Time controlling device for fast heating soldering iron

Abstract

The invention relates to a time controlling device for fast heating soldering iron. The time controlling device comprises a single-chip microcomputer, a power supply control circuit, a signal control circuit and a signal sampling circuit, wherein the single-chip microcomputer is used for carrying out closed-loop control over the sampling time and time-out control over the feedback time on the fast heating soldering iron. The power supply control circuit is used for controlling the on-off state of a switching power supply, the signal control circuit is used for preventing the single-chip microcomputer from outputting an abnormal signal, and the signal sampling circuit is used for sampling the voltage of a working signal sent by the switching power supply to the fast heating soldering iron and converting the working signal into a sampling time signal to be fed back to the single-chip microcomputer. By means of the time controlling device, the stable work of the fast heating soldering iron can be effectively guaranteed, closed-loop control is adopted, error compensation control is precise, working efficiency is high, the waste of strapping belts is reduced, and meanwhile dangers caused by the abnormity of the single-chip microcomputer or the loss of control of a fast heating load in the process of working are avoided.

Description

technical field [0001] The invention relates to a fast-heating soldering iron in a tie-bar machine, in particular to a fast-heating soldering iron time control device used in financial equipment. Background technique [0002] The bank system of our country mainly adopts the automatic binding machine to bind and bundle 100 banknotes. At present, the binding machine generally uses a fast heating iron without preheating. The quality of sticking and cutting affects the binding effect of banknotes. The transformer controls the fast heating soldering iron, and its temperature will change with the change of the mains power supply voltage. In the past, the heating gear was adjusted manually according to the sticking effect. First, the operation is troublesome, because the mains power supply voltage fluctuates, and some The regional voltage fluctuates greatly, which requires the operator to adjust the heating gear frequently according to the sticking and cutting effect; secondly, it ...
