Description

Technical Field

[0001] The present application relates to the technical field of spraying equipment, and in particular to a steel spraying equipment. Background Art

[0002] Steel is widely used in various engineering construction projects, such as buildings, bridges and mechanical equipment. In the manufacturing process, in order to provide protection, beautification and enhance the wear resistance of steel, it is usually necessary to spray the steel surface. This process not only improves the quality and service life of steel, but also effectively reduces the economic losses caused by corrosion and other reasons, and improves the overall quality and safety of engineering projects.

[0003] In the prior art, the spraying operation for steel is usually carried out in a spraying room in a workshop. Specifically, the steel is placed on a workbench in the spraying room and sprayed by a spray gun in the spraying room. The spraying room provides a relatively closed space, which helps to reduce the impact of pollutants generated during the spraying process on the external environment, and also protects operators from harmful substances.

[0004] However, existing spraying equipment has obvious shortcomings when handling long strips of steel. Since this type of steel is long and has a certain weight, operators face great difficulties in moving it in or out of the spray room, which not only increases the labor intensity but also may lead to operational errors. More importantly, during the transfer or spraying process of steel, operators are often required to frequently enter the spray room for adjustment and inspection. Long-term exposure to harmful environments will have adverse effects on the physical and mental health of operators. Therefore, how to simplify the transfer operation of steel and reduce the number of times operators enter the spray room has become an urgent problem to be solved. Summary of the invention

[0005] In order to simplify the transfer operation of steel and reduce the number of times operators enter the spraying room, the present application provides a steel spraying equipment.

[0006] The steel spraying equipment provided in this application adopts the following technical solution: A steel spraying equipment comprises a spraying chamber, a spraying module, a moving module and a flipping module, wherein one side of the spraying chamber is provided with an inlet and outlet connected to the outside, and the spraying module is arranged in the spraying chamber to spray the surface of the steel; the moving module comprises a moving seat, a support plate and a positioning bar, the moving seat is slidably installed in the spraying chamber, and can be moved into or out of the spraying chamber through the inlet and outlet, the support plate is arranged on the moving seat, the positioning bar is arranged on the upper surface of the support plate, and the top wall of the positioning bar is provided with a positioning groove for steel to be embedded; the flipping module is arranged on the moving seat to drive the steel to flip.

[0007] By adopting the above technical solution, through the setting of the moving seat and the flip module, when spraying the steel, the moving seat is moved out through the entrance and exit of the spray room, and then the steel is placed on the positioning bar of the support plate. The positioning groove of the positioning bar can position the steel. After the placement is completed, the steel is driven by the moving seat to move into the spray room for spraying, thereby improving the convenience of operation of the steel in and out of the spray room. In addition, when the steel is moved into the spray room for spraying, the setting of the flip module enables the steel to be flipped, so that the spray module can spray different surfaces of the steel, reduce the spraying dead angle, and thus reduce the possibility of the operator needing to enter the spray room during the spraying process, which is beneficial to the physical and mental health of the operator.

[0008] Optionally, the spray module includes a spray seat, a spray gun and a translation member, the spray seat is slidably installed in the spray chamber and is located on the top of the movable seat, the spray gun is arranged on the bottom wall of the spray seat to spray the surface of the steel; the translation member is arranged in the spray chamber, and the translation member is used to drive the spray seat to slide back and forth along the length direction of the steel.

[0009] By adopting the above technical solution, the spraying seat, spray gun and translation member are arranged, so that the spray gun can reciprocate along the length direction of the steel in the spraying room, thereby achieving uniform and comprehensive spraying on the surface of the steel. This not only improves the spraying efficiency, but also ensures the spraying quality and improves the automation level of the entire spraying process.

