Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging equipment technology, and in particular to a blow-fill-seal integrated machine. Background Technology

[0002] As attached Figure 1 As shown, currently available multi-die continuous BFS (Browser-First-Fill) equipment requires the extrusion die and filling mechanism to be moved to the rear of the non-clean area to ensure sufficient space for maintenance. This method exposes the extrusion die and filling mechanism, located in the clean area, to contamination from the non-clean environment. Furthermore, the movement of the extrusion die and filling mechanism through the non-clean area creates a connection between the clean and non-clean zones, potentially contaminating the clean area. After resetting the equipment, aseptic sterilization is required before production can resume. This cumbersome process reduces production efficiency and increases costs. 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 blow-fill-seal integrated machine that helps to avoid contamination of the preform extrusion assembly and filling mechanism and facilitates the formation of a space for maintenance of the preform extrusion assembly and filling mechanism.

[0008] Alternatively, the direction of movement of the forming device and / or the preform extrusion assembly is perpendicular to the length direction of the extrusion screw assembly;

[0009] Alternatively, the direction of movement of the forming device and / or the preform extrusion assembly includes a first direction and a second direction, wherein the first direction is parallel to the length direction of the extrusion screw assembly and the second direction is perpendicular to the length direction of the extrusion screw assembly.

[0010] As a further improvement to the above technical solution: the clean area is provided with a translation drive mechanism, which is connected to the forming device to drive the forming device to reciprocate in the clean area.

[0011] As a further improvement to the above technical solution: the translation drive mechanism includes a guide rail, a rack arranged parallel to the guide rail, a slide on the guide rail, and a drive gear on the slide that meshes with the rack. The guide rail is arranged parallel or perpendicular to the extrusion screw assembly, and the forming device is located on the slide.

[0012] As a further improvement to the above technical solution, it also includes a movable seat assembly, one end of which is located in the clean area and the other end in the non-clean area. The preform extrusion assembly is located at the end of the movable seat assembly located in the clean area, and the extrusion screw assembly is located at the end of the movable seat assembly located in the non-clean area. The non-clean area is provided with a translation drive mechanism, which is connected to the movable seat assembly to drive the preform extrusion assembly and the filling mechanism to reciprocate in the clean area.

[0013] As a further improvement to the above technical solution: the translation drive mechanism includes a guide rail, a rack arranged parallel to the guide rail, and a drive gear meshing with the rack. The guide rail is arranged parallel to the extrusion screw assembly. The moving seat assembly is located at one end of the non-clean area and is disposed on the guide rail. The drive gear is disposed on the moving seat assembly.

[0014] As a further improvement to the above technical solution: the guide rail has two rows, the rack has two racks located inside the two rows of the guide rail, and the drive gear has two gears arranged in a one-to-one correspondence with the two racks.

[0015] As a further improvement to the above technical solution: the moving direction of the preform extrusion assembly and the filling mechanism is perpendicular to the length direction of the extrusion screw assembly, the separator is provided with a notch for the moving seat assembly and the extrusion screw assembly to move, and at least one side of the separator is provided with a sliding door for sealing the notch, and the moving seat assembly and the extrusion screw assembly pass through the sliding door.

One end of the third movable seat is located in the clean area, and the other end passes through the separator and is connected to the second movable seat.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] The blow-fill-seal integrated machine disclosed in this utility model allows the forming device and / or preform extrusion assembly to move between at least two different positions within a clean area. Taking the moving forming device while the preform extrusion assembly remains stationary as an example, when the forming device is located below the preform extrusion assembly, production can proceed, completing a one-step closed aseptic production process encompassing extrusion, forming, filling, sealing, and demolding. When maintenance is required on the preform extrusion assembly and filling mechanism, the forming device is moved away from below the preform extrusion assembly. The area below the preform extrusion assembly then serves as a maintenance workspace, eliminating the need for the preform extrusion assembly and filling mechanism to move to a non-clean area, thus avoiding the risk of environmental contamination. The structure is simple and rational. When production is required after maintenance, the forming device simply moves back below the preform extrusion assembly.

[0020] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] Figure 2 , Figure 3 and Figure 6 This illustration shows one embodiment of the blow-fill-seal integrated machine of the present invention. The machine includes a clean area 1, which is equipped with a preform extrusion assembly 4, a filling mechanism 5 inserted into the preform extrusion assembly 4, and a forming device 6 located below the preform extrusion assembly 4. The forming device 6 can be moved to two different positions within the clean area 1, one for production and the other for non-production tasks. In other embodiments, the position of the forming device 6 within the clean area 1 can be further increased.

