DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] As Figures 1 to 6 shown, the present utility model provides a vitamin C chewable tablet production device, including:

[0026] Frame 1, the inner wall of the frame 1 is fixedly connected with a motor 3, the output shaft of the motor 3 is fixedly connected with one end of a central shaft 4, the other end of the central shaft 4 is fixedly connected with an upper mold frame 8, the other end of the central shaft 4 is fixedly connected with a lower mold frame 13, the side of the central shaft 4 is fixedly connected with a middle mold frame 10, a plurality of holes are formed in the upper mold frame 8, and an upper mold 9 is sleeved in the holes, a plurality of through holes are formed in the middle mold frame 10, and a middle mold 11 is sleeved in the through holes, a plurality of holes are formed in the side of the middle mold frame 10, and fixing bolts 12 are installed so that the middle mold 11 will not break away from the middle mold frame 10, a plurality of holes are formed in the lower mold frame 13, and a lower mold 14 is sleeved in the holes, the lower end of the lower mold 14 is placed on a slide rail 20, the slide rail 20 is fixedly connected inside the frame 1, the slide rail 20 is concentric with the central shaft 4, a rotating shaft 18 is fixedly connected inside the frame 1, one end of the rotating shaft 18 is sleeved with a reed 17, a torsion spring 19 is fixedly connected inside the reed 17, and the reed 17 contacts the upper mold 9 when the upper mold 9 falls.

[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, the upper mold frame 8, the middle mold frame 10 and the lower mold frame 13 are all fixedly connected to the central shaft 4, the output shaft of the motor 3 is connected to one end of the central shaft 4, the holes of the upper mold frame 8 are sleeved with the upper mold 9, the holes of the middle mold frame 10 are sleeved with the middle mold 11, and the holes of the lower mold frame 13 are sleeved with the lower mold 14. This enables the rotation of the motor 3 to drive the central shaft 4 to rotate through the output shaft, and then drive the upper mold frame 8, the middle mold frame 10 and the lower mold frame 13 to rotate. The holes formed in the side of the middle mold frame 10 enable the middle mold 11 to be fixed inside the middle mold frame 10 with the fixing bolts 12 and will not fall off after the middle mold 11 is installed on the middle mold frame 10.

[0028] During the operation of the equipment, the upper mold frame 8 rotates to make the upper mold 9 rotate and collide with the reed 17. At this time, the tablets or particles adhered to the upper mold 9 are shaken off by the vibration generated by the collision. When the reed 17 is no longer in contact with the upper mold 9, it returns to the initial position via the torsion spring 19 inside the reed 17 to collide with the next upper mold 9 to clean the tablets or particles adhered to the upper mold 9.

[0029] Among them, a blanking chute 21 is installed on the upper surface of the middle mold frame 10. One end of the blanking chute 21 close to the central shaft 4 is provided with a groove, and a movable plate 16 is placed in the groove. One end of the movable plate 16 is connected with a knob 15, and the distance between the movable plate 16 and the surface of the middle mold frame 10 is adjusted by rotating the knob 15.

[0030] As Figure 3 and Figure 4As shown in the figure, a slot for accommodating the movable plate 16 is provided at one end of the blanking chute 21 near the central axis 4. One end of the movable plate 16 is connected with a knob 15. By rotating the knob 15, the height of the movable plate 16 can be controlled. After replacing the upper die 9, the middle die 11 and the lower die 14, only by adjusting the height of the movable plate 16 can the filtering of the tablets at the new height be realized, without the need to replace the blanking chute 21 with different filtering sizes.

[0031] Wherein, a baffle 6 is fixedly installed inside the frame 1, and the baffle 6 is located on one side of the rotating shaft 18 to prevent the tablets and particles shaken off by the reed 17 from flying outwards.

[0032] As Figure 2 and Figure 3 shown, by setting the baffle 6, the shaken-off tablets or particles can fall onto the middle mold frame 10 instead of onto the frame 1, so that this part of the medicine can be filtered and collected by the blanking chute 21 and participate in the next production process. If it falls onto the frame 1, it will not only cause waste of medicine, but also pollute the production environment.

[0033] Wherein, a powder trough 7 is placed on the upper surface of the middle mold frame 10. One side of the powder trough 7 is bolted to one end of the fixed column 5, and the other end of the fixed column 5 is fixedly connected to the inside of the frame 1.

[0034] As Figure 3 shown, during the operation of the equipment, the powder trough 7 is responsible for receiving the powder particles transported by the feeding mechanism. It has multiple slots inside, and small openings are provided at the bottom of the partition structure of each slot, so that after one slot is filled, it will be transported to the next slot by the movement of the middle mold frame 10 through the small openings. This not only improves the capacity of the powder trough 7, but also prevents the powder particles from being insufficient in quantity when falling into the middle die 11 due to the overly large powder trough 7, resulting in the quality of the finally produced tablets not meeting the requirements.

