Description

Technical Field

[0001] This invention relates to the field of product counting and packing technology, specifically to a counting and packing device for dialysis dry powder cylinders. Background Technology

[0002] Dialysis dry powder cartridges are key medical devices used in hemodialysis treatment for the online preparation of bicarbonate dialysate solution. The cartridges work by dissolving sodium bicarbonate powder to create a saturated solution, which is then diluted proportionally by the hemodialysis machine and mixed with solution A (acidic concentrate) to ultimately prepare a bicarbonate dialysate solution that meets treatment requirements. As a critical consumable in hemodialysis treatment, the packaging process of dialysis dry powder cartridges must strictly adhere to regulations to ensure product quality, transportation safety, and reliability in clinical use. Improper stacking or handling may damage the packaging, causing the dialysis dry powder to become damp. Because dialysis powder cartridges are narrower at the top and wider at the bottom, special care must be taken to accurately position them during packing to avoid damage to the outer packaging due to collisions or squeezing, which could lead to moisture absorption and deterioration of the powder inside. In addition, the bottom of the dialysis powder cartridge has a filter port, and collisions during packing may cause leakage of the dialysis powder. However, existing packing methods for dialysis powder cartridges, considering their special shape and function, usually involve packaging individual cartridges first and then packing them together, which consumes a lot of materials. Therefore, we propose a counting and packing device for dialysis powder cartridges. Summary of the Invention

[0003] The purpose of this invention is to provide a counting and packing device for dialysis dry powder cartridges, in order to solve the problem of existing dialysis dry powder cartridge packing methods mentioned in the background art. Considering the special shape and function of dialysis dry powder cartridges, it is usually necessary to package individual dialysis dry powder cartridges first and then pack them into boxes, which consumes a lot of materials.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a counting and packing device for dialysis dry powder cartridges, comprising: a first counting conveyor belt; Also includes: The second counting conveyor belt is located on the side of the first counting conveyor belt and is used to count and transport the boxes. A fixed seat is provided between the first counting conveyor belt and the second counting conveyor belt; The lifting frame is set inside the fixed base. A vertical moving module is fixedly connected to the top of the lifting frame. First limit rods are fixedly connected to the four corners of the lifting frame. The four first limit rods pass through the fixed base and are slidably connected to the fixed base. The feeding assembly is located inside the lifting frame. The feeding assembly includes a first feeding frame and a second feeding frame. Support frames are fixedly connected to both the left and right ends of the first and second feeding frames. A transmission belt is fixedly connected to one end of the support frame of the first and second feeding frames. Transmission wheels are driven to both ends of the transmission belt. The transmission wheels are rotatably connected to one side wall of the lifting frame. A stepper motor is fixedly connected to the outer wall of the lifting frame. The output shaft of the stepper motor is fixedly connected to one of the transmission wheels.

[0005] The first counting conveyor belt has a row of fixed rings fixedly connected to its outer surface. Each fixed ring is equidistantly distributed on the outer wall of the first counting conveyor belt. The inner wall of the fixed ring is arc-shaped, and the inner dimension of the fixed ring closer to the fixed seat is smaller than the inner dimension of the other row of fixed rings.

[0006] The second counting conveyor belt has a row of fixed rods fixedly connected to both sides, and a pressure box rod is fixedly connected to the top of the row of fixed rods. The end of the pressure box rod away from the fixed seat is set to be an upward curved arc. The first laser sensor is fixedly installed at the end of the first and second counting conveyor belts that is close to the fixed seat.

[0007] The first feeding frame has limit holes at each of its four corners, and a second limit rod passes through each of the four limit holes. A lifting plate is fixedly connected between the four second limit rods. A feeding plate is provided at the bottom of the lifting plate. The top outer wall of the feeding plate is in contact with the bottom outer wall of the lifting plate. A transmission rod is fixedly connected at the top center of the feeding plate. The top of the transmission rod passes through the first feeding frame. A limit ring is fixedly connected to the end of the transmission rod near the lifting plate. The limit ring is rotatably connected to the lifting plate.

