[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] like Figures 1 to 5As shown, the fully automatic transfer system for aluminum plate roller coating and printing in this embodiment includes a first conveyor line 1 and a drying box 10 installed on one side of the first conveyor line 1. One side of the first conveyor line 1 is connected to the roller coating production line and directly conveys the roller-coated aluminum plates in a directional manner. The drying box 10 is actually a device for drying and curing the roller-coated aluminum plates. In the prior art, because the roller-coated aluminum plates are conveyed forward piece by piece, the conveyor line is often set to be very long in order to increase the curing effect. This makes the drying box 10 also very long, thereby increasing the equipment cost. The drying box 10 has openings on both the left and right sides as channels for the aluminum plates to enter and exit, and a heating plate 2 is installed inside the drying box 10. 6. Several heating plates 26 are arranged on the top and bottom to avoid uneven heating or low temperature affecting the simultaneous drying of multiple aluminum plates. A feeding rack 2 is installed at the top of the first conveyor line 1 to feed aluminum plates one by one. A lifting cylinder 3 is installed on the inner top of the feeding rack 2. At least two sets of lifting cylinders 3 are provided and need to be connected to an external pneumatic control system. A platform 13 is installed at the bottom of the lifting cylinder 3. A controllable suction cup 14 is installed at the bottom of the platform 13. The controllable suction cup 14 is connected to a suction component to adsorb the surface of the aluminum plate. The platform 13 is controlled to move up and down by all the lifting cylinders 3. A lifting and pushing mechanism is installed on the platform 13.

[0029] The bottom of the drying chamber 10 is equipped with a built-in roller assembly 24, which requires a dedicated power motor to control the rotation of the rollers and the feeding speed of the components. A transfer frame 22 is placed on top of the built-in roller assembly 24. The transfer frame 22 is quite long, often exceeding the combined length of two aluminum plates. A lifting ring 21 is installed at the top of the transfer frame 22, which can be tied to ropes of external lifting equipment. This allows for the transfer of large quantities of aluminum plates after drying without further roller coating, enabling the transfer system to be more flexible. Inside the transfer frame 22, several inclined roller frames 20 are arranged at an angle. These rollers slope downwards from the direction away from the platform 13. Thus, after the aluminum plates enter the transfer frame 22, they are supported by their own weight and move along the inclined roller frames 20. During the feeding operation, an elastic buckle 23 is installed at the middle position of the surface of the inclined roller frame 20. It should be noted that the elastic buckle 23 itself contains a spring, and a buckle is set on the top side, while a curved surface is set on the side near the entrance of the transfer frame 22, which can directly contact the aluminum plate conveyed from top to bottom and be squeezed downward by the aluminum plate. After the aluminum plate passes and is limited, one end of the aluminum plate is limited by the buckle. After the buckle is tightened, the elastic buckle 23 no longer deforms after the aluminum plate behind it comes into contact with it. This separates the first aluminum plate from the aluminum plate behind it by the elastic buckle 23, which is conducive to the vertical flow of hot air during the heating and curing operation of the aluminum plate and promotes uniform heating. A discharge control mechanism is set at one end of the transfer frame 22 near the lowest position of the inclined roller frame 20, which can simultaneously discharge multiple aluminum plates accumulated inside the inclined roller frame 20.

[0030] Specifically, the lifting and pushing mechanism includes side plate 4, drive component, adjusting push rod 16, extension push rod 15, and assembly table 17. Side plate 4 is installed on both sides of the frame 13, and the side plate 4 is located on the front and rear end faces of the frame 13, so that the side plate 4 and the frame 13 form a U-shaped structure. Adjusting push rods 16 are installed vertically on the surface of the side plate 4. The adjusting push rod 16 is a conventional telescopic cylinder, which can move vertically. The bottom end of the adjusting push rod 16 is equipped with the assembly table 17 for use as an assembly component. The surface of the assembly table 17 is connected horizontally by the extension push rod 15. The extension push rod 15 itself is adjusted vertically with the assembly table 17, and its extension direction is horizontal. The end of the extension push rod 15 is equipped with the drive component.

[0031] Furthermore, the driving components include a servo motor 19 and a push roller 18. The servo motor 19 is mounted at the end of the extension push rod 15. The servo motor 19 itself is a miniaturized motor equipped with a forward and reverse rotation control circuit. It is powered by an external power source and generates rotational torque. The push roller 18 is mounted on the output shaft of the servo motor 19, and the surface of the push roller 18 is fitted with an anti-slip sleeve. In actual production, after the controllable suction cup 14 adsorbs the aluminum plate, in order to directionally push the aluminum plate, the adjustment push rod 16 needs to be activated to extend downwards, thereby causing the assembly table 1 to... 7. The push roller 18 moves downward, and then the extension push rod 15 is activated so that the push roller 18 is below the aluminum plate. After the controllable suction cup 14 is released, the aluminum plate falls on the multiple push rollers 18. At this time, the servo motor 19 is activated to push the aluminum plate forward to realize the feeding and transfer operation. In order to ensure that the entire transfer system is fully automated, a laser-type component for aluminum plate sensing needs to be installed under the frame 13, and a controller is configured. Then, when the aluminum plate below is detected, the aluminum plate is transferred up and down or even forward and backward with the help of the controller programming.

