Glycerol adding system for filter stick forming machines

Abstract

The invention provides a glycerol adding system for filter stick forming machines. Glycerol is added into a plurality of glycerol storage tanks of the filter stick forming machines from a total glycerol tank; each glycerol storage tank is communicated with the total glycerol tank through a conveying branch pipe; a corrosion-resistant globe valve is arranged on each conveying branch pipe; a corrosion-resistant electromagnetic valve is further arranged on each conveying branch pipe; a glycerol floater switch is arranged in each glycerol storage tank; four liquid level sensors are respectively arranged at four positions of different heights on the inner wall of each glycerol storage tank; signal output ends of the liquid level sensors are connected with a signal input end of a PLC (Programmable Logic Controller); and a signal output end of the PLC is connected with the corrosion-resistant electromagnetic valves and a sound and light alarm device. According to the glycerol adding system, the glycerol adding is automatically controlled by using the PLC, and the sound and light alarm device is provided, so that the glycerol adding system for the filter stick forming machines is good in safety.

Description

technical field [0001] The invention relates to a system for adding glycerin to a filter stick forming machine. Background technique [0002] In the filter rod production workshop of a cigarette factory, the plasticizer used in the production of filter rods is glycerol acetate, which is a colorless, dense, and highly corrosive chemical agent. The glycerin injection method is to inject from the total glycerin tank to several glycerin storage tanks of the filter rod forming machine. The distance between the total glycerin tank and the glycerin storage tank is about 10 meters. The corrosion-resistant ball valve manually adds glycerin by manually controlling the corrosion-resistant ball valve. This method adopts a 10m self-flowing injection method. When injecting, the pressure is large and the flow rate is large. The indicator light of glycerin filling is not obvious. Position display, inconvenient to observe, manual control of corrosion-resistant ball valves is not safe, repla...

When injecting, the pressure is large and the flow rate is large. The indicator light of glycerin filling is not obvious. Position display, inconvenient to observe, manual control of corrosion-resistant ball valves is not safe, replacement and maintenance of corrosion-resistant ball valves is inconvenient, resulting in glycerin often overflowing the ground, bringing huge safety hazards to the production site, personnel and materials
