This drug powder not only affects the appearance quality of the capsule, but also may cause uneven distribution of the active ingredients of the medicine, thereby affecting the efficacy. Therefore, after the capsule is filled, it is usually necessary to polish the capsule to remove the excess drug powder.

[0003] Traditional capsule polishing equipment mainly uses mechanical friction to polish capsules. Although this method can remove the drug powder on the surface of the capsule to a certain extent, it has problems such as low efficiency, high labor intensity, and unstable polishing effect. With the development of the pharmaceutical industry and the advancement of technology, more advanced automated polishing equipment has appeared on the market. They rub the capsule surface by rotating the polishing bristles in the polishing cylinder, and are equipped with a dust suction system to collect the drug powder that falls off during the polishing process. However, the existing automatic polishing equipment still faces some challenges. For example, drug powder is easily accumulated inside the polishing drum, and it is easy to agglomerate after being damp, affecting the polishing effect; capsules accumulate in the feeding hopper during the feeding process, which easily leads to blockage of the feeding hopper or uneven polishing; the adaptability to capsules of different specifications is poor, and the parameters cannot be flexibly adjusted to meet diversified production needs.

A casing 106 is provided on the side of the feed pipe 101, and the transmission mechanism 5 is installed in the casing 106.

[0021] Furthermore, a first spiral blade 1041 is provided on the outer end face of the polishing drum 104, polishing bristles 1042 are provided on the surface of the first spiral blade 1041 and the surface of the polishing drum 104, a first air suction hole 1043 is provided on the surface of the polishing drum 104, a docking portion 1044 is provided on the polishing drum 104, the air suction hood 203 includes a sleeve 2031 and a suction pipe 2032, the bottom of the sleeve 2031 and the top of the suction pipe 2032 are connected, the sleeve 2031 is sleeved on the outer end of the docking portion 1044 and is rotatably connected to the polishing drum 104, the outer end face of the docking portion 1044 is provided with a second air suction hole 10441, and the vacuum cleaner 201 is connected to the suction pipe 2032 through the first connecting pipe 202.

[0022] When the driving motor 105 drives the polishing drum 104 to rotate, the first spiral blade 1041 on the surface of the polishing drum 104 drives the capsule particles to move from the feeding hopper 103 to the discharge pipe 1011. During the movement of the capsule, the capsule contacts and rubs with the first spiral blade 1041 and the polishing bristles 1042 on the surface of the polishing drum 104, so that the polishing bristles 1042 sweep the powder on the surface of the capsule. At the same time, the vacuum cleaner 201 cooperates with the first connecting pipe 202 and the suction hood 203 through the docking part 1044 to suck the swept powder into the vacuum cleaner 201 from the first suction hole 1043 and the second suction hole 10441, thereby polishing the capsule. The rotationally connected suction hood 203 and the polishing drum 104 structure allows the polishing drum 104 to maintain negative pressure in the polishing drum while rotating, and to smoothly transport dust particles.

[0023] Furthermore, a shaft tube 1046 rotatably connected to the feed pipe 101 is provided on the side of the polishing drum 104, the slag discharge auger rod 3 includes a central axis 301 and a second spiral blade 302, the central axis 301 passes through the shaft tube 1046 and is rotatably connected thereto, a first tooth bevel 1045 is provided on the shaft tube 1046, a third tooth bevel 303 is provided on the central axis 301, a second tooth bevel 5011 meshing with the first tooth bevel 1045 and the third tooth bevel 303 is provided on the transmission shaft 501, and the diameter of the second spiral blade 302 is equal to the inner diameter of the polishing drum 104.

[0024] When the driving motor 105 drives the polishing drum 104 to rotate, the first tooth umbrella 1045, the second tooth umbrella 5011 and the third tooth umbrella 303 cooperate to drive the slag removal auger rod 3 to rotate in the opposite direction, so that the slag removal auger rod 3 scrapes off the powder attached to the inner wall of the polishing drum 104 due to moisture absorption and transports it to the suction hood 203, and sucks it into the vacuum cleaner 201 through the airflow.

[0025] Furthermore, the sliding screen plate 4 includes a first screen plate 401, a second sieve plate 402 and a connecting plate 403. The first sieve plate 401 is fixedly mounted on the top of the side end surface of the connecting plate 403, and the second sieve plate 402 is fixedly mounted on the bottom of the side end surface of the connecting plate 403. A first slide groove 1031 is provided in the feeding hopper 103, and the sliding screen plate 4 is installed in the first slide groove 1031 and is slidably connected to the feeding hopper 103.

