Description

Technical Field

[0001] The invention relates to the technical field of Guben Yanling Pill preparation, and in particular to a Guben Yanling Pill continuous molding preparation device and a preparation method. Background Art

[0002] Guben Yanling Pills are approved Chinese medicines. This product is a large dark brown honey pill; the taste is sweet at first and then slightly bitter. The main ingredients are ginseng, ophiopogon, schisandra, asparagus, rehmannia, rehmannia root, yam, oriental water plantain, poria, achyranthes, cornus, eucommia, costusroot, polygala, cypress seed, Morinda officinalis (salted), Zanthoxylum bungeanum, calamus, salvia miltiorrhiza, cistanche, wolfberry, raspberry, lycium bark, antler glue, dodder seed, fish maw pearl, pearl, dog whip. The auxiliary material is: honey. After the above medicinal materials are dried, crushed, sterilized, mixed and processed, they are added with refined honey to make large honey pills. Functions and indications: Strengthen the body and nourish the essence, nourish yin, replenish the marrow and essence, and strengthen the tendons and bones. It is used for consumptive injuries, low back pain and fatigue, palpitations and insomnia, haggard skin, premature graying of hair and beard, irregular menstruation, and loss of appetite;

[0003] In the preparation process of Guben Yanling Pills, a treatment agent needs to be used and mixed evenly with the coarse powder of the crushed medicinal materials. In the preparation process of the treatment agent, polyethylene glycol needs to be subjected to esterification reaction with hydroxystearic acid and concentrated sulfuric acid under high temperature environment. In order to avoid oxidation of the resultant polyethylene glycol hydroxystearate, the esterification reaction needs to be carried out under nitrogen protection. However, the volume of a traditional heating box is huge. Filling the heating box with nitrogen will consume a large amount of gas, thereby increasing production costs. At the same time, after polyethylene glycol hydroxystearate is generated, low-temperature citric acid and acetic acid are added. Since the amount of citric acid and acetic acid added is large, it takes time to heat the citric acid and acetic acid to a predetermined temperature, which invisibly increases the entire production preparation time. Therefore, a person skilled in the art has proposed a continuous molding preparation device and a preparation method for Guben Yanling Pills. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a continuous molding preparation device and a preparation method for Guben Yanling Pills, which solve the problems in the above background.

[0005] To achieve the above objectives, the present invention is implemented by the following technical solutions: a continuous molding preparation device and preparation method of Guben Yanling Pills, wherein polyethylene glycol, hydroxystearic acid and concentrated sulfuric acid are placed in a closed cavity composed of a mixing drum and a placing basin for esterification reaction, and the placing basin stores materials to be added in the next process, and then the materials in the placing basin are preheated by a heating box during the esterification reaction of ethylene glycol, hydroxystearic acid and concentrated sulfuric acid, and then the materials in the placing basin are directly sent into the mixing drum in the next process to react with the product of ethylene glycol, hydroxystearic acid and concentrated sulfuric acid;

[0006] The method is realized by using a continuous forming preparation device for Guben Yanling Pills. The continuous forming preparation device for Guben Yanling Pills includes components such as a reaction mechanism, a driving mechanism, a stirring mechanism, and a fixing mechanism. The driving mechanism is arranged inside the reaction mechanism to provide power for the reaction mechanism. The stirring mechanism is installed inside the reaction mechanism to stir the materials inside the reaction mechanism. The fixing mechanism is installed on the reaction mechanism to connect and fix two components inside the reaction mechanism. It is characterized in that the reaction mechanism includes a stirring cylinder assembly and a placing basin assembly. A narrow and airtight cavity is formed by the stirring cylinder assembly and the placing basin assembly to allow polyethylene glycol to react with hydroxy stearic acid and concentrated sulfuric acid. Since the space inside the cavity becomes smaller after the materials are filled, the amount of nitrogen used is reduced. At the same time, the materials are placed in the placing basin to preheat them, reducing the time wasted in heating the materials in the subsequent reaction.

