Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and more specifically, to a packaging labeling machine for producing hemodialysis dry powder. Background Technology

[0002] Hemodialysis dry powder is a key consumable for hemodialysis treatment of end-stage renal disease patients. Its production process must strictly adhere to medical device manufacturing standards, especially in the packaging stage, which requires efficient and sterile bagging and labeling operations through automated production lines. Labeling machines, as one of the core pieces of equipment in this production line, are mainly used to accurately affix labels containing product batch numbers, expiration dates, and production information to the surface of hemodialysis dry powder packaging bags, ensuring product traceability and guaranteeing label adhesion to withstand the environmental challenges of subsequent warehousing, transportation, and clinical use. Currently, hemodialysis dry powder packaging bags are mostly made of composite film materials, and the bag body is prone to shape changes after filling due to fluctuations in the internal dry powder content or external forces during transportation. This can easily lead to the following problems when labeling hemodialysis dry powder packaging bags by the labeling machine.

[0003] Before labeling, packaging bags are prone to surface wrinkles due to compression during transport or uneven distribution of dry powder inside the bag. This causes the label to deform with the wrinkles during application and can also create gaps, resulting in loose adhesion and reduced label strength. Existing flattening mechanisms, which use hydraulic cylinders to drive pressure plates, are prone to bursting due to excessive pressure squeezing air inside the bag, causing dry powder leakage and material waste. They also cannot adapt to packaging bags of different thicknesses, further limiting the applicability of the equipment. In addition, the label separation process often relies on existing mechanical peeling structures, which have poor adaptability to labels that are too wide or made of soft materials. Labels may curl or fail to separate from the backing paper, directly leading to missed labeling and affecting the continuity of the production line. Furthermore, after the label is bonded to the packaging bag, residual air from the bonding process cannot be expelled, easily forming air bubbles and reducing the adhesion effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a packaging and labeling machine for producing hemodialysis dry powder.

[0005] The technical solution is as follows: A packaging and labeling machine for producing hemodialysis dry powder includes a machine casing. Two conveying fastening seats are fixedly connected to the top of the machine casing. A vacuum conveying mechanism is fixedly connected to the top of the conveying fastening seats. A touch control panel is fixedly connected to the top of the machine casing. A machine adjustment seat is fixedly connected to the top of the machine adjustment seat. A vertical adjustment slide rod is fixedly connected to the vertical adjustment slide rod. A front and rear adjustment slide rod is slidably connected to the vertical adjustment slide rod. A label plate is slidably connected to the front and rear adjustment slide rod. A material tray mechanism is rotatably connected to the top of the label plate. A receiving tray is rotatably connected to the bottom of the label plate. A drive roller assembly is rotatably connected to the label plate. A label peeling plate is rotatably connected to the bottom of the label plate on the side away from the receiving tray. A flattening component for further flattening the packaging bag is provided at the bottom of the label peeling plate. The flattening assembly includes two supports fixedly connected to both sides of the bottom of the label peeling plate. A roller is rotatably connected between the two supports. The bottom of the label peeling plate is provided with an air blowing assembly to assist in separating the label paper from the backing paper. The label peeling plate is provided with a piercing assembly to punch holes in the label paper. The air blowing assembly includes an electric air pump fixedly connected to the bottom of the label peeling plate. Both ends of the electric air pump are fixedly connected to air pipes, and the ends of the two air pipes away from the electric air pump are fixedly connected to a nozzle. The puncture assembly includes a fixing frame 1 fixedly connected to both sides of the bottom of the label peeling plate, a puncture bar rotatably connected between the two fixing frames 1, and a rolling bar 2 rotatably connected between the two fixing frames 1.

