A first support plate 3 is fixedly connected to the top of the first connecting plate 10, and a second support plate 8 is fixedly connected to one end of the top of the first connecting plate 10 away from the first support plate 3. A first rotating plate 6 is rotatably connected to the side of the second support plate 8 close to the first support plate 3. A bearing is arranged between one side of the first rotating plate 6 and the second support plate 8 to make the rotation of the first rotating plate 6 more smooth. A second rotating plate 7 is rotatably connected to the side of the first support plate 3 close to the second support plate 8. A bearing is arranged between one side of the second rotating plate 7 and the first support plate 3 to make the rotation of the second rotating plate 7 more smooth. U-shaped plates 16 are fixedly connected to both the side of the second rotating plate 7 away from the first support plate 3 and the side of the first rotating plate 6 away from the second support plate 8. The second rotating plate 7 rotates to drive the U-shaped plate 16 to rotate. A winding rod 5 is detachably connected inside the U-shaped plate 16. The U-shaped plate 16 rotates to drive the winding rod 5 to rotate. The winding rod 5 rotates to drive the first rotating plate 6 to rotate. Second connection holes 13 are opened at both ends of one side of the winding rod 5, and first connection holes 12 are opened at both ends of the side of the winding rod 5 away from the second connection holes 13. A first connection column 17 is fixedly connected inside the U-shaped plate 16. The first connection column 17 enters the second connection hole 13 to limit the moving position of the winding rod 5 in the U-shaped plate 16. A baffle 18 is rotatably connected to one side of the U-shaped plate 16 to better fix the winding rod 5 inside the U-shaped plate 16. A second connection column 19 is slidably connected inside the baffle 18. The second connection column 19 enters the first connection hole 12 to make the U-shaped plate 16 rotate to drive the winding rod 5 to rotate. A card hole 22 is opened at one end of the bottom of the baffle 18. A card block 21 is slidably connected inside the U-shaped plate 16. The card block 21 enters the card hole 22 to connect the baffle 18 and the U-shaped plate 16 and fix the winding rod 5 inside the U-shaped plate 16. A handle is fixedly connected to the top of the baffle 18 to better move the baffle 18. A third support plate 9 is fixedly connected to one end of the top of the base 1. There are two groups of the third support plates 9. A guide roller 31 is rotatably connected between the two groups of the third support plates 9. A first pneumatic rotating shaft 14 is arranged on one side of the third support plate 9. One end of the guide roller 31 passes through one side of the third support plate 9 and is fixedly connected to the first pneumatic rotating shaft 14. When the first pneumatic rotating shaft 14 is started, it drives the guide roller 31 to rotate. The rotation of the guide roller 31 makes the movement of the material on its surface more smooth. The first pneumatic rotating shaft 14 includes: a pneumatic impeller and an air flow control pipeline. The pneumatic impeller rotates to drive the guide roller 31 to rotate. The air outlet of the air flow control pipeline is aligned with the pneumatic impeller, and the air flow coming out of the air outlet drives the pneumatic impeller to rotate.

[0026] Furthermore, a second limiting plate 28 is fixedly connected to the outer side of the second connecting column 19, and a second spring 29 is fixedly connected between the bottom of the second limiting plate 28 and the baffle 18. The second connecting column 19 moves into the first connecting hole 12 with the second limiting plate 28, and the second limiting plate 28 moves to squeeze the second spring 29. When the second spring 29 loses its pressing force, under the action of elastic force, the second spring 29 restores the second connecting column 19 to its original position through the second limiting plate 28. The top of the second connecting column 19 is fixedly connected to a second connecting plate 20, and the second connecting plate 20 moves with the second connecting column 19. The second connecting plate 20 is detachably connected to the second connecting plate 20 by a second bolt 30, and the position of the second connecting plate 20 is fixed, thereby fixing the second connecting column 19 in the first connecting hole 12.

When the baffle 18 moves, the card hole 22 squeezes the block 21, and the block 21 moves. The block 21 moves and moves with the first limit plate 23 along the sliding rod 24. A first spring 25 is fixedly connected between one side of the first limit plate 23 and the U-shaped plate 16. The movement of the first limit plate 23 squeezes the first spring 25, and the first spring 25 is squeezed to generate elastic force. When the first spring 25 loses its pressing force, under the action of the elastic force, the first spring 25 restores the block 21 to its original position through the first limit plate 23.

[0028] Furthermore, one end of the clamping block 21 is fixedly connected to a third connecting plate 26, and the third connecting plate 26 moves with the clamping block 21. The third connecting plate 26 is detachably connected to the U-shaped plate 16 via a first bolt 27. By fixing the position of the third connecting plate 26, the position of the clamping block 21 is also fixed to prevent the clamping block 21 from escaping from the clamping hole 22 during use.

[0029] Furthermore, a motor 4 is fixedly connected to one side of the first support plate 3 , and an output end of the motor 4 passes through one side of the first support plate 3 and is fixedly connected to the second rotating plate 7 . When the motor 4 is turned on, the motor 4 rotates the second rotating plate 7 .

[0030] Furthermore, a control panel 15 is provided on one side of the second support plate 8, and the motor 4, the first pneumatic shaft 14 and the weight sensor 11 are all electrically connected to the control panel 15 to better control the entire device.

The rotation of the second rotating plate 7 drives the U-shaped plate 16 to rotate. The U-shaped plate 16 drives the winding rod 5 to rotate to wind the material. After the first pneumatic rotating shaft 14 is turned on, it drives the guide roller 31 to rotate, making the movement of the material smoother. The weight sensor 11 transmits the weight data of the material on the surface of the winding rod 5 to the control panel 15. When the material weight reaches a certain value, the control panel 15 controls the motor 4 and the first pneumatic rotating shaft 14 to turn off, stopping the winding of the material. Rotate the second bolt 30 to loosen the connection between the second connecting plate 20 and the baffle 18. The second spring 29 loses the pressing force. Under the action of the elastic force, the second spring 29 drives the second connecting column 19 and the second connecting plate 20 to return to their original positions through the second limiting plate 28. The second connecting column 19 moves out of the first connecting hole 12. Rotate the first bolt 27 to loosen the connection between the third connecting plate 26 and the U-shaped plate 16. Move the third connecting plate 26. The third connecting plate 26 drives the clamping block 21 to move. The clamping block 21 moves away from one side of the clamping hole 22, releasing the restriction on the baffle 18. Hold the handle and move the baffle 18 away from one side of the U-shaped plate 16. Remove the material together with the winding rod 5 from the U-shaped plate 16 to complete the blanking operation of the product.
