[0002] A hot cutting machine generally refers to a device used for cutting materials (such as plastics, textiles, films, etc.) in industrial production. It uses high temperature to melt the materials and quickly cuts them through a cutter or a hot wire to achieve the cutting purpose. During the operation of this device, heat, dust, and harmful gases generated by the cutting materials will be produced. Therefore, corresponding safety and environmental protection measures need to be equipped. The hot cutting protection device for a hot cutting machine is an auxiliary device designed to protect operators from the heat radiation, dust, and harmful gases generated during the cutting process.

[0003] The existing hot cutting protection device for a hot cutting machine sucks away the waste gas generated during the operation of the hot cutting machine through a fan and purifies and discharges it through a purification plate to avoid the risk to health caused by personnel inhaling the waste gas, thereby realizing the protection function. However, the position of the suction pipe used to suck away the waste gas is fixed and cannot flexibly adjust the suction angle to suck away and purify the waste gas at different positions. When the working table surface of the hot cutting machine needs to be adjusted or different-shaped textiles are processed, it cannot effectively cover all positions where the waste gas is generated, resulting in some waste gas not being sucked away in time and overflowing outside the housing, reducing the protection performance of the protection device. Content of the Utility Model
