Description
Technical field
The utility model relates to a kind of drying plant, particularly a kind of printing drying plant that is used for metallic article.
Background technology
Metal is as stock, and generally with serigraphy or offset printing, metallic article belongs to durable goods, and decorative surface requires higher, more durable, and is higher to the requirement of printing quality.Metal is as a special printable fabric, and surface strength is good, and unlike the same plucking dry linting of paper, size deformation is relatively stable, does not receive the influence of printing environment and technology, but because of characteristics such as metal material do not absorb water, various printing bad phenomenon takes place easily also.Adopt the heating, drying method after the printing of common metal goods, make printing ink drying quickly, so that follow-up processed; At present, the printing drying plant of metallic article is employed in drying chamber top more and establishes heating tube; Workpiece conveyor is located at the heating tube below, after metallic article is completed for printing, is placed on the multilayer pallet; Get into drying chamber through conveyer belt, the upper workpiece bake out temperature near electrothermal tube is high like this, and low away from the lower workpiece bake out temperature of electrothermal tube; The workpiece that bake out temperature is high can be because the undue high temperature drying of some printing-inks causes the embrittlement of printing ink China ink layer dry and cracked; And reason such as the low workpiece Yin Wendu of bake out temperature crosses low and drying time is not enough causes very easily deinking and stack the sticking China ink of back reverse side trace etc. to occur bad of trace.Too high for preventing bake out temperature, need turn down bake out temperature, so just need the time of lengthening oven dry, thereby reduced the productivity ratio of equipment.
Summary of the invention
The utility model provides a kind of controlled printing drying plant that is used for metallic article that improves equipment productivity again of drying chamber temperature equalization that makes for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of printing drying plant that is used for metallic article; Comprise heater, drying chamber and the conveyer belt through drying chamber; Also comprise pressure fan, circulating fan, hot blast chamber, control valve, temperature controller and controller; Two ends, said hot blast chamber are connected with the air outlet of said pressure fan and the air outlet of said circulating fan respectively; Be provided with return air inlet and a plurality of air outlet between said hot blast chamber and the said drying chamber, said air outlet is provided with control valve, and said return air inlet links to each other with the air inlet of said circulating fan; Said heater is positioned at the junction of the air outlet of said hot blast chamber and said pressure fan; Said temperature controller detects the temperature in the drying chamber, and outputs signal to said controller, the work of said controller output signal control heater, control valve, pressure fan and circulating fan.
The utility model can also adopt following technical scheme:
Said pressure fan is the frequency conversion pressure fan.
Said circulating fan is the frequency conversion circulating fan.
The air inlet place of said pressure fan is provided with filter.
Said heater is the electric heating tube heater.
Advantage and the good effect that the utlity model has are: the hot-air that said drying chamber is discharged is delivered to the circular flow of hot blast chamber through return air inlet; Make each position flowing and temperature equalization in the drying chamber because of hot-air; Hot-air flows and has accelerated the rate of drying of metallic article print surface simultaneously; And hot-air obtains recycle, has reduced the loss of heat, and is not only energy-conservation but also improved equipment productivity; Temperature controller is set detects the oven dry indoor temperature; And give controller with the signal feedback of temperature, by the work of controller coordinate control heater, control valve, pressure fan and circulating fan, the drying chamber temperature is remained in the normal temperature scope; Both prevented undue high temperature drying; Cause the embrittlement of printing ink China ink layer dry and cracked, prevent again that temperature is low excessively to cause deinking etc. bad, improved the qualification rate of metallic article print product.
