Description

Technical Field

[0001] The present invention relates to the field of traditional Chinese medicine packaging, and more particularly to a production device for aseptic packaging of traditional Chinese medicine powder. Background Art

[0002] In the field of traditional Chinese medicine preparation production, the encapsulation technology of traditional Chinese medicine powder is crucial to ensuring the quality and safety of drugs. Currently, most traditional Chinese medicine powders on the market are generally filled using traditional packaging equipment.

[0003] However, existing packaging equipment, before heat-sealing, creates gaps at the edges of the packaging tape during filling, allowing TCM powder to easily leak out. This not only wastes TCM powder and increases production costs, but also causes powder to adhere to the surfaces of equipment components, causing excessive wear. Furthermore, spilled TCM powder can easily mix with other batches of products, resulting in mixed packing. Summary of the Invention

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The specific embodiments of the present invention are described in detail below in conjunction with the drawings in the specification.

[0042] like Figures 10-17 As shown, a Chinese medicine powder aseptic packaging production device includes two symmetrically arranged mounting plates 32, a plurality of limit plates 56, two packaging belts 13 and a feeding pipe 4;

[0043] The outer walls of the two mounting plates 32 are rotatably connected to multiple synchronization shafts 51, and the ends of the synchronization shafts 51 are fixedly connected to the conveying wheels 52. A sealing belt 53 for transmission is sleeved between the conveying wheels 52 arranged on the same side. The inner and outer contact surfaces of the sealing belt 53 are both convex outward to form an arc structure.

[0044] The limiting plates 56 are respectively located between the two conveying wheels 52 arranged on the same side. The outer wall of the limiting plate 56 is provided with a limiting groove 57. The outer wall of the limiting plate 56 is fixedly connected to a connecting rod 58. The end of the connecting rod 58 is fixedly connected to the mounting plate 32.

[0045] The outer wall of the packaging belt 13 is provided with an arc groove for storing materials; the top of the feeding pipe 4 is connected to the feeding machine discharge pipe and is sealed. The cross section of the feeding pipe 4 is a symmetrical closed curve with narrow ends and wide middle. The tips of the two ends are arc-tip structures, and a channel frame is formed between the outer and inner contours. The middle is a hollow area. The two ends of the feeding pipe 4 are symmetrically provided with arc-shaped fitting grooves 5. The two ends of the feeding pipe 4 extend between the two sealing belts 53 on the same side, and a sealing gap 59 is formed between the sealing belts 53.

[0046] The two packaging belts 13 rotate synchronously with multiple sealing belts 53. The edges on both sides of the packaging belts 13 pass through the sealing gap 59 and move downward along the outer wall of the feeding pipe 4. When the synchronous shaft 51 drives the sealing belt 53 to rotate through the conveying wheel 52, the sealing belt 53 slides along the inner wall of the limiting groove 57, so that the distance between the two sealing belts 53 on the same side is the same, and then the packaging belt 13 attached to the outer wall of the feeding pipe 4 is evenly squeezed into the bonding groove 5, so that a seal is formed between the feeding pipe 4 and the packaging belts 13 on both sides.

[0047] The arc-shaped structure of the sealing belt 53 and its cooperation with the limiting groove 57 can evenly squeeze the packaging belt 13, so that it fits tightly with the feeding tube 4 to form a seal, effectively preventing the Chinese medicine powder from diffusing from the gap; the limiting plate 56 and the limiting groove 57 limit and guide the movement of the sealing belt 53 to ensure the stability of the sealing process; the structure of the feeding tube 4 and the design of the fitting groove 5 facilitate cooperation with the packaging belt 13 to achieve sealed filling, solving the problem of powder leakage in traditional packaging equipment.

[0048] The outer walls of the two upper synchronous shafts 51 on the same mounting plate 32 are fixedly connected to the third driving gears 54, and the two third driving gears 54 are meshed with each other. The outer walls of multiple synchronous shafts 51 are fixedly connected to synchronous wheels 55. The two synchronous wheels 55 located at the upper and lower positions on the same mounting plate 32 are connected by a synchronous belt transmission. The outer walls of the two mounting plates 32 are fixedly connected to the fourth stepping motor 33, and the output ends of the fourth stepping motor 33 are respectively fixedly connected to the corresponding synchronous shafts 51.

