The stopper 4 is in contact with the driving end surface of the piston rod 22 to ensure the accuracy of the amount of dripping water.

In another embodiment, as shown in fig. 3, the drip member positioning seat 3 and the stopper 4 are each provided with a horizontal opening for accommodating translational loading and unloading of the injection drip member 2. In the figure, the limiting member 4 includes an annular arc-shaped limiting portion, the horizontal opening width of the annular arc-shaped limiting portion is larger than the diameter of the outer contour of the piston rod 22, and the diameter of the central hole of the annular arc-shaped limiting portion is smaller than the diameter of the end face of the driving end of the piston rod 22.

In another embodiment, as shown in fig. 5, the sample sites 73 are provided with one-to-one indicators having two indicating states that are switchable.

Drip spread test: the switching mechanism 8 drives the rotating disc 72 to rotate around the central rotating shaft, and the sample is transferred to the lower part of the injection dripping piece 2; when the limiting part moves downwards to a preset height, the piston part of the air cylinder of the telescopic part 6 extends out to push the driving end of the piston rod 22 to move downwards until the driving end of the piston rod 22 abuts against the limiting part, and the piston part of the air cylinder of the telescopic part 6 retracts into the cylinder body; the water drops fall on the surface of the textile sample for diffusion, and the image acquisition device 1 acquires and stores the water drop diffusion image on the surface of the textile. The above operation is repeated to realize the water droplet diffusion test for the next sample in the rotary disk 72.

In the actual automatic test, the test time of a single sample can be set to be a fixed length, or the diffusion end point of the water drop can be judged by photographing and comparing, so that the diffusion end point can be used for determining the time point for switching the next sample to the position below the water dropping opening.
