Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices, specifically a pre-dust removal device for coating primer on colored aluminum coils. Background Technology

[0002] Color-coated aluminum coils are aluminum coil products coated with a colored coating. They are typically made from aluminum coils through surface treatment and coating processes. Color-coated aluminum coils possess excellent weather resistance, corrosion resistance, and decorative properties, and are widely used in architectural decoration, electronics, automobile manufacturing, and household appliances. Common types of color-coated aluminum coils include coated aluminum coils, color-coated aluminum coils, and paint-coated aluminum coils. During the production and processing of color-coated aluminum coils, a primer coating is required. To improve the primer coating effect, dust removal is necessary before coating the aluminum coils.

[0003] Currently, when using dust removal equipment, if the aluminum coil becomes curled or wrinkled, dust and impurities adhere to the bends, affecting the subsequent dust removal and cleaning effect. Furthermore, the dust and impurities removed from the aluminum coil tend to scatter, making subsequent collection and processing inconvenient. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-dust removal device for the primer coating of colored aluminum coils, which solves the problem that the curling and wrinkles of colored aluminum coils affect the dust removal effect, and also solves the problem that it is inconvenient to collect and process the dust and impurities that are cleaned out.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-dust removal device for coating primer on colored aluminum coils, comprising a cabinet, a plurality of evenly distributed support rods fixedly connected to the bottom of the cabinet, anti-slip pads fixedly connected to the bottom of the support rods, guide rollers rotatably sleeved inside the cabinet, a box fixedly connected to the top of the cabinet, a fixed seat fixedly connected inside the cabinet, brush bristles provided inside the fixed seat, a leveling mechanism provided on the cabinet, and a dust collection mechanism provided on the box.

[0006] Preferably, there are multiple anti-slip mats, and the anti-slip mats are made of rubber. By designing anti-slip mats, the overall structural anti-slip stability can be improved.

[0007] Preferably, the leveling mechanism includes connecting sleeves. Two symmetrically distributed connecting sleeves are rotatably fitted inside the cabinet via bearings. A handle is fixedly connected to the outer side of each connecting sleeve, and the handle is rotatably connected to the cabinet via bearings. A screw is threadedly connected inside each connecting sleeve, and a bracket is fixedly connected to the outer side of the screw. A leveling roller is rotatably fitted inside the bracket, and a guide rod is fixedly connected to the outer side of the leveling roller. The guide rod is slidably connected to the cabinet. By designing this leveling mechanism, the aluminum coil can be leveled and dusted.

[0008] Preferably, the cabinet has a guide groove inside, and a guide rod is slidably connected inside the guide groove. By designing the guide groove, the guide rod can slide along the guide groove h.

[0009] Preferably, the dust collection mechanism includes an air pump, which is fixedly connected inside the housing. The air pump has an air inlet at its lower end. Multiple filter plates are slidably fitted inside the housing, and support sleeves are slidably fitted onto the outer sides of the filter plates. The support sleeves are fixedly connected to the housing. A connecting pipe is fixedly connected to the lower end of the housing, and multiple guide ports are fixedly connected inside the fixed base. This dust collection mechanism facilitates the recovery and cleaning of dust and impurities.

[0010] Preferably, the air pump has an exhaust port on its right end, and the exhaust port is fixedly connected to the housing. By designing the exhaust port, the gas inside the housing can be discharged.

[0011] Preferably, the connecting pipe is fixedly connected to the cabinet body and the fixing base. By designing the connecting pipe, dust and impurities can be extracted through it.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes the design of brush bristles. When the aluminum coil is conveyed by the drive device, the aluminum coil will slide relative to the brush bristles. The brush bristles can sweep away the dust and impurities attached to the surface of the aluminum coil, achieving the purpose of dust removal. During dust removal, the air pump can draw air from the outside through the guide port, so that the swept dust and impurities can be drawn into the box for filtration and collection, avoiding the problem of dust and impurities being difficult to recycle and clean after dust removal.

