Initially, the fourth spring 157 is in a stretching state, the upper portion of the blocking slider 154 is located in the blanking frame 152 to block the aluminum alloy hollow pipe, when the aluminum alloy hollow pipe needs to be added, the stretching rod of the cylinder 166 can be started to stretch to drive the special-shaped rod 161 to move left, the special-shaped rod 161 does not abut against the blanking valve 156 after moving left, at this time, the blanking valve 156 moves upwards to reset under the action of the fourth spring 157, the blanking valve 156 drives the second connecting rack 165 to move upwards when moving upwards, the second connecting rack 165 moves upwards to drive the blocking slider 154 to move downwards through the missing gear 163 and the first connecting rack 164, the blocking slider 154 does not block the aluminum alloy hollow pipe after moving downwards, at this time, the aluminum alloy hollow pipe continues to slide down and is blocked by the blanking valve 156, after the aluminum alloy hollow pipe is blocked by the blanking valve 156, the cylinder 166 can be started to retract to drive the special-shaped rod 161 to move rightwards to reset, the special-shaped rod 161 can push the blanking valve 156 to move downwards through the upper inclined surface when moving rightwards, the fourth spring 157 is stretched again, the blanking valve 156 drives the blocking slide block 154 to move upwards again through the second connecting rack 165, the missing gear 163 and the first connecting rack 164 when moving downwards to block the aluminum alloy hollow tube on the rear side, the aluminum alloy hollow tube on the front side is not blocked any more after the blanking valve 156 moves downwards, and the aluminum alloy hollow tube on the front side falls on the material placing frame 3, so that manual work is not needed to pull the blanking valve 156 and the blocking slide block 154 to move, and manpower is effectively saved.

As shown in fig. 1, 15 and 16, the discharging device 17 further includes a stopper 171, a fifth spring 172 and a connecting block 173, the stopper 171 is connected to the left side of the special-shaped rod 161, the fifth spring 172 is connected between the fixed ring 9 and the supporting plate 5, the connecting block 173 is connected to the fixed ring 9, and the stopper 171 abuts against the connecting block 173.

Initially, the fifth spring 172 is in a stretched state, the special-shaped rod 161 drives the blocking rod 171 to move leftward when moving leftward, the blocking rod 171 does not abut against the connecting block 173 any more after moving leftward, at this time, the annular sleeve 81 moves leftward under the action of the fifth spring 172, the annular sleeve 81 moves leftward to drive all devices thereon to move leftward together, the fixed ring block 9 does not overlap the first rotating shaft 7 and the grinding shaft 8 any more after moving leftward, at this time, the grinding shaft 8 swings downward under the action of the torsion spring 11, the telescopic rod of the air cylinder 166 also contacts the second sliding frame 131 when extending, when the telescopic rod of the air cylinder 166 moves to contact the second sliding frame 131, the telescopic rod of the air cylinder 166 continues to extend to drive the second sliding frame 131 to move leftward, the third spring 135 is compressed, at this time, since the pressing block 123 does not fix the hollow aluminum alloy tube, the second sliding frame 131 can push out the hollow aluminum alloy tube when moving leftward, therefore, the aluminum alloy hollow pipe does not need to be dismounted manually, manpower is effectively saved, the special-shaped rod 161 can drive the blocking rod 171 to move rightwards to push the connecting block 173 to move rightwards when moving rightwards, so that the annular sleeve 81 is driven to move rightwards to reset, the annular sleeve 81 can drive the grinding shaft 8 to swing upwards to reset when moving rightwards, the torsion spring 11 is compressed again, and then grinding can be continuously carried out.

The above examples are merely representative of preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, various changes, modifications and substitutions can be made without departing from the spirit of the present invention, and these are all within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
