Therefore, the packaging film must be detected in real time during the production process to find the defective packaging film. However, manual detection is time-consuming and labor-intensive, and there is a possibility of missed detection. By adding a mounting plate, a heat dissipation air inlet, an air inlet filter, a fan mounting frame, a heat dissipation fan, an air outlet and an air outlet filter, the problem that dust and heat are high during long-term use and easily lead to untimely response of the sensor, thereby leading to missed detection is solved.
