Abstract
Description
Technical Field
[0001] This utility model relates to the field of drug delivery, and more specifically, to a drug feeding mechanism. Background Technology
[0002] Vertical vibratory feeders, as a common type of automated feeding equipment, are widely used in industries such as electronics, food, and pharmaceuticals to transport materials to designated locations according to predetermined directions and speeds. Traditional vertical vibratory feeders typically employ horizontal or near-horizontal vibrating channels, relying on the attraction action of vibrating electromagnets to drive the material forward. However, this structure has the following drawbacks: 1. Low material conveying efficiency: Horizontal or near-horizontal vibrating channels cannot fully utilize gravity, limiting material conveying efficiency. This is especially true for materials with poor flowability, easily leading to problems such as poor conveying and blockages. Furthermore, when material flows from the vibrating channel into the feed head, it tends to accumulate inside the feed head, further exacerbating the blockage problem. 2. High equipment noise: Vertical vibratory feeders generate strong vibrations during operation. These vibrations are transmitted to the equipment frame and the ground through rigid connections, producing significant noise and affecting the working environment. Utility Model Content
[0003] The main objective of this invention is to provide a drug feeding mechanism to solve the problem of material blockage during the conveying process in the prior art.
[0004] To achieve the above objectives, according to one aspect of the present invention, a drug feeding mechanism is provided, including a feeding channel and a feeder, wherein the feeding channel is inclined; the feeder is connected to the outlet end of the feeding channel, the feeder has a feeding chamber, and the material is fed from the feeding channel through the feeding chamber; the outlet end of the feeding channel has a downwardly extending extension section, the end of which extends into the middle region of the feeding chamber.
[0005] Furthermore, the bottom of the feeding chamber has a discharge port, and the middle area is located in the area directly above the discharge port.
[0006] Furthermore, the central area and the area directly above the discharge port are arranged coaxially along the material conveying direction of the feeder.
[0007] Furthermore, along the material conveying direction, the extension section includes a first segment and a second segment that are bent and connected. The first segment is connected to the outlet end of the feeding channel, and the end of the second segment extends into the middle region. The acute angle formed by the first segment and the longitudinal direction is larger than the acute angle formed by the second segment and the longitudinal direction.
[0008] Furthermore, the extension direction of the first segment is set parallel to the material conveying direction of the feeding channel.
[0009] Furthermore, the drug feeding mechanism also includes a feeder, which is connected to a feeding channel drive. The feeder drives the feeding channel to vibrate in order to convey the material.
[0010] Furthermore, the drug feeding mechanism also includes a base and an elastic element, with the elastic element disposed between the feeder and the base.
[0011] Furthermore, the drug feeding mechanism also includes a first flexible component, which is disposed between the feeding channel and the feeder, and the feeding channel and the feeder are flexibly connected.
[0012] Furthermore, the drug feeding mechanism also includes a storage component and a second flexible component. The storage component is connected to the feeding channel, and the second flexible component is disposed between the storage component and the feeding channel, with a flexible connection between the storage component and the feeding channel.
[0013] Furthermore, the drug feeding mechanism also includes a weighing device, and the feeder has a discharge port, with the weighing device located below the discharge port.
[0014] By applying the technical solution of this utility model, the material flowability during the conveying process is improved by setting the feeding channel at an inclination and providing an extension section at the outlet end of the feeding channel, thereby avoiding blockage of the material during the conveying process. Specifically, on the one hand, the feeding channel is set at an inclination to assist the flow of the material with gravity, thereby improving the material flowability. On the other hand, the end of the extension section extends into the middle area of the feeding chamber, thereby ensuring that the material accurately enters the center position of the feeder and avoiding the accumulation of material on the inner wall of the feeding chamber, thereby further improving the material flowability, thereby improving the smoothness and efficiency of material conveying, and thus improving the drug dispensing efficiency.

[0027] To address the problem of material blockage during transport in existing technologies, this invention provides a drug feeding mechanism.
[0028] like Figures 1 to 6 The illustrated drug feeding mechanism includes a feeding channel 10 and a feeder 20. The feeding channel 10 is inclined. The feeder 20 is connected to the outlet end of the feeding channel 10 and has a feeding chamber. The material is fed from the feeding channel 10 through the feeding chamber. The outlet end of the feeding channel 10 has a downwardly extending extension section 11, the end of which extends into the middle region of the feeding chamber.
[0029] This embodiment improves the flowability of materials during conveying by tilting the feeding channel 10 and providing an extension section 11 at the outlet end of the feeding channel 10, thereby avoiding blockage. Specifically, on the one hand, tilting the feeding channel 10 allows gravity to assist the flow of materials, thus improving material flowability. On the other hand, the end of the extension section 11 extends into the middle area of the discharge chamber, ensuring that the materials accurately enter the center of the feeder 20, preventing material accumulation on the inner wall of the discharge chamber, thereby further improving material flowability, thus improving the smoothness and efficiency of material conveying, and ultimately improving drug dispensing efficiency.
