[0002] A soft towel is a dry wiping towel made of textile fibers through non-woven process for cleaning human skin. The wiping cleanliness of a soft towel refers to the ability to clean stains when using the soft towel for wiping. With the continuous improvement of living standards and hygiene requirements, people have an increasing need to use soft towels for skin wiping, and the testing methods for this performance also need to be increasingly improved. Currently, there is a lack of a detection device for the wiping cleanliness of soft towels, and there is also a lack of a method for detecting the wiping cleanliness of soft towels. Content of the Utility Model

[0003] To solve the deficiencies of the prior art, the utility model provides a detection device for the wiping cleanliness of soft towel stains.

[0004] The technical solution provided by the utility model is as follows:

[0005] A detection device for the wiping cleanliness of soft towel stains, comprising:

[0006] A specimen holder having a horizontal upper end surface for placing a test sheet;

[0007] A driving mechanism drivingly connected to the specimen holder for driving the specimen holder to move linearly;

[0009] A pressing mechanism for fixing the soft towel and pressing the soft towel against the surface of the test sheet;

[0010] And an obstructive structure for preventing the pressing mechanism from moving along with the specimen holder.

[0011] Based on the above technical solution, a test sheet with stains, such as an artificial skin membrane or a membrane of other materials, can be fixed on the specimen holder, and then during the movement of the specimen holder, the soft towel is used to wipe the stains on the test sheet, so as to obtain a soft towel wiped with stains. In this way, the weight of the soft towel wiped with stains and the weight of the original soft towel can be obtained, and further, it can be used to determine the wiping and cleaning ability of the soft towel.

[0012] Specifically, the specimen holder is a horizontally arranged plate-like structure, which is arranged on a base and has a horizontal and smooth upper end surface.

[0013] Specifically:

[0014] The driving mechanism is a linear module, whose moving end is fixedly connected to the specimen seat, and whose fixed end is fixedly connected to the base;

[0025] Based on the above technical solution, the sponge pad at the lower end of the slider increases the friction force, and in cooperation with the wire rope, it can avoid moving along with the movement of the specimen seat. Moreover, the clamping structure is convenient to install and disassemble.

[0026] Specifically:

[0027] Two grooves are arranged around the opposite two peripheral walls of the slider;

[0028] Two opposite edges of the soft towel are clamped in the two grooves through a clamping frame.

[0029] Based on the above technical solution, it is convenient to fix the entire soft towel by clamping the edge of the soft towel in the groove, thereby preventing it from sliding as the specimen holder moves.

[0030] Specifically, the clamping frame includes a square shape formed by two pipe strips and two springs. Moreover, the two pipe strips are arranged in parallel, and the two springs are arranged in parallel.

[0031] Based on the above technical solution, by pulling apart the pipe strips, the opening of the clamping frame can be widened, making it convenient to put it on the groove of the slider. Also, the operation of putting it on the groove of the slider and the operation of removing it from the slider are both convenient.

[0032] Furthermore:

[0033] A fixing post is provided on the upper end surface of the slider;

[0034] A fixing platform is provided at one end of the base away from the specimen holder;
