Problems solved by technology
The structure of the existing jacquard machine's heald lifting box cannot meet the high-speed and heavy-duty jacquard machine. The pure rigid structure of the heald lifting box produces destructive vibration force during high-speed operation, which is one of the reasons for the poor start-up state of the jacquard machine.

Embodiment Construction
[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0030] see figure 1 , 3 , 4, 5 shown, a kind of jacquard machine with elastic structure heald lifting tool box, including heald lifting plate 1, pull rod 2, lifting knife support 3 and heald lifting knife 4, said heald lifting plate 1 is equipped with several One said pull rod 2, each said pull rod 2 is respectively connected with a said lifter support 3 through a bolt 5 and a bolt shaft 6, and the said heald lifter is fixed under the lifter support 3 by a lifter nut 7 4. Elastic connection joints are adopted between the pull rod 2 and the knife-lifting support 3; the joint surface of the knife-lifting support 3 and the heald lifting knife 4 is connected by a viscoelastic layer 14; the heald lifting knife 4. The upper part and the middle part of the outer surface on one side are covered with constrained damping layer 8 respectivel...

The invention provides a heald lifting cutter box used for a jacquard and with an elastic structure. The heald lifting cutter box comprises a heald lifting plate, pull rods, heald lifting cutter supports and heald lifting cutters. The heald lifting plate is provided with a plurality of the pull rods, each pull rod is connected with one heald lifting cutter support through bolts and bolt shafts, the lower portions of the heald lifting cutter supports are fixedly provided with the heald lifting cutters through heald lifting cutter nuts, elastic connection joints are arranged between the pull rods and the heald lifting cutter supports, the combination faces of the heald lifting cutter supports and the corresponding heald lifting cutters are connected through elastic adhesive layers, and the upper portion and the middle of the outer surface of one side of each heald lifting cutter are respectively wrapped with a constrained damping layer. According to the heald lifting cutter box, the linkage mode of the pull rods, the heald lifting cutters and the heald lifting cutter supports is changed from a rigid linkage mode into a flexible linkage mode, components can carry out relative micro rotation and movement, bending and twisting vibration produced by the components is absorbed by elastic components between components of the health lifting cutter box, friction of warps in heald eyes is reduced, the broken end rate of the warps is reduced, and the warp stop frequency of a weaving machine is reduced.
Description
technical field [0001] The invention relates to the technical field of jacquard machines, in particular to a heald lifting tool box for jacquard machines with an elastic structure. Background technique [0002] The speed of the loom is getting higher and higher, and the load of the jacquard machine is getting higher and higher. There are new manufacturers of electronic jacquard machines, most of which are small jacquard machines, with needles ranging from dozens to hundreds of needles. 8192 needles and 10240 needles, the force is dozens of times greater, the speed of the loom is increased from 100-200 rpm to 750-1000 rpm, the movement system is impacted, and other parts cannot avoid severe vibration. [0003] The heald lifting tool box is the working part of the heald lifting mechanism of the jacquard machine. The weak part of the heald system, the heald lifting knife is a thin and flat part, the thickness of the working surface of the heald lifting knife is about 8 mm, and...
