Description

Technical Field

[0001] This utility model relates to food and pharmaceutical packaging equipment, and more particularly to a filling device and a blow-fill-seal integrated machine. Background Technology

[0002] Currently, when disassembling the filling needle in a continuous blow-fill-seal machine, the entire preform extrusion assembly and filling mechanism are moved backward as a whole. The mold used to form the container is then offset from the preform extrusion assembly, allowing the filling needle to be removed from below the preform extrusion assembly. This solution is complex and cumbersome, and inconvenient to operate. Especially for black and white zone structures (different areas have different cleanliness levels, with the filling area having the highest cleanliness level), moving the preform extrusion assembly can disrupt the black and white zones, exposing the filling needle components to non-clean areas and posing a risk of contamination. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a filling device for a blow-fill-seal integrated machine that is simple in structure, easy to use, and helps to reduce the difficulty of disassembling the filling needle.

An operating platform is provided above the forming mold, and the filling needle assembly is connected to the liquid infusion assembly through a pipe. The filling needle assembly passes through the tube preform extrusion assembly.

[0007] As a further improvement to the above technical solution: the upper end of the injection needle assembly passes through the mounting base and the outer wall is provided with a limiting groove. The mounting base is provided with a push-pull insert plate, and one end of the insert plate is provided with a U-shaped slot that cooperates with the limiting groove.

[0008] As a further improvement to the above technical solution: the upper end of the injection needle assembly is provided with a first pipe interface, and the mounting base is provided with a detachable pressure plate.

[0009] As a further improvement to the above technical solution: the first pipe interface is provided with a limiting flange, which abuts against the lower surface of the pressure plate.

[0010] As a further improvement to the above technical solution: the upper end of the irrigation needle assembly is inserted into the lower end of the first pipeline interface, the upper end of the first pipeline interface is inserted into one end of the pipeline, and the infusion assembly is provided with a second pipeline interface, which is inserted into the pipeline.

The lifting drive mechanism and the infusion assembly are arranged opposite to each other on both sides of the filling needle assembly. The lifting drive mechanism is connected to the mounting base. The pipe is a flexible tube.

[0016] As a further improvement to the above technical solution:

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

[0036] Example 1

[0037] Figures 1 to 8This illustration shows an embodiment of the filling device of the blow-fill-seal integrated machine of this utility model. The filling device of this embodiment includes a tube preform extrusion assembly 2, a forming mold 8 located below the tube preform extrusion assembly 2, a mounting base 4 located above the tube preform extrusion assembly 2, a filling needle assembly 5 located on the mounting base 4, and a liquid infusion assembly 6 located on the side of the filling needle assembly 5 for controlling the filling flow. An operating platform 9 is provided above the forming mold 8. The filling needle assembly 5 is connected to the liquid infusion assembly 6 via a pipe 7 and is inserted into the tube preform extrusion assembly 2. The liquid infusion assembly 6 can be, for example, a filling valve assembly and / or a liquid infusion pump.

[0038] In this embodiment, the filling device of the blow-fill-seal integrated machine has an infusion component 6 for controlling the filling process. This component is located on the side of the filling needle assembly 5, without occupying the space above the filling needle assembly 5. The infusion component 6 is connected to the filling needle assembly 5 via a pipe 7. When the infusion component 6 is turned on, the liquid medicine can enter the filling needle assembly 5 (specifically, the filling needle 53) sequentially through the infusion component 6 and the pipe 7 for filling. An operating platform 9 is provided above the molding die 8. When the filling needle assembly 5 needs to be disassembled for maintenance, it can be pulled upwards using the operating platform 9 without moving the entire preform extrusion assembly 2, mounting base 4, and filling assembly 5. This makes the operation more convenient and greatly reduces the difficulty of disassembling the filling needle assembly 5. The disassembly of the filling needle assembly 5 can be completed in the filling area, avoiding the need to move the preform extrusion assembly 2 and the filling needle assembly 5 to non-clean areas, which would pose a risk of contamination. It also avoids the need to move the preform extrusion assembly 2 and the filling needle assembly 5 to another clean area for operation, which would result in higher equipment manufacturing costs (requiring the installation of corresponding guide rails and drive components, etc.). Preferably, a movable staircase is provided on one side of the operating platform 9. When it is necessary to disassemble the filling needle assembly 5, the operator can enter the operating platform 9 through the staircase. When production is required, the staircase can be moved to another area to avoid affecting the production process. Alternatively, an inspection window or inspection door can be provided on the laminar flow hood of the support 1. The operator can stand on the corridor parallel to the extrusion mechanism, reach into the operating platform 9 through the inspection window, and disassemble or assemble the filling needle assembly 5 in the filling area while standing outside the filling area. Or, the operator can enter the operating platform 9 through the inspection door to disassemble or assemble the filling assembly 5.

