Document Type and Number:
Japanese Patent JP2019052013
Kind Code:
A
Abstract:
To provide a powder particle spraying device and a method for spraying a powder particle capable of spraying powder particles on a continuously conveyed base material evenly and well quantitatively in a width direction of the base material.SOLUTION: A powder particle spraying device 1 includes a hopper 2 provided with a storage part 20 and a discharge port 23, and a conveying spraying part 3 for spraying powder particles P discharged from the discharge port 23 on a base material 100 continuously conveyed. The conveying spraying part 3 is constituted including a tabular receiving part 30 for receiving the powder particles P and a vibration generating part 31 for vibrating the receiving part 30, and operates the vibration generating part 31 to vibrate the receiving part 30, whereby the powder particles P on the receiving part 30 are conveyed in a predetermined direction. The vibration generating part 31 is operated at a frequency in which a value of an inclination m of a calibration curve determined from a relation of an amplitude N of the vibration generating part 31 with a spraying amount Q of a plurality of the powder particles P conveyed in the predetermined direction and sprayed on the base material 100 is larger than 0 and 0.4 or less in terms of a value shown as a variation.SELECTED DRAWING: Figure 1