[0040] In this embodiment of the blow-fill-seal integrated machine, the forming device 6 can move between two different positions within the clean area 1, such as... Figure 2 As shown, when located below the preform extrusion assembly 4, production can commence, achieving a closed, aseptic production process that completes extrusion, molding, filling, sealing, and demolding in one step. Figure 3 As shown, when maintenance is required on the preform extrusion assembly 4 and the filling mechanism 5, the forming device 6 is moved away from below the preform extrusion assembly 4. At this time, the area below the preform extrusion assembly 4 can serve as a maintenance workspace. The preform extrusion assembly 4 and the filling mechanism 5 themselves do not need to move, avoiding the risk of environmental contamination from the non-clean area 2. Simultaneously, it prevents the clean area 1 from connecting with the non-clean area 2, thus avoiding contamination of the clean area 1. The structure is simple and reasonable. When production is required after maintenance, the forming device 6 simply moves back to below the preform extrusion assembly 4.

[0041] In this embodiment, a non-clean area 2 is provided on one side of the clean area 1. Figure 2 and Figure 3 The non-clean area 2 is located to the right of the clean area 1. The clean area 1 and the non-clean area 2 are separated by a partition 3. The non-clean area 2 is equipped with an extrusion screw assembly 8. The discharge end of the extrusion screw assembly 8 passes through the partition 3 and connects with the preform extrusion assembly 4. The clean area 1 is equipped with a translation drive mechanism 7. The forming device 6 is connected to the translation drive mechanism 7 to move back and forth in the clean area 1. That is, the translation drive mechanism 7 drives the forming device 6 to move back and forth.

[0042] Furthermore, in this embodiment, the moving direction of the translation drive mechanism 7 is parallel to the length direction of the extrusion screw assembly 8. Figure 2 and Figure 3 When maintenance is required on the preform extrusion assembly 4 and the filling mechanism 5, the forming device 6 moves to the left to make room under the preform extrusion assembly 4. When production is required after maintenance, the forming device 6 moves to the right back under the preform extrusion assembly 4.

[0043] In a preferred embodiment, the partition 3 is a partition wall. The partition wall can effectively separate the clean area 1 from the non-clean area 2, and its structure is sturdy and reliable. Of course, in other embodiments, the partition 3 can also be a partition plate, etc.

[0044] See details Figure 6 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 mounted on the slide 73 and meshing with the rack 72. The guide rail 71 is arranged parallel to the extrusion screw assembly 8, and the forming device 6 is mounted on the slide 73. During operation, the drive gear 74 rotates and rolls along the rack 72, thereby driving the slide 73 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 forming device 6 reciprocates with the slide 73, resulting in a simple and reliable structure. Of course, in other embodiments, the slide 73 can also be driven to reciprocate along the guide rail 71 by a cylinder, hydraulic cylinder, screw and nut assembly, etc., which will not be described in detail here.

[0045] In a preferred embodiment, the guide rail 71 has two rows that are spaced apart, which can provide stable support and guidance for the slide 73 and the forming device 6, ensuring stable and reliable movement.

[0046] Example 2

[0047] Figure 4 and Figure 5Another embodiment of the blow-fill-seal integrated machine of this utility model is shown. This embodiment is basically the same as the first embodiment, except that:

[0048] The moving direction of the molding device 6 is perpendicular to the length direction of the extrusion screw assembly 8. Correspondingly, the moving direction of the molding device 6 in this embodiment is perpendicular to the moving direction of the molding device 6 in Embodiment 1. When it is necessary to maintain the preform extrusion assembly 4 and the filling mechanism 5, the molding device 6 can move along the direction perpendicular to the paper surface, which can also make room for the space below the preform extrusion assembly 4.

[0049] Of course, in other embodiments, the direction of movement of the forming device 6 can also be adjusted, for example, the angle between it and the length direction of the extrusion screw assembly 8 is 45°, or the forming device 6 can move along the length direction of the extrusion screw assembly 8 or in a direction perpendicular to the length direction of the extrusion screw assembly 8, or make room for the space below the tube preform extrusion assembly 4.

[0050] Example 3

[0051] Figures 7 to 9 Another embodiment of the blow-fill-seal integrated machine of this utility model is shown. In this embodiment, the blow-fill-seal integrated machine further includes a movable seat assembly 9, one end of which is located in the clean area 1 and the other end in the non-clean area 2. A preform extrusion assembly 4 is located at the end of the movable seat assembly 9 located in the clean area 1, and an extrusion screw assembly 8 is located at the end of the movable seat assembly 9 located in the non-clean area 2. The non-clean area 2 is provided with a translation drive mechanism 7, which is connected to the movable seat assembly 9 to drive the preform extrusion assembly 4 and the filling mechanism 5 to reciprocate within the clean area 1. The translation drive mechanism 7 located in the non-clean area 2 can drive the preform extrusion assembly 4 and the filling mechanism 5 to move within the clean area 1 via the movable seat assembly 9. After the preform extrusion assembly 4 and the filling mechanism 5 are moved away from above the molding device 6, a space can also be formed below the preform extrusion assembly 4 for maintenance or other tasks, and the preform extrusion assembly 4 and the filling mechanism 5 can be prevented from being contaminated when they move to the non-clean area 2.

