Description

Technical Field

[0001] This utility model relates to the field of capsule production, specifically a powder removal device for capsules. Background Technology

[0002] During the filling process, capsules may contain some internal medicinal powder, resulting in dust covering the capsule surface. This affects the smoothness of the capsule surface, impacting the patient's experience when taking the medication. Furthermore, the powder may deteriorate, affecting the medication's effectiveness. Therefore, the surface of the filled capsules is typically polished to remove the dust. Current dust removal methods involve using a rotating brush to clean the capsule surface, separating the dust from the capsule, and then using a vacuum cleaner to remove the separated dust. This effectively removes dust from the capsule surface. However, this method leads to dust easily accumulating on the brush, requiring disassembly and cleaning or replacement after a period of use. This results in frequent and labor-intensive maintenance of the dust removal device, affecting its ease of use in the long run. Utility Model Content

[0003] The purpose of this invention is to provide a powder removal device for capsules, which can solve the technical problem that existing powder removal devices require frequent disassembly and cleaning. After use, the powder removal rod is moved downwards to contact the rotating spiral brush, and the dust on the brush is shaken off and sucked away by the vacuum pipe. It does not need to be disassembled for cleaning, which reduces the workload of cleaning and maintenance and greatly improves the convenience of cleaning after use.

[0004] To achieve the above objectives, this utility model employs the following technical solution: A powder removal device for capsules includes a powder removal cylinder with a support at the bottom and a powder removal chamber inside. The top and bottom of the powder removal cylinder are respectively provided with an inlet and an outlet communicating with the powder removal chamber. A rotating shaft is rotatably connected inside the powder removal chamber, and a spiral brush is mounted on the rotating shaft. A powder drop hole is provided at the bottom of the powder removal chamber, and a lower dust collection chamber communicating with the powder drop hole is provided at the bottom of the powder removal cylinder. A vacuum cleaner is located below the powder removal cylinder, and a lower suction pipe communicating with the lower dust collection chamber is provided on the vacuum cleaner. A powder cleaning rod is slidably connected vertically inside the powder removal chamber. After sliding downwards, the powder cleaning rod contacts the spiral brush. An upper dust collection chamber is provided inside the powder cleaning rod, and multiple suction nozzles communicating with the upper dust collection chamber are provided on the powder cleaning rod. An upper suction pipe communicating with the upper dust collection chamber is provided on the vacuum cleaner. An operating rod for controlling the vertical movement of the powder cleaning rod is provided on the powder removal cylinder.

[0005] Furthermore, the powder removal rod is symmetrically provided with guide posts, which penetrate the top of the powder removal chamber and are slidably connected thereto.

[0006] Furthermore, the top of the dust removal cylinder is provided with a fixed frame, the operating rod passes through the fixed frame and is threadedly connected to it, and the bottom end of the operating rod passes through the side wall of the dust removal chamber and is rotatably connected to the dust cleaning rod.

[0007] Furthermore, the bottom end of the powder cleaning rod is provided with multiple rubber protrusions, which are in contact with the spiral brush.

[0008] Furthermore, the suction nozzle is located between two adjacent rubber protrusions.

[0009] Furthermore, the top of the powder removal chamber is provided with a hidden groove, and the powder cleaning rod slides upward and enters the hidden groove.

