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.

Causes, countermeasures and effects on the quality of BOPP film slitting quality ---

(iv) Effect of film roll tightness on product quality

(5) Coping methods
1. Reasonable principle: Applicable is reasonable, which means that the cutting operator and the quality inspector are too loose according to the winding/
Too tightly influence the degree of influence on different products, adjust the cutting process reasonably, and reasonably grasp the tightness of the film roll to meet the requirements of the use of film products.
2. Ningsong Motight principle: objective when cutting equipment status, product specifications, film performance characteristics, etc.
When the influence of the condition causes the winding tightness to be in an inappropriate degree, the principle of tightness is generally used, because the problem of over-tightening often makes the film unusable, except for the special requirements.
3. The principle of primary and secondary: it means that in the process of slitting production, small groups should be followed to the interests of large collectives.
The principle of benefiting the interests of the company, avoiding the pursuit of high output and high distribution for the purpose of reducing the quality of cutting, all should be based on product quality, maintaining the German crown film brand as the responsibility, effectively completing various production and quality indicators Effectively serve the enterprise and users, and strive to be the best supplier of film.
4. System Management Principles: Refers to the use of systematic, scientific management methods, practical, theoretical, and empirical
The accumulated cutting control method is compiled, and according to the optimal combination of different types of products, width, winding length, season and other external variables and slitting tension, pressure and other internal variables, the document control management is performed to form an operation guidance document. Minimize the influence of subjective factors, reduce the impact caused by insufficient individual ability or excessive dependence on experience, and continuously supplement, optimize and improve the operation guidance documents to meet the needs of system management.

Reasons, countermeasures and effects of BOPP film slitting quality ---

ten. Color circle

The factors that cause the film to roll the color circle are:
(1) Contamination equipment is contaminated: due to the pollution of the dust in the cutting workshop, as well as the operation of the equipment in the slitting process and the friction between the membrane and the friction generated by the static electricity, the cutting equipment continuously accumulates more and more dust. When it accumulates to a certain extent and fails to clean in time, it will pollute the slit film roll to form a color circle. In addition, the aging and hardening of the roll skin (sand) debris will also cause the color circle of the film roll to appear.
(2) The environment of the cutting environment is polluted: during the cutting process, due to the influence of some accidental pollution sources, such as the dust on the ceiling of the cutting machine, the exhaust of the diesel forklift, etc., the air is spread to pollute the cutting products. And form a color circle.
In order to effectively reduce the impact of color circles on product quality, the following measures must be taken:
(1) Do 5S work regularly to maintain the sanitation of the workshop and the cleanliness of the machine; (2) It is forbidden to open the doors and windows without sand filter for a long time, and keep the good habit of closing the door;
(3) The contaminated film on the surface of the parent roll must be removed before the film can be cut, so as to avoid the dirt of the surface film from contaminating the cutting machine;
(4) The diesel forklift that requires black smoke is kept away from the surrounding of the workshop to prevent the tail gas pollution from being cut into the products.
