Abstract

The utility model relates to a shaft raising device which realizes the structure that two pages of heddle frames and four rows of heddles can be installed on one heddle hook simultaneously by adopting a double hook structural form with an upper heddle hanging hook and a lower heddle hanging hook, so that a double parallel single tappet shedding mechanism with four pages eight rows of heddle frames can be adopted to replace a double tappet shedding mechanism. The utility model can reduce the difference of the warp yarn tension of the upper and the lower layers of a shed and decrease the friction in the heddle frame motion to make the opening clear, and the improvement is beneficial to the running of shuttles and increases the labour efficiency. By adopting the utility model on a home-made weaving machine with shuttles and improving other places on the weaving machine a little, fabrics with high densities can be weaved, such as down-proof cloth.

Description

Palm fibre making device for weaving machine

The utility model relates to the shaft raising motion technical field in the homemade fly-shuttle loom shedding mechanism.

When fly-shuttle looms such as utilizing existing homemade GA615 type, 1515 types is produced high density fabric, often need the shedding mechanism of loom is transformed, the technical approach that is adopted is: adopt two four page of eight row heald frame of shedding cam, when this shedding motion shortcoming is shed open full gate mouth between the top line between formed shed open distance excessive; Unfavorable shuttle flight increases the chance that fault produces; The warp thread tensile stress is big, and unbalance stress, and warp thread ruptures easily, has a strong impact on fabric quality, has reduced the work work efficiency.Or adopt two page of eight row heald frame of single shedding cam shedding mechanism, though this shedding motion can satisfy the requirement of high density fabric, but its heald frame manufacturing technique complexity, its intensity can not be satisfied the demand, and is stressed excessive, fragile, opening sharpness is poor, the easy adhesion friction fluffing of yarn, end breakage height, its fabric quality also are difficult for guaranteeing.

The purpose of this utility model is to provide a kind of can satisfy that homemade GA615 type fly-shuttle loom shedding mechanism uses, and can satisfy and produce the high density fabric needs, the shaft raising motion in the fly-shuttle loom shedding mechanism simple in structure.

The purpose of this utility model is achieved in that harness threading adjusting screw(rod) 4 upper ends connect harness threading belt 3, the lower end connects goes up shaft hook, the structure upper end of last shaft hook 5 is a screw rod, the lower end is two hook forms, can be on a shaft hook with two pages of heald frames of fashionable dress, four row healds, heald frame crossbeam 14 hangs on the shaft hook 5, heald frame crossbeam 14 links with heald frame two curb girders 7, heald bar hole 6 at 7 liang of end distance heald frames of heald frame two curb girders, two heald frame crossbeams 14 more nearby, heald frame two curb girder lower ends connect with heald frame lower end heald crossbeam 14, the structure of following shaft hook 8 is the last double hook hook forms that places an order, and place an order and be hooked in the double hook centre position, following shaft hook 8 upper ends and heald frame lower end heald frame crossbeam 14 link, place an order hook and the jack stick 9 of following shaft hook 8 lower ends link, jack stick 9 links by harness threading screw rod governor motion 10 and treading rod 13, and by lower-shaft 11, shedding cam 12 is formed the single shedding cam mechanism of the upper and lower opening motion that can control heald frame.

Shaft hook 5,8 is two hook forms up and down, and two hooks are back-to-back, by welding or screw rod is fixed together, two hooks not in one plane, its phase difference size clear shed open of formed minimum and deciding between the top line during according to the shed open full gate.

Fig. 2 is a structural representation of going up shaft hook

Fig. 3 is the structural representation of following shaft hook

With reference to accompanying drawing the utility model is elaborated.Harness threading well-pulley rumble 2 is contained on the harness threading axle 1 of harness threading arm, the every limit, harness threading belt 3 lower ends that is enclosed within on the well-pulley rumble 2 all links by screw rod and last harness threading screw rod governor motion 4,4 times client links of last harness threading screw rod governor motion heald frame hook 5 of hanging oneself, the upper end of last shaft hook 5 is a screw rod, match with last harness threading screw rod adjusting screw(rod) governor motion 11, regulate the tension force of harness threading belt by regulating the harness threading screw rod like this, the lower end is two hooks, promptly on same shaft hook, back-to-back be fixed with two hooks by welding or screw rod, two heald frame crossbeams 14 capable of hoisting on a shaft hook like this, promptly on a secondary shaft hook, can hang four pages of heald frames, eight row healds simultaneously, this structure has suitably been dwindled the distance between the heald frame of suspension hook both sides, thereby the difference of levels warp tension when having reduced the shed open opening, for guaranteeing clear between opening, arrangement according to the heald frame position, two suspension hooks are designed to up and down misconstruction, its size between the upper and lower during generally according to the shed open full gate between the top line the clear shed open of formed minimum calculate and decide.Heald frame crossbeam 14 links with heald frame third curb girder 7, and heald bar hole 6 is distributed in 7 liang of end distance heald frames of heald frame two curb girders crossbeam, 14 appropriate locations, and two pages of heald frames are housed on each shaft hook.Corresponding with last shaft hook 5 is shaft hook 8 down, and following shaft hook and last shaft hook structure are different, and single hook of following shaft hook bottom links to each other with jack stick 9, and jack stick 9 lower ends link by harness threading spiro rod regulating device 10.Following harness threading spiro rod regulating device 10 lower ends link by screw rod and treading rod 13, and whole treading rod is a linkage, have formed a single shedding cam controlling organization jointly with lower-shaft 11, shedding cam 12.The operating principle of this loom is: rotate the linkage action that shedding cam 12 drives treading rod 13, thereby drive harness threading spiro rod regulating device 10 down, following jack stick 9, following shaft hook 8, heald frame crossbeam 14 and heald frame two curb girders 7, last shaft hook 5, last harness threading screw rod governor motion 4, harness threading belt 3 grades are on harness threading well-pulley rumble 2, pump and rotate to an angle with heald frame, thereby finish whole harness motion, with design two back-to-back suspension hook structures are arranged because the utility model has adopted on the shaft hook, so only need just can to drive four page of eight row heald frame and pump simultaneously, adapted to the high density fabric demand with single shedding cam, replace traditional two shedding cams, promptly utilized two and single shedding cams to control the harness motion of whole harness threading mechanism.

Adopt the two and single cam shedding of four page of eight row heald frame of the utility model mechanism, the difference that can dwindle shed open levels warp tension reduces the friction in the integrated box movement, suitable high density fabric, make opening clear, help the operation of shuttle, improved the work operating efficiency.Through facts have proved, on homemade GA615 type, 1515 type fly-shuttle looms, adopt shaft raising motion of the present utility model, and fabric guide roll, the warp let-off umbrella gear teeth of loom such as are compared at the aspect change slightly, can weave the standard compliant high density fabric qualified products of quality fully, substitute shuttleless loom as the DOWN PROOF dry goods.
