Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spandex thread testing technology, in particular to a spandex thread adhesion testing device and method in a thread cake. BACKGROUND

[0002] In the production and application of spandex threads, the threads are usually wound into thread cakes, and are generally wound on the surface of a paper tube for storage, transportation and subsequent processing. The adhesion of the threads in the thread cake is crucial to the product quality and processing performance. When the threads are wound on the paper tube to form a thread cake, the adhesion of the threads in the thread cake directly affects the stability of the thread cake during storage. If the adhesion is too low, the threads are prone to loosen, which may cause the thread cake to deform and the threads to become disordered. This not only affects the convenience of storage, but also may cause more damage during subsequent handling and transportation. At the same time, loose threads are also more susceptible to external factors such as dust and moisture, which reduces the quality of the threads.

[0003] Referring to Chinese patent CN117147428A, a spandex unwinding testing device and method, which comprises an unwinding mechanism, a guide mechanism and a traction mechanism. The unwinding power of the present application comes from the tangential force of the first and second unwinding rollers, and the outer circumference of the thread cake is tangent to the first and second unwinding rollers. During the unwinding process, the threads are unwound from the thread cake at the tangent plane of the unwinding rollers, so that the length and tension between the tangent plane of the unwinding rollers and the traction roller remain unchanged, thereby ensuring the stability of the unwinding test. The present application sets a compression roller on the traction roller, and the threads are drawn through the traction roller and the compression roller, which increases the static friction between the traction roller and the threads, improves the traction ability of the traction roller to the threads, and through the compression roller, increases the retention of the threads in the gap, improves the stability of the traction, so as to realize high traction ratio unwinding test.

[0004] Compared with the patent CN117147428A, although the spandex unwinding testing device and method can test the unwinding performance of the threads in the thread cake and observe the adhesion of the threads during the unwinding process, there are still some problems. The unwinding test can only simulate limited actual working conditions, and cannot fully simulate the transportation and storage environment and reflect the influence of external forces. During transportation, the thread cake wound on the paper tube will inevitably be subjected to external forces such as vibration and impact.
