Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a printing roller cooling device for printing equipment. Background Art

[0002] Printing is graphic communication, which is the technology of batch copying the original contents of text, pictures, photos, anti-counterfeiting manuscripts, etc. through plate making, inking, pressurization and other processes, so that the ink is transferred to the surface of paper, textiles, plastics, leather, PVC, PC and other materials. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. The printing roller is an important component in printing equipment.

[0003] In the whole printing process, due to the adhesion of ink on the printing roller, the printing roller needs to be heated and adhered. If the temperature of the printing roller is too high, it will affect the viscosity and adhesion of the ink, so the printing roller needs to be cooled. The existing printing roller cooling devices are mostly water-cooled or air-cooled. The cooling effect of the existing printing roller cooling devices is general. The cooling device cannot quickly reduce the heat on the surface of the printing roller in a short time. If the cooling time is too long, it will easily affect the working efficiency of the printing roller. To this end, we provide a printing roller cooling device for printing equipment to solve the above problems. Utility Model Content

A No. 2 water pipe 22 is connected to the output end of the water pump 20. The two groups of No. 2 water pipes 22 are respectively connected to the two ends of the printing roller body 5 for fixed-point movement. A refrigeration plate 23 is arranged on the top inner wall of the cooling box 7.

[0025] The cooling plate 23 adopts a semiconductor cooling sheet, through which the cooling plate 23 can cool the coolant stored in the upper layer of the cooling box 7 after use. The partition plate 9 is arranged inside the cooling box 7, and the partition plate 9 can divide the inside of the cooling box 7 into two parts, which are used to store the used and unused coolants in the cooling box 7 respectively. The coolant stored in the upper layer of the cooling box 7 after use can flow to the lower layer of the cooling box 7 for storage through the valve 10. When the water pump 20 is running, since the No. 1 water pipe 21 passes through the lower inner wall of the cooling box 7, the coolant stored in the cooling box 7 The cooling liquid can enter the interior of the water pump 20 through the No. 1 water pipe 21, and then the mechanical energy of the water pump 20 is converted into the kinetic energy of the liquid, which can accelerate the cooling liquid to enter the interior of the printing roller body 5 through the No. 2 water pipe 22. After the cooling liquid circulates once inside the printing roller body 5, the used cooling liquid can flow into the upper space inside the cooling box 7 for storage through the No. 2 water pipe 22, the water pump 20 and the No. 1 water pipe 21 set through the other end of the printing roller body 5, so as to realize the recycling of the cooling liquid, and use the cooling liquid to perform preliminary water cooling on the interior of the printing roller body 5;

When the exhaust fan 16 arranged inside the mounting tube 15 is running, the cold air inside the cooling box 7 can enter the interior of the blowing shell 18 through the No. 1 air duct 14 and the No. 2 air duct 17. The cold air inside the cooling box 7 can be blown toward the printing roller body 5 through the blowing shell 18, thereby realizing the further air cooling of the printing roller body 5 by air cooling.

[0027] like Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a printing roller cooling device for printing equipment;

[0028] A No. 1 motor 2 is arranged on the back of the support frame 1, a connecting shaft 3 is arranged at the output end of the No. 1 motor 2, a No. 1 gear 4 is arranged at the other end of the connecting shaft 3, and a No. 2 gear 6 is arranged on the back of the printing roller body 5, and the No. 2 gear 6 is meshed and connected with the No. 1 gear 4.

The No. 2 gear 6 is arranged on the back of the printing roller body 5. Since the No. 1 gear 4 is meshed with the No. 2 gear 6, when the No. 1 gear 4 rotates, the printing roller body 5 can be driven to rotate inside the support frame 1, which is convenient for cleaning the surface of the printing roller body 5 after use. Through the rotation of the printing roller body 5, the ink can be transferred to the surface of paper, textiles, plastics, leather, PVC, PC and other materials to copy the original content in batches.

When the exhaust fan 16 arranged inside the mounting tube 15 is running, the cold air inside the cooling box 7 can enter the inside of the blowing shell 18 through the No. 1 air duct 14 and the No. 2 air duct 17. The cold air inside the cooling box 7 can be blown to the printing roller body 5 through the blowing shell 18, so that the printing roller body 5 is cooled again by air cooling. The printing roller body 5 is cooled by water cooling and air cooling at the same time, which can effectively improve the working efficiency of the printing roller.

The No. 2 gear 6 is arranged on the back of the printing roller body 5. Since the No. 1 gear 4 is meshed with the No. 2 gear 6, when the No. 1 gear 4 rotates, the printing roller body 5 can be driven to rotate inside the support frame 1, so that the surface of the printing roller body 5 after use can be cleaned.
