Abstract

The invention discloses a time-delay protection device for opening and stopping positions in a spinning workshop. The structure includes an AC power supply, a first circuit breaker and a first button. Open the auxiliary contact to input a negative pulse to the PLC input terminal, the output terminal of the PLC output terminal will act, the first relay will be closed, and the normally closed contact of the first relay will be disconnected. After the circuit timer in the PLC reaches the set time, the second When the first relay is disconnected, the normally closed contact of the first relay of the control circuit is closed, which acts as a power failure delay protection; after the first metering pump is started, the normally open auxiliary contact of the first contactor inputs a jump positive pulse to the input terminal of the PLC, and the PLC The output end acts, the second relay, the third relay and the fourth relay pull in, and the normally closed contacts of the second relay, the third relay and the fourth relay of the control circuit are disconnected, which acts as a delay protection for the opening position; Misoperation causes filaments to appear in the middle of the finished silk, which improves the beneficial effect of product quality.

Description

technical field [0001] The invention relates to the technical field of time-delay protection for opening and stopping positions, in particular to an additional time-delay protection device for opening and stopping positions in a spinning workshop. Background technique [0002] In the chemical fiber industry, filaments appearing in the middle of the finished yarn is a problem that cannot be eliminated. In addition to mechanical reasons, the misoperation of the operator is also an important factor for the production of filaments. After pressing the stop button by mistake, press the start button immediately. As long as this period of time is not too long, the finished yarn will not break. The test shows that: in the normal production process, after pressing the stop button for seven seconds, and then pressing the start button, the finished yarn will continue, and this section of finished yarn is in the inspection room. After testing, it was found that the thinnest part of the f...