[0026] The feeding speed of the capsules is limited by the first sieve plate 401 and the second sieve plate 402, and there is a certain gap between the first sieve plate 401 and the second sieve plate 402, so that the medicine powder and the empty capsule shells have a certain residence time on the second sieve plate, which is convenient for the vacuum cleaner 201 to suck away the medicine powder and the empty capsule shells.

[0027] Furthermore, a transmission turntable 5012 is arranged on the top of the transmission shaft 501, an eccentric shaft 503 is arranged on the transmission turntable 5012, an ear plate 404 is arranged on the side of the sliding screen plate 4, an axial hole 5041 rotatably connected to the eccentric shaft 503 is arranged on the connecting rod 504, and the end of the connecting rod 504 away from the axial hole 5041 is rotatably connected to the ear plate 404.

[0028] When the driving motor 105 drives the polishing drum 104 to rotate, the polishing drum 104 drives the transmission shaft 501 to rotate through the first tooth bevel 1045 and the second tooth bevel 5011, thereby driving the eccentric shaft 503 on the top of the transmission shaft 501 to rotate. During the rotation of the eccentric shaft 503 around the transmission shaft 501, the sliding screen plate 4 is repeatedly pushed and pulled, thereby driving the sliding screen plate 4 to shake, accelerating the falling of capsules on the sliding screening surface, and avoiding the accumulation of capsules, which causes the capsules to block the sliding screen plate 4 and prevent the material from being discharged normally.

[0029] Furthermore, a suction chamber 1032 is provided on the side of the feeding hopper 103, which slides with the sliding screen plate 4, a contraction section 20321 is provided on the suction pipe 2032, a negative pressure suction hole 20323 is provided on the side of the contraction section 20321, and a second connecting pipe 204 which penetrates the negative pressure suction hole 20323 is provided on the side of the suction chamber 1032.

[0030] When the vacuum cleaner 201 inhales air, the air flow velocity increases due to the reduction in aperture at the contraction section 20321 of the suction tube 2032, thereby forming a negative pressure at the negative pressure suction hole 20323, and suction is performed by the suction chamber 1032. Since the empty shell of the capsule is light in weight and large in volume, the wind resistance is large, and it is affected by the airflow and is sucked into the vacuum cleaner 201 from the suction chamber 1032.

[0031] Furthermore, a driven turntable 502 rotatably connected is provided on the top of the casing 106, a second slide groove 5021 is provided on the upper end surface of the transmission turntable 5012 and the lower end surface of the driven turntable 502, and sliders 5031 slidably matched with the second slide groove 5021 are provided at the upper and lower ends of the eccentric shaft 503, a screw rod 506 rotatably connected is provided in the second slide groove 5021 of the driven turntable 502, a screw hole 5032 matched with the screw rod 506 is provided on the side of the slider 5031, a rotating sleeve 5022 rotatably connected to the casing 106 is provided at the center of the upper end surface of the driven turntable 502, the adjusting knob 505 passes through the rotating sleeve 5022 and is rotatably connected thereto, a fourth toothed umbrella 5051 is provided at the bottom of the adjusting knob 505, and a fifth toothed umbrella 5061 meshing with the fourth toothed umbrella 5051 is provided on the screw rod 506.

[0032] The driven turntable 502 is fixed by pinching the rotating sleeve 5022, and then the adjusting knob 505 is turned to make the adjusting knob 505 drive the screw rod 506 to rotate through the cooperation of the fourth gear umbrella 5051 and the fifth gear umbrella 5061, and the eccentric shaft 503 is driven to slide along the first slide groove 1031 through the cooperation of the screw rod 506 and the slider 5031, so as to adjust the position of the eccentric shaft 503 to change the shaking amplitude of the sliding screen plate 4, thereby adjusting the feeding speed to meet the production requirements of different capsules.

[0033] Furthermore, the side end surfaces of the adjusting knob 505 and the sliding sleeve 1073 are both provided with anti-slip patterns, and the anti-slip patterns are arc-shaped convex edges.

[0034] The anti-slip pattern increases the surface friction resistance of the adjustment knob 505 and the sliding sleeve 1073, thereby improving the convenience of knob adjustment.

