Novel cloth moving type fuzzing mechanism
Technical field
What the present invention relates to is cloth moving type fuzzing mechanism on a kind of terry cloth loom, belongs to field of textile machinery.
Background technology
Fluff mechanism is an important mechanism on the terry cloth loom, and two big class fluff mechanisms are arranged at present, and a class is the portable fluff mechanism of cloth cover, and another kind of is the reed moving type fuzzing mechanism.At present domestic terry cloth loom still is a fly-shuttle loom mostly, and its fluff mechanism is the reed dynamic formula.Towel rapier loom is soon at the early-stage, and production firm seldom.Shown in the structural group prejudice accompanying drawing 1 of existing cloth moving type fuzzing mechanism, its power drives belt wheel 27, gear 25,24 rotations by being with 26 inputs synchronously, rotates thereby drive loop-pile controlling cam 7.
When loop-pile controlling cam 7 peaks, loop-pile controlling cam 7 clockwise rotates, under the effect of spring 23, cam swing arm 8 clockwise rotates, batch swing arm 12 and clockwise rotate by connecting rod 9, transition fork 10, connecting rod 11 drives, cloth cover rolling off fell, wherein formed the high governor motion of hair by connecting rod 9, transition fork 10 at least; Simultaneously, cam swing arm 8 also drives back rest swing arm 3 and rotates counterclockwise by connecting rod 6, transition fork 5, connecting rod 4, makes through the past reach of face by the back rest 1, realizes moving of cloth cover, for a distance is got out of the way in fluffing; Loop-pile controlling cam 7 continues to clockwise rotate drive cam swing arm 8 and rotates counterclockwise, and batches swing arm 12 and rotates counterclockwise by connecting rod 9, transition fork 10, connecting rod 11 drives, and cloth cover is return fell; Simultaneously, swing arm 8 drives back rest swing arm 3 and clockwise rotates by connecting rod 6, transition fork 5, connecting rod 4, makes through face by the back rest 1 and moves backward; Under the effect of, ground warp Tension Difference and the parallel that interweaved, realize fluffing at hair.Batch swing arm 12 and drive 16 swings of face tension roller, the face tension between control work beam and the cloth beam by connecting rod 14, fork 15.When loom need be knitted plain cloth, electromagnet 21 held angle arm 24, hooked the pin on the cam swing arm 8, and roller M and loop-pile controlling cam 7 on the cam swing arm 8 are thrown off, and fluff mechanism is inoperative; By the more conversion of gear changing 24,25 realizations three latitudes fluffing and the fluffing of 4 latitudes.By regulating the variation of the link position realization terry height that C point, D point, E point, F order.The link position that change P point, N point, H are ordered makes the variation that is adapted to terry height through the amount of movement of face.It is to realize by regulating spring 20 that the warp tension of warp tension changes.But said mechanism exists mechanism's relative complex, and the heavy moving parts of entire mechanism is heavy, and rotator inertia is big, and power consumption is few, and the high governor motion of hair is unfavorable for effective adjusting that hair is high to the high adjusting weak effect of hair.
Summary of the invention
The object of the present invention is to provide a kind of improved, can realize that less regulating quantity and less point of adjustment realize that the bigger high adjustable range of hair, rotary inertia are little, power consumption is few, helps improving the novel cloth moving type fuzzing mechanism of the speed of a motor vehicle.
It comprises power input, rotate by synchronous pulley and gear driven loop-pile controlling cam, a cam swing arm that leans on mutually with loop-pile controlling cam under the effect of spring by a mao high governor motion O

The present invention is regulating Mao Gaohou, and cloth fell can not change, and parallel promotion connecting rod can change bar O simultaneously
1D and bar O
2The length of C, the amplification or the reduce in scale of increasing connecting rod mechanism movement amount realize the bigger high adjustable range of hair by less regulating quantity and less point of adjustment; Fluff mechanism is in parallel with tension adjustment spring sleeve type, has simplified mechanism, abdicates the space, can increase the fixedly back rest, when cloth cover was moved, the compensation rate of the back rest can be because of not changing through the axle size, and warp tension is more stable in axle change procedure from big to small; Entire mechanism heavy moving parts of the present invention is light, and rotary inertia is little, and power consumption is few, helps improving the speed of a motor vehicle.It has simple and reasonable for structure, and compactness is easy to use and reliable, can effectively regulate the high adjustable range of hair, improves the characteristics such as product quality of fluff mechanism.

The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing 2: shown in the accompanying drawing 2, power drives belt wheel 27, gear 24,25 rotations by being with 26 inputs synchronously, rotates thereby drive loop-pile controlling cam 7.
When loop-pile controlling cam 7 peaks, loop-pile controlling cam 7 clockwise rotates, and cam swing arm 8 clockwise rotates under the effect of spring 23.Rotate counterclockwise by connecting rod 9, transition fork 10, connecting rod 11, drive fluffing fork 12, cloth cover is moved apart fell, for certain distance is abdicated in fluffing.Cam swing arm 8 of the present invention, connecting rod 9 and transition fork 10 have been formed the high governor motion of hair, described cam swing arm 8 is also by connecting rod 9, transition fork 10, connecting rod 6, transition fork 5, connecting rod 4, drive activity back rest swing arm 2 rotates counterclockwise, and makes through face toward reach by the movable back rest 3.Loop-pile controlling cam 7 continues to clockwise rotate, and cam swing arm 8 rotates counterclockwise, and clockwise rotates by connecting rod 9, transition fork 10, connecting rod 11, drive fluffing fork 12, and cloth cover is shifted to fell; Cam swing arm 8 clockwise rotates by connecting rod 9, transition fork 10, connecting rod 8, transition fork 5, connecting rod 4 drive activity back rest swing arms 2, makes through face by the movable back rest 3 and moves backward; Under the effect of, ground warp Tension Difference and the parallel that interweaved, realize fluffing at hair.When loom need be knitted plain cloth, electromagnet 12 held angle arm 22, hooked the pin on the cam swing arm 8, and roller M and loop-pile controlling cam 7 on the cam swing arm 8 are thrown off, and fluff mechanism is inoperative.By the more conversion of gear changing 24,25 realizations three latitudes fluffing and the fluffing of 4 latitudes.Contact with roller M at loop-pile controlling cam 7 and to be in when the highest, adopt specific purpose tool, make bar O
