Abstract

The invention relates to an automatic broken yarn lifting mechanism. The lifting mechanism comprises a square strip, wherein a motor is fixedly connected with the square strip via a motor box, two swing arms, which are grouped and are inverse in movement directions, are respectively connected with the two ends of the motor, and the motor and the swing arms form an active lifting system; a group of yarn stand fixed arms arranged at intervals are mounted on the motor box, yarn stand movable arms are movably connected with the yarn stand fixed arms to form a U shape, a plurality of bearing pieces are mounted at the end parts of the yarn stand fixed arms, and a winding shaft penetrates through each bearing piece to enable the yarn stand fixed arms to rotate relative to the winding shaft. The automatic broken yarn lifting mechanism is simple in structure and convenient to mount, the swing arms are driven by a power source to rotate, the swing arms are enabled to be in contact with the yarn stand fixed arms equipped with winding pipes, the yarn stand fixed arms are lifted under the action of transmitted force, and the problem that yarn on the surface of the winding pipe are worn and broken caused by empty friction between the winding pipes and the winding roller is avoided.

Description

A kind of broken yarn automatic lifting mechanism

Technical field

The present invention relates to textile machine equipment, relate in particular to a kind of broken yarn automatic lifting mechanism.

Background technology

At present, the number of spindles of existing spinning equipment is more, its quantity is not from 100 ingots to 1000 ingots etc., because being 24 hours, spinning equipment works long hours, in long spinning process, if generation broken yarn, need to prevent that workman from finding and connecing yarn in time, otherwise will cause that rolling tube is long-time to carry out sky with take up roll and rub, thereby the yarn on the rolling tube surface of grinding away, cause yarn cylinder surface " lousiness ", thereby bring loss to the product of factory, in order to find in time broken yarn situation, existing spinning equipment is all installed broken yarn indicating device, but this broken yarn indicating device can only remind textile worker occur broken yarn situation and connect yarn by warning lamp, can not take corresponding action to avoid above-mentioned rolling tube and take up roll to carry out the situation of empty friction, therefore in the urgent need to designing a kind of lifting mechanism that can automatically take corresponding actions to avoid yarn to be worn.

Summary of the invention

The applicant, for above-mentioned existing issue, is studied improvement, and a kind of broken yarn automatic lifting mechanism is provided, and having avoided reels closes the sky friction between take up roll, has improved yarn qualities, and has reduced manually connecing the dependence of yarn, has saved drainage of human resources.

The technical solution adopted in the present invention is as follows:

A kind of broken yarn automatic lifting mechanism, comprises square, and motor is affixed with square by motor box, and one group of direction of motion each other contrary two swing arms is connected with the two ends of motor respectively, and described motor and swing arm form active lifting system; One group of spaced apart bobbin cradle fixed arm each other is also installed on motor box, bobbin cradle lever arm is flexibly connected and forms with described bobbin cradle fixed arm " U " shape, in the end of described bobbin cradle fixed arm, multiple supporting members are installed, wireline reel runs through each supporting member makes described bobbin cradle fixed arm rotate with respect to wireline reel, and described bobbin cradle fixed arm, bobbin cradle lever arm, supporting member and wireline reel form passive lifting system.

Its further technical scheme is:

Described supporting member is " U " shape, has the installing hole for running through wireline reel on described supporting member;

Described motor is gear reduction synchronous motor;

Described bobbin cradle fixed arm have at least a side arm be positioned at described swing arm directly over.

Beneficial effect of the present invention is as follows:

The present invention is simple in structure, easy for installation, supply power source to drive swing arm to rotate by utilization, swing arm is contacted with the bobbin cradle bobbin cradle fixed arm that rolling tube is installed, make the lifting of bobbin cradle fixed arm by the transfer function of power, avoid occurring after broken yarn the empty friction of rolling tube and the take up roll problem of yarn on rolling tube surface that causes grinding away, greatly improve yarn qualities, and do not need by manually lifting rolling tube, greatly reduce the dependence to manually connecing yarn, save human resources, improved yarn qualities.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figure 1, a kind of broken yarn automatic lifting mechanism, comprises square 1, and motor 3 is installed in motor box 301 and is 1 affixed with square by motor box 301, and motor 3 is gear reduction synchronous motor.One group of direction of motion each other contrary two swing arms 2 is connected with the two ends of motor 3 respectively, motor 3 and initiatively lifting systems of swing arm 2 compositions; One group of spaced apart bobbin cradle fixed arm 5 each other is also installed on motor box 301, this bobbin cradle fixed arm 5 is for installing rolling tube 9, on bobbin cradle fixed arm 5, fix multiple supporting members 6 by securing member, supporting member 6 is " U " shape, on supporting member 6, have installing hole 701, wireline reel 7 runs through each supporting member 6 by installing hole 701 can rotate with respect to wireline reel 7 bobbin cradle fixed arm 5, and bobbin cradle fixed arm 5, supporting member 6 and wireline reel 7 form passive lifting system.As shown in Figure 1, bobbin cradle fixed arm 5 passes through the hinged formation of movable axis 801 " U " shape with bobbin cradle lever arm 8, bobbin cradle lever arm 8 can rotate certain distance with respect to movable axis 801, ensure rolling tube 9 can be fixed between bobbin cradle fixed arm 5 and bobbin cradle lever arm 8, bobbin cradle fixed arm 5 have at least a side arm 501 be positioned at swing arm 2 directly over.

Specific works process of the present invention is as follows:

As Fig. 2, shown in Fig. 3, silk thread is after two-for-one twisting spindles twisting, up by Pick Wire bar 15, order is through godet roller 14, porcelain rod 13, overfeeding roller 10, after moving a mouth 12, be wound on rolling tube 9, thereby drive rotation rolling tube 9 to rotate coiling silk thread by take up roll 4 frictions, in the time that silk thread breaks end, now porcelain rod 13 falls, because porcelain rod 13 is arranged on induction box 11, induction box 11 receives signal transmission of signal to motor 3, after starting, motor 3 controls two swing arms 2 swing in different directions, because a side arm 501 of bobbin cradle fixed arm 5 is positioned at directly over swing arm 2, therefore first swing arm 2 is upwards rotated 5 ° and is contacted with a side arm 501 of bobbin cradle fixed arm 5 from horizontal direction, then swing arm 2 continues upwards to rotate 22 ° and drive upwards lifting of bobbin cradle fixed arm 5, thereby rolling tube 9 is separated with take up roll 4, when bobbin cradle fixed arm 5 is lifted to after certain altitude, motor 3 quits work, because motor 3 adopts gear reduction synchronous motor, therefore motor shaft can bear certain moment of torsion and keep transfixion, thereby while providing abundant, chien shih weaving work connects yarn, after connecing yarn and completing, detect yarn repair signal by external sensor, utilize signal processing module (not shown, this signal processing module is existing known technology, this signal processing module is integrated in motor box 301) again control motor 3 and rotate backward 27 °, make swing arm 2 get back to initial position, and separate with bobbin cradle fixed arm 5 as shown in Figure 3, bobbin cradle fixed arm 5 is under Action of Gravity Field, automatically press down and contact with take up roll 4, recover spinning process.

More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of amendment.
