[0029] Through the above technical scheme, when in use, wood chips and thin slices can be conveyed to the feed hopper 1 by mechanical equipment for storage, and other fiber materials can be filled through the conveying pipe 4;The double screw feeder 2 conveys wood chips and thin slices to the mixing hopper 3 to mix with other fiber materials, and then conveys them through the single screw mixer 5, which not only realizes the mixing and conveying of multiple raw materials, but also realizes the quantitative conveying of raw materials, so as to strictly control the conveying process of raw materials and avoid the accumulation of raw materials, effectively reducing the labor degree of workers and improving the production efficiency of fiberboard.

[0030] In the embodiment, the double-screw feeder 2 comprises a conveyor shell 21, the inside of the conveyor shell 21 is provided with two first dragon rollers 22, the two first dragon rollers 22 are installed in cooperation with end plates at two ends of the conveyor shell 21 through belt bearing, and one end of the first dragon roller 22 penetrates to the outside of the conveyor shell 21 and is connected with a speed reducer 24 in cooperation; the speed reducer 24 is drivingly connected with a servo motor 23.

[0031] By adopting the above technical scheme, in use, the servo motor 23 transmits power to the speed reducer 24, the speed reducer drives the first dragon roller 22 to rotate, and the raw materials fall into the conveyor shell 21 from the feeding hopper 1, and are caused to fall from the material falling port 25 under the spiral pushing of the first dragon roller 22 and enter the mixing hopper 3.

[0032] Since the wood chips and the sheets are small block bodies, the spiral conveying through the two first dragon rollers 22 can realize quantitative conveying under the condition that the raw materials are not damaged, so as to ensure the conveying effect of the raw materials.

[0033] In the embodiment, the feeding hopper 1 is fixed above one end of the conveyor shell 21 close to the speed reducer 24; and the material falling port 25 is installed below the other end of the conveyor shell 21 away from the speed reducer 24.

[0034] Specifically, the material falling port 25 is an elastic compensator; and the material falling port 25 is connected with the mixing hopper 3 and the conveyor shell 21 through flanges.

[0035] In work, the double-screw feeder 2 and the single-screw mixer 5 may generate certain vibration; the material falling port 25 as the elastic compensator can play the role of elastic displacement compensation between the double-screw feeder 2 and the mixing hopper 3, so as to ensure the conveying effect of the raw materials.

[0036] In the embodiment, the longitudinal section of the conveyor shell 21 is arranged in a "W" shape and has two cavities for facilitating the rotation of the first dragon roller 22 and the conveying of the materials.

[0037] By adopting the above technical scheme, the accumulation of the raw materials at the dead angle of the conveyor shell 21 can be avoided, so as to improve the transmission efficiency of the raw materials.

[0043] The working principle of the utility model is as follows: in use, the servo motor 23 transmits power to the speed reducer 24, the speed reducer drives the first auger roller 22 to rotate, the raw materials fall into the conveyor shell 21 from the feeding hopper 1, and the raw materials fall from the dropping port 25 under the spiral pushing of the first auger roller 22 and enter the mixing hopper 3.

[0044] Since the wood chips and the sheets are small block bodies, the two first auger rollers 22 can spirally convey the raw materials, so that the raw materials can be quantitatively conveyed without being damaged, thereby ensuring the conveying effect of the raw materials; in work, the double-screw feeder 2 and the single screw mixer 5 may vibrate to a certain extent; the dropping port 25 is an elastic compensator, which can compensate the elastic displacement between the double-screw feeder 2 and the mixing hopper 3, thereby ensuring the conveying effect of the raw materials.

[0045] After the raw materials are mixed in the mixing hopper 3, the rotary motor 51 drives the second auger roller 52 to rotate, so that the raw materials are secondarily mixed and are spirally and quantitatively conveyed, which can ensure the sufficient mixing of the raw materials and the controllable conveying of the raw materials.