[0039] See details Figures 5 to 7In this embodiment, the upper end of the injection needle assembly 5 passes through the mounting base 4 and the outer wall is provided with a limiting groove 51. The mounting base 4 is provided with a push-pull insert plate 41, and one end of the insert plate 41 is provided with a U-shaped slot 411 that cooperates with the limiting groove 51. When the insert plate 41 is pushed into the mounting base 4, the U-shaped slot 411 can cooperate with the limiting groove 51 to restrict the up and down movement of the injection needle assembly 5. When it is necessary to pull the injection needle assembly 5 out of the mounting base 4 (of course, in other embodiments, the injection needle assembly 5 and the mounting base 4 can also be taken out upward as a whole), first pull out the insert plate 41 from the mounting base 4 to release the locking between the injection needles 5. The structure is simple, reliable and 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 pipe interface 52, and the mounting base 4 is provided with a detachable pressure plate 42 (for example, the pressure plate 42 is detachably connected to the mounting base 4 by screws, bolts, etc.). The upper end of the first pipe interface 52 passes through the pressure plate 42 and is detachably connected to the pipe 7. When it is necessary to pull the injection needle assembly 5 out of the mounting base 4, after pulling out the insert plate 41, it is also necessary to remove the pressure plate 42 and disconnect the connection between the injection needle assembly 5 and the pipe 7. Finally, the injection needle assembly 5 can be taken out upwards. The injection needle assembly 5 includes multiple injection needles 53, and the multiple injection needles 53 are all pressed onto the mounting base 4 by the same pressure plate 42 (i.e., sharing the pressure plate 42), which can reduce the number of pressure plates 42, save costs, and improve disassembly efficiency. The insert 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, the first pipe interface 52 is provided with a limiting flange 521, which abuts against the lower surface of the pressure plate 42 and can play a limiting role to prevent the first pipe interface 52 from moving up and down in the mounting base 4.

[0042] In a preferred embodiment, the upper end of the infusion needle assembly 5 is inserted into the lower end of the first conduit interface 52, the upper end of the first conduit interface 52 is inserted into one end of the conduit 7, and the infusion assembly 6 is provided with a second conduit interface 61 (specifically as follows). Figure 4 As shown in the diagram, the second pipe interface 61 is plugged into the pipe 7. The components along the liquid flow path are connected by plug-in joints, making installation and disassembly convenient and time-saving.

[0043] Furthermore, in this embodiment, the upper end of the filling needle assembly 5 is provided with a positioning groove 56. The operating tool can use the positioning groove 56 to fix the filling needle assembly 5 so that the filling needle assembly 5 can be taken out upwards, which is simple and effective. Preferably, the positioning groove 56 is an annular groove surrounding the outer periphery of the filling assembly 5, which makes positioning more convenient.

[0044] See details Figure 8In this embodiment, the filling needle assembly 5 includes a filling needle 53, a first cooling jacket 54 disposed on the outer periphery of the filling needle 53, and a second cooling jacket 55 disposed on the outer periphery of the first cooling jacket 54. The mounting base 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 that communicates with the second cooling jacket 55.

