Description

Technical Field

[0001] This utility model relates to the field of aluminum profiles, specifically to an aluminum profile surface pretreatment device. Background Technology

[0002] Aluminum profiles are metal materials with different cross-sectional shapes, made primarily from aluminum rods through a hot-melt extrusion process. Their core advantages lie in their lightweight (density only 1 / 3 that of steel), high strength, and corrosion resistance. The surface can be enhanced with processes such as anodizing and electrophoretic coating to improve aesthetics and durability. Based on their applications, they can be divided into three main categories: architectural profiles (such as doors, windows, and curtain walls), industrial profiles (mechanical equipment frames, rail transit components), and decorative profiles.

[0003] For example, authorization announcement number CN112354764B discloses a surface pretreatment device for aluminum profile processing, relating to the field of aluminum profile processing technology. This device includes a second and third connecting shaft, a second and third transmission wheel, a first and second transmission belt, a first and fourth transmission wheel, a fourth connecting shaft, a connecting roller, and a cleaning brush. While cleaning the outer surface of the aluminum profile, the device then conveys the aluminum profile to the left. Simultaneously, a controller operates an air pump to blow impurities from the aluminum profile into a collection box. This solves the problem that existing aluminum profile surface spraying equipment often lacks the function of cleaning the aluminum profile surface, requiring manual cleaning before spraying, thus increasing the workload for workers.

[0004] Because aluminum profiles are coated with grease for oxidation prevention before processing, the pretreatment devices in the above technologies only remove dust from the aluminum profile surface using a cleaning brush and an air pump, but cannot remove the grease, which affects subsequent processing. Therefore, the market urgently needs to develop an aluminum profile surface pretreatment device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum profile surface pretreatment device to solve the problem mentioned in the background art that, because the surface of aluminum profiles is covered with grease for anti-oxidation before processing, the existing pretreatment devices only use a cleaning brush and an air pump to remove dust from the surface of the aluminum profiles, but cannot remove the grease from the surface of the aluminum profiles, which affects subsequent processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum profile surface pretreatment device, comprising a pretreatment box, wherein brush rollers are rotatably connected to both the front and rear ends of the middle part of the pretreatment box, a U-shaped cleaning liquid conveying pipe is fixedly connected to one side of the middle part of the pretreatment box, a U-shaped clean water conveying pipe is fixedly connected to the other side of the middle part of the pretreatment box, and strip guide frames are fixedly connected to both the upper and lower ends of the middle part of the pretreatment box, and multiple conveying rollers are rotatably connected at equal intervals on the inner sides of the two strip guide frames.

[0018] 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.

[0019] Please see Figure 1-6 This utility model provides an embodiment of an aluminum profile surface pretreatment device, comprising a pretreatment box 1. Brush rollers 3 are rotatably connected to both the front and rear ends of the center of the pretreatment box 1. A U-shaped cleaning fluid conveying pipe 5 is fixedly connected to one side of the center of the pretreatment box 1, and a U-shaped clean water conveying pipe 6 is fixedly connected to the other side of the center of the pretreatment box 1. Strip guide frames 2 are fixedly connected to both the upper and lower ends of the center of the pretreatment box 1. Multiple conveying rollers 201 are rotatably connected at equal intervals to the inner sides of the two strip guide frames 2. The two strip guide frames 2 pass through the space between the two brush rollers 3, the inner side of the U-shaped cleaning fluid conveying pipe 5, and the inner side of the U-shaped clean water conveying pipe 6. Rectangular openings 101 are provided in the center of the end faces of both sides of the pretreatment box 1. The two strip guide frames 2 extend out of the pretreatment box 1 through two rectangular openings 101 on the sides. The rear end of each of the two strip guide frames 2 is fixedly connected to a drive mechanism 202 for simultaneously driving multiple conveying rollers 201 to rotate. An aluminum profile plate 203 is provided between the conveying rollers 201 on the two strip guide frames 2 and on the outer side of the pretreatment box 1 adjacent to the U-shaped cleaning liquid conveying pipe 5. The two drive mechanisms 202 drive the multiple conveying rollers 201 on the two strip guide frames 2 to rotate synchronously. When the aluminum profile plate 203 is vertically inserted between the two strip guide frames 2, the conveying rollers 201 on the two strip guide frames 2 clamp the upper and lower ends of the aluminum profile plate 203, so that the aluminum profile plate 203 is conveyed when the conveying rollers 201 rotate.

[0020] Please see Figure 2 and Figure 4 Multiple atomizing nozzles 501 are fixedly connected at equal intervals on both the front and rear ends of the U-shaped cleaning fluid delivery pipe 5. A first connecting pipe 502 is fixedly connected to the middle of the upper end of the U-shaped cleaning fluid delivery pipe 5. A cleaning fluid storage tank 504 is fixedly connected to one side of the upper end face of the pretreatment box 1. The upper end of the first connecting pipe 502 extends out of the upper end face of the pretreatment box 1 and is fixedly connected to the cleaning fluid storage tank 504. A first delivery pump 503 is fixedly installed on the first connecting pipe 502. After the aluminum profile plate 203 enters through the rectangular opening 101 on one side of the pretreatment box 1, it first passes through the inside of the U-shaped cleaning fluid delivery pipe 5. The first delivery pump 503 delivers the cleaning fluid inside the cleaning fluid storage tank 504 to the U-shaped cleaning fluid delivery pipe 5, so that the cleaning fluid is evenly sprayed from the multiple atomizing nozzles 501 inside the U-shaped cleaning fluid delivery pipe 5 to the front and rear ends of the aluminum profile plate 203 to remove the grease from the front and rear ends of the aluminum profile plate 203.

