Abstract

The invention provides a printed matter oven. The printed matter oven comprises a fan; the fan is arranged in an intake chamber; the intake chamber is provided with an intake port at the bottom and an exhaust port at the bottom; a heating chamber is arranged below the intake chamber; the top of the heating chamber is communicated with the exhaust port of the intake chamber; a heater is arranged in the heating chamber; a drying chamber is arranged below the heating chamber; a wind guide plate is arranged above the drying chamber, and is provided with multiple small holes; a support table for placing printed matters is arranged at the middle part of the drying chamber; and an air outlet is formed in the side wall of the drying chamber above the support table. The printed matter oven largely prolongs the drying time through increasing the power of the fan and the heater, meanwhile, forms proper wind pressure on the surfaces of the printed matters to prevent deformation of the printed matters during accelerating drying through reasonably arranging the height of the wind guide plate and structures on the wind guide plate, and introduces a wind return box for generating hot wind above and below the printed matters so as to greatly improve the drying efficiency and quality.

Description

Printed matter baking oven

Technical field

The present invention relates to a kind of printed matter baking oven, more particularly to a kind of screen process press production solvent-based ink product when institute The baking oven for using, belongs to printed matter technical field.

Background technology

At present, screen process press is in production UV（Ultraviolet light polymerization）During ink product, the quality requirement of product can be met, but When being production solvent-based ink, product can produce the problem of set-off because drying is impermeable, while VOCs（volatile organic compounds）Volatile organic matter index is also significantly larger than the technical standard of country and client.

In recent years, control requirement of the cigarette packet rows industry to sanitary safety index is increasingly tighter, and as negative item, once spot-check It is overproof to VOCs single indexs or overall performane, will directly cancel supplier's qualification.

The content of the invention

In view of in background technology oven of screen printing machine to there is the not thorough paper distortion amount of ink setting big, it is difficult to meet life Product demand, while the also exceeded problem of VOCs indexs, it is an object of the invention to provide a kind of printed matter baking oven, can meet printing The flash baking of product paper, while the requirement of VOCs discharge indexs can also be met.

To achieve these goals, the technical solution used in the present invention is：

A kind of printed matter baking oven, including blower fan, the blower fan are arranged in inlet air plenum, and air inlet is provided with the top of the inlet air plenum Bottom is provided with air outlet, is provided with heating chamber below the inlet air plenum, the air-out of the top of the heating chamber and the inlet air plenum Mouth is connected, and heater is provided with the heating chamber, and drying chamber is provided with below the heating chamber, is set above the drying chamber There is wind deflector, the wind deflector is provided with by several apertures, and the branch for placing printed matter is provided with the middle part of the drying chamber Support platform, is located at the position above the supporting table and is provided with exhaust outlet on the side wall of the drying chamber.

When using, outside fresh air is sucked inlet air plenum by blower fan, subsequently into heating chamber, is become by the heating of heater Hot blast, is directly uniformly blown on printed matter hot blast by wind deflector, enables printed matter flash baking.

Also include that the middle part being arranged on the outside of the exhaust outlet is provided with the air-intaking box of dividing plate, the dividing plate and the supporting table In sustained height and less than the exhaust outlet, positioned at the lower section of the supporting table and positioned at described in the side of the air-intaking box The side wall of drying chamber is provided with return air inlet, the baking of the opposite side positioned at the lower section of the supporting table and positioned at the air-intaking box The side wall of dry chamber is provided with air-out passage.

The wind that will be discharged from exhaust outlet on the wall of drying chamber side by setting air-intaking box introduces the lower section of drying chamber supporting table, There is the presence of hot blast the upper and lower and lower section of printed matter, accelerates drying, improves drying efficiency and effect.

The wind deflector is 3 to 5 centimetres apart from the distance of the supporting table, and the hole diameter on the wind deflector is 3 to 5 Millimeter, and uniform arrangement.

By the height of reasonable arrangement wind deflector so that printed matter surface forms suitable blast, accelerate drying.

The blower fan is axial fan, and the rotating speed of the blower fan is 2800 revs/min, than common 1400 revs/min The rotating speed of blower fan double, the air quantity of increasing, the drying of quickening, it is to avoid printed matter produces Texturized for a long time.

The heater uses 5 to 10 two kilowatts of heating rod.

The supporting table uses corrugated sheet.

Filter layer and discharge detection sensor are provided with the air-out passage.

Another scheme is, also including the in line passage being arranged on the outside of the exhaust outlet, to be provided with the in line passage Filter layer, the end of the in line passage is additionally provided with discharge detection sensor.

Filter layer is set in line passage can absorb volatile organic matter, so that VOCs discharges are reduced, while setting Discharge detection sensor, it is to avoid discharge is not up to standard.

Effect of the invention is as follows：

The printed matter baking oven that the present invention is provided, by the power for increasing blower fan and heater so that drying time has very big Lifting, while the structure on the height and wind deflector that pass through reasonable arrangement wind deflector causes to be formed suitably in printed matter surface Blast, it also avoid printed matter and deformation occurs while accelerating drying, also by introduce air-intaking box so that printed matter up and down all There is hot blast, drying efficiency and quality have very substantially high.
