Description

Technical Field

[0001] This invention relates to the field of steel component processing technology, and in particular to a steel component painting device. Background Technology

[0002] Steel pipe components are commonly used as supporting elements in buildings, bridges, and other engineering structures. They can withstand gravity and loads, and provide stability and strength. Steel pipe components are also frequently used in support and railing systems, such as stair handrails, balustrades, and safety protection facilities. When steel pipe components are put into actual use, their surfaces need to be painted to prevent external substances from corroding the steel pipes and extend their service life.

[0003] A search revealed Chinese patent CN215542045U, which discloses a painting device for steel component production, including a base, a paint tank, a motor, a placement mechanism, a painting ring, and a pump body. The placement mechanism includes a slide and a placement plate. The motor has an output shaft with a reciprocating threaded groove. The slide has a reciprocating screw hole that meshes with the reciprocating threaded groove. The pump body delivers paint from the paint tank to the painting ring. The inner circumference of the painting ring is uniformly provided with atomizing nozzles.

[0004] This patent uses a placement mechanism to place the steel pipe. The placement mechanism and the steel pipe are reciprocated by the operation of a motor. During this process, each painting ring is fitted on the outside of the steel pipe. The paint is drawn out by the operation of the pump body, and then sprayed around the steel pipe through the atomizing nozzle inside the painting ring. With the movement of the steel pipe, the painting operation can be achieved in all directions.

[0005] However, the above invention has the following shortcomings: The above patent adopts a technical solution of directly spraying paint on the surface of the steel pipe. In order to avoid the presence of rust or foreign objects on the surface of the steel pipe, which would affect the painting effect, it is often necessary to add a pre-processing step to pre-treat the surface of the steel pipe. The pre-processing step also requires loading and unloading the steel pipe, which results in low processing efficiency of the steel pipe.

[0006] Therefore, designing a steel component painting device that can integrate the pretreatment of steel pipes and raise the surface of the steel pipes to generate static electricity before painting, so as to improve the painting effect and drying efficiency, is the primary problem that those skilled in the art should solve.

A driven gear is fixedly installed on a set of abutment rods near the ring frame, and the driven gear meshes with the toothed ring cylinder.

[0012] Preferably, the painting assembly includes a gantry frame fixed to the opposite side of two moving blocks, and a pair of guide rods are fixed at both ends of the top of the main frame, with the gantry frame and the guide rods slidably connected.

[0013] Preferably, a paint storage tank is fixed to the top of the gantry frame, and a side block is fixed to one side of the paint storage tank. A side rod is rotatably mounted on the side block, and a driven gear two is fixedly mounted at the bottom end of the side rod. A rack is fixedly mounted on the guide rod near the side rod, and the rack meshes with the driven gear two.

[0014] Preferably, a central shaft is rotatably mounted at the core of the paint storage tank, and a stirring lever is fixed on the outer peripheral wall of the central shaft. The central shaft and the side rod are together fitted with a transmission belt.

[0015] Preferably, a plurality of equally spaced stirring baffles are fixedly installed on the outer peripheral wall of the central shaft, and a feeding hopper is fixedly connected to the top of the paint storage tank.

[0020] Secondly, after the rust removal operation is completed, the electric telescopic rod can be controlled to retract, causing the arc-shaped brush plate to move downward. In conjunction with the side round rods set on both sides, the movable side plate can be tilted upward. At this time, the rubber pads can contact and rub against multiple rotating steel pipe components in sequence, removing some of the residual rust. At the same time, the friction between the rubber pads and the steel pipe components causes the steel pipe components to heat up and generate static electricity, thereby improving the adsorption effect of the steel pipe components on the paint when the subsequent painting components are painted, and helping to speed up the drying of the paint.

[0021] Thirdly, when the steel pipe component is pre-treated by moving the arc-shaped brush plate, the central shaft can rotate to stir the paint, ensuring the uniformity of the paint during subsequent painting operations, thereby guaranteeing the painting quality of the steel pipe component.

