The bottom end of the first adsorption part 40 is provided with a guide part, and the guide part is used to enter the packaging bag and cooperate with the opening guide of the packaging bag.

[0032] By applying the technical solution of the utility model, the infusion patch can be automatically placed in the packaging bag through the infusion patch bag feeding mechanism, which reduces manual intervention and reduces the labor intensity of the staff. Specifically, the loading is carried out through the loading device 10; the transfer part 30 drives the first adsorption part 40 to move to a position close to the loading device 10, and the first adsorption part 40 adsorbs the infusion patch; then, the transfer part 30 drives the first adsorption part 40 to move to the bag opening device 20; the bag opening device 20 opens the packaging bag, the bottom end of the first adsorption part 40 faces the packaging bag and extends the guide part into the packaging bag, and the first adsorption part 40 releases the infusion patch into the packaging bag, completing a complete loading process. After that, the above process is repeated to realize continuous automatic loading. The setting of this device has a high degree of automation, reduces manual intervention, and is easy to operate. In addition, the setting of the guide part can prevent the adsorption part from causing unnecessary damage to the packaging bag and the material in the packaging bag when entering the packaging bag, thereby protecting the integrity of the packaging bag.

[0033] Specifically, after the bag opening device 20 opens the packaging bag, the top of the packaging bag forms an open structure. The first adsorption portion 40 is a plate-like structure, and the plate surface of the first adsorption portion 40 is perpendicular to the moving direction of the first adsorption portion 40. The first adsorption portion 40 includes a main body section 41 and a guide section 42 that are connected to each other. One side of the main body section 41 has a first adsorption surface. The guide section 42 is located below the main body section 41. Along the direction from the main body section 41 to the guide section 42, the distance between the two side walls of the guide section 42 gradually decreases. That is, the guide section 42 forms a guide portion. With such a configuration, its structure is simple, and when the first adsorption portion 40 is extended into the packaging bag, the guide section 42 plays a guiding role, which facilitates the first adsorption portion 40 to be extended into the packaging bag.

[0035] In some embodiments of the present case, a moving wheel is installed at the bottom of the transfer part 30 , and the first driving part 50 is disposed on the transfer part 30 and is drivingly connected to the moving wheel of the transfer part 30 .

[0036] In the embodiment of the present solution, the infusion bag sticking mechanism further includes a support frame 80, the transfer unit 30 is movably arranged on the support frame 80, and the first driving unit 50 is arranged on the support frame 80 and is drivingly connected to the transfer unit 30. In this arrangement, the transfer unit 30 and the first driving unit 50 are integrated into the support frame 80, thereby improving the compactness of the structure of the present device.

[0037] In order to ensure the compactness of the structure of the device, the first driving unit 50 , the transfer unit 30 , the first adsorption unit 40 and the bag opening device 20 are all located on the same side of the support frame 80 .

[0038] Specifically, the transfer unit 30 is movably disposed on the support frame 80 along a horizontal direction.

[0039] In some embodiments of the present solution, the support frame 80 includes a vertically arranged fixed plate 81, the transfer portion 30 is slidably connected to the fixed plate 81, and the sliding direction of the transfer portion 30 is horizontal.

[0040] This solution does not limit the sliding manner of the transfer portion 30 relative to the fixed plate 81.

[0041] In some embodiments of the present scheme, a first slide rail 811 is provided on one of the fixed plate 81 and the transfer part 30, and a first slide groove 812 is provided on the other of the fixed plate 81 and the transfer part 30. The first slide rail 811 and the first slide groove 812 are guided and matched, and the first slide rail 811 extends in the horizontal direction.

[0042] like Figure 2 As shown, in this embodiment, a first slide rail 811 is provided on one side of the fixed plate 81 close to the transfer portion 30 , and a first slide groove 812 is provided on one side of the transfer portion 30 close to the fixed plate 81 .

[0044] This solution does not limit the specific structure of the first driving part 50.

[0045] In the embodiment of this solution, the first driving part 50 is a first horizontal driving cylinder.

[0046] In some embodiments of the present solution, the first driving unit 50 includes a driving cylinder.

[0047] In some embodiments of the present scheme, the first driving part 50 includes a motor, a lead screw and a nut that cooperate with each other, wherein the lead screw is rotatably arranged on a fixed plate 81, the lead screw extends in a horizontal direction, the nut is threadedly connected to the lead screw, the transfer part 30 is arranged on the nut, the motor is arranged on the fixed plate 81, and the motor is driven and connected to the lead screw to rotate, and the rotation of the lead screw drives the nut to drive the transfer part 30 to move.

