Description

Technical Field

[0001] The utility model relates to the technical field of textile printing and dyeing equipment, in particular to a lead-out device in a circular textile machine for knitting grey cloth. Background Art

[0002] In ancient times, all the fibers used for textiles in various countries in the world were natural fibers, generally three types of short fibers (wool, linen, and cotton). In modern textile technology, in order to speed up the textile process, personnel set the introduction and extraction of fabrics into a fully automatic mode, namely the yarn drawing device, which is also one of the more important functional components in textile machines, especially air-jet textile machines.

[0003] For example, a Chinese patent discloses "a fabric pre-shrinking machine" (patent number: CN201610068857.6), which includes a machine body, a feed port, a discharge port, a heating roller, a pressure roller and a tightening roller. The above patent has a good effect, which is conducive to improving the pre-shrinking effect of the fabric, and then improving the product quality and performance.

[0004] However, in order to prevent the cloth from being torn due to excessive pulling force, the above patent sets a distance sensor on the cloth guiding device, and controls the rotation speed of the cloth guide wheel by detecting the positive and negative difference between the distance between the cloth and the distance sensor and the set value. However, the deformability of each cloth is different. Therefore, this simple measurement of the distance between the cloth and the sensor to determine the control speed is not accurate enough in judging whether the cloth is in the extreme deformation. Increasing the speed and accelerating the cloth delivery speed before the cloth even reaches the extreme deformation is also a waste of speed.

[0005] To this end, we propose a lead-out device in a circular textile machine for knitting grey cloth to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6 A lead-out device in a circular textile machine for knitting grey cloth comprises a base 1, wherein an arc groove 11 is symmetrically arranged on the base 1, and a first pulley 12 and a second pulley 13 are symmetrically rotatably mounted on the inner side of the arc groove 11, and an adjusting groove 16 is symmetrically arranged on the inner wall of the base 1 for adjusting the up and down movement of a mounting frame 22, and a mounting frame 22 is slidably connected to the inner side of the adjusting groove 16, and the mounting frame 22 is a U-shaped connection, and a pressure roller 23 is mounted on the inner side of the mounting frame 22, and the pressure roller 23 is moved when the cloth is led out. It is in contact with the cloth. When the cloth is subjected to force, it will be transmitted to the pressure sensor 21. The pressure detected by the pressure sensor 21 is then controlled by the control panel 14 to drive the pressure roller 23 to move downward to tighten the cloth, and move upward to relax the cloth to release the pressure. At the same time, the control panel 14 will control the traction motor to reduce the speed. The pressure roller 23 is provided with a first electrostatic layer 24. The first electrostatic layer 24 is arranged so that when the pressure roller 23 rotates on the surface of the cloth, the static electricity generated by the first electrostatic layer 24 can absorb the dust on the upper end surface of the cloth.

[0025] In detail, a first transverse plate 15 is welded to the inner side of the base 1, and the first transverse plate 15 is used for installing the first electric cylinder 2. The first electric cylinder 2 is installed on the first transverse plate 15 by bolts. The first electric cylinder 2 is controlled to extend and retract through the control panel 14 to drive the mounting frame 22 and the pressure roller 23 to move up and down along the adjustment groove 16. A pressure sensor 21 is fixed to the telescopic end of the first electric cylinder 2 by bolts. When the pressure roller 23 abuts against the fabric downward, the pressure sensor 21 can detect the pulling force on the fabric abutting against the pressure roller 23. When the pressure is too large, the pressure sensor 21 transmits an electrical signal to the control panel 14. The control panel 14 controls the first electric cylinder 2 to drive the mounting frame 22 and the pressure roller 23 to move upward to relax the fabric and release the pressure. At the same time, the control panel 14 will control the traction motor to reduce the speed. The pressure sensor 21 is fixed to the mounting frame 22 by bolts.

[0026] Furthermore, a control panel 14 is installed on the base 1, and the control panel 14 is electrically connected to the pressure sensor 21, the first electric cylinder 2, the second electric cylinder 18, the third electric cylinder 25 and the traction motor for pulling the cloth to rotate. The pressure sensor 21, the first electric cylinder 2, the second electric cylinder 18, the third electric cylinder 25 and the traction motor for pulling the cloth to rotate can be controlled by the control panel 14.