[0010] Optionally, the flipping module includes a fixed frame, a movable frame, a moving component and a flipping component, the fixed frame is fixedly mounted on the moving seat, the movable frame is slidably mounted on the moving seat and can move closer to or farther away from the fixed frame; the fixed frame and the movable frame are both rotatably mounted with rotating disks, and the surface of each rotating disk has an embedding portion for embedding into steel; the moving component is arranged between the moving seat and the movable frame, and when the moving seat is moved into the spraying room, the moving component forces the movable frame to move toward the fixed frame, and forces the embedding portion of the rotating disk of the fixed frame and the embedding portion of the rotating disk of the movable frame to be respectively embedded in the two ends of the steel; the flipping component is arranged on the rotating disk to drive the rotating disk to rotate around its own central axis.

[0011] By adopting the above technical solution, when the movable seat moves into the spray chamber, the movable assembly forces the movable frame to move toward the fixed frame. As the movable frame moves, the embedded part of the rotating disk of the movable frame can be embedded in one end of the steel material, and the steel material is pushed to move toward the fixed frame synchronously, so that the embedded part of the rotating disk of the fixed frame can be embedded in the other end of the steel material, thereby docking the two ends of the steel material, so that the steel material and the rotating disk are docked with each other. After the embedded part of the rotating disk of the fixed frame and the embedded part of the rotating disk of the movable frame are respectively embedded in the two ends of the steel material, the spray gun can be driven to slide along the length direction of the steel material to spray the surface of the steel material; after one of the surfaces of the steel material is sprayed, the rotating disk is driven to rotate by the flip assembly, which can drive the steel material to flip around the central axis of the rotating disk, so that the spray module can fully spray different surfaces of the steel material, reduce spraying dead angles, and improve spraying efficiency and quality.

[0012] Optionally, a mounting strip is provided on the top wall of the movable seat, the mounting strip is provided with a sliding groove, a sliding block is provided on the side wall of the movable frame, the sliding block is slidably mounted in the sliding groove, and the movable frame is slidably mounted on the mounting strip of the movable seat through the sliding block; the movable assembly includes a first gear, a first rack and a second rack, the first gear is rotatably mounted on the mounting strip, the first rack is mounted on the sliding block, and the first rack and the first gear are meshed for transmission; the second rack is mounted on the inner wall of the spray chamber, and when the movable seat moves into the spray chamber, the second rack and the first gear are meshed for transmission, and the sliding block is forced to move relative to the mounting strip toward the side close to the fixed frame, so that the embedded part of the rotating disk of the fixed frame and the embedded part of the rotating disk of the movable frame are respectively embedded in the two ends of the steel.

[0013] By adopting the above technical solution, when the moving seat drives the movable frame to move into the spraying room, the first gear can be meshed with the second rack. As the moving seat continues to move in, the second rack drives the first gear to rotate, thereby driving the sliding block to move relative to the mounting bar toward the side close to the fixed frame under the action of the first rack. When the moving seat moves into the spraying room, the movable frame can be displaced toward the fixed frame, so that the embedded part of the rotating disk of the fixed frame and the embedded part of the rotating disk of the movable frame can be respectively embedded in the two ends of the steel, thereby achieving a firm clamping of the steel and improving the operational convenience of docking between the steel and the rotating disk.

[0014] Optionally, a lifting groove is provided on the top wall of the movable seat, and the support plate is slidably installed in the lifting groove so as to be able to be lifted and lowered; a lifting screw is rotatably installed on the side wall of the movable seat, and a lifting bar is provided on the bottom wall of the support plate, and the lifting screw is passed through the lifting bar and is threadedly connected to the lifting bar; a second gear is coaxially provided on the circumferential wall of one end of the lifting screw, and a third rack is provided on the inner wall of the spray chamber, and both ends of the third rack are extended along the length direction of the positioning bar, and when the embedded parts of the rotating disk of the fixed frame and the embedded parts of the rotating disk of the movable frame are respectively embedded in the two ends of the steel, and the movable seat continues to move toward the spray chamber, the second gear and the third rack are meshed and force the support plate to sink to separate from the steel.

