Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, and in particular to a brush roller structure applied to aluminum sheet materials. Background Technology

[0002] Stamping line cleaning machines are essential equipment in metal sheet processing, used to remove oil, oxide layers, debris, and other impurities from the sheet surface to ensure the quality of subsequent stamping or coating. The brush roller, as its core component, directly affects the cleaning effect and equipment efficiency. The bristles are commonly made of nylon, and high-density bristles are generally used to enhance cleaning power; the hardness is adjusted according to the surface of the sheet material.

[0003] Traditional brush rollers easily accumulate residues such as aluminum powder and rolling oil during the cleaning process. If not cleaned in time, these residues will adhere to the gaps between the bristles, causing secondary contamination and resulting in defects such as black streaks and dents on the aluminum plate surface. During high-pressure cleaning, if the bristle material is not selected properly, it may scratch the aluminum plate surface, affecting the quality of subsequent coating or welding. Nylon brush rollers are prone to softening and deformation under high-temperature cleaning environments, leading to a decrease in bristle rigidity and reduced cleaning efficiency.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Traditional brush rollers are prone to accumulating aluminum powder, rolling oil and other residues during the cleaning process. If not cleaned in time, the residues will adhere to the gaps between the brush bristles, causing secondary pollution and resulting in defects such as black streaks and dents on the surface of the aluminum plate. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that traditional brush rollers are prone to accumulating aluminum powder, rolling oil and other residues during the cleaning process. If they are not cleaned in time, the residues will adhere to the gaps between the brush bristles, causing secondary pollution and causing defects such as black streaks and dents on the surface of the aluminum plate. To this end, we propose a brush roller structure for aluminum plate materials.

[0006] To achieve the above objectives, this application adopts the following technical solution: a brush roller structure for aluminum plate materials, including a shaft core: both ends of the shaft core are fixedly connected to a connecting shaft, the surface of the shaft core is threaded with three strands of columns, the surface of the three strands of columns is equipped with several mounting blocks, the surface of the several mounting blocks is equipped with brush bristles, the brush bristles are made of a mixture of high-temperature resistant nylon and composite carbon fiber, the surface of the connecting shaft is provided with a connecting groove, the length of the brush bristles is 20-25cm, and the distance between two adjacent brush bristles is 10cm.

[0007] Preferably, the surface of the mounting block is coated with a conductive fiber layer, which is made of a mixture of silver, copper and nickel, and the conductive fiber layer is grounded through an external device connected to the connecting shaft.

[0008] Preferably, the surface of the shaft core is provided with an anti-rust coating, which is an epoxy zinc-rich paint.

[0009] Preferably, the surface of the shaft core is provided with a number of weight-reducing holes, which are distributed in a linear array on the shaft core.

[0010] Preferably, a waterproof and dustproof sealing ring is provided at the connection between the shaft core and the connecting shaft.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, high-temperature resistant nylon and composite carbon fiber bristles, with their excellent wear resistance and corrosion resistance, enable high-precision cleaning in the high-temperature production environment of aluminum plates. The high-strength shaft core, combined with the connecting shaft, effectively enhances structural rigidity and avoids deformation problems due to long shaft spacing. At the same time, the bristles, which are spirally wound and installed on three columns, ensure that the bristles are evenly distributed and not easily fall off, avoiding the shedding of bristles that occurs with traditional straight-insertion brush rollers. Furthermore, the bristles are set with specific values, which not only expands the cleaning coverage area and improves the efficiency of stain removal, but also avoids the problem of aluminum powder, rolling oil, and other residues remaining on the bristles due to excessively dense bristles, or cleaning blind spots caused by excessively sparse bristles, thus improving the practicality of the device.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Reference Figure 1-5 As shown, this utility model provides a technical solution: a brush roller structure applied to aluminum plate material, including a shaft core 1: both ends of the shaft core 1 are fixedly connected to a connecting shaft 2, the surface of the shaft core 1 is threaded with a three-strand column 3, the surface of the three-strand column 3 is equipped with a number of mounting blocks, the surface of the mounting blocks is equipped with brush bristles 5, the brush bristles 5 are made of a mixture of high temperature resistant nylon and composite carbon fiber, the surface of the connecting shaft 2 is provided with a connecting groove, the length of the brush bristles 5 is 20-25cm, and the distance between two adjacent brush bristles 5 is 10cm. With high-temperature resistant nylon and composite carbon fiber bristles 5, the device can perform high-precision cleaning in the high-temperature production environment of aluminum plates thanks to its excellent wear resistance and corrosion resistance. The high-strength shaft core 1, combined with the connecting shaft 2, effectively enhances the structural rigidity and avoids deformation problems due to long shaft distance. At the same time, the bristles 5, which are threaded and installed on the three-strand column 3, ensure that the bristles are evenly distributed and not easy to fall off, avoiding the shedding of bristles that occurs with traditional straight-insertion brush rollers. In addition, the bristles 5 are set with specific values, which not only expands the cleaning coverage area and improves the efficiency of stain grabbing, but also avoids the problem of aluminum powder, rolling oil and other residues remaining on the bristles if the bristles 5 are too dense, or the cleaning blind spots caused by too sparse bristles, thus improving the practicality of the device.

