Tape slitter starts up
1. Change the specification, the paper core is on the inner and outer winding arms, and the pressure roller is in the ready state to notify all personnel to leave the machine and prepare to run.
2. Put the ANTI-STAIC BARS on the main console into AUTO, READY TO RUN is turned on, and start MACHINE RUN to start up.
Tape cutting machine cutting control
During the slitting operation process, carefully observe and observe the effect of cutting and cutting, and appropriately adjust and control the slitting speed, unwinding tension, contact pressure, curved roller, edge pulling roller and leading edge.
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).
Reasons, countermeasures and effects of BOPP film slitting quality ---
The raw edge product not only affects the appearance, but also directly affects the use. The edging product is observed with a magnifying glass. The edge of the film is jagged. The film roll is prone to breakage during use, and the consequences are very serious. For example, if the printed film breaks during the printing process, the ink will be caused. Splash, need to clean the machine and the ground, and then lead the film, re-coloring and other processes, production of physical and working loss; if the tape film breaks during the coating process, it is necessary to open the oven more than ten meters, re-introduction Membrane, turn off the oven, heat up and reproduce. These are things that users are very annoying and we must pay attention to.
In addition, we must pay attention to the protection of the end face during the moving process of the film roll, the film end face gap caused by the operation accident, and the gap has high concealment, the problem is difficult to find and flow to the user, the product will be Use has a greater impact.
