1, the cylindrical shaft head replaced by a conical shaft head, the axis the core all using alloy steel and special heat treatment, so that there is a high flexural strength, high speed shaft body does not bend. Overcome the traditional shaft sleeve handcrafted flowers often because deformation of the shaft head, causes the sliver to a mechanical wave, resulting in the phenomenon of regularity and evenness.
2, between the shaft and sleeve axial movement (conventional shaft and sleeve of the axial clearance of 1mm-4mm, and the new shaft and sleeve of the axial clearance is 0.8mm), so that the skin roll in the fiber sliver drafting and close process variable speed point distribution is more uniform, longitudinal friction distribution is more balanced, ensure and roller operation stability, so that the draw frame sliver quality long-term stability and improved .
3, double needle - ball composite bearings instead of the original needle bearing, making the friction heat down to solve the roller due to fever caused by the handcrafted flowers and damage to the shaft and sleeve, reducing the consumption.
4, the sleeve labyrinth form of dust, anti-spill design, internal oil storage space, good lubrication conditions, and selection of imported advanced grease can be two years without refueling, changing the 7-10 days necessary to refuel. to avoid the often refueling easily contaminated sliver, but also reduce the labor intensity of workers often grease.
