Description

Technical Field

[0001] The invention relates to the technical field of microcapsule molding, and in particular to a molding auxiliary device based on microcapsule granulation and a molding process thereof. Background Art

[0002] Microcapsules are small particles containing active ingredients or core materials surrounded by a covering layer or shell. The molding process mainly includes material preparation, glue preparation, encapsulation operation, curing and subsequent treatment. The encapsulation material is an important condition that determines the solubility and storage of the core material. Therefore, continuous experimental exploration is required to prepare microcapsule products with different properties and uses.

[0003] In the prior art, the encapsulation material and the active ingredient are usually mixed in liquid form and then added dropwise to the solidifying phase in the stirring process for solidification. The commonly used stirring method in the laboratory is magnetic stirring, which can fully mix the components of a small volume of liquid and achieve the required uniformity. However, in the microcapsule forming experiment, the adsorption of droplets needs to be assisted by charges, and the magnetic stirrer will generate a magnetic field when working. This magnetic field may interfere with the adsorption and separation process of the charge, resulting in uneven formation or irregular shape of the microcapsules. The disturbance caused by the stirring may also cause the droplets to deform or rupture during the dripping process, thereby affecting the quality and shape of the microcapsules.

[0004] In addition, during solidification, as the gel particles in the culture dish accumulate, in order to avoid excessive shear force that would destroy the stability of the solidified phase, the stirring force is usually not too strong. As a result, the particles tend to contact each other, resulting in insufficient contact between the gel particles and the solidified phase, which increases the solidification time and affects the progress of the experiment.

[0005] In view of this, the present invention proposes a molding auxiliary device based on microcapsule granulation and a molding process thereof to make up for and improve the deficiencies of the prior art. Summary of the invention

[0011] Preferably, the hydraulic stirring mechanism also includes a mesh basin slidably connected to the inner wall of the gel bath tub, a material guide plate is slidably connected to the outer wall of the gel bath tub, the side of the material guide plate away from the gel bath tub is fixedly connected to the bottom of the arch frame, a baffle is fixedly connected to the middle of the mesh basin, and a pair of convex plates are fixedly connected to the top edge of the mesh basin.

[0012] Preferably, the hydraulic stirring mechanism also includes a discharge port opened on the side wall of the drain basin, the discharge port is opened on the side close to the guide plate, a plurality of first leakage holes are opened on the side of the bottom of the drain basin close to the discharge port, a plurality of second leakage holes are opened on the side of the bottom of the drain basin away from the discharge port, and the first leakage holes and the second leakage holes are arranged perpendicular to each other.

[0013] Preferably, the vibration auxiliary mechanism includes a pair of connecting rods fixedly connected to the bottom of the rotating shaft, and the sides of the pair of connecting rods away from each other are fixedly connected to extrusion blocks, and the bottoms of the two extrusion blocks are fixedly connected to rollers, and the bottom surface of the base is provided with an annular groove, and the outer walls of the two rollers are slidably connected to the annular groove, and a pair of arc blocks are symmetrically fixedly connected to the bottom of the gel bathtub, and the outer walls of the extrusion blocks and the arc blocks abut against each other.

[0014] Preferably, the vibration auxiliary mechanism also includes a plurality of limit rods equidistantly fixedly connected to the bottom of the gel bath tub, a shock-absorbing pad is slidably sleeved on the outer wall of the middle portion of the limit rod, the bottom of the limit rod is slidably connected to the inner wall of the base, the bottom of the shock-absorbing pad is fixedly connected to the outer wall of the base, and the top of the shock-absorbing pad abuts against the bottom of the gel bath tub.

[0016] Preferably, the inclined pipe, the straight pipe and the water inlet are interconnected.

[0017] Preferably, the bottom of the drain basin is tilted and the baffle is annular.

[0018] A molding process based on microcapsule granulation comprises the following steps:

[0019] Step 1: Material preparation and glue solution preparation: first prepare polysaccharide encapsulation materials and the active ingredients to be encapsulated, then dissolve the encapsulation materials in suitable solvents, stir evenly, and prepare glue solutions with different numbers;

[0020] Step 2: Encapsulation operation: Add the active ingredients to different glue solutions in sequence, stir and mix them evenly, and then put the glue solutions with different numbers into the extruder in sequence. Since the voltage is applied to the needle of the extruder, the glue solution inside is affected by the surface tension and electric field force, and the external force pushes, the liquid will break and shrink under the surface tension, and then drip into the solid phase liquid under the arch frame to form tiny gel particles;

[0021] Step 3: Curing and post-processing: Pre-select curing agents suitable for different encapsulation materials, and use a machine base to create good curing conditions for the curing process to ensure the stability and performance of the microcapsules. Conduct control experiments to select the optimal combination of glue liquids, and place the encapsulated droplets in the curing agent to further solidify them into stable microcapsules. Then, wash and dry the cured microcapsules to remove residual solvents. Finally, screen and grade the microcapsules to obtain microcapsule products that meet the requirements.

