[0021] The present invention provides a printing roller cooling device for printing equipment that is convenient for ink cleaning, and has the following beneficial effects:

[0022] The printing device uses a printing roller cooling device that is easy to clean ink. Through the heat dissipation component and the printing roller component, when the printing roller is cooled and radiated, the second reduction motor is started, and the second reduction motor drives the fan blades to rotate through the output rod. When the fan blades rotate, they draw in external air, and part of the air passes through the fan housing and the three-way ventilation duct into the exhaust duct and is sprayed out from a plurality of nozzles on the exhaust duct, and part of the air passes through the three-way ventilation duct into the rotary joint, and then the air passes through the rotary tube and the mounting tube into the printing roller body, and then the air is discharged from the mounting tube at the other end of the printing roller body, so that the surface of the printing roller body and the inside of the printing roller body can be cooled, and the heat dissipation effect and heat dissipation efficiency when the printing roller body is cooled can be improved.

[0023] The printing equipment uses a printing roller cooling device that is easy to clean ink. Through the heat dissipation component and the printing roller component, when the printing roller is cooled and radiated, the second reduction motor is started, and the second reduction motor drives the spiral blades and the fan blades to rotate through the output rod. The spiral blades rotate to extract liquid in the liquid storage tank and send the liquid into the three-way water pipe. Then the liquid enters the spiral water pipe through the second drainage pipe, the connecting pipe, the second telescopic hose and the first butt joint pipe. The liquid absorbs the heat on the printing roller body. Then the liquid enters the liquid storage tank through the first butt joint pipe, the second telescopic hose, the connecting pipe and the water guide pipe at the other end of the spiral water pipe. In combination with the fan blades, a double heat dissipation method is used to dissipate the heat of the printing roller body, thereby improving the heat dissipation effect and heat dissipation efficiency when the printing roller body is cooled.

[0024] The printing equipment uses a printing roller cooling device that is convenient for cleaning ink. Through the heat dissipation component and the cleaning component, when the printing roller needs to be cleaned, the first electric push rod, the first reduction motor and the second reduction motor are started. The first electric push rod is started to drive the L-shaped cover to rotate forward through the second rotating block and the L-shaped plate, so that the cleaning brush plate contacts the surface of the printing roller body. Then the first reduction motor is started to drive the printing roller assembly to rotate through the second gear, the first gear, the rotating tube and the mounting component. The second reduction motor is started to drive the spiral blade to rotate through the output rod, and the second electromagnetic valve is opened. Liquid enters the water spray pipe through the three-way water pipe, the first drainage pipe, the first telescopic hose and the connecting water pipe, and is sprayed from a plurality of nozzles at the front end of the water spray pipe to wash the surface of the printing roller body. The brush on the cleaning brush plate cleans the surface of the printing roller body. When cleaning the ink on the printing roller body, the printing roller body can be automatically cleaned, thereby improving the convenience of cleaning the printing roller and improving the practicality of the equipment.

[0025] The printing equipment uses a printing roller cooling device that is easy to clean ink. Through the cleaning component, when the printing roller is cleaned, the water collecting tank can collect the sewage generated when the printing roller is cleaned. When the cleaning is completed, the water collecting tank can be pulled out from the L-shaped cover. After the sewage is treated, the treated liquid can be injected into the liquid storage tank through the water inlet valve at the rear end of the liquid storage tank to reduce the waste of water resources.

[0026] The printing equipment uses a printing roller cooling device that is easy to clean ink. Through the installation component, the docking component and the printing roller component, when the printing roller component needs to be disassembled, the second electric push rod is started to drive the first docking tube and the sealing ring to move and separate from the second docking tubes at both ends of the spiral water pipe, and then the screws that install the first arc-shaped mounting plate and the second arc-shaped mounting plate are removed, and then the second arc-shaped mounting plate and the printing roller component are removed. When installing the printing roller component, the two mounting tubes are installed with the two mounting components, and then the second electric push rod is started to drive the first docking tube and the sealing ring to move and dock with the second docking tubes at both ends of the spiral water pipe. The printing roller component and the equipment can be easily disassembled and installed, thereby improving the convenience of the equipment when used. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] like Figures 1 to 12As shown, firstly, the first reduction motor 105 is started, and the printing roller assembly 6 is driven to rotate through the second gear 106, the first gear 103, the rotating tube 102 and the mounting assembly 4, then the second reduction motor 206 and the semiconductor cooling sheet are started, and the first solenoid valve 2017 is opened at the same time, and the second reduction motor 206 drives the spiral blade 208 and the fan blade 209 to rotate through the output rod 207, and the spiral blade 208 sends the liquid in the liquid storage tank 201 into the three-way water pipe 2016 through the outlet pipe 203, and then the liquid passes through the second drain pipe 2020, the connecting pipe 507, the second telescopic hose 506 and the first butt joint 504 into the spiral water pipe 603, and the liquid absorbs the heat on the printing roller body 602, and then the liquid passes through the spiral water pipe 603 The first butt joint 504, the second telescopic hose 506, the connecting pipe 507 and the water guide pipe 202 at the other end enter the liquid storage tank 201, and the semiconductor refrigeration plate cools the liquid in the liquid storage tank 201. At the same time, the fan blades 209 rotate to draw air from the outside. Part of the air passes through the fan housing 2011 and the three ventilation pipes 2012 into the exhaust pipe 2013, and is sprayed out from a number of nozzles on the exhaust pipe 2013 to cool the surface of the printing roller body 602. Part of the air passes through the three ventilation pipes 2012 and enters the rotary joint 2014. Then the air passes through the rotating tube 102 and the mounting pipe 601 and enters the printing roller body 602, thereby increasing the air circulation speed inside the printing roller body 602. Then the air is discharged from the mounting pipe 601 at the other end of the printing roller body 602. 1 is discharged. When the surface of the printing roller body 602 needs to be cleaned, the first electric push rod 303 is then started, and the L-shaped cover 305 is driven to rotate forward through the second rotating block 304 and the L-shaped plate 301, so that the cleaning brush plate 307 contacts the surface of the printing roller body 602. Then the first solenoid valve 2017 is closed and the second solenoid valve 2018 is opened. The liquid enters the water spray pipe 308 through the three-way water pipe 2016, the first drainage pipe 2019, the first telescopic hose 3010 and the connecting water pipe 309, and is sprayed from the plurality of nozzles at the front end of the water spray pipe 308 to wash the surface of the printing roller body 602. The brush on the cleaning brush plate 307 cleans the surface of the printing roller body 602. When the cleaning is completed, the second solenoid valve 2018 is closed and the first electric push rod 303 is opened. The magnetic valve 2017 is used to pull the water collecting box 306 out of the L-shaped cover 305 through the handle at the rear end of the water collecting box 306 to clean the sewage in the water collecting box 306. Then, the first electric push rod 303 is closed and started to push the L-shaped cover 305 to rotate backward. The air sprayed from the nozzles on the exhaust pipe 2013 can dry the surface of the printing roller body 602. When it is necessary to disassemble the printing roller assembly 6, the first electromagnetic valve 2017, the first reduction motor 105 and the second reduction motor 206 are closed, and then the second electric push rod 502 is started to drive the first butt joint pipe 504 and the sealing ring 505 to move and separate from the second butt joint pipe 605 at both ends of the spiral water pipe 603. Then, the screws that install the first arc-shaped mounting plate 401 and the second arc-shaped mounting plate 402 are removed.Remove the second arc-shaped mounting plate 402 and the printing roller assembly 6.
