AI Technical Summary
Existing twin-screw extruder barrel processing equipment can only grind the end face of the barrel, but cannot effectively grind its outer and inner walls, resulting in a small grinding range and low efficiency.
A twin-screw extruder barrel processing equipment was designed. The outer wall of the barrel was polished by a rotating chuck and a grinding disc, and the inner wall of the barrel was polished by a grinding roller. The cooperation of the slide rail and the cylinder was used to achieve synchronous polishing of the inner and outer walls, thereby improving efficiency.
The inner and outer walls of the cylinder can be polished simultaneously, which significantly improves the polishing efficiency and meets the comprehensive processing requirements of the cylinder.

Description
Technical Field
[0001] The utility model belongs to the technical field of barrel processing equipment, in particular to a barrel processing equipment for a twin-screw extruder. Background Art
[0002] Based on the direction of the material flow and the angle between the centerline of the screw, the extruder can be divided into right-angled and beveled heads. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material and form it through the die. [2] Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and the less common multi-screw extruders and screwless extruders. The extruder barrel is a key component of the extruder. It works with the screw to complete the material conveying, plasticizing and extrusion process. During the production process of the extruder barrel, it is usually necessary to grind it.
[0003] For example, a processing device for the barrel of a twin-screw extruder with publication number CN213106030U has a swing cylinder mounting seat fixedly installed at the bottom of the workbench, a swing drive cylinder is hingedly connected to the swing cylinder mounting seat, the movable end of the swing drive cylinder is hingedly connected to a swing connection block, a mounting column is also fixedly installed at the bottom of the workbench, a push cylinder mounting plate is fixedly installed at the bottom of the mounting column, a push drive cylinder is fixedly installed on the push cylinder mounting plate, a push cylinder connection block is fixedly installed on the movable end of the push drive cylinder, and a roller connection assembly is fixedly installed on the push cylinder connection block. The utility model allows the barrel to be used after the steel pipe forming part is cut and then polished by the device, thereby reducing costs. At the same time, the device has a high degree of automation and only requires manual loading and unloading operations. If robots are used instead of manual loading and unloading, full automation can be achieved.