[0008] The other side wall of the lifting frame is provided with a lifting transmission groove. The lifting transmission groove is shaped as an isosceles trapezoid. A sliding wheel is slidably connected to the inner wall of the lifting transmission groove, and one side of the sliding wheel is fixedly connected to the lifting plate.

[0009] The transmission rod is fixedly connected to a transmission tooth plate at its top, and a fitting plate is fixedly connected to the top of the transmission tooth plate. A transverse sliding groove adapted to the fitting plate is opened on the inner surface of the top of the lifting frame. Four levers are fixedly connected at equal intervals on one side of the transverse sliding groove. The levers mesh with the transmission tooth plate. Four limiting plates are fixedly connected to the outer wall of the end of the transmission rod near the transmission tooth plate. The four limiting plates are arranged in a ring array about the outer wall of the transmission rod. The limiting plates pass through the first feeding frame.

[0010] The first and second feeding racks are slidably connected to sliding rails at their other ends, and both sliding rails are fixedly connected to the lifting frame.

[0011] The bottom outer walls of both the feeding plate and the second feeding frame are equipped with two rows of vacuum suction cups. The two rows of vacuum suction cups are symmetrically arranged about the central axis of the feeding plate and the second feeding frame. There are five vacuum suction cups in each row at the bottom of the feeding plate and six vacuum suction cups in each row at the bottom of the second feeding frame. The vacuum suction cups closer to the first counting conveyor belt are higher than the vacuum suction cups closer to the second counting conveyor belt.

[0012] Each vacuum suction cup has a movable tube fixedly connected to its top, which extends into the inside of the feeding plate. A return spring is fitted on the outer wall of the movable tube.

[0013] The top outer walls of the two rows of movable tubes at the bottom of the feeding plate are all nested with fixed tubes. Each fixed tube is connected to a push plate. The feeding plate has multiple push slots that are adapted to the size of the push plate. The distance between each push slot is half the distance between two vacuum suction cups. The push plate and the feeding plate are slidably connected. Positioning slots are provided on both sides of the feeding plate. The walls of the positioning slots are arc-shaped and smooth. Roller sets are provided inside the positioning slots. The outer surface of the roller sets is in contact with the outer surface of the push plate. A slide rod is fixedly connected to the top of the roller sets. The end of the slide rod extends into the interior of the lifting plate. A telescopic spring is fixedly connected between the end of the slide rod and the lifting plate.

[0014] The present invention has at least the following beneficial effects: The alternating feeding of the first feeding rack and the second counting feeding rack can quickly lay two layers of dry powder cylinders, realizing double-layer stacking of materials in a single packing operation, effectively improving the utilization rate of packing space and packing efficiency. The opening direction of the dry powder cylinder conveyed by the first feeding rack is opposite to the opening direction of the dry powder cylinder in the first feeding rack, forming a stable interlocking structure between layers. This avoids the problem of dry powder cylinders easily tipping over and shaking in traditional double-layer stacking, and improves the overall stability of the material stack after packing.

