Installing structure of forced side feeding machine of double-screw extruder

Abstract

The invention discloses an installing structure of a forced side feeding machine of a double-screw extruder. The installing structure comprises the forced side feeding machine, a forced side feeding machine side feeding cylinder is connected to a double-screw extruder side feeding cylinder body, the front portion of the side feeding cylinder is provided with a water inlet connector, a cooling water channel and a water drainage connector, a connecting flange at the rear end of the side feeding cylinder is connected to the front end face of a gearbox through a connecting body, the rear end face of the gearbox is connected to the front end face of a gear motor through the connecting flange, the bottom of the gearbox is installed on the upper portion of a feeding machine bottom plate, a sliding bearing is installed on the lower portion of the feeding machine bottom plate and installed on a sliding bearing sliding rod, and a limiting ring is installed on the sliding bearing sliding rod and fixed to the sliding bearing sliding rod through a fixing screw to limit a sliding bearing. According to the installing structure of the forced side feeding machine of the double-screw extruder, the problems that the forced side feeding machine side feeding cylinder is difficult to install, position and adjust, and the side feeding cylinder cannot be cooled through water, so that a feeding port sprays materials, and the gearbox is difficult to assemble and maintain are solved.

Description

technical field [0001] The invention relates to a twin-screw extruder, in particular to an installation structure for a forced side feeder of a twin-screw extruder. Background technique [0002] In the process of mixing and modifying polymer materials, the twin-screw extruder uses a forced side feeder to feed specific materials into the side feeding barrel of the twin-screw extruder according to the process requirements, and polymerizes The performance of the material can be improved by adding specific materials. After the polymer is blended and modified by adding specific materials, a polymer material that meets special needs and has higher performance can be obtained. [0003] The currently used twin-screw extruder forced side feeder installation structure has the following disadvantages: [0004] 1. The forced side feeder is installed on the cart, when connecting the forced side feeder to the side feeding barrel of the twin-screw extruder, it is necessary to adjust the s...
