Abstract
A powder supply device is configured to manufacture dry electrodes. The powder supply device is configured to continuously supply cohesive powder used in manufacturing the dry electrodes to an electrode manufacturing device while evenly dispersing the powder using vibration feeders. The vibration feeders have, on a bottom plate of each of the vibration feeders, a plurality of supply amount adjustment grooves arranged at an equal interval in a width direction. The vibration feeders are configured to move the powder along each of the supply amount adjustment grooves and to continuously supply a predetermined amount of powder to the electrode manufacturing device.
Claims20
A powder supply device configured to provide powder for manufacturing dry electrodes, the powder supply device comprising:
- a powder storage hopper configured to store the powder for manufacturing the dry electrodes and to discharge the powder;
- a powder metering supply device configured to measure and discharge a predetermined amount of the powder discharged from the powder storage hopper;
- a first vibration feeder configured to disperse the powder discharged from the powder metering supply device;
- a second vibration feeder that is arranged at an outlet of the first vibration feeder and configured to receive the powder discharged from the first vibration feeder, the second vibration feeder having a plurality of first supply amount adjustment grooves that are defined at a bottom plate of the second vibration feeder and arranged at an equal interval in a width direction;
- and
- a third vibration feeder that is arranged at an outlet of the second vibration feeder and configured to receive the powder discharged from the second vibration feeder, the third vibration feeder having a plurality of second supply amount adjustment grooves that are defined at a bottom plate of the third vibration feeder and arranged at an equal interval in the width direction.
