At present, the common beating-up mechanisms in China mainly comprise a cam swing beating-up mechanism and a crank connecting rod swing beating-up mechanism, but the beating-up mechanisms have complex structure and low efficiency, and the beating-up mode is swing beating-up. The final beating-up cross section of the swinging beating-up mode is an inclined plane, which is very inconvenient when the three-dimensional multi-layer fabric is woven, and has negative influence on the mechanical property of the three-dimensional multi-layer fabric. Moreover, for high-density three-dimensional fabrics, the beating-up inertia of the beating-up mechanism is small, and the requirement of high density cannot be met.

But the device cannot achieve beating-up of high thickness fabrics.
CN 211497996 discloses a two-sided arranged beating-up and weft-insertion transmission mechanism, which comprises transmission units symmetrically arranged left and right, each transmission unit comprises a box body, and each box body is provided with a main motor output belt wheel, a beating-up gear, a beating-up cam shaft, a beating-up swing rod, a transmission intermediate wheel, a first beating-up gear, a second beating-up cam shaft, a second beating-up swing rod, a first beating-up swing arm, a rocker arm connecting rod, a second beating-up swing arm, a second beating-up gear, a second beating-up shaft, a speed-changing gear, a speed-changing pinion, a first bevel gear shaft, a second beating-up gear, a second beating-up pinion and a second bevel gear shaft. Although the whole structure is ingenious, the working efficiency is high, the automation degree is high, but the variable width beating-up cannot be realized, and the beating-up inertia is low, so that the method is not suitable for fabrics with high thickness.
Thus, while the conventional beating-up mechanism described above is employed for maturation on single layer textile looms, it is apparent that the conventional beating-up mechanism described above has failed to meet the needs of industrial production for new three-dimensional multi-layer textile looms.
