Description

Technical Field

[0002] In the field of traditional Chinese medicine preparation production, the encapsulation technology of traditional Chinese medicine powder is crucial for ensuring the quality and safety of drugs. At present, during the filling process of most traditional Chinese medicine powders on the market, traditional packaging equipment is generally used for operation.

[0003] However, for the existing packaging equipment, during filling, since there are gaps at the edge joints of the packaging tape before hot pressing and sealing, it is extremely easy for the traditional Chinese medicine powder to diffuse out from these gaps. This situation will not only cause waste of traditional Chinese medicine powder, increase production costs, but also cause the powder to adhere to the surface of the parts on the equipment, resulting in excessive wear of the structure. At the same time, the spilled traditional Chinese medicine powder is also likely to be mixed into other batches of products, causing mis-packaging. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, this application proposes a sterile encapsulation production device for traditional Chinese medicine powder. Through the arc structure of the sealing tape and its cooperation with the limiting groove, the packaging tape can be evenly squeezed into the fitting groove of the feeding pipe to form a reliable seal, avoiding waste of traditional Chinese medicine powder, reducing production costs, and also reducing the wear of the powder on the equipment and the occurrence of mis-packaging phenomenon.

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0019] As Figures 10 - 17 shown, a sterile packaging production device for traditional Chinese medicine powder includes two symmetrically arranged mounting plates 32, a plurality of limiting plates 56, two packaging tapes 13 and a feeding pipe 4; A plurality of synchronous shafts 51 are rotatably connected to the outer walls of the two mounting plates 32. Conveyor wheels 52 are fixedly connected to the ends of the synchronous shafts 51. A sealing belt 53 for transmission is sleeved between the conveyor wheels 52 arranged up and down on the same side. The inner and outer contact surfaces of the sealing belt 53 bulge outwards to form an arc structure; The limiting plates 56 are respectively located between the two conveyor wheels 52 arranged up and down on the same side. A limiting groove 57 is formed on the outer wall of the limiting plate 56. A connecting rod 58 is fixedly connected to the outer wall of the limiting plate 56. The end of the connecting rod 58 is fixedly connected to the mounting plate 32; 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 pipe of the feeding machine and is sealed. The cross-section of the feeding pipe 4 is a symmetrically closed curve that is narrow at both ends and wide in the middle. The two pointed ends are arc-shaped tips. A channel border is formed between the outer contour and the inner contour, and the middle is a hollow area. Arc-shaped fitting grooves 5 are symmetrically provided at both ends of the feeding pipe 4. The two ends of the feeding pipe 4 respectively extend between two sealing belts 53 on the same side, and a sealing gap 59 is formed between the feeding pipe 4 and the sealing belts 53. The two packaging belts 13 and the multiple sealing belts 53 rotate synchronously. The two side edges of the packaging belt 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. Furthermore, the packaging belt 13 attached to the outer wall of the feeding pipe 4 is evenly squeezed into the fitting groove 5, so as to form a seal between the feeding pipe 4 and the two side packaging belts 13.

[0020] 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 pipe 4 to form a seal, effectively preventing the traditional Chinese medicine powder from diffusing through the gap; the limiting plate 56 and the limiting groove 57 limit and guide the movement of the sealing belt 53, ensuring the stability of the sealing process; the structure of the feeding pipe 4 and the design of the fitting groove 5 facilitate the cooperation with the packaging belt 13 to achieve sealed filling, solving the problem of powder leakage in traditional packaging equipment.

[0021] On the outer walls of the two synchronous shafts 51 located above on the same mounting plate 32, third driving gears 54 are fixedly connected. The two third driving gears 54 mesh with each other. Synchronous wheels 55 are fixedly connected to the outer walls of the multiple synchronous shafts 51. The two synchronous wheels 55 located at the upper and lower positions on the same mounting plate 32 are connected by synchronous belts. On the outer walls of the two mounting plates 32, fourth stepping motors 33 are fixedly connected. The output ends of the fourth stepping motors 33 are respectively fixedly connected to the corresponding synchronous shafts 51.

[0022] Traditional equipment relies on static sealing strips or simple roller pressing, which is prone to powder leakage through gaps due to wear or uneven pressure. In this device, the feeding pipe 4 adopts a symmetrically closed curve design that is narrow at both ends, and cooperates with the arc-shaped fitting groove 5 to adapt to the packaging belt 13; the arc-shaped protruding sealing belt 53 rotates at a constant speed under the guidance of the limiting groove 57, dynamically maintaining a constant distance, and evenly squeezing the packaging belt into the fitting groove to achieve dynamic sealing and prevent powder leakage.

