The movement of the resisting block 50 can drive the sliding block 46 to move. The movement of the sliding block 46 can drive the grinding roller 44 to move. During the movement, the grinding roller 44 can use the third gear 48 and the rack 49 to drive the grinding roller 44 to rotate, so that the grinding roller 44 can move and rotate at the same time, so as to grind the groove of the tongue needle. When the resisting block 50 contacts the wedge block 42, the inclined surface on the wedge block 42 can be used to drive the resisting block 50 to move upward, so that one side of the resisting block 50 is away from the protrusion 43. At this time, the sliding block 46 can be reset and moved under the action of the fourth spring 47 to grind the groove again. At the same time, the resisting block 50 can be reset and moved under the action of the two fifth springs 52, and the subsequent protrusion 43 will continue to push the resisting block 50 to move, so as to drive the grinding roller 44 to reciprocate multiple times. When the abutment seat 23 contacts the support platform 7, it can drive the support platform 7 to move downward and compress the spring telescopic rod 6 until the bottom of the abutment seat 23 contacts the top of the support platform 7. At this time, the bottom end of the abutment rod 28 is separated from the moving frame 38, and the moving frame 38 can be reset and moved under the action of the third spring 40; When the grinding head 9 contacts the tongue needle, the first motor 4 is started. The first motor 4 can drive the turning plate 3 to rotate. During the rotation of the turning plate 3, the two clamping plates 13 can be used to drive the tongue needle to rotate, enabling each surface of the tongue needle to be ground. At the same time, during the grinding process, the sliding rod 26 can reciprocate up and down in the first rotating ring 24 by means of the first spring 27, ensuring that the grinding head 9 always contacts the surface of the tongue needle until one end of the tongue needle is ground; Then, start the first motor 4 to rotate in the reverse direction to drive the tongue needle to return to its original position, and start the fourth motor 29 to rotate in the reverse direction to drive the grinding head 9 to move back, so that the grinding head 9 moves away from one end of the tongue needle until it moves to a safe distance. Then, start the electric turntable 5 to drive the support platform 7 to rotate. During the rotation of the support platform 7, the tongue needle can be driven to turn around, and then the other end of the tongue needle can be ground by using the above method.
