Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for capsule production, and in particular to a gelling device for capsule production. Background Technology

[0002] In the capsule manufacturing industry, gelatinization is a crucial step in the gelatin preparation process, and its effectiveness directly impacts the quality and efficiency of subsequent capsule production. Currently, gelatinization is typically accomplished using a gelatinization tank, a core piece of equipment. This tank uniformly dissolves and thoroughly mixes gelatin, plasticizers (such as glycerin), water, and other necessary excipients to form a homogeneous gel solution that meets the process requirements of capsule production.

[0003] However, in existing gelling tanks, the high-speed rotation of the stirring paddle during the mixing process generates a large centrifugal force. Due to the connection position being close to the top, the stirring shaft lacks sufficient support and stability, resulting in a large swaying force at the lower end of the stirring shaft under the action of centrifugal force. This not only affects the uniformity of mixing, making it difficult for the various components of the gelatin to mix fully, but may also cause wear to the stirring shaft and related parts, reduce the service life of the equipment, and affect the heating and melting state of gelatin and auxiliary materials. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a gelling device for capsule production.

[0005] The technical solution of this utility model is achieved through the following scheme: a capsule production gelling device, including a support frame, an upper mixing cylinder, a lower slurry stirring cylinder and heating support components, wherein the lower slurry stirring cylinder is fixedly installed on the support frame, the upper mixing cylinder is flange-connected to the lower slurry stirring cylinder, heating support components are installed on the support frame and are arranged opposite to each other, and the lower slurry stirring cylinder is located between the heating support components;

[0006] The upper mixing cylinder is equipped with a feeding and stirring device, which includes a first motor and a feeding rotating component. The first motor drives the feeding rotating component via a gear, and the feeding rotating component is connected to the upper mixing cylinder via a hollow support shaft.

[0007] A second rotating shaft is provided inside the lower slurry stirring drum;

[0008] The hollow support shaft is perpendicular to the second rotation shaft;

[0009] The top surface of the upper mixing cylinder is provided with several feed pipes, which intersect each other in a spiral shape to prevent material backflow.

[0010] Through the above technical solutions, the lower slurry mixing drum is clamped by the relatively set heating support components. While uniformly heating the lower slurry mixing drum, it also provides support and fixation, reducing the shaking force of the mixing. The upper mixing drum mixes the raw materials, while the lower slurry mixing drum focuses on dissolving the slurry and further mixing. The division of labor and cooperation do not affect each other, optimizing the production process, reducing the processing burden of individual drums, and improving overall production efficiency. The feed pipes intersect in a spiral shape, which can effectively prevent material backflow and ensure that the material enters the upper mixing drum smoothly for mixing. This avoids production failures and material waste caused by material backflow, ensuring the continuity and stability of production.

[0011] Preferably, the upper mixing cylinder includes an upper cylinder body and a mixing cylinder. The mixing cylinder is mounted inside the upper cylinder body by a feeding and stirring device. A feed pipe is provided on the top surface of the upper cylinder body, and the feed pipe is connected to the mixing cylinder through a feeding hopper.

[0012] Preferably, the feeding and mixing device further includes a second motor and a first mixing fan. The second motor is connected to the first mixing fan through a first rotating shaft. The second motor is fixedly installed on one side of the upper cylinder by a mounting bracket. The first rotating shaft passes through the hollow support shaft and is connected to the first mixing fan. The first mixing fan is located inside the mixing cylinder.

[0013] Preferably, the upper cylinder cavity below the mixing cylinder is provided with a discharge slope, which is connected to the lower slurry mixing cylinder.

[0014] Through the above technical solution, the mixing and feeding are separated and do not interfere with each other by the independent control of dual motors. The second motor drives the first mixing fan to rotate in the mixing drum, which fully mixes the materials entering the mixing drum, so that the components of the materials can fully contact and mix, improving the uniformity of the materials. The material is then swept for rapid feeding in the subsequent feeding process. The end of the feed hopper is arc-shaped, which allows the raw materials and auxiliary materials to slide smoothly and accurately into the mixing drum, and also effectively avoids splashing during the mixing process.

[0015] Preferably, the lower slurry mixing drum includes a lower cylinder, a third motor, several second mixing fans, and a distributing head. The lower cylinder is fixedly installed on the upper surface of the support frame mounting plate, the third motor is located on the lower surface of the support frame mounting plate, and the third motor is connected to several second mixing fans through a second rotating shaft. A distributing head is installed at the end of the second rotating shaft.

[0016] Preferably, a liquid level sensor and a temperature sensor are installed inside the lower cylinder.