[0049] Traditional equipment relies on static sealing strips or simple roller pressing, which can easily lead to powder leakage through gaps due to wear or uneven pressure. In this device, the feeding tube 4 adopts a symmetrical closed curve design with tapered ends, which is matched with the arc-shaped fitting groove 5 and adapts to the packaging belt 13. The arc-shaped raised sealing belt 53 rotates at a constant speed under the guidance of the limiting groove 57, dynamically maintaining a constant gap and evenly squeezing the packaging belt into the fitting groove, achieving a dynamic seal and preventing powder leakage.

[0050] In this embodiment, Figure 1 As shown, the aseptic packaging production device for traditional Chinese medicine powder also includes a chassis 1, the outer wall of the chassis 1 is hinged with a box door 2, the inner wall of the box door 2 is fixedly connected to a transparent glass 30, an ultraviolet sterilization lamp 9 is installed at the bottom of the inner wall of the chassis 1, the top of the feeding pipe 4 passes through the chassis 1 and extends to its outside, the feeding pipe 4 is fixedly connected to the chassis 1, and the inner wall of the chassis 1 is detachably fixedly connected to a first support plate 6, one of the mounting plates 32 is fixedly connected to the inner wall of the chassis 1, and the other mounting plate 32 is fixedly connected to the first support plate 6.

[0051] The ultraviolet sterilization lamp 9 sterilizes the inside of the chassis 1 to ensure a sterile environment during the packaging process of the traditional Chinese medicine powder and improve product quality; the setting of the first support plate 6 facilitates the fixation and installation of the mounting plate 32, making the device structure more stable.

[0052] In this embodiment, as 1 and Figure 2 As shown, the inner wall of the chassis 1 is detachably fixedly connected with the second support plate 7, and the outer walls of the first support plate 6 and the second support plate 7 are detachably connected to the two rotating shafts 10, the rotating shaft 10 on the first support plate 6 corresponds to the upper part of the rotating shaft 10 on the second support plate 7, and the ends of the rotating shafts 10 are respectively rotatably connected to the chassis 1, and the outer walls of the two rotating shafts 10 at the top are detachably fixedly connected with the unwinding reel 11, and the outer walls of the two rotating shafts 10 at the bottom are detachably fixedly connected with the receiving reel 12, and the outer wall of the chassis 1 is fixedly connected with multiple first stepper motors 3, and the output ends of the first stepper motors 3 are respectively fixedly connected to the corresponding rotating shafts 10, and two packaging belts 13 are wound around the corresponding unwinding reels 11, and the packaging belts 13 are released by rotating the unwinding reel 11, and the waste left by the slitting of the packaging belts 13 is respectively wound around the corresponding receiving reels 12, and the waste left by the slitting is wound up by rotating the receiving reel 12.

[0053] The unwinding reel 11 and the rewinding reel 12 are used for releasing the packaging tape 13 and winding the waste material respectively. The first stepper motor 3 accurately controls the rotation of the rotating shaft 10 to achieve uniform release of the packaging tape 13 and orderly winding of the waste material, thereby ensuring the continuity of the production process.

[0054] Conventional equipment often causes packaging misalignment or sealing failure due to asynchronous conveying. In this device, the packaging belt 13 is conveyed through the conveying hole 14 in meshing engagement with the first gear ring 23, avoiding slippage and deviation, which can improve packaging accuracy and sealing effect.

[0055] In this embodiment, as 1- Figure 6As shown, a plurality of conveying holes 14 are provided on the edges of both sides of the packaging belt 13, and two second drive shafts 20 are rotatably connected between the first support plate 6 and the chassis 1. The outer walls of the second drive shafts 20 are fixedly connected with connecting sleeves 21, and the tops of the two mounting plates 32 are bent to form bending portions 50. The ends of the bending portions 50 are respectively fixedly connected to the corresponding connecting sleeves 21, and both ends of the connecting sleeves 21 are rotatably connected with rotating wheels 22. The outer walls of the rotating wheels 22 are rotatably connected to the first gear ring 23, and the first gear ring 23 is engaged with the conveying holes 14 on the packaging belt 13.

The chassis 1 and the outer walls of the first support plate 6 are fixedly connected with third stepper motors 31, and the output ends of the two third stepper motors 31 are respectively fixedly connected to the corresponding second drive shafts 20.

[0056] The conveying hole 14 on the packaging belt 13 cooperates with the first gear ring 23, the guide gear 19, etc. to achieve accurate conveying of the packaging belt 13 and prevent the packaging belt 13 from deflecting or slipping during the conveying process.

[0060] The heat sealing wheel 27 performs heat pressure sealing on the side of the packaging belt 13 to effectively prevent the powder from leaking.

