Problems solved by technology
[0003] The traditional drying oven is to face the printing surface for drying. Due to the limitation of the oven structure, the wind speed blown out by the tuyere nozzle is low and the air intake is small, resulting in low drying efficiency; and the traditional drying oven only has an explosion-proof cover on the top of the movable box, which has poor safety performance. Therefore, the structure of the oven needs to be optimized

The invention discloses a novel drying box device. The novel drying box device comprises a movable box body and a fixed box body. The movable box body is provided with an air inlet a and an air outleta. The fixed box body is provided with an air inlet b and an air outlet b which is opposite to the air outlet a. An explosion-proof cover a is arranged at the top of the movable box body. An explosion-proof cover b is arranged on a side plate of the side, far away from the air outlet b, of the fixed box body. The novel drying box device is provided with the explosion-proof covers, the explosion-proof covers can be opened when gas pressure inside each box body reaches a certain value, gases in the box bodies can overflow from explosion-proof through holes, and safe operation in the productionprocess is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of printing drying equipment, and in particular relates to a novel drying box device. Background technique [0002] The gravure printing machine is mainly composed of feeding, traction, drying system, receiving and other parts. The drying system uses electricity, steam, heat-conducting oil or natural hot gas to heat the air, and blows the hot air heated to the set temperature into the inner cavity of the oven through an external fan, and evenly blows it on the ink layer of the material film by the air nozzle on the inner cavity. Above, the solvent (or moisture) in the ink evaporates after being subjected to wind pressure and heat absorption, and then the hot air containing solvent or moisture is discharged through the side air outlet of the oven, so as to realize the drying of the printing ink. [0003] The traditional drying oven is to face the printing surface for drying. Due to the limitation of the oven...
