[0035] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Embodiment 1

[0037] Figures 1 to 8An embodiment of the filling device of the blow-fill-seal integrated machine of the present invention is shown. The filling device of the blow-fill-seal integrated machine of this embodiment comprises a tube embryo extrusion assembly 2, a forming die 8 disposed below the tube embryo extrusion assembly 2, a mounting seat 4 disposed above the tube embryo extrusion assembly 2, a filling needle assembly 5 disposed on the mounting seat 4, and an infusion assembly 6 disposed on the side of the filling needle assembly 5 for controlling the filling on and off, an operating platform 9 is disposed above the forming die 8, the filling needle assembly 5 is connected to the infusion assembly 6 through a pipeline 7, and the filling needle assembly 5 is inserted into the tube embryo extrusion assembly 2. Among them, the infusion assembly 6 can be, for example, a filling valve group and / or an infusion pump.

[0038] In the filling device of the blow-fill-seal integrated machine of this embodiment, the infusion component 6 for controlling the filling on and off is arranged on the side of the needle filling component 5, does not occupy the space above the needle filling component 5, and the infusion component 6 is connected to the needle filling component 5 through the pipeline 7. When the infusion component 6 is turned on, the liquid medicine can enter the needle filling component 5 (specifically the needle filling 53) through the infusion component 6 and the pipeline 7 in sequence for filling. An operating platform 9 is arranged above the molding die 8. When the needle filling component 5 needs to be disassembled and maintained, the needle filling component 5 can be pulled out upward with the help of the operating platform 9, without moving the entire tube embryo extrusion component 2, the mounting seat 4 and the filling component 5, etc., which is more convenient to operate and greatly reduces the difficulty of disassembling the needle filling component 5. The disassembly of the needle filling component 5 is completed in the filling area, avoiding moving the tube embryo extrusion component 2 and the needle filling component 5 to a non-clean area to cause a risk of contamination, and also avoiding moving the tube embryo extrusion component 2 and the needle filling component 5 to another clean area for operation, resulting in a higher equipment manufacturing cost (needing to set corresponding guide rails and driving components, etc.). Preferably, a movable staircase is provided on one side of the operating platform 9. When the filling needle assembly 5 needs to be disassembled, the operator enters the operating platform 9 through the staircase. When production is required, the staircase is moved to other areas to avoid affecting the production process. An inspection window or inspection door can also be provided on the laminar flow hood of the bracket 1. The operator stands on a corridor parallel to the extrusion mechanism and reaches into the operating platform 9 through the inspection window. The operator stands outside the filling area to disassemble and assemble the filling needle assembly 5 in the filling area, or enters the operating platform 9 through the inspection door to disassemble and assemble the filling assembly 5.

[0039] See Figures 5 to 7In this embodiment, the upper end of the injection needle assembly 5 is inserted into the mounting seat 4 and a limiting groove 51 is provided on the outer wall. The mounting seat 4 is provided with a push-pull plug plate 41, and one end of the plug plate 41 is provided with a U-shaped card groove 411 that cooperates with the limiting groove 51. When the plug plate 41 is pushed into the mounting seat 4, the U-shaped card groove 411 can be used to cooperate with the limiting groove 51 to limit the up and down movement of the injection needle assembly 5; when the injection needle assembly 5 needs to be pulled out from the mounting seat 4 (of course, in other embodiments, the injection needle assembly 5 and the mounting seat 4 can also be taken out upward as a whole), first pull out the plug plate 41 from the mounting seat 4 to release the lock between the injection needles 5, which has a simple and reliable structure and is easy to operate.

[0040] Furthermore, in this embodiment, the upper end of the injection needle assembly 5 (specifically the injection needle 53) is provided with a first pipeline interface 52, and the mounting seat 4 is provided with a detachable pressing plate 42 (for example, the pressing plate 42 and the mounting seat 4 are detachably connected by screws, bolts, etc.), and the upper end of the first pipeline interface 52 passes through the pressing plate 42 and is detachably connected to the pipeline 7. When the injection needle assembly 5 needs to be pulled out from the mounting seat 4, after pulling out the plug plate 41, it is also necessary to remove the pressing plate 42, and disconnect the connection between the injection needle assembly 5 and the pipeline 7, and finally the injection needle assembly 5 can be taken out upward. The injection needle assembly 5 includes a plurality of injection needles 53, and the plurality of injection needles 53 are all pressed on the mounting seat 4 by the same pressing plate 42 (i.e., the common pressing plate 42), which can reduce the number of pressing plates 42, save costs, and improve disassembly efficiency. The plug plate 41 can be set one-to-one with the injection needle 53, or one-to-many with the injection needle 53.

[0041] Furthermore, in this embodiment, a limiting flange 521 is provided on the first pipe interface 52 , and the limiting flange 521 abuts against the lower surface of the pressure plate 42 , which can play a limiting role and prevent the first pipe interface 52 from moving up and down in the mounting seat 4 .

[0042] As a preferred embodiment, the upper end of the injection needle assembly 5 is plugged into the lower end of the first pipeline interface 52, the upper end of the first pipeline interface 52 is plugged into one end of the pipeline 7, and the infusion assembly 6 is provided with a second pipeline interface 61 (specifically as shown in FIG. Figure 4 As shown in FIG. 1 , the second pipeline interface 61 is plugged into the pipeline 7. The components on the liquid medicine flow path are plugged into each other, which is convenient for installation and disassembly and saves time.

