[0001] The utility model relates to the technical field of capsule filling, in particular to a feeding mechanism of a capsule filling device and a filling device thereof. Background Art

[0002] In the production and manufacturing of capsules, processes such as batching, granulation, drying, mixing, packaging, and outsourcing are generally required. In the packaging of capsules, capsule filling devices are widely used, and capsule filling devices can efficiently fill capsules into capsule bottles. Compared with the traditional manual filling method, the use of capsule filling devices can greatly improve production efficiency and save human resources. Secondly, the capsule filling device has a high degree of accuracy. It can ensure that the dosage of the drug filled in each capsule is accurate, which helps to improve the efficacy and safety of the drug. In addition, the capsule filling device can also reduce human errors and avoid problems caused by inaccurate manual filling.

[0003] A bottle capsule filling machine is disclosed in the patent "Bottle Capsule Filling Machine" (publication number CN207403958U, hereinafter referred to as prior art 1). Prior art 1 is realized by a feeding mechanism, a bottle cap feeding mechanism, a capsule feeding mechanism and a filling platform. The bottle feeding mechanism includes a receiving mechanism and a conveying track. The receiving mechanism has an input and an output track, both of which extend downwardly, and the output track connects to the conveying track. The bottle cap feeding mechanism screens the bottle caps with outer edges, and includes a material tray, a lifting mechanism and an output track. The material tray has a collecting trough, and the lifting mechanism includes a belt conveyor track and a baffle. The transmission belt is provided with an inverted buckle, and the output track is connected to the baffle for bottle cap output. By rotating the bottle body slot on the bracket, the bottle body, the capsule, and the bottle cap feeding mechanism are passed in turn to achieve automated integration.

[0004] The capsule feeding mechanism in the prior art 1 is in the shape of a disk. By setting a rotating lever inside the capsule feeding mechanism, the capsule inside the capsule feeding mechanism is moved to the position of the discharge port, so that the capsule feeding is completed. However, the distance required for the lever in the prior art 1 to rotate one circle is long. When the lever is not moved by the lever, it is difficult to complete the autonomous feeding. When the lever in the prior art 1 is moved in circles, a certain interval time is required, and the continuous feeding process cannot be completed, which affects the production efficiency. In addition, the capsules in the capsule feeding mechanism in the prior art 1 may be blocked when entering the feeding pipe. Utility Model Content

[0034] Embodiment 1

[0035] Please refer to Figure 1 , the feeding mechanism of a capsule filling device provided by the embodiment of the present utility model includes a storage bin 100 and a vibration mechanism. In current technical applications, when a capsule filling device performs capsule filling operations, problems such as blockages caused by improper capsule conveyance often occur, which not only affects the smooth progress of the filling operation but also reduces the working efficiency of the entire capsule filling device.

[0036] To solve this problem, the present utility model proposes a solution, that is, a vibration mechanism is added to the storage bin 100 of the capsules. In this way, during the feeding process of the capsules, the vibration mechanism can simultaneously perform stirring and feeding, thereby realizing the auxiliary feeding effect on the capsules and effectively avoiding the problem of capsule blockage.

[0037] This design of feeding and stirring simultaneously keeps the capsules active throughout the process, thus greatly reducing the risk of jamming and clogging caused by long-term static placement of the capsules. In this way, the feeding mechanism of the capsule filling device can not only improve the efficiency of the filling operation but also ensure the smooth progress of the filling operation, thereby enhancing the practicality and reliability of the entire capsule filling device.

[0038] Please refer to Figure 2 , the vibration mechanism drives the storage bin 100 to vibrate. By driving the storage bin 100 to vibrate, the capsules inside it also vibrate accordingly. At the same time, when no feeding is taking place, the capsules are stored inside. When feeding is required, they leak downward under the action of gravity. When there may be a problem of blockage, vibration is used to solve this problem, enabling the leakage of materials to proceed smoothly.

