Specific implementation mode

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Embodiment: As Figures 1-5 shown, the present invention provides a technical solution for an automated equipment for removing red rust on the surface of a board, including an assembly table 1. On both sides of the top of the assembly table 1, adjustment chutes 2 are installed. At both ends inside the adjustment chutes 2, adjustment sliders 4 are slidably connected. At the top of two adjacent adjustment sliders 4, baffles 3 are connected. At the bottom of the opposite surfaces of the two baffles 3, conveying rollers 6 are evenly rotatably installed. The conveying rollers 6 between the opposite surfaces of the two baffles 3 are staggered. At the bottom inside the adjustment chutes 2, rolling wheels 5 are evenly rotatably installed. The top of the rolling wheels 5 contacts the bottom surface of the adjustment sliders 4, converting sliding friction into rolling friction, making it easier for the adjustment sliders 4 to move inside the adjustment chutes 2. The longitudinal cross-section of the adjustment sliders 4 is in the shape of a "work" character, enabling the adjustment sliders 4 to move stably inside the adjustment chutes 2. On the opposite surfaces of the baffles 3, guiding rollers 12 are evenly rotatably installed. At the bottom of one side of the baffle 3, a gearbox 7 is installed. At one end of the gearbox 7, a conveying motor 8 is installed. The output end of the conveying motor 8 is connected to the input end of the gearbox 7. The output end of the gearbox 7 is connected to the rotating shaft of the adjacent conveying roller 6. Under the connection and driving action of the gearbox 7, the conveying motor 8 can drive all the conveying rollers 6 on one side to rotate, facilitating the control of the conveying rollers 6;

[0026] In the middle of one side of the baffle 3, communication ports 13 are evenly penetrated. Outside the two communication ports 13 at one end of the baffle 3, a sandblasting box 14 is installed. Inside the sandblasting box 14, sandblasting guns 15 are evenly rotatably installed. One end of the sandblasting gun 15 is connected to one end of a conveying pipe 16. The other end of the conveying pipe 16 is connected to the output end of an external water sandblaster. A collection box 26 is placed at the bottom of the assembly table 1. The collection box 26 can collect the sprayed water and sand, preventing the water and sand from falling everywhere;

[0027] A swing gear 17 is connected between the rotating shafts of two adjacent sandblasting guns 15. One side of the baffle 3 is located in the middle of two adjacent sandblasting boxes 14, and a lifting electric push rod 19 is installed. The output end of the lifting electric push rod 19 is connected with a swing rack 18, and the swing rack 18 meshes with the adjacent swing gear 17;

[0028] The middle of the bottom of the baffle 3 is connected with a connecting ear 9. The middle of the top of the assembly table 1 is rotatably installed with a bidirectional screw rod 10. The two ends of the bidirectional screw rod 10 are respectively connected with the two connecting ears 9 through threads. One side of the middle of the assembly table 1 is installed with an adjusting motor 11. The output end of the adjusting motor 11 is connected with one end of the bidirectional screw rod 10. Under the connection and driving action of the bidirectional screw rod 10 and the connecting ear 9, the adjusting motor 11 can drive the baffles 3 on both sides to approach or move away from each other;

[0029] On the outer sides of the two communication ports 13 at the other end of the baffle 3, a drying box 20 is installed. Inside the drying box 20, a blast tube 21 is evenly and rotatably installed. Inside the blast tube 21, a heating wire 22 is installed. The input ends of the conveying motor 8, the adjusting motor 11, the lifting electric push rod 19 and the heating wire 22 are electrically connected to the output end of an external controller, and the input end of the external controller is electrically connected to the output end of an external power supply. Through the external controller, each electrical component can be controlled, which is convenient for the automatic control of the equipment. On one side of the baffle 3 corresponding to one side of the drying box 20, a gas collecting box 23 is installed. A gas conveying hose 24 is connected between one end of the blast tube 21 and the adjacent gas collecting box 23. A linkage rod 25 is connected between the rotating shaft of the sandblasting gun 15 and the blast tube 21. A linkage rod 25 is also connected between the rotating shafts of two adjacent blast tubes 21.

[0030] Working principle and usage process of the utility model: When in use, first, adjust the distance between the baffle plates 3 according to the thickness of the plate to be processed. Start the adjustment motor 11, and the adjustment motor 11 drives the bidirectional screw 10 to rotate. Under the connection and driving action between the bidirectional screw 10 and the connecting ear 9 and the sliding connection between the adjustment slider 4 and the adjustment chute 2, the adjustment motor 11 drives the adjustment baffle plate 3 to move, so that the distance between the conveying rollers 6 on both sides of the two baffle plates 3 can hold the plate. Place the plate on the conveying rollers 6, start the conveying motor 8, and the conveying motor 8 drives the conveying rollers 6 to rotate. The conveying rollers 6 drive the plate to move. The plate first passes through the position of the sandblasting gun 15. The lifting electric push rod 19 and the external water sandblaster are started. The mixture of water and sand is sprayed out from the spraying end of the sandblasting gun 15. The sprayed water sand acts on both sides of the plate, and the red rust on both sides of the plate is removed under the impact of the water sand. After the red rust is removed, the mixed water sand falls into the interior of the collection box 26. At the same time, the lifting electric push rod 19 is started, and the lifting electric push rod 19 drives the swing rack 18 to move up and down. The swing rack 18 drives the swing gear 17 to rotate reciprocally, and then drives the sandblasting gun 15 to swing, increasing the spraying range of the sandblasting gun 15, avoiding the generation of dead corners for red rust removal, and making the red rust removal effect better. Under the impact of the water sand, while the red rust on both sides of the plate can be removed, the dirt on the surface of the plate can also be cleaned, without the need to use a water gun for subsequent flushing, and the processing efficiency is high;

[0031] After the red rust is removed, the conveying rollers 6 drive the plate to continue moving. When the plate moves to the position of the air blower cylinder 21, the external air pump and the heating wire 22 are started. The external air pump conveys air into the air collection box 23, and then flows through the air collection box 23 and the air delivery hose 24 and is conveyed into the air blower cylinder 21. When the conveyed gas flows through the interior of the air blower cylinder 21, it is heated by the heating wire 22 and sprayed towards both sides of the plate. The sprayed hot air dries the plate and removes the water droplets on the surface of the plate. At the same time, under the connection and driving action of the linkage rod 25, the lifting electric push rod 19 drives the air blower cylinder 21 to swing, increasing the blowing range of the air blower cylinder 21, avoiding the generation of blowing dead corners, and making the drying effect better.

[0032] Finally, it should be noted that the above are only preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