[0033] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides an improved steel component painting device. The technical solution of this invention is as follows:

[0035] like Figures 1 to 8 As shown, this embodiment of the invention provides a steel component painting device, including a support base 1, on which a main frame 2 is fixedly installed. The support base 1 and the main frame 2 constitute the main support part of the device, and also includes;

[0036] The clamping assembly is installed on the main frame 2. The clamping assembly is used to clamp multiple steel pipe components and can drive multiple steel pipe components to rotate, while also causing multiple steel pipe components to rotate themselves.

[0037] The pretreatment component is located between the support base 1 and the main frame 2. The pretreatment component includes a through slot 203 at the bottom of the main frame 2, with T-shaped brackets 903 slidably connected to both ends of the through slot 203 in the vertical direction. A pair of lead screws 901 are rotatably mounted between the two T-shaped brackets 903, and each lead screw 901 is threadedly connected to a moving block 905. An arc-shaped brush plate 6 is fixedly connected to the top of both moving blocks 905. The arc-shaped brush plate 6 has a cavity 601 inside, and multiple sets of equally spaced steel brushes 603 are fixedly mounted on its surface. The surface of the arc-shaped brush plate 6 also has multiple strip-shaped through slots 6 that are staggered with the steel brushes 603. 02. Side round rods 606 are rotatably installed on both sides of the main frame 2 near the lead screw 901. Movable side plates 604 are rotatably installed on both ends of the arc-shaped brush plate 6 via hinges. Rubber pads 605 are fixed on the surface of the movable side plates 604. Electric telescopic rods 9 are fixed between the top outer wall of the support base 1 and the two T-shaped frames 903. When the steel pipe component rotates and rotates, the electric telescopic rods 9 can be extended by controlling the start of the extension, so that the steel brushes 603 on the arc-shaped brush plate 6 come into contact with the surfaces of multiple rotating steel pipe components, thereby achieving the grinding treatment of the surface of the steel pipe component, thereby removing the rust on the surface of the steel pipe component, and ensuring that the anti-corrosion paint sprayed subsequently adheres firmly to the surface of the steel pipe component.

[0038] On the other hand, after the rust removal operation is completed, the electric telescopic rod 9 can be controlled to retract, causing the arc-shaped brush plate 6 to move downward. In conjunction with the side round rods 606 set on both sides, the movable side plate 604 can be tilted upward. At this time, the rubber pads 605 can contact and rub against multiple rotating steel pipe components in sequence, removing some of the residual rust. At the same time, the friction between the rubber pads 605 and the steel pipe components causes the steel pipe components to heat up and generate static electricity, thereby improving the adsorption effect of the steel pipe components on the paint when the subsequent painting components are painted, and helping to speed up the drying of the paint.

[0039] The negative pressure component is installed on the support base 1. When the steel brush 603 removes rust from the surface of the steel pipe component, the negative pressure component can be used in conjunction with the strip groove 602 to remove the dust generated during the rust removal process and ensure the air quality at the processing site.

[0040] The painting assembly is located above the main frame 2 and is used to paint the surfaces of multiple steel pipe components.

[0041] Furthermore, a transmission belt 902 is fitted onto one end of both lead screws 901. One of the lead screws 901 is fixedly connected to a rotary motor 904, which is fixed to an adjacent T-shaped frame 903. With the above structure, when the rotary motor 904 is running, the transmission belt 902 can drive the two lead screws 901 to rotate, and the moving block 905 can drive the arc-shaped brush plate 6 to move, so as to ensure the grinding of the surface of the long steel pipe component.

[0042] As a further embodiment of the present invention, the clamping assembly includes an extension shaft 505 and a hydraulic rod 201. The extension shaft 505 is rotatably mounted on one side of the main frame 2, and the hydraulic rod 201 is fixedly mounted on the other side of the main frame 2. The extension shaft 505 and the hydraulic rod 201 are coaxially arranged. A connecting block 202 is rotatably mounted on the end of the hydraulic rod 201. A ring frame 5 and a ring frame 204 are fixedly connected to the extension shaft 505 and the connecting block 202, respectively. A set of abutment rods 502 are rotatably mounted on both the ring frame 5 and the ring frame 204. With the above structure, after one end of multiple steel pipe components is inserted into a set of abutment rods 502, the hydraulic rod 201 can be controlled to move, thereby pushing the ring frame 204 and another set of abutment rods 502 to move, and using the other set of abutment rods 502 to achieve contact and fixation of multiple steel pipe components.

