Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a continuous painting device for steel structural parts. Background Art

[0002] Steel structures are structures made of steel materials. There are many types of steel structures and they are also widely used. Since each steel structure can be connected by welds, bolts or rivets, and the strength after connection is high and not easy to deform, and because of its own light weight, steel structures are widely used in the field of construction engineering.

[0003] Since steel structures are mostly used for structural frames or decorative exterior panels, they are exposed to the air for a long time after installation. Usually, the surface of the steel structures is sprayed with paint, mainly to protect them from corrosion and increase durability. When general spray painting equipment is used to paint steel structures, most of them can only paint one side of the steel structures, resulting in uneven spraying of the entire steel structure, exposing part of the surface of the steel structure to the air, causing oxidation reactions and generating rust spots, which affects the appearance and internal structure of the steel structure and shortens the service life of the steel structure.

[0004] Therefore, it is necessary to develop a continuous painting device for steel structural parts to solve the above technical problems. Summary of the Invention

[0005] In order to overcome the shortcomings of general paint spraying devices that can only paint one side of steel structures when painting them, resulting in uneven spraying of the entire steel structure, exposing part of the surface of the steel structure to the air, causing oxidation reactions and generating rust spots, which affects the appearance and internal structure of the steel structure and shortens the service life of the steel structure, the utility model provides a continuous paint spraying device for steel structures.

[0006] The technical implementation plan of the utility model is: a continuous painting device for steel structures, including a support seat, a connecting frame, a liquid storage tank, a connecting pipe I, a spray module I, a connecting pipe II, a spray module II, a damping rod, a transmission roller, a support frame, a drive motor and a transmission assembly. A connecting frame is installed above the support seat, and two liquid storage tanks are arranged above the connecting frame. The two liquid storage tanks are connected to the connecting pipe I and the connecting pipe II on the sides away from each other, and the liquid storage tanks are connected and communicated with the connecting pipe I and the connecting pipe II respectively, the other end of the connecting pipe I is connected and communicated with the spray module I, and the other end of the connecting pipe II is connected and communicated with the spray module II. Two damping rods are fixedly connected between the liquid storage tank located at the rear side and the support seat, and the spray module I and the spray module II are both slidably connected to the two damping rods. Multiple transmission rollers are arranged on both sides of the support seat, and support frames are installed on both sides of the support seat. A drive motor is arranged on the support frame, and the multiple transmission rollers are driven by the transmission assembly. The output shafts of the two drive motors are respectively connected to one of the transmission rollers on both sides.

[0007] Furthermore, it also includes a protective shell, a pressure plate, an adjusting rod, a guide rod, an electric slide rail, an electric slider and a limit plate. Protective shells are provided on both sides of the support seat, and the adjusting rod is threadedly connected to the protective shell. The adjusting rod is located in the protective shell and a pressure plate is rotatably provided on one end. Two guide rods are provided on the pressure plate, and the guide rods slide on the protective shell. An electric slide rail is installed on the side of the connecting frame close to the spray module I, and two electric sliders are slidably provided on the electric slide rail. Limit plates are fixed on both sides of the electric slider, and the limit plates slide on the transmission roller.

[0008] Furthermore, it also includes a support shell, a dual-axis motor, a screw and a connecting plate. The support shell is installed on the side of the support seat away from the damping rod. The dual-axis motor is arranged in the support shell. The two output shafts of the dual-axis motor are connected to the screw through a coupling. A connecting plate is provided on the common side of the spray module I and the spray module II, and the connecting plate is threadedly connected to the two screws respectively.

[0009] Furthermore, it also includes an observation panel, and an observation panel is provided on both sides of the liquid storage tank.

[0010] Furthermore, a splash guard is included, and the output ports of the spray module I and the spray module II are both provided with a splash guard.

[0011] Furthermore, it also includes a wiping block, and the wiping block is installed on the side of the support base that is close to each other.

[0012] Compared with the prior art, the utility model has the following advantages: 1. The steel structure is evacuated through the transmission assembly, and the wiping block removes impurities on the surface of the steel structure. Then the spray module I and the spray module II spray the surface of the steel structure at the same time, so that the surface of the steel structure is evenly painted.

[0013] 2. When the steel structure is transmitted through the transmission roller, the adjusting rod is turned to limit the passing steel structure, thereby limiting the steel structure to avoid dislocation of the steel structure during transmission, resulting in uneven painting of the steel structure.

