Problems solved by technology

[0002] The original one-time warping machine mainly uses a yarn guiding motor and magnetic powder brake or spring to control the warping sheet yarn tension. Its advantages are simple structure and low cost; its disadvantages are: first, the manufacturing accuracy is very poor, and the warping The speed is only about 15m / min, the diameter of the package is less than 600mm, and the efficiency is very low; the second is the low precision of tension control, the maximum tension is less than 1000N, and the tension of the inner ring and the outer ring is inconsistent; the third is the tension difference and fluctuation between single yarns Large, up to 10g or more

Embodiment Construction

[0016] Describe the present invention in detail below in conjunction with accompanying drawing:

[0017] The device includes the creel, screen reed, flat yarn roller, yarn drawing control device of the sub-crew, and the circuit and air circuit control device of the machine in the previous process. The circuit and air circuit control device of this machine described here are the automatic control devices commonly used at present. Yarn tension and warping speed. The creel is the part for storing the yarn bobbin and pulling out the yarn; the screen reed gathers the yarn drawn from the creel to a certain range according to a certain rule; the flat yarn roller uses two rollers to draw the yarn after the screen reed Clamp into pieces of yarn, and increase a certain tension; the split gallows moves up and down through the split reed, so that the yarn is divided into two pieces of yarn one by one at intervals, and put on split ropes for drawing in before weaving. The handpiece is th...

Abstract

The invention relates to a bi-motor yarn tension control device of a disposable warping machine, which is characterized in that a driving shaft (2) and a wrapping roller (6) are respectively driven by a motor; a three-roller delivery device is arranged above the front of the driving shaft (2), two ends of the wrapping roller (6) in the three rollers are respectively arranged in bearing blocks on a wallboard (29), and an upper pressing roller (7) and a side pressing roller (10) in the three rollers can be pressed or loosened on the periphery of the wrapping roller (6). The invention respectively controls the winding of the driving shaft and the yarn delivery of the three-roller delivery device through two motors because of controlling the yarn tension at a machine head, and the driving shaft controls the winding moment through the regulation of a transducer by utilizing the moment control principle so as to lead the driving shaft to realize the constant tension winding; and a three-roller drive motor realizes constant yarn winding speed through the regulation of the transducer by utilizing the speed control principle. The cooperation of the two control methods of the two motors accurately controls the yarn tension.

Description

Technical field: [0001] The invention relates to a warping machine, in particular to a dual-motor control piece yarn tension device of a disposable warping machine. Background technique: [0002] The original one-time warping machine mainly uses a yarn guiding motor and magnetic powder brake or spring to control the warping sheet yarn tension. Its advantages are simple structure and low cost; its disadvantages are: first, the manufacturing accuracy is very poor, and the warping The speed is only about 15m / min, the diameter of the package is less than 600mm, and the efficiency is very low; the second is the low precision of tension control, the maximum tension is less than 1000N, and the tension of the inner ring and the outer ring is inconsistent; the third is the tension difference and fluctuation between single yarns Big, reaching more than 10g. Contents of the invention [0003] The purpose of the present invention is to provide a warping sheet yarn tension control pre...