[0030] It should be noted that the material in this embodiment refers to Chinese medicinal herbs, including slices, blocks, granules, powders, strips, flower-shaped, leaf-shaped, and fruit-shaped herbs, all of which can be conveyed by the drug feeding mechanism of this embodiment. Of course, the types of materials are not limited to these; depending on the actual situation, the drug feeding mechanism of this embodiment can also convey other materials. The central region in this embodiment refers to the area within the feeding chamber that is far from the inner wall of the feeder 20.
[0031] In this embodiment, the extension section 11 extends into the middle region of the feeder 20, meaning that the end of the extension section 11 that extends into the feeding chamber is suspended and does not contact the inner wall of the feeder 20, which is conducive to the rapid falling of materials.
[0032] In this embodiment, the bottom of the feeding chamber has a discharge port, and the middle area is located in the area directly above the discharge port, thereby further improving the flowability of the material. Specifically, in this embodiment, the discharge port of the feeding chamber is located at the bottom of the feeder 20, while the feeding channel 10 is located above the dispensing head. The end of the extension section 11 is vertically aligned with the discharge port, so that the middle area of the feeding chamber is vertically aligned with the discharge port. In this way, when the material is conveyed from the feeding channel 10 into the feeding chamber, the material can slide directly from the end of the extension section 11 and fall vertically to the discharge port under the action of gravity, and then leave the feeding chamber from the discharge port. This reduces the lateral displacement of the material during the feeding process, avoids the accumulation and blockage of the material in the feeding chamber, and thus improves the accuracy and efficiency of dispensing. It should be noted that the end of the extension section 11 refers to the end of the extension section 11 away from the outlet end of the feeding channel 10, that is, the end closer to the dispensing head.
[0033] Preferably, the central region and the region directly above the discharge port are coaxially arranged along the material conveying direction of the feeder 20. Specifically, in this embodiment, the end of the extension section 11 extends directly above the discharge port. The material falls vertically within the feeder 20 under the influence of gravity, therefore the material conveying direction of the feeder 20 is vertical. By aligning the central region and the region directly above the discharge port in the vertical direction, the material falling from the extension section 11 can be directly output from the discharge port under the influence of gravity, without accumulating inside the feeding chamber, thus further avoiding material accumulation. It should be noted that in this embodiment, coaxial arrangement along the material conveying direction of the feeder 20 means that both the central region and the region directly above the discharge port are located on the vertical axis of the feeder 20. Figure 3 As shown, in this embodiment, along the material conveying direction, the extension section 11 includes a first section 111 and a second section 112 that are bent and connected. The first section 111 is connected to the outlet end of the feeding channel 10, and the end of the second section 112 extends into the middle region. The acute angle formed by the first section 111 and the longitudinal direction is larger than the acute angle formed by the second section 112 and the longitudinal direction, so that the material can be smoothly conveyed along the feeding channel 10 and can quickly fall to the discharge port of the discharge head. Specifically, the extension direction of the first segment 111 is parallel to the material conveying direction of the feeding channel 10, so that the material is smoothly conveyed from the outlet end of the feeding channel 10 to the first segment 111. When the material is conveyed to the second segment 112, the material needs to extend from the end of the second segment 112 away from the first segment 111 into the middle area. Therefore, the inclination angle of the second segment 112 relative to the horizontal plane is set to be larger than that of the first segment 111 relative to the horizontal plane, so that the material can fall smoothly to the dispensing head, avoiding material contact in the second segment 112, thereby improving the material conveying efficiency. Optionally, multiple transition segments 113 can be set between the first segment 111 and the second segment 112. The acute angle formed by the transition segment 113 and the longitudinal direction is smaller than the acute angle formed by the first segment 111 and the longitudinal direction, and larger than the acute angle formed by the second segment 112 and the longitudinal direction, so that the inclination direction of the extension segment 11 does not change drastically, which is conducive to the smooth conveying and smooth falling of the material. Figure 6 As shown, in this embodiment, a transition section 113 is provided. Of course, depending on actual needs, the extension direction of the first section 111 can be slightly adjusted, as long as the material conveying efficiency is guaranteed.