[0006] Furthermore, the top of the conveyor fastening seat is inclined, and the vacuum conveying mechanism installed on the inclined part of the top of the conveyor fastening seat is also in an inclined state. The vacuum conveying mechanism consists of a side frame, a driver, a belt, an infrared sensor, a vacuum system, and a stop bar. The stop bar of the vacuum conveying mechanism is located on the lower side of the side frame. The up and down adjusting slide rod is kept in the same inclined state as the vacuum conveying mechanism under the control of the whole machine adjusting seat. The up and down adjusting slide rod makes the front and rear adjusting slide rods and the label plate all in an inclined state. The front and rear adjusting slide rods are equipped with a locking mechanism that can lock them in any position of the up and down adjusting slide rods. The label plate is equipped with a locking mechanism that can lock it in any position of the front and rear adjusting slide rods. The receiving tray is driven by a motor. The label strip is placed on the tray mechanism. The label strip passes through the transmission roller group and needs to go around the bottom of the label peeling plate in the middle. Finally, it is wound on the receiving tray. The label peeling plate is equipped with a locking mechanism that can lock it on the label plate at different inclination angles.

[0007] Furthermore, the bottom height of the rolling rod is lower than the bottom height of the label stripping plate.

[0008] Furthermore, the air tube is made of rigid metal pipe, and the nozzle blows air towards the end of the label peeling plate away from the label head plate.

[0009] Furthermore, the barb is located on the upper surface of the label peeling plate at the end away from the label head plate, and the bottom of the barb abuts against the upper surface of the label peeling plate. The second rolling rod is made of sponge material, and the height of the second rolling rod is the same as the height of the first rolling rod.

[0010] Furthermore, the vacuum conveying mechanism is equipped with a hot pressing component for pressing the label paper completely onto the packaging bag of hemodialysis dry powder. The hot pressing component includes two fixed frames two fixedly connected to both sides of the vacuum conveying mechanism. Each of the two fixed frames two has a sliding groove one. A sliding frame one is slidably connected inside each of the two sliding grooves one. A rotating shaft one is rotatably connected inside the two sliding frames one. A hot pressing roller is fixedly connected to the outer surface of the rotating shaft one.

[0011] Furthermore, the bottom of the hot press roller is in contact with the upper surface of the vacuum conveyor belt, and an electric heating wire is installed inside the hot press roller.

[0012] Furthermore, the vacuum conveying mechanism is equipped with a sorting component for cleaning and leveling the packaging bags of hemodialysis dry powder. The sorting component includes four fixed frames three fixedly connected to both sides of the vacuum conveying mechanism. Each fixed frame three has a slide groove two. A suction device is fixedly connected to the top of the vacuum conveying mechanism. A sliding frame two is slidably connected inside each slide groove two. Two sets of sliding frames two are arranged in pairs. A fixed plate is connected between the two sliding frames two on the same side. A rotating shaft two is rotatably connected inside the two sliding frames two in one set. A solid roller is fixedly connected to the rotating shaft two. A rotating shaft three is rotatably connected inside the two sliding frames two in the other set. A cleaning brush is fixedly connected to the rotating shaft three. Gears are fixedly connected to the same end of the rotating shaft two and the rotating shaft three. The two gears mesh with each other.

[0013] Furthermore, the suction device is externally connected to a suction pump. The suction device is located on the side of the cleaning brush away from the solid roller. A motor is installed at the end of the rotating shaft away from the gear. The bottom of the solid roller is in contact with the belt of the vacuum conveying mechanism.

