Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of calcium tablet production, and particularly relates to a forming and drying machine for a calcium tablet processing process. BACKGROUND

[0002] As a common preparation for preventing and improving calcium deficiency, calcium tablets are widely used in the daily calcium supplement needs of various groups of people such as children, the elderly, pregnant women and the like. In the existing calcium tablet production technology, the calcium tablets are generally granulated first, and then directly extruded into a shape by upper and lower punches, and finally dried by a drying machine to remove the moisture in the air absorbed during the forming process of the calcium tablets. Since the calcium tablets are usually solid and dense, although there are gaps between the calcium particles, the digestive fluid can only slowly penetrate from the surface of the tablet, and it is difficult to quickly enter the inside of the tablet to fully contact with the effective components, resulting in a slow dissolution rate of the calcium tablet.

[0003] The slow dissolution rate of the calcium tablet directly affects the release efficiency of the calcium element, and thus reduces the bioavailability of calcium. Part of the calcium element may not be dissolved in time and be discharged out of the body through metabolism, and thus cannot be effectively absorbed by the human body, ultimately affecting the calcium supplement effect.

[0004] To solve this problem, some equipment needs to additionally increase a drilling process after the tablet is formed, which not only increases the production process and cost, but also easily causes the tablet to be broken and the edge to be damaged. Therefore, it has become a technical problem to be solved in the industry to develop a forming device that can drill holes synchronously during the forming process of the calcium tablet and ensure the quality of the tablet. SUMMARY

[0005] To solve the problems in the prior art, the application provides a forming and drying machine for a calcium tablet processing process. By adding a hole making assembly, the cutting end of the hole making assembly can penetrate the tablet which is not completely solidified, and directly rotate and cut to form a hole in the tablet by the rotation freedom of the cutting end, realizing the integration of hole making and forming. While forming the hole and improving the dissolution rate of the calcium tablet, the production time and cost are reduced, and the problems of tablet breakage and edge damage caused by traditional drilling are avoided.

[0006] The specific technical scheme adopted by the application is as follows:

[0007] The forming and drying machine for the calcium tablet processing process comprises a rack, a pressing mechanism, a material ejecting mechanism and a drying box arranged on the rack, a forming hole is further arranged on the rack, an upper punch of the pressing mechanism and a lower punch of the material ejecting mechanism are arranged on the upper and lower sides of the forming hole respectively, calcium powder in the forming hole is formed into a tablet by extrusion of the upper punch and the lower punch, a hole making assembly is additionally arranged on the material ejecting mechanism, the cutting end of the hole making assembly has a rotation freedom, and the cutting end of the hole making assembly penetrates the tablet and rotates and cuts in the inside of the tablet to form a hole.

[0008] The pores inside the tablet have a spindle-shaped structure that is narrow at both ends and wide in the middle.

[0009] The ejector mechanism includes an ejector telescopic cylinder, which is symmetrically arranged on the left and right sides of the lower punch and fixedly connected to the lower punch. The lower punch has the freedom to move up and down along the forming hole with the help of the ejector telescopic cylinder.

[0010] The hole-making assembly includes a hole-making rod, a drive gear, and a driven gear sleeved on the hole-making rod. The lower punch has a limiting hole in the vertical direction for the hole-making rod to pass through. The hole-making rod is rotatably connected to the frame. The drive gear meshes with the driven gear. The hole-making rod has a degree of freedom of rotation thanks to the drive gear.

[0011] The hole-making rod is equipped with a cutting blade, the cutting edge of which forms the cutting end of the hole-making assembly. One end of the cutting blade is fixedly connected to the rod body of the hole-making rod, and the other end of the cutting blade is connected to the top of the hole-making rod by means of a spring. The upper punch presses the spring and drives the cutting blade to bend into an arc-shaped structure. The arc-shaped cutting blade rotates and cuts inside the tablet by means of a drive gear.

