Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel sheet spraying technology, specifically to a device for controlling the uniformity of coating on the surface of cold-rolled steel sheets. Background Technology

[0002] To prevent rust from appearing on the surface of cold-rolled steel sheets, it is necessary to spray an anti-rust coating onto the steel sheets. However, it was found that the spraying effect was poor when the spraying equipment was in use. After the spraying was completed, the thickness of the coating was uneven. The different coating thicknesses in different areas would lead to different anti-rust effects, resulting in unsatisfactory anti-rust effects on the main body of the steel sheet.

[0003] Therefore, it is necessary to invent a device for controlling the uniformity of coating on the surface of cold-rolled steel sheets. Summary of the Invention

[0004] Therefore, this utility model provides a device for controlling the uniformity of coating on the surface of cold-rolled steel sheets to solve the problems in the background art.

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] See attached document Figure 1 - Appendix Figure 8 This utility model provides a device for controlling the uniformity of coating on the surface of cold-rolled steel sheets, comprising:

[0033] U-shaped frame 4 is set on top of steel plate body 3. Inside U-shaped frame 4 is shell 5. The bottom of shell 5 is open. A rotating shaft 6 is embedded in shell 5. Gears 7 are fixedly sleeved on both the front and rear ends of rotating shaft 6. One side of each gear 7 is provided with a toothed plate 8 that meshes with it. The two toothed plates 8 are fixedly connected to the inner walls of the front and rear sides of U-shaped frame 4 respectively.

[0034] A rotating plate 9 is fixedly connected to one side of a rotating shaft 6. Multiple pipes 10 are fixedly embedded on the rotating plate 9. Each pipe 10 has a nozzle 11 fixedly connected to its bottom end. Each pipe 10 is equipped with a safety valve 12.

[0035] Three electric push rods 13 are provided. All three electric push rods 13 are fixedly embedded in the top of the U-shaped frame 4, and the bottom ends of the three electric push rods 13 are fixedly connected to the top of the housing 5.

[0036] A feeding assembly for delivering paint to multiple nozzles 11;

[0037] Two rotating rods 14 are fixedly connected to the rotating shaft 6. The inner walls of the front and rear sides of the housing 5 are fixedly connected to the stop rods 15, and the two stop rods 15 are in contact with the two rotating rods 14 respectively.

[0038] In this embodiment, the electric push rod 13 moves the housing 5 downward, which in turn moves the rotating shaft 6, the rotating plate 9, and multiple nozzles 11 downward. Then, under the action of the gear 7 and the toothed plate 8, the nozzles 11 will rotate around the rotating shaft 6 as the axis of rotation when they move downward, so that the nozzles 11 are always vertically downward. In this way, the nozzles 11 are perpendicular to the surface of the steel plate body 3 and will always be perpendicular without any angular deviation. This ensures the quality of the spraying.

[0039] To achieve the purpose of conveying coatings, the device adopts the following technical solution: The feeding component includes a pressure pump 16, which is fixedly connected to the top of the U-shaped frame 4. A second pipe 17 is fixedly connected inside the housing 5. A first hose 18 is fixedly connected between the second pipe 17 and the pressure pump 16. A second hose 19 is fixedly connected to the liquid inlet of the pressure pump 16. A third hose 20 is fixedly connected between the second pipe 17 and multiple first pipes 10. The first hose 18 passes through one side of the housing 5 and is fixedly connected thereto. Two support plates 21 are fixedly connected to one side of the U-shaped frame 4. Both support plates 21 are fixedly connected to the bottom of the pressure pump 16.

[0040] In order to achieve the purpose of stable movement of the housing 5, the device adopts the following technical solution: two limiting rods 22 are fixedly connected to the top of the housing 5. Both limiting rods 22 pass through the top of the U-shaped frame 4 and slide in contact with it. The limiting rods 22 can make the housing 5 move stably.

[0041] In order to achieve the purpose of lateral movement of the housing 5, the device adopts the following technical solution: the bottom of the housing 5 is provided with a frame 1, the top of the frame 1 is fixedly connected with a base plate 2, the top of the base plate 2 is provided with a steel plate body 3, the front and rear sides of the U-shaped frame 4 are provided with electric slide rails 23, the two electric slide rails 23 are provided with sliders 24, the two sliders 24 are fixedly connected to the front and rear sides of the U-shaped frame 4 respectively, the two ends of the two electric slide rails 23 are fixedly connected with upright plates 25, and the four upright plates 25 are fixedly connected to the bottom and top.

[0042] In order to reduce wear, the device adopts the following technical solution: the rotating shaft 6 is connected to the housing 5 through a bearing, which can reduce wear.

[0043] The usage process of this utility model is as follows: When it is necessary to perform anti-rust spraying on the steel plate body 3, the steel plate is placed on the base plate 2. Then, by controlling the three electric push rods 13, the housing 5 and the components on the housing 5 can be moved downward. This allows multiple nozzles 11 to approach the steel plate body 3. During the downward movement, the two gears 7 will move on the toothed plate 8, which will cause the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 will drive the rotating plate 9 and multiple nozzles 11 to rotate. The rotation of the rotating shaft 6 can also cause the two rotating rods 14 to rotate. When the rotating rods 14 rotate to contact the stop rod 15, the outlet of multiple nozzles 11 is vertically downward. That is, the nozzles 11 are perpendicular to the surface of the steel plate body 3. At the same time, the distance between the nozzles 11 and the steel plate body 3 is relatively close. In addition, the nozzles 11 are perpendicular to the steel plate body 3, and the angle will not be deviated. This ensures the quality of the spraying, so that the paint is evenly covered on the surface of the steel plate body 3, thereby ensuring the anti-rust effect.

[0044] During spraying, the end of hose 2 19 is placed in the container storing paint, and then the pressure pump 16 is controlled to work. Then, under the action of hose 2 19, hose 1 18, pipe 2 17 and multiple hoses 3 20, the paint can enter multiple pipes 1 10, and then enter multiple nozzles 11 and be sprayed out. At the same time, the two electric slide rails 23 are controlled to work to make the two sliders 24 move laterally, thereby making the U-shaped frame 4, housing 5, nozzles 11 and components on housing 5 move laterally. In this way, spraying without dead angles can be achieved.

[0045] In addition, a safety valve 12 is designed on each pipe 10, and the opening pressure of each safety valve 12 is set in the same way, so that each nozzle 11 can be sprayed with paint synchronously during spraying.

[0046] After the spraying is completed, the electric push rod 13 is controlled to move the housing 5 and the components on the housing 5 upward to reset. Since the gear 7 meshes with the toothed plate 8, when it moves upward, the rotating shaft 6 can drive the rotating rod 14, multiple pipes 10 and multiple nozzles 11 to rotate, so that the bottom of the multiple nozzles 11 is tilted upward, thus avoiding the dripping of residual paint in the nozzles 11.

[0047] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
