Novel structure for artificial sunflower straw board and assembly method

Abstract

The invention provides a novel structure for an artificial sunflower straw artificial board and an assembly method. For the current situation that manual laying and assembly are used when whole straw is used as raw materials for producing artificial boards at the present stage in China, the novel inner-board structure and laying equipment which are suitable for mechanical assembly line laying are designed. The inner-board structure is characterized in that overall sunflower straw sheets are smoothed and laid and assembled in the form of a strip, all board blanks of which the thickness can be superposed and the length can be added are the boards of the longitudinal structure, the inner-board structure is more scientific and reasonable, in other words, the longitudinal strength is improved, and the transverse strength meets the standard; and the fracture surfaces of the four edges of the boards are more attractive, and the laying and assembly cost is lowered greatly due to the fact that a mechanical assembly line high in automation degree is developed by the inventor.

Description

Technical field: [0001] The invention discloses a novel structure and billet assembly method of a sunflower straw wood-based panel, which belongs to the field of straw wood-based panel manufacturing, and uses sunflower straw as a raw material instead of wood to produce a wood-based panel. Background technique: [0002] With the reduction of wood resources, the use of crop straw instead of wood to make wood-based panels has attracted the attention of many enterprises and scientific and technological personnel. However, it is very important to develop a technical method with high strength, low cost and adaptable to industrial production. At present, most enterprises are Still use the traditional method of crushing straw and mixing it with glue and then hot-pressing it. The strength of the board produced by this method is low, and its use is limited. In addition, the straw is manually assembled and assembled. The board produced by this method can meet the strength requirements. ...

AI Technical Summary

Problems solved by technology

[0003] The present invention is a technical method and special equipment for replacing manual pavement and assembly with a machine, aiming at the defects of the manual pavement and assembly technology in the production process of straw wood-based panels, and designs a machine suitable for mechanical paving. Plate structure, the feature of this new structure is that the whole stalks are arranged in one direction along the long strips, the thickness can be superimposed, and the length can be increased. The longitudinal strength of the plate produced is improved, and the transverse strength is not reduced. It is a brand-new plate type. At the same time, the process route and technical method are innovated. The defects of artificial paving and billeting have improved labor productivity, greatly reduced the production cost of the enterprise, and enabled the enterprise to realize large-scale industrial production, that is, it does not need to crush the straw without destroying the fiber structure of the straw, and does not need to add bamboo skin and steel mesh. And other materials, do not use wire ropes to weave into sheets, nor use three to nine pieces of cross-laying, nor use criss-cross blanking method, nor make curtains, but put the whole sunflower straw into the self-developed In the peeling machine, the half-breaking and skin core removal are completed at one time, and then the stalks are sizing. After sizing, the stalks are sent to the self-developed pavement assembly machine along the long strip, which is replaced by the pavement assembly machine. Manual paving and assembly, the paving machine works continuously, the workers only need to put the stalks into the feed port of the paving machine along the long strip, and after exiting the machine, a 1.3-meter-wide and infinitely long slab, the thickness of which is determined by the production The thickness of the sheet depends on the thickness of the sheet, the compression ratio is between 1:2.3 and 1:3.3, the length of the slab is determined by the specification of the sheet to be produced, and it can also be cut into 2.6 meters according to the standard specification, and then the slab is sent to the hot The press is heated, pressurized, solidified and shaped, and sawed to four sides to produce a new type of structural plate composed of vertical sunflower stalks.
