Description

Technical Field

[0001] This utility model relates to the technical field of sealing, and in particular to a can sealing machine. Background Technology

[0002] A can sealing film machine is a device that adds a label film to the top of a sealed can. It is mainly used to prevent secondary contamination. After filling and before leaving the factory, a protective film is applied to the pull ring and top cover of the can to avoid dust and bacterial contamination during transportation and storage. It also enhances the product's image: cans with the film appear more hygienic and high-end, and are commonly found in high-end beverages, functional beverages, and gift packaging. Furthermore, it provides anti-counterfeiting and anti-opening features; some films have anti-counterfeiting labels or are designed to be irreversible once opened.

The other end of the synchronizing rods 67 is fixed on the inner side of the rotating frame 64. By fixing the main shaft 552 and the sleeve rod 562 to each other, the main shaft 552 drives the sleeve rod 562 to rotate synchronously when it rotates. The rotation of the sleeve rod 562 drives the drive platform 561 and the second support base 56 to rotate. The rotation of the second support base 56 drives the turntable 51 to rotate. The synchronizing rods 67 are mounted on the main shaft 552.

[0030] Please see Figures 1-7 Multiple lifting seats 63 are vertically arranged on the top surface of the rotating frame 64. The number of lifting seats 63 corresponds to the number of first connecting plates 52. The center of the lifting seat 63 coincides with the center of the first connecting plate 52. The lifting seat 63 is "C" shaped. A slider 638 is arranged at the center of the back of the lifting seat 63. The top surface of the slider 638 is in contact with the bottom surface of the upper rail 661. The diameter of the slider 638 is the same as the distance between the upper rail 661 and the lower rail 662. The rotation of the rotating frame 64 drives the lifting seat 63 to rotate. The slider 638 is arranged on the lifting seat 63 so that when the lifting seat 63 passes between the upper rail 661 and the lower rail 662, it follows the track between the upper rail 661 and the lower rail 662 and undulates.

[0031] Please see Figures 1-7A pair of lifting rods 632 are symmetrically arranged on the lifting seat 63. A first reset seat 631 is provided on the outer side of the lifting rod 632.

Each lifting seat 63 has a connecting piece 634 attached to the top surface of a pair of lifting rods 632. A second reset seat 635 is located at the center between the lifting rods 632 of the lifting seat 63. The top end of the second reset seat 635 penetrates the top surface of the lifting seat 63 and is fixed to the outer side of the top surface of the lifting seat 63. A pressure rod 637 is located on the inner side of the second reset seat 635, and a second reset spring 636 is located on the outer side of the pressure rod 637. The two ends of the second reset spring 636 are fixed between the second reset seats 635. The other end passes through the rotating frame 64. A pressure bar 637 is positioned below the rotating frame 64, with a pressure platform 65. The center of the pressure platform 65 coincides with the center of the first connecting plate 52. A pair of lifting rods 632 are fixed at the bottom of the rotating frame 64, and at the top by connecting pieces 634. The lifting seat 63 remains vertical as it moves along the track between the upper rail 661 and the lower rail 662. The first reset seat 631 and the first reset spring 633 quickly reset the lifting seat 63 after it moves off the track. 3. During the lifting process, the pressure rod 637 is driven to lift synchronously. The second return spring 636 and the second return seat 635 enhance the downward force of the pressure rod 637 during the descent of the lifting seat 63. During the movement, the pressure rod 637 pushes the pressure table 65 to press the label on the top of the can on the first connecting plate 52. The two ends of the upper rail 661 are located above the bottle inlet star wheel 41 and the bottle outlet star wheel 42, respectively, so that the lifting seat 63 only rises at the point directly between the bottle inlet star wheel 41 and the bottle outlet star wheel 42, thereby increasing the pressing time of the pressure table 65.

[0032] Please see Figures 1-7The output wheel 71 has two meshing intermediate wheels 72 on both sides, and the top of the intermediate wheels 72 is fixed to the inner top surface of the drive base 12. A pair of first gears 43 mesh on the outer side of the intermediate wheels 72. The pair of first gears 43 are coaxially arranged with the inlet star wheel 41 and the outlet star wheel 42. A synchronous wheel 46 is coaxially arranged on the top surface of the first gear 43, and a first drive shaft 47 is coaxially arranged at the other end of the synchronous wheel 46. The other ends of the pair of first drive shafts 47 pass through the top surface of the drive base 12 and are respectively connected to the bottom of the inlet star wheel 41 and the outlet star wheel 42. A star wheel support 44 is coaxially arranged on the top surface of the drive base 12 outside the first drive shaft 47. A star wheel support rod 45 is coaxially arranged on the top of the star wheel support 44. A bearing seat 48 is coaxially arranged on the top of the star wheel support rod 45. A bearing 49 is arranged on the top surface of the bearing seat 48, and the top end of the first drive shaft 47 passes through the bearing 49. The output wheel... Simultaneously, 71 drives two intermediate wheels 72 to rotate, which in turn drives the first gears 43 on both sides to rotate, causing the synchronous wheel 46 and the first drive shaft 47 to rotate synchronously. Through the rotation of the two first drive shafts 47, the bottle inlet star wheel 41 and the bottle outlet star wheel 42 are driven to rotate. Through the rotation of the bottle inlet star wheel 41 and the bottle outlet star wheel 42, the bottle inlet star wheel 41 carries the unsealed can to the first connecting plate 52. After the pressure table 65 seals the label on the top of the can on the first connecting plate 52, the turntable 51 rotates to transfer the sealed can to the bottle outlet star wheel 42. The bottle outlet star wheel 42 rotates to export the sealed can. The first drive shaft 47 is kept vertical by the star wheel support 44 and the star wheel support rod 45. The bearing 49 is supported by the bearing seat 48. The bearing 49 allows the first drive shaft 47 to rotate independently of the star wheel support 44 and the star wheel support rod 45.

[0033] Please see Figures 1-7 A lifting platform 58 is provided below the second gear 55, and a lead screw motor 57 is provided on the top surface of the second support base 56. A lead screw 571 is provided on the top of the lead screw motor 57. The lead screw 571 is coaxially arranged with the main shaft 552 and passes through the main shaft 552. The top end of the lead screw 571 is connected to the top of the sealing platform 66. The two ends of the lead screw 571 are fixed by the lead screw motor 57 and the sealing platform 66 and are located inside the main shaft 552. The lead screw motor 57 is supported by the lifting platform 58.

[0034] During use, the finished aluminum can is transferred from the inlet screw 21 to the inlet star wheel 41. The labeling component 31 above the inlet star wheel 41 presses the label with adhesive onto the top of the aluminum can to complete the labeling action. The inlet star wheel 41 transfers the aluminum can to the first connecting plate 52. While the turntable 51 drives the aluminum can on the first connecting plate 52 to rotate, the rotating frame 64 rotates synchronously with the first connecting plate 52. When the rotating frame 64 rotates, the lifting seat 63 on the rotating frame 64 is raised at the upper rail 661 and lower rail 662 to facilitate the aluminum can entering the turntable 51. After the lifting seat 63 moves out of the upper rail 661 and lower rail 662, the lifting seat 63 drives the pressure rod 637 to move downward. The pressure table 65 on the pressure rod 637 presses the label on the aluminum can. When the aluminum can rotates with the turntable 51 into the outlet star wheel 42, the lifting seat 63 drives the pressure table 65 to lift, and the outlet star wheel 42 ejects the aluminum can.
