Description

Technical Field

[0001] This invention relates to the field of dust removal technology, and more specifically to a dust removal device for a blood-activating and meridian-clearing capsule filling machine. Background Technology

[0002] The Huoxue Tongmai Capsules are composed of a variety of traditional Chinese medicines, including leeches, salvia miltiorrhiza, angelica sinensis, astragalus membranaceus, trichosanthes peel, hawthorn, earthworm, and rhubarb. In addition, other ingredients such as chicken blood vine, peach kernel, red peony root, safflower, sandalwood, turmeric, notoginseng, chuanxiong rhizome, tangerine peel, costus root, acorus tatarinowii, wolfberry, polygonatum sibiricum (wine-processed), ginseng, ophiopogon japonicus, and borneol are also used in the Huoxue Tongmai Capsules.

[0003] In the production process of Huoxue Tongmai Capsules, medicinal powder needs to be filled into the capsule shell using a filler. The capsule filling machine generally adopts an automatic intermittent rotary motion. The rotary table, installed in the center of the worktable, has multiple short pauses per revolution, during which the rotary table transports the capsules to various workstations around it. During the short pauses at each station, various operations such as capsule placement, capsule separation, filling, waste capsule removal, capsule locking, capsule ejection, and mold cleaning are performed automatically simultaneously.

[0004] Existing capsule filling machines have some shortcomings in operation, as follows:

[0005] Existing capsule filling machines inspect the filling amount and capsule shape during operation. If they fail to meet the requirements, they are rejected as defective products. During the filling process, static electricity and other factors can cause the medicine powder to scatter inside the machine. The medicine powder is in the form of dust. The dust removal work of the capsule filling machine is mainly to collect the scattered medicine powder inside the machine. However, during the use of the capsule filling machine, the dust removal device will cause the inside of the machine to be connected to the outside air, which is not conducive to maintaining the cleanliness of the inside of the machine. In addition, because there is a processing and filling mechanism inside the machine, it is not possible to effectively remove the medicine powder. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dust removal device for a blood-activating and meridian-clearing capsule filling machine to solve the problems existing in the background art.

[0007] The present invention provides the following technical solution: a dust removal device for a blood-activating and meridian-clearing capsule filling machine, comprising a positioning base, a working box fixedly connected to the top of the positioning base, a feeding device installed on the top of the working box, a dust removal component fixedly connected to one side and the back of the working box, an air intake component fixedly connected to the other side of the working box, a filling component fixedly connected to the top of the positioning base, and a conveying disc fixedly connected to the top of the positioning base.

[0009] Furthermore, the positioning box includes a first box, a square groove on one side of the first box, a circular groove on the other side of the first box, a flow guide square tube fixedly connected to the bottom of the first box, a support box fixedly connected to the bottom of the flow guide square tube, a screening square groove on the bottom of the support box, a filter drawer provided inside the screening square groove, and a rotating baffle installed on one side of the flow guide square tube.

[0010] Furthermore, the fan assembly includes a movable square plate, a limiting square ring is fixedly installed on the other side of the outer side of the movable square plate, a servo motor is fixedly connected to one side of the movable square plate, a connecting plate is fixedly connected to the top of the servo motor, a hydraulic rod is fixedly connected to the top of the other side of the connecting plate, a hydraulic cylinder is fixedly connected to the other side of the hydraulic rod, a rotating shaft is fixedly connected to the output shaft of the servo motor, and a fan blade assembly is fixedly connected to the other side of the outer side of the rotating shaft.

[0011] Furthermore, the fan blade assembly includes a fan blade body, the fan blade body has rounded corners on both sides, a positioning shaft is installed at the bottom of the fan blade body, a positioning plate is fixedly connected to the bottom of the positioning shaft, and a torque spring is fixedly connected to the bottom of the inner side of the positioning plate.

[0012] Furthermore, the screening assembly includes a first screening plate, a first screening hole on the top of the first screening plate, telescopic rods installed at the four corners of the bottom of the first screening plate, a second screening plate installed at the bottom of the telescopic rods, a square sealing block fixedly connected to the top of the second screening plate, and a second screening hole on the top of the second screening plate.

[0013] Furthermore, the outer diameter of the fan blade assembly is three centimeters larger than the outer diameter of the circular groove, the side of the sealing block has a circular hole, the diameter of the circular hole of the sealing block and the diameter of the outer diameter of the fan blade assembly are fitted with a clearance, and the size of the movable square plate and the size of the square groove are fitted with a clearance.