[0043] Furthermore, in this embodiment, a positioning groove 56 is provided at the upper end of the filling needle assembly 5. The operating tool can use the positioning groove 56 to fix the filling needle assembly 5 so as to remove the filling needle assembly 5 upward, which is simple and effective. Preferably, the positioning groove 56 is an annular groove around the outer circumference of the filling assembly 5, which is more convenient for positioning.

[0044] See Figure 8In this embodiment, the injection needle assembly 5 includes an injection needle 53, a first cooling jacket 54 arranged on the outer periphery of the injection needle 53, and a second cooling jacket 55 arranged on the outer periphery of the first cooling jacket 54. The mounting seat 4 is provided with a cooling medium inlet 43 and a cooling medium outlet 44. The lower end of the first cooling jacket 54 is provided with a connecting hole 541 connected with the second cooling jacket 55.

[0045] The cooling medium inlet 43 is communicated with the upper end of the first cooling jacket 54 , and the upper end of the second cooling jacket 55 is communicated with the cooling medium outlet 44 .

[0046] When the equipment is working, the tube embryo extrusion component 2 extrude the molten plastic tube embryo, the temperature is relatively high, and the filling needle 53 needs to penetrate the tube embryo extrusion component 2 and extend into the molded container for filling. The high temperature may have an impact on the liquid medicine in the filling needle 53, especially the temperature-sensitive liquid medicine. To this end, the cooling medium (such as cooling water) can enter the first cooling jacket 54 through the cooling medium inlet 43, flow downward under the action of gravity, and enter the second cooling jacket 55 through the connecting hole 541 after reaching the lower end of the first cooling jacket 54, and then change direction to flow upward, and finally flow out from the cooling medium outlet 44, which can fully absorb the heat around the filling needle 53, form a low-temperature barrier on the periphery of the filling needle 53, and block the heat from being transferred to the liquid medicine inside the filling needle 53. The structure is reasonable and effective.

[0047] Embodiment 2

[0048] Figures 1 to 8 An embodiment of the blow-fill-seal integrated machine of the present invention is shown. The blow-fill-seal integrated machine of this embodiment includes a bracket 1, a lifting drive mechanism 3 and the filling device of the blow-fill-seal integrated machine mentioned above. The tube blank extrusion component 2, the lifting drive mechanism 3 and the infusion component 6 are all arranged on the bracket 1. The lifting drive mechanism 3 and the infusion component 6 are arranged on both sides of the filling needle component 5 relative to each other. The lifting drive mechanism 3 is connected to the mounting seat 4, and the pipeline 7 is a hose. For the continuous single-mode blow-fill-seal integrated machine equipment, during normal production, the lifting drive mechanism 3 drives the mounting seat 4 and the filling needle component 5 to lift and lower to complete the filling. Since the pipeline 7 adopts a hose, it will not hinder the lifting movement of the filling needle component 5. The lifting drive mechanism 3 and the infusion component 6 are arranged on both sides of the filling needle component 5 relative to each other, and will not occupy the space above the filling needle component 5. For continuous multi-mode blow-fill-seal integrated equipment, during normal production, the needle filling assembly 5 is located in a fixed position, and the pipeline 7 can be a hard tube. However, before and after formal production, the needle filling assembly 5 needs to be raised and lowered to prevent unstable output tube blanks from sticking to the needle filling assembly 5. Therefore, for continuous multi-mode blow-fill-seal integrated equipment, it is more appropriate to use a hose to connect the pipeline 7. Figure 3As shown, when the filling needle assembly 5 needs to be maintained, the lifting drive mechanism 3 drives the mounting seat 4 and the filling needle assembly 5 to descend to a low position to reduce the height of the filling needle assembly 5 for being taken out upward, which also reduces the difficulty of disassembly to a certain extent. Then the above-mentioned plug plate 41 and pressure plate 42 are removed, the first pipe interface 52 is taken out, and finally the filling needle 53 can be taken out upward.

[0049] Furthermore, in this embodiment, the lifting drive mechanism 3 includes a lifting drive component 31 (such as a cylinder, an oil cylinder or a screw nut pair, etc.), a lifting guide rail 32 and a lifting slider 33 arranged on the lifting guide rail 32. The lifting drive component 31 and the lifting guide rail 32 are arranged on the bracket 1, the lifting slider 33 is connected to the lifting drive component 31, and the mounting seat 4 is arranged on the lifting slider 33.

[0050] The lifting drive 31 drives the lifting slider 33 to move up and down along the lifting guide rail 32. The lifting guide rail 32 provides a guide for the lifting slider 33, so that the up and down movement process is stable and smooth to avoid deviation. The mounting seat 4 rises and falls synchronously with the lifting slider 33, and the filling needle assembly 5 rises and falls synchronously with the mounting seat 4. The structure is simple and reliable. It should be noted that a tube embryo support gas channel and a filling sealing seat are also provided below the mounting seat 4. This part of the structure can be, for example, the relevant technical features disclosed in the patent application number 202323030796.9, which will not be repeated here.

[0051] Continuous multi-mode BFS (continuous blowing, filling and sealing machine) is an aseptic filling equipment that uses multiple molds that rotate continuously around the preform to form the container, fill the inside of the preform, and then seal it through the next mold. Its bottom-up structure is usually a mold chain, a tube preform extrusion assembly, and a filling mechanism. The filling needle needs to pass through the tube preform extrusion assembly from top to bottom to reach the position of the forming mold. During filling, the filling needle remains in the set position. For single-mode BFS, after the forming mold is closed to form the bottle body, the filling needle needs to descend and extend into the bottle body for filling. After filling is completed, it rises again so that the subsequent sealing mold can close the mold to seal the bottle body.

[0052] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention should fall within the scope of protection of the technical solution of the present invention.
