[0047] A support plate 56 is fixedly connected to one side of the frame 1, and a cylinder 59 is rotatably connected to the top of the support plate 56. A first rotating shaft 16 is slidably penetrated inside the cylinder 59. A blanking assembly for blanking the belt is arranged on the top of the first rotating shaft 16. The blanking assembly includes a strip box 2 fixedly connected to the top of the first rotating shaft 16, and a plurality of hollow cylinders 15 are fixedly connected to the bottom of the strip box 2.

The eccentric rod 50 moves inside the arc-shaped hole 45. When the eccentric rod 50 is above the arc-shaped hole 45, the rectangular plate 12 does not move. When the eccentric rod 50 needs to move downward, it will push the rectangular plate 12 to move downward, and the rectangular plate 12 drives the rotating ring 54 to move downward, and the rotating ring 54 drives the first rotating shaft 16 to move downward.

[0049] In the present invention, an X-shaped groove 57 is provided on one side of the cylinder 59, a first rotating rod 47 is rotatably connected to one side of the frame 1, two symmetrically arranged round rods 49 are fixedly connected to the outer wall of the first rotating rod 47, and the round rods 49 are used in conjunction with the X-shaped groove 57, a notch 55 is provided on one side of the support plate 56, and two symmetrically arranged strip grooves 58 are provided on the inner wall of the cylinder 59, and both sides of the first rotating shaft 16 are fixedly connected to the limiting strips 53, and the limiting strips 53 are used in conjunction with the strip grooves 58, and the outer wall of the second rotating rod 52, the first rotating rod 47 and the third rotating shaft 25 are fixedly connected to the first rotating shaft 16.

At this time, there is a gap between the upper pressure roller 3 and the lower pressure roller 4, which is convenient for the belt to pass through, thereby reducing the workload of the workers and reducing the difficulty of loading. The first mounting plate 20 is reset, and the movable side plate 18 is blocked at one end of the air expansion shaft 7 again to prevent the winding roller from falling off. At the same time, the upper pressure roller 3 and the lower pressure roller 4 clamp the belt.

[0051] A conveyor belt automatic punching method specifically comprises the following steps:

[0052] S1. Sleeve the winding roller on the outer wall of the air expansion shaft 7, stagger the upper pressure roller 3 and the lower pressure roller 4, and pass one end of the belt through the gap between the upper pressure roller 3 and the lower pressure roller 4 to facilitate the feeding of the belt;

[0053] S2, punching the belt with multiple punching blocks 11, rotating 180 degrees after punching, using multiple punching blocks 11 alternately, and introducing air into the air inlet pipe 17 to help discharge the finished product;

[0054] S3. The upper clamping plate 14 and the rectangular box 42 can push the belt forward, thereby realizing the continuous blanking process of the belt.

[0055] Working principle: When it is necessary to punch out the waste belt, the winding roller with the belt wound around it can be installed on the air expansion shaft 7, the braking state of the first mounting plate 20 can be released first, and the pull plate 32 can be moved vertically upward. The pull plate 32 drives the vertical rod 30 to move vertically upward and stretch the tension spring 31. At this time, the vertical rod 30 is moved out from one of the slots 35, and the braking state of the first mounting plate 20 is released;

[0056] The first mounting plate 20 is moved laterally, and the first mounting plate 20 drives the slider 34 to move inside the groove 27, and the vertical rod 30 is inserted into another slot 35 again. At this time, the first mounting plate 20 drives the plurality of second mounting plates 29 to move laterally through the second connecting rod 28, so that the lower pressure roller 4 and the upper pressure roller 3 are staggered. At the same time, the first mounting plate 20 drives the movable side plate 18 to move laterally through the first connecting rod 19, and the movable side plate 18 no longer blocks one end of the air expansion shaft 7;

[0057] The winding roller can be placed on the air expansion shaft 7 and clamped by the air expansion shaft 7, and one end of the belt can be taken out and passed between the two upper pressure rollers 3 and the two lower pressure rollers 4. At this time, there is a gap between the upper pressure roller 3 and the lower pressure roller 4, which is convenient for the belt to pass through, thereby reducing the workload of workers and the difficulty of loading. The first mounting plate 20 is reset, and the movable side plate 18 is blocked at one end of the air expansion shaft 7 again to prevent the winding roller from falling off. At the same time, the upper pressure roller 3 and the lower pressure roller 4 clamp the belt;

[0058] The servo motor 36 is started, and the output shaft of the servo motor 36 drives the second rotating rod 52 to rotate, the second rotating rod 52 drives the rotating plate 51 to rotate, the rotating plate 51 drives the eccentric rod 50 to rotate, the eccentric rod 50 moves inside the arc hole 45, when the eccentric rod 50 is above the arc hole 45, the rectangular plate 12 does not move, when the eccentric rod 50 needs to move downward, it pushes the rectangular plate 12 to move downward, the rectangular plate 12 drives the rotating ring 54 to move downward, and the rotating ring 54 drives the first rotating shaft 16 to move downward;

[0059] At this time, the first rotating shaft 16 drives the strip box 2 to move downward, the strip box 2 drives the multiple hollow cylinders 15 to move downward, the hollow cylinders 15 drive the multiple punching blocks 11 to move downward, the punching blocks 11 drive the punching ring 60 to move downward, the punching ring 60 and the punching blocks 11 punch the belt, and the punched product is discharged through the inclined groove 6 and the trapezoidal plate 5, and the rectangular plate 12 moves up again to complete the punching process;

[0060] When the strip box 2 moves to the highest point, the second rotating rod 52 drives the first rotating rod 47 and the third rotating shaft 25 to rotate through the synchronous wheel 48, and the first rotating rod 47 drives the two round rods 49 to rotate. The round rods 49 enter the interior of the X-shaped groove 57 through the notch 55, and then drive the cylinder 59 to rotate 180 degrees, so that the punching blocks 11 on both sides of the first rotating shaft 16 are replaced and used alternately, which facilitates the falling of the finished product and avoids jamming.

[0061] During the rotation of the cylinder 59, the first rotating shaft 16 is driven to rotate through the cooperation of the strip groove 58 and the limiting strip 53, and the first rotating shaft 16 drives the strip box 2 to rotate, and the strip box 2 replaces the multiple punching blocks 11. At the same time, gas is fed through the air inlet pipe 17, and the gas passes through the interior of the strip box 2 into the interior of the multiple hollow cylinders 15, and enters the interior of the cavity 63, and finally sprayed out through the multiple air outlet holes 61, so as to prevent the finished product from being stuck in the interior of the circular groove 62, and ensure the normal progress of the punching process;

[0062] And when the third rotating shaft 25 rotates, it can drive the circular plate 39 to rotate, and the circular plate 39 drives the protrusion 43 to rotate. When the protrusion 43 rotates to the highest point, it first pushes the U-shaped block 41 to move upward, and the U-shaped block 41 drives the rectangular box 42 to contact the bottom of the belt. The upper clamping plate 14 and the rectangular box 42 clamp the two sides of the belt. The protrusion 43 continues to rotate, which can push the U-shaped block 41 to move laterally. The U-shaped block 41 squeezes the second spring 44 and enters the interior of the rectangular box 42. At the same time, the rectangular box 42 drives the U-shaped frame 37 to move laterally, and the U-shaped frame 37 drives the upper clamping plate 14 to move laterally and squeeze the first spring 38, which can transport the belt forward a certain distance to help the normal blanking process.