[0014] Furthermore, the bottom of the inner side of the filter drawer is a filter screen, and a flow guide groove is provided at the bottom of the first box. The size of the flow guide groove of the first box is the same as the size of the inner side of the flow guide square tube, and the size of the outer side of the sealing block matches the size of the inner side of the first box.

[0015] Furthermore, the size of the first screening hole and the size of the square sealing block are fitted with a clearance, the size of the first screening plate and the size of the second screening plate are matched with each other, one side of the top of the first screening plate and the bottom of the rotating baffle are on the same plane, and the structure of the air intake assembly is the same as that of the positioning box and the fan assembly except for the servo motor.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. In this invention, when the capsule filling machine completes a specified working time or when excessive powder is scattered inside the equipment due to static electricity or other reasons, the hydraulic cylinder extends the hydraulic rod, which in turn moves the connecting plate and servo motor to the right. This, in turn, moves the moving square plate, the limiting square ring, the rotating shaft, and the fan blade assembly to the right. As the fan blade assembly moves to the right, its left side moves away from the left side of the first housing. Under the action of the torque spring, the fan blade body rotates 30 degrees along the positioning shaft. The distance the fan assembly moves to the right must ensure that the fan blade assembly will not contact the inside of the first housing after unfolding. At this time, the fan blade assembly is located inside the sealing block. Then, the servo motor drives the rotating shaft to rotate, simultaneously rotating the fan blade assembly to extract gas from the inside of the working housing. Simultaneously, the components in the air intake assembly that have the same structure as the fan blade assembly open, allowing outside air to enter the working chamber. Under the action of air circulation, the powder inside the working chamber enters the positioning chamber. Then, the fan blade assembly blows the gas and powder into the guide square tube. Under the action of gas pressure, the telescopic rod extends, which in turn separates the first and second screening plates. This causes the square sealing block to move away from the first screening hole, allowing the gas to enter the bottom of the screening assembly through the first and second screening holes. Then, the powder and gas are separated by the filter screen at the bottom of the filter drawer. This effectively removes the powder scattered inside the equipment, ensuring the cleanliness of the equipment. Moreover, the cleaning method is to use the circulating air to move the powder, avoiding the inconvenience of manual cleaning.

[0018] 2. After cleaning, the present invention uses a hydraulic cylinder to shorten the hydraulic rod, causing the fan assembly to return to its original position. When the fan blade assembly returns to its original position, the pressure from the inner wall of the first housing causes the fan blade assembly to rotate to its original position and form a circular plate, sealing the circular groove. When there is no gas blowing, the screening assembly will spring back to its original position and seal the first screening hole with a square sealing block. The two seals isolate the inside of the equipment from the outside air, effectively ensuring the cleanliness of the inside of the equipment and ensuring effective isolation between the inside and outside air during the operation of the equipment.

[0019] 3. This invention limits the rotation angle of the fan blade body by using a torque spring and limits the movement of the moving square plate by using a limiting square ring, thus ensuring the normal operation of the dust removal component. In addition, a filter screen can be placed on the top of the screening component to remove unqualified capsule shells according to actual needs. The removed capsule shells can be taken out by rotating the baffle, making the equipment adaptable to more usage situations. Attached Figure Description

[0030] In a preferred embodiment, the dust removal assembly 4 includes a positioning box 401, a fan assembly 402 is installed on the top of the inner side of the positioning box 401, a screening assembly 403 is installed on the inner side of the positioning box 401, a guide block 405 is installed on one side of the top of the inner side of the positioning box 401, and a sealing block 404 is installed on the other side of the inner side of the positioning box 401.

[0031] In a preferred embodiment, the positioning box 401 includes a first box 4011, a square groove 4013 is provided on one side of the first box 4011, a circular groove 4012 is provided on the other side of the first box 4011, a flow guide square tube 4014 is fixedly connected to the bottom of the first box 4011, a support box 4015 is fixedly connected to the bottom of the flow guide square tube 4014, a screening square groove 4016 is provided at the bottom of the support box 4015, a filter drawer 4017 is provided inside the screening square groove 4016, and a rotating baffle 4018 is installed on one side of the flow guide square tube 4014.

