Description

Technical Field

[0001] This invention relates to the field of aluminum processing technology, specifically to an aluminum spraying device with a cleaning function. Background Technology

[0002] Aluminum materials are products made of aluminum and other alloying elements, with aluminum being the main metallic element. Aluminum materials have important applications in building materials, electronic products, packaging, and heat dissipation. During the production process of aluminum materials, operations such as painting are required on the surface of the formed aluminum materials to improve their rust resistance and wear resistance.

[0003] Existing aluminum coating devices lack cleaning functions for the workpieces being coated. Dust particles adhering to the workpiece surface lead to poor paint coating results, while manual cleaning results in low work efficiency. Furthermore, after coating one side of the aluminum material, existing devices require manual disassembly and reassembly, which also reduces production efficiency. In addition, some paint spills outside the workpiece during the coating process, and existing devices lack the ability to recycle this paint. Therefore, we propose an aluminum coating device with a cleaning function. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing systems and provide an aluminum coating device with a cleaning function. This device features a reliable mobile coating unit capable of flexibly moving the coating frame and the lower nozzle in both horizontal and vertical directions, effectively performing the coating operation. The device also includes a cleaning component that scrapes away dust and debris from the workpiece surface before coating, achieving a cleaning effect and allowing the paint to adhere better to the aluminum workpiece surface. After coating, the device can be connected to an external water source for cleaning. Furthermore, it has a reliable aluminum clamping unit that effectively fixes the aluminum workpiece and can flexibly flip it over, enabling multi-sided coating and reducing the inconvenience of frequent workpiece disassembly and flipping. A reliable paint cleaning unit effectively recovers any paint spilled outside the workpiece. Utilizing a discharge hole, airflow is directed upwards and blown onto the painted workpiece surface. Combined with the workpiece flipping, this achieves efficient drying of the paint on the aluminum surface, effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aluminum spraying device with a cleaning function, comprising a processing table, an aluminum clamping unit, a moving spraying unit, and a paint cleaning unit;

[0006] Processing table: It is a horizontal rectangular structure with a hollow interior. A plate-shaped mounting bracket is fixedly connected to the upper rear side of the processing table. A horizontal L-shaped receiving rack is fixedly connected to the upper end of the processing table, with the right end of the receiving rack higher than the left end.

[0007] Aluminum clamping unit: installed on the left and right sides of the receiving rack;

[0008] Mobile spraying unit: includes a connecting slide arm, a vertical slide, a limit lever, a lifting slide column, a spraying frame, a hydraulic cylinder, a scraper, and an electric push rod. The mounting frame has a horizontal mounting groove inside, with a horizontal T-shaped cross-section and the narrow end facing forward and connecting to the outside. A connecting slide arm, also with a T-shaped structure, is slidably connected inside the mounting groove. An electric push rod is embedded in the right side of the mounting frame, with its telescopic end facing left and fixedly connected to the right side of the connecting slide arm. The horizontal end of the connecting slide arm extends forward and is fixedly connected to a vertical slide at its end. The vertical slide arm is internally fixedly connected to... It is equipped with a vertical limiting rod, the lifting slide column is horizontally set and its rear end is slidably connected to the inside of the vertical slide frame, the limiting rod passes through the rear end of the lifting slide column and is slidably connected to the lifting slide column, the front end of the lifting slide column is fixedly connected to the rear end of the spray frame, the lower end of the spray frame is a concave arc structure, an arc-shaped nozzle is embedded in the middle side of the arc structure, and hydraulic cylinders and scrapers are embedded in the left and right sides of the spray frame. The scrapers are set longitudinally and are vertically slidably connected to the lower ends of the left and right sides of the spray frame. The hydraulic cylinders are set in the upper ends of the left and right sides of the spray frame, and their telescopic ends are fixedly connected to the scrapers with their extension ends facing downward.

[0009] Paint cleaning unit: installed inside the processing table and receiving rack.