[0039] Please refer to Figure 1 , a feeding tube 110 is connected to the bottom of the storage bin 100. The design of this feeding tube 110 is aimed at effectively assisting the smooth operation of the storage bin 100 during the discharging process. When the storage bin 100 needs to output materials, the feeding tube 110 plays its key role. Further, in order to ensure that the materials can be evenly and efficiently extracted from the storage bin 100, the feeding shaft of the vibration mechanism is extended deep into the feeding tube 110. This vibration mechanism conducts the discharging operation through the feeding tube 110. It can not only ensure the fluidity of the materials during the discharging process but also prevent the materials from being blocked or adhered during transportation, thus greatly improving the efficiency and quality of the discharging operation. During the entire process, the coordinated work between the feeding tube 110 and the vibration mechanism ensures that the materials can be evenly and continuously conveyed, which is crucial for maintaining the continuous and stable operation of the filling line.

[0040] Please refer to Figure 1 , a top cover 120 is provided at the top of the storage bin 100, and a bottom cover 111 is provided at the bottom of the feeding tube 110. The structure of the storage bin 100 provided by the present utility model has a detachable top cover 120 designed at the top, and the feeding tube 110 at the bottom is also equipped with a detachable bottom cover 111. Such a design ensures the complete closure of the internal spaces of the storage bin 100 and the feeding tube 110, which not only guarantees the safety of the materials during storage and transportation but also prevents the intrusion of external pollution. When it is necessary to increase the storage capacity, the operator can easily open the top cover 120 and then conveniently add capsules into the bin.

[0041] However, the traditional way of directly opening the top cover 120 for material addition often needs to be carried out after the machine stops running, which undoubtedly reduces the efficiency of the filling operation. To solve this problem, a feeding port is further proposed to be set at the top of the storage bin 100. Through this setting, the operator can add materials through the feeding port when the machine is running continuously, thus greatly improving the continuity and efficiency of the filling operation. This improvement not only ensures the efficiency of the device in the filling operation, but also reduces the production delays that may occur due to stopping the machine to add materials, thereby improving the overall production efficiency. By setting a feeding port at the top of the storage bin 100, material addition can be achieved without stopping the machine, improving the operation convenience and production efficiency of the equipment.

[0042] Please refer to Figure 1 , the vibration mechanism includes a vibration motor 230 and a feeding shaft, and the feeding shaft is a spiral shaft 210. In the vibration operation, it is difficult for the smooth feeding shaft to assist in guiding and transporting the internal capsules. Therefore, the spiral shaft 210 is adopted, and spiral thread pieces are arranged on the feeding shaft. By rotating, the capsules can be driven to move, thus avoiding the possible blockage of the capsules during transportation.

[0043] The vibration mechanism is mainly composed of a vibration motor 230 and a feeding shaft, and the feeding shaft adopts a spiral shape design. This setting enables the feeding shaft to more effectively drive and guide the internal capsules during the stirring process. Due to structural limitations, the traditional feeding shaft is difficult to comprehensively guide and transport the inside of the capsules, which to a certain extent affects the stirring effect and transportation efficiency. After adopting the spiral shaft 210, this problem is effectively solved. Specifically, a group of spiral thread pieces are arranged on the feeding shaft. Under the vibration of the feeding shaft, these thread pieces can transport the materials inside the capsules. First, they fall under the action of gravity, and then they fall through vibration, and at the same time guide the capsules to be transported axially. In this way, not only the transportation efficiency is improved, but also the possible blockage problem of the capsules during transportation is avoided.

[0044] In addition, the design of the feeding shaft also considers the connection method with the storage bin 100 and the feeding cylinder 110. The feeding shaft extends from the top of the storage bin 100 to the bottom of the feeding cylinder 110, so that the feeding shaft can fully contact the materials in the storage bin 100, ensuring the correct guiding of the material transportation route.

