This belt grinder makes use of an Arduino Opta micro PLC

A mainstay in most machine retailers, the belt grinder assists in significantly growing the velocity at which elements could be floor down in a safer, extra managed method in comparison with an angle grinder. As an effort to construct a device like this one for the primary time, Julien Alexandre selected to make use of the Arduino Opta as its controller whereas designing it from the bottom up.

Belt grinders, because the title implies, use a quickly transferring, abrasive belt that has been wound round a set of pulleys and will get pushed by a big motor. The primary drive pulley was mounted on the rear of the machine and securely linked to a three-phase AC motor. Above it’s a height-adjustable level for controlling the belt’s stress, which additionally aids in swapping belts when wanted. The final two pulleys are located throughout from the motor and could be tilted vertically to change the grinding angle. Lastly, your entire meeting can pivot to put flat on the desk or raised at an angle to it.

Facilitating the belt grinder’s operation is an Arduino Opta micro PLC. It receives a sign from two digital inputs that, when both is energetic, trigger the Opta to blink a blue LED indicating to the operator that an error occurred within the safety relay that manages the protection chain.. The motor controller (a variable-frequency drive) receives its values from a change and a potentiometer positioned on the management panel, with the previous dictating if the system is energetic and the latter getting used for adjusting the velocity.
