Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to the technical field of drying mechanisms. Background Art

[0002] A printing press is a machine for printing text and images. Its working principle is: first the text and image to be printed are made into a printing plate and installed on the printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate.

[0003] The drying efficiency of the drying mechanism of the existing printing press is low, and the volatile ink solvent cannot be recovered. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide a drying mechanism for a printing press, which can solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model proposes a drying mechanism of a printing machine, including a conveyor belt, a drying box body is provided on the conveyor belt, a drying chamber is provided in the drying box body, an upper drying rack is provided in the drying chamber, an upper heating tube is provided on the upper drying rack, a lower drying rack is provided in the conveyor belt, a lower heating tube is provided on the lower drying rack, an exhaust port is provided on the side of the drying box body, an exhaust fan is provided on the exhaust port, the exhaust fan is connected to an exhaust pipe, a cooling jacket is provided on the outer side of the exhaust pipe, and the exhaust pipe is connected to a recovery box.

[0006] Preferably, a spiral cooling pipe is provided in the cooling jacket, and the spiral cooling water pipe is connected to a cooling circulation device.

[0007] Preferably, the upper drying rack is connected to a lifting motor.

[0008] Preferably, the heating temperature of the upper heating tube is greater than the heating temperature of the lower heating tube.

[0009] Preferably, a cooling roller is provided in the conveyor belt, and the cooling roller is located in front of the drying box.

[0010] The beneficial effects of the utility model are as follows: the utility model dries both sides of the workpiece by arranging heating pipes on the upper and lower sides, thereby improving the drying efficiency; an exhaust port is arranged on the side of the drying box body, so that the volatilization can be easily extracted in time to ensure the drying effect; the exhaust pipe is cooled to condense the solvent and flow into the recovery box, which is convenient for the recycling of the solvent and more environmentally friendly.

[0011] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
