Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a photoelectric sensor reflector protective device. Background Art

[0002] The centering reflector on the uncoiler's centering device, used in conjunction with a photoelectric sensor, measures 95 cm long and 10 cm wide. Manufacturing is complex and expensive. The original design, designed to be mounted directly on the equipment's baseplate, exposed rolling oil to splashing onto the reflector during production. Due to the highly corrosive nature of rolling oil, the reflector quickly corroded and damaged, resulting in poor overall performance. Consequently, this utility model proposes a protective device for a photoelectric sensor reflector. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and to provide a photoelectric sensor reflector protective device, which has the characteristics of good protective effect and safe and reliable use.

[0004] In order to solve the above technical problems, the purpose of the present invention is achieved as follows: the present invention involves a photoelectric sensor reflector protective device, including a protective cover in the shape of a long groove, a photoelectric sensor reflector is attached to the inner bottom of the protective cover, and the cover opening of the protective cover is provided with a protective plate for blocking the photoelectric sensor reflector, and the protective plate is translucent.

[0005] The utility model is further configured as follows: a valve block is provided at least at one end outside the protective cover, the valve block has an air supply channel, the valve block is provided with an air inlet pipe communicating with one end of the air supply channel, and an air outlet pipe communicating with the other end of the air supply channel, and the air outlet pipe is a bendable and shapeable pipe.

[0006] The utility model is further configured as follows: a duck claw-shaped flat air nozzle is provided at one end of the air outlet pipe that is not connected to the valve block.

[0007] The utility model is further configured as follows: valve blocks are provided at both ends outside the protective cover.

[0008] The utility model is further configured as follows: a positive pressure inlet is provided on the protective cover, and the positive pressure inlet is connected to an air supply device for providing positive pressure to the interior of the protective cover.

[0009] The utility model is further configured as follows: the protective plate is a transparent PVC plate.

[0010] In summary, the present invention has the following beneficial effects:

[0011] 1. The protective cover is combined with a light-transmitting protective plate to isolate the photoelectric sensor reflector from splashing rolling oil without affecting the normal use of the photoelectric sensor reflector, thereby protecting the photoelectric sensor reflector from corrosion and extending the service life of the photoelectric sensor reflector.

[0012] 2. By connecting the air inlet pipe to the positive pressure air source, the air outlet pipe sprays out positive pressure gas and bends it to spray the protective plate to prevent the splashing rolling oil from affecting the light transmittance of the protective plate, thereby cleaning the rolling oil and ensuring the light transmittance of the protective plate.

The protective plate 3 is light-transmitting and is a transparent PVC plate.

[0019] Furthermore, valve blocks 4 are provided at both ends outside the protective cover 1. The valve block 4 has an air supply channel (not shown). The valve block 4 is provided with an air inlet pipe 5 connected to one end of the air supply channel and an air outlet pipe 6 connected to the other end of the air supply channel. The air outlet pipe 6 is a bendable and shapeable pipe.
