The specific embodiment
Below in conjunction with the drawings the specific embodiment is carried out comparatively detailed explanation to the characteristics of the multi-line cutting machine of the utility model; But be not limited only to these embodiments; Do not breaking away under the prerequisite that the utility model conceives basically; More changeableization or improved other embodiments can also be arranged, and these variations and improvement all should belong to the scope of the utility model.
Shown in Figure 1 is the structural representation of cutting chamber in the existing multi-line cutting machine.
This multi-line cutting machine comprises: the casing (not shown), be arranged on the cutting chamber in the casing, the top of cutting chamber is provided with work stage 1; The below of work stage 1 is provided with guide roller 3, and guide roller 3 is divided into the main traverse line wheel and from guide roller, line of cut is from the inboard inlet wire of main traverse line wheel; Around the outside outlet of behind guide roller, taking turns from main traverse line; Form netted cut surface 5, workpiece 2 to be cut is bonded to work plate 4 through glue-line and glass plate, and work plate 4 is connected to work stage 1; Workpiece 2 can move up and down perpendicular to netted cut surface with work stage 1; Thereby workpiece is cut in flakes, below netted cut surface 5, two guide roller inboards, near each guide roller 3 and be parallel to guide roller guide roller baffle plate 8 is set respectively, the two ends of guide roller baffle plate 8 are fixed on the casing inner wall.
The multi-line cutting machine that has line bow detector of the utility model is the improvement of on above-mentioned existing multi-line cutting machine basis, carrying out.On two guide roller baffle plates 8, be symmetrical set line bow detector 9, be used for surveying the line bow height that cutting process forms.
Shown in Figure 2 is structural representation according to a kind of embodiment of the utility model.
According to a kind of optimal way, one route bow detector 9 sends cue when the line bow highly surpasses first setting value; When the line bow highly surpassed second setting value, another route bow detector 9 sent stop signal, makes multi-line cutting machine stop the feeding of workpiece.
Particularly, for example, silicon rod or silico briquette are under normal cut state, and line bow basic controlling is in the 3-7mm scope.If when having hard impurity such as hard point or piece or mortar cutting power obviously not enough in the silico briquette, the line bow can be slowly increase tendency, thereby the hidden danger that causes breaking sharply increases.Therefore, preferably, said first setting value is 7mm, and second setting value is 12mm.Said setting value also can suitably be adjusted according to concrete needs or concrete equipment.
According to a kind of optimal way of the utility model, said line bow detector comprises the base with guide roller baffle plate coupling, the connector that base is connected with the guide roller baffle plate, and be parallel to guide roller and baffle plate on the base and with the proximity transducer of spaced set.For example, said proximity transducer is a capacitive proximity sensor.For the used sensor of the line of the utility model bow detector, not special the qualification is as long as the sensor that can detection range changes is all applicable.
According to a kind of optimal way of the utility model, two guide roller baffle plates form funnel shaped, with the shape near guide roller.
According to a kind of optimal way of the utility model, said cue is indicator lamp or alarm sound.Also not special qualification to this is as long as it is all available to send the signal of prompting or warning.
According to a kind of optimal way of the utility model, line bow detector preferably adopts the operation principle of capacitive proximity sensor to be: can form a capacitor between the detection faces of sensor and the earth, participate in oscillation circuit work, the initial oscillatory regime that is in.When line bow proximity transducer detection faces, the capacitance in loop changes, and makes the high-frequency generator vibration.Vibration converts the signal of telecommunication into this two states of failure of oscillation and changes into binary switching signal through amplifier.
A concrete example is: when the line bow surpassed 7mm, after the monitoring of No. one survey meter, PLC exported signal alarm, the caution operator.When the line bow surpassed 12mm, another road survey meter captured, and the output signal feedback is to workpiece feeding motor.The output loop of motor realizes that through A.C. contactor, the time relay work of motor stops.Reach the minimizing of line bow through the high-speed motion of gauze this moment.When treating that the line bow returns to home (in the 7mm), motor is started working, and workbench continues feeding.Do not reduce trend or increase if the abnormal wire bow is, the operator must pay close attention to, and shutdown inspection is handled in case of necessity.
