It combines the characteristics of electric drive and semi-automatic operation, and can efficiently complete the sealing of canned products. Its working process is generally to place the can with a lid on the bottom support, and then raise the bottom support until the lid on the can is tightly pressed against the pressure head on the screw capping structure. At this time, under the action of the pressure head, the lid and the can are fixed, and then the lid is sealed by the rotating capping roller on the screw capping structure to complete the sealing.

[0003] Different cans or beverage bottles have different diameters and sizes. The size of the pressure head needs to be selected according to the diameter of the can. When changing to a can of a different size for sealing, the pressure head of the corresponding size needs to be replaced to ensure that the pressure head can accurately fix the position of the can body and the can lid. The pressure head is generally connected by bolts and is inconvenient to disassemble. After replacing the pressure head, the corresponding capping roller can be replaced. In addition, the bottom support on the existing capping machine also needs to be replaced according to different can bodies, which is inconvenient to operate.

[0004] In view of this, a capping structure of a capping machine with strong adaptability is proposed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figures 1-8 As shown, a capping structure of a capping machine with strong adaptability includes a square base 1 and supporting legs 2 fixedly connected to the four corners of the square base 1 with anti-slip pads, the top of the square base 1 is fixedly connected to a mounting platform 3, the top of the mounting platform 3 is fixed with a power box 4 through two L-shaped support rods, the bottom of one end of the power box 4 is connected to a capping device 5, the bottom of the capping device 5 is provided with an adjustable diameter can cover press head assembly 6, the top of the mounting platform 3 is provided with a switchable lifting integrated can placement assembly 7, and the switchable lifting integrated can placement assembly 7 is located below the adjustable diameter can cover press head assembly 6.

[0027] The square base 1 provides a stable supporting foundation, while the supporting legs 2 with anti-slip pads at the four corners further enhance the stability of the equipment to prevent movement or tipping due to vibration or external force during operation. The two L-shaped support rods are symmetrically arranged, which not only ensures a stable structure but also effectively supports the power box 4. The power box 4 is one of the core components of the capping machine and is responsible for providing the power required for capping. The capping device 5 connected to its bottom directly performs the capping action and realizes the tight screwing of the can lid through precise mechanical transmission.

[0028] The adjustable diameter tank cover pressure head assembly 6 includes a circular connecting plate 601, which is connected to the screw cap device 5 by a fixing bolt 602. The bottom of the circular connecting plate (601) is fixedly connected to a rectangular plate 603. The bottom of the rectangular plate 603 is installed with a first fixed tank cover pressure head 604. The rectangular plate 603 is provided with a first rectangular through hole and a second rectangular through hole from left to right. A first U-shaped plate 605 is slidably connected in the first rectangular through hole. The two ends of the first U-shaped plate 605 are fixed with an inner adjustment ring 606. The inner adjustment ring 606 is located at the first A second U-shaped plate 607 is slidably engaged with the outer side of a fixed tank cover pressure head 604 in the second rectangular through hole, and outer adjustment rings 608 are fixed at both ends of the second U-shaped plate 607. The outer adjustment ring 608 is located on the outer side of the inner adjustment ring 606. Threaded holes are provided on the first U-shaped plate 605 and the second U-shaped plate 607. A driving motor 609 is fixedly connected to the inner side wall of the top of the first rectangular through hole and the inner side wall of the top of the second rectangular through hole. The output shaft of the driving motor 609 is connected to a driving screw 610, and one end of the driving screw 610 is passed through the threaded hole.

[0029] When the outer adjustment ring 608, the inner adjustment ring 606 and the first fixed capping pressure head do not move, the three can form a relatively large pressure head. The number of the driving motor 609 and the driving screw 610 are both two. When one driving motor 609 drives the driving screw 610 to work, it can drive the second U-shaped plate 607 to rise in the second rectangular through hole, so that the second U-shaped plate 607 can drive the outer adjustment ring 608 to rise. At this time, the inner adjustment ring 606 and the first fixed capping pressure head can form a relatively small pressure head. The method of rising the inner adjustment ring 606 is the same as that of the outer adjustment ring 608. After the inner adjustment ring 606 rises, the first fixed capping pressure head can be used alone, so that pressure heads of different diameters can be replaced according to cans of different diameters, and the adaptability is strong. In addition, when the diameter of the pressure head changes, the user needs to replace the capping roller on the screw capping device 5. It is worth mentioning that the adjustable diameter can cover pressure head assembly 6 can also be replaced as a whole through the fixing bolt 602.

[0030] Example 2

[0031] The switchable lifting integrated can placement component 7 includes a bottom ring 701 connected to the top of the mounting platform 3, the top of the bottom ring 701 is rotatably clamped with a gear ring 702, the top of the gear ring 702 is fixedly installed with a telescopic sleeve 703 in a circumferential array, one end of the telescopic sleeve 703 is fixedly installed with a can placement disc 704, the top of the can placement disc 704 is provided with can placement grooves 705 of different diameters in a circumferential array, an electric telescopic rod 706 is fixedly installed on the top of the mounting platform 3, and one end of the electric telescopic rod 706 is rotatably clamped on the can placement disc 704, and a rotating motor 707 is fixed on the top of the mounting platform 3. A rotating gear 708 is fixedly connected to the output end of the rotating motor 707, and the rotating gear 708 is engaged with the gear ring 702. After the rotating motor 707 is working, it can drive the rotating gear 708 and the gear ring 702 to rotate. The rotation of the gear ring 702 can drive the telescopic sleeve rod 703 and the can placement disc 704 to rotate. Since the can placement disc 704 and the electric telescopic rod 706 are rotatably connected, the rotation of the can placement disc 704 will not affect the electric telescopic rod 706. After the can placement disc 704 rotates, the position of the can placement groove 705 changes relatively, thereby achieving the switching function without the need for replacement.

[0032] When the present invention is in use, when sealing a jar, the user can first place the jar in the jar placement groove 705 on the jar placement disc 704, and put a lid on the top of the jar. When the electric telescopic rod 706 works, it can drive the jar placement disc 704 and the jar to rise. When the jar placement disc 704 rises, it will drive the telescopic end of the telescopic sleeve rod 703 to rise. Because the bottom of the telescopic sleeve rod 703 is fixed to the gear ring 702, and the gear ring 702 is rotated and clamped on the bottom ring 701, when the lid on the jar is tightly pressed against the pressure head composed of the outer adjustment ring 608, the inner adjustment ring 606 and the first fixed filling and covering pressure head, the jar and the lid are in a fixed state. When the capping roller on the rotating device rotates, the sealing of the lid can be completed.
