It is to be understood that the height and angle of the water jet device are adjustable in the present invention, so that the jet area of the water jet device is variable.
The initial adjustment module of the setting state of the water jet device is configured to use the spun-laced nonwoven fabric transferred to the water jet area as a target object, where placement of the target object on the water jet area is shown in fig. 2, and obtain a size of the target object, and then perform initial adjustment on the setting state of the water jet device according to the size of the target object, where the setting state includes a setting height and a setting angle.
In a specific embodiment of the foregoing aspect, the adjusting the setting height in the initial adjustment of the setting state of the water jet device according to the size of the target object specifically includes the following steps: acquiring the length of the water jet region, comparing the length with the length of the target object, and using the expressionAnd calculating the length proximity of the target object and the water jet area, wherein e is expressed as a natural constant, and the smaller the length difference between the target object and the length of the water jet area is, the larger the length proximity is.
