Description

Technical Field

[0001] This invention relates to the field of pharmaceutical powder filling equipment technology, specifically to a filling machine. Background Technology

[0002] The prepared powdered medicine needs to be dispensed into different medicine bottles using a filling machine. The filling machine is set up on an assembly line, which continuously feeds clean medicine bottles to the filling machine. After being filled by the filling machine, the medicine bottles are sent away again on the assembly line.

[0003] In the prior art, the structure of the filling machine can refer to a variable powder batch filling equipment and method disclosed in CN118907506A. The filling machine has a circular turntable with multiple receiving slots on its outer circumference. Medicine bottles on the production line enter the receiving slots as they pass the turntable, and then, as the turntable rotates, the medicine bottles are delivered to the bottom of the filling assembly of the filling machine. A valve is installed below the filling assembly to control the start and end of the flow of powder medicine to the medicine bottles below.

[0004] In practice, it has been found that there is a certain distance between the filling component of the filling machine and the medicine bottle below. The powder medicine flowing downward from the filling component can easily escape from this point. Some of the escaped powder medicine accumulates on the turntable, and some of the powder medicine accumulates under the medicine bottle. This makes it easy for a large amount of powder medicine to adhere to the body and bottom of the medicine bottle, resulting in the label not adhering firmly and the label easily falling off when the medicine bottle is labeled later.

[0060] See Figures 1 to 7 This embodiment provides a filling machine, including a machine base 10, a first arc plate 20, an annular feeding plate 11, a support mechanism 30, a drive mechanism, and a filling mechanism 40.

[0061] The first arc-shaped plate 20 is fixedly mounted on the machine base 10. The annular feeding plate 11 is rotatably mounted on the machine base 10, and the axis of the annular feeding plate 11 is also its rotation center line. The axis of the annular feeding plate 11 passes through the center of the first arc-shaped plate 20. Multiple recesses on the outer peripheral wall of the annular feeding plate 11 form receiving grooves 21. The receiving grooves 21 and the inner wall of the first arc-shaped plate 20 can form a receiving cavity 22 for receiving medicine bottles.

[0062] The support mechanism 30 is used to support the medicine bottles in the receiving cavity 22. The drive mechanism is used to drive the annular feed plate 11 to rotate. The filling mechanism 40 is mounted on the machine base 10 and is used to fill the medicine bottles in the receiving cavity 22 with powdered medicine. The filling mechanism 40 adopts existing technology and will not be described in detail here.

[0063] In this embodiment, by setting an annular feeding plate 11 instead of the turntable structure in the prior art, the accumulation of powdered medicine can be reduced, thereby reducing the amount of powdered medicine adhering to the body of the medicine bottle, which is conducive to the subsequent labeling.

[0064] In one embodiment, the bottom of the receiving slot 21 has a through cleaning window 23.

[0065] The filling machine also includes a second arc plate 50 and brushes (brushes not shown).

[0066] The second arc-shaped plate 50 is mounted on the machine base 10. Specifically, the second arc-shaped plate 50 is connected to the first arc-shaped plate 20 via a connecting plate. The second arc-shaped plate 50 is located inside the annular feed plate 11, and the circle of the second arc-shaped plate 50 is located on the axis of the annular feed plate 11. The bristles are on the outer wall of the second arc-shaped plate 50, and the bristles can pass through the cleaning window 23 to contact the medicine bottles in the receiving groove 21. Specifically, the outer wall of the second arc-shaped plate 50 is densely covered with a large number of bristles.

[0067] In this embodiment, during the rotation of the annular feeding plate 11, the medicine bottle in the receiving groove 21 rotates together, and when the medicine bottle passes through the brush bristles, the powder medicine adhering to the bottle body can be brushed off by the brush bristles.

[0068] In one embodiment, the drive mechanism includes a rotary column 60, which is rotatably mounted on the machine base 10 and located within the annular feed plate 11. The drive mechanism also includes a motor, which is mounted within the machine base 10, and the output end of the motor is coaxially connected to the rotary column 60.

[0069] The support mechanism 30 includes a support component 31, multiple rotating shafts 32, multiple support blocks 33, multiple gears 34, and a third arc plate 35.

[0070] Support assembly 31 is connected to rotary column 60. Multiple rotating shafts 32 are located below annular feed plate 11, corresponding to receiving groove 21, and rotatably connected to support assembly 31. Multiple support blocks 33 are located below annular feed plate 11, corresponding one-to-one with rotating shaft 32, and connected to the upper end of the corresponding rotating shaft 32. Support blocks 33 are used to support medicine bottles in receiving groove 21. Gears 34 correspond one-to-one with rotating shaft 32, and coaxially connected to the lower end of rotating shaft 32. Third arc plate 35 is set on machine base 10, located below first arc plate 20, and rack 36 is provided on the inner wall of third arc plate 35. When gear 34 meshes with rack 36, rotating shaft 32 rotates. Specifically, rack 36 has more than one section and is laid along the length of third arc plate 35. The rack 36 can be installed on the inner wall of the third arc plate 35 below the filling mechanism 40.

