[0029] The utility model will be further explained in detail in conjunction with the drawings and specific embodiments of the specification.

[0030] As Figure 2 And Figure 6 The blow-filling-sealing integrated machine of the embodiment, as shown in the drawings, includes a partition 3 for separating the clean area 1 from the unclean area 2, the clean area 1 is provided with a horizontally movable tube embryo extrusion assembly 4, a filling mechanism 5 arranged in the tube embryo extrusion assembly 4, and a forming device 6 arranged below the tube embryo extrusion assembly 4, and a first operation area 11 is arranged in the clean area 1, and the first operation area 11 is located between the forming device 6 and the partition 3. The partition 3 can be a partition wall or a partition plate.

[0031] As shown in the drawings, Figure 2 And Figure 4 The blow-filling-sealing integrated machine of the embodiment, the forming device 6 is no longer in close contact with the partition 3, but a first operation area 11 is arranged between the forming device 6 and the partition 3, when the tube embryo extrusion assembly 4 is located above the forming device 6, production can be carried out, that is, the closed sterile production process of one-step forming, extruding, filling, sealing and demolding is completed. When the tube embryo extrusion assembly 4 and the filling mechanism 5 need to be maintained, the tube embryo extrusion assembly 4 is moved from above the forming device 6 to above the first operation area 11 (the filling mechanism 5 is arranged in the tube embryo extrusion assembly 4, so it can move with the tube embryo extrusion assembly 4), at this time, the first operation area 11 can be used as an operation space for maintenance, and the tube embryo extrusion assembly 4 and the filling mechanism 5 do not need to be moved to the unclean area 2, which avoids the risk of being polluted by the environment of the unclean area 2, and the structure is simple and reasonable.

[0032] Further, in the embodiment, the blow-filling-sealing all-in-one machine further comprises an extrusion screw assembly 8 arranged in the partition 3 and a translation driving mechanism 7 for driving the extrusion screw assembly 8 to move reciprocatingly along the axial direction, the translation driving mechanism 7 is connected with the extrusion screw assembly 8 at one end of the non-clean area 2, the tube blank extrusion assembly 4 is connected with the extrusion screw assembly 8 at one end of the clean area 1, and the extrusion screw assembly 8 is provided with a isolation cover 81, and the two ends of the isolation cover 81 are sealingly connected with the extrusion screw assembly 8. The translation driving mechanism 7 can drive the extrusion screw assembly 8 to move reciprocatingly along the axial direction. Since the discharge end of the extrusion screw assembly 8 is connected with the tube blank extrusion assembly 4, the tube blank extrusion assembly 4 and the filling mechanism 5 can be driven by the extrusion screw assembly 8 to move horizontally. For details, see Figure 2 and Figure 4 When the part of the extrusion screw assembly 8 located in the clean area 1 moves to the non-clean area 2, the isolation cover 81 moves along with it, which can provide protection for the extrusion screw assembly 8 and avoid pollution from the non-clean area 2. When production needs to be performed again, the isolation cover 81 can be sterilized, and preferably, the isolation cover 81 can adopt a regular structure such as a circular or square shape. Compared with directly sterilizing the extrusion screw assembly 8 with a complex shape, the difficulty is reduced and the workload is reduced.

[0033] For details, see Figure 6 In the embodiment, a gap is provided between the isolation cover 81 and the partition 3, and the air pressure in the clean area 1 is higher than that in the non-clean area 2. The gap is provided between the isolation cover 81 and the partition 3 so that the isolation cover 81 can move smoothly and avoid interference. The air pressure in the clean area 1 is higher than that in the non-clean area 2, which can prevent the gas in the non-clean area 2 from flowing to the clean area 1 through the gap between the isolation cover 81 and the partition 3, thereby avoiding pollution of the clean area 1. The structure is simple and effective.

[0034] Preferably, the gap between the isolation cover 81 and the partition 3 is 0.1-3.5 mm, which facilitates smooth movement of the isolation cover 81 and does not affect the pressure difference between the clean area 1 and the non-clean area 2. Further preferably, the gap between the isolation cover 81 and the partition 3 is 0.5-2 mm.

[0035] Further, a laminar flow cover (not shown in the figure) can be provided on the outer periphery of the isolation cover 81, so that the isolation cover 81 is always in a laminar flow environment and does not need to be artificially sterilized when moving from the non-clean area 2 to the clean area 1 again;

[0036] Alternatively, a bellows (not shown in the figure) is connected between the isolation cover 81 and the partition 3. The bellows can realize isolation between the non-clean area 2 and the clean area 1, and can be stretched and contracted, which does not affect the reciprocating movement of the extrusion screw assembly 8 along the axial direction, and the structure is simple and reliable.

[0037] Preferably, the dimension of the first operating area 11 along the axial direction of the extrusion screw assembly 8 is L, 0.5m≤L≤2.5m, which can accommodate the preform extrusion assembly 4 and the filling mechanism 5 for maintenance, while making full use of the space in the clean area 1. More preferably, 1m≤L≤1.5m.

[0038] Furthermore, in this embodiment, a support member 9 for supporting the extrusion screw assembly 8 is connected between the molding device 6 and the separator 3, and the support member 9 is located above the first operating area 11. Since the extrusion screw assembly 8 is relatively long and needs to drive the preform extrusion assembly 4 to move back and forth, setting the support member 9 to provide support for the extrusion screw assembly 8 is beneficial to improving the structural strength and preventing the extrusion screw assembly 8 from deforming under stress.

[0039] Furthermore, in this embodiment, a first operating platform 12 is provided below the first operating area 11, and a second operating platform 61 is provided above the molding device 6. Both the first operating platform 12 and the second operating platform 61 are equipped with stairs 13. Operators can use the stairs 13 to reach the first operating platform 12 to maintain and repair the preform extrusion assembly 4 and the filling mechanism 5, which have been moved to the top of the first operating area 11. Alternatively, operators can use the stairs 13 to reach the second operating platform 61, which can serve as a filling and maintenance platform (when the preform extrusion assembly 4 and the filling mechanism 5 are in production and have not been moved to the top of the first operating area 11).

[0040] Participate specifically Figure 3 and Figure 5 In this embodiment, the translation drive mechanism 7 includes a guide rail 71, a rack 72 arranged parallel to the guide rail 71, a slide 73 mounted on the guide rail 71, and a drive gear 74 meshing with the rack 72. The guide rail 71 is arranged parallel to the extrusion screw assembly 8, and the drive gear 74 is mounted on the slide 73. One end of the extrusion screw assembly 8 located in the non-clean area 2 is mounted on the slide 73. During operation, the drive gear 74 rotates and rolls along the rack 72, thereby driving the slide 73, the extrusion screw assembly 8, etc., to move along the guide rail 71. The drive gear 74 and the rack 72 cooperate, ensuring reliable transmission and preventing slippage. The guide rail 71 provides guidance for the slide 73, making the movement smooth and stable. The preform extrusion assembly 4 and the filling mechanism 5 move with the extrusion screw assembly 8, resulting in a simple and reliable structure.

[0041] In a preferred embodiment, the guide rail 71 has two rows, the rack 72 has two racks located inside the two rows of guide rail 71, and the drive gear 74 has two gears arranged in a one-to-one correspondence with the two racks 72. The structure has good symmetry, which is conducive to the smooth movement of the slide 73, the tube preform extrusion assembly 4, the filling mechanism 5 and the extrusion screw assembly 8 as a whole.
