Description

Technical Field

[0001] The utility model relates to the technical field of strip-shaped thin sheet material processing and forming equipment, in particular to an adhesive splicing device and continuous supply equipment for strip-shaped materials. Background Art

[0002] In the production process of the tobacco production industry, there are many cases where the raw materials are in the shape of strip materials; for example, cigarette paper and cigarette box lining paper in traditional tobacco; for example, the thin tobacco leaf raw materials of new low-temperature non-burning tobacco and PLA materials in the cooling section. One problem that strip materials must face is that after the material is consumed, the old strip material must be removed and a new strip material must be installed. At present, during the replacement of strip materials, the equipment must be shut down, which will inevitably affect production efficiency. Due to the limitations of machines and manpower, the raw material paper rolls cannot be made particularly large. In addition, the production speed has been gradually increased due to the upgrading of tobacco machinery. The downtime consumed by the frequent replacement of strip materials seriously restricts the improvement of production efficiency.

[0003] For tobacco production enterprises, there is an urgent need for a splicing device that can automatically connect the strip material that is about to be consumed with the new strip material end to end, so as to save the downtime required for changing materials and ensure production efficiency. The existing splicing device is a cigarette paper glue overlapping device on the KDF2 filter rod forming machine, which achieves the purpose of splicing cigarette paper through ingenious mechanical structure and electrical control. However, this splicing method also has its limitations. The complex mechanical structure and high-speed swinging blades limit it to only be used for strip materials with a narrower width. The lining paper of cigarette boxes and the thin tobacco materials of new tobacco are all more than 100mm wide. Faced with raw materials of this width, the overlapping device on the KDF2 filter rod forming machine is obviously not competent. Therefore, another form of overlapping structure is needed to cope with the wider width and adapt to a wider range of use environments. Utility Model Content
