The lifting module 62 is disposed on the fixed support 61. The movable support 63 is connected to the driving end of the lifting module 62 so as to drive the movable support 63 up and down through the lifting module 62. The unwinding module 64, the film stretching module 65, and the winding module 66 are all disposed on the fixed support 61. The winding module 66 is provided with a servo drive motor 661 for winding the film to a fixed length. The film stretching module 65 is used to stretch the film above the placement assembly 7. The ultrasonic welding assembly 5 is synchronously driven with the lifting module 62 to ultrasonically weld the film to the product. This embodiment uses a winding module 66 controlled by a servo drive motor 661 to achieve precise winding of the film to a fixed length, effectively avoiding errors in traditional manual operations and improving production efficiency and product quality consistency. The film stretching module 65 ensures that the film maintains uniform tension during the stretching process and is precisely positioned above the placement component 7, reducing problems such as wrinkles and offsets in the film and improving welding quality. The ultrasonic welding component 5 and the lifting module 62 achieve synchronous transmission to ensure that ultrasonic welding is performed immediately while the film accurately covers the surface of the product, greatly shortening the production cycle and improving production efficiency. At the same time, this synchronization also ensures the accuracy and stability of welding. The setting of the adjustment component 3 allows for rapid adjustment according to the size and requirements of different products, enhancing the versatility and flexibility of the equipment. The combination of the column 4 and the ultrasonic welding component 5 further enhances the spatial freedom of the welding operation and meets diversified production needs. This embodiment provides strong technical support for modern industrial production through its high efficiency, precision and flexibility.

[0027] A bracket 21 is provided on one side of the workbench 2, located on the side where the assembly 7 is placed. This bracket 21 is provided with a frame groove 22, which is located on the periphery of the assembly 7. In this embodiment, the establishment of the bracket 21 and its frame groove 22 effectively improves the stability and safety of the film roll placement, ensures the precise positioning and fixation of the film roll material during welding, and reduces welding quality issues caused by material offset. Secondly, the design of the frame groove 22 facilitates the rapid loading and unloading and positioning adjustment of the film roll before and after welding, improving production efficiency and operational flexibility. Furthermore, this structure optimizes the space utilization of the workbench 2, making the overall device structure more compact and reasonable, and facilitating maintenance and management.

[0028] The placement assembly 7 is provided with a placement slot 71, and a clamping cylinder 72 is provided on one side of the placement slot 71. The clamping cylinder 72 is used to compress and fix the product to the placement slot 71. In this embodiment, the placement slot 71 is customized to adapt to the shape and size of the product, ensuring stable positioning of the product during the welding process and reducing poor welding caused by positional offset. The clever use of the clamping cylinder 72 achieves efficient compression and fixation of the product by precisely controlling the applied pressure, effectively preventing the product from shaking or shifting under ultrasonic high-frequency vibration, and ensuring close contact at the welding interface and uniform energy transfer.

[0029] The adjustment assembly 3 includes a first direction adjustment module 31 and a second direction adjustment module 32. The first direction adjustment module 31 is arranged on the workbench 2, the second direction adjustment module 32 is arranged on the first direction adjustment module 31, and the column 4 is arranged on the second direction adjustment module 32. In this embodiment, the first direction adjustment module 31 is firmly mounted on the workbench 2 as a basic adjustment layer to ensure the stability of the overall structure; while the second direction adjustment module 32 is cleverly superimposed thereon, further realizing the ability of multi-dimensional subtle adjustments. This stacked design not only optimizes space utilization, but also enables the column 4 (i.e., the support structure of the ultrasonic welding head) to achieve precise alignment and fine-tuning in the two key dimensions of horizontal and vertical, thereby effectively meeting the welding needs of roll film of different specifications and sizes.

[0030] A height adjustment module 41 is provided on the column 4, and the height adjustment module 41 is connected to the ultrasonic welding module and is used to adjust the height of the ultrasonic welding module.

[0031] The lifting module 62 includes a lifting cylinder 621, a lifting slider 622, and a lifting connector (not shown). The lifting cylinder 621 is mounted on a fixed bracket 61, and the movable bracket 63 is slidably mounted on the lifting slider 622. One end of the lifting connector is connected to the lifting cylinder 621, and the other end is connected to the movable bracket 63. In this embodiment, an adjustment mechanism enables flexible adjustment of the welding module height. This design not only significantly enhances the adaptability and flexibility of the equipment, but also ensures that the optimal welding position can be achieved during the welding of roll film of different specifications and thicknesses, thereby optimizing welding quality and reducing the defective rate.

[0032] The unwinding module 64 includes an unwinding drive element 641 and an unwinding roller 642. An unwinding guide roller 643 is provided below the unwinding roller 642. The driving end of the unwinding drive element 641 is connected to the unwinding roller 642 and is used to unwind the film material onto the unwinding guide roller 643. The unwinding guide roller 643 is used to guide the film material toward the film stretching module 65. The film stretching module 65 includes a first stretching roller 651 and a second stretching roller 652. The first stretching roller 651 and the second stretching roller 652 are arranged opposite each other and are used to stretch the film material above the placement assembly 7. The first stretching roller 651 is provided with a first gear ring 653, and the second stretching roller 652 is provided with a second gear ring 654. There are two of each of the first gear ring 653 and the second gear ring 654, which are used to limit the width direction of the film material. The winding module 66 is provided with a winding roller 662 and a winding guide roller 663. The driving end of the servo drive motor 661 is connected to the winding roller 662, and the winding guide roller 663 is used to guide the film material toward the winding roller 662. In this embodiment, the unwinding module 64 cooperates with the guide roller through the precisely controlled unwinding drive element 641 to ensure that the film material enters the stretching stage smoothly and without tension fluctuations, laying a solid foundation for subsequent processing. In the film material stretching module 65, the first and second stretching rollers 652 and their matching double-gear ring design not only effectively limit the deviation of the film material in the width direction, but also achieve uniform stretching of the film material through relative arrangement, enhancing the flatness and dimensional stability of the film material, which is crucial for precise docking during ultrasonic welding. Finally, the winding module 66 achieves high-precision winding of the film material with the help of the synergistic effect of the servo drive motor 661 and the guide roller, ensuring the tightness and consistency of the finished roll film. Overall, this structural design significantly improves the operating accuracy, production efficiency and product quality of the ultrasonic welding fixed-length film roll device, meeting the needs of high-precision and high-efficiency industrial production.