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

[0046] When the equipment is working, the preform extrusion assembly 2 extrudes molten plastic preforms at a relatively high temperature. The filling needle 53 needs to penetrate the preform extrusion assembly 2 and extend into the formed container for filling. The high temperature may affect the medication inside the filling needle 53, especially for temperature-sensitive medications. Therefore, a cooling medium (such as cooling water) can enter the first cooling jacket 54 through the cooling medium inlet 43, flowing downwards under gravity. After reaching the lower end of the first cooling jacket 54, it enters the second cooling jacket 55 through the connecting hole 541, then changes direction and flows upwards, finally exiting from the cooling medium outlet 44. This effectively absorbs the heat around the filling needle 53, forming a low-temperature barrier around the filling needle 53, preventing heat transfer to the medication inside the filling needle 53. This structure is both reasonable and effective.

[0047] Example 2

[0048] Figures 1 to 8 This illustration shows an embodiment of the blow-fill-seal integrated machine of the present invention. The machine includes a support 1, a lifting drive mechanism 3, and the aforementioned filling device. The tube preform extrusion assembly 2, the lifting drive mechanism 3, and the infusion assembly 6 are all mounted on the support 1. The lifting drive mechanism 3 and the infusion assembly 6 are arranged opposite each other on both sides of the filling needle assembly 5. The lifting drive mechanism 3 is connected to the mounting base 4, and the pipe 7 is a flexible hose. For continuous single-mold blow-fill-seal integrated machine equipment, during normal production, the lifting drive mechanism 3 drives the mounting base 4 and the filling needle assembly 5 to lift and lower to complete the filling. Since the pipe 7 is a flexible hose, it does not obstruct the lifting and lowering movement of the filling needle assembly 5. The lifting drive mechanism 3 and the infusion assembly 6 are arranged opposite each other on both sides of the filling needle assembly 5, and do not occupy the space above the filling needle assembly 5. For continuous multi-mold blow-fill-seal integrated machines, during normal production, the filling needle assembly 5 is in a fixed position, and the pipe 7 can be a rigid pipe. However, before and after formal production, the filling needle assembly 5 needs to be raised and lowered to prevent the unstable output tube blanks from sticking to the filling needle assembly 5. Therefore, for continuous multi-mold blow-fill-seal integrated machines, a flexible hose connection for the pipe 7 is more suitable. Specifically... Figure 3As shown, when maintenance is required on the filling needle assembly 5, the lifting drive mechanism 3 drives the mounting base 4 and the filling needle assembly 5 to a low position, thereby reducing the height at which the filling needle assembly 5 can be taken out, which also reduces the difficulty of disassembly to a certain extent. Then, the aforementioned insert 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 upwards.

[0049] Furthermore, in this embodiment, the lifting drive mechanism 3 includes a lifting drive component 31 (e.g., a cylinder, hydraulic cylinder, or lead screw and nut pair), a lifting guide rail 32, and a lifting slider 33 disposed on the lifting guide rail 32. The lifting drive component 31 and the lifting guide rail 32 are disposed on the bracket 1, the lifting slider 33 is connected to the lifting drive component 31, and the mounting base 4 is disposed on the lifting slider 33.

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

[0051] A continuous multi-mold BFS (continuous blow-fill-seal) is an aseptic filling machine that uses multiple molds that rotate continuously around a preform to form a container, fill the preform, and then seal it using the next mold. Its structure, from bottom to top, typically consists of a mold chain, a preform extrusion assembly, and a filling mechanism. The filling needle passes through the preform extrusion assembly from top to bottom to reach the forming mold, and remains stationary during filling. In contrast, a single-mold BFS, after the forming mold closes to form the bottle, requires the filling needle to descend into the bottle for filling, and then rises again to allow the sealing mold to close and seal the bottle.

[0052] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
