A pharmaceutical capsule polishing device

Abstract

This utility model discloses a pharmaceutical capsule polishing device, relating to the field of capsule polishing machine technology. It includes a base, a rotating shaft, and a spiral brush. A blower and two support plates are mounted on the top of the base. In this utility model, when the rotating shaft rotates for polishing, it drives a circular plate to rotate. The rotation of the circular plate, through an L-shaped plate, a fixed rod, and a connecting plate, causes a rack to reciprocate. This reciprocating movement of the rack, through a semi-circular gear, causes a ring block to reciprocate, which in turn causes a rotating rod to reciprocate. This allows the brush bristles to contact the sieve holes at different positions on the shell, avoiding dead angles and preventing localized blockages. Simultaneously, the reciprocating rotation of the ring block, through a circular gear and an arc-shaped rack, causes the rotating rod to rotate, further rotating and cleaning the sieve holes with the brush bristles, resulting in better cleaning. Furthermore, the rotation of the rotating rod ensures continuous contact and scraping between the scraper and the brush bristles, increasing the reusability of the brush bristles.

Description

Technical Field

[0001] This utility model relates to the field of capsule polishing machine technology, and in particular to a pharmaceutical capsule polishing device. Background Technology

[0002] Capsules generally refer to medications encapsulated in capsules. These are usually powders or granules that irritate the esophagus and gastric mucosa, or medications that have an unpleasant taste, are easily volatile, are easily broken down by saliva in the mouth, or are easily inhaled into the trachea. Capsules can be hard or soft, and during production, they require polishing equipment for polishing.

[0003] In the prior art, patent CN219562634U discloses a capsule polishing machine, which uses an upper shell, lower shell, support frame, funnel, slow plate, motor, rotating shaft, sliding groove, rotating groove, insertion rod, clamping block, sliding chamber, spring, limiting rod, limiting groove, spiral brush, snap-fit ​​plate, exhaust pipe, exhaust fan, discharge pipe, filter plate, fixing ring, limiting ring, and connecting ring to facilitate the replacement and cleaning of the spiral brush. However, when the dust generated by the exhaust fan and filter plate polishing is adsorbed, the filter plate is prone to clogging, affecting the dust collection efficiency. Another capsule polishing machine, CN222589252U, uses a cleaning brush for cleaning, but the filter plate of the polishing machine is mostly arc-shaped, which makes it difficult to cover all the sieve holes at the bottom of the shell during cleaning, easily forming cleaning dead corners and causing local clogging, which is inconvenient to use. In view of the shortcomings of the prior art, this utility model discloses a pharmaceutical capsule polishing device to solve the above problems. Utility Model Content

[0004] The purpose of this application is to provide a pharmaceutical capsule polishing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a pharmaceutical capsule polishing device, comprising a base, a rotating shaft, and a spiral brush. A fan and two support plates are mounted on the top of the base. A housing is mounted on the top of the two support plates. A motor, a funnel, and a discharge pipe are respectively mounted on the side, top, and bottom of the housing. The rotating shaft is rotatably mounted on the opposite inner walls of the housing. One end of the rotating shaft is mounted on the output shaft of the motor. Multiple sieve holes are fixed at the bottom of the housing. A cleaning and suction mechanism is provided on one of the support plates.

[0006] The cleaning and suction mechanism includes an annular block rotatably fitted onto the housing. One of the support plates has a fixing groove on its top that matches the annular block. The side of the annular block has a rotating hole, and a rotating rod is rotatably mounted on the rotating hole. The rotating rod has multiple bristles. One of the support plates has a clearance hole that matches the rotating rod. Another support plate has a drive suction assembly that allows the annular block and the rotating rod to rotate simultaneously. The drive suction assembly is installed in conjunction with the rotating shaft.

[0007] Preferably, the drive suction assembly includes a semi-annular gear mounted on the outer wall of the annular block, a slide rod mounted on the inner wall of the fixing groove, a spur rack slidably sleeved on the slide rod, the semi-annular gear meshing with the spur rack, an L-shaped plate mounted on the side of the spur rack, a moving hole adapted to the L-shaped plate being opened on the side of one of the support plates, the end of the rotating shaft away from the motor extending to the outside of the housing and mounted with a circular plate, a fixing rod eccentrically mounted on the side of the circular plate, a connecting plate rotatably sleeved on the fixing rod, the other end of the connecting plate rotatably mounted on the side of the L-shaped plate, a sealing box being mounted on the side of one of the support plates and the bottom of the housing, an installation hole being opened at the bottom of the sealing box, an air pipe being mounted on the output end of the exhaust fan and the installation hole, and a driven unit for rotating the rotating rod being provided on one of the support plates.

