Textile Material Back Elastic Test Machine For Shoes

< p > > Description: < a href= "http://? Www.sjfzxm.com/news/index_c.asp" > instrument < /a > includes pendulum bar, impact hammer and impact blade. When the pendulum is vertical, the impact blade lightly touches the surface of the sample. When the pendulum is impacted, it will be 90 degrees to the horizontal plane, and the hammer head will impact the sample horizontally when it is impacted, and it will be perpendicular to the surface of the sample.

< p > test the mobile pendulum to the level, drop the pendulum to let it fall freely, impact the blade after impact test, < a href= "http://? Www.sjfzxm.com/news/index_c.asp" > rebound > /a >, read out the degree of the angle between the pendulum and the vertical horizontal direction when springback, so as to calculate the resilience of the sample.

< p > in the embedded sawtooth tin cylinder inlaid flower, it usually occurs in the first group and the third group. The tooth face angle is 90 degrees, and the 4 segmental cylinder inlaid flower occurs in second groups. The first row of tooth pieces of the set of flower sticks has been damaged by the observation of 60 times magnifying glass in 90 groups and five groups.

< p > if the inlaid flower caused by cylinder damage is not able to solve the problem of inlaid flower by adjusting the depth of brush insertion into the cylinder, increasing the brush speed and improving the cleaning time of the brush, it is possible to achieve the goal only by removing the old rack and replacing the new rack.

< p > the influence of Xilin inlaid on the yarn quality is greater when the cylinder's sharpness is deteriorated or the damage of the rack teeth is caused by the damage of the rack teeth. It shows that the percentage of droppings increases by 0.5 percentage points when the same noil spacing and cylinder grooming spacing are applied.

Production practice showed that the short staple rate of combed sliver and combed sliver increased, and the yarn quality deteriorated rapidly.

< /p >

< p > when the conventional technical measures for processing Xilin are not effective, do not haste to adjust the depth of the brush palm into the cylinder. This will not only be harmful to the processing of Xilin inlaid flowers, but will also aggravate the damage of brush hair and shorten the service life of the brush.

If the brush is used properly, the imported brush can be used for 6~7 years, and the domestic brush can be used for 4~5 years.

< /p >

< p > brush oriented use is equivalent to inserting the brush into Xilin depth by 1 millimeters. This technology can effectively and thoroughly remove the inlaid flowers in Xilin toothed sheet.

Now we have all replaced the domestic brush. This is mainly due to the poor elasticity of domestic brush hair. After a period of time, the brush bristles will be dumped to one side, which will greatly reduce the cleaning efficiency of the brush.
