Description

Needle grinding machine

Technical Field

The utility model relates to a needle grinding machine.

Background

After the card clothing is used for a period of time, the steel needles are abraded, and the abrasion degrees of the steel needles of the same card clothing are different due to different pressures, fiber impurities and the like at different positions. The common needle grinding machine is a long grinding roller type needle grinding machine, the long grinding roller is arranged at the foremost end of the needle grinding machine, and the long grinding roller rotates to grind card clothing. However, in order to ensure the uniformity of fiber carding, the long drum type needle grinding machine needs to grind steel needles to a uniform length. In order to increase the carding efficiency of the fibres, the grinding rollers are designed to be longer and longer. The longer the length of the grinding roller is, the larger the length difference of the steel needles with different abrasion degrees after being ground is, thereby influencing the carding quality of the fibers. Therefore, people usually adopt the short grinding roller to replace the long grinding roller to polish the needles with different wear degrees of the same card clothing in a grading way, so that the lengths of the polished steel needles are consistent. However, when the commonly used short grinding roller slides on the rail, the moving distance is easy to appear in the front and back direction, so that the problem of low grinding precision is easy to appear when the steel needle is ground.
