Ways to increase the holding force of the spinning machine

Spinning machine

Draw ratio should be to trace the regulation, so in the transmission system of the drafting unit, often without tooth chain CVT or gear type gearbox. If the joint production of a variety of fiber is not much, but also can be used to change the change of the gear to change the tension.

The running speed of the combination machine by the third drawing machine roller surface line speed represents, and combined with machine processing capacity is refers to the finished fibers the total denier. A drawing machine usually consists of five, six, seven or nine rolls to form a group. Their diameter is the same, the same speed, they and other drawing machine a set of drawing roller speed different, depending on the speed of the poor, drawing machine complete stretching. So improve the gripping force of tow drawing roller, to prevent slipping ensure drawing ratio stability.

Is the way to increase the holding force:

(1) before the tow feeding drawing machine has a certain tension to;

Increase (2) tow on the roller wrap angle or increase the frictional resistance between the roller and the tow, but increase wrap angle, will also increase the tow tangle and opportunity, is disadvantageous to the operation;

(3) to increase the number of roller, and seven and nine and is currently mostly used, five and six and drawing machine has rarely manufacturing; (4) above or below the drafting and increase pressure roller, tow skid prevention, improve the ability of drafting.

The lower part of the seven roller drafting mechanism of the first and seventh drafting roller, pressure roller standing. Roller coated with rubber to increase the friction coefficient, effectively holding the tow. Pressure roller can be used in the cylinder pressure or the pressure of the cylinder is a simple operation of the mechanism is convenient and will not pollute the environment. Generally with two cylinder pressure, also can be a cylinder through a connecting rod to pressure.