[0045] Please refer to Figure 1 , the feeding shaft is arranged between the storage bin 100 and the feeding cylinder 110, so that the capsules accumulated in the storage bin 100 and the feeding cylinder 110 can be driven, and the capsules will not be blocked within the overall transportation range.

[0046] The vibration of the feed shaft in the present utility model between the storage bin 100 and the feed cylinder 110 has an active coverage area that is not limited to the internal space of the storage bin 100, but also includes the internal space of the feed cylinder 110. With this arrangement, the feed shaft can achieve comprehensive vibration and guidance of the capsules in the storage bin 100 and the feed cylinder 110, ensuring the smoothness of the capsules along the entire conveying path and effectively avoiding the problem of capsule blockage during transportation. This setting of the vibration range ensures that the capsules can be evenly driven, enabling all capsules to be fully driven and conveyed, thereby improving the conveying efficiency and ensuring the integrity and quality of the capsules during transportation. At the same time, this arrangement also improves the reliability of the equipment and reduces the difficulty and frequency of maintenance.

[0047] Please refer to Figure 1 and Figure 2 , an opening is provided on the body of the feed cylinder 110, and this opening is the discharge port 112. The function of this discharge port 112 is to allow the capsules to be smoothly sent out from the feed cylinder 110. The specific position of the discharge port 112 is at the bottom of the feed cylinder 110. At the upper end of the feed cylinder 110, an opening is provided, which also serves as the feed port for the capsules. The capsules are stored in the storage bin 100 through this feed port.

[0048] The inner diameter of the feed cylinder 110 is larger than the major diameter of the thread on the spiral shaft 210; a feed channel is formed between the spiral shaft 210 and the inner wall of the feed cylinder 110. This setting is to allow the material to smoothly enter the feed cylinder 110 and avoid friction between the spiral shaft 210 and the inner wall of the feed cylinder 110. During the rotation of the spiral shaft 210, the material will be driven to move axially, thus forming an effective feed channel. The smoothness of this channel directly affects the feed efficiency of the material and the overall working performance of the equipment, ensuring the stability and uniformity of the material during transportation, thereby improving the efficiency of the entire production process and the product quality.

[0049] Furthermore, please refer to Figure 5, a first conveying mechanism 800 is also provided, and the first conveying mechanism 800 is a belt conveying mechanism. The first conveying mechanism 800 is provided with first limiting plates 810 on both sides respectively, and a pair of guiding plates 820 are also arranged on the inner side of the first conveying mechanism 800. The pair of guiding plates 820 are distributed on the belt of the belt conveying mechanism. The guiding plates 820 are made of rubber products and can be bent or straightened together with the belt for repeated feeding. The capsules conveyed out from the storage bin 100 fall onto the first conveying mechanism 800 and are conveyed by the belt of the first conveying mechanism 800. In order to prevent the falling position of the capsules from exceeding the position of the first conveying mechanism 800, the first limiting plates 810 are provided to limit the position of the capsules on the first conveying mechanism 800. The guiding plates 820 facilitate the subsequent mechanism to be connected to the first conveying mechanism 800, so that the conveying path and position of the capsules are fixed and can be accurately conveyed to the preset position.

[0050] Preferably, a first mounting seat 113 and a second mounting seat 121 are respectively provided on the top cover 120 and the bottom cover 111; both ends of the spiral shaft 210 are fixed based on the first mounting seat 113 and the second mounting seat 121 respectively.

[0051] Furthermore, at the positions of the top cover 120 and the bottom cover 111, a first fixing seat 121 and a second fixing seat 113 are provided. The main function of these fixing seats is to provide stable support for the spiral shaft 210. Both ends of the spiral shaft 210 can be fixed relying on these two fixing seats. Such a setting ensures the stability of the feeding shaft and also makes the whole vibration process smoother.

