Abstract

The utility model relates to an automatic oil injector for a cutter wheel of a float glass transverse cutting unit, comprising a control circuit, an oil cup, an electromagnetic valve, and an oil delivery pipe. Oil injection quantity can be adjusted according to requirements by the utility model and the oil can be automatically injected on the cutter wheel to reach the purposes that the service life of the cutter wheel is increased; burrs which are produced in glass cutting is reduced; lubricating oil is saved; the cutter wheel need not be replaced frequently. The utility model is not only can be applied to different types of the glass cutting, but also can be applied to a timing oil supply apparatus of other industries.

Description

Automatic oil injector for knife-edged wheel of float glass transverse cutter

The utility model proposes a kind of float glass transverse cutting unit break bar automatic oiling device.

On floatation glass production line, finish the cut-out work of glass by transverse cutting unit.In order to prolong the work-ing life of break bar, reduce the burr of glass otch, must be to the break bar an amount of lubricating oil of annotating.Prior art is that a lubricating cup and oil filler pipe are set above break bar, to resting on the break bar oiling on the rest position.What of injection flow are by the throttling valve manual adjustment on the oil filler pipe.

The problem that prior art exists is to be not easy injection flow is controlled on the optimum level.Its result causes waste, adds shortage of oil exactly and influences the quality or the break bar life-span of otch.

Task of the present utility model is to propose a kind of float glass transverse cutting unit break bar automatic oiling device, so that injection flow is controlled at optimum regime, and the waste of minimizing lubricating oil.

The utility model utilizes the output signal of original control single chip computer on the transverse cutting unit, controls a magnetic valve that is contained between lubricating cup and the oil filler pipe, realizes the control of injection flow by regulating time that magnetic valve opens.

The float glass transverse cutting unit break bar automatic oiling device that is proposed still comprises the oil filler pipe of an oil storage cup and its below.What distinguish is: installed the fuel-flow control loop of a magnetic valve and this magnetic valve additional between said oil storage cup and oil filler pipe, made this magnetic valve be controlled by the micro-chip of control transverse cutting unit break bar action, refueled for it before the break bar motion.

On existing transverse cutting unit, all comprise a reflex glass length and control the micro-chip that break bar moves that this micro-chip is being controlled the current supply circuit of transverse cutting unit drive-motor by a rly..Drive coil and fuel-flow control loop that the utility model utilizes the remaining a pair of normal opened contact ZJU of this rly. to switch said magnetic valve.When transverse cutting unit begins the action cutting, this junction closure, magnetic valve is connected oil circuit, and break bar is refueled.

Said fuel-flow control loop is actually a rly. self-sustaining time delay circuit.Its effect is to make magnetic valve keep one adjustable period of adhesive, to guarantee suitable injection flow.The utility model utilizes time relay self-hold circuit to realize it.

The utility model comprises 2 width of cloth accompanying drawings.Wherein

Fig. 1 is the electrical schematic diagram of the utility model automatic oiling device;

Fig. 2 is the formation synoptic diagram of this device.

Below will contrast the label of accompanying drawing and the knot formation of the present utility model that is situated between in detail in conjunction with the embodiments.

With reference to claims and contrast accompanying drawing, the professional is easy to implement the utility model.

As shown in Figure 2, automatic oiling device of the present utility model comprises the oil filler pipe (5) of an oil storage cup (1) (so that holding more lubricating oil) that has strengthened and its below.Between replaces the break-make of the throttle valve control oil circuit of original manual adjustment with a magnetic valve (4).The drive coil of magnetic valve is connected in the fuel-flow control loop.

In Fig. 1, said fuel-flow control loop mainly comprises a time relay sj and a guard relay ZJ.The A of circuit, N end connects both ends of power respectively; The a pair of normally closed contact SJ-1 of a pair of normal opened contact ZJU of micro-chip output relay and the SJ of the time relay is connected in two rly.s and the magnetic valve common current supply circuit; The a pair of normal opened contact ZJ-2 of guard relay only is connected in the current supply circuit of magnetic valve, another to normal opened contact ZJ-1 with ZJU be connected into " with " logic.

The principle of foregoing circuit is: when the micro-chip control transverse cutting unit begins to move, and contact ZJU closure, power supply is added on time relay sj and the guard relay ZJ through ZJU, SJ-1, makes contact ZJ-2 closed thereupon, and magnetic valve DCF gets electric connection oiling oil circuit.After one section time-delay, the normally closed contact SJ-1 disjunction of the time relay makes two docking point ZJ-1 of guard relay and ZJ-2 disjunction simultaneously, has cut off the current supply circuit of magnetic valve, and oiling finishes.Simultaneously, since the output relay contact ZJU of micro-chip closed very short time, this moment of disjunction.So, along with the disconnection of ZJ-1, time relay sj and guard relay ZJ no longer adhesive approximately.Circuit is in the state that wait triggers next time.

How much can regulating by the delay time of the time relay easily of injection flow.

Automatic oiling device of the present utility model can be finished timing, the quantitatively oiling to the transverse cutting unit break bar automatically, changed the continuous state of former oiling device permanent current, can obviously reduce the waste of lubricating oil, and can more effectively guarantee cutting quality, improve the break bar life-span.