[0008] Preferably, the driven unit includes a circular gear mounted on one end of the rotating rod, and an arc-shaped rack is mounted on the side of one of the support plates, the circular gear and the arc-shaped rack meshing together.

[0009] Preferably, a striking plate is installed on the top of the L-shaped plate, and a fixing plate is installed on the side of the funnel.

[0010] Preferably, a scraper is installed on the side of the annular block.

[0011] Preferably, the side of the annular block is fitted with an incomplete annular sealing gasket.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, when the rotating shaft rotates for polishing, it drives the circular plate to rotate. The rotation of the circular plate causes the straight rack to move back and forth through the L-shaped plate, the fixed rod, and the connecting plate. The reciprocating movement of the straight rack causes the semi-circular gear to rotate back and forth. The reciprocating movement of the semi-circular gear causes the annular block to rotate back and forth, which in turn causes the rotating rod to move back and forth. This allows the brush bristles to contact the screen holes at different positions on the housing, avoiding dead angles that could cause local blockage. At the same time, when the annular block rotates back and forth, it causes the rotating rod to rotate through the circular gear and the arc-shaped rack, which in turn causes the brush bristles to rotate and clean the screen holes, resulting in a better cleaning effect.

[0014] 2. In this utility model, the rotation of the rotating rod allows the bristles to continuously contact the scraper, thereby scraping the bristles and increasing the reusability of the bristles. The setting of the striking plate and the fixing plate facilitates the vibration of the funnel while the L-shaped plate moves, thus preventing the capsule from becoming blocked in the funnel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] refer to Figure 1-6 The illustrated pharmaceutical capsule polishing device includes a base 1, a rotating shaft 5, and a spiral brush. It should be noted that in this embodiment, the installation method and usage method of the rotating shaft 5 and the spiral brush can refer to the technical content of a capsule polishing machine disclosed in Chinese Patent Publication No. CN219562634U, which will not be repeated here. The top of the base 1 is equipped with an exhaust fan and two support plates 2. The top of the two support plates 2 are jointly equipped with a housing 3. The side, top, and bottom of the housing 3 are respectively equipped with a motor 4, a funnel 20, and a discharge pipe. The rotating shaft 5 is rotatably mounted on the opposite inner wall of the housing 3. One end of the rotating shaft 5 is mounted on the output shaft of the motor 4. The bottom of the housing 3 is fixed with multiple sieve holes. One of the support plates 2 is equipped with a cleaning and suction mechanism.

[0026] The cleaning and suction mechanism includes an annular block 7 rotatably sleeved on the housing 3. One of the support plates 2 has a fixing groove on its top that matches the annular block 7. The side of the annular block 7 has a rotating hole. A rotating rod 8 is rotatably mounted on the rotating hole. The rotating rod 8 is provided with multiple bristles 9. One of the support plates 2 has a clearance hole that matches the rotating rod 8. Another support plate 2 has a drive suction assembly that allows the annular block 7 and the rotating rod 8 to rotate simultaneously. The drive suction assembly is installed in conjunction with the rotating shaft 5.

[0027] With the above structure, during use, the capsule is first placed on the funnel 20, and then the capsule will fall into the housing 3 under the action of gravity. At this time, the motor 4 is turned on, and the output of the motor 4 will cause the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will polish the capsule and move it through the spiral brush. At this time, the dust generated by polishing will fall through the screen holes and be sucked up by the exhaust fan. At the same time, the rotation of the rotating shaft 5 will drive the suction component to make the ring block 7 swing back and forth. The back and forth swing of the ring block 7 will cause the rotating rod 8 to move, so that the bristles 9 will contact the screen holes at different positions on the housing 3, avoiding dead corners and causing local blockage. Meanwhile, the movement of the rotating rod 8 will drive the suction component to rotate, which in turn will make the bristles 9 rotate, improving the cleaning effect.

