Forming and extruding machine for quincuncial plastic pipe

Abstract

The invention discloses a forming and extruding machine for a quincuncial plastic pipe. The forming and extruding machine for the quincuncial plastic pipe comprises a machine body base, an extruding device, a machine mould head, an electronic control device, a heating device and a cooling device. The extruding device comprises a machine barrel which is arranged on the machine body base. A crushing and melting channel is arranged in the machine barrel and a screw capable of rotating at a high speed is arranged in the crushing and melting channel. A material feeding port is arranged in the front end of the machine barrel and a material discharging port is arranged in the other end of the machine barrel. The electronic control device comprises a main motor used for the rotation of the screw. The heating device consists of a plurality of electric heating plates which are arranged at the bottom of the machine barrel. The electric heating plates are arranged along the length direction of the machine barrel at intervals evenly and connected with the electronic control device respectively. According to the forming and extruding machine for the quincuncial plastic pipe, the heating efficiency on plastic materials can be effectively improved, the complete melting of the plastic materials can be guaranteed and the flowability of the molten plastic materials is good, so that the pushing and extruding effects of the forming and extruding machine on the plastic materials and good product quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of plastic pipe production, in particular to a quincunx-shaped plastic pipe forming extruder. Background technique [0002] In plastic extrusion molding equipment, the plastic extruder is usually called the main engine, and the subsequent equipment plastic extrusion molding machine is called the auxiliary machine. The forming principle of the plastic extruder is: through heating and pressurizing, the material is continuously formed through the outlet die in a flowing state, also known as "extrusion machine". However, most of the existing plastic extruders have unreasonable heating system structure and deviation of heating and melting effect, which leads to the problem that the pushing and extrusion of plastic are not smooth enough, especially for the extrusion of various types of special-shaped pipes. The production efficiency is low, and the qualified products are low. Plum-shaped plastic pipe is a quincu...
