The description "图中为料盘下料形式" means "the picture shows the form of material tray discharging".
Regarding the question "若是液体包装可以改为自流??灌装或定量灌装", it means "if it is liquid packaging, can it be changed to self-flowing?? Filling or quantitative filling".
Hope this helps! Let me know if you have any other questions.
