Description

Technical Field

[0001] This utility model relates to the field of solid wood furniture processing technology, specifically to an electrostatic adsorption type solid wood furniture spraying equipment. Background Technology

[0002] Before solid wood furniture is assembled, each individual furniture board needs to be sprayed. Since most wood boards are insulating, a conductive liquid needs to be applied to their surface before electrostatic adsorption spraying, followed by painting and drying. This method often requires multiple pieces of equipment, which undoubtedly increases the company's investment costs and reduces work efficiency. To address this, we propose an electrostatic adsorption solid wood furniture spraying device to solve the problems mentioned in the background. Utility Model Content

[0005] Furthermore, the conductive liquid application mechanism includes a conductive liquid storage tank and a fixed frame. The conductive liquid storage tank is fixedly connected to the top of the lifting frame plate, and the fixed frame is fixedly connected to the bottom of the lifting frame plate. A rotating rod is rotatably connected to the fixed frame via a limiting rotating ring. A rotating cylinder is fixedly connected to the right end of the rotating rod. Several through-holes are equidistantly arranged around the rotating cylinder. Absorbent cotton is adhered to the outer surface of the rotating cylinder. An inlet pipe communicating with the rotating cylinder is fixedly connected to the center position on the right side of the rotating cylinder. A first liquid passage pipe communicating with the conductive liquid storage tank is fixedly connected to the conductive liquid storage tank. One end of the first liquid passage pipe passes through the inlet pipe and extends into the interior of the rotating cylinder.

[0006] Furthermore, the painting mechanism includes a paint tank and a flow divider shell, which are fixedly connected to the top and bottom of the lifting frame plate, respectively. The paint tank and the flow divider shell are interconnected through a second liquid pipe, and a number of spray nozzles that are interconnected with the bottom of the flow divider shell are fixedly connected thereto.

[0007] Furthermore, two support plates are integrally formed and installed on both the left and right sides of the lifting frame plate, and uprights are fixedly installed at the bottom of the support plates. Limiting pressure rollers are rotatably connected between the two opposing uprights.

[0008] Furthermore, two drive rollers are rotatably connected to the inner side of the frame, and the drive belt is mounted on the two drive rollers.

Based on the board thickness, the height of the second connecting plate and the lifting frame is adjusted using telescopic components. A limiting roller provides a limit from above the board. Conductive liquid from the storage tank is transported to the rotating drum via a first liquid pipe. During board transport, the rotating drum rotates under the connection of a fixed frame, a limiting ring, and a rotating rod.

A lifting frame plate 6 is fixedly installed between the two second connecting plates 5. A conductive liquid application mechanism 7, a painting mechanism 8, and a hot air dryer 9 are installed sequentially from left to right on the lifting frame plate 6. The hot air dryer 9 is fixedly installed at the bottom of the lifting frame plate 6 for drying the painted boards.

[0019] The conductive liquid application mechanism 7 includes a conductive liquid storage tank 71 and a fixing frame 72. The conductive liquid storage tank 71 is fixedly connected to the top of the lifting frame 6, and the fixing frame 72 is fixedly connected to the bottom of the lifting frame 6. A conductive liquid adding pipe is fixedly connected to the top of the conductive liquid storage tank 71, and a transparent viewing glass window is provided on the surface of the tank to observe the remaining conductive liquid level inside. A rotating rod 74 is rotatably connected to the fixing frame 72 via a limiting rotating ring 73. The limiting rotating ring 73 connects and supports the rotating rod 74, which can achieve axial limitation and ensure its stability during rotation. The right end of the rotating rod 74 is fixedly connected to... A rotating cylinder 75 has several through-holes 76 evenly spaced around it. A water-absorbing cotton 77 is bonded to the outer surface of the rotating cylinder 75. An inlet pipe 78 is fixedly connected to the center of the right side of the rotating cylinder 75 and communicates with it. A first liquid passage pipe 79 is fixedly connected to the conductive liquid storage tank 71 and communicates with it. One end of the first liquid passage pipe 79 passes through the inlet pipe 78 and extends into the interior of the rotating cylinder 75. An electric control valve is installed on the first liquid passage pipe 79 to control the flow rate of the conductive liquid and ensure that the conductive liquid that seeps into the water-absorbing cotton 77 through the through-holes 76 is neither too much nor too little.

[0020] The painting mechanism 8 includes a paint tank 81 and a flow divider 82. The paint tank 81 and the flow divider 82 are fixedly connected to the top and bottom of the lifting frame 6, respectively. The top of the paint tank 81 is fixedly connected to a paint adding pipe, and the surface of the tank is provided with a transparent viewing glass window to observe the remaining paint inside. The paint tank 81 and the flow divider 82 are interconnected by a second liquid pipe 83. An electric control valve is installed on the second liquid pipe 83 to control the paint flow rate. The bottom of the flow divider 82 is fixedly connected to several nozzles 84 that are interconnected with it. Specifically, the nozzles 84 are electrostatic adsorption nozzles. The core principle is to charge the atomized droplets through a high-voltage electrostatic field and accurately adsorb them onto the target surface, which greatly improves the painting efficiency and reduces waste. This is a mature existing technology and will not be described in detail here.

During the board conveying process, the rotating drum 75 rotates under the connection of the fixed frame 72, the limiting rotating ring 73 and the rotating rod 74. The conductive liquid seeps into the absorbent cotton 77 through the penetration hole 76 to achieve uniform coating of conductive liquid on the surface of the board. The paint in the paint tank 81 can be transported to the inside of the diversion shell 82 through the second liquid pipe 83, and the paint is sprayed through multiple nozzles 84 until the board is conveyed to the bottom of the hot air dryer 9 for drying after painting.
