Problems solved by technology
In the extrusion molding process, the heating function is generally provided by the hot pressing plate, but the heat transferred by the hot pressing plate is gradually exhausted from the outer circumference of the mold cavity to the center, and the heat is uneven, resulting in uneven heating of the extruded product during the molding process, and the hot pressing The temperature of the plate should not be too high, otherwise the glue will be pre-cured before extrusion, which will affect the strength of the product. Therefore, the heating of the hot pressing plate is slow and the production efficiency cannot be improved.

Embodiment Construction
[0022] Such as figure 1 As shown, the present invention includes a mold cavity 2 surrounded by a template 1, a gap 3 is provided on the template 1, and the gap 3 is opened on the template 1 around the mold cavity 2 for a week, and the gap 3 is filled with a microwave penetration plate made of ceramics 4. A microwave heating device 5 is installed outside the microwave penetration plate 4 .
[0023] The microwave heating device 5 is composed of a microwave tube 51 in the cavity and an anti-leakage baffle 52; the inner wall of the microwave penetration plate 4 is flush with the inner wall of the template 1, and the periphery of the outer wall is fixed on the outer wall of the template 1, and the anti-leakage baffle 52; the anti-leakage baffle 52 is fixedly connected to the formwork 1 by welding (connection holes can also be provided, and the connection can be fixed with bolts).
[0024] Anti-microwave leakage grooves 6 are provided on the inner wall of the mold cavity 2 at the f...

The invention discloses a plant fiber extruder with a microwave heating device, which comprises a die cavity surrounded by a die plate, a north is formed in the die plate and is filled with microwave penetrating plates, the microwave heating device is mounted outside the microwave penetrating plate which is made of ceramics, glasses or resins. According to the plant fiber extruder provided by the invention, microwave penetrates the microwave penetrating plates and enters into the die cavity to heat the materials inside the die cavity, heat is transmitted fast and uniformly, and the manufacturing efficiency is greatly improved.
Description
technical field [0001] The invention relates to the field of plant fiber extruders, in particular to a plant fiber extruder equipped with a microwave heating device. Background technique [0002] Plant fiber extruded products are formed by extruding fine wood fibers or crop straw fibers and glue. In the extrusion molding process, the heating function is generally provided by the hot pressing plate, but the heat transferred by the hot pressing plate is gradually exhausted from the outer circumference of the mold cavity to the center, and the heat is uneven, resulting in uneven heating of the extruded product during the molding process, and the hot pressing The temperature of the plate should not be too high, otherwise the glue will be pre-cured before extrusion, which will affect the strength of the product. Therefore, the heating of the hot pressing plate alone is slow and the production efficiency cannot be improved. [0003] As we all know, microwaves are very penet...
