Through the precise control of servo motors and multi-stage transmission systems (such as optical axes, gears, guide rails, etc.), each mechanism can achieve precise positioning and operation. The arm push mechanism can accurately push the items onto the working platform, and the knife sealing mechanism can accurately align the packaging bag for sealing, ensuring the reliability and consistency of packaging. By integrating a dual-film system and an automatic switching mechanism, the baler can automatically switch from one film roll to another without interrupting the production process to adapt to bottles of different sizes. This significantly reduces the downtime caused by film change, improves the overall production efficiency, and enables the production line to perform packaging operations continuously.

[0019] 2. The various mechanisms work together through precise servo motors and control systems, which reduces the need for manual intervention and reduces production failures caused by human operational errors. This not only improves the stability and reliability of the production line, but also improves the overall level of automation.

[0020] 3. The modular design of the equipment makes each mechanism relatively independent and easy to disassemble and replace. When a mechanism fails, it can be repaired or replaced separately, reducing maintenance costs and downtime. BRIEF DESCRIPTION OF THE DRAWINGS
