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. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a yarn feeder based on gravity control comprises a fixed cross frame 1, a fixed shaft 2 is arranged in the middle of the inner cavity of the fixed cross frame 1, a feeding disc 3 is movably sleeved in the middle of the outer surface of the fixed shaft 2, a fixed block 6 is fixedly installed on the other side of the inner cavity of the fixed cross frame 1, a supporting slide bar 7 is pinned in the middle of the inner cavity of the fixed block 6, a fixed slide rail 8 is fixedly installed on one side of the top end of the fixed cross frame 1, the inside of the fixed slide rail 8 is fixedly connected with one end of the supporting slide bar 7 through a connecting pin shaft 9, the other side of the outer surface of the fixed shaft 2 is fixedly provided with a connecting bracket 10, the inside of the supporting slide bar 7 is provided with a connecting rope 11, one end of the connecting rope 11 is fixedly connected with one end of the connecting bracket 10 through a pulley which is in pin joint with the inside of the supporting slide bar 7, and the other end of the connecting rope 11 is fixedly connected with a counterweight pressing block 12 movably sleeved on one side of the outer surface of the supporting slide rod 7.

Wherein, to counter weight briquetting 12, connecting rope 11 and the setting between linking bridge 10 and the fixed axle 2, so that the last feeding disc 3 of fixed axle 2 under the pulling force of counter weight briquetting 12 gravity, can remain the trend of removing to fixed crossbearer 1 inner chamber one side all the time, so as to can keep the tension size of relatively stable to the yarn winding on feeding disc 3, compare with present yarn feeding device, adopt the design of mechanized structure, the problem that the in-process trouble risk ratio of having avoided accurate and complicated control unit to use for a long time is high and the configuration cost of using is higher, simultaneously, the control to yarn tension size is realized to the gravity of adopting counter weight briquetting 12, the higher problem of adoption motor adjustment control energy consumption has effectively been reduced.

In the technical scheme, the top end and the bottom end of the fixed shaft 2 are respectively provided with a sliding chute matched with the track of the inner wall of the fixed transverse frame 1.

The arrangement of the sliding groove on the fixed shaft 2 ensures that the sliding groove can drive the feeding disc 3 to slide left and right in the inner cavity of the fixed cross frame 1 under the influence of the gravity of the counterweight pressing block 12, and further ensures that the yarn feeding wound on the feeding disc 3 can keep stable tension.

In this technical scheme, one side fixed mounting of 2 surfaces of fixed axle has response probe rod 4, and the one end of response probe rod 4 cup joints with the inside activity of fixed mounting at the induction system 5 of 1 inner chamber one side of fixed crossbearer.

The sensing probe rod 4 and the sensing device 5 are arranged on the fixed shaft 2 and used for detecting and judging whether yarns on the feeder are broken or not, when the yarns are broken, the sensing probe rod 4 on the sensing probe rod can be driven to deviate towards one side of the inner cavity of the fixed cross frame 1 under the gravity of the counterweight pressing block 12, and meanwhile the sensing probe rod 4 on the sensing probe rod is driven to gradually separate from the sensing device 5, so that a feedback signal is sent to the driving control mechanism to stop driving and feeding the yarns.

In the technical scheme, the outer part of the fixed slide rail 8 is designed to be of a fan-shaped structure, and the size of an included angle between the support slide bar 7 and the fixed transverse frame 1 under the action of the fixed slide rail 8 and the connecting pin shaft 9 is controlled within the range of 0-90 degrees.

The arrangement of the support slide rod 7 and the connecting pin shaft 9 is convenient for adjusting the magnitude of the pulling force applied to the fixed shaft 2 and the counterweight pressing block 12 on the feed tray 3 by the gravity through adjusting the inclination angle of the support slide rod 7, as shown in fig. 4, when the inclination angle of the support slide rod 7 is alpha, the magnitude of the pulling force F can be known to be G × sian alpha through stress analysis and trigonometric function, and as can be known from fig. 5, the trigonometric function change curve of the sian alpha shows a gradually increasing trend when the angle is 0-90 degrees, so that under the condition that the magnitude of the gravity G of the counterweight pressing block 12 is not changed, the magnitude of the pulling force F can be adjusted through changing the angle alpha, the tension of the yarn on the feed tray 3 can be adjusted, and the feeder can be adapted to the yarns of different specifications and the required tension of the yarns.

In the technical scheme, a through groove penetrating to the upper end and the lower end of the supporting slide bar 7 is formed in the inner cavity of the supporting slide bar to ensure that the two ends of the connecting rope 11 can penetrate through the upper side and the lower side of the connecting rope.

The use method and the working principle of the embodiment are as follows:

firstly, the feeder is fixedly arranged on a feeding bracket of yarn through a fixed cross frame 1, then the yarn to be fed is wound on the outer surface of a feeding disc 3, and then the inclination angle of a supporting slide rod 7 is changed through a connecting pin shaft 9, so that the tension of a counterweight pressing block 12 on a fixed shaft 2 and the feeding disc 3 on the fixed shaft is equal to the tension required by the yarn wound on the feeding disc 3 through a connecting rope 11 and a connecting bracket 10 under the action of gravity, and then a feeding driving mechanism can be started to feed the yarn on the counterweight pressing block;

when the yarn wound on the feeding disc 3 is broken, under the action of the pulling force of the balance weight pressing block 12, the fixed shaft 2 can drive the feeding disc 3 on the fixed cross frame 1 to move to one side along the track of the inner wall of the fixed cross frame 1, and simultaneously drives the sensing probe rod 4 on the fixed shaft 2 to move, so that the sensing probe rod 4 and the sensing device 5 are separated from each other, and a feedback signal is generated to drive the feeding mechanism of the yarn to stop the drive feeding operation of the yarn.
