Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel packaging, and in particular to a film coating device for aluminum single-panel packaging. Background Technology

[0002] Aluminum single-layer panels are building decoration materials with aluminum alloy sheets as the base material. After processing, aluminum single-layer panels are coated with fluorocarbon paint to increase their durability and corrosion resistance, while also providing a certain decorative effect. However, because the paint is fragile and easily scratched during transportation, aluminum single-layer panels need to be laminated before packaging to protect the surface coating. However, existing aluminum single-layer panel laminating equipment usually does not have the function of cleaning the surface of the aluminum single-layer panels. Therefore, if dust adheres to the surface of the aluminum single-layer panels, it will affect the laminating effect. Thus, a laminating device for aluminum single-layer panel packaging is needed to solve the problem of not being able to clean the dust on the surface of the aluminum single-layer panels before laminating.

[0003] Chinese Patent Publication No. CN219903358U discloses an aluminum single-panel coating device, including a coating box. A conveyor belt is interlaced on the lower surface of the coating box, and aluminum single panels are conveyed on the conveyor belt. In this utility model, by setting a cleaning device, two sets of clamping plates, and a second cylinder, when the limiting rod below the cleaning device detects the aluminum single panel through a pressure sensor, the two second cylinders are activated to extend and push the corresponding clamping plates to move towards each other, thus centering and clamping the aluminum single panel. Then, the first cylinder of the cleaning device is activated to extend and drive the cleaning disc to move downward. Then, the first motor is activated to drive the cleaning disc to rotate, so that the brushes formed by multiple arc bands on the cleaning disc clean the coated surface of the aluminum single panel. Compared with the existing cleaning mechanism for aluminum single panel coating, this device integrates aluminum single panel clamping, centering positioning, and surface cleaning, which facilitates accurate coating of aluminum single panels and helps to shorten the coating time, thereby improving the coating efficiency of aluminum single panels.

[0004] Although the aforementioned patent describes a method to clean the surface of aluminum panels using a brush on a cleaning disc, the rotation of the brush and the downward pressure of the first cylinder can scratch the coating on the aluminum panel surface. Furthermore, static electricity is generated when the brush rubs against the aluminum panel, causing dust to re-adhere to the surface of the aluminum panel after cleaning, affecting the subsequent coating effect. In addition, the device cannot press and fix the aluminum panel during the conveying process, which can easily cause the aluminum panel to shift during conveying, thus affecting the subsequent coating effect. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this device provides a film-coating device for aluminum single-panel packaging. While cleaning the aluminum single-panel, the device can eliminate the static electricity on the surface of the aluminum single-panel, preventing dust from being re-adsorbed on the surface of the aluminum single-panel due to static electricity in subsequent operations. At the same time, the device can press the aluminum single-panel during film coating to improve the film coating effect.

[0006] The purpose of this utility model is to provide a laminating device for aluminum single-panel packaging, including a laminating machine body, conveying grooves on the left and right sides of the laminating machine body, a conveyor belt installed at the bottom of the conveying grooves, pressing mechanisms connected to the front and rear ends of the laminating machine body respectively, the bottom end of the pressing mechanism contacting the upper surface of the conveyor belt, an electrostatic dust collector, a cutting mechanism and a laminating mechanism connected sequentially from front to back in the conveying grooves, the electrostatic dust collector is used to clean the dust on the surface of the aluminum single-panel, the cutting mechanism is used to cut the film, the laminating mechanism is used to heat and cover the film onto the surface of the aluminum single-panel, and a control panel is fixedly installed on one side of the laminating machine body.

[0007] Furthermore, the pressing mechanism includes a pressing roller, with connecting rods rotatably connected to both sides of the pressing roller. The other end of the connecting rod is hinged to the front surface of the laminating machine body. An inclined tension spring is fixedly connected to the bottom of the connecting rod, and the other end of the tension spring is fixedly connected to the upper surface of the conveyor belt.

The take-up roller and the unwind roller are rotatably connected to the top of the laminating machine body, and the unwind roller is located at the front end of the take-up roller. The heating roller and the guide roller are rotatably connected in the conveying groove, and the heating roller is located at the front end of the guide roller. A drive motor is fixedly connected to one side of the laminating machine body, and the output end of the drive motor is connected to one end of the take-up roller.

[0014] 1.

[0021] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0022] according to Figures 1 to 4As shown, a laminating device for aluminum single-panel packaging includes a laminating machine body 1. Conveying troughs are provided on the left and right sides of the laminating machine body 1, and a conveyor belt 2 is installed at the bottom of the conveying troughs. Pressing mechanisms 3 are connected to the front and rear ends of the laminating machine body 1, respectively. The bottom end of the pressing mechanism 3 contacts the upper surface of the conveyor belt 2. An electrostatic dust collector 5, a cutting mechanism 7, and a laminating mechanism 6 are connected sequentially from front to back within the conveying troughs. The electrostatic dust collector 5 is used to clean dust from the surface of the aluminum single-panel. The laminating mechanism 6 is used to heat and coat the film onto the surface of the aluminum single-panel. The cutting mechanism 7 is used to cut the film. A compaction mechanism is fixedly connected to the top of the conveying troughs, located between the laminating mechanisms 6. A control panel 4 is fixedly installed on one side of the laminating machine body 1.

