[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4This utility model provides a technical solution: a convenient sealing bag making equipment for food packaging composite film bags, including an operating table 1. The bottom of the operating table 1 is symmetrically equipped with supports 2. The top of the operating table 1 is equipped with a sealing mechanism 3 consisting of a control panel 31, a lower pressure arm 32, and a heating plate 33. A foot pedal mechanism 4 is provided between the supports 2. The foot pedal mechanism 4 consists of a foot pedal rod 41, a connecting plate 42, and a foot pedal 43. The bottom end of the foot pedal rod 41 is a telescopic structure, and its telescopic part can be fixed by screws. The top end of the foot pedal rod 41 passes through the operating table 1 and is connected to the lower pressure arm 32. The connecting plate 42 is fixed to the bottom end of the foot pedal rod 41, and the foot pedal 43 is fixed to the front end of the connecting plate 42. A lifting adjustment mechanism 5 is provided between the bottom ends of the supports 2 for adjusting the vertical position of the bottom end of the foot pedal mechanism 4. Furthermore, an adjustable-compression return spring 6 is fitted at the bottom of the connection between the foot pedal 41 and the operating table 1. When the operator presses down on the foot pedal 43 of the foot pedal mechanism 4, the foot pedal 41 moves downward, causing the lower pressure arm 32 to descend. The heating plate 33 on the lower pressure arm 32 contacts the area on the composite film bag that needs to be sealed, completing the sealing operation through heating and pressurization. After sealing, the operator releases the foot pedal 43, at which point the return spring 6 provides a restoring force through its adjustable compression, helping the foot pedal 41 and its connected components to quickly return to their original position, preparing for the next sealing operation. The compression degree of the return spring 6 can be adjusted according to operational needs, ensuring that a suitable restoring force is provided after each operation, without being excessively strong. While strong vibrations may damage the equipment, they can also slightly affect operational efficiency. Simultaneously, the lifting and adjusting mechanism 5 can drive the bottom of the foot pedal mechanism 4, allowing the vertical position of the foot pedal 43 to be adjusted according to the operator's needs. This improves the operator's posture, reduces physical discomfort from prolonged work, and increases work efficiency and operational comfort. Therefore, throughout the process, the sealing mechanism 3, foot pedal mechanism 4, and lifting and adjusting mechanism 5 work together to achieve not only efficient and precise sealing operations but also significantly improve the ergonomics and applicability of the equipment. This solves the problems of inconvenient operation and limited adjustment functions inherent in traditional foot-operated sealing machines. The lifting and adjusting mechanism 5 includes a horizontal frame 51, a U-shaped frame 52, a lifting plate 53, and a cylinder 54. The horizontal frame 51 is horizontally welded and fixed to... Between the bottom ends of bracket 2, a U-shaped frame 52 is welded and fixed to the middle of the top of the cross frame 51. A lifting plate 53 is movably disposed inside the U-shaped frame 52. The rear end of the connecting plate 42 is movably connected to the front end of the lifting plate 53 via a rotating shaft. A cylinder 54 is bolted to the inside of the bottom end of the U-shaped frame 52, and its output end is fixedly connected to the bottom of the lifting plate 53. This cylinder 54, through its output end, pushes the lifting plate 53 to move up and down inside the U-shaped frame 52, thereby driving the connecting plate 42 and the foot pedal 41 to move up and down, ultimately achieving height adjustment of the foot pedal 43. This allows the height of the foot pedal 43 to be flexibly adjusted according to the needs of different operators, improving the operator's working posture, reducing fatigue from prolonged operation, and improving operational comfort and work efficiency.Both sides of the top of the lifting plate 53 are welded and fixed with vertically distributed guide posts 55, and both sides of the top of the U-shaped frame 52 are provided with guide holes corresponding to the guide posts 55. With this structure, when the cylinder 54 pushes the lifting plate 53 up and down inside the U-shaped frame 52, the guide posts 55 slide along the guide holes at