Description

Technical Field

[0001] The invention relates to the technical field of straw fiberboard, in particular to an integrated straw high-density fiberboard and a drying and pressing device thereof. Background Art

[0002] Straw fiberboard uses crop straw as the main raw material, which is abundant and cheap. Its production process can effectively reduce pollutant emissions and forest resource consumption, and meets the requirements of modern society for green building materials. Straw fiberboard has strong pressure resistance, bending strength and good sound absorption and noise reduction, so it is suitable for construction and decoration.

[0003] For example, a Chinese patent with authorization announcement number CN204914748U discloses an environmentally friendly straw fiberboard, including a surface functional layer, a first wood pulp fiber layer, a first adhesive layer, a straw fiber layer, a second adhesive layer, and a second wood pulp fiber layer. The fiberboard comprises a first wood pulp fiber layer, a straw fiber layer, and a second wood pulp fiber layer from top to bottom. The first wood pulp fiber layer and the straw fiber layer are bonded by the first adhesive layer, and the second wood pulp fiber layer and the straw fiber layer are bonded by the second adhesive layer. The contact surfaces of the first adhesive layer, the second adhesive layer and the straw fiber layer are zigzag. The surface functional layer is sprayed on the upper surface of the first wood pulp fiber layer and the lower surface of the second wood pulp fiber layer.

[0004] However, there are still some problems in the above patent. Since the existing straw fiberboard has poor hardness, a protective layer needs to be pasted on its long and wide surfaces. The existing protective layers are installed by setting glue. Although this method can protect the fiber layer, it is difficult to replace the protective layer when it is damaged. At the same time, since the two are connected by glue, glue will remain on the fiberboard, affecting the subsequent adhesion effect of the fiberboard.

[0005] Therefore, how to complete the replacement of the protective layer is a problem that needs to be solved at present. Summary of the invention

The side has an arc-shaped structure; by making the top of the connecting rod 86 higher than the top of the chain transmission device 82 and making the first guide roller 88 located below the chain transmission device 82, the limiting belt 812 between the first guide roller 88 and the second guide roller 89 is set at an angle, so that the limiting belt 812 can make the fiberboard 1 separate from the chain transmission device 82 and be fixed on the transportation part 87, and the supporting roller 874 on the loading tray 871 can not only support the fiberboard 1, but also support the limiting belt 812 when the supporting roller 874 is not in contact with the fiberboard 1, so that the limiting belt 812 can complete the support and limiting work of the fiberboard 1.

[0034] Working principle: when the protective layer 3 needs to be replaced, the connecting bolt 26 is rotated forward and disassembled, and then the protective layer 3 is pulled to move the protective layer 3 between the fixed frame 21 and the sliding frame 22, and the old protective layer 3 is disassembled. Then, the protective layer 3 is installed at a predetermined position by the above method, and the position of the sliding frame 22 is adjusted to make the screw holes on the sliding frame 22, the fixed frame 21 and the protective layer 3 coaxial. At this time, the fixing work of the three is completed by the set connecting bolt 26, and the installation and replacement of the protective layer 3 is completed; The straw fibers are placed in the processing area of ​​the water removal unit 4 by means of a conveyor. At this time, the distance between the two pressing rollers 442 is changed by the operation of the adjusting component 45. At the same time, the water removal work of the straw fibers is completed by means of the pressing roller component 44. The dehydrated straw fibers are then transported to the breaking unit 5 by means of another conveyor. After being transported to the breaking unit 5 by another conveyor, the two separation wheels 54 rotate, thereby driving the protrusions 55 to rotate, so that the pressed straw fibers can be broken up and transported to the straw remover 61 in the drying unit 6, and then the straw remover 61 breaks them up again and passes them through the drying chamber 63 to complete the heating and drying work; After the straw fibers are pressed and formed to form a fiberboard 1, the fiberboard 1 is transported to the loading section 84 along the chain transmission device 82. At this time, the retaining spring 832 in the loading section 84 gradually reduces the distance between the fiberboard 1 and the fiberboard 1 and abuts against the fiberboard 1 in the moving direction thereof, thereby limiting the position of the fiberboard 1. Then, the transport section 87 and the clamping section are used in coordination to enable the fiberboard 1 to rotate along the transport section 87 and be located in a predetermined deburring area. The fiberboard 1 is deburred by rotating the cutting member 85 and is discharged from the unloading section 83 along the transport section 87 to complete the deburring of the fiberboard 1.