[0023] In practical implementation, a conveyor trough is opened through both the front and rear ends of the laminating machine body 1. A conveyor belt 2 is installed at the bottom of the conveyor trough to convey aluminum panels. Two electrostatic precipitators 5 are fixedly connected between the two side walls at the front end of the conveyor trough. The electrostatic precipitators 5 can be SJ-H. This series of electrostatic precipitators 5 not only eliminates static electricity on the surface of aluminum panels, but also blows away dust adhering to the surface of the aluminum panels, improving the cleanliness of the aluminum panel surface and enhancing the dust removal and cleaning effect. The inlet and outlet ends of the conveyor trough are respectively equipped with pressing mechanisms 3. Pressing mechanisms 3 are used to press the aluminum panels downwards, increasing the friction between the lower surface of the aluminum panel and the upper surface of the conveyor belt 2, preventing the aluminum panels from slipping or shifting during conveyor belt 2 transport, increasing the stability of aluminum panel transport, and improving the accuracy of aluminum panel lamination. The cutting mechanism 7 can cut the film after the aluminum panel is laminated. The compaction mechanism can press the film downwards onto the upper surface of the aluminum panel, enhancing the lamination effect. The control panel 4 is equipped with a PLC board, which can be used to start and stop the lamination mechanism 6 and the cutting mechanism 7.

[0024] Furthermore, the pressing mechanism 3 includes a pressing roller 31, with connecting rods 32 rotatably connected to both sides of the pressing roller 31. The other end of the connecting rods 32 is hinged to the front surface of the laminating machine body 1. An inclined tension spring 33 is fixedly connected to the bottom of the connecting rods 32, and the other end of the tension spring 33 is fixedly connected to the upper surface of the conveyor belt 2.

[0025] In practical implementation, one end of the connecting rod 32 is hinged to the side wall of the laminating machine body 1, and the other end of the connecting rod 32 is hinged to the pressing roller 31. At the same time, since one end of the tension spring 33 is fixedly connected to the bottom of the connecting rod 32 and the other end is fixedly connected to the upper surface of the conveyor belt 2, the tension of the tension spring 33 makes the end of the connecting rod 32 near the pressing roller 31 always rotate downward with the other end as the center. When the connecting rod 32 rotates downward with the tension of the tension spring 33, the pressing roller 31 can be tightly attached to the surface of the conveyor belt 2. When the aluminum single panel is placed between the conveyor belt 2 and the pressing roller 31, the downward pressure of the pressing roller 31 can increase the pressure of the aluminum single panel on the conveyor belt 2, thereby increasing the friction between the lower surface of the aluminum single panel and the conveyor belt 2, and increasing the stability of the aluminum single panel conveying. At the same time, the tension spring 33 can be used to press the pressing roller 31 on aluminum single panels of different thicknesses, improving the pressing effect of the device on aluminum single panels of different thicknesses.

[0026] Furthermore, the laminating mechanism 6 includes a take-up roller 61, an unwind roller 62, a heating roller 63, and a guide roller 64. The take-up roller 61 and the unwind roller 62 are rotatably connected to the top of the laminating machine body 1, and the unwind roller 62 is located at the front end of the take-up roller 61. The heating roller 63 and the guide roller 64 are rotatably connected to the conveying groove, and the heating roller 63 is located at the front end of the guide roller 64. A drive motor 65 is fixedly connected to one side of the laminating machine body 1, and the output end of the drive motor 65 is connected to one end of the take-up roller 61.

[0027] In practice, the surface of the unwinding roller 62 is wound with a film-coated roll, and the other end of the film-coated roll is guided by the heating roller 63 and the guide roller 64 in sequence and finally wound onto the surface of the take-up roller 61. The top of the conveying groove has two square holes for the film to pass through. The drive motor 65 controls the rotation of the take-up roller 61 to unfold the film wound on the surface of the unwinding roller 62. At the same time, the surface of the heating roller 63 is provided with heating wires, and the heating of the film by the heating roller 63 causes the film to adhere to the surface of the aluminum panel.

[0028] Furthermore, the outlet end of the electrostatic precipitator 5 is positioned facing the conveyor belt 2, and the electrostatic precipitator 5 is fixedly connected at an angle inside the conveyor trough.

[0029] In practice, the electrostatic precipitator 5 is installed at an angle in the conveying trough. The angled electrostatic precipitator 5 can not only eliminate static electricity on the surface of the aluminum panel, but also blow the dust out of the conveying trough to avoid dust entering the subsequent coating process and causing coating failure.

[0030] Furthermore, the cutting mechanism 7 includes an electric push rod 71, which is fixedly connected to the top of the conveying trough. The electric push rod 71 is located between the heating roller 63 and the guide roller 64, and a loop frame 72 is fixedly connected to the bottom of the electric push rod 71.

[0031] In practice, the size of the loop frame 72 and the gears are matched with the size of the aluminum panel. After the electric push rod 71 controls the loop frame 72 to move downward, the inner side of the loop frame 72 abuts against the perimeter of the aluminum panel. The film is cut by the pressure between the loop frame 72 and the outer surface of the aluminum panel.

[0032] Furthermore, a position sensor 8 and a counting sensor 9 are fixedly connected to the top of the conveying trough, and the position sensor and the counting sensor are electrically connected to the control panel.

[0033] In specific implementation, position sensor 8 is located at the front end of heating roller 63 in the conveying trough. When position sensor 8 can sense aluminum single panel, it sends a signal to control screen 4, causing control screen 4 to control drive motor 65 to run and realize film conveying. At the same time, it can cause electric push rod 71 to control the loop frame 72 to move downward to realize the punching and cutting of film. Counting sensor 9 is located at the top of the discharge end of conveying trough. Every time counting sensor 9 senses aluminum single panel, it counts the quantity once, realizing the calculation of the number of aluminum single panel films.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
