Sock stretching detection instrument

Abstract

The invention provides a sock stretching detection instrument, belongs to the technical field of tests, and solves the technical problems that a conventional sock stretching detection instrument is lower in detection data reference value and cannot achieve the purpose of detection. The sock stretching detection instrument comprises a machine frame, wherein a sliding rail, a fixed clamping head and a movable clamping head are arranged on the machine frame; the sliding rail is fixed to the machine frame; a sliding block is glidingly connected to the sliding rail; the movable clamping head is fixed to the sliding block; a fixed seat is fixed at one end of the sliding rail on the machine frame; the fixed clamping head is fixed to the fixed seat; a drive mechanism capable of driving the sliding block to slide along the sliding rail is fixed at the other end of the sliding rail on the machine frame. The sock stretching detection instrument has the advantages that a usage state of socks is closer to an actual usage state of the socks when the socks are stretched, so that the detection data is more accurate.

Description

technical field [0001] The invention belongs to the testing field, and relates to a sock, in particular to a sock tensile tester. Background technique [0002] The lateral extension value of socks is an important means to control the quality of socks. Its purpose is to measure the size of the extension performance of socks and reflect the quality of socks wearing performance. So what indicators are used to evaluate the wearing performance of socks and what methods are used to reflect these indicators have become a concern of people. So far, although the sock standard has been revised many times, there are still some deficiencies in order to comprehensively evaluate the wearing performance of socks. A single control of the lateral extension value cannot ensure that the socks have proper elasticity and are comfortable to wear. For example: socks are worn on a foot of a certain size, which can be considered as the vertical and horizontal loads under the condition of constant e...

Problems solved by technology

For example, the ribbed fabric with a tight structure within a certain range has a large yarn bend, so the elasticity is better. On the contrary, the knitted fabric with a sparse structure has a large loop length and a small yarn bend, so the degree of recovery after stretching will decrease accordingly. lower, less elastic

[0006] At present, the instruments for detecting the stretching of socks cannot satisfy the detection of stretching of socks. For example, the sock stretching instrument [CN201322707Y] disclosed in Chinese patent literature includes a detection mechanism, a transmission mechanism, an information processing mechanism, a control mechanism, and an output mechanism; The extensometer cannot fix the socks during the stretching test, and the socks will slip during stretching, resulting in inaccurate detection data; the socks are not in use when the stretcher is stretching the socks, so the detected data and The data in actual use will have a large gap, resulting in low reference value of the detection data and failing to achieve the purpose of detection