[0017] Through the above technical solutions, the material is dispersed by the material distribution head, so that the material is evenly distributed in the lower cylinder. Multiple stirring fans work together to stir the material from different levels, making the mixing of the various components of the material more uniform.

[0018] Preferably, the heating support includes a plurality of linear actuators, a support cover, a plurality of shock-absorbing spring columns, and a plurality of heating plates. The plurality of linear actuators are mounted on the support frame. The convex side of the support cover is connected to the telescopic ends of the plurality of linear actuators. The concave side of the support cover is provided with a plurality of heating plates and a plurality of shock-absorbing spring columns.

[0019] Through the above technical solutions, the lower slurry mixing drum is heated in a wrap-around manner, which makes the heating of each part of the lower slurry mixing drum more even and ensures uniform heating of the slurry. The shock-absorbing spring column plays a good role in shock absorption and buffering during the operation of the lower slurry mixing drum, absorbing and dispersing vibration energy and reducing the impact of vibration on the support frame and other connecting parts.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model uses relatively arranged heating support components to clamp the lower slurry mixing drum. While uniformly heating the lower slurry mixing drum, it also provides support and fixation, reducing the shaking force of the mixing. The upper mixing drum mixes the raw materials, while the lower slurry mixing drum focuses on dissolving the slurry and further mixing. The division of labor and cooperation do not affect each other, optimizing the production process, reducing the processing burden of individual drums, and improving overall production efficiency. The feed pipes intersect in a spiral shape, which can effectively prevent material backflow and ensure that the material enters the upper mixing drum smoothly for mixing. This avoids production failures and material waste caused by material backflow, ensuring the continuity and stability of production.

[0022] 2. With independent control of dual motors, stirring and feeding are separated and do not interfere with each other. The second motor drives the first stirring fan to rotate in the mixing drum, which fully stirs the material entering the mixing drum, so that the components of the material can fully contact and mix, improving the uniformity of the material. It also sweeps the material for rapid feeding in the subsequent feeding process. The end of the feed hopper is arc-shaped, which not only allows the raw materials and auxiliary materials to slide smoothly and accurately into the mixing drum, but also effectively avoids splashing during the stirring and mixing process.

[0023] 3. The material is dispersed by the distribution head, so that the material is evenly distributed in the lower cylinder. Multiple stirring fans work together to stir the material from different levels, so that the mixture of the various components of the material is more uniform.

[0024] 4. By enveloping the lower slurry mixing drum with heating, the heating of each part of the lower slurry mixing drum is more even, ensuring uniform heating of the slurry. The shock-absorbing spring column plays a good role in shock absorption and buffering during the operation of the lower slurry mixing drum, absorbing and dispersing vibration energy, and reducing the impact of vibration on the support frame and other connecting parts.

[0036] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] A capsule manufacturing apparatus, such as Figures 1-7As shown, the assembly includes a support frame 1, an upper mixing cylinder 2, a lower slurry mixing cylinder 3, and heating support members 4. The lower slurry mixing cylinder 3 is fixedly mounted on the support frame 1. The upper mixing cylinder 2 is flange-connected to the lower slurry mixing cylinder 3. Heating support members 4 are mounted on the support frame 1 and positioned opposite each other. The lower slurry mixing cylinder 3 is located between the heating support members 4, preferably two in number, positioned on either side of the lower slurry mixing cylinder 3 to clamp it and heat it evenly. A slurry outlet pipe is located at the bottom of the lower slurry mixing cylinder 3, and a pump body is mounted on the outlet pipe. The pump body is preferably a high-viscosity pump. The heating support members 4 are adapted to the lower slurry mixing cylinder 3. The upper mixing cylinder 2 is connected to the lower slurry mixing cylinder 3 via a flange. After the materials are fully mixed in the upper mixing cylinder 2, they are lowered into the lower slurry mixing cylinder 3 for slurry mixing. The mixing also facilitates subsequent disassembly and maintenance, making it convenient for internal cleaning, inspection, or component replacement. Simultaneously, the heating supports 4 on both sides, while providing uniform heating, also offer some support and fixation to the lower slurry mixing drum 3, enhancing the stability of the mixing shaft and reducing the shaking force at the lower end. The material mixing and slurry stirring processes can be performed separately, resulting in more stable adhesive quality. The lower slurry mixing drum 3 is embedded within the mounting plate of the support frame 1. Several feed pipes are provided on the top surface of the upper mixing drum 2, intersecting in a spiral shape to prevent material backflow. Preferably, there are two feed pipes, one for raw materials and one for auxiliary materials, intersecting to form a double spiral shape. The two pipes are tightly welded together on arc surfaces for stable mutual support.

