Description

Technical Field

[0001] This application relates to a single-sided powder coating device for aluminum panels, specifically a single-sided powder coating device for aluminum panels. Background Technology

[0002] Aluminum composite panels (ACPs) are a type of metal decorative material widely used in building curtain walls, interior decoration, and advertising signs. They are made from high-quality aluminum alloy sheets, formed through sheet metal processing, and surface treated with processes such as spraying, anodizing, or coating. They are lightweight, weather-resistant, fire-resistant, and easy to process.

[0003] The powder coating of aluminum panels (such as polyester, fluorocarbon, etc.) can isolate air and moisture, significantly extending the life of the aluminum panel and preventing fading and chalking. When aluminum panels are used as interior ceilings and partitions, since the back is not visible and the environment is dry, only one side is usually powder coated to save material costs. In the existing technology, some methods of single-sided powder coating involve operators using hand-held powder coating guns, which is inefficient and creates an unfriendly working environment. Another method is to place the aluminum panel in a box for powder coating. Although this method can avoid dust splashing, it requires removing the coated aluminum panel and placing the one to be coated inside the box, which wastes a lot of time. Utility Model Content

[0004] In view of the above problems, this application provides a single-sided powder coating device for aluminum panels, which can avoid dust splashing during the powder coating process and further improve efficiency.

Figure 5 This is a partial structural diagram of the handle provided in an embodiment of this application. The single-sided powder coating device 100 for aluminum panels includes a powder coating box 110, within which a powder coating assembly 120 is installed. The powder coating box 110 is used to contain the powder, preventing powder splashing and facilitating subsequent recovery of excess powder. The powder coating assembly 120 is prior art; it is used to spray powder (such as polyester, fluorocarbon, etc.) onto one side of the aluminum panel. The powder is evenly adsorbed onto the workpiece surface, forming a powdery coating. This powdery coating is then baked at high temperature to achieve leveling and curing, resulting in a final coating with varying effects. One side of the powder coating box 110 is open. Two doors 140 are connected to the two sides of the powder coating box 110 via multiple hinges 130. The two doors 140 can be used alternately, and the aluminum panel to be coated can be fixed inside the door 140. The hinge 130 includes an L-shaped flip shaft 131. One end of the flip shaft 131 is connected to one side of the powder coating box 110 via a sheath shaft 132 and a fixing member 133. The other end of the flip shaft 131 is fixedly connected to the side of the door 140. When the door 140 is opened, it will flip outward and move away from the powder coating box 110 under the support of the flip shaft 131, which will not affect the closing of the other door 140. A pressure-bearing grille 141 is provided on the inner bottom of the door 140, which is used to support the aluminum panel. The door body 140 has at least two vertically arranged through slots 142. An extrusion member 150 is positioned above the pressure-bearing grille 141. The extrusion member 150 is used to press against the aluminum panel. The extrusion member 150 cooperates with the pressure-bearing grille 141 to clamp and fix the aluminum panel. Both the top of the pressure-bearing grille 141 and the bottom of the extrusion member 150 have a certain slope, so that after the aluminum panel is fixed, the top of the aluminum panel tilts towards the side closer to the door body 140, further improving the stability of the fixed aluminum panel. A connecting rod is fixed to the back of the extrusion member 150. The connecting rod passes through the through slot 142 to the outside of the door body 140 and is connected to a fixing block 152. A tension spring 153 connects the fixing block 152 and the door body 140. After the tension spring 153 tightens the extrusion member 150, the extrusion member 150 will tightly press against the aluminum panel, thus completing the fixation of the aluminum panel. The bottom of the powder spraying box 110 is connected to a powder collection trough 111. A collection box is provided at the lower end of the powder collection trough 111. Excess powder will enter the collection trough and then be collected in the collection box for subsequent recycling.

[0023] In this embodiment, during operation, the operator opens one of the doors 140 (hereinafter referred to as the first door 140 for ease of explanation, and the other door 140 as the second door 140). The operator pulls up the pressing member 150 above the first door 140 and places the aluminum panel on the pressure-bearing grille 141. Then, the operator releases the pressing member 150. Under the action of the tension spring 153, the tension spring 153 pulls the fixing block 152. The fixing block 152 further drives the pressing member 150 to move down and reset through the connecting rod, and abuts against the top of the aluminum panel. At this time, the aluminum panel will be clamped on the first door 140. Then, the first door 140 is rotated to close the first door 140 at the opening of the powder spraying box 110. At this time, the powder spraying component 120 inside the powder spraying box 110 can complete the powder spraying of the aluminum panel at the first door 140. At the same time, the operator can fix another aluminum panel to be sprayed on the second door 140. After the aluminum panel at the first door 140 is sprayed, the first door 140 is flipped over and then the second door 140 is flipped over to close the second door 140 at the opening of the powder spraying box 110. The aluminum panel that has been sprayed on the first door 140 is removed and the material is reloaded onto the first door 140. This cycle can be repeated to efficiently complete the spraying operation of the aluminum panel.