[0028] like Figure 2 - Figure 6 As shown, the drive suction assembly includes a semi-annular gear 12 mounted on the outer wall of the annular block 7. A slide rod 13 is mounted on the inner wall of the fixing groove. A spur rack 14 is slidably sleeved on the slide rod 13. The semi-annular gear 12 meshes with the spur rack 14. An L-shaped plate 15 is mounted on the side of the spur rack 14. A moving hole adapted to the L-shaped plate 15 is opened on the side of one of the support plates 2. The end of the rotating shaft 5 away from the motor 4 extends to the outside of the housing 3 and is mounted with a circular plate 6. A fixing rod 22 is eccentrically mounted on the side of the circular plate 6. A connecting plate 2 is rotatably sleeved on the fixing rod 22. 3. The other end of the connecting plate 23 is rotatably mounted on the side of the L-shaped plate 15. A sealing box 21 is installed on the side of one of the support plates 2 and the bottom of the housing 3. The bottom of the sealing box 21 is provided with a mounting hole. An air pipe is installed on the output end of the exhaust fan and the mounting hole. A driven unit that makes the rotating rod 8 rotate is provided on one of the support plates 2. The advantage of this arrangement is that, through the arrangement of the circular plate 6, the semi-circular gear 12, the sliding rod 13, the straight rack 14, the L-shaped plate 15, the sealing box 21, the fixing rod 22, the connecting plate 23 and the air pipe, it is easy for the rotating shaft 5 to drive the annular block 7 to reciprocate.

[0029] Specifically, when the rotating shaft 5 rotates, the circular plate 6 rotates, which causes the fixed rod 22 to move eccentrically. The eccentric movement of the fixed rod 22 causes the L-shaped plate 15 to move back and forth through the connecting plate 23. The back and forth movement of the L-shaped plate 15 causes the rack 14 to move back and forth under the action of the sliding rod 13. The back and forth movement of the rack 14 causes the semi-circular gear 12 to rotate back and forth. The back and forth movement of the semi-circular gear 12 causes the annular block 7 to rotate back and forth, which in turn causes the rotating rod 8 to move back and forth. This allows the brush bristles 9 to contact the sieve holes at different positions on the housing 3, avoiding dead corners that could cause local blockages. At the same time, during cleaning, the exhaust fan is turned on, and the exhaust fan will suck up and collect the dust in the sealed box 21 through the air pipe.

[0030] like Figure 3 As shown, the driven unit includes a spur gear 10 installed at one end of the rotating rod 8, and an arc-shaped rack 11 is installed on the side of one of the support plates 2. The spur gear 10 and the arc-shaped rack 11 mesh with each other. The advantage of this arrangement is that the rotating rod 8 can be easily rotated by the arrangement of the spur gear 10 and the arc-shaped rack 11.

[0031] Specifically, when the annular block 7 reciprocates, the rotation of the annular block 7 causes the rotating rod 8 to move, the movement of the rotating rod 8 causes the circular gear 10 to move, and the movement of the circular gear 10 causes it to rotate under the action of the arc rack 11, which in turn causes the rotating rod 8 to rotate, thereby causing the brush bristles 9 to rotate and clean the sieve holes, resulting in a better cleaning effect.

[0032] like Figure 1 and Figure 2 As shown, a striking plate 16 is installed on the top of the L-shaped plate 15, and a fixing plate 17 is installed on the side of the funnel 20. The advantage of this arrangement is that the striking plate 16 and the fixing plate 17 facilitate the vibration of the funnel 20.

[0033] Specifically, the back-and-forth movement of the L-shaped plate 15 causes the striking plate 16 to move back and forth, which in turn strikes the fixed plate 17, causing the funnel 20 to vibrate and thus preventing the capsule from becoming blocked in the funnel 20.

[0034] like Figure 4 and Figure 5 As shown, a scraper 18 is installed on the side of the annular block 7. The advantage of this arrangement is that the scraper 18 makes it easier to scrape the bristles 9.

[0035] Specifically, when the rotating rod 8 rotates, the bristles 9 also rotate. At this time, the dust-covered bristles 9 rotate and will hit the scraper 18. Simultaneously, the scraper 18 will scrape the bristles 9, thereby increasing the reusability of the bristles 9.

[0036] like Figure 4 and Figure 5 As shown, an incomplete annular sealing gasket 19 is installed on the side of the annular block 7. The advantage of this setting is that the incomplete annular sealing gasket 19 can achieve a certain sealing effect.

[0037] Specifically, when the annular block 7 rotates, the incomplete annular sealing gasket 19 can block the gap between the clearance hole and the annular block 7, thereby reducing the escape of dust.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
