Construction

Main Motor has 2 parts. Part 1 will connect to the roller system by using rubber band. Part 2 will connect to the gear system. The motor use 220V power and speed at 1200rpm. Torques of this motor is 0.86 N.m. The back of motor connect to the truss system. Colling fan (size 80cm x 80cm) helps to reduce heat from the main motor.

​

Top of machine is funnel connect to roller system. The roller system has 3 main parts. Top cover, sides and two rollers. Top cover using aluminum material with dimension 1.4 inch width and 6 inch length. Top cover keeps beads fall out of the roller. The funnel will connect to the top cover of the machine. Sides part’s dimension are 1.14 inch width and 2.36” length. Sides parts function to hold the roller system. Connect the rollers with ball bearing.

​

Gears system has 5 gears. 4 gears with 32 teeth and 1 gear with 28 teeth. Gears will connect with plastic elevator to delivery bead from the roller system. Pair gear 28 teeth and 32 teeth will connect through KCM 25H chain with 62 links. This pair of gear will connect to the motor to run the gears system.  

​

The beads go through the funnel to the roller. Top cover prevents bead fall out of rollers. Beads will drop to the gear system through 24 inch needle. This needle will go around the gear system in order to deliver the beads to the final destination. Since beads place on roller, the roller run will make bead roll, therefore, the center of bead will go straight to the needle.

The base will be welded and back support will mount to base with angle of 5 degree. With this angle, the beads and fall to gear system through needle by the gravity.
