Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt transportation, in particular to a conveyor belt transition device. Background Art

[0002] During the sorting process of cigarette strips, the cigarette strips are conveyed from the dispensing machine to the packaging machine according to the direction of the conveyor belt. When the conveying distance is long, it is sometimes necessary to use multiple conveyor belts for relay transmission, because there must be gaps at the connection between the two conveyor belts. It is precisely because of these gaps that the cigarette strips are often stuck in the gap. In order to avoid jamming, a conveying transition device is usually set between the two conveyor belts. After the cigarette strips pass through the conveying transition device from the front end of the rear conveyor belt, they can smoothly reach the front conveyor belt. The existing conveying transition device usually sets a transition plate between the front and rear conveyor belts, but the width of the existing transition plate is consistent with the width of the conveyor belt. Due to the layout of the site, when a longer conveying transition device needs to be installed, since the transition plate has no driving force, it can only rely on the driving force of the rear cigarette strip to push it forward. In the process of relying on the rear cigarette strip to push it forward, the cigarettes are prone to skew, disorder or even fall, thereby causing production waste, affecting the normal transportation of the cigarette strips, and further affecting production efficiency.
