Problems solved by technology

[0005] Due to the unreasonable structural design of the existing ink bottle exhaust device, the sensitivity to ink bottle exhaust is low, and the pressure fluctuation in the ink bottle can only play the role of exhaust when it reaches about 0.2BAR, making the carpet printer When the ink is supplied to the ink bottle during the printing process, the pressure in the ink bottle rises greatly, and it is difficult to achieve the purpose of rapid exhaust, which will cause obvious color changes when the carpet printer prints the pattern, and it is difficult to improve the printing carpet. the quality of

Abstract

The invention relates to a quick exhausting device for an ink bottle, which is mainly applied to an ink bottle of a carpet printer and is used for solving the problem of remarkable color change during printing of patterns with the carpet printer since the structural design of the structure of the conventional exhausting device for an ink bottle is unreasonable and the aim of quickly exhausting cannot be fulfilled easily. The quick exhausting device comprises a valve body, a valve cover and a membrane, wherein an air outlet, an ink bottle air outlet, a pressure relief pipe and a membrane cavity are formed / arranged in the valve body; the membrane is arranged on the membrane cavity; an air inlet is formed in the valve cover; and the valve cover is fixed on the valve body. The quick exhausting device is characterized by further comprising a valve core, wherein the valve core is fixed in the pressure relief pipe of the valve body; an air leakage channel exists between the valve core and the pressure relief pipe; an exhaust channel is formed in the valve core; and the valve core is matched with the membrane. The quick exhausting device has a reasonable structural design, reliable performance and high sensitivity, a quick exhausting function can be realized, and remarkable change of a printing color before and after ink supply of the carpet printer is prevented.

Description

technical field [0001] The invention relates to a quick exhaust device, in particular to an ink bottle quick exhaust device, which is mainly used in the ink bottle of a carpet printer. When the carpet printer supplies ink to the ink bottle during the printing process, the ink bottle will be damaged The pressure in the ink bottle rises, and the pressure in the ink bottle can be quickly released through the quick exhaust device of the ink bottle. Background technique [0002] The carpet printer needs to supply ink to the ink bottle during the printing process. When the carpet printer supplies ink to the ink bottle during the printing process, the pressure in the ink bottle will increase. If the pressure in the ink bottle is not released quickly, It will cause obvious color changes in the pattern printed by the printer, which will greatly affect the quality of the printed carpet and reduce the quality of the printed carpet. This requires a quick exhaust device to be installed i...
