[0023] S2: Make the main shaft of the driving motor rotate unidirectionally, so that the first connecting rod rotates, and under the restriction of the third connecting rod, the second connecting rod is periodically swung, and the swing of the second connecting rod will pull the fourth connecting rod and the fifth connecting rod to move. Under the restriction of the first limiting groove and the second limiting groove, and the difference in the connection between the fourth connecting rod and the fifth connecting rod on the third connecting rod, the edge pressing bracket is pressed down first, and the punching block punches later, the rear edge pressing bracket rises first, and the punching block rises later.

The self-locking intermittent transmission mechanism stops conveying leather and self-locks during punching and blanking. When the punching mechanism is lifted, the leather that has not been punched is conveyed and placed at the punching mouth for efficient cyclic punching and blanking. At the same time, the punching mechanism can first press the edge of the leather and fix it before punching, so the punching effect is good. The structure itself does not require a controller or sensor processing to achieve high-speed cyclic feeding of leather materials, punching and blanking, and has a simple structure, low cost, high operating efficiency and low maintenance cost.

4. A shoe upper processing device according to claim 3, characterized in that: The tooth end of the rack (381) faces downward, the tooth end of the toothed block (353) faces upward, and the tooth end of the rack (381) and the toothed block (353) both fit in with the first gear (38).

5. A shoe upper processing device according to claim 3, characterized in that: The self-locking intermittent transmission mechanism (3) also includes an axle seat (382) fixedly connected to the front side of the T-shaped bracket (1); the axle seat (382) is rotatably connected to an auxiliary bracket (383); a torsion spring (384) is in contact between the auxiliary bracket (383) and the axle seat (382); the first gear (38) is connected to a transmission shaft; the transmission shaft is rotatably connected to the axle seat (382); the end of the transmission shaft is transmission-connected to a second gear (385); the center of the auxiliary bracket (383) is rotatably connected to a gear shaft (387); a third gear (386) is fixedly connected to the front side of the gear shaft (387); the third gear (386) is meshed with the second gear (385); and a conveying rubber wheel (39) is fixedly connected to the rear side of the gear shaft (387).

6. A shoe upper processing device according to claim 5, characterized in that: The torsion spring (384) is normally twisted downward, so that the conveying rubber wheel (39) contacts the T-shaped bracket (1).

7. A shoe upper processing device according to claim 1, characterized in that: A stop bar (16) is also arranged transversely on the front side of the bottom of the T-shaped bracket (1), and a stop shaft (17) is also rotatably connected to the bottom of the front side of the T-shaped bracket (1).

8. The shoe upper processing device according to claim 1, characterized in that: The front side and the rear side of the T-shaped bracket (1) are respectively fixedly connected with a front protective cover (18) and a rear protective cover (19).

9. A processing method of a shoe upper processing device, applied to a shoe upper processing device as claimed in any one of claims 3 to 6, characterized in that: The processing method comprises: S1: The leather to be punched is passed through the stop shaft (17) and placed in the stop bar (16) on the T-shaped bracket (1), and abutted between the conveying rubber wheel (39) and the T-shaped bracket (1); S2: The main shaft of the driving motor (13) is rotated in one direction, so that the first connecting rod (251) rotates. Under the restriction of the third connecting rod (253), the second connecting rod (252) is periodically swung. The swing of the second connecting rod (252) pulls the fourth connecting rod (254) and the fifth connecting rod (255) to move. Under the restriction of the first limiting groove and the second limiting groove, and the difference in the connection between the fourth connecting rod (254) and the fifth connecting rod (255) on the third connecting rod (253), the edge holding bracket (28) is pressed down first, and the punching block (29) is punched later. The rear edge holding bracket (28) rises first, and the punching block (29) rises later. After the punching is completed, The running section (312) in the cam groove (311) is also in contact with the rotating shaft (314), so that the swing rod (33) pushes the movable plate (35) to move downward in the two limit blocks (34) through the matching block (37). At this time, the tooth block (353) is not in contact with the first gear (38), and the lifting block (36) also drives the rack (381) to contact the first gear (38), and the rack (381) drives the first gear (38) to rotate, and finally the first gear (38) drives the second gear (385) to drive the first gear (38) to rotate through the transmission shaft, so that the first gear (38) drives the conveying rubber wheel (39) to rotate, thereby dragging the leather to be fed; S3: During the punching stage, the stop section (313) in the cam groove (311) also contacts the rotating shaft (314). Similarly, the rocker arm (33) pushes the movable plate (35) to move upward between the two limit blocks (34) through the matching block (37). At this time, the toothed block (353) contacts the first gear (38), and the lifting block (36) also drives the rack (381) to rise and reset. At this time, the first gear (38) is limited and does not rotate, so it will not drag the leather during punching.
