Background

The carton has the advantages of easily available materials, light weight, easy printing, low cost and the like, thereby being widely applied to packaging products. In the conventional technology, the carton is sealed by manual operation, namely, the carton is sealed by a transparent adhesive tape manually, so that the labor intensity is high, and the sealing pressure is not uniform enough. In the prior art, a document (publication number: CN 106516282B) discloses a transparent adhesive tape type linear sealing machine for carton packaging, which can realize semi-automatic sealing adhesive tape, but has the following two disadvantages: firstly, the adhesive tape needs to be manually dragged again for each sealing, namely, manual participation is still needed; secondly, the height of the roller is fixed in the rolling process, namely, the seal of the adhesive tape belongs to a rigid seal, and the partial adhesive tape of the carton is easy to wrinkle.