[0023] In this embodiment, as Figure 1As shown in the figure, the aseptic packaging production device for traditional Chinese medicine powder also includes a chassis 1. A box door 2 is hinged to the outer wall of the chassis 1. A transparent glass 30 is fixedly connected to the inner wall of the box door 2. An ultraviolet germicidal lamp 9 is installed at the bottom of the inner wall of the chassis 1. The top of the feeding pipe 4 penetrates through the chassis 1 and extends to its outside. The feeding pipe 4 is fixedly connected to the chassis 1. A first support plate 6 is detachably and fixedly connected to the inner wall of the chassis 1. 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.

[0024] The ultraviolet germicidal lamp 9 sterilizes the inside of the chassis 1 to ensure a sterile environment during the packaging process of traditional Chinese medicine powder and improve product quality. The setting of the first support plate 6 facilitates the fixing and installation of the mounting plate 32, making the device structure more stable.

[0025] In this embodiment, as shown in Fig. 1 and Figure 2 As shown in the figure, a second support plate 7 is detachably and fixedly connected to the inner wall of the chassis 1. Two rotating shafts 10 are detachably and rotatably connected to the outer walls of the first support plate 6 and the second support plate 7. The rotating shafts 10 on the first support plate 6 are located above the corresponding rotating shafts 10 on the second support plate 7. The ends of the rotating shafts 10 are respectively rotatably connected to the chassis 1. Release reels 11 are detachably and fixedly connected to the outer walls of the two upper rotating shafts 10. Take-up reels 12 are detachably and fixedly connected to the outer walls of the two lower rotating shafts 10. A plurality of first stepping motors 3 are fixedly connected to the outer wall of the chassis 1. The output ends of the first stepping motors 3 are respectively fixedly connected to the corresponding rotating shafts 10. Two packaging tapes 13 are wound around the corresponding release reels 11, and the release reels 11 rotate to release the packaging tapes 13. The waste materials left after the packaging tapes 13 are slit are respectively wound around the corresponding take-up reels 12, and the take-up reels 12 rotate to wind up the waste materials left after slitting.

[0026] The release reels 11 and the take-up reels 12 are respectively used for the release of the packaging tapes 13 and the winding up of waste materials. The first stepping motors 3 precisely control the rotation of the rotating shafts 10 to achieve the uniform release of the packaging tapes 13 and the orderly winding up of waste materials, ensuring the continuity of the production process.

[0027] In traditional equipment, packaging misalignment or sealing failure often occurs due to asynchronous conveying. In this device, the packaging tape 13 is meshed and conveyed through the transmission holes 14 with the first gear ring 23, avoiding slipping and offset, and improving the packaging accuracy and sealing effect.

[0028] In this embodiment, as shown in Fig. 1 - Figure 6As shown in the figure, a plurality of conveying holes 14 are formed on both side edges of the packaging belt 13. There are two second drive shafts 20 rotatably connected between the first support plate 6 and the chassis 1. Connecting sleeves 21 are fixedly connected to the outer walls of the second drive shafts 20. Bent portions 50 are formed by bending the tops of the two mounting plates 32. The ends of the bent portions 50 are fixedly connected to the corresponding connecting sleeves 21 respectively. Rotating wheels 22 are rotatably connected to both ends of the connecting sleeve 21. First toothed rings 23 are rotatably connected to the circumferential outer walls of the rotating wheels 22. The first toothed rings 23 are engaged with the conveying holes 14 on the packaging belt 13. The released packaging belt 13 is conveyed by the rotation of the first toothed rings 23. Third stepping motors 31 are fixedly connected to the outer walls of the chassis 1 and the first support plate 6. The output ends of the two third stepping motors 31 are fixedly connected to the corresponding second drive shafts 20 respectively.

[0029] The conveying holes 14 on the packaging belt 13 cooperate with the first toothed rings 23, the guiding gears 19, etc. to realize the precise conveying of the packaging belt 13 and avoid phenomena such as deviation and slipping of the packaging belt 13 during the conveying process.

[0030] In this embodiment, as shown in FIGS. 1 and Figure 5 As shown in the figure, there are two first drive shafts 15 rotatably connected between the chassis 1 and the first support plate 6.

[0031] The first drive shafts 15, the first driving gears 16 and the second stepping motors 17 further enhance the stability and reliability of the conveying of the packaging belt 13. The first driving gears 16 are engaged with the first toothed rings 23 to drive the conveying of the packaging belt 13 and ensure that the packaging belt 13 remains stable during the conveying process.

The two heat sealing wheels 27 on the same side are used for thermally pressing and sealing the sides of the packaging belt 13.

[0033] The heat sealing wheels 27 perform thermally pressing and sealing on the sides of the packaging belt 13, effectively preventing the leakage of the powder.

Sliders 43 are fixedly connected to both sides of the cutting knife 39. A support 40 is arranged between the two mounting plates 32. Slide rods 41 are fixedly connected to the inner walls of both sides of the support 40. Springs 42 are sleeved on the outer walls of the slide rods 41. The slide rods 41 penetrate through the sliders 43 and are slidably connected to them. The two ends of the springs 42 are respectively fixedly connected to the sliders 43 and the support 40. Two heat-sealing plates 44 are fixedly connected to the side of the support 40 close to the packing belt 13.

