Description

Technical Field

[0001] The utility model belongs to the technical field of jacquard machine equipment, in particular to a knife lifting mechanism of the jacquard machine. Background Art

[0002] During the operation of the jacquard machine, the equipment drives the lifting knife to move up and down. While moving up and down, the lifting knife drives the textile to move through the pulley set. It can be seen that the lifting knife and the textile are in a constant relative motion relationship. Every time the lifting knife moves, friction and knocking will occur between the lifting knife and the hook, and the impact force it bears is relatively large.

[0003] At present, jacquard machines generally use steel or aluminum lifting knives. The steel lifting knives are heavy and have large inertia during operation, so the movement of the lifting knives is difficult to control. The aluminum lifting knives are not rigid enough due to the characteristics of the material, and the overall hardness is relatively soft. The surface is easily damaged during the high-speed operation of the jacquard machine and needs to be replaced. However, when the wear of the lifting knife only occurs in a few places, the lifting knife needs to be replaced as a whole, which is inefficient and uneconomical. Summary of the invention

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a knife lifting mechanism of a jacquard machine.

[0005] The above-mentioned technical problem of the utility model is mainly solved by the following technical scheme: a knife lifting mechanism of a jacquard machine comprises a knife lifting plate, the upper end of the knife lifting plate is provided with a mounting groove, and a plurality of bosses are equidistantly provided on the rear side surface of the knife lifting plate corresponding to the mounting groove, and a sliding hole is provided in the mounting groove corresponding to each of the bosses, and the sliding hole is arranged rearward relative to the middle position of the knife lifting plate, and a rubber shock-absorbing pad is arranged at the bottom of each sliding hole, and a lower support rod is arranged on the front end surface of the knife lifting plate between two adjacent bosses, a buffer plate is arranged in the mounting groove, and the buffer plate is lifted away from the mounting groove, and a sliding rod is arranged at the position corresponding to the lower end of the buffer plate and the sliding hole, and the buffer plate is connected through the sliding cooperation of the sliding rod and the sliding hole, and the lower end of the sliding rod is located on the corresponding rubber shock-absorbing pad, and an upper support rod is arranged at the position corresponding to the upper and lower support rods on the front end surfaces of most buffer plates, and the upper support rod and the lower support rod are connected with a tension spring.

[0006] Preferably, a gooseneck knife lifting edge is provided on the front side of the upper end of the buffer plate.

[0007] Preferably, a connecting hole is provided at both left and right ends of the knife lifting plate.

[0008] Preferably, a plurality of weight-reducing holes are symmetrically provided on the blade lifting plate.

[0009] The utility model has the beneficial effects of adding a buffer plate to the knife lifting plate, the buffer plate is slidably connected to the knife lifting plate, when the knife lifting plate moves upward to the top, the buffer plate will be lifted a certain distance under the pulling of the tension spring, and will also be buffered by the rubber shock-absorbing pad when falling, so that the buffer plate will produce flexible movement when reaching the top, thereby reducing the impact of the knife lifting on the textile fabric; a movable buffer plate is provided, and when the gooseneck knife lifting edge on the buffer plate is worn, it is only necessary to replace the buffer plate separately, thereby improving economy.
