Abstract
Description
Technical Field
[0001] This invention relates to the field of capsule testing technology, and in particular to a capsule feeding device. Background Technology
[0002] The capsule shell consists of a capsule body and a capsule cap. The capsule body is a hollow cylindrical shape with a slightly longer axial length and a spherical cap, while the capsule cap is a hollow cylindrical shape with a slightly larger diameter and a spherical cap. The capsule body and capsule cap are tightly fitted together and nested within each other by their respective cylinders. An empty capsule is a capsule without medication; in this state, the cylinders of the capsule body and capsule cap overlap less, meaning it is in a weakly locked state. A capsule filled with medication is a capsule with more overlap in the cylinders of the capsule body and capsule cap, meaning it is in a fully locked state. Both empty capsules and capsules filled with medication are collectively referred to as capsules.
[0003] The total length of the capsule is the sum of the total length of the two cylinders after they are fitted together and the radii of the spherical caps at both ends. The capsule consists of two fitted cylinders, a spherical cap for the capsule body, and a spherical cap for the capsule cap. The length of the cylinder is equal to the total length of the two cylinders after they are fitted together, and the diameter of the cylinder of the capsule cap is the diameter of the capsule.
[0004] The demand for capsule-by-capsule testing of indicators such as shape, color, dosage variation, and metal content is increasing. Before capsule-by-capsule testing, it is necessary to dispense capsules one by one in an orderly manner, whether in bulk, piles, bags, or barrels. This requires a capsule-by-capsule dispensing device. Current capsule dispensing devices mainly use multi-stage vibrating V-groove corrugated plates with a number of channels corresponding to the number of channels in the testing equipment under the hopper. The first-stage corrugated plate disperses the capsules into different V-grooves, and subsequent corrugated plates disperse the capsules in the V-grooves one by one in a queue. However, this method cannot control the rapid and evenly spaced removal of capsules from the corrugated plates, easily leading to inconsistent spacing between adjacent capsules in the same V-groove. When the spacing between adjacent capsules is large, the testing efficiency is greatly reduced. When the spacing between adjacent capsules is small, more than two capsules may enter the testing device simultaneously, causing testing failure and also resulting in low testing efficiency.
[0005] Therefore, how to effectively improve the efficiency of capsule detection is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0006] In view of this, the purpose of the present invention is to provide a capsule toothing and feeding device that can effectively improve capsule detection efficiency.

[0027] Preferably, the groove includes a groove center surface located between the two sidewalls, and the groove center surface is located at a position 20°-50° counterclockwise from the midpoint between the center point of the gear plate and the bottom of the groove.
[0028] Preferably, the distance between the guard plates on both sides of any one of the toothed discs is greater than the diameter of the capsule.
[0029] Preferably, it further includes two guide rails respectively disposed between the toothed disc and the guard plates on both sides, the two guide rails being symmetrical about the toothed disc and parallel to each other, the guide rails being used to support the capsule.
[0030] Preferably, the guide rail includes a first guide rail and a second guide rail that is connected to the first guide rail. The first guide rail is located near the lower part of the outlet end of the capsule conveying channel, and the first guide rail and the second guide rail have the same structure.

[0043] Compared with existing technologies, since the teeth are evenly distributed around the circumference of the tooth disc body and the shape of multiple teeth is the same, the grooves formed between any two adjacent teeth are the same in shape and the spacing between any two adjacent grooves is also equal.
[0044] With this configuration, when the rotating shaft drives the toothed disc to rotate at a constant speed, the time intervals between capsules falling sequentially from the capsule conveying mechanism into the grooves on the toothed disc are equal, and the time intervals between capsules exiting the grooves on the toothed disc are also equal. Therefore, the capsule toothed feeding device disclosed in this embodiment of the invention will not exhibit excessively large or small spacing between adjacent capsules during operation. By controlling the speed of the driving mechanism, the exit speed of adjacent capsules is controllable, and the time interval between them entering the detection device is controllable. Thus, the feeding speed can be greatly improved, thereby further improving the capsule detection efficiency. Attached Figure Description

[0063] In view of this, the core of the present invention is to provide a capsule toothing and feeding device, which can effectively improve the capsule detection efficiency.
