Description

Technical Field

[0001] This utility model relates to the field of PVC door panel technology, specifically a multi-stage sanding mechanism for PVC door panels. Background Technology

[0002] Sanding, also known as polishing, refers to the process of smoothing wood panels using sandpaper or a sanding machine to achieve the desired finish. A sanding machine is a mechanical device with an automatic feeding system that performs sanding operations.

[0003] For example, Chinese Patent CN109500678B discloses a wood sanding machine, which relates to the field of sanding machine technology. The wood sanding machine includes a transmission mechanism for transporting wood boards and a first sanding mechanism, a flipping mechanism, a second sanding mechanism, and a four-sided sanding mechanism arranged sequentially along the transmission direction of the transmission structure. The transmission mechanism can sequentially transfer the wood boards to the first sanding mechanism, the flipping mechanism, the second sanding mechanism, and the four-sided sanding mechanism for sanding one side, flipping the wood board, sanding the other side, and sanding all four sides of the wood board. This alleviates the technical problems of low working efficiency, low sanding accuracy, and high production cost of existing sanding machines. However, traditional sanding machines are prone to deviation during the conveying and sanding process, making precise positioning impossible and affecting the sanding effect. Therefore, a multi-pass sanding mechanism for PVC door panels is proposed to solve the above problems. Utility Model Content
