[0034] That is, the bag-supporting device provided in the embodiment of the utility model drives the bag-supporting auxiliary blocks 120 extending into the opening of the packaging bag to move away from each other through the first driving member 111, thereby expanding the opening, and then inflates the packaging bag through the blowing head 310 to further expand the opening of the packaging bag, thereby solving the technical problems in the prior art that the bag opening mechanism has a complex structure, the opening of the packaging bag is narrow, the product is difficult to enter after winding, and the mechanism is difficult to detach from the opening of the packaging bag after the bag is opened, thereby meeting the technical requirements of infusion set packaging.

[0035] Specifically, the mounting bracket 112 is in the shape of an elongated strip as a whole, and can be made of metal material. Two mounting brackets 112 are arranged in the vertical direction. The first driving member 111 can be set as an air claw cylinder or a stepping motor. The first driving member 111 can drive the mounting brackets 112 to move closer to or farther from each other. In this embodiment, four bag-supporting auxiliary blocks are provided, and two bag-supporting auxiliary blocks 120 are fixed to each other at both ends of each mounting bracket 112 by bolts. The mounting bracket 112 and the bag-supporting auxiliary block 120 are sent into the opening of the packaging bag by the telescopic assembly 200, and the two mounting brackets 112 are driven away from each other by the first driving member 111, so that the opening of the packaging bag is initially opened. The air blowing head 310 is fixed to the two ends of the mounting bracket 112 by bolts and other connecting members, and faces the packaging bag. In this way, the air blowing head 310 can blow air into the opening of the packaging bag to further expand the opening of the packaging bag.

[0036] Preferably, one end of the bag supporting auxiliary block 120 is fixed to one side of the mounting bracket 112 , and the other end of the bag supporting auxiliary block 120 extends in a direction perpendicular to the mounting bracket 112 .

[0037] Specifically, the bag-supporting auxiliary block 120 is in an "L" shape as a whole, and can be formed by bending a metal plate. The bag-supporting auxiliary block 120 has two parts at an angle, one of which is in a rectangular shape and the other in a triangular shape, and the two parts are arranged perpendicular to each other. The rectangular part is fixed to the mounting bracket 112 by bolts, and the triangular part is arranged toward the packaging bag to facilitate insertion into the packaging bag.

[0038] Furthermore, the bag-supporting device further includes a screw rod 113 , which is arranged along the moving direction of the mounting bracket 112 , and the mounting bracket 112 is movably arranged on the screw rod 113 .

Therefore, the flow rate of the gas blown out of the air blowing head 310 can be adjusted by adjusting the flow valve, thereby achieving the adjustment of the air blowing amount of the air blowing head 310.

[0046] Furthermore, the telescopic assembly 200 includes a second driving member 210 and a support block 220. The second driving member 210 is arranged on the support block 220. The support block 220 is used to connect to the external platform. The driving end of the second driving member 210 is connected to the expansion mechanism 100. The second driving member 210 is arranged along the extension direction of the bag-supporting auxiliary block 120 to drive the bag-supporting auxiliary block 120 to move in the extension direction of one end of the bag-supporting auxiliary block 120.
