Description

Technical Field

[0001] The present invention relates to the technical field of tablet processing, in particular to a preparation process and processing equipment of compound danshen tablets. Background Art

[0002] The preparation steps of the compound Danshen tablets include: preparing raw materials, pre-processing raw materials, extracting Danshen medicinal materials, crushing borneol, granulating, mixing, tableting, film coating and inner packaging;

[0003] Since tablets are small in size, numerous in number, and stacked together during film coating, in the prior art, a coating material is sprayed onto the surface of the tablets by a spray gun, thereby forming a film coating on the surface of the tablets. However, the stacked tablets are stirred by a stirring shaft, which not only makes it difficult to stir the tablets but also causes certain damage to the tablets, thereby affecting the quality and efficiency of the tablet coating. Based on this, there are corresponding equipment treatments in the prior art. Among them, a Chinese patent (CN114028226A) discloses a high-efficiency coating machine for tablet processing. The device uses a rolling device to not only enable the tablet core to fully accept the medium for coating, thereby improving the coating efficiency of the tablet core, but also does not require a stirring shaft to stir the tablet core, thereby improving the coating quality of the tablet core. The medium can be sprayed and coated better through the stirring device, constant temperature device and drying device, thereby improving the effect of spraying with the spray gun and coating of the tablet cores. The storage device reduces the workload of the staff and improves their work efficiency. However, when a large number of chips are accumulated in the rolling device, the rotation of the rolling device only causes the chips at the bottom and the upper part to circulate together, while the chips accumulated in the middle cannot roll to the upper part of the accumulated chips. After the coating is completed, some chips are not coated. If the number of coated chips is reduced, the coating efficiency of the overall tablets will be reduced. In addition, the coating of materials such as medicines and foods with higher hygiene standards requires that the coating container be cleaned after the coating production is completed and the materials are discharged.

[0048] Example 1

[0049] A preparation and processing equipment for compound danshen tablets, such as Figure 1-13 As shown, it includes a cabin 1, a cabin door 2, a coating system, a barrel 210, an atomizing nozzle 218, a first material lifting plate 221, a second material lifting plate 222, a drying system and a hot air blower 301; the cabin door 2 is rotatably connected to the rear wall of the cabin 1; the middle of the cabin 1 is connected to the coating system; the middle of the coating system is connected to the barrel 210; three atomizing nozzles 218 are connected to the middle of the coating system, and the three atomizing nozzles 218 are equidistantly distributed; the three atomizing nozzles 218 are located inside the barrel 210; two first material lifting plates 221 are fixedly connected to the inner annular surface of the barrel 210; the two first material lifting plates 221 are each hinged with a second lifting plates 222, and the two second lifting plates 222 are in contact with each other; a torsion spring is fixedly connected to the connection between each first lifting plate 221 and each second lifting plate 222; the two second lifting plates 222 can only rotate in one direction when opened; the upper part of the cabin 1 is connected to a drying system; the drying system is connected to a hot air blower 301; the drying system is connected to the coating system; it also includes a cleaning system, a spray head 402 and a feeding system; the middle of the coating system is connected to a cleaning system; the cleaning system is connected to three spray heads 402, and the three spray heads 402 are equidistantly distributed; the bottom wall of the cabin 1 is connected to the feeding system.

[0050] The rotation described below is from front to back, from top to bottom, and from right to left. When in use, the compound danshen tablet preparation and processing equipment is first placed in the required position, and the cabin 1 is placed on a stable ground. First, the operator connects the coating raw material delivery pipe to the coating system and the water pipe to the cleaning system, controls the coating system to open the rectangular groove 210b of the barrel 210, and adds tablets to the barrel 210. Then, the coating system is controlled to operate, driving the barrel 210, the two first lifting plates 221 and the two second lifting plates 222 to rotate counterclockwise together. At the same time, the three atomizing nozzles 218 are controlled to spray the coating raw materials on the tablets below, and the coating raw materials are sprayed on the tablets through the first lifting plate 221 and the second lifting plate 2 The counterclockwise rotation of 22 forces the tablets that fall on the bottom to gather at the left and right ends of the drum 210, and moves the tablets at the bottom upward, and then falls on the top of all the tablets, while the tablets that fall on the top turn over the first lifting plate 221 and the second lifting plate 222 to the lower layer of the tablets. This cycle is repeated so that the outer surfaces of all tablets are evenly sprayed with the coating material. At the same time, the hot air blower 301 is controlled to start and blow hot air into the drum 210 through the drying system, so that the coating material sprayed on the surface of the tablets is quickly dried to form a film coat. Then the drying system is controlled to transport the hot air in the cabin 1 to the outside, so that the temperature inside the drum 210 is maintained at an appropriate level to prevent the film coat wrapped on the tablets from melting again.