[0014] Based on the above, the beneficial effects of the packaging and labeling machine for producing hemodialysis dry powder according to this utility model are as follows: The rolling and squeezing action of the roller effectively flattens the upper surface of the hemodialysis powder packaging bag, ensuring that the upper surface remains flat before labeling. This allows the label to adhere effectively to the flat surface of the hemodialysis powder packaging bag, preventing incomplete adhesion due to localized protrusions. Consequently, it ensures the label adheres firmly to the hemodialysis powder packaging bag. The high-speed airflow from the nozzle blows the label paper, which helps the label paper separate from the backing paper. This prevents the label paper from failing to separate from the backing paper, which could lead to missing labels on the packaging bags of hemodialysis dry powder. It also reduces the curling of wide labels during the separation process. The airflow can apply a uniform pushing force to the label paper, allowing the label to be pasted onto the packaging bags of hemodialysis dry powder in a flat position. The rotatable bar can punch holes in the label paper on the top surface of the label peeler. If there are air bubbles between the label paper and the packaging bag of hemodialysis dry powder, they can be discharged through the holes punched by the bar, thus preventing air bubbles from appearing after the label paper is pasted on the packaging bag of hemodialysis dry powder and improving the stability of label adhesion. The heated hot press roller can heat-press the packaging bag of hemodialysis dry powder. The hot press roller can heat the label on the packaging bag of hemodialysis dry powder. After heating, the rolling of the hot press roller can make the adhesive on the back of the label paper enter a better bonding state, forming a stronger bond, reducing the possibility of the label peeling or falling off during subsequent transportation, stacking, and tearing. The reverse rotation of the cleaning brush cleans the upper surface of the hemodialysis powder packaging bag. Combined with the suction action of the suction pump, the suction device removes the cleaned dust or foreign objects, preventing them from falling onto the next hemodialysis powder packaging bag. This ensures that the upper surface of the hemodialysis powder packaging bag remains clean before labeling, preventing dust or other foreign objects from affecting the adhesion between the label and the packaging bag, and improving the adhesion strength between the label and the packaging bag. The solid roller's own weight allows it to better adapt to the thickness of hemodialysis dry powder packaging bags. Furthermore, compared to existing methods that directly use hydraulic cylinders and pressure plates to flatten the packaging bags, the solid roller's pressure is less excessive. This prevents excessive compression of the air inside the packaging bags, thus preventing them from bursting. It ensures that the packaging bags are flattened while preventing damage.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] The embodiments provided by this utility model will be described in detail below: like Figures 1 to 4 and Figure 6As shown, a packaging and labeling machine for producing hemodialysis dry powder includes a machine casing 1. Two conveying fastening seats 11 are fixedly connected to the top of the machine casing 1. A vacuum conveying mechanism 12 is fixedly connected to the top of the conveying fastening seats 11. A touch control panel 13 is fixedly connected to the top of the machine casing 1. A machine adjustment seat 14 is fixedly connected to the top of the machine adjustment seat 14. An up-down adjustment slide rod 15 is fixedly connected to the top of the up-down adjustment slide rod 15. A front-back adjustment slide rod 16 is slidably connected to the front-back adjustment slide rod 16. A label plate 17 is rotatably connected to the top of the label plate 17. A material tray mechanism 18 is rotatably connected to the bottom of the label plate 17. A receiving tray 19 is rotatably connected to the bottom of the label plate 17. A transmission roller assembly 110 is rotatably connected to the label plate 17. A label peeling plate 111 is rotatably connected to the bottom of the label plate 17 on the side away from the receiving tray 19. A flattening component for further flattening the packaging bag is provided at the bottom of the label peeling plate 111. The flattening assembly includes two supports 21 fixedly connected to both sides of the bottom of the label peeling plate 111. A roller 22 is rotatably connected between the two supports 21. The bottom height of the roller 22 is lower than the bottom height of the label peeling plate 111, so that the roller 22 can effectively contact the packaging bag of hemodialysis dry powder. The bottom of the label peeling plate 111 is provided with an air blowing assembly to assist in the separation of the label paper from the backing paper. The label peeling plate 111 is provided with a puncture assembly for punching holes in the label paper.

