Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically to a spraying device for steel structure processing that is easy to clean. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates, and are treated with rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to corrosion; therefore, during the production process, they require the application of waterproof and rust-proof coatings to improve their corrosion resistance.

[0003] In existing technologies, when spraying steel structures, some slag easily adheres to the surface of the steel structure. During spraying, the paint tends to adhere to the slag. When the slag falls off, it can expose the area, affecting the quality of the spraying. To address this, we propose a spraying device for steel structure processing that is easy to clean. Utility Model Content

[0004] The purpose of this utility model is to provide a spraying device for steel structure processing that is easy to clean, so as to solve the problem mentioned in the background art that, because some slag easily adheres to the surface of steel structures, the paint tends to adhere to the slag during spraying, and when the slag falls off, the area is easily exposed, which affects the quality of the spraying.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for easy cleaning of steel structure processing, comprising a chain conveyor, a mounting frame, a fixing frame, a cleaning mechanism, a reciprocating moving mechanism, and a spray head.

The cleaning mechanism includes an electric telescopic rod that passes through and is fixed to the top center of the mounting frame. The output shaft of the electric telescopic rod is fixed with a connecting plate. A housing is fixed at the bottom center of the connecting plate. Through slots are opened on both sides of the housing. A sliding plate slides inside the housing. L-shaped rods are fixed at the center of both sides of the sliding plate. A connecting rod is fixed at the bottom center of the sliding plate. A circular plate is fixed at the bottom center of the connecting rod. A rubber head is glued to the bottom of the circular plate. A compression spring is fixed at the top center of the sliding plate. A motor base is fixed at the bottom edge of the connecting plate. A dual-axis motor is fixed at the bottom of the motor base. A first turntable is fixed at the output shaft end of the dual-axis motor. A connecting shaft is fixed at one side edge of the first turntable.

[0007] The cleaning mechanism also includes an air pipe that passes through and is fixed to the other side of the top of the connecting plate, and an air jet box is fixed to the outlet end of the air pipe.

[0008] As a further description of the above technical solution:

[0009] The slide plate slides inside the housing, and the outer side wall of the slide plate is in contact with the inner side wall of the housing.

[0010] As a further description of the above technical solution:

[0011] The L-shaped rod slides inside the through slot, and the input end of the electric telescopic rod and the dual-axis motor are electrically connected to the output end of an external power source.

[0012] As a further description of the above technical solution:

[0013] The reciprocating moving mechanism includes a drive motor fixed to the top center of the fixed frame, a second turntable fixed to the end of the output shaft of the drive motor, a pressing shaft fixed to the bottom edge of the second turntable, slide rods symmetrically fixed to the top of the two sides inside the fixed frame, a sliding seat sliding on the outer side of the slide rod, and a force-bearing groove opened on the top of the sliding seat.

[0014] As a further description of the above technical solution:

[0015] The input end of the drive motor is electrically connected to the output end of an external power supply, and the nozzle is fixed to the bottom of the sliding seat.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the extrusion shaft fits against the side wall of the force groove, and the deflection circumference diameter of the extrusion shaft is smaller than the length of the force groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This easy-to-clean steel structure processing spraying device involves activating the electric telescopic rod to bring the rubber head into contact with the steel structure, connecting the high-pressure air source to the air pipe, and starting the dual-axis motor to drive the first turntable to rotate, causing the connecting shaft to move in a circular motion. When the connecting shaft presses against the L-shaped rod, the sliding plate rises, causing the connecting rod to lift the rubber head and simultaneously compress the compression spring. When the connecting shaft separates from the L-shaped rod, the rubber head returns to its original position through the reset of the compression spring, striking the steel structure and generating vibration to dislodge scum. The high-pressure gas ejected from inside the air jet box blows away the scum, facilitating the cleaning of the steel structure and preventing scum from adhering to the steel structure, ensuring a clean surface, improving spraying quality, and preventing paint from being sprayed onto the scum during subsequent spraying, which would cause the scum to fall off and affect the spraying quality.

[0020] 2. This easy-to-clean steel structure processing spraying device, through the start of the drive motor, drives the second turntable to rotate, thereby causing the extrusion shaft to move in a circular motion, which in turn extrudes the side wall of the force groove, causing the sliding seat to move back and forth on the outside of the slide rod, thereby driving the spray head to move back and forth, increasing the spraying range, avoiding spraying dead corners, and improving the quality of spraying.

Please refer to [link to relevant documentation]. Figure 1 It includes a chain conveyor 100, a mounting frame 200, a fixing frame 300, a cleaning mechanism 400, a reciprocating moving mechanism 500, and a nozzle 600;

[0031] Please refer to it again. Figure 1 The chain conveyor 100 is used to install the mounting frame 200, the fixing frame 300, the cleaning mechanism 400, the reciprocating moving mechanism 500, and the nozzle 600;

[0032] Please refer to it again. Figure 1 and Figure 4 The mounting frame 200 is fixed to the top edge of the chain conveyor 100, the fixing frame 300 is fixed to the top middle of the chain conveyor 100, the cleaning mechanism 400 is connected to the inside of the mounting frame 200, the reciprocating moving mechanism 500 is connected to the inside of the fixing frame 300, the nozzle 600 is connected to the bottom of the reciprocating moving mechanism 500, and the inlet end of the nozzle 600 is fixed with a connecting pipe 610.

