This washing process is very effective for handwoven carpets. When the carpet enters the machine, the washing process continues, and the first problem is the existence of carpets with different dimensions and thicknesses, which requires the detection of the height (thickness) of the carpet for complete and accurate washing, which is done by an encoder. Considering the increase in the thickness of the carpet by the mechanical system that is designed, the encoder gives a larger numerical value to the intelligent control system (PLC) according to which the height of the washing brushes is adjusted.
At the same time as This work, and with the carpet in front, the water and shampoo valves are turned on to start the washing process. The reason for this is the accurate positioning of the carpet and then allowing the solution and water to enter the carpet and inside the machine. After adding water and shampoo, it is time to wash using frequency brushes
Carpet Washing Stage or Frequency Brush
Frequency device in model 18 and 36 brushes are oscillating on the carpet with a frequency of 30-40. After this process, it is time for the first stage of carpet rinsing, in this stage, according to the position of the carpet, which is detected by the sensor installed on the shaft of the grip bar, and then the water solenoid valve is connected. The detergent will be from the carpet. After this stage, the carpet is put into the enlarged roller brushes, scale and lint removal is done. carpet) and push the carpet forward.
However, when a major part of the carpet passes, it cannot be returned, and the carpet reaches the next stage, i.e. final drainage, without being thrown or damaged. The carpet detector can be detected, the built-in car wash (water jet) starts spraying water and this process continues until the end of the carpet. The sensors and tools used to control this advanced device are PLCs that can count at high speed. (to connect to the encoder)
Two encoders on both sides due to the use of carpets of different dimensions, even small carpets can be inserted from both sides of the device.
Use of remote control drivers to increase or decrease. The washing speed, which can be adjusted according to the type of carpet and the time required for washing, and also due to the lack of initial starters when the engine starts, electricity consumption is also optimized.
Using digital sensors for Measuring the position of the carpet and adjusting the height of the washing brushes, these sensors are installed next to the pulley, and every time the motor rotates, a pulse is determined according to the position of the pulley, and finally the desired position is determined due to the use of a digital sensor instead of an encoder. (pulse counter) we reduced the total price of the machine.
Finally, due to the automaticity of the whole process, human error is avoided and also the number of manpower used for washing is reduced by 70%, which improves the quality and speed of washing. It has increased by far, and according to the stages of the whole process, water wastage will be prevented and ultimately the environment will be helped.
