A packaging equipment for finished powdered medicated patches

Abstract

This utility model discloses a powder patch packaging device, including a support base, a conveyor frame, and a conveyor belt. A transmission belt is mounted on the conveyor frame, and the transmission belt has the same conveying speed as the main conveyor belt. Several first vacuum pumps are installed on the outside of the transmission belt. Each of the first vacuum pumps has a shield at one end, and a drainage hood is installed on the outside of the shield. A guide hose is installed between the drainage hood and the first vacuum pump, and a discharge pipe is installed at the other end of the drainage hood, penetrating the inside of the transmission belt. The shields position and isolate the patch from the packaging edge. Combined with the negative pressure generated by the first vacuum pumps, the drainage hood directionally removes residual powder from the packaging surface, ensuring that there is no powder residue on the packaging surface before heat sealing. This allows the aluminum foil and plastic box to adhere tightly, completely eliminating sealing gaps and effectively preventing external moisture intrusion and powder from absorbing moisture and clumping.

Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a packaging equipment for finished powdered medicine patches. Background Technology

[0002] In the industrial production of patches (such as acupoint patches, Sanfu patches, and pain relief patches), finished product packaging is a crucial step in ensuring stable quality and extending shelf life. For "powdered patches" or "powder-based patches," which contain volatile and moisture-absorbing powdered medications, the requirements for airtight packaging are particularly stringent. These patches typically have the powdered medication placed on a thin substrate sheet, which is then bonded to the substrate edges to form a single unit. This is followed by placing the film in a plastic box, and finally, a packaging machine heat-presses aluminum foil onto the plastic box to complete the final packaging.

[0003] However, the existing production process has significant technical defects: powdered drugs are prone to leakage during the transfer to the plastic box, with some powder adhering to the sealing surface of the plastic box's edge. When the aluminum foil and plastic box are heat-sealed, this leaked powder becomes trapped between them, preventing a tight seal and creating gaps. These gaps compromise the packaging's barrier properties, allowing external moisture to penetrate the box, causing the powder to absorb moisture and clump. Simultaneously, volatile active ingredients in the drug evaporate and are lost through these gaps, severely impacting the efficacy and shelf life of the medicated patch. Furthermore, inadequate sealing can lead to secondary contamination during transportation and storage, failing to meet the quality control requirements for the industrial production of powdered medicated patches.

[0004] Therefore, this utility model provides a packaging device for finished powdered medicated patches. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a packaging equipment for finished powdered medicine patches to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder patch packaging device, comprising a support base, a conveyor frame, and a conveyor belt. A transmission belt is mounted on the conveyor frame, and the transmission belt has the same conveying speed as the conveyor belt. Several first vacuum pumps are mounted on the outer side of the transmission belt. Each of the first vacuum pumps has a shield at one end, and a drainage hood is mounted on the outer side of the shield. A guide hose is installed between the drainage hood and the first vacuum pump. A discharge pipe is mounted at the other end of the drainage hood, and the discharge pipe penetrates the inner side of the transmission belt, communicating with the internal space of the transmission belt.

[0007] Preferably, two drive rods are provided on the inner side of the transmission belt, and two drive cylinders are installed on the side walls of the two drive rods. The discharge pipe passes between the two drive cylinders, and side baffles are provided on both sides of the transmission belt. The two drive rods are rotatably connected between the two side baffles.

[0008] Preferably, each of the two side baffles has two side legs installed on one side, and all four side legs are installed on the top of the conveyor frame. One of the side legs has a drive mechanism installed on one side, and the drive mechanism is connected to one of the drive rods.

[0009] Preferably, one of the side baffles has a side opening on its side wall, and a second air extractor is installed on the outside of the side baffle, with the air inlet of the second air extractor corresponding to the position of the side baffle.

[0010] Preferably, an L-shaped guide pipe is installed on one side of the second air pump, and a storage tank is detachably connected to one end of the L-shaped guide pipe. An exhaust ring cover is provided on the outside of the storage tank.

