Description

Technical Field

[0001] This invention relates to the field of coating machines, and more particularly to a coating apparatus and method for applying an anti-rust coating to the surface of steel. Background Technology

[0002] A coating machine is an automated device used to uniformly coat liquid or powder materials onto the surface of an object. It is widely used in surface treatment processes in industrial production.

[0003] Existing technologies, such as the invention disclosed in CN103934148A, disclose a coating machine. The key technical points of this machine are as follows: A coating machine has an upper barrel connected to a hollow base. A lifting plate is located inside the upper barrel. A coating cylinder rests on the lifting plate. A bearing seat is fixed at the shaft hole on the top plate of the hollow base. An isolation cylinder is fixed along the shaft hole opening on the bottom plate of the coating cylinder. A bushing is located inside the isolation cylinder. The lower part of the bushing extends out of the lifting plate, and its lower end connects to the bearing seat. The upper part of the bushing extends out of the isolation cylinder, and its upper end is provided with an upper bearing. A main shaft is located inside the bushing and supported by the upper bearing and a lower bearing in the bearing seat. A conical positioning body is provided on the part of the main shaft extending upwards from the bushing. A workpiece basket has a conical cavity with an open bottom surface that matches the conical positioning body of the main shaft. The workpiece basket is connected to the conical positioning body of the main shaft via the conical cavity. The main shaft extends downwards into the hollow base through the bearing seat. The main shaft is driven to rotate by a motor located outside the hollow base via belt drive. The lifting plate is lifted and lowered by a lifting mechanism. This invention has a simple structure and is particularly suitable for experimental or small-batch production.

[0004] Regarding the above-mentioned content, the following technical defects were found: Existing steel surface anti-rust coating devices usually use manual clamps or simple pressure plates to fix the steel. Manual clamps require operators to tighten the bolts one by one with a wrench, which is cumbersome and time-consuming. Moreover, the clamping force depends on the operator's experience. If it is too tight, it will easily cause the steel to deform. If it is too loose, the steel will easily shake during the coating process, resulting in uneven coating thickness and affecting the anti-rust effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a coating device and method for applying an anti-rust coating to the surface of steel.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coating device for anti-rust coating on steel surface, comprising a coating cabinet, a steel body, and a clamping assembly. Several supports are fixedly connected to the lower surface of the coating cabinet. A control panel is fixedly connected to one side of the coating cabinet. A coating nozzle is installed on the top wall of the inner wall of the coating cabinet. The steel body is mounted on the inner wall of the coating cabinet by means of the clamping assembly. The clamping assembly includes a vertical plate, which is fixedly connected to the inner wall of the coating cabinet. A rotating column is rotatably connected to one end of the vertical plate. A fixing plate is fixedly connected to the inner wall of the coating cabinet. The side of the fixing plate closest to the vertical plate rotates... The device is connected by a connecting column. The connecting column and the rotating column are fixedly connected to the same placement plate at their closest ends. The upper surface of the placement plate has a square groove. Two base plates are fixedly connected to the upper surface of the placement plate. Connecting plates are rotatably connected to both sides of the two base plates. The upper surfaces of the two connecting plates are rotatably connected to the same top plate. One side of one of the connecting plates is fixedly connected to a connecting plate. The inner wall of the connecting plate has a vertical groove. Two cylinders are fixedly connected to the upper surface of the placement plate. Pull plates are fixedly connected to the output ends of the two cylinders. The two pull plates are slidably connected to the inner walls of the two vertical grooves, respectively.

[0007] The effect achieved by the above components is as follows: by setting up a clamping assembly, the cylinder pushes the pull plate to slide along the vertical groove, the pull plate drives the connecting plate and the connecting plate to rotate, the connecting plate drives the top plate to descend, and the top plate and the bottom plate cooperate to clamp the steel body from the top and bottom sides, thereby realizing the rapid clamping and fixing of the steel, preventing the steel from shifting during the coating process, and improving the coating uniformity and accuracy.

