Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, and in particular to a mold closing adjustment mechanism for a BFS (Blow-Off Form) device. Background Technology

[0002] Currently, Blow-Fill-Seal (BFS) technology is recognized as an energy-saving, environmentally friendly, and high-value-added aseptic process. BFS aseptic filling production lines have been widely used in the production of aseptic pharmaceuticals, aseptic functional foods, and aseptic cosmetics. This article briefly introduces the concept, process layout, and aseptic preparation system of the BFS aseptic filling production line, and analyzes its unique characteristics from the perspectives of risk prevention and practical application.

[0003] The Blow / Fill / Seal (BFS) aseptic filling production line consists of a set of aseptic preparation systems and a BFS aseptic filling machine, and is currently a relatively complete aseptic filling production line. This production line has full CIP / SIP functionality and operates under positive pressure, closed-loop, and laminar flow protection. Container fabrication, product filling, and container sealing are all completed under the aseptic protection of a Class A air shower, effectively preventing various contaminations and cross-contaminations that may occur during the process. Process parameters such as temperature, pressure, pH, weight, and time / speed can be monitored online and recorded in real time, fully meeting the requirements of aseptic processes. Due to the strong aseptic assurance capability of the BFS aseptic filling production line, no preservatives need to be added to the product, achieving "non-terminal sterilization," resulting in high product intrinsic quality and good safety.

[0004] Currently, BFS (Bare-Filtration-Site) technology is recognized as an energy-saving, environmentally friendly, and high-value-added aseptic process. BFS aseptic filling production lines have been successfully applied in the production of aseptic pharmaceuticals, aseptic functional foods, and aseptic cosmetics.

[0005] Currently, there are two main types of mold closing devices in blow-fill-seal equipment. The first type uses hydraulic cylinders with different diameters on the left and right sides of the mold closing mechanism, which requires adjusting the adjusting flange on the side of the mold closing hydraulic cylinder to achieve precise control of the mold closing position. The second type uses a linkage mechanism for locking, which requires a complex auxiliary mechanism to eliminate gaps. This type has many parts and a complex mechanism. Utility Model Content

[0022] like Figures 1 to 3 The BFS device shown includes a mold closing adjustment mechanism, comprising a fixed inner mold 1, a movable outer mold 2, and a fixed column 3. Multiple sets of fixed inner molds 1 are arranged in a circular array around the fixed column 3. Each set of fixed inner molds 1 has a mold closing groove on its outer wall. Each set of fixed inner molds 1 is correspondingly provided with a movable outer mold 2. The inner wall of the movable outer mold 2 is also symmetrically provided with a mold closing groove relative to the outer wall of the fixed inner mold 1. The inner wall of the movable outer mold 2 is sealed and fitted to the outer wall of the fixed inner mold 1 through an adjustment component. The movable outer mold 2 moves up and down along the outer periphery of the fixed inner mold 1.

[0023] Each set of fixed inner molds 1 is a triangular pyramid structure. One edge of multiple sets of fixed inner molds 1 is vertically and fixedly connected to the outer wall of the fixed column 3. Adjacent fixed inner molds 1 are fitted together to form a multi-prism structure.

[0024] The adjustment assembly includes a mounting base 4 and an adjustment plate 5. The mounting base 4 has an annular groove inside, and multiple sets of fixed inner molds 1 are vertically arranged in the annular groove. The adjustment plate 5 is rotatably installed inside the annular groove of the mounting base 4. The movable outer molds 2 are arranged in a ring array and slide relative to each other in the mounting base 4 below the adjustment plate 5. The adjustment plate 5 has an annular structure, and each set of movable outer molds 2 is provided with an arc groove 6 in the circumferential direction. The top of the movable outer mold 2 is provided with a slider 7 in the arc groove 6, and the slider 7 moves along the arc groove 6.

[0025] A worm gear 8 is fixedly installed at the outer end of the adjusting plate 5 inside the mounting base 4. An adjusting motor 9 is installed at one end of the worm gear 8 inside the mounting base 4. A worm 10 is installed at the output end of the adjusting motor 9 and meshes with the worm gear 8 for transmission. By driving the adjusting motor 9, the worm 10 meshes with the worm gear 8 for transmission, thereby driving the adjusting plate 5 to rotate. The movable outer mold 2 is realized under the limited movement of the slider 7.

[0026] Both the fixed inner mold 1 and the movable outer mold 2 have semi-circular holes 11 at their upper sealing and fitting ends, and the two sets of semi-circular holes 11 form the mold opening.

[0027] The mounting base 4 is provided with a lifting rail 12 at the end away from the adjusting motor 9. The mounting base 4 and the lifting rail 12 move up and down relative to each other through a linear motor 13. The mounting base 4 rises and falls along the lifting rail 12 through the linear motor 13, which facilitates maintenance and protection.

[0028] The mounting base 4 has two sets of guide columns 14 near the adjusting motor 9. The mounting base 4 also has two sets of guide seats 15. The guide seats 15 are movably mounted on the guide columns 14. The guide columns 14 and guide seats 15 can realize the stable lifting of the device and at the same time prevent the fixed inner mold 1 and the movable outer mold 2 from shifting, which would lead to a decrease in mold closing accuracy.

[0029] Mounting base 4 is offset vertically from fixed inner mold 1 at both the lowest and highest stroke heights to facilitate subsequent maintenance and protection.

[0030] This invention enables multiple movable outer molds to be simultaneously centered and clamped by adjusting the components, thereby achieving mold closing operation with the fixed inner mold. Multiple mold closing operations can be completed with only one set of drive equipment. The device has a simple structure and can achieve precise control of the position of multiple mold sets.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