[0015] By adopting the above technical solution, when the embedded parts of the rotating disk of the fixed frame and the embedded parts of the rotating disk of the movable frame are respectively embedded in the two ends of the steel material, the movable seat continues to move into the spray chamber, and the meshing action between the second gear and the third rack forces the support plate to sink, thereby realizing the separation of the support plate from the steel material. This allows the positioning strip on the support plate to avoid the steel material, and then the rotating disk can drive the steel material to flip, reducing the interference between the positioning strip and the steel material when the steel material flips.

[0016] Optionally, the movable frame is rotatably installed with a rotating shaft, and the rotating shaft and the rotating disk are meshed for transmission; the flip assembly includes a driving rod, a driving disk, a rocker arm, a return spring and a pushing member, one end of the driving rod is connected to the side wall of the spray seat, the driving disk is coaxially connected to the outer peripheral wall of the rotating shaft, one end of the rocker arm is hinged to the movable frame, and the return spring is installed between the rocker arm and the movable frame, when the spray seat moves to the inlet and outlet of the spray chamber, the driving rod pushes the rocker arm to swing; the pushing member is arranged on the rocker arm, and when the rocker arm swings, the pushing member drives the driving disk to rotate.

[0017] By adopting the above technical solution, when the spray seat drives the spray gun to move to the entrance and exit of the spray room, the driving rod pushes the swing arm to swing, and the swing of the swing arm prompts the pusher to drive the driving disk to rotate, thereby driving the rotating disk to rotate a certain angle; the spray seat slides back and forth along the length direction of the steel, and can push the swing arm intermittently, so that the steel flips an angle every time the spray seat moves a stroke, so that the spray gun can spray different surfaces of the steel, greatly improving the spraying efficiency. In addition, this design enables the flipping module to automatically complete the flipping action of the steel without the need for an external power source, thereby improving the automation of the equipment, reducing manual intervention, and ensuring the continuity and stability of the spraying operation. At the same time, the mechanism has a simple structure, high reliability, and reduces the maintenance cost of the equipment.

[0018] Optionally, a plurality of push grooves are provided on the outer peripheral wall of the driving disk, and the plurality of push grooves are arranged at intervals around the central axis of the driving disk; the pushing member includes a pushing block and a torsion spring, one end of the pushing block is hinged to the rocker arm, and the torsion spring is installed at the hinge of the pushing block and the rocker arm, and the torsion spring forces the free end of the pushing block to be embedded in the pushing groove of the driving disk; when the rocker arm swings, the pushing block pushes the driving disk through the inner wall of the pushing groove, so that the driving disk rotates around the central axis of the rotating shaft.

[0019] By adopting the above technical solution, the torsion spring forces the free end of the push block to be embedded in the push groove of the driving disk. When the driving rod pushes the swing arm to swing, the swing arm can drive the driving disk to rotate through the push block, thereby driving the rotating disk to rotate a certain angle to achieve the "flipping" of the steel. After the steel flips a certain angle, the spray seat is driven to move toward the side away from the inlet and outlet, and the swing arm is reset under the action of the reset spring, so that when the spray seat continues to move to the inlet and outlet, the driving rod can continue to push the swing arm to swing, realizing the intermittent rotation of the rotating disk, and then realizing the intermittent "flipping" of the steel.

[0020] Optionally, the number of rotating disks of the fixed frame and the number of rotating disks of the movable frame are correspondingly arranged; each rotating disk of the movable frame is coaxially arranged with a first bevel gear, and the peripheral wall of the rotating shaft is coaxially arranged with a plurality of second bevel gears, the plurality of second bevel gears are arranged correspondingly to the plurality of first bevel gears, and each of the second bevel gears is meshed with the corresponding first bevel gear for transmission; the rotation directions of two adjacent rotating disks in the movable frame are set to be opposite.