[0027] Furthermore, a guide roller 3 is rotatably connected to the inner side of the base 1, and the guide roller 3 serves as a cloth guide. A second electrostatic layer 31 is provided on the guide roller 3, and the second electrostatic layer 31 can absorb dust on the lower end surface of the cloth when the cloth contacts the guide roller 3.

[0028] In more detail, the third electric cylinder 25 is symmetrically installed on the mounting frame 22 by bolts, and the telescopic end of the third electric cylinder 25 is fixed with a connecting plate 26 by bolts, and the connecting plate 26 is located at the upper end of the pressure roller 23. When the first electrostatic layer 24 on the surface of the pressure roller 23 needs to be cleaned, the control panel 14 controls the third electric cylinder 25 to extend downward to abut the surface of the pressure roller 23 and contact the first electrostatic layer 24, and then the pressure roller 23 is rotated to clean the surface of the first electrostatic layer 24 through the wiping cotton 261.

[0029] In general, a second transverse plate 17 is welded to the inner side of the base 1, and a second electric cylinder 18 is symmetrically installed on the lower end surface of the second transverse plate 17 by bolts. A connecting plate 26 is fixed to the telescopic end of the second electric cylinder 18 by bolts. The connecting plate 26 is located at the lower end of the guide roller 3. The control panel 14 controls the second electric cylinder 18 to extend and drive the connecting plate 26 to move upward to abut against the second electrostatic layer 31 on the surface of the guide roller 3, and then the guide roller 3 is rotated. The surface of the second electrostatic layer 31 can be cleaned by wiping cotton 261.

[0030] Finally, the surface of the connecting plate 26 is bonded with the wiping cotton 261 via Velcro, and the connecting plate 26 and the wiping cotton 261 are bonded via Velcro, which facilitates the disassembly and cleaning of the wiping cotton 261.

[0031] Working method: put the cloth on the first pulley 12 and the second pulley 13, then pass one end of the cloth through the lower end of the pressure roller 23 and the upper end of the guide roller 3 to connect with the winding device of the traction motor. When the traction motor rotates, it will drive the cloth to be tightened and wound so that the cloth is close to the guide roller 3 and the pressure roller 23. When the cloth is subjected to force, it will be transmitted to the pressure sensor 21. The pressure detected by the pressure sensor 21 controls the extension and contraction of the first electric cylinder 2 according to the characteristics and deformation ability of the cloth. When it is detected that the pressure becomes smaller, the control panel 14 controls the first electric cylinder 2 to drive the pressure roller 23 to move downward along the adjustment groove 16 to tighten the cloth. When the pressure is too large, the pressure sensor 21 transmits an electrical signal to the control panel 14. The control panel 14 controls the first electric cylinder 2 to drive the mounting frame 22 and the pressure roller 23 to move upward along the adjustment groove 16 to relax the cloth and release the pressure. At the same time, the control panel 14 controls the traction motor to reduce the speed, so as to ensure the pre-shrinkage effect of the cloth.

[0032] At the same time, during the process of pulling the cloth, the upper end surface of the cloth will contact the first electrostatic layer 24 on the surface of the pressure roller 23, and the lower end surface of the cloth will contact the second electrostatic layer 31 of the guide roller 3. When the first electrostatic layer 24 and the second electrostatic layer 31 are in contact with the cloth, the cloth can be dusted by electrostatic adsorption.

[0033] When it is necessary to clean the surfaces of the first electrostatic layer 23 and the second electrostatic layer 31, the control panel 14 is used to control the second electric cylinder 18 and the third electric cylinder 25 to extend and drive the connecting plate 26 to abut against the first electrostatic layer 23 on the surface of the pressure roller 23 and the second electrostatic layer 31 on the surface of the guide roller 3. Then, the pressure roller 23 and the guide roller 3 are manually rotated to clean the surfaces of the first electrostatic layer 23 and the second electrostatic layer 3 with the wiping cotton 261.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
