Problems solved by technology
But now these two substructures often interfere with each other when they drive the working parts at the same time. The force and moment generated by the two transmission chains cannot be completely balanced or offset. If the two transmission chains are inconsistent, redundant motion will occur. Smooth roots, generating large dynamic forces and moments

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 , figure 2 As shown, a jacquard machine opening mechanism with double crank adjustable opening height includes a main transmission mechanism and an opening height control mechanism. The main transmission mechanism consists of a first crank 1, a first connecting rod 3, a pendulum 5 and a second The crank 2 is used to transmit motion and power. The opening height control mechanism is composed of the second crank 2, the pendulum 5, the second connecting rod 4 and the rocker 6. The first connecting rod 3 is Replaceable connecting rod, the first connecting rod 3 of different lengths corresponds to different output angles of the rocker 6; the pendulum block 5 is a triangle, each vertex of which is a hinge point, and the pendulum block 5 The first hinge point C is hinged to one end of the first crank 1 through the fir...

The invention discloses a dual-crank opening height adjustable shedding mechanism of a jacquard. The dual-crank opening height adjustable shedding mechanism comprises a first crank, a second crank, a first connecting rod, a second connecting rod, a triangular swing block and a rocker. A first hinge point of the swing block is hinged to one end of the first crank through the first connecting rod, and the other end of the first crank is hinged to a first shaft on a rack. A second hinge point of the swing block is hinged to one end of the second crank, and the other end of the second crank is hinged to a second shaft on the rack. A third hinge point of the swing block is hinged to one end of the rocker through the second connecting rod, and the other end of the rocker is hinge to a third shaft on the rack. The dual-crank opening height adjustable shedding mechanism is a double-freedom-degree mechanism, the size of an opening can be adjusted only by changing the length of one connecting rod, and the product adaptability of the shredding mechanism of the jacquard is improved. Two sub-mechanisms do not interfere with each other, force and torque generated by two transmission chains are balanced or offset as far as possible, redundant motion is prevented from being generated, and the problem that the work of the shredding mechanism of the jacquard is unstable is solved fundamentally.
Description
technical field [0001] The invention belongs to the field of air-jet looms, and relates to a jacquard shedding mechanism, in particular to a jacquard shedding mechanism with a double crank adjustable shedding height. Background technique [0002] The jacquard mechanism completes the alternate lifting and lowering of the upper and lower warp yarns and realizes reciprocating linear motion. In order to complete the specific movement of the loom opening, the basic size of each rod of the mechanism must meet the weaving process. Different fabrics require different opening heights. The double crank jacquard mechanism uses different The length of the connecting rod is adjusted to the interrelationship of the dimensions of other rods, so that the longer connecting rod completes the opening with a higher height, and the shorter connecting rod completes the opening with a lower height. [0003] The jacquard mechanism is divided into two mechanisms, the opening mechanism and the hedgin...