[0021] By adopting the above technical solution, multiple sets of rotating disks are set up to connect multiple steel materials, so that the overall structure can spray multiple steel materials at one time, thereby improving the spraying efficiency; the setting of the first bevel gear and the second bevel gear enables meshing transmission between the rotating shaft and the rotating disk; in addition, when the rotating disk drives the steel material to rotate, the force balance changes during the rotation of the steel material, causing the rotating disk to have a tendency to rotate sharply, thereby forming a steering force on the rotating shaft, and setting the rotation directions of two adjacent rotating disks in the movable frame to be opposite, thereby eliminating the steering force from the steel material, making the rotation operation of the rotating shaft smoother, and improving the rotation stability of the rotating shaft.

[0022] Optionally, a limit plate is coaxially provided on the circumferential wall of the rotating shaft, and a plurality of anti-rotation grooves are opened on the circumferential wall of the limit plate, and the plurality of anti-rotation grooves are arranged at intervals around the central axis of the limit plate; a limit block is slidably installed on the movable frame, and a limit spring is provided between the limit block and the movable frame, and the limit spring forces the limit block to embed into the anti-rotation groove of the limit plate to limit the free rotation of the rotating shaft; the driving rod is provided with an unlocking rod, and when the spray seat moves to the entrance and exit of the spray chamber, the unlocking rod forces the limit block to disengage from the anti-rotation groove.

[0023] By adopting the above technical solution, the setting of the limit plate and the limit block is used to limit the rotation axis, reducing the possibility that the friction between the push block and the drive plate causes the drive plate to reverse with the push block when the swing arm is reset under the action of the reset spring, thereby reducing the possibility of the rotation axis rotating freely and improving the stability of the overall structure. When the spray seat moves to the entrance and exit of the spray room, the unlocking rod can force the limit block to disengage from the anti-rotation groove, thereby releasing the lock on the rotation axis, allowing the flip assembly to work normally and realize the precise flipping of the steel.

[0024] Optionally, an air supply pipe for blowing hot air is installed in the spraying room, the peripheral wall of the air supply pipe is connected with a docking pipe, and the rotating disk of the fixed frame is provided with a docking hole. When the movable seat is completely moved into the spraying room, the docking pipe is inserted into the steel through the docking hole.

[0025] By adopting the above technical solution, when the movable seat is completely moved into the spraying room, the docking pipe of the air supply pipe penetrates into the steel through the docking hole on the rotating disk of the fixed frame, so that hot air can be blown into the steel, accelerating the drying speed of the paint, reducing the spraying time, and improving production efficiency.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the moving seat and the flip module, when spraying the steel, the moving seat is moved out through the entrance and exit of the spray room, and then the steel is placed on the positioning bar of the support plate. The positioning groove of the positioning bar can position the steel. After the placement is completed, the moving seat drives the steel into the spray room for spraying, which improves the convenience of steel entering and exiting the spray room. In addition, when the steel is moved into the spray room for spraying, the setting of the flip module enables the steel to be flipped, so that the spray module can spray different surfaces of the steel, reduce the spraying dead angle, and thus reduce the possibility of the operator needing to enter the spray room during the spraying process, which is beneficial to the physical and mental health of the operator; 2. Through the setting of the flipping assembly, when the spray seat drives the spray gun to move to the entrance and exit of the spray room, the driving rod pushes the rocker arm to swing, and the swing of the rocker arm prompts the pusher to drive the driving disk to rotate, thereby driving the rotating disk to rotate a certain angle; the spray seat slides back and forth along the length direction of the steel, and can push the rocker arm intermittently, so that the steel flips an angle every time the spray seat moves a stroke, so that the spray gun can spray different surfaces of the steel, greatly improving the spraying efficiency. In addition, this design enables the flipping module to automatically complete the flipping of the steel without the need for an external power source, thereby improving the automation of the equipment, reducing manual intervention, and ensuring the continuity and stability of the spraying operation. At the same time, the mechanism has a simple structure, high reliability, and reduces the maintenance cost of the equipment; 3. The setting of the limit plate and the limit block is used to limit the rotation axis, reducing the possibility that the friction between the push block and the drive plate causes the drive plate to reverse with the push block when the swing arm is reset under the action of the reset spring, thereby reducing the possibility of the rotation axis rotating freely and improving the stability of the overall structure. When the spray seat moves to the entrance and exit of the spray room, the unlocking rod can force the limit block to disengage from the anti-rotation groove, thereby releasing the lock on the rotation axis, allowing the flip assembly to work normally and realize the precise flipping of the steel.

