Description

Hoarding box hoarding creasing machine head

technical field

The utility model relates to a plastic turnover box manufacturing equipment, in particular to a machine head of a special crease processing machine for the coaming board of a coaming box, and the machine head is the main processing head part of the crease processing machine.

Background technique

In the process of wholesale and retail of goods, a kind of coaming box is often used. The so-called coaming box, the specific structure is shown in Figure 9, and is made up of a tray 1, a loam cake 2 and a coaming panel 3, and the coaming panel 3 forms four side walls between the tray 1 and the loam cake 2; The board 3 is made of a plastic hollow board surrounded by butt joints. The coaming board 3 is specifically composed of two parallel and opposite fixed board parts and two parallel and opposite folded board parts. The first crease 4; the middle part of the two folded plate parts is also provided with a second crease 5 arranged along the longitudinal direction. During transportation and storage of an empty box, the hoarding 3 can be folded and stored between the tray 1 and the upper cover 2, which is very convenient to use.

In the field of plastic turnover boxes, the creases of hollow boards are usually made by scoring lines, that is, a line is carved at the creases. This kind of manufacturing equipment and technology is widely used in thin-walled light hollow boards. There are many, but the engraved lines will greatly reduce the strength of the box body, and a major feature of the above-mentioned coaming box is the high load-bearing requirement, and the coaming panels are all made of thick three-layer composite hollow boards (see Figure 10). It can be said that the line method is not suitable for making creases. In addition, people will also think of pressing the creases by hot pressing, but the current hot-pressing crease equipment is developed for real plastic boards, and is used to process thick three-layer composite hollow boards such as coaming boxes , it is easy to damage the surface of the board, and the production quality is poor.
