Description

Technical Field

[0001] The utility model belongs to the technical field of UV glue processing, in particular to a viscosity regulating device for UV glue processing. Background Art

[0002] At present, UV glue is also called photosensitive glue and ultraviolet light curing glue. Shadowless glue is a type of adhesive that must be cured by ultraviolet light. UV glue is needed in the manufacturing process of optical film, and the UV glue is required to reach an appropriate viscosity, because too high viscosity or too low viscosity will affect the quality of the optical film. Generally, solvents are added to the UV glue to adjust the viscosity of the UV glue. The adjustment process requires the use of an adjustment device. In order to ensure the accuracy of the adjustment, the existing adjustment device cleans the debris remaining in the adjustment tank through the installed cleaning component after use, so as to ensure that the subsequent adjustment is more accurate and extend the service life of the device. Although the cleaning effect can be achieved, the debris cleaned after the UV glue dries may cause the glue discharge port to be blocked, requiring manual auxiliary cleaning, making the overall cleaning operation time-consuming and labor-intensive.

[0003] After searching, the Chinese patent document (authorization announcement number CN218358738U) is a viscosity adjustment device for UV glue processing. A rotating tube is fixedly installed vertically through the middle end of the sealing cover. A rotating rod is vertically installed inside the middle end of the rotating tube through a bearing. The outer surface of the rotating rod is fixedly sleeved with a transmission bevel gear. The technical solution of the utility model is to mesh the transmission bevel gear and the follower bevel gear, so that the operator only needs to rotate the rotating rod by hand, and then combined with the structural effect of the rotating screw and the movable sleeve, the movable sleeve can be moved horizontally along the outer side of the rotating screw under the transmission effect of the push rod. Although this patent can achieve the cleaning effect, the debris cleaned after the UV glue dries may cause the glue discharge port to be blocked, requiring manual auxiliary cleaning, making the overall cleaning operation more time-consuming and labor-intensive.