[0019] It should be noted that the following is a supplementary description of existing equipment, and can be used as a reference for the operation and debugging of existing equipment. The top of the conveying fastening seat 11 is inclined, and the vacuum conveying mechanism 12 installed on the inclined part of the top of the conveying fastening seat 11 is also in an inclined state. The vacuum conveying mechanism 12 consists of a side frame, a driver, a belt, an infrared sensor, a vacuum system, and a stop bar. The stop bar of the vacuum conveying mechanism 12 is located on the lower side of the side frame to prevent the packaging bag of hemodialysis dry powder from slipping off the belt of the vacuum conveying mechanism 12 due to the inclination of the vacuum conveying mechanism 12, ensuring that the packaging bag of hemodialysis dry powder can always be driven and conveyed on the belt of the vacuum conveying mechanism 12. The vacuum conveying mechanism 12 is an existing structure, and the internal vacuum system is used to adsorb the packaging bag of hemodialysis dry powder onto the belt to prevent the packaging bag of hemodialysis dry powder from slipping off the belt during vacuum conveying. When slippage occurs on the belt of mechanism 12, the up-down adjusting slide bar 15, under the control of the whole machine adjusting seat 14, maintains the same tilt state as the vacuum conveying mechanism 12. The up-down adjusting slide bar 15 makes the front and rear adjusting slide bars 16 and the label plate 17 tilted. The front and rear adjusting slide bars 16 are equipped with a locking mechanism that can lock the front and rear adjusting slide bars 16 at any position of the up-down adjusting slide bar 15. The label plate 17 is equipped with a locking mechanism that can lock the label plate 17 at any position of the front and rear adjusting slide bars 16. The receiving tray 19 is driven by a motor. The label strip is placed on the tray mechanism 18. The label strip passes through the transmission roller group 110 and needs to pass around the bottom of the peeling plate 111 in the middle. Finally, it is wound on the receiving tray 19. The peeling plate 111 is equipped with a locking mechanism that can lock the peeling plate 111 on the label plate 17 at different tilt angles.

[0020] Specifically, the following is a brief description of the operating principle of the existing equipment structure. The specific operation can be referenced from existing labeling machines. After starting the equipment, the driver of the vacuum conveyor mechanism 12 drives the belt of the vacuum conveyor mechanism 12 for transmission. The packaging bags of hemodialysis dry powder to be labeled are placed on the belt of the vacuum conveyor mechanism 12 for conveying via the existing card mechanism or manual feeding. When the belt of the vacuum conveyor mechanism 12 carries the packaging bags of hemodialysis dry powder to below the label peeling plate 111, the infrared sensor on the vacuum conveyor mechanism 12 detects the packaging bags of hemodialysis dry powder, and the touch control panel 13 controls the material receiving. The motor of the receiving tray 19 drives the receiving tray 19 to rotate. After the receiving tray 19 rotates, it can roll up the label strip. When the label strip passes the peeling plate 111, it will bend at the end away from the label head plate 17. The back paper of the label strip will wrap around to the bottom of the peeling plate 111. The label paper of the label strip will detach from the back paper along the inclined direction of the peeling plate 111. The detached label paper will fall on the surface of the hemodialysis dry powder packaging bag. The label paper will stick to the hemodialysis dry powder packaging bag. The belt of the vacuum conveyor mechanism 12 continues to transport it to the next collection process. At this time, the labeling process of the hemodialysis dry powder packaging bag is completed.

[0021] During the process of the aforementioned hemodialysis dry powder packaging bag being conveyed to the label peeling plate 111, and when the infrared sensor on the vacuum conveying mechanism 12 does not detect the hemodialysis dry powder packaging bag, the hemodialysis dry powder packaging bag will pass under the bottom of the roller 22. During the process of the hemodialysis dry powder packaging bag passing under the bottom of the roller 22, the hemodialysis dry powder packaging bag will be subjected to the rolling and squeezing of the roller 22. Through the rolling and squeezing of the roller 22, the upper surface of the hemodialysis dry powder packaging bag is effectively squeezed flat, so that the upper surface of the hemodialysis dry powder packaging bag can remain flat before being labeled, allowing the label paper to be effectively pasted to the flat surface of the hemodialysis dry powder packaging bag. This avoids the situation of incomplete pasting caused by local protrusions, thereby avoiding the label paper not being tightly pasted to the hemodialysis dry powder packaging bag, and ensuring the firmness of the label on the hemodialysis dry powder packaging bag.

