1756-IF8 Single Slot Module

1756-IF8 can be used as glaze firing of products and as plain firing. When used as a plain firing, the billet on the conveyor belt is billet, mechanical strength is lower than the glaze billet, the process requires no bruises, etc.; when used as a glaze firing, the process also requires that the billet is not allowed to stack, etc.. Therefore, in the transmission process, should run smoothly, the transition at the articulation of natural, slow belt lift. These requirements can be adjusted from the conveyor belt and the control of the motor (such as the use of frequency control), as well as the transformation of the solenoid valve to solve.

1756-IF8 by the motor M4, M5 control roller table rollers, due to long-term work in a higher temperature environment, will inevitably produce bending deformation, etc., so that the kiln billet arrangement disorder, or even cascading adhesion and produce scrap. Usually this phenomenon is monitored manually, which is time-consuming and laborious, the author has added two photoelectric detection tubes G5 and G6 in Figure 1, which are connected to the alarm circuit and PLC, and successfully realized automatic monitoring.

The machine in the trial run, from time to time, the phenomenon of downtime. The reason is mainly because the ambient temperature is too high, resulting in PLC automatic protection system action. Industrial ceramic kiln ambient temperature is high, is a very common problem. But did not cause the designers to pay enough attention to the PLC control cabinet, although the low-temperature section of the roller kiln from a certain distance, but the PC machine and the control of the motor’s magnetic and other electrical components, at the same time, the control panel is sealed in a smaller space, and the cabinet without a fan, poor heat dissipation. The rising ambient temperature in summer, coupled with limited ventilation in the production plant, resulted in frequent PC machine downtime. When the cabinet fan was added, there was no more downtime.
