[0002] Paper is a sheet material made of plant fibers as the main raw material through processes such as pulping, papermaking, drying, etc. During the processing of paper, the raw materials need to be transported to the papermaking equipment through the feeding mechanism for multi-stage processing, and finally the paper is made.

The technical scheme is that a bottom frame and a spiral conveyor cylinder are included. The bottom frame further includes four stand columns. The four stand columns are fixedly connected through a plurality of first connecting beams and second connecting beams. Two second connecting beams are further fixedly connected with a connecting plate. The connecting plate movably installs a top block. An adjusting screw is movably installed in the connecting plate. An inlet hopper is arranged at the upper position of the bottom frame. The inlet hopper is fixedly installed on the bottom frame through a plurality of supporting columns. Two fixed rods are fixedly installed on the outer side of the spiral conveyor cylinder.

[0004] In the existing technology, paper is generally fed through an auger feeding mechanism during feeding. During the feeding process, the spiral conveying shaft on the auger will rub against the raw materials when rotating, causing some raw materials to generate debris due to friction. The debris will be transported together with the raw materials into the papermaking equipment, thereby causing obstacles to the processing of raw materials by the papermaking equipment, and the use effect is poor. Moreover, the raw materials cannot be preheated during transportation, causing the raw materials to be transported to the papermaking equipment in a low-temperature state, which hinders the high-temperature environment in the papermaking equipment, thereby affecting the processing efficiency of the raw materials by the papermaking equipment, and the use effect is poor.
