Description

Technical Field

[0001] The utility model belongs to the technical field of laminating equipment, and particularly relates to an imprinting and laminating mechanism for wrapping paper and stickers. Background Art

[0002] The laminator is mainly used to heat and press a sticky material and a material to be laminated to achieve the degree of sticking and bonding. For example, for packaging boxes, wrapping paper, etc., after printing beautiful patterns on corrugated cardboard and paper shells, a layer of sticker needs to be covered on the outer surface to play a role in beautification, waterproofing and strengthening the strength of the wrapping paper. The existing laminating equipment generally includes a conveying device for placing the paper shell, a rewinding device for placing the sticky sticker, and a laminating mechanism. However, the existing laminating mechanism directly heats the laminating roller, and the temperature is not easy to control. If the temperature is too high, it is easy to damage the sticker, and bubbles are easily generated during the laminating process, affecting the laminating effect. Content of the Utility Model

The laminating roller is rotationally connected to the fixed block through a first rotating shaft. A first motor is fixedly arranged on one of the fixed blocks, and the output end of the first motor is connected to the first rotating shaft. A heating box is arranged on one of the fixed frames. A heating cavity is formed inside the laminating roller. A sealing block is rotationally arranged on one side of the laminating roller. A first connecting pipe is connected to the heating box, and the other end of the first connecting pipe penetrates through the sealing block and extends into the heating cavity. A pressure relief valve is arranged on the other side of the laminating roller; a pressing plate is arranged on the side of the laminating roller away from the conveying roller, and both ends of the pressing plate are fixedly connected to the fixed block.
