Description

Technical Field

[0001] This utility model relates to the field of aluminum-magnesium alloy sheet processing technology, and in particular to a spraying equipment for processing aluminum-magnesium alloy thin sheets. Background Technology

[0002] Aluminum-magnesium alloy sheet is an alloy material composed of aluminum, magnesium, and other metallic elements. Its main component is aluminum, with small amounts of magnesium or other metallic materials added to enhance its hardness. Aluminum-magnesium alloy sheet is characterized by its high strength, light weight, low density, good heat dissipation, and strong compressive strength, and is widely used in various fields. During the processing of aluminum-magnesium alloy sheet, surface treatment using spraying equipment is necessary to improve its wear resistance, corrosion resistance, and aesthetics.

[0003] In existing aluminum-magnesium alloy sheet processing and spraying technologies, the number of spray heads is usually fixed. This design has significant shortcomings when dealing with sheets of varying widths. When the sheet is wide, a fixed number of spray heads cannot cover the entire surface, resulting in incomplete coating and affecting processing quality. Conversely, when the sheet is narrow, excess spray heads lead to paint waste and increased production costs. Furthermore, after spraying, a certain amount of paint often remains in the pipes. This residual paint tends to dry and harden gradually in the pipes and spray heads after the equipment is shut down, causing blockages. This blockage not only affects the normal operation of the equipment but also increases maintenance costs and downtime. In severe cases, it may even require replacing the pipes and spray heads, causing significant inconvenience to production. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a spraying equipment for processing aluminum-magnesium alloy thin plates, including a frame 1, a conveying mechanism 11 between the inner walls of both sides of the frame 1, a spraying box 2 on the top wall of the frame 1, a mounting plate 3 fixedly connected between the inner walls of both sides of the spraying box 2, a plurality of spray nozzles 31 mounted on the lower side wall of the mounting plate 3, pipe clamps 21 fixedly connected to both sides of the upper inner wall of the spraying box 2, a diversion pipe 4 between two pipe clamps 21, and a plurality of connecting cavities 32 opened on the mounting plate 3, the diversion pipe 4 connecting to the connecting cavities 31. The cavities 32 are connected by connecting pipes 41. Each connecting pipe 41 is equipped with a solenoid valve 42. The solenoid valve 42 can control the opening and closing of the corresponding connecting pipe 41. The corresponding nozzle 31 can be flexibly opened or closed according to the width of the board, ensuring that the spraying range matches the width of the board. This avoids incomplete spraying, reduces paint waste, and improves paint utilization. The upper outer wall of the spray box 2 is equipped with a liquid supply mechanism 5, and the lower outer wall of the frame 1 is equipped with a positioning mechanism 6.

[0024] Specifically, such as Figure 3As shown, a spraying device for processing aluminum-magnesium alloy thin plates includes a liquid supply mechanism 5 comprising a liquid storage tank 51, a paint tank 52, a pump 53, an electric reversing valve 54, a liquid supply pipe 55, a material supply pipe 56, a conveying pipe 57, and a transfer pipe 58. The liquid storage tank 51, the paint tank 52, and the pump 53 are fixedly connected to the upper outer wall of the spraying box 2. An electric reversing valve 54 is installed on the upper outer wall of the spraying box 2, located between the liquid storage tank 51 and the paint tank 52. The first port of the electric reversing valve 54 is connected to the liquid storage tank 51 via the liquid supply pipe 55, and the second port is connected to the paint tank 52 via the material supply pipe 56. The input end of the pump 53 is connected to the third port of the electric reversing valve 54 via the conveying pipe 57. The output end of the pump 53 is connected to the distribution pipe 4 via the adapter pipe 58. During the spraying process, the electric reversing valve 54 controls the connection between the supply pipe 56 and the delivery pipe 57, so that the pump 53 can extract the paint from the paint tank 52 and deliver the paint to the distribution pipe 4 via the adapter pipe 58. After the spraying is completed, the electric reversing valve 54 switches the pipeline, so that the liquid supply pipe 55 is connected to the delivery pipe 57. At this time, the pump 53 can extract the rinsing liquid from the storage tank 51 and deliver the rinsing liquid to each distribution pipe 4 via the adapter pipe 58. Then, it enters the connecting cavity 32 through the connecting pipe 41 and is sprayed out through the nozzle 31 to rinse the pipeline and nozzle 31, avoiding the blockage problem caused by paint residue.

