Abstract

According to the high-stability powder shaking machine for the heat transfer printing machine, hot melting powder falls on a heat transfer printing heat transfer printing film, a second driving motor drives a beating frame to rotate through a second speed reducer and a second driving shaft so as to beat the back face of the heat transfer printing heat transfer printing film, and in the process, the back face of the heat transfer printing heat transfer printing film is beaten; the static electricity eliminator carries out static electricity elimination treatment on the heat transfer printing pyrograph film through the flapping frame, and the situation that hot melting powder is adsorbed to the positions, except for patterns, of the heat transfer printing pyrograph film due to static electricity is avoided. And the shaken-off hot melting powder falls into the bottom of the powder shaking bin, and the second vibration motor drives the bottom of the powder shaking bin to vibrate, so that the hot melting powder enters an input port of the conveying cylinder along the inclined bottom. The third driving motor drives the conveying shaft to rotate through the third speed reducer, so that the spiral conveying blade conveys the hot melting powder at the input opening of the conveying barrel to the output opening in the top of the conveying barrel and conveys the hot melting powder to the input end of the powder discharging box. The first vibration motor drives the lower powder box to vibrate, and the hot melting powder is evenly dispersed to the bottom of the lower powder box along the obliquely-arranged lower powder box.

Description

Technical Field

[0001] The utility model relates to the field of powder shaking machines, in particular to a high-stability powder shaking machine for a heat transfer printer. Background Art

[0002] During operation, the heat transfer printer prints a pattern on the heat transfer film, and then sprinkles hot melt powder on the heat transfer film with the pattern printed on it, so that the hot melt powder adheres to the pattern on the heat transfer film. The heating device heats and melts the hot melt powder on the pattern on the heat transfer film, so that the hot melt powder adheres firmly to the heat transfer film. In this process, the hot melt powder outside the pattern on the heat transfer film needs to be shaken off to prevent the hot melt powder from adhering to other places on the heat transfer film.

[0003] However, traditional powder shaking machines all have a powder box at the bottom of the powder shaking box to receive the hot melt powder that is shaken off. After the powder box is full, the hot melt powder in the powder box is manually put back into the powder spreading mechanism. In order to improve the powder recovery efficiency, powder shaking machines with powder recovery functions have appeared on the market. For example, the application number is CN202223470519.5, and the patent name is a technical solution to be protected by a powder shaking device with cyclic powder spreading. However, this technical solution is prone to powder loss during the powder recovery process, and the dropped hot melt powder may return to the thermal transfer film. Utility Model Content
