Problems solved by technology

However, only one aspect of data can be detected, and in reality, the quality of PVC pipes includes many aspects
The PVC pipe mainly adopts the processing method of extruding the raw material after melting at high temperature. Affected by factors such as temperature and extrusion force, the precision of the shaping sleeve, etc., the PVC pipe has three aspects: outer diameter, wall thickness and out-of-roundness. Processing size accuracy will be reduced

Abstract

The invention discloses a detection system and a detection method for the extrusion size of a PVC pipe. The detection system comprises a fixed bracket fixedly mounted on a base, a probe holder arranged in a central through hole of the fixed bracket, a through hole formed in the central part of the probe holder for the PVC pipe to penetrate through, a water sprinkling device, a probe group distributed on the probe holder and an automatic opening and closing device. A transceiving integrated type ultrasonic sensor is utilized to detect the PVC pipe on line and receive the echo signal of the PVC pipe in real time, and then the echo signal is processed, so that the measurement data of the PVC pipe in the three aspects of outer diameter, wall thickness and out-of-roundness can be visually obtained. Detection is reliable, and efficiency is high. Online measurement is realized on the machining size of the PVC pipe in the three aspects of outer diameter, wall thickness and out-of-roundness, and the measurement data are timely fed back to a master control center for real-time adjustment, so that quality is ensured, and wastes are reduced.

Description

technical field [0001] The invention relates to pipe online detection equipment and methods, in particular to a PVC pipe extrusion size detection system and detection method. Background technique [0002] At present, PVC pipes have been used in all walks of life. Its anti-corrosion performance is good, it can withstand most acids and alkalis, and it can also replace steel pipes in some fields, so it has a good development prospect. What follows is that the production quality is not good enough, and there is a lack of effective online closed-loop detection method, which brings more waste of raw materials. [0003] Chinese invention patent application (application publication number CN103817908A, application publication date 2014.05.28) discloses an online monitoring device and method for unqualified PVC pipe bending. It includes the turning frame, the turning cylinder that controls the movement of the turning frame and the turning frame used to place the pipes after measurem...