[0012] The pressurizing mechanism includes a limiting sleeve and a pressurizing drive assembly. The limiting sleeve is fixedly connected to the frame in the vertical direction and is coaxially arranged with the forming hole. The connecting end of the upper punch is hinged to the pressurizing drive assembly. The extrusion end of the upper punch has the freedom to move up and down along the forming hole with the help of the pressurizing drive assembly.

[0013] The pressurizing drive assembly includes an eccentric sleeve and a pressurizing eccentric wheel. The pressurizing eccentric wheel is sleeved inside the eccentric sleeve and is eccentrically connected to the drive shaft. The eccentric sleeve forms an elliptical motion trajectory by means of the eccentric rotation of the pressurizing eccentric wheel. The connecting end of the upper punch is hinged to the bottom of the eccentric sleeve. The upper punch forms a degree of freedom of lifting and lowering by means of the movement of the eccentric sleeve.

[0014] The frame is also equipped with a feeding mechanism, which includes a feeding cylinder, a discharge tube, and a feeding drive assembly. The output end of the feeding cylinder extends to the surface of the forming hole via the discharge tube. The fixed end of the feeding cylinder is rotatably connected to the frame via a rotating shaft. The discharge tube has the freedom to swing back and forth along the surface of the forming hole with the rotating shaft as the center via the feeding drive assembly. The formed tablets are pushed to the surface of the forming hole by the ejector mechanism and discharged by the discharge tube.

[0015] The feeding drive assembly includes a feeding eccentric wheel, a first swing arm, and a second swing arm. The connecting end of the first swing arm is eccentrically connected to the drive shaft via the feeding eccentric wheel. The connecting end of the second swing arm is fixedly connected to the discharge tube. The free end of the second swing arm is hinged to the free end of the first swing arm. The first swing arm moves the second swing arm via the feeding eccentric wheel and drives the discharge tube to swing back and forth.

[0016] The unloading end of the frame is equipped with an unloading slide plate, and the output end of the unloading slide plate is connected to the drying chamber. The formed tablets are unloaded along the unloading slide plate and dried in the drying chamber.

[0017] The beneficial effects of this invention are:

[0018] 1. In this invention, a hole-making component is added to a traditional tablet press. The cutting end of the hole-making component can penetrate the tablet that is not fully cured, and directly rotate and cut the inside of the tablet to form a hole by means of the rotational freedom of the cutting end. There is no need to wait for the tablet to be formed and then perform secondary processing. This realizes the integration of hole making and forming, which reduces production time and cost, and avoids the problems of tablet breakage and edge defects caused by subsequent drilling. At the same time, the hole provides a channel for digestive liquid to penetrate, so that the calcium tablet can be dissolved in both directions at the same time, which improves the dissolution rate of calcium tablets and ensures the calcium supplementation effect.

[0019] 2. The holes formed on the tablet in this invention are spindle-shaped holes. Compared with the ring structure, they not only have the same high specific surface area to ensure the dissolution rate of the tablet, but their narrow structure at both ends can also reduce the damage of the holes to the structural integrity of the upper and lower end faces of the tablet, ensuring the connection strength between the upper and lower regions of the tablet. While ensuring that the digestive liquid can penetrate into the tablet, the tablet has sufficient structural strength and reduces the risk of breakage.

[0020] Meanwhile, the spindle-shaped pores connect to the outside world only through narrow openings on the top and bottom surfaces of the tablet, while the wider pores in the middle are located inside the tablet and do not directly contact the outside. The narrow openings reduce the contact area between the pores and the outside air, slowing down the rate at which moisture in the air penetrates into the tablet, thus significantly improving the tablet's moisture-proof performance.

[0021] 3. The hole-making component in this invention uses a bendable cutting blade to make holes. When the upper punch squeezes the calcium powder downwards, it will simultaneously press the spring at the top of the hole-making rod. The spring contracts and drives the free end of the cutting blade to bend, so that the blade as a whole forms an arc-shaped structure that bulges outwards from the middle. At this time, the drive gear drives the hole-making rod to rotate, and the arc-shaped blade rotates and cuts inside the tablet, thereby forming a spindle-shaped hole that is narrow at both ends and wide in the middle.

