Description

Technical Field

[0001] The present invention relates to the technical field of nylon detection, in particular to a nylon monofilament strength detection device. Background Art

[0002] Cotton is a modified polypropylene fiber. The super cotton underwear, bathrobes, T-shirts and other products developed and produced with it have relatively superior properties such as warmth retention, water absorption, moisture conduction, quick drying and antibacterial. It is a high-end fabric. The wicking effect of cotton fiber makes it have excellent properties such as gentle warmth retention, moisture conduction and dryness, hygiene and antibacterial. Polypropylene fiber has the advantages of low specific gravity, non-water absorption, low thermal conductivity, good chemical resistance and good hygiene. Due to the geometric characteristics, surface effect, gloss effect and mechanical properties after fine denier, the fiber has changed its original shortcomings such as poor feel, waxy feel and poor moisture absorption, and has a very soft feel, soft luster and excellent moisture absorption and sweat conduction.

[0003] In most existing nylon strength testing processes, an elliptical block is generally rotated up and down to reapply force to various parts of the entire nylon filament, thereby increasing the testing effect. At the same time, when the elliptical block is rotated to a certain angle, the nylon filament may deform and break away from the elliptical block. At this time, the nylon filament can be stuck in the groove of the push pin by moving the push pin, effectively avoiding the problem of the nylon filament breaking away from the groove of the elliptical block due to deformation.

[0004] The above method still has the following problems: although it prevents the nylon monofilament from being separated due to deformation and prevents the nylon monofilament from being separated from the groove and affecting the detection of the strength of the nylon monofilament, during the detection process of the nylon monofilament, it is necessary to control the temperature and humidity during the detection, so that the nylon monofilament needs to be balanced inside the constant temperature and humidity chamber to ensure the humidity and temperature of the nylon monofilament. However, in most existing technologies, the temperature and humidity balancing time of the nylon monofilament is relatively long, resulting in a long waiting time before the nylon monofilament strength detection, which reduces the efficiency of the nylon monofilament strength detection.

[0005] Therefore, the present invention provides a nylon monofilament strength detection device to solve the above problems. Summary of the Invention

Then, through the movement of the moving block, one end of the polyamide monofilament is driven to move, and the tensile force generated by it is detected based on the tensile force sensor. Moreover, through the mutual cooperation of the non-contact video extensometer and the yield point detection tangent method, the yield point of the polyamide monofilament is detected, so as to reflect the critical stress value when the polyamide monofilament transitions from the elastic deformation stage to the plastic deformation stage, and more intuitively reflect the tensile strength of the polyamide monofilament; Based on the settings of structures such as the adjustment mechanism, the temperature and humidity inside the detection box are monitored in real time according to the temperature and humidity sensor. In response to the changes in temperature and humidity, based on the mutual cooperation of components such as the electric heating plate and the circulation pipe, the temperature and humidity inside the detection box are adjusted to control the temperature and humidity inside the detection box within a certain range, avoiding the influence of the temperature and humidity inside the detection box on the detection of the yield point of the polyamide monofilament and causing errors in the calculation results of the yield point, so that the results of the polyamide monofilament strength detection are more accurate.
