Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and specifically to an aluminum profile processing spraying equipment. Background Technology

[0002] Aluminum profile spraying is a process of applying a coating to the surface of aluminum profiles. Its main purpose is to enhance the aesthetics, corrosion resistance, and functionality of the aluminum profiles. The spraying process mainly uses the spray nozzles in the spraying equipment to apply the coating to the surface of the aluminum profiles.

[0003] For example, the prior art application number CN202223542534.6 discloses an aluminum profile spraying equipment, including a housing, an angle adjustment mechanism fixedly connected to the outside of the housing, a spraying head movably connected to the outside of the housing, a waste bin movably connected to the outside of the housing, and a limit mechanism fixedly connected to the outside of the angle adjustment mechanism.

[0004] The aforementioned prior art, as learned through actual use, mainly involves spraying the aluminum profile with a spray head located at the top of the aluminum profile, and then spraying the other side of the aluminum profile by rotating it. The rotation of the aluminum profile not only causes minor damage to the initially formed coating, affecting the adhesion of the paint and causing uneven flow, but also increases the process flow and slows down the spraying efficiency. Utility Model Content

[0005] To address the aforementioned problems, this utility model aims to provide an aluminum profile processing and spraying equipment.

[0006] To achieve this technical objective, the present invention provides an aluminum profile processing and spraying equipment, comprising a housing and a glass plate rotatably mounted on the front side of the housing. At least two clamping blocks are provided inside the housing for clamping the aluminum profile against both sides. A feeding component is provided at the upper end of the housing. Nozzles are provided on the top and bottom walls of the housing. A heating element is provided on one side of each clamping block. The heating element includes an infrared heating lamp and an electric heating plate. Infrared heating lamps are provided at the upper and lower ends of each clamping block, with the radiating ends of the infrared heating lamps facing the upper and lower surfaces of the aluminum profile, respectively. One side of each clamping block is pressed against the electric heating plate.

[0007] Preferably, each of the left and right walls of the housing is fixed with a first electric telescopic rod via a connecting frame, and the output end of each first electric telescopic rod is fixed to one side of the clamping block for driving the clamping block to move.

[0008] Preferably, the top and bottom walls of the housing are each fixed with a second electric telescopic rod via a connecting frame. The output end of each second electric telescopic rod is fixed with a frame via a horizontal plate, and an ultrasonic sensor is fixed to the inner side of the horizontal plate via bolts. The inner side of the frame is fixed to the nozzle.

[0009] Preferably, the feeding component includes a material box, a liquid pump, and a hose. The lower surface of the material box is fixed to the upper end of the box body. The liquid pump is installed inside the material box, and the output end of the liquid pump is connected to a nozzle through a hose.

[0010] Preferably, each of the clamping blocks has a mounting bracket fixed to one side by bolts, and infrared heating lamps are fixed to the upper and lower surfaces of the mounting bracket.

[0011] Preferably, one side of the mounting bracket is fixed with an electric heating plate by bolts, and the inner side of the electric heating plate abuts against the outer side of the clamping block;

[0012] This utility model employs nozzles simultaneously installed at the upper and lower ends of the aluminum profile, which increases the efficiency of spraying the aluminum profile while ensuring that the aluminum profile does not rotate.

[0013] Furthermore, when the aluminum profile is clamped by the clamping block, the infrared heating lamps and electric heating plates in the heating element are activated, which can simultaneously heat the aluminum profile itself and the coatings on the upper and lower surfaces. During this process, the coating and the aluminum profile can interact better, and the coating can better conform to the microstructure of the aluminum profile surface, which can enhance the adhesion. At the same time, simultaneous heating inside and outside reduces the temperature gradient caused by heating the coating on one side, allowing the solvents and other components in the coating to evaporate evenly, avoiding local over-drying or over-wetting. This helps to form a coating with uniform thickness and better quality, making the coating surface smoother and preventing coating drips. Attached Figure Description

[0021] like Figures 1 to 4 As shown, this embodiment of the invention provides an aluminum profile processing and spraying equipment, including a housing 1 and a glass plate 6 rotatably disposed on the front side of the housing 1. At least two clamping blocks 2 are disposed inside the housing 1 for clamping the aluminum profile 7 on both sides. A feeding component 5 is disposed at the upper end of the housing 1. 8-16 nozzles 3 are disposed on the top and bottom walls of the housing 1. A heating element 4 is disposed on one side of each clamping block 2. The heating element 4 includes an infrared heating lamp 42 and an electric heating plate 43. An infrared heating lamp 42 is disposed at the upper and lower ends of each clamping block 2, and the radiating ends of the infrared heating lamps 42 are respectively facing the upper and lower surfaces of the aluminum profile 7. One side of each clamping block 2 is pressed against the electric heating plate 43 for heat conduction to the aluminum profile 7.

