A method for folding and laying a bed sheet device for automatic medical use, the specific steps include:

S1: Pull down the pull plate 17, drive the splint 15 to slide down through the slide bar 16, then align the bracket 7 with the edge of the bed plate 5, release the pull plate 17 at this time, and press the bed plate 5 tightly under the elastic force of the tension spring 14 , to achieve effective fixation of the bracket 7, and at the same time, this setting can meet the fixed use of nursing beds with different bed edge thicknesses, and has good versatility;

S2: When laying the bed sheet, the four corners of the bed sheet are clamped by the electromagnets 18 and the corresponding iron blocks 19 respectively. When clamping the four corners of the bed sheet, the vertical plate 11 can be turned over by the short shaft 10, so that it is first turned to a horizontal posture, Then, the short shaft 10 slides on the inner wall of the strip groove 12 to minimize the distance between the electromagnets 18 disposed on the vertical plates 11 at both ends of the bed board 5 and the corresponding iron blocks 19, so that the sheets can be kept loose when clamping the sheets. It is in this state, which is convenient for medical staff to operate and improve its clamping efficiency. The specific operation is to pull the pull ring 20 outwards by hand and release it again. Under the action of the attraction of the opposite sex magnet, the bed sheet can be effectively clamped, and then the vertical The board 11 is turned over and returned to the vertical state, and the vertical board 11 is slid down through the short shaft 10 along the strip groove 12, so that the edge of the bed sheet can be passed down along the gap between the mattress 6 and the bed board 5. To the bottom of the bed board 5, the threshold value of the tension sensor is set in advance. When the bed sheet is inserted into the bottom of the bed board 5, the medical staff continues to apply downward pressure. When the electromagnet 18 is pulled upward, the tension sensor detects that it exceeds the set value. The force of a certain threshold value and the duration exceeds two seconds, the electromagnet 18 is automatically disconnected, so that the electromagnet 18 and the corresponding iron block 19 loosen the bed sheet, so as to avoid tearing the bed sheet and cause the deformation of the bed sheet, and save the time of removing the bed sheet. The operation steps can improve the spreading efficiency of the sheets, and the sheets are fixed after being spread through the bra-shaped buckles arranged at the four corners of the sheets. This method makes the fixed sheets more reliable and convenient, and completely solves the problem of manual tucking in the process. The trouble of sheets saves the time of medical staff;

S3: After the bed sheet is laid, the pull-down plate 17 drives the splint 15 to slide down, releasing the clamping of the bed plate 5, so that the bracket 7 can be removed. When the bed sheet needs to be replaced after a period of use, the bracket 7 is again fixed on the The edge position of the bed board 5, then insert the vertical plate 11 into the bottom of the bed board 5, release the buckle used to fix the bed sheet, and then clamp the corner of the bed sheet in the inner wall of the electromagnet 18 and the corresponding iron block 19, and the vertical plate 11 Pull back through the pull hole 13, turn the vertical plate 11 to the horizontal position again, release the clamping of the sheet by the electromagnet 18 and the corresponding iron block 19, pass one end of the sheet through the clamping roller 21, and the winding mechanism passes through the bottom plate 1 and the universal wheel set at the bottom of it is pushed to the tail position of the bed board 5. At this time, the narrow side of the bed sheet is rolled into the rotating shaft 40 by turning the flip cover 39 through the handle 32. The outer wall of the rotating shaft 40 is provided with evenly distributed rubber bumps, so that the bed sheet can be reliably is attached to its outer wall, at this time, closing the flip cover 39 makes the arc plate 36 press against the rotating shaft 40 under the action of the thin spring to prevent the sheet from falling off;

S4: The height of the pinch roller 21 can be adjusted up and down arbitrarily through the vertical plate 11. At this time, the dust suction mechanism and the motor 25 are activated. The motor 25 drives the second flywheel 29 and the rotating shaft 40 to rotate by driving the first flywheel 27 and the transmission of the belt 28. To realize the rewinding of the sheets, the disinfection lamp 35 activated during the rewinding process physically sterilizes the sheets to prevent the breeding of bacteria and viruses, and the brushes 37 are set to stagger two different lengths, and the brushes 37 of different lengths are staggered. The setting can effectively peel off the hair, skin debris, etc. adhered to the outer wall of the sheet. At this time, under the action of the air pump 26, these sundries are drawn into the dust box 38 for collection. The distance between the guiding action and the clamping roller 21 is smaller than the width of the bed sheet, which causes the bed sheet to be pulled into a concave shape, and the base plate 9 is vibrated by the arc spring 8, which can remove the hair and debris on the bed sheet. Wait until it is effectively shaken on the center of the bed sheet, at this time, it is convenient for the vacuuming mechanism to effectively collect these sundries. After the bed sheet is rolled up, unscrew the box cover 33 and take out the rolled bed sheet.
