中空成型机行业在成型过程中需要通过高温热切刀将连续的管状塑料坯体切割成段。热切刀是利用变压器将我们常用的交流电压变成较低电压加在可以导电的金属刀片两端构成回路形成电流，然后电流通过可以导电的金属刀片会产生热量；我们利用通电的金属刀片会发热的原理来对我们的型坯进行切割。但是我们的中空成型设备在连续运行的时候刀片处于高温状态材质会变软同时在刀片切割坯体的时候会受到力的作用时间长了切刀片就会断掉同时断掉的切刀片会因为重力作用下坠；这时如果切刀片断了我们没有检测刀片断掉的功能，机器还是会继续运行，等到下次合模的时候模具很有可能将断掉的切刀片夹住造成设备或模具损坏。The blow molding machine industry needs to cut the continuous tubular plastic body into segments by high temperature hot cutter during the molding process. The hot knife uses a transformer to change our commonly used AC voltage into a lower voltage and adds it to both ends of the conductive metal blade to form a circuit to form a current, and then the current passes through the conductive metal blade to generate heat; we use the energized metal blade to generate heat The principle to cut our parison. However, when our hollow molding equipment is in continuous operation, the blade is in a high temperature state, the material will become soft, and the blade will be subjected to force when it cuts the green body. After a long time, the cutting blade will break and the broken cutting blade will be due to gravity. At this time, if the cutting blade is broken, we do not have the function of detecting the broken blade, and the machine will continue to run. When the mold is closed next time, the mold is likely to clamp the broken cutting blade and cause equipment or mold damage.
