Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, and more specifically, it relates to a fixing device for metal sheet spray painting. Background Technology

[0002] In the processing of metal sheets, the painting process is an important step. Its purpose is to provide a protective layer for the metal sheets, increasing their corrosion resistance, UV resistance, wear resistance, and aesthetics. It is widely used in building decoration, furniture manufacturing, automobile manufacturing, home appliances, and electronic product casings.

[0003] Traditional metal sheet surface painting usually involves workers using handheld spray guns to spray metal sheets placed on a workbench. However, due to the limitations of manual operation, larger metal sheets often require segmented spraying, which reduces the overall painting efficiency. Furthermore, after spraying one side of the metal sheet, workers need to flip it over to spray the other side. This operation is not only inconvenient but also time-consuming, especially since the coating needs time to dry or cure before it can be flipped. This further increases the total painting time and affects the painting efficiency of metal sheets. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixing device for metal sheet painting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fixing device for metal sheet spray painting includes a worktable with two mounting plates fixed on the upper surface of the worktable. The mounting plates are connected to positioning components for fixing the metal sheet, and the positioning components are movably connected to the edge of the metal sheet.

A cylinder is fixed under the worktable, and the output end of the cylinder passes through the table plate of the worktable and is connected to the lifting seat. The output end of the cylinder is movably connected to the table plate of the worktable.

[0006] Further configured, the positioning component includes a fixed plate, a telescopic rod, an adjusting screw, and a clamping roller. The fixed plate corresponds to the edge of the metal plate, and the two ends of the telescopic rod are respectively connected to the mounting plate and the fixed plate. The mounting plate has a threaded hole that is threadedly connected to the adjusting screw. The adjusting screw passes through the threaded hole and is rotatably connected to the fixed plate. The clamping roller is rotatably connected to the fixed plate and abuts against the edge of the metal plate. The clamping roller rolls on the edge of the metal plate.

[0007] A further configuration is provided, wherein the fixed plate has a receiving groove that cooperates with the pressing roller, and the two ends of the pressing roller are connected to shafts, which are rotatably connected to the inner wall of the receiving groove.

[0014] Reference Figures 1 to 3 The embodiments of this utility model will be further described below.

[0015] A fixing device for metal sheet painting includes a workbench 1. Two mounting plates 2 are fixed on the upper surface of the workbench 1. The mounting plates 2 are provided with positioning components 100 for fixing the metal sheet 101. The positioning component 100 includes a fixing plate 5, a telescopic rod 6, an adjusting screw 7, and a clamping roller 8. The fixing plate 5 corresponds to the edge of the metal sheet 101, and the two ends of the telescopic rod 6 are respectively connected to the mounting plate 2 and the fixing plate 5. The mounting plate 2 has a threaded hole 9 for threaded connection with the adjusting screw 7, and the adjusting screw 7 passes through the threaded hole 9. The adjusting screw 7 is rotatably connected to the fixed plate 5 via a bearing. The pressing roller 8 is rotatably connected to the fixed plate 5 and abuts against the edge of the metal plate 101. The pressing roller 8 rolls on the edge of the metal plate 101. A lifting seat 3 for placing the metal plate 101 is provided between the two mounting plates 2. A cylinder 4 is fixed under the worktable 1. The output end of the cylinder 4 passes through the table plate of the worktable 1 and is connected to the lifting seat 3. The output end of the cylinder 4 is movably connected to the table plate of the worktable 1. The cylinder 4 is controlled by a controller.

[0016] Working principle: A large metal sheet 101 to be painted is placed on the lifting seat 3 of the workbench 1. The positioning parts 100 on the two mounting plates 2 fix the metal sheet 101. Specifically, rotating the adjusting screw 7 moves the fixing plate 5 closer to the edge of the metal sheet 101. Continuing to rotate the adjusting screw 7 causes the clamping roller 8 on the fixing plate 5 to abut against the edge of the metal sheet 101, thereby fixing the metal sheet 101 on the lifting seat 3. The extension rod 6 is designed to prevent the fixing plate 5 from rotating along with the clamping roller 8 when the adjusting screw 7 is rotated, thus fixing the edge of the metal sheet 101. At the same time, when the adjusting screw 7 is rotated to move the fixing plate 5, the extension rod 6 extends and retracts with the movement of the fixing plate 5 without affecting the movement of the fixing plate 5.

[0017] The cylinder 4 drives the lifting seat 3 to rise, thereby raising the metal plate 101 so that its bottom aligns with the worker's painting height. During the height adjustment of the metal plate 101, the clamping roller 8 rolls along the edge of the metal plate 101, and the clamping rollers 8 on the two mounting plates 2 abut against the edge of the metal plate 101. This ensures that the metal plate 101 rises smoothly and stably with the lifting seat 3, maintaining its fixation during the raising process. The worker then adjusts the bottom of the metal plate 101. The painting process begins. The cylinder 4 works to slowly lower the metal sheet 101 via the lifting seat 3. As the clamping roller 8 rolls along and contacts the edge of the metal sheet 101, and the friction between the metal sheet 101 and the clamping roller 8 is less than the weight of the metal sheet 101, the metal sheet 101 descends slowly and steadily with the lifting seat 3. This allows the workers to continuously paint the metal sheet 101 from bottom to top, enabling the painting of large metal sheets to be completed in one go without the need for segmented painting.

[0018] After completing the painting operation on one side of the metal sheet 101, the worker moves to the other side of the metal sheet 101 and repeats the above steps to complete the double-sided painting operation of the large-sized metal sheet 101. This avoids the need to flip the metal sheet 101, preventing the problem of difficulty in flipping large-sized metal sheets 101, making the operation convenient. At the same time, it avoids the problem of the coating on one side of the metal sheet 101 needing to cure before flipping it to paint the other side, saving time. Ultimately, it enables continuous painting of large-sized metal sheets 101, avoiding the impact of segmented painting on the overall painting efficiency. After completing the painting of one side of the metal sheet 101, the worker does not need to flip the metal sheet 101, nor does he / she need to wait for the coating on one side of the metal sheet 101 to cure before flipping it to paint the other side. He / she can directly move to the other side of the metal sheet 101 to paint the other side, making the operation convenient, time-saving, and improving the painting efficiency of the metal sheet 101.

[0019] The fixed plate 5 has a receiving groove 10 that cooperates with the pressing roller 8. The two ends of the pressing roller 8 are connected to shafts 81. The shafts 81 are rotatably connected to the inner wall of the receiving groove 10 through bearings, so as to realize the rotatable connection between the pressing roller 8 and the fixed plate 5, which facilitates the pressing roller 8 to roll along the edge of the metal plate 101.

[0020] The workbench 1 has a through hole 11. The output end of the cylinder 4 passes through the through hole 11 and is movably connected to the through hole 11. The output end of the cylinder 4 is movably connected to the workbench 1 through the through hole 11, which also facilitates the connection between the output end of the cylinder 4 and the lifting seat 3 through the workbench 1.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
