Description

 The invention relates to the field of textile industry, in particular to spinning production.

 A high-performance spinning machine for producing linen and cotton yarn is known, comprising a device for continuous fiber supply, an exhaust unit, a device for twisting yarn in the form of a turbine type spindle, a stacker and a take-up reel with a pinch roller (Lavrentieva E.P., Processing of cotton blends on cotton equipment, Textile industry, 1994, N 2, S. 16-19).

 In the known machine tool the necessary control and regulation of the yarn tension is not carried out, which reduces its quality.

 The objective of the invention is the creation of a high-performance spinning machine for linen and cotton yarn, ensuring the achievement of a technical result consisting in obtaining high-quality yarn by creating a constant tension of the yarn during spinning.

 This technical result in a high-performance spinning machine for linen and cotton yarn containing a device for continuous supply of fiber, an exhaust unit, a device for twisting yarn in the form of a turbine spindle, a stacker and a take-up reel with a pressure roller, is achieved by the fact that it contains a fixing ring to prevent the yarn from rolling in the transverse plane, a weight in the form of a ring placed on the yarn between the fixing ring and the stacker, and a position sensor mounted coaxially with Zeke and connected to the rotation rate control system receiving coil.

 The drawing shows a diagram of a high-performance spinning machine.

 The high-performance spinning machine contains a device 1 for continuous fiber supply, an exhaust unit 2, a device for twisting yarn made in the form of a turbine spindle 3, a retaining ring 4, a weight 5 made in the form of a ring, a position sensor 6, a stacker 7, a pickup coil 8 , a pinch roller 9 and a control system for the rotation speed of the receiving coil (not indicated in the drawing).

 The fiber device 1 for continuous supply of fiber is directed to the exhaust unit 2 and from the output of the exhaust rollers is passed through a spindle 3 of turbine type, operating from compressed air so that the vertical movement of the yarn from top to bottom is free, and the possibility of rolling the yarn in the transverse plane is excluded by the locking ring 4, made, for example, in the form of a cylinder filled with foam. The rotating impeller of the spindle 3 spins the fibers leaving the exhaust unit 2 into yarn. Then the yarn through the retaining ring 4 and the stacker 7 is fed to the take-up spool 8, rotating from the pressure roller 9.

 To create a constant tension of the yarn between the fixing ring 4 and the stacker 7, a weight 5 is suspended on the yarn, made in the form of a ring, providing free movement of the yarn.

 The position of the weight 5 in the vertical plane is controlled by a position sensor 6 connected to the speed control system of the receiving coil 8. When the weight is changed, the error signal from the position sensor 6 is fed to the speed control system of the receiving coil, which changes its rotation speed by changing the speed of rotation of the pressure coil roller, while the weight returns to its original position.

 The system is configured in such a way that the suspended weight 5 is constantly in a given area of permissible vertical movements. The speed of rotation of the turbine of the spindle 3 for twisting yarn is synchronized with the speed of exit of the fiber from the exhaust unit 2, providing the required number of fiber spins per unit length.

 The design of a high-performance spinning machine allows you to work at high yarn speeds of at least 50 m / min, which ensures high productivity of the machine.

 In addition, work with constant tension of the yarn dramatically reduces the likelihood of breakage and provides improved yarn quality.
