Description
Technical Field
[0001] The utility model relates to the field of cutting devices, in particular to a foam plastic cutting device. Background Art
[0002] Foam plastic, also known as expanded plastic, is a lightweight, porous material made of plastic resin. Its unique feature is that it has a large number of tiny pores, which give it significant advantages in terms of low mass, heat insulation, sound insulation and cushioning performance. The characteristics of foam plastic include lightness, low cost, easy processing and excellent insulation performance. Therefore, foam plastic is widely used in various fields such as packaging, construction, transportation, manufacturing, etc.
[0003] In current manufacturing, thermal cutting is often used to cut foam plastics by heating the tool. By heating the tool to a temperature above the melting point and below the ignition point of the foam plastics, a smooth cut can be produced to avoid rough cut edges. However, due to the large thickness of the tool, it is easy to melt more foam plastics, which may lead to large errors in the cut part, resulting in the cut foam size not meeting the requirements. In addition, after the heat of the tool is lost, the tool surface is easy to adhere to the melted and re-solidified foam plastics, which requires further improvement and optimization.