[0039] The upper mixing cylinder 2 is equipped with a feeding and stirring device 23, which includes a first motor 231 and a feeding rotating component 232. The first motor 231 drives the feeding rotating component 232 with a gear. The feeding rotating component 232 is connected to the upper mixing cylinder 2 through a hollow support shaft.

[0040] A second rotating shaft is installed inside the lower slurry mixing drum 3;

[0041] The hollow support shaft and the second rotating shaft are arranged vertically. The hollow support shaft is placed horizontally on the upper mixing cylinder 2, while the second rotating shaft is placed vertically inside the lower slurry mixing cylinder 3. The two shafts are arranged vertically.

[0042] like Figure 3 and Figure 4 As shown, the upper mixing cylinder 2 includes an upper cylinder body 21 and a mixing cylinder 22. The mixing cylinder 22 is mounted inside the upper cylinder body 21 via a feeding and stirring device 23. A feed pipe is opened on the top surface of the upper cylinder body 21, and the feed pipe is connected to the mixing cylinder 22 through a feeding hopper 5. The mixing cylinder 22 is a hollow cylinder with a feeding port on its side. The end of the feeding hopper 5 is arc-shaped and adapted to the mixing cylinder 22. The inside of the feeding hopper 5 is connected to the feeding port of the mixing cylinder 22. The raw material enters through the feed pipe and slides into the mixing cylinder 22 through the feeding hopper 5. The mixing cylinder 22 rotates and feeds materials inside the upper cylinder body 21.

[0043] like Figure 2 and Figure 5 As shown, the feeding and mixing device 23 also includes a second motor 233 and a first mixing fan 234. The first motor 231 drives a gear connected to one end of the feeding rotating component 232, which is rotatably mounted on the upper cylinder 21. The other end of the feeding rotating component 232 is fixedly connected to the mixing cylinder 22. The second motor 233 is connected to the first mixing fan 234 via a first rotating shaft. The feeding rotating component 232 is constructed from a gear transmission component and a hollow support shaft. The hollow support shaft passes through the upper cylinder 21 and has a bearing at its connection with the upper cylinder 21 to reduce friction between the hollow support shaft and the upper cylinder 21, allowing the hollow support shaft to rotate smoothly. It also provides support and positioning, ensuring the stability of the feeding rotating component 232 during rotation. The mixing cylinder 22 is mounted on one end of the hollow support shaft inside the upper cylinder 21. The mixing cylinder 22 can rotate synchronously with the feeding rotating component 232 to achieve material feeding. A gear transmission component is provided at the outer end. The second motor 233 is fixedly mounted on the upper cylinder 21 via a mounting bracket. On one side of the cylinder 21, the second motor 233 is mounted on the side of the upper cylinder 21, directly opposite the center of the hollow support shaft. The first rotating shaft passes through the feeding rotating component 232 and is connected to the first stirring fan 234. The first stirring fan 234 is located inside the mixing cylinder 22. The first rotating shaft passes through the inside of the hollow support shaft. The second motor 233 drives the first stirring fan 234 to stir and mix inside the mixing cylinder 22. Because the inlet of the mixing cylinder 22 is connected to the feed hopper 5 when the mixing cylinder 22 moves, it can effectively avoid the first stirring fan 234. 34. During the mixing process, the splashing of raw materials is prevented by the independent operation of the first motor 231 and the second motor 233. When the second motor 233 starts, it drives the first stirring fan 234 to rotate inside the mixing cylinder 22 via the first rotating shaft, which fully mixes the materials and improves their uniformity. The mixing cylinder 22 rotates synchronously with the rotating feeding component 232 to discharge the materials. At the same time, the first stirring fan 234 rotates inside the mixing cylinder 22 to sweep out the materials, greatly improving the discharge efficiency.

[0044] like Figure 4 As shown, the mounting bracket is preferably a stainless steel tripod.

[0045] like Figure 3 As shown, the inner cavity of the upper cylinder 21 below the mixing cylinder 22 is provided with a discharge slope, which is connected to the lower slurry mixing cylinder 3. The discharge slope is funnel-shaped, and the discharge port is connected to the inlet of the lower slurry mixing cylinder 3. Both the upper cylinder 21 and the mixing cylinder 22 are provided with observation windows.