[0034] like Figure 1 , Figure 2As shown, in this embodiment, the drug feeding mechanism further includes a feeder 30, which is driven to connect with the feeding channel 10. The feeder 30 drives the feeding channel 10 to vibrate in order to convey the material. Specifically, in this embodiment, the feeder 30 is disposed below the feeding channel 10 and is integrated with the feeding channel 10. When the feeder 30 vibrates, it can drive the feeding channel 10 to vibrate. At the same time, under the action of gravity, the material can be conveyed along the extension direction of the feeding channel 10 to the outlet end of the feeding channel 10.
[0035] like Figure 2 As shown, in this embodiment, the drug feeding mechanism further includes a base 40 and an elastic element 50. The elastic element 50 is disposed between the feeder 30 and the base 40, thereby isolating the vibration of the feeder 30 and reducing the vibration of the base 40 and the noise of the drug feeding structure. Specifically, the base 40 serves as a support component for the entire drug feeding mechanism and can be connected to components such as the feeder 20 and the elastic element 50 to improve the stability of the drug feeding mechanism. An elastic element 50 is disposed below the feeder 30, and the base 40 is disposed below the elastic element 50. Both ends of the elastic element 50 are connected to the feeder 30 and the base 40, respectively. The elastic element 50 supports the feeder 30 and the feeding channel 10. Simultaneously, when the feeder 30 is working, the vibration generated by the feeder 30 is transmitted downwards to the elastic element 50, where it is absorbed. This prevents the vibration of the feeder 30 from being transmitted to other components through the base 40, thus ensuring the overall stability of the drug feeding mechanism and reducing operating noise.
[0036] Optionally, the elastic element 50 can be a shock-absorbing spring. Depending on the actual situation, the elastic element 50 can be configured as one or more, such as... Figure 4 , Figure 6 As shown, this embodiment has four elastic elements 50, and the base 40 has a horizontal mounting surface. The four elastic elements 50 are symmetrically arranged on the mounting surface to ensure the stability of the feeder 30 and the feeding channel 10.
[0037] In this embodiment, the drug feeding mechanism further includes a first flexible member 60, which is disposed between the feeding channel 10 and the feeder 20. The feeding channel 10 and the feeder 20 are flexibly connected, thereby absorbing the vibration generated by the feeder 30 and preventing the vibration from being transmitted to other components, thus reducing the noise of the drug feeding mechanism. Specifically, the feeding channel 10 in this embodiment also includes a main body 12, which is circumferentially closed and has inlets and outlets at both ends, i.e., a tubular structure. Figure 5As shown, along the width direction of the feeding channel 10, the width of the extension section 11 can be set slightly smaller than the width of the main body 12, thereby providing space for the installation of the first flexible member 60. This allows the first flexible member 60 to be fitted over the extension section 11 after installation, and the joint between the first flexible member 60 and the main body 12 can be aligned. The extension section 11 is connected to the main body 12 along the material conveying direction. The extension section 11 is configured as an inclined plate structure, and the extension section 11 is connected to the bottom of the main body 12, thereby achieving continuous material conveying. A feed inlet is provided at the top edge of the feeder 20 near the feeding channel 10, and the first flexible member 60 is provided between the feed inlet and the extension section 11. It should be noted that the width direction of the feeding channel 10 refers to the horizontal direction perpendicular to the material conveying direction.
[0038] Optionally, the first flexible member 60 can be configured as a flexible connection structure such as a hose. The first flexible member 60 is sleeved on the extension section 11. On the one hand, the first flexible member 60 can absorb the vibration generated by the feeder 30, preventing the vibration transmitted from the feeder 30 to the feeding channel 10 from being transmitted to other components of the drug feeding mechanism. On the other hand, the first flexible member 60 can act as a seal, preventing material from falling from the extension section 11. In this embodiment, the extension section 11 passes through the interior of the first flexible member 60 and extends to the middle region of the feeder 20, preventing material from accumulating at the hose connection, thereby optimizing the material conveying process. Due to the flexibility of the first flexible member 60, its transmission effect is relatively poor. The extension section 11, located inside the first flexible member 60, compensates for this poor transmission effect, facilitating normal material conveying. Simultaneously, the end of the extension section 11 extending into the feeder 20 does not contact the inner wall of the feeder 20, preventing the vibration of the feeding channel 10 from being transmitted to the feeder 20.
[0039] In this embodiment, the first flexible member 60 is a flexible tube, and the first segment 111 of the extension section 11 passes through the first flexible member 60. The second segment 112 and the transition section 113 of the extension section 11 extend into the feeding cavity. Considering that the extension direction of the first flexible member 60 is in the same direction as the extension direction of the feeding channel 10, which can make the appearance of the drug feeding mechanism more aesthetically pleasing, the acute angle formed between the first segment 111 of the extension section 11 and the vertical direction is set to be slightly larger than the acute angle formed between the extension direction of the feeding channel 10 and the vertical direction. This makes the overall appearance of the drug feeding mechanism follow the inclined direction of the feeding channel 10, and at the same time, it facilitates the assembly of the first flexible member 60 and the feeding channel 10.
