When automatic lubrication mechanism for conveyor chain provided by the invention is installed, under the preferable case, should guarantee that the detecting head of sensor 2 and the installation site of spraying nipple 24 differ an integer complete chain pitch number, and should guarantee the leak tightness of each joint of cylinder body and entire mechanism.
Below with reference to Fig. 1, be described utilizing automatic lubrication mechanism for conveyor chain provided by the invention to carry out the lubricated process of conveyer chain.
When sensor 2 sensed roller 19 by the time, electromagnetic valve 3 is charged to begin action, and source of the gas 21 is communicated with gas circuit 4, ventilates to the right chamber of gas-liquid combination cylinder 1 to pass through gas circuit 4.Under the effect of air pressure, the piston 7 in the gas-liquid combination cylinder 1 is to left movement, and the air pressure in the gas-liquid combination cylinder 1 left chamber increases, and this moment, the check valve 23 at oil outlet 11 places was got through by unidirectional, so that a part of gas in the gas-liquid combination cylinder 1 left chamber is discharged by pipeline 12.After roller 19 passed through, sensor 2 inductions were less than roller, and then electromagnetic valve 3 resets, and this moment, gas circuit 4 was not communicated with source of the gas 21, and was communicated with atmosphere.Because the right chamber of gas-liquid combination cylinder 1 communicates with atmosphere by gas circuit 4, therefore the gaseous tension in the right chamber reduces, and is returned to initial position under the effect of the piston 7 return spare 8 in cylinder in the gas-liquid combination cylinder 1 simultaneously.Gas volume increase in this moment gas-liquid combination cylinder 1 left chamber and pressure reduces, therefore the air pressure in the chamber, a cylinder body left side will and external pressure between form draught head, cause the check valve 23 at oil outlet 11 places to be closed, and the check valve 23 at fuel feed hole 10 places is opened by unidirectional, thereby the fluid in the feed apparatus 22 will be fed in the left chamber of gas-liquid combination cylinder 1 by pipeline 25.Air pressure in the fluid amount that enters gas-liquid combination cylinder 1 left chamber makes left chamber goes back up to barometric pressure when almost equal, and the check valve 23 at oil inlet 10 places is closed.So far, the action first time after whole automatic lubrication mechanism has just installed, promptly the exhaust oil-absorbing process is finished.
Be the process of automatic lubrication mechanism oil spout below: when sensor 2 sensed again roller 19 by the time, electromagnetic valve 3 begins action with charged, and source of the gas 21 is communicated with gas circuit 4, ventilates to the right chamber of gas-liquid combination cylinder 1 to pass through gas circuit 4.Under the effect of air pressure, piston 7 beginnings in the gas-liquid combination cylinder 1 are to left movement, air pressure in the gas-liquid combination cylinder 1 left chamber increases, and this moment, the check valve 23 at oil outlet 11 places was got through by unidirectional, so that the fluid in the gas-liquid combination cylinder 1 left chamber is discharged to spraying nipple 24 places by pipeline 12.Because the detecting head of sensor 2 and the installation site of spraying nipple 24 just in time differ an integer complete chain pitch number, therefore below spraying nipple 24, also just in time there is roller 19 to pass through this moment, thereby fluid can be ejected on the roller, to be lubricated.After roller 19 passed through, sensor 2 inductions were less than roller, and then electromagnetic valve 3 resets, and this moment, gas circuit 4 was not communicated with source of the gas 21, and was communicated with atmosphere.Because the right chamber of gas-liquid combination cylinder 1 communicates with atmosphere by gas circuit 4, therefore the gaseous tension in the right chamber reduces, and is returned to initial position under the effect of the piston 7 return spare 8 in cylinder in the gas-liquid combination cylinder 1 simultaneously.Owing to part fluid be discharged from make pressure reduce in the gas-liquid combination cylinder 1 left chamber this moment, therefore form draught head between the air pressure in chamber, a cylinder body left side and the external pressure, cause the check valve 23 at oil outlet 11 places to be closed, and the check valve 23 at oil-feed 10 places is opened by unidirectional under atmospheric effect, thereby the fluid in the feed apparatus 22 will be fed in the left chamber of gas-liquid combination cylinder 1 by pipeline 25.Fluid amount in entering gas-liquid combination cylinder 1 left chamber makes the air pressure in the chamber, a cylinder body left side go back up to barometric pressure when almost equal, and the check valve 23 at oil inlet 10 places will be closed.So far, whole automatic lubrication mechanism is finished an oil extraction oil-absorbing process.When sensor 2 sensed again roller 19 by the time, automatic lubrication mechanism will repeat above the action.
Need to prove that at last the driving gas circuit of described gas circuit 4 in the automatic lubrication mechanism of the present invention and 9 formed driven plunger 7 motions of the air extractor vent of gas-liquid combination cylinder 1 also can directly be replaced with cylinder.In this case, only the piston rod end of cylinder need be connected with piston 7, with the turnover gas interface on the electromagnetic valve 3 respectively with the corresponding connection of turnover tracheae of cylinder, get final product the motion of driven plunger 7.
