Abstract

The utility model provides an exhaust pipe constant voltage control system suitable for gravure press drying system, touch -sensitive screen, programmable controller, row fan frequency converter, exhaust fan, total exhaust pipe, wind pressure detect mouthful by drawing together, the wind pressure changer is constituteed, touch -sensitive screen and programmable controller number of pass carry out the intercommunication according to the line connection, total exhaust pipe and exhaust fan UNICOM, exhaust fan run -on fan frequency converter arranges fan frequency converter and connects programmable controller, is equipped with the wind pressure in total exhaust pipe and detects the mouth, and the wind pressure detects a mouthful intercommunication wind pressure changer, and wind pressure changer signal output part connects programmable controller. The utility model discloses originally, be applicable to gravure press drying system, automation level of equipment is high, and the operation is simple reliable, can improve safe operation factor, reduce the energy consumption by a wide margin, guarantees regardless of adjusting any air door, and wind pressure in the exhaust pipe is maintain constant all, makes each colour cell wind pressure easily mate.

Description

A kind of exhaust duct control system of invariable pressure being applicable to intaglio press drying system

Technical field

This utility model relates to intaglio press drying system, particularly relates to one and is applicable to intaglio press drying system Airduct control system of invariable pressure.

Background technology

Intaglio press employing Rotary directly prints mode and prints, and forme direct engraving, on plate cylinder, is adopted Ink is given with leaching ink or ink-jetting style.Owing to layer of ink is thick, it is contemplated that ink setting and solvent volatilization, it is necessary to have drying system.

The intaglio printing press sold in the market, relies primarily on operator and manually regulates drying system according to practical experience Running status: manually the regulation new air door of each printing element and return air door reach the size of the most required intake, manually adjust Save the exhaust door of parallel exhaust duct to reach the size of respective exhaust air rate, and make drying oven be in micro-vacuum state.But because of Being multiple spot regulation for air draft, influence each other, between system each point, leeway is relatively big, easily causes drying oven exhaust gas leakage, is difficult to Adjustment, so needing to strengthen exhaust air rate to guarantee that baking oven reduces leakage, then adds this only manually the most repeatedly adjustment with sensation and is One is loaded down with trivial details and be difficult to the thing held, and experience can be absorbed in the predicament adjusting worse and worse not, so production exercise in actual production Make personnel generally will not intense adjustment, in order to meet major part technique air quantity and the improvement of self working environment, the most all keep watch Amount regulates bigger, and again regulates substantially without because product is different, not only adds and adds thermal energy consumption and air draft wind Machine runs power, also increases input cost and run cost that follow-up VOC emission is administered simultaneously.Meanwhile, drying system is each Printing element design temperature must manually set, easily on each colour cell temp controlled meter according to different requirement of every kind of Product Process Specification error occurs, causes product quality accident.

In sum, existing drying system existing problems mainly have: each colour cell blast coupling difficulty, temperature setting easily occur Error, exhaust air rate are excessive, VOC emission too high, follow-up improvement cost is big to add thermal energy consumption.The electric control system of this drying system is just Design to solve the problems referred to above.

Utility model content

In view of this, technical problem to be solved in the utility model is: a kind of automatization level will be provided high, run letter Single reliable, safe operation coefficient can be improved, energy consumption is greatly lowered, reduces discharge amount of exhaust gas and be applicable to intaglio press and be dried and be The exhaust duct control system of invariable pressure of system.

In order to achieve the above object, this utility model adopts the following technical scheme that and realizes:

A kind of exhaust duct control system of invariable pressure being applicable to intaglio press drying system, by including touch screen, programmable control Device processed, exhaust blower converter, exhaust blower, total exhaust duct, blast detection mouth, wind pressure transmitter composition, it is characterised in that: described tactile Touch screen and Programmable Logic Controller to be in communication with each other by data wire connection, described total exhaust duct and exhaust blower UNICOM, exhaust blower Connecting exhaust blower converter, exhaust blower converter connects Programmable Logic Controller, is provided with blast detection mouth in total exhaust duct, and blast is examined Surveying mouth connection wind pressure transmitter, wind pressure transmitter signal output part connects Programmable Logic Controller.

As shown from the above technical solution, compared to existing technology, the beneficial effects of the utility model are:

This utility model is originally applicable to intaglio press drying system, and equipment automatization level is high, runs simple and reliable, energy Improving safe operation coefficient, energy consumption is greatly lowered, it is ensured that no matter regulate any air door, the blast in exhaust duct all remains permanent Fixed, make each colour cell blast be prone to coupling.

Detailed description of the invention

In order to make those skilled in the art can be further understood that feature of the present utility model and technology contents, refer to Lower about detailed description of the present utility model and accompanying drawing.

Refer to shown in Fig. 1, a kind of exhaust duct control system of invariable pressure being applicable to intaglio press drying system, tactile by including Touch screen 1, Programmable Logic Controller 2, exhaust blower converter 3, exhaust blower 4, total exhaust duct 5, blast detection mouth 6, wind pressure transmitter 7 groups Becoming, described touch screen 1 and Programmable Logic Controller 2 are in communication with each other by data wire connection, described total exhaust duct 5 and exhaust blower 4 UNICOMs, exhaust blower 4 connects exhaust blower converter 3, and exhaust blower converter 3 connects Programmable Logic Controller 2, is provided with in total exhaust duct 5 Blast detection mouth 6, blast detection mouth 6 connects wind pressure transmitter 7, and wind pressure transmitter 7 signal output part connects Programmable Logic Controller 2。

But the foregoing is only preferable possible embodiments of the present utility model, and be not used to limit to patent of the present utility model Scope, therefore the equivalent structure change that all utilization this utility model description and accompanying drawing content are made, be the most in like manner included in this practicality In novel scope.
