Specifications: With 5 full-automatic functions of Model G203 (the former SG193) vertical weft winding machine: automatic taking out of and winding safety yarn (reserve yarn), automatic winding and forming after resetting, automatic stopping when the bobbin is full, automatic descending the yarn guide plate, and automatic taking out of and winding the tail yarns. Also, it is with the following features: The weft missing is completely removed away. Principle: Abolish all complicated and easy workout gears transmission. The worm gear pair directly drives the cam. And adopt 1:1 forming cam curve, Increase the winding screw-pitch to 1.2mm. the large screw-pitch and the net-shaped winding effectively control the weft missing. The energy-saving and efficiency-increasing rate reaches to more than 50%. Also save the land occupation area. Principle: Design the spindle speed to be 3500r.p.m to the most. The time for the bobbin to be full is only half of that of the old model. Its production efficiency can improve by half. The motor's energy consumption thus is reduced by 50%. Very convenient and easy in changing yarn's kinds. Wide yarn scope. Principle: With the consideration of all related factors in design. The changing of yarns is realized by adjusting the ratchet wheel's bracing teeth. The winding scope is enlarged to 3SW-100SW. Simple headstock, large space, complete functions, low trouble rate. Principle: Abolish all the gear transmissions. The machine runs smoothly and reliably with low noise. The doors on the headstock cabinet are open in three sides. Large space. Wires and switches are built-in. Users can install daylight lamps at each section according to their needs. The electric appliances cabinet's door is installed with a switch that is with a lock for the convenience of users. Smooth and stable yarn guide. Good shaping. Principle: Abolish the gear transmission. The yarn guide plate moves up and down smoothly. There is no overlapping of winding. And the 1:1 cam moves up and down evenly. Good large screw-pitch winding and shaping quality. No damage to the main shaft. Principle: The motor drives the belt pulley to directly drive the main shaft. And when The machine is started it is under the overload-protection. So even the machine runs for a long time the main shaft wilt not be damaged. The whole machine adopts the imported electrostatic plastic spray technique to achieve a clean, tidy, and beautiful outlook. Principle: The machine bed adopts the imported electrostatic plastic spray technique to make the accuracy of the machine and the outlook of it reach to the imported machine's level.
