Embodiment

[0028] A single-screw co-extrusion machine for processing profiles, its structure is as follows figure 1 As shown, it includes an extruding mechanism, a feeding mechanism, a driving mechanism, an up and down moving mechanism, a front, back, left and right moving mechanism and an electric control box 2. Among them, the extrusion mechanism includes a screw 11, a barrel 10, a heater and a cooling fan 8, and a hopper connecting seat 7. The screw 11 and the barrel 10 are socketed to form a material channel, and the heater and the cooling fan 8 are arranged on the barrel 10. The front end of the machine barrel 10 is also equipped with a machine head flange 9 , and the hopper connecting seat 7 is connected to the rear end of the machine barrel 10 . Feeding mechanism is made up of hopper 6 and hopper cover, and hopper 6 is connected on the hopper connecting seat 7, and hopper cover is located at the top of hopper 6. The driving mechanism includes a connecting shaft 18, a motor connec...

Abstract

The invention relates to a single-screw-rod co-extrusion machine for machining a section material. The single-screw-rod co-extrusion machine is composed of an extruding mechanism, a feeding mechanism, a driving mechanism, an up-and-down moving mechanism, a fore-and-aft left-right moving mechanism and an electronic control box. Compared with the prior art, the single-screw-rod co-extrusion machine provided by the invention has the effects that the yield, the rotation speed, the plasticization and deceleration motor power of the co-extrusion machine are perfectly balanced by selecting an optimized direct connection transmission system and adopting special screw rod structural design aiming at the working condition of the single-screw-rod co-extrusion machine for the section material; the stable metering extrusion is realized, and the single-screw-rod co-extrusion machine has the advantages that the energy is saved, the consumption is reduced, the service life is long, the real-time adjustment is convenient, the application range is wide and the like.

Description

technical field [0001] The invention relates to a single-screw co-extrusion machine, in particular to a single-screw co-extrusion machine for processing profiles. Background technique [0002] At present, the domestic profile co-extrusion machine is generally SJ 45-25 co-extrusion machine. The output of these co-extruders is generally large, often exceeding the output required for profile co-extrusion. Extruder overcapacity. The current common measure is to reduce the screw speed to control the output. The screw works at a low speed for a long time. However, there are plastic dispersion, distribution, inhomogeneity, plasticization and extrusion instability. Contents of the invention [0003] The object of the present invention is to provide a single-screw co-extrusion machine for processing profiles with energy saving, long service life, convenient real-time adjustment and wide range of application in order to overcome the above-mentioned defects in the prior art.