[0032] In a preferred embodiment, the fan assembly 402 includes a movable square plate 4021, a limiting square ring 4022 fixedly installed on the other side of the movable square plate 4021, a servo motor 4023 fixedly connected to one side of the movable square plate 4021, a connecting plate 4024 fixedly connected to the top of the servo motor 4023, a hydraulic rod 4025 fixedly connected to the top of the other side of the connecting plate 4024, a hydraulic cylinder 4026 fixedly connected to the other side of the hydraulic rod 4025, a rotating shaft 4027 fixedly connected to the output shaft of the servo motor 4023, and a fan blade assembly 4028 fixedly connected to the other side of the rotating shaft 4027; after cleaning... The hydraulic cylinder 4026 drives the hydraulic rod 4025 to shorten, causing the fan assembly 402 to return to its original position. When the fan blade assembly 4028 returns to its original position, the pressure from the inner wall of the first housing 4011 causes the fan blade assembly 4028 to rotate to its original position and form a circular plate, which seals the circular groove 4012. When there is no gas blowing, the screening assembly 403 will spring back to its original position and seal the first screening hole 4032 through the square sealing block 4035. The two seals isolate the inside of the equipment from the outside air, effectively ensuring the cleanliness of the inside of the equipment and ensuring effective isolation between the inside and outside air during the operation of the equipment.

[0033] In a preferred embodiment, the fan blade assembly 4028 includes a fan blade body 40281, with rounded corners 40282 on both sides of the fan blade body 40281. A positioning shaft 40283 is installed at the bottom of the fan blade body 40281, and a positioning plate 40285 is fixedly connected to the bottom of the positioning shaft 40283. A torque spring 40284 is fixedly connected to the bottom of the inner side of the positioning plate 40285. The rotation angle of the fan blade body 40281 is limited by the torque spring 40284, and the movement of the moving square plate 4021 is limited by the limiting square ring 4022, ensuring the normal operation of the dust removal assembly 4. According to actual needs, a filter screen can be placed on the top of the screening assembly 403 to remove unqualified capsule shells. The removed capsule shells can be taken out by rotating the baffle 4018, making the equipment adaptable to more usage situations.

[0034] In a preferred embodiment, the sieving assembly 403 includes a first sieving plate 4031, a first sieving hole 4032 on the top of the first sieving plate 4031, telescopic rods 4033 installed at the four corners of the bottom of the first sieving plate 4031, a second sieving plate 4034 installed at the bottom of the telescopic rods 4033, a square sealing block 4035 fixedly connected to the top of the second sieving plate 4034, and a second sieving hole 4036 on the top of the second sieving plate 4034; when the capsule filling machine completes a specified working time or when too much powder is scattered inside the equipment due to static electricity or other reasons, the hydraulic cylinder 4026... The operation causes the hydraulic rod 4025 to extend, which in turn moves the connecting plate 4024 and the servo motor 4023 to the right. This, in turn, moves the moving square plate 4021, the limiting square ring 4022, the rotating shaft 4027, and the fan blade assembly 4028 to the right. As the fan blade assembly 4028 moves to the right, its left side moves away from the left side inside the first housing 4011. Under the action of the torque spring 40284, the fan blade body 40281 rotates 30 degrees along the positioning shaft 40283. The distance the fan assembly 402 moves to the right must ensure that the fan blade assembly 4028 does not... The fan blade assembly 4028 will contact the inner side of the first housing 4011, and at this time, the fan blade assembly 4028 is located inside the sealing block 404. Then, the servo motor 4023 drives the rotating shaft 4027 to rotate, which in turn drives the fan blade assembly 4028 to rotate, drawing gas from the inside of the working housing 2. At the same time, the component in the air intake assembly 7 with the same structure as the fan blade assembly 4028 opens, allowing outside air to enter the working housing 2. Under the action of air circulation, the powder inside the working housing 2 enters the positioning housing 401. Then, the fan blade assembly 4028 blows the gas and powder into the guide tube 4014. Under the action of body pressure, the telescopic rod 4033 extends, which in turn separates the first screening plate 4031 and the second screening plate 4034. This causes the square sealing block 4035 to move away from the first screening hole 4032, allowing the gas to enter the bottom of the screening assembly 403 through the first screening hole 4032 and the second screening hole 4036. Then, the powder is separated from the gas by the filter screen at the bottom of the filter drawer 4017. This effectively removes the powder scattered inside the equipment, ensuring the cleanliness of the equipment. The cleaning method uses circulating air to move the powder, avoiding the inconvenience of manual cleaning.

