Rewinding Machine Structure - Pressure Mechanism
1, the platen roller
First, in the rewinder system, the platen roller has a significant impact on the tightness control of the paper roll. Among them, the pressure adjusting mechanism plays a role of keeping the pressure of the paper roll and the supporting roll nip constant, and the main purpose is to prevent the paper roll from slipping or being wound too tight at the beginning of the work.
The paper roll is slippery because the paper roll is too light and the take-up is too tight because the pressure is too high until the rewinding to the late stage. In the modern rewinder system, the platen roller is automatically controlled so that additional weight can be applied to the paper web. The force.
2. Hydraulic (air pressure) suspension mechanism
Under normal circumstances, the adjustable pressure actuators use hydraulic suspension scale mechanism. We install a potentiometer attached to the platen roller to display the diameter of the finished paper roll, which is sent through the potentiometer. The signal is passed to the pressure program control unit,
To calculate the pressure, so that the oil pressure in the scale can be changed, thus achieving the pressure control of the platen roller.

Rewinding Machine operation safety regulations - 

First, the preparation work before starting
1. Clean up the dust on the machine;
2. Check the circuit of the machine (whether the circuit is damaged), whether the rotating parts (bearings, gears, etc.) are loose, whether the conveying belt is intact, whether the protective device is intact, if there is an abnormality, it needs to be replaced or reported to the workshop supervisor in time;
3. Is the amount of lubricating oil (butter, oil) of the rotating parts of the machine appropriate? Is the amount of white mineral oil on the perforating knife appropriate? If not enough, add the right amount of oil;

Second, the operation steps:

7. When the layers of paper are completely flat and enter the rewinding, the waste coils are taken out to the normal production state. 8, check the production situation:
(1) Check whether the two ends of the base paper are symmetrical. For example, the auger can adjust the auger on the unloading frame to the ends of the paper. (2) Check whether the punched paper is clear, the punching is not clear or the missing teeth are checked. Whether the knife is broken or not
Whether the wire is loose, adjust the height of the bottom knife, and mass production after inspection;
(3) Check whether the paper feeding tension of the rewinding paper is consistent, keep the paper surface flat and no wrinkles, such as inconsistency
Then adjust the paper return belt hand wheel on the paper exit frame;
(4) Check whether the paper between the embossing stick and the winding area is flat and tight, if it meets the requirements, if it does not meet the requirements,
Then adjust the gearbox handwheel (when adjusting the gearbox handwheel, you can't stop the adjustment, you need to turn it on slowly); (5) Check whether the semi-finished paper roll is tight, the diameter and weight meet the product standard requirements, and the two ends are neat (straight
The deviation of the diameter shall not exceed ±1mm, and the weight deviation shall be within ±2);
(6) Whether the width of the glue seal of the paper ball meets the standard (package standard is 10mm-15mm), the penetration of glue
No more than 3 single-layer papers;
(7) Do not arbitrarily tamper with the inverter, programmed wiring and settings in the electric box; (8) Non-operator operators must not let the machine operate without the consent of the supervisor;

Third,. After the above steps are checked normally, Slowly speed up to normal operation.
