An intelligent large-capacity extrusion molding unit

Abstract

The invention provides an intelligent high-capacity squeezing and molding machine set, belonging to the technical fueled of plastic molding machinery. The intelligent high-capacity squeezing and molding machine set comprises a controller, a charging device, an extruder, an injecting device and a transmitting device, wherein the controller comprises an automatic control system, an emergency stop switch, a variable frequency starter, an alarming buzzer and a thermoelectric couple. Compared with the conventional injection molding machine, the weight and the cost of the machine set can be respectively reduced by about 30%, the energy consumption can be reduced by about 40%, the shot capacity can be improved by 2-5 times, and the continuous extruding and casting can be carried out without stopping plastifying; and the production technology of products can be changed, and by adopting the technology of firstly plastifying plastic and finally adding filling auxiliary material, the filling auxiliary material can not be damaged, and the evenness of the added auxiliary material can be guaranteed, so that the functions of reinforcement and enhancement can be played, and a screw rod and a material cylinder of equipment can not be worn.

Description

technical field [0001] The invention relates to an intelligent large-capacity extrusion molding unit, which belongs to the technical field of plastic molding machinery. Background technique [0002] With the development of the global economy, the application fields and the number of applications of plastics continue to grow at a relatively high rate. At the same time, waste plastics are also spread all over the world, causing more and more pollution to the environment. At present, countries all over the world have carried out various measures against white pollution. Among them, plastic wood products produced from waste plastics and wood powder are being promoted in large quantities all over the world. Blending and granulation, and then using an extruder to extrude the profile, the result is that the product does not play its role, the cost is high, the strength is low, and it cannot be widely used in the market. In addition, the plastic and wood flour are co-extruded, and t...

Problems solved by technology

At present, countries all over the world have carried out various measures against white pollution. Among them, plastic wood products produced from waste plastics and wood powder are being promoted in large quantities all over the world. Blending and granulation, and then using an extruder to extrude the profile, the result is that the product does not play its role, the cost is high, the strength is low, and it cannot be widely used in the market. In addition, the plastic and wood flour are co-extruded, and the wood fiber is destroyed by the friction of the screw. The strength of wood powder can only play the role of filling, not only failed to play the role of reinforcement, but caused great wear and tear on the screw and barrel of the extruder, reducing the service life of the screw, thus restricting the plastic products Wider promotion and application

Due to the advantages of high strength, good toughness, no deformation, no layer opening, no aging, non-toxic and tasteless, and can be sawed and nailed, plastic products are widely used in industry, agriculture, national defense, logistics, construction, municipal and other fields. Due to the limitation of its own mechanism, the traditional injection molding machine cannot complete the throughput of plastic rib raw materials, which limits the use of plastic rib products
