Especially, in knitting machine, must regulate Yarn braking effect and described braking effect very exactly and only produce by the axial contact pressure of several grams.
Yarn arresting gear B has the free-ended fixed support portion 6 that is installed to or is integrated into housing arm 2.Support portion 6 accommodates the quick adjustment parts Q that is used for regulating the adjusting parts E of braking effect gradually and is used for moving with big stroke the internal part of support portion 6, with inboard or the smaller diameter end of brake body 5 and the zone between the support portion 6 that for example can touch brake body 5, for example be used for maintenance program, cleaning course or replacing brake body 5 or new yarn is passed yarn arresting gear B.In the illustrated embodiment, regulate parts E, Q and have common driving element 7, rotation pull-button 19, in described rotation pull-button, thread guide elements 8 is installed.Rotation pull-button 19 selectively is rotated to drive adjusting parts E or axially to be pulled out from support portion 6 to drive quick adjustment parts Q.The pull-type Zhu Pao (pull bead) 10 that the periphery of rotation pull-button 19 can be provided with the handgrip element that is used to rotate 9 of circle distribution and be used for extending at least one circumference of pulling (pulling action).Rotate pull-button 19 even can manually be pushed and get back to the original position that illustrates.6 the lower area in the support portion (lower region) is provided with the transparency cover 11 of signal lamp.Yarn feeder F can be installed on the not shown bearing structure by the fixed part (fixation) 12 of housing 1.
For example Fig. 2 is the horizontal axis profile of yarn arresting gear B that for example is used for the Yarn feeder F of Fig. 1.Conical brake body 5 has smaller diameter end 13, and described smaller diameter end preferably is fixed between interior ring 14 of infundibulate and the L shaped outer shroud 15 loosely. Ring 14,15 clampings each other expediently (snap connection).Interior ring 14 has convexly curved inner surface 16 so that similar universal joint ground combines with the cylindrical positioning end (positioning end) 17 of unwinding yarn pipe 18, and described unwinding yarn pipe definition is by the axial yarn path of yarn arresting gear B.Interior ring 14 is arranged on the positioning end 17 loosely, just has radial clearance.The permanent magnet device P1 of outer shroud 15 carrying brake bodies 5, the permanent magnet rings of the single permanent-magnet block of several circle distribution or circumference extension just.Driving element 7 just rotates on the free end that pull-button 19 is connected to unwinding yarn pipe 18, preferably with unwinding yarn pipe 18 one, and is positioned on the free end away from the support portion 6 of brake body 5.
Unwinding yarn pipe 18 is provided with external screw-thread (thread) 18a, its can with the permanent magnet device P2 screw-threaded engagement of support portion 6.Permanent magnet device P2 can also by the single magnet piece of a plurality of circle distribution or shown in the permanent magnet rings that extends of circumference constitute.The permanent magnet device P2 of support portion 6 is fixed in the holding ring 20, preferably is glued to holding ring 20.Holding ring 20 has the U-shaped cross section and meshes the interior internal thread 21 of pitch of the external screw thread 18a of unwinding yarn pipe 18.Permanent magnet device P1, P2 magnetize with opposite polarity, make described permanent magnet device mutually exclusive in the axial direction.The repulsive force of smaller diameter end 13 that imposes on brake body 5 is by regulating parts E by changing the axial distance between permanent magnet device P1, the P2, just in the illustrated embodiment, the position-adjustable to axial of the permanent magnet device P2 by changing the support portion 6 in the support portion 6.
By the unshowned adjacently situated surfaces of stopping element 23 or by tubular shell 24, holding ring 20 is prevented from relative housing 28 rotations, makes that holding ring 20 only can be axially displaced based on the rotation of unwinding yarn pipe 18.
Unwinding yarn pipe 18 has peripheral circumferential groove 22.Annular stop element 23 is inserted in the groove 22.Stopping element 23 for example can be the split ring of similar western lattice ring (Seeger ring).The end that illustrates of stopping element 23 qualification permanent magnet device P2 is the position to axial, and it is positioned at the side away from the holding ring 20 of brake body 5.
In the position that illustrates of the parts of yarn arresting gear B, tubular shell 24 is around permanent magnet P1, P2 and unwinding yarn pipe 18.The front end 25 of tubular shell 24 leaves radial clearance ground around outer shroud 15.Tubular shell 24 has the flange that extends internally 26 at rear portion, and the rear side of described flanges abut stopping element 23 is with respect to unwinding yarn pipe 18 axial location tubular shells 24.The periphery carrying of tubular shell 24 is several, the pin 27 of circle distribution, and the axle that each pin is basically parallel to unwinding yarn pipe 18 extends.Described axle overlaps with the cone axis of brake body 5 and the axle X of storage member 3 substantially.
