Warp Knitting Filament Warping Machine Tension Balance Device

Abstract

The invention relates to a tension balancing device of a warp knitting filament warping machine. The device is characterized in that: two motors are arranged in front of a straight reed (16) and in back of a hairiness detector (6) to drive a tension balancing device (5) for an upper tension roll (26) and a lower tension roll (24) respectively so as to control the tension of sheet yarns (7) wound into a pan head (13). The tension balancing device is arranged in front of the straight reed and in back of the hairiness detector, the upper and lower tension rolls in the device are driven by the motors respectively, the motors for driving the upper and lower tension rolls to rotate can realize different rotating speeds and different surface yarn speeds under the control of a computer respectively, and meanwhile, warps are positively pulled out by using the friction force between the warps and the surfaces of the two tension rolls to form a stable controllable tension area, so the tension of the sheet yarns wound into the pan head is dynamically controlled in real time, constant-tension and high-speed beaming is realized, the tension control precision is high, and the controlled tension range is large; and the device is convenient for automatic and intelligent control and has simple and practical structure.

Description

Technical field: [0001] The invention relates to a warping machine in textile machinery, in particular to a warp-knitted filament warping machine tension balance device. Background technique: [0002] The warp-knitted filament warping machine is the preparation equipment before the warp-knitting machine. The tension balance device is the key device for controlling the tension of the warping machine. During warping, the diameter of the package yarn changes from large to small , and its tension is constantly changing. And different varieties also have different tension requirements. In order to solve this problem, manufacturers such as German Karl Mayer Company, Taiwan Xinhong Company, Changzhou No. 8 Textile Machinery Factory and Changzhou Saijia Machinery Company usually use two methods to control and adjust the tension: one method is to use parallel tension up and down.

In order to solve this problem, manufacturers such as German Karl Mayer Company, Taiwan Xinhong Company, Changzhou No. 8 Textile Machinery Factory and Changzhou Saijia Machinery Company usually use two methods to control and adjust the tension: one method is to use parallel tension up and down. Two tension balance rollers are installed, the upper tension roller is fixed to rotate, and the position of the lower tension roller can be adjusted by swinging and then rotated after being fixed. The piece of yarn is wound in an "S" shape between the two tension balance rollers, and the tension of the piece of yarn is wound by the pan head. The wound yarn rubs against the surface of the roller and is dragged and rotated to generate tension. The tension does not change with the unwinding tension during operation. If you want to adjust the tension, you must adjust the fixed position of the lower tension roller to change the warp yarn on the second tension roller. The tension is adjusted by the size of the enveloping angle between them, the dynamic tension does not track, the yarn tension is uneven, and the operation is inconvenient; another method is that the upper tension roller is fixed and driven by a motor, and the lower tension roller is still the same as the above method. This method of tension adjustment is to change the rotation speed of the upper tension roller to actively feed the yarn, and second is to change the fixed position of the lower tension roller to change the enveloping angle of the piece of yarn and assist in increasing or decreasing the total tension. In this way, the tension control is still inaccurate. , The tension control adjustment range is small, the operation is inconvenient and other defects, resulting in inconsistent tension inside and outside of the same group of pan heads, inconsistent with each other, and a large error in the outer circumference, which directly affects the fabric quality and grade of the warp knitting machine, as well as the driving efficiency. Process requirements for weaving high-grade high-density ultra-thin and high-elastic fabrics