[0008] Preferably, a sliding plate is slidably connected to the upper surface of the fixed plate, a servo motor is fixedly connected to the upper surface of the sliding plate, a toothed column is fixedly connected to the output end of the servo motor, and a toothed hole is opened on the inner wall of the connecting column, and the toothed column is engaged with the toothed hole.

[0009] The effect achieved by the above components is as follows: the servo motor drives the gear column to rotate, and the gear column drives the connecting column and the placement plate to rotate through the tooth hole, so as to realize the multi-angle flipping coating of the steel, so that the anti-rust coating evenly covers the surface of the steel and improves the coating effect.

[0010] Preferably, a sliding block is fixedly connected to the lower surface of the sliding plate, and a sliding groove is formed on the upper surface of the fixed plate, the sliding groove being adapted to the size of the sliding block.

[0011] The effect achieved by the above components is as follows: the sliding block is slidably connected in the sliding groove, which guides and limits the movement of the sliding plate, ensures that the toothed column accurately engages or disengages from the toothed hole, and realizes the switching between flip drive and locking.

[0012] Preferably, a gasket is fixedly connected to the side of the bottom plate and the top plate that is close to each other. The gasket has a right trapezoidal cross-section and is specifically a rubber gasket.

[0013] The effect achieved by the above components is as follows: the right-angled trapezoidal rubber pad is fixed to the inside of the bottom plate and the top plate. When the top plate descends to clamp the steel, the pad uses the elastic deformation of the rubber to fill the unevenness of the steel surface, increase the friction to prevent slippage, and at the same time avoids damaging the steel surface.

[0014] Preferably, the inner wall of the coating cabinet is provided with a cleaning component, which includes two side plates. The inner walls of the two side plates are rotatably connected to the same screw. An auxiliary plate is threadedly connected to the arc surface of the screw. A crossbar is fixedly connected to the inner wall of the coating cabinet. The arc surface of the crossbar is slidably connected to the auxiliary plate. Two columns are slidably connected to the lower surface of the auxiliary plate. An installation plate is fixedly connected to the lower surface of the two columns. A loading and unloading groove is opened on the lower surface of the installation plate. A cleaning plate is engaged in the inner wall of the loading and unloading groove. Several brushes are fixedly connected to the lower surface of the cleaning plate.

[0015] The effect achieved by the above components is as follows: by setting up the cleaning components, the screw rotation drives the auxiliary plate to move along the crossbar, the auxiliary plate drives the column and mounting plate to move, the mounting plate drives the cleaning plate and brush to move, and the brush cleans the inner wall of the coating cabinet, removes residual paint, and keeps the equipment clean.

[0016] Preferably, springs are fitted onto the arc surfaces of the two columns, and the two ends of the springs are fixedly connected to the auxiliary plate and the mounting plate, respectively.

[0017] The effect achieved by the above components is as follows: the spring is sleeved on the arc surface of the column, and its two ends are fixedly connected to the auxiliary plate and the mounting plate respectively. The elastic force of the spring keeps the brush in elastic contact with the inner wall of the coating cabinet, improving the cleaning effect, while buffering the collision between the brush and the inner wall.

[0018] Preferably, a drive motor is fixedly connected to the inner wall of the coating cabinet, and the output end of the drive motor is fixedly connected to one end of the screw.

[0019] The effect achieved by the above components is that the drive motor drives the screw to rotate, providing automated power for the movement of the cleaning components, realizing automatic cleaning of the inner wall of the coating cabinet, which is more labor-saving and efficient than manual cleaning.

[0020] Preferably, a storage assembly is provided on one side of the coating cabinet. The storage assembly includes a cabinet door and a storage box. The cabinet door is rotatably connected to one side of the coating cabinet. Two handles are fixedly connected to one side of the cabinet door. Side columns are fixedly connected to both sides of the storage box. The side columns are slidably connected to the inner wall of the coating cabinet. Two connecting grooves are opened on the side of the storage box near the cabinet door. Adjusting blocks are slidably connected to the inner walls of the two connecting grooves. A movable plate is fixedly connected to one side of the adjusting block. The movable plate is rotatably connected to the cabinet door.

