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 the technology of batch-copying the original contents of text, pictures, photos, anti-counterfeiting manuscripts, etc. by transferring ink to the surface of paper, textiles, plastics, leather, PVC, PC and other materials through processes such as plate making, inking and pressurization. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. Printing in a broad sense includes pre-press, printing, post-press and various processes and processes related to image and text reproduction. Among them, the printing roller is a key component of the printing equipment.

[0003] However, during the printing process, the temperature of the printing roller is easy to rise. In order to prevent the printing roller from being damaged by excessive temperature, it needs to be cooled. Currently, most printing rollers on the market use the traditional cooling method of blowing air on their surface, but this method is relatively slow when cooling and the efficiency is not high, which affects the printing efficiency. Therefore, it is necessary for us to propose a printing roller cooling device for printing equipment to solve the above problems. Utility Model Content

[0008] Preferably, the connecting shaft is rotatably connected to the support frame via a bearing, the water inlet pipe and the water outlet pipe are movably connected to the printing roller body via a bearing, and a mounting groove matching the circulating water pipe is provided inside the printing roller body.

[0009] Preferably, the water inlet pipe and the water outlet pipe are provided with sealing grooves matching the sealing plates, the sealing columns are rotatably connected to the water inlet pipe and the water outlet pipe via bearings, and the support frame is provided with movable grooves matching the connecting columns.

[0011] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0012] 1. By pressing the connecting column, the connecting column squeezes the telescopic spring to shrink and move, and the connecting column moves to be sleeved with the outer wall of the square column, so that the connecting column and the sealing column are connected and fixed, and then the connecting column is rotated, and the connecting column rotates through the square column to drive the sealing column to rotate, and the sealing column rotates to drive the sealing plate at the bottom to rotate, and the sealing plate rotates to release the sealing protection of the water inlet pipe and the water outlet pipe, so that the water flow inside the circulating water pipe can circulate through the water inlet pipe and the water outlet pipe.

[0013] 2. When the printing roller body is in operation, the printing roller body rotates inside the support frame through the connecting shaft. When the printing roller body is printing, the flowing water inside the circulating water pipe of the outer wall sleeve of the support shaft absorbs the heat generated by the inner wall of the printing roller body, and conducts the heat through the outlet pipe to complete the cooling operation on the surface of the printing roller body. At the same time, the water inlet pipe and the outlet pipe are movably connected with the connecting shaft and the printing roller body through bearings, so that when the printing roller body and the connecting shaft rotate, the positions of the water inlet pipe and the outlet pipe can be kept stationary, which can reduce the damage of the outer walls of the water inlet pipe and the outlet pipe due to distortion and deformation, resulting in reduced cooling effect of the circulating water pipe.

When the printing roller body 201 is printing, the flowing water inside the circulating water pipe 204 of the outer wall sleeve of the support shaft 205 absorbs the heat generated by the inner wall of the printing roller body 201, and conducts the heat through the outlet pipe 203 to complete the cooling operation on the surface of the printing roller body 201. At the same time, the water inlet pipe 202 and the water outlet pipe 203 are movably connected with the connecting shaft 206 and the printing roller body 201 through bearings, so that when the printing roller body 201 and the connecting shaft 206 rotate, the positions of the water inlet pipe 202 and the water outlet pipe 203 can remain unchanged, which can reduce the damage of the outer walls of the water inlet pipe 202 and the water outlet pipe 203 due to distortion and deformation, resulting in a reduction in the cooling effect of the circulating water pipe 204.
