Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet cleaning devices, specifically to a metal coating spraying and cleaning device with anti-fingerprint lines. Background Technology

[0002] In the manufacturing process of building decorative panels, an anti-fingerprint metallic coating is often sprayed onto the surface to improve corrosion resistance, aesthetics, feel, and ease of cleaning. The cleanliness of the substrate surface before spraying is crucial to the adhesion and final quality of the coating. Any tiny residues of grease, dust, or particles can lead to defects such as pinholes and poor adhesion in the coating.

[0003] Currently, before applying anti-fingerprint coatings to metal plates, the common practice is to horizontally immerse the plate in an ultrasonic cleaning tank for degreasing and dust removal. However, some shortcomings have been found during use: When the board is placed horizontally, it is easy to form a blind zone for sound wave reflection on the surface, resulting in poor cleaning uniformity. Particles and oil droplets after peeling are re-adsorbed due to the lack of an inclined flow path, causing secondary pollution. After cleaning, the boards need to be manually removed and transferred to a separate rinsing station, which is a dispersed process, takes up a lot of space, and is inefficient.

[0004] To address this, we propose a metal coating spraying and cleaning device with fingerprint-resistant lines. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a metal coating spraying and cleaning device with anti-fingerprint lines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A metal coating spraying and cleaning device with fingerprint-resistant lines, comprising: Cleaning tank; A support frame symmetrically installed on the inner sidewall of the cleaning tank, and a top plate is installed on the support frame together; Slider, each of the sliders is slidably attached to the inner sidewall of the support frame; A placement frame is set at an angle, and both ends of the placement frame are connected by a coupling and a slider; An ultrasonic transducer is installed on the inner wall of the cleaning tank. A sliding hole is formed in the top wall of the top plate, and a movable block slides through the inner side wall of the sliding hole. A nozzle seat is installed on the bottom wall of the movable block. The support frame is equipped with a drive mechanism that moves the placement frame vertically to switch between different cleaning states.

[0007] Preferably, the driving mechanism includes a lead screw rotatably connected to the inner wall of the top of the support frame, the slider and the adjacent lead screw are threadedly connected, and a bevel gear is fixedly connected to the bottom end of the lead screw.

[0008] Preferably, the sidewall of the cleaning tank is rotatably connected to a main shaft, and two bevel gears are fixedly connected to the sidewall of the main shaft.

[0009] Preferably, each of the first bevel gears meshes with an adjacent second bevel gear, and a motor is installed on the side wall of the cleaning tank, with the output end of the motor coaxially fixed to the main shaft.

[0010] Preferably, multiple flushing nozzles are installed at an angle on the bottom of the nozzle holder, and the nozzle holder is connected to an external pump body through a connecting pipe to form an inclined flushing water flow.

[0011] Preferably, an electric push rod is installed on the top plate, and the movable end of the electric push rod is fixedly connected to the moving block.

[0012] Preferably, the top wall of the placement frame is symmetrically equipped with isolation plates, and the support frame has an inverted U-shaped structure.

[0013] Preferably, a drainage trough is slidably installed on the cleaning tank.

[0014] This utility model has the following beneficial effects: 1. This utility model sets the placement frame and the metal plate on it in an inclined state, so that during the ultrasonic cleaning process, the peeled stains and particles can slide down quickly along the inclined surface under the action of gravity, effectively avoiding the problem of secondary adhesion of dirt caused by the disturbance of the cleaning fluid when placed horizontally, and significantly improving the thoroughness and efficiency of cleaning. 2. The ultrasonic cleaning and tilting spray rinsing functions are integrated into the same device, and the workpiece is automatically lifted and lowered by a motor-driven lead screw and slider to switch between immersion cleaning and spray rinsing. This replaces the traditional decentralized processing mode that requires multiple independent workstations and workpiece transfer. It not only significantly reduces the equipment footprint, but also effectively avoids the risk of secondary contamination of workpieces during the transfer process. It realizes integrated operation from ultrasonic cleaning to rinsing, and improves cleaning efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 A metal coating spraying and cleaning device with anti-fingerprint lines, comprising: The structure inside the cleaning tank 1 in this device is all treated with anti-rust treatment. A support frame 2 is symmetrically installed on the inner side wall of the cleaning tank 1, and a top plate 3 is installed on the support frame 2. Slider 4, each slider 4 is slidably connected to the inner side wall of the support frame 2; The placement frame 14 is set at an angle, and the two ends of the placement frame 14 are fixedly connected to the connecting shafts 5. The connecting shafts 5 and the slider 4 are fixedly connected, or at least one of the connecting shafts 5 is fixedly connected to the slider 4 through a floating coupling / ball hinge, which allows the connecting shafts 5 and the placement frame 14 to have a small adaptive displacement to release internal stress and prevent jamming. The ultrasonic transducer 6 is electrically connected to an external ultrasonic generator. The ultrasonic transducer 6 and the ultrasonic generator together form an ultrasonic device, which is existing technology. Its principle, circuit structure, control method and application system are all mature. The ultrasonic transducer 6 is installed on the inner wall of the cleaning tank 1. A sliding hole 16 is opened on the top wall of the top plate 3. A movable block 17 slides through the inner side wall of the sliding hole 16. A nozzle seat 18 is installed on the bottom wall of the movable block 17. The support frame 2 is equipped with a drive mechanism that moves the placement frame 14 in the vertical direction to switch between different cleaning states.

