To troubleshoot the tissue rewinding machine, we have two steps:
1. The photoelectric protection function of a full-open toilet paper production and processing equipment has failed. The machine can still work after emergency treatment, but because there is no protection detection, the operator is worried about personal safety, which results in low work efficiency.
2. Remove the circuit board and conduct a visual inspection. It is found that the substrate around the power bridge stack is discolored. It is determined that the bridge stack has burned out, and the bridge stack is powered up and tested, but there is no response. Measured with a multimeter, the newly replaced bridge stack has also been burned out, so it is judged that there is a short circuit part. Check the components one by one from the bridge stack. It was found that a three-terminal voltage regulator block (7805) was broken down. The components were bought and replaced. After power-on, the power indicator on the circuit board was on. The operator installed the circuit board on the machine and operated in accordance with normal procedures to check whether the photoelectric protection function works. Covering the light eye with his hand, the falling knife stopped immediately and tried several times, all of which were normal.
maintenance:
1. The transmission device of the toilet paper rewinding machine, such as the gear chain, needs to be filled with butter over a period of time.
2. The rewinding machine generally does not cause any problems. The consumable parts are nothing more than pinions. If a printing knife is added, it is easy to break. The wool roller will become thin after one and a half years of use. If the embossing pattern needs to be replaced in terms of the steel roller embossing device, the steel roller needs to be transported back to the original factory for modification. It will not cost much.
3. Pay attention to the voltage of the rewinding machine to be stable, otherwise it is easy to burn the motor; pay attention to hygiene, do not let foreign matter fall between the steel roller and the hair roller.
Brief introduction of the advantages of roll slitting and rewinding machine
The characteristic of the paper slitting and rewinding machine is the addition of a rewinding motor controlled by PLC programming. The rewinding motor is connected to the rewinding shaft through a magnetic powder clutch; the unwinding mechanism of the product is provided with left and right upper and lower movements connected by a central shaft. The bracket, the left and right lower brackets are connected with rolling guides, the central shaft is hinged by a driving flange with left and right shift cylinders fixedly connected to the lower bracket, the top tight cylinder connected to the upper left bracket is rollingly connected with the top cone through a loose shaft, and the upper right bracket is movable A brake shaft is connected, and a top cone and a brake assembly are fixedly connected to the two ends of the brake shaft, respectively, and a lead screw is also connected to the left and right upper brackets to cause axial displacement along the central axis. The advantage is that the magnetic powder clutch has a long service life, stable operation, a cutting speed of up to 700 m / min, a good cutting quality, and an easy and easy installation of the original roll.
The synchronous speed regulating device of the paper roll slitting and rewinding machine is used to maintain the tension balance of the large and small rolls in the paper roll slitting and rewinding machine, including the PLC, the large roll adjustment component and the small roll adjustment component. The large volume adjustment component and the small volume adjustment component are connected. When performing the adjustment, the large volume adjustment component and the small volume adjustment component are connected to obtain the torque and speed on the large volume motor and the small volume motor, respectively. The torque and speed of the closed loop adjust the speed and torque of the large- and small-roll motors in a closed loop, respectively, so as to maintain the tension balance of the large and small rolls in the paper slitting and rewinding machine. Compared with the prior art, the paper slitting and rewinding machine has the advantages of precise tension control and extended service life.