[0010] The processing table and mounting frame together form the basic structure of this device. The receiving rack is used to collect excess paint sprayed out, and with the help of the paint cleaning unit, it can recover excess paint sprayed outside the workpiece. The aluminum clamping unit is used to clamp the aluminum workpiece and drive the workpiece to flip it over, so as to realize multi-sided spraying of the workpiece and reduce the trouble of workers frequently disassembling and flipping the workpiece. The electric push rod drives the connecting slide arm to slide laterally inside the mounting slide groove. The connecting slide arm is used for the installation of the vertical slide, and the vertical slide is used for the installation of the lifting slide column. The limit rod limits the lifting slide column and allows the lifting slide column to move vertically. The carriage slides up and down, causing the spraying frame to move downwards and closer to the aluminum workpiece. An arc-shaped nozzle is embedded in the middle of the arc-shaped structure at the lower end of the spraying frame, which can spray paint in a 180° range towards the center, thus effectively taking into account the sides of the aluminum workpiece. Driven by the power unit, the spraying frame can move and spray the aluminum workpiece. Before the spraying operation, the hydraulic cylinder can push the scraper downwards. The scraper adheres to the surface of the aluminum workpiece and, under the movement of the spraying frame, scrapes away dust and debris from the workpiece surface, achieving a cleaning effect on the surface to be sprayed, so that the paint can better adhere to the surface of the aluminum workpiece.

[0011] Furthermore, the mobile spraying unit also includes a feed pipe interface, a solenoid valve, a support plate, a hydraulic cylinder, and a pneumatic booster. Two feed pipe interfaces are fixedly connected to the upper end of the spraying frame. These interfaces are connected to the interior of the spraying frame via the solenoid valve. A pneumatic booster is installed on the rear side of the upper end of the spraying frame, with its air inlet facing upwards and its outlet leading into the internal chamber of the spraying frame. One feed pipe interface is used to connect to a feed pipe for connecting to an external paint source, and the other feed pipe interface is used to connect to an external water source for rinsing and cleaning the spraying frame and the lower receiving frame. The solenoid valve controls the opening and closing of the feed pipe interfaces. The pneumatic booster pressurizes the interior of the spraying frame, thereby improving the atomization effect of the sprayed paint. The support plate is used to install the hydraulic cylinder, which drives a lifting slide to move up and down, thus controlling the spraying frame to move closer to or further away from the workpiece surface.

[0012] Furthermore, the aluminum clamping unit includes a mounting slide, a hydraulic cylinder, a motor housing, a drive shaft, and a clamping block. A horizontal mounting slide is fixedly connected to the upper left side of the processing table. A hydraulic cylinder is embedded in the left side of the mounting slide. The motor housing is slidably connected inside the mounting slide. The telescopic end of the hydraulic cylinder faces right and is fixedly connected to the left side of the motor housing. An electric motor is embedded inside the motor housing. The output shaft of the electric motor faces right and is fixedly connected to a U-shaped clamping block at its end. Another clamping block is rotatably connected to the right side of the receiving rack via a rotating shaft. The two clamping blocks are at the same horizontal height. The mounting carriage is used for mounting the hydraulic cylinder and the motor housing. The motor housing is used to mount the internal motor. The clamping block is installed at the end of the motor output shaft and is initially placed horizontally. The hydraulic cylinder can push the motor housing to slide to the right, and make the clamping block at the end of the motor lock onto the left end of the aluminum workpiece. Together with the clamping block fixed on the right side, they clamp and fix the aluminum workpiece. After one side is sprayed, by controlling the motor inside the motor housing, the aluminum workpiece can be flexibly flipped, thereby realizing multi-sided spraying of the workpiece and reducing the trouble of workers frequently disassembling and flipping the workpiece.

[0013] Furthermore, the aluminum clamping unit also includes an installation sleeve, a vertical slide rod, a spring, a pressure block, and a lifting rod. The upper end of the clamping block is fixedly connected to the installation sleeve, and the vertical slide rod is slidably connected inside the installation sleeve. A circular pressure block is fixedly connected to the lower end of the vertical slide rod, and a spring is fitted around the outside of the vertical slide rod. The upper end of the spring is engaged inside the installation sleeve, and the lower end of the installation sleeve rests against the upper side of the pressure block. A lifting rod is fixedly connected to the upper end of the vertical slide rod. The installation sleeve is used to install the vertical slide rod and engage the upper end of the spring. Under the action of the spring, the vertical slide rod pushes the pressure block to press against the upper end of the aluminum workpiece, thus fixing the workpiece vertically and further improving the workpiece's fixing effect.