[0040] In this embodiment, the drug feeding mechanism further includes a storage component 70 and a second flexible component 80. The storage component 70 is connected to the feeding channel 10, and the second flexible component 80 is disposed between the storage component 70 and the feeding channel 10. The storage component 70 and the feeding channel 10 are flexibly connected, thereby absorbing the vibration generated by the feeder 30 and reducing the noise of the drug feeding mechanism. Specifically, the feeding channel 10 also has an inlet end, and the storage component 70 is disposed at the inlet end of the feeding channel 10. The inlet end and the outlet end are opposite to each other and are the two ends of the feeding channel 10, respectively. In this embodiment, the inlet end is higher than the outlet end, which is beneficial for material conveying. To facilitate feeding, the inlet end of the feeding channel 10 in this embodiment opens upward, and the storage component 70 is disposed above the inlet end to facilitate connection with the feeding channel 10. The material flows from the storage component 70 through the feeding channel 10 into the feeder 20. The second flexible component 80 is similar to the first flexible component 60 and can also be configured as a flexible connection structure such as a hose. The second flexible member 80 connects the storage member 70 and the inlet end of the feeding channel 10. Its function is similar to that of the first flexible member 60. On one hand, the second flexible member 80 can absorb the vibration generated by the feeder 30, preventing the vibration from being transmitted to other components. On the other hand, since the second flexible member 80 is designed as a flexible hose, it can act as a seal, preventing material from flowing out from the gap between the storage member 70 and the inlet end of the feeding channel 10. Thus, the first flexible member 60 and the second flexible member 80, positioned at both ends of the feeding channel 10, not only serve as isolation and shock absorption, preventing the vibration of the feeding channel 10 from being transmitted to other components of the drug feeding mechanism, thereby significantly reducing the noise of the drug feeding mechanism and making the working environment more comfortable, but also eliminate assembly errors caused by the deformation of the elastic member 50, facilitating the assembly of the feeding channel 10.
[0041] Optionally, the storage unit 70 can be configured as a hopper, which can be connected to the base 40 using angle iron. The bottom of the hopper has an opening, which is connected to the inlet end of the feeding channel 10 via a second flexible member 80. In this embodiment, the speed at which material flows out of the storage unit 70 is jointly determined by the feeder 30 and the feeding channel 10. The inclination of the feeding channel 10 can affect the speed at which material flows out, and the vibration intensity and frequency of the feeder 30 can also adjust the speed at which material flows out of the storage unit 70.
[0042] In this embodiment, the drug feeding mechanism also includes a weighing device 90. The feeder 20 has a discharge port, and the weighing device 90 is located below the discharge port, thereby enabling precise control of the weight of the material fed by the feeder 20 to ensure accurate dosage each time, thus improving the accuracy and reliability of drug dispensing. Specifically, the feeder 20 has a discharge port at its bottom, and the weighing device 90 is positioned in the direction of the discharge port, so that after the material falls from the extension section 11, it passes through the feeding chamber and falls directly onto the weighing device 90 for weighing.
[0043] The drug feeding structure of this embodiment optimizes the layout of the feeding channel 10, making the feeding channel 10 inclined, and setting an extension section 11 extending into the middle area of the feeder 20, thereby making the feeding smoother and solving the problems of poor flowability, low material conveying efficiency, and easy blockage during the drug dispensing process. This embodiment also introduces shock-absorbing structures such as elastic element 50, first flexible element 60, and second flexible element 80, thereby effectively improving the material conveying efficiency and reducing equipment noise.
[0044] It should be noted that "multiple" in the above embodiments refers to at least two.
[0045] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0046] 1. This technology solves the problem of material blockage during the conveying process in existing technologies;
[0047] 2. The feeding channel is set at an angle to assist the flow of materials with gravity, thereby improving the fluidity of the materials;
[0048] 3. The end of the extension section extends into the middle area of the feeding chamber, thereby ensuring that the material enters the center of the feeder accurately and without error, avoiding material accumulation on the inner wall of the feeding chamber, thereby further improving the flowability of the material, thus improving the smoothness and efficiency of material conveying, and thus improving the dispensing efficiency.
[0049] 4. The first and second flexible components are set at both ends of the feeding channel. They not only serve to isolate and dampen vibrations, preventing the vibrations of the feeding channel from being transmitted to other parts of the drug feeding mechanism, thereby significantly reducing the noise of the drug feeding mechanism and making the working environment more comfortable, but also eliminate assembly errors caused by the deformation of the elastic components, making the assembly of the feeding channel more convenient.
