and the number of tablets is controlled by weighing. This can greatly improve the accuracy of the number of tablets in each bottle during the bottling process, speed up production, and reduce manual intervention. Secondly, the demolding component pushes the tablets out of the mold cavity as a whole during tablet compression, and cleans the residue on the inner wall of the mold cavity, improving the continuity of the overall tableting process and thus improving the efficiency of the production line.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1-6 As shown, a feeding mechanism for a potassium persulfate tableting equipment includes: an equipment cabinet 1, a protective frame 11 fixedly connected to the top of the equipment cabinet 1, an installation plate 12 on the top of the equipment cabinet 1, a forming mold 13 on the installation plate 12, a stamping mold 14 above the forming mold 13, and an equipment cavity 15 inside the equipment cabinet 1; a feeding assembly located inside the equipment cavity 15 for dispensing the formed tablets; and a demolding assembly located on the installation plate 12 for ejecting the formed tablets from the stamping mold 14.

[0028] The protective frame 11 has a raw material cylinder 5 fixedly installed on its top, and a feeding pipe 51 fixedly connected to the bottom of the raw material cylinder 5. The bottom end of the feeding pipe 51 extends into the equipment cabinet 1 and is opposite to the mold cavity of the forming mold 13. A hydraulic rod 52 is fixedly installed on the top of the protective frame 11, and the bottom end of the hydraulic rod 52 is connected to the top of the stamping mold 14. A gantry frame 4 is fixedly connected to the top of the equipment cabinet 1. Fixed blocks 41 are fixedly connected to the opposite sides of the gantry frame 4. Guide rods 42 are fixedly connected between the top of the two fixed blocks 41 and the top of the inner part of the gantry frame 4. Two symmetrically arranged guide blocks 43 are fixedly connected to the outside of the stamping mold 14. The two guide blocks 43 are slidably connected to the outside of the two guide rods 42.

[0029] Potassium persulfate raw material is poured into raw material cylinder 5, and added to the mold cavity of molding mold 13 through feeding pipe 51. Molding mold 13 is rotated by demolding component. While molding mold 13 is rotating, raw material is continuously added to the mold cavity of molding mold 13. Hydraulic rod 52 is activated once every time molding mold 13 rotates between two mold cavities. After hydraulic rod 52 is activated, it pushes stamping mold 14 to the lower end. Stamping mold 14 drives two guide blocks 43 to move outside guide rod 42, so that stamping mold 14 can move down smoothly. The punch at the bottom of stamping mold 14 punches into the mold cavity of molding mold 13, thereby pressing the raw material of medicine powder in the mold cavity of molding mold 13 into tablets. The tablets are pushed out of the mold cavity of molding mold 13 and collected by feeding component. When the collected tablets reach the set weight, the tablets flow out to complete the feeding, which facilitates the subsequent tablet bottling.

[0030] Example 2

[0031] Based on Embodiment 1, the feeding assembly includes: a feeding cylinder 2, a conveyor belt 21, a feeding trough 22, a sliding plate 23, a rotating plate 24, and a weighing platform 25. The feeding cylinder 2 is provided inside the equipment cavity 15. The conveyor belt 21 is provided between the inner walls of the feeding cylinder 2 on both sides. The feeding trough 22 is opened at the top of the equipment cavity 15. The top of the feeding cylinder 2 is connected to the bottom of the feeding trough 22. The sliding plate 23 is fixedly connected to one side of the inner wall of the feeding cylinder 2. The rotating plate 24 is rotatably connected between the inner walls of the feeding trough 22 on both sides. The weighing platform 25 is provided at the top of the rotating plate 24. The installation groove 26 is opened on one side of the feeding trough 22. A multi-axis cylinder 27 is provided on one side of the installation groove 26. A baffle 28 is fixedly connected between one end of the piston rod of the multi-axis cylinder 27. A support plate 29 is provided inside the installation groove 26. One end of the piston rod of the multi-axis cylinder 27 passes through the support plate 29.

