Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ironing picture printer, especially to the large capacity powder bin for powder shaker. BACKGROUND

[0002] The ironing picture printer prints a pattern on a heat transfer printing ironing picture film in the working process, and then scatters hot melt powder on the heat transfer printing ironing picture film with the pattern, so that the hot melt powder adheres to the pattern on the heat transfer printing ironing picture film. The heating device melts the hot melt powder on the pattern on the heat transfer printing ironing picture film, so that the hot melt powder adheres firmly to the heat transfer printing ironing picture film. In this process, the hot melt powder outside the pattern on the heat transfer printing ironing picture film needs to be shaken off to avoid the hot melt powder adhering to other places of the heat transfer printing ironing picture film. The powder shaker is used to complete the powder shaking work.

[0003] However, the powder bin of the powder shaker is a device for storing raw materials of the powder shaker. When the hot melt powder in the powder shaker needs to be replenished, the powder bin needs to be opened to replenish the raw materials of the powder shaker. The traditional powder bin has a small capacity and needs to be opened or closed manually. The amount of hot melt powder is controlled by experience, but such a way has low precision and large error. UTILITY MODEL CONTENT

[0004] Therefore, it is necessary to provide a large capacity powder bin for powder shaker to solve the technical problems of the traditional powder bin with small capacity, manual opening or closing, low precision, and large error.
