Abstract
Description
Technical Field
[0001] This utility model relates to the field of film expansion machine technology, and more specifically, to a film expansion machine for product packaging. Background Technology
[0002] A film expander, as the name suggests, is a machine capable of enlarging or adjusting the size and shape of packaging film. In the packaging process, it is typically used in conjunction with other packaging equipment (such as vacuum packaging machines and stretch wrapping machines) to achieve effective product packaging. The working principle of a film expander is primarily based on mechanical transmission and a control system. Driven by a motor, the expander expands and positions the packaging film. The control system monitors and adjusts the operating status of the expander to ensure that the size and shape of the packaging film meet the requirements of the product packaging. Existing product packaging film expanders may experience wrinkles, twists, or other issues due to the film's own weight or external forces, affecting the expanding effect and quality. This can lead to areas where the film is too thin or too thick, impacting the quality and appearance of the packaging, thus requiring improvement. Utility Model Content

At this time, the feeding mechanism transports the material. When it reaches the guiding mechanism, there is a forward thrust. Due to the fast speed of the film output and the slow speed of the collection mechanism, the material is wrapped by the film. Then the sealing mechanism inside the sealing box seals the edge.

[0022] The operator directs the film from the film-exiting machine to be laid flat on the top of the inner wall of the film expander 3, and then the film is supported by the film-supporting mechanism. Then, the film is guided by the guiding mechanism so that it can be smoothly wound by the collecting mechanism. At this time, the feeding mechanism transports the material. When it reaches the guiding mechanism, there is a forward thrust. Due to the fast speed of the film exiting and the slow speed of the collecting mechanism, the material is wrapped by the film. Then, the sealing mechanism inside the sealing box 17 seals the edges, and then the unloading mechanism unloads the material.
[0023] The film passes through the top of the inner wall of the film expander 3, and is then supported by the film support mechanism. The film is then guided by the guiding mechanism so that it can be smoothly wound by the collecting mechanism. At this time, the feeding mechanism transports the material. When it reaches the guiding mechanism, there is a forward thrust. Due to the fast speed of the film exiting and the slow speed of the collecting mechanism, the material is wrapped by the film. Then, the sealing mechanism inside the sealing box 17 seals the edges. Compared with traditional devices, this device can effectively reduce the misalignment between the film and the product packaging process, reduce the film wear rate, improve the film yield, reduce the cost caused by misalignment, reduce the time for equipment maintenance, and speed up the work efficiency.

[0037] Working principle and usage process of this utility model:
[0038] The operator directs the film from the film-exiting machine to be laid flat on the top of the inner wall of the film expander 3, and then the film is supported by the film-supporting mechanism. Then, the film is guided by the guiding mechanism so that it can be smoothly wound by the collecting mechanism. At this time, the feeding mechanism transports the material. When it reaches the guiding mechanism, there is a forward thrust. Due to the fast speed of the film exiting and the slow speed of the collecting mechanism, the material is wrapped by the film. Then, the sealing mechanism inside the sealing box 17 seals the edges, and then the unloading mechanism unloads the material.