[0021] The effect achieved by the above components is as follows: by setting up storage components, pulling the handle opens the cabinet door, the cabinet door moves along the connecting groove via a moving plate, the adjusting block moves along the side column to slide out of the coating cabinet, making it easy to put in and take out steel or collect waste materials, and the storage box automatically retracts when the cabinet door is closed.

[0022] Preferably, the inner wall of the coating cabinet is fixedly connected to two slide rails, and the inner wall of the slide rails is slidably connected to the side column.

[0023] The effect achieved by the above components is that the side column is slidably connected to the slide rail, which guides and limits the sliding of the storage box, prevents the storage box from tilting during the sliding process, and ensures that the storage box enters and exits the coating cabinet smoothly.

[0024] A method for applying an anti-rust coating to a steel surface includes the following steps:

[0025] S1. Check whether the support on the lower surface of the coating cabinet is stable, whether the power supply to the control panel is on, and whether the coating nozzle is working properly.

[0026] S2. Place the steel body on the bottom plate on the upper surface of the placement plate, and adjust the position of the steel body to align it with the coating nozzle.

[0027] S3. Start the two cylinders on the upper surface of the placement plate. The cylinders push the pull plate to slide along the vertical groove on the inner wall of the connecting plate. The pull plate drives the connecting plate to move. The connecting plate drives the connecting plate to rotate. The connecting plate drives the top plate to descend. The top plate and the bottom plate clamp the steel body from the top and bottom sides. The right-angled trapezoidal rubber pads on the inner side of the top plate and the bottom plate make elastic contact with the surface of the steel body. The pads deform to fill the unevenness of the steel surface and increase the friction.

[0028] S4. Slide the sliding plate. The sliding block on the lower surface of the sliding plate slides along the sliding groove on the upper surface of the fixed plate. The sliding plate drives the servo motor and the toothed column to move, so that the toothed column is engaged in the toothed hole on the inner wall of the connecting column.

[0029] S5. Start the servo motor. The servo motor drives the gear column to rotate. The gear column drives the connecting column and the placement plate to rotate through the tooth hole. The placement plate drives the rotating column to rotate on the vertical plate. The square groove on the upper surface of the placement plate allows the steel body to still be coated after the placement plate rotates.

[0030] S6. Start the coating nozzles on the top wall of the coating cabinet. The coating nozzles spray an anti-rust coating onto the surface of the steel body. The control panel controls the coating parameters.

[0031] S7. During the coating process, the servo motor is repeatedly started as needed to rotate the steel body at multiple angles, so that the anti-rust coating can be evenly covered on the surface of the steel.

[0032] S8. After coating is completed, turn off the coating nozzle and servo motor, start the cylinder in reverse, the cylinder pulls the pull plate to move in the opposite direction, the pull plate drives the connecting plate and the connecting plate to rotate in the opposite direction, the connecting plate drives the top plate to rise, and release the steel body.

[0033] S9. Remove the coated steel body from the placement plate and place it in the storage box for temporary storage.

[0034] S10. When it is necessary to remove residual paint from the inner wall of the coating cabinet, start the drive motor of the inner wall of the coating cabinet. The drive motor drives the screws on the inner walls of the two side plates to rotate. The screws drive the auxiliary plate to slide along the arc surface of the crossbar. The auxiliary plate drives the two columns on the lower surface to move. The columns drive the mounting plate to move. The mounting plate drives the cleaning plate that is engaged with the inner wall of the loading and unloading slot to move. The cleaning plate drives several brushes on the lower surface to move. The brushes clean the inner wall of the coating cabinet and remove residual paint.

[0035] S11. During the cleaning process, the two ends of the spring on the arc surface of the column are fixedly connected to the auxiliary plate and the mounting plate respectively. The elastic force of the spring keeps the brush in elastic contact with the inner wall of the coating cabinet, buffering the collision between the brush and the inner wall.

[0036] S12. After cleaning is complete, turn off the drive motor, remove the cleaning plate from the mounting plate's mounting slot, clean the brush, and then reinsert it into the mounting slot for later use.

