Description

Technical Field

[0001] The invention relates to the technical field of medicine production, in particular to a batching device and a batching mixing method for capsule production. Background Art

[0002] The mixing of ingredients in capsule production is a key step in the drug preparation process. It involves uniformly mixing the active ingredient (i.e. the drug itself) with various excipients in a certain proportion to ensure the quality stability and efficacy of the capsule. In the mixing process of the existing capsule production mixing device, all the raw materials are added to the mixer according to the formula ratio, the mixer is started, and the mixing is carried out according to the set parameters. The mixing state is observed during the mixing process to ensure uniform mixing. The mixing time is determined according to the characteristics of the raw materials, the type of mixer and the mixing effect. Usually, the mixing time is between a few minutes and tens of minutes.

[0003] Since the ingredients of capsules may contain many different types of raw materials, such as powders, granules, semi-solids, etc., these raw materials may have large differences in physical properties (such as particle size, density, hygroscopicity) and chemical properties (such as pH value, reactivity, etc.), resulting in poor compatibility during the mixing process and difficulty in uniform mixing. Some raw materials may also have properties such as viscosity, electrostatics or hygroscopicity, which may cause agglomeration, caking or stratification during the mixing process, resulting in poor mixing uniformity, requiring extended mixing time, and low mixing efficiency. Therefore, a batching device and a batching mixing method for capsule production are designed here to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a batching device and a batching mixing method for capsule production to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a batching device for capsule production, comprising:

[0011] The feeding screw is reversed to guide the ingredients downward in the guide tube. The ingredients enter from the guide port above the guide tube, flow out from the guide port below the guide tube, and flow back into the ingredient tube again.

[0012] In a further embodiment, a motor for providing rotational power to the feed screw is embedded in the bottom wall of the cover.

[0015] The crossbeam moves in a circle in the guide tube with the feeding screw as the rotation center. The roller rotates through the radial bottom wall of the support rod and lifts the support rod upward. When the roller rotates over the support rod, the support rod loses its lifting force and falls automatically. The crossbeam drives the guide tube to adjust its position synchronously up and down, thereby adjusting the height of the guide tube in the batching tube and changing the height of the guide port of the guide tube for introducing and exporting batching.

[0016] In a further embodiment, the side wall of the roller away from the cross beam is a half-elliptical structure, and the radial side wall of the roller is in line contact with the radial side wall of the support rod.

[0020] When the guide tube is raised and lowered to adjust the height, the supporting plate is raised and contacts the pressing plate, and the two extrusion side walls fit together to extrude and crush the ingredients.

[0022] The upper end surface of the scraper is provided with a downwardly curved arc-shaped inclined surface, and the height of the end of the arc-shaped inclined surface away from the feeding screw is higher than the height of the end close to the feeding screw.

[0023] In a further embodiment, a plurality of slots are provided on the bottom wall of the cover near the edge, and a plurality of plugs respectively plugged into each slot are fixed on the upper edge of the dispensing barrel.

[0024] Preferably, a method for mixing ingredients using a batching device for capsule production based on the above-mentioned method comprises the following steps:

[0025] A1. Start the motor. The output end of the motor drives the feeding screw to rotate and stir the materials put into the batching barrel.

[0026] A2. The feeding screw rotates forward, and guides the ingredients upward in the guide tube. The ingredients enter from the guide port at the bottom of the guide tube, flow out from the guide port at the top of the guide tube, and flow back into the mixing tube again;

[0028] A4. The crossbeam moves in a circle in the guide tube with the feeding screw as the rotation center. The roller rotates through the radial bottom wall of the support rod and lifts the support rod upward. The roller rotates over the support rod, and the support rod loses its lifting force and automatically falls down. The crossbeam drives the guide tube to adjust its position up and down synchronously, thereby adjusting the height of the guide tube in the batching tube and changing the height of the guide port of the guide tube for introducing and exporting batching.

[0029] A5. The opposite side walls of the pressing plate and the supporting plate are the extrusion side walls for extruding the ingredients. When the guide tube is raised and lowered to adjust the height, the supporting plate is raised and contacts the pressing plate, and the two extrusion side walls fit together to extrude and crush the ingredients.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention sets the guide tube in the mixing tube in the air, forms a circulating guide channel inside and outside the guide tube, and at the same time, the guide tube can be frequently lifted up and down during the guide process, and the opening positions of the upper and lower guide ports are changed, thereby accelerating the circulating flow speed of the ingredients in different height ranges, thereby accelerating the mixing speed, shortening the mixing time, and improving the mixing efficiency, avoiding the problem of poor compatibility and difficulty in rapid and uniform mixing due to differences in the physical and chemical properties of the ingredients.

[0032] 2. The present invention adds a pressing plate and a supporting plate. When the guide tube is raised and lowered to adjust the height, the supporting plate is raised and contacts the pressing plate.

