Description

Technical Field

[0001] The invention relates to the technical field of cotton fiber detection, in particular to a performance detection device for cotton fiber materials. Background Art

[0002] Cotton fiber material, also known as cotton, is a natural cellulose fiber mainly formed by cottonseed epidermal cells. It is favored for its excellent performance characteristics and is widely used in the textile field. In the packaging field, cotton fiber material can be produced into environmentally friendly and practical packaging bags. These cotton packaging bags have become an important choice for modern green packaging with their natural and degradable characteristics. After processing, the performance of the packaging bags is usually tested, but the existing testing devices still have certain deficiencies when used.

[0003] For example, the BC / cotton fiber material breaking strength testing machine for food packaging with publication number CN115931540A, which passes the two ends of the cotton fiber packaging bag through the first clamping plate and the clamping groove, the motor drives the second C-shaped rod to descend through the first threaded rod and the threaded block, the second C-shaped rod squeezes the first clamping plate through the first lower pressing plate and the lower pressing block, the first clamping plate drives the clamping block and the clamping block in the clamping groove to squeeze and fix the cotton fiber packaging bag, at the same time, the threaded block drives the first lower pressing plate to squeeze the first clamping plate through the second lower pressing plate and the fixed plate and the first C-shaped rod, the cotton fiber packaging bag is fixed and clamped, and the cotton fiber packaging bag is not easily broken from the fixed position through the bite of the clamping block. Slippage in a fixed component will not affect the test results. However, during the test, only a single stretching direction is used, so the equipment must reserve enough space to meet the stretching requirements. This design inevitably leads to a significant increase in the overall volume of the equipment, which may affect the portability, installation cost and space utilization efficiency of the equipment. At the same time, when different areas need to be tested, the position of the cotton fiber material needs to be changed frequently, so the test efficiency is low. In addition, due to the thin thickness of the cotton fiber material and frequent replacement, the staff are tired of work, and there is a problem of cotton fiber material falling off, which affects normal testing.

[0004] Therefore, we propose a performance testing device for cotton fiber materials to solve the above-mentioned problems. Summary of the invention

The servo motor 3 is further started, and the servo motor 3 will drive the tearing mechanism to move to both sides, so as to perform strength testing on the cotton fiber material. The detection results can be monitored and recorded in real time through the setting of the detection platform 2. After the detection is completed, the cotton fiber material can be removed.

[0033] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above embodiment 1. The existing cotton fiber material is thin and frequently replaced, which makes the staff tired of work and causes the cotton fiber material to fall off, thus affecting the normal detection.