[0011] Preferably, one end of each of the first air pumps is equipped with an electric telescopic rod, and the output end of the electric telescopic rod is installed at one end of the corresponding shield.

[0012] Compared with the prior art, the present invention has the following advantages: By positioning and isolating the patch from the packaging edge using a shield, and combining the negative pressure generated by the first vacuum pump, residual powder on the packaging interface is directionally removed through the drainage hood. This ensures that there is no powder residue on the packaging surface before heat sealing, allowing the aluminum foil and plastic box to fit tightly together, completely eliminating sealing gaps. This effectively prevents external moisture from entering, prevents the powder from absorbing moisture and clumping, and avoids the evaporation of volatile drug components through gaps. It also reduces the risk of secondary contamination during transportation and storage, meeting the sealing requirements of powdered patches. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Please see Figure 1-4 A powder patch packaging device includes a support base 1, a conveyor frame 11, and a conveyor belt 12. A transmission belt 2 is installed on the conveyor frame 11. The transmission belt 2 and the conveyor belt 12 have the same conveying speed. Several first vacuum pumps 3 are installed on the outside of the transmission belt 2. Each of the first vacuum pumps 3 has a shield 31 at one end. A drainage hood 32 is installed on the outside of the shield hood 31. A guide hose 321 is installed between the drainage hood 32 and the first vacuum pump 3. A discharge pipe 33 is installed at the other end of the drainage hood 32. The discharge pipe 33 passes through the inside of the transmission belt 2 and communicates with the internal space of the transmission belt 2.

[0017] It should be noted that, in this embodiment, the shield 31 is inserted into the plastic box to cover the patch inside, the shield 31 corresponds to the sealing surface of the plastic box, and the shield 31 moves together with the plastic box and then separates.

[0018] Specifically, during operation, the support base 1 provides stable support, and the conveyor belt 12 on the conveyor frame 11 continuously transports the plastic box containing the powdered patch. The transmission belt 2 and the conveyor belt 12 maintain the same conveying speed to achieve synchronous operation and ensure coordinated action. Several first suction machines 3, which move synchronously with the outer side of the transmission belt 2, start operation when the plastic box is transported to the corresponding workstation: the shield 31 is precisely inserted into the plastic box, covering the entire patch, and its position precisely corresponds to the sealing surface of the edge of the plastic box. This avoids touching the patch and causing secondary powder spillage, and focuses on the sealing edge area that needs to be cleaned. At this time, the first suction machine 3 generates negative pressure, and the suction is transmitted to the drainage hood 32 through the guide hose 321. The drainage hood 32 is close to the sealing edge of the plastic box and efficiently sucks up the powder that was missed and attached to the area during the transfer. The sucked-up powder is then discharged through the discharge pipe 33. The powder is collected and processed in the inner space of the conveyor belt 2. The design of the discharge pipe 33, which runs through the inner side of the conveyor belt 2, ensures that the powder cleaning path is closed and avoids secondary pollution. As the plastic box continues to move with the conveyor belt 12, the shield 31 moves synchronously with the plastic box for a certain distance to fully clean it. Then, they are smoothly separated, and the plastic box enters the subsequent heat-sealing process. The shield 31 positions and isolates the patch from the sealing edge. Combined with the negative pressure generated by the first vacuum pump 3, the residual powder on the sealing surface is directionally removed through the drainage hood 32. This ensures that there is no powder residue on the sealing surface before heat-sealing, allowing the aluminum foil and the plastic box to fit tightly together, completely eliminating sealing gaps. This effectively prevents external moisture from entering, prevents the powder from absorbing moisture and clumping, and avoids the evaporation of volatile drug components through gaps. It also reduces the risk of secondary pollution during transportation and storage, meeting the sealing requirements of powder-type patches.

[0019] In one embodiment of this utility model, such as Figures 1-4 As shown, two drive rods 21 are provided on the inner side of the transmission belt 2, and two drive cylinders 22 are installed on the side walls of the two drive rods 21. The discharge pipe 33 passes between the two drive cylinders 22. Side baffles 23 are provided on both sides of the transmission belt 2. The two drive rods 21 are rotatably connected between the two openings 232.

