Embodiment Construction

[0021] like figure 1 , a twin-screw extruder with a forced mixing structure includes: a motor (12) to control the rotation of a cylindrical device, a gear (11) connected to the motor, a gear (10) connected to a disc, a fixed cylindrical device The disc (5) of the device, the device (6) of the circular device connecting the disc, the blade mechanism (2), the inner cylindrical device (3), the outer cylindrical device (4), and the external impurity collector ( 9), bolts, nuts and washers (7).

[0022] like figure 1 , 2, 3, 4, the cylindrical device (3) (4) and the blade mechanism (2) are at the front end of the screw conveying section, when the twin-screw extruder is started, the inner cylinder is controlled at the same time The motors of the cylindrical device (3) and the outer cylindrical device (4) start to run to drive the inner cylindrical device (3) and the outer cylindrical device to work, and one motor can be used to control a cylindrical device alone, or a A motor and...

Abstract

The invention relates to an extruder and in particular relates to a double-screw extruder with a forced material mixing structure. A main design part of the double-screw extruder comprises a motor forcontrolling a cylindrical device to rotate, a gear connected with the motor, a gear connected with a round disc and the round disc for fixing the cylindrical device; the cylindrical device is connected with a sliding block of the round disc; an inner cylindrical device and an outer cylindrical device are cooperated to move, and impurities are discharged to an impurity collection device (9) of theouter part. After the impurities are stirred through a blade device (1), the impurities are finally pushed to a conveying section. By adopting a conveying part of the double-screw extruder with the structure, certain impurities with large grains can be discharged and materials are more uniformly mixed; material blocking is treated and the quality of an extruded product is improved.

Description

technical field [0001] The invention relates to a twin-screw extruder, in particular to a twin-screw extruder capable of uniformly mixing materials. Background technique [0002] The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, and extrusion stability, it has been widely used in extruded products. molding processing. Whether the mixing performance of the twin-screw extruder is uniform is one of the important criteria to measure the quality of the extruded product. For some granular materials, the existing twin-screw extruder has the following disadvantages: it is difficult to disperse evenly when the materials are mixed, the choice is single, and it cannot be produced for specific reinforcing materials. When the proportion of fillers or moisture is too high, A large amount of water vapor will be formed at the feeding port, making it difficult for th...
