The overall packaging of boxed butter employs advanced techniques to guarantee the superior quality and safety of the product. Initially, the PE bag is precisely inserted into the box by a bag inserting machine, offering the first layer of protection for the butter. Next, the automatic filling process commences, accurately filling the butter into the box. The filling quantity is strictly regulated to ensure that the weight of butter in each box is consistent. Subsequently, the automatic sealing machine seals the box opening, effectively preventing the butter from leaking and external impurities from getting inside. Following this is the manual capping stage. Workers manually tighten the box cover, which not only ensures a tight seal but also facilitates subsequent inspection and operation. After that, the product enters the metal detection phase. A metal detector is utilized to check if there are any metal impurities in the box, safeguarding the safety of the product. Finally, the weighing machine weighs the packaged boxed butter. Any product with an unqualified weight is removed, ensuring that each box of butter meets the established quality standards. This comprehensive packaging process not only enhances production efficiency but also secures the quality and safety of boxed butter, presenting consumers with a reliable product.
