Description

Technical Field

[0001] The utility model relates to the field of cigarette production, in particular to a sorting line for cigarette popping beads. Background Art

[0002] With the development of the tobacco industry, controlling the quality of cigarette beads under large-scale production is a daunting task and a guiding goal for scientific and technological innovation.

[0003] In the production process of tobacco popping beads, it is impossible to 100% guarantee that the popping beads meet the process requirements. In order to control the quality of the finished tobacco popping beads during the production process, in addition to the improvement of the pelletizing and drying process technology, the finished product inspection at the back end of the popping beads is the key to controlling the final quality of the popping beads.

[0004] At present, most of the detection methods available on the market are visual inspection technologies, which use visual images to detect defects in each popping bead, and then use compressed air at the back end to remove unqualified products such as tailings, connected beads, and particle size; the slid screen with manual loading and unloading can complete the screening of tailings and connected beads; the rotary barrel screen with manual loading and unloading can complete the sorting of popping beads of different particle sizes, etc. However, the existing detection methods and instruments cannot guarantee stable detection quality, as well as the sorting of different types of unqualified products. Personnel loading and unloading are also required, which has low efficiency and high labor costs.

[0005] The existing inspection equipment is a single-body design, that is, all links in the inspection process of tobacco popping beads are still operated separately. For example, according to the sorting technology currently available on the market, the roundness screening of the popping beads requires one manual operation. The diameter screening requires two manual operations. The screening of internal defects of the popping beads requires one manual operation, and the inspection process of this link requires at least 4 manual costs. In addition, due to the reliability of the roundness and diameter screening effects at the front end, the back-end visual selection part is prone to downtime failures and increases the risk of erroneous rejection, which will result in the need for secondary rework and inspection.

[0041] like Figure 3 As shown, the loading parts include a transfer bin 16, a conveyor belt 17, a first motor, a loading wheel 18 and a loading guard plate 19. The feed port of the transfer bin 16 is connected to the discharge port of the storage bin 26. The rotating shaft of the first motor is fixedly connected to the rotation center of the loading wheel 18. At least one loading annular groove 20 is provided on the loading wheel 18.
