Abstract
The utility model discloses a self -adaptation foam burnishing machine, including the frame, ann has driving pulley and from the driven pulleys in the frame, and driving pulley links to each other with the initiative motor, and ann has the abrasive band on driving pulley and from the driven pulleys, and the frame below is equipped with the conveyer belt, the motion of conveyor belt motor drive conveyer belt, and its characterized in that, the initiative motor links to each other with the converter through converting circuit, and the converter links to each other with conveyor belt motor. The device can effectively protect the motor according to the thickness degree adjustment input speed of foam self, still can improve the efficiency of polishing in good time.
Description
Technical field
The utility model relates to a kind of device, is specifically related to a kind of self adaptation foam polishing machine that can automatically regulate according to abrasive band live load conveyer belt charging rate.
Background technology
Foam polishing machine is the equipment for polishing foam surface, in frame, be equipped with along the vertical direction the abrasive band of running capable of circulation, below, abrasive band is horizontal conveying belt, and foam crude product is placed on horizontal conveying belt and travels forward, and contact with lower end, abrasive band, motion limit, limit is polished. This polishing machine in actual use, can only set definite line speed, can not adjust charging rate according to foam crude product surface roughness, in the time that abrasive band runs into thicker difficult polishing position, conveyer belt can not slow down, abrasive band motor is likely by overload burning, and in the time that abrasive band runs into the position of thinner easy polishing, conveyer belt also can hoisting velocity not raised the efficiency.
Utility model content
The purpose of this utility model is to provide a kind of self adaptation foam polishing machine, and this device can be adjusted charging rate according to the thickness degree of foam self, can effectively protect motor, also can improve grinding efficiency in good time.
For achieving the above object, the utility model is taked following technical scheme:
A kind of self adaptation foam polishing machine, comprise frame, in frame, be equipped with driving pulley and driven pulley, driving pulley is connected with active motor, on driving pulley and driven pulley, be equipped with abrasive band, frame below is provided with conveyer belt, and conveyer belt motor drives conveyer belt, master tape motor is connected with frequency converter through change-over circuit, and frequency converter is connected with conveyer belt motor.
Further, described change-over circuit is connected with the current transformer in active motor, obtains after current signal also amplifies and inputs to frequency converter, and the UVW mouth of frequency converter is connected with driving-belt motor.
In said apparatus, change-over circuit is connected with master tape motor transformer, transformer is used for exporting low-tension current, after this electric current input change-over circuit, through change-over circuit, current signal is zoomed into voltage signal and input to again frequency converter, frequency converter can produce the alternating current of 15~55Hz for conveyer belt motor, such benefit is under the effect that does not reduce conveyer belt motor output torque, to adjust the gait of march of conveyer belt, in the time that abrasive band runs into compared with thickness portion, master tape current of electric increases, it is slack-off that now frequency converter makes conveyer belt motor speed, feeding speed declines, can avoid is that belt sanding difficulty is too high, prevent that master tape over current of motor from burning, when abrasive band runs into thinner part, master tape motor load alleviates electric current and reduces, now feeding is accordingly accelerated, when after the complete sheet material of sanding, main empty load of motor feeding speed can reach 55Hz and enhance productivity.
Brief description of the drawings
Fig. 1 is the utility model abrasive band and conveyer structure schematic diagram;
Fig. 2 is the utility model interlock circuit block diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As Fig. 1 shows the utility model abrasive band and conveyer structure schematic diagram, abrasive band 3 is arranged on driving pulley 1 and driven pulley 2, driving pulley 1 and driven pulley 2 are vertically arranged in frame (not shown), and driving pulley is connected with the output shaft of active motor. Below abrasive band 3, be equipped with conveyer belt 4, conveyer belt motor drives conveyer belt 4 to move by belt wheel 5 and belt wheel 6. Initiatively motor internal is equipped with current transformer, and the output of current transformer is connected with change-over circuit plate, and change-over circuit plate is provided with change-over circuit, and change-over circuit obtains electric current and current signal is amplified, and then inputs to the frequency converter being connected with change-over circuit. The power supply of frequency converter is 380V alternating current, the frequency shift of 50Hz can be become change within the scope of 15~55Hz, and the UVW mouth of frequency converter connects conveyer belt motor, drives conveyer belt motor to carry out work (Fig. 2).
In work, be placed with cystosepiment crude product on conveyer belt 4, uneven distribution is even, advancing to abrasive band is polished for 3 times, in the time that thicker position is polished, material feeding amount in abrasive band increases, the difficulty of advancing, master tape current of electric increases, this situation is converted electric circuit inspection and signal is exported to frequency converter, and frequency converter is controlled conveyer belt motor and slowed down rotating speed, and charging rate is slowed down, make that master tape motor load is constant works in the situation that being full nonoverload again for one, now can avoid burning initiatively motor; In the time that thinner position is polished, initiatively current of electric diminishes, and corresponding Frequency Converter Control conveyer belt increases gait of march, to improve grinding efficiency.
The present embodiment is an explanation to the utility model design and realization just, is not limited, and under the utility model design, the technical scheme converting without essence is still in protection domain.