It should be noted that when the second gear 315 and the third rack 12 just start to engage, the embedded portion 431 of the rotating disk 43 of the fixed frame 41 is embedded in one end of the steel, and there is still a gap between the rotating disk 43 of the fixed frame 41 and the end surface of the steel (that is, the embedded portion 431 of the rotating disk 43 of the fixed frame 41 is not fully inserted into the steel), and this gap provides sliding space for the engagement of the second gear 315 and the third rack 12; when the support plate 32 sinks and detaches from the steel, the embedded portion 431 of the rotating disk 43 of the fixed frame 41 is fully inserted into the steel.

[0042] The implementation principle of the embodiment 1 of the present application is as follows: the setting of the movable seat 31 improves the convenience of operation of steel entering and exiting the spraying room 1. Before placing the steel, the movable frame 42 can be moved to the side of the mounting bar 311 away from the fixed frame 41 to expand the distance between the movable frame 42 and the fixed frame 41, so that the steel can be placed on the positioning bar 33 of the support plate 32.

[0043] Then, the movable seat 31 is driven to move into the spraying room 1. During the displacement of the movable seat 31, the movable frame 42 can move toward the fixed frame 41 and push the steel on the positioning bar 33, so that the embedded part 431 of the rotating disk 43 of the fixed frame 41 and the embedded part 431 of the rotating disk 43 of the movable frame 42 are respectively embedded in the two ends of the steel.

[0044] Continue to drive the movable seat 31 to move into the spraying room 1, and the support plate 32 can sink to avoid the steel, so that the flip assembly 6 can drive the steel to flip around the central axis of the rotating disk 43, so that the spray gun 22 can comprehensively spray different surfaces of the steel, reduce blind spots in spraying, improve spraying efficiency and quality, and reduce the possibility of operators needing to enter the spraying room 1 during the spraying process, which is beneficial to the physical and mental health of the operators. Example 2

[0045] The embodiment of the present application discloses a steel spraying device.

[0046] Reference Figure 8 , Fig. 9 The difference between the steel spraying equipment disclosed in the embodiment of the present application and the embodiment 1 is that: In this embodiment, the flip assembly 6 is arranged on the movable frame 42, and the movable frame 42 is rotatably mounted with a rotating shaft 7 away from the side wall of the fixed frame 41, and the two ends of the rotating shaft 7 are extended along the width direction of the first slide rail 15. Each rotating disk 43 of the movable frame 42 is coaxially fixed with a first bevel gear 432, and a plurality of second bevel gears 71 are coaxially fixed to the peripheral wall of the rotating shaft 7. The plurality of second bevel gears 71 are correspondingly arranged with the plurality of first bevel gears 432, and each second bevel gear 71 is meshed with the corresponding first bevel gear 432 for transmission, so that the rotating shaft 7 and the rotating disk 43 are meshed for transmission. It should be noted that when the rotating shaft 7 rotates, the rotation directions of the two adjacent rotating disks 43 in the movable frame 42 are set to be opposite.