[0032] Furthermore, the unloading control mechanism includes an adjusting component, a guide groove 31, a shifting rod 28, and a limiting plate 33. One end of the transfer frame 22 near the lowest position of the inclined roller frame 20 is provided with a guide groove 31 arranged horizontally, which is actually arranged in the unloading direction near the transfer frame 22. The guide groove 31 extends vertically and has a relatively large actual length. The shifting rod 28 is installed inside the guide groove 31 for limiting. The side of the shifting rod 28 is limited inside the guide groove 31. An adjusting component is installed at the top of the shifting rod 28 to adjust the actual height of the shifting rod 28. Several limiting plates 33 are installed between two shifting rods 28. Under normal circumstances, the limiting plates 33 are in front of the lowest position of the inclined roller frame 20, which can limit and block the aluminum plate on the inclined roller frame 20 from the front to prevent it from overstepping.

[0033] Furthermore, the adjusting components include a screw assembly 29 and a lifting screw 30. The screw assembly 29 is fixedly installed on the surface of the transfer frame 22 above the shift rod 28 and has a threaded hole structure with vertical conduction. The lifting screw 30 is threaded inside the screw assembly 29. The lifting screw 30 is arranged vertically, and the top surface area of ​​the lifting screw 30 is relatively large, so a handle can be provided to facilitate manual rotation of the lifting screw 30. The bottom end of the lifting screw 30 is connected to the top bearing of the shift rod 28. Thus, when the lifting screw 30 rotates, the reverse force of the thread causes the lifting screw 30 and even the shift rod 28 below it to move upward, thereby causing the limiting plate 33 to rise upward. The lowest position of the inclined roller frame 20 is unconstrained, thus enabling uniform inclined material operation.

[0034] Furthermore, sliders 32 are installed on both sides of the transfer frame 22. The sliders 32 are arranged laterally. The inner sidewall of the drying chamber 10 outside the transfer frame 22 is equipped with sliding grooves. The sliding grooves are concave groove structures arranged on the left and right. The sliders 32 can be inserted into the sliding grooves, thereby limiting the movement of the entire transfer frame 22 laterally. When the built-in roller group 24 pushes the transfer frame 22 to move back and forth, the movement of the transfer frame 22 can be limited by the limiting effect of the sliders 32 and the sliding grooves.

[0035] Furthermore, a hot air blower 7 is installed at the top of the drying chamber 10. The hot air blower 7 itself has a heater and an air pump. A collection pipe 8 is installed at the input end of the hot air blower 7. The collection pipe 8 is in the form of a pipe array with multiple inlets, which act on different positions and heights inside the drying chamber 10. It can draw in and uniformly process hot air at different positions and heights in the drying chamber 10. A return pipe 6 is installed at the output end of the hot air blower 7. The return pipe 6 returns the drawn and reheated hot air.

[0036] Furthermore, the top of the inner wall of the drying oven 10 is provided with an internal groove 27. The internal groove 27 is recessed and has a large space. An air jet frame 25 is installed inside the internal groove 27. The top of the air jet frame 25 is connected to the return pipe 6, which can receive heated hot air and spray it downward. During the whole process, the hot air circulates in both the upper and lower directions, so that the air temperature inside the drying oven 10 is relatively uniform, avoiding the problem of poor drying effect. In addition, exhaust components 9 are installed on the top of the drying oven 10 on both sides of the hot air blower 7. The main body of the exhaust component 9 is a pipe, and a switch valve is configured inside. When opened, it can exhaust the humid air inside the drying oven 10 to the outside.

[0037] Furthermore, a second conveyor line 12 is installed on the surface of the drying chamber 10 away from the first conveyor line 1. The rollers on it are also equipped with dedicated drive components to avoid sharing a set of drive components with the built-in roller group 24. This allows for the directional conveying of the aluminum plate after roller coating and drying. Protective door panels 5 are installed at both the left and right openings of the drying chamber 10. The two sides of the protective door panels 5 are limited by the limiting grooves at the left and right openings of the drying chamber 10. The limiting grooves have openings at the top, and an opening and closing cylinder 11 is installed at the bottom of the protective door panel 5. The opening and closing cylinder 11 is installed on the outside of the drying chamber 10. While not affecting the conveying of the aluminum plate, the opening and closing cylinder 11 itself is large and can be raised or lowered to close or open the entire drying chamber 10. When closed, it can ensure that the internal temperature of the drying chamber 10 is high, improving the drying efficiency. This is different from the existing technology with open sides, resulting in higher overall drying efficiency.

[0038] It should be noted that, in order to improve drying efficiency, it is not necessary to wait until the entire transfer rack 22 is filled before the drying operation. Instead, one aluminum plate can be placed on the single-layer inclined roller rack 20 first. After both the upper and lower layers are filled, the transfer rack 22 for that part is first moved into the drying chamber 10 by the built-in roller group 24 for priority drying. After the other aluminum plate is placed on the single layer, the transfer rack 22 is fully pushed into the drying chamber 10. When unloading, the aluminum plate that was dried first can be taken out of the drying chamber 10 first. While the aluminum plate of that part is slowly cooled, the other part is still in the process of heating and curing. Thus, the drying and curing operation of the entire aluminum plate roller coating process is very flexible, and the actual length of the drying chamber 10 used is also smaller, which can save on actual equipment costs.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
