Problems solved by technology

[0003] At present, most of the inlet and outlet ends of twin-screw extruders on the market are simple and fixed in structure, and the materials at the inlet and outlet ends cannot be filtered and screened as required. At the same time, the loading and unloading operations of the inlet and outlet hoppers also need professional tools to complete, resulting in troublesome maintenance. The cost of use is relatively high, and the number of its feed hoppers cannot be changed according to needs, making its scope of application relatively single and limited

Abstract

The invention discloses a double-screw extruder. The double-screw extruder comprises a transverse main machine frame, a transverse extrusion bin arranged on the transverse main machine frame and two extrusion screws rotationally arranged in the transverse extrusion bin, wherein a right arc-shaped adjusting groove and a left arc-shaped adjusting groove are formed in the two sides of the transverse extrusion bin respectively; and the right arc-shaped adjusting groove and the left arc-shaped adjusting groove are each provided with a top feeding port, arc-shaped quick-release filtering devices are arranged in the right arc-shaped adjusting groove and the left arc-shaped adjusting groove in a sliding manner, and a front quick-release filtering device is arranged at the front end of the transverse extrusion bin. The feeding ports are installed through the arc-shaped quick-release filtering devices, the right arc-shaped adjusting groove and the left arc-shaped adjusting groove, a discharging port is installed through the front quick-release filtering device, materials are added into the transverse extrusion bin of the double-screw extruder through the top feeding ports, the extrusion screws conduct extrusion, and by sliding the arc-shaped quick-release filtering devices and the front quick-release filtering device, an external feeding hopper and an external discharging hopper can be quickly detached, so that the later maintenance efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of molding processing machinery, in particular to a twin-screw extruder. 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. [0003] At present, most of the inlet and outlet ends of twin-screw extruders on the market are simple and fixed in structure, and the materials at the inlet and outlet ends cannot be filtered and screened as required. At the same time, the loading and unloading operations of the inlet and outlet hoppers also need professional tools to complete, resulting in troublesome maintenance. The cost of use is relatively high, and the number of its feed hoppers cannot be changed according to needs, so that its scope of application is relatively single a...
