Description

Technical Field

[0001] This utility model relates to the field of roller coating machine technology, specifically to a uniform heating mechanism for an aluminum plate roller coating machine. Background Technology

[0002] Roller coating machines are an important type of equipment in the coating equipment series. They are characterized by low paint loss, high production efficiency, and simple and convenient maintenance, and can be well integrated with production lines. After the roller coating process is completed, the coated parts need to be heated and dried. Direct drying after roller coating can avoid damage to the coating on the parts.

[0003] However, existing roller coating machines, due to their simple structure, cannot achieve uniform heating and drying of aluminum sheet workpieces during heating and drying. This results in inconsistent workpiece quality, reducing overall production quality and efficiency, and causing significant inconvenience to operators. Therefore, we propose a uniform heating mechanism for aluminum sheet roller coating machines. Utility Model Content

[0004] In view of the shortcomings of existing roller coating machines in heating and drying aluminum sheet workpieces, which are simple in structure and cannot achieve uniform heating and drying, resulting in inconsistent quality of aluminum sheet workpieces, this utility model provides a uniform heating mechanism for an aluminum sheet roller coating machine. It has the advantages of effectively achieving uniform heating and drying of the surface of the processed parts, thereby improving the quality of workpiece processing and increasing the processing efficiency of the device, thus solving the problems mentioned in the background art.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 5 This utility model provides a technical solution: a uniform heating mechanism for an aluminum plate roller coating machine, including a mounting frame 9 set on the top of a workbench 1, and a roller coating mechanism 5 connected to the workbench 1 on one side of the mounting frame 9. A mounting frame 17 is set inside the mounting frame 9, and heating wires 15 arranged in an S-shape are connected to the bottom of the mounting frame 17. A retainer 18 for limiting the heating wires 15 is tightly fixed to the bottom of the mounting frame 17, and a temperature sensor 19 is connected to the top of the mounting frame 17. Figure 4 , 5 As shown, the temperature sensor 19 can monitor the temperature at the mounting frame 17 in real time, preventing damage to the workpiece due to excessive temperature. At the same time, the temperature sensor 19 can detect temperature changes to achieve uniform heating. The mounting bracket 8 allows workers to easily install and remove the heating wire 15, improving the practicality of the device.

[0023] like Figure 4 , 5As shown, side plates 20 are fixedly connected to both ends of the mounting frame 17. Threaded rods 14 are threaded onto the side plates 20, and threaded tubes 21 are tightly fastened to the side plates 20. The threaded rods 14 are connected to the threaded tubes 21. The top of the threaded rods 14 is rotatably connected to and through the mounting frame 9. The top of the threaded rods 14 is fastened to the second motor 8, and the bottom of the threaded rods 14 is connected to the inner wall of the mounting frame 9 through the connecting seat 13. The rotation of the second motor 8 drives the mounting frame 17 to adjust its height. This allows for adjustment of the distance between the heating wire 15 and the workpiece when processing workpieces of different thicknesses, thus avoiding poor drying results due to excessive height or low height. In addition, to improve the stability of the height adjustment of the mounting frame 17, vertical rods 16 are vertically connected to the four corners of the top of the mounting frame 17. Sleeves 12 are connected to the corresponding positions on the bottom of the mounting frame 9. The tops of the vertical rods 16 are coaxially sleeved inside the sleeves 12. When the mounting frame 17 is adjusted in height, it drives the vertical rods 16 to slide within the sleeves 12. This design is not only simple and easy to adjust but also highly practical.

[0024] like Figure 2 , 3 As shown, an opening 22 is provided at the top of the mounting frame 9, and a filter screen 23 is fixedly connected inside the opening 22 to prevent external impurities from blowing onto the surface of the workpiece and causing contamination, thus ensuring the processing quality and yield. A fan 7 is connected to the top of the opening. Multiple ventilation openings 3 are opened on the side wall of the mounting frame 9, and end plates 10 are connected to both sides of the mounting frame 9. A cavity for placing the mounting frame 17 is formed between the two end plates 10 and the mounting frame 9. The fan 7 blows air onto the top of the mounting frame 17, and the heating wire 15 works at the same time to generate hot air. Under the action of the end plates 10 and the ventilation openings 3, the hot air can be driven to circulate in the cavity. Figure 3 The flow indicated by the middle arrow allows the workpiece surface to receive hot air evenly, achieving uniform heating and drying of the workpiece.

[0025] In summary, the uniform heating mechanism of this aluminum plate roller coating machine has a through groove 6 on the top of the workbench 1. A conveyor belt 2 driven by a first motor 4 is connected to the through groove 6. A control box 11 is set on the workbench 1, and a controller is connected to the control box 11. The first motor 4, the roller coating mechanism 5, the temperature sensor 19, the fan 7, and the second motor 8 are connected to the controller. The workpiece is placed on the top of the workbench 1 and transported to the roller coating mechanism 5 by the conveyor belt 2 for roller coating. After the roller coating is completed, it is transported to the bottom of the mounting frame 9. Under the control of the fan 7, the heating wire 15, and the temperature sensor 19, hot air can be uniformly delivered to the surface of the workpiece and discharged through the vent 3. This can effectively achieve uniform heating and drying of the surface of the workpiece, thereby improving the quality of workpiece processing and increasing the processing efficiency of the device.