[0064] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to... Figures 1 to 15 .
[0065] Please refer to Figure 1 , Figure 2 and Figure 9 The capsule feeding device disclosed in this embodiment of the invention includes a capsule conveying mechanism 100 and a feeding disc 200, wherein the capsule conveying mechanism 100 is provided with a capsule conveying channel 103 for conveying capsules 300.
[0066] Among them, at least one toothed disc 200 is provided, and the capsule conveying channel 103 is provided in a one-to-one correspondence with the toothed disc 200, and the toothed disc 200 is provided at the lower outlet end of the capsule conveying channel 103.
[0067] Specifically, the paddle shifter 200 includes a paddle shifter body 201 and a plurality of paddle teeth 202 of the same shape evenly distributed along the circumference of the paddle shifter body 201, and a groove 203 is formed between any two adjacent paddle teeth 202. The paddle shifter body 201 has a paddle shifter center point 2035.
[0068] Each toothed disc 200 has a guard plate 502 on both sides. The toothed disc 200 can rotate. The capsule conveying mechanism 100 can convey the capsule 300 into the groove 203 between the two guard plates 503 during the rotation of the toothed disc 200. The capsule 300 is then output to the detection device through the rotation of the groove 203.
[0069] Compared with the prior art, since the teeth 202 are evenly distributed along the circumference of the tooth disc body 201 and the shape of multiple teeth 202 is the same, the grooves 203 formed between any two adjacent teeth 202 are the same in shape and the spacing between any two adjacent grooves 203 is also equal.
[0070] With this configuration, the capsules 300 enter the grooves 203 on the toothed disc 200 from the capsule conveying mechanism 100 at equal times, and the time interval between the capsules 300 being ejected from the grooves 203 is also equal. Therefore, during operation, the capsule toothed feeding device disclosed in this embodiment of the invention will not exhibit excessively large or small spacing between adjacent capsules 300. The distance between adjacent capsules 300 is controllable, and the time for them to enter the detection device is controllable, thus greatly improving the feeding speed and further enhancing the capsule detection efficiency.
[0071] The embodiments of the present invention do not limit the specific structure of the capsule delivery mechanism 100. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.
[0072] The capsule conveying mechanism 100 can be a rectangular capsule conveying body, which is vertically arranged along its length and has a channel for the capsule 300 to pass through. Of course, the capsule conveying mechanism 100 can also be a curved pipe or a spring pipe or other structures that allow the capsule to pass through.
[0073] As a preferred embodiment, see Figure 2 The capsule delivery mechanism 100 disclosed in this embodiment of the invention includes a capsule delivery body 101 and a cover 102, wherein the cover 102 and the capsule delivery body 101 can be engaged.
[0074] Among them, see Figure 9 The capsule delivery body 101 has at least one groove 1011, and the cover 102 is fastened to the groove 1011 to form a capsule delivery channel 103 for the capsule 300 to pass through.
[0075] It should be noted that the capsule conveying mechanism 100 is configured into two parts: the capsule conveying body 101 and the cover 102, which makes it easy to disassemble and assemble, thereby facilitating the cleaning of the capsule conveying channel 103.
[0076] It should be further explained that in the capsule delivery mechanism 100 disclosed in this embodiment of the invention, the height of the lower edge of the cover 102 is higher than the height of the lower edge of the capsule delivery body 101. At this time, the lower edge of the cover 102 is also the notch edge of the outlet end of the capsule delivery channel 103, which will be mentioned later. Therefore, the outlet end of the capsule delivery channel 103 is located at the position formed by the bottom end face of the cover 102 and the groove 1011. This arrangement can further facilitate the setting of the toothed disc 200, and the capsule 300 will not slide counterclockwise.
[0077] As a preferred option, see Figure 2 and Figure 9 In the embodiments of the present invention, the capsule delivery body 101 and the cover 102 are preferably rectangular structures. The capsule delivery channel 103 is arranged along the length direction of the capsule delivery body 101 and the cover 102. Multiple capsules 300 are arranged in a row from top to bottom in the capsule delivery channel 103, waiting to enter the toothed disc 200.
