Electronic and electrical control systems
The basic composition diagram of the electronic and electrical control system of the projectile loom is shown in Figure 4-19. It mainly includes sensor 1, amplifier box 2, shuttle counter 3, emergency stop button 4, and stop button 5. Warp detector 6, electronically controlled shuttle maker 7, projectile monitoring sensor 8, signal light 9, control box 10, angle sensor 11, holding electromagnet 12, feeder socket 13, controlled lubrication system 14, limit switch 15. Main motor 16, power supply 17, automatic weft finding device 18, sensor 19 for identifying mechanical faults, motor let-off device 20, etc.
The control box in the electronic and electrical control system of the P7300 projectile loom has higher maneuverability and sensitivity to meet the requirements of optimizing the weaving process. It adopts the design concept of centralized control of all functions, with a neat, clear and reasonable layout. , and introduce a new wiring concept of “direct from source to target”. It adds support for the transverse cross function, automatically corrects the weft yarn detector, automatically optimizes the shuttle braking function, and expands the data statistics function. The P7300 projectile loom electronic and electrical control lever includes a basic box and an optional box, the diagram of which is shown in Figure 4-20. It mainly consists of computer hardware, drives, electrical parts, power supply parts, etc.
The P7300 projectile loom is equipped with operation panels on the shuttle side, center and shuttle side of the loom. The button functions on the operation panel are shown in Figure 4-21.
The terminal of the electronic and electrical control system of the projectile loom is a touch screen. The touch screen is equipped with the overall synthesis of the control mechanism, fabric tissue control system, data management system, operation record book, statistical data, diagnostic instructions and assistance. system. The overall synthesis of its control mechanism is shown in Figure 4-22. The data governance system is shown in Figure 4-23.
