The bearing seat 5 is provided with a turnabout drum 2 and fixed on a mobile device 6 through a bolt, a roller 6-3 of the mobile device 6 can move back and forth between an upper track and a lower track, one end of the mobile device 6 is fixedly connected with a hook connecting plate 7-1 through a bolt, one end of a tension buffer spring 7-2 is hung on a pull ring of the hook connecting plate 7-1, the other end of the tension buffer spring is connected with a tension sensor 7-3, the other end of the tension sensor 7-3 is fixed on a mobile seat 7-10 through a bolt, a nut 7-11 is welded on the mobile seat 7-10 close to the tension sensor 7-3, four nuts 7-11 are arranged at 90 degrees, a screw rod 7-4 penetrates through the mobile seat 7-10 and the nut 7-11 and is in threaded connection with the nut 7-11, when the screw rod, the screw cap 7-11 drives the moving seat 7-10 to move back and forth along the axial direction of the screw rod 7-4; the other end of the screw 7-4 penetrates through the support plate 10 to be supported by the support seat 7-6, the support seat 7-6 is welded on the support plate 10 close to the side of the forward and reverse rotation motor 7-9, the four support seats 7-6 are arranged at 90 degrees, the pinion 7-7 is welded on the screw 7-4, and the screw 7-4 can only rotate but cannot move along the axial direction of the screw through the support seats 7-6; the small gear 7-7 and the big gear 7-8 are ensured to be on the same plane and connected with an open gear, the big gear 7-8 is fixed on a transmission shaft of a forward and reverse rotating motor 7-9, and the forward and reverse rotating motor 7-9 is fixed on a fixed bracket 7-12; the tension transmitter 7-5 is fixed on the lower part of the support plate 10, the tension transmitter 7-5 is electrically connected with the tension sensor 7-3, and the positive and negative rotation motor 7-9, the tension transmitter 7-5, the deviation switch 9 and the PLC control system 8 are electrically connected.
The control process comprises the following steps:
when the positive and negative rotation motor 7-9 drives the big gear 7-8 to rotate, the big gear 7-8 can synchronously drive the four small gears 7-7, because the small gears 7-7 are welded with the screw 7-4, the four screws 7-4 can synchronously rotate, and because the front and the back of the small gears 7-7 are provided with the supporting seats 7-6, the screw 7-4 can only rotate in place and cannot move along the axial direction of the screw, the screw 7-4 is in threaded connection with the screw cap 7-11, the screw 7-4 rotates, the screw cap 7-11 is fixed by the moving seat 7-10 and cannot rotate, the screw cap 7-11 drives the moving seat 7-10 to move along the axial direction of the screw, the moving seat 7-10 drives the tension sensor 7-3, and the hook connecting plate 7-1 applies the moving displacement to the tension buffer spring 7-2, the tension buffer spring 7-2 is extended or shortened, so that the tension acting on the moving device 6, namely the tension acting on the adhesive tape 1 is changed (because the bend pulley 2, the bearing seat 5 and the moving device 6 are mechanically connected), and the tension sensor 7-3 acts on a tension loop, so that the tension generated in each tension loop can be detected in real time, and therefore, the tension in the tension loop can be changed when the forward and reverse rotating motor 7-9 rotates, and the tension can be detected in real time through the tension sensor 7-3, so that a closed-loop PID control can be formed; when the off tracking takes place for sticky tape 1 of sealing-tape machine, off tracking switch 9 can send light off tracking signal, and it is inconsistent to the tension that sticky tape 1 produced to show that two pulling force return circuits act on the sticky tape machine tensioning force, especially in short sealing-tape machine, sticky tape 1 can be to the off tracking of the little one side of tension, two pulling force return circuits pulling force size that can directly adjust driven roll 2, which side off tracking switch signals, which side pulling force return circuit pulling force increases, and opposite side pulling force return circuit pulling force reduces. The general adjustment method is as follows:
1. the light deviation signal of which side alarms, the tension of the tension loop of which side is increased, the tension of the other side is reduced, and the general step distance is 5 per mill (modifiable) of the rated tension value;
2. the signal of which side weight deviates alarms, the tension of which side tension loop increases, the other side decreases, and the general step distance is 10 per mill (modifiable) of the rated tension value;
3. the step pitch is the sum of absolute values of the adjustment values on the two sides, and the principle of increasing and decreasing is as follows: the pulling force value of the pulling force loop after the adjustment of the two sides deviates the rated value as little as possible;
4. for the calculated increased and decreased tension values as set values of PID control of corresponding tension loop tension, a tension transmitter detects actual tension as a feedback value to form closed-loop control of the tension loop;
5. the next readjustment interval time for the same deviation signal always exists is generally 3T (T is the time of one circle of running of the belt conveyor);
6. when no deviation alarm is carried out, the tension force is reduced, and the tension value of the tension loop is kept unchanged at the last set value by adjusting a positive and negative rotating motor of the tension loop.
The tension buffer spring 7-2 is arranged in the process of conducting the tension force, so that compared with the traditional thread tensioning hard connection, the effect of buffering is achieved by the tension buffer spring 7-2 when materials impact the adhesive tape machine, if the materials impact the adhesive tape machine, the impact force directly acts on the adhesive tape 1, and the adhesive tape 1 is easily damaged, and even the adhesive tape 1 is possibly broken; secondly, when the adhesive tape 1 is used for a period of time and is likely to be loosened (the adhesive tape 1 is slightly lengthened), the tension buffer spring 7-2 still plays a role in buffering, so that the tension force is slightly reduced, the PLC control system 8 is additionally arranged to adjust the forward and reverse rotating motor 7-9 of the tension loop according to the previous set value, the tension value of the tension loop is adjusted to the previous set value, unlike rigid connection, once the adhesive tape 1 is lengthened, the tension force is greatly reduced, and even disappears;
the invention really realizes on-line detection and automatic control, avoids the problem that the prior adhesive tape 1 is hard to find, does not need manual on-site treatment any more, and can further prevent the situation of overlarge or undersize tension force, thereby fundamentally preventing the phenomenon of losing and rotating or slipping of the adhesive tape machine.