[0022] Reference Figure 4 As shown in this embodiment: the surface of the mounting block is coated with a conductive fiber layer, which is made of a mixture of silver, copper, and nickel. The conductive fiber layer is grounded through an external device connected to the connecting shaft 2. The coating of the mounting block with a conductive fiber layer made of silver, copper, and nickel, and its grounding via the external device connected to the connecting shaft 2, allows for the rapid discharge of static electricity generated during the operation of the brush roller, preventing dust from being attracted by static electricity and affecting the cleaning quality of the aluminum plate. It also eliminates safety hazards caused by electrostatic sparks, improving the practicality of the device.

[0023] Reference Figure 1 , Figure 3 and Figure 5As shown in this embodiment: the surface of the shaft core 1 is coated with an anti-rust coating, which is an epoxy zinc-rich paint. The epoxy zinc-rich paint anti-rust coating on the surface of the shaft core 1 provides both electrochemical protection and a physical barrier. Due to the sacrificial anode properties of zinc metal, the coating preferentially consumes itself to protect the shaft core 1 substrate under humid or corrosive conditions. Combined with the dense physical barrier properties of the paint film, it effectively resists corrosion from cutting fluids, oils, and other media in the aluminum plate processing environment. Simultaneously, it avoids problems such as loosening of the brush bristles 5 and eccentric operation caused by rust on the shaft core 1, thus improving the practicality of the device.

[0024] Reference Figure 5 As shown in this embodiment, the surface of the shaft core 1 is provided with a plurality of weight-reducing holes 8, which are arranged in a linear array on the shaft core 1. The linear array of weight-reducing holes 8 on the surface of the shaft core can reduce the overall weight and rotational inertia while ensuring structural strength, making the brush roller more stable during high-speed rotation. This also reduces material consumption, improves equipment operating efficiency, and lowers production costs.

[0025] Reference Figure 2 As shown in this embodiment, a waterproof and dustproof sealing ring 7 is provided at the connection between the shaft core 1 and the connecting shaft 2. By tightly fitting the joint between the shaft core 1 and the connecting shaft 2, the sealing ring effectively prevents the intrusion of contaminants such as cutting fluid, metal shavings, and dust during aluminum plate processing, thus improving the practicality of the device.

[0026] Working Principle: Through the coordinated operation of multiple components, efficient cleaning of aluminum plates and stable equipment operation are achieved. In terms of cleaning function, the bristles 5, made of a mixture of high-temperature resistant nylon and composite carbon fiber, possess excellent wear and corrosion resistance. With a length of 20-25cm and a spacing of 10cm, they form a reasonable cleaning coverage surface during high-speed rotation, effectively capturing stains from the aluminum plate surface. The threaded installation method, with the bristles 5 evenly distributed and firmly attached to the three-strand column 3, ensures that the bristles 5 remain firmly in place and do not fall off. Simultaneously, the conductive fiber layer on the surface of the mounting block, through the conductive properties of the silver, copper, and nickel mixture, conducts static electricity generated during operation to ground via the connecting shaft 2, preventing static electricity from attracting dust and affecting the cleaning effect, and eliminating the risk of electrostatic sparks.

[0027] In terms of structural stability and protection, the high-strength shaft core 1, combined with the connecting shaft 2, enhances the overall rigidity. The epoxy zinc-rich paint anti-rust coating on the surface of the shaft core 1 utilizes the sacrificial anode properties of zinc and the physical isolation of the paint film to resist corrosive media in the processing environment. The weight-reducing holes 8 opened in the shaft core 1 reduce rotational inertia while ensuring strength, making high-speed rotation smoother. The waterproof and dustproof sealing ring 7 at the connection between the shaft core 1 and the connecting shaft 2 fits tightly to the joint, preventing the intrusion of contaminants such as cutting fluid and metal shavings, avoiding wear and corrosion of the bearings and shaft core 1, ensuring the long-term stable operation of the brush roller, and providing reliable support for aluminum plate cleaning operations.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
