Description

Technical Field

[0001] This utility model relates to the field of metal plate production technology, and in particular to a spraying device for metal plate production. Background Technology

[0002] Metal surface painting is a method to protect metals from oxidation and corrosion. Corrosion, which occurs around us, refers to the damage, performance degradation, or deterioration of various materials under environmental influences (a combination of chemical, electrochemical, and physical factors). Metal surface painting is a crucial means of protecting metals from corrosion. A well-applied paint coating remains continuous, intact, and well-bonded, acting as a barrier to inhibit the intrusion of corrosive media.

[0003] In traditional metal sheet coating processes, the common method involves suspending the metal sheet using hooks, and then having a worker directly spray the sheet with a handheld spray gun. During the coating process, the worker also needs to manually rotate the suspended metal sheet to ensure that all sides are coated; however, this method has many drawbacks. From an efficiency perspective, manual operation is not only slow but also makes it difficult to guarantee the continuity and stability of the coating, resulting in low overall production efficiency and failing to meet the needs of large-scale production. From an environmental impact perspective, during the coating process, a large amount of paint is dispersed into the air in the form of mist. These paint particles not only pollute the air quality in the workshop and endanger the health of workers, but may also adhere to the surfaces of workshop equipment and other items, increasing cleaning difficulty and maintenance costs.

[0004] Therefore, a spraying device for metal sheet production is needed to solve the above problems. Utility Model Content

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a spraying device for metal plate production, which can realize automatic spraying of metal plates and prevent the sprayed paint from spreading in the air in the form of mist. It includes: a main unit 100, which includes a frame 101 and a spraying box 102 fixedly connected to the frame 101.

[0035] Multiple mounting units 200 disposed within the frame 101 are used to clamp metal plates; and

[0036] A rotating unit 300 disposed on the frame 101 is used to drive multiple sets of mounting units 200 to rotate. It includes a drive assembly and a baffle 305. The baffle 305 is used to support the mounting unit 200, and the rotating assembly is used to drive the baffle 305 to rotate.

[0037] The spraying unit 400 is installed inside the spraying box 102 and is used to spray paint on the metal plate.

[0038] In use, the metal plate is clamped and fixed by the installation unit 200, and then the metal plate is automatically sprayed with paint by the spraying unit 400. This solves the problems of slow speed and difficulty in ensuring the continuity and stability of spraying by manual operation, thereby improving the efficiency of spraying. Furthermore, the baffle 305 forms a sealed space between itself, the frame 101, and the spraying box 102, preventing the paint from spreading in the air in the form of mist. This solves the problem of paint particles polluting the air quality in the workshop, harming the health of workers, and potentially adhering to the surface of workshop equipment and other items, increasing the difficulty of cleaning and maintenance costs.

[0039] Example 2

[0040] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, each of the multiple installation units 200 includes a hydraulic rod 201 fixedly connected to the baffle 305. A fixing block 202 is fixedly installed on the telescopic end of each hydraulic rod 201. A fixing frame 203 is connected to the lower end of each fixing block 202 through a rotating rod. Threaded blocks 204 are fixedly connected to both sides of each fixing frame 203. A lead screw 205 is engaged with each threaded block 204. A clamping plate 206 is rotatably connected to one end of each lead screw 205.

[0041] Specifically, rotating the lead screw 205 causes the clamping plate 206 to move relative to the lead screw 204 through engagement with the threaded block 204, thereby clamping and fixing the metal plate; activating the hydraulic rod 201 can move the metal plate and adjust the distance between the metal plate and the atomizing spray gun 403, thus adjusting the spacing according to the different thicknesses of the metal plate.

[0042] Furthermore, a reduction motor 207 is fixedly installed on the upper end of each of the multiple fixed blocks 202. The output end of the reduction motor 207 passes through the fixed block 202 and is fixedly connected to the rotating rod. Each rotating rod is rotatably connected to the fixed block 202. The lower end of each of the multiple fixed frames 203 is provided with a limiting groove for limiting the clamping plate 206. The upper end of each of the multiple clamping plates 206 is slidably disposed in the limiting groove. Both sides of each of the multiple fixed frames 203 are provided with through holes that match the lead screw 205. One end of each lead screw 205 passes through the through hole.

