Description

Technical Field

[0001] This invention relates to the field of capsule manufacturing equipment, and in particular to a feeding device and a capsule machine. Background Technology

[0002] When capsule machines are filling microcapsules, manual butterfly valves are often used to control the presence or absence of microcapsules in the capsule machine's feeding device. The opening and closing of the butterfly valve is controlled by gravity to control the microcapsules in the feeding device. However, the microcapsules are easily cracked or broken during the opening and closing of the butterfly valve.

[0003] Furthermore, in existing technologies, the level of micro-flakes is often controlled by the distance between the feeding pipe and the bottom of the rotating hopper. However, during the operation of the capsule machine, the rotating hopper rotates counterclockwise under the drive of the servo motor. The micro-flakes move along the rotation direction under the drive of the rotating hopper, causing a large number of micro-flakes to move upward. Then, the micro-flakes in the feeding pipe flow back into the rotating hopper under the action of gravity. A large number of micro-flakes will be stored in the rotating hopper. The micro-flakes slide and rub against each other, generating powder and static electricity, which will affect the next filling process, causing blockage of metering holes, filling tubes, etc., or the micro-flakes will be electrostatically adsorbed on the inner wall of the filling tube and unable to fall into the capsule, resulting in economic losses.

[0004] The existing capsule machine feeding device has the following disadvantages:

[0005] 1. It is impossible to determine the level of micro-flakes in the feeding device without ensuring that the micro-flakes are not damaged;

[0006] 2. It is impossible to accurately control the appropriate material level to ensure the stability of filling;

[0007] 3. The distance between the feed pipe and the bottom of the granule filling device needs to be constantly adjusted, and the adjustment time is relatively long;

[0008] 4. Improper installation of the feed pipe leads to wear and tear on the micro-plates, generating static electricity, resulting in low product yield and serious material waste.

[0009] Therefore, how to improve the product yield of the feeding device and save costs is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

The material level detection assembly includes a material level sensor and a bracket. The bracket is fixed on the central support, the material level sensor has a scale line, and the material level sensor is mounted on the bracket in an adjustable position.

[0022] Preferably, it also includes an extension tube, one end of which is connected to the feeding hopper and the other end of which is connected to the feed inlet of the housing.

[0023] Preferably, the width of the gap is 1.5-2.5 times the particle size of the material.

[0024] Preferably, the housing includes a housing body, a connecting seat, and a feeding connector. The connecting seat is detachably connected to the end of the housing body near the feeding hopper, and the feeding connector is detachably connected to the end of the housing body near the filling assembly. Furthermore, there is a material spill space between the housing body and the internal feeding pipe.

[0025] Preferably, the connecting seat includes a first connecting part, a second connecting part, and a third connecting part. The first connecting part, the second connecting part, and the third connecting part are all cylindrical, and the third connecting part is sleeved on the outer periphery of the second connecting part. The first connecting part is connected to the feeding hopper, the internal feeding pipe is sleeved on the outer periphery of the second connecting part, and the third connecting part is connected to the end of the housing body.

Detailed Implementation

[0036] The core of this invention is to provide a feeding device and a capsule machine that can improve filling efficiency and accurately determine the material level.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of a specific embodiment of the feeding device provided by the present invention; Figure 2 for Figure 1 A longitudinal cross-sectional view of the switching assembly in the feeding device shown; Figure 3 for Figure 2 The AA cross-sectional view of the switch assembly shown; Figure 4 for Figure 1 An enlarged structural diagram of the filling component and the light-emitting component in the feeding device shown.

[0039] In this embodiment, the feeding device includes:

[0040] Feed hopper 2, for material to fall into;

[0041] The switch assembly 4 is connected to the feeding hopper 2 and is used to release or prevent the release of material;

[0042] Counting and filling assembly 1, used to carry materials and perform filling;

[0043] The material level detection component 6 is installed inside the counting and filling component 1 and is used to detect the material level inside the counting and filling component 1.

[0044] The controller is used to acquire the material level detection result of the material level detection component 6 and control the action of the switch component 4 according to the material level detection result;

[0045] Furthermore, the switch assembly 4 includes a housing, an internal feed tube 42 located inside the housing, a feed baffle 45 located below the internal feed tube 42, and a drive component 47 for pushing the feed baffle 45 to move horizontally. The feed baffle 45 blocks or releases the outlet of the internal feed tube 42. A first protective layer 44 is provided on the side of the feed baffle 45 near the internal feed tube 42, and there is a gap between the feed baffle 45 and the internal feed tube 42. The controller is connected to the drive component 47.