[0022] Step 4: Comparison of results: Comparison of the addition of acrylic acid / allyl methacrylate copolymer AMP salt and the absence of such copolymers. Three predicted results are: first, the addition of copolymers can make the microbeads more regular in shape and smoother in surface; second, the addition of copolymers can make the microspheres smaller at the same voltage, liquid flow rate, and polysaccharide concentration; third, the introduction of copolymers will slow down the release of the encapsulated substances; then, the predicted conclusions are drawn and an experimental manual is formed, and samples of the cured microcapsules are retained.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the microcapsule granulation experiment, the hydraulic stirring mechanism is set up to use an inclined tube to stir the solid phase liquid, which does not interfere with the charge magnetic field of the DC high-voltage power supply. At the same time, compared with traditional stirring, under the action of hydraulic pressure, when the inclined tube rotates, its top outlet pressure is small, the liquid flow rate is fast, and the bottom water inlet pressure is large and the flow rate is slow, so that the liquid at the bottom center of the gel bathtub is continuously sucked in and then discharged from the top, forming a surging cycle. The stirring speed should be moderate to avoid excessive shear force that destroys the stability of the solid phase. At the same time, when the droplets continuously fall to the stirring center of the solid phase, they can be pushed to the edge of the gel bathtub by the force of the liquid rotation and surging, effectively preventing the unsolidified droplets from sticking to each other, thereby improving the quality of the microcapsules and the uniformity of the shape;

[0025] 2. After the dripping liquid solidifies to form gel particles, the gel particles are filtered out from the solidified phase through the setting of the colander. Since the bottom of the colander is inclined, and the inclination angle of the bottom of the colander from far away from the guide plate to close to the guide plate is set from high to low, the gel particles can roll out from the discharge port along the bottom slope of the colander, which is convenient for discharge;

[0026] The first leakage hole and the second leakage hole are arranged perpendicular to each other, so that the gel particles at the second leakage hole can accelerate rolling along the hole groove direction to prevent accumulation. When reaching the first leakage hole, the liquid adhering to the outer wall of the gel particles can be intercepted laterally by the first leakage hole, thereby weakening the mutual adsorption of the gel particles, making it easier for them to pass through the discharge port, and at the same time reducing the loss of the solidified phase liquid, so that the liquid in the gel bath can continue to be reused;

[0027] 3. Through the setting of the vibration auxiliary mechanism, while the shaft rotates, the extrusion block can continuously extrude the arc block, so as to achieve the purpose of slight vibration of the gel bath, the colander and the solidified phase in the gel bath. Therefore, during the curing process, the vibrating solidified phase can disperse the mutual distance between the gel particles, so that the solidified phase can fully wrap the particles and reduce the curing time. During the discharging process, the vibration of the colander can assist the full discharge of the gel particles, cooperate with the external feeder to automatically fill the filler at the extruder, continuously manufacture microbeads, form a continuous process of preparing microbeads and quantitative discharging, avoid the interruption of the experiment to collect microbeads in the prior art, and prevent the residual gel particles from mixing with the next batch of gel, affecting the accuracy of the experiment, and ultimately improving the overall experimental rate.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1 of the present invention

[0046] Please refer to Figures 1 to 10 As shown:

[0047] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a molding auxiliary device based on microcapsule granulation, including a machine base 1, an extruder 2 is fixedly connected to the top of the machine base 1, an arch 3 is fixedly connected to the bottom surface of the machine base 1, and a DC high-voltage power supply 4 is fixedly connected to the inner wall of the bottom of the machine base 1. The DC high-voltage power supply 4 connects the extruder 2 and the arch 3 to each other, and also includes:

[0048] A hydraulic stirring mechanism 5, used to flip and stir the solidified phase and quickly discharge the material by liquid pressure;

[0049] A vibration auxiliary mechanism 6, used for continuously preparing micro beads and automatically feeding the micro beads continuously;

