[0019] Example: Figure 1-6As shown, this utility model provides a can lid rolling device, including a workbench 1 and a rolling mechanism 3. The rolling mechanism 3 is disposed on the workbench 1 and includes a fixing plate 31, which is fixedly installed on the workbench 1. A lifting plate 32 is slidably disposed inside the fixing plate 31. A cylinder 33 is installed at the top of the fixing plate 31, and the driving end of the cylinder 33 is fixedly connected to one end of the lifting plate 32. A connecting plate 34 is rotatably installed at the end of the lifting plate 32 away from the fixing plate 31. A first mold 35 and a second mold 36 are symmetrically distributed and rotatably installed on the lower surface of the connecting plate 34. The first mold 35 and the second mold 36 are detachable. A drive motor 37 is fixedly mounted on the upper surface. The end of the output shaft of the drive motor 37 is fixedly connected to the connecting plate 34. A connecting rod 38 is rotatably mounted on the lower surface of the connecting plate 34. A support column 39 is slidably mounted inside the connecting rod 38. A second spring 310 is fixedly mounted inside the connecting rod 38. One end of the second spring 310 is fixedly connected to the top end of the support column 39. A turntable 5 is mounted on the upper surface of the worktable 1. A transfer plate 6 arranged in a ring array is fixedly mounted on the upper surface of the turntable 5. A ring cover 7 is fixedly mounted on the upper surface of the worktable 1. The ring cover 7 is located outside the turntable 5. A positioning component 2 is mounted inside the transfer plate 6. A pushing component 4 is mounted on the ring cover 7.The positioning component 2 includes a positioning plate 21. A rotating disk 5 has cavities 22 arranged in a circular array. A gear 23 is disposed inside each cavity 22. A mirror-image toothed plate 24 meshes with the outer side of the gear 23. A mirror-image through groove 25 is formed at the top of the inner wall of the cavity 22. A connecting block 26 is slidably disposed inside the through groove 25. The two ends of the connecting block 26 are fixedly connected to one end of the toothed plate 24 and the bottom end of the positioning plate 21, respectively. A knob 27 slides through the middle of the gear 23, driving the gear 23 via the knob 27. Rotation causes gear 23 to drive two toothed plates 24 to move in opposite directions. The toothed plates 24 drive the connecting block 26 to move within the through groove 25. The connecting block 26 drives the positioning plate 21 to move and match with the can. This facilitates the matching of the transfer plate 6 with different cans. The outer side of the annular cover 7 has vertically distributed inlet 11 and outlet 12, which are aligned with the two transfer plates 6. The inlet 11 is symmetrically distributed with the edge-rolling mechanism 3. The inlet 11 and outlet 12 can be used to easily control the can. The can inlet and outlet transfer plate 6 has a second rotating shaft 8 fixedly passing through the middle of the turntable 5. The bottom end of the second rotating shaft 8 is rotatably mounted on the workbench 1. A motor 9 is fixedly installed at the bottom end of the workbench 1. The end of the output shaft of the motor 9 movably passes through the workbench 1 and is fixedly connected to the bottom end of the second rotating shaft 8. The rotation of the second rotating shaft 8 can drive the turntable 5 to rotate. The motor 9 provides power for the rotation of the second rotating shaft 8. A groove 28 is opened at the bottom of the cavity 22. A locking block 29 is slidably installed inside the groove 28. The lower surface of the gear 23 is opened with A slot 211 is provided, and a locking block 29 is slidably locked within the slot 211. The bottom end of a knob 27 is rotatably mounted on the upper surface of the locking block 29. The gear 23 can be fixed by locking the locking block 29 into the slot 211. A first spring 210 is fixedly installed inside the groove 28. One end of the first spring 210 is fixedly connected to the lower surface of the locking block 29. The elastic force of the first spring 210 can drive the locking block 29 to reset. A baffle 13 is fixedly installed between the transfer plates 6 to prevent the aluminum can from moving between the two transfer plates 6.

[0020] The feeding assembly 4 includes a support plate 41, one end of which is fixedly mounted on the top of the annular cover 7. A groove 42 is provided on the outer side of the support plate 41, and a slider 43 is slidably mounted inside the groove 42. An L-shaped push rod 44 is fixedly mounted on one side of the slider 43. An electric telescopic rod 45 is fixedly mounted on one end of the support plate 41. The telescopic end of the electric telescopic rod 45 passes through the support plate 41 and is fixedly connected to one side of the slider 43. The electric telescopic rod 45 drives the slider 43 to move within the groove 42, and the slider 43 drives the L-shaped push rod 44 to move, so that the L-shaped push rod 44 pushes the can out of the transfer plate 6. This makes it easy to push the can out. A feeding groove 10 is provided at the end of the transfer plate 6 away from the annular cover 7. The feeding groove 10 is aligned with the L-shaped push rod 44, and the feeding groove 10 allows the L-shaped push rod 44 to pass through and push the material.

[0021] Working principle: When different outer diameter can lids are needed, the knob 27 is moved downwards using a tool. The knob 27 moves the locking block 29 out of the slot 211 and into the groove 28, compressing the first spring 210. This causes the first spring 210 to generate elastic force. Then, the knob 27 is rotated, causing the gear 23 to rotate. This causes the gear 23 to move the two toothed plates 24 in opposite directions. The toothed plates 24 move the connecting block 26 in the through groove 25. The connecting block 26 moves the positioning plate 21, thereby adjusting the distance between the two positioning plates 21 to match the can. At the same time, the slot 211 and the locking block 29 are aligned. The first spring 210 uses its elastic force to reset the locking block 29. The locking block 29 then engages in the slot 211 to fix the gear 23. This makes it easy for the transfer plate 6 to match cans with different outer diameters.

[0022] When sealing the cans, an external conveying mechanism moves the cans with lids already placed on them from the inlet 11 to the turntable 5 and into the transfer plate 6, where they fit against the positioning plate 21. Then, the motor 9 is started, causing its output shaft to drive the second rotating shaft 8 to rotate. The second rotating shaft 8 then drives the turntable 5 to rotate intermittently, aligning the transfer plate 6 with the inlet 11 sequentially. Simultaneously, the cans enter the transfer plate 6 sequentially, aligning them with the support column 39. The cylinder 33 is then activated, its drive end moving the lifting plate 32 downwards. The lifting plate 32 moves the support column 39 downwards, securing it into the can lid. Finally, the drive motor 37 is activated, its output shaft driving the connecting plate 34 to rotate. The connecting plate 34 then drives the first mold 35 and the second mold 36 to rotate at high speed. The lifting plate 32 moves downwards via the connecting plate 34, driving the first mold 35 and the second mold 36 to continue moving. The first mold 35 first mechanically extrudes the connection between the can and the cap to form the first layer of rolled edge. Then, the second mold 36 continues to move and mechanically extrudes the connection between the can and the cap to form the second layer of rolled edge. This can roll and seal the can. Then, the transfer plate 6 moves the sealed can to align with the discharge port 12. Then, the electric telescopic rod 45 is activated, causing the electric telescopic rod 45 to start working. The electric telescopic rod 45 drives the slider 43 to move in the slide 42. The slider 43 drives the L-shaped push rod 44 to move, so that the L-shaped push rod 44 passes through the push groove 10 and pushes the can out of the transfer plate 6, so that the can moves from the discharge port 12 to the external conveying mechanism. This makes it easy to push the can out.
