Abstract
The utility model relates to an overload protection device for a stone cutting machine, which is characterized by comprising a photoelectric proximity switch at the side part of a rotary cutting blade of the stone cutting machine, wherein the signal output end of the photoelectric proximity switch is connected with the signal input end of a counter; and the control output end of the counter is connected in series with a motor contactor and a motor power supply. According to the utility model, the photoelectric proximity switch at the side part of the rotary cutting blade of the stone cutting machine can sense the rotational speed of the rotary cutting blade, when the rotation speed is smaller than a certain speed, the counter is disconnected with the motor contactor and the motor power supply so as to stop the motor, and as a result, the situation that the motor, the contactor or a belt and other part is damaged when the cutting blade in high load is still in low-speed rotation.
Description
Technical field:
The utility model relates to a kind of stonecutter overload protection arrangement.
Background technology:
Stonecutter is widely used in the cutting processing of stone material, and stonecutter mainly includes motor, motor-operated pulley mechanism and belt wheel and drives the cutting blade that rotates, and cutting blade is when cutting normal consistency building stones; The linear velocity of cutting blade, belt pulley, motor is the same; But when cutting blade cut to the king-sized stone material of hardness, cutting blade receives resistance to be increased greatly, and rotating speed is very low; The motor of this moment is still worked; Just still can drive belt and rotate, belt will skid on the belt wheel of cutting blade side, causes the violent friction of belt to burn easily; If belt and belt pulley installation this moment is tighter, motor, even the motor contactor will burn, and brings about great losses.
Summary of the invention:
The purpose of the utility model is to provide a kind of stonecutter overload protection arrangement, and this stonecutter overload protection arrangement is not only simple in structure, reasonable in design, and helps preventing cutting blade from running into high load capacity and burn parts such as motor when slowly running.
The utility model stonecutter overload protection arrangement; It is characterized in that: comprise that the photoelectricity that is arranged on stonecutter rotary cutter sheet sidepiece is near switch; Said photoelectricity is connected with a counter signals input near the signal output part of switch, and said counter controls output is connected in series with motor contactor and motor power.
Above-mentioned counter is the ZN48 counter.
Above-mentioned counter the 3rd pin is connected with an end of motor power behind a normally closed switch, and said counter the 4th pin is connected with a control end of electric machine controller, and another control end of electric machine controller is connected with the other end of motor power.
Above-mentioned photoelectricity is connected with the 8th pin of counter near the signal output part of switch.
Above-mentioned counter the 1st, 2 pins are connected with the 220V alternating current.
Above-mentioned photoelectricity is connected with counter the 6th, 9 pins respectively near two feeder ears of switch.
Above-mentioned counter the 3rd pin and the 5th pin are normally offs.
Above-mentioned counter the 3rd pin and the 4th pin are normally opens.
The operation principle of the utility model: the photoelectricity that is installed in stonecutter rotary cutter sheet sidepiece can be sensed the rotating speed of rotary cutter sheet near switch; When its rotating speed during less than certain rotating speed (this rotating speed can be regulated as required); Counter promptly cuts off being connected of motor contactor and motor power; Let motor outage, thereby motor is just quit work, avoided cutting blade to run into high load capacity and burn parts such as motor, contactor or belt when slowly running.
Description of drawings:
Fig. 1 is the organigram of stonecutter;
Fig. 2 is the circuit theory diagrams of the utility model;
Wherein 7 is stone material, and 8 is motor.
Embodiment:
The utility model stonecutter overload protection arrangement; Comprise that the photoelectricity that is arranged on stonecutter rotary cutter sheet 1 sidepiece is near switch 2; Said photoelectricity is connected with a counter 4 signal input parts 5 near the signal output part 3 of switch, and said counter 4 control output ends are connected in series with motor contactor 6 and motor power.Photoelectricity is provided with the position and can makes as required near switch 2, as long as can detect the rotating speed of rotary cutter sheet.
For reasonable in design, above-mentioned counter is the ZN48 counter.
Above-mentioned counter the 3rd pin is connected with an end of motor power behind a normally closed switch, and said counter the 4th pin is connected with a control end of electric machine controller, and another control end of electric machine controller is connected with the other end of motor power.
Above-mentioned photoelectricity is connected with the 8th pin of counter near the signal output part of switch.
Above-mentioned counter the 1st, 2 pins are connected with the 220V alternating current.
Above-mentioned photoelectricity is connected with counter the 6th, 9 pins respectively near two feeder ears of switch.
Above-mentioned counter the 3rd pin and the 5th pin are normally offs.
Above-mentioned counter the 3rd pin and the 4th pin are normally opens.
The operation principle of the utility model: the photoelectricity that is installed in stonecutter rotary cutter sheet sidepiece can be sensed the rotating speed of rotary cutter sheet near switch; When its rotating speed during less than certain rotating speed (this rotating speed can be regulated as required); Counter promptly cuts off being connected of motor contactor and motor power; Thereby motor is just quit work, avoided cutting blade to run into high load capacity and burn parts such as motor, contactor or belt when slowly running.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
