Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging detection devices, and more specifically to a cigarette package uniform acceleration sub-packaging device for invisible code spraying detection of special-shaped cigarette packages. Background Art

[0002] During the cigarette production process, special-shaped cigarette packs are invisible-inked through a coding mechanism. A cigarette pack conveyor channel is located at the inlet of the coding mechanism, through which cigarette packs are transported to the coding mechanism for coding. The cigarette pack conveyor channel is formed by the gap between two conveyor belts positioned opposite each other. The friction between the two conveyor belts and the cigarette packs drives the cigarette packs in the channel from back to front.

[0003] At present, the channel width between the two conveyor belts of the cigarette pack conveying channel is constant. When the cigarette packs enter the conveying channel, it is easy for the two cigarette packs in front and behind to be connected end to end. The photoelectric sensor identifies the two cigarette packs as one cigarette pack. When the subsequent coding mechanism performs coding, it only codes on one cigarette pack, and the other cigarette pack that is stuck together will miss coding, affecting the normal and accurate coding work. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a cigarette pack uniformly accelerated packing device for detecting special-shaped cigarette packs with invisible inkjet coding.

[0005] The utility model is realized through the following technical solutions:

The cigarette package conveying channel includes two conveyor belts arranged on a base and arranged opposite to each other on the left and right. The gap between the two conveyor belts constitutes a conveying channel extending front to back. The two ends of each conveyor belt are connected for transmission by a driving pulley and a driven pulley. The ends of the two conveyor belts with the driven pulleys are the inlet ends and the ends with the driving pulleys are the outlet ends. The side of the conveyor belt close to the conveying channel is the inner side. The middle section of the inner side of each conveyor belt is tensioned by multiple tensioning pulleys. The conveying channel between the two conveyor belts is provided with an entrance transition section near the entrance end. The entrance transition section is trumpet-shaped with the entrance end expanding outward.

[0007] As a preferred solution of the above-mentioned device, the driven pulleys at the inlet end of each conveyor belt are detachably mounted on the base, the driven pulleys are mounted on the base through a mounting bracket, the mounting bracket is fixedly mounted on the base, the mounting bracket is provided with a mounting plate extending horizontally to above the driven pulley, the mounting plate is provided with a waist-shaped hole extending in the left and right directions, the driven pulley is rotatably mounted on the driven pulley shaft, the driven pulley shaft is provided with a threaded hole, the bolt is passed through the waist-shaped hole of the mounting plate and then tightened in the threaded hole of the driven pulley shaft, thereby realizing the locking installation of the driven pulley shaft and the mounting bracket.

[0008] As a preferred solution of the above device, the upper end of the driven pulley shaft is provided with an embedded end that can slide with the waist-shaped hole of the mounting plate, and the front and rear sides of the embedded end of the driven pulley shaft slide with the front and rear sides of the waist-shaped hole of the mounting plate respectively.

[0009] As a preferred solution for the above-mentioned device, the axial center distances of the left and right sets of tensioning pulleys corresponding to the two conveyor belts are equal as the conveying axial center distance, and the axial center distance of the driven pulleys of the two conveyor belts is used as the entrance axial center distance, which is greater than the conveying axial center distance.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] The utility model provides a device for uniformly accelerating the packaging of cigarette packages for invisible coding detection of special-shaped cigarette packages. Since the entrance transition section of the conveying channel is in the shape of a trumpet with the entrance end expanding outward, that is, the conveying channel gradually narrows along the conveying direction, the cigarette package's travel speed gradually accelerates and is uniformly accelerated during the process of the cigarette package passing through the entrance transition section, so that the front and rear cigarette packages can be smoothly separated, thereby realizing smooth packaging operation of the incoming cigarette packages, effectively avoiding the occurrence of coding errors or coding omissions caused by connected cigarette packages, and ensuring smooth and accurate coding operation.