[0050] The hydraulic stirring mechanism 5 includes a servo motor 54 fixedly connected to the inner wall of the base 1, a rotating shaft 513 fixedly connected to the top of the servo motor 54, a gel bathtub 51 rotatably penetrated by the top of the rotating shaft 513, and the top of the rotating shaft 513 extends to the bottom of the inner cavity of the gel bathtub 51, a main gear 512 is fixedly connected to the end of the rotating shaft 513 away from the servo motor 54, a sub-gear 511 is meshingly connected to the outer wall of the main gear 512, an inclined tube 55 is fixedly connected to the top of the sub-gear 511, and a straight tube 515 is rotatably connected to the bottom of the sub-gear 511, the bottom of the straight tube 515 is fixedly connected to the inner wall of the gel bathtub 51, and a plurality of water inlets 514 are evenly spaced around the circumference of the bottom of the straight tube 515;

[0051] The hydraulic stirring mechanism 5 also includes a mesh basin 52 slidably connected to the inner wall of the gel bath 51, a material guide plate 53 is slidably connected to the outer wall of the gel bath 51, and the side of the material guide plate 53 away from the gel bath 51 is fixedly connected to the bottom of the arch 3, a baffle 510 is fixedly connected to the middle of the mesh basin 52, and a pair of convex plates 56 are fixedly connected to the top edge of the mesh basin 52;

[0052] The hydraulic stirring mechanism 5 also includes a discharge port 57 opened on the side wall of the drain basin 52. The discharge port 57 is opened on a side close to the guide plate 53. A plurality of first leakage holes 58 are opened on a side of the bottom of the drain basin 52 close to the discharge port 57. A plurality of second leakage holes 59 are opened on a side of the bottom of the drain basin 52 away from the discharge port 57. The first leakage holes 58 and the second leakage holes 59 are arranged perpendicular to each other.

[0053] The inclined pipe 55, the straight pipe 515 and the water inlet 514 are connected to each other;

[0054] The bottom of the drain basin 52 is tilted, and the baffle 510 is annularly arranged;

[0055] Among them: the inclination angle of the bottom of the drain basin 52 from far away from the guide plate 53 to close to the guide plate 53 is set from high to low, which is used for the automatic rolling and discharge of microcapsules. The baffle 510 is consistent with the axis of the sub-gear 511, and the radius of the baffle 510 is greater than the outer diameter length of the inclined tube 55.

[0056] The effects achieved by this embodiment are as follows: In the prior art, a magnetic stirrer generates a magnetic field when working, and this magnetic field may interfere with the adsorption and separation process of charges, resulting in uneven formation or irregular shape of microcapsules, and the disturbance caused by stirring may also cause the droplets to deform or rupture during the dripping process, thereby affecting the quality and shape of the microcapsules. Compared with the prior art, through the implementation of this embodiment, a hydraulic stirring mechanism 5 is set up to use an inclined tube 55 to stir the solidified phase liquid, without interfering with the charge magnetic field of the DC high-voltage power supply 4. At the same time, compared with traditional stirring, under the action of hydraulic pressure, the liquid at the bottom center of the gel bath 51 is continuously sucked in and then discharged from the top, forming a surging cycle. When the droplets continuously fall to the stirring center of the solidified phase, they can be pushed toward the edge of the gel bath 51 by the force of the liquid rotation and surging, effectively preventing the droplets that have not yet solidified from sticking to each other.

[0057] For further examples, please refer to Figure 2 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 As shown:

A pair of arc blocks 63 are symmetrically fixedly connected to the bottom of the gel bathtub 51, and the outer walls of the extrusion blocks 66 and the arc blocks 63 abut against each other.

[0059] The vibration auxiliary mechanism 6 also includes a plurality of limit rods 62 equidistantly fixedly connected to the bottom of the gel bath 51, a shock-absorbing pad 61 is slidably sleeved on the outer wall of the middle portion of the limit rod 62, the bottom of the limit rod 62 is slidably connected to the inner wall of the base 1, the bottom of the shock-absorbing pad 61 is fixedly connected to the outer wall of the base 1, and the top of the shock-absorbing pad 61 abuts against the bottom of the gel bath 51;

[0060] The shock absorbing pad 61 is arranged in a ring shape;

[0061] The inner diameter of the shock-absorbing pad 61 is greater than the outer diameter of the pair of arc blocks 63 to avoid movement obstruction.

