Description

Technical Field

[0001] The invention belongs to the field of wire guide adjustment for core yarns, in particular to a wire guide adjustment mechanism for core yarns. Background Art

[0002] Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The original core-spun yarn is a short fiber and short fiber core-spun yarn developed with cotton fiber as the sheath and polyester staple yarn as the core. Generally, synthetic fiber filaments with good strength and elasticity are used as the core yarn, and short fibers such as cotton, wool, and viscose are twisted together to form the outer covering. The core-spun yarn has the excellent properties of filament core yarn and outer covering short fibers. In the production and processing of core-spun yarn, a special core-spun yarn production device is required. In order to smoothly guide a variety of yarns to the spinning place in the device, the yarns are generally guided in an orderly manner through a wire guide device.

[0003] The existing wire guide adjustment mechanism for core yarn has the following main disadvantages:

[0004] 1. Troublesome adjustment: the existing guide wire adjustment mechanism for core-spun yarn core wire usually requires loosening the bolts to adjust the guide wire wheel, which is time-consuming and labor-intensive.

[0005] 2. The tightness of the core-spun yarn cannot be automatically adjusted. The existing guide wire adjustment mechanism for the core yarn of the core-spun yarn mostly adopts manual adjustment of the distance between the guide wire wheels. In many cases, when the core-spun yarn is loose, it cannot be discovered in the first time, causing problems in processing. Summary of the Invention

[0006] In order to make up for the shortcomings of the existing technology and solve the problems of being unable to recycle and being troublesome to adjust, the existing wire guide adjustment mechanism for the core yarn of the core yarn usually requires loosening the bolts to adjust the wire guide wheel, which is time-consuming and labor-intensive, and cannot automatically adjust the tightness of the core yarn. The existing wire guide adjustment mechanism for the core yarn of the core yarn mostly adopts manual adjustment of the distance between the wire guide wheels. In many cases, when the core yarn is loose, it cannot be discovered in the first time, causing problems in processing.

A bearing seat 1006 is provided on the side of the driving motor 1002 close to the active guide wheel 1001, and the bearing seat 1006 is fixedly connected to the first fixed plate 1003.

[0050] The specific workflow is as follows:

[0051] By pressing the button 1103, when the button 1103 is pressed, the second slider 1102 will drive the first connecting rod 1106 to swing. Since the first pin block 1107 is slidably connected to the first slider 1101, the swing of the first connecting rod 1106 will drive the first pin block 1107 to move, so that the first pin block 1107 is retracted into the first slider 1101. Since the first pin block 1107 is disengaged from the first positioning hole 1008, the first slider 1101 is in an unlocked state, so that the first slider 1101 can be in the first notch 1007. At the same time, the connecting rod 1110 drives the adjusting block 1203 to continue to move. Since the wedge block 1207 and the inclined surface of the adjusting block 1203 fit each other, when the adjusting block 1203 slides, the wedge block 120 7 will slide along the inclined surface of the adjustment block 1203 under the elastic force of the second spring 1205, so that the two wedge blocks 1207 are close to each other along the inclined surface of the adjustment block 1203, so that the second pin block 1204 is retracted from the second positioning hole 1208, so that the third slider 1201 is in the unlocked state, so that the third slider 1201 can slide in the slide rail 1211, so that the position of the slide rail 1211 can be adjusted, and then the button 1103 is released. The elastic force of the first spring 1108 causes the second slider 1102 to drive the button 1103 to reset, the second slider 1102 drives the connecting rod 1110 to move, and the connecting rod 1110 drives the adjustment block 1203 to reset, so that the first pin block 1107 and the second pin block 1204 extend. , and respectively engage with the first positioning hole 1008 and the second positioning hole 1208, thereby realizing the adjustment and fixation of the active guide wheel 1001. Two automatic adjustments can be performed through a button 1103, which greatly simplifies the operation and improves the efficiency of the staff in adjusting the guide wheel. The slide rail 1211 drives the first fixed plate 1003, the drive motor 1002 and the active guide wheel 1001 to move, adjust the active guide wheel 1001 to a suitable position, and then start the drive motor 1002. The drive motor 1002 drives the active guide wheel 1001 to rotate, and the active guide wheel 1001 rotates and moves the core-spun yarn. Since the second connecting rod 2003 is rotatably connected to the first fixed seat 2004 through the pin shaft 2008, and the pressure sensor 20 02 is located at the end of the pin 2008 away from the driven wheel 2001. When the driven wheel 2001 presses down the core-spun yarn, the end of the second connecting rod 2003 away from the driven wheel 2001 will swing upward and contact the pressure sensor 2002, so that the pressure sensor 2002 can detect the tightness of the core-spun yarn through the second connecting rod 2003. When the pressure sensor 2002 detects that the pressure is too low, the pressure sensor 2002 will start the electric telescopic rod 2006. The electric telescopic rod 2006 contracts and drives the second connecting rod 2003 to swing downward, so that the second connecting rod 2003 drives the driven wheel 2001 to press down the core-spun yarn. When the pressure sensor 2002 detects that the pressure reaches the normal preset value, it will automatically close the electric telescopic rod 2006.Thereby achieving automatic adjustment of the tightness of the core-spun yarn.
