Abstract
The utility model relates to an improved needle lifting driver of a two-needle bar warp-knitting machine, which overcomes the defects and insufficiencies of the needle lifting driver of the existing two-needle bar warp-knitting machine. The utility model is characterized in that more than two groups of crank-connecting rod mechanisms are arranged between a transmission chain of a needle connecting piece and a main drive shaft, wherein the fixing end of a crank of each group crank-connecting rod mechanism is hinged with a machine frame; the movable end is simultaneously hinged with the tail end of a connecting rod in a front crank-connecting rod mechanism and the head end of a connecting rod in a rear crank-connecting rod mechanism. In the needle lifting driver of the two-needle bar warp-knitting machine manufactured according to the utility model, the original line contact is improved into the surface contact to reduce the abrasion of moving parts so as to prolong the service life of equipment; the structural improvement obviously improves the running speed and precision of the needle lifting driver so that the productivity and the fabric quality can be improved. The utility model is a beneficial improvement actually.
Description
Technical field
The utility model relates to the transmission device of Weaving device, and particularly relevant a kind of improved double rib warp loom pin rises transmission device.
Background technology
It is that rigidly connected cam 10, rocking bar 11 and knitting needle connector 12 are formed (as shown in Figure 5) by one with final drive shaft mainly that the pin of traditional double rib warp loom rises transmission device, promptly is to be provided with a set of bell cranks---linkage from final drive shaft to knitting needle connecting rod driving-chain.Rocking bar can be done deflection for the center of circle with the rotation of cam according to the hinge 110 that is installed on frame, and the yaw motion of rocking bar drives knitting needle connector (connect pin and rise mechanism components) 12 and realizes and satisfy time---the displacement curve requirement of knitting needle pin liter.The maximum characteristics of this transmission device are that structure is simple and direct, and still, this structure is found to have following defective and deficiency through production practices: (1) roller is that line contacts with cam surface, so, because of its footprint pressure is big and easy to wear, influence the service life of equipment; (2) speed of related movement of roller and cam surface is limited, should not realize high-speed cruising, so, influence the raising of productivity ratio; (3) curve of roller and cam surface must be made conjugate curves, has brought certain difficulty therefore for the processing and manufacturing of related components, has increased the cost and the investment of equipment relatively.
The utility model content
The purpose of this utility model is to rise existing defective of transmission device and deficiency for overcoming and remedying the pin that has double rib warp loom now, rises transmission device and propose a kind of improved double rib warp loom pin.This device is realized by following technical scheme: a kind of improved double rib warp loom pin rises transmission device, comprise final drive shaft, cam, rocking bar, connecting rod, hinge and frame etc., it is characterized in that final drive shaft is to crank---the linkage that is provided with between the knitting needle connector more than two groups, each set of bell cranks---the crank fixed end in the linkage is articulated in frame, and the moved end then is hinged with preceding crank simultaneously---end of connecting rod and rear crank in the linkage---head end of connecting rod in the linkage; Final drive shaft is made a crankwheel admittedly, final drive shaft and crankwheel disalignment, and the head end of crankwheel and connecting rod is hinged, and crankwheel is coaxial hinged with the connecting rod head end, is that the axle hinge places in the same structural plan of connecting rod head end with the crankwheel; The knitting needle connector is the rocking bar that its stage casing is articulated in frame, and an end of rocking bar and preceding crank---connecting rod end is hinged in the linkage, the other end of rocking bar connect knitting needle pin ascending part spare.
Press the double rib warp loom pin that this programme implements and rises transmission device,, make the wearing and tearing minimizing of its moving parts and service life of having improved equipment first because of original line contact is improved to the face contact.Secondly, the improvement of structure has had more significantly raising because of the speed of service and the precision that pin rises transmission device, and helps the raising of productivity ratio and fabric quality.The utility model is real to be a kind of useful improvement.
