[0029] The specific implementation method is as follows: when using the present invention, after the bed sheets are washed and dried, the staff takes the bed sheets out of the washing and drying barrel and lays them on the guide roller 10, the squeezing roller 12 and the pushing roller 6, inserts one side of the bed sheets between the squeezing roller 12 and the pushing roller 6, and then presses the sterilization start button. At this time, the pushing motor 7 drives the pushing roller 6 to rotate, and at the same time, the squeezing hydraulic cylinder 17 pushes the limiting frame 15. The limiting frame 15 squeezes the square seat 14 through the squeezing spring 16, so that the squeezing roller 12 is close to the bed sheets and forms an extrusion discharge state with the pushing roller 6. In this process, the heating rod 9 will be started, and the pushing roller 6 can be quickly heated through the heat conducting plate 8, which can achieve the effect of drying, and cooperate with the extrusion discharge formed by the squeezing roller 12 and the pushing roller 6. The state of the material can achieve the effect of ironing and reduce the wrinkles of the sheets. In this process, the ultraviolet sterilization lamp 19 will also be started, and the sheets passing through the squeezing roller 12 and the pushing roller 6 will pass between the two ultraviolet sterilization lamps 19, so as to achieve comprehensive sterilization on the front and back sides. After all the passing, the sheets will fall into the storage box 20. At this time, the sterilization closing button 23 can be pressed. After the next sheet is laid out, it can be started again. This makes the present invention not only capable of washing and drying the sheets, but also capable of sterilizing and disinfecting the sheets, ironing to remove wrinkles, and assisting in heating and drying, so that the sheets are clean after processing and the problem of residual bacteria is avoided. At the same time, the drying speed of the sheets is also accelerated, which is convenient for the rapid reuse of the sheets, making the actual use effect of the present invention more ideal.
[0030] Working principle of the present invention: Refer to the instruction manual Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4When the present invention is used, by providing the push motor 7, the push roller 6, the ultraviolet sterilization lamp 19 and the extrusion hydraulic cylinder and other structures, the present invention can not only wash and dry the sheets, but also sterilize and disinfect the sheets, iron and remove wrinkles, and can also assist in heating and drying, so that the sheets are clean after treatment, avoiding the problem of residual bacteria, and also speeding up the drying speed of the sheets, which is convenient for the rapid reuse of the sheets, making the actual use effect of the present invention more ideal.
