Model HMG4000 Autocompnic Pirn Winding Machine is a kind of new
weft winding equipment improved from Model HMG2000 and HMG3000. It
is the most advanced in the preparatory industry of textile weaving
and tatting to roll or wind the bobbin yarn into woof yarn for
weaving. The machine is suitable for winding different yarns (silk
threads) such as pure cotton, trueran, ramie, low elasticity
filament, mid fibre, etc.. The machine adopts the latest numerical control technique and the
most advanced automated equipment instead of the traditional
mechanical transmission. Its core technique contains a supreme high
scientific technology content. It is a revolutionary breakthrough
in weft winding machine's manufacture technology, It breaks free
from the conservative ideology of those so-called "designers" or
"engineers". And it leads forward a tidal wave of reconstructing
the preparatory equipment to make them automated. This model's automatic control system is made and improved from the
present Model 2000 by overcoming its many imperfections in hardware
configuration and software programming. Mainly, it introduces and
adopts the programmable digital movement logical controller, LCD
Chinese displayer human-computer interface, stepping subdivided
servo driver, and high-performance large-torque stepping motor.
Composition of the system: The human-computer interface adopts the top-class touch screen.
(Monochrome screen or 256-colour screen are selectable according to
users' needs. The standard type is 5.7" monochrome screen 16
gamma.) PLC programmable digital movement logical controller. Subdivided servo stepping driver. High-performance large torque stepping motor. High human-computer interface intelligent degree. The system adopts the touch screen, PLC, LCD Chinese displayer and
menu keyboard. The human-computer interface is friendly. The operation is visual
and easy to understand. Easy and convenient operation. Suitable for all kinds of yarns. Thanks to the abolishing of complicated and easily worn-out
mechanical parts, the machine can be suitable for winding all kinds of yarns. All parameters are
adjustable at random. The change of yarns is finished just by
setting in a very short time. Cost reducing, energy saving, and labor saving. Thanks to the abolishment of traditional complicated and easily
worn-out parts, a lot of costs on parts are saved. The output of it
is double of that of the mechanical type on the base of the same
spindle quantity. While the human labor and energy consumption is
only half of the mechanical one. So it indeed reduces down the cost
and consumption. Smooth and stable movement of yarn guide plate. Good shaping effect
of line pipe. The adoption of stepping subdivided servo driver realizes the
subdividing and adjusting of the yarn windings, makes the yarn
guide plate go up and down correctly and steadily, makes the line
pipe form well, and completely gets rid of the weft omission or
weft missing. Functions of subdivided drive and self-protection in stopping. Can adjust the drive electric current according to the length of
machine. The system checks its operation state by itself at any
moment so as to realize the self-protection in case of
over-current, overpressure, or under-voltage. Every time when the
yarns are fallen, the system automatically realizes the pick-up
function and the self-lock function of stepping motor and driver in
low pressure and constant current. Eliminate the motor's vibration and noise The improvement of hardware and software in the system makes the
stepping motor be hard to be heated abnormally or produce any
abnormal noise or vibration. It validly improves the working
environment and the system's performance, lowers down the trouble
rate, and prolongs the stepping motor's usage life. Newly increase the functions of stopping on route and continuing
work. If it is needed to stop the machine during the operation, then you
can press "PAUSE" key. And then you press "CONTINUE" key on the
control panel to continue to work.