[0010] Furthermore, a feed hopper is provided at the feed inlet, and an inclined discharge plate is provided below the discharge outlet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The structure of this utility model features a rotating shaft inside the dust removal chamber, on which a spiral brush is mounted. Dust-laden capsules enter the dust removal chamber through the feed inlet and come into contact with the rotating spiral brush, causing the dust on the capsule surface to be brushed off and separated from the capsule. The dust then enters the lower dust collection chamber through the bottom dust drop hole and into the vacuum cleaner through the lower dust collection pipe, achieving effective separation of dust and capsules. The capsules move towards the discharge outlet under the action of the spiral brush, allowing the clean capsules and dust to fall off separately, achieving effective polishing and dust removal of the capsule surface. Simultaneously, a cleaning rod is vertically slidably connected inside the dust removal chamber. After use, the cleaning rod is moved downwards, causing the rotating spiral brush to contact the cleaning rod, shaking off the dust adhering to the spiral brush. This achieves automatic cleaning after use, eliminating the need to disassemble the dust removal cylinder, greatly reducing cleaning and maintenance workload and improving cleaning convenience. 2. The cleaning rod has an upper suction chamber inside, with multiple suction nozzles connected to it. The vacuum cleaner has an upper suction pipe connected to the upper suction chamber. The dust removal cylinder has a control lever to move the cleaning rod vertically. During cleaning, the control lever drives the cleaning rod downward, causing it to contact the rotating spiral brush. This shakes off the dust from the spiral brush, effectively cleaning it. During the shaking process, the multiple suction nozzles on the cleaning rod generate suction through the upper suction chamber and upper suction pipe, promptly removing the shaken dust and preventing it from re-adhering to the spiral brush. This simultaneous cleaning and vacuuming significantly improves cleaning efficiency, making the cleaning of the spiral brush more efficient and thorough. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0019] Reference Figure 1 and Figure 2This utility model describes a de-powdering device for capsules. The main structure includes a de-powdering cylinder 1, which is a circular cylindrical structure made of stainless steel or other metal materials. Its axial direction extends laterally. A support 2 is fixed to the bottom of the de-powdering cylinder 1 by welding or bolts, providing support for the cylinder. The de-powdering cylinder 1 has a de-powdering chamber 3 inside, where capsules undergo de-powdering treatment. The top and bottom of the de-powdering cylinder 1 are respectively provided with an inlet 4 and an outlet 5 communicating with the de-powdering chamber 3. Capsules enter the de-powdering chamber 3 through the inlet 4, and the de-powdered capsules are discharged from the outlet 5. A rotating shaft 6 is rotatably connected inside the de-powdering chamber 3 via bearings. The rotating shaft 6 is driven by a motor. Specifically, the output shaft of the motor and the rotating shaft 6 are equipped with... A meshing gear drives the rotation of the rotating shaft 6. A spiral brush 7 is fixed to the rotating shaft 6 by screws or integrally formed. The spiral brush 7 consists of spiral blades and bristles. The spiral blades are fixed to the side of the rotating shaft 6 by bolts or integrally formed, and the bristles are glued or snapped onto the surface of the spiral blades. It is generally made of nylon or polyester. With this structure, when the rotating shaft 6 rotates, the rotating spiral brush 7 contacts the capsule, brushing off the dust from the capsule surface. Simultaneously, the spiral action drives the capsule towards the discharge port 5. The bottom of the dust removal chamber 3 has a dust collection hole 8, the size of which is smaller than the size of the capsule. The bottom of the dust removal cylinder 1 is fixed with a downward suction device communicating with the dust collection hole 8 by welding or bolts. The dust chamber 9 and the lower suction chamber 9 are made of metal and are inclined at one end. The dust separated from the capsule passes through the dust discharge hole 8 and enters the lower suction chamber 9, while the capsule remains in the dust removal chamber 3 and moves towards the discharge port 5 under the action of the spiral, realizing the separation of the capsule and the dust and their separate discharge. A vacuum cleaner 10 is provided below the dust removal cylinder 1. The vacuum cleaner 10 can adopt any vacuum cleaner structure with a vacuum fan available on the market. Specifically, the KEDWEI vacuum cleaner 10DL-1020 can be used. The vacuum cleaner 10 is provided with a lower suction pipe 11 that communicates with the lower suction chamber 9. This structure allows the dust entering the lower suction chamber 9 to enter the vacuum cleaner 10 along the inclined direction from the lower suction pipe 11, realizing the collection of dust and facilitating subsequent processing. For de-dusting or recycling, a cleaning rod 12 is vertically slidably connected inside the de-dusting chamber 3. The surface of the cleaning rod 12 is arc-shaped and covered with a rubber layer to prevent damage to the capsule when in contact with it, ensuring the integrity of the capsule. After the cleaning rod 12 slides downward, it contacts the spiral brush 7. With this structure, when de-dusting the capsule, the cleaning rod 12 slides upward so that the spiral brush 7 does not contact the cleaning rod 12 when rotating. When cleaning the spiral brush 7 is required after de-dusting, the cleaning rod 12 slides downward so that the rotating shaft 6 drives the spiral brush 7 to rotate, allowing the spiral brush 7 to contact the cleaning rod 12. This causes the dust adhering to the spiral brush 7 to be shaken off through collision. The cleaning rod 12 has an upper suction chamber 13 inside.The cleaning rod 12 is equipped with multiple suction nozzles 14 that communicate with the upper suction chamber 13. The suction nozzles 14 are located at the bottom of the cleaning rod 12. The vacuum cleaner 10 is equipped with an upper suction pipe 15 that communicates with the upper suction chamber 13. This structure allows the multiple suction nozzles 14 on the cleaning rod 12 to generate suction, sucking away the dust shaken off the spiral brush 7 through the suction nozzles 14 and into the vacuum cleaner 10 through the upper suction pipe 15. This achieves simultaneous cleaning and vacuuming, preventing the shaken dust from re-adhering to the spiral brush 7, thereby ensuring the smooth operation of the spiral brush. The brush 7 provides more efficient and thorough cleaning, eliminating the need to disassemble the de-dust removal cylinder 1, significantly reducing workload and improving efficiency and convenience. The de-dust removal cylinder 1 is equipped with an operating lever 16 that controls the vertical movement of the cleaning rod 12. The operating lever 16 drives the cleaning rod 12 to slide up and down. When de-dusturing the capsules, the cleaning rod 12 slides upwards to separate from the spiral brush 7. When cleaning the spiral brush 7, it slides downwards to bring the cleaning rod 12 into contact with the rotating spiral brush 7, making position adjustment of the cleaning rod 12 more convenient.

[0020] Preferably, guide posts 17 are symmetrically fixed to the powder removal rod 12 by welding or bolts. The guide posts 17 penetrate the top of the powder removal chamber 3 and are slidably connected to it. This structure allows the guide posts 17 on both sides to guide the vertical sliding of the powder removal rod 12 when the operating rod 16 makes vertical sliding adjustment of the position of the powder removal rod 12, so that the powder removal rod 12 remains in a horizontal state. This ensures that the spiral brush 7 can make full contact with the powder removal rod 12 at all positions, thereby improving the cleaning effect on all positions of the spiral brush 7 and making the cleaning of the spiral brush 7 more thorough and comprehensive.