[0078] The specific number of toothed discs 200 is not limited in the embodiments of the present invention. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.
[0079] As a preferred embodiment, the number of toothed discs 200 disclosed in this embodiment of the invention is at least one, wherein the number of toothed discs 200 is the same as the number of capsule conveying channels 103; specifically, the toothed discs 200 are set at the outlet end of the capsule conveying channel 103 to receive capsules 300.
[0080] Those skilled in the art will understand that the more toothed discs 200 are provided, the higher the dispensing efficiency of the capsule dispensing device disclosed in this embodiment of the invention. Therefore, those skilled in the art can select the specific number of toothed discs 200 according to actual needs.
[0081] In this embodiment of the invention, the number of toothed discs 200 is preferably set to three, and therefore, the capsule conveying channels 103 are also set to three accordingly.
[0082] In order to ensure that the capsule 300 can smoothly enter the groove 203, the width of the groove 203 disclosed in the embodiments of the present invention is preferably greater than the diameter of the capsule cap of the capsule 300.
[0083] To ensure the controllable posture of the capsule 300, the width of the groove 203 disclosed in this embodiment only needs to be slightly larger than the diameter of the capsule cap of the capsule 300. When the groove 203 is aligned with the outlet end of the capsule transport channel 103, the capsule 300 can be embedded in the groove 203. With this configuration, when the capsule 300 enters the groove 203 from the capsule transport channel 103, it can maintain a preset posture within the groove 203.
[0084] The lower edge of the capsule conveying channel 103 can be flush or have a notch on the lower edge, and the notch is located near the rotating discharge side of the toothed disc 200.
[0085] It should be noted that, see Figure 12 and Figure 15 Preferably, in this embodiment, the lower edge of the outlet end of the capsule conveying channel 103 is a notch edge. When the groove 203 is aligned with the outlet end of the capsule conveying channel 103, the distance between the bottom of the groove 203 and the notch edge of the outlet end of the capsule conveying channel 103 is greater than the length of the capsule 300. This arrangement ensures that when the capsule 300 falls into the groove 203 and rotates with the toothed disc 200, the top of the capsule 300 will not touch the bottom of the cover 102.
[0086] As a preferred embodiment, in the capsule feeding device disclosed in this embodiment of the invention, the depth of the groove 203 is preferably greater than the radius of the spherical cap of the capsule 300.
[0087] The trench 203 includes two sidewalls arranged opposite each other, and the heights of the two sidewalls may be the same or different.
[0088] See Figure 4When the two sidewalls are at different heights, the height of the sidewall with the lower height is equal to the depth of the groove 203. This design ensures that when the capsule 300 first falls into the groove 203, the cylindrical portion of the capsule 300 engages with both sidewalls of the groove 203, thus preventing the capsule 300 from tipping over.
[0089] It should be noted that the lower edge of the outlet end of the capsule conveying channel 103 can be flush. Of course, a notch can also be provided on the lower edge of the outlet end of the capsule conveying channel 103, and the notch is located near the center point 2035 of the toothed disc. Those skilled in the art can choose according to actual needs.
[0090] As a preferred embodiment, the capsule feeding device disclosed in this embodiment of the invention preferably has a notch on the lower edge of the outlet end of the capsule conveying channel 103.
[0091] See Figure 15 It should be noted that when the toothed disc 200 rotates clockwise, when the toothed disc 202 is placed at the outlet end of the capsule conveying channel 103, the distance from the edge A of the notch at the outlet end of the capsule conveying channel 103 to the top surface of the toothed disc 202 is less than the difference between the length of the capsule 300 and the radius of the spherical cap of the capsule 300, and is greater than the diameter of the spherical cap of the capsule 300. This avoids the top surface of the rotated toothed disc 202 from being squeezed, deformed, or damaged and leaking powder if the capsule 300 accidentally fails to fall into the groove 203.