[0043] Furthermore, a driven gear 506 is fixed to the outer peripheral wall of one end of the extension shaft 505, and a drive motor 507 is fixed to the outer peripheral wall of one end of the main frame 2. A drive gear 508 that meshes with the driven gear 506 is fixedly installed on the output shaft of the drive motor 507. A gear ring cylinder 501 coaxially arranged with the ring frame 5 is fixedly installed on one side of the main frame 2. A driven gear 503 is fixedly installed on a set of abutment rods 502 near the ring frame 5. 503 meshes with the toothed ring cylinder 501; through the above structure, when processing the steel pipe components, the drive motor 507 can be controlled to start, and under the action of the drive gear 508 and the driven gear disc 506, the extension shaft 505 and the ring frame 5 will rotate. When a set of abutment rods 502 rotate with the ring frame 5, the set of abutment rods 502 and multiple steel pipe components themselves can rotate through the meshing action of the driven gear 503 and the toothed ring cylinder 501.

[0044] Furthermore, the painting assembly includes a gantry 8 fixed to the opposite side of the two moving blocks 905, and a pair of guide rods 4 are fixed at both ends of the top of the main frame 2. The gantry 8 is slidably connected to the guide rods 4. When the moving blocks 905 move, they can drive the gantry 8 to move. The guide rods 4 can guide and support the movement of the gantry 8 and improve the stability of the gantry 8 when it moves.

[0045] Furthermore, a paint storage tank 3 is fixed to the top of the gantry frame 8, and a side block is fixed to one side of the paint storage tank 3. A side rod 307 is rotatably mounted on the side block, and a driven gear 308 is fixedly mounted at the bottom of the side rod 307. A rack 401 is fixedly mounted on the guide rod 4 near the side rod 307, and the rack 401 meshes with the driven gear 308. When the gantry frame 8 moves, it can drive the paint storage tank 3 and the side rod 307 to move. During this process, the driven gear 308 rotates along the rack 401 and drives the side rod 307 to rotate.

[0046] Furthermore, a central shaft 302 is rotatably mounted at the core of the paint storage tank 3, and a stirring lever 309 is fixed on the outer peripheral wall of the central shaft 302. The central shaft 302 and the side rod 307 are together fitted with a transmission belt 306.

[0047] Furthermore, multiple equidistant stirring baffles 309 are fixedly installed on the outer peripheral wall of the central shaft 302, and the top of the paint storage tank 3 is fixedly connected to the feeding hopper 301; through the above structure, when the side rod 307 rotates, it can drive the central shaft 302 to rotate through the transmission belt 306, and use the stirring baffles 309 to stir the material in the paint storage tank 3.

[0048] In summary, when the arc-shaped brush plate 6 moves to pre-treat the steel pipe component, this application enables the central shaft 302 to rotate and stir the paint. This ensures the uniformity of the paint during subsequent painting operations, thereby guaranteeing the painting quality of the steel pipe component.

[0049] As a further embodiment of the present invention, a material pump 303 is fixedly connected to the bottom side wall of the top of the gantry frame 8, and the input end of the material pump 303 is fixedly connected to the paint storage tank 3. The output end of the material pump 303 is fixedly connected to the arc-shaped cavity tube 304, and the arc-shaped cavity tube 304 is fixedly connected to the gantry frame 8. Multiple equally spaced nozzles 305 are fixedly connected to the bottom side wall of the arc-shaped cavity tube 304. When the painting operation is performed, the electric telescopic rod 9 is lowered to half. At this time, the arc-shaped brush plate 6 and the movable side plate 604 will not contact the steel pipe components. When painting, the material pump 303 is started, and the paint is sprayed out through the arc-shaped cavity tube 304 and multiple nozzles 305. With the rotation of multiple steel pipe components, uniform painting of the steel pipe components is achieved.

