Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sanding device. Background Technology

[0002] Traditional sanding equipment often employs fixed abrasive belt wheels or a single pneumatic cylinder tensioning structure, which suffers from uneven tension after belt wear and low replacement efficiency. While dual-motor driven rotating abrasive rollers can improve accuracy through pneumatic cylinder coarse / fine adjustments, they also increase structural complexity. Existing technologies largely rely on manual intervention for belt tension adjustment (e.g., manual screw adjustment), which is unsuitable for continuous operation and negatively impacts processing efficiency and surface quality consistency. Summary of the Invention

[0003] This utility model provides a sanding device that addresses the problems of existing technologies. It features a novel structure, with two swing arm drive components independently controlling two movable arms, thereby achieving independent control of two passive wheels and realizing real-time tension balance of the sanding belt body, reducing the risk of slippage. Furthermore, it can flexibly drive the movable arms to swing, facilitating the installation and disassembly of the sanding belt body. It is suitable for sanding various materials such as wood and composite materials.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a sanding device, which includes a frame, a sanding belt drive, and a sanding belt body. The sanding belt drive is mounted on the frame. Movable arms are rotatably mounted at both ends of one side of the frame. Driven wheels are rotatably connected to the movable arms. The output end of the sanding belt drive is connected to a drive wheel. The sanding belt body is wound around the drive wheel and the two driven wheels. The frame is also equipped with two swing arm drives, which correspond one-to-one with the two movable arms. The swing arm drives are used to drive the movable arms to swing so that the driven wheels tension or loosen the sanding belt body.

[0006] The frame includes a fixed support and a movable support. The movable support is movably mounted on the fixed support. The two movable arms are rotatably connected to both ends of one side of the movable support. The sanding belt drive and the swing arm drive are respectively mounted on the movable support.

[0007] The fixed bracket is also equipped with a telescopic drive component, the output end of which is connected to the movable bracket, and the telescopic drive component is used to drive the movable bracket to move back and forth.

[0008] The fixed bracket is equipped with a cam swing drive, and the output end of the cam swing drive is connected to a transmission link. The transmission link is movably linked to the movable bracket, and the cam swing drive drives the movable bracket to swing through the transmission link.

[0009] The movable support is also equipped with a dust cover on its outer periphery, and a window is opened on one side of the dust cover, through which the main body of the sand belt between the two passive wheels is exposed.

[0010] The sanding device further includes a lifting mechanism and a lifting frame. The lifting mechanism includes a lifting seat and a lifting adjustment component mounted on the lifting seat. The lifting adjustment component is used to drive the lifting frame to move up and down. One end of the fixed bracket is mounted on one side of the lifting frame.