[0051] When the tablets in the drum 210 are coated with a uniform film, the coating system is controlled to rotate clockwise with the drum 210, the first lifting plate 221 and the second lifting plate 222. When the two first lifting plates 221 rotate to the bottom, the tablets in the drum 210 are forced to gather in the middle. The tablets gathered in the middle will push the two second lifting plates 222 to open. When the rectangular groove 210b of the drum 210 rotates to face downward, the tablets are located on the rectangular groove 210b, and the unloading system is controlled to collect the film-coated tablets. Then the coating system is controlled to open the rectangular groove 210 of the drum 210. 10b, so that the contents of the barrel 210 are poured out and enter the feeding system. When there are no tablets in the barrel 210, the coating system is controlled to close the barrel 210 and rotate the barrel 210. Then, the cleaning system is controlled to clean the inner annular surface of the barrel 210 through the three spray heads 402. After the barrel 210 is clean, the feeding system is controlled again to collect the cleaned water, and the drying system is controlled to dry the inner annular surface of the barrel 210. This solves the problem of stirring a large number of tablets through the stirring shaft, which not only makes it difficult to stir a large number of tablets, but also causes certain damage to the tablets, thereby affecting the quality and efficiency of the tablet coating.

[0066] A preparation process of compound danshen tablets, comprising the following steps:

[0067] Step 1: Manual loading: First, manually open the feed port 1b, control the coating system to open the rectangular slot 210b, and pour the tablets into the barrel 210;

[0068] Step 2: Spraying the coating material, the tablets are circulated and rolled together through the coating system, and the atomizing nozzle 218 is controlled to spray the coating material on the tablets;

[0069] Step 3: Drying the coating material: Control the hot air blower 301 to start, and blow hot air through the blowing pipe 304 to the tablets sprayed with the coating material below, so that the coating material on the surface of the tablets is quickly dried to form a film coat;

[0070] Step 4: Collect the tablets. The tablets are rolled by the coating system so that they gather in the middle. The tablets in the drum 210 are poured into the collection box 505 for collection.

[0071] Step 5: Cleaning and drying the drum 210 , controlling the cleaning system to clean the inner surface of the drum 210 , and then controlling the hot air blower 301 to dry the remaining moisture on the inner surface of the drum 210 .

[0072] like Figure 1-7 As shown, the coating system works as follows:

[0073] First, the operator connects the coating raw material conveying pipe to the first circular tube 216 and the water pipe to the second circular tube 401, manually grabs the baffle 201 and moves it upwards to open the feed port 1b of the cabin 1, controls the first electric push rod 203 to push out, drives the first guide plate 204 to move upwards, so that the first guide plate 204 coincides with the feed port 1b and the rectangular groove 210b, and then controls the second electric push rod 213 to retract, drives the first connecting plate 214 and the sealing plate 215 to move to the left together, and opens the circular tube 216. The operator pours the tablets onto the first guide plate 204 into the barrel 210. After adding appropriate tablets into the barrel 210, the operator controls the first electric push rod 203 to retract, driving the connected components to reset. Then, the operator controls the second electric push rod 213 to push out, driving the connected components to reset, closing the rectangular slot 210b of the barrel 210. The operator manually grabs the baffle 201 and pulls it down to close the feed port 1b of the cabin 1.