[0022] After the calcium tablet is formed, the upper punch resets, the spring recovers its deformation, and the free end of the blade returns to its initial state. At this time, the blade re-adheres to the hole-making rod, and then the lower punch moves upward, pushing the formed tablet upward and away from the hole-making rod. After the tablet is completely removed from the forming hole, it is unloaded, the lower punch resets, and waits for the next tablet to be formed. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0033] Specific embodiments, such as Figures 1-3As shown, the present invention provides a forming and drying machine for calcium tablet processing, including a frame 1 and a pressurizing mechanism, a feeding mechanism and a drying chamber 23 disposed on the frame 1. The frame 1 is also provided with a forming hole 2. The upper punch 3 of the pressurizing mechanism and the lower punch 4 of the feeding mechanism are respectively disposed on the upper and lower sides of the forming hole 2. The calcium powder in the forming hole 2 is formed into tablets by the extrusion of the upper punch 3 and the lower punch 4. A hole-making component is added to the feeding mechanism. The cutting end of the hole-making component has a degree of freedom of rotation. The cutting end of the hole-making component penetrates the tablet and rotates to cut the inside of the tablet to form a hole 24.

[0034] The slow dissolution rate of calcium tablets directly affects the release efficiency of calcium, thus reducing its bioavailability. Some calcium may not dissolve in time and be excreted through metabolism, failing to be effectively absorbed by the body and ultimately affecting the calcium supplementation effect. To solve this problem, some equipment requires an additional drilling process after tablet forming, which not only increases the production process and cost but also easily leads to tablet breakage and edge defects. Therefore, developing a forming equipment that can simultaneously form holes during the calcium tablet forming process while ensuring tablet quality has become an urgent technical problem to be solved in the industry.

[0035] Therefore, this invention adds a hole-making component to a traditional tablet press. The cutting end of the hole-making component can penetrate the not fully cured tablet and directly rotate and cut the inside of the tablet to form a hole 24 by means of the rotational freedom of the cutting end. There is no need to wait for the tablet to be formed and then perform secondary processing, realizing the integration of hole making and forming. This reduces production time and cost, and avoids the problems of tablet breakage and edge defects caused by subsequent drilling. At the same time, the hole 24 provides a channel for digestive fluid to penetrate, so that the calcium tablet can be dissolved in both directions simultaneously inside and outside, improving the calcium tablet dissolution rate and ensuring the calcium supplementation effect.

[0036] like Figures 2-3 As shown, the pores 24 inside the tablet have a spindle-shaped structure that is narrow at both ends and wide in the middle.

[0037] To improve dissolution speed, traditional tablets are made in ring shape. However, ring-shaped tablets not only have lower structural strength and are prone to breakage during manufacturing and transportation, but their inner ring surface is also directly exposed to air and is susceptible to moisture.

[0038] In this invention, the holes 24 formed on the tablet are spindle-shaped holes 24. Compared with the ring structure, they not only have the same high specific surface area to ensure the dissolution rate of the tablet, but their narrow structure at both ends can also reduce the damage of the hole 24 to the structural integrity of the upper and lower end faces of the tablet, and ensure the connection strength of the upper and lower regions of the tablet. While ensuring that the digestive liquid can penetrate into the tablet, the tablet has sufficient structural strength and reduces the risk of breakage.

[0039] Meanwhile, the spindle-shaped pores 24 are connected to the outside world only through narrow openings on the upper and lower end faces of the tablet, while the wider pores 24 in the middle are mainly located inside the tablet and do not directly contact the outside world. The narrow openings reduce the contact area between the pores 24 and the outside air, reducing the rate at which moisture in the air penetrates into the tablet, thereby significantly improving the moisture-proof performance of the tablet.

[0040] like Figure 1 As shown, the ejector mechanism includes an ejector telescopic cylinder 5, which is symmetrically arranged on the left and right sides of the lower punch 4 and fixedly connected to the lower punch 4. The lower punch 4 has the freedom to move up and down along the forming hole 2 with the help of the ejector telescopic cylinder 5.

