By setting a fixed worktable and a movable worktable on the frame, and setting a material guiding mechanism on the fixed worktable and the movable worktable to transport the workpiece, a grinding mechanism is set on both the fixed worktable and the movable worktable to grind the workpiece transported by the material guiding mechanism, which greatly improves the grinding efficiency.

[0004] However, the material guiding mechanism, through the drive wheel, driven wheel, and conveyor belt, drives the drive wheel shaft to rotate via the drive device, thereby driving the conveyor belt to transport the workpiece. During the transport process, the workpiece is ground, which generates a large amount of debris. The existing technology lacks a debris removal mechanism, requiring the machine to be stopped and the debris to be removed manually. Furthermore, as the debris accumulates and adheres during processing, it causes wear between the drive wheel, driven wheel, and conveyor belt, thus affecting the service life of the equipment. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a brushing device for the opening of a car headrest tube, so as to solve the problem that the debris generated during grinding cannot be effectively removed.

A feeding mechanism is located at one end of each conveying support to feed materials onto it, while a discharging mechanism is located at the other end to unload the polished workpiece. Protective covers are located on opposite sides of the bases, each containing a polishing mechanism and a dust removal mechanism. The polishing mechanism polishes the workpiece conveyed on the conveying supports, while the dust removal mechanism removes the debris generated during polishing.

A dust extraction pipe is connected to the dust extraction fan, and the end of the dust extraction pipe is located on the side of the limiting plate.

[0011] A further improvement is that the feeding mechanism includes a guide bracket, which is inclinedly disposed at one end of the conveying bracket, and a storage baffle is provided on the side of the guide bracket, through which the workpiece is placed and limited for conveying.

[0012] A further improvement is that the feeding mechanism includes a feeding bracket, which is inclinedly arranged at the other end of the conveying bracket. A receiving box is provided on the frame, which is located on the lower side of the end of the feeding bracket. A brush plate is provided on the side of the feeding bracket.

[0014] The beneficial effects of this utility model are as follows: The feeding mechanism enables rapid feeding of workpieces, which continuously slide down the guide bracket onto the conveyor bracket. As the conveying screw rotates, the workpieces roll one by one on the conveyor bracket. Grinding wheels on both sides grind and deburr the ends of the conveyed workpieces. A limiting plate on the upper side of the conveyor bracket limits the conveyed workpieces, ensuring stable transport. A dust extraction pipe is installed on one side of the limiting plate, positioned close to the workpiece grinding location.