[0021] Please see Figure 2 and Figure 3 Two brush rollers 3 are fixedly connected to a rotating shaft 301 in the middle. A drive device 4 is fixedly connected to the middle of the upper end face of the pretreatment box 1. Both the front and rear ends of the drive device 4 are fixedly connected to a drive motor 401. The upper ends of the two rotating shafts 301 extend into the drive device 4 and are fixedly connected to the output shafts of the two drive motors 401 respectively. The aluminum profile plate 203, after being sprayed with cleaning liquid, continues to move between the two brush rollers 3. The two drive motors 401 synchronously drive the two brush rollers 3 to rotate, so that the two brush rollers 3 brush and clean the front and rear end faces of the aluminum profile plate 203 to remove stubborn impurities.

[0022] Please see Figure 2 and Figure 5 Multiple flat nozzles 601 are fixedly connected at equal intervals on both the front and rear ends of the U-shaped clean water conveying pipe 6. A second connecting pipe 602 is fixedly connected to the middle of the upper end of the U-shaped clean water conveying pipe 6. The upper end of the second connecting pipe 602 extends out of the upper end face of the pretreatment box 1 and is fixedly connected to a second conveying pump 603. After being brushed by the brush roller 3, the aluminum profile plate 203 finally moves to the inside of the U-shaped clean water conveying pipe 6. The second conveying pump 603 conveys external clean water to the U-shaped clean water conveying pipe 6, so that the multiple flat nozzles 601 on the inside of the U-shaped clean water conveying pipe 6 pressurize and spray water onto the aluminum profile plate 203, rinsing the front and rear ends of the aluminum profile plate 203. Multiple sets of U-shaped clean water conveying pipes 6 can be set as needed to achieve thorough rinsing of the aluminum profile plate 203. After rinsing, the aluminum profile plate 203 is sent out from the rectangular opening 101 on the other side of the pretreatment box 1.

[0023] Please see Figure 6 Two brush rollers 3 are each fixedly equipped with a first U-shaped baffle 302 on their outer sides. The upper end of the first U-shaped baffle 302 is fixedly connected to the upper inner surface of the pretreatment box 1. The first U-shaped baffle 302 shields the front and rear ends of the two brush rollers 3 to prevent impurities from splashing. Two U-shaped baffles 505 are fixedly equipped with a second U-shaped baffle 505 on both the front and rear ends of the U-shaped cleaning fluid conveying pipe 5. The upper end of the second U-shaped baffle 505 is fixedly connected to the upper inner surface of the pretreatment box 1. The second U-shaped baffle 505 shields the front and rear ends of the U-shaped cleaning fluid conveying pipe 5 to prevent cleaning fluid from splashing. Three U-shaped baffles 604 are fixedly equipped with a third U-shaped baffle 604 on both the front and rear ends of the U-shaped clean water conveying pipe 6. The upper end of the third U-shaped baffle 604 is fixedly connected to the upper inner surface of the pretreatment box 1. The third U-shaped baffle 604 shields the front and rear ends of the U-shaped clean water conveying pipe 6 to prevent rinsing water from splashing.

[0024] Working principle: During use, the aluminum profile plate 203 to be processed is vertically inserted into the conveying channel between the upper and lower strip guide frames 2. The drive mechanism 202 synchronously drives all the conveying rollers 201 to rotate, and pushes the aluminum profile plate 203 forward through friction, so that the aluminum profile plate 203 enters from the rectangular opening 101 on one side of the pretreatment box 1. When passing through the U-shaped cleaning liquid conveying pipe 5, the first conveying pump 503 sprays the cleaning liquid in the cleaning liquid storage tank 504 evenly onto the surface of the aluminum profile through the atomizing nozzle 501 to complete the initial decomposition of grease; then the aluminum profile enters the double brush roller 3 station, where the rotating brush driven by the drive motor 401 mechanically brushes the surface to thoroughly remove stubborn oil stains and oxide layers; finally, it is rinsed multiple times with clean water through the high-pressure flat nozzle 601 of the U-shaped clean water conveying pipe 6 to ensure that there are no chemical residues on the surface. The entire process is prevented from liquid splashing by the first U-shaped baffle 302, the second U-shaped baffle 505 and the third U-shaped baffle 604. The finished aluminum profile is output from the rectangular opening 101 on the other side, realizing the fully automated pretreatment of degreasing-brushing-rinsing, providing a clean surface for subsequent anodizing or spraying processes.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