[0024] As can be seen from the above, in this embodiment, by setting a powder spraying box 110 and two doors 140 at the opening of the powder spraying box 110, each door 140 is provided with a pressure-bearing grid 141 and an extrusion member 150 for fixing the aluminum single panel to be sprayed. The two doors 140 are used alternately. When one door 140 is closed in the powder spraying box 110, the powder spraying assembly 120 can spray powder onto the aluminum single panel on that door 140. At the same time, the operator can transfer the aluminum single panel to be sprayed to the other door 140, saving the time of loading and unloading materials and greatly improving work efficiency. On the other hand, by setting a powder collection trough 111 and a collection box below the powder collection trough 111, excess powder can be collected into the collection box for subsequent use. In summary, the work efficiency of this application is greatly improved, and dust splashing can be effectively avoided during the powder spraying process.

[0025] In some embodiments, the upper and lower sides of the extruder 150 are connected with powder baffles 154 that match the through groove 142. In this embodiment, by setting the powder baffles to block the through groove 142, powder is prevented from splashing along the through groove 142 to the outside of the powder spraying box 110 during the powder spraying operation.

[0026] In some embodiments, a handle 155 is provided at the extruder 150. In this embodiment, the handle 155 facilitates operation by allowing the operator to hold the handle 155 and drag the extruder 150.

[0027] In some embodiments, the extruder 150 has a mounting groove 156 in the middle, and the handle 155 includes a U-shaped grip 155a. The lower end of the grip 155a extends towards the end near the door body 140 and is connected to two flip blocks 155b. The two flip blocks are rotatably connected to the inner side of the mounting groove 156 through a rotating shaft 155c. The lower end of the flip blocks is fixed with a vertical rod 155d, and the lower end of the vertical rod 155d is formed with a hook 155e. In this embodiment, during the feeding process, the operator holds the handle and drags the extruder 150 upward to leave a sufficient gap between the extruder 150 and the load-bearing grid. Then, the lower end of the aluminum panel is placed on the load-bearing grid, and the upper end of the aluminum panel is pushed to rotate so that it is close to the door 140. At this time, the side of the aluminum panel close to the door 140 will extrude the hook 155e. The hook 155e further drives the handle 155a to flip through the vertical rod 155d. After the operator releases the handle 155a, the extruder plate will abut against the top of the aluminum panel. When the aluminum panel is finished spraying, the operator holds the handle 155a and lifts it upward. During the upward movement of the handle 155a, the extrusion piece 150 will also be moved upward. At the same time, when the handle 155a is pushed by the operator, it will rotate to a certain extent. This rotation is centered on the rotation axis 155c at the flipping block 155b. After the flipping block 155b flips, the vertical rod 155d and the hook 155e below it will tilt outward to push out the aluminum panel, thereby achieving rapid unloading of the aluminum panel and further improving work efficiency.

[0028] In some embodiments, the powder coating assembly 120 includes an integrated base 121 and a base 122. Multiple powder coating guns 123 are connected to the integrated base 121. A powder supply pipe 124 is connected to the rear end of each powder coating gun 123. A connecting rod 121a is fixed to the rear end of the integrated base 121. A steering seat 122a is provided at the front end of the base 122. The middle part of the connecting rod 121a is rotatably connected to the steering seat 122a. A telescopic rod 125 is hinged to the tail end of the connecting rod 121a, and the bottom end of the telescopic rod 125 is hinged to the rear end of the base 122. In this embodiment, the position of the base 122 on the powder coating assembly 120 is determined according to the actual working conditions and fixed inside the powder coating box 110. The extension and retraction of the telescopic rod 125 can further drive the integrated base 121 to rotate up and down. Therefore, the powder coating guns 123 can achieve uniform spraying of one side of the aluminum panel from top to bottom.

[0029] In some embodiments, a support 160 is included, and a powder spraying box 110 is supported on the support 160. A vibration motor acting on the powder spraying box 110 is provided on the support 160. In this embodiment, by providing a vibration motor, when the equipment is stopped, the vibration motor can be turned on to vibrate, thereby causing the powder in the powder collection tank 111 to fall quickly into the collection box for collection, avoiding moisture caused by long-term external residue.
