A double-needle bed warp knitting machine with horizontally reciprocating combs

Abstract

The invention discloses a double-needle bed warp knitting machine with combs horizontally reciprocating, which comprises a left wall panel, a pendulum shaft opening adjustment mechanism, dragon tendons, a machine head and a right wall panel. One end of the translational combing mechanism passes through the window of the wall panel and is supported by the sliding table supports on the left and right two ends of the wall panel. It is installed on the dragon tendon with the ground comb fixing seat, and the tension mechanism completes the opening and forming circle movement through the cam drive. It can realize the super-large opening of the double-needle bed warp knitting machine, realize the stable horizontal reciprocating movement of the wool comb, change the mechanical structure of the bar swing of the conventional warp knitting machine, and eliminate the scraping phenomenon of the bar swing. The take-off plate of the double-needle bed warp knitting machine can be freely adjusted from the small opening to the large opening, enriching the types of fabrics that can be knitted by the machine, improving the utilization rate and performance of a single machine, and realizing the super large opening inflatable cushion and Three-dimensional fabric weaving.

Description

technical field [0001] The invention relates to the field of warp knitting machine equipment, in particular to a warp knitting machine with double needle beds reciprocating horizontally. Background technique [0002] When the existing double-needle bed warp knitting machine knits fabrics, the wool bar swings in a circular arc on the front and rear needle beds to form a circle, which will cause friction between the wool bar and the formed base fabric coil structure, resulting in yarn scraping , in order to avoid yarn scraping and increase the swinging distance of wool, according to the traditional structure, only the swing arm can be increased, and the height of the swing arm is limited by the assembly and working conditions. The swing of the bar of the double-needle bed warp knitting machine is driven by the cam link in the headstock, and the bar swings around the swing shaft to realize the swing of the comb at the top of the swing shaft. The swing distance of the comb is de...

Problems solved by technology

[0002] When the existing double-needle bed warp knitting machine knits fabrics, the wool bar swings in a circular arc on the front and rear needle beds to form a circle, which will cause friction between the wool bar and the formed base fabric coil structure, resulting in yarn scraping , in order to avoid yarn scraping and increase the swinging distance of wool, according to the traditional structure, only the swing arm can be increased, and the height of the swing arm is limited by the assembly and working conditions

The swing of the bar of the double-needle bed warp knitting machine is driven by the cam link in the headstock, and the bar swings around the swing shaft to realize the swing of the comb at the top of the swing shaft. The swing distance of the comb is determined by the length of the swing arm. The height of the swing arm is limited by the structure, operating environment and strength. The trajectory of the swing around the axis is a circular arc. As the swing arm rises, although the curvature decreases, the increase in the radius makes the unnecessary height direction The increase of longitudinal displacement will squeeze the fabric, affecting the weaving effect and machine precision, so it is impossible to achieve super large opening

[0003] And the size of the opening limits the realization of double-layer three-dimensional fabrics, the structural pattern of the fabric is limited, and the style of the fabric and the weaving of the three-dimensional fabric are limited.

It is impossible to adjust from the small opening to the super large opening. For the small opening plush products, the super large opening inflatable cushion series products cannot be realized on the same machine, resulting in increased costs, poor compatibility of warp knitting machines, and affecting productivity. Therefore develop a kind of technical scheme that can solve the above-mentioned problem at the above-mentioned problem