[0035] In a preferred embodiment, the outer diameter of the fan blade assembly 4028 is three centimeters larger than the outer diameter of the circular groove 4012, a circular hole is provided on the side of the sealing block 404, the diameter of the circular hole of the sealing block 404 and the diameter of the outer diameter of the fan blade assembly 4028 are clearance-fitted, and the size of the movable square plate 4021 is clearance-fitted with the size of the square groove 4013.

[0036] In a preferred embodiment, the bottom of the inner side of the filter drawer 4017 is a filter screen, and the bottom of the first housing 4011 is provided with a flow guide groove. The size of the flow guide groove of the first housing 4011 is the same as the size of the inner side of the flow guide square tube 4014, and the size of the outer side of the sealing block 404 matches the size of the inner side of the first housing 4011.

[0037] In a preferred embodiment, the dimensions of the first screening hole 4032 and the square sealing block 4035 are fitted with a clearance, the dimensions of the first screening plate 4031 and the second screening plate 4034 are fitted together, one side of the top of the first screening plate 4031 and the bottom of the rotating baffle 4018 are on the same plane, and the structure of the air intake assembly 7 is the same as that of the positioning box 401 and the fan assembly 402 except for the servo motor 4023.

[0038] The working principle of this invention is as follows: When the capsule filling machine completes a specified working time or when too much powder is scattered inside the equipment due to static electricity or other reasons, the hydraulic cylinder 4026 drives the hydraulic rod 4025 to extend, which in turn drives the connecting plate 4024 and the servo motor 4023 to move to the right. This, in turn, drives the moving square plate 4021, the limiting square ring 4022, the rotating shaft 4027, and the fan blade assembly 4028 to move to the right. When the fan blade assembly 4028 moves to the right, the left side of the fan blade assembly 4028... The fan assembly 402 will move away from the left side inside the first housing 4011, thus, under the action of the torque spring 40284, the fan blade body 40281 will rotate 30 degrees along the positioning shaft 40283. The distance the fan assembly 402 moves to the right needs to ensure that the fan blade assembly 4028 will not contact the inside of the first housing 4011 after unfolding. At this time, the fan blade assembly 4028 is located inside the sealing block 404. Then, the servo motor 4023 drives the rotating shaft 4027 to rotate, and at the same time drives the fan blade assembly... Rotation of 4028 extracts gas from the inside of the working chamber 2. Simultaneously, the component in the air intake assembly 7, which has the same structure as the fan blade assembly 4028, opens, allowing outside air to enter the working chamber 2. Under the action of air circulation, the powder inside the working chamber 2 enters the positioning chamber 401. Then, the fan blade assembly 4028 blows the gas and powder into the guide square tube 4014. Under the action of gas pressure, the telescopic rod 4033 extends, thereby causing the first screening plate 4031 and the second screening plate 4033 to extend. The plate 4034 separates, which in turn moves the square sealing block 4035 away from the first screening hole 4032. This allows the gas to enter the bottom of the screening assembly 403 through the first screening hole 4032 and the second screening hole 4036. Then, the powder is separated from the gas by the filter screen at the bottom of the filter drawer 4017. This effectively removes the powder scattered inside the equipment, ensuring the cleanliness of the equipment. The cleaning method uses circulating air to move the powder, avoiding the inconvenience of manual cleaning.

[0039] After cleaning, the hydraulic cylinder 4026 drives the hydraulic rod 4025 to shorten, causing the fan assembly 402 to return to its original position. When the fan blade assembly 4028 returns to its original position, the fan blade assembly 4028 will rotate to its original position under the pressure of the inner wall of the first housing 4011, forming a circular plate that seals the circular groove 4012. When there is no gas blowing, the screening assembly 403 will spring back to its original position and seal the first screening hole 4032 through the square sealing block 4035. The two seals isolate the inside of the equipment from the outside air, effectively ensuring the cleanliness of the inside of the equipment and ensuring effective isolation between the inside and outside air during the operation of the equipment.

[0040] The rotation angle of the fan blade body 40281 is limited by the torque spring 40284, and the movement of the moving square plate 4021 is limited by the limiting square ring 4022, which ensures the normal operation of the dust removal component 4. In addition, a filter screen can be placed on the top of the screening component 403 according to actual needs to remove unqualified capsule shells. The removed capsule shells can be taken out by rotating the baffle 4018, so that the equipment can adapt to more usage situations.
