[0002] In the medical supplies production system, infusion bags are the key carriers of clinical infusion therapy, and the importance of their packaging cannot be underestimated. For a long time, the packaging of infusion bags has mainly relied on manual labor. In actual operation, workers need to stand beside the assembly line, repeatedly bending over and reaching out to grab the infusion bags for a long time, and then perform a series of complex processes such as folding, bagging, and sealing. Each action requires not only precision and accuracy, but also a certain speed to maintain the production rhythm. However, manual operation has many disadvantages that are difficult to overcome.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example: Figure 1 —— Fig.12 The automatic packaging machine for infusion bags shown comprises: Bottom plate 1.

[0030] Material guiding mechanism 2: The material guiding mechanism 2 is installed on the bottom plate 1, and the material guiding mechanism 2 includes a material storage frame 21, and the material storage frame 21 is used to store the infusion bags to be packaged.

[0031] Feeding mechanism 3; the feeding mechanism 3 is mounted on the base plate 1, and the feeding mechanism 3 includes a material taking component and a feeding component, and the material taking component is used to take out the infusion bag in the material storage frame 21 and place it in the feeding component.

[0032] Packaging mechanism 4: The packaging mechanism 4 is installed on the base plate 1, and the packaging mechanism 4 is used to package and seal the infusion bag.

[0033] like Figure 1 As shown, a material guiding mechanism 2, a feeding mechanism 3 and a packaging mechanism 4 are provided on the bottom plate 1. The upper part of the material storage frame 21 in the material guiding mechanism 2 is in an open state, and the infusion bag to be packaged can be placed in the material storage frame 21, and then the infusion bag is gradually taken out from the material storage frame 21 by the cylinder 33 in the feeding mechanism 3 and placed between two packaging films 31, and then transported to the position of the packaging mechanism 4 through the packaging film 31 to complete the packaging.

[0034] The material guiding mechanism 2 also includes a vibration plate 22, which is rotatably mounted on the material storage frame 21, on which one end of a connecting rod 25 is rotatably mounted, and the other end of the connecting rod 25 is slidably matched with a rotating plate 24, which is rotatably mounted on the material storage frame 21, and an outer ring sleeve of the connecting rod 25 is provided with a return spring 26, and the two ends of the return spring 26 are respectively connected to the vibration plate 22 and the rotating plate 24, and a vibrator 23 is mounted on the vibration plate 22.

[0035] The material storage frame 21 is provided with a material discharge port 211 and two symmetrically arranged material guide plates 212 . The material guide plates 212 are located inside the material storage frame 21 and above the material discharge port 211 .

[0036] like Figures 1 to 4 As shown, the discharge port 211 provided on the material storage frame 21 is used to take out the infusion bag placed in the material storage frame 21, and the two material guide plates 212 provided inside the material storage frame 21 are used to correct the position of the infusion bag. When placing the infusion bag in the material storage frame 21, align the end of the infusion bag with the plastic port between the two material guide plates 212, so that the position of the infusion bag can be preliminarily corrected. Of course, during the placement process, it is difficult to ensure that the wide surface of the plastic bag remains parallel to the ground. At this time, the position of the infusion bag needs to be fine-tuned. Specifically, the vibrator 23 fixedly mounted on the vibration plate 22 is started, and the vibration plate 22 is driven to rotate by the vibrator 23. Since the vibration plate 22 is rotatably mounted on the material storage frame 21, the rotation direction of the vibration plate 22 is close to the material guide plate 212 or close to the rotating plate 24. In this way, when the vibration plate 22 vibrates and rotates in the direction close to the material guide plate 212, the vibration of the infusion bag itself can be caused. On the one hand, it is convenient for the infusion bag to move downward along the material guide plate 212, and on the other hand, the position of the infusion bag is corrected to prevent the final position of the infusion bag from being not parallel to the ground, affecting the subsequent packaging process. When the vibration plate 22 rotates, the rotating plate 24 will be driven to rotate by the reset spring 26. In this process, the connecting rod 25 will slide along the rotating plate 24. The role of the rotating plate 24, the connecting rod 25 and the reset spring 26 is to stabilize and assist in resetting the vibration plate 22.