DETAILED DESCRIPTION

[0045] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0046] Embodiment, this embodiment provides a batching device for capsule production, such as Figure 1 As shown, it includes: a mixing barrel 1, a cover 11 is detachably provided on the upper end of the mixing barrel 1, and the space inside the mixing barrel 1 is used as a place for mixing capsule ingredients. The cover 11 is covered on the mixing barrel 1 to form a closed mixing space to ensure that during the mixing process, the entry of air is reduced to prevent the easily oxidizable ingredients from being oxidized during the mixing process, resulting in the ineffectiveness of the medicinal properties.

[0047] A feed screw 15 is rotatably arranged on the bottom wall of the cover 11, and a motor is embedded in the bottom wall of the cover 11 to provide rotational power for the feed screw 15. The output end of the motor extends out of the bottom wall of the cover 11 and is connected to the feed screw 15. A guide tube 2 is sleeved on the outside of the feed screw 15, and a guide gap is arranged between the inner wall of the guide sleeve and the outer wall of the feed screw 15. The upper and lower openings of the guide tube 2 are guide ports, and a circulating guide channel is formed inside and outside the guide tube 2, such as Figure 2 , Figure 3 and Figure 5 As shown, the motor is started, and the output end of the motor drives the feeding screw 15 to rotate, so as to stir the material put into the batching barrel 1.

[0048] The upper end of the guide tube 2 forms a truncated cone structure, and a plurality of suspension rods 14 are fixed on the inclined outer wall of the truncated cone structure. The cover 11 is provided with a plug hole for the suspension rod 14 to slide through. The upper end of the suspension rod 14 is threadedly connected with a fastening cap 12, and the guide tube 2 is vacated and set in the batching tube 1 through the suspension rod 14. Figure 6 As shown, the fastening cap 12 can prevent the upper end of the suspension rod 14 from sliding out of the bottom opening of the jack, and the suspension rod 14 is separated from the cover 11, so that the guide tube 2 cannot be set in the air. The guide tube 2 will fall on the inner bottom wall of the batching tube 1, and the inner bottom wall of the batching tube 1 will block the next guide port of the guide tube 2, blocking the circulation guide channel formed inside and outside the guide tube 2. The bottom end of the feeding screw 15 rotates inside the guide tube 2, and can only mix and stir the ingredients located in the guide tube 2, and cannot perform contact stirring operations on the ingredients located between the outer wall of the guide tube 2 and the inner wall of the batching tube 1, resulting in poor mixing uniformity and prolonged mixing time.

[0049] Specifically, the motor can be a servo motor. When the output end of the servo motor drives the feeding screw 15 to rotate forward, the feeding screw 15 rotates in the guide tube 2. While stirring the ingredients, the feeding screw 15 rotates forward to generate a spiral upward vortex, and then the ingredients in the bottom layer of the batching tube 1 enter from the guide port below the guide tube 2, pass through the guide tube 2, and then flow out from the guide port above the guide tube 2, and then flow back to the batching tube 1 to mix with the ingredients on the upper layer. In this process, the ingredients located at the bottom layer of the batching tube 1 can be guided upward, and some of the ingredients will be transmitted upward to the upper layer along the outer wall of the feeding screw 15 and mixed with the ingredients on the upper layer. The ingredients located in the upper layer of the batching tube 1 are guided downward along the outside of the guide tube 2, and the ingredients on the upper layer compensate for the ingredients on the lower layer, so as to realize the up and down mixing operation of the materials in the inner and outer circulation of the guide tube 2.

[0050] When the output end of the servo motor drives the feeding screw 15 to reverse, the feeding screw 15 rotates in the guide tube 2. While stirring the ingredients, the feeding screw 15 reverses to generate a vortex that spirals downward, and then the ingredients in the upper layer of the batching tube 1 enter from the guide port above the guide tube 2, pass through the guide tube 2, and then flow out from the guide port below the guide tube 2, and then flow back into the batching tube 1 to mix with the ingredients in the bottom layer. In this process, the ingredients in the upper layer of the batching tube 1 can be guided downward, and some of the ingredients will be transmitted downward to the lower layer along the outer wall of the feeding screw 15 and mixed with the ingredients in the lower layer. The ingredients in the lower layer of the batching tube 1 are guided upward along the outside of the guide tube 2 to compensate for the ingredients in the upper layer, realizing the up and down mixing operation of the materials in the inner and outer circulation of the guide tube 2.