[0047] Reference Fig. 9 , Fig.10In this embodiment, the flip assembly 6 includes a driving rod 61, a driving disk 62, a swing rod 63, a reset spring 64 and a pusher. One end of the driving rod 61 is fixedly connected to the side wall of the spraying seat 21 near the inlet and outlet 11, and the length direction of the driving rod 61 is consistent with the length direction of the first slide rail 15. One end of the rotating shaft 7 passes through the sliding groove 312 of the mounting bar 311 and is coaxially fixed to the driving disk 62. The side wall of the sliding block 421 away from the movable frame 42 is fixedly installed with the mounting frame 44. In this embodiment, the first rack 52 is fixedly installed on the top wall of the mounting frame 44, and the first rack 52 is connected to the sliding block 421 through the mounting frame 44. The lower end of the rocker arm 63 is hinged to the mounting frame 44 of the movable frame 42. One end of the return spring 64 is connected to the side wall of the rocker arm 63, and the other end is connected to the mounting frame 44 of the movable frame 42. The return spring 64 normally causes the upper end of the rocker arm 63 to be tilted toward the side close to the fixed frame 41. When the spray seat 21 moves to the inlet and outlet 11 of the spray chamber 1, the driving rod 61 pushes the upper end of the rocker arm 63 to swing toward the side away from the fixed frame 41.

[0048] Reference Fig. 9 , Fig.10 The pusher is arranged on the swing rod 63. When the upper end of the swing rod 63 swings toward the side away from the fixed frame 41, the pusher drives the driving disk 62 to rotate. The outer peripheral wall of the driving disk 62 is provided with a plurality of push grooves 621, and the plurality of push grooves 621 are arranged at intervals around the central axis of the driving disk 62. The pusher includes a push block 65 and a torsion spring. One end of the push block 65 is hinged to the swing rod 63. For the convenience of description, the end of the push block 65 away from the swing rod 63 is defined as the free end of the push block 65. The torsion spring (not shown in the figure) is installed at the hinge of the push block 65 and the swing rod 63. The torsion spring forces the free end of the push block 65 to be embedded in the push groove 621 of the driving disk 62. When the swing rod 63 swings, the push block 65 pushes the driving disk 62 through the inner wall of the push groove 621, so that the driving disk 62 rotates around the central axis of the rotating shaft 7.

[0049] The implementation principle of Example 2 of the present application is as follows: when the spray seat 21 drives the spray gun 22 to move to the inlet and outlet 11 of the spray chamber 1, the driving rod 61 pushes the rocker arm 63 to swing, and the swing of the rocker arm 63 prompts the pushing member to drive the driving disk 62 to rotate, thereby driving the rotating disk 43 to rotate a certain angle, thereby realizing the "flipping" of the steel; the spray seat 21 slides back and forth along the length direction of the steel, and can intermittently push the rocker arm 63, so that the steel completes a "flip" every time the spray seat 21 moves a stroke, realizing intermittent "flipping" of the steel, and then the spray gun 22 can spray different surfaces of the steel, greatly improving the spraying efficiency.

[0050] In addition, the design enables the turning module 4 to automatically turn the steel without the need for an external power source, thereby improving the automation of the equipment, reducing manual intervention, and ensuring the continuity and stability of the spraying operation. At the same time, the mechanism has a simple structure, high reliability, and reduces the maintenance cost of the equipment. Example 3

[0051] The embodiment of the present application discloses a steel spraying device.

[0052] Reference Fig.11 The difference between the steel spraying equipment disclosed in the embodiment of the present application and the embodiment 2 is that: In this embodiment, a limiting plate 72 is coaxially fixed to the peripheral wall of the rotating shaft 7. The limiting plate 72 is located between the driving plate 62 and the mounting bar 311. A plurality of anti-rotation grooves 721 are provided on the peripheral wall of the limiting plate 72. The plurality of anti-rotation grooves 721 are arranged at intervals around the central axis of the limiting plate 72. It should be noted that the number of anti-rotation grooves 721 corresponds to the number of push grooves 621. The mounting frame 44 of the movable frame 42 is slidably mounted with a connecting bar 424. The side wall of the connecting bar 424 is fixedly mounted with a limiting block 422. The limiting block 422 is slidably mounted on the mounting frame 44 of the movable frame 42 through the connecting bar 424 and can be lifted and lowered. A limit spring 423 is installed between the connecting strip 424 and the mounting frame 44. One end of the limit spring 423 is fixedly connected to the connecting strip 424, and the other end is fixedly connected to the mounting frame 44. The limit spring 423 forces the limit block 422 to sink and embed into the anti-rotation groove 721 of the limit plate 72 to limit the free rotation of the rotating shaft 7.

