The warp stopping electrical box has the following main applications on weaving machines:
1. Fault detection and signal transmission:
Detecting warp breakage: During the operation of the loom, the warp yarn is in a tensioned state and constantly shuttles. The warp stop piece is worn on the warp yarn, and under normal circumstances, it is supported by the warp yarn and suspended on the warp stop strip. When a warp yarn breaks, the corresponding warp stopping piece loses the warp yarn bundle and falls onto the warp stopping strip. At this point, the circuit status on the stop bar changes, and the stop box can detect this change and convert it into an electrical signal. For example, the chip on the stop bar was originally in an insulated state with the package iron. After the stop bar breaks, the drop of the stop bar makes the chip and the package iron conductive, and the stop bar electrical box will receive this signal.
Transmission signal: After the warp stopping electrical box detects a broken warp signal, it will transmit the signal to the control system of the loom. Upon receiving the signal, the control system will immediately stop the loom to avoid quality problems such as fabric defects caused by untreated broken warp. Afterwards, the stop worker can find the position of the broken warp according to the instructions of the warp stopping electrical box, perform the continuation operation of the warp yarn, and then resume the operation of the loom.
2. Control the operation of the weaving machine:
Shutdown control: The signal output of the shutdown electrical box is directly related to the start and stop of the loom. Once a broken warp signal is detected, it will quickly send instructions to the main control system of the loom to stop running, ensuring the controllability of the production process and product quality. This fast response shutdown function is very important in preventing a large number of defective products caused by broken meridians.
Collaborate with other components: The warp stopping electrical box cooperates with other electrical components and control systems on the loom to achieve normal operation of the loom. For example, it may interact with the warp feeding mechanism, winding mechanism, etc. to coordinate the working rhythm of each component based on the running status of the warp yarn and the production progress of the fabric, ensuring the efficient and stable operation of the loom.
3. Fault diagnosis and display:
Fault prompt: When the stopping electrical box itself or its related stopping strips and other components have faults, such as poor circuit contact, sensor damage, etc., the stopping electrical box can prompt the operator with fault information through specific signal output or indicator light display, so that maintenance personnel can discover and eliminate the fault in a timely manner.
Segmented display: In some excellent weaving machines, the warp stopping electrical box also has segmented display function. Due to the large number of warp yarns on the loom, it is difficult for the stop worker to quickly and correctly locate the broken warp position once it occurs. The segmented display function can divide the stop passage into several sections, each corresponding to one or more detection areas of the stop passage electrical box. When a break occurs in a certain section, the corresponding indicator light or display screen will light up, indicating the approximate location of the break, greatly improving the efficiency of the stop passage search by the driver.
4. Protecting circuit safety:
Current limiting protection: There may be various interference factors in the working environment of the weaving machine, such as electromagnetic interference, voltage fluctuations, etc., which may cause an abnormal increase in the current flowing through the stopping electrical box and stopping strip. The current limiting circuit in the circuit breaker box can limit the magnitude of the current, prevent excessive current from damaging the circuit, and ensure the normal operation of the circuit breaker.
Overvoltage protection: When the power supply voltage of the weaving machine is too high, the protection circuit of the warp stopping electrical box can limit the excessive voltage within a certain range, avoiding damage to electrical components due to overvoltage and extending the service life of the warp stopping electrical box.
