Description

Technical Field

[0001] This application relates to the field of steel processing technology, and in particular to a steel surface coating equipment. Background Technology

[0002] In the steel processing industry, in order to improve the corrosion resistance and aesthetics of steel, it is usually necessary to coat the surface of the steel.

[0003] Currently, for small-batch steel processing, most coating operations rely on manual hand-held spray guns. In practice, the efficiency of manual hand-held spray guns is relatively low. Because it requires manual movement of the spray gun and control of the spray uniformity, the operator expends considerable physical and mental energy, resulting in limited spraying speed and making it difficult to meet the needs of large-scale production.

[0004] Secondly, manual spraying often struggles to guarantee uniformity. The operator's spraying skills and experience directly impact coating quality, and significant differences can exist between different operators. Furthermore, prolonged continuous work can lead to operator fatigue, further affecting coating uniformity and quality.

[0005] To address the aforementioned issues, a steel surface coating equipment is now designed. Utility Model Content

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] This application provides a steel surface coating equipment that can solve the problem in related technologies where most coating operations for small-batch steel processing rely on manual hand-held spray guns, resulting in relatively low work efficiency.

[0046] Please see Figures 1-3 A steel surface coating device includes: a support frame 1, and a conveyor belt 2 disposed on one side of the support frame; a tray 3, which is slidably disposed on the conveyor belt 2 and used to place the steel to be coated; a spraying mechanism 4, which includes a liquid supply section 41 and a spraying section 42 disposed on the support frame 1, wherein the liquid supply section 41 is used to supply spraying liquid to the spraying section 42, and the spraying section 42 is used to spray the steel; and a driving member 5, which is disposed on the support frame 1 and used to drive the spraying section 42 to move along the length of the conveyor belt 2.

[0047] The spray unit 42 includes a mounting bracket 421 connected to the drive component 5. The mounting bracket 421 has a plurality of spray pipes 422, and the bottom of each spray pipe 422 is provided with a plurality of spray heads 423. The spray unit 42 also includes a transmission pipe 424 for supplying spray liquid to the plurality of spray pipes 422.

[0048] Conveyor belt 2 is used to carry and transport the steel to be coated. Pallet 3 is slidably mounted on conveyor belt 2 to hold the steel to be coated, ensuring that the steel remains stable during transport.

[0049] The liquid supply section 41 is used to store the spray liquid, and the transmission pipe 424 is used to send the liquid inside the liquid supply section 41 into the spray pipe 422.

[0050] The mounting bracket 421 is connected to the drive component 5 for installing and fixing the spray pipe 422. The bottom of the spray pipe 422 is provided with several spray heads 423 for evenly spraying the spray liquid onto the steel surface.

[0051] The driving component 5 drives the mounting block 55 and the spraying part 42 to move along the length of the conveyor belt 2, thereby achieving continuous spraying of the steel surface.

[0052] By utilizing the conveyor belt 2, pallet 3, spraying mechanism 4, and drive unit 5 in combination, rapid and continuous spraying of steel surfaces is achieved, greatly improving spraying efficiency. Compared to manual handheld spraying, it can complete the coating of large areas of steel in a short time, reducing labor intensity and increasing efficiency.

[0053] By employing multiple spray pipes 422 and spray heads 423, the spray liquid can be evenly sprayed onto the steel surface, ensuring the uniformity and consistency of the coating thickness. At the same time, it can significantly reduce labor and time costs.

[0054] Specifically, the liquid supply unit 41 in this embodiment includes a tank 411 and a pump 412 mounted on the support 1. The inlet of the pump 412 is connected to the tank 411, and the outlet of the pump 412 is provided with a hose 413, which is connected to the transmission pipeline 424.

[0055] Tank 411, serving as a storage container for the spraying liquid, is mounted on bracket 1. Tank 411 is equipped with a liquid supply port and a delivery pipe to ensure that the spraying liquid is always kept within a safe operating range.