[0020] It should be noted that the gap between the two drive cylinders 22 described in this embodiment makes way for the passing discharge pipe 33.

[0021] Specifically, two drive rods 21 on the inner side of the transmission belt 2 are rotatably connected between the side baffles 23 on both sides. The drive rods 21 provide support and drive for the operation of the transmission belt 2 through two drive cylinders 22. The two drive cylinders 22 installed on the side wall of the drive rods 21 form a specific gap. When the discharge pipe 33 moves with the transmission belt 2, it will pass through the gap between the two drive cylinders 22. This gap provides precise clearance space for the discharge pipe 33, avoiding collision or friction between the discharge pipe 33 and the drive rods 21 and drive cylinders 22.

[0022] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the two side baffles 23 has two side legs 231 installed on one side, and all four side legs 231 are installed on the top of the conveyor frame 11. One of the side legs 231 has a drive mechanism 24 installed on one side, and the drive mechanism 24 is connected to one of the drive rods 21.

[0023] It should be noted that the drive mechanism 24 described in this embodiment is a drive motor.

[0024] Specifically, two side legs 231 installed on each side of the two side baffles 23 jointly and stably support and fix the side baffles 23 to the top of the conveyor frame 11, providing a stable installation foundation for the side baffles 23 and subsequent connecting components, ensuring that the overall structure does not shift during equipment operation. At the same time, the drive mechanism 24 installed on one side of one of the side legs 231 forms a transmission connection with one of the drive rods 21. When the drive motor 24 starts, it outputs power and drives the drive rod 21 connected to it to rotate. Since both drive rods 21 are rotatably connected between the two side baffles 23, and the transmission belt 2 is wrapped around the outside of the drive rod 21, the rotation of the drive rod 21 will drive the transmission belt 2 to achieve cyclic operation, thereby causing the first vacuum pump 3, shield 31 and other powder cleaning components on the outside of the transmission belt 2 to move synchronously with the transmission belt 2, ensuring that they can accurately cooperate with the plastic box on the conveyor belt 12, continuously completing the removal of residual powder on the packaging surface, and providing power and structural support for the sealing of subsequent hot-pressing packaging.

[0025] In one embodiment of this utility model, such as Figures 1-4 As shown, one of the side baffles 23 has a side opening 232 on its side wall, and a second air extractor 4 is installed on the outside of the side baffle 23. The air inlet of the second air extractor 4 corresponds to the position of the side baffle 23.

[0026] It should be noted that the second vacuum pump 4 described in this embodiment extracts any missed powder from the space between the transmission belt 2 and the two side baffles 23 through the side opening 232.

[0027] Specifically, a side opening 232 on the side wall of one of the side baffles 23 allows the enclosed space formed between the transmission belt 2 and the two side baffles 23 to communicate with the outside, providing a channel for powder extraction. A second vacuum pump 4, installed outside the side baffle 23, has its air inlet precisely aligned with the side baffle 23, ensuring that the air inlet can communicate with the space between the transmission belt 2 and the side baffle 23 through the side opening 232. When the equipment is running, after the first vacuum pump 3 sucks in residual powder from the plastic box sealing surface and discharges it through the discharge pipe 33 into the inner space of the transmission belt 2, some powder may scatter into the gap between the transmission belt 2 and the two side baffles 23 during the transmission belt 2's cyclical movement. At this time, the second vacuum pump 4 starts, generating negative pressure suction in this gap space through the side opening 232 to promptly extract and collect the scattered powder, preventing powder from accumulating inside the equipment and causing contamination, or from re-adhering to the plastic box sealing surface with the transmission belt, affecting the sealing effect. This further improves the thoroughness of powder cleaning and ensures sealing quality.

[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, an L-shaped guide pipe 41 is installed on one side of the second vacuum pump 4. One end of the L-shaped guide pipe 41 is detachably connected to a storage tank 42. An exhaust ring cover 421 is provided on the outside of the storage tank 42.

