Description

Technical Field

[0001] The utility model relates to the technical field of aluminum single plate production, in particular to a coating device for aluminum single plate production. Background Art

[0002] Aluminum veneer refers to a building decoration material that is processed through chroming and other treatments and then fluorocarbon spraying technology. It is resistant to acid rain, salt spray and various air pollutants, has excellent resistance to cold and heat, can withstand strong ultraviolet rays, can remain non-fading and non-powdering for a long time, and has a long service life. When processing aluminum veneer, it is necessary to use a laminating device to plasticize its surface.

[0003] As disclosed in Chinese patent announcement No. CN213108215U, a coating device for aluminum veneer production is disclosed. When in use, the transmission roller on the frame drives the upper aluminum veneer to enter the interior of the shell, and the first motor is started. The output shaft of the first motor drives the cleaning roller between the first mounting frame to rotate rapidly through the first belt, and the outside of the cleaning roller is provided with soft bristles. When it contacts the aluminum veneer, it can remove dust and impurities attached to the surface. At the same time, the fan is started, and the fan blows strong wind toward the surface of the aluminum veneer at the lower end, and cooperates with the cleaning roller to further remove dust and impurities on the surface. The cleaned aluminum veneer is further transported by the transmission roller and enters the lower end of the preheating roller. Since the sleeve rod of the preheating roller is a movable structure, when the aluminum veneer contacts the lower end of the preheating roller, the preheating roller is pressed under the action of the extrusion force. The roller rotates, so that the extrusion sleeve extends toward the upper end. When the preheating roller is completely located at the upper end of the aluminum veneer, the spring is reset to make the preheating roller squeeze the aluminum veneer. This structure can fit closely with the plate under the premise of self-adjustment according to the thickness of the plate. At this time, the electric heating wire inside the preheating roller is energized to convert electrical energy into thermal energy. In the process of contact with the aluminum veneer, its surface is heated up, thereby achieving the effect of preheating. The aluminum veneer and the film are compounded at the lower end of the lamination, and the electric push rod is started to drive the second mounting frame to move downward, so that the pressing roller is tightly pressed on the top of the aluminum veneer and the film. At the same time, the second motor is started. The output shaft of the second motor is driven by the second belt to make the pressing roller and the transmission roller rotate synchronously. In the process of film lamination, the bubbles between the two are filtered out, thereby ensuring the overall lamination effect.

[0004] However, the coating device for aluminum veneer production in the above application removes dust and impurities through a cleaning roller and blows away with strong wind, but the dust is still inside the shell and will still adhere to the surface of the aluminum veneer after flying. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a coating device for producing aluminum veneer. Utility Model Content

[0006] The purpose of the utility model is to provide a coating device for the production of aluminum veneer to solve the problem that the coating device for the production of aluminum veneer proposed in the above-mentioned background technology sweeps away dust and impurities through a cleaning roller and blows away with strong wind, but the dust is still inside the outer shell and will still adhere to the surface of the aluminum veneer after flying.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coating device for aluminum single plate production, comprising a conveyor belt and a coating box, wherein the coating box is fixedly connected to the top of the conveyor belt, and a dust removal device and a coating device are respectively arranged inside the coating box.

[0008] The dust removal device includes a dust suction unit and a dust removal unit.

When the aluminum plate is transported to the interior of the coating box through the conveyor belt, the vacuum cleaner is started to remove dust and impurities on the surface of the aluminum plate through the vacuum tube and the dust hood.

[0010] A further improvement is that the cleaning component includes a rotating bearing, a rotating shaft, and a cleaning brush. The two rotating bearings are respectively installed on the front and rear inner walls of the dust hood. The rotating shaft is rotatably connected to the inside of the rotating bearing, and the cleaning brush is fixedly connected to the outside of the rotating shaft. The aluminum plate contacts the cleaning brush during transmission, and the friction force generated between the two drives the rotating shaft inside the cleaning brush to rotate inside the rotating bearing, so that the stubborn impurities on the surface of the aluminum plate are brushed up by the rotation of the cleaning brush and removed by the vacuum cleaner.

[0011] A further improvement is that the dust removal unit includes a fixed bearing, a rotating shaft, a pressing roller, and an electrostatic dust removal film, the two fixed bearings are respectively installed on the front and rear inner walls of the coating box, the rotating shaft is rotatably connected to the inside of the fixed bearing, the pressing roller is fixedly connected to the outside of the rotating shaft, and the electrostatic dust removal film is rollingly connected to the bottom of the pressing roller.

[0012] A further improvement is that grooves are opened on both sides of the top of the coating box, and the electrostatic dust removal film passes through the two grooves, and the external electrostatic dust removal film is sent into the interior of the coating box through the left groove, and passed through the bottom of the pressing roller. The aluminum veneer comes into contact with the pressing roller during transportation and drives the internal rotating shaft to rotate inside the fixed bearing, thereby driving the pressing roller to rotate and adhere the electrostatic dust removal film to the surface of the aluminum veneer, and the remaining dust and impurities on the surface of the aluminum veneer are absorbed by the electrostatic dust removal film.

[0013] A further improvement is that the laminating device includes an electric lifting rod, a U-shaped frame, bearings, rollers, a tensioning roller, a connecting rod, and a laminating scraper. The electric lifting rod is installed on the right top wall of the laminating box, the U-shaped frame is fixedly connected to the bottom of the electric lifting rod, the two bearings are respectively installed on the front and rear sides of the U-shaped frame, the roller is rotatably connected to the inside of the bearing, the tensioning roller is fixedly connected to the outer end of the roller, the connecting rod is fixedly connected to the left side of the U-shaped frame, and the laminating scraper is fixedly connected to the bottom of the connecting rod.

At this time, the electric lifting rod is started to push the U-shaped frame downward, so that the laminating scraper on one side of the U-shaped frame moves downward to press the film on the surface of the aluminum veneer, so that the film is attached to the surface of the aluminum veneer through the laminating scraper and the aluminum veneer conveyed to the right, wherein the film is close to the tensioning roller during the passage, and the tension of the film is adjusted by the tensioning roller, which is more conducive to the laminating work.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 2. The coating device for aluminum veneer production sends the external electrostatic dust removal film into the interior of the coating box through the left slot, and makes it pass through the bottom of the pressing roller. The aluminum veneer contacts the pressing roller during transmission and drives the internal rotating shaft to rotate inside the fixed bearing, thereby driving the pressing roller to rotate and adhere the electrostatic dust removal film to the surface of the aluminum veneer, and the remaining dust and impurities on the surface of the aluminum veneer are absorbed by the electrostatic dust removal film.