[0052] See details Figure 8 and Figure 9In this embodiment, the translation drive mechanism 7 includes a guide rail 71, a rack 72 arranged parallel to 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. The moving seat assembly 9 is located at one end of the non-clean area 2 and is mounted on the guide rail 71. The drive gear 74 is mounted on the moving seat assembly 9. During operation, the drive gear 74 rotates and rolls along the rack 72, thereby driving the moving seat assembly 9 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 moving seat assembly 9, making the movement process smooth and stable. The preform extrusion assembly 4 and the filling mechanism 5 move with the moving seat assembly 9 to the side away from the non-clean area 2. Figure 8 (Left side of the middle), with a simple and reliable structure.

[0053] In a preferred embodiment, the guide rail 71 has two rows, the rack 72 has two racks located inside the two rows of guide rails 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 moving seat assembly 9 and the tube preform extrusion assembly 4, filling mechanism 5 and extrusion screw assembly 8 installed on it.

[0054] Example 4

[0055] Figures 10 to 11 Another embodiment of the blow-fill-seal integrated machine of this utility model is shown. This embodiment is basically the same as embodiment three, except that:

[0056] In this embodiment, the moving direction of the preform extrusion assembly 4 and the filling mechanism 5 is perpendicular to the length direction of the extrusion screw assembly 8. The separator 3 is provided with a notch 31 for the moving seat assembly 9 and the extrusion screw assembly 8 to move. The separator 3 is provided with a sliding door 32 on at least one side for sealing the notch 31 (preferably, the sliding door 32 is located in the non-clean area 2, but in other embodiments, the sliding door 32 can also be located in the clean area 1). The moving seat assembly 9 and the extrusion screw assembly 8 pass through the sliding door 32. When the translation drive mechanism 7 drives the preform extrusion assembly 4 and the filling mechanism 5 to move laterally in the clean area 1 through the moving seat assembly 9, the notch 31 on the separator 3 will not be obstructed. The sliding door 32 is used to ensure the sealing of the notch 31 after the extrusion screw assembly 8 and the moving seat assembly 9 move laterally. The structure is reasonable and effective.

[0057] Furthermore, 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 perpendicularly to the extrusion screw assembly 8, the drive gear 74 is mounted on the slide 73, and the moving seat assembly 9 is located at one end of the non-clean area 2 and mounted on the slide 73. During operation, the drive gear 74 rotates and rolls along the rack 72, thereby driving the slide 73 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 process smooth and stable. The moving seat assembly 9 moves back and forth with the slide 73, while the preform extrusion assembly 4 and the filling mechanism 5 move laterally in the clean area 1. An operating space for maintenance can be formed below the preform extrusion assembly 4, resulting in a simple and reliable structure.

[0058] See details Figure 10 Furthermore, in this embodiment, the movable seat assembly 9 includes a first movable seat 91, a second movable seat 92, and a third movable seat 93 arranged sequentially along the length of the extrusion screw assembly 8. The first movable seat 91 and the second movable seat 92 are located in the non-clean area 2 and distributed at both ends of the extrusion screw assembly 8. One end of the third movable seat 93 is located in the clean area 1, and the other end passes through the separator 3 and is connected to the second movable seat 92. The modular movable seat assembly 9 can provide reliable support for the preform extrusion assembly 4, the filling mechanism 5, and the extrusion screw assembly 8, enabling the three to move as a whole, and can reduce the weight of the movable seat assembly 9 itself, making it convenient to move.

[0059] Example 5

[0060] The above embodiments can be combined with each other, moving the preform extrusion assembly 4 and the filling mechanism 5 simultaneously while moving the molding device 6. Only the positional space needs to be changed within the clean area 1 to provide maintenance and repair space below the preform extrusion assembly 4. For example:

[0061] The moving direction of the molding device 6 is as follows Figure 3 As shown, the moving directions of the preform extrusion assembly 4 and the filling mechanism 5 are as follows: Figure 11 As shown, the directions of movement are perpendicular to each other;

[0062] Alternatively, the direction of movement of the molding device 6 is as follows: Figure 5 As shown in the figure, the moving directions of the preform extrusion assembly 4 and the filling mechanism 5 are as follows: Figure 8 As shown in the figure, it is perpendicular to the moving direction of the molding device 6, but it can also be as shown in the figure. Figure 11 As shown, the direction of movement is opposite to that of the forming device 6. Other connection methods follow the same principle and will not be described in detail.

[0063] 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.