[0014] Furthermore, the paint cleaning unit includes an arc-shaped heating plate, a hydraulic cylinder, a scraper block, and a drain hole. A semi-circular horizontal groove is formed on the upper side of the receiving rack. A row of square drain holes is linearly arranged at the bottom of the semi-circular horizontal groove, extending downwards and connecting to a hollow area inside the processing table. An arc-shaped heating plate is installed on the bottom arc surface of the semi-circular horizontal groove. A hydraulic cylinder is fixedly installed on the right side of the receiving rack. The telescopic end of the hydraulic cylinder extends to the left into the horizontal groove, and a scraper block is fixedly connected to its end. The scraper block has a half-ring structure, and its lower edge fits against the arc surface of the semi-circular horizontal groove. The arc-shaped heating plate keeps the paint in a liquid state through heating, facilitating scraping. The hydraulic cylinder pushes the scraper block to slide inside the receiving rack, scraping and pushing the liquid paint into the drain hole, where it is collected by the collection device below, thus achieving paint cleaning and recycling.

[0015] Furthermore, the paint cleaning unit also includes a support carriage and an air guide plate. The interior of the processing table is a square hollow area. An L-shaped support carriage is fixedly connected to each of the left and right corners of the upper side of the hollow area. The air guide plate slides longitudinally between the two support carriages, with its two ends slidably connected to the inner corners of the two support carriages respectively. The air guide plate is hollow inside and has air outlets at its upper end, the same number as the material leakage holes. Each air outlet vertically corresponds to one material leakage hole. The support carriages support the air guide plate and allow it to slide longitudinally. When the air guide plate retracts backward, it keeps the material leakage holes unobstructed. When the air guide plate extends forward, it vertically aligns the upper air outlets with the material leakage holes, thus achieving connection of the air supply channel.

[0016] Furthermore, the paint cleaning unit also includes a second tray and a blower. The second tray is fixedly connected to the rear side of the processing table, and the blower is installed on the upper end of the second tray. The air outlet of the blower is connected to the inside of the air guide plate through an air supply hose. The second tray is used for installing the blower. The blower delivers air to the inside of the air guide plate through the air supply hose. The air is delivered upward along the air outlet and the material leakage hole, and blown onto the surface of the workpiece after the paint has been sprayed. Combined with the workpiece flipping effect, this enables efficient air drying of the paint on the aluminum surface.

[0017] Furthermore, the paint cleaning unit also includes a fixing frame and a hydraulic cylinder. A U-shaped fixing frame is fixedly connected to the rear side of the processing table and above the blower. The fixing frame is arranged longitudinally and the hydraulic cylinder is installed inside. The telescopic end of the hydraulic cylinder extends forward into the interior of the processing table and is fixedly connected to the rear end of the air guide plate. The fixing frame is used for mounting the hydraulic cylinder, which provides the power required for the movement of the air guide plate.

[0018] Furthermore, the paint cleaning unit also includes a collection box and a pull ring. The collection box is placed on the lower side of the hollow area inside the processing table, vertically corresponding to the leakage hole, and a pull ring is fixedly connected to the middle of the front end of the collection box. The collection box is used to hold the collected paint, and the pull ring allows the collection box to be easily pulled out.

[0019] Furthermore, the aluminum clamping unit also includes a bearing. A semi-circular groove is provided on the upper left side of the receiving frame, and the bearing is installed inside the groove. The outer ring of the bearing is fixedly connected to the arc surface of the semi-circular groove. The drive shaft passes through the inner ring of the bearing and maintains a sliding connection with the bearing. The bearing allows the drive shaft to slide laterally while supporting it, effectively protecting the drive shaft from being damaged by the weight of the workpiece.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: This aluminum spraying device with cleaning function has the following advantages.

