Description

Technical Field

[0001] The present invention relates to the technical field related to carton processing, and in particular to a carton opening and packing integrated packaging machine applicable to cartons of different sizes. Background Art

[0002] Automatic unpacking and packing machine is a commonly used automatic packaging equipment for product packaging. The automatic unpacking and packing machine can realize automatic unpacking, automatic packing and automatic sealing operations. It has high packaging efficiency and automatic operation, which can reduce manual operation.

[0003] There are many types of existing unpacking and packing integrated packaging machines, but there are still certain deficiencies in their use. When facing cartons of different sizes, the operation is relatively cumbersome and cannot be well adapted to the operation and use of cartons of different sizes.

[0004] In order to overcome the above-mentioned defects, reference can be made to the fully automatic carton opener disclosed in the prior art (Chinese patent with application number CN201811649033.3 and publication date 2021-07-27). The fully automatic carton opener utilizes a mounting plate that is driven up and down by a lifting cylinder, and the first carton opener plate of the first carton opener assembly and the second carton opener plate of the second carton opener assembly can both move inward and outward. The entire machine is easy to adjust and can perform unpacking operations on packaging boxes of different sizes. It has a wide range of applications, and one machine can meet the use requirements.

[0005] In addition, reference may be made to an automatic carton opening mechanism disclosed in the prior art (Chinese patent application number CN201610320595.8, publication date 2018-04-13), in which the suction cups located on the diagonal sides of the two parallel S-shaped links suck the two sides of the carton board, and the S-shaped link is driven to move by the large-angle deformation of the four-bar linkage from +135 degrees to -135 degrees. The S-shaped link plays a role in changing the direction, converting the inclination angle of the inclined side of the four-bar linkage into a parallel angle for facilitating the absorption of the carton board. When the S-shaped link completes the angle change from +135 degrees to -135 degrees with the four-bar linkage, the suction cup mounting rods located on the diagonal sides of the two parallel S-shaped links move to a vertical angle, so that it can be conveniently adapted to cartons of different sizes for use.

[0006] At the same time, you can also refer to the prior art (Chinese patent with application number CN202110680417.7 and publication date 2023-02-14), which discloses a vertical high-speed carton opener. The carton opener utilizes a box blank forming component including a width adjustment component and two box blank conveying components arranged side by side. The box blank width adjustment component is respectively connected to the two box blank conveying components. The box blank width adjustment component is used to adjust the distance between the two box blank conveying components to adapt to box blanks of different sizes.

[0007] Although the above method can solve the problem of unpacking cartons of different sizes, there are still certain shortcomings in the working process. When sealing the upper and lower ends of the carton, it is usually necessary to disconnect the carton and then seal the top surface. This operation is cumbersome and inefficient.

[0029] When the carton is transported to the top of the placement plate 18, the tape body 191 drives the tape to adhere to the leftmost end of the carton, and by continuing to push the carton, the tape body 191 will also be driven to rotate, so that the tape can seal the bottom of the carton, and then the objects to be placed are placed inside the carton by a robot or manually. At this time, the height of the telescopic matching plate 27 is adjusted to avoid interference between the cartons during rotation, and then the air is continued to be supplied, so that the second air supply pipe 28 transports the inside of the sealing cylinder 29, and then the second spiral sleeve 30 slidably arranged inside the sealing cylinder 29 will move. The spirally connected spiral rod 31 drives the rotating rod 32 to rotate inside the telescopic matching plate 27, thereby driving the carton and the objects inside the carton to rotate. Since the tape is always present, the tape can interfere with the top of the carton, and through the rotation of the carton, the tape can fully seal the carton. When the second spiral sleeve 30 moves to the maximum position, the carton will no longer rotate, so that the gas can be continuously transported to the groove opened by the placement plate 18, and the cutting blade 35 can be extended in the groove through the reset spring 34, and the tape is cut through the top position of the cutting blade 35 to facilitate the next packaging of the carton.