[0062] The effects achieved by this embodiment are as follows: In the prior art, the stirring force is usually not too great, so the particles tend to contact each other, resulting in insufficient contact between the gel particles and the solidified phase, which increases the solidification time and affects the progress of the experiment. Compared with the prior art, through the implementation of this embodiment, a vibration auxiliary mechanism 6 is provided to enable the extrusion block 66 to continuously squeeze the arc block 63 while the rotating shaft 513 rotates, so as to achieve the purpose of slight vibration of the gel bath 51, the colander 52 and the solidified phase in the gel bath 51, so that during the solidification process, the vibrating solidified phase can disperse the mutual distance between the gel particles and reduce the solidification time.

[0063] Embodiment 2 of the present invention

[0064] A molding process based on microcapsule granulation comprises the following steps:

[0065] Step 1: Material preparation and glue solution preparation: first prepare polysaccharide encapsulation materials and the active ingredients to be encapsulated, then dissolve the encapsulation materials in suitable solvents, stir evenly, and prepare glue solutions with different numbers;

[0066] Step 2: Encapsulation operation: Add the active ingredients to different glue solutions in sequence, stir and mix them evenly, and then put the glue solutions with different numbers into the extruder 2 in sequence. Since the voltage is applied to the needle of the extruder 2, the glue solution inside is affected by the surface tension and electric field force, and the external force pushes, the liquid will break and shrink under the surface tension, and then drip into the solidified phase liquid under the arch 3 to form tiny gel particles;

[0067] Step 3: Curing and post-processing: Pre-select curing agents suitable for different packaging materials, and use the machine base 1 to create good curing conditions for the curing process to ensure the stability and performance of the microcapsules. Conduct control experiments to select the optimal glue combination, and place the wrapped droplets in the curing agent to further solidify them into stable microcapsules. Then, wash and dry the cured microcapsules to remove residual solvents. Finally, screen and grade the microcapsules to obtain microcapsule products that meet the requirements.

[0068] Step 4: Comparison of results: Comparison of the addition of acrylate / allyl methacrylate copolymer AMP salt and the absence of such copolymers, three predicted results: first, the addition of copolymers can make the gellan gum microbeads more regular in shape and smoother in surface; second, after the addition of copolymers, the microspheres are made smaller at the same voltage, liquid flow rate, and polysaccharide concentration; third, the introduction of copolymers will slow down the release of the encapsulated substances; then, the predicted conclusions are drawn and the experimental manual is formed, and then the cured microcapsules are sampled;

[0076] The complete usage steps and working principle of the above embodiment are as follows:

[0077] In the initial state: the drain basin 52 is retracted inside the gel bathtub 51, the gel bathtub 51 fits the shock-absorbing pad 61, the squeezing block 66 and the arc block 63 are not in contact, and the servo motor 54 is in an off state.

[0078] Working process:

[0079] When in use, the experimenter first prepares the solidification phase solution in the gel bath 51, then starts the servo motor 54 to drive the rotating shaft 513 to rotate, and drives the main gear 512 to rotate synchronously through the rotating shaft 513. The main gear 512 can continue to drive the sub-gear 511 to rotate, so that the inclined tube 55 on the top of the sub-gear 511 also rotates. Since the inclined tube 55 is inclined and connected with the straight tube 515 and the water inlet 514, the solidification phase can be accelerated when the inclined tube 55 rotates under the action of the solidification phase liquid pressure, so that the outlet pressure at the top of the inclined tube 55 is small, the liquid flow rate is fast, and the water inlet at the bottom is The pressure at the inlet 514 is high and the liquid flow rate is slow, so that the solidified phase liquid in the gel bath 51 continuously enters the straight tube 515 from the bottom water inlet 514, and is then adsorbed by the pressure in the inclined tube 55 and discharged from the top, circulating, and cooperating with the continuous rotation and stirring of the inclined tube 55, the central surging stirring of the solidified phase is achieved. In this way, when the liquid droplets squeezed by the extruder 2 fall to the stirring center, they can be pushed to the edge of the gel bath 51 by the force of the liquid rotation and surging, which not only optimizes the traditional magnetic stirring method, but also ensures that the liquid droplets that have not yet solidified will not stick together during continuous dripping, thereby improving the quality of the microcapsules;