[0092] Before the capsule enters the toothed disc 200 from the outlet end of the capsule conveying channel 103, it first stands upright on the top of the toothed disc 202. The above structure ensures that a small section of the capsule 300 remains within the capsule conveying channel 103 before falling into the groove 203. This ensures that the movement of the toothed disc 202 during rotation, start-up, or shutdown will not drag the capsule 300 standing on the toothed disc 202. When the equipment stops, the toothed disc 200 will not damage the capsule 300 or cause it to fall out of the capsule 300 uncontrollably, no matter what angle it stops at. When the equipment stops, the capsule 300 will either stand upright on the toothed disc 202 or fall into the groove 203.
[0093] The embodiments of the present invention do not limit the specific structure of the groove 203. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.
[0094] For a preferred embodiment of the present invention, please refer to the following: Figure 3 and Figure 4Any groove 203 disclosed in the embodiments of the present invention includes a long sloping surface 2031 and a short protective surface 2032, wherein the long sloping surface 2031 and the short protective surface 2032 are parallel to each other, and the height of the long sloping surface 2031 is greater than the height of the short protective surface 2032.
[0095] With this configuration, the longer actuating surface 2031 is higher, ensuring that when the actuating disc 200 rotates clockwise, the higher sidewall of the groove 203 pushes it, preventing the capsule 300 from easily tipping over counterclockwise. The shorter actuating surface 2032 is lower than the longer actuating surface 2031, ensuring that when the actuating disc 200 rotates, the movement of the tooth tip of the actuating tooth 202 causes the contact point between the tooth tip of the actuating tooth 202 and the bottom of the capsule 300 to continuously decrease in height relative to the ground. The friction between the tooth tip of the actuating tooth 202 and the bottom of the capsule 300 is greatly reduced or even zero. Before the groove 203 connects with the outlet end of the capsule conveying channel 103 with its opening facing upwards, the tooth tip of the actuating tooth 202 will not drag the capsule 300 standing in the capsule conveying channel 103 over, and the capsule 300 can only fall due to weightlessness.
[0096] The shorter protective surface 2032 is shorter than the longer protective surface 2031, which can cause the opening size of the groove 203 to be much larger than the width of the groove 203 when the opening of the groove 203 is facing upwards. As a result, the capsule 300 is more likely to fall into the groove 203.
[0097] Moreover, when the gear plate 200 rotates, when the capsule 300 falls vertically from the outlet end of the capsule conveying channel 103 into the groove 203, it can first contact the long gear surface 2031. When the groove 203 is completely aligned with the outlet end of the capsule conveying channel 103, half of the capsule 300 has already fallen into the groove 203. Therefore, the capsule 300 is more likely to slide completely into the groove 203, which is not only efficient but also less prone to jamming.
[0098] It should be noted that the bottom of the groove 203 is an arc-shaped structure that mimics the two ends of the capsule 300.
[0099] The connection between the long facet 2031 and the top surface of the tooth 202 is provided with a first rounded corner, and the connection between the short facet 2032 and the top surface of the tooth 202 is provided with a second rounded corner.
[0100] It should be noted that the height of the long protective surface 2031 disclosed in the embodiments of the present invention refers to the height when the first rounded corner is not provided, and the height of the short protective surface 2032 refers to the height when the second rounded corner is not provided.
[0101] It should be noted that the long facet 2031 includes the long facet vertex 2033, the short facet 2032 includes the short facet vertex 2034, and the main body of the shifter 201 includes the center point of the shifter 2035 (represented by O in the figure).
[0102] The radius of the circumcircle centered at the center point 2035 of the gear plate, where the vertex 2033 of the long gear face is located, is R1 (see attached diagram). Figure 4 As shown in the diagram, the radius of the outer circle centered on the center point of the gear plate 200, where the short guard vertex 2034 is located, is R2 (see attached diagram). Figure 4 As shown in the figure, R1 is greater than R2.
[0103] With this configuration, when the capsule 300 is in a near-weightless falling state as the toothed disc 200 rotates at high speed, the friction between the top of the toothed disc 202 and the bottom of the capsule 300 becomes smaller, making it less likely for the capsule 300 to be dragged over and allowing it to fall quickly into the groove 203.
[0104] It should be explained that the long facet vertex 2033 refers to the point located on the first rounded corner and farthest from the center point 2035 of the paddle shifter, while the short facet vertex 2034 refers to the point located on the second rounded corner and farthest from the center point 2035 of the paddle shifter.