[0022] refer to Figure 1 and Figure 2 The left and right walls of the housing 1 are each fixed with a first electric telescopic rod 8 via a connecting frame. The output end of each first electric telescopic rod 8 is fixed to one side of the clamping block 2 to drive the clamping block 2 to move. The top and bottom walls of the housing 1 are each fixed with a second electric telescopic rod 9 via a connecting frame. The output end of each second electric telescopic rod 9 is fixed to a frame 10 via a horizontal plate, and an ultrasonic sensor 11 is fixed to the inner side of the horizontal plate by bolts. The inner side of the frame 10 is fixed to the nozzle 3. The feeding component 5 includes a material box 12, a liquid pump 13, and a hose 14. The lower surface of the material box 12 is fixed to the upper end of the housing 1. The liquid pump 13 is installed inside the material box 12, and the output end of the liquid pump 13 is connected to the nozzle 3 via the hose 14 to feed the nozzle 3.

[0023] refer to Figure 4Each clamping block 2 has a mounting bracket 41 fixed to one side by bolts. Infrared heating lamps 42 are fixed to the upper and lower surfaces of the mounting bracket 41, allowing simultaneous heating of the coating on both the upper and lower surfaces of the aluminum profile 7. An electric heating plate 43 is fixed to one side of the mounting bracket 41 by bolts, with the inner side of the electric heating plate 43 abutting against the outer side of the clamping block 2. The temperature of the aluminum profile 7 itself is typically between 80-200℃. For simple drying purposes such as removing moisture, the temperature can be set around 80-120℃. For curing special coatings, such as high-temperature curing powder coatings, the temperature of the aluminum profile 7 may need to reach 180-200℃. The heating temperature of the coating also varies depending on the coating material. For water-based coatings, the temperature is generally 60-100℃ to promote moisture evaporation and initial curing of the coating. For solvent-based coatings, the temperature may be 80-150℃, a range that facilitates solvent evaporation and cross-linking curing of the coating. For powder coatings, the coating temperature usually needs to reach 160-200℃ to ensure that the powder is completely melted, leveled and cured.

[0024] Working principle: After the aluminum profile 7 is placed between the two clamping blocks 2, the movement of the two clamping blocks 2 can be controlled by activating the first electric telescopic rod 8, thereby changing the distance between the two clamping blocks 2. This allows for clamping and fixing of aluminum profiles 7 of different widths, increasing the adaptability of the aluminum profile 7.

[0025] After the aluminum profile 7 is clamped, the liquid pump 13 is activated to supply material to the nozzle 3, which sprays the coating onto the upper and lower surfaces of the aluminum profile 7. After spraying, the ultrasonic sensor 11 detects the coating thickness. When the ultrasonic sensor 11 detects that the coating thickness at a certain location on the aluminum profile 7 is less than the target thickness, the control system sends a command to the second electric telescopic rod 9 to extend it, bringing the nozzle 3 closer to the surface of the aluminum profile 7 and increasing the amount of coating sprayed per unit time, thereby thickening the coating. Conversely, when the ultrasonic sensor 11 detects that the coating thickness is greater than the target thickness, the control system retracts the second electric telescopic rod 9, moving the nozzle 3 away from the surface of the aluminum profile 7 and reducing the amount of coating sprayed per unit time, making the coating thinner and thus achieving more uniform coating of the aluminum profile 7.

[0026] When the aluminum profile 7 is clamped by the clamping block 2, the infrared heating lamp 42 and the electric heating plate 43 can be activated. The heat generated by the infrared heating lamp 42 will evenly heat the upper and lower ends of the aluminum profile 7, while the electric heating plate 43 conducts heat to the aluminum profile 7 itself, achieving simultaneous heating of the aluminum profile 7 itself and the coatings on the upper and lower surfaces. The aluminum profile 7 expands due to heating, and the heating of the external coating promotes the drying and shrinkage of the coating. In this process, the coating and the aluminum profile 7 can interact better, and the coating can better fit the microstructure of the surface of the aluminum profile 7, just like "embedding" the coating into the aluminum profile 7, which can enhance the adhesion. At the same time, the simultaneous heating inside and outside reduces the temperature gradient caused by the coating being heated on one side, allowing the solvent and other components in the coating to evaporate evenly, avoiding local over-drying or over-wetting. This helps to form a coating with uniform thickness and better quality, making the coating surface smoother. In addition, it can accelerate the drying speed of the coating and avoid coating dripping.

Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
