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.

Reasons, countermeasures and effects of BOPP film slitting quality ---
two. Wrinkles (wrinkles, vertical wrinkles, cross wrinkles, wrinkles)

With the continuous improvement of slitting technology, the length of wrinkle is becoming less and less, and the products of individual manufacturers have achieved zero wrinkle, which undoubtedly grasps the opportunities in the fierce competition environment. It is worth noting that the wrinkles that we sometimes appear are not caused by the unreasonable setting of the cutting parameters, but because our operators are not responsible for the work, and the film is not attached to the paper tube but is free. After the film is put on the paper tube, it is turned on and cut, and the quality of the wrinkle is artificially created. It must be paid attention to, eliminate the defects of human quality and improve the quality of the product.

Eight. Indentation
There are two reasons for the cause of film roll indentation. One is caused by the winding wheel of the film forming process, and the other is caused by the cutting factor. The reasons for the cutting are:
1 Due to the poor adjustment of the angle of the puller wheel, the pressure and tension of the puller wheel are concentrated on one point of the film, and the friction of the contact point causes damage to the film surface to form an indentation.
2 The winding roller is damaged, such as scratches, etc., the degree of film roll indentation is large when the scratch is longitudinal; 3 The winding roller is contaminated, causing the surface of the pressure roller to be uneven, such as adhesive tape, impurities, etc. It will also cause the film roll to be indented and the press roll must be cleaned.
Slight indentation does not affect the use of the product, but it affects the appearance of the product, causing the customer to doubt the quality of the product; the obvious indentation not only affects the appearance of the product, but also attenuates the corona value of the film, affecting the film.
