Quick-opening device of airflow dyeing machine

Abstract

The invention relates to a quick-opening device of an airflow dyeing machine, which comprises a manhole flange and a manhole cover, wherein the manhole flange is hinged with a door ring; the manhole cover is rotationally arranged on the door ring, and is provided with a handle; the inner wall of the manhole flange is provided with internal teeth; the outer wall of the manhole cover is provided with external teeth; the number of the internal teeth is the same as that of the external teeth; the manhole cover is rotationally clamped in the manhole flange through the fit of the internal teeth andthe external teeth; the manhole flange is provided with a cylinder; a piston rod of the cylinder is matched with a fixed hole on the manhole cover; and a manual safety interlocking device is arrangedbetween the manhole flange and the manhole cover. The teeth structure is arranged between the manhole cover and the manhole flange, and the manhole cover can be opened by rotating by a tooth so as tohave convenient opening and closing and quick speed; and the manual safety interlocking device is matched with the cylinder to realize the safety interlocking function of the quick-opening device.

Description

(1) Technical field [0001] The invention relates to a component for an airflow dyeing machine, in particular to a quick door opening device for an airflow dyeing machine. (2) Background technology [0002] The air atomization dyeing machine adopts the principle of aerodynamics to inject the mixed air generated by the fan into the nozzle of the dyeing machine to drive the fabric to run. During the dyeing process, the airflow generated by the fan enters the nozzle and meets the dye liquor delivered by the main pump in the nozzle shell, causing the dye liquor to atomize and spray to the fabric passing through the nozzle, driving the fabric to run. Therefore, the fabric can get the best dyeing effect in the dye liquor. The equipment has the advantages of small bath ratio, low cost, less water consumption, energy saving and environmental protection, and has been widely used in the printing and dyeing industry. [0003] There is a manhole on the barrel of the airflow dyeing mach...

Problems solved by technology

The structure of this manhole cover has the following disadvantages: 1. When opening and closing the cover, four compression handwheels 4 need to be screwed one by one by hand, which is slow and inefficient; When covering, it must be ensured that there is no pressure in the cylinder, but the existing manhole cover is not equipped with a safety interlock device, which is not safe