[0037] S13. When it is necessary to retrieve the steel or clean up the waste in the storage box, pull the two handles on one side of the cabinet door. The cabinet door will rotate and open around one side of the coating cabinet. The cabinet door will drive the moving plate to rotate. The moving plate will drive the adjusting block to slide along the connecting groove on the side of the storage box near the cabinet door. The adjusting block will drive the storage box to move. The side posts on both sides of the storage box will slide along the slide rail on the inner wall of the coating cabinet. The storage box will slide out of the coating cabinet.

[0038] S14. After taking out or placing steel or cleaning up waste, push the cabinet door to close. The storage box will automatically retract into the coating cabinet, and the side column will slide in the slide rail to ensure that the storage box moves in and out smoothly.

[0039] S15. Turn off the power to the coating cabinet, clean the work surface, and complete the coating operation of the anti-rust coating on the steel surface.

[0040] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0041] 1. In this invention, by setting up a clamping assembly, the cylinder pushes the pull plate to slide along the vertical groove, the pull plate drives the connecting plate and the connecting plate to rotate, the connecting plate drives the top plate to descend, and the top plate and the bottom plate cooperate to clamp the steel body from the upper and lower sides, thereby realizing the rapid clamping and fixing of the steel, preventing the steel from shifting during the coating process, and improving the coating uniformity and accuracy.

[0042] 2. In this invention, by setting up a cleaning component, the screw rotates and drives the auxiliary plate to move along the crossbar. The auxiliary plate drives the column and the mounting plate to move. The mounting plate drives the cleaning plate and the brush to move. The brush cleans the inner wall of the coating cabinet, removes residual paint, and keeps the equipment clean.

[0043] 3. In this invention, by setting up a storage component, pulling the handle opens the cabinet door, and the cabinet door drives the adjusting block to slide along the connecting groove via a moving plate. The adjusting block drives the storage box to slide out of the coating cabinet along the side column, which is convenient for taking out and putting in steel or collecting waste materials. When the cabinet door is closed, the storage box automatically retracts. Attached Figure Description

[0054] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0055] Example 1, such as Figure 1 As shown, the present invention provides a coating device and method for applying an anti-rust coating to a steel surface, including a coating cabinet 1, a steel body 5, and a clamping assembly 6. Several supports 2 are fixedly connected to the lower surface of the coating cabinet 1, a control panel 3 is fixedly connected to one side of the coating cabinet 1, a coating nozzle 4 is installed on the top wall of the inner wall of the coating cabinet 1, the steel body 5 is installed on the inner wall of the coating cabinet 1 by means of the clamping assembly 6, a cleaning assembly 7 is provided on the inner wall of the coating cabinet 1, and a storage assembly 8 is provided on one side of the coating cabinet 1.

[0056] The following section will explain the specific settings and functions of its clamping, cleaning, and storage components.

