Rewinding Machine safety operation guide - 

Fifth, the tool change operation:
1. The bottom knife replacement is handled by the mechanic.
2. The rewinding machine must be stopped when the upper round knife is replaced.
3. After removing the round blade, replace the new blade and fix it.
4. Install the round knife seat, adjust the angle, and lower the round knife to make it close to the bottom knife.
5, running, paper test knife, paper edge is not, smooth.
6. The tightness and depth of the blade and the bottom knife should be controlled properly, not too tight, otherwise the new knife
The film will roll the knife; it should not be too loose, otherwise it will jump the knife and the hair; not too deep, otherwise it will cause double trimming; too shallow will jump the knife.

Rewinding Machine operation safety regulations - 

Second, the operation steps:

4, traction paper head, start switch paper, the paper passing through the following parts: curved rod - towel press paper knife in front of punching knife - punching knife - curved rod - felt paper stick - winding wheel (the whole process It is necessary to use jog feed or slow speed. When entering the punching knife, it is strictly prohibited to twist the paper into one or more layers, and pay attention to safety);
5. Set the number of production sections according to product specifications;
6. Take a bundle of paper tubes into the paper tube push-up rack of the machine, spread the paper tube, take one into the middle of the two winding wheels, (and then press the embossing stick), and slowly rotate the machine. Rewinding (the ropes bundled with paper tubes should be placed in accordance with the regulations, and should not be randomly placed);

Rewinder mechanical structure and control process ---

 

I. Overview of the double-roller under the paper rewinding machine
The mechanical structure of the lower paper rewinding machine is shown in Figure 2-1. It can be seen from the mechanical structure diagram of the rewinding machine that the lower paper rewinding machine is fed into the paper web from below the rewinding machine. The paper web is wound around a support roll and then rolled up with a roll of paper. The paper is ejected from the unwinding roll, passed through the lower transfer roll, and then the web passes through the slitting mechanism at a fixed position, bypassing the front backup roll (press The second roller in the direction of the paper line or the back support roller is then wound on the take-up reel.
During the rewinding process, the paper web passes through the eject roller, and the tension force formed by the paper web pulls the paper roll toward the support roller, and the tension of the paper roll is stabilized by the action of the tension, and the rewinding machine can be made at a high speed roll. The quality of the paper roll can be guaranteed when taken. The lower thread rewinding machine can also control the pressure between the platen roller and the paper roll by changing the transmission torque difference of the two supporting rollers, so that the pressure of the finished paper roll can be controlled, and the quality of the paper roll can be Do a good job of control.
It can be seen from the figure that since the slitting mechanism of the lower threader rewinding machine is installed at a fixed position, this can avoid axial sway during the rewinding process, and also facilitates the control of the winding of the paper roll. The role of most of these rewinders in the Middle East is not very high, very close to the ground, the center of gravity, relatively low, due to the lower center of gravity, the rewinder can remain stable at high speeds, so this Types of rewinding machines are widely used, and most of the paper mills in China use the lower thread rewinding machine. Through many practices, this rewinding machine is also the best performance. And its speed can reach 2,500 meters per minute, the width is also long, can reach 10 meters, can handle the rewinding of different types of paper, from low basis to cardboard can be re-rolled. Of course, it also has its own shortcomings. The disadvantage is that because it is close to the ground, it is not easy for the operator to access the bottom of the machine. It is also difficult to guide the paper. Therefore, when the mechanical equipment is installed, a pit will be placed under the machine. In order to make the operator more accessible, the high-grade rewinding adopts the automatic threading structure, and there is no such problem.
