Automatic photoelectric sensor cleaning device

[0021] combine figure 1 and image 3 As shown, the present invention consists of an electromagnetic airflow valve 1, an end bracket 2, a flow valve 4, a gas pipe 5, a shunt pipe 6, and an air pressure detector 7.

[0022] The air inlet and the air outlet of the electromagnetic airflow valve 1 are respectively connected with air pipes 5, and the electromagnetic airflow valve 1 is connected with the computer control system of the production workshop. Electromagnetic air flow valve 1 controls the air flow of the entire pipeline system. In the computer control system, the electromagnetic airflow valve 1 is provided with a timing program. Every once in a while, preferably 15 minutes, the electromagnetic airflow valve 1 is opened, and the compressed air is introduced in the air pipe 5. The shunt pipe 6 is a three-way shunt air pipe, the left end is sleeved with the air pipe 5 , the middle end leads to an end support 2 , and the right end is sleeved with the air pipe 5 connected to th

[0025] combine figure 2 and image 3 As shown, the present invention consists of an electromagnetic airflow valve 1, an end bracket 2, a flow valve 4, a gas pipe 5, a shunt pipe 6, and an air pressure detector 7.

[0026] Both ends of the flow valve 4 are respectively connected to the air pipe 5 , the left end leads to compressed air, and the right end leads to the first shunt pipe 6 . By adjusting the flow valve 4, the size of the airflow blowing to the photoelectric sensor probe 32 after the airflow is conducted can be controlled. The shunt pipe 6 is a three-way shunt air pipe, the left end is sleeved with the air pipe 5 , the middle end leads to an end bracket 2 , and the right end is sleeved with the air pipe 5 connected to the next shunt pipe 6 . An electromagnetic airflow valve 1 is provided between the end bracket 2 and the shunt pipe 6 . Electromagnetic airflow valve 1 is connected to the computer control system of the production workshop.