[0007] As a further technical solution of the present invention, the reaction mechanism includes a heating box. The center of the inner bottom surface of the heating box is installed with a stirring cylinder. A placing basin adapted to it is arranged directly above the stirring cylinder inside the heating box. A U-shaped frame is installed on the side surface of the placing basin. Sliding grooves are opened on both side walls of the U-shaped frame. The center of the upper surface of the heating box is installed with an electric push rod. The lower end of the electric push rod extends into the heating box to observe the U-shaped frame and is installed on a cover plate. Each sliding groove is slidably provided with a sliding rod whose side surface is fixedly connected to the cover plate.

[0008] As a further technical solution of the present invention, a center plate is installed at the center of the inner wall of the placing basin. The center plate divides the interior of the placing basin into two chamber. Rectangular holes are opened on the lower surface of the placing basin below each chamber. Cavities are opened on one side of each rectangular hole inside the bottom plate of the placing basin. A limiting plate is slidably arranged in each cavity. A spring is arranged on one side of the limiting plate in each cavity. A partition plate that extends into the adjacent rectangular hole and closes it is installed on the other side surface of each limiting plate. A center groove is opened between the two cavities inside the bottom plate of the placing basin. A winding rod is rotatably installed in the center groove. A steel wire rope that extends into the center groove and is fixedly connected to the winding rod is installed at the center of the side surface of each limiting plate. Output pipes are installed at the port of each rectangular hole on the lower surface of the placing basin.

[0009] As a further technical solution of the present invention, a three-way pipe extending outside the heating box is jointly installed on the side surfaces of the stirring cylinder and the placing basin. A first solenoid valve is installed on the three-way pipe outside the heating box. A negative pressure generator is installed on the side surface of the heating box. The output end of the negative pressure generator is installed with a connecting pipe that extends into the heating box and is communicated with the stirring cylinder. A second solenoid valve is installed on the connecting pipe outside the heating box. A multi-way pipe extending outside the heating box is also installed on the side surfaces of the stirring cylinder and the placing basin. A valve is arranged on the multi-way pipe.

[0010] As a further technical solution of the present invention, the driving mechanism includes a first motor installed on the upper surface of the heating box and on one side of the electric push rod. The driving end of the first motor extends into the heating box and is installed with a main rod. A receiving groove is opened at the lower end of the main rod. A secondary rod is slidably arranged in the receiving groove. Two strip-shaped grooves communicating with the receiving groove are correspondingly opened on the side surface of the main rod. A limiting block fixedly connected to the secondary rod is slidably arranged in each strip-shaped groove. The lower end of the secondary rod is rotatably installed with an L-shaped plate on one side of the winding rod. The lower end of the secondary rod penetrates through the L-shaped plate and is installed with a first bevel gear. One end of the winding rod extends outside the placement basin, penetrates through the L-shaped plate, and is installed with a second bevel gear meshing with the first bevel gear.

[0011] As a further technical solution of the present invention, the fixing mechanism includes mounting plates installed on both sides of the placement basin. A gear is rotatably installed on the side surface of each mounting plate. A first rack meshing with the gear is installed at the end of each sliding rod. A second rack meshing with the gear is slidably connected to the lower side of the gear on the side surface of each mounting plate. An L-shaped frame is installed on the lower surface of each second rack. A side plate is installed at the end of each L-shaped frame. A set of card slots is opened on the side surface of the stirring barrel on one side of each side plate. A card member adapted thereto is installed on the side surface of each side plate on one side of each card slot.

[0012] As a further technical solution of the present invention, the stirring mechanism includes a second motor installed at the center of the lower surface of the heating box. The driving end of the second motor is installed with a rotating rod extending into the stirring barrel. A plurality of uniformly distributed stirring blades are installed on the surface of the rotating rod.