[0052] Please refer to Figure 1 , a vibration motor 230 is installed on the top of the storage bin 100, which is the core power source of the whole equipment. The vibration motor 230 will drive the storage bin 100 to vibrate, so that the capsules inside the storage bin 100 vibrate and make the feeding smoother. The work of the vibration motor 230 is converted into the vibration force on the capsules, so that the capsules can move smoothly driven by the spiral shaft 210 and avoid capsule blockage.

[0053] Please refer to Figure 1 and Figure 5, the guiding plates 820 on both sides of the first conveying mechanism 800 are arranged in an arc shape, with a large opening at the top and a small opening at the bottom. One end with a small opening of each pair of guiding plates 820 is the discharging end, and the guiding plates 820 are made of rubber. The width of the end with a larger opening of the guiding plates 820 on both sides of the first conveying mechanism 800 is the same as the width of the first limiting plates 810 on both sides of the first conveying mechanism 800. The vibration motor 230 drives the storage bin 100 to vibrate, so that the capsules are fed through the feeding channel, shaken onto the conveyor belt of the first conveying mechanism 800, and the positions of the capsules are restricted by several pairs of guiding plates 820 arranged on the conveyor belt. Through the setting of the feeding end of the guiding plates 820, the capsules slide from the top to the bottom of the guiding plates, and the capsules will not be blocked, so that the capsules enter the expected feeding port 312; the capsules are fed through the feeding port 312. So that the capsules can complete the filling operation with the capsule bottles.

[0054] In a second aspect, please refer to Figure 1 and Figure 3 , a filling device is provided, including the feeding mechanism of a capsule filling device as described above; the feeding mechanism is connected to the filling device. The first conveying mechanism 800 conveys the capsules to a preset position, and then the capsules fall, and are directly conveyed to the expected filling position through an inclined receiving box 314 and a connecting pipe 313 under the receiving box 314.

[0055] The filling device includes a feeding mechanism of a capsule filling device, which is a key part of the whole device and is responsible for accurately conveying the material to be filled to the filling position. The feeding mechanism is connected to the filling device through a mechanical structure to ensure the stability and safety of the material during transmission. It can be adjusted according to needs to adapt to different specifications and types of capsules, so that the filling device has a wider application range and higher flexibility.

[0056] The filling device further includes a conveying mechanism and a filling mechanism; the filling mechanism is arranged on the top of the conveying mechanism. The conveying mechanism is used to convey the empty bottles ready to load the capsules, convey the empty bottles to the position of the filling mechanism, and perform the filling operation.

[0057] The filling mechanism includes multiple filling cylinders 310; when each filling cylinder 310 is loaded, it is aligned with the mouth of the corresponding empty bottle and loaded. During loading, the empty bottle is sent to the position corresponding to the filling cylinder 310 by the conveying mechanism and stops. After alignment, the conveying structure stops working. After loading is completed, it moves again, and the filled capsule bottle 500 is sealed to complete the operation. The filling cylinder 310 is only an auxiliary feeding device, and the capsules are not stored inside it. It only combines with the capsule bottle to enable smooth feeding without clogging problems. Please refer to Figure 4 , the feeding mechanisms of the filling device are connected through a connecting pipe 313; the connecting pipe 313 is a folding pipe and can be telescoped with the filling device when the filling device is telescoped.

[0058] Please refer to Figure 3 , the conveying mechanism includes a frame, a positioning plate, a conveying belt 420 and rollers 430; the positioning plate includes a first sub-positioning plate 411 and a second sub-positioning plate 412. The first sub-positioning plate 411 and the second sub-positioning plate 412 are respectively arranged on both sides of the frame to limit and protect the position where the capsule bottle 500 is conveyed or loaded. So that the capsule bottle 500 can be restricted and protected in position during operation. When the capsules are loaded, the capsule bottle 500 will vibrate to a certain extent. Through the position limitation of the positioning plate, no matter how large the vibration of the capsule bottle 500 is, it cannot fall off.