the top of the U-shaped frame 52, ensuring that the movement trajectory of the lifting plate 53 always remains vertical, avoiding instability caused by tilting or offset. Both sides of the bottom of the lifting plate 53 are provided with support springs 44, and the top of the support springs 44 is fixedly connected to the bottom of the connecting plate 42. With this structure, when the operator steps on the foot pedal 43, the foot pedal 43 transmits force to the support springs 44 through the connecting plate 42. The support springs 44 are compressed, providing additional support force, ensuring that the foot pedal 43 is more stable and reliable during stepping. Furthermore, when the operator releases the foot pedal 43, the support springs 44 and the return spring 6 work together to quickly reset the foot pedal 41 and the connecting plate 42, preparing for the next operation. This not only improves stability but also... The improved stability and response speed of the foot pedal 43 during pedaling effectively reduce operator fatigue during frequent operation. The bottom of the return spring 6 is equipped with a limiting ring 61 sleeved around the foot pedal 41. Vertical shafts 62 are screwed to both sides of the bottom of the foot pedal 41 where it connects to the control panel 1. Guide sleeves sleeved around the vertical shafts 62 are welded to both sides of the limiting ring 61. An arc-shaped block 63 is connected to the bottom end of the vertical shaft 62, and the front end of the arc-shaped block 63 is inserted through a threaded sleeve. An adjusting stud 64 is provided, with a pressing block 65 at its top. A pressing hole matching the structure of the pressing block 65 is provided at the bottom of the front end of the limiting ring 61. The adjusting stud 64 rotates within the threaded sleeve at the front end of the arc-shaped block 63, causing the pressing block 65 to contact the pressing hole at the bottom of the front end of the limiting ring 61. When the limiting ring 61 is under force, it moves vertically with the assistance of the vertical shaft 62, thereby controlling the initial compression degree of the adjusting return spring 6 and achieving precise control of the return force.
[0019] Working Principle: When using this convenient sealing bag making equipment for food packaging composite film bags, the operator first adjusts the initial compression of the return spring 6 according to their needs by adjusting the stud 64. During the adjustment process, the stud 64 is first rotated within the screw sleeve at the front end of the arc block 63 until the stud 64 drives the pressure block 65 to contact the pressure hole at the bottom front end of the limiting ring 61. When the limiting ring 61 is under force, it moves vertically with the cooperation of the vertical shaft 62. When the limiting ring 61 moves vertically, it slides outside the vertical shaft 62 through the guide sleeve until the return spring 6 is controlled and adjusted to a suitable restoring force. Then, the operator steps on the foot pedal 43 of the foot pedal mechanism 4. The foot pedal 43 is linked to the bottom end of the foot pedal rod 41 through the connecting plate 42. The foot pedal rod 41 moves downward, driving the lower pressure arm 32 to descend. The heating plate 33 on the lower pressure arm 32 contacts the edge of the composite film bag that needs to be sealed. The edge sealing operation is completed by heating and pressurizing. The control panel 31 is used to set and monitor edge sealing parameters, such as temperature and pressure, to ensure precise control of the edge sealing process. After the edge sealing is completed, the operator releases the foot pedal 43. At the same time, the support spring 44 is compressed to provide additional support force, and the return spring 6 also provides restoring force to help the foot pedal 41 and its connected components quickly return to their original positions, preparing for the next edge sealing operation. If the height of the foot pedal 43 needs to be adjusted, the lifting plate 53 can be pushed up and down inside the U-shaped frame 52 by the cylinder 54 in the lifting adjustment mechanism 5. When the lifting plate 53 rises and falls, it drives the guide post 55 to slide along the guide hole at the top of the U-shaped frame 52. At the same time, the lifting plate 53 drives the foot pedal 41 and the foot pedal 43 to move up and down through the connecting plate 42, thus realizing the adjustment of the height of the foot pedal 43 and completing a series of operations.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
