Automatic cleaning method and cleaning bed for patient of gatism

An automatic cleaning method for a patient of gatism, comprising:

• starting a lifting mechanism to drive a first belt pulley to rotate so that a flat belt rotates to drive a connecting plate and a soft cushion platform to move downward to a first predetermined position, when an urine separation pad on a soft cushion is contaminated and needs to be replaced, ejecting, by a flushing device under a moving plate, clean water to wash an excreting part of the patient;
• starting a drying device to dry the excreting part washed after the washing is finished;
• and taking out the urine separation pad on the soft cushion which is contaminated;
• installing a roll-shaped urine separation pad material on a material roller under a bed body, clamping one end of the urine separation pad material between a first pressing roller and a second pressing roller;
• starting a double-shaft cylinder to drive a clamping mechanism to move toward a side of the urine specification pad material, and extending a lifting cylinder to reach a second predetermined position;
• operating the clamping mechanism such that a clamping motor is started to drive a rotary rod to rotate, so as to move a matching block to a side away from the material roller, which in turn drives clamping claws to move toward each other to clamp and move the urine separation pad material to the side away from the material roller until a new urine separation pad covers the soft cushion;
• starting a cutting motor of a cutting mechanism to rotate a screw, so as to move a reciprocating block along a path of a spiral groove of the screw;
• wherein the reciprocating block is moved only in a lateral direction due to being limited by a sleeve, so as to realize a cutting of the urine separation pad material by a blade, and the new urine separation pad cut is finally laid flat on the soft cushion;
• re-starting the lifting mechanism, resetting the soft cushion covered with the new urine separation pad, and finishing cleaning.
