Pipe end sealing equipment for steel-plastic composite pipe and using method of pipe end sealing equipment

Abstract

The invention relates to the technical field of sealing of a polyethylene composite pipe, in particular to pipe end sealing equipment for a steel-plastic composite pipe and a using method of the pipeend sealing equipment. The pipe end sealing equipment comprises a base and a fixed seat, wherein the fixed seat is fixedly connected to the rear side of the top end of the base, a third motor is fixedly connected to the inner side of the left end of the fixed seat, a second lead screw is fixedly connected to the tail end of a spindle of the third motor and is rotationally connected with the fixedseat, and a first slider is spirally connected to the outer side of the second lead screw. According to the pipe end sealing equipment, a supporting seat, a cutter, a second motor, the slider and a fourth motor are arranged, the cutter can cut a composite pipe orifice without manual work, besides, a heating plate can heat the composite pipe and a sealing ring simultaneously, the heating time is saved, the working efficiency is improved, meanwhile, under actions of a first lead screw and the second lead screw, the composite pipe and the sealing ring can be mutually extruded and attached to eachother, the equipment is simple to operate, and the sealing rate and the product qualification ratio are increased.

Description

technical field [0001] The invention relates to the technical field of polyethylene composite pipe sealing, in particular to a pipe end sealing device for a steel-plastic composite pipe and a use method thereof. Background technique [0002] Compared with plastic pipes, perforated steel belt composite pipes have higher rigidity and impact resistance. They are not only suitable for direct burial, but also meet the needs of overhead laying. They are widely used in heating, water supply, gas, mining, chemical industry, and agricultural irrigation. In the field of chemical liquid transportation and other fields, the perforated steel belt composite pipe is a composite pipe made of steel pipe as the skeleton and compounded with thermoplastic polyethylene. [0003] The continuous formed perforated steel strip composite pipe needs to be cut off according to a certain length, and the perforated steel strip at both ends is exposed. In order to ensure the performance of the perforated ...

AI Technical Summary

Problems solved by technology

[0003] The continuous formed perforated steel strip composite pipe needs to be cut off according to a certain length, and the perforated steel strip at both ends is exposed. In order to ensure the performance of the perforated steel strip composite pipe, the port needs to be sealed, and at present, the manual method is generally used It is carried out with the injection molding method, that is, the port of the composite pipe is manually sealed by a manual welding torch. The sealing method takes a long time, has low efficiency, and poor quality. Therefore, a pipe end sealing device for steel-plastic composite pipe and its use method are proposed to solve the above problems.