[0013] Specifically, it includes the following steps:

[0014] S1. Connect the end of the three-way pipe to the output end of the nitrogen tank. Then open the door of the heating box, send polyethylene glycol, hydroxy stearic acid and concentrated sulfuric acid into the stirring barrel. Then put citric acid and acetic acid liquid into the two tank chambers in the placement basin. Then close the door. The electric push rod extends to drive the cover plate and the U-shaped frame to descend. The descending U-shaped frame will drive the placement basin to descend until the placement basin covers the upper port of the stirring barrel to seal the stirring barrel. Then the extending electric push rod continues to drive the cover plate to descend until the cover plate covers the upper port of the placement basin to seal the placement basin. Then open the first solenoid valve to allow nitrogen to enter the stirring barrel and the placement basin through the three-way pipe, and squeeze out the air in the stirring barrel and the placement basin through the exhaust pipe. Then close the first solenoid valve and the valve.

[0015] S2. While the cover plate descends, it will also drive two first racks to descend through two slide bars until the two first racks contact and engage with the two gears. After that, the two descending first racks will drive the two gears to rotate, and each rotating gear will also drive the engaged second rack to move, causing the two second racks to approach each other, thereby driving two sets of clamping members to approach each other until each clamping member is inserted into the corresponding card slot on the mixing drum to connect and fix the mixing drum and the placement basin. At this time, the cover plate just covers the port of the placement basin;

[0016] S3. The operating heating box heats the cavity to 100 degrees. Then, the second motor operates to drive the stirring blades to rotate through the rotating rod, stirring the polyethylene glycol, hydroxy stearic acid, and concentrated sulfuric acid in the mixing drum. The polyethylene glycol, hydroxy stearic acid, and concentrated sulfuric acid undergo an esterification reaction under high-temperature stirring conditions until polyethylene glycol hydroxy stearate is obtained. At the same time, during the reaction of polyethylene glycol, hydroxy stearic acid, and concentrated sulfuric acid, the high temperature in the heating box can preheat the citric acid and acetic acid in the placement basin;

[0017] S4. After the polyethylene glycol hydroxy stearate is obtained through the reaction, the first motor operates to drive the main rod to rotate. The rotating main rod drives the auxiliary rod to rotate through the cooperation of the strip-shaped groove and the limit block. The rotating auxiliary rod drives the winding rod to rotate through the first bevel gear and the second bevel gear. The rotating winding rod winds two steel wires to pull the two limit plates closer to each other. While each moving limit plate compresses the spring, it drives the partition plate to move out of the rectangular hole and into the cavity, thereby opening the two rectangular holes. Then, the citric acid and acetic acid in the placement basin enter the mixing drum through the corresponding rectangular holes and the output pipe. After that, the first motor drives the main rod to reverse, and through these operations, the winding rod reverses to unwind the wound steel wires, and then the two springs rebound to drive the partition plate to return to its original position until the two rectangular holes are closed;

[0018] S5. After the citric acid and acetic acid enter the mixing drum, open the second solenoid valve and the negative pressure generator. The operating negative pressure generator adjusts the vacuum degree in the mixing drum through the connecting pipe until it reaches the predetermined value. Then, the heating box increases the temperature in the cavity to 120 degrees. Then, the operating second motor drives the stirring blades to rotate to stir the polyethylene glycol hydroxy stearate, citric acid, and acetic acid in the mixing drum to make them react to obtain the citric acid esterification product. Then, open the third solenoid valve to discharge the esterification product through the output pipe to achieve continuous reaction molding;

[0019] S6. Subsequently, the electric push rod shortens to drive the cover plate to rise. The rising cover plate drives two first racks to rise through two sliding rods. Each rising first rack drives the engaged gear to rotate, and each rotating gear drives the engaged second rack to move, causing the two second racks to move away from each other, thereby driving each clamping member out of the card slot, releasing the fixation between the mixing drum and the placing basin. When the cover plate moves into contact with the U-shaped frame, the rising cover plate drives the placing basin to rise through the U-shaped frame, so that the upper port of the mixing drum opens. Then, the materials are re-put into the mixing drum and the placing basin, and continuous operation can be carried out.

