Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Example one

Referring to fig. 1-4, a wire feeding self-stop device, includes base 1, be fixed with an installation section of thick bamboo 2 on base 1 and be used for vertically placing the bobbin that the winding has the yarn, be fixed with the level above an installation section of thick bamboo 2 (through the bracing piece) and set up stand pipe 3, set up the wire guide on the stand pipe 3 and be used for the yarn on the bobbin to pass, correspond 3 spaced apart wire guide 6 that are provided with of stand pipe, be provided with line hole 61 on the wire guide 6 and be used for further steady wire, wire guide 6 is fixed through two spaced horizontal installation pole 4 that set up, correspond installation section of thick bamboo 2 has installed distance measuring sensor 5 on base 1 for detect the yarn thickness on the bobbin, when being less than preset yarn thickness, distance measuring sensor 5 in time moves and carries out information feedback.

The distance measuring sensor 5 selects an infrared distance measuring sensor, after the infrared distance measuring sensor is connected with the controller, the distance between the bobbin and the distance measuring sensor 5 is increased by setting the fed back distance numerical range when the yarn is unwound from the bobbin, and the controller acts to alarm or cut off the working power supply after the distance of the infrared distance measuring sensor reaches the set maximum critical value. The above-mentioned conventional technical means using the scene as an infrared distance measuring sensor is not described herein again.

In addition, in order to timely act and play a role in balancing tension when yarn is broken, an adjusting plate 7 is rotatably connected to the yarn guide 6 through a rotating shaft 71, the adjusting plate 7 rotates downwards after yarn is broken to shield the distance measuring sensor 5, and a through hole (a thread hole) through which the yarn passes is formed in the adjusting plate 7.

In particular, the method comprises the following steps of,

the rotating shaft 71 is arranged deviating from the center of the adjusting plate 7 to reserve a shielding surface, and the through hole is arranged on the side surface of the rotating shaft 71; a torsion spring 72 sleeved on the rotating shaft 71 is arranged between the adjusting plate 7 and the thread guide 6, of course, mounting holes of the torsion spring 72 are formed on the opposite surfaces of the adjusting plate 7 and the thread guide 6 for assembling the torsion spring 72, and the torsion spring 72 is in a moderate torsion state so as to keep the support of the adjusting plate 7 and balance the acting force of the yarn.

When the yarn is broken, the torsion spring 72 enables the adjusting plate 7 to reset downwards to shield the distance measuring sensor 5, and the distance is lower than the set minimum distance; of course, in order to perform the positioning function, as shown in fig. 1 and fig. 3, an abutting block 73 is fixed at the end of the rotating shaft 71 extending out of the wire guide 6, and a limit block 62 is correspondingly arranged on the wire guide 6, and the abutting block 73 and the limit block 62 form an included angle of about 90 °.