Two rubber plates 46 are fixedly connected to the side of the support plate 45 close to the packing belt 13. A reserved groove is left between the two rubber plates 46 for the cutting knife 39 to extend into.

[0037] In this device, the heat-sealing wheel 27 first performs continuous heat-sealing on the sides to form a bag body; during cutting, the heat-sealing plates 44 pre-press the seal, and the cylinder 36 drives the cutting knife 39 to cut under the buffering of the spring 42, and the cut is located between the two seals; the circular knife 48 synchronously cuts the edge waste, and automatic winding is performed.

[0038] The roller conveyor 8 is used to convey the finished product of the cut packaging tape 13, facilitating subsequent collection and processing; the design of the air cylinder 36, the tool rest 38 and the cutting knife 39 can accurately and quickly cut the packaging tape 13; the slide bar 41, the spring 42 and the slider 43 play a buffering and guiding role, ensuring the smooth operation of the cutting knife 39 and extending the service life of the tool; the heat-sealing plate 44 heat-seals the cut packaging tape 13; the support plate 45 and the rubber plate 46 provide support and protection for the cutting process, ensuring the cutting quality.

The second stepping motor 17 drives the first drive shaft 15 to rotate, and the first driving gear 16 drives the first toothed ring 23 to rotate, so that the first toothed ring 23 conveys the released packaging tape 13 and conveys the packaging tape 13 between two adjacent heat-sealing wheels 27. During the conveying process of the packaging tape 13, the cut edge waste passes through the guide shaft 18, and the guide gear 19 on the guide shaft 18 meshes with the conveying hole 14 of the edge waste to guide the packaging tape 13.

[0043] During the conveying process of the packaging tape 13, it moves downward along both sides of the feeding pipe 4. The third stepping motor 31 is started. Under the connection of the transparent glass 30 and the synchronous belt, the two second drive shafts 20 rotate synchronously and in opposite directions. The second drive shafts 20 drive the second toothed rings 24 to rotate through the connecting sleeves 21. The second toothed rings 24 drive the first driven gears 26 to rotate respectively through the second driven gears 29, thereby driving the heat-sealing wheels 27 to rotate respectively. The two side edges of the packaging tape 13 are squeezed together by the heat-sealing wheels 27 for heat-sealing. At the same time, the heat-sealing wheels 27 can convey the packaging tape 13 downward, enabling the packaging tape 13 to move downward along the outer wall of the feeding pipe 4.

[0044] After heat sealing, the two packaging belts 13 are convenient to be connected to each other to form a bag structure, and thus enter between the adjacent two sealing belts 53 for conveying. The fourth stepping motor 33 drives the synchronous shaft 51 to rotate, and the conveying wheel 52 rotates accordingly, so that the sealing belt 53 slides along the inner wall of the limiting groove 57.

[0045] During the rotation of the sealing belt 53, the packaging belt 13 attached to the outer wall of the feeding pipe 4 is squeezed 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 tightly fit with the outer wall of the feeding pipe 4, so that the feeding pipe 4 and the packaging belt 13 are sealed. At the same time, the sealing belt 53 can move synchronously with the packaging belt 13. At this time, the traditional Chinese medicine powder is filled into the arc groove of the packaging belt 13 through the hollow area in the middle of the feeding pipe 4.

[0046] After the filling is completed, the packaging belt 13 continues to move downward. When the packaging belt 13 is conveyed to the cutting position, the air cylinder 36 is started to push the cutting knife 39 and the bracket 40 to move. The bracket 40 squeezes the packaging belt 13 on the rubber plate 46 through the heat sealing plate 44, and the filled packaging belt 13 is sealed 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 cutting knife 39 drives the slider 43 to slide along the slide bar 41, so that the spring 42 is compressed, realizing the continuous movement of the cutting knife 39. Due to the extrusion of the two heat sealing plates 44, the packaging belt 13 between the two heat sealing plates 44 is in a tightened state, and the packaging belt 13 is cut through the cutting knife 39, and the cutting port is located between the two seals.

[0047] The fifth stepping motor 34 is started to drive the two third driving shafts 47 to rotate. The corresponding disc knives 48 are driven to rotate through the third driving shafts 47 to cut the packaging belt 13. The cut is located outside the heat sealing area of the heat sealing wheel 27, so that the cut packaging belt 13 can still be separated. At the same time, the cut of the disc knife 48 is connected to the cut of the cutting knife 39, so that the finished medicine package falls from the packaging belt 13 onto the roller conveyor 8 and is conveyed out. The waste materials on both sides of the packaging belt 13 are wound up by the rotation of the winding reel 12. During the whole production process, the ultraviolet germicidal lamp 9 in the chassis 1 can sterilize the inside of the chassis 1 before and after the equipment runs, ensuring the aseptic state of the production environment.
