Dealing with common faults of color sorter

Release date:2020-02-17 00:00 Sources: click:

Repeat the test for dust valve in the air leakage valve of the solenoid valve, and replace the solenoid valve if the solenoid valve is damaged. Plug and socket of the solenoid valve that does not operate the valve are not in good contact, and then plug and unplug again, and repair the position of the poor contact. When the valve core is disconnected, replace the solenoid valve. If the color selection plate is damaged, replace the color selection plate. There is dust in the solenoid valve with small air injection volume. Repeat the high frequency test for the solenoid valve. Check the pressure gauge and related air circuit if the air pressure is too low.


The single side sorting effect of the whole machine is poor, the rod less cylinder is not in place, the dust cleaning effect is poor, the dust scraper is adjusted, and the dust scraping speed of the color separator is often stopped, the flexibility is too high, the flexibility is readjusted, the background board is not adjusted properly, the raw material of the background board is too high and the output is reduced. According to the difference of optical properties of materials, the photoelectric technology is used to automatically sort out the heterochromatic particles.


The photoelectric sorter is suitable for the selection of granular plastics. In the process of belt conveying, a series of CCD cameras are used to scan the defective products instantaneously, and then the compressed air ejected from the high-speed nozzle is used to remove the defective products, especially the two-stage secondary separation is used to obtain the high-purity and high-quality finished products.


Working principle of accessories of coarse grain color sorter: the selected materials enter the machine from the rice hopper at the top, fall down along the feeding distribution trough through the vibration of the feeding device (vibrator), accelerate the sliding down the meter channel and enter the observation port in the sorting room through the upper end of the meter channel, and pass between the image processing sensor CCD and the background device. Under the function of LED light source, the CCD receives the information from Synthetic optical signal of the selected material.


The output signal is generated by the system, amplified and transmitted to the DSP operation and processing system, and then the control system sends out the command to drive the injection solenoid valve to act, and the heterochromatic particles are blown to the waste cavity of the discharge hopper to flow away. And the good selected materials continue to fall into the finished product cavity of the receiving hopper and flow out, so that the selected materials can achieve the purpose of selection.
