Daily maintenance and maintenance of the slitter:
First, the electrical parts should be cleaned and inspected regularly to remove hidden dangers in time.
Second, the use of slitting machines is done by slitting machines and cross-cutting machines. Therefore, high-quality slitting cutters and cross-cutting cutters are used.
Third, the daily maintenance of the slitting machine should be in place. The standard is that smooth, clean, clear (no dust, no debris) is in place to ensure that the sliding part of the equipment is in good condition.
Fourth, it is the maintenance work, and the regular and irregular inspections of the rotating parts should be stopped (especially the real-time monitoring of the wearing parts should be stopped). Regular adjustments are made, regular changes are made, commutators are carefully recorded, and the purpose of extending the service life of the equipment is achieved.
Fifth, improve the technical quality and degree of the personnel who operate the slitting machine. The control of the local operation must be done by a special person, and no one can operate it without any permission.
Tension information detection method
(1) Tension sensor detection method: It is a method of detecting the tension directly, closely combined with the machine, and without moving parts. Usually two sensors are paired and mounted on the end shafts on both sides of the detection guide roller.
(2) Roll diameter calculation type detection method: It uses the proximity switch installed at the reel to detect the rotation speed of the reel. Because the reel rotates once, the winding diameter will change twice the thickness of the material.
The current diameter of the reel is obtained by cumulative calculation by the initial value of the reel diameter and the material thickness, and the change of the corresponding reel diameter reflects the change of the actual tension value.
(3) Floating roller position detection mode: It uses the cylinder attached to the slitter to connect the floating roller to drive the angular displacement sensor to detect the tension change. When the tension is stable, the tension on the material is balanced with the cylinder force, so that the floating roller is in the center position. When the tension changes, the balance between the tension and the cylinder force is broken, and the position of the floating roller will rise or fall. At this time, the swing lever will rotate around a point and drive the floating roller angular displacement sensor to rotate together.
(4) Floating roller position + tension sensor combined tension detection mode: It can simultaneously detect the floating roller position signal output by the floating roller angular displacement sensor and the tension signal output by the tension sensor, thereby providing higher precision tension control to the system. .
Slitting machine operating procedures -
Second, the volume of the replacement of the finished product (operating station)
8. Operate the button on the winding arm to wind up the paper core.
9. Manually cut the film to be cut onto the corresponding rewinding paper core. After tightening the film, it is firmly adhered to the paper core (note that the side 1 and side 2 films are differently worn).
10. After all the paper cores on both sides are glued, press “Crop 1 Clamp” and “Reel 2 Clamp” at the same time, and then press “Rewind side 1 open” and “winding side 2 open” at the same time. The position is automatically swung until the winding paper core is pressed against the upper roller, the winding main body is started, and the film is slowly wound until it is tight. (The two-button white indicator light turns from blinking to steady light)
11. Press the “MACHINE” button, the siren will sound and the signal light will flash yellow. Confirm that the personnel are in the safe area, press "machine on" again, the button light is always on, the machine starts and accelerates to the input set speed.
12. The main operator shall check the winding condition of each film and fine-tune the winding arm if necessary.