[0071] In this embodiment, the filling assembly fills the medicine bottle in the receiving groove 21 with powder medicine from above the annular feeding plate 11. The rotating column 60 drives multiple rotating shafts 32 to rotate through the support assembly 31. When the gear 34 below the rotating shaft 32 meshes with the rack 36 on the third arc plate 35, the rotating shaft 32 rotates, which in turn drives the medicine bottle to rotate through the support block 33. The rotating medicine bottle comes into contact with the bristles on the second arc plate 50, so that the bristles can clean the body of the medicine bottle around its circumference.

[0072] In one embodiment, the support component 31 includes a plurality of support rods 311.

[0073] Multiple support rods 311 are connected to the rotating column 60, and each support rod 311 corresponds to a rotating shaft 32. A drive hole 312 is provided on the end of the support rod 311 away from the rotating column 60. The rotating shaft 32 is threadedly connected to the drive hole 312. The lower end of the support block 33 abuts against the support rod 311.

[0074] In this embodiment, since the rotating shaft 32 is threadedly connected to the drive hole 312, as the rotating column 60 drives the rotating shaft 32 to rotate via the support rod 311, the gear 34 at the lower end of the rotating shaft 32 meshes with the rack 36, causing the rotating shaft 32 to rise as it rotates. This allows the medicine bottle above the support block 33 to rotate and rise simultaneously. The support block 33 can be made of rubber, allowing it to smoothly drive the medicine bottle on it to rotate.

[0075] As the medicine bottle rises during rotation, the parts of the bottle that are blocked by the cleaning windows 23 on the top and bottom can be exposed, allowing the bristles to clean the entire side of the bottle.

[0076] In one embodiment, the diameter of the upper end face of the support block 33 is smaller than the diameter of the bottom of the medicine bottle on it. Since the support block 33 is smaller than the bottom of the medicine bottle, powdered medicine falling from above will not accumulate on the support block 33, thereby preventing the bottom of the medicine bottle from being adhered to by medicine powder.

[0077] In one embodiment, the two ends of the first arc-shaped plate 20 are the feed end and the discharge end, respectively. The outer wall of the rotary column 60 is provided with mounting square holes 61 evenly distributed circumferentially.

[0078] The support assembly 31 also includes a limiting ring 313 and multiple springs 314.

[0079] A limiting ring 313 is mounted on the machine base 10 and surrounds the rotating column 60. Multiple springs 314 are correspondingly installed in the mounting square holes 61. The end of the support rod 311 away from the rotating shaft 32 is slidably inserted into the mounting square hole 61; the two ends of the springs 314 abut against the bottom of the mounting square hole 61 and the end of the support rod 311, respectively; the end of the support rod 311 away from the springs 314 abuts against the inner wall of the limiting ring 313; the limiting ring 313 is recessed at the feed end and discharge end of the first arc-shaped plate 20 to form clearance grooves 315; the two clearance grooves 315 are used to make way for the conveyor belts on both sides.

[0080] In this embodiment, medicine bottles are transported by conveyor belts located at the inlet and outlet ends of the first arc-shaped plate 20. The conveyor belt at the inlet end of the first arc-shaped plate 20 needs to transport the medicine bottles into the receiving groove 21, requiring it to enter the projection of the annular feeding plate 11 (viewed from above, the conveyor belt partially enters the annular feeding plate 11). Similarly, the conveyor belt at the outlet end of the first arc-shaped plate 20 does the same. Therefore, both sides of the limiting ring 313 are recessed to form clearance grooves 315 to accommodate the ends of the conveyor belts on both sides. Under the action of the spring 314, the end of the support rod 311 always abuts against the inner wall of the limiting ring 313. The end of the support rod 311 can be provided with a ball head or an arc surface to facilitate movement on the inner wall of the limiting ring 313.

[0081] In one embodiment, a feed transition plate 70 is connected to the inner wall of the feed end of the first arc-shaped plate 20; a discharge transition plate 71 is connected to the inner wall of the discharge end of the first arc-shaped plate 20; the feed transition plate 70 is used to receive medicine bottles conveyed by the conveyor belt; the discharge transition plate 71 is used to receive medicine bottles conveyed onto the conveyor belt from the support plate. The support block 33 is movable and docks with the feed transition plate 70 and the discharge transition plate 71 from the side; the upper end surface of the support block 33 is flush with the upper end surface of the feed transition plate 70 and the upper end surface of the discharge transition plate 71.

[0082] In this embodiment, due to the provision of the feeding transition plate 70 and the discharging transition plate 71, there is a transition process when the medicine bottle moves from the conveyor to the corresponding support block 33, or when the medicine bottle moves from the support block 33 to the conveyor. This allows the inner wall of the clearance groove 315 of the limiting ring 313 to transition more smoothly, thus making the support rod 311 move more smoothly against the inner wall of the limiting ring 313.

[0083] In addition, the machine base 10 is also equipped with arc-shaped guide blocks 80. Two arc-shaped guide blocks 80 can be provided, and the two arc-shaped guide blocks 80 are located on the upper and lower sides of the annular feeding plate 11, respectively. Figure 1 The two arc-shaped guide blocks 80 can work with the conveyor belt at the discharge end of the first arc-shaped plate 20 to guide the medicine bottles in the receiving tank 21 onto the conveyor belt.

[0084] The two conveyor belts corresponding to the discharge end and the feed end of the first arc plate 20 are both set on the machine base 10, and the two arc guide blocks 80 are connected to the machine base 10 by connecting with the conveyor belts.

In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
