[Prior art]

 At present, tube packaging containers are available in a variety of products depending on the design of the outer surface and printed patterns, and must be applied to the packaging of creamy products such as cosmetics, foods, medicines and cleaning supplies, and must be used as packaging containers. Although the demand for tubing is high, many processing steps can be applied in the manufacture of tubing, but tubing is based on extrusion and cutting. It is manufactured by sending a long extruded cylindrical body to a cutting machine using a conveyor and cutting it. After injection, it is cut to the required length in an integrated operation. However, the cutter structure of the conventional cutting machine was advanced by a cutter that cuts flat, the cutting operation was slow, and it was easy for cutting defects and cut parts to be uneven. In addition, the speed of the tube extruding end must be set slowly in accordance with the cutting speed of the cutting device, resulting in poor tube production efficiency. For this reason, there has been a demand for a cutter device for a tube extrusion cutting machine capable of efficiently cutting a tube and increasing the production amount of the tube.