[0074] When the feed port 1b of the cabin 1 is closed, since a large number of tablets are piled up in the drum 210, the drum 210 rotates, and only the tablets at the bottom and the upper part are rolled together, while the tablets piled up in the middle cannot roll to the upper part of the piled tablets, resulting in some tablets being difficult to turn over to the upper part of the tablets and spraying the coating raw materials. Therefore, the output shaft of the control motor 206 rotates clockwise, driving the spur gear 207 to rotate clockwise, and the spur gear 207 drives the first ring plate 209, the drum 210, the gear ring 209 and the gear ring 209. 11. The fixed block 212, the second electric push rod 213, the first connecting plate 214, the sealing plate 215, the first V-shaped arc plate 219, the second V-shaped arc plate 220, the first lifting plate 221, the second lifting plate 222, the sliding rod 406, the second ring plate 407 and the elastic member 408 rotate counterclockwise together. At the same time, the three atomizing nozzles 218 are controlled to spray the coating raw materials toward the tablets below. The first V-shaped arc plate 219, the second V-shaped arc plate 220, the first lifting plate 221 and the second lifting plate During the counterclockwise rotation of 222, the two second lifting plates 222 will not open, and the tablets falling on the bottom will be forced to gather at the left and right ends of the barrel 210 in turn, and will be carried upward by the first V-shaped arc plate 219, the second V-shaped arc plate 220, the first lifting plate 221 and the second lifting plate 222 in turn, and then fall on the top of all the tablets. Each time the tablets fall on the top, they will turn over the first V-shaped arc plate 219, the second V-shaped arc plate 220, the first lifting plate 221 and the second lifting plate 222 in turn. The second lifting plate 222 comes to the lower layer of the tablets, and the cycle continues so that the outer surfaces of all tablets are evenly sprayed with coating materials, realizing the spraying of coating materials on the tablets through the three atomizing nozzles 218 pairs, and using the first V-shaped arc plate 219, the second V-shaped arc plate 220, the first lifting plate 221 and the second lifting plate 222 to carry the bottom tablets and the upper tablets in turn for circulation and replacement, avoiding the phenomenon that some tablets cannot be sprayed with coating materials, reducing the tablet coating time and improving the coating efficiency.

[0075] like Figure 1 、 8 -9 shows how the drying system works:

[0076] At the same time, the hot air blower 301 is controlled to start, and hot air is continuously blown into the barrel 210 through the first pipe 302, the second pipe 303, and the blowing pipe 304. The hot air is blown towards the tablets below through the seven blowing pipes 304, so that the coating material sprayed on the surface of the tablets is quickly dried to form a film coating. After the blowing pipe 304 continues to blow hot air into the barrel 210 for a period of time, the hot air in the barrel 210 will pass through the several special-shaped grooves 209a of the first ring plate 209 and the second ring plate 4 07's several strip grooves 407a come to the outside of the barrel 210, and then the exhaust fan 305 is controlled to open, and the hot air in the cabin 1 is extracted out through the third pipe 306, so that the cabin 1 maintains an appropriate temperature. After the coating materials sprayed on all the tablets in the barrel 210 are dried to form a film coat, the hot air blower 301 and the exhaust fan 305 are controlled to close to avoid the temperature in the barrel 210 being too high, which will cause the film coat wrapped on the tablets to melt again, affecting the appearance and quality of the tablets.

[0077] like Figure 1-7 、 Figure 13 As shown, the coating system and feeding system work as follows:

[0078] When all the tablets in the barrel 210 are film-coated, since the rectangular groove 210b is located in the middle of the barrel 210, it is impossible to pour out all the tablets inside through the rectangular groove 210b of the barrel 210. Therefore, the output shaft of the control motor 206 rotates counterclockwise, driving the connected parts to rotate together. When the first V-shaped arc plate 219, the second V-shaped arc plate 220, and the first lifting plate 221 rotate clockwise to the bottom in sequence, the tablets in the barrel 210 are forced to gather in the middle. The tablets that are forced to gather in the middle by the two first lifting plates 221 The tablet will push the two second lifting plates 222 to open. When the rectangular groove 210b rotates to face downward, the tablet is located on the rectangular groove 210b, the output shaft of the control motor 206 stops rotating, and the two fourth electric push rods 502 are controlled to push out, driving the connecting bracket 503 and the second guide plate 504 to move upward together, so that the second guide plate 504 fits the outer surface of the barrel 210 and is located below the rectangular groove 210b. The second electric push rod 213 is controlled to retract, driving the connected parts to move together, and the rectangular groove of the barrel 210 is opened. 210b, let the tablets in the barrel 210 fall down onto the second guide plate 504, and follow the guidance of the second guide plate 504 into the collection box 505. Because the two second lifting plates 222 are opened, the tablets carried by the two first lifting plates 221 also fall onto the second guide plate 504. After all the tablets in the barrel 210 enter the collection box 505, the two second lifting plates 222 automatically reset under the action of the torsion spring, and the two fourth electric push rods 502 contract, driving the connected components to reset, and the second electric push rod 2 13 is also pushed out, driving the connected parts to reset, closing the rectangular groove 210b of the barrel 210, and the operator takes away the collection box 505, replaces it with a new collection box 505 and puts it back in place, so that the two first lifting plates 221 rotate clockwise to gather the tablets in the barrel 210 in the middle, and push the two second lifting plates 222 to open, so as to prevent the two second lifting plates 222 from blocking the tablets in the barrel 210 and preventing them from falling into the rectangular groove 210b, which in turn requires manual collection, takes a long time and is inefficient.