[0032] After the tablets are compressed and formed, they fall onto the weighing platform 25. A gravity sensor inside the weighing platform 25 continuously monitors the weight of the tablets. As the compressed tablets fall onto the weighing platform 25, when the weight reaches the set gram weight, the multi-axis cylinder 27 activates, causing the support plate 29 to retract into the mounting groove 26. The support plate 29 supports the piston rod, causing the weighing platform 25 to lose support and rotate counterclockwise. The tablets on the weighing platform 25 slide into the feed cylinder 2 and onto the sliding plate 23. The sliding plate 23 cushions the falling height of the tablets, which then slide down onto the conveyor belt 21. The conveyor belt 21 outputs tablets from the feeding cylinder 2. The amount of tablets output each time meets the weight requirement of each bottle of tablets. This allows for simultaneous feeding and weighing of the tablets. By controlling the number of tablets through weighing, the accuracy of the number of tablets in each bottle during bottling can be greatly improved. This can speed up production, reduce manual intervention, and thus improve the efficiency of the overall production line. After the tablets above the weighing platform 25 slide down and are cleared, the weight returns to zero. At this time, the multi-axis cylinder 27 is activated and pushes out the baffle 28 from inside the mounting groove 26, pushing the weighing platform 25 to rotate clockwise until the horizontal feeding chute 22 is closed, thereby continuing to receive tablets for weighing.

[0033] Example 3

[0034] Based on Embodiment 1, the demolding assembly includes: a storage cavity 3, a through hole 31, a movable cavity 32, a fixed plate 33, and a rotating rod 34. The storage cavity 3 is located at the bottom of the mounting plate 12 near the material discharge groove 22. The bottom of the storage cavity 3 communicates with the top of the material discharge groove 22. The top of the storage cavity 3 has a through hole 31. The punch of the stamping die 14, opposite to the through hole 31, is approximately the same length as the mold cavity of the forming die 13. One of the forming holes of the stamping die 14 aligns with the through hole 31. The movable cavity 32 is located inside the mounting plate 12. A fixed plate 33 is fixedly installed at the bottom of the mold 13. A rotating rod 34 is fixedly connected to the bottom axis of the mold 13. The bottom end of the rotating rod 34 extends into the interior of the movable cavity 32 and is rotatably connected to the fixed plate 33. A driven gear 35 is fixedly connected to the periphery of the rotating rod 34. The rotating shaft at the top of the driven gear 35 is connected to the bottom axis of the mold 13. A reducer 36 is provided inside the equipment cavity 15. The drive shaft at the top of the reducer 36 extends into the interior of the movable cavity 32 and is fixedly connected to the drive gear 37. The drive gear 37 meshes with the driven gear 35.

[0035] The reducer 36 drives the drive gear 37 to rotate, which meshes with the driven gear 35, thus driving the driven gear 35 to rotate. The driven gear 35 drives the rotating rod 34 and the forming mold 13 to rotate. The rotation of the forming mold 13 is controlled by starting and stopping the reducer 36. Each rotation of the forming mold 13 increases the distance between two adjacent mold cavities, thereby making the filling, stamping, tablet demolding, and unloading processes continuous, improving processing efficiency. When pressing tablets, the forming mold 13 rotates and continuously fills its mold cavity with raw materials. With each rotation of the forming mold 13, it performs stamping and lifting actions, thus forming the tablets. The raw material in the mold cavity of mold 13 is pressed into a tablet shape. When the tablet is pressed into a block and rotates with the forming mold 13, it is aligned with the through hole 31. Since the punch of the stamping mold 14, which is aligned with the through hole 31, is relatively long, it will push the tablet out of the mold cavity when it punches in. Since the punch is matched with the mold cavity and the length is consistent, it can push the tablet out as a whole and clean the residue on the inner wall of the mold cavity. The tablet falls into the through hole 31 and then into the storage cavity 3. The tablet falls onto the weighing platform 25. Subsequent tablets continue to fall in. When the weight reaches the target, the forming mold 13 stops rotating. After the weighed tablet is unloaded, the forming mold 13 continues to operate to complete the demolding of the tablet.
