Description

Technical Field

[0001] The utility model relates to the technical field of food and drug packaging equipment, in particular to a continuous blow-filling-sealing device. Background Art

[0002] Single-mode (as shown in Figure 1 ) / multi-mode (as shown in Figure 2 ) continuous blow-filling-sealing integrated machine equipment enables the molten plastic pipe blank to complete continuous forming, filling and sealing without cutting, and all these processes are completed at one time under aseptic conditions. For the existing continuous blow-filling-sealing equipment, when forming different types of bottle shapes on the same equipment, with different center distances between bottle shapes and a large difference in filling capacity that requires ensuring filling accuracy, a complete set of filling systems needs to be configured separately for each specification, resulting in high production costs, long replacement time, and reduced production efficiency. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a continuous blow-filling-sealing device that can adapt to the filling of bottles with the same specification but different layouts and bottles with different specifications without replacing the entire set of filling components, has strong adaptability, high filling efficiency, and low cost.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

[0005] A continuous blow-filling-sealing device includes a filling component and a mold. The filling component includes a mounting seat, a liquid distribution block, a valve seat, and a filling needle connected in sequence. The liquid distribution block is provided with multiple liquid distribution channels. The liquid distribution block is detachably connected to the mounting seat and the valve seat, and the filling needle is detachably connected to the valve seat. A filling channel for communicating the liquid distribution channel and the filling needle is provided in the valve seat, and a blocking component is detachably provided at the top of the filling channel.

[0006] As a further improvement of the above technical solution:

[0007] A cooling and flow splitting plate is provided between the liquid distribution block and the valve seat. The liquid distribution block and the valve seat are both detachably connected to the cooling and flow splitting plate, and the filling channel extends to the top of the cooling and flow splitting plate.

[0008] The bottom of the filling needle is detachably connected with a filling needle head.

[0009] Multiple filling channels and multiple liquid distribution channels are provided. Multiple filling needles are provided. The multiple filling channels are evenly arranged along the length direction of the valve seat. The multiple liquid distribution channels and the multiple filling needles are in one-to-one correspondence and communication with the multiple filling channels.

[0010] A plurality of the filling channels and the liquid distribution channels are provided, a plurality of filling needles are provided, the plurality of filling channels are uniformly arranged along the length direction of the valve seat, the number of the liquid distribution channels is less than that of the filling channels, the plurality of liquid distribution channels are respectively and correspondingly communicated with the filling channels, and the plurality of filling needles are in one-to-one correspondence and communication with the plurality of filling channels.

[0011] The plurality of liquid distribution channels are all divided into multiple groups of channel groups, and the multiple groups of channel groups are arranged at intervals along the length direction of the liquid distribution block.

[0012] A plurality of the filling channels and the liquid distribution channels are provided, a plurality of filling needles are provided, the plurality of filling channels are uniformly arranged along the length direction of the valve seat, the number of the liquid distribution channels is the same as that of the filling needles and is less than that of the filling channels, and the plurality of liquid distribution channels and the plurality of filling needles are respectively and correspondingly communicated with both ends of the filling channels.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] In the continuous blow-filling-sealing device disclosed by the present utility model, the filling liquid sequentially passes through the liquid distribution channel, the filling channel and the filling needle to fill the bottle body. Since the liquid distribution block is detachably connected to both the mounting seat and the valve seat, by replacing the liquid distribution block, the number and diameter of the liquid distribution channels can be changed, so as to adapt to the problem of whether the bottle body needs to be formed in a row. At the same time, if a blocking component is used to block the filling channel, the blocked filling channel is not connected to the corresponding filling needle, which can adapt to the filling of large-sized bottle bodies. Without replacing the whole set of filling components, it can adapt to the filling of bottle bodies with the same specification but different layouts and bottle bodies with different specifications, with strong adaptability, high filling efficiency and low cost.

[0027] Embodiment 1

[0028] Figures 3 to 7An embodiment of the continuous blow - fill - seal device of the present utility model is shown, which includes a filling assembly 1 and a mold 2. The filling assembly 1 includes a mounting base 3, a liquid - distributing block 4, a valve seat 5, and a filling needle 6 connected in sequence. The liquid - distributing block 4 is provided with a plurality of liquid - distributing channels 41. The liquid - distributing block 4 is detachably connected to both the mounting base 3 and the valve seat 5, and the filling needle 6 is detachably connected to the valve seat 5. A filling channel 51 for connecting the liquid - distributing channel 41 and the filling needle 6 is provided in the valve seat 5, and a blocking component is detachably provided at the top of the filling channel 51.

[0029] For this continuous blow - fill - seal device, the filling liquid passes through the liquid - distributing channel 41, the filling channel 51, and the filling needle 6 in sequence to fill the bottle body. Since the liquid - distributing block 4 is detachably connected to both the mounting base 3 and the valve seat 5, by replacing the liquid - distributing block 4, the number and spacing of the liquid - distributing channels 41 can be changed, so as to adapt to the problem of whether the bottle body needs to be formed in a row. At the same time, if the filling channel 51 is blocked by a blocking component and the blocked filling channel 51 is not connected to the corresponding filling needle 6, it can adapt to the filling of large - sized bottle bodies. Without replacing the entire filling assembly 1, it can adapt to the filling of bottle bodies with the same specification but different layouts and bottle bodies with different specifications, with strong adaptability, high filling efficiency, and low cost.