[0057] like Figure 2 and Figure 4As shown, the clamping assembly 6 includes a vertical plate 601, which is fixedly connected to the inner wall of the coating cabinet 1. A rotating column 602 is rotatably connected to one end of the vertical plate 601. A fixing plate 610 is fixedly connected to the inner wall of the coating cabinet 1. A connecting column 604 is rotatably connected to the side of the fixing plate 610 closest to the vertical plate 601. The ends of the connecting column 604 and the rotating column 602 that are close to each other are fixedly connected to the same placement plate 603. A square groove 609 is formed on the upper surface of the placement plate 603. A square groove 609 is fixedly connected to the upper surface of the placement plate 603. Two base plates 605 are rotatably connected to both sides of the two base plates 605. The same top plate 607 is rotatably connected to the upper surface of the two connecting plates 606. A connecting plate 616 is fixedly connected to one side of one of the connecting plates 606. A vertical groove 617 is opened on the inner wall of the connecting plate 616. Two cylinders 608 are fixedly connected to the upper surface of the placement plate 603. Pull plates 618 are fixedly connected to the output ends of the two cylinders 608. The two pull plates 618 are slidably connected to the inner walls of the two vertical grooves 617 respectively. By setting the clamping assembly 6, the cylinder 608 pushes the pull plate 618 to slide along the vertical groove 617. The pull plate 618 drives the connecting plate 616 and the connecting plate 606 to rotate. The connecting plate 606 drives the top plate 607 to descend. The top plate 607 and the bottom plate 605 cooperate to clamp the steel body 5 from the top and bottom sides, realizing the rapid clamping and fixing of the steel, preventing the steel from shifting during the coating process, and improving the coating uniformity and accuracy. The upper surface of the fixing plate 610 is slidably connected to the sliding plate 611. The upper surface of the sliding plate 611 is fixedly connected to the servo motor 612. The output end of the servo motor 612 is fixedly connected to the toothed column 613. The inner wall of the connecting column 604 is provided with a toothed hole 615. The toothed column 613 is engaged with the toothed hole 615. Servo motor 612 drives gear column 613 to rotate. Gear column 613 drives connecting column 604 and placement plate 603 to rotate through gear hole 615, realizing multi-angle flip coating of steel, so that the anti-rust coating evenly covers the surface of steel and improves the coating effect. Sliding block 620 is fixedly connected to the lower surface of sliding plate 611. Sliding groove 619 is opened on the upper surface of fixed plate 610. The size of sliding groove 619 is adapted to sliding block 620. Sliding block 620 is slidably connected in sliding groove 619, which guides and limits the movement of sliding plate 611, ensuring that gear column 613 accurately engages or disengages from gear hole 615, realizing the switching between flip drive and locking. A gasket 614 is fixedly connected to the side of bottom plate 605 and top plate 607 that are close to each other. The cross-sectional shape of gasket 614 is a right trapezoid and gasket 614 is a rubber gasket. The right-angled trapezoidal rubber pad 614 is fixed to the inner side of the bottom plate 605 and the top plate 607. When the top plate 607 descends to clamp the steel, the pad 614 uses the elastic deformation of the rubber to fill the unevenness of the steel surface, increase the friction to prevent slippage, and avoid damaging the steel surface.

[0058] The overall clamping assembly achieves the following effect: by setting the clamping assembly 6, the cylinder 608 pushes the pull plate 618 to slide along the vertical groove 617, the pull plate 618 drives the connecting plate 616 and the connecting plate 606 to rotate, the connecting plate 606 drives the top plate 607 to descend, and the top plate 607 and the bottom plate 605 cooperate to clamp the steel body 5 from the top and bottom sides, thereby realizing the rapid clamping and fixing of the steel, preventing the steel from shifting during the coating process, and improving the coating uniformity and accuracy.

[0059] like Figure 5 and Figure 6 As shown, the cleaning component 7 includes two side plates 701. The inner walls of the two side plates 701 are rotatably connected to the same screw 702. The arc surface of the screw 702 is threadedly connected to an auxiliary plate 703. The inner wall of the coating cabinet 1 is fixedly connected to a crossbar 704. The arc surface of the crossbar 704 is slidably connected to the auxiliary plate 703. The lower surface of the auxiliary plate 703 is slidably connected to two columns 705. The lower surface of the two columns 705 is fixedly connected to a mounting plate 706. The lower surface of the mounting plate 706 is provided with a loading and unloading groove 711. The inner wall of the loading and unloading groove 711 is engaged with a cleaning plate 708. The lower surface of the cleaning plate 708 is fixedly connected to several brushes 709. By setting up the cleaning component 7, the screw 702 rotates, driving the auxiliary plate 703 to move along the crossbar 704. The auxiliary plate 703 drives the column 705 and the mounting plate 706 to move. The mounting plate 706 drives the cleaning plate 708 and the brush 709 to move. The brush 709 cleans the inner wall of the coating cabinet 1, removing residual paint and keeping the equipment clean. Springs 707 are fitted on the arc surfaces of the two columns 705. The two ends of the springs 707 are fixedly connected to the auxiliary plate 703 and the mounting plate 706, respectively. The spring 707 is fitted on the arc surface of the column 705, and the two ends are fixedly connected to the auxiliary plate 703 and the mounting plate 706, respectively. The elasticity of the spring 707 keeps the brush 709 in elastic contact with the inner wall of the coating cabinet 1, improving the cleaning effect and buffering the collision between the brush 709 and the inner wall. A drive motor 710 is fixedly connected to the inner wall of the coating cabinet 1. The output end of the drive motor 710 is fixedly connected to one end of the screw 702. The drive motor 710 drives the screw 702 to rotate, providing automated power for the movement of the cleaning component 7, thereby achieving automatic cleaning of the inner wall of the coating cabinet 1, which is more labor-saving and efficient than manual cleaning.