[0021] 1. It has a reliable mobile spraying unit that can drive the spraying frame and the lower nozzle to move flexibly in both horizontal and vertical directions, effectively performing the spraying operation. The arc-shaped nozzle can spray the paint in a 180° range towards the center, thus effectively taking into account the sides of the aluminum workpiece. Before the spraying operation, the hydraulic cylinder can push the scraper downwards. The scraper adheres to the surface of the aluminum workpiece and, under the action of the moving spraying frame, scrapes away the dust and debris on the surface of the workpiece, achieving a cleaning effect on the surface to be sprayed. This allows the paint to better adhere to the surface of the aluminum workpiece. After spraying, it can be connected to an external water source to clean the device.

[0022] 2. It has a reliable aluminum clamping unit that can clamp aluminum workpieces horizontally and fix them vertically, so that the workpieces can be effectively fixed.

[0023] 3. It has a reliable paint cleaning unit that can effectively recover and process paint that has fallen outside the workpiece; and by using the discharge hole, it can deliver air upward and blow it onto the surface of the workpiece after the paint has been sprayed. With the workpiece being flipped, it can achieve efficient air drying of the paint on the aluminum surface.

[0024] 4. This invention features a reliable mobile spraying unit capable of flexibly moving the spraying frame and the lower nozzle in both horizontal and vertical directions, effectively executing the spraying operation. The arc-shaped nozzle can spray paint in a 180° range towards the center, effectively covering the sides of the aluminum workpiece. Before spraying, the hydraulic cylinder pushes the scraper downwards, which adheres to the surface of the aluminum workpiece and, under the movement of the spraying frame, scrapes away dust and debris, cleaning the surface to be sprayed and allowing the paint to adhere better to the aluminum workpiece surface. It also features a reliable aluminum clamping mechanism. The assembly unit can clamp aluminum workpieces horizontally and fix them vertically, ensuring effective workpiece secureness. After one side is coated, the motor inside the motor housing can be controlled to flexibly flip the aluminum workpiece, enabling multi-sided coating and reducing the hassle of frequent disassembly and flipping by workers. It also features a reliable paint cleaning unit that effectively recovers paint spilled outside the workpiece. Furthermore, using a discharge port, airflow is directed upwards and blown onto the painted surface of the workpiece, achieving efficient drying of the paint on the aluminum surface in conjunction with the workpiece's flipping.