[0105] It should be noted that the top surface of the pry bar 202 is a curved surface that smoothly transitions from the long pry bar vertex 2033 to the short guard vertex 2034.
[0106] It should be explained that the curve of the distance between each point on the top surface of the shifter 202 from R1 to R2 relative to the center of the shifter 200 and the rotation angle of the shifter 200 is a parabola.
[0107] The parabola is actually a curve of distance versus time. Different rotational speeds of the shaft 403 result in different times corresponding to a unit rotation angle of the toothed disc 200. For the already manufactured toothed disc 200, the parabola at the top of the tooth 202 can only achieve the weightless descent of the capsule 300 at a specific rotational speed. Therefore, to achieve weightlessness in the capsule 300, the rotational speed must be determined based on the target dispensing efficiency, and then the parabola must be designed. During the rotation of the toothed disc 200, the curve of the distance from the top of the tooth 202 to the cover 102 versus time or rotation angle is a parabola, allowing the capsule 300 to descend rapidly in a weightless and unobstructed state.
[0108] Please continue to refer to this. Figure 4 The trench 203 includes a trench center surface 2036 located between the two sidewalls (in the appendix). Figure 4 (represented by MM), wherein the center surface of the groove 2036 is located at a position 20°-50° counterclockwise from the midpoint between the center point 2035 of the gear plate and the bottom of the groove 203.
[0109] With this configuration, the groove 203 can receive the falling capsule 300 with the largest opening. The centrifugal force of the upper part of the capsule 300 in the radial direction during the rotation of the tooth 202 will also make the capsule 300 stuck at the short protective surface 2032 and less likely to fly out due to centrifugal force. Therefore, the above structure not only improves the feeding efficiency, but also greatly reduces the probability of the capsule 300 getting stuck.
[0110] The distance between the guard plates 502 on both sides of any one of the gear discs 200 is greater than the diameter of the capsule 300.
[0111] As a preferred embodiment, in the capsule feeding device disclosed in this embodiment of the invention, the distance between the guard plates 502 on both sides of any one of the toothed discs 200 is slightly larger than the diameter of the capsule 300. This facilitates the capsule 300 to be embedded in the groove 203 between the two guard plates 502, while preventing the capsule 300 from tilting at a large angle toward the guard plate 502, thus affecting the movement posture of the capsule 300 being agitated by the long toothed surface 2031.
[0112] See Figure 6 , Figure 7 and Figure 10 As a preferred embodiment, the capsule feeding device disclosed in this embodiment of the invention further includes two guide rails respectively disposed between the feeding disc 200 and the guard plates 502 on both sides. The two guide rails are symmetrical about the feeding disc 200 and parallel to each other, and the guide rails are used to support the capsules 300.
[0113] The embodiments of the present invention do not limit the specific structure of the guide rail. The guide rail can be a single guide rail or a combination of several guide rail segments. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.
[0114] As a preferred embodiment, the guide rail disclosed in this embodiment of the invention includes a first guide rail 503 and a second guide rail 504 that is connected to the first guide rail 503. The first guide rail 503 is located near the lower part of the outlet end of the capsule conveying channel 103, and the first guide rail 503 and the second guide rail 504 have the same structure.
[0115] As a further preferred embodiment, in the capsule feeding device disclosed in this embodiment of the invention, when the groove 203 is placed at the outlet end of the capsule conveying channel 103, the lowest point of the bottom of the groove 203 is tangent to the first guide rail 503.
[0116] See Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15In this process, from the moment the capsule 300 falls into the groove 203 from the capsule transport channel 103 until it is removed from the groove 203, it is always supported by the upper surfaces of the first guide rail 503 and the second guide rail 504. Therefore, the capsule 300 is both rotated clockwise by the toothed disc 200 and moved towards the detection device by the first guide rail 503 and the second guide rail 504 along the upper surfaces of the first guide rail 503 and the second guide rail 504.