[0060] The overall cleaning component achieves the following effect: by setting up the cleaning component 7, the screw 702 rotates and drives the auxiliary plate 703 to move along the crossbar 704. The auxiliary plate 703 drives the column 705 and the mounting plate 706 to move. The mounting plate 706 drives the cleaning plate 708 and the brush 709 to move. The brush 709 cleans the inner wall of the coating cabinet 1, removes residual paint, and keeps the equipment clean.

[0061] like Figure 7 and Figure 8As shown, the storage component 8 includes a cabinet door 81 and a storage box 85. The cabinet door 81 is rotatably connected to one side of the coating cabinet 1. Two handles 82 are fixedly connected to one side of the cabinet door 81. Side posts 83 are fixedly connected to both sides of the storage box 85. The side posts 83 are slidably connected to the inner wall of the coating cabinet 1. Two connecting grooves 86 are opened on the side of the storage box 85 near the cabinet door 81. Adjusting blocks 87 are slidably connected to the inner walls of the two connecting grooves 86. A movable plate 88 is fixedly connected to one side of the adjusting block 87. The movable plate 88 is rotatably connected to the cabinet door 81. By setting up the storage component 8, pulling the handle 82 opens the cabinet door 81. The cabinet door 81, via the moving plate 88, drives the adjusting block 87 to slide along the connecting groove 86. The adjusting block 87 drives the storage box 85 to slide out of the coating cabinet 1 along the side column 83, facilitating the loading and unloading of steel or the collection of waste materials. When the cabinet door 81 is closed, the storage box 85 automatically retracts. Two slide rails 84 are fixedly connected to the inner wall of the coating cabinet 1, and the inner wall of the slide rails 84 is slidably connected to the side column 83. The side column 83 is slidably connected within the slide rails 84, guiding and limiting the sliding of the storage box 85, preventing the storage box 85 from tilting during the sliding process, and ensuring that the storage box 85 smoothly enters and exits the coating cabinet 1.

[0062] The overall effect of the storage component is that by setting up the storage component 8, pulling the handle 82 opens the cabinet door 81. The cabinet door 81 drives the adjusting block 87 to slide along the connecting groove 86 via the moving plate 88. The adjusting block 87 drives the storage box 85 to slide out of the coating cabinet 1 along the side column 83, which is convenient for taking out and putting in steel or collecting waste materials. When the cabinet door 81 is closed, the storage box 85 automatically retracts.

[0063] The overall working principle is as follows: By setting the clamping component 6, when it is necessary to clamp and fix the steel body 5 for rust-proof coating, the steel body 5 is first placed on the bottom plate 605 on the upper surface of the placement plate 603. Then, the two cylinders 608 on the upper surface of the placement plate 603 are activated. The cylinders 608 push the pull plate 618 to slide along the vertical groove 617 on the inner wall of the connecting plate 616. The pull plate 618 drives the connecting plate 616 to move. The connecting plate 616 drives the connecting plate 606 to rotate. The connecting plate 606 drives the top plate 607 to descend. The top plate 607 and the bottom plate 605 cooperate to clamp the steel body 5 from the top and bottom sides. The right-angled trapezoidal rubber pad 614 on the side of the top plate 607 and the bottom plate 605 that is close to each other makes elastic contact with the surface of the steel body 5. The pad 614 deforms to fill the unevenness of the steel surface and increase the friction. At the same time, the sliding plate 611... The sliding block 620 on the lower surface slides along the sliding groove 619 on the upper surface of the fixed plate 610. The sliding plate 611 drives the servo motor 612 and the toothed column 613 to move, so that the toothed column 613 can be inserted into or disengaged from the toothed hole 615 on the inner wall of the connecting column 604. When it is necessary to flip the steel, the servo motor 612 is started. The servo motor 612 drives the toothed column 613 to rotate. The toothed column 613 drives the connecting column 604 and the placement plate 603 to rotate through the toothed hole 615. The placement plate 603 drives the rotating column 602 to rotate on the vertical plate 601. The square groove 609 allows the placement plate to still be coated after rotation, realizing multi-angle flipping coating of the steel. The coating nozzle 4 on the inner wall and top wall of the coating cabinet 1 sprays the anti-rust coating onto the surface of the steel body 5. The control panel 3 controls the coating parameters. The support 2 supports the coating cabinet 1, so that the anti-rust coating evenly covers the surface of the steel and improves the coating effect.

