(Summary description)Description of the structural advantages of the slitting machine

The paper tube slitting machine is equipped with a main shaft for processing paper tubes in the middle. The front end of the main shaft is fixed on the base with a set of bearings, and a pulley is installed in the middle of a set of bearings; a compression cylinder is installed near the base to support the cylinder. A set of support rod bearings is installed at the upper end of the rod to support the main shaft.

The main knife shaft is installed on the upper end of the paper tube slitting machine, and a number of blades are arranged on it, and arranged at a certain gap; the main knife shaft support frame is also set at the top of the paper tube slitting machine, and the support frame is at the top of the support frame. A supporting cylinder is installed in the middle. When there is a film on the slitting machine and the roll joint is changed, the vacuum film splicing table is used to first start the film splicing table to the working position, and the film on the first traction roller of the slitting machine is manually flattened and the upper vacuum pump is activated to suck the film. Adsorb it smoothly on the film splicing table, paste the double-sided tape and cut off the excess film under the tape, flatten the film on the unwinding rack and start the lower vacuum pump to make the film absorb smoothly, remove the upper paper layer of the tape and level it The mucous membranes and joints should be neat and wrinkle-free, then turn off the upper and lower vacuum pumps, and open the membrane splicing table to the non-working position.

Description of the control principle of the slitting machine

The essence of constant tension control in the process of unwinding and unwinding is to know the change of the coil diameter during the load operation. Due to the change of the coil diameter, in order to maintain the operation of the load, the split machine requires the output torque of the motor to follow the change of the coil diameter. And change. For the V series inverter, because it can do torque control, it can complete the winding constant tension control. The V series inverter provides three analog input ports, AUI, AVI, and ACI. These three analog inputs can be defined as multiple functions. Therefore, one can be selected as the torque reference, and the other one can be used as the speed limit. 0~10v corresponds to the inverter output 0~ rated torque of the motor, so that the constant tension control can be completed by adjusting the voltage of 0~10v. For Duyu slitting machine, the part that calculates the roll diameter is calculated by the tension controller. Of course, there is no problem to realize it with PLC architecture. In other words, you can set the tension on the man-machine or text, calculate the roll diameter through the PLC, T=F*D/2, so you can calculate the torque that the motor needs to output, and connect it to the V series frequency converter through the analog output The torque setting end of the converter is sufficient. Synchronous speed calculation of slitting machine manufacturers. Since we know that when the frequency converter is working at low frequency, the AC asynchronous motor of the slitting machine has poor characteristics, low activation torque and linearity, so it is necessary to avoid winding during the entire process of winding. The motor works below 2HZ. Therefore, the winding motor has a minimum speed limit.
