Description

Technical Field

[0001] The present invention relates to the technical field of accessories for powder shaking machines, and particularly to a powder shaking box with a powder saving function. Background Art

[0002] The powder shaking box is the part in the powder shaking machine for powder shaking work. The working principle of the powder shaking machine is that the printing medium already coated with ink is evenly distributed with powder at the front end of the powder shaking machine; the distributed powder is printing powder, which can form a transparent layer covering the pattern formed by the ink and the printing medium after melting. Therefore, in addition to the powder shaking box, the powder shaking machine also includes a powder distribution box and a drying chamber; the powder shaking box is arranged between the powder distribution box and the drying chamber. Generally, the powder shaking box includes a box body, a tension roller, and a cloth beating roller; the tension roller and the cloth beating roller are respectively and horizontally installed inside the box body in sequence. The printing medium passes through the inside of the box body; the printing medium passes under the tension roller and then over the cloth beating roller. The tension roller restricts the printing medium to ensure that the printing medium enters the drying chamber in a tensioned state; the cloth beating roller rotates to hit the bottom of the printing medium to shake off excessive printing powder attached to the printing medium. However, during the flow of the printing medium, the excess printing powder will fall to the bottom of the box body; the powder shaking box in the prior art is provided with a circulating powder system to reuse the powder falling to the bottom of the box body, that is, the real-time consumption of the printing powder in the powder shaking box is the sum of the powder amount combined with the printing medium and the powder amount in the circulating flow of the printing powder. The circulating powder system in the prior art can continuously convert the printing powder in the circulating flow of the printing powder into the printing powder combined with the printing medium, but cannot control the powder amount in the circulating flow of the printing powder, that is, the prior art cannot reduce the real-time consumption of the powder shaking box.