[0064] By setting the cleaning component 7, when it is necessary to remove residual paint from the inner wall of the coating cabinet 1, the drive motor 710 of the inner wall of the coating cabinet 1 is first started. The drive motor 710 drives the screws 702 on the inner wall of the two side plates 701 to rotate. The screws 702 drive the auxiliary plate 703 to slide along the arc surface of the crossbar 704. The auxiliary plate 703 drives the two columns 705 on the lower surface to move. The columns 705 drive the mounting plate 706 to move. The mounting plate 706 drives the cleaning plate 708, which is engaged with the inner wall of the loading and unloading slot 711, to move. The cleaning plate 708 drives several brushes 709 on the lower surface to move. The brushes 709 clean the inner wall of the coating cabinet 1 and remove residual paint. The two ends of the springs 707 on the arc surface of the columns 705 are fixedly connected to the auxiliary plate 703 and the mounting plate 706 respectively. The elasticity of the springs 707 keeps the brushes 709 in elastic contact with the inner wall of the coating cabinet 1, buffering the collision between the brushes 709 and the inner wall and keeping the equipment clean.

[0065] By setting up the storage component 8, when it is necessary to take out or put in steel or collect waste materials, first pull the two handles 82 on one side of the cabinet door 81. The cabinet door 81 rotates and opens around one side of the coating cabinet 1. The cabinet door 81 drives the moving plate 88 to rotate. The moving plate 88 drives the adjusting block 87 to slide along the connecting groove 86 on the side of the storage box 85 near the cabinet door 81. The adjusting block 87 drives the storage box 85 to move. The side columns 83 on both sides of the storage box 85 slide along the slide rail 84 on the inner wall of the coating cabinet 1. The side columns 83 slide in the slide rail 84 to guide and limit. The storage box 85 slides out of the coating cabinet 1. After taking out or putting in steel or collecting waste materials, push the cabinet door 81 to close. The storage box 85 automatically retracts into the coating cabinet 1 to prevent the storage box 85 from tilting during the sliding process and to ensure that the storage box 85 enters and exits the coating cabinet 1 smoothly.

[0066] A method for applying an anti-rust coating to a steel surface includes the following steps:

[0067] S1. Check whether the support 2 on the lower surface of the coating cabinet 1 is stable, whether the power supply of the control panel 3 is connected, and whether the coating nozzle 4 is normal.

[0068] S2. Place the steel body 5 on the base plate 605 on the upper surface of the placement plate 603, and adjust the position of the steel body 5 so that it is aligned with the coating nozzle 4.

[0069] S3. Start the two cylinders 608 on the upper surface of the placement plate 603. The cylinders 608 push the pull plate 618 to slide along the vertical groove 617 on the inner wall of the connecting plate 616. The pull plate 618 drives the connecting plate 616 to move. The connecting plate 616 drives the connecting plate 606 to rotate. The connecting plate 606 drives the top plate 607 to descend. The top plate 607 and the bottom plate 605 clamp the steel body 5 from the upper and lower sides. The right-angled trapezoidal rubber pads 614 on the inner side of the top plate 607 and the bottom plate 605 are in elastic contact with the surface of the steel body 5. The pads 614 deform to fill the unevenness of the steel surface and increase the friction.

