Automatic Program Control Cutter Troubleshooting Example

Shandong Jinan Sanhuang Machinery Co., Ltd. specializes in various types of high-grade paper cutting machines such as automatic paper cutters, electric paper cutters, program-controlled paper cutters, and advanced machinery design and paper cutter manufacturing technology. Jinan Sanhuang Machinery Co., Ltd. uses a sqzk1300a. Program Control Cutter troubleshooting examples to introduce you to some of the issues need to pay attention to the use of automatic cutting machine, maintenance process. Program-controlled paper cutting machine is an auxiliary equipment used in printing production. Its advantages: easy to use, safe, efficient and good cutting quality. However, in the course of use, it is inevitable that some failure problems will occur, which will have some impact on production. Therefore, how to quickly and effectively troubleshoot problems and restore normal production of equipment is a concern for printing companies.

Failure performance: no over-initialized packaging, the display appears full 8 flash.

Sqzk1300a fully automatic program-controlled paper cutter in the boot process occurs after the pusher back to the limit, do not advance. No initialization, the screen appears full 8 flash words. According to circuit schematic analysis, the problem may lie in two aspects. One is the drive circuit and the other is the computer. First of all, the control circuit of the drive circuit is detected, the control is controlled, and the control element is tested normally. Check whether the five-core control cable of the encoder is normal and there is no problem with the test line. When the five-pin socket is inserted back to the original position, the normal eight-flash disappears. However, it didn't take long for the fault to repeat the full 8 flash. Pull out the five-pin plug again and the fault disappears. The analysis considers that there is a problem with the plug or socket. After careful handling, re-welding, or replacing the new plug. After processing, it was considered that there was no problem with variable data printing, but the machine did not take long to reappear again. Check the "11" core wire and socket are no problem, when the failure of good or bad impact on production. Once again, remove the computer board and check it carefully. Clean the circuit board with alcohol and find that there is a small crack in the connection of the five-pin socket. After the protective cover is cleaned up, it is turned on again with chrome iron welding and soldering, and the fault disappears completely. This kind of failure point is hard to find difficult to eliminate, so Jinan Sanhuang Machinery prompts you to repair such failures can not ignore the circuit board problems, prolonged use of deformation to break the lines, resulting in poor contact digital publishing, repeated failure phenomenon.