[0046] Specifically, the feeding hopper 2 is located at the top of the entire device and is installed on the top cover 9 of the capsule machine. The capsule machine can fill powder, pills, tablets, and microcapsules into capsules. The counting and filling component 1 fills a fixed number of microcapsules into capsules and is a functional module of the capsule machine. This feeding device is mainly used for feeding and filling microcapsules in the capsule machine. Microcapsules are a type of tablet, mainly referring to tablets with a diameter of 2-4mm and a thickness of 2-4mm. The counting and filling component 1 of the capsule machine can accurately control the amount of material in the capsules, allowing qualified capsules to flow into the finished product bin and other defective capsules to flow into the waste bin. In this process, the material level control in the rotating hopper 13 plays a crucial role. The material level detection component 6 is used to detect the material level in the rotating hopper 13 and feed the detection result back to the controller. If the material level in the rotating hopper 13 is too low, it will result in too many defective capsules, affecting the overall product yield and material waste. If the material level in the rotating hopper 13 is too high, it will cause the material to continuously slide inside the rotating hopper 13, generating static electricity and affecting the next filling step. At the same time, the material level detection component 6 can also detect the presence or absence of material, thereby facilitating the assembly, disassembly, and cleaning of the capsule filling component 1 by operators.

[0047] The feeding device provided by this invention uses a switch assembly 4 to control the feeding of materials and a material level detection assembly 6 to detect the material level. Then, a drive component 47 controls the feeding baffle 45 to move horizontally to block or release the material in the internal feeding pipe 42. By setting a gap between the feeding baffle 45 and the internal feeding pipe 42, the material is prevented from being damaged during the horizontal movement of the feeding baffle 45. This avoids the problem of material being easily cracked or crushed by butterfly valves in the prior art. At the same time, due to the setting of the switch assembly 4, after the feeding baffle 45 blocks the outlet of the internal feeding pipe 42, no more material falls into the main feeding pipe 5. During the operation of the multi-granule filling assembly 1, there is less friction between materials, avoiding the generation of static electricity and effectively improving the product yield.

[0048] In some embodiments, the switch assembly 4 further includes a limiting block 49 for restricting the direction of the discharge baffle 45. The limiting block 49 is installed inside the housing and has a limiting portion that abuts against the side surface of the discharge baffle 45 near the internal discharge pipe 42. Specifically, the limiting block 49 serves as a horizontal holding block for the discharge baffle 45 to resist the gravity from the drive component 47. The side of the limiting block 49 near the internal discharge pipe 42 has a step, which forms the limiting portion. The limiting portion can press against the surface of the discharge baffle 45. When the surface of the discharge baffle 45 is provided with a first protective layer 44, the limiting portion presses against the first protective layer 44. During the left and right translation of the discharge baffle 45, it will not tilt upwards, thereby preventing the distance between the discharge baffle 45 and the first main discharge pipe 5 from being too small and damaging the material.

[0049] In some embodiments, the switch assembly 4 further includes a mounting block 48 mounted on the outer wall of the housing. The fixed portion of the drive component 47 is mounted on the mounting block 48, and the telescopic portion of the drive component 47 extends into the housing and is connected to the discharge baffle 45. The side of the mounting block 48 closest to the housing has the same shape as and fits snugly against the outer wall of the housing. Specifically, one side of the mounting block 48 is arc-shaped, and the arc end of the mounting block 48 is bolted to the outer wall of the housing. The other side of the mounting block 48 is connected to the drive component 47. The drive component 47 is preferably a cylinder, with its telescopic rod extending into the housing and capable of telescopic movement. The telescopic rod is bolted to the discharge baffle 45. Preferably, the distance between the mounting block 48 and the surface of the first protective layer 44 should be ≤0.3mm, which effectively restricts the horizontal movement of the discharge baffle 45 without affecting its translation.

[0050] In some embodiments, a main feed pipe 5 is also included, one end of which is connected to the switching assembly 4, and the other end is suspended inside the fractionation filling assembly 1. Specifically, the main feed pipe 5 is used to convey the material falling from the switching assembly 4 into the fractionation filling assembly 1.