[0033] Please refer to it again. Figure 2 The cleaning mechanism 400 includes an electric telescopic rod 410 that is fixed through the middle of the top of the mounting frame 200. A connecting plate 420 is fixed to the end of the output shaft of the electric telescopic rod 410. A housing 430 is fixed to the middle of the bottom of the connecting plate 420. Through slots 431 are provided on both sides of the housing 430. A sliding plate 440 slides inside the housing 430.

[0034] Please refer to it again. Figure 3 L-shaped rods 441 are fixed to the middle of both sides of the skateboard 440. A connecting rod 450 is fixed to the middle of the bottom of the skateboard 440. A round plate 451 is fixed to the middle of the bottom of the connecting rod 450. A rubber head 452 is glued to the bottom of the round plate 451. A compression spring 460 is fixed to the middle of the top of the skateboard 440.

[0035] Please refer to it again. Figure 3 A motor base 470 is fixed to the bottom edge of the connecting plate 420, a dual-axis motor 471 is fixed to the bottom of the motor base 470, a first turntable 480 is fixed to the end of the output shaft of the dual-axis motor 471, and a connecting shaft 481 is fixed to one side of the first turntable 480.

[0036] In summary, starting the electric telescopic rod 410 brings the rubber head 452 into contact with the steel structure. Connecting the high-pressure air source to the air pipe 490 activates the dual-axis motor 471, driving the first turntable 480 to rotate. This causes the connecting shaft 481 to rotate. When the connecting shaft 481 presses against the L-shaped rod 441, the sliding plate 440 rises, causing the connecting rod 450 to lift the rubber head 452. Simultaneously, this presses against the compression spring 460. When the connecting shaft 481 separates from the L-shaped rod 441, the rubber head 452 returns to its original position through the reset of the compression spring 460. This causes the rubber head 452 to vibrate and dislodge the scum. The high-pressure gas ejected from the jet box 491 then blows away the scum, facilitating cleaning of the steel structure and preventing scum from adhering to it. This ensures a clean surface, improves coating quality, and prevents paint from being sprayed onto the scum during subsequent coating processes, which could cause the scum to fall off and affect the coating quality.

[0037] Please refer to it again. Figure 2 The cleaning mechanism 400 also includes an air pipe 490 that passes through and is fixed to the other side of the top of the connecting plate 420, and an air jet box 491 is fixed to the outlet end of the air pipe 490.

[0038] Please refer to it again. Figure 3 The slide plate 440 slides inside the housing 430, and the outer side wall of the slide plate 440 is in contact with the inner side wall of the housing 430.

[0039] Please refer to it again. Figure 2 The L-shaped rod 441 slides inside the through slot 431, and the input end of the electric telescopic rod 410 and the dual-axis motor 471 are electrically connected to the output end of the external power supply.

[0040] Please refer to it again. Figure 4 and Figure 5 The reciprocating moving mechanism 500 includes a drive motor 510 fixed to the top center of the fixed frame 300. A second turntable 520 is fixed to the end of the output shaft of the drive motor 510. A pressing shaft 530 is fixed to the bottom edge of the second turntable 520. Slide rods 540 are symmetrically fixed to the top of both sides inside the fixed frame 300. A sliding seat 550 slides on the outside of the slide rod 540. A force-receiving groove 560 is opened on the top of the sliding seat 550.

[0041] Please refer to it again. Figure 4 The input terminal of the drive motor 510 is electrically connected to the output terminal of the external power supply, and the nozzle 600 is fixed to the bottom of the sliding seat 550.

[0042] Please refer to it again. Figure 5 The outer wall of the extrusion shaft 530 is in contact with the side wall of the force groove 560, and the deflection circumference diameter of the extrusion shaft 530 is smaller than the length of the force groove 560.

[0043] In summary, by starting the drive motor 510, the second turntable 520 is driven to rotate, thereby causing the extrusion shaft 530 to move in a circular motion, which in turn extrudes the side wall of the force groove 560. This causes the sliding seat 550 to move back and forth outside the slide rod 540, thereby driving the spray head 600 to move back and forth, increasing the spraying range, avoiding spraying dead corners, and improving the quality of spraying.

[0044] In practical use, those skilled in the art connect the electrical components to an external power supply and control switch, connect the connecting pipe 610 to the external coating output equipment, place the steel structure on the conveyor belt of the chain conveyor 100, start the electric telescopic rod 410 so that the rubber head 452 contacts the steel structure, connect the high-pressure air source to the air pipe 490, start the dual-shaft motor 471 to drive the first turntable 480 to rotate, causing the connecting shaft 481 to rotate. When the connecting shaft 481 presses against the L-shaped rod 441, the slide plate 440 rises, thereby causing the connecting rod 450 to drive the rubber head 452 to rise, and at the same time press the compression spring 460. When the connecting shaft 481 separates from the L-shaped rod 441, the rubber head 452 is released by the return of the compression spring 460. The nozzle 452 is reset, and the steel structure is tapped to generate vibration, causing the scum to fall off. High-pressure gas ejected from the air jet box 491 blows away the scum, making it easier to clean the steel structure and preventing the scum from adhering to it. The chain conveyor 100 is started to transport the steel structure while cleaning. When the steel structure is at the bottom of the nozzle 600, the paint is fed into the nozzle 600 for spraying. At the same time, the drive motor 510 is started, which drives the second turntable 520 to rotate, thereby causing the extrusion shaft 530 to move in a circular motion, which in turn extrudes the side wall of the force groove 560. This causes the sliding seat 550 to move back and forth outside the slide rod 540, thereby driving the nozzle 600 to move back and forth, increasing the spraying range.
