Knowledge About Cloth Spreading Machine

Are all functions of cloth spreading machine? computer control Cognition with non computer control: positioning control of cloth spreading machine. (add Maple creative / digital 2000) computer control: the stop position (value) at the left and right ends is remembered by computer. Features: you can see the position of the left and right ends in the data display, and the position of the cloth laying machine in real time. Advantages: easy to change the location of the shutdown. Because the computer always knows the location of the cloth laying machine and the location and distance of the shut-down point, it is absolutely accurate to control the shutdown position. (other brands) non computer control: it is necessary to install electromechanical collision stop devices at both ends of the cutting bed. Features: when changing the stop position, the collision stop device needs to be moved to the new location. Disadvantages: changing downtime is more annoying. The clearance of the collision is large, resulting in inaccurate location. The change of speed and inertia force of cloth spreading machine also result in inaccuracy of stopping position. Inaccurate location is the reason for wasting cloth.

Speed control of cloth spreading machine. (add Maple creative / digital 2000) computer control: the movement of the cloth spreading machine is controlled by the precise software of the computer. Characteristics: change speed only through data display, easily change the value of walking speed. Advantages: the cloth spreading machine is heavy and high-speed mobile equipment. Only advanced robot control technology can make the cloth spreading machine move freely and play the perfect cloth spreading function. (other brands) non computer control: the speed of the cloth spreading machine changes, only by reducing the power supply to the motor. Disadvantages: to change the deceleration buffer before stopping, it is necessary to re adjust the distance of the slow track. In addition, the speed and position of cloth spreading machine can not be accurately controlled by weakening the power supply of the motor alone.

Cloth spreading machine Synchronous cloth feeding control 。 (add Maple creative / digital 2000) computer control: use computer precision software to control synchronization. Features: to change the speed of cloth delivery, it is easy to change the value of cloth delivery speed through data display. (other brands) non computer control: use mechanical continuously variable transmission. Features: to change the speed of cloth delivery, it is necessary to turn the ring with no change in speed. The cutting function control of cloth spreading machine. (add Maple creative / digital 2000) computer control: all functions are computer controlled. Advantages: (other brands) non computer control: use electromechanical logic control. Features: function can not be chosen. Disadvantages: function can not be chosen. In addition, the control method is more comprehensive and the damage rate is higher. Various control modes used by today's paving machines: (add Maple creative / digital 2000) (Advanced) full computer control mode: the use of computer central processing unit (CPU). Hundreds of control software developed by cloth producers are stored permanently in the central processing unit.

The control software is developed by the cloth spreading machine manufacturer, and the manufacturer can continuously update and improve the control software in order to meet the needs of the cloth spreading machine, so that the cloth laying effect will always maintain the highest level. Semi computer control mode: the use of commercially available programmable logic controller (PLC). The cloth spreading machine manufacturer applies these functions to the control of the cloth spreading machine in response to the range of functions that can be provided in the programmable controller. The functional specifications provided by the PLC can not accommodate the actual needs of the cloth laying machine within a certain range. Cloth spreading machine The design to accommodate the function of programmable controller often makes the result not ideal. (very backward) traditional mechanical and electrical logic control mode: using complex logic circuit with high damage rate and logic control, this ancient control mode needs to operate with a large number of parts such as mechanical transmission and mechanical transmission. Disadvantages: design review and production cost is high, plus the limit of technology, it is impossible to achieve precise control in operation, the effect of cloth spreading is not ideal, and the defects are more likely to be damaged.
