the method comprises the following steps: sleeving a bag box filled with a breakpoint-free garbage bag on a barrel from the upper part of a handle, pulling a part of a bag body out of the bag box by hands, sleeving the bag body outside two shovels, then controlling an opening and closing mechanism to separate the two shovels, then turning a part of the bag body inwards, inserting the part of the bag body into a space between the two shovels from the lower part of the shovels, then controlling the opening and closing mechanism to draw the two shovels together, enabling a shovel bottom plate to extrude the bag body, then enabling a folding mechanism to work, folding the bag body extruded by the bottom plate towards the middle by an extruding part to form a folding part, then pulling the bag body upwards for 1-2cm, then working a sealing mechanism, carrying out welding and sealing on the bag body which is approximately 1cm long below the folding part to form a welding part, separating the welding part, then pulling up the mechanical arm to move downwards, then clamping the welding part by the mechanical arm, at the moment, separating the two shovels by the opening and closing mechanism, then pulling up the mechanical arm and the welding part upwards by the pulling up mechanism, thus, a part of the bag bodies are further pulled out of the bag box, and more bag bodies are arranged between the shovels; covering the bag body between the two shovels on the excrement, controlling the shovels to approach by the opening and closing mechanism, shoveling the excrement into the bag body between the shovels, extruding the bag body by a bottom plate of the shovel, then working the folding mechanism, folding the bag body extruded by the shovel body to form a folding part, pulling the bag body upwards for 1-2cm, then working the sealing mechanism, welding the folding part by an electric soldering iron to form a welding part with the length of about 1cm in the vertical direction, fusing the welding part by a fusing wire, separating the two fusing parts, opening the door body to take out the bag body filled with the excrement, then working the pulling mechanism, clamping the fusing part b by a manipulator, lifting the pulling mechanism to pull out a part of the bag body from the bag box, and pulling a part of the bag body into the shovels for next use.
