Description
Technical field
What the present invention relates to is a kind of shredder test shovel loader, says more specifically the electronic load simulating device of a kind of shredder.
Background technology
Shredder is office equipment commonly used in a kind of office, and the paper part data that it can no longer need the user is destroyed.Along with electronic technology constantly develops, the function of shredder is little by little abundant and powerful, and the consumer also progressively promotes the requirement of shredder, and the thing followed is the increasing with the test dynamics to its exploitation of shredder manufacturer.
Each shredder manufacturer must comprise the test of shredder long term wear in shredder dispatches from the factory test at present.Long term wear test refers to that test machine is operated under high strength cut paper state, continues the degree of wear that cut paper a period of time tests the original papers such as motor in paper shredder core, reduction gearing, slitter shaft, movement support plate.
The shredder long term wear of current each manufacturer is tested equal Application standard paper and is tested, and has wasted a large amount of paper in the process of test, has run counter to the environmental protection aim of low-carbon energy-saving.
Summary of the invention
The object of the present invention is to provide a kind of paper that can substitute shredder to be carried out to the electronic load simulating device of shredder of long term wear test.
The object of the present invention is achieved like this: the output shaft of shredder 1 is connected with an input end of torque sensor 3, another input end of torque sensor 3 is connected with the output shaft of permagnetic synchronous motor 6 by speed reduction unit 5, torque sensor 3 is by data collecting card 8 and data handling machine 9 electrical connections, and data handling machine 9 is controlled permagnetic synchronous motor 6 by the driver 7 of permagnetic synchronous motor; At the work initial stage, with permagnetic synchronous motor, drive shredder to rotate, to shredder, put into tested paper, torque data during shredded paper detects by torque sensor and is transferred to data handling machine by data collecting card, shows torque curve and preserves; During normal operation, data handling machine is using the torque curve that collects as the given signal of torque, measure in real time dtc signal simultaneously, the dtc signal of measuring is in real time compared with given signal, using difference torque set-point as the driver of permagnetic synchronous motor after the PID regulator is regulated, control the torque curve recorded when permagnetic synchronous motor makes the torque curve of output and cut paper and approach.
The present invention can also comprise:
1, between an input end of the output shaft of shredder 1 and torque sensor 3, by the first shaft coupling 2, be connected.
2, between torque sensor 3 and speed reduction unit 5, by the second shaft coupling 4, be connected.
3, data handling machine 9 is provided with the user images display interface.
The electronic load simulating device of shredder of the present invention can also comprise such Some features: the four-quadrant operation characteristic of permagnetic synchronous motor 6 can be by electric energy feedback to electrical network.2, the driving signal of permagnetic synchronous motor is that the torque curve collected by data collecting card 8 obtains after automatic control algorithm is processed.3, permagnetic synchronous motor driver 7 Negotiation speed closed-loop control permagnetic synchronous motors 6.4, the control strategy of electronic load simulating device is the torque closed-loop control.
The beneficial effect that the present invention reaches is: can replace paper shredder is carried out to the long term wear test, realize the with no paper wear and aging test of the original papers such as the motor except blade in paper shredder core, reduction gearing, slitter shaft, movement support plate, load torque is carried out to Real-Time Monitoring, simultaneously the four-quadrant operation characteristic of permagnetic synchronous motor can, by the electric energy feedback that produces in process of the test to electrical network, reach the purpose of energy-conserving and environment-protective.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further for example:
In conjunction with Fig. 1, the electronic load simulating device of shredder comprises the speed reduction unit 5 of shaft coupling 2, torque sensor 3, shaft coupling 4, load simulating device, the power source of permagnetic synchronous motor 6(load simulating device), permagnetic synchronous motor driver 7, data collecting card 8, data handling machine 9.The output shaft of shredder 1 is by one of them input end mechanical connection of shaft coupling 2 and torque sensor 3, and another input end of torque sensor 3 and speed reduction unit 5 are by shaft coupling 4 mechanical connections; The output terminal mechanical connection of the other end of speed reduction unit 5 and permagnetic synchronous motor 6; The input end of permagnetic synchronous motor 6 is by driver 7 and data handling machine 9 electrical connections of permagnetic synchronous motor.Torque sensor 3 is by data collecting card 8 and data handling machine 9 electrical connections.
The course of work of the present invention is as follows:
