Description

Technical Field

[0001] The utility model belongs to the technical field of textile testing, and in particular relates to a textile washing and shrinkage cycle testing box. Background Art

[0002] The Textile Wash and Shrinkage Cycle Test Chamber is a specialized device used to evaluate the shrinkage of textiles during the washing process. With the rapid development of the textile industry, the quality requirements for textiles are becoming increasingly stringent, especially in terms of washability. Textiles undergo multiple washes in daily use, and their dimensional stability directly impacts the consumer experience and the market competitiveness of products. Therefore, the Textile Wash and Shrinkage Cycle Test Chamber has become an indispensable tool in textile R&D, production, and quality testing.

[0003] While traditional textile wash and shrinkage cycle test chambers meet basic testing requirements to a certain extent, they still have some significant drawbacks in practical applications: The traditional drum design often results in uneven water flow distribution within the drum, with strong water flow in some areas and weak water flow in others. This uneven water flow distribution affects the washing effect and leads to inaccurate test results. During the washing process, textiles tend to tangle together, forming clumps, which affects shrinkage testing. After the test, poor drainage can cause a large amount of water to remain in the chamber, affecting the next test. During the washing process, textiles are subjected to excessive mechanical stress, resulting in damage or deformation. Utility Model Content

[0004] In view of this, the utility model provides a textile washing and shrinkage cycle test box, which solves the disadvantage of uneven distribution of water flow in the drum caused by the drum design of traditional test boxes. By designing a multi-step stepped drum, the phenomenon of local water flow being too strong or too weak is reduced.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a textile washing and shrinkage cycle test box, comprising a box body, wherein the box body is provided with a box door, wherein a stepped drum is provided inside the box body, the stepped drum is fixed at a central position inside the box body by a bearing, the axis of the stepped drum is parallel to the long axis of the box body, the two ends of the stepped drum are respectively close to the front and back sides of the box body, the stepped drum includes a plurality of step segments, the cross section of each step segment is circular, and the height and diameter of each step segment are different, the box body is provided with a driving device, a water supply mechanism and a drainage mechanism, the driving device is used to drive the stepped drum to rotate, the driving device is installed at one end of the box body, and a drainage hole is provided at the bottom of the box body.

[0007] The technical effects of the textile washing and shrinkage cycle test box provided by the utility model are as follows: the utility model provides a textile washing and shrinkage testing device with a compact structure and complete functions through the combination of a multi-stage stepped drum, a drive device, a water supply system, a drainage system and a box body, which can simulate a variety of washing conditions and improve the diversity and accuracy of the test.

[0008] On the basis of the above technical solution, the textile washing and shrinkage cycle test box of the present invention can also be improved as follows:
