Description

Technical Field

[0001] The invention relates to the technical field of oiling machines, in particular to an oiling machine for paper surface treatment. Background Art

[0002] The oiling machine is an essential machine for fine post-printing processing of printed products. After UV oiling and glazing, the surface brightness of various packaging decorations and color printed products is significantly improved and the exquisite colors are maintained. The oiling machine is an important equipment for surface finishing and production of packaging products such as cartons and paper boxes. It plays a very important role in improving the surface properties of printed products and improving the wear resistance, stain resistance and water resistance of printed products.

[0003] Prior art patent number CN202320031106.2 discloses a cardboard oiling machine, which first uses the frame plate on the left side of the shell to clean the cardboard, and then uses a suction pump to transport the oil in the oil storage tank to multiple nozzles, and the nozzles evenly spray the oil on the outer wall surface of the cardboard, so as to achieve all-round oiling treatment of the outer wall surface of the cardboard, and there is no need to change the position of the cardboard for oiling, which greatly improves the efficiency of oiling. When the cardboard after oiling passes through the frame plate on the right side of the shell, the hot air sprayed from the air holes on the inner wall of the frame plate dries the cardboard, accelerates the drying speed of the cardboard, and is sucked by a vacuum cleaner, and the air and dust impurities adhering to the surface of the cardboard flow into the annular air cavity through the multiple air holes, and then are transported to the vacuum cleaner through the annular air cavity for storage, so as to facilitate comprehensive cleaning of the cardboard surface and avoid dust impurities affecting the uniformity of the oil. The hot air blower transports hot air to the annular air cavity in the frame plate on the right side of the shell, and the hot air is sprayed through multiple air holes, which can dry the surface of the cardboard after oiling and improve the drying speed of the oil.

[0004] However, it is not convenient to adjust the drying angle of the oiling machine during the drying process. When the oil is brushed too thick or too thin, it is difficult to dry the oil or it is over-baked. In addition, when some coating rollers are rolling on the paper, some impurities will adhere to the surface, which will easily stick to the cardboard during the rolling process. Therefore, it does not meet the existing needs. We have proposed an oiling machine for paper surface treatment. Summary of the invention
