[0035] The working principle of the screen printing equipment provided by the present invention is as follows: when the equipment needs to be used to print on a steel drum, the servo motor 5 is first started to drive the roller to rotate, the roller drives the conveyor belt 6 to rotate, and the conveyor belt 6 drives the placement plate 7 to move. When the steel drum needs to be transferred to the placement plate 7, the drive motor 306 is first started to drive a screw rod 302 to rotate, the screw rod 302 drives the reel, and the reel uses the belt 304 to make the two screw rods 302 rotate synchronously, and the screw rod 302 drives the connecting plate 307, so that the connecting plate 307 moves downward along the inner wall of the connecting frame 301. The connecting plate 307 drives the fixing seat 308, and the fixing seat 308 drives the connecting plate 309 and the carrying plate 310 to move toward the ground. When the carrying plate 310 moves to the appropriate position, the motor 311 is started to drive the connecting plate 309, so that the connecting plate 309 rotates along the inner wall of the fixing seat 308. When the connecting plate 309 drives the carrying plate 310, so that the rounded side of the carrying plate 310 contacts the ground, the personnel pushes the steel drum onto the carrying plate 310, and then starts the driving motor 306 to drive the two screw rods 302 to rotate in the opposite direction. 302 drives the connecting plate 307 to move upward. When the supporting plate 310 drives the steel barrel to rise to a suitable height, the motor 311 is started to drive the connecting plate 309, so that the connecting plate 309 drives the supporting plate 310 and the steel barrel to rotate in the direction close to the conveyor belt 6. When the supporting plate 310 is tilted to a certain angle, the steel barrel on the supporting plate 310 will slide onto the placement plate 7. The placement plate 7 will drive the steel barrel to move to the bottom of the screen printing machine 8, so that the surface of the steel barrel can be printed. In the process of the connecting plate 309 rotating along the inner wall of the fixed seat 308, The sliding rod 313 fixed on the connecting plate 309 will slide along the inner wall of the sliding hole 312, which can improve the stability of the connecting plate 309 during the rotation process, and can prevent the connecting plate 309 from rotating too much and causing the steel barrel on the supporting plate 310 to fall. In addition, by rounding one side of the supporting plate 310, the steel barrel can be easily transferred from the ground to the supporting plate 310. Finally, by making the screw rod 302 into stainless steel, the oxidation rate of the screw rod 302 can be reduced, thereby increasing the service life of the screw rod 302.

[0036] When the cleaning brush 47 is moved, the guide rod 46 can guide and position it, thereby preventing the cleaning brush 47 from rotating and shifting during the cleaning process.

[0037] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
