DETAILED DESCRIPTION

[0017] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0018] The utility model provides a labeling machine suitable for drum-shaped packaging, comprising a conveyor belt 1 for transmitting drum-shaped packaging, a first roller device 2 for arranging labeling paper, a second roller device 2.1 for arranging labeling paper base paper, and a partition plate 3 for separating labeling paper stickers and base paper, wherein the first roller device 2, the second roller device 2.1 and the partition plate 3 are all arranged on the same side of the conveyor belt 1, the labeling paper is supplied by the first roller device 2, the labeling paper stickers and the base paper are separated at the partition plate 3 through a plurality of rotating shafts, and the base paper is collected by the second roller device 2.1 through a plurality of rotating shafts, and the utility model further comprises an active roller 4, the active roller 4 is located beside the partition plate 3, and forms an avoidance with the partition plate 3, and the labeling paper sticker part is located in front of the active roller 4; and a passive roller 5, the passive roller 5 is located on the other side of the active roller 4 relative to the conveyor belt 1, the passive roller 5 is arranged on a cylinder 5.1, and the cylinder 5.1 can drive the passive roller 5 to move toward the active roller 4 side.

[0019] The active roller 4 of the utility model is driven by a driving device 4.1 and is always in a rotating state during operation. The active roller 4 is mounted on a first frame 4.3 through a first bearing 4.2. A flexible stopper 4.4 is provided on the top of the first frame 4.3. One end of the flexible stopper 4.4 is connected to the first frame 4.3, and the other end is bent and located on the side of the partition plate 3 close to the conveyor belt 1, so as to limit the displacement generated when the labeling paper is separated.

[0020] The passive roller 5 is mounted on the second frame 5.3 through the second bearing 5.2. The second frame 5.2 is connected to the first cylinder 5.1. The second frame 5.2 is also provided with an infrared probe 5.4 for identifying the barrel-shaped packaging.

[0021] The second frame 5.3 is provided with a baffle 5.5 at the front side of the conveying direction of the conveyor belt 1. The baffle 5.5 is connected to the second cylinder 5.6. The second cylinder 5.6 drives the baffle 5.5 to move toward the active roller 4 side.

[0022] When the cylindrical package is driven by the conveyor belt 1 and arrives in front of the passive roller 5, the infrared probe 5.4 in the passive roller 5 detects the cylindrical package, and the first cylinder 5.1 pushes the second frame 5.3 and the passive roller 5 to move toward the active roller 4 until the active roller 4 and the passive roller 5 clamp the cylindrical package. At the same time, the second cylinder 5.6 pushes out the baffle 5.5, and the other packages behind the currently clamped cylindrical package are blocked on the assembly line.

[0023] The driving device 4.1 drives the active roller 4 to roll. The active roller 4 generates friction due to the clamping with the drum-shaped packaging, which drives the drum-shaped packaging to roll. The passive roller 5 on the other side is set on the second bearing 5.2, which can ensure the free rolling of the drum-shaped packaging. While clamping and rolling, the first roller device 2 drives the labeling paper to feed. After passing through several rotating shafts, the labeling paper passes through the partition plate 3. Under the action of the partition plate 3, the sticker and the base paper of the labeling paper are separated. The sticker is separated and fed into the gap between the active roller 4 and the drum-shaped packaging, and is applied to the surface of the drum-shaped packaging under the clamping and rolling of the active roller 4 and the passive roller 5; the base paper is always close to the several rotating shafts and rolled up by the second roller device 2.1 because the other end is rotated and stored on the second roller device 2.1, and because the flexible limiter 4.4 is set, the base paper does not shake or move when it is separated by the partition plate 3 and enters the rotating shaft. When the infrared probe 5.4 of the passive roller 5 detects that the barrel-shaped package has rotated a circle, the first cylinder 5 is controlled to retreat, release the clamping, and release the barrel-shaped package to move forward under the drive of the conveyor belt 1, and the second cylinder 5.6 is controlled to retreat synchronously, and the baffle 5.5 retreats accordingly, so that the packages piled up at the rear can move forward under the drive of the conveyor belt 1.

[0024] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
