Description
Technical field:
The utility model relates to a kind of Rapier looms, especially relates to a kind of overhead cam opening device that is applied on the flexible rapier loom.Be widely used in the overhead flexible rapier loom of various fabrics.Belong to technical field of textile machine.
Background technology:
Cam opening device is installed on the flexible rapier loom, is used for strand limit heald frame and shedding heald frame that output speed is given loom.The cam opening device that is used for flexible rapier loom at present generally has two kinds of versions: active type cam opening device and passive type cam shedding motion.The former adopts case structure, can realize bath lubrication, but because the strand limit on its camshaft is all identical with cam set angular speed with shedding with cam set, therefore can only export a kind of cam rotating speed, and since the strand limit heald frame of flexible rapier loom and shedding heald frame together, strand limit heald frame needs the different input speed and the characteristics of motion with the shedding heald frame, and is difficult to realize this requirement with the cam contour of single angular speed, can only be applicable to single fabric of planting.Latter's passive type cam shedding motion adopts line paper to do signal output, and applicable to the requirement of various fabrics, but because its complex structure can not be realized bath lubrication again, difficulty further improves weaving speed, and the manufacturing cost height, and maintenance is complicated.In addition, weaving twill, when the satin fabric is put down and combined, require all strand limit heald frames and shedding heald frame at same horizontal level, and existing cam opening device all can't realized this function.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can the multiple cam rotating speed of output, simple in structure, can realize bath lubrication, and can make all strand limit heald frame and shedding heald frame overhead cam opening devices on the flexible rapier loom of same horizontal level.
The purpose of this utility model is achieved in that the overhead cam opening device on a kind of flexible rapier loom, comprise: casing, line shaft, power transmission shaft, camshaft, shedding arm axle and strand limit cam set, shedding cam set and shedding arm, described line shaft lateral means is on the wallboard of casing left side, power transmission shaft, camshaft and shedding arm axle vertically are installed between the forward and backward wallboard of casing side by side, and line shaft, power transmission shaft and camshaft are in transmission connection successively; Described strand limit is axially nestable on camshaft with cam set with cam set and shedding; Described shedding arm has multi-disc, axially nestable on the shedding arm axle, corresponding with each cam of cam set with the strand limit on the camshaft with cam set and shedding, each shedding arm lower end is provided with roller, the wheel rims of the corresponding cam with each of each roller is closed, and it is characterized in that: described strand limit is different with the angular speed of cam set on camshaft with shedding with cam set.
Overhead cam opening device on the utility model flexible rapier loom, described shedding arm axle is an eccentric shaft, is vertically arranged with blend stop on the box inside wallboard of shedding arm axle side.
Overhead cam opening device on the utility model flexible rapier loom, described shedding arm axle one end device has worm gear, worm gear and worm engaging, worm screw links to each other with handwheel or motor.
Overhead cam opening device on the utility model flexible rapier loom, described camshaft front end sleeve is equipped with strand limit bearing, the strand limit is equipped with strand limit gear and strand limit cam set before and after on the bearing, strand limit bearing cone and camshaft interference fit, outer ring and strand limit are twisted the limit and are connected with the cam set axial restraint with the strand limit with gear with gear and hinge limit cam set interference fit.
Characteristics of the present utility model have two: one, pass through line shaft, being in transmission connection of power transmission shaft and camshaft, between power transmission shaft and camshaft, two groups of travelling gears of realizing different speed ratios are arranged, make the strand limit that is contained on the camshaft cam set and shedding two groups of cams of cam set with differently contoured curve, realize different angular speed motions, thereby each shedding arm that drives on the shedding arm axle is done swing or static with rule separately, shedding arm top is connected to strand limit heald frame by steel cable and realizes the different movement velocity and the characteristics of motion with the shedding heald frame, and the answer of shedding arm is finished by return spring.Two of its characteristics are by handwheel or driven by motor worm and wormwheel eccentric shedding arm axle to be rotated, the eccentric axle center O of eccentric shedding arm axle is around center O ' do eccentric rotary, this moment, the shedding arm contacted with blend stop, the shedding arm on the right is under the motive force effect of blend stop, rotate counterclockwise, the shedding arm on the left side clockwise rotates under the effect of return spring power, thereby make the shedding arm at the effect lower swing of regulating blend stop, the angle of the crossing between the shedding arm is diminished, when the angle of the crossing is zero, can make strand limit heald frame and shedding heald frame on same plane, realize flat combining, be convenient to through axle and replacing cam kind.
In sum, the utlity model has following advantage:
1, can significantly reduce the manufacturing cost of the heald lifting device of Rapier looms.
2, can significantly improve the speed of service and the operating efficiency of Rapier looms.
3, do not change Rapier looms structure and existing dobbies and exchange, can on Rapier looms, realize moving and weave many kinds fabric in strand limit shedding and the warp thread shedding.
4, heald levelling motion electronic or manual drives is a heald levelling motion independently, is convenient to operation, and is convenient to change through axle peace combine.
5, can be used for weaving of plain weave on the flexible rapier loom, twill, satin weave.
6, stability of rotation do not have to impact, long service life, and noise is low, and is easy to maintenance, simple to operate, and it is few easily to lose part, realizes non-maintaining.
