Description

A kind of decoration wood surface polishing device

Technical Field

The utility model belongs to the technical field of wood processing equipment, and in particular relates to a surface polishing device for decorative wood.

Background Art

Before decorative wood is used, it needs to be polished, that is, the surface of the workpiece is modified using polishing tools and abrasive particles or other polishing media.

The existing patent application number is: 202011264169X, which discloses a wood surface polishing device, including a working platform, a fixed plate fixed on the working platform, a threaded sleeve fixed on the fixed plate, a screw on the threaded sleeve, an extrusion plate fixedly connected to the screw, a mounting frame fixed on the working platform, a slide groove on the mounting frame, and a movable plate, etc. The device places the wood on the working platform, rotates the screw, and the extrusion plate clamps the wood to prevent the wood from being offset during polishing. The protective pad can be used to prevent the extrusion plate from squeezing and deforming the wood, thereby better protecting the wood. The electric telescopic rod and the motor are started through the control panel to make the polishing sheet contact with the wood to polish the surface, and wood of different sizes can be polished. After analyzing the device, it is found that when the extrusion plates on both sides are controlled to extrude and position the wood placed on the working platform, an electric telescopic rod is connected to one side of each extrusion plate, and the extrusion plate is driven to move by the electric telescopic rod. Although this method can control each extrusion plate to move independently, a large number of electric telescopic rods need to be consumed, which will greatly increase the cost of use and lack economic efficiency in structure.

Therefore, in view of the above-mentioned problems, the present technical solution proposes a device for polishing the surface of decorated wood.