[0035] Wherein, a pressing wheel 2 is connected inside the frame 1, and the side of the pressing wheel 2 contacts the upper end of the upper die 9 and makes the upper die 9 move downward.

[0036] As Figure 2 shown, during the rotation of the equipment, the upper die 9 in contact with the pressing wheel 2 is squeezed and dropped by the pressing wheel 2, and completes the extrusion of the drug particles with the corresponding lower die 14 in the middle die 11, completing the forming of one tablet.

[0037] Wherein, the number of holes provided in the upper mold frame 8, the middle mold frame 10 and the lower mold frame 13 is the same and they are located on the same axis.

[0038] As Figure 3 shown, the upper mold frame 8, the middle mold frame 10 and the lower mold frame 13 are provided with the same number of holes, so that during the operation of the equipment, the rotation angles of the corresponding holes are the same, preventing the mold from being misaligned and affecting the production.

[0039] Among them, the upper die 9, the middle die 11, and the lower die 14 are the same in number and the same as the number of holes on the die holder they are sleeved on. The sizes of the die heads of the upper die 9 and the lower die 14 are the same as the size of the through hole opened inside the middle die 11. The die head of the lower die 14 is always located inside the middle die 11, so that the inside of the middle die 11 can hold the powder particles.

[0040] As Figure 3 shown, the upper die 9, the middle die 11, and the lower die 14 are in a one-to-one correspondence and the same as the number of holes on the die holder. This makes it so that when the device rotates, it will not vibrate due to the center of gravity not being on the central axis 4, thereby affecting the service life of the device. Also, the sizes of the die heads of the upper die 9 and the lower die 14 being the same as the size of the holes inside the middle die 11 makes it so that when the drug particles are being extruded, they will not be squeezed out due to gaps, causing drug waste.

[0041] Among them, there is a spring in the part where the upper die holder 8 is sleeved with the upper die 9, which makes the die head of the upper die 9 away from the middle die holder 10 when the upper die 9 is not being squeezed by the pressing wheel 2.

[0042] As Figure 1 shown, when the upper die 9 is not being squeezed by the pressing wheel 2, the spring inside the upper die holder 8 is used to keep the upper die 9 in the raised state. At this time, the die head of the upper die 9 is away from the middle die holder 10, so that when the device is operating, the upper die 9 will not collide with the blanking chute 21 and the powder chute 7, causing equipment failures. At the same time, using a spring also facilitates the repair and replacement of the upper die 9.

[0043] Among them, when the lower die 14 rotates around the central axis 4, the bottom is lifted by the highest point of the slide rail 20, and the tablet on the die head of the lower die 14 is lifted to the upper surface of the middle die holder 10.

[0044] As Figure 3 shown, when the lower die 14 is operating, after contacting the slide rail 20, the die head lifts the tablet, and then the tablet is filtered by the movable plate 16 of the blanking chute 21. If the height of the tablet meets the requirements, it will fall from the right slot of the blanking chute 21 and be collected in the container, otherwise it will fall from the left side of the blanking chute 21 and be collected in the container of the recycling equipment.

[0045] The working principle of the present utility model:

[0046] When the device is running, first, the feeding mechanism is used to transport the powder particles to the powder tank 7. Then, the powder particles in the powder tank 7 will fill the inside of the middle die 11 under the action of gravity. Continuing to run, the middle die 11 filled with powder particles, along with the corresponding upper die 9 and lower die 14, will move relative to each other under the combined drive of the pressing wheel 2 and the slide rail 20, squeezing the powder particles inside to complete the production of one tablet. The central shaft 4 continues to rotate, and the upper die 9 will bounce back to its original position under the action of the spring inside the upper die holder 8. The tablet on the die head of the lower die 14 is intercepted and filtered by the movable plate 16. Before the upper die 9 returns to its original position, it will first contact the reed 17. After the reed 17 vibrates, the powder particles and the adhered tablets on the die head of the upper die 9 are shaken off. The baffle 6 prevents the shaken-off materials from falling outside the middle die holder 10. The shaken-off tablets or powder particles continue to travel on the upper surface of the middle die holder 10 until they are intercepted by the blanking chute 21 and then are sent to the recycling equipment through the recycling chute on the left side of the blanking chute 21. After the reed 17 is separated from the upper die 9, the reed 17 bounces back to its initial position under the action of the torsion spring 19 inside it. After the lower die 14 falls from the highest point of the slide rail 20, a cavity is formed between its die head and the middle die 11 for the next processing.
