An automatic dust removal structure for a cigarette machine

technical field

The invention relates to an automatic dust removal structure for cigarette machines, belonging to the technical field of dust removal for cigarette machines.

Background technique

In a cigarette factory, one fan can provide the wind pressure required for several cigarette machines to smoke tobacco wire, forming a set of wind wire feeding system. When the feeding rod machine of the cigarette machine stops smoking filaments at the same time or most of the time, the air door of the filament suction duct is closed, and the pressure of the filament suction duct and the fan casing increases, which is easy to damage the equipment. Therefore, a supplementary air duct and a pressure monitor are usually set on the suction duct of the fan, and a damper is installed on the supplementary air duct. The solenoid valve controls the opening of the air door of the air supply duct to ensure the relative stability of the wind force for smoking the filament; however, the air force from the air supply opening of the air duct is not effectively utilized, and the energy consumption is high. For this reason, publication number is the Chinese patent document of CN1421165A, discloses a kind of cigarette machine wind power wire feeding economical air supplement method, such as there are N cigarette machines in the cigarette machine wind wire feeding device, and its economic air volume K is equal to or greater than N/2 and an integer less than N, the design parameters of the device and the selection of equipment are determined based on the design conditions of K units simultaneously sucking silk or making up air. The total economic air volume of the device is the sum of the air volumes of the K units of cigarette machines, and the field bus technology is used. , control the suction valve and air supply valve of all cigarette machines to act according to the sequence, so that the device works in the economical air supply state with K sets of silk suction valve or air supply valve opened, that is, at any time, only K cigarette machines are among them. In the state of sucking silk or supplying air, the remaining N--K cigarette machines are in the state of neither sucking silk nor supplying air. The air volume of the device of the invention is 1/2 to 2/3 of the existing technology, and the selection specifications of fans, dust collectors and mufflers are small, which saves investment and reduces energy consumption; the existing device can be appropriately expanded, with flexible investment. long-term stability; intelligent control improves the lowering ability and control level of the device, and can be extended to data collection and centralized monitoring of wind wire feeding; because the device of the present invention controls the wire suction valve and the air supply valve separately, it can be Through various control advances, the influence of switching is eliminated as much as possible, so that the suction wind speed is more stable.