[0020] Beneficial effects

[0021] The present invention provides a continuous forming preparation device and a preparation method for Guben Yanling Pills. Compared with the prior art, the following beneficial effects are achieved:

[0022] 1. A continuous forming preparation device and a preparation method for Guben Yanling Pills. A mixing drum and a placing basin are arranged in the reaction mechanism of the device. The placing basin is used to seal the upper port of the mixing drum, so that the esterification reaction occurs in the mixing drum. Since the inner cavity volume of the mixing drum is adapted to the volume of the reaction materials, only a small amount of nitrogen is needed to fill the inner cavity of the mixing drum, reducing the consumption of nitrogen, lowering the production cost. At the same time, two chambers in the placing basin for sealing the mixing drum can place citric acid and acetic acid for the next process. Furthermore, during the esterification reaction process, the heating box can preheat the citric acid and acetic acid, thereby reducing the time consumed for heating them in the next process, reducing the production time, and accelerating the working efficiency. At the same time, a fixing mechanism is also provided. When the cover plate covers the placing basin, it drives two first racks to descend, and through components, each clamping member is driven to be stuck into the aligned card slot, strengthening the connection between the placing basin and the mixing drum, avoiding the generation of gaps at the misaligned connection due to the vibration during the operation of the mixing mechanism, which affects the sealing performance inside the mixing drum. At the same time, the operating power of the fixing mechanism comes from the upper and lower cover plates, enhancing the linkage between the reaction mechanism and the fixing mechanism.

A narrow closed cavity is formed by the stirring cylinder assembly and the placement basin assembly to allow polyethylene glycol, hydroxy stearic acid and concentrated sulfuric acid to react. Since the space in the cavity becomes smaller after being filled with materials, the amount of nitrogen used is reduced. At the same time, materials are placed in the placement basin to preheat it, reducing the time wasted in heating the materials during the subsequent reaction;

When the electric push rod 5 extends, it drives the cover plate 7 and the U-shaped frame 4 to descend. The descending U-shaped frame 4 drives the placing basin 3 to descend until the placing basin 3 covers the upper port of the mixing drum 2 to seal the mixing drum 2. Then, the extending electric push rod 5 continues to drive the cover plate 7 to descend until the cover plate 7 covers the upper port of the placing basin 3 to seal the placing basin 3. Then, the first electromagnetic valve 40 is opened to allow nitrogen to enter the mixing drum 2 and the placing basin 3 through the three-way pipe 39, and the air inside the mixing drum 2 and the placing basin 3 is extruded through the exhaust pipe. Then, the first electromagnetic valve 40 and the valve are closed. After the reaction is completed, the winding rod 11 is driven to rotate by a driving mechanism.

A set of card slots 35 is opened on the side surface of the mixing barrel 2 on one side of each side plate 33. A card member 34 adapted thereto is installed on the side surface of each side plate 33 on one side of each card slot 35. During use, when the cover plate 7 descends, it will also drive the two first racks 30 to descend through the two sliding rods 8 until the two first racks 30 contact and mesh with the two gears 29. Then the two descending first racks 30 will drive the two gears 29 to rotate. Each rotating gear 29 will also drive the engaged second rack 31 to move, making the two second racks 31 approach each other, thereby driving the two sets of card members 34 to approach each other until each card member 34 is inserted into the corresponding card slot 35 on the mixing barrel 2 to connect and fix the mixing barrel 2 and the placing basin 3, and at this time the cover plate 7 just covers the port of the placing basin 3.

[0037] The stirring mechanism includes a second motor 36 installed at the center of the lower surface of the heating box 1. The driving end of the second motor 36 is installed with a rotating rod 37 extending into the mixing barrel 2. A number of uniformly distributed stirring blades 38 are installed on the surface of the rotating rod 37. During use, the second motor 36 operates to drive the stirring blades 38 to rotate through the rotating rod 37 to stir the polyethylene glycol, hydroxy stearic acid and concentrated sulfuric acid in the mixing barrel 2.

