An intersection cavity 118 is provided in the center of the grinding disc 112. The intersection cavity 118 is located on one side of the center of the port at the lower end of the air flow channel 114 and is connected to the port at the lower end of the air flow channel 114. One end of the groove 116 is connected to the intersection cavity 118, and the other end of the groove 116 is connected to the external space of the outer side surface of the grinding disc 112; the exhaust component 110 is located inside the chassis 104, and the air inlet of the exhaust component 110 is connected to the upper end of the air flow channel 114, and a filter is provided in the passage between the air inlet of the exhaust component 110 and the upper end of the air flow channel 114.

[0035] The curtain wall panel 206 to be polished is fixed on the workbench 100, and the motor 108 and the exhaust component 110 are started to drive the grinding disc 112 to rotate. After the lower surface of the grinding disc 112 contacts the curtain wall panel 206 to be polished, the upper surface of the curtain wall panel 206 to be polished is polished. The dust and debris generated during the grinding process are sandwiched between the lower surface of the grinding disc 112 and the upper surface of the curtain wall panel 206 to be polished. The exhaust component 110 exhausts air from the air flow channel 114 to the inner space of the groove 116, and the external air is sucked into the groove 116 from the outside of the grinding disc 112.

[0037] Curtain wall panels 206 to be polished of different sizes and shapes can be fixed on the workbench 100 by replacing the template 122 with a matching cavity 124, and fed upward by electromagnetic drive without manual pushing or lifting, which not only improves work efficiency but also improves safety. It should be understood that the installation position of the control button 130 can be far away from the curtain wall panel 206 to be polished, so as to avoid a small amount of escaping dust from endangering the health of the workers.

[0038] Combination Figure 4 and Figure 5 As shown, in some exemplary implementations of the present embodiment, the transmission shaft 106 includes a telescopic shaft 132, a guide sleeve 134, and a fixed shaft 136, the fixed shaft 136 is rotatably connected to the chassis 104, the upper end of the fixed shaft 136 is transmission-connected to the output shaft of the motor 108, the lower end of the fixed shaft 136 is fixedly connected to the upper end of the guide sleeve 134, the upper end of the telescopic shaft 132 is inserted into the guide sleeve 134 and is slidably connected to the guide sleeve 134 up and down, the outer side of the telescopic shaft 132 is fixedly connected to a key bar 138, the key bar 138 is arranged in the vertical direction, and a key groove is provided on the inner side of the lower end of the guide sleeve 134 140, the key bar 138 is located on the inner side of the key slot 140, and when the guide sleeve 134 rotates, it pushes the key bar 138 and the telescopic shaft 132 to rotate; a first air channel 142 is provided in the center of the telescopic shaft 132, which runs through from top to bottom, and the lower end of the first air channel 142 is connected to the intersection cavity 118, and a second air channel 144 is formed in the internal space of the guide sleeve 134, and a third air channel 146 is provided at the center of the lower end of the fixed shaft 136, and an air hole 148 is provided on the outer side of the fixed shaft 136, and the air hole 148 is connected to the third air channel 146, and the first air channel 142, the second air channel 144, the third air channel 146, and the air hole 148 constitute the air flow channel 114.

[0039] When the curtain wall panel 206 to be polished is fed upward, the squeezing force between the grinding wheel 112 and the curtain wall panel 206 to be polished is always less than or equal to the weight of the grinding wheel 112 and the telescopic shaft 132 (without considering the friction force), which can avoid the degradation of the polishing quality due to excessive feeding speed.

[0040] In some exemplary implementations of the present embodiment, a fixed plate 204 is fixedly connected to the upper surface of the grinding disc 112, the lower end of the telescopic shaft 132 passes through the fixed plate 204 and is fixedly connected to the fixed plate 204, a spring 150 is provided between the guide sleeve 134 and the fixed plate 204, the lower end of the spring 150 abuts against the fixed plate 204, and the upper end of the spring 150 is connected to the guide sleeve 134.

The greater the upward distance of the curtain wall panel 206 to be polished, the greater the squeezing force between the grinding wheel 112 and the curtain wall panel 206 to be polished. When the polishing efficiency needs to be improved or the polishing quality requirements are not high, the squeezing force between the grinding wheel 112 and the curtain wall panel 206 to be polished can be increased, thereby improving work efficiency.
