[0002] The centrifugal dewatering machine is a washing equipment matched with the tunnel type industrial washing machine. The tunnel type industrial washing machine is a washing equipment which simultaneously washes dirty linen such as bed sheets, quilt covers, towels and all washable fabrics through continuous pre-washing, main washing and rinsing, and finally acid-base neutralization. When all washing procedures are completed, the tunnel type industrial washing machine automatically guides the washed linen into the centrifugal dewatering machine for dewatering. The centrifugal dewatering machine is one of the matched dewatering equipment.

After dewatering, the inner cylinder is rotated by 180° as a whole, and the dewatered linen is automatically tilted out of the dewatering machine to the conveying belt, and then conveyed to the subsequent drying machine or post-processing equipment. The centrifugal dewatering machine brake device is used to reduce the vibration amplitude of the centrifugal dewatering machine caused by uneven distribution of the linen in the centrifugal dewatering machine through intermittent braking of the brake device, so that the linen can be dewatered stably in the whole process.