[0041] The top material telescopic cylinder 5 is symmetrically arranged on both sides of the lower punch 4 to reserve installation positions for the hole-making assembly.

[0042] like Figure 1 As shown, the hole-making assembly includes a hole-making rod 6, a driving gear 7, and a driven gear 8 sleeved on the hole-making rod 6. The lower punch 4 is provided with a limiting hole 9 in the vertical direction for the hole-making rod 6 to pass through. The hole-making rod 6 is rotatably connected to the frame 1. The driving gear 7 meshes with the driven gear 8. The hole-making rod 6 has a degree of freedom of rotation by means of the driving gear 7.

[0043] The rotation of the drive gear 7 drives the driven gear 8 to rotate, thereby driving the hole-making rod 6 to rotate synchronously, providing rotational freedom for the cutting blade 10; a sealing ring is provided at the limiting hole 9 to prevent calcium powder from overflowing along the limiting hole 9 during the calcium powder extrusion molding process.

[0044] like Figure 1 and Figures 4-7 As shown, a cutting blade 10 is provided on the hole-making rod 6. The cutting edge of the cutting blade 10 forms the cutting end of the hole-making assembly. One end of the cutting blade 10 is fixedly connected to the rod body of the hole-making rod 6, and the other end of the cutting blade 10 is connected to the top of the hole-making rod 6 by means of a spring 11. The upper punch 3 presses the spring 11 and drives the cutting blade 10 to bend into an arc-shaped structure. The arc-shaped cutting blade 10 rotates and cuts inside the tablet by means of the drive gear 7.

[0045] When the upper punch 3 presses the calcium powder downwards, it simultaneously presses the spring 11 at the top of the pressing rod 6. The spring 11 contracts and causes the free end of the cutting blade 10 to bend, as shown. Figures 6-7 As shown, the cutting blade 10 is formed into an arc-shaped structure with the middle protruding outwards; at this time, the drive gear 7 drives the hole-making rod 6 to rotate, and the arc-shaped cutting blade 10 rotates and cuts inside the tablet, thereby forming a spindle-shaped hole 24 that is narrow at both ends and wide in the middle.

[0046] After the calcium tablet is formed, the upper punch 3 resets, the spring 11 recovers its deformation, and drives the free end of the blade to return to its initial state, as shown below. Figures 4-5As shown, at this time, the blade re-adheres to the hole-making rod 6, and then the lower punch 4 moves upward, pushing the already formed tablet upward and detaching it from the hole-making rod 6. After the tablet is completely detached from the forming hole 2, it is unloaded, the lower punch 4 is reset, and it waits for the next tablet to be formed.

[0047] In addition, when the lower punch 4 rises to be flush with the surface of the forming hole 2, that is, when the tablet is completely separated from the forming hole 2, the end of the hole-making rod 6 is located in the limiting hole 9 of the lower punch 4 to form a blockage, so as to prevent calcium powder from leaking out along the limiting hole 9 when replenishing material.

[0048] like Figure 1 and Figure 8 As shown, the pressurizing mechanism includes a limiting sleeve 12 and a pressurizing drive assembly. The limiting sleeve 12 is fixedly connected to the frame 1 in the vertical direction. The limiting sleeve 12 is coaxially arranged with the forming hole 2. The connecting end of the upper punch 3 is hinged to the pressurizing drive assembly. The extrusion end of the upper punch 3 has the freedom to move up and down along the forming hole 2 with the help of the pressurizing drive assembly.

[0049] The limiting sleeve 12 can constrain the lifting path of the upper punch 3, preventing the upper punch 3 from shifting due to uneven force during the pressurization process, ensuring that the extrusion end of the upper punch 3 is always aligned with the forming hole 2, preventing calcium powder from leaking out from the gap between the forming hole 2 and the upper punch 3, and ensuring the tablet forming effect.

