Abstract

The utility model discloses a hackle cross woven opening mechanism which is a cross woven opening component of the window screen and is especially used for weaving the glass fiber window screen. In order to solve the problems that the transverse movement is off balance, and the rigidity of the heddle frame is poor in the existing hackle cross woven opening mechanism, the utility model uses the flat steel to make the transverse head, uses the angle steel as the transverse frame, and uses a fastener to connect with the assembly type heddle frame. A slide block type casting transition hitching leg and a fixed hitching leg are fixedly arranged between the heddle frame guide rail and the top beam, and thus the rigidity and the adjustability of the heddle frame and the entire opening mechanism can be enhanced. The cross traverse gear adopts a whole heddle frame traverse device which comprises an arc-shaped spring piece and manufacturing heddle iron; the structure of the cross traverse gear is simplified, and the stability is increased.

Description

Needle set-out cross weaving opening device

The invention belongs to a kind of strand and knit opening features, especially for weaving of glass window screening.

Existing glass window screening faller gill strand is knitted shedding mechanism (consulting " fiberglass weaving " book that building industry publishing house publishes), faller gill is done relative elevating movement about adopting two heald frames drives, and in elevating movement, by descending faller gill to carry out and traverse to reach the purpose that strand is knitted.Existing heald frame all adopts straight iron to be welded, so heald frame easily deforms under the effect of welding stress, processing and mounting hardness are big, and traversing of faller gill is to slide in the Baltimore groove of doup end heald frame down, fit tolerance is big, especially rolling bearing rolls in the groove of faller gill plate that traverses, and wearing and tearing are big, makes groove broadening in wear process.Therefore the motion generation that causes the plate that traverses is beated, and strand is knitted in the process, the end breakage height, and service life is short, and heald frame frame both sides guiding rail set structural stability is poor simultaneously, makes that also the quality of window screening is influenced.

At the problems referred to above, task of the present invention provides a kind of heald frame of assembly structure, and traversing gear is more easy, reliable, and the novel faller gill strand that fault rate is low is knitted shedding mechanism.

Knit shedding mechanism according to window screening faller gill strand provided by the present invention, there are two to do cross-peen by band steel, angle bar is done crossbearer, and the assembled heald frame that adopts screw or other securing member to interfix and constituted, in the hope of improving the rigidity of heald frame, avoid welding the stress deformation problem of being brought, on the heald frame lower cross frame, be connected with an adjustable act and combine device, in order to the lifting amount of adjusting heald frame as required.And traversing of faller gill is to head on rolling bearing on the heald frame that traverses by transversing slide lever, drives whole together the traversing of faller gill down and realizes.And resetting of the heald frame that traverses then finished by arc outside heddle-making irom in the head frame guides and the head frame guides or trapezoidal spring leaf.When descending, transversing slide lever traverses heald frame under the resilient force of spring leaf, reset by the heddle-making irom heald frame that promotes to traverse, the big I of the elastic force of spring leaf is regulated by the adjusting screw(rod) on the spring leaf, chute match casting system transition hanging feet and fixing hanging feet between head frame guides and back timber, have been adopted simultaneously, make heald frame can carry out as required with the perpendicular or parallel level in heald frame plane in adjust, make the stability of heald frame and adjustability be improved.

Described embodiment is described further below in conjunction with accompanying drawing:

Fig. 1, knit the shedding mechanism schematic diagram for faller gill strand;

Fig. 2, be heald frame traversing gear schematic diagram.

Shown in Fig. 1～2, its heald frame is the assembled frame structure, and make for angle bar the crossbearer of heald frame (36), (29).And the cross-peen of heald frame (30), (31) then be that band steel is made, crossbearer and cross-peen are linked into a rectangular frame by screw or other securing member, the cross-peen of heald frame is embedded in head frame guides (3), (4) in, and can move up and down along guide rail, and the heald frame that traverses (23) also can traverse in guide rail (38), on the lower cross frame of the last crossbearer of heald frame (24) and heald frame (23), fixed head is housed respectively, fixing last faller gill (13) and following faller gill (22), in heald frame (23), (24) two, lower cross frame bottom is fixed with two hinge pins (12) respectively and passes through to adjust adjustable opening connecting rod (10), (11), can regulate hinge pin arbitrarily to lifting the distance of combining arm, lift and combine arm (8), (9), the other end is fastened on the swing arm (7) by screw, two ends at swing arm (7) has two waist circular ports (16), lift and combine arm (8), (9) fixing after can in waist circular port (16), moving to the desired position, when swing arm (7) is the center with swinging axle (6), when making periodic wobble, heald frame (23), (24) also do periodic lifting, intert up and down, form open shedding.

In addition, exchange cam (18) is contained on the lower-shaft (28), traverse elevating lever (17) one end kinks on warp let-off axle (27), the other end links to each other with the connecting rod that traverses (15), because the effect of exchange cam (18), the elevating lever (15) that traverses is done oscilaltion, thereby the slide bar (14) that drives on the connecting rod that traverses moves up and down in slide rail (25).Side at slide bar (14) is provided with boss, when slide bar (14) when moving up, boss on the slide bar then heads on the supermedial rolling bearing of heald frame (23) (32), faller gill (22) moves right to force heald frame (23) to drive down, and have two holes in the top and the bottom of head frame guides (4), two heddle-making iroms (34) heddle-making irom, one end is housed in the hole is close to the high smooth surface in the outside (35) of heald frame cross-peen (31), the other end of heddle-making irom (24) abuts against on the arc-shaped spring piece (21) of being installed in head frame guides (4) outside.Heddle-making irom (34) is being pressed at the two ends of spring leaf (21), when slide bar moves down, heald frame (23) is under the elastic force effect of spring leaf (21), transmission by heddle-making irom, be pushed to again and move left, therefore the doup end of faller gill is every because of the moving up and down of slide bar (14) down, just traverses about the body warp both sides, thereby reached the purpose of strand, the big I of elastic force of spring leaf (21) is adjusted arbitrarily by adjusting screw(rod) (33).

In head frame guides (3), (4) the band chute fixed support (19) of a continuous casting is arranged respectively, and a slide block that matches with fixed support (19) arranged on the transition hanging feet (2), make transition hanging feet (2) in chute, in horizontal plane, to slide along the heald frame vertical direction, fixing with bolt (20) when moving to desired location, at transition hanging feet (2) and a chute that matches and a slide block fixedly also arranged between the hanging feet (1), transition hanging feet (2) can be in chute, the direction parallel along heald frame moves on horizontal plane, and be fixing with bolt (39) after moving to desired location.

The present invention adopts assembled heald frame and heald frame integral body to traverse, and arc-shaped spring piece resetting means, so that knitting shedding mechanism, the heald frame strand greatly simplifies, improve adjustability and the stability of shedding mechanism, simultaneously also so that the making of heald frame is greatly simplified, improved processing and installation accuracy, thereby the fault rate that the window screening strand is knitted reduces greatly, the window screening quality obviously rises, and owing to adopt the adjustable fixedly hanging feet of casting system, so that the stability of heald frame operation greatly takes a turn for the better. Therefore, because heald frame operates steadily, traverse accurately, so that the speed of a motor vehicle can be brought up to 140 rev/mins by original 120 rev/mins, enhance productivity more than 20%.
