Background

UV ink can be quickly cured by UV illumination after being printed, so that the UV ink is popular in the market. Chinese patent document CN108556475A discloses "a UV ink printed layer curing and drying device" in 2018, 9/21, which includes a curing and drying device base, wherein a support station leg is disposed at the bottom of the curing and drying device base, a drying fixing cover is disposed at the top of the curing and drying device base, an equipment protecting cover is disposed between the support station legs, rotating shafts are disposed at two ends of an inner cavity of the curing and drying device base, a conveying belt is disposed on the rotating shafts, a first transmission shaft is connected to one end of the rotating shafts, a transmission case is connected to one end of the transmission shafts, a second transmission shaft is connected to one end of the transmission case, electrically controlled valves are disposed at two ends of the drying fixing cover, a movable cover plate is disposed at the top of the drying fixing cover, an air exhaust window is disposed on the movable cover plate, and a dustproof filter box is designed to prevent dust, the air filter box of design absorbs the volatile printing ink in the curing and drying process, prevents to cause the influence to the surrounding environment. Generally, a relatively independent printing unit is required to be used for each color in a printing machine, the printing unit comprises a UV lamp, printing materials such as paper and the like, the printing materials enter one printing unit to complete the printing of one color, the printing materials are immediately subjected to illumination curing, and the cured printing materials immediately flow to the next printing unit to perform the printing of the next color until all the colors are printed and cured. Therefore, in this type of conventional structure, an air suction opening is installed near the UV lamp of each printing unit, and the air suction opening is connected to a general air suction fan through an independent air suction pipeline. The exhaust fan is operated continuously to exhaust the waste gas from each exhaust port. For general printing requirements, 4-color printing is the most, and the requirement of more than 4 colors is not much, but in order to meet the requirement of printing colors, the printing machine is generally provided with more than 4 printing units, such as brands of Heidelberg, Roland, Xiaosen and the like, and the mainstream product is an 8-color printing machine, namely comprising 8 printing units. The higher the printing machine is, the more printing units are, the more air suction pipelines are, the higher the power requirement of the exhaust fan is, and the larger the energy consumption, the purchase cost and the occupied space of equipment are. In most printing operations, only 4 necessary printing units are used, only the air suction pipelines of the 4 printing units are effective air suction, and the corresponding air suction pipelines still suck air even if other unnecessary printing units do not work, so that the air suction amount and the energy consumption of the exhaust fan are occupied, but ineffective air suction is realized. It is this problem that the present application seeks to address.

Disclosure of Invention

Based on the above problem, the utility model provides an energy-conserving integrated air current controlgear of total-branch formula can use the air exhauster of less power to realize all having the advantage on energy consumption, acquisition cost and equipment occupation space to the convulsions demand of more printing unit.

In order to realize the purpose of the invention, the utility model adopts the following technical scheme: a total-divided energy-saving integrated airflow control device comprises a total exhaust fan and a plurality of printing units, wherein each printing unit comprises N necessary printing units and at least 2 unnecessary printing units; each printing unit is internally provided with an air exhaust pipeline, a UV lamp, a central controller and a centralized air exhaust box; the downstream end of each air suction pipeline is communicated to the concentrated air suction box; the centralized air pumping box is a sealed space, and the downstream end of the centralized air pumping box is connected to the main exhaust fan; each exhaust pipeline is provided with an electromagnetic valve, each electromagnetic valve is in signal connection with a central controller, and the opening and closing of the electromagnetic valve are synchronous with the opening and closing of the UV lamp beside the exhaust pipeline; the main exhaust fan is in signal connection with the central controller; the exhaust volume of each exhaust pipeline is X, the exhaust volume of the total exhaust fan is Y, and Y is more than or equal to X X (N + 1).

