The displacement cross plate 20 is fixedly installed on the inner top of the punching machine 32, and the discharge cavity 29 is symmetrically fixedly installed on both sides of the interior of the punching machine 32, and the discharge cavity 29 is located at the side end of the alignment bottom plate 35.

A discharge hole is provided on the bottom end of the receiving cavity 11 near the blocking bottom plate 13. The first spring 23 is connected to the end of the movable bracket 9 facing away from the connecting rope 8. The interiors of the discharge cavity 29 and the contact cavity 27 are both hollow, and the interiors of the discharge cavity 29 and the contact cavity 27 are both inclined at 45°. The positioning bottom plate 35 is vertically aligned with the counterweight 15, the third rack 22 is aligned with the second gear 12, the nylon brush 10 is aligned with the upper mold 21, the nylon brush 10 is vertically aligned with the center of the interior of the receiving cavity 11, and the inner bottom end of the receiving cavity 11 is inclined at 45°, and the top of the blocking bottom plate 13 is in contact with the bottom end of the receiving cavity 11.

[0028] The working principle of Example 1 is as follows: when in use, the external rotor raw material is first input into the punching machine 32 so that the raw material can be aligned with the displacement cross plate 20 and the lower mold 3. Subsequently, the displacement cross plate 20 is connected to the driving system at the top of the punching machine 32 so that when the starting system is turned on, the displacement cross plate 20 can be driven to move downward. At this time, when the displacement cross plate 20 moves downward, the raw material can be punched until the upper mold 21 moves to contact the raw material. Moreover, when the raw material is punched, a conveyor belt is installed inside the punching machine 32 so that the raw material after punching can be transported outward through the conveyor belt to complete the punching of the rotor. Subsequently, the driving system inside the punching machine 32 is operated again to drive the displacement cross plate 20 to move upward. At this time, when the displacement cross plate 20 moves upward for a distance, it can drive the first gear 7 to move to contact the surface of the fourth rack 33, so that the first gear 7 can drive the shaft 6 to rotate, so that the connecting rope 8 can pull the movable bracket 9 to move toward one end close to the shaft 6, and the card key at the top of the movable bracket 9 slides in the card groove inside the L-shaped bracket 24 and the displacement cross plate 20, so that the movable bracket 9 can be supported to move in a straight line. When the movable bracket 9 is displaced, it can drive the receiving cavity 11 to displace at the same time, and when the receiving cavity 11 is displaced, it can drive the second gear 12 to displace along the surface of the third rack 22, so that the nylon brush 10 can rotate. When the receiving cavity 11 drives the nylon brush 10 to move to the bottom end of the upper mold 21, the nylon brush 10 can The impurities and debris on the surface are swept away and fall down, and the receiving cavity 11 is located below the nylon brush 10, so that the fallen impurities and debris can be received. When the displacement cross plate 20 moves upward to the limit position, the first gear 7 can completely pass through the fourth rack 33, so that the first gear 7 will lose the engagement force. At this time, the elasticity of the first spring 23 will drive the movable bracket 9 to quickly reset, and when the movable bracket 9 is reset, it can move to the bottom of the L-shaped bracket 24, so as to avoid the interference between the receiving cavity 11 and the lower mold 3 when the displacement cross plate 20 moves downward again. At the same time, when the movable bracket 9 is reset, it can drive the nylon brush 10 to pass the bottom end of the upper mold 21 again, and the upper mold 21 can be cleaned again, thereby improving the surface cleaning efficiency of the upper mold 21. Then, the driving mechanism is turned on again. When the dynamic system drives the displacement cross plate 20 to move downward and is about to move to the limit position, the elasticity of the second spring 31 will drive the contact cavity 27 to extend upward, so that the receiving cavity 11 can contact the contact cavity 27 in advance, and when the contact cavity 27 contacts the receiving cavity 11, it can be aligned with the discharge hole at the bottom end of the receiving cavity 11. The setting of the second spring 31 allows the displacement cross plate 20 to continue to displace, driving the contact cavity 27 to move downward. At this time, when the receiving cavity 11 squeezes the contact cavity 27 to move downward, it can drive the counterweight 15 to contact the positioning bottom plate 35. Through the restriction of the positioning bottom plate 35, when the displacement cross plate 20 moves downward, the third gear 14 can simultaneously move downward along the second rack 17, so that when the third gear 14 rotates,It can drive the first rack 16 to move toward one end away from the receiving cavity 11, so that the blocking bottom plate 13 can be displaced from below the discharge hole at the bottom end of the receiving cavity 11. At this time, the impurities and debris inside the receiving cavity 11 can be discharged downward from the inside of the receiving cavity 11 into the inside of the contact cavity 27. The contact cavity 27 is connected with the discharge cavity 29 by the alignment tube 30, so that the impurities and debris are finally discharged outward from the discharge cavity 29, completing the discharge of impurities and debris. When the displacement cross plate 20 is displaced upward and reset again, the receiving cavity 11 can drive the third gear 14 to move upward along the surface of the second rack 17, so that the first rack 16 can be driven to move toward one end close to the receiving cavity 11, thereby The blocking bottom plate 13 can be reset to block the discharge hole at the bottom end of the receiving cavity 11. In addition, the key on the side end of the second rack 17 slides in the slot in the side end of the extension bracket 18, so that the extension bracket 18 can be supported to move downward along the surface of the second rack 17. When the displacement cross plate 20 drives the counterweight block 15 to move out of contact with the positioning bottom plate 35, the setting of the counterweight block 15 can always drive the second rack 17 in a downward posture, thereby preventing the blocking bottom plate 13 from moving prematurely. At the same time, when the displacement cross plate 20 resets upward, the second spring 31 can drive the contact cavity 27 to move upward and reset, so that the contact cavity 27 can contact the receiving cavity 11 again, completing the work. Example 2

[0029] On the basis of Example 1, Figure 8 As shown, the punching machine 32 further includes a receiving drawer 36 and a guide rail 37 . The guide rail 37 is symmetrically fixedly mounted at the front end of the punching machine 32 , and the receiving drawer 36 is slidably mounted on the top end of the guide rail 37 .

[0030] When implementing this embodiment, the receiving drawer 36 is vertically aligned with the bottom end of the discharge cavity 29, so that the debris and impurities discharged outward from the discharge cavity 29 can fall into the interior of the receiving drawer 36 for collection. When the receiving drawer 36 accumulates a certain amount of debris and impurities, the receiving drawer 36 can be pulled toward the end away from the punching machine 32 until it is removed from the guide rail 37, so as to facilitate the dumping of the impurities and debris inside the receiving drawer 36. Subsequently, the receiving drawer 36 is moved again and inserted into the guide rail 37 until the receiving drawer 36 is in contact with the punching machine 32, thereby completing the installation of the receiving drawer 36.
