Dezhou Huarui Machinery Equipment Co., Ltd. is a professional manufacturer of woven bag packaging equipment, with an annual output of more than 10,000 woven bag processing equipment, and its products are sold to more than 20 countries and regions. At present, it has developed into a modern enterprise from the development of woven bag cutting machine products to the whole machine and parts manufacturing, quality control and after-sales service.
Fault phenomenon: print adhesion
Causes of failure: (1) Sticky bag and storage stack are too heavy to cause adhesion when printing stacking, or sticking after rewinding; (2) Because the printing speed is too fast, the pulling force is too large to make the rewinding too tight: (3) Bad printing, such as improper angle of the drying device or machine failure; (4) ink drying speed is too slow or dry performance: poor; (5) temperature is too high and cooling is not complete or the ink is not heat resistant; (6) ink Overly oozing through the back.
Solution:
When printing or storing the woven bag printing machine, the stacking of the printed products should not be too high, so as to avoid the stacking load being too heavy to cause adhesion. Adjust the printing speed, control the pulling force, and ensure the rewinding is normal.
Check the drying device and drying angle to ensure the drying speed of the printed product. Improve the drying characteristics of the ink, add the original ink to increase the viscosity or add a dilution solvent with a small molecular weight and a high volatilization, and if necessary, increase the special diluent produced by the ink factory (or 90% ethyl ester 10% mixed diluent of ethanol) The amount of addition ensures the drying performance of the ink.
Control the ambient temperature, reduce the temperature of the workshop or warehouse, open the window door to convect the air, etc., to avoid the temperature is too high, try to use the heat-resistant woven bag ink.
