Embodiment 1

[0021] Embodiment 1, as attached figure 1 Shown:

[0022] The cotton swab fiber head pull-out force test method includes the following steps: the first step is to select 20 cotton swabs to be tested in the same batch to be tested; the second step is to clamp all the cotton swabs to be tested on the same level with a synchronous fixture. The fixture includes The clamping seat 5 and the clamping seat 5 are fixed with a plurality of clamping parts of the same horizontal line. The clamping parts include a support plate 6 and a support hole 7. The support plate 6 bolts 8 are connected to the clamping seat 5, and the support plate 6 and the clamping seat 5 are provided with a gap for the cotton swab to pass through, the support hole 7 runs through the support plate 6 longitudinally, and the aperture of the support hole 7 is larger than the diameter of the cotton swab to be tested by 0.2mm; When the cotton swab comes out of the fiber head to the cotton swab to be tested, record the ...

Embodiment 2

[0042] Different from Example 1, after the first step selects a plurality of cotton swabs to be tested, the cotton swab of the cotton swab to be tested is shortened from the end away from the fiber head, and the length of the shortened cotton swab is the original length of the cotton swab. one-half of. In this way, the cotton swab can be shortened to reduce the increase of the contact area between the cotton swab and the support hole due to the curvature of the cotton swab itself, resulting in an increase in friction. At the same time, it can be ensured as much as possible that the cotton swab and the tension clamping head are on the same vertical line to ensure the effectiveness of the tension.

Embodiment 3

[0043] Embodiment 3, as attached figure 2 Shown:

[0044] The difference from Example 1 is that in the first step, the ratio of the number of cotton swabs to be tested to the total number of cotton swabs in the same batch is selected to be 1:300. Pulling force moves away from the fiber head at a speed of 500mm / min until the fiber head comes out of the cotton swab. The clamping seat 5 is provided with a plurality of annular chambers 1 with built-in magnetorheological fluid. The annular chamber 1 is an elastic structure and its inner hole diameter is 0.3 mm larger than the diameter of the cotton swab to be tested. The outer surface of the annular chamber 1 is A coil 3 is wound, and a power supply 4 is connected in series with the coil 3 .

[0045] In the specific implementation process, when selecting the cotton swabs to be tested, the total number of cotton swabs in the same batch is selected according to a certain ratio. In this embodiment, the extraction is performed accor...

Abstract

The invention relates to the technical field of testing methods, and discloses a method for testing the pulling force of a cotton swab fiber head. The method comprises the following steps that step 1,a plurality of cotton swabs in the same batch of cotton swab products are selected for detection; step 2, the to-be-detected cotton swabs are fixedly clamped; step 3, cotton buds on the cotton swabsare pulled, and a tension machine records the pull-out tension; step 4, the average value of the pull-out tension is calculated for comparison. The invention aims to detect the pulling force of the cotton swab fiber head to calculate whether or not the numerical range of the pull-out tension of the whole batch of products can meet the use requirements; the quality of cotton swab products is also ensured, and the dangerous situations that the human body is damaged due to the phenomenon that the fiber head is pulled out frequently is avoided.

Description

technical field [0001] The invention relates to the technical field of detection methods, in particular to a method for testing the pull-out force of a fiber head of a cotton swab. Background technique [0002] Cotton swabs are made of medical fiber heads and rods, and the rods are mostly made of bamboo, wood, plastic or paper. Cotton swabs are widely used in medical, beauty, makeup, cleaning, inspection and other industries. Although the cotton swab is small, it has a great effect and is an indispensable auxiliary product in life. [0003] At present, there are only testing standards for medical fiber heads at home and abroad, but there are currently no relevant testing standards for testing the firmness of the connection between the fiber head and the rod body at home and abroad. The pull-out force of the cotton swab fiber head in the cotton swab is the most critical item, because the cotton swab may be inserted into a small hole and then pulled out during use, or it may...
