Description

Technical Field

[0001] This utility model relates to the technical field of high-speed heavy film FFS packaging machine equipment, and in particular to a combined frame for a high-speed heavy film FFS packaging machine. Background Technology

[0002] The high-speed heavy-duty film FFS packaging machine is a fully automatic packaging equipment. Its full name is "Form-Fill-Seal" packaging machine, primarily used for packaging powders and granules. It uses a series of automated processes to form bags from packaging materials, fill them with the material, and seal them, ultimately completing the packaging task. This equipment plays a vital role in modern industry, especially in improving production efficiency, reducing labor costs, and ensuring packaging quality, as follows.

[0003] A search revealed a patent with publication number CN115447841A, which discloses a novel FFS heavy film packaging machine. The machine comprises a frame (1); a film feeding device (4) connected to the frame (1); a film supporting mechanism (3) mounted on the frame (1); a coding device (2); a positioning mechanism (5); a swing mechanism (9); a forming device (13); a centering device (6); a film pulling device (7); a horizontal support device (8); and an encoder (10) hinged to the top of the film pulling device (7). The encoder (10) detects the film movement speed signal and feeds it back to the servo motor (42) of the film feeding device (4), thereby adjusting the rotational speed of the servo motor (42) to coordinate the film feeding speed with the film pulling speed. During operation, the packaging film achieves resistance-free film feeding and high positioning accuracy.

[0004] As mentioned above, in the traditional design of high-speed heavy-duty FFS packaging machines, the frame is mostly made of integral welding or a single structure, which has problems with insufficient structural rigidity and stability. Especially under high-speed operation, it is prone to dynamic vibration, resulting in a decline in packaging quality and a shortened equipment life. At the same time, the non-removable nature of traditional frames makes transportation, installation and maintenance costs high, and the existing design lacks modular expansion capabilities, making it difficult to quickly adjust the frame layout according to different packaging specifications. This leads to poor production line adaptability, long upgrade cycles, and an inability to meet the market demand for flexible production. Therefore, there is an urgent need for a modular frame for high-speed heavy-duty FFS packaging machines to solve the above-mentioned technical problems. Utility Model Content

The frame components are equipped with ribs, bolt connections, and shock-absorbing pads, which can effectively reduce vibration during the packaging machine production process. The modular design facilitates installation, disassembly, and transportation, and can meet the needs of rapid switching between different models or specifications of packaging tasks. It shortens the changeover and debugging time and improves packaging production efficiency. In summary, it solves the problems in the background technology.
