Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tobacco shred production, and particularly relates to a thin-sheet cigarette pack pre-loosening device. Background Art
[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.
[0003] The paper-made thin cigarette packs currently used in tobacco silk production lines cannot be directly cut into pieces after opening the box due to their high product density; therefore, the current method of processing paper-made thin cigarette packs in most tobacco silk production lines is to put the entire pack of thin cigarette packs after opening the box into a rehumidification drum, and break up the entire pack of thin cigarette packs through the rolling of the rehumidification drum and the nails inside it.
[0004] However, the inventors have found that directly sending the thin cigarette packs into the rehumidification drum for loosening has a slow loosening speed, and due to the loosening order of the thin cigarette packs, the thin slices at the core of the thin cigarette packs are usually difficult to rehumidify, resulting in uneven humidity of the thin slices at the outlet of the rehumidification drum.
[0005] A few tobacco silk production lines use a special roller loosening device to loosen the paper-thin cigarette bales individually before they enter the rehumidification drum. However, the loosening speed of this device is slow and the thin slices at the core of the cigarette bales are compacted tightly and easily get stuck in the loosening device, causing shutdown.
[0006] Some tobacco silk production lines use an inserting and separating device to separate the paper-made thin cigarette packs before they enter the rehumidification drum. However, the inserting and separating device can only separate certain points and cannot cover any complete side of the cigarette pack, and its loosening capacity is limited. Utility Model Content

[0034] Embodiment 1
[0035] As Figures 1 to 3 shown, the present utility model provides a thin cigarette packet pre-loosening device, including: a material conveying channel 1 and an extrusion cylinder 2;
[0036] The number of the extrusion cylinders 2 is two, and the two extrusion cylinders 2 are respectively rotatably arranged on both sides of the material conveying channel 1, and the rotation directions of the two extrusion cylinders 2 are opposite.
[0037] In the present utility model, the cigarette packet 7 moves forward through the material conveying channel 1. When passing through a door-shaped channel composed of two rotating extrusion cylinders 2, the two extrusion cylinders extrude the passing thin cigarette packet, causing the thin cigarette packet to move in the vertical direction and generate gaps, thereby achieving the purpose of loosening.
[0038] Furthermore, a plurality of rake nails are provided on the outer surface of the extrusion cylinder 2, and the rake nails are arranged in an axial array along the extrusion cylinder 2.
[0039] In this embodiment, studs are arranged on the outer surface of the extrusion cylinder to further enhance the looseness of the cigarette packets. After extrusion, the cigarette packets become loose in the vertical direction, and the loosening direction is perpendicular to the advancing direction of the cigarette packets.

The material conveying channel 1 is fixed on the main body frame 4, and the extrusion cylinder 2 is rotatably arranged on the main body frame 4. The first driving mechanism is used to drive the extrusion cylinder 2 to rotate around its central axis.
[0042] The main body frame 4 is a vertically arranged frame structure.

[0043] Each extrusion roller is connected to the belt pulley 3 and the driving motor 6. The driving motor 6 can be fixed on the frame 4 or separately fixed on the ground, and the installation position of the driving motor 6 can be adjusted according to actual needs. After the driving motor 6 is started, it drives the driving belt pulley to rotate, and the driving belt pulley drives the driven belt pulley to rotate through the synchronous belt, thereby realizing the rotation of the extrusion roller. The extrusion roller and the driving motor can also be connected by a chain sprocket or a gear, which will not be elaborated here.
[0044] Furthermore, second driving components for driving the extrusion cylinder 2 to move along the length direction of the main body frame 4 are arranged on the frame beams on both sides of the main body frame to realize the adjustment of the distance between the two extrusion cylinders 2.
[0045] The second driving component includes a hydraulic cylinder 5 and a C-shaped push plate. The hydraulic cylinder 5 is arranged on the main body frame 4, and its output shaft is connected to the side end of the C-shaped push plate. The upper end and the lower end of the C-shaped push plate are respectively slidably arranged in the sliding tracks on the upper frame beam and the lower frame beam of the main body frame 4.
