Main use of the product
BN320 type double twisting machine is mainly used for twisting of polyester, nylon, polypropylene and other raw materials, achieving one turn and two turns, the production efficiency is doubled compared with the traditional twisting machine, the package capacity is large, the energy consumption is low, and the operation is convenient. , simple maintenance and other characteristics. And the computer speedometer automatically displays the spindle speed, the roller line speed, the yarn length and the fixed length self-stop control.

Main structure of the machine
The double twisting machine is composed of a head box, a frame, a twisting spindle, a wire feeding device and a winding portion.
First, the rack
The frame of the double twisting machine is the skeleton of the whole machine, and the spindle, the feeding device and the winding device are mounted on the frame.
1. Structure form: multi-section combination
2. Structural features: The steel plate is used as the wall board, and there are 5 beams in the inside, which is convenient to install and adjust; the rigidity and strength are good, and it is double-sided operation.
Second, the transmission part
The transmission parts are all centralized transmission of the whole machine.
The transmission part is concentrated in the front and rear of the car. The flat cylinder is driven by the motor gearbox, and then the gearbox is driven by the sprocket to feed the roller, and the flat cylinder shaft is driven by the worm gear reducer to drive the traverse forming portion.
Third, the spindle part
The belt has friction transmission, the transmission is stable and reliable, the difference of the spindle speed is small, and the tension of the belt is convenient.
Fourth, the wire transfer part
The cam rotation drives the wire transfer rod to make a linear reciprocating motion at a constant speed.
Five, overfeeding part
The super-feeding wheel is held by a pair of intermeshing grid wheels and sent to the winding part. The linear speed of the yarn on the yarn is greater than the winding speed of the yarn, and the super-feeding is used to improve the quality of the yarn winding forming. The size of the overfeed can be changed by changing the wrap angle of the yarn on the superfeed wheel.
Sixth, the winding part
The twisted yarn is wound on the bobbin by a super-feeding wheel with a certain overfeeding amount. The bobbin chuck clamps the bobbin and presses on the rubbing roller with a certain pressure under the action of the spring. The drive is wound.
