Dyeing method and dyeing device of gradient eyeglass

Abstract

The invention discloses a dyeing method and a dyeing device of gradient eyeglass. The dyeing method comprises the following steps of: 1, configuring dyeing solution according to the dyeing requirement of present eyeglass, and enabling the dyeing resolution to reach a desired temperature condition; 2, putting the eyeglass into the dyeing resolution, and descending the liquid level of the dyeing solution at the speed of 5-40mm / min; 3, keeping the liquid level of the dyeing resolution when the dyeing of the gradient section of the eyeglass is accomplished; after one dyeing process is completed, resetting the eyeglass, and resetting the liquid level of the dyeing resolution for dyeing of next process. The dyeing device comprises a dyeing groove, a baffle plate, an eyeglass fixing frame, an eyeglass elevating mechanism, a baffle plate elevating mechanism and a control system. Compared with the prior art, the eyeglass does not need to be lifted repeatedly in different sections in one dyeing process, so that the dyeing efficiency is improved; and due to the mode that the liquid level is descended gradually is adopted, the eyeglass can be dyed in gradient in deed, so that the function of good dyeing effect is achieved.

Description

Technical field [0001] The invention relates to a dyeing method and corresponding equipment for a lens, more specifically to a dyeing method and a dyeing equipment for a gradient color lens. Background technique [0002] As one of the current popular lenses, gradient lenses are generally made by thermal dyeing process. For one of the manufacturing processes, please refer to Chinese Invention Patent Publication CN1199176A. The disclosed progressive color lens dip dyeing process is: [0003] ① Immerse the lens in blue dye solution, rinse it in cold water at 4-10℃ after full dyeing for 4-6 seconds, rinse with cold water after 2-3 seconds to remove floating color; [0004] ②Then immerse the lens in green dye solution, and rinse it in cold water at 4-10℃ for 3-5 seconds to remove floating color; [0005] ③Finally, immerse the lens in a brown dye solution, rinse in cold water at 4-10°C after half dyeing for 10 seconds, and rinse in cold water for 4-5 minutes after half dyeing for 2-3 second...

AI Technical Summary

Problems solved by technology

[0013] 1. In the whole dyeing process, the lens needs to be pulled in multiple stages, that is, to achieve up and down movement to change its immersion depth in the dyeing solution; therefore, the above dyeing method can only be applied to small-scale lens dyeing, and the dyeing scale is limited. Low dyeing efficiency;
