Automatic temperature control system for plastic welder

Abstract

The invention discloses an automatic temperature control system for a plastic welder. The automatic temperature control system comprises a working parameter detecting unit which detects associated working parameters of an ultrasonic-wave generating device for the plastic welder, a controller for controlling the ultrasonic-wave generating device, a temperature estimating module for estimating hot-melting temperature of a welded region according to the information detected by the working parameter detecting unit, a temperature detecting unit for detecting surface temperature of a welded plastic product on the peripheral side of the welded region, a position detecting unit for detecting the position of the temperature detecting unit, a temperature ultra-limit judging module for judging whether the welding temperature under the current state exceeds the limit, a parameter input device, an alarm prompting unit and a display. The automatic temperature control system has a rational design, a simple operation and good using effects, a high intelligent degree, can solve the defects such has poor welding quality, easily caused temperature distortion to other non-welded regions of the welded plastic product, inconvenience to operation control, and the like of an existing plastic welder.

Description

technical field [0001] The invention relates to an automatic temperature control system, in particular to an automatic temperature control system for a plastic welding machine. Background technique [0002] Nowadays, the replacement of metal materials by plastics has become the trend of technological development in various industries. The plastic welding machine for plastic welding has become an indispensable assembly machine for plastic products. The early joining of plastics was glued, solvent or electric heating. , the above-mentioned connection methods all have phenomena such as low efficiency and easy aging of the contact surface to varying degrees. The application of ultrasonic plastic welding machines solves the above problems and promotes the development of the plastic industry. Ultrasonic plastic welding machine uses the energy conversion system to convert high-frequency electronic energy into high-frequency mechanical vibration, which is transmitted to the plastic...