[0056] The inlet of pump body 412 is connected to the bottom of tank 411 via a pipe, ensuring that pump body 412 can smoothly draw in spray liquid. Pump body 412 uses a high-performance hydraulic pump or air pump with sufficient pressure and flow to meet the spraying requirements of spray section 42.

[0057] When the pump body 412 is started, its internal mechanical structure begins to operate, drawing the spray liquid from the tank 411 and discharging it through the outlet. A flexible hose 413 is provided at the outlet, which can be easily connected to the transmission pipeline 424.

[0058] In one embodiment, such as Figure 4 and Figure 5As shown, the driving component 5 includes: a support platform 51 mounted on the bracket 1; a lead screw 52 rotatably mounted at the bottom of the support platform 51; two guide rods 53 oppositely mounted at the bottom of the support platform 51; a transmission sleeve 54 threadedly connected to the lead screw 52; a mounting block 55 mounted on the outside of the transmission sleeve 54, the mounting block 55 slidingly engaging with the guide rods 53; and a drive motor 56 mounted on the support platform 51, the output shaft of the drive motor 56 being connected to one end of the lead screw 52. The transmission sleeve 54 has a thread adapted to the lead screw 52 inside, and the mounting block 55 has mounting holes adapted to the guide rods 53.

[0059] The support platform 51 provides a stable support platform for the entire drive unit 5. The lead screw 52 is the main component for transmission. The surface of the lead screw 52 is machined with helical threads for threaded connection with the transmission sleeve 54. The guide rod 53 is used to limit the rotational movement of the transmission sleeve 54, ensuring that it can only move along the axial direction of the lead screw 52.

[0060] The transmission sleeve 54 has a thread inside that is compatible with the lead screw 52. Through the threaded connection with the lead screw 52, ​​it can move along the axial direction of the lead screw 52.

[0061] Mounting block 55 is used to mount and fix the spray unit 42. Mounting block 55 has mounting holes that are adapted to guide rod 53, so that mounting block 55 can slide on guide rod 53 while maintaining a stable direction of movement.

[0062] The output shaft of the drive motor 56 is connected to one end of the lead screw 52 and is used to drive the lead screw 52 to rotate.

[0063] When the drive motor 56 starts, its output shaft drives the lead screw 52 to rotate. Since the transmission sleeve 54 is threadedly connected to the lead screw 52 and its rotation is restricted by the guide rod 53, the transmission sleeve 54 will move along the axial direction of the lead screw 52. The movement of the transmission sleeve 54 drives the mounting block 55 and the spray section 42 to move together, realizing the reciprocating motion of the spray section 42 along the length direction of the conveyor belt 2.

[0064] By controlling the speed and direction of the drive motor 56, the moving speed and direction of the spray unit 42 can be adjusted to meet the coating needs of steel of different specifications and materials.

[0065] In one embodiment, the mounting frame 421 is U-shaped and is connected to one end of the mounting block 55; a plurality of spray pipes 422 are arranged between the mounting frames 421 and distributed along the width of the conveyor belt 2; the plurality of spray pipes 422 are located directly above the conveyor belt 2.

[0066] The U-shaped mounting bracket 421 has its opening facing the conveyor belt 2, and one side is firmly connected to one end of the mounting block 55. This connection method allows the spray unit 42 to move with the mounting block 55, realizing reciprocating motion along the length of the conveyor belt 2.

[0067] The spray pipes 422 are arranged between the U-shaped mounting brackets 421 and are evenly distributed along the width of the conveyor belt 2, ensuring that the spray liquid can be evenly sprayed on all parts of the steel surface and avoiding the problem of uneven coating.

[0068] The spray pipe 422 is located directly above the conveyor belt 2. This layout allows the spray liquid to be sprayed directly onto the steel surface, reducing the loss and waste of the spray liquid in the air. At the same time, it also ensures that the steel is continuously covered by the spray liquid during the conveying process, improving coating efficiency and quality.