[0053] Reference Fig.11 In this embodiment, the unlocking rod 611 is fixedly mounted on the peripheral wall of the driving rod 61. The unlocking rod 611 includes a straight section 612 and an inclined section 613. The length direction of the straight section 612 is consistent with the length direction of the driving rod 61. One end of the straight section 612 is fixedly connected to the driving rod 61. The height of the inclined section 613 gradually decreases from the end close to the straight section 612 to the end away from the straight section 612. The connecting bar 424 is provided with a guide groove 425 for the unlocking rod 611 to pass through. When the spray seat 21 moves to the inlet and outlet 11 of the spray chamber 1, the inclined section 613 of the unlocking rod 611 passes through the guide groove 425 and forces the connecting bar 424 to lift, so that the limit block 422 is separated from the anti-rotation groove 721 of the limit plate 72.

[0054] The implementation principle of Example 3 of the present application is as follows: the setting of the limit plate 72 and the limit block 422 is used to limit the rotation shaft 7, reducing the possibility that the friction between the push block 65 and the drive plate 62 causes the drive plate 62 to reverse following the push block 65 when the swing arm 63 is reset under the action of the tension spring, thereby reducing the possibility of the rotation shaft 7 rotating freely and improving the stability of the overall structure. When the spray seat 21 moves to the inlet and outlet 11 of the spray chamber 1, the inclined section 613 of the unlocking rod 611 can force the limit block 422 to lift up to disengage from the anti-rotation groove 721, thereby releasing the lock on the rotation shaft 7, so that the flip assembly 6 can work normally and realize the precise flipping of the steel. Example 4

[0055] The embodiment of the present application discloses a steel spraying device.

[0056] Reference Fig.12 The difference between the steel spraying equipment disclosed in the embodiment of the present application and the embodiment 2 is that: An air supply pipe 13 for blowing hot air is installed in the spraying room 1. The air supply pipe 13 is fixedly installed on the inner wall of the spraying room 1 in the form of a clamp. The length direction of the air supply pipe 13 is consistent with the width direction of the first slide rail 15. One end of the air supply pipe 13 passes through the spraying room 1 and is used to connect the hot air supply equipment (not shown in the figure). A plurality of docking pipes 131 are fixedly installed on the peripheral wall of the air supply pipe 13. The plurality of docking pipes 131 are arranged corresponding to the number of rotating disks 43 of the fixed frame 41. A docking hole 433 is provided on the surface of each rotating disk 43 of the fixed frame 41. When the movable seat 31 is completely moved into the spraying room 1, the docking pipe 131 penetrates into the steel through the docking hole 433. The rotating disk 43 of the fixed frame 41 is also provided with a vent 434, and the vent 434 is used for the hot air in the steel to flow out.

[0057] The implementation principle of Example 4 of the present application is as follows: when the movable seat 31 is completely moved into the spray chamber 1, the docking pipe 131 of the air supply pipe 13 penetrates into the interior of the steel through the docking hole 433 on the rotating disk 43 of the fixed frame 41, so that the air supply pipe 13 and the interior of the steel are connected. When the steel surface is sprayed, hot air is blown into the steel through the air supply pipe 13, and the conveying pipe 14 is used to supply air into the spray chamber 1, so as to heat the steel inside and outside, accelerate the drying speed of the coating, and improve production efficiency. In addition, the air supply pipe 13 can also be used to preheat the steel before spraying, which can improve the spraying quality to a certain extent.
