Polyurethane pipe extrusion modeling system

Abstract

The invention discloses a polyurethane pipe extrusion modeling system. The polyurethane pipe extrusion modeling system comprises an extruder, a water tank for cooling, a dragger for dragging and straightening, a cutting frame for cutting off and a collecting box located at the tail end of the cutting frame, wherein the extruder, the water tank, the dragger, the cutting frame and the collecting box are sequentially connected. The polyurethane pipe extrusion modeling system is characterized in that a vacuum sizing box is arranged between the extruder and the water tank, supporting wheels and guiding wheels used for supporting and guiding pipes after being sized are arranged between the vacuum sizing box and the water tank, and the structure of the polyurethane pipe extrusion modeling system is out of the ordinary, an original integrated mode of the water tank and a vacuum sizing unit is changed by the polyurethane pipe extrusion modeling system, and the vacuum sizing box is singly arranged and located between the extruder and the water tank, so that the defects of the pipes which comes out of the vacuum sizing box are convenient to observe in time, and the extruder is further convenient to adjust; and the problem of the high rejection rate is avoided, simultaneously efficiency is improved, and production cost is reduced.

Description

Technical field [0001] The patent of the present invention relates to the technical field of pipe production and processing, in particular to an extrusion molding system for extrusion molding processing of polyurethane pipes. Background technique [0002] Extrusion molding is one of the important molding methods in the processing of plastics and polymer materials. It occupies an important position in pipe molding. Most thermoplastic materials can be processed by extrusion molding. Extrusion molding has the following characteristics: the molding process is continuous, so its production process is generally continuous, its production efficiency is high, the application range is wide, the investment is small, and the effect is quick. [0003] Polyurethane pipes have many excellent characteristics, including: wide adjustable range of performance, strong adaptability, good wear resistance; high mechanical strength; good bonding performance; good elasticity, excellent recovery, good low ...

AI Technical Summary

Problems solved by technology

[0004] The current polyurethane pipe forming system is generally composed of an extruder, a cooling and setting machine, a tractor, a cutting machine and a receiving device connected in sequence. The high-heat pipe extruded by the extruder is directly sent into the cooling and setting machine. Cooling and setting treatment at the same time, however, since the cooling and setting machine is generally composed of a long cooling water tank and a vacuum rating mechanism, the high-heat pipe travels a long distance in the cooling and setting machine. In some cases, it can only be seen after coming out of the cooling and setting machine. At this time, the defective pipe has been extruded for a long distance from the extruder. When the operator sees the defect from the exit of the cooling and setting machine, he will go Adjust the parameters of the extruder, so that defects cannot be seen directly from the exit of the extruder, and the parameters of the extruder cannot be adjusted in time, resulting in a lot of waste of formed pipes, time-consuming, wasteful work, high rework rate, and low efficiency.
