Abstract
Description
Technical Field
[0001] This utility model relates to the field of aseptic packaging technology, and in particular to a partition component suitable for continuous batch-free packaging (BFS). Background Technology
[0002] The blow-fill-seal (BFS) production line utilizes a specialized aseptic packaging technology for continuous operation. It automatically processes medical-grade polyethylene (PE) or polypropylene (PP) granules into containers, completing the filling and sealing process in a rapid, continuous cycle. It integrates several manufacturing processes into a single, aseptic step, ensuring the safe use of the plastic containers. This equipment offers advantages such as low production and management costs, excellent aseptic stability, high finished product quality, and low risk of cross-contamination. It can be widely used in the production of terminally sterilized and aseptic products in the plastic packaging industry.
[0003] Extruders are key equipment in plastic container molding. Typically, the extruder body (including the motor, transmission, and feeding system) generates noise, vibration, and dust, while the extrusion head (including the die) needs to operate in a highly clean environment to ensure product quality. Therefore, the main body of the extruder and the extrusion head are often placed in two rooms with different cleanliness levels: a clean area and a non-clean area. During processing, the extrusion head enters the clean area from the non-clean area; after processing, it returns to the non-clean area. In existing technology, the clean area and the non-clean area are usually a simple fixed opening or a manually operated cover. Fixed openings cannot effectively isolate the airflow between the two areas, disrupting the pressure difference and cleanliness of the clean area. Manually operating the cover is inefficient, cannot be linked to the equipment, and increases the risk of human contamination. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a partition component suitable for continuous BFS.
[0005] The technical solution of this utility model is a partition component suitable for continuous BFS, including a guide rail and an openable door panel arranged along the clean area and the non-clean area. The door panel slides relative to the guide rail to switch the connection state between the clean area and the non-clean area. The lower part of the door panel is provided with an opening that matches the shape of the extrusion head, and a movable plate that can move up and down in the vertical direction is provided on the opening; the movable plate is controlled to rise and fall by a lifting assembly. When the movable plate rises, the opening opens, and the extrusion head enters the clean area from the non-clean area through the opening; after the extrusion head exits the opening, the opening closes when the movable plate falls.
[0006] Preferably, a first handle for easy gripping is provided on the door panel; a second handle of the same type is provided on the movable panel.
[0007] Preferably, two vertically extending clips are provided on the side of the door panel facing the clean area, and the two clips are parallel to each other; When the movable plate moves up and down, it cooperates with the clamping plate to form a limiting structure.
[0008] Preferably, the lifting assembly is an electric push rod; it is installed on the door panel and located on both sides of the opening; the output end of the electric push rod is connected to the movable plate, pushing the movable plate to drive the movable plate to move up and down.
[0009] Preferably, the lifting assembly includes a base, a motor compartment, a protective housing, and an output shaft; The base provides a support platform for the entire lifting assembly, and the base is fixed to the door panel; The motor housing and protective shell are both located on the base; the protective shell extends upward to the bottom of the plate; the output shaft extends out from the protective shell and is located inside the plate; a connector is provided on the top of the output shaft, and fasteners are used to secure the connector to the bottom of the movable plate.
[0010] Preferably, a guide groove extends upward along the mounting position of the card plate on the door panel; a retaining strip is provided on the output shaft to cooperate with the guide groove; during the up and down movement of the output shaft, the retaining strip is always engaged in the guide groove to limit the output shaft.
[0011] Preferably, the end of the output shaft that is inserted into the protective shell is a round rod, and the end that extends to the clamping plate is a flat plate-like structure.
[0012] Preferably, a bottom plate is provided at the bottom of the door panel, and the bottom plate extends outward to one side of the clean area; The movable plate moves downwards, closing the opening, and then its bottom contacts the base plate; the base plate supports the movable plate while simultaneously sealing the opening.
[0013] Preferably, an embedded second identification area and a first identification area are respectively set at the installation position near the door panel in both the clean area and the non-clean area.
[0014] Preferably, an observation window is provided on the door panel, and an electromagnet is provided at the bottom of the observation window; when the electromagnet is energized, it generates a magnetic attraction force to attract the movable plate.
[0015] Compared with the prior art, the present invention has the following beneficial technical effects: By improving the existing door panel, an opening similar in shape and size to the extruder head is created on the door panel, and a movable plate that can move up and down is installed. Compared with the flip-type opening and closing method, the space required for opening and closing the door is reduced. The opening and closing of the opening are achieved by controlling the up and down movement of the movable plate through the lifting component. With the recognition signal of the recognition area, automatic sensing opening and closing of the door can be realized, reducing the tedious operation of manual opening and reducing mutual interference between clean and non-clean areas.

[0018] Example
[0019] like Figure 1 As shown, the present invention proposes a partition component suitable for continuous BFS (Browser-Free System), including a guide rail 3 and an openable door panel 2 arranged along the clean area and the non-clean area. The door panel 2 slides relative to the guide rail 3 to switch the connection state between the clean area and the non-clean area. In traditional production workshops, when the extruder needs to enter the clean area from the non-clean area, it needs to be manually operated. The first handle 4 is held to slide the entire door panel 2 along the guide rail 3 to open the door panel 2, making it convenient for the extruder to enter. After processing is completed, the door panel 2 is manually closed. Therefore, during the processing, the clean area and the non-clean area are in a completely open state, which can easily damage the cleanliness of the clean area.