[0080] Furthermore, when the glue liquid has dripped off and the gel particles in the gel bath 51 have solidified, the experimenter can lift the convex plate 56 with both hands and move the colander 52 upward from the inner wall of the gel bath 51, so that the gel particles are filtered out from the solidified phase, and the solidified phase liquid flows down from the pores of the colander 52 and can be recycled in the gel bath 51. Since the bottom of the colander 52 is inclined, and the inclination angle of the bottom of the colander 52 from far away from the guide plate 53 to close to the guide plate 53 is set from high to low, the gel particles can flow along the colander The bottom slope of the basin 52 rolls out from the discharge port 57, is discharged through the guide plate 53, and proceeds to the next step, while the first leakage hole 58 and the second leakage hole 59 arranged perpendicularly to each other can assist the discharge of the gel particles. The gel particles located at the second leakage hole 59 can accelerate the rolling along the hole groove direction. When reaching the first leakage hole 58, the liquid adhered to the outer wall of the gel particles can be intercepted laterally by the first leakage hole 58, thereby weakening the mutual adsorption of the gel particles, making it easier to pass through the discharge port 57, and at the same time reducing the loss of the solidified phase liquid;

[0081] Please refer to the above working process Figures 1 to 6 , Figure 8 .

[0082] Furthermore, when the rotating shaft 513 rotates, the connecting rod 67 can also be driven to rotate. The connecting rod 67 synchronously drives the extrusion block 66 to slide at the bottom of the gel bathtub 51. The roller 65 at the bottom of the extrusion block 66 slides in the annular groove 64 to ensure stability. Whenever the extrusion block 66 reaches the position of the arc block 63, the extrusion block 66 will squeeze the arc block 63. Through a pair of arc blocks 63, the gel bathtub 51 can be steadily lifted up with a slight displacement and then fall down. When falling, the bottom of the gel bathtub 51 contacts the shock-absorbing pad 61, and the gel bathtub 51 is buffered by the elastic force of the shock-absorbing pad 61, and the gel bathtub 51 is always limited by the limit rod 62. The rotating shaft 513 is rotated in this way, and the gel bath 51 is shaken as a whole, so that the gel bath 51, the colander 52 and the solidified phase in the gel bath 51 are slightly vibrated. Therefore, during the solidification process, the vibrating solidified phase can disperse the distance between the gel particles, so that the solidified phase can fully wrap the particles and reduce the solidification time. During the discharge process, the vibration of the colander 52 can assist in the full discharge of the gel particles and prevent the residual gel particles from mixing with the next batch of gel and affecting the accuracy of the experiment. The external feeder is used to automatically fill the gel at the extruder to continuously manufacture microbeads, so that the preparation of microbeads and quantitative feeding are carried out continuously, thereby improving the experimental efficiency.

10. A molding process based on microcapsule granulation, applied to a molding auxiliary device based on microcapsule granulation according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Material preparation and glue solution preparation: first prepare polysaccharide encapsulation materials and the active ingredients to be encapsulated, then dissolve the encapsulation materials in suitable solvents, stir evenly, and prepare glue solutions with different numbers; Step 2: Encapsulation operation: Add the active ingredients to different glue solutions in sequence, stir and mix them evenly, and then put the glue solutions with different numbers into the extruder (2) in sequence. Since the voltage is applied to the needle of the extruder (2), the glue solution inside is affected by the surface tension and electric field force, and the external force pushes, the liquid will break and shrink under the action of the surface tension, and then drip into the solid phase liquid under the arch frame (3), so that it forms tiny gel particles; Step 3: Curing and post-processing: Pre-select curing agents suitable for different encapsulation materials, and use the machine base (1) to create good curing conditions for the curing process to ensure the stability and performance of the microcapsules. Perform control experiments to select the optimal combination of adhesives. Place the encapsulated droplets in the curing agent to further cure them into stable microcapsules. Then, wash and dry the cured microcapsules to remove residual solvents. Finally, screen and grade the microcapsules to obtain microcapsule products that meet the requirements. Step 4: Compare the results: Compare the addition of acrylic acid (ester) / allyl methacrylate copolymer AMP salt to the glue solution and the absence of such copolymer. The three predicted results are: first, the addition of copolymer can make the microbeads more regular in shape and smoother in surface; second, after the addition of copolymer, the microspheres will be smaller at the same voltage, liquid flow rate, and polysaccharide concentration; third, the introduction of copolymer will slow down the release of its encapsulated substances. Next, the predicted conclusions are formed into an experimental manual, and then samples of the cured microcapsules are retained.
