Background technique

The spiral compression molding machine has the characteristics of fast and uninterrupted compression molding of materials, and can compress a large amount of loose materials into a compact and regular shape, which is convenient for storage and transportation. In the field of agricultural production, materials such as crop stalks and silage feed have a large amount and small specific gravity, and can be compressed and bundled into compact cylindrical entities, and the screw compression molding machine can complete this work. However, for such agricultural materials, after compression molding, if the materials such as ropes and tapes are not fixed in time, the materials will disperse after leaving the molding machine. Therefore, it is necessary to use adhesive tape and its installation structure.

During the working process of the screw compressor, it is necessary to wrap the tape on the outside of the molding material to effectively prevent the material from spreading. Therefore, it is necessary to arrange a tape conveying mechanism in different directions of the cylindrical entity, and to wrap the tape on the surface of the cylindrical entity. Simultaneously apply a compressive force, so that the intersecting tapes stick together to form a network. In addition, during the working process of the tape conveying mechanism, a new tape needs to be replaced after a roll of tape is used up. In order to improve work efficiency, it is necessary to design a mechanism that can easily replace the tape.