[0117] The capsule 300 undergoes circular motion, centrifugal motion, and movement along the guide rail within the groove 203. Within the groove 203, the capsule 300 is consistently supported by the guide rails on both sides of the teeth 202. A side wall of the clockwise rotating groove 203 pushes the capsule 300 away from the groove 203 along the guide rail. The capsule 300 continues to slide away from the dispensing mechanism along the second guide rail 504 due to inertia and speed. The guide rails ensure that the entire process of the capsule 300 falling into the groove 203 from the outlet end of the capsule conveying channel 103 and exiting the groove 203 is controlled by the guide rails and the groove 203. It does not slide out due to its own weight when the groove 203 rotates below the horizontal plane, nor is it thrown out by centrifugal force generated by high rotation speed. The movement of the capsule 300 is completely controllable, and there is no problem of the capsule 300 getting stuck.
[0118] Because the short protective surface 2032 is very short, the capsule 300 is completely squeezed out of the groove 203 and enters the guide rail before it reaches the horizontal plane in the outlet direction of the groove 203. That is, the bracket action of the guide rail and the short size of the short protective surface 2032 cause the capsule 300 to leave the toothed disc 200 before the groove 203 reaches the horizontal plane, resulting in extremely short discharge time and extremely high efficiency.
[0119] As a further preferred embodiment, both the first guide rail 503 and the second guide rail 504 have an angle of 10°-40° with the horizontal plane, and the angle between the second guide rail 504 and the horizontal plane is greater than or equal to the angle between the first guide rail 503 and the horizontal plane. This arrangement can further reduce the probability of the capsule 300 being jammed by the side wall of the groove 203 during high-speed rotation.
[0120] On the other hand, the center surface 2036 of the groove is biased to the rear in the direction of rotation, so that the center surface 2036 of the groove is always at an obtuse angle with the first guide rail 503. During the rotation of the toothed disc 200, the side wall of the groove 203 is always pushing or pushing the capsule 300, which is located in the groove 203 and is supported on the opposing first guide rails 503 on both sides of the toothed disc 200, to the upper right. When the toothed disc 200 rotates, the long-push surface 2031 and the first guide rail surface 503 will not jam the capsule 300.
[0121] After any groove 203 rotates clockwise away from the outlet end of the capsule conveying channel 103, it intersects with the guide rail. As it rotates, more and more of the groove 203 is located below the guide rail, until the groove 203 is completely submerged below the guide rail.
[0122] It should be noted that the first guide rail 503 and the second guide rail 504 can both be curved surfaces or both be folded surfaces. This embodiment of the invention does not impose specific limitations on this.
[0123] In this embodiment of the invention, the width of the first guide rail 503 and the second guide rail 504 are not specifically limited, as long as the structure meets the usage requirements of this invention.
[0124] As a preferred embodiment of the present invention, the widths of the first guide rail 503 and the second guide rail 504 disclosed in the present invention are preferably the same.

[0126] The drive mechanism 400 includes a drive motor 401, a transmission belt 402 and a rotating shaft 403. The two ends of the transmission belt 402 are respectively connected to the drive motor 401 and the rotating shaft 403, and the gear plate 200 is disposed on the rotating shaft 403.
[0127] Start the drive motor 401, which drives the gear plate 200 to rotate via the transmission belt 402.
[0128] To facilitate the installation and setting of the gear shifting disc 200, the drive mechanism 400 disclosed in this embodiment of the invention further includes a bushing 404, wherein the gear shifting disc 200 is disposed on the bushing 404, and the bushing 404 is disposed on the rotating shaft 403.
[0129] To enhance the strength of the rotating shaft 403, the drive mechanism 400 disclosed in this embodiment of the invention further includes a first bearing 4031 and a second bearing 4032, which are used to support the rotating shaft 403.
[0130] For a preferred embodiment, please refer to Figures 5 to 7 The capsule feeding device disclosed in this embodiment of the invention also has brackets 500 on both sides of the feeding disc 200.
[0131] The bracket 500 includes a bracket body 501, a guard plate 502, and a guide rail. The guard plate 502 is disposed on the bracket body 501, and the guide rail is disposed on the guard plate 502.
[0132] The guide rail and guard plate 502 are both located on one side near the gear plate 200.
[0133] Specifically, bracket 500 is directly opposite rotating shaft 403, and bracket 500 and gear plate 200 are spaced apart.