[0037] The material picking assembly includes a cylinder 33 fixedly mounted on the base plate 1, a piston rod 34 is coaxially slidably mounted inside the cylinder 33, a support rod 35 is coaxially fixedly mounted inside the piston rod 34, a connecting head 39 is fixedly mounted on the support rod 35, and the support rod 35 is slidably matched with the guide plate 36, and two symmetrically arranged clamping jaws 37 are rotatably mounted on the connecting head 39, and the clamping jaws 37 are slidably matched with the guide plate 36.

[0038] A guide groove 361 is provided on the guide plate 36, and the guide groove 361 is slidably matched with the clamping claw 37. An inclined surface 371 is provided on the end of the clamping claw 37 away from the guide plate 36. A return spring 2 38 is provided between the guide plate 36 and the connecting head 39, and the return spring 2 38 is sleeved on the outer ring of the support rod 35.

[0039] like Figures 5 to 7 As shown, when the infusion bag is taken out from the material storage frame 21, the cylinder 33 is started, and the piston rod 34 inside the cylinder 33 slides along the inside of the cylinder 33, and the piston rod 34 drives the support rod 35 and the clamping claw 37 to pass through the two packaging films 31 to move to the side close to the material storage frame 21, and then the clamping claw 37 passes through the discharge port 211 and enters the material storage frame 21, and the two clamping claws 37 contact the plastic shell of the infusion bag and clamp the plastic mouth of the infusion bag. It should be noted that when the clamping claw 37 is close to the plastic mouth of the infusion bag, the inclined surface 371 on the clamping claw 37 first contacts the plastic mouth, and then due to the existence of the inclined surface 371, the plastic mouth will not limit the movement of the clamping claw 37, and at the same time due to the effect of the inclined surface 371, the two clamping claws 37 rotate on the connector 39, so that the two clamping claws 37 continue to move and clamp the plastic mouth of the infusion bag. When the clamp 37 clamps the infusion bag, the clamp 37 rotates relative to the connector 39 and the clamp 37 slides with the guide plate 36 . Therefore, during this process, the clamp 37 slides along the guide groove 361 , and the movement state of the guide groove 361 is sliding along the support rod 35 .

[0040] After the clamping jaws 37 complete the clamping, the piston rod 34 contracts, causing the support rod 35, the clamping jaws 37 and the infusion bag to move toward the side close to the cylinder 33. When the guide plate 36 contacts the end of the cylinder 33 close to the material storage frame 21, the port of the cylinder 33 will support the guide plate 36. At this time, the guide plate 36 no longer moves. Because the guide plate 36 and the support rod 35 slide in cooperation, the piston rod 34 and the support rod 35 are still contracted into the cylinder 33. The connecting head 39 is close to the guide plate 36 and compresses the reset spring 2 38, so that the clamping jaws 37 continue to rotate relative to the connecting head 39, that is, the distance between the two clamping jaws 37 and the end of the infusion bag will continue to increase, so that the infusion bag is no longer clamped, and the infusion bag falls onto the packaging film 31 located below.

[0041] The feeding assembly includes two symmetrically arranged packaging films 31, one end of the packaging film 31 is wrapped around the base plate 1, and the other end of the packaging film 31 is connected to the packaging mechanism 4. The two packaging films 31 are respectively slidably matched with two conveying rollers 32, and the conveying rollers 32 are rotatably installed on the base plate 1.

[0042] like Figure 1 As shown, the end of the packaging film 31 close to the packaging mechanism 4 will move toward the packaging mechanism 4, so that the infusion bag falling on the packaging film 31 gradually approaches the packaging mechanism 4 and is packaged by the packaging mechanism 4. In this process, the conveying roller 32 guides the packaging film 31. It should be noted that those skilled in the art can imagine that the cylinder 33 is started intermittently, so that the clamping claw 37 intermittently takes the infusion bag out of the storage frame 21 and places it on the packaging film 31, and then the packaging is completed by the packaging mechanism 4.

