Detecting head for electronic yarn cleaner

Abstract

The invention discloses a detecting head for an electronic yarn cleaner. The detecting head comprises a button for intervention of an operator which has at least two states and a microprocessor; in the first state, intervention of the operator is not needed, and in the second state, intervention of the operator is expected; in the second state, if the touch button outputs a button triggering signal, the detecting head for the electronic yarn cleaner is switched to the first state; the button is a photoelectric touch button, and an optical receiver receives light, with a specific wavelength, emitted by an optical transmitting set and outputs an electric signal according to the received light; the microprocessor is connected to the optical transmitting set and the optical receiver, outputs a drive signal to the optical transmitting set, controls the optical transmitting set to emit light and outputs a button starting signal according to the electric signal sent from the optical receiver. The optical transmitting set cannot be lightened until the detecting head for the electronic yarn cleaner is in the second state and intervention of the operator is expected, and therefore the service life of the optical transmitting set of the touch button can be prolonged.

Description

technical field

[0001] The invention relates to an electronic yarn clearer, in particular to a detection head of the electronic yarn clearer. Background technique

[0002] The electronic yarn clearer is often configured on the yarn forming conversion equipment. It is the equipment for the last quality control process of the spinning enterprise's products, and it is also the equipment for the first quality control process of the raw materials of the weaving enterprise. The working performance of the electronic yarn clearer is directly Relates to yarn quality control and production efficiency.

[0003] Electronic yarn clearer is an electronic mechanical device for detecting and cutting yarn defects. The sensor converts the thickness change of the yarn into a corresponding electrical signal. After the signal is processed, the detection head (including the actuator) is controlled to cut off the yarn defects exceeding the set thickness (fineness) and length, and the removal will...
