The application discloses a straw cutting and anti-winding integrated device for biomass fuel, and belongs to the field of biomass fuel processing equipment, which solves the problems of easy winding, low cutting precision and poor running stability of the existing straw cutting mechanism. The device comprises a mounting frame, a driving assembly, a rotary cutting assembly, a floating cutting assembly and a floating baffle assembly. The driving assembly drives an output driving shaft to drive the rotary cutting assembly to operate. The output driving shaft drives the floating cutting assembly through a gear reverser. The two are vertically arranged. The floating baffle assembly is hinged to the lower part of the mounting frame and below the rotary cutting assembly. The application adopts a double-stage cutting structure, cooperates with the anti-winding and buffering design, realizes accurate straw cutting and whole-process anti-winding, and has uniform cutting length. The device is stable in operation, low in maintenance cost, high in operation efficiency, and suitable for the large-scale processing of biomass fuel straw raw materials.

The utility model provides a kind of double-arrow-shaped metamaterial corrugated strip multi-step semi-automated forming platform, the utility model places initial rectangular corrugated strip in forming area first, through the folding mechanism and pressure block propulsion mechanism with spatial phase difference distribution characteristics, combined with multistage progressive extrusion path planning strategy, realize double-arrow-shaped metamaterial corrugated strip layer-by-layer cumulative forming under the dynamic load exerted by electric control system, and the forming angle and precision of material after forming are guaranteed by fine adjustment sliding table and screw clamp, after forming is completed, pressure maintaining treatment is carried out by the pressure maintaining force of electric cylinder, material springback is reduced, and finally high-precision double-arrow-shaped metamaterial corrugated strip is obtained.

The invention provides a table structuring method and system based on merged cells in a text and line analysis PDF (portable document format), belongs to the technical field of document analysis and information extraction, and aims to solve the problem that the structures of the merged cells of the PDF table are difficult to keep in a retrieval enhancement generation process. Extracting a text block bounding box and drawing lines, and constructing a row-column grid; respectively calculating a transverse merge number and a longitudinal merge number according to the existence of a vertical line and a horizontal line at the boundary of the cell, and generating corresponding colspan and rowspan; and finally, outputting the HTML table containing the merged information for subsequent retrieval and generation. According to the method, wrong merging caused by matching only according to text content is avoided, and table semantic loss and data dislocation are reduced.