[0015] Before the first feeding rack is filled with boxes, the pusher plate pushes the two rows of vacuum suction cups a certain distance, so that the upper and lower layers of dry powder cylinders in the box can be accurately staggered and stacked, avoiding interlayer interference, ensuring the stability and neatness of the box filling, and ensuring the arrangement accuracy of the dry powder cylinders in the box.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The embodiments provided by the present invention will be described in detail below: like Figures 1 to 12 As shown, a dialysis dry powder cartridge counting and packing device includes a first counting conveyor belt 1; Also includes: The second counting conveyor belt 2 is disposed on the side of the first counting conveyor belt 1, and the second counting conveyor belt 2 is used to count and transport the box. Fixed seat 3 is set between the first counting conveyor belt 1 and the second counting conveyor belt 2. The first counting conveyor belt 1 and the second counting conveyor belt 2 are both existing structures. The first counting conveyor belt 1 includes a motor and a rubber conveyor belt. The second counting conveyor belt 2 includes a motor and a reducer to drive the rollers. The rollers drive the goods to move. The first counting conveyor belt 1 transports dry powder cylinders that need to be packed and have been arranged. The second counting conveyor belt 2 transports neatly arranged packaging boxes. Lifting frame 4, such as Figure 2 and Figure 4 As shown, the lifting frame 4 is set inside the fixed base 3. A vertical moving module 420 is fixedly connected to the top of the lifting frame 4. Four first limiting rods 410 are symmetrically arranged on the lifting frame 4. All four first limiting rods 410 pass through the fixed base 3 and are slidably connected to the fixed base 3. Feeding components, such as Figure 4 , Figure 5 and Figure 6 As shown, the feeding assembly is located inside the lifting frame 4. The feeding assembly includes a first feeding frame 501 and a second feeding frame 502. Support frames 503 are fixedly connected to both the left and right ends of the first feeding frame 501 and the second feeding frame 502. A transmission belt 504 is fixedly connected to the support frame 503 at one end of the first feeding frame 501 and the second feeding frame 502. Transmission wheels 505 are driven to both ends of the transmission belt 504. The transmission wheels 505 are rotatably connected to one side wall of the lifting frame 4. A stepper motor 506 is fixedly connected to the outer wall of the lifting frame 4. The output shaft of the stepper motor 506 is fixedly connected to one of the transmission wheels 505.

[0020] like Figure 3 As shown, a row of fixing rings 110 is fixedly connected to the outer surface of the first counting conveyor belt 1. Each fixing ring 110 is equidistantly distributed on the outer wall of the first counting conveyor belt 1. The inner wall shape of the fixing ring 110 is set to arc shape. The inner arc dimension of the fixing ring 110 near the fixing seat 3 is smaller than the inner arc dimension of the other row of fixing rings 110, in order to adapt to the size of the dry powder cylinder with one end round and the other end conical.

[0021] like Figure 1As shown, a row of fixing rods 210 are fixedly connected to both sides of the frame of the second counting conveyor belt 2. A pressure box rod 220 is fixedly connected to the top of each row of fixing rods 210. The end of the pressure box rod 220 away from the fixing seat 3 is designed with an upward-curving arc. A first laser sensor 230 is fixedly installed at the end of both the first counting conveyor belt 1 and the second counting conveyor belt 2 near the fixing seat 3. The first laser sensor 230 is used for accurate measurement and detection on the first counting conveyor belt 1 and the second counting conveyor belt 2. The laser sensor in this embodiment is a sensor that uses laser technology for measurement, which is existing technology and will not be described in detail here.

[0022] Specifically, when the packaging box is transported to the fixed seat 3 by the second counting conveyor belt 2, the first laser sensor 230 senses the position of the packaging box and sends a feedback signal. With the cooperation of the controller of the packing system, the second counting conveyor belt 2 stops running at this time. At the same time, the first counting conveyor belt 1 starts to transport the arranged flat dry powder cylinders forward. The first laser sensor 230 located on the first counting conveyor belt 1 senses the position of the dry powder cylinders and records the number of cylinders that have passed. When the number of dry powder cylinders that have passed reaches the preset packing quantity, the first counting conveyor belt 1 stops transporting.

[0023] It should be noted that the above is a brief description of the existing transportation process before and after packaging dialysis dry powder cartridges.

