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.
Slitting machine operating procedures -
Third, through the film：
13. 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)
Causes, countermeasures and effects on the quality of BOPP film slitting quality ---
(iv) Effect of film roll tightness on product quality
1. The winding is too tight:
1 fluttering/starting bone: As BOPP film, it is normal for the thickness of the product to fluctuate within a reasonable range. If the reeling tightness is appropriate, this thickness fluctuation will not affect the quality of use, but when the slitting is too tight The thicker layers of the film are stacked together to cause edge thickness or bone swelling, which affects the quality of use. The fluttering or bone formation that is formed by over-tightening is often difficult to find during the slitting process, but after the product has been stored for a period of time, the problem will be highlighted. In addition, there are several types of products with uneven thickness defects that can be easily revealed, such as ultra-transparent tape film, crystal film, heat sealing film, etc., while fluttering and bone-starting phenomenon will cause different quality of all film products. The degree of influence, especially for products that require printing and processing, is particularly prominent.
2 Adhesion: over-tightening of double-sided corona products, anti-corona products and products with less anti-adhesive content will cause adhesion quality problems, and the problem can only be found in the customer's use, the impact is great, and appears Products with adhesion problems can only be disposed of as scrapping, causing large losses to the company.
3 Face wrinkles: Due to the tight winding, the film cushioning performance is degraded. The wrinkles formed by the extrusion of the film on the end face of the product during handling and loading and unloading are difficult to eliminate, forming the end wrinkles and affecting the quality of the product.
4 Pitting: Due to the tightness of the winding, the film near the paper tube is affected by the rough surface of the paper tube, which causes pitting, which affects the quality of the product. The use of the polished paper tube will eliminate the surface of the film and improve it. Start wrinkles).
