Here we set the number of discs in the first disc group and the second disc group to 5 respectively.

A group of guide rail wheels 9 with grooves are installed on the outside of both sides of the support frame 5, and a track slide bar 2 is respectively arranged on the two inner sides of the hoisting frame 1. The material of the track slide bar 2 can be selected as a smooth surface. White steel, the width of the groove road of guide rail wheel 9 matches with the size of depth and track slide bar 2. The special-shaped sanding mechanism is mounted on the track slide bar 2 on the hoisting frame 1 through guide rail wheels 9, and the special-shaped sanding mechanism can slide back and forth on the track slide bar 2.

Through the above assembly, the special-shaped sanding mechanism is installed on the hoisting frame 1. When the power is turned on, the grinding disc rotating motor 7 works, driving the rotating wheel 12 to start rotating, and under the transmission effect of the transmission V-belt 8, the belt is tilted. Angled grinding disc 3 rotates at high speed. The grinding discs 3 of the first grinding disc group and the grinding discs 3 of the second grinding disc group are arranged in a staggered manner, intensively sanding the special-shaped workpieces with patterns of different depths that are in contact with the disc brushes 32 without dead ends, so that the sanding operation is more thorough. In the actual production process, it has been found through a large number of experiments that the utility model can effectively sand the special-shaped workpieces with concave-convex patterns on the surface, meet the production needs, and improve product quality.

In order to make the sanding effect better, optimally, we are provided with a swinging assembly on one side of the grinding disc rotating motor 7, as shown in Figure 4, including a swinging motor 14 and a swinging connecting rod 15, and the swinging motor 14 is provided with a turntable 16 connected to After the power is turned on, the swing motor 14 works to drive the turntable 16 to rotate at a constant speed. One end of the swing connecting rod 15 is fixedly connected on the edge of the rotating disk 16, and when connected, a connecting piece can be set on the edge of the rotating disk 16. The other end of the swing connecting rod 15 is fixedly connected on the outer side of the support frame 5, near the millstone rotating motor 7, above the guide rail wheel 9, when connecting, a connector can be welded on the outside of the support frame 5, and the swing connecting rod 15 One end is fastened to this connector. Turn on the power, the turntable 16 on the swing motor 14 starts to rotate, the swing connecting rod 15 reciprocates with the turntable 16, and then drives the grinding disc 3 to reciprocate along the track slide bar 2 while rotating at a high speed, to correct the unevenness on the workpiece. The patterns are sanded in all directions.

In the production process, due to the different thicknesses of the workpieces that need to be sanded, optimally, when the hoisting frame 1 is installed on the frame of the special-shaped combination sander, a lifting assembly can be provided on the top of the hoisting frame 1, including a lifting motor 17 , two telescopic lifting columns 18 and a connecting shaft 19, the lifting motor 17 is located at the top of one of the lifting columns 18 to provide power for the lifting of the lifting columns 18, and a connecting shaft 19 is connected between the two lifting columns 18 tops. The bottom end of lifting column 18 is fixed on the lifting frame 1 upper end, and the upper end of lifting column 18 is fixed on the frame of special-shaped combination sander top, and whole lifting frame 1 is fixed on the special-shaped combination sander by lifting assembly. When the thickness of the polished workpiece changes, the height of the combination of the two grinding discs can be changed through the lifting combination. After the power is turned on, when the up or down button is pressed, the lifting motor 17 is driven by the connecting shaft 19 to raise or lower the entire grinding disc assembly by the same displacement, so as to adapt to workpieces of different thicknesses. In actual operation, we generally only make small adjustments to the rising or falling displacement of the grinding disc combination, and the lifting motor 17 rotates too fast. At this time, we can install a reducer on the upper end of each lifting column 18 to slow down the lifting. The operating speed of the motor 17 makes the two lifting columns 18 rise or fall in a slow state, preventing the displacement from being too high or too low in an instant and failing to reach the desired height.

The above is only a preferred embodiment of the present utility model, and the scope of protection of the present utility model is not limited thereto. Any transformation or replacement disclosed by any person familiar with the technology in the present utility model should be covered by the present utility model. within the range.