[0051] Moreover, the bottom wall of the cover 11 here extends with a plug-in end that can be tightly inserted into the upper opening of the batching barrel 1. When the motor output end drives the feeding screw 15 to rotate, if the mixed ingredients are viscous, the motor and the cover 11 may rotate by themselves, and the feeding screw 15 may adhere to the ingredients and cannot rotate. In order to solve the above problem, the cover 11 is provided with a plurality of slots 16 at a position near the edge of the bottom wall of the cover 11 at the upper end of the batching barrel 1, and a plurality of plugs 13 are fixed at the upper edge of the batching barrel 1, which are respectively plugged into each slot 16. Figure 1 and Figure 5 As shown, when the plug end of the cover 11 is inserted into the upper opening of the batching barrel 1, the slot 16 is aligned with the plug 13, and the plug 13 is inserted into the slot 16 to prevent the cover 11 from rotating synchronously with the output end of the motor at the upper end of the batching barrel 1. If the cover 11 is not moved, the motor will not rotate. As long as the motor is started, the output end can drive the feeding screw 15 to rotate to mix and flip the materials up and down.

[0052] In summary, by vacating the guide tube 2 in the batching tube 1, a circulating guide channel is formed inside and outside the guide tube 2. At the same time, the guide tube can be frequently lifted up and down during the guide process, and the opening positions of the upper and lower guide ports are changed, thereby accelerating the circulation flow speed of the ingredients in different height ranges, thereby accelerating the mixing speed, shortening the mixing time, and improving the mixing efficiency, avoiding the problem of poor compatibility and difficulty in rapid and uniform mixing due to differences in the physical and chemical properties of the ingredients.

[0053] In this embodiment, in order to further improve the mixing efficiency, a crossbeam 18 is fixed to the radial outer wall of the feeding screw 15, and a roller 19 is rotatably provided on the end side wall of the crossbeam 18. A support rod 21 is rotatably provided on the inner wall of the truncated cone structure through a pin, and the axis of the support rod 21 is distributed along the radial direction of the guide tube 2, such as Figure 4 and Figure 6 As shown, during the synchronous rotation of the feed screw 15 following the motor output end, the crossbeam 18 makes a circular motion in the guide tube 2 with the feed screw 15 as the rotation center, and the roller 19 rotates through the radial bottom wall of the support rod 21, lifting the support rod 21 upwards. The roller 19 rotates over the support rod 21, and the support rod 21 loses its lifting force and automatically falls. In this process, the crossbeam 18 will drive the guide tube 2 to adjust its position synchronously up and down, and then adjust the height of the guide tube 2 in the batching tube 1, and change the height of the guide port of the guide tube 2 for introducing and exporting the batching.

[0054] Specifically, when the roller 19 rotates and passes through the radial bottom wall of the support rod 21, the support rod 21 lifts the support rod 21 upward, and drives the guide tube 2 upward to rise through the crossbeam 18. At this time, the height of the upper and lower guide ports of the guide tube 2 located in the batching tube 1 rises synchronously, regardless of whether the feeding screw 15 rotates forward or reversely, that is, regardless of whether the material is fed from the lower guide hole and discharged from the upper guide hole, or the material is fed from the upper guide port and discharged from the lower guide hole, the height position of the feed and discharge changes. Frequently lifting and lowering the guide tube 2 can frequently change the height position of the feed and discharge, and ingredients of different heights will flow along the circulating guide channel. The frequent flow of ingredients of different heights can further speed up the mixing efficiency of the ingredients mixed together in the batching tube 1 and shorten the mixing time.

[0055] The side wall of the roller 19 away from the cross beam 18 is a half-elliptical structure, and the radial side wall of the roller 19 is in line contact with the radial side wall of the support rod 21. In this way, the contact surface of the roller 19 when rolling over the radial side wall of the support rod 21 is reduced, thereby reducing the rolling friction.

[0056] The outer wall of the suspension rod 14 is provided with a spring located between the fastening cap 12 and the cover 11, and the upper end of the spring is fixedly connected to the bottom wall of the fastening cap 12, such as Figure 1As shown, the purpose of setting the spring here is that during the process of the flow guide tube 2 being raised and lowered, the suspension rod 14 and the fastening cap 12 are adjusted up and down synchronously, so that the fastening cap 12 threadedly sleeved on the upper end of the suspension rod 14 is pushed upward in real time through the elasticity of the spring, and the suspension rod 14 has an elastic force to lift upward, and at the same time, the spring plays a buffering role between the fastening cap 12 and the cover 11, so as to avoid the suspension rod 14 from impacting and colliding with the upper end surface of the cover 11 during the lifting process, thereby generating a large noise.

[0057] Since the ingredients of capsules may contain a variety of different types of raw materials, such as powders, granules, semi-solids, etc., these raw materials are not easy to be fully mixed with other ingredients during the mixing process due to their large particles and the longer time it takes to dissolve compared to liquids. This results in poor mixing uniformity and the need to extend the mixing time.