[0038] Specifically, it includes the following steps:

[0039] S1. Connect the end of the tee pipe 39 to the output end of the nitrogen tank. Then, open the door of the heating box 1, send polyethylene glycol, hydroxy stearic acid, and concentrated sulfuric acid into the mixing cylinder 2. Then, place citric acid and acetic acid liquids into the two compartments in the placement basin 3. After that, close the door. The electric push rod 5 extends to drive the cover plate 7 and the U-shaped frame 4 to descend. The descending U-shaped frame 4 will drive the placement basin 3 to descend until the placement basin 3 covers the upper port of the mixing cylinder 2 to seal the mixing cylinder 2. Then, the extending electric push rod 5 continues to drive the cover plate 7 to descend until the cover plate 7 covers the upper port of the placement basin 3 to seal the placement basin 3. Then, open the first solenoid valve 40 to allow nitrogen to enter the mixing cylinder 2 and the placement basin 3 through the tee pipe 39, and squeeze out the air in the mixing cylinder 2 and the placement basin 3 through the exhaust pipe. Then, close the first solenoid valve 40 and the valve;

[0040] S2. When the cover plate 7 descends, it will also drive the two first racks 30 to descend through the two slide bars 8 until the two first racks 30 contact and engage the two gears 29. Then, the two descending first racks 30 will drive the two gears 29 to rotate. Each rotating gear 29 will also drive the engaged second rack 31 to move, causing the two second racks 31 to approach each other, thereby driving the two groups of clamping members 34 to approach each other until each clamping member 34 is inserted into the corresponding slot 35 on the mixing cylinder 2 to connect and fix the mixing cylinder 2 and the placement basin 3. And at this time, the cover plate 7 just covers the port of the placement basin 3;

[0041] S3. The operating heating box 1 heats the cavity to 100 degrees. Then, the second motor 36 operates to drive the mixing blades 38 to rotate through the rotating rod 37 to stir the polyethylene glycol, hydroxy stearic acid, and concentrated sulfuric acid in the mixing cylinder 2. The polyethylene glycol, hydroxy stearic acid, and concentrated sulfuric acid undergo an esterification reaction under the conditions of high-temperature stirring until polyethylene glycol hydroxy stearate is obtained. At the same time, during the reaction of polyethylene glycol, hydroxy stearic acid, and concentrated sulfuric acid, the high temperature in the heating box 1 can preheat the citric acid and acetic acid in the placement basin 3;

[0042] S4. After the polyethylene glycol hydroxystearate is obtained by reaction, the first motor 19 operates to drive the main rod 20 to rotate. The rotating main rod 20 drives the auxiliary rod 22 to rotate through the cooperation of the strip groove 23 and the limiting block 24. The rotating auxiliary rod 22 drives the winding rod 11 to rotate through the first bevel gear 26 and the second bevel gear 27. The rotating winding rod 11 winds two steel wire ropes 15 to pull the two limiting plates 13 closer to each other. While each moving limiting plate 13 compresses the spring 14, it drives the partition plate 17 to move out of the rectangular hole 9 into the cavity 12, so as to open the two rectangular holes 9. Then, the citric acid and acetic acid in the placing basin 3 enter the mixing cylinder 2 through the corresponding rectangular holes 9 and the output pipe 18. After that, the first motor 19 drives the main rod 20 to reverse. Through these operations, the winding rod 11 reverses to unwind the wound steel wire ropes 15, and then the two springs 14 rebound to drive the partition plate 17 to restore its position until the two rectangular holes 9 are closed, realizing continuous reaction molding;

[0043] S5. After the citric acid and acetic acid enter the mixing cylinder 2, the second solenoid valve 43 and the negative pressure generator 41 are opened. The operating negative pressure generator 41 adjusts the vacuum degree in the mixing cylinder 2 through the connecting pipe 42 until it reaches the predetermined value. Then, the temperature in the heating chamber 1 is increased to 120 degrees. After that, the operating second motor 36 drives the mixing blades 38 to rotate to stir the polyethylene glycol hydroxystearate, citric acid and acetic acid in the mixing cylinder 2 to make them react, obtaining the citric acid esterification product. Then, the third solenoid valve 45 is opened to discharge the esterification product through the output pipe 44;

[0044] S6. Then, the electric push rod 5 shortens to drive the cover plate 7 to rise. The rising cover plate 7 drives the two first racks 30 to rise through the two slide rods 8. Each rising first rack 30 drives the engaged gear 29 to rotate.