[0059] The rollers 430 include at least two pairs, which are respectively arranged at both ends of the positioning plate and fixed by the positioning plate. The conveying belt 420 is sleeved on at least two rollers 430, and the rotation of the rollers 430 drives the belt, so that the capsule bottle 500 can move.

[0060] Please refer to Figure 3 , the conveying belt 420 is sleeved on two pairs of the rollers 430; several capsule bottles 500 are conveyed through the conveying belt 420, and one filling cylinder 310 corresponds to one capsule bottle 500; the diameter of the filling nozzle 311 of the filling cylinder 310 is smaller than the diameter of the mouth of the capsule bottle 500.

[0061] The conveyor belt 420 is installed around two sets of rollers 430; through the conveyor belt 420, a number of capsule bottles 500 are transported to the designated position, and each capsule bottle 500 corresponds to a filling cylinder 310. There is an outlet for outputting capsules on this filling cylinder 310, and its diameter is smaller than the opening diameter of the capsule bottle 500. Such a setting allows the filling cylinder 310 to be closely sleeved on the capsule bottle 500, ensuring that the capsule bottle 500 can be filled evenly and stably during the drug filling process. In addition, since the diameter of the filling nozzle 311 is smaller than the bottle mouth diameter of the capsule bottle 500, this also helps to prevent drug leakage during the filling process, improving the filling accuracy and efficiency.

[0062] Preferably, a plurality of the filling cylinders 310 are installed through the same mounting frame 600; the mounting frame 600 is installed on the lifting mechanism.

[0063] Please refer to Figure 3 , a plurality of specified filling pipes adopt a common installation method, that is, they are assembled through a special mounting frame 600; this mounting frame 600 itself is also fixedly installed on the lifting mechanism. This lifting mechanism has the function of moving up and down, providing a vertical movement option for the mounting frame 600 and the pipes. When it is necessary to adjust or repair these pipes, or when it is necessary to work close to or away from the bottle mouth of the capsule bottle 500, the mounting frame 600 can move up and down with the help of the lifting mechanism, so that the staff can operate conveniently.

[0064] The lifting mechanism includes a support rod 710 and a cylinder 720; the piston rod of the cylinder 720 is fixedly connected to the top plate 610 of the mounting frame 600; the cylinder 720 is arranged at the top of the support rod 710 and fixed to the support rod 710. In this mechanism, the piston rod of the cylinder 720 is closely connected to the top plate 610 of the mounting frame 600, ensuring the stability of the lifting. The cylinder 720 is installed at the top of the support rod 710 and firmly fixed to the support rod 710 by a fixing device to withstand various forces generated during the lifting process.

[0065] The mounting frame 600 is further provided with a connecting plate 620; both ends of the connecting plate 620 are the top plate 610 and the lifting slider 630; both the top plate 610 and the lifting slider 630 are sleeved on the support rod 710. The top plate 610 and the lifting slider 630 are both sleeved on the support rod 710, and through cooperation with the cylinder 720, the lifting action is realized.

[0066] Please refer to Figure 1 and Figure 3, a feed inlet 312 connected to the feeding mechanism is provided at the top of each filling cylinder 310. A plurality of the filling cylinders 310 are operated by a lifting mechanism to approach or move away from the mouth of the capsule bottle 500. The filling cylinder 310 is an important part of the lifting mechanism, and a feed inlet 312 connected to the feeding mechanism is provided at its top. The function of this feed inlet 312 is to facilitate the entry of materials to achieve the filling of the capsule bottle 500. Through the operation of the lifting mechanism, a plurality of filling cylinders 310 can be operated to approach or move away from the mouth of the capsule bottle 500 to complete the filling task. This lifting mechanism realizes the automatic filling of the capsule bottle 500 through the coordinated work of a cylinder 720, a support rod 710, a connecting plate 620, a top plate 610, a lifting slider 630 and the filling cylinder 310, improves the production efficiency and reduces the labor cost.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