[0134] To facilitate the installation and fixation of the bracket 500, the capsule feeding device disclosed in this embodiment of the invention also includes a bracket seat 600, on which the bracket 500 is mounted.
[0135] Specifically, the bracket base 600 includes a base plate 601, a back plate 602, a first side plate 603, and a second side plate 604, wherein the base plate 601, the back plate 602, the first side plate 603, and the second side plate 604 are connected to form an installation space for mounting the bracket 500.
[0136] To facilitate the installation of multiple brackets 500, the bracket base 600 also includes a partition 605 and a fixing rod 700. The number of partitions 605 is the same as the number of gear plates 200. There is at least one partition 605. The partition 605 is set in the installation space and divides the installation space into at least two independent sub-spaces. Each sub-space is embedded with a bracket 500.
[0137] The first side plate 603, the second side plate 604, the partition 605 and the bracket 500 are all provided with corresponding positioning through holes, and the fixing rod 700 can pass through the positioning through holes to fix the bracket 500 to the bracket seat 600.
[0138] The specific structure of the bracket 500 is not limited in the embodiments of the present invention. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.
[0139] It should be noted that in this embodiment of the invention, the guide rail is a platform structure protruding on the guard plate 502.
[0140] Please refer to Figures 8 to 15 When the capsule feeding device is working, please refer to... Figure 15 The capsule 300 stands on top of the paddle 202. The paddle 200 rotates rapidly. Because the curve of the distance between each point on the top surface of the paddle 202 from R1 to R2 relative to the center point 2035 of the paddle 200 and the rotation angle of the paddle 200 is a parabola, the capsule 300 loses all or part of its supporting force from the top of the paddle 202 and begins to fall towards the groove 203. Please refer to... Figure 14 When the groove 203 is directly opposite the outlet end of the capsule conveying channel 103, the capsule 300 falls rapidly into the groove 203; please refer to Figure 12 Within a very short time, capsule 300 completely falls into groove 203, at which point capsule 300 is in the first position (i.e., fully inside groove 203); please refer to Figure 11Capsule 300 is also supported by the first guide rail 503, and continues to rotate with the gear plate 200; please refer to Figure 15 The capsule 300 is pushed and slids on the first guide rail 503 by the rotating long dial 2031. After the dial 200 rotates by the angle occupied by one dial tooth 202 on the circumference of the dial 200; please refer to Figure 14 As capsule 300 moves from the first position to the second position, due to the shorter short protective surface 2032, capsule 300 begins to partially detach from groove 203 at the second position, resulting in extremely high feeding efficiency. At this point, the long actuating surface 2031 pushes the semi-erect capsule 300 to continue moving, simultaneously entering the second guide rail 504. Because the second guide rail 504 is more downwardly inclined than the first guide rail 503, the angle between the long actuating surface 2031 and the second guide rail 504 suddenly increases, significantly reducing the probability of the long actuating surface 2031 jamming the capsule 300 against the guide rail surface. The actuating tooth disc 200 continues to rotate. Please refer to... Figure 15 When capsule 300 is completely disengaged from the toothed disc 200, capsule 300 lies flat and slides along the second guide rail 504. The above process is the process of capsule 300 being completely ejected.
[0141] As the toothed disc 200 rotates continuously, each tooth 202 on the toothed disc 200 independently performs the above-mentioned feeding process, feeding out capsules 300 at high speed and continuously.
[0142] Actual test results show that, without capsule jamming, the capsule feeding device disclosed in this embodiment of the invention can feed 4.5 capsules per second per capsule conveying channel 103. Compared with the prior art, the feeding speed of the capsule feeding device disclosed in this embodiment of the invention is increased by 50%.
[0143] The capsule feeding device disclosed in this embodiment of the invention also includes a base 800 and a frame plate 900, wherein the capsule conveying mechanism 100 is fixedly connected to the frame plate 900.
[0144] The frame plate 900, bracket base 600, drive mechanism 400 and capsule conveying mechanism 100 are all mounted on the base 800.
[0145] This configuration facilitates the installation, disassembly, and cleaning of the frame upright plate 900, bracket base 600, drive mechanism 400, and capsule conveying mechanism 100.