[0046] like Figure 6As shown, the lower slurry mixing drum 3 includes a lower drum body 31, a third motor 32, several second mixing fans 33, and a distributing head 34. The lower drum body 31 is fixedly installed on the upper surface of the mounting plate of the support frame 1. The third motor 32 is located on the lower surface of the mounting plate of the support frame 1. The third motor 32 is connected to several second mixing fans 33 through a second rotating shaft. A distributing head 34 is installed at the end of the second rotating shaft. The distributing head 34 is directly opposite the outlet of the upper mixing drum 2 to disperse the mixed material, so that the material is more evenly distributed in the lower drum body 31. The evenly dispersed material can make the various components blend faster and reduce the product quality difference caused by uneven mixing. The number of second mixing fans 33 is preferably two. The second mixing fan 33 near the lower drum body 31 is shaped like a fan and is adapted to the shape of the bottom of the lower drum body 31. It pushes and scrapes the bottom slurry, avoiding the accumulation and clumping of slurry at the bottom of the lower drum body 31, and ensuring that the bottom slurry can also fully participate in the mixing process.

[0047] like Figure 6 As shown, a liquid level sensor 6 and a temperature sensor 7 are installed inside the lower cylinder 31. The temperature sensor 7 and the liquid level sensor 6 are arranged opposite each other, with the temperature sensor 7 slightly higher than the liquid level sensor 6 to avoid damage to the temperature sensor 7 by the slurry. This effectively prevents the slurry from directly contacting the temperature sensor 7. Both the temperature sensor 7 and the liquid level sensor 6 are communicatively connected to the controller 8. The liquid level sensor 6 and the temperature sensor 7 can timely and accurately sense changes in the liquid level and the temperature range inside the cylinder, providing accurate liquid level and temperature information for the operation control of the equipment, and timely shutting off the heating plate 44 or stopping the feeding. The first motor 231, the second motor 233, the third motor 32, the linear driver 41, and the heating plate 44 are all communicatively connected to the controller 8.

[0048] like Figure 7As shown, the heating support 4 includes several linear actuators 41, a support cover 42, several damping spring columns 43, and several heating plates 44. The linear actuators 41 are mounted on the support frame 1. The convex side of the support cover 42 is connected to the telescopic ends of the linear actuators 41. The concave side of the support cover 42 is provided with several heating plates 44 and several damping spring columns 43. The linear actuators 41 are preferably servo electric cylinders, and preferably two in number, which are simultaneously controlled by the controller 8 to provide stable support for the support cover 42, avoiding instability problems that may occur due to single-point support, and making the entire heating support structure more stable. For added reliability, the shock-absorbing spring columns 43 and heating plates 44 are arrayed on the support cover 42. The support cover 42, which is positioned opposite to each other, covers the surface of the lower cylinder 31, conforms to the shape of the lower cylinder 31, increases the contact area with the lower cylinder 31, and improves the heat transfer efficiency. When the lower cylinder 31 shakes, the shock-absorbing spring columns 43 in the support cover 42 dampen the vibration. When the lower cylinder 31 shakes due to stirring, feeding, or other operations, the shock-absorbing spring columns 43 in the support cover 42 can play a timely role, absorbing and buffering the vibration energy to reduce the impact of vibration on the lower cylinder 31 and the entire heating support structure.

[0049] Working principle: The staff introduces raw materials and auxiliary materials, which slide into the mixing cylinder 22 through the feeding hopper 5. The controller 8 then starts the second motor 233, which drives the first stirring fan 234 to rotate inside the mixing cylinder 22 to fully mix the materials. At this time, the staff observes the mixing situation through the observation window. The first motor 231 is then started to drive the feeding rotating part 232 to rotate, which drives the mixing cylinder 22 to rotate synchronously, thus realizing the feeding of materials.

[0050] At the same time, the first stirring fan 234 rotates inside the mixing cylinder 22, sweeping out the material;

[0051] After the mixed material enters the lower slurry mixing drum 3, the material distribution head 34 disperses the material entering the lower drum 31. At the same time, the heating support 4 covers the lower slurry mixing drum 3. At this time, the shock-absorbing spring column 43 abuts against the lower drum 31 to dampen it. The heating plate 44 is then activated to uniformly heat and melt the slurry in the lower slurry mixing drum 3.

[0052] The third motor 32 is started to drive the second stirring fan 33 to stir the material in the lower cylinder 31. The liquid level sensor 6 and the temperature sensor 7 sense the changes in the liquid level and the temperature range in the cylinder and feed the information back to the controller 8. When the liquid level or temperature exceeds the set range, the controller 8 can take corresponding measures in time, such as turning off the heating plate 44 or stopping the feeding.