[0051] In some embodiments, the counting and filling assembly 1 includes a rotating hopper 13, a central support column 12, and a scraper 11. The scraper 11 is fixed on the central support column 12. The rotating hopper 13 can rotate relative to the central support column 12, and the rotating hopper 13 is provided with a plurality of metering holes for material to fall into. Specifically, the rotating hopper 13 in the counting and filling assembly 1 rotates counterclockwise under the drive of a servo motor, while the position of the central support column 12 remains stationary. The rotating hopper 13 rotates relative to the central support column 12. Since the scraper 11 is installed on the central support column 12, the rotating hopper 13 will rotate relative to the scraper 11. Under the blocking action of the scraper 11, the material falls from the metering holes in sequence.

[0052] In some embodiments, the material level detection component 6 includes a material level sensor 62 and a bracket. The bracket is fixed on the central support column 12. The material level sensor 62 has scale lines and is mounted on the bracket in an adjustable position. Specifically, the scale of the material level sensor 62 is set from bottom to top. After determining the target material level according to production needs, the corresponding scale in the material level sensor 62 is adjusted to be aligned with the position of the bracket, and then connected by fasteners. In one specific embodiment, one end of the sensor bracket 61 is fixed to the central support column 12 by bolts, and the other end of the sensor bracket 61 is fixed to the material level sensor 62. The material level sensor 62 detects the material level inside the rotating hopper 13 in real time during operation. For example, the distance between the material level sensor 62 and the bottom of the rotating hopper 13 can be 4-6 mm. The outer surface of the material level sensor 62 has scale lines. When reinstalling, the fixing bolts are tightened by aligning with the scale lines.

[0053] In some embodiments, an extension tube 3 is also included, one end of which is connected to the feeding hopper 2, and the other end is connected to the feed inlet of the housing. Specifically, one end of the extension tube 3 is detachably connected to the feeding hopper 2 via a first snap-fit ​​7, and the other end is detachably connected to the switch assembly 4 via a second snap-fit ​​8; furthermore, the extension tube 3 is connected to the connecting seat 41 of the switch assembly 4 for easy assembly.

[0054] In some embodiments, the width of the gap is 1.5-2.5 times the particle size of the material. Specifically, the area of ​​the discharge baffle 45 and the first protective layer 44 should be slightly larger than the cross-sectional area of ​​the inner discharge pipe 42, and the projection of the discharge baffle 45 should completely cover the projection of the inner discharge pipe 42 in the axial projection direction of the inner discharge pipe 42. The distance between the inner discharge pipe 42 and the first protective layer 44, i.e., the width of the gap, is preferably 1.5-2.5 times the diameter of the material, so that while the material falls onto the discharge baffle 45, it is prevented from scattering into the interior of the shell.

[0055] In some embodiments, the housing includes a housing body 43, a connecting seat 41, and a discharge connector 46. The connecting seat 41 is detachably connected to the end of the housing body 43 near the discharge hopper 2, and the discharge connector 46 is detachably connected to the end of the housing body 43 near the multi-granule filling assembly 1. Furthermore, there is a material spill space between the housing body 43 and the internal discharge pipe 42. Specifically, a second protective layer 410 is disposed on the inner wall of the housing body 43 to protect the material spilled from the gap between the internal discharge pipe 42 and the discharge baffle 45. The detachable connection between the housing body 43, the connecting seat 41, and the discharge connector 46 facilitates assembly and disassembly, and allows for convenient arrangement of the internal discharge pipe 42, the limiting block 49, and the discharge baffle 45.

[0056] In some embodiments, the connecting seat 41 includes a first connecting portion 411, a second connecting portion 412, and a third connecting portion 413. All three portions are cylindrical, with the third connecting portion 413 fitted around the outer periphery of the second connecting portion 412. The first connecting portion 411 is connected to the feeding hopper 2, and the internal feeding pipe 42 is fitted around the outer periphery of the second connecting portion 412. The third connecting portion 413 is connected to the end of the housing body 43. Specifically, the cross-section of the third connecting portion 413 is Z-shaped. This facilitates fixing the housing body 43 and allows the internal feeding pipe 42 to separate from the housing body 43, creating a space inside the housing for material to scatter, facilitating the arrangement of the limiting block 49, and simplifying the assembly of the housing body 43. The above-described configuration, through the cylindrical first connecting part 411, second connecting part 412, and third connecting part 413, enables simultaneous connection of the feeding hopper 2, the internal feeding pipe 42, and the housing body 43, facilitating the assembly of the switch assembly 4. Preferably, the connecting base 41 is an integral structure with high strength and a secure connection.