[0048] In other embodiments of the present solution, the first adsorption part 40 can be arranged to have a constant height relative to the support frame 80, and the bag opening device 20 can be arranged to rise or fall relative to the transfer part 30. Such an arrangement can further improve the automation level of the present device, so that after the first adsorption part 40 places the infusion patch in the packaging bag, the first adsorption part 40 is automatically separated from the packaging bag.

[0049] In the embodiment of this solution, the height of the first adsorption portion 40 relative to the support frame 80 is adjustable.

[0050] Specifically, the infusion bag insertion mechanism also includes a height adjustment component 60, which is arranged between the transfer part 30 and the first adsorption part 40. The height adjustment component 60 adjusts the position of the first adsorption part 40 relative to the transfer part 30 in the height direction so that the bottom end of the first adsorption part 40 extends into or out of the packaging bag.

[0051] like Figures 1 to 3As shown, in the embodiment of the present scheme, the height adjustment assembly 60 includes a first lifting cylinder 61 and a lifting plate 62, wherein the lifting plate 62 is movably arranged on the transfer part 30 along the height direction, and the first adsorption part 40 is arranged on the lifting plate 62; the first lifting cylinder 61 is arranged on the transfer part 30, and the first lifting cylinder 61 is drivingly connected to the lifting plate 62 to lift the lifting plate 62. When the height of the first adsorption part 40 needs to be adjusted, the lifting plate 62 is driven to be lifted and lowered by the first lifting cylinder 61, and the lifting and lowering of the lifting plate 62 drives the first adsorption part 40 to be lifted and lowered. Such a configuration can improve the smoothness and convenience of adjusting the height of the first adsorption part 40.

[0052] Furthermore, the height adjustment assembly 60 also includes a second lifting cylinder 63, and the second lifting cylinder 63 includes a first seat body and a first piston rod that slide with each other, the first seat body is arranged on the lifting plate 62, the first piston rod is located below the first seat body, the first piston rod is telescopic in the vertical direction, the first adsorption part 40 is arranged on the first piston rod, and the first adsorption part 40 is arranged on the lifting plate 62 through the second lifting cylinder 63. The above arrangement enables the telescopic movement of the second lifting cylinder 63 to be directly transmitted to the first adsorption part 40, thereby realizing the adjustment of the height of the first adsorption part 40. In this solution, the first lifting cylinder 61 and the second lifting cylinder 63 provide two independent adjustment means, which can be used separately or simultaneously to achieve more precise height control. In addition, this two-level adjustment mechanism enables the system to adapt to packaging bags of different heights and sizes, thereby improving the flexibility and versatility of the automated production line.

[0053] Furthermore, the second lifting cylinder 63 and the transfer part 30 are respectively located on both sides of the lifting plate 62. Such an arrangement can improve the compactness and rationality of the structure of the device.

[0054] like Figure 2 and Figure 3 As shown, in the embodiment of this solution, a second slide rail 31 is provided on one side of the transfer part 30 close to the lifting plate 62, and the second slide rail 31 extends in the vertical direction. A second slide groove is provided on one side of the lifting plate 62 close to the transfer part 30, and the second slide groove extends in the vertical direction. The second slide rail 31 and the second slide groove are slidably matched. Such a configuration can improve the smoothness and stability of the movement of the lifting plate 62.

[0055] In some embodiments of the present scheme, the device also includes a second guide rod and a second bearing component that guide and cooperate with each other, wherein the second guide rod is arranged on one of the transfer part 30 and the lifting plate 62, and the second bearing component is arranged on the other of the transfer part 30 and the lifting plate 62.

[0056] like Figure 1 , Figure 2 and Figure 4As shown, specifically, the loading device 10 includes a storage portion 11, a mounting seat 12 and a second adsorption portion 13. The storage portion 11 has a storage cavity and a discharge port that are interconnected; the mounting seat 12 is located downstream of the storage portion 11, and the mounting seat 12 is located upstream of the transfer portion 30; the second adsorption portion 13 is rotatably arranged on the mounting seat 12, and the extension direction of the rotating shaft of the second adsorption portion 13 is perpendicular to the discharge direction of the discharge port. Such an arrangement can facilitate automatic loading, and the infusion patch located in the storage cavity is adsorbed by the second adsorption portion 13, which is more convenient to operate and can reduce or avoid the possibility of damage to the infusion patch.

