Crank rocker type electronic jacquard machine

Abstract

The invention relates to a crank rocker type electronic jacquard machine and belongs to the technical field of textile machinery. The crank rocker type electronic jacquard machine comprises a machine frame, a power input mechanism and a heald lifting mechanism, wherein the power input mechanism is arranged on the machine frame and is in transmission connection with a main shaft of a loom in a use state; the heald lifting mechanism is also arranged on the machine frame. The crank rocker type electronic jacquard machine is characterized by further comprising a cam speed changing mechanism, wherein the cam speed changing mechanism corresponds to a position between the power input mechanism and the heald lifting mechanism and is in transmission connection with the power input mechanism and the heald lifting mechanism simultaneously. According to the crank rocker type electronic jacquard machine, the equipment investment is reduced; the grade of fabrics is improved, and the fabrics are embodied with an ideal economic added value; the whole-set cost of the crank rocker type electronic jacquard machine is controlled in a reasonable range, and routine check and maintenance are facilitated; the running effect of the jacquard machine is ensured.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a crank rocker type electronic jacquard machine. Background technique [0002] Because the electronic jacquard machine can weave fabrics with complex structures by matching with rapier looms, air-jet looms and water-jet looms, it is widely used in the textile industry. There are mainly two structural forms of the heald raising mechanism of the electronic jacquard machine in the prior art; one is a crank rocker structure; the other is a conjugate cam structure. Due to the limitation of the mechanical structure, the jacquard machine with crank-rocker structure is generally only suitable for low-speed weaving of narrow-width conventional fabrics, and narrow-width conventional fabrics do not have advantages in the market due to low added value of products. The jacquard machine with conjugate cam structure has the advantages of stable operation, clear opening, a...

Problems solved by technology

However, this approach is considered by the industry to be a desperate move, because on the one hand, abandoning the old and making new ones will cause a serious waste of original equipment resources, which is contrary to the energy-saving and energy-saving economic spirit advocated by the whole society. The manufacturers of electronic jacquard machines are often small and medium-sized enterprises with a wide range of large quantities and weak enterprises and even tend to retreat. It is unimaginable to replace crank rocker electronic jacquard machines with expensive conjugate cam electronic jacquard machines.