[0050] Furthermore, the negative pressure assembly includes a filter box 7 fixedly installed on the top outer wall of the support base 1, and a negative pressure pump 701 is fixedly connected to one end of the filter box 7. A connecting pipe 607 is fixedly connected to the bottom middle of the arc-shaped brush plate 6. In order to avoid interference between the arc-shaped brush plate 6 and the filter box 7, a corrugated hose 702 is fixedly connected between the end of the connecting pipe 607 and the filter box 7. When the negative pressure pump 701 is running, it can put the cavity 601 in the arc-shaped brush plate 6 into a negative pressure state through the connecting pipe 607 and the corrugated hose 702 to remove the dust generated by rust removal.

[0051] The specific working method is as follows: When in use, after inserting one end of multiple steel pipe components into a set of abutment rods 502, the hydraulic rod 201 can be controlled to run, which pushes the ring frame 2 504 and another set of abutment rods 502 to move, and the other set of abutment rods 502 is used to abut and fix the multiple steel pipe components; when processing the steel pipe components, the drive motor 507 can be started, and under the action of the drive gear 508 and the driven gear disc 506, the extension shaft 505 and the ring frame 1 5 will be rotated. When a set of abutment rods 502 rotates with the ring frame 1 5, the meshing action of the driven gear 1 503 and the gear ring cylinder 501 can make the set of abutment rods 502 and the multiple steel pipe components themselves rotate;

[0052] When the steel pipe component rotates and spins, the electric telescopic rod 9 can be extended by control, allowing the steel brush 603 on the arc-shaped brush plate 6 to contact the surfaces of multiple rotating steel pipe components, thereby achieving a grinding treatment on the surface of the steel pipe component, removing rust, and ensuring that the subsequently sprayed anti-corrosion paint adheres firmly to the surface of the steel pipe component. While the steel brush 603 is removing rust from the surface of the steel pipe component, a negative pressure component can be used in conjunction with the strip-shaped through-channel 602 to remove the dust generated during the rust removal process, ensuring the air quality at the processing site; another... In terms of rust removal, after the rust removal operation is completed, the electric telescopic rod 9 can be controlled to retract, causing the arc-shaped brush plate 6 to move downward. In conjunction with the side round rods 606 set on both sides, the movable side plate 604 is raised upward. At this time, the rubber pads 605 set on the rods contact and rub against multiple rotating steel pipe components in sequence, removing some of the residual rust. At the same time, through the friction between the rubber pads 605 and the steel pipe components, the steel pipe components are heated and generate static electricity, thereby improving the adsorption effect of the steel pipe components on the paint when the subsequent painting components are painted, and helping to speed up the drying of the paint.

[0053] When the rotary motor 904 is running, the transmission belt 902 drives the two lead screws 901 to rotate, and the moving block 905 drives the arc-shaped brush plate 6 to move, ensuring the grinding of the surface of the long steel pipe component. When the moving block 905 moves, it drives the gantry 8 to move. The guide rod 4 guides and supports the movement of the gantry 8 and improves the stability of the gantry 8 during movement. When the gantry 8 moves, it drives the paint storage tank 3 and the side rod 307 to move. During this process, the driven gear 308 rotates along the rack 401 and drives the side rod 307 to rotate. When the side rod 307 rotates, the transmission belt 306 drives the central shaft 302 to rotate, and the stirring rod 309 stirs the material in the paint storage tank 3. When the arc-shaped brush plate 6 moves to pre-treat the steel pipe component, the central shaft 302 rotates to stir the paint, thereby ensuring the painting quality of the steel pipe component.

[0054] During the painting operation, the electric telescopic rod 9 is lowered to halfway. At this time, the arc-shaped brush plate 6 and the movable side plate 604 will not contact the steel pipe components. When painting, the material pump 303 is started, and the paint is sprayed out through the arc-shaped cavity pipe 304 and multiple nozzles 305. With the rotation of multiple steel pipe components, the steel pipe components are evenly painted.

[0055] The foregoing description enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