[0057] In some embodiments, the second connecting portion 412 and the third connecting portion 413 are spaced apart to create a gap between the housing body 43 and the discharge baffle 45; a second protective layer 410 is provided on the inner wall of the housing body 43. This arrangement, along with the gap between the second connecting portion 412 and the third connecting portion 413, ensures that the gap between the housing body 43 and the discharge baffle 45 prevents damage to materials impacting the housing body 43 during the discharge baffle 45's extension process.

[0058] In some embodiments, the first protective layer 44 and / or the second protective layer 410 are elastic protective layers. Specifically, the first protective layer 44 and / or the second protective layer 410 are preferably soft silicone protective layers to minimize contact with the material and reduce static electricity generation. Preferably, the first protective layer 44 is bonded to the top of the discharge baffle 45, the second protective layer 410 is bonded to the inner wall of the housing body 43, and the limiting block 49 is installed inside the housing body 43 to ensure the horizontal movement of the discharge baffle 45 and the first protective layer 44.

[0059] In one specific embodiment, the feeding device includes a feeding hopper 2, an extension tube 3, a switch assembly 4, a main feeding tube 5, a material level detection assembly 6, and a counting and filling assembly 1. The feeding hopper 2, extension tube 3, switch assembly 4, and main feeding tube 5 are connected and fixed to the top cover 9 of the capsule machine with bolts. The bottom end of the feeding hopper 2 is connected to the upper end of the extension tube 3 via a first snap-fit ​​7, and the lower end of the extension tube 3 is connected to the upper end of the switch assembly 4 via a second snap-fit ​​8. The main feeding tube 5 is made of soft silicone, with its upper end wrapped around the lower end of the switch assembly 4. The lower end of the main feeding tube 5 is inserted into the rotating hopper 1 of the counting and filling assembly 1. Inside the 3, the material level detection component 6 is also fixed inside the rotating hopper 13 of the counting and filling component 1 via the central support 12 of the counting and filling component 1; the material enters the rotating hopper 13 of the counting and filling component 1 via the feeding hopper 2, extension pipe 3, switch component 4, and main feeding pipe 5, and the material level inside the rotating hopper 13 is detected in real time by the material level detection component 6; in the switch component 4, the upper end of the connecting seat 41 is connected to the lower end of the extension pipe 3 via the second snap-fit ​​8, and the inner feeding pipe 42 is wrapped inside the lower end of the connecting seat 41, that is, the lower end of the second connecting part 412, and the lower end of the connecting seat 41 is outside the extension pipe 3. The lower end of the third connecting part 413 is connected to the upper end of the housing body 43 by bolts, and the lower end of the housing body 43 is connected to the upper end of the feeding connector 46 by bolts. The main feeding pipe 5 is wrapped around the lower end of the feeding connector 46. When the material level sensor 62 does not detect material, the extension rod of the solenoid valve controls the drive component 47 to retract, and the material begins to fall into the rotating hopper 13. When the material level sensor 62 detects material, the extension rod of the drive component 47 extends, and the material will not fall into the rotating hopper 13. Because there is a distance between the internal feeding pipe 42 and the first protective layer 44, and they are both made of soft silicone, the extension... The material will not be damaged during the shrinkage process. There is a gap between the discharge baffle 45 and the housing body 43. Both the first protective layer 44 and the second protective layer 410 are made of soft silicone. The material that collides with the discharge baffle 45 and the first protective layer 44 during the extension process will hit the second protective layer 410. This process will not damage the material. After the material falls into the rotating hopper 13, it will move counterclockwise upward under the driving force of the counterclockwise rotation of the rotating hopper 13 until it is blocked by the scraper 11. The material level sensor 62 is located at a relatively close distance behind the scraper 11, which can ensure that the filling component 1 continues to operate at a low and appropriate material level.

[0060] This feeding device can control the presence or absence of material in the capsule filling component 1 of the capsule machine and the material level in the rotating hopper 13 without damage; it can solve the complicated problem of material level adjustment of the previous device, and can be installed by aligning with the scale line, saving debugging time; it reduces material wear, reduces static electricity generation, and improves product yield.

[0061] In addition to the above-mentioned feeding device, the present invention also provides a capsule machine including the above-mentioned feeding device. For the structure of other parts of the capsule machine, please refer to the prior art, which will not be described in detail here.
