[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a surface purging device for electrogalvanized steel plates, comprising a base 1, a cylinder 2 fixed to the front side of the base 1, an output end of the cylinder 2 fixedly connected to an air delivery shell 4, the interior of the air delivery shell 4 is a hollow cavity, a fan 5 is fixedly installed on the top of the air delivery shell 4, a plurality of air nozzles 6 distributed at equal distances are connected to the bottom of the air delivery shell 4, the ends of the air nozzles 6 are inclined to the horizontal plane, a mounting frame 7 is fixedly connected to the front side wall of the air delivery shell 4, a pressing plate 8 is connected to the bottom of the mounting frame 7 through an elastic mechanism, and a rag 9 is fixedly arranged at the bottom of the pressing plate 8.

[0025] When blowing off the surface of the galvanized steel plate, the steel plate is first placed on an external processing table, and then the device is placed on one side of the processing table. The fan 5 is then turned on, and the fan 5 draws external air into the air delivery shell 4, and then discharges it through a plurality of air nozzles 6. The gas generated by the air nozzles 6 is blown onto the surface of the galvanized steel plate to blow off the solid impurities on the surface of the galvanized steel plate. By starting the cylinder 2, the air delivery shell 4 moves in a straight line, driving the air nozzles 6 to move along the surface of the steel plate, thus expanding the scope of blowing off, further improving the cleanliness of the steel plate surface, and avoiding the generation of indentations or holes when the galvanized steel plate is leveled.

[0026] An external driving device can be used to drive the pressing plate 8 down, so that the rag 9 contacts the surface of the galvanized steel plate processing table, and cooperates with the drive of the cylinder 2 to make the rag 9 clean the impurities that are adhered to the surface of the steel plate and are difficult to blow off.

[0027] In order to increase the stability of the gas delivery shell 4 during linear movement, two telescopic rods 3 are fixedly connected between the base 1 and the gas delivery shell 4. The two telescopic rods 3 are symmetrically distributed on both sides of the cylinder 2. The telescopic rods 3 can perform telescopic movements to assist the linear movement of the gas delivery shell 4 and play a role in stabilization and guidance.

[0028] The above-mentioned elastic mechanism includes two guide rods 10 fixed on the top of the pressure plate 8. The upper ends of the guide rods 10 are movably inserted into the mounting frame 7. A spring 11 is sleeved on the guide rods 10. The two ends of the spring 11 are respectively fixedly connected to the mounting frame 7 and the pressure plate 8. The setting of the guide rods 10 can guide the pressure plate 8 so that the pressure plate 8 can only move in the vertical direction; the function of the spring 11 is to drive the pressure plate 8 to reset.

[0029] In order to drive the pressing plate 8 to descend, a driving member for driving the pressing plate 8 to descend is arranged on the top of the mounting frame 7, and an opening 701 corresponding to the position of the driving member is opened in the middle of the mounting frame 7.

[0030] The driving member includes a motor 12 fixed to the top of the mounting bracket 7 and a cam 13 fixed to the output end of the motor 12 . The cam 13 can rotate inside the opening 701 .

[0031] When impurities are stuck on the surface of the galvanized steel sheet and are difficult to blow off, the motor 12 can be started to drive the cam 13 to rotate. The cam 13 squeezes the pressure plate 8, causing the pressure plate 8 to drop, and the rag 9 directly contacts the surface of the galvanized steel sheet. At this time, the rag 9 wipes off the impurities through the push of the cylinder 2, further improving the cleaning effect of the galvanized steel sheet; and when the pressure plate 8 needs to be reset, the motor 12 is started to make the long end of the cam 13 away from the pressure plate 8. At this time, the spring 11 releases the elastic force and pulls the pressure plate 8 upward to reset.

[0032] Finally, in terms of the structural design of the base 1, the base 1 in the device is in an inverted T shape as a whole, so that the bottom support area is large, the stability is high, and it is not easy to tip over.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