[0022] like Figures 4 to 6 As shown, the air blowing assembly includes an electric air pump 31 fixedly connected to the bottom of the label peeling plate 111. Both ends of the electric air pump 31 are fixedly connected to air pipes 32, and the ends of the two air pipes 32 away from the electric air pump 31 are fixedly connected to a nozzle 33.

[0023] It should be noted that the air tube 32 is made of rigid metal pipe, and the nozzle 33 is rectangular. The air outlet of the nozzle 33 is directed towards the end of the label peeling plate 111 away from the label head plate 17. According to the above, the air outlet of the nozzle 33 is aimed at the position where the label paper and the backing paper are separated.

[0024] Specifically, during the separation process of the label paper and the backing paper, the backing paper will wrap around from the end of the peeling plate 111 away from the label head plate 17 to the bottom of the peeling plate 111, and the label paper will move forward along the inclined direction of the peeling plate 111. However, if part of the label paper and the backing paper are not effectively separated during this process, that is, if the label paper and the backing paper remain stuck together, the label paper will wrap around to the bottom of the peeling plate 111 along with the backing paper. At this time, the packaging bag of hemodialysis dry powder cannot be labeled. During this process, that is, during the separation of the label paper and the backing paper, when the infrared sensor of the vacuum conveying mechanism 12 detects the passing of the packaging bag of hemodialysis dry powder, the touch control panel 13 will also control the electric air pump 31 to start briefly. After the electric air pump 31 starts briefly, it will quickly pump gas into the nozzle 33 through the air pipe 32. The gas will be quickly blown out from the air outlet of the nozzle 33. Since the air outlet of the nozzle 33 is aligned with the position where the label paper and the backing paper are separated, refer to Figure 6 As shown, the airflow is directed towards the lower right side of the label peeling plate 111. The high-speed airflow from the nozzle 33 blows the label paper, which helps the label paper separate from the backing paper. This prevents the label paper from failing to separate from the backing paper, which could lead to missing labels on the packaging bags of hemodialysis dry powder. It also reduces the curling of wide labels during the separation process. The airflow can apply a uniform pushing force to the label paper, allowing the label to be pasted onto the packaging bags of hemodialysis dry powder in a flat position.

[0025] It should be noted that the aforementioned rapid airflow is only a brief burst of air and will not be continuous.

[0026] like Figures 4 to 6 As shown, the puncture assembly includes a fixing frame 41 fixedly connected to both sides of the bottom of the label peeling plate 111, a piercing rod 42 rotatably connected between the two fixing frames 41, and a rolling rod 43 rotatably connected between the two fixing frames 41.

[0027] It should be noted that the barb 42 is located on the upper surface of the label peeling plate 111 away from the label head plate 17, and the bottom of the barb 42 is in contact with the upper surface of the label peeling plate 111. The second rolling rod 43 is made of sponge material, and the height of the second rolling rod 43 is the same as the height of the first rolling rod 22.

[0028] Specifically, when the label strip is wrapped from the end of the peeling plate 111 away from the label head plate 17 to the bottom of the peeling plate 111, the label strip needs to be passed between the barb 42 and the upper surface of the peeling plate 111. As the receiving tray 19 rolls up, the label strip moves on the peeling plate 111. The movement of the label strip will cause the barb 42 to rotate between the two fixed frames 41. The rotatable barb 42 can punch holes in the label paper that has passed through the upper surface of the peeling plate 111. If there are air bubbles between the label paper and the packaging bag of hemodialysis dry powder, they can be discharged through the holes punched by the barb 42. After the label is peeled off from the peeling plate 111, it may contain air before it comes into contact with the bag surface. The holes allow this air to escape directly when it is attached, avoiding the air being "pressed" between the label and the bag surface to form air bubbles. This avoids the label paper being delayed or shifted due to air obstruction, and indirectly improves the labeling speed of the automated hemodialysis dry powder production line.