[0035] Furthermore, the base 107 includes a support plate 1071, a support rod 1072, a sliding sleeve 1073, a sliding rod 1074, a locking bolt 1075 and a support frame 1076. The support rod 1072 is fixedly installed on the upper end surface of the support plate 1071, the top of the support rod 1072 is rotatably connected to the support frame 1076, the bottom of the sliding sleeve 1073 is rotatably connected to the support plate 1071, the sliding rod 1074 is inserted into the sliding sleeve 1073 and slidably connected thereto, the top of the sliding rod 1074 is rotatably connected to the support frame 1076, and the locking bolt 1075 is installed on the sliding sleeve 1073 to squeeze and fix the sliding rod 1074.

[0036] By adjusting the extension length of the slide rod 1074, the pitch angle of the delivery pipe 101 is adjusted to change the residence time of the capsule in the delivery pipe 101, ensuring that the capsule can be fully polished, thereby meeting the polishing requirements of capsules of different diameters and improving the application range of the equipment.

[0037] When the device is in use, check whether the various components of the polishing device are firmly installed, including the base 107, the feeding hopper 103, the feeding pipe 101, the polishing drum 104 and the driving motor 105 of the polishing machine body 1, and the dust collector 201, the first connecting pipe 202 and the suction hood 203 of the dust collection mechanism 2, etc., to ensure that there is no looseness or damage. Pour the capsule medicine to be polished from the feeding hopper 103, and the capsule first falls on the sliding screen plate 4. Due to the existence of the first screen plate 401 and the second screen plate 402, the capsule feeding speed is limited, and the medicine powder and the empty capsule shell will stay on the screen plate for a certain time; The driving motor 105 is started, and the motor drives the polishing drum 104 to rotate. The first spiral blade 1041 on the surface of the polishing drum 104 starts to drive the capsule particles to move from the feeding hopper 103 to the discharge pipe 1011. During the movement, the capsule contacts and rubs with the first spiral blade 1041 and the polishing bristles 1042 on the surface of the polishing drum 104, so that the polishing bristles 1042 sweep the powder on the surface of the capsule. At the same time, the vacuum cleaner 201 is started, and the vacuum cleaner 201 passes through the first connecting pipe 20 2 cooperates with the suction hood 203, and the second suction hole 10441 of the docking part 1044 and the first suction hole 1043 on the surface of the polishing drum 104 are used for suction, and the swept powder is sucked into the dust collector 201, so as to achieve the polishing of the capsule and the collection of dust. During the rotation of the polishing drum 104, the first tooth umbrella 1045, the second tooth umbrella 5011 and the third tooth umbrella 303 cooperate to drive the slag auger rod 3 to rotate in the opposite direction, and the slag auger rod 3 removes the inner wall of the polishing drum 104. The medicine powder adhering to moisture is scraped off and transported to the suction hood 203, and then sucked into the vacuum cleaner 201 through the airflow to keep the inside of the polishing drum 104 clean. When the driving motor 105 drives the polishing drum 104 to rotate, it also drives the transmission shaft 501 to rotate through the transmission mechanism 5, and then drives the eccentric shaft 503 at the top of the transmission shaft 501 to rotate. During the rotation of the eccentric shaft 503 around the transmission shaft 501, the sliding screen plate 4 is repeatedly pushed and pulled to make the sliding screen plate 4 shake, so as to avoid blockage caused by accumulation of capsules. , ensuring smooth material feeding and continuity of the polishing process. When the vacuum cleaner 201 inhales air, the air flow velocity increases due to the reduction in aperture at the contraction section 20321 of the suction pipe 2032, thereby forming a negative pressure at the negative pressure suction hole 20323, and suction is performed by the suction chamber 1032. Since the empty capsule shells are light in weight and large in volume, the wind resistance is relatively large. The powder and empty capsule shells between the sliding screen plates 4 are affected by the airflow and are sucked into the vacuum cleaner 201 from the suction chamber 1032, reducing the subsequent polishing pressure. Example 2

