Steel-plastic composite pipe port middle layer metal steel wire injection molding edge sealing device and method

Abstract

The invention discloses a steel-plastic composite pipe port middle layer metal steel wire injection molding edge sealing device. The steel-plastic composite pipe port middle layer metal steel wire injection molding edge sealing device comprises a fixing disc, an outer protective barrel is coaxially fixed to one circumferential side face of the fixing disc, a material conveying barrel is coaxially fixed in the outer protective barrel, a material conveying screw is coaxially installed in the material conveying barrel, a constant-speed motor is coaxially fixed to the other circumferential side face of the fixing disc, the output end of the constant-speed motor is coaxially and fixedly connected with one end of the material conveying screw, a nozzle is arranged at the other end of the material conveying barrel, an annular heater is arranged on the outer side wall of the material conveying barrel, a feeding hopper is fixed to the side wall of the outer protective barrel, the discharging end of the nozzle is fixedly connected with a pipe edge sealing mold, a limiting forming ring groove is formed in the other side face of the pipe edge sealing mold, and a steel-plastic composite pipe is in butt joint with the limiting forming ring groove. The invention has the technical effects of being integrally formed through mold injection molding, being time-saving and labor-saving, being easier to realize automatic operation, being simple and convenient in operation method, and ensuring the edge sealing quality.

Description

technical field [0001] The invention relates to the technical field of injection molding edge banding devices, in particular to an injection molding edge banding device and method for metal steel wires in the middle layer of a steel-plastic composite pipe port. Background technique [0002] Steel-plastic composite pipe, also known as steel mesh skeleton polyethylene composite pipe, steel skeleton polyethylene composite pipe, is a new type of pipe with the characteristics of pressure resistance, corrosion resistance and light weight. The bare leakage is outside, without port edge sealing treatment, not only will not have the effect of high pressure resistance, but if the exposed state is too long, it will easily corrode and rust, reducing the service life. Therefore, the edge needs to be sealed with PE plastic when leaving the factory. The previous production process Through the hot-melt sealing ring, it is manually placed on the edge of the pipe, and it is time-consuming, ...

[0002] Steel-plastic composite pipe, also known as steel mesh skeleton polyethylene composite pipe, steel skeleton polyethylene composite pipe, is a new type of pipe with the characteristics of pressure resistance, corrosion resistance and light weight. The bare leakage is outside, without port edge sealing treatment, not only will not have the effect of high pressure resistance, but if the exposed state is too long, it will easily corrode and rust, reducing the service life. Therefore, the edge needs to be sealed with PE plastic when leaving the factory. The previous production process Through the hot-melt sealing ring, it is manually placed on the edge of the pipe, and it is time-consuming, laborious and inefficient through complex processes such as cooling and pressure maintaining.
