This utility model provides a sample-keeping anti-counterfeiting incense packaging tube, belonging to the field of incense packaging technology. It includes a top cover, a connecting tube, and an incense tube. The connecting tube has a reserved channel with a limiting component. The limiting component contains multiple radially distributed tooth-shaped elastic limiting pieces. In its natural state, the tips of the elastic limiting pieces form a conical protrusion, enclosing a closed limiting hole. This utility model, through the deformation and reset characteristics of the elastic limiting pieces, strictly restricts the incense to only moving from the incense tube towards the top cover for sample incense sampling and inspection. Once all incense is removed, it cannot be reversed, preventing incense inconsistent with the incense already in the tube from being mixed back into the tube. This avoids confusion between different batches and qualities of incense, ensuring the consistency between the incense quality in the packaging tube and the seller's quality commitment. This helps quality-conscious and reputable companies protect their products from counterfeiting or malicious complaints and claims.

A lower conveying roller and an upper conveying roller, symmetrically arranged for conveying the substrate, are rotatably connected within the first mounting frame, forming a conveying channel between them. When a thick substrate passes through, the upper conveying roller is pushed upwards along the first mounting frame, and the diverting frame is simultaneously raised via a connecting plate and connecting strip, preventing the dispensing tube from scratching the substrate and causing localized glue accumulation. Simultaneously, the connecting strip drives the transmission rack to mesh with the driven gear, which in turn drives the threaded rod to rotate via a synchronous pulley and synchronous belt. This causes the circular structure formed by the arc-shaped block to shrink, slowing down the rotation speed of the mixing frame, thickening the adhesive, and fully filling the pores of the thick substrate to improve adhesion. When a thin substrate passes through, the upper conveying roller falls back, causing the diverting frame to descend, preventing glue splashing and ensuring a uniform adhesive layer.