[0043] The packaging mechanism 4 includes a cutting part 42 installed on the base plate 1, the cutting part 42 includes two groups of symmetrically arranged pressing components, the pressing components include two symmetrically arranged clamping tables 421, there is a gap between the clamping tables 421, and the upper and lower layers of packaging film 31 are slidably matched with the two groups of pressing components; the cutting part 42 also includes two groups of edge sealing components, the edge sealing components include two symmetrically arranged clamping wheels 422, and a cylindrical gear 423 is coaxially fixedly installed on one clamping wheel 422 in each edge sealing component, and the cylindrical gear 423 is connected to the power part 41.

[0044] like Figure 8 , Fig. 9 As shown, the cylindrical gear 2 423 is driven to rotate by the power unit 41, so that the cylindrical gear 2 423 can drive the clamping wheel 422 to rotate, so that the upper and lower clamping wheels 422 convey the packaging film 31 forward, and at the same time, the clamping wheels 422 are heated, and the edges (sides) of the two packaging films 31 are sealed by the clamping wheels 422. In this process, the clamping table 421 plays a guiding role.

[0045] The power unit 41 includes a motor 411 fixedly mounted on a vertical frame 47, the vertical frame 47 is fixedly mounted on the base plate 1, a rotating shaft 412 is fixedly mounted on the output shaft of the motor 411, one end of a belt assembly 413 is connected to the rotating shaft 412, the other end of the belt assembly 413 is mounted on a central shaft 415, the central shaft 415 is rotatably mounted on a clamping table 421, and a cylindrical gear 1 414 is fixedly mounted on both ends of the central shaft 415, and the cylindrical gear 1 414 is meshed with the cylindrical gear 2 423.

[0046] The packaging mechanism 4 also includes two symmetrically arranged rotating rods 45, one end of which is rotatably mounted on the rotating shaft 412, and the other end of the rotating rod 45 is rotatably connected to a pressing knife 46, which is slidably mounted between two vertical frames 47, and is provided with a plurality of spaced bosses 461 and grooves 462.

[0047] The packaging mechanism 4 further comprises a conveyor belt 1 43 and a conveyor belt 2 44, and the conveyor belt 1 43 and the conveyor belt 2 44 are used to convey the packaged infusion bags.

[0048] like Figures 8 to 12 As shown, during the packaging process, the motor 411 is started, so that the output shaft of the motor 411 drives the rotating shaft 412 to rotate on the vertical frame 47, the rotating shaft 412 drives the belt assembly 413 to rotate, and the belt assembly 413 drives the central shaft 415 to rotate, so that the cylindrical gear 1 414 on the central shaft 415 can drive the cylindrical gear 2 423 to rotate. The belt assembly 413 includes two pulleys and a belt, and the two pulleys are fixedly mounted on the rotating shaft 412 and the central shaft 415 respectively.

[0049] In addition, during the rotation of the rotating shaft 412, the rotating shaft 412 drives the rotating rod 45 to reciprocate up and down, and the pressing knife 46 connected to the rotating rod 45 will reciprocate up and down along the vertical frame 47. During the downward movement of the pressing knife 46, the lower part of the pressing knife 46 will contact the packaging film 31, and the two packaging films 31 will be pressed together by the pressing knife 46. In addition, since the bosses 461 and the grooves 462 are arranged at intervals below the pressing knife 46, there will be gaps (i.e., through holes are arranged at intervals) on the packaging film 31 after pressing, and the purpose of this is to facilitate the individual removal of the packaged infusion bag at a later time.

[0050] The packaged infusion bag is transported away by conveyor belt 1 43 and conveyor belt 2 44. For those skilled in the art, it is conceivable to power conveyor belt 1 43 and conveyor belt 2 44 to complete the transportation, and it is also conceivable to collect the packaged infusion bag.
