荷兰采购需求：谷物填充包装机，自动填充包装机，定量大米包装机

I'm looking for a gravity feeding automatic bag packing machine that features a robust bag-holding rubber system. I also need it to have load cell technology for accurate weight measurements and pneumatic actuators to ensure smooth operation. Please provide detailed information about the specifications of the machine, including any options available that enhance its functionality. In addition, I would appreciate it if you could send me a comprehensive materials list related to the components and parts needed for this machine. Understanding the materials involved will help me assess compatibility with our current production setup. If you have any recommendations for additional features or upgrades, I'm open to discussing those as well. Looking forward to your detailed response!