[0020] This invention, based on the existing door panel 2, adds an opening 10 at the bottom of the door panel 2 that matches the shape of the extruder head, and a movable plate 5 that can move up and down in the vertical direction is provided on the opening 10. The extruder head can enter and exit by opening and closing the movable plate 5, without having to open or close the entire door panel 2. When the extruder head is working, the opening 10 is close to the position of the extruder head, and additional equipment such as an air curtain can be set to isolate the airflow passage.
[0021] In this embodiment, the movable plate 5 is controlled to rise and fall by the lifting assembly 9. When the movable plate 5 rises, the opening 10 opens, and the extruder head enters the clean area from the non-clean area through the opening 10. After the extruder head exits the opening 10, when the movable plate 5 falls, the opening 10 closes. Figure 3 As shown, two clamping plates 8 extending vertically are provided on the side of the door panel 2 facing the clean area, and the two clamping plates 8 are kept parallel to each other; when the movable plate 5 moves up and down, it cooperates with the clamping plates 8 to form a limiting structure.
[0022] like Figure 4-6 As shown, the lifting assembly 9 is an electric push rod; it is mounted on the door panel 2 and located on both sides of the opening 10; the output end of the electric push rod is connected to the movable plate 5, pushing the movable plate 5 to drive the movable plate 5 to move up and down. The lifting assembly 9 includes a base 93, a motor compartment 92, a protective shell 91, and an output shaft 94; the base 93 provides a support platform for the entire lifting assembly 9, and the base 93 is fixed to the door panel 2; the motor compartment 92 and the protective shell 91 are both located on the base 93; the protective shell 91 extends upward to the bottom of the clamping plate 8; the output shaft 94 extends out from the protective shell 91 and is located inside the clamping plate 8; a connector 95 is provided on the top of the output shaft 94, and fasteners are used to securely connect the connector 95 to the bottom of the movable plate 5. The lifting assembly 9 uses a general-purpose electric actuator. In this application, the lifting assembly 9 is merely an exemplary solution for realizing the up and down movement of the movable plate 5. This application does not involve any improvement to the internal transmission structure, power supply circuit, or control circuit of the lifting assembly 9. The relevant transmission structure, power supply circuit, and control circuit can refer to the structure of ordinary electric actuators on the market, and the applicant will not elaborate on them here.
[0023] As a preferred embodiment, in this case, a guide groove extends upward from the mounting position of the door panel 2 along the mounting plate 8; a retaining strip 941 that mates with the guide groove is provided on the output shaft 94; during the up-and-down movement of the output shaft 94, the retaining strip 941 is always engaged in the guide groove, limiting the movement of the output shaft 94. The end of the output shaft 94 that inserts into the protective shell 91 is a round rod, and the end that extends to the mounting plate 8 is a flat plate structure. When the lifting assembly 9 controls the movable plate 5 to move upward, one side of the retaining strip 941 in the output shaft 94 is engaged in the guide groove, while the other side is a smooth surface that moves against the inner wall of the mounting plate 8; this can limit the movement of the entire output shaft 94, prevent displacement, reduce vibration, and make the up-and-down movement of the movable plate 5 more stable.
[0024] As a preferred embodiment, such as Figure 1-2 As shown, a bottom plate 11 is provided at the bottom of the door panel 2. The bottom plate 11 protrudes outward and extends to one side of the clean area. When the movable plate 5 moves downward and closes the opening 10, the bottom contacts the bottom plate 11. The bottom plate 11 supports the movable plate 5 and can seal the opening 10 at the same time, improving the overall airtightness.
[0025] As a preferred embodiment, such as Figure 1 As shown, embedded second identification area 7 and first identification area 6 are respectively installed near the door panel 2 in both the clean and non-clean areas. Microwave sensors capable of detecting the position of the extruder head are installed in the first and second identification areas; this enables automatic activation when the extruder head approaches and automatic deactivation when it exits. The signal detection and control principle of the microwave sensor and controller can refer to the principle of common automatic doors on the market. This application does not involve any improvement to the control principle or control circuit. The first and second identification areas are only used to generate an approach signal for the extruder head. For example, when the extruder head needs to enter the clean area, it first moves to the second identification area 7. The second identification area 7 receives an approach signal and then controls the movable plate 5 to open through the upper controller. The extruder head continues to move to the first identification area 6. The first identification area 6 receives an approach signal and then controls the lifting assembly 9 to de-energize through the upper controller, entering a standby state. When the extruder head needs to exit the clean area, similar to when entering, after the first identification area 6 loses its approach signal, the upper controller controls the lifting assembly to be energized. After the second identification area 7 also loses its approach signal, the lifting assembly 9 is controlled to descend, causing the movable plate 5 to move downward and close the opening 10. This application does not involve any improvement to the control program of the upper controller and the lifting assembly 9, but only introduces the improvement points of this application as an exemplary solution.
[0026] In this embodiment, an observation window 1 is provided on the door panel 2, and an embedded electromagnet can be provided at the lower part of the observation window 1; when the electromagnet is energized, it generates a magnetic attraction force to attract the movable plate 5; when the lifting assembly 9 is raised to the highest position and de-energized, the built-in electromagnet can be energized to generate a magnetic attraction force to attract the movable plate 5, thereby improving safety.
[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
