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 ---

eleven. Width deviation is too larg

Each user orders the film according to the shrinkage rate of the processed object and the film to accurately calculate the film width, try to get the lowest value to reduce the production cost. Therefore, the slit film width is too small, it is very easy to cause users. The processing width is not enough, and the film width is too large, which causes waste on the user's materials. In both cases, the user's complaint or even compensation may be caused. In actual operation, although the film width has a certain tolerance, the film width should be adjusted as much as possible on the standard width of the production construction sheet.
     Excessive deviation of film width is generally caused by human factors. Therefore, in the process of slitting, we need to detect the film width in the first time after conversion, transfer of specifications, transfer, equipment cleaning, equipment maintenance, adjustment of the tool holder, and replacement of the blade. The problem of preventing excessive deviation of the film width occurs.

Slitting machine operation guide ---

8.1 The cutting personnel shall record the production status in the “production record of the cutting machine” and other related records, insert the product into the “product tracking card”, and fill in the corresponding content in time according to the column and frequency requirements set in the record. The disk customers fill in the theoretical weight of each product for the weight of the product label of the Xiamen Cigarette Factory (see the attached table for the theoretical weight of each product), and the content is complete, clear, true and accurate.
8.2 Records should not be filled in with a pencil. The record holder should sign the quality record and indicate the time the record was filled.
8.3 The records listed in the record (except the remarks column) should be filled in. If the corresponding content is not found or there is no item, it can be recorded by slashing. The operator should write the full name and must not only write the last name.
8.4 Record changes caused by mistakes, etc. shall not exceed three pages per page. The records shall be clearly identifiable after the change. For all kinds of quality records that are validated and validated by the product and system, the change shall be stamped with a proofreading or marked change. people.
