Description

Technical Field

[0001] The utility model belongs to the technical field of coating devices, in particular to a coating device for processing aluminum alloy plates. Background Art

[0002] Aluminum alloy is an alloy composed of aluminum and other metal or non-metal elements. It has the characteristics of light weight, high strength, corrosion resistance and excellent conductivity. Therefore, in the field of building decoration, aluminum alloy is often used to make decorative materials, generally including window frames, door frames, etc. The surface of these aluminum alloy materials often needs to be covered with a layer of protective film to protect the product surface from scratches, pollution, water vapor, etc., which can change the appearance and performance of the surface, such as increasing gloss, waterproof, dustproof, scratch-resistant and other characteristics.

[0003] Publication No. CN213223371U discloses an aluminum plate coating device, including an air-cooled box, a support column, an active roller, a driven roller, a coating roll, a coating roll, a rotating rod, a cleaning brush, a dust suction fan and a dust suction pipe. The coating roll is located directly above the driven roller. The aluminum plate passes between the coating roll and the driven roller after passing through the active roller. A film is wound on the coating roll. One end of the film is attached to the upper surface of the aluminum plate and passes through the coating roll synchronously with the aluminum plate. One end of the rotating rod is hinged to the top inner wall of the air-cooled box, and the other end is fixedly connected to one end of the cleaning brush, and the other end is attached to the upper surface of the aluminum plate. The dust suction fan is fixedly installed on the top of the air-cooled box. One end of the dust pipe is connected to the air inlet of the dust suction fan, and the other end passes through the top inner wall of the air cooling box and is fixedly connected to the other end of the rotating rod. This can more thoroughly clean the upper surface of the aluminum plate, improve the cleaning effect, and prevent bubbles from appearing in the aluminum plate coating. However, the above device still has certain shortcomings when used: since the distance between the coating roller and the driven roller cannot be adjusted, it is not convenient to coat aluminum plates of different thicknesses, and during long-term use, the driven roller and the coating roller may be skewed, resulting in poor coating pressing effect on one side of the aluminum alloy plate. For this reason, we propose a coating device for aluminum alloy plate processing. Utility Model Content

[0004] In order to solve the problem that the distance between the laminating roller and the driven roller cannot be adjusted in the current laminating device, which makes it inconvenient to perform laminating operation on aluminum plates of different thicknesses, and in the process of long-term use, both the driven roller and the laminating roller may be skewed, resulting in poor laminating pressing effect on one side of the aluminum alloy plate, the utility model provides the following technical solutions: a laminating device for aluminum alloy plate processing, comprising a box body, wherein an active roller, a driven roller and a laminating roll are arranged in the box body, a transmission belt is connected between the active roller and the driven roller, a roller pressing assembly is arranged above the active roller, and the roller pressing assembly The parts include a cylinder, a coating roller, a roller frame and a mounting seat, the coating roller is rotatably connected to the roller frame through a rotating shaft, sliding rods are respectively provided at both ends of the top of the roller frame, the sliding rods can be vertically slid into the bottom of the mounting seat, the top of the mounting seat is fixedly connected to the telescopic end of the cylinder, the two sliding rods are circumferentially sleeved with springs, the springs are compression springs, the two springs are both arranged between the roller frame and the mounting seat, the lower part of the sliding rod is provided with a threaded portion, the top of the roller frame is provided with a threaded hole with a size matching the threaded portion, and the threaded portion can be threaded and movably connected in the threaded hole.

[0005] Preferably, the box body has an outlet at one side close to the rolling assembly, and an inlet is provided at a side of the box body opposite to the outlet, and the heights of the outlet and the inlet both match the height of the top of the transmission belt.

[0006] Preferably, a cleaning brush is provided at the top of the inlet, and the head of the cleaning brush is slidably connected to the bottom of the inlet, so that dust on the upper surface of the aluminum alloy plate can be cleaned by the cleaning brush when the aluminum alloy plate is fed into the box through the inlet.

[0007] Preferably, a sliding groove begins at the bottom of the mounting seat, the sliding rod can slide in the sliding groove, a limiting ring is provided at the top of the sliding rod, a connecting edge is provided at the bottom of the sliding groove, the diameter of the connecting edge is smaller than the diameter of the sliding groove, when the sliding rod slides downward, the limiting ring and the connecting edge contact each other, which can prevent the sliding rod from falling off the sliding groove.

[0009] Preferably, a connecting rod is slidably inserted into the coating roll, and both ends of the connecting rod are connected to the bottom of the inner cavity of the box through side plates.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] By rotating the two slide bars through the threads, the threaded parts of the two slide bars can be screwed in / out of the threaded holes of the roller frame, thereby adjusting the inclination of the coating roller so that the bottom of the coating roller is parallel to the top of the driven roller, and then the aluminum alloy plate is sent into the box through the entrance. The dust on the upper surface of the aluminum alloy plate can be cleaned by the cleaning brush when passing through the entrance. The cleaned aluminum alloy plate is placed on the transmission belt, and then one end of the film wrapped on the coating roll is pulled out and flatly attached to the end of the aluminum alloy plate close to the coating roller, and then the active roller is started to rotate, and the driven roller is driven to rotate synchronously through the transmission belt. The movement of the transmission belt moves the aluminum alloy plate horizontally toward one side of the coating roller. When the aluminum alloy plate moves to the bottom of the coating roller, the control cylinder The telescopic end of the film is extended to drive the coating roller to descend and press the film roller against the surface of the aluminum alloy plate. When the coating roller contacts the surface of the aluminum alloy plate and continues to descend, the slide bar slides up along the slide groove and is buffered by compressing the spring to avoid crushing the surface of the aluminum alloy plate. The film is completely covered by the movement of the aluminum alloy plate. The coating roll rotates around the connecting rod as the film is delivered, and then is delivered from the box through the outlet. The two slide bars are screwed in / out of the threaded holes of the roller frame to adjust the inclination of the coating roller so that the bottom of the coating roller is parallel to the top of the driven roller. This ensures that the pressure is evenly distributed on the surface of the film and the aluminum alloy plate during coating, thereby achieving a uniform pressing effect.
