AI Technical Summary
In the needle-punching production line, the loosening of the base fabric leads to wrinkles and stacking, affecting the uniformity of the stitches and the strength and stability of the base fabric.
A capacitive sensor is used to monitor the fabric tension. The height of the tension roller is adjusted by a control box and a motor-driven threaded rod. Combined with ball bearings to reduce friction, the tension of the conveyor roller is adaptively adjusted to ensure the fabric is conveyed smoothly.
It effectively eliminates wrinkles and stacking, ensures smooth needle punching, enhances the strength and stability of the base fabric, and extends the service life of the equipment.