[0024] It should be noted that the vertical moving module 420 is an existing structure. The vertical moving module 420 includes a motor, gears, chains and lead screws. The motor drives the gears and chains to drive the lifting frame 4 which is fixedly connected to the lead screw, thereby realizing the lifting of the lifting frame 4. It can be used in conjunction with the lifting frame 4 and the feeding assembly to realize the distribution and placement of dry powder cylinders. When the vertical moving module 420 drives the lifting frame 4 to move, the four first limit rods 410 slide synchronously on the fixed base 3. The four first limit rods 410 will limit the horizontal position of the lifting frame 4, so that the lifting frame 4 always maintains a stable vertical movement trajectory during the rising process, and avoids the position deviation of the lifting frame 4 due to horizontal offset.

[0025] Furthermore, since one row of fixing rings 110 is smaller than the other row of fixing rings 110, it conforms to the shape of the dry powder cylinder, which is narrower at the top and wider at the bottom. This allows the dry powder cylinder to move stably on the first counting conveyor belt 1 under the guidance of the arc-shaped inner wall of the fixing rings 110, preventing the dry powder cylinder from swaying. After the dry powder cylinder enters the packaging box through the vertical moving module 420 and the feeding assembly, the front-end raised box pressing rod 220, supported by the fixing rod 210, slightly presses down on the two sides of the packaging box to prevent the sides of the packaging box from obstructing the filling of the feeding assembly. After a complete filling is completed, the second counting conveyor belt 2 starts again, transporting the packaging box filled with dry powder cylinder to the next process. At the same time, a new empty packaging box is transported to the fixed seat 3, and the above counting and packing process is repeated.

[0026] like Figures 4 to 12 As shown, limit holes are provided at the four top corners of the first feeding rack 501. Second limit rods 510 penetrate through the interior of each of the four limit holes. The lower ends of the four second limit rods 510 are fixedly connected to a lifting plate 520. A feeding plate 530 is provided at the bottom of the lifting plate 520. The top outer wall of the feeding plate 530 is in contact with the bottom outer wall of the lifting plate 520. A transmission rod 540 is fixedly connected to the center of the top of the feeding plate 530. The top end of the transmission rod 540 penetrates through the first feeding rack 501 and the lifting plate 520. 0. The position where the transmission rod 540 contacts the lifting plate 520 is provided with a limiting ring 550. The lifting plate 520 has a fixing groove that matches the limiting ring 550. The limiting ring 550 is rotatably connected to the lifting plate 520 in the fixing groove. When the rotating rod 540 drives the feeding plate 530 to move in the vertical direction, it will drive the lifting plate 520 to move together. When the rotating rod 540 drives the feeding plate 530 to rotate, the lifting plate 520 will not rotate with the rotating rod 540 and the feeding plate 530.

[0027] The other side wall of the lifting frame 4 is provided with a lifting transmission groove 430. The lifting transmission groove 430 is shaped as an isosceles trapezoid. A sliding wheel 440 is slidably connected to the inner wall of the lifting transmission groove 430. One side of the sliding wheel 440 is fixedly connected to the lifting plate 520.

[0028] like Figure 7 and Figure 10 As shown, a transmission gear plate 541 is fixedly connected to the top of the transmission rod 540, and a fitting plate 542 is fixedly connected to the top of the transmission gear plate 541. A transverse sliding groove adapted to the fitting plate 542 is opened on the inner surface of the top of the lifting frame 4. Four levers 543 are fixedly connected at equal intervals on one side of the transverse sliding groove. The levers 543 are meshed with the transmission gear plate 541. Four limiting plates 544 are fixedly connected to the outer wall of the end of the transmission rod 540 near the transmission gear plate 541. The four limiting plates 544 are arranged in a ring array about the outer wall of the transmission rod 540. The limiting plates 544 penetrate the first feeding frame 501.

[0029] The support frame 503 at the other end of the first feeding frame 501 and the second feeding frame 502 is slidably connected to the sliding rail 560, and both sliding rails 560 are fixedly connected to the lifting frame 4.