[0021] Preferably, the top of the dust removal cylinder 1 is fixed with a fixing frame 18 by welding or bolts. The operating rod 16 passes through the fixing frame 18 and is threadedly connected to it. The bottom end of the operating rod 16 passes through the top of the dust removal chamber 3 and is rotatably connected to the dust removal rod 12 through a bearing. With this structure, the operating rod 16 can be rotated and moved downward under the action of the threaded connection. This causes the dust removal rod 12, which rotates at its bottom, to move up and down under the action of the guide posts 17 on both sides. The threaded connection allows the dust removal rod 12 to stop at the adjusted position, making the adjustment of the position of the dust removal rod 12 more convenient and the adjusted position more stable.

[0022] Preferably, the bottom end of the powder cleaning rod 12 is fixed with multiple rubber protrusions 19 by adhesive or bolts. The rubber protrusions 19 are in contact with the spiral brush 7. The setting of the rubber protrusions 19 can reduce the contact area with the spiral brush 7, increase the pressure at the contact position, improve the collision and shaking effect of dust, and at the same time, the elastic material of rubber can minimize the damage that may be caused when the capsule comes into contact with it, and ensure the integrity of the capsule.

[0023] Preferably, the suction nozzle 14 is located between two adjacent rubber protrusions 19. This structure allows the adjacent suction nozzle 14 to promptly remove the dust when the rubber protrusions 19 collide with the spiral brush 7 to shake off the dust. This makes the dust removal more timely, prevents the dust from sticking to other places, and makes the cleaning of the spiral brush 7 cleaner and more thorough.

[0024] Preferably, the top of the de-powdering chamber 3 is provided with a hidden groove 20, which is recessed inward from the top of the de-powdering chamber 3. The cleaning rod 12 slides upward and enters the hidden groove 20. After the cleaning rod 12 enters the hidden groove 20, it can seal the hidden groove 20. This structure allows the cleaning rod 12 to slide upward and enter the hidden groove 20 during the de-powdering process of the capsule, reducing the space occupied inside the de-powdering chamber 3. At the same time, it further reduces the contact area between the capsule and the cleaning rod 12, avoiding possible damage to the capsule and further ensuring the integrity of the capsule.

[0025] Preferably, a feeding hopper 21 is fixed to the feeding port 4 by welding or bolts. The feeding hopper 21 is wider at the top and narrower at the bottom, which can store a certain amount of capsules, making the feeding smoother and the number of capsules processed at one time greater. Below the discharging port 5, there is an inclined discharging plate 22, which is fixed to the side wall of the lower dust suction chamber 9 by welding or bolts, so that the capsules falling from the discharging port 5 can be discharged along the inclined discharging plate 22, making the discharge smoother.

[0026] Working Principle: This invention features a rotating shaft 6 inside the dust removal chamber 3, with a spiral brush 7 mounted on it. Dust-laden capsules enter the dust removal chamber 3 through the feed inlet 4 and come into contact with the rotating spiral brush 7. This brushes off the dust from the capsule surface, separating it from the capsule and allowing it to enter the lower suction chamber 9 through the dust drop hole 8 at the bottom. The dust then flows through the lower suction pipe 11 into the vacuum cleaner 10, effectively separating the dust from the capsule. Under the action of the spiral brush 7, the capsule moves towards the discharge port 5, allowing the clean capsule and dust to fall off separately, achieving effective polishing and dust removal of the capsule surface. Simultaneously, a cleaning rod 12 is vertically slidably connected inside the dust removal chamber 3. After use, the cleaning rod 12 is moved downwards, causing the rotating spiral brush 7 to contact it and shake off the dust adhering to the brush. This achieves automatic cleaning after use, eliminating the need to disassemble the dust removal cylinder 1, significantly reducing cleaning time. The maintenance workload is reduced, and the convenience of cleaning is improved. An upper suction chamber 13 is provided inside the dust removal rod 12, and multiple suction nozzles 14 connected to the upper suction chamber 13 are provided on the dust removal rod 12. An upper suction pipe 15 connected to the upper suction chamber 13 is provided on the vacuum cleaner 10. An operating lever 16 is provided on the dust removal cylinder 1 to control the vertical movement of the dust removal rod 12. With this structure, during cleaning, the operating lever 16 drives the dust removal rod 12 downwards, causing it to contact the rotating spiral brush 7, thereby shaking off the dust from the spiral brush 7 and effectively cleaning it. During the shaking process, the multiple suction nozzles 14 on the dust removal rod 12 generate suction through the upper suction chamber 13 and the upper suction pipe 15 connected to the vacuum cleaner 10, promptly sucking away the shaken dust and preventing it from re-adhering to the spiral brush 7. This allows for simultaneous cleaning and vacuuming, greatly improving cleaning efficiency and making the cleaning of the spiral brush 7 more efficient and thorough.
