Detailed Description
For a better understanding of the nature of the present invention, its further description is provided below with reference to the following detailed description and the accompanying drawings.
The utility model discloses a wrapping paper tension control device, the tension control who is particularly useful for the packing plant of strip cigarette wrapping paper, concrete embodiment structure is as shown in figure 1, including opening motor 1, tension sensor 2, lead paper roll 3, dancer roll 4, conveying motor 5, tension bar balance cylinder 6, tension bar 7 and PLC controller 12. The PLC 12 is in communication connection with the tension sensor 2 and the opening motor 1. A paper guide roller 3 and a tension rod 7 are sequentially arranged between the opening motor 1 and the conveying motor 5; the paper pressing roller 4 is arranged above the conveying motor 5, the opening motor 1 is used for unreeling a packing paper coil 8, and the conveying motor 5 is used for conveying the packing paper after being uncoiled. One end of the tension rod 7 is provided with a roller for conveying wrapping paper and a tension balance cylinder 6 for keeping a preset tension, and the other end of the tension rod is provided with a tension detection block 13. A tension rod support 9 is arranged between the rotary roller and the tension detection block 13, and the tension rod support 9 is rotatably connected with the tension rod 7. And a tension sensor 2 is arranged at a corresponding position of the tension detection block 13, and the tension sensor 2 is used for detecting the tension of the packaging paper.
The tension detection block 13 is cam-shaped. The opening motor 1 and the conveying motor 5 both adopt servo motors. The opening motor 1 is provided with a worm gear gearbox, the speed ratio is 1:20, and the maximum rotating speed is 150 rpm.
Preferably, the air pressure of the tension equalizing cylinder 6 is constantly controlled at 1.5 bar. The tension rod balance cylinder 6 is provided with a tension control electromagnetic valve 10. The tension control electromagnetic valve 10 is in communication connection with a PLC (programmable logic controller) 12 and is used for controlling the connection and disconnection of compressed air of a tension rod balance cylinder. After the tension balance cylinder 6 is connected with 1.5bar compressed air, the packing paper on the rotating roller of the tension rod 7 is stretched downwards, and the tension of the packing paper is kept constant under the combined action of the opening motor 1 and the conveying motor 5.
The PLC controller 12 is composed of Siemens S7-300PLC, a digital quantity input/output module, an analog quantity input/output module, a touch screen 11 and the like. Through the touch screen 11, system parameters can be set to monitor the control process.
The utility model discloses a theory of operation:
the unwinding direction of the coil stock is clockwise, and the rotating speed of the opening motor 1 is controlled by a tension system; the conveying motor 5 rotates anticlockwise, and the speed signal is from the production speed of the packaging equipment, so that the speed of the packaging paper conveying line is consistent with the production speed of the packaging machine. The opening motor 1 drives the coil stock to unreel under the control of the tension system, and the conveying motor 5 outputs the uncoiled film. When the tension is normal and the equipment is running, the electromagnetic valve 10 is opened, and compressed air is output to the tension balancing cylinder 6, so that the tension rod 7 keeps proper tension. When the tension of the wrapping paper is too small, the tension detection block 13 rises under the action of the self gravity of the tension balance cylinder 6; otherwise, when the tension is too large, the tension detecting block 13 is driven by the tension of the wrapping paper to rise.
The tension sensor 2 converts the position of the tension detection block 13 into an analog quantity signal of 4-20mA, and then the analog quantity signal is input into the PLC 12 to calculate the tension of the transparent paper in real time. The PLC 12 compares the actual feedback value of the tension with a preset value through the tension of the packing paper collected by the tension detection sensor 2 and the running pulse of the host machine, the obtained deviation value is used as a moment compensation value, and the PLC 12 adjusts the rotating speed and the moment of the opening motor 1 according to the moment compensation value, so that the tension is adjusted.
When the tension is the minimum preset value or the wrapping paper is broken, the tension detecting block 13 is at the highest position due to the self weight of the tension balancing cylinder 6, and the distance between the tension detecting block 13 and the tension sensor 2 is 0.5 mm. And when the tension value calculated by the PLC 12 is the minimum preset value, displaying alarm information on the touch screen 11.
When the tension of the wrapping paper is gradually increased due to the traction of the wrapping paper, the tension detecting block 13 is gradually lowered, and when the tension of the wrapping paper is at the maximum preset value, the tension detecting block 13 is at the lowest end, and the distance between the tension detecting block 13 and the tension sensor 2 is 5 mm. When the tension value calculated by the PLC 12 is the maximum preset value, the PLC 12 controls the opening motor 1 and the conveying motor 5 to stop, the tension control electromagnetic valve 10 is closed, compressed air sent into the tension balancing cylinder 6 is cut off, and alarm information is displayed on the touch screen 11, so that abnormal occurrences such as package paper breakage or conveying deviation caused by overlarge tension are prevented.
After the rotating speed information of the conveying motor 1 and the unreeling motor 5 is calculated through the PLC 12, the current diameter of the reel can be calculated. Can set up on the touch-sensitive screen 11 and trade a roll diameter, after the reel diameter is less than the roll diameter of setting for, but alarm information suggestion. When the diameter of the reel is less than 65mm, the PLC 12 controls the touch screen 11 to output an alarm signal to prompt an operator to change the reel.
