Description

Technical Field

[0001] The utility model relates to the technical field of plastic plate bending, in particular to a bending device for producing plastic panel boxes. Background Art

[0002] A panel box is a foldable logistics turnover box, usually made of plastic or wood. The structure of the panel box includes a pallet (base), a box body and a cover, which are combined in a stacked manner. It is generally composed of four or six panels. These panels are equipped with side doors to facilitate the entry and exit of goods. They can be folded up when not in use to save space. The design of the panel box usually makes the length and width determined according to the size of the pallet, and the number of layers used can be determined according to the height of the load. This can maximize the utilization of the box space. Some plastic panel boxes require the use of corresponding plastic bending devices to heat and bend the bending parts of the plastic sheets during the production process.

[0003] For example, the application number is CN202223084974.1. The utility model relates to the technical field of bending machines, and proposes a bending machine for plastic plate production, including a workbench, a driving block is fixedly installed in the middle of the front side of the workbench, a folding plate is movably installed on the left side of the top of the workbench, a rotating shaft is fixedly installed on the right side of the folding plate, and a base plate is fixedly installed on the right side of the rotating shaft. The bending machine for plastic plate production is used in conjunction with a heating block structure and an extrusion block structure.