[0058] In order to solve the above problems, a pressing plate 110 is fixedly sleeved on the outer wall of the feeding screw 15, and a supporting plate 22 is fixedly sleeved on the outer wall of the upper end of the guide tube 2. The side walls opposite to the pressing plate 110 and the supporting plate 22 are extrusion side walls for extruding ingredients. Figure 7 , Figure 8 and Fig. 9 As shown, when the feed screw 15 is rotating, the feed screw 15 rotates forward to generate a spiral upward vortex, which then causes the ingredients in the bottom layer of the batching barrel 1 to enter from the diversion port below the guide barrel 2, pass through the guide barrel 2, and then flow out from the diversion port above the guide barrel 2, and flow back to the batching barrel 1 again to mix with the ingredients in the upper layer. In this process, the ingredients flowing out from the diversion port above the guide barrel 2 will pass through the space between the pressing plate 110 and the supporting plate 22. Then, when the guide barrel 2 is raised and lowered to adjust the height, the supporting plate 22 is raised and contacts the pressing plate 110, and the two extrusion side walls fit together to extrude and crush the ingredients. By adding the pressing plate 110 and the supporting plate 22, when the guide barrel 2 is raised and lowered to adjust the height, the supporting plate 22 is raised and contacts the pressing plate 110, and the two extrusion side walls fit together to extrude and crush the ingredients. For granular ingredients, the mixing efficiency can be accelerated and the mixing time can be shortened by extrusion and crushing.

[0059] Of course, a material collecting cavity 110a which is bent upward and recessed can also be provided on the bottom wall of the pressing plate 110 near the feeding screw 15, and a plurality of guide plates 110b are fixed to the inner wall of the material collecting cavity 110a. Fig.10 and Fig.11As shown, the forward rotation of the feeding screw 15 generates a spiral upward vortex, which then causes the ingredients on the bottom layer of the batching barrel 1 to enter from the guide port below the guide barrel 2, pass through the guide barrel 2, and then flow out from the guide port above the guide barrel 2, and flow back to the batching barrel 1 again to mix with the ingredients on the upper layer. In this process, the ingredients flowing out from the guide port above the guide barrel 2 will first flow upward into the collection chamber 110a. Since the pressing plate 110 rotates synchronously with the feeding screw 15, the guide plate 110b will push the ingredients in the collection chamber 110a to make a circular motion. The ingredients are affected by the rotation of the guide plate 110b and synchronously generate a rotational centrifugal force, and are thrown out from the opening at the bottom of the collection chamber 110a in a radial direction, passing through the space between the pressing plate 110 and the supporting plate 22. When the guide barrel 2 is raised and lowered to adjust the height, the supporting plate 22 is raised and contacts the pressing plate 110, and the two extrusion side walls fit together to extrude and crush the ingredients. The purpose of this method is to provide rotational centrifugal force for the ingredients, thereby accelerating the speed at which the ingredients are squeezed and crushed between the pressing plate 110 and the supporting plate 22, so as to further improve the mixing efficiency.

[0060] The above two extrusion crushing methods are only applicable to the method in which the feeding screw 15 rotates forward to mix the ingredients from bottom to top.

[0061] A plurality of scrapers 17 are fixed to the bottom end of the radial outer wall of the feeding screw 15. The scrapers 17 rotate synchronously with the feeding screw 15 to stir the ingredients retained in the bottom layer of the batching barrel 1. While stirring, they can push the ingredients in the bottom layer to change position. On the one hand, it speeds up the position change of the ingredients in the bottom layer to improve the mixing efficiency. On the other hand, it prevents the sticky ingredients from adhering to the bottom wall of the batching barrel 1, affecting the accuracy of the final mixing ratio of the ingredients.

[0062] Moreover, the upper end surface of the scraper 17 is provided with a downwardly curved arc-shaped inclined surface, and the height of the end of the arc-shaped inclined surface away from the feeding screw 15 is higher than the height of the end close to the feeding screw 15. The purpose of such design is to utilize the outer wall of the end of the scraper 17 away from the feeding screw 15 to rotate and fit with the bottom end of the inner radial side wall of the batching barrel 1, so that the bottom end of the inner radial side wall of the batching barrel 1 can be scraped off during rotation to prevent sticky ingredients from adhering to the inner bottom radial side wall of the batching barrel 1. The purpose of the lower height of the end close to the feeding screw 15 is, on the one hand, to scoop up the ingredients by rotating the side wall of the scraper 17, and on the other hand, to prevent the end of the scraper 17 close to the feeding screw 15 from being too high, thereby forming a blocking surface under the feeding screw 15. When the feeding screw 15 rotates forward, a spiral vortex that guides the ingredients upward is generated. When the spiral vortex drives the ingredients spiral to guide upward, it touches the blocking surface, affecting the amount of ingredients guided upward.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
