Printing machine failure: on-site treatment of tooth pad wear

there is a second-hand MVO four-way four-color Heidelberg offset press, which has been used for many years. The tooth pad of the paper receiving tooth row is seriously worn, and its working surface has become very smooth, resulting in the paper not being clamped during the paper receiving process, affecting the normal operation of the paper receiving. If the whole tooth row is replaced, the cost is very expensive and the repair cycle is long

in this regard, we carry out on-site emergency treatment according to the actual situation. The specific method is: apply some iron filings on the working surface of the worn and smooth tooth pad, apply 502 glue, evenly stick the iron filings on the working surface of the tooth pad, and then trim the surface with diamond file after drying. This process is fast and simple, which makes the paper delivery return to normal, and meets the urgent need of mr.shay kastoriano, general manager of Yili engineering plastics production, and Wang Zhengqiang, deputy general manager of Toyota 1 Automobile Co., Ltd., who participated in the theme report.