The total-split energy-saving integrated airflow control equipment designed by the scheme comprises a plurality of printing units, wherein the printing units are divided into necessary printing units and unnecessary printing units according to the condition whether the printing units are commonly used or not, the necessary printing units are generally 4, and the unnecessary printing units are generally 2 or more according to the current market requirements. Every printing unit all includes the UV lamp, just is provided with the suction opening beside the UV lamp, and suction opening intercommunication suction line installs the solenoid valve on the suction line, and all suction line are finally all leading-in concentrated suction box. The centralized air extracting box is a sealed box body, and air flows extracted by all air extracting pipelines are collected to the box body. The concentrated wind pumping box is provided with only one downstream opening which is communicated with the main exhaust fan, and the gas in the concentrated wind pumping box is discharged through the operation of the main exhaust fan. In addition, a central controller is adopted for carrying out centralized control on the opening and closing of each electromagnetic valve and the starting and stopping of the main exhaust fan. The central controller is connected with each electromagnetic valve and the main exhaust fan through signals, and can be used for wired signal transmission or wireless signal transmission. If the central controller also integrates the power and electricity control function, the circuits of the solenoid valves and the main exhaust fan can also be connected to the central controller. The opening and closing of the electromagnetic valve are synchronous with the opening and closing of the UV lamp beside the exhaust pipeline, so that the opening and closing functions of the UV lamp can be integrated into a central controller to reduce the number of devices, accelerate the reaction speed and improve the integration level. And taking the exhaust volume of each exhaust pipeline as X, taking the exhaust volume of the total exhaust fan as Y, wherein Y is more than or equal to X X (N +1), namely the power of the total exhaust fan completely covers the exhaust requirements of the exhaust pipelines of all necessary printing units, and at least a margin is reserved to meet the exhaust requirements of the exhaust pipelines of at least 1 printing unit. When the automatic exhaust fan is used, as long as a UV lamp of a certain necessary printing unit is started, the total exhaust fan can be synchronously triggered to start, and the exhaust volume generated after starting is enough to meet the exhaust requirements of exhaust pipelines of all necessary printing units; and meanwhile, the electromagnetic valves are synchronously opened and are arranged on the air exhaust pipelines of the printing unit. Therefore, even if the necessary printing units are not all used, the exhaust gas of the used necessary printing units can be extracted at a high negative pressure. When a certain unnecessary printing unit is used, the UV lamp of the unnecessary printing unit is turned on, the electromagnetic valve arranged on the air exhaust pipeline of the printing unit is also synchronously turned on, and waste gas of the unnecessary printing unit can be well extracted. And other unnecessary printing units not used, the UV light lamp is closed all the time, the electromagnetic valve arranged on the exhaust pipeline is also closed all the time, the exhaust pipeline is cut off, and the negative pressure formed by the total exhaust fan is kept to only generate an effect aiming at the printing unit in a use state, so that the energy consumption and the acquisition cost are effectively saved, and the occupied space of the equipment is reduced.

Preferably, Y = X × (N + 1). Considering that the probability of operating 2 or more unnecessary printing units simultaneously is very low, it is preferable to fix the air suction efficiency of the total air suction fan to the requirement of satisfying the number of necessary printing units +1, further reducing the excessive energy consumption and the cost and volume problems caused thereby.

Preferably, the solenoid valve is normally closed. The electromagnetic valve is normally closed, and particularly the electromagnetic valve arranged in the exhaust pipeline in the unnecessary printing unit is normally closed, so that the electric energy can be effectively saved.

4. when a non-essential printing unit selects to operate, the UV lamp in the non-essential printing unit is started;

5. when the UV lamp in the unnecessary printing unit is started, the electromagnetic valve arranged on the exhaust pipeline of the unnecessary printing unit is synchronously opened;

6. when the unnecessary printing unit stops running, the UV lamp in the unnecessary printing unit stops;

7. when the UV lamp in the unnecessary printing unit stops, the electromagnetic valve arranged on the exhaust pipeline of the unnecessary printing unit is synchronously closed;

8. when all the necessary printing units and the unnecessary printing units stop operating, all the corresponding UV lamps are closed;

9. when all UV lamps were all closed, the solenoid valve that corresponds all closed, and total air exhauster is closed in step.

The scheme specifically provides a using method of the total-separated energy-saving integrated airflow control equipment, which comprises the operation states of starting operation of a printing unit, starting a corresponding UV lamp, synchronously opening an electromagnetic valve, synchronously starting a total exhaust fan, selecting an unnecessary printing unit to start operation, starting a corresponding UV lamp, synchronously opening an electromagnetic valve, stopping operation of an unnecessary printing unit, stopping a corresponding UV lamp, synchronously closing an electromagnetic valve, stopping operation of all printing units, closing all UV lamps, closing all electromagnetic valves, synchronously closing the total exhaust fan and the like. The control of these functions is accomplished by a central controller, either manually or programmed to operate in a fully automatic manner.