[0030] Further preferably, as Figures 3 to 6 shown, in this embodiment, there are multiple filling channels 51 and multiple liquid - distributing channels 41, and multiple filling needles 6 are provided. The multiple filling channels 51 are evenly arranged along the length direction of the valve seat 5, and the multiple liquid - distributing channels 41 and the multiple filling needles 6 are in one - to - one correspondence and communication with the multiple filling channels 51. Multiple bottle bodies can be filled simultaneously, and the filling efficiency is high.

[0031] Further preferably, as Figures 3 to 6 shown, in this embodiment, a cooling and flow - splitting plate 7 is provided between the liquid - distributing block 4 and the valve seat 5. Both the liquid - distributing block 4 and the valve seat 5 are detachably connected to the cooling and flow - splitting plate 7, and the filling channel 51 extends to the top of the cooling and flow - splitting plate 7. The cooling effect is improved, and at the same time, it is convenient for the disassembly and replacement of the liquid - distributing block 4.

[0032] Specifically, as Figure 3 shown, the liquid - distributing channel 41, the filling channel 51, and the filling needle 6 are in one - to - one correspondence and communication for filling, and the bottle row without intervals is filled and formed.

[0033] Embodiment Two

[0034] The continuous blow - fill - seal device of this embodiment is substantially the same as that of Embodiment One, except that: the continuous blow - fill - seal device of this embodiment, as Figure 4As shown, there are multiple filling channels 51 and multiple liquid distribution channels 41. There are multiple filling needles 6. The multiple filling channels 51 are evenly arranged along the length direction of the valve seat 5. The number of liquid distribution channels 41 is less than that of the filling channels 51. The multiple liquid distribution channels 41 are respectively and correspondingly communicated with the filling channels 51. The multiple filling needles 6 are correspondingly communicated with the multiple filling channels 51 one by one. By replacing the liquid distribution block 4 and regularly reducing the number of liquid distribution channels 41, the corresponding bottles will not be filled. Finally, the unfilled bottles can be cut off as waste. Only by replacing the liquid distribution block 4, it is possible to achieve the filling of bottles with different layouts without replacing the entire filling assembly 1. Moreover, the liquid distribution channels 41 corresponding to the unfilled bottles are cancelled, which can prevent the residue of the liquid medicine.

[0035] Further preferably, in this embodiment, the multiple liquid distribution channels 41 are all divided into multiple groups of flow channels 42, and the multiple groups of flow channels 42 are arranged at intervals along the length direction of the liquid distribution block 4.

[0036] Embodiment Three

[0037] The continuous blow-filling-sealing device of this embodiment is substantially the same as that of Embodiment Two, except that: the continuous blow-filling-sealing device of this embodiment, as Figure 5 shown, there are multiple filling channels 51 and multiple liquid distribution channels 41. There are multiple filling needles 6. The multiple filling channels 51 are evenly arranged along the length direction of the valve seat 5. The number of liquid distribution channels 41 is the same as that of the filling needles 6, and both are less than that of the filling channels 51. The multiple liquid distribution channels 41 and the multiple filling needles 6 are respectively and correspondingly communicated with both ends of the filling channels 51 corresponding to them. By replacing the liquid distribution block 4 and further reducing the number of liquid distribution channels 41, the corresponding bottles will also not be filled. At the same time, the blocking component blocks the filling channels 51 that are not filled to prevent water leakage. Since the specification of the filled bottles becomes larger, it is necessary to remove the filling needles 6 that are not filled to avoid interference during mold closing, and then it is possible to fill bottles with a larger specification.

[0038] Embodiment Four

[0039] The continuous blow-filling-sealing device of this embodiment is substantially the same as that of Embodiment Three, except that: the continuous blow-filling-sealing device of this embodiment, as Figure 6 shown, if within a reasonable production cycle that meets the product production capacity, the bottle filling volume, that is, the milliliter capacity, does not differ much, it can be achieved by adjusting the filling time or filling pressure. The liquid distribution channels 41 and the filling channels 51 do not need to be changed. It is preferred to consider fine-tuning the filling time and pressure to achieve this.

[0040] Embodiment Five

[0041] The continuous blow-filling-sealing device of this embodiment is substantially the same as that of Embodiment Four, except that: the continuous blow-filling-sealing device of this embodiment, as Figure 7As shown, the bottom of the filling needle 6 is detachably connected with a filling needle head 61. If the filling volume of the bottle body, that is, the milliliter capacity, varies too much, and adjusting the filling time and pressure cannot meet the production cycle, then by replacing the liquid distribution block 4, the valve seat 5 and the filling needle head 61, the diameters of the liquid distribution channel 41, the filling channel 51 and the filling needle head 61 are changed to adapt to the filling of different bottle body bottle mouths with inconsistent sizes.

[0042] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the above-disclosed technical content without departing from the scope of the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
