The number of the first hydraulic cylinder 42 and the second hydraulic cylinder 43 is two respectively, and the two first hydraulic cylinders 42 and the two second hydraulic cylinders 43 are distributed on the side wall of the fixed frame 41 from top to bottom. The output end of the first hydraulic cylinder 42 passes through the fixed frame 41 and is fixedly connected to an upper mold frame 44, and the output end of the second hydraulic cylinder 43 passes through the fixed frame 41 and is fixedly connected to a lower mold frame 45. The side wall of the upper mold frame 44 is fixedly equipped with an upper molding die 46, and the side wall of the lower mold frame 45 is fixedly equipped with a lower molding die 47. Heating units are respectively arranged in the upper molding die 46 and the lower molding die 47. The heating units are used to increase the temperature of the upper molding die 46 and the lower molding die 47, so that the upper molding die 46 and the lower molding die 47 can heat and mold the film material passing through the middle.

[0020] The side wall of the upper mold frame 44 is fixedly equipped with a third hydraulic cylinder 48, and the output end of the second hydraulic cylinder 48 passes through the upper mold frame 44 and is fixedly connected to a sealing mold 49. A heating unit is also provided in the sealing mold 49. The regional thermoplastic molding of the infusion bag is completed through the upper molding mold 46 and the lower molding mold 47. The sealing mold 49 is used to seal the infusion bag after filling. The regional filling and sealing method is adopted to improve the filling and processing efficiency of the infusion bag.

[0021] The surfaces of the two fixed plates 3 are respectively fixedly equipped with guide components 5. The guide components 5 are arranged to increase the accuracy of the moving stroke of the upper mold frame 44 and the lower mold frame 45, so as to facilitate the docking of the upper mold frame 44 and the lower mold frame 45 on both sides, and improve the accuracy and precision of the docking position of the upper mold frame 44 and the lower mold frame 45 on both sides, thereby achieving the purpose of improving the quality of the infusion bag production products.

[0022] like Figure 2 and Figure 3As shown in the figure, the guide assembly 5 includes a guide frame 51, which is symmetrically fixed on the two ends of the fixed plate 3 in the left and right directions, and a guide shaft 52 is fixedly installed between the two guide frames 51. The number of the guide shafts 52 is at least three, two of which pass through the upper mold frame 44 and are slidably connected to the upper mold frame 44, and two of which pass through the lower mold frame 45 and are slidably connected to the lower mold frame 45.

[0023] like Figure 1 and Figure 2 As shown in the figure, a perfusion mechanism 6 is fixedly installed on the top of the two fixed plates 3, and the liquid medicine is filled into the infusion bag through the provided filling mechanism 6. The perfusion mechanism 6 includes a support frame 61, and the support frame 61 is fixedly installed on the surface of the two fixed plates 3.

The filling tube 64 is connected to the external liquid supply tube and air supply tube through a three-way tube. The processing and filling operation of the infusion bag is completed by switching the liquid supply and air supply.

[0025] Working principle: During the use of the device, the multi-layer co-extruded film is first sleeved on the outside of the filling tube 64, and then the multi-layer co-extruded film is passed between the molding mechanisms 4 on both sides. When processing and filling the infusion bag, the output end of the second hydraulic cylinder 43 is first controlled to move, driving the lower mold frame 45 and the lower molding die 47 to move, completing the bottom packaging of the infusion bag, and then the gas is introduced into the lower molding die 47 through the filling tube 64, and then the output end of the first hydraulic cylinder 42 is controlled again to move, so that the upper mold frame 44 drives the upper molding die 47 to move. The tool 46 moves, and with the continuous introduction of gas from the filling tube 64, the bag body of the infusion bag is formed in the upper molding die 46 and the lower molding die 47, and then the filling tube 64 fills the medicine into the formed bag body. After the medicine is quantitatively distributed into the bag body of each infusion bag, the fourth hydraulic cylinder 62 is controlled to drive the lifting frame 63 to move upward to move the filling tube 64 upward. Finally, the output end of the third hydraulic cylinder 48 is controlled to move to drive the sealing mold 49 to seal the infusion bag after the filling is completed, and the sealed infusion bag is subsequently transported through the conveying mechanism 2.