[0079] like Figure 1-12 As shown, the working mode of coating system, drying system and cleaning system is as follows:

[0080] At this time, due to the coating of medicines, foods and other materials with high hygiene standards, it is required that the coating container needs to be cleaned after the coating production is completed and the materials are discharged. Therefore, the two sealing components are operated synchronously. Taking the sealing component on the left as an example, the two third electric push rods 403 are controlled to be pushed out, driving the second connecting plate 404 and the ring 405 to move to the right, pushing the second ring plate 407 to move to the right on the four sliding rods 406, forcing the four elastic members 408 to be compressed, so that the second ring plate 407 and the first ring plate are connected. 209 is fitted, and several special-shaped grooves 209a on the first ring plate 209 are closed. Another sealing component is operated in the same way as the sealing component on the left, and several special-shaped grooves 209a on the other first ring plate 209 are closed. Then the three spray heads 402 are controlled to spray water on the inner ring surface of the barrel 210, and the inner ring surface of the barrel 210 is flushed by the sprayed water. At the same time, the output shaft of the motor 206 is controlled to rotate clockwise, driving the connected components to rotate together, flushing the inner ring surface of the barrel 210. After washing the inner annular surface of the drum 210, the waste water will gather at the bottom of the drum 210. At the same time, the drum 210 drives the first V-shaped arc plate 219, the second V-shaped arc plate 220 and the first lifting plate 221 to rotate together. The first V-shaped arc plate 219, the second V-shaped arc plate 220 and the first lifting plate 221 hit the waste water at the bottom of the drum 210, causing the waste water at the bottom of the drum 210 to be agitated. If there are impurities on the inner annular surface of the drum 210 that have not been washed off by the three spray heads 402, The stirred waste water is used to impact and dislodge the tablets. When the inner ring surface of the barrel 210 is cleaned and the rectangular groove 210b of the barrel 210 is rotated downward again, the output shaft of the motor 206 is controlled to stop rotating, so that the second ring plate 407 blocks the several special-shaped grooves 209a of the first ring plate 209. Then, the three spray heads 402 are controlled to clean the inner ring surface of the barrel 210, thereby avoiding the problem of waste water used to clean the inner ring surface of the barrel 210 flowing out of the barrel 210 and tablet residue remaining on the inner ring surface of the barrel 210.

[0081] After the inner surface of the drum 210 is cleaned, the two fourth electric push rods 502 are controlled to be pushed out, driving the connected parts to move upward, and the second guide plate 504 comes to the bottom of the rectangular groove 210b again, and the second electric push rod 213 is controlled to be retracted, driving the connected parts to move, opening the rectangular groove 210b of the drum 210, so that the waste water in the drum 210 flows into the new collection box 505 through the second guide plate 504. Because the first V-shaped arc plate 219, the second V-shaped arc plate 220 and the first lifting plate 221 are all provided with a plurality of guide holes, the waste water remaining on the first V-shaped arc plate 219, the second V-shaped arc plate 220 and the first lifting plate 221 will be collected again through the plurality of guide holes. The waste water gathers at the bottom of the barrel 210. After the waste water in the barrel 210 is drained, the fourth electric push rod 502 and the second electric push rod 213 are controlled to drive the connected parts to reset, and the four third electric push rods 403 are controlled to contract to drive the connected parts to reset, and the barrel 210 is no longer closed. Finally, the hot air blower 301 is controlled to blow out hot air to dry the inner ring surface of the barrel 210. After the inner ring surface of the barrel 210 is dried, the hot air blower 301 is controlled to be turned off, and the waste water is poured into the new collection box 505 for collection through the second guide plate 504. The hot air blower 301 is controlled to dry the inner ring surface of the barrel 210 to prevent the waste water remaining on the inner ring surface of the barrel 210 from breeding bacteria, resulting in the barrel 210 failing to meet the hygiene standards.