[0063] In this embodiment, as 2, Figure 3 、 Figure 7 、 Figure 8 and Figure 9 As shown, the inner wall of the chassis 1 is fixedly connected to a roller conveyor 8, and the unloading section of the roller conveyor 8 extends to the outside of the chassis 1. A third support plate 35 is fixedly connected between the two mounting plates 32, and a cylinder 36 is fixedly connected to the outer wall of the third support plate 35. The output end of the cylinder 36 passes through the third support plate 35 and extends to its outside. The inner wall of the third support plate 35 is slidably connected to two guide rods 37.

The outer wall of the knife holder 38 is detachably fixedly connected to a slitting knife 39. The roller conveyor 8 is located below the slitting knife 39, and both sides of the slitting knife 39 are fixedly connected. A slider 43 and a bracket 40 are provided between the two mounting plates 32. The inner walls on both sides of the bracket 40 are fixedly connected with slide rods 41. The outer walls of the slide rods 41 are sleeved with springs 42. The slide rods 41 pass through the slider 43 and are slidably connected thereto. Both ends of the spring 42 are fixedly connected to the slider 43 and the bracket 40 respectively.

Two rubber plates 46 are fixedly connected to the side of the support plate 45 close to the packaging belt 13.

[0071] During the conveying process of the packaging belt 13, it moves downward along both sides of the feeding pipe 4, and the third stepper motor 31 is started. Under the connection of the transparent glass 30 and the synchronous belt, the two second drive shafts 20 rotate synchronously in opposite directions. The second drive shaft 20 drives the second ring gear 24 to rotate through the connecting sleeve 21, and the second ring gear 24 drives the first driven gear 26 to rotate through the second driven gear 29, thereby driving the heat sealing wheel 27 to rotate. The heat sealing wheel 27 is used to squeeze the side edges of the two packaging belts 13 together for heat sealing. At the same time, the heat sealing wheel 27 can convey the packaging belt 13 downward, so that the packaging belt 13 can fit the outer wall of the feeding pipe 4 and move downward.

[0072] After heat sealing, the two packaging belts 13 are easily connected to each other to form a bag structure, and thus enter between two adjacent sealing belts 53 for transportation. The fourth stepper motor 33 drives the synchronous shaft 51 to rotate, and the conveying wheel 52 rotates accordingly, causing the sealing belt 53 to slide along the inner wall of the limiting groove 57.

[0073] During the rotation process, the sealing belt 53 squeezes the packaging belt 13 attached to the outer wall of the feeding tube 4 into the fitting groove 5. Under the limitation of the limiting plate 56, the sealing belt 53 can stably clamp the packaging belt 13, tighten the packaging belt 13, and fit tightly with the outer wall of the feeding tube 4, so that a seal is achieved between the feeding tube 4 and the packaging belt 13. At the same time, the sealing belt 53 can move synchronously with the packaging belt 13. At this time, the Chinese medicine powder is filled into the arc groove of the packaging belt 13 through the hollow area in the middle of the feeding tube 4.

[0074] After the filling is completed, the packaging belt 13 continues to move downward. When the packaging belt 13 is transported to the cutting position, the cylinder 36 is started, pushing the slitting knife 39 and the bracket 40 to move. The bracket 40 squeezes the packaging belt 13 onto the rubber plate 46 through the heat sealing plate 44, and seals the filled packaging belt 13 through the heat sealing plate 44. Since there is a gap between the two heat sealing plates 44, there are two seals at this time. The slitting knife 39 drives the slider 43 to slide along the slide rod 41, so that the spring 42 is compressed, and the slitting knife 39 continues to move. Due to the squeezing of the two heat sealing plates 44, the packaging belt 13 between the two heat sealing plates 44 is in a taut state. The packaging belt 13 is cut by the slitting knife 39, and the cut is located between the two seals.

[0075] The fifth stepper motor 34 is activated, driving the two third drive shafts 47 to rotate. The third drive shafts 47 drive the corresponding disc cutters 48 to cut the packaging strip 13. The cut is located outside the heat-sealed area of ​​the heat-sealing wheel 27, allowing the packaging strip 13 to be separated after being cut. At the same time, the cut of the disc cutter 48 is connected to the cut of the slitting knife 39, causing the finished drug packages to fall from the packaging strip 13 onto the roller conveyor 8 and be transported out. The waste material on both sides of the separated packaging strip 13 is reeled up by the rotating take-up reel 12. Throughout the production process, the ultraviolet sterilization lamp 9 inside the chassis 1 can sterilize the interior of the chassis 1 before and after the equipment is operated, ensuring a sterile production environment.
