Abstract

The invention relates to a temperature detection device for a heating plate of a thermoplastic pipe butt fusion welding machine. The temperature detection device comprises a temperature detection mechanism, a heating plate centering mechanism, a heating plate heating mechanism and a control system, the temperature detection mechanism comprises a sensor radial diffusion movement mechanism and a synchronous reverse movement mechanism, and the heating plate centering mechanism comprises a heating plate clamping mechanism and a locking mechanism. According to the temperature detection device, theautomatic temperature detection of the heating plate of the butt fusion welding machine is realized, the temperature measurement of heating plates of various sizes can be realized, instantaneity and the timeliness are realized in the temperature measurement process, data is more accurate and can be compared, and the temperature distribution condition on the working area of the heating plate can beaccurately described.

Description

technical field [0001] The invention relates to a temperature detection device, in particular to a temperature detection device for a heating plate used in a hot-melt butt welding machine. Background technique [0002] The hot-melt butt welding machine is a special welding equipment for welding thermoplastic pipe fittings using hot-melt butt welding technology. The heating plate is the main component that provides the heat source. Whether the surface temperature of the working area of ​​the heating plate meets the standard requirements and is evenly distributed , is a key factor affecting the quality of thermoplastic pipe butt joints. [0003] Clause 5.4.2 of GB / T 20674.1-2006 "Plastic Pipes and Fittings Polyethylene System Welding Equipment Part One: Hot Melt Butt Jointing" proposes that the temperature deviation in the working area of ​​the heating plate is "at an ambient temperature of -10°C to +40°C, at The temperature control system within the range of 170°C to 260°C s...
