Description

Technical Field

[0001] This utility model relates to the field of filling and packaging technology, specifically to an automatic synchronous capping machine for capping packaging cans. Background Technology

[0002] In the pharmaceutical and food industries, various pills, milk powder, beverages, condiments, seasonings, tea, coffee, and other items are usually packaged in cans for convenient transportation and storage. To ensure the contents of the cans are sealed, can lids are used to cover the cans.

[0003] Existing manufacturers typically use a capping structure to press the can lid onto the can body. For example, Chinese patent CN219928011U, "Capping Discharge Conveying Device," discloses a capping discharge conveying device, including a can rotating disc and an upper can conveyor belt. A capping device is located on one side of the rotating disc, and a discharge conveyor belt is located on another side. A discharge baffle is located at the front end of the discharge conveyor belt. A discharge pusher, activated by a cylinder, swings back and forth between the discharge conveyor belt and the discharge end of the rotating disc. Arc-shaped baffles are located around the rotating disc. However, existing capping structures have the following shortcomings in use:

[0004] To improve the sealing of the packaging cans, some cans have a can-shaped lid, as shown in the attached diagram in the instruction manual. Figure 1 As shown, during the capping process of this type of packaging can, the can lid needs to be pressed to the bottom of the can. However, the existing capping structure is affected by the rotating plate. Because of the rotating plate, when the can lid cannot be pressed to the bottom of the can, it is necessary to manually press the can lid to the bottom of the can after the can is transported out by the discharge conveyor belt. This affects the capping efficiency of the can and requires a large amount of manual labor, resulting in high labor costs. It is not suitable for large-scale can capping and packaging.

[0035] like Figures 2-7 As shown, Embodiment 1 of this utility model provides an automatic synchronous capping machine for packaging cans. The automatic synchronous capping machine includes a frame 1 and a cap suction and feeding structure 2, a can cap conveying structure 3 for conveying can caps 8, a can body rotating structure 4 for conveying can bodies 9, a multi-station can cap pressing structure 5, a synchronous capping structure 6, and a can body conveying structure 7 installed on the frame 1. The can body rotating structure 4 is installed on one side of the middle of the can body conveying structure 7, and the synchronous capping structure 6 is installed on the other side of the can body conveying structure 7 and located on one side of the can body rotating structure 4. The can cap conveying structure 3 and the can body conveying structure 7 are distributed at intervals and installed below the cap suction and feeding structure 2. The cap suction and feeding structure 2 is installed above the can body rotating structure 4, and the multi-station can cap pressing structure 5 is installed above the can body rotating structure 4. The cap suction and feeding structure 2 is located on one side of the multi-station can cap pressing structure 5. The automatic synchronous capping machine of this invention uses a cap conveying structure 3 to transport can caps 8 to below a cap suction and delivery structure 2. The cap suction and delivery structure 2 picks up the can caps 8 and delivers them onto the can body 9 of a can rotating structure 4 below. The can body rotating structure 4 then delivers the can body 9 with the cap to a multi-station can cap pressing structure 5. The multi-station can cap pressing structure 5 presses down the can caps 8 on the can body 9. After being pressed down, the can caps 8 and the can body 9 are conveyed together to a can conveying structure 7 under the rotation of the can rotating structure 4. The synchronous capping structure 6 on the other side of the can conveying structure 7 continues to press down the cans. The automatic synchronous capping machine of this invention is equipped with a synchronous capping structure 6, which can press the can lid 8 down to the bottom of the can body 9. This solves the technical problems of traditional capping equipment, such as the inability to press the can lid 8 down to the bottom of the can body 9, the need for additional manual capping, and the impact on capping processing efficiency. The automatic synchronous capping machine of this invention can realize the full automation of the capping operation process, improve the capping efficiency of the can body 9, reduce the labor intensity of workers, reduce labor costs, and improve the processing efficiency of the can body 9. It is suitable for large-scale can body 9 capping processing and production.

The capping lifting mechanism 63 is located on one side of the capping vertical plate 61 and connected to the capping vertical plate 61. The plurality of synchronous capping wheels 62 are installed below the capping lifting mechanism 63. The capping driving mechanism 64 is located above the plurality of synchronous capping wheels 62 and is drively connected to the plurality of synchronous capping wheels 62. The capping lifting mechanism 63 drives the capping vertical plate 61 and the plurality of synchronous capping wheels 62 on the capping vertical plate 61 and the capping driving mechanism 64 to move up and down as a whole, so that the plurality of synchronous capping wheels 62 move downward as a whole, so that the plurality of synchronous capping wheels 62 completely press the can lid 8 on the can conveying structure 7 down to the bottom of the can 9. In specific implementation, the synchronous capping structure 6 of this utility model includes a connecting plate 65, which is disposed on the opposite side of the capping vertical plate 61.

The cylinder piston rod of the capping lifting cylinder 632 is connected to the top of the lifting linkage plate 633. The side of the lifting linkage plate 633 is fixed to the side of the capping vertical plate 61. The piston rod of the cap-pressing lifting cylinder 632 drives the lifting linkage plate 633 to move up and down, causing the lifting linkage plate 633 to drive the cap-pressing vertical plate 61 shaft and the entire cap-pressing drive mechanism 64 to move up and down.

