The outer sides of the two columns 204 are movably sleeved with the same U-shaped frame 207, and the U-shaped frame The top of the lifting plate 205 is located at the top of the U-shaped frame 207. Two springs 203 are symmetrically fixedly connected between the top of the U-shaped frame 207 and the inner top wall of the L-shaped plate 201. The two springs 203 are respectively sleeved on the outside of the two columns 204. The U-shaped frame 207 is equipped with a grinding disc 208 located above the through slot 3. The bottom of the U-shaped frame 207 is symmetrically fixedly connected with two bottom blocks 2014. A guide rod 209 is fixedly connected between the two bottom blocks 2014. The outer side of the guide rod 209 is movably sleeved with a guide plate 2012. The guide plate 2012 is fixedly connected to the guide plate 2012. A cylinder 2021 is fixedly installed, and a mounting plate 2020 is fixedly installed on one end of the cylinder 2021 away from the guide plate 2012. A motor 2019 is fixedly installed on the side of the mounting plate 2020 away from the cylinder 2021. The grinding disc 208 is fixed on the motor 2019. A motor 2010 is fixedly installed in the U-shaped frame 207. A screw rod 2013 is fixedly installed on the motor 2010. The end of the screw rod 2013 away from the motor 2010 is rotatably connected to the U-shaped frame 207. The outer thread of the screw rod 2013 is connected A nut 2011 is provided, a guide plate 2012 is fixed to the bottom of the nut 2011, a support wheel 2017 is installed at the bottom of the guide plate 2012, the bottom surface height of each pressing plate 206 is greater than the bottom end surface height of the support wheel 2017, the bottom end surface height of the support wheel 2017 is greater than the bottom end surface height of the grinding disc 208, and by providing a through groove 3, the bottom end surface of the grinding disc 208 can enter the through groove 3, so that the grinding disc 208 can be completely fitted with the edge of the strip to achieve uniform grinding, and at the same time, it is convenient for the debris generated by grinding to be discharged from the through groove 3;

[0024] In the initial state, the lifting plate 205 fits the bottom of the U-shaped frame 207, and the two springs 203 are in a compressed state. First, the strip is placed on the top of the processing table 1 so that the edge of the strip is located at the through groove 3 and the strip is located below the lifting plate 205. Then, the cylinder 1 202 is started to drive the lifting plate 205 to slide downward along the two columns 204. At the same time, each pressing plate 206 descends and releases the control of the U-shaped frame 207. At this time, the two springs 203 are reset to drive the U-shaped frame 207 to slide downward along the two columns 204. When the supporting wheel 2017 moves downward and contacts the processing table 1, the bottom end surface of the grinding disc 208 is located at The inside of the through groove 3, and then continue to move the lifting plate 205 downward until each pressure plate 206 abuts against the top of the strip to achieve the extrusion and fixation of the strip, and then start the motor 2019 to drive the grinding disc 208 to rotate, and then start the cylinder 2021 to drive the mounting plate 2020 and the motor 2019 to move until the grinding disc 208 contacts the edge of the strip for grinding, and then start the motor 1 2010 to drive the screw rod 2013 to rotate, and drive the guide plate 2012 to slide along the guide rod 209 through the nut 2011, and finally the grinding disc 208 moves horizontally to evenly grind the edge of the strip, thereby improving the trimming efficiency of the edge of the strip.

[0025] Specifically, by Figure 4 It is given that the outer side of the guide plate 2012 is symmetrically fixedly connected with two limit blocks 2016, and the side of the mounting plate 2020 away from the motor 2 219 is symmetrically fixedly connected with two side rods 2018, and the ends of the two side rods 2018 away from the mounting plate 2020 respectively penetrate the two limit blocks 2016 and are fixedly connected with the side blocks 2015, and the two side rods 2018 are movably connected with the two limit blocks 2016 respectively;

[0026] When the mounting plate 2020 is in use, it drives the two side rods 2018 to move. Since the two limit blocks 2016 are respectively sleeved on the outside of the two side rods 2018, they limit the two side rods 2018 and the mounting plate 2020, thereby ensuring the stability of the mounting plate 2020 and the grinding disc 208 when moving.