Before the spraying operation, the hydraulic cylinder 56 can push the scraper 57 downward. The scraper 57 adheres to the surface of the aluminum workpiece and, under the movement of the spraying frame 55, scrapes away dust and debris on the surface of the workpiece, achieving a cleaning effect on the surface to be sprayed, thereby allowing the paint to adhere better. The aluminum workpiece surface can be cleaned by connecting to an external water source after spraying: the processing table 1 and the mounting frame 2 together form the basic frame of this device; the receiving rack 3 is used to collect excess sprayed paint, and under the action of the paint cleaning unit 6, it can recycle excess paint sprayed outside the workpiece; the aluminum clamping unit 4 is used to clamp the aluminum workpiece and drive the workpiece to flip it over, so as to realize multi-sided spraying of the workpiece and reduce the trouble of workers frequently disassembling and flipping the workpiece; the electric push rod 513 drives the connecting slide arm 51 to slide laterally inside the mounting slide groove; the connecting slide arm 51 is used for the installation of the vertical slide 52; the vertical slide 52 is used for raising and lowering the slide column 5. The installation of 4, the limiting rod 53 limits the lifting slide column 54, and allows the lifting slide column 54 to slide up and down along the vertical slide frame 52, thereby driving the spray frame 55 to move downward and closer to the aluminum workpiece. The lower end of the spray frame 55 has an arc-shaped nozzle embedded in the middle side of the arc structure, which can spray paint in a 180° range towards the center, thus effectively taking into account the side of the aluminum workpiece. Driven by the power unit, the spray frame 55 can move and spray the aluminum workpiece. Before the spraying operation, the hydraulic cylinder 56 can push the scraper 57 downward. The scraper 57 sticks to the surface of the aluminum workpiece, and under the movement of the spray frame 55, it removes dust and debris from the surface of the workpiece. The process involves scraping to clean the surface to be sprayed, allowing the paint to adhere better to the aluminum workpiece surface. One feed pipe interface 58 is used to connect to the feed pipe for connecting to an external paint source, and the other feed pipe interface 58 is used to connect to an external water source for rinsing and cleaning the spray frame 55 and the lower receiving rack 3. The solenoid valve 59 is used to control the opening and closing of the feed pipe interface 58. The pneumatic booster 512 pressurizes the inside of the spray frame 55 to improve the atomization effect of the sprayed paint. The first support plate 510 is used to install the third hydraulic cylinder 511. The third hydraulic cylinder 511 drives the lifting slide column 54 to move up and down, thereby controlling the spray frame 55 to move closer to or away from the workpiece surface.This device also features a reliable aluminum clamping unit 4, capable of horizontally clamping and vertically fixing aluminum workpieces, ensuring effective workpiece fixation. Furthermore, once one side is coated, controlling the motor inside the motor housing 43 allows for flexible flipping of the aluminum workpiece, enabling multi-sided coating and reducing the need for frequent workpiece disassembly and flipping. The mounting carriage 41 is used for mounting the hydraulic cylinder 42 and the motor housing 43. The motor housing 43 houses the internal motor, and the clamping block 46 is mounted on the end of the motor output shaft, initially positioned horizontally. The hydraulic cylinder 42 pushes the motor housing 43 to slide to the right, thus enabling the motor to... The clamping block 46 at the end of the machine is engaged with the left end of the aluminum workpiece, and together with the clamping block 46 fixed on the right side, they clamp and fix the aluminum workpiece. After one side is coated, the motor inside the motor box 43 is controlled to flexibly flip the aluminum workpiece, thereby achieving multi-sided coating of the workpiece and reducing the trouble of workers frequently disassembling and reassembling the workpiece to flip it. The mounting sleeve 47 is used for the installation of the vertical slide rod 48 and is engaged with the upper end of the spring 49. Under the action of the spring 49, the vertical slide rod 48 pushes the pressure block 410 to press against the upper end of the aluminum workpiece, which can fix the workpiece from the vertical direction, thereby further improving the fixing effect of the workpiece. This device also features a reliable paint cleaning unit 6, capable of effectively recovering paint spilled outside the workpiece; and utilizing the discharge hole 64, it can deliver upward airflow onto the surface of the workpiece after painting, achieving efficient air drying of the paint on the aluminum surface in conjunction with the workpiece's rotation; the arc-shaped heating plate 61 keeps the paint in a liquid state through heating, facilitating scraping; the hydraulic cylinder 62 pushes the scraper block 63 to slide inside the receiving rack 3, scraping and pushing the liquid paint into the discharge hole 64, where it is collected by the collection device below, thus achieving paint cleaning and recovery; the supporting carriage 67 supports the air guide plate 68 and guides the air flow. The air deflector 68 can slide longitudinally. The fixed frame 611 is used for the installation of hydraulic cylinder 612, which provides the power required for the movement of the air deflector 68. When the air deflector 68 retracts backward, it keeps the material leakage hole 64 unobstructed. When the air deflector 68 extends forward, it aligns the upper air outlet vertically with the material leakage hole 64, thus connecting the air supply channel. The support plate 69 is used for the installation of the blower 610. The blower 610 delivers air to the inside of the air deflector 68 through the air supply hose. The air is delivered upward along the air outlet and the material leakage hole 64 and blown onto the surface of the workpiece after the paint is sprayed. Combined with the workpiece flipping effect, it can achieve efficient air drying of the paint on the aluminum surface. In addition, the bearing 45 can support the drive shaft 44 while allowing the drive shaft 44 to slide laterally. By supporting the drive shaft 44, it can effectively protect the drive shaft 44 from being crushed by the weight of the workpiece.