[0038] See also Figure 1-Figure 11 A method for using a polishing device for capsule drug production and processing is applicable to a polishing device for capsule drug production and processing, comprising the following steps: Step 1, feeding. Before feeding, ensure that the feeding hopper 103 and its peripheral equipment are clean and free of impurities to avoid contamination of the capsule medicine. The operator slowly pours the capsule particles that have just been filled and have medicine powder attached to the surface into the feeding hopper 103. Note that the feeding speed should be moderate to avoid excessive accumulation of capsules in the feeding hopper 103 and overflow due to feeding too quickly, and prevent damage to the sliding screen plate 4 due to excessive impact; Step 2, preliminary screening. When the capsule particles enter the hopper 103, they first contact the sliding screen plate 4. The sliding screen plate 4 is composed of a first screen plate 401, a second screen plate 402 and a connecting plate 403. Its unique structural design can effectively perform preliminary screening on the material. There is a certain gap between the first screen plate 401 and the second screen plate 402, so that the medicine powder and the empty capsule shells have a certain residence time on the second screen plate. When the vacuum cleaner 201 inhales, the airflow speed increases due to the reduction of the aperture at the contraction section 20321 of the suction pipe 2032, thereby forming a negative pressure at the negative pressure suction hole 20323, and the suction is carried out by the suction chamber 1032. Since the empty capsule shell is light in weight and large in volume, the wind resistance is relatively large. The medicine powder and the empty capsule shell between the sliding screen plates 4 are affected by the airflow and are sucked into the vacuum cleaner 201 from the suction chamber 1032; Step 3, capsule polishing, start the drive motor 105, the motor operation drives the polishing drum 104 to start rotating. The outer end surface of the polishing drum 104 is provided with a first spiral blade 1041. During the rotation process, the first spiral blade 1041 not only plays a role in pushing the capsule to move along the feeding pipe 101 to the discharge pipe 1011, but also makes the capsule roll continuously during the movement, ensuring that each surface of the capsule can fully contact the polishing parts of the polishing drum 104. At the same time, the surface of the polishing drum 104 and the surface of the first spiral blade 1041 are provided with polishing bristles 1042. These bristles are soft and have good wear resistance and cleaning ability. When the capsule contacts the bristles, the bristles use the friction between them and the surface of the capsule to gradually sweep off the powder attached to the surface of the capsule, thereby achieving the polishing effect of the capsule. In addition, during the polishing process, the dust suction mechanism 2 works synchronously, and the dust collector 201 is connected with the suction hood 203 through the first connecting pipe 202. The suction hood 203 is sleeved on the polishing drum 104 and rotates with it. The polishing drum 104 is dynamically connected so that when the polishing drum 104 rotates, the suction hood 203 can always maintain effective connection and sealing with the drum. The surface of the polishing drum 104 is provided with a first suction hole 1043, and the docking part 1044 is provided with a second suction hole 10441. The vacuum cleaner 201 sucks the powder swept off during the polishing process into the vacuum cleaner 201 through the suction hole, effectively avoiding the flying and accumulation of the powder inside the equipment, not only ensuring the cleanliness of the working environment, but also preventing the secondary pollution of the powder, ensuring the polishing quality of the capsule, and, while the polishing drum 104 is rotating, the slag removal auger rod 3 is also working synchronously through the action of the transmission mechanism 5. The slag removal auger rod 3 is installed in the polishing drum 104 and is rotatably connected thereto, and includes a central axis 301 and a second spiral blade 302. The diameter of the second spiral blade 302 is equal to the inner diameter of the polishing drum 104 and can fit tightly against the inner wall of the drum. When the driving motor 105 drives the polishing drum 104 to rotate, the slag removal auger rod 3 rotates in the opposite direction through the cooperation of the first tooth umbrella 1045, the second tooth umbrella 5011 and the third tooth umbrella 303, and the powder attached to the inner wall of the polishing drum 104 due to moisture absorption and other reasons is scraped off and transported to the vicinity of the suction hood 203, and sucked into the dust collector 201 with the help of the airflow generated by the dust suction mechanism 2, thereby further ensuring the cleanliness of the interior of the polishing drum 104, avoiding blockage inside the polishing drum 104, and improving the polishing effect and quality stability of the capsule; Step 4, discharge. The capsules after polishing are continuously pushed by the first spiral blade 1041 of the polishing drum 104 and gradually move along the conveying pipe 101 toward the discharge pipe 1011. At the outlet of the discharge pipe 1011, a corresponding collection device, such as a clean material barrel or a conveying pipeline, can be connected to collect the polished capsules in an orderly manner for subsequent packaging or further processing.
