Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of washing equipment, and in particular to a linen pressure dewatering machine linen feeding automatic monitoring control mechanism. BACKGROUND

[0002] The linen pressure dewatering machine is a professional equipment commonly used in hotels, hospitals, laundry factories and other places to dewater linen (such as bed sheets, quilt covers, towels and other types of fabrics). It mainly uses centrifugal force or extrusion principle to realize the dewatering function. The wet linen is placed in a specially designed drum. When the equipment is started, the drum will rotate at high speed. The water in the linen will be thrown out through the drainage holes on the drum under the action of strong centrifugal force, so as to reduce the water content of the linen and make it dry quickly.

[0003] Through retrieval, the linen pressure dewatering machine linen feeding automatic monitoring control mechanism disclosed in Chinese patent application No. CN201120288188.6 includes a dewatering basket, a main machine control device, a dewatering basket left sealing door, a dewatering basket right sealing door, and a dewatering basket lower sealing door. The lower sealing door of the dewatering basket is connected to the lower end of the dewatering basket by a combined pin. The left and right sealing doors of the dewatering basket have holes on the outer sides. A grating sensor is installed at the corresponding position of the holes. The grating sensor is connected to the main machine control device. A gas cylinder is installed on the outer side of the lower part of the connection between the dewatering basket lower sealing door and the dewatering basket. The piston rod of the gas cylinder is installed on the outer side of the dewatering basket lower sealing door. The gas cylinder is connected to a gas compression device. An electromagnetic valve is installed on the pipeline connecting the gas cylinder and the gas compression device. The utility model ensures that the linen hung on the dewatering basket lower sealing door completely enters the dewatering basket, thereby avoiding the breakage of the linen pressure dewatering machine pressure air bag due to uneven stress.

[0004] In view of the above related technology, the inventors have found that the above prior art can detect the flowing linen by the grating sensor. When blocked, the linen hung on the dewatering basket lower sealing door is sent into the dewatering basket by shaking the dewatering basket lower sealing door up and down. However, in actual use, since the linen to be conveyed is not dewatered, there may be a lot of water on the outer side of the linen. When the water contacts the detection end of the grating sensor, it will stay a certain amount of water on the detection end of the grating sensor. Since the refractive index of water and the outer layer material of the optical fiber is different, it will change the optical environment of the light transmission in the optical fiber, such as causing light scattering, increased absorption and other conditions, thereby interfering with the normal grating reflection spectrum signal, and further affecting the accurate measurement of subsequent linen detection.