[0025] Specifically, such as Figure 1 and Figure 4As shown, a spraying device for processing aluminum-magnesium alloy thin plates includes a straightening mechanism 6 comprising a U-shaped frame 61, limiting rods 62, moving blocks 63, a bidirectional screw 64, a rotating wheel 65, a driving rod 66, an L-shaped plate 67, and rollers 68. A U-shaped frame 61 is fixedly connected to the front of the lower side wall of the frame 1. Two limiting rods 62 are fixedly connected between the inner walls of the two sides of the U-shaped frame 61. Two symmetrically distributed moving blocks 63 are slidably sleeved between the two limiting rods 62. A bidirectional screw 64 is rotatably arranged between the inner walls of the two sides of the U-shaped frame 61. The moving blocks 63 are threaded onto the bidirectional screw 64. One end of the bidirectional screw 64 passes through one side wall of the U-shaped frame 61 and is fixedly connected to a rotating wheel 65. A driving rod 66 is fixedly connected to the upper side wall of the moving blocks 63. An L-shaped plate 67 is fixedly connected to the upper end of the driving rod 67. The upper inner wall of the L-shaped plate 67 is provided with several rollers 68. Rotating the rollers 65 can drive the bidirectional screw 64 to rotate. When the bidirectional screw 64 rotates, it can cause the two moving blocks 63 to move closer or further apart under the guidance of the limiting rod 62. Under the drive of the driving rod 66, the two L-shaped plates 67 will also move closer or further apart, which serves to control the distance between the two L-shaped plates 67. After determining the distance between the two L-shaped plates 67 according to the width of the plate, the conveying mechanism 11 can ensure that the plate is in the middle position of the conveying roller when conveying the plate, avoiding the plate being placed on the conveying roller and the plate being misaligned during the conveying process, which would result in incomplete spraying. During the conveying process, the setting of the rollers 68 will not obstruct the movement of the plate, ensuring that the plate can be conveyed normally.

[0026] Specifically, such as Figure 4 As shown, a spraying device for processing aluminum-magnesium alloy thin plates has an L-shaped connecting rod 69 fixedly connected to the rear side wall of the moving block 63. The other end of the L-shaped connecting rod 69 is fixed together with the L-shaped plate 67. When the moving block 63 moves, the L-shaped connecting rod 69 moves together to ensure the stability of the L-shaped plate 67.

[0027] Specifically, such as Figure 1 As shown, a spraying device for processing aluminum-magnesium alloy thin plates has a controller 7 installed on one outer wall of the spraying box 2.

[0028] Specifically, such as Figure 1 As shown, a spraying device for processing aluminum-magnesium alloy thin plates includes a conveying mechanism 11, a pump 53, an electric reversing valve 54, and a solenoid valve 42, all of which are electrically connected to a controller 7. The control method of this device is controlled by the controller 7. The control circuit of the controller 7 can be implemented by simple programming by those skilled in the art, and is a mature existing technology, which will not be described in detail here.

[0029] It should be noted that this utility model is a spraying equipment for processing aluminum-magnesium alloy thin plates. In use, the number of spray nozzles 31 to be opened is first determined according to the width of the plate. Then, the corresponding solenoid valve 42 is closed via the controller 7. After the solenoid valve 42 is closed, the paint cannot enter the connecting pipe 41 through the diverter pipe 4, and thus the corresponding spray nozzles 31 will not spray paint. Then, the rotating wheel 65 drives the bidirectional screw 64 to rotate. When the bidirectional screw 64 rotates, it can cause the two moving blocks 63 to move closer or further apart under the guidance of the limit rod 62. Under the drive of the driving rod 66, the two L-shaped plates 67 will also move closer or further apart, thus controlling the distance between the two L-shaped plates 67. After determining the distance between the two L-shaped plates 67 according to the width of the plate, the conveying mechanism 11 can ensure that the plate is in the middle position of the conveying roller when conveying the plate, avoiding misalignment of the plate on the conveying roller and during the conveying process, which would result in incomplete spraying. During the conveying process, the roller... The wheel 68 does not obstruct the movement of the sheet material, ensuring normal conveying. The spraying program is started by the controller 7. During spraying, the electric reversing valve 54 controls the connection between the supply pipe 56 and the conveying pipe 57, so that the pump 53 can draw out the paint from the paint tank 52 and use the transfer pipe 58 to transport the paint to the diversion pipe 4. Then, it enters the connecting cavity 32 through the connecting pipe 41 and is sprayed onto the surface of the sheet material through the nozzle 31. After the spraying operation is completed, the flushing program is started by the controller 7. At this time, the controller 7 controls all the solenoid valves 42 to open and controls the electric reversing valve 54 to switch the pipeline, so that the liquid supply pipe 55 is connected to the conveying pipe 57. At this time, the pump 53 can draw out the flushing liquid from the storage tank 51 and use the transfer pipe 58 to transport the flushing liquid to each diversion pipe 4. Then, it enters the connecting cavity 32 through the connecting pipe 41 and is sprayed out through the nozzle 31 to flush the pipeline and nozzle 31, avoiding clogging caused by paint residue.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
