Embodiment Construction

[0018] The following further description with reference to the drawings does not limit the scope of the present invention.

[0019] See figure 1 with figure 2 As shown, in the barrel 5 of the feeding hopper of the wood-plastic extruder, two or more spiral trough slides 4 from top to bottom are provided, and the bottom of the spiral trough slide 4 is provided with a heating plate 11, The heating plate is controlled by a thermostat 3, and the thermostat 3 can control the heating plates 11 of a plurality of spiral trough slides 4 at the same time. The material is fed from the feeding port 2, and multiple feeding ports 2 can be set. The material slides down along the spiral trough 10. As it slides down, since the heating plate 11 works under temperature control conditions, the material on it slides down at the same time. It is heated, dehumidified and dried. When the two materials fall from the top to the bottom, they enter the mixing chamber 7. The mixing shaft 6 of the mixing cha...

Abstract

The invention relates to a novel mixing and material feeding structure. The structure includes a cylinder, a cover plate and a stirring and mixing chamber. The cylinder is cylindric. The cover plate is disposed on the upper surface of the cylinder. The cover plate is provided with a motor. The stirring and mixing chamber is disposed at the bottom in the cylinder. Stirring blades are disposed in the stirring and mixing chamber. A stirring shaft is disposed between the stirring blades and the motor. A spiral material chute path is disposed between the cover plate and the stirring and mixing chamber. The upper end of the spiral material chute path is connected to a feeding port. The lower end of the spiral material chute path is mounted at the upper part of the stirring and mixing chamber. Moisture removing, mixing, and material feeding blockage preventing are performed in a material feeding process, thus increasing quality and the efficiency of material feeding and avoiding a disadvantage that mixing inside an extruder is nonuniform.

Description

Technical field [0001] The invention relates to a feeding device, in particular to a novel mixed feeding structure. Background technique [0002] In the extrusion or injection process of plastic and its wood-plastic products, the material needs to be added to the plasticizing device of the extruder through a feeding hopper during plasticization. Due to the large friction coefficient of wood-plastic raw materials, feeding often occurs during the feeding process. The phenomenon of material blocking, and the material is placed for a long time, it is easy to absorb moisture, so that moisture is entrained in the material, so it needs to be dried before processing, otherwise it will produce bubbles during the processing. In addition, for wood-plastic extrusion, its mixing Uniformity is very important, but the mixing efficiency in the plasticizing device is very low due to the small space and high friction coefficient of the material. The above conditions have affected the quality, eff...