[0043] Specifically, the geared motor 207 is started, and its output end drives the metal plate to rotate through the rotating rod, which works in conjunction with the spraying unit 400 to spray paint the metal plate.

[0044] Furthermore, the drive assembly includes a fixed cover 306 fixedly connected to the frame 101. A servo motor 301 is fixedly connected to the upper end of the fixed cover 306. The output end of the servo motor 301 passes through the fixed cover and is fixedly sleeved with a drive gear 302. A driven gear 303 is meshed on the drive gear 302. A rotating shaft 304 is fixedly inserted at the center of the driven gear 303.

[0045] Specifically, the servo motor 301 is started, and its output drives the drive gear 302 to rotate. The drive gear 302 drives the driven gear 303 to rotate. The driven gear 303 and the rotating shaft 304 drive the baffle 305 to rotate 180 degrees, thereby changing the position of the metal plate. One side is used to replace the metal plate, and the other side is used for painting at the same time, thereby improving the painting efficiency.

[0046] Preferably, the gear ratio between the driving gear 302 and the driven gear 303 is 1:3. According to the gear transmission principle, this method can reduce speed.

[0047] Furthermore, one end of the rotating shaft 304 passes through the fixed cover 306 and the frame 101 and is rotatably connected to the inner wall of the fixed cover 306 and the frame 101. The upper end of the rotating shaft 304 is rotatably connected to the inner wall of the fixed cover 306, and the lower end of the rotating shaft 304 is fixedly connected to the baffle 305, which is rotatably connected to the inner wall of the frame 101. The fixed cover 306 provides protection.

[0048] Furthermore, the spraying unit 400 includes a telescopic cylinder 401 fixedly embedded in the inner wall of the spraying box 102. A connecting plate 402 is fixedly installed on the telescopic end of the telescopic cylinder 401. Multiple atomizing spray guns 403 are installed at equal intervals on one side of the connecting plate 402. The metal plate is sprayed with paint through the atomizing spray guns 403.

[0049] Furthermore, a connecting pipe is fixedly embedded in the inner wall of the connecting plate 402, and a connecting pipe for connecting to the spraying equipment is fixedly installed on one side of the connecting pipe. One end of each of the multiple atomizing spray guns 403 is connected to the inside of the connecting pipe.

[0050] It should be noted that the spraying equipment includes a material cylinder and a feed pump. The material cylinder is used to store the paint, and then the feed pump delivers the paint to the atomizing spray gun 403 for spraying. This is a common and mature technology used by those in the field, and the specific structure and paint delivery route will not be described in detail.

[0051] Furthermore, a controller for controlling the entire device is fixedly installed on one side of the spraying box 102, and a transparent observation window 1021 is provided on one side of the spraying box 102. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described here.

[0052] During spraying, paint particles are sprayed out through the atomizing spray gun 403. At the same time, the telescopic cylinder 401 is activated, which drives the atomizing spray gun 403 to move up and down. Then, the reduction motor 207 is activated, and its output end drives the metal plate to rotate through the rotating rod. In conjunction with the atomizing spray gun 403, the metal plate is automatically sprayed with paint. This solves the problems of slow speed and difficulty in ensuring the continuity and stability of spraying when operating manually, thereby improving the efficiency of spraying.

[0053] In summary, a spraying device for metal sheet production uses a telescopic cylinder 401 to drive an atomizing spray gun 403 to move up and down, and a reduction motor 207 and a rotating rod to rotate the metal sheet. Simultaneously, the atomizing spray gun 403 sprays paint particles, automatically spraying the entire metal sheet. This solves the problems of slow manual operation and difficulty in ensuring the continuity and stability of spraying, thereby improving spraying efficiency and meeting the needs of large-scale production. Furthermore, the baffle 305 creates a sealed space between the baffle, the frame 101, and the spray box 102, preventing paint from spreading in the air in a mist form. This solves the problem of paint particles polluting the air quality in the workshop, harming the health of workers, and potentially adhering to the surfaces of workshop equipment and other items, reducing cleaning difficulty and maintenance costs.

[0054] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
