Technical field

The utility model relates to the production equipment field, specifically is that charge level controller is revolved in a kind of resistance.

Background technology

We can see the charge level controller of different modeling on market, and mostly its principle is to adopt ac micro motor after slowing down, and drive detection blade rotates at a slow speed.When the material level rising of tested material makes the rotation of blade be subjected to stopping, it is stopped operating with regard to the power supply that cuts off motor.As long as the material level in the storehouse is constant, this state is just kept always.When material level descends, to detect blade and lose when stopping, ortho states is replied by testing agency.The complex structure of charge level controller is revolved in resistance in the prior art, is prone to fault, and maintenance is difficult, and encapsulant is easily aging.

Summary of the invention

Shortcomings such as revolve the charge level controller complex structure in order to solve in the prior art resistance, be prone to fault, maintenance is difficult, and encapsulant is easily aging, the utility model provides a kind of blocking rotary type charge level controller, and concrete technical scheme is as follows:

Charge level controller is revolved in a kind of resistance, comprises the PCB that detects blade, main shaft, motor, reductor, spring, K switch 1 and switch place; Described motor, reductor, spring, K switch 1 and PCB are sealed in the housing; Described K switch 1 connects the break-make of control motor power; Described detection blade is connected an end of main shaft, and the other end of main shaft connects the rotor of motor by reductor.Described spring is a torsion spring, and an end of torsion spring moves with motor stator, and the other end is fixed in the housing; Also be provided with catch on the described motor stator, catch moves with motor stator; The button of described K switch 1 is on the motion path of described catch.

Described motor is located on the motor stator; End with the motor stator motion of torsion spring is located on the motor stator; Catch also is located on the motor stator; Motor stator and PCB are rotationally connected, and torsion spring is located on the rotation axis, and the other end of torsion spring is located on the PCB.

Also be provided with K switch 2 on the described PCB, the button of K switch 2 is on the motion path of described catch; Described K switch 2 connects the break-make that control has/do not have the output of material signal.Go into operation K1 and K2 is microswitch.Described K switch 1 and K2 are located at the two ends of catch motion path respectively.The button of described K switch 1 and K2 is provided with shell fragment, and an end of shell fragment is on the motion path of catch.The catch shell fragment of being open to the custom touches the button of microswitch K1, K2.

Described PCB is provided with at least 2 bayonet sockets; Bayonet socket is along the circumferential array of torsion spring, and torsion spring is connected an end and is located in the bayonet socket with PCB.Torsion spring is located in the different buckles influential to the suffered torsion of jump ring, and then catch rotates just difference of suffered torque magnitude, and the viscosity of corresponding detected material has difference.

Described detection blade has rectangle, V-arrangement, L shaped and sickleshaped, can be according to the different shapes that change blade of application requirements.

Principle of work of the present utility model: detect blade and rotate at a slow speed, after the material level rising was obstructed the rotation that detects blade, catch produced swing offset.This displacement at first makes the action of microswitch, cuts off the power supply of micromotor and it is stopped operating.The signal of material is sent in another microswitch control simultaneously.When material level decline was no longer stopped the detection blade, catch relied on spring torsion to recover ortho states.The microswitch action is connected motor power and is made its rotation, and another microswitch control is sent does not have the material signal.

The utility model is widely used in modern industry production run and storage department, and the monitoring of multiple powder in the open container or granular material and control are all had better effects.