[0070] S4. Slide the sliding plate 611. The sliding block 620 on the lower surface of the sliding plate 611 slides along the sliding groove 619 on the upper surface of the fixed plate 610. The sliding plate 611 drives the servo motor 612 and the toothed column 613 to move, so that the toothed column 613 is inserted into the toothed hole 615 on the inner wall of the connecting column 604.

[0071] S5. Start the servo motor 612. The servo motor 612 drives the gear column 613 to rotate. The gear column 613 drives the connecting column 604 and the placement plate 603 to rotate through the tooth hole 615. The placement plate 603 drives the rotating column 602 to rotate on the vertical plate 601. The square groove 609 on the upper surface of the placement plate 603 ensures that the steel body 5 can still be coated after the placement plate rotates.

[0072] S6. Start the coating nozzle 4 on the inner and top walls of the coating cabinet 1. The coating nozzle 4 sprays an anti-rust coating onto the surface of the steel body 5. The control panel 3 controls the coating parameters.

[0073] S7. During the coating process, the servo motor 612 is repeatedly started as needed to rotate the steel body 5 at multiple angles, so that the anti-rust coating can evenly cover the surface of the steel.

[0074] S8. After coating is completed, turn off the coating nozzle 4 and servo motor 612, reverse start cylinder 608, cylinder 608 pulls pull plate 618 to move in the opposite direction, pull plate 618 drives connecting plate 616 and connecting plate 606 to rotate in the opposite direction, connecting plate 606 drives top plate 607 to rise, and release steel body 5.

[0075] S9. Remove the coated steel body 5 from the placement plate 603 and place it in the storage box 85 for temporary storage.

[0076] S10. When it is necessary to remove the residual paint from the inner wall of the coating cabinet 1, start the drive motor 710 on the inner wall of the coating cabinet 1. The drive motor 710 drives the screws 702 on the inner wall of the two side plates 701 to rotate. The screws 702 drive the auxiliary plate 703 to slide along the arc surface of the crossbar 704. The auxiliary plate 703 drives the two columns 705 on the lower surface to move. The columns 705 drive the mounting plate 706 to move. The mounting plate 706 drives the cleaning plate 708 that is engaged with the inner wall of the loading and unloading slot 711 to move. The cleaning plate 708 drives several brushes 709 on the lower surface to move. The brushes 709 clean the inner wall of the coating cabinet 1 to remove the residual paint.

[0077] S11. During the cleaning process, the two ends of the spring 707 on the arc surface of the column 705 are fixedly connected to the auxiliary plate 703 and the mounting plate 706 respectively. The elastic force of the spring 707 keeps the brush 709 in elastic contact with the inner wall of the coating cabinet 1, buffering the collision between the brush 709 and the inner wall.

[0078] S12. After cleaning is completed, turn off the drive motor 710, remove the cleaning plate 708 from the mounting plate 706 under the mounting plate 706, clean the brush 709 and then put it back into the mounting plate 711 for later use.

[0079] S13. When it is necessary to retrieve the steel in the storage box 85 or clean up the waste, pull the two handles 82 on one side of the cabinet door 81. The cabinet door 81 rotates and opens around one side of the coating cabinet 1. The cabinet door 81 drives the moving plate 88 to rotate. The moving plate 88 drives the adjusting block 87 to slide along the connecting groove 86 on the side of the storage box 85 near the cabinet door 81. The adjusting block 87 drives the storage box 85 to move. The side columns 83 on both sides of the storage box 85 slide along the slide rail 84 on the inner wall of the coating cabinet 1. The storage box 85 slides out of the coating cabinet 1.

[0080] S14. After taking out or putting in steel or cleaning up waste, push the cabinet door 81 to close. The storage box 85 will automatically retract into the coating cabinet 1. The side column 83 will slide in the slide rail 84 to ensure that the storage box 85 moves in and out smoothly.

[0081] S15. Turn off the power to coating cabinet 1, clean the work surface, and complete the coating operation of the anti-rust coating on the steel surface.