[0030] The bottom outer walls of both the feeding plate 530 and the second feeding rack 502 are provided with two rows of vacuum suction cups 570. The two rows of vacuum suction cups 570 are symmetrically arranged about the central axis of the feeding plate 530 and the second feeding rack 502. There are five vacuum suction cups 570 in each row at the bottom of the feeding plate 530 and six vacuum suction cups 570 in each row at the bottom of the second feeding rack 502. The vacuum suction cups 570 closer to the first counting conveyor belt 1 are higher than the vacuum suction cups 570 closer to the second counting conveyor belt 2.

[0031] It should be noted that the support frame 503, which is fixedly connected to the first feeding frame 501, is fixed at the higher end of the transmission belt 504, while the support frame 503, which is fixedly connected to the second feeding frame 502, is fixed at the lower end of the transmission belt 504. This facilitates the alternating feeding of materials by the first feeding frame 501 and the second feeding frame 502. Under the action of the laser sensor, the first counting conveyor belt 1 pauses after detecting five or six counts of the dry powder cylinder. When the dry powder cylinder counts to six, the stepper motor 506 starts the transmission wheel 505, which drives the transmission belt 504 to rotate on the lifting frame 4, moving the second feeding frame 502 above the first counting conveyor belt 1. Then, the vertical moving module... Group 420 sends the second feeding rack 502 to the top of the dry powder cylinder for gripping and positioning. Then, the second feeding rack 502 rises and resets through the vertical moving module 420, and under the action of the feeding component, transports six dry powder cylinders to the second counting conveyor belt 2. At this time, the first counting conveyor belt 1 has already transported five dry powder cylinders to the front of the fixed seat 3 and stopped with the cooperation of the controller. The gripping method of the second feeding rack 502 is the same as the gripping method of the feeding plate 530. When the second feeding rack 502 has placed the gripped six dry powder cylinders into the carton under the action of the vertical moving module 420, completing the first layer of laying inside the carton, the feeding plate 530 has just gripped five dry powder cylinders.

[0032] It should be noted that the rotational speed of the stepper motor 506 is matched with the speed at which the first counting conveyor belt 1 conveys the dry powder cylinders. Furthermore, whenever the first counting conveyor belt 1 conveys a group of five or six dry powder cylinders to the front of the fixed seat 3, the stepper motor 506 stops rotating. After the feeding plate 530 and the second feeding rack 502 take in and release the dry powder cylinders, the stepper motor 506 reverses once. This helps to ensure that the feeding and boxing speed matches the loading speed. In addition, the height difference design between the feeding plate 530 and the two rows of vacuum suction cups 570 in the second counting feeding rack can match the size difference between the two rows of fixed rings 110 of the first counting conveyor belt 1, so that the two rows of vacuum suction cups 570 can stably grip the dry powder cylinders that are narrow at the top and wide at the bottom.

[0033] Simultaneously, during the movement of the feeding plate 530, as the transmission belt 504 runs, the sliding wheel 440, fixedly connected to the lifting plate 520, slides from the lowest end to the highest end of the lifting transmission groove 430. Since the limiting ring 550 of the transmission rod 540 is embedded inside the lifting plate 520, the lifting plate 520 and the feeding plate 530 are used in combination. The lifting plate 520 drives the feeding plate 530 to rise simultaneously. When it rises to the highest point, the second limiting rod 510 slides upward on the first feeding frame 501. The fitting plate 542 at the top of the transmission rod 540 is embedded in the transverse sliding groove of the lifting frame 4. In this way, the first lifting frame 4 and the second lifting frame 4 achieve rapid vertical misalignment when they intersect, preventing the first feeding frame 501 and the second feeding frame 502 from colliding during operation, and ensuring that the feeding plate 530 and the dry powder cylinder move horizontally. When the first feeding frame 501 and the second feeding frame 502 are misaligned, the sliding wheel 440 slides from the highest end of the lifting transmission groove 430 back to the lowest end, driving the lifting plate 520 and the feeding plate 530 down to the initial height, preparing for the next feeding. In addition, a sliding rail 560 is provided on one side of the moving path of the first feeding frame 501 and the second feeding frame 502, which can effectively limit the lateral displacement of the first feeding frame 501 and the second feeding frame 502, further improving the stability and accuracy of the feeding and packing process. In addition, when the feeding plate 530 rises, the four second limit rods 510 limit the vertical horizontal position of the lifting plate 520, so that the lifting plate 520 always maintains a stable vertical movement trajectory during the rising process, avoiding positional deviation when the feeding plate 530 grabs the dry powder cylinder due to horizontal displacement.