[0029] It should be noted that the specific structure of the label stripping plate 111 is as follows: Figure 4 As shown, the label peeling plate 111 comprises two layers. The label strip enters from the upper surface of the upper label peeling plate 111 to the label peeling position, and then returns to the receiving tray 19 from the bottom of the lower label peeling plate 111. The barb 42 is positioned near the ends of the upper and lower label peeling plates 111, meaning the label strip needs to pass over the barb 42 to move from the upper to the lower label peeling plate 111. Based on the position of the barb 42 and the label peeling method, the label peeling and perforation are completed. It should be noted that the perforations of the aforementioned barb 42 on the label paper are small in size and few in number, and will not affect the display of text, numbers, and graphics on the label paper. In addition, after the packaging bag of hemodialysis dry powder is labeled, the conveyor belt of the vacuum conveyor mechanism 12 will continue to move the packaging bag of hemodialysis dry powder. When the packaging bag of hemodialysis dry powder passes the second roller 43, the second roller 43 will also squeeze the packaging bag of hemodialysis dry powder. Since the label has already come into contact with the packaging bag of hemodialysis dry powder, when the packaging bag of hemodialysis dry powder passes the second roller 43, the squeezing of the second roller 43 can initially press the label paper onto the packaging bag of hemodialysis dry powder.

[0030] like Figures 1 to 3 and Figure 7 As shown, the vacuum conveying mechanism 12 is equipped with a hot pressing assembly for pressing the label paper completely onto the packaging bag of hemodialysis dry powder. The hot pressing assembly includes two fixed frames 51 fixedly connected to both sides of the vacuum conveying mechanism 12. Each of the two fixed frames 51 has a sliding groove 52. The sliding frame 54 is slidably connected inside the two sliding grooves 52. The two sliding frames 54 are rotatably connected to a rotating shaft 55 on their adjacent sides. A hot pressing roller 56 is fixedly connected to the outer surface of the rotating shaft 55.

[0031] It should be noted that the bottom of the hot press roller 56 is in contact with the upper surface of the belt of the vacuum conveying mechanism 12. The hot press roller 56 is made of aluminum alloy and its surface is coated with Teflon to improve thermal conductivity and prevent sticking. The hot press roller 56 is equipped with an electric heating wire with a temperature set between 60 and 80°C. This wire can only soften the adhesive on the label paper and will not cause heat deformation to the packaging bag of hemodialysis dry powder. When the electric heating wire is energized, it can raise the surface temperature of the hot press roller 56.

[0032] Specifically, after the labeled hemodialysis powder packaging bags pass through the roller 43, during the continued conveying process of the vacuum conveyor 12 belt, the belt of the vacuum conveyor 12 will drive the hemodialysis powder packaging bags through the hot pressure roller 56. Because the vacuum system inside the vacuum conveyor 12 will adsorb the hemodialysis powder packaging bags onto the belt, the hemodialysis powder packaging bags will push up the hot pressure roller 56 as the vacuum conveyor 12 belt moves, causing the hot pressure roller 56 to move upward through the rotating shaft 55 and the two sliding frames 54 respectively inside the two sliding grooves 52. The hot press roller 56, under its own weight and rotation, can squeeze the packaging bag of hemodialysis dry powder. After the heating wire inside the hot press roller 56 is energized, the surface of the hot press roller 56 has a certain temperature. The heated hot press roller 56 can heat the packaging bag of hemodialysis dry powder. The hot press roller 56 can heat the label on the packaging bag of hemodialysis dry powder. After heating, the rolling of the hot press roller 56 can make the adhesive on the back of the label paper enter a better bonding state, forming a stronger bond, reducing the possibility of the label peeling or falling off during subsequent transportation, stacking, and tearing.

[0033] like Figures 1 to 3 and Figure 8 As shown, the vacuum conveying mechanism 12 is equipped with a sorting component for cleaning and leveling the packaging bags of hemodialysis dry powder. The sorting component includes four fixed frames 61 fixedly connected to both sides of the vacuum conveying mechanism 12. Each fixed frame 61 has a groove 62. A suction device 63 is fixedly connected to the top of the vacuum conveying mechanism 12. A sliding frame 64 is slidably connected inside each groove 62. Two sets of sliding frames 64 are arranged in pairs. A fixed plate is connected between the two sliding frames 64 on the same side. A rotating shaft 65 is rotatably connected inside the two sliding frames 64 in one set. A solid roller 66 is fixedly connected to the rotating shaft 65. A rotating shaft 67 is rotatably connected inside the two sliding frames 64 in the other set. A cleaning brush 68 is fixedly connected to the rotating shaft 67. Gears 69 are fixedly connected to the same end of the rotating shaft 65 and the rotating shaft 67. The two gears 69 mesh with each other.

