Product description

What this machine does

  • The automatic positioning and dispensing can accurately drip the varnish on the same area of each stator to achieve a unified standard. ◆ Automatically detect if incoming materials are available, and then start to continuous dispensing operations. Or intermittent dispensing operations for small amount of armatures to reduce the loss of varnish. ◆ Dripping area is isolated and has an independent ventilation system in order to avoid varnish smell spillage. ◆ In addition to the varnishing dripping system, this model can connect the ring neck glue automatic dripping system, therefore varnishing and ring neck glue dripping can be done one time. This can effectively reduce dripping time. ◆ Double shaft end ejecting mechanism, no need to replace the fixture and stator runs smoothly without shaking. Prime quality on varnish absorbing and drying. ◆ Fixture adjustment adopts snap-type design without the use of tools. Quick fixture adjustment. ◆ Revolution and rotation are controlled independently. Stator transfer setting (revolution) and rotary speed can be set up according to the characteristics of the stator and varnish. ◆ Equipped with automatic transmission tension adjustment mechanism and automatic overload protection mechanism. ◆ Equipped with rotation speed compensation function. Rotation speed will not be affected by revolution. ◆ Preheat zone and hardening zone is independently controlled. Maximum temperature is 180℃ ◆ Unique hot air circuit design greatly reduce hot air outflow at the inlet and outlet which effectively improves the electric heating efficiency. ◆ Adopts PID temperature control module + SSR current control module to control the accuracy of the temperature in the furnace±2%. ◆ The control system adopts Industrial PLC with a 10" HMI touch panel; operation status and running-monitor data are displayed in real time. ◆ Ergonomic operator interface with real-time manual/automatic switching, operation monitoring, automatic maintenance prompts and automatic fault detection. Stores up to 100 sets of working parameters for rapid model changeovers. Supports remote programme monitoring and maintenance. Machine size, layout and output rate can be tailored to the application; a manual glue dispenser is available as an option.