[0057] It can be understood that the second adsorption part 13 is provided with a second adsorption surface, and the second adsorption part 13 is rotatably arranged on the mounting seat 12, so as to ensure that when the second adsorption part 13 adsorbs the infusion patch in the material storage part 11, the second adsorption surface faces the discharge port. Thereafter, when the first adsorption part 40 needs to adsorb the infusion patch from the second adsorption part 13, the second adsorption part 13 is rotated to face the second adsorption surface thereof toward the first adsorption surface of the first adsorption part 40.

[0058] In some embodiments of the present solution, the bag opening device 20 and the material storage part 11 are respectively located at both ends of the moving direction of the transfer part 30, and the material outlet is arranged on the side of the material storage part 11, and the material outlet is arranged toward the first adsorption part 40. In this way, the extension direction of the rotation axis of the second adsorption part 13 is the vertical direction.

[0059] In the embodiment of the present scheme, the discharge port is located below the material storage part 11, and the extension direction of the rotation axis of the second adsorption part 13 is the horizontal direction. That is, when the second adsorption part 13 needs to adsorb the infusion patch in the material storage cavity, the second adsorption surface of the second adsorption part 13 is set upward; when the first adsorption part 40 needs to adsorb the infusion patch on the second adsorption part 13, the second adsorption surface of the second adsorption part 13 faces the first adsorption part 40, that is, the second adsorption surface of the second adsorption part 13 is in a vertical state. With such a configuration, the infusion patch has a tendency to move downward under the action of gravity, which facilitates the second adsorption part 13 to adsorb the infusion patch.

[0060] Furthermore, the distance between the second adsorption part 13 and the discharge port in the height direction is adjustable. Such a configuration can improve the smoothness and stability of the second adsorption part 13 adsorbing the infusion patch. Moreover, the above configuration can facilitate the rotation of the second adsorption part 13 and reduce the possibility of interference between the second adsorption part 13 and the storage part 11 during the rotation process.

[0061] Specifically, the infusion bag-feeding mechanism includes a base 71 and a lifting seat 72. The lifting seat 72 is escalably arranged on the base 71, and the mounting seat 12 is arranged on the lifting seat 72. In this arrangement, the lifting seat 72 is raised and lowered to drive the mounting seat 12 and the second adsorption part 13 to rise and fall synchronously, thereby improving the convenience of the lifting process of the second adsorption part 13.

[0062] In the embodiment of the present solution, the infusion bag insertion mechanism further comprises a third lifting cylinder 73 , which is disposed on the base 71 , and is drivingly connected to the lifting seat 72 to enable the lifting seat 72 to be raised and lowered.

[0063] In order to make the device suitable for different environmental sites, in this solution, the lifting seat 72 extends in the horizontal direction, and the extension direction of the lifting seat 72 is perpendicular to the moving direction of the first adsorption part 40. The lifting seat 72 has a head end and a tail end arranged opposite to each other in the horizontal direction. The transfer part 30 drives the first adsorption part 40 to move back and forth between the tail end and the bag opening device 20. The storage part 11 is arranged at the head section position of the lifting seat 72, and the mounting seat 12 drives the second adsorption part 13 to move back and forth between the head section and the tail end of the lifting seat 72. Such an arrangement can make the device suitable for different work sites, thereby improving the adaptability of the device.

[0064] In the embodiment of the present scheme, the material storage part 11 includes a bearing frame 111 and a plurality of limiting columns 112. Among them, the bearing frame 111 forms a material outlet; the plurality of limiting columns 112 are all located above the bearing frame 111, the plurality of limiting columns 112 extend in the vertical direction, and the plurality of limiting columns 112 are mutually parallel, and the plurality of limiting columns 112 are distributed at intervals along the circumference of the bearing frame 111, and a material storage cavity is formed between the bearing frame 111 and the plurality of limiting columns 112. Such a configuration can facilitate the placement of the infusion patch and facilitate the adsorption of the infusion patch by the second adsorption part 13.

[0065] Furthermore, the material storage part 11 further includes a weight portion 113, which is used to press the infusion patch installed in the limiting column 112. In this way, the weight portion 113 applies a downward force to the infusion patch, so that the infusion patch has a tendency to move downward, which can further improve the smoothness of the second adsorption part 13 adsorbing the infusion patch.
