The nozzle assembly wire roller design roller surface should wear, and does not react with tow oil agent. Pressure and have two types: self tightening type pressure and has two kinds of pressure, a is by pressure and weight of tow pressure, pressure roller on the tow pressure with the change of the tow tension change. Another addition to gravity pressure roller, and the cylinder to the tow grip between the tow roller and reliable, not easy to slip. The loading roller is according to the relative position of roller and drawing roller is different, can be divided into the upper pressure roller and the lower roller. The former is mostly used for shorter length of roller drafting small stretching mechanism, by single cylinder with pressure, total pressure cylinder and pressure and weight. Roller pressure is used for large-scale drafting mechanism. At this time, total pressure as the pressure in the cylinder and pressure and weight difference, cylinder pressure can be partially offset by drawing roller cantilever end deformation.

Composition of the joint machine

Short fiber processing machine is composed of by bundling machine, drawing machine, tension heat setting machine, crimping machine, thermal relaxation stereotypes machine, cutting machine, packing machine etc. unit.

Process: storage, cluster, the breaker, stretching second extension, three stretch, tension heat setting, curly, relaxation heat setting, cutting and packing.

Joint machine drive

After the short fiber processing machine, from eight roller guide wire machine, first drafting machine until the oiling machine is usually used to long side shaft collective drive. Long side shaft transmission using a DC motor through the transmission gear box, gear box and the long axis, respectively, the transmission is connected to all the equipment, in order to meet the requirements of synchronous operation. While the curling machine, relaxation heat setting machine, cutting machine and packing machine, etc. by a separate motor drive.

The advantages of long side shaft drive:

(1) the transmission is stable and reliable.

(2) the synchronous operation of the drawing machine, drawing ratio constant.

(3) can facilitate the low-speed operation, students head and remove the broken filament, convenient operation.
