Improvement of smoke conveyor belt oil lubrication

The smoke conveyor belt 2019 - oil lubrication way of improvement 08 - Xu help abstract: to fuling smoke cigarette factories of the conveyer belt in the process of long-term operation, the conveyor belt and brace friction make the conveyor belt easily stretched and even be pulled apart or cause drag mark. In order to reduce the friction between the conveyor belt and racks, prolong service life, with the method of artificial brush oil lubrication. But, artificial labor intensity big brush oil, the work high above the poor safety, uneven brush oil, lubrication effect is poor. Aiming at this phenomenon, to improve the lubrication of smoke conveyor belt, using the single chip microcomputer control, automatic oil lubrication. Oil evenly, good lubrication effect, reduce the resistance of the traction motor, prolong the service life of the conveyor belt, reduces the labor intensity and avoid the risk of aerial work. Key words: the smoke conveyor belt; Artificial brush oil; Oil coating equipment; Automatic fuling smoke cigarette factories of the transmission line is shandong hongfa tobacco group Qingdao machinery co. , LTD. , which smoke conveyor line each conveying capacity of 70 m/min. On the conveyor belt from the design, there is no automatic oil lubrication device design, require the use of artificial brush oil lubrication on a regular basis. Run after six years of observation, conveyor belt weight is very big, plus the weight of the smoke, the friction between conveyor belt and brace is very large. We found that the artificial oil brush brush oil lubrication are uneven, poor lubrication effect, 5 - every year The phenomenon of eight conveyor belt is pulled; Due to the particularity of the production site, the conveyor belt is mounted in the air is relatively high, each time you brush oil maintenance personnel standing on high in one hand and a brush, on the other hand the oil box, on the conveyor belt on both sides, the risk is big. Aimed at the problem no literature reports. For this purpose, the article in the smoke on the conveyor belt to install automatic oil lubrication device, prolongs the service life of conveyor belt, improve production efficiency, reduce labor intensity and avoid the risk of aerial work. 1 after the repeated observation and analysis of existing problems, the cause of conveyor belt is stretched or snap is (1) the work high above the artificial brush oil, operation inconvenient, conveyor with brush oil leakage phenomenon, lubrication blind area; (2) artificial uneven brush oil, lubrication effect is poor, lead to the friction between the conveyor belt and brace is too large. Improved method (2 1) Design on the conveyor chain board install automatic oil lubrication device. The device consists of a solenoid valve, oil mist, regulating valve, nozzle, controller ( As shown in figure 1) 。 Structure principle: solenoid valve 5 air inlet to the outlet pressure regulating valve 4, pressure regulating valve of the inlet air 3, 4 solenoid valve 5 of the outlet connect the inlet of oil mist detector 1 10. Regulating valve 2 inlet air 3, pressure regulating valve of the outlet oil mist 1 2 of 12 the intake. Oil mist detector 1 on the oil outlet 11 island 7 inlet connection valve, valve island 7 with multiple electromagnetic valve of 8, and the oil inlet of every solenoid valve 8 and 7 of the inlet valve island are interlinked, each electromagnetic valve of 8 oil outlet corresponds to a nozzle n inlet connection. Controller on the 6 equipped with multiple outputs, one of the output termination, electromagnetic valve, the control end of the 5 for the rest of the output terminal connected to a solenoid valve 8 control. （ 2) Design control part of the automatic oil lubrication device. Control principle is shown in figure 2: give the controller with 220 vac, the transformer into a 14 vac and rectification to dc supply decoupling (motherboard MCU and light MOC3021) , the motherboard MCU, start the program combining the user's timing set, oil mist device control circuit output to a low level, 1 to n road one all the way to the output of a low level, oil mist device control circuit output to meet the control end of the solenoid valve 5, 1 to n corresponding connection n road, electromagnetic valve, the control end of the 8 to get the way light coupling low level ( MOC3021) Conduction, followed by light coupling with the corresponding thyristor ( S0806） Conduction, the thyristor ( S0806） Corresponding to the electromagnetic valve of 8 conductance tong. For example: 1, the low level after K end, U1 and Uk conduction, Q1 and Qk conduction, the motherboard of 1 side and K and electricity, and K end connection of the electromagnetic valve 5 conduction 1 gas supply to the oil mist detector, at the same time 8 conduction solenoid valve, which is connected with one end to the corresponding nozzle n oil supply, shower n injection to the both sides of the conveyor belt position complete oil lubrication of conveyor belt. （ 3) Running test. Controller when the pressure adjustment appropriate values, set specific job date and time. Work time trigger solenoid valve 5, at the same time let n way solenoid valve of 8 a way through. Electromagnetic valve 5 to applying compressed air, oil mist device 1 oil mist detector controlled by electromagnetic valve 8 1 output of oil and gas mixture, then to shower n atomization, after atomization of lubrication oil mist spraying to travel to achieve. Article 3 improvement effect on the smoke conveyor belt after installing automatic oil lubrication device, workshop cancelled artificial brush oil lubrication, reduce labor intensity and avoid the risk of aerial work. After atomizing oil mist evenly into the transmission, without blind area, the lubrication effect is good, since improved operation one year, did not appear the phenomenon of conveyor belt is pulled, reduces maintenance time, improve the production efficiency.