[0050] like Figure 1 and Figure 8 As shown, the pressurizing drive assembly includes an eccentric sleeve 13 and a pressurizing eccentric wheel 14. The pressurizing eccentric wheel 14 is sleeved inside the eccentric sleeve 13 and is eccentrically connected to the drive shaft 15. The eccentric sleeve 13 forms an elliptical motion trajectory by means of the eccentric rotation of the pressurizing eccentric wheel 14. The connecting end of the upper punch 3 is hinged to the bottom of the eccentric sleeve 13. The upper punch 3 forms a degree of freedom of lifting and lowering by means of the movement of the eccentric sleeve 13.

[0051] When the drive shaft 15 rotates, the pressure eccentric wheel 14 will perform eccentric motion around the drive shaft 15, thereby driving the inner eccentric sleeve 13 to form an elliptical motion trajectory. Since the connecting end of the upper punch 3 is hinged to the bottom of the eccentric sleeve 13, the vertical displacement of the elliptical trajectory will be converted into the lifting and lowering action of the upper punch 3. The pressure drive assembly can drive the continuous lifting and lowering of the upper punch 3 to meet the needs of continuous production.

[0052] like Figure 1 and Figure 8As shown, the frame 1 is also equipped with a feeding mechanism, which includes a feeding cylinder 16, a discharge tube 17, and a feeding drive assembly. The output end of the feeding cylinder 16 extends to the surface of the forming hole 2 via the discharge tube 17. The fixed end of the feeding cylinder 16 is rotatably connected to the frame 1 via a rotating shaft 18. The discharge tube 17 has the freedom to swing back and forth along the surface of the forming hole 2 with the rotating shaft 18 as the center via the feeding drive assembly. The formed tablets are pushed to the surface of the forming hole 2 by the feeding mechanism and discharged by the discharge tube 17.

[0053] After the calcium tablets are formed, the feeding mechanism pushes the tablets to the surface of the forming hole 2. At this time, the reciprocating discharge tube 17 can directly move the tablets, causing them to slide along the surface of the forming hole 2 towards the discharge end. While the discharge tube 17 moves the tablets, the lower punch 4 resets and re-exposes the forming hole 2. The calcium powder in the feeding cylinder 16 will be fed into the forming hole 2 along the discharge tube 17. After the feeding is completed, the discharge tube 17 swings back to its original position, adhering to the table near the forming hole 2 and forming a blockage, causing the feeding cylinder 16 to stop feeding.

[0054] like Figure 1 and Figure 8 As shown, the feeding drive assembly includes a feeding eccentric wheel 19, a first swing arm 20, and a second swing arm 21. The connecting end of the first swing arm 20 is eccentrically connected to the drive shaft 15 via the feeding eccentric wheel 19. The connecting end of the second swing arm 21 is fixedly connected to the discharge tube 17. The free end of the second swing arm 21 is hinged to the free end of the first swing arm 20. The first swing arm 20 moves the second swing arm 21 via the feeding eccentric wheel 19 and drives the discharge tube 17 to swing back and forth.

[0055] The feeding eccentric wheel 19 is eccentrically connected to the drive shaft 15. When the drive shaft 15 rotates, the feeding eccentric wheel 19 drives the first swing arm 20 to reciprocate. The connecting end of the second swing arm 21 is fixed to the discharge tube 17. The free end of the second swing arm 21 is hinged to the first swing arm 20, so that the swing of the first swing arm 20 can be directly transmitted to the second swing arm 21, thereby driving the discharge tube 17 to form a periodic reciprocating swing.

[0056] like Figure 1 As shown, the unloading end of the frame 1 is provided with an unloading slide plate 22. The output end of the unloading slide plate 22 is connected to the drying box 23. The formed tablets are unloaded along the unloading slide plate 22 and dried in the drying box 23.

[0057] Compared to traditional solid and dense tablets, the tablets in this invention have a higher specific surface area. During processing, they may absorb a small amount of moisture from the air, resulting in slight dampness. Therefore, the tablets need to be dried after molding to remove residual moisture before being sealed and packaged to ensure product storage stability.