[0034] It should be noted that the suction device 63 is externally connected to a suction pump, and the exhaust port of the suction pump can be connected to a dust collection bag. The suction device 63 is located on the side of the cleaning brush 68 away from the solid roller 66. A motor is provided at the end of the rotating shaft 65 away from the gear 69. The motor can drive the rotating shaft 65 to make the solid roller 66 rotate synchronously in the conveying direction of the belt of the vacuum conveying mechanism 12. The bottom of the solid roller 66 is in contact with the belt of the vacuum conveying mechanism 12.

[0035] Specifically, while the vacuum conveying mechanism 12 is conveying, the motor of the second rotating shaft 65 also drives the second rotating shaft 65 to rotate within the second sliding frame 64. The second rotating shaft 65 drives the solid roller 66 to rotate synchronously. The rotation direction of the solid roller 66 is along the conveying direction of the belt of the vacuum conveying mechanism 12. The rotation of the second rotating shaft 65 drives the gear 69 on it to rotate. Through the meshing transmission of the two gears 69, the third rotating shaft 67 also causes the third rotating shaft 67 to rotate in the opposite direction inside the second sliding frame 64. The third rotating shaft 67 drives the cleaning brush 68 to rotate in the opposite direction, that is, the rotation direction of the cleaning brush 68 is against the conveying direction of the belt of the vacuum conveying mechanism 12. When the unlabeled packaging bag of hemodialysis dry powder is placed in the vacuum conveying mechanism 12... 2. During the conveying process, when the belt of the vacuum conveying mechanism 12 drives the packaging bag of hemodialysis dry powder past the cleaning brush 68, the reverse rotation of the cleaning brush 68 can clean the upper surface of the packaging bag of hemodialysis dry powder. The suction action of the suction pump causes the suction device 63 to suck up the cleaned dust or foreign objects, preventing dust or foreign objects from falling onto the next packaging bag of hemodialysis dry powder. This prevents dust or other foreign objects from adhering to the upper surface of the packaging bag of hemodialysis dry powder, ensuring that the upper surface of the packaging bag of hemodialysis dry powder remains clean before labeling. This also prevents dust or other foreign objects from affecting the adhesion of the subsequent label paper to the packaging bag of hemodialysis dry powder, thereby improving the adhesion strength between the label paper and the packaging bag of hemodialysis dry powder.

[0036] Furthermore, as the belt of the vacuum conveyor mechanism 12 continues to move the packaging bag of hemodialysis dry powder, the packaging bag will pass through the solid roller 66. Since the rotation direction of the solid roller 66 is along the conveying direction of the belt of the vacuum conveyor mechanism 12, the rotation of the solid roller 66 will not affect the conveying of the packaging bag of hemodialysis dry powder. When the packaging bag of hemodialysis dry powder passes through the solid roller 66, it will lift the solid roller 66. The solid roller 66 will drive the sliding frame 64 to move inside the slide groove 62 through the rotating shaft 65. During the upward movement, because the solid roller 66 is solid, its own weight allows it to better adapt to the thickness of the hemodialysis dry powder packaging bag. At the same time, compared to the existing method of directly pressing the hemodialysis dry powder packaging bag with a hydraulic cylinder and pressure plate, the pressure of the solid roller 66 is not excessive. This prevents the air inside the hemodialysis dry powder packaging bag from being excessively compressed, thus preventing the packaging bag from bursting. It ensures that the packaging bag of hemodialysis dry powder is flattened while preventing damage.

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.
