Detection and sampling device for color fastness of inner sides of shoes

Abstract

The invention discloses a detection and sampling device for the color fastness of inner sides of shoes. The detection and sampling device comprises an operation device for sampling the inner part of a testing object and a controller for controlling the operation device, wherein the operation device comprises a clamp; the clamp comprises an upper clamp and a lower clamp which are connected together through a connection assembly; the connection assembly comprises a main shaft; the main shaft is provided with an upper clamp connection shaft which is used for fixing the upper clamp and can rotate relative to the main shaft; the lower clamp is fixed on the main shaft; a motor storing groove is formed in one end of the main shaft; a motor is arranged in the motor storing groove; the output end of the motor is connected with a felt through a motor transmission shaft; the motor is connected with the controller; when the detection and sampling device is used, the felt is located on the inner side of the testing object and is tightly pressed by the lower clamp; and the upper clamp is located on the outer side of the testing object and is matched with the lower clamp to tightly clamp the testing surface of the testing object. The detection and sampling device provided by the invention can be suitable for almost shoes with different types and different sizes, and sampling can be carried out under the condition that an original structure of the shoes is not damaged.

Description

technical field [0001] The invention relates to a device for detecting performance parameters of footwear, in particular to a sampling device for detecting color fastness of the inner side of footwear. Background technique [0002] Color fastness, also known as color fastness and dyeing fastness, refers to the resistance of the color of textiles to various effects in the process of processing and use, such as sunlight, damp heat, water, washing, sweat, dry and wet rubbing, etc. On the one hand, it is a routine test item in the intrinsic quality test of textiles, and the fastness level is evaluated according to the discoloration of the sample and the staining of the undyed adjacent fabric. With the gradual improvement of people's living standards and the rapid development of science and technology, the detection of performance parameters such as the color and firmness of the inner side of footwear has become more and more important. Please refer to the national standard (GB / ...

Problems solved by technology

[0003] At present, the common sampling devices for testing the color fastness to rubbing of leather and textiles at home and abroad can be divided into linear friction sampling devices and rotary friction sampling devices according to different friction methods. However, due to the special structure of shoes, these two types of sampling devices None of the devices can ideally complete the sampling work for testing the color fastness to rubbing of shoes

First of all, the linear friction sampling device has strict requirements on the size of the test product. If the test product is larger than the required size, it needs to be cut. If the test product size is smaller than the required size, it cannot be sampled. Small-sized leather and textiles are tested, but due to the large difference in the linear speed of each point on the rotating plane, the sample will be stained unevenly during the sampling process, which will affect the objectivity of the test results