[0034] Specifically, when the transmission rod 540 is fitted into the transverse slide groove of the lifting frame 4, the transmission tooth plate 541 at the end of the transmission rod 540 simultaneously contacts the first lever 543. Subsequently, the transmission tooth plate 541 continues to slide, and the lever 543 engages with the transmission tooth plate 541 and moves the transmission tooth plate 541. The four levers 543 can just make the transmission tooth plate 541 rotate 180°. At the same time, the transmission rod 540, which is fixedly connected to the transmission tooth plate 541, carries the feeding plate 530 and rotates horizontally by 180°. The five dry powder cylinders grabbed by the feeding plate 530 immediately reverse. In this way, the opening directions of the first layer and the second layer of dry powder cylinders are staggered in opposite directions, forming a stable interlayer interlocking structure. This avoids the problem of dry powder cylinders easily tipping over and shaking in traditional double-layer stacking, and improves the overall stability of the dry powder cylinder stack after packaging.

[0035] It should be noted that the length of the limiting plate 544 is adapted to the vertical distance between the lowest and highest points of the lifting transmission groove 430. When the lifting plate 520 moves from the lowest point to the highest point of the lifting transmission groove 430, the limiting plate 544 simultaneously disengages from the first feeding frame 501, so that the feeding plate 530 can rotate horizontally. After the feeding plate 530 rotates horizontally, when it descends under the action of the lifting transmission groove 430, the limiting plate 544 quickly enters the interior of the first feeding frame 501, so that the feeding plate 530 can be positioned by the first feeding frame 501, ensuring that the feeding plate 530 maintains its adjusted position during the descent, and avoiding inaccurate placement of the dry powder cylinder.

[0036] like Figures 9 to 12 As shown, each vacuum suction cup 570 is fixedly connected to a movable tube 580 at its top end. The movable tube 580 extends into the inside of the feeding plate 530, and a return spring 590 is sleeved on the outer wall of the movable tube 580.

[0037] The top outer walls of the two rows of movable tubes 580 at the bottom of the feeding plate 530 are all nested with fixed tubes 581. Multiple fixed tubes 581 are provided, and a pusher plate 582 is fixedly connected to all of them. The feeding plate 530 has multiple push grooves 583 that match the size of the pusher plate 582. The spacing between each push groove 583 is half the spacing between the two vacuum suction cups 570. The pusher plate 582 is slidably connected to the feeding plate 530. Positioning grooves 584 are provided on both sides of the feeding plate 530, and both ends of the positioning grooves 584 are... The smoothed groove walls are arc-shaped and smoothed. The positioning groove 584 is equipped with a roller assembly 585. The outer surface of the roller assembly 585 is in contact with the outer surface of the push plate 582. The roller assembly 585 consists of an inclined plate and a roller rotatably connected to the lower end of the inclined plate. A slide rod 586 is fixedly connected to the top of the inclined plate of the roller assembly 585. The end of the slide rod 586 is fixedly connected to the inside of the lifting plate 520. A telescopic spring 587 is fixedly connected between the end of the slide rod 586 and the lifting plate 520. The telescopic spring 587 is sleeved on the outer surface of the slide rod 586.

