Description

Technical Field

[0001] The utility model relates to the technical field of offset printing machines, specifically an ultrasonic atomization wetting device for offset printing machines. Background Art

[0002] An offset printing machine is a type of lithographic printing machine. During printing, the printed graphics and texts are first printed from the printing plate onto the rubber cylinder, and then transferred from the rubber cylinder to the paper. To improve the printing quality on the printed paper, a wetting device is usually used to wet the paper during the printing process of the offset printing machine cylinder, making the paper color more vivid. With the development of modern technology, an ultrasonic atomization mechanism is gradually used for atomizing and spraying wetting on the wetting device of the offset printing machine, making the wetting effect better.

[0003] However, when the existing ultrasonic atomization wetting device wets the printing area during the operation of the offset printing machine, the atomized wetting liquid fails to fully act on the wetting of the paper. Some water vapor will float above the printing area, resulting in excessive humidity in this area. The later printed paper is prone to excessive wetting, which in turn leads to blurred printing ink marks and cannot be used. At the same time, it also causes waste of resources. In response to this, this design proposal presents an ultrasonic atomization wetting device for offset printing machines. Summary of the Utility Model

[0004] To solve the above problems, the purpose of the utility model is to provide an ultrasonic atomization wetting device for offset printing machines to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model proposes an ultrasonic atomization wetting device for offset printing machines, which includes a transmission base, a protective cover, a circulation mechanism installed outside the protective cover, and an ultrasonic atomization wetting mechanism installed inside;

[0006] The circulation mechanism includes air boxes installed on both sides of the protective cover. A plurality of air intake slots are equally spaced on both sides of the inner wall of the protective cover, and the inner walls of each air intake slot are respectively communicated with the interiors of the two air boxes. A plurality of air extraction fans are equally spaced inside the two air boxes. The tops of the two air boxes are respectively penetrated by a first connecting pipe. A liquid storage tank is installed on one side of the top of the protective cover. A branch connecting pipe is penetrated on one side of the liquid storage tank, and one ends of the two first connecting pipes are respectively communicated with the interior of the branch connecting pipe. Dust-proof nets are fixedly provided on the inner walls of the two air boxes at the outer edges of each air extraction fan.

[0007] In one example, the ultrasonic atomization wetting mechanism includes a water extraction pump installed on the other side of the top of the protective cover. The output end of the water extraction pump is connected to a second connecting pipe, and one end of the second connecting pipe is penetrated and connected to the top of the liquid storage tank.

[0008] In one example, an ultrasonic atomizer is installed at the upper end of the inner wall of the protective cover, and the ultrasonic atomizer passes through the outer wall of the protective cover and is connected to a water pump. A sprayer is installed at the bottom of the ultrasonic atomizer.

[0009] In one example, a liquid inlet groove is provided on one side of the top of the liquid storage tank. A clamping groove is provided on one side of the inner wall of the liquid inlet groove, and a sealing cover is inserted through the inner wall of the liquid inlet groove.

[0010] In one example, a clamping strip is fixedly provided at one end of the sealing cover, and the outer wall of the clamping strip is inserted and connected to the inner wall of the clamping groove. A transmission roller is rotatably provided at one end of the inner wall of the protective cover, and one end of the transmission roller passes through the outer wall on one side of the protective cover and is connected to a motor.

[0011] In one example, a control panel is fixedly provided on one side of the transmission base, and the water pump, the ultrasonic atomizer and the motor are all electrically connected to an external power supply through the control panel.

[0012] The offset press ultrasonic atomization wetting device proposed by the present utility model can bring the following beneficial effects:

[0013] For the offset press ultrasonic atomization wetting device, the air extraction fan on the circulation mechanism operates, inhales the atomized water vapor that has not been absorbed by the printed paper through the air inlet groove into the air box, then transmits it to the first connecting pipe by the air box, and then uniformly introduces it into the liquid storage tank through the branch connecting pipe, so that it is pumped into the ultrasonic atomizer again through the air extraction pump and the second connecting pipe to be atomized and continue to be used for wetting. This design prevents the water vapor from accumulating and causing the ink on the printed paper to be blurred, reduces resource waste at the same time, and improves the practicability of the device.

A sub - connecting pipe 306 is penetrated on one side of the liquid storage tank 305, and one ends of the two first connecting pipes 304 are respectively communicated with the interior of the sub - connecting pipe 306. Dust - proof nets 307 are fixedly arranged at the outer edges of each exhaust fan 303 on the inner walls of the two bellows 301 respectively, and the dust - proof nets 307 play a dust - proof role when the exhaust fans 303 in the circulation mechanism 3 are running;

[0024] Furthermore, the ultrasonic atomization and humidification mechanism 4 includes a water pump 401 installed on the other side of the top of the protective cover 2. The output end of the water pump 401 is connected to a second connecting pipe 402, and one end of the second connecting pipe 402 is inserted and connected to the top of the liquid storage tank 305.

[0025] An ultrasonic atomizer 403 is installed at the upper end of the inner wall of the protective cover 2, and the ultrasonic atomizer 403 passes through the outer wall of the protective cover 2 and is connected to the water pump 401. A sprayer 404 is installed at the bottom of the ultrasonic atomizer 403, and the sprayer 404 is arc - shaped to expand the range of atomization and humidification;

[0026] Furthermore, a liquid inlet groove 5 is opened on one side of the top of the liquid storage tank 305, a card groove 6 is opened on one side of the inner wall of the liquid inlet groove 5, and a sealing cover 7 is inserted through the inner wall of the liquid inlet groove 5. When the sealing cover 7 is closed, the liquid inlet groove 5 can be sealed to prevent dust from entering and causing clogging of structures such as the sprayer 404.

[0027] A clamping strip 8 is fixedly provided at one end of the sealing cover 7, and the outer wall of the clamping strip 8 is interlaced and connected with the inner wall of the clamping slot 6.