[0019] The drive mechanism includes a lead screw 9 rotatably connected to the inner wall of the top of the support frame 2, a slider 4 and an adjacent lead screw 9 threadedly connected, and a bevel gear 13 fixed to the bottom end of the lead screw 9.

[0020] The side wall of the cleaning tank 1 is sealed and rotatably connected to the main shaft 10, and two bevel gears 11 are fixedly connected to the side wall of the main shaft 10.

[0021] Each bevel gear 11 meshes with the adjacent bevel gear 13. A motor 12 is installed on the side wall of the cleaning tank 1. The motor 12 is a forward and reverse motor, and its output end is coaxially fixed to the main shaft 10, meaning the rotation direction of the motor 12's output shaft is controllable. Specifically, by changing the direction of the current input to the motor 12 or controlling its wiring method, the main shaft 10 can be driven to rotate in the forward or reverse direction.

[0022] Multiple flushing nozzles 19 are installed at an angle on the bottom of the nozzle holder 18. The nozzle holder 18 has a flow distribution channel inside. The nozzle holder 18 is connected to an external pump body through a connecting pipe 15 so that an inclined flushing water flow can be formed after the external pump body is started.

[0023] An electric push rod 8 is installed on the top plate 3. The electric push rod 8 is model DTZ-100. The movable end of the electric push rod 8 is fixedly connected to the moving block 17.

[0024] The top wall of the placement frame 14 is symmetrically equipped with isolation plates 20, and the support frame 2 has an inverted U-shaped structure.

[0025] A drain trough 7 is slidably installed on the cleaning tank 1 (e.g. Figure 4 As shown, the drain trough 7 is detachably slidably mounted on the cleaning tank 1. The drain trough 7 can be completely removed during ultrasonic cleaning to make room for the lifting and lowering of the placement frame 14. When rinsing and water collection are required, it can be pushed into the appropriate position below the placement frame 14.

[0026] In this invention, the operator first places the metal sheet into the placement frame 14, ensuring that the surface to be coated with the anti-fingerprint line coating is tilted upwards.

[0027] When motor 12 is turned on, it is a reversible motor. The output end of motor 12 drives the main shaft 10, which is fixedly connected to it, to rotate. At this time, the main shaft 10 will drive the two bevel gears 11, which are fixedly connected to it, to rotate synchronously. Then, the two bevel gears 11 will drive the bevel gears 13, which are meshed with them, to rotate. In turn, each bevel gear 13 will drive the lead screw 9, which is fixedly connected to it, to rotate. This causes the slider 4, which is threaded to the side wall of the two lead screws 9, to move synchronously in the vertical direction. The slider 4 and the inner side wall of the support frame 2 are in contact and will not rotate.

[0028] When the two sliders 4 move downwards synchronously, they will drive the metal plate on the placement frame 14 to move downwards synchronously through the connecting shaft 5 connected to their side walls, until the metal plate is submerged in the cleaning fluid inside the cleaning tank 1. At this time, multiple ultrasonic transducers 6 are turned on. Since the metal plate is placed at an angle, it forms an angle with the direction of ultrasonic wave propagation in the cleaning fluid, which helps to form an uneven sound pressure distribution and may generate a more complex flow field. At the same time, most importantly, the tilted state can effectively promote the peeled dirt to slide down the inclined surface under the action of gravity, and prevent it from re-attaching on the horizontal surface due to disturbance, thereby improving the cleaning effect.

[0029] After ultrasonic cleaning for a period of time, the output end of motor 12 is reversed. The two sliders 4 will drive the placement frame 14 to move vertically upward through the corresponding connecting shaft 5. The placement frame 14 will then drive the metal plate to move upward synchronously until the end of the stroke. At this time, the external pump connected to the connecting pipe 15 is turned on, so that the external water is sprayed out from multiple rinsing nozzles 19 through the connecting pipe 15 and the nozzle seat 18. At this time, under the action of multiple isolation plates 20, the rinsing water is prevented from splashing into the cleaning tank 1, and the drain trough 7 is pushed so that the drain trough 7 collects and discharges the water on the placement frame 14.

[0030] When the electric push rod 8 is activated, its output end drives the movable block 17, which is fixedly connected to it, to move. The movable block 17 then drives the nozzle seat 18 and multiple rinsing nozzles 19 to move horizontally, thus facilitating the rinsing nozzles 19 to rinse the surface of the ultrasonically cleaned metal sheet again. The tilting spray of the rinsing nozzles 19, combined with the horizontal scanning motion driven by the electric push rod 8, can thoroughly rinse the surface of the metal sheet without dead angles, ensuring that the dirt removed by ultrasonic waves and the ultrasonic cleaning fluid are rinsed away, which is convenient for the subsequent spraying of the anti-fingerprint metal coating.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