[0069] As a preferred embodiment, such as Figure 3 As shown, the transmission pipeline 424 includes a main pipeline 4241 mounted on the mounting bracket 421. Multiple valves 4242 are provided at the bottom of the main pipeline 4241, and the other end of each valve 4242 is connected to a corresponding spray pipe 422. One end of the main pipeline 4241 is connected to the flexible hose 413.

[0070] The main pipe 4241 serves as the primary channel for transporting the spraying liquid. One end of the main pipe 4241 is connected to the hose 413 to ensure that the spraying liquid can be stably transported from the supply unit 41 to the spraying unit 42.

[0071] The number of valves 4242 corresponds to the number of spray pipes 422. The other end of each valve 4242 is connected to the corresponding spray pipe 422 to control the flow direction and flow rate of the spray liquid. By adjusting the opening of the valve 4242, the spray volume of each spray pipe 422 can be flexibly adjusted to ensure a uniform coating effect on the steel surface.

[0072] Furthermore, the valve 4242 allows for flexible control of the spray liquid's flow direction and flow rate. During the coating process, the spray volume of each spray pipe 422 can be adjusted by regulating the opening of the valve 4242 according to the steel's material, specifications, and coating requirements, achieving a personalized coating effect.

[0073] like Figure 6 As shown, the conveyor belt 2 in this embodiment includes a plurality of rectangularly distributed support columns 21, with a side plate 22 abutting the top of the support column 21 on the same side, and a plurality of transmission rollers 23 rotatably arranged between two side plates 22.

[0074] The conveyor belt 2 also includes an electric push rod disposed inside the support column 21. The piston rod of the electric push rod is fixedly connected to the bottom of the side plate 22, and the electric push rod is used to drive the side plate 22 to rise and fall. The top of the support column 21 has a cavity for accommodating the electric push rod.

[0075] The support pillar 21 serves as the supporting structure for the conveyor belt 2. Multiple support pillars 21 are arranged in a rectangular pattern to ensure the stability and load-bearing capacity of the conveyor belt.

[0076] A steel conveying channel is formed between the two side plates 22. The side plates 22 not only serve as supports and guides, but also achieve lifting and lowering functions through the electric push rod at their bottom.

[0077] The drive roller 23 is the power source for steel conveying. By pushing the pallet 3 to move, the drive roller 23 is driven to rotate, enabling continuous and stable conveying of steel.

[0078] The lifting function of the electric push rod allows the height of the conveyor belt 2 to be flexibly adjusted to meet the needs of conveying steel of different heights, and also provides convenience during equipment maintenance or adjustment.

[0079] In another embodiment, in order to realize the automatic operation of the conveyor belt 2, the conveyor belt 2 also includes a chain plate with transmission on multiple transmission rods, and a drive motor and reducer set on the side plate 22. This is prior art and will not be described in detail here.

[0080] like Figure 7 As shown, this embodiment also includes a guide mechanism 6, which includes two mounting plates 61 disposed opposite to each other on the support platform 51, a guide rod 62 disposed between the two mounting plates 61, and a guide block 63 sleeved on the guide rod 62;

[0081] The support platform 51 has a sliding hole, and the guide block 63 passes through the sliding hole and is connected to the mounting block 55.

[0082] The guiding mechanism 6, through the cooperation of the guide rod 62 and the guide block 63, provides a clear movement path for the mounting block 55 and the spray unit 42 connected to it, ensuring the stability and accuracy of the spray unit 42 during movement and avoiding deviation from the predetermined path.

[0083] like Figure 6 As shown, in this embodiment, the tray 3 is also provided with a plurality of support rods 31, and a filter screen 32 is arranged above the plurality of support rods 31.

[0084] Multiple support rods 31 are evenly distributed inside the tray, providing stable support for the filter screen 32 placed on the tray. The main function of the filter screen 32 is to support the steel and filter the spray liquid dripping after spraying, which is then collected through the tray 3.