[0014] 3.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: A continuous painting device for steel structure parts, see Figure 1-Figure 3 As shown, it includes a support base 1, a connecting frame 2, a liquid storage tank 3, a connecting pipe I5, a spray module I6, a connecting pipe II7, a spray module II8, a damping rod 10, a transmission roller 11, a support frame 12, a drive motor 13 and a transmission assembly 14. A connecting frame 2 is installed above the support base 1 by bolt connection. Two front and rear liquid storage tanks 3 are arranged above the connecting frame 2. The two liquid storage tanks 3 are connected to the connecting pipe I5 and the connecting pipe II7 on the side away from each other, and the liquid storage tanks 3 are connected and communicated with the connecting pipe I5 and the connecting pipe II7 respectively. The other end of the connecting pipe I5 is connected and communicated with the spray module I6, and the other end of the connecting pipe II7 is connected and communicated with the spray module II8. The output of the spray module I6 is connected to the spray module II8 A splash guard 9 is provided on the opening, which can prevent paint from spreading when spraying the steel plate. Two damping rods 10 are fixedly connected between the liquid storage tank 3 and the support seat 1 at the rear side. The spray module I6 and the spray module II8 are slidingly connected to the two damping rods 10. A plurality of transmission rollers 11 are provided on both sides of the support seat 1. A support frame 12 is installed on both sides of the support seat 1 by bolt connection. A drive motor 13 is provided on the support frame 12. The plurality of transmission rollers 11 are driven by a transmission assembly 14. The output shafts of the two drive motors 13 are respectively connected to one of the transmission rollers 11 on both sides. A wiping block 26 is installed on the side of the support seat 1 close to each other, and the transmission roller 11 drives the steel structure to contact the wiping block 26.

[0024] When it is necessary to spray paint the steel structure, the staff starts the two drive motors 13, so that the drive motor 13 drives the transmission roller 11 to rotate. When the transmission roller 11 rotates, the transmission assembly 14 drives multiple transmission rollers 11 to rotate. Then the staff places the steel structure to be painted on the rolling transmission roller 11. The transmission roller 11 drives the steel structure to slide. When the steel structure slides, it passes through the wiping block 26 to wipe one side of the steel structure, so that impurities on the surface of the steel structure are removed. Then the spray module I6 and the spray module Block II8 draws the metal protective paint in the liquid storage tank 3, so that the metal protective paint flows along the connecting pipe I5 and the connecting pipe II7 into the spray module I6 and the spray module II8. Then the spray module I6 and the spray module II8 spray the surface of the steel structure at the same time, so that the surface of the steel structure is evenly painted. Then the steel structure is rolled out by the transmission roller 11, so as to achieve the effect of continuous and uniform painting on the surface of the steel structure, making the surface of the steel structure beautiful while slowing down the oxidation reaction of the steel structure, so that the service life of the steel structure is increased.

[0025] Example 2: Based on Example 1, refer to Figure 2-Figure 4 As shown, it also includes a protective shell 15, a pressure plate 16, an adjusting rod 17, a guide rod 18, an electric slide rail 19, an electric slider 20 and a limit plate 21. Protective shells 15 are provided on the left and right sides of the support seat 1. The adjusting rod 17 is threadedly connected to the protective shell 15. The lower end of the adjusting rod 17 is rotatably provided with a pressure plate 16. Two guide rods 18 are provided on the pressure plate 16. The guide rod 18 slides on the protective shell 15. An electric slide rail 19 is installed on the side of the connecting frame 2 close to the spray module I6. Two electric sliders 20 are slidably provided on the electric slide rail 19. The limit plates 21 are fixed on both sides of the electric slider 20, and the limit plates 21 slide on the transmission roller 11.

[0026] When the steel structure is transmitted through the transmission roller 11, the staff controls the two electric sliders 20 to drive the limit plate 21 to slide inward along the electric slide rail 19 at the same time, so that the steel structure can be aligned during transmission. Then the staff turns the adjustment rod 17 to slide the pressure plate 16 downward to limit the passing steel structure. During the transmission process, the steel structure is forced by the pressure plate 16 to limit the steel structure, thereby avoiding dislocation of the steel structure during transmission, resulting in uneven painting of the steel structure.

[0027] See Figure 5 and Figure 6As shown, it also includes a support shell 22, a dual-axis motor 23, a screw rod 24 and a connecting plate 25. The support shell 22 is installed on the front side of the support base 1 by means of bolt connection. The dual-axis motor 23 is installed in the support shell 22 by means of bolt connection. The two output shafts of the dual-axis motor 23 are connected to the screw rod 24 through a coupling. The common side of the spray module I6 and the spray module II8 is provided with a connecting plate 25, and the connecting plate 25 is threadedly connected to the two screw rods 24 respectively.

[0028] When it is necessary to paint the steel structure, the staff controls the dual-axis motor 23 to drive the two screw rods 24 to rotate simultaneously. The rotation of the two screw rods 24 causes the spray module I6 and the spray module II8 to slide up or down at the same time, and adjusts the positions of the spray module I6 and the spray module II8 so that when the spray module I6 and the spray module II8 paint the steel structure, the spray distance can be adjusted according to the size of the steel structure, avoiding the metal protective paint from spreading too far due to the spray distance being too far, resulting in a thin and uneven coating and reduced adhesion.

[0029] An observation panel 4 is also included, and an observation panel 4 is provided on both sides of the liquid storage tank 3 .
