Plasticizing extruder for waste rubber and plastic molten recovery materials

Abstract

The invention aims to provide a plasticizing extruder for waste rubber and plastic molten recovery materials. The plasticizing extruder for the waste rubber and plastic molten recovery materials comprises a cylinder body provided with a feeding inlet and a cylinder body heating device, two spiral pushing rods provided with spiral blades, two spiral pushing rod rotating driving devices, a front mounting plate arranged at the front end of the cylinder body and provided with a front sliding hole and a front sliding column located in the front sliding hole, a rear mounting plate arranged at the rear end of the cylinder body and provided with a rear sliding hole and a rear sliding column located in the rear sliding hole, a filter discharging device arranged at the front end of the cylinder body, a distributing device arranged at the front end of the filter discharging device, and a pushing rod axial moving device. The two ends of the first spiral pushing rod are in pivot connection with thefront sliding column and the rear sliding column in a one-to-one-correspondence mode; the two ends of the second spiral pushing rod are in pivot connection with the front mounting plate and the rearmounting plate in a one-to-one-correspondence mode; the front mounting plate is provided with a first discharging hole set; and the front sliding column is provided with a second discharging hole set.Regenerated rubber and plastic manufactured by the plasticizing extruder for the waste rubber and plastic molten recovery materials are good in strength and toughness.

Description

technical field [0001] The invention relates to the field of rubber and plastic processing, in particular to a plasticizing extruder for melting recycled waste rubber and plastic. Background technique [0002] The invention of Chinese patent application number CN 201510694544.7 discloses a waste rubber and plastic toughening equipment, including a frame with a hopper; the waste rubber and plastic toughening equipment also includes: a feed port connected to the outlet of the hopper The toughness enhancing device is a vacuum degassing device connected to the inlet of the toughness enhancing device. The traditional waste rubber and plastic toughening equipment has the disadvantage of poor strength and toughness of the regenerated rubber and plastic. Therefore, a kind of waste rubber and plastic melting recycled plastic is designed to produce the regenerated rubber and plastic. Chemical extruder has become an urgent problem to be solved. Contents of the invention [0003] Th...