[0038] It should be noted that the vacuum suction cups 570 are all existing structures. Each row of vacuum suction cups 570 can be equipped with a pump body and an air pipe. The pump body enables the vacuum suction cups 570 to load and unload the dry powder cylinder. Since this structure is existing technology, it will not be described in detail and is not shown in the accompanying drawings of the instruction manual. However, the corresponding assembly is required when actually reproducing this device.

[0039] Specifically, when the transmission rod 540 drives the feeding plate 530 to rotate and moves in the direction of the second counting conveyor belt 2, since the lifting plate 520 and the roller assembly 585 remain stationary, the telescopic spring 587 always provides a lateral elastic force to the roller assembly 585. The telescopic spring 587 can drive the slide rod 586 to slide horizontally on the lifting plate 520 through its own elastic deformation, so that the surface of the roller assembly 585 is always in close contact with the surface of the feeding plate 530. Furthermore, the shape of the positioning groove 584 is... The feed plate 530 is deep in the middle and shallow at both ends. When the feed plate 530 rotates, it causes the positioning grooves 584 at both ends to switch positions. The positioning groove 584 at the other end will then contact the roller assembly 585, causing the rollers of the roller assembly 585 to contact the push plate 582 and press it. This pushes the push plate 582 and the two rows of vacuum suction cups 570 installed inside it from one end of the push groove 583 to the other end, so that the feed plate 530 can place the five dry powder cylinders between the six dry powder cylinders in the box. At this time, the end of the push plate 582 that is not in contact with the rollers is in a state of protruding from the positioning groove 584, so that the feed plate 530 can be rotated and reset later, allowing the rollers to push the push plate 582 to move and reset. At this point, the five dry powder canisters perfectly fill the five gaps between the original six dry powder canisters (the gaps are created when two dry powder canisters are joined together; essentially, they are natural gaps formed by the geometric characteristics of a regularly arranged cylindrical object, also called columnar arrangement gaps, and the outer surface of the dry powder canisters is cylindrical). This makes the dry powder canisters inside the box more compact and increases their number. It is also the optimal close-packing method for cylindrical dry powder canisters in a rectangular box, which not only meets the medical protection requirements of hemodialysis dry powder canisters (anti-squeezing, anti-shaking, and sealing) but also improves packaging and logistics efficiency.

[0040] After the feeding plate 530 completes the second layer of material inside the box, under the action of the vertical moving module 420, the lifting plate 520 returns to its original position and moves towards the first counting conveyor belt 1 under the feeding assembly. During the reversal process, the roller group 585 squeezes the pushing plate 582 again, so that the pushing plate 582 returns to its initial state, thus preparing for the next adsorption and handling of dry powder cylinders. This realizes the orderly and efficient counting and packing operation of dry powder cylinders from the feeding plate 530 to the box. Through this intermittent pushing method, each row of vacuum suction cups 570 can accurately and orderly transport the dry powder cylinders one by one to the subsequent packing station, ensuring the continuity and accuracy of the counting and packing process. At the same time, existing dialysis dry powder cylinders are usually stacked up to three layers to avoid collapse due to unstable center of gravity or insufficient packaging pressure. Therefore, this application only places two layers to ensure safe and reasonable placement, which meets the placement requirements.

[0041] Meanwhile, when the feeding plate 530 and the second feeding rack 502 are sucking up and dropping the dry powder cylinder, the movable tube 580 provides a certain buffer space for the suction and dropping operation, so as to avoid damage to the surface of the dry powder cylinder due to rigid contact during the suction and dropping process. One end of the movable tube 580 is fixedly connected to the vacuum suction cup 570, and the other end is movably connected to the feeding plate 530 through the return spring 590. When the vacuum suction cup 570 contacts and sucks up the dry powder cylinder, the movable tube 580 can make slight extension and retraction adjustments according to the actual position of the dry powder cylinder to ensure that the suction cup is in close contact with the surface of the dry powder cylinder and improve the stability of the suction. This buffer design not only protects the integrity of the dry powder cylinder, but also further ensures the smoothness and reliability of the entire counting and packing process.
