Description

Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, and in particular to a device for improving cigarette pack misalignment in the conveying channel of a packaging machine. Background Technology

[0002] Before the small cigarette packs enter the C600 transparent paper packaging machine, they are conveyed to the machine's inlet via a conveyor channel. During this process, misalignment frequently occurs when the cigarette packs reach the turning position. This is primarily because the conveyor channel is formed by the gap between two opposing conveyor belts. The cigarette packs are conveyed by the friction between the belts and the packs, clamped by the two belts. When the conveyor channel is too long, the middle section of the belts may collapse, failing to effectively clamp the packs and causing them to shift. This misalignment prevents the packs from turning smoothly at the turning position, leading to machine downtime. Sometimes, it can even deform the packs, affecting packaging quality. Utility Model Content

[0014] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0015] See Figures 1 to 2This embodiment discloses a device for improving cigarette pack misalignment in the conveyor channel of a packaging machine. The conveyor channel is formed by the gap between two conveyor belts 1 arranged opposite each other. The two conveyor belts 1 clamp the left and right sides of the cigarette packs to convey the small cigarette packs 2. The two conveyor belts 1 are installed on the conveyor frame. The side of the conveyor belt 1 facing the conveyor channel is the outer side, and the side away from the conveyor channel is the inner side. Each conveyor belt 1 has at least one set of tensioning components 3 on its inner side. In this embodiment, three sets of tensioning components 3 are spaced apart on the inner side of the conveyor belt 1. Each set of tensioning components 3 includes a chassis 4 and a tensioning wheel. The chassis 4 has a tensioning wheel mounting shaft 5 and a main mounting shaft 6 at its upper and lower ends, respectively. The tensioning wheel mounting shaft 5 and the main mounting shaft 6 are eccentrically arranged, and their centerlines both extend vertically. The main mounting shaft 6 is detachably installed on the conveyor frame. The main mounting shaft 6 is a stud. After the main mounting shaft 6 passes through the mounting hole on the conveyor frame, the mounting nut is tightened to achieve a locking installation between the main mounting shaft 6 and the conveyor frame.

[0016] The tensioning wheel is rotatably mounted on the tensioning wheel mounting shaft 5, and tensions the conveyor belt 1 through its circumferential surface. The upper end of the tensioning wheel mounting shaft 5 is an externally threaded end. The tensioning wheel includes two bearings 7, which are spaced apart on the tensioning wheel mounting shaft 5. The two bearings 7 are separated from each other, and the lower bearing 7 is separated from the chassis 4 by spacers 8. Locking nuts 9 are screwed onto the externally threaded end of the tensioning wheel mounting shaft 5 and abut against the upper bearing 7, thus locking the two bearings 7 to the tensioning wheel mounting shaft 5. By selecting spacers 8 of different specifications, the vertical position of the two bearings 7 can be adjusted to adjust the tension position of the conveyor belt 1, ensuring the tensioning effect of the conveyor belt 1.

[0017] The packaging machine conveyor channel cigarette pack misalignment improvement device provided in this embodiment uses tensioning components 3 installed on the inner sides of the two conveyor belts 1 on both sides of the conveyor channel. Each tensioning component 3 relies on the circumferential surfaces of two bearings 7 to press against the inner side of the conveyor belt 1, achieving effective tensioning of the conveyor belt 1. In each tensioning component 3, by loosening the mounting nut and rotating the main mounting shaft 6, the distance between the axis of the tensioning wheel mounting shaft 5 and the conveyor belt 1 can be adjusted by relying on the eccentric setting between the tensioning wheel mounting shaft 5 and the main mounting shaft 6. After adjustment, the mounting nut is tightened, allowing flexible adjustment of different tension forces at different positions in the conveying direction of the conveyor belt 1. This ensures that the clamping force of the conveyor belt 1 on the small cigarette packs 2 is maintained throughout the entire conveyor channel, ensuring the centered conveying of the small cigarette packs 2 and preventing misalignment when reaching the cigarette pack turning position, thus ensuring product quality and improving equipment production efficiency.

[0018] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
