Problems solved by technology

Generally, the PERT coil is 100-300 meters long, but it is not very stable during the production process
Due to the influence of many external factors, if you do not pay attention during the production process, the inner diameter of the finished product will be too small or even the pipe walls will stick together, which will eventually result in waste of materials, lower pass rate of finished products, and increase the cost of manufacturing.

Abstract

The invention provides an inner diameter detecting device for coil pipes. The inner diameter detecting device for the coil pipes comprises a base, a foundation ditch, an electromagnetic induction proximity switch, a magnet and a chain. The inward-recessed foundation ditch is formed in the center of the base, the electromagnetic induction proximity switch is arranged at the head end of the foundation ditch, the magnet is arranged at the tail end of the foundation bitch, and the chain matched with the foundation bitch is arranged in the foundation bitch. According to the inner diameter detecting device for the coil pipes, automatic detection and automatic alarming are synchronously conducted in the process of production, the structure is simple, the work efficiency is high, the quality of the finished products can be effectively monitored in real time, and waste caused by defective goods found after production is avoided.

Description

technical field [0001] The invention relates to an inner diameter detection device, in particular to an inner diameter detection device for coiled pipe products. Background technique [0002] PERT pipe is a kind of medium density polyethylene produced by special molecular design and synthesis process. It adopts the method of copolymerization of ethylene and octene, and obtains a unique molecular structure by controlling the number and distribution of side chains. While retaining the good flexibility, high thermal conductivity and inertness of PE pipes, PRRT pipes improve the heat resistance and pressure resistance of PE pipes, and can be used for long-term hot water transportation at 70°C. PRRT pipe retains the good flexibility and inertness of PE pipe, and at the same time has the advantages of low temperature resistance (-40°C), good impact resistance, better pressure resistance, non-toxic, tasteless, non-polluting, green and environmentally friendly, and recyclable. At t...
