Description

The present invention belongs to the field of packing machine technology, and specifically relates to an automatic styrofoam filling device for corrugated cardboard packing.

In the packing field, corrugated cardboard packing is the most widely used packing method. Process the cardboard box to the appropriate size and structure, depending on the product to be packed. Some products can be packed directly in cardboard boxes, but for products that are fragile or cannot withstand impact, airbags are placed in cardboard boxes or styrofoam for cushioning and fixation. Often fills vacant spaces on cardboard. The conventional styrofoam filling operation for a cardboard box basically relies on manual work, that is, the styrofoam is manually put into the cardboard box. Since the purpose of filling Styrofoam is to protect the product, the pretreated Styrofoam basically fits the corresponding cardboard box size. This causes inconvenience for the manual styrofoam filling operation. Therefore, in the conventional manual styrofoam filling work, the operation is inconvenient, the packing efficiency is poor, and it takes time and effort.

The present invention has been designed to solve the above problems.
