Description

Technical Field

[0001] The utility model relates to a tobacco beetle monitoring device accessory for a cigar factory, belonging to the technical field of cigar quality control. Background Art

[0002] Tobacco beetles have always been one of the quality risk sources in the tobacco manufacturing process. In the production of tobacco in the workshop, tobacco beetles often bore into and eat tobacco leaves and cigars. Tobacco beetles have a strong reproductive capacity, which has an adverse impact on the normal production of tobacco. In order to timely grasp the insect situation in the production area, the tobacco factory will use tobacco beetle traps to monitor the insect situation on site. The traps are hung in various places in the workshop. Once sanitary maintenance is carried out, dust and tobacco residue will adhere to the rubber surface of some traps, affecting the effect of insect monitoring. It will also cause misdetection and misidentification of intelligent insect equipment. When the area of ​​the trap rubber surface is contaminated to a certain extent, a new trap must be replaced, which invisibly increases the cost of insect monitoring. This has resulted in a certain waste of resources and inconvenience in work.

[0003] Based on the above reasons, there is an urgent need for a dust-proof device for beetle traps to protect the traps from pollution and reduce the replacement frequency of the traps while ensuring the accuracy of insect detection.

[0004] The existing method of setting up insect traps on the production line is hanging type. Screws are screwed into the place where insect monitoring is required, and then the insect trap is hung on the screws. However, it is not suitable for all insect monitoring areas. For example, tobacco packaging equipment cannot be damaged by screws being screwed in.

[0005] After the production of some tobacco production lines is completed, the equipment and facilities need to be ash-blown for maintenance. A large amount of dust will adhere to the adhesive surface of the insect trap, greatly reducing the insect-binding effect of the trap and making the trap ineffective. To avoid the failure of the insect trap, the staff needs to recycle the trap before the ash-blowing maintenance, and re-hang it after the ash-blowing maintenance is completed and the dust has fallen for a period of time. The tobacco production line has a long process and a large space area. There are more than 50 insect traps in a workshop, and the labor intensity of dismantling and hanging is high.

[0006] Alternatively, the existing tobacco beetle detection and dust prevention device adopts through holes, fence bars, shutters, semi-elliptical covers, etc. for dust prevention. However, this technical solution also has certain inconveniences. During use, although it can achieve the purpose of dust prevention, when it is used specifically, it will affect the beetles from entering the box, thereby reducing the trapping efficiency. On the other hand, it is not conducive to the odor dissipation of the attractant core during use, thereby further reducing the trapping efficiency. Therefore, it needs to be improved.
