[0020] Example 2 Please refer to Figure 2 and Figure 3 The feeding mechanism 2 comprises a fixed frame 201 welded on the top rear side of the machine body 1, the inside of the fixed frame 201 is rotatably connected with a first lead screw 202, the first lead screw 202 is threadedly connected with a moving plate 205, the moving plate 205 is slidably connected on the outer wall of a first guide rod 203, the first guide rod 203 is fixedly installed in the inside of the fixed frame 201, the outer wall of the fixed frame 201 is provided with a first stepper motor 204 for driving the first lead screw 202 to rotate, and the inside of the moving plate 205 is rotatably connected with a first electric push rod 206, and the output end of the first electric push rod 206 is fixedly connected with a first mounting plate 210.

[0021] Please refer to Figure 3As shown, a first motor 207 is provided on the outer wall of the movable plate 205. A drive wheel 208 is fixedly connected to the output end of the first motor 207. A driven wheel 209 is fixedly installed on the outer wall of the first electric push rod 206. The drive wheel 208 is connected to the driven wheel 209 via a belt. A first rotating ring 213 is rotatably connected inside the first mounting plate 210. A second motor 211 is provided on the outer wall of the first mounting plate 210. The output end of the second motor 211 is fixedly connected to the first gear 212. Teeth that mesh with the first gear 212 are connected to the first rotating ring 213. Two sets of second electric push rods 214 are fixedly installed on the first rotating ring 213. The output ends of the second electric push rods 214 are fixedly connected to the clamping plate 215.

[0022] Those skilled in the art will understand that the output of the first stepper motor 204 drives the first lead screw 202 to rotate, causing the moving plate 205 to reciprocate up and down along the outer wall of the first guide rod 203, thereby enabling the first mounting plate 210 and the two sets of clamping plates 215 to move together with the moving plate 205; the output of the first motor 207 drives the drive wheel 208 to rotate, and under the action of the belt, the driven wheel 209 and the first electric push rod 206 rotate together, driving the first mounting plate 210 and the two sets of clamping plates 215 to rotate together; by controlling the output of the first electric push rod 206 to extend or retract, the first mounting plate 210 and the two sets of clamping plates 215 can be moved forward or backward together. In summary, under the action of the output end of the first motor 207, the first mounting plate 210 is made to be in a vertical state. Then, under the action of the output end of the first stepper motor 204, the first mounting plate 210 moves to a height position compatible with the conveyor 101. Next, under the action of the output end of the first electric push rod 206, the first mounting plate 210 reciprocates back and forth, so that the center of the first rotating ring 213 and the center of the metal shaft to be processed conveyed on the conveyor 101 are on the same horizontal line. This allows the metal shaft to accurately enter the first rotating ring 213. Finally, the output of the two sets of second electric push rods 214... Under the action of the end, the two sets of clamping plates 215 are brought closer to each other to clamp and fix the metal shaft. Then, under the action of the output end of the first motor 207, the first mounting plate 210 is driven to rotate, causing the clamped metal shaft to be in an inclined state. Then, under the action of the output end of the first electric push rod 206, the center of the inclined metal shaft and the center of the inclined feed port 103 are on the same straight line. Then, under the action of the output end of the first step motor 204, the clamped metal shaft is driven to move downward along the outer wall of the first guide rod 203 and extend into the interior of the cooling box 102 through the feed port 103.