[0014] 2. This utility model, through the design of the leveling roller, allows the aluminum coil to slide relative to the leveling roller during conveying. The movement of the aluminum coil causes the leveling roller to rotate, which can level the moving aluminum coil. This avoids the problem of dust adhering to the curved parts due to the curling and wrinkles of the aluminum coil, thus affecting the dust removal effect. In addition, the distance between the two leveling rollers can be adjusted to facilitate the leveling of aluminum coils of different sizes and thicknesses. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 A pre-dust removal device for coating primer on colored aluminum coils includes a cabinet 1. Multiple evenly distributed support rods 2 are fixedly connected to the bottom of the cabinet 1. Anti-slip pads 3 are fixedly connected to the bottom of each support rod 2. The anti-slip pads 3 are made of rubber. The design of the anti-slip pads 3 improves the overall anti-slip stability of the structure. A guide roller 4 is rotatably sleeved inside the cabinet 1. A box 5 is fixedly connected to the top of the cabinet 1. A fixed seat 6 is fixedly connected inside the cabinet 1. Brush bristles 7 are installed inside the fixed seat 6. A leveling mechanism 8 is installed on the cabinet 1, and a dust collection mechanism 9 is installed on the box 5.

[0022] Please see Figure 1 , Figure 2 The leveling mechanism 8 includes a connecting sleeve 81. Inside the cabinet 1, two symmetrically distributed connecting sleeves 81 are rotatably connected via bearings. A handle 82 is fixedly connected to the outside of the connecting sleeve 81. The handle 82 is rotatably connected to the cabinet 1 via bearings. Inside the connecting sleeve 81, a screw 83 is threadedly connected. Outside the screw 83, a bracket 84 is fixedly connected. Inside the bracket 84, a leveling roller 85 is rotatably connected. Outside the leveling roller 85, a guide rod 86 is fixedly connected. The guide rod 86 is slidably connected to the cabinet 1. Inside the cabinet 1, a guide groove 87 is provided. Inside the guide groove 87, the guide rod 86 is slidably connected. By designing the guide groove 87, the guide rod 86 can slide along the guide groove 87. By designing the leveling mechanism 8, the aluminum coil can be leveled and dusted.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The dust collection mechanism 9 includes an air pump 91, which is fixedly connected inside the housing 5. The lower end of the air pump 91 has an air inlet 92, and the right end of the air pump 91 has an exhaust port 93. The exhaust port 93 is fixedly connected to the housing 5. By designing the exhaust port 93, the gas inside the housing 5 can be discharged. Multiple filter plates 94 are slidably sleeved inside the housing 5. Support sleeves 95 are slidably sleeved on the outer side of the filter plates 94. The support sleeves 95 are fixedly connected to the housing 5. A connecting pipe 96 is fixedly connected to the lower end of the housing 5. The connecting pipe 96 is fixedly connected to the cabinet 1 and the fixed base 6. By designing the connecting pipe 96, dust and impurities can be sucked up through the connecting pipe 96. Multiple guide ports 97 are fixedly connected inside the fixed base 6. By designing the dust collection mechanism 9, it is convenient to collect and clean dust and impurities.

[0024] The specific implementation process of this utility model is as follows: In use, the aluminum coil passes between two leveling rollers 85, allowing the aluminum coil to contact the brush bristles 7. Finally, the aluminum coil passes through the upper part of the guide roller 4. Subsequently, the driving device drives the aluminum coil to move, and the aluminum coil slides relative to the leveling rollers 85. The movement of the aluminum coil causes the leveling rollers 85 to rotate. The leveling rollers 85 can level the moving aluminum coil, avoiding the problem of dust adhering to the curved parts due to the curling and wrinkling of the aluminum coil, which affects the dust removal effect. When the handle 82 is turned, the handle 82 can drive the connecting sleeve 81 to rotate, which can cause the screw 83 to make a threaded movement. The screw 83 will drive the bracket 84 to move, and the bracket 84 will drive the leveling rollers 85 to move. At the same time, the bracket 84 will drive the guide rod 86 to slide along the guide groove 87, so that the distance between the two leveling rollers 85 can be adjusted to facilitate the leveling of aluminum coils of different sizes and thicknesses.

[0025] As the aluminum coil moves, it slides relative to the brush bristles 7, which clean the dust and impurities adhering to the surface of the aluminum coil, thus achieving the purpose of dust removal. During dust removal, the air pump 91 works simultaneously, drawing air into the housing 5 through the air inlet 92, creating a negative pressure inside the housing 5. Then, it draws air into the fixed base 6 through the connecting pipe 96, and then draws air out through the guide port 97, so that the dust and impurities cleaned from the surface of the aluminum coil are drawn into the housing 5 along with the air. Under the action of the filter plate 94, the dust and impurities are filtered and retained inside the housing 5, while the gas is discharged through the exhaust port 93, which facilitates the collection of the cleaned dust and impurities and avoids the problem of inconvenient subsequent cleaning of dust and impurities.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
