Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a pack-replacing machine, in particular to a novel cigarette pack-replacing machine. Background Art

[0002] The tobacco product packaging industry has increasingly higher requirements for packaging speed, efficiency and quality. However, during the refilling process of the traditional hard box packaging machine at the transparent paper packaging machine, due to mechanical structure limitations, the original cigarette tower device cannot store a large number of cigarette packs, and the operator needs to add them manually continuously. If other matters need to be operated while the equipment is running, they cannot be taken care of, resulting in low refilling efficiency. In addition, since the bottom cigarette packs cannot be automatically emptied, they are often missed during closing or brand change production, which will cause problems such as product brand confusion.

[0003] For example, a cigarette pack automatic refilling device disclosed in a Chinese patent document (application number: 201120388581.2) includes a cigarette bin, a support, a push cylinder, a smoke blocking cylinder, a detection sensor and a control system; the support is fixedly arranged on the cigarette pack conveying channel, the cigarette bin is arranged on the support, a push cylinder is arranged between the cigarette bin and the cigarette pack conveying channel, a smoke blocking cylinder is arranged on one side of the support, and detection sensors are arranged on the cigarette pack conveying channels at both ends of the support. When the detection sensor detects that there is no cigarette pack passing through the cigarette pack conveying channel, the control system controls the smoke blocking cylinder to block the cigarette pack in the upstream machine of the cigarette pack conveying channel, and at the same time, the push cylinder pushes out the lowest cigarette pack stacked in the cigarette bin, enters the cigarette pack channel, and conveys it to the downstream machine; when the detection sensor detects that there is a cigarette pack in the cigarette pack conveying channel, the push cylinder stops pushing the cigarette pack, and at the same time, the smoke blocking cylinder retreats. However, the automatic cigarette pack refilling device has low refilling efficiency and is not reliable and stable enough. Summary of the invention