[0029] It should be noted that the storage tank 42 described in this embodiment is used to collect powder.

[0030] Specifically, after the second vacuum pump 4 is started, it extracts any loose powder that has fallen between the transmission belt 2 and the two side baffles 23 through the side opening 232 of the side baffle 23. The extracted powder is carried by the airflow into the L-shaped guide pipe 41 installed on one side of the second vacuum pump 4. The L-shaped guide pipe 41 uses its own structure to directionally transport the powder airflow to the storage tank 42, which is detachably connected to its other end. The storage tank 42 collects the powder centrally, preventing the powder from being discharged randomly and causing internal pollution of the equipment or environmental dust problems. At the same time, an exhaust ring cover is installed on the outside of the storage tank 42. 421 can exhaust and guide the airflow carrying the powder during the extraction process while the powder is stored in the storage tank 42, ensuring smooth airflow and preventing the powder from escaping from the opening of the storage tank 42. In addition, the detachable connection design between the storage tank 42 and the L-shaped guide pipe 41 facilitates the subsequent cleaning or treatment of the collected powder, ensuring the continuity of powder collection and improving the convenience of equipment maintenance. Furthermore, it can work in conjunction with the second vacuum pump 4 to achieve efficient treatment of any leaked powder, consolidate the cleaning effect of the sealing surface, and ensure the sealing quality of the medicated patch.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, several first vacuum pumps 3 are equipped with electric telescopic rods 34 at one end, and the output end of the electric telescopic rods 34 is installed at one end of the corresponding shield 31.

[0032] Specifically, several electric telescopic rods 34 are installed at one end of the first vacuum pumps 3, and their output ends are fixedly connected to one end of the corresponding shield 31. The height of the shield 31 and the drainage hood 32 linked to the shield 31 can be adjusted by their own telescopic movement. When the conveyor belt 12 transports the plastic box containing the patch to the powder cleaning station, and the transmission belt 2 drives the first vacuum pump 3 to move to the corresponding position, the electric telescopic rod 34 starts and extends, pushing the shield 31 to move downward, so that the shield 31 is accurately inserted into the plastic box and covers the patch. At the same time, the drainage hood 32 is brought close to the sealing edge of the plastic box, providing a suitable position for the first vacuum pump 3 to extract the residual powder under negative pressure. After the powder is cleaned, the electric telescopic rod 34 retracts, pulling the shield 31 and the drainage hood 32 upward, realizing the smooth separation of the shield 31 from the plastic box, without affecting the plastic box entering the subsequent heat-sealing process with the conveyor belt 12.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: When this powder patch packaging equipment is working, the support base 1 provides stable support. The conveyor belt 12 on the conveyor frame 11 carries the plastic box containing the powder patch. The side leg 231 fixes the side baffle 23 to the top of the conveyor frame 11. The drive rod 21, which is rotatably connected between the side baffles 23, rotates under the drive motor on one side of the side leg 231, so that the transmission belt 2 wrapped around the drive cylinder 22 of the drive rod 21 runs synchronously with the conveyor belt 12. The first vacuum pump 3 on the outside of the transmission belt 2 moves with it. The electric telescopic rod 34 extends and retracts to adjust the height of the shield 31, so that it... The plastic box is inserted to cover the patch, and the drainage cover 32 is close to the edge of the packaging. The negative pressure generated by the first vacuum pump 3 is conducted to the drainage cover 32 through the guide hose 321, sucking up the residual powder on the packaging surface. Then, it passes through the discharge pipe 33 through the gap of the drive cylinder 22 and is discharged to the inside of the transmission belt 2. The side opening 232 of the side baffle 23 cooperates with the second vacuum pump 4 to extract the powder scattered between the transmission belt 2 and the side baffle 23. The powder enters the storage tank 42 for collection through the L-shaped guide pipe 41. The exhaust ring cover 421 prevents the powder from escaping. Finally, the plastic box and the shield 31 are separated and heat-sealed to ensure the sealing performance.