One end of each synchronous cover wheel 62 passes through the rotating hole of the cover vertical plate 61 and is connected to the driven gear 643 on the outer side of the cover vertical plate 61.The capping drive motor 641 drives the drive gear 642 to rotate. Under the rotation of the chain 644, the drive gear 642 drives several driven gears 643 to rotate. During the rotation of the driven gears 643, several synchronous capping wheels 62 will rotate. When the tank body 9 and the can cover 8 on it are transported together in the discharge conveying section 712 of the tank body conveying structure 7, several synchronous capping wheels on the can cover 8 will also rotate. This allows several synchronous capping wheels 62 to press down the tank body 9 covered with the can cover 8 on the tank body conveying structure 7, so that several synchronous capping wheels 62 can press the can cover 8 completely down to the bottom of the tank body 9, realizing the synchronous operation of capping and discharge conveying.

[0040] The working process of this automatic synchronous capping machine includes the following steps:

[0041] First, the feeding conveyor section 711 of the tank conveyor belt 71 transports the tank 9 of the tank cover 8 to the positioning turntable 41, where the tank 9 is accommodated by the second limiting groove 415 of the lower turntable 413 of the positioning turntable 41.

[0042] Secondly, the can lid 8 is transported to the area below the can lid suction mechanism 24 via the can lid conveyor belt 31 of the can lid conveying structure 3. When the rotary motor 43 is started, it drives the turntable shaft 42, the lower turntable 413, the can body 9 on the lower turntable 413, and the upper turntable 411 to rotate together, so as to transport the can body 9 of the can lid 8 to be pressed to the area below the can lid suction and delivery structure 2. The can lid suction and delivery structure 2 controls the suction cup fixing plate 241, the first can lid suction plate 242, and the second can lid suction plate 243 to descend to the area above the can lid conveying structure 3 via the can lid lifting cylinder 23. The first can lid suction plate 242 is in the true position. Under the action of the empty pipe and vacuum pump, the first suction plate 242 first sucks the can lid 8 conveyed on the can lid conveying structure 3, and then the suction plate rotating cylinder 22 drives the suction cup fixing plate 241 and the first suction plate 242 and the second suction plate 243 with the can lid 8 to rotate 180°. At this time, the first suction plate 242 with the can lid 8 is located above the positioning turntable 41. The suction plate lifting cylinder 23 drives the suction cup fixing plate 241 and the first suction plate 242 and the second suction plate 243 to descend so that the can lid 8 on the first suction plate 242 is placed on the can body 9 of the positioning turntable 41.

[0043] Then, the rotary motor 43 drives the turntable shaft 42, the lower turntable 413, the can 9 on the lower turntable 413, and the upper turntable 411 to rotate, transporting the can 9 with the can lid 8 to below the first can lid pressing station 51. The first can lid pressing station 51 drives the first pressing head 513 to move up and down through the first pressing lifting cylinder 512, so that the first pressing head 513 presses down the can lid 8 placed on the can 9 for the first time, and then continues to the next can lid. During the first pressing operation of the can lid 8 of the can body 9, the rotary motor 43 continues to drive the turntable shaft 42, the lower turntable 413, the can body 9 on the lower turntable 413, and the upper turntable 411 to continue rotating, conveying the can lid 8 and the can body 9 that have undergone the first pressing operation to the area below the second can lid pressing station 52; the second can lid pressing station 52 drives the second pressing head 523 to move up and down through the second pressing lifting cylinder 522, so that the second pressing head 523... The can lid 8 placed on the can body 9 is pressed down a second time, and the second pressing operation of the can lid 8 of the next can body 9 continues. At the same time, the rotary motor 43 continues to drive the turntable shaft 42, the lower turntable 413, the can body 9 on the lower turntable 413, and the upper turntable 411 to continue rotating, conveying the can lid 8 and can body 9 that have undergone the second pressing to below the third can lid pressing station 53; the third can lid pressing station 53 drives the third pressing lifting cylinder 532 to the third The pressing head 533 moves up and down, causing the third pressing head 533 to press down the lid 8 placed on the tank body 9 for the third time, and continues the third pressing operation of the lid 8 of the next tank body 9. At the same time, the rotary motor 43 continues to drive the turntable shaft 42, the lower turntable 413, the tank body 9 on the lower turntable 413, and the upper turntable 411 to rotate, conveying the lid 8 and the tank body 9 that have been pressed down three times to the discharge conveying section 712 of the tank conveyor belt 71.

[0044] Finally, the cap lifting mechanism 63 drives the cap vertical plate 61 and several synchronous capping wheels 62 on the cap vertical plate 61, and the cap driving mechanism 64 to move up and down as a whole, so that the several synchronous capping wheels 62 move downward as a whole, completely pressing the can cover 8 on the can conveying structure 7 down to the bottom of the can 9. The cap driving motor 641 drives the drive gear 642 to rotate. Under the rotation of the chain 644, the drive gear 642 will drive several driven gears 643 to rotate. During the rotation of the several driven gears 643, the several synchronous capping wheels 62 will rotate. The several synchronous capping wheels above the can cover 8 will also rotate, so that the several synchronous capping wheels 62 can press down the can 9 covered with the can cover 8 conveyed on the discharge conveying section 712, so that the can cover 8 can be completely pressed down to the bottom of the can 9.

The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
