[0002] Textiles, that is, products processed by textiles, include yarns, woven fabrics, knitted fabrics, braided fabrics, etc., which are divided into two categories: woven fabrics and knitted fabrics. China is one of the earliest countries in the world to produce textiles. The modern weaving production process controls the mechanical stroke of the machine and the tension, density and other parameters of the yarn through automated control and refined equipment. It can only be finally formed after multiple processing steps. Among them, the control of tension is particularly important. The tension control system is often a system integration of sensors and tension controllers. It is mainly used in metallurgy, papermaking, film, dyeing and finishing, weaving, plastics, wire and other equipment. It is an automatic control system that realizes constant tension or taper tension control. Its main function is to achieve synchronization between rollers and uniform control of winding and unwinding. The existing tension control device for textile processing manually increases or decreases the weight to make the lower connecting rod deflect outward, drive the upper connecting rod to press the textile outward, cooperate with each guide roller to make the textile tight, and realize the adjustment of textile tension. The traditional tension control device for textile processing requires manual intervention to adjust the tension, which is heavy in labor and cannot automatically detect the size of the textile tension, which is not convenient for textile production.

[0015] 1. When the tension of the textile is too small, the force of the textile pressing the detection roller also decreases, and the spring force decreases and begins to expand, which reduces the tightness of the press plate and the pressure sensor, and the pressure value of the pressure sensor decreases. The pressure sensor converts the excessively small pressure value into an electrical signal and transmits it to the single-chip microcomputer to complete the detection of the reduced tension. When the tension of the textile is too large, the force of the textile pressing the detection roller also increases, and the spring force increases, which increases the tightness of the press plate and the pressure sensor, and the pressure value of the pressure sensor increases. The pressure sensor converts the excessively large pressure value into an electrical signal and transmits it to the single-chip microcomputer to complete the detection of the increased tension.

As the lead screw rotates, the slider 1 will move downward. As the slider 1 moves downward, the inclined surface of the slider 1 continuously presses the inner end of the adjusting column, causing the adjusting column to slide outward, and the tension spring expands under force, driving the slider 2 and the adjusting roller to move outward, making the textile tighter. The textile presses the detection roller, causing the pressure value of the pressure sensor to increase until the pressure value of the pressure sensor reaches the appropriate size. The single-chip microcomputer The control motor stops running. At this time, the tension is appropriate, and the purpose of increasing the tension is achieved. When the pressure value is too large and the tension is too large and needs to be reduced, the single-chip microcomputer controls the motor to reverse, driving the screw to reverse, and the slider moves upward for a while. The inner end of the adjusting column is not subjected to force, and the tension spring contracts, driving the adjusting column, slider 2 and adjusting roller to move inward. The tensioning effect of the textile becomes smaller, the force on the detection roller becomes smaller, the spring expands, and the pressure value of the pressure sensor also decreases accordingly, until the pressure value of the pressure sensor reaches the appropriate size. The single-chip microcomputer controls the motor to stop running. At this time, the tension is appropriate, and the purpose of reducing the tension is achieved.

The detection mechanism 6 also includes a pressure sensor 67, and the pressure sensor 67 is arranged on the front side wall of the mounting frame 61.

They can independently detect the tension of the textiles and automatically adjust the tension of the textiles quickly and accurately.

[0028] The working principle of the tension control device for textile processing provided by the utility model is as follows: when the textile is processed and produced, the textile is first placed on the material roller 3, and then the textile passes through each roller in turn, first winding in from the guide roller 4 and winding out from the bottom, then winding in from the top of the rear adjusting roller 562 and winding out from the bottom, then winding in from the top of the front adjusting roller 562 and winding out from the bottom, then winding in from the top of the detection roller 66 and winding out from the bottom, and finally coming out from between the two discharge rollers 7, completing the winding work of the textile, and then connecting the textile to an external textile machine, the textile machine works to pull the textile to move, the textile is slowly tightened, and the detection roller 66 is continuously pressed to cause the detection roller 66 to be displaced, and the spring 6 4 is forced to contract until the spring 64 reaches the compression limit. At this time, the spring 64 continuously presses the pressure piece 65 due to its own elasticity, so that the pressure piece 65 and the pressure sensor 67 fit more closely. The single chip computer 8 controls the pressure sensor 67 to work, and the pressure sensor 67 converts the pressure value into an electrical signal and transmits it to the single chip computer 8. When the tension is too small and the tension needs to be increased, the pressure value of the pressure sensor 67 is too small, and the single chip computer 8 controls the motor 575 to rotate forward. The output shaft of the motor 575 drives the worm 574 to rotate. Because the worm 574 is meshed with the worm wheel 573, the worm wheel 573 will also rotate, driving the screw rod 571 to rotate forward. Because the pulleys 572 are both arranged on the upper end of the outer surface of the screw rod 571, the two pulleys 572 are connected. The two screw rods 571 are connected by belt drive, so the two screw rods 571 will rotate synchronously. Since the outer surface of the screw rod 571 on the same side is connected to the inner middle thread of the slider 1 52, the slider 1 52 will move downward as the screw rod 571 rotates. As the slider 1 52 moves downward, the inclined surface of the slider 1 52 continuously presses the inner end of the adjusting column 54, causing the adjusting column 54 to slide outward, and the tension spring 55 is expanded under force, driving the slider 2 563 and the adjusting roller 562 to move outward, making the textile tighter. The textile presses the detection roller 66, causing the pressure value of the pressure sensor 67 to increase until the pressure value of the pressure sensor 67 reaches an appropriate size. The single-chip microcomputer 8 controls the motor 575 to stop running. At this time, the tension is appropriate and the process is completed. For the purpose of increasing the tension, when the tension is too large and needs to be reduced, the single chip microcomputer 8 controls the motor 575 to reverse, driving the screw rod 571 to reverse, the slider 1 52 will move upward, the inner end of the adjusting column 54 is not subjected to force, the tension spring 55 contracts, driving the adjusting column 54, the slider 2 563 and the adjusting roller 562 to move inward, the tightening effect of the textile becomes smaller, the force on the detection roller 66 becomes smaller, the spring 64 expands, and the pressure value of the pressure sensor 67 also decreases accordingly, until the pressure value of the pressure sensor 67 reaches the appropriate size, the single chip microcomputer 8 controls the motor 575 to stop running, at this time the tension is appropriate, and the purpose of reducing the tension is achieved. It can autonomously detect the size of the tension of the textile, and automatically and accurately adjust the size of the tension of the textile.

[0029] It is worth noting that the single chip microcomputer 8S7-200 disclosed in the above embodiment, the motor 575 is a PCE530M4T motor, the pressure sensor 67 is an XJC-H80-D80-H30 pressure sensor, and the single chip microcomputer 8 controls the motor 575 and the pressure sensor 67 to work using methods commonly used in the prior art.
