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 ---

twelve. Interface quality problem (poor interface quality, interface identifier does not match)

3. Interface length and interface rate requirements
Since the interface products will inevitably generate certain scraps before and after the interface, and the quality of the interface products cannot reach 100% of the quality level of the interfaceless products, increasing the loss of use, therefore, the film manufacturers and users are The number of interfaces of the volume product and the interface ratio of each batch of products are specified, so that the interface products are controlled within a certain range.

4 operational requirements

4.2 Slitting

4.2.6 The customer is the product of Xiamen Cigarette Factory, and the length of the reel is cut. The weight of the reel label is filled in the theoretical weight of each product (see the attached table for the theoretical weight of each product). After the self-inspection is passed, the scale needs to be scaled one by one. The weight of the product is kept rounded to two digits after the decimal point. The weight of the product registered in the certificate and machine record table should be consistent, and the record should be true and accurate.
4.2.7 The products that have passed the self-test and the internal and external labels are neatly stacked on the tray. The number of products stacked on each tray and each tray is specified in the “Product Printing Process Card” and fixed with a cannula.
4.2.8 If the product does not meet the quality requirements, it needs to be removed or the product quality is in doubt. It is necessary to carry out re-inspection and strictly follow the “Rewinding Machine Operation Guide”.
4.2.9 Timely labeling and isolating materials, products, and materials to be processed at the production site, and taking the squad leader in charge of process identification and traceability operation control and integrated management according to the “identification and traceability control procedures”. After each shift is completed, the production report should be taken to the monitor.
4.2.10 If the product to be treated has not been processed within 2 working days, it should be reported to the workshop with the squad leader for timely disposal.
4.2.11 When the cutting machine is changed, it must be strictly in accordance with the “Regulations on the Management of Shop Closing”.
