Description

Technical Field

[0001] The present application relates to the technical field of silicone transfer, and in particular to a painted silicone transfer device. Background Art

[0002] Daily utensils, handicrafts, and artworks made by applying lacquer on the surface of various objects are generally called "lacquerware". Raw lacquer is a natural liquid extracted from lacquer trees. It is mainly composed of lacquer phenol, lacquerase, gum and water. Using it as a coating has special functions such as moisture resistance, high temperature resistance, and corrosion resistance. Different colors of paint can also be formulated, which is dazzling.

[0003] Surface printing further improves the ornamental value. Among them, a transfer device is usually used for surface printing, such as a printing machine for paper packaging box production with announcement number CN208978438U, including a belt conveyor, a fixed plate is provided on the front surface of the belt conveyor, a U-shaped plate is provided on the front side of the upper surface of the fixed plate, the end of the U-shaped plate away from the fixed plate is connected to the rear side of the upper surface of the belt conveyor, a screw is provided in the middle of the U-shaped plate, and the side surfaces of both ends of the screw are rotatably connected to the U-shaped plate through bearings, a stepper motor is provided on the front surface of the U-shaped plate, and the output shaft of the stepper motor passes through the U-shaped plate and is connected to the end of the screw, a movable block is provided in the middle of the U-shaped plate, and the screw passes through the front surface of the movable block. The printing machine for paper packaging box production has a firm structure, is stable and durable, and during printing, the rubber scraper can scrape away excess printing liquid on the stainless steel template without making the paper packaging box wet, which brings convenience to use, and the silicone transfer head can improve printing quality, reduce production costs, and improve work efficiency.

[0004] However, the above-mentioned prior art still has some defects in paint transfer: 1. The above-mentioned prior art is driven by a stepper motor and an electric telescopic rod, and the printing liquid on the stainless steel template is printed on the packaging box through a silicone transfer head. However, in this process, the silicone transfer head needs to move a long distance. When a large amount of printing is required, the movement of the silicone transfer head will waste a lot of time, resulting in a waste of time cost, and there is still room for improvement in work efficiency.

[0005] 2. The above-mentioned prior art replenishes the printing liquid by rolling the printing roller back and forth on the stainless steel template. However, during the continuous printing process, the printing liquid in the printing roller will be consumed as printing occurs, which may cause the printing liquid in the printing roller to be uneven. At this time, the printing effect deteriorates, and it is necessary to stop the machine to manually replenish the printing liquid or replace the printing roller. There are still defects during continuous printing.

[0006] Based on this, and in accordance with the above-mentioned viewpoints, the existing technology for paint transfer still has room for improvement. Utility Model Content
