Product Background
Qinglong QLQZD-003 PLC micro-computer-controlled full automatic bearing marking line is a upgraded and substitutional product of QLQZD-002. The full auto bearing marking system is composed of the feeder with inverter, PLC micro-computer-controlled marking line and main computer-controlled collecting system. At present, most of bearing manufacturers use the manual marking on the product with plastic template marks. The characters made of plastic templates are not complete and sometimes discontinuous. Such the marks results in the reduction of the product grade. Marking Line QLQZD-003 features the exact positioning and marking time, legible and consistent marks, good stability and reliability, easy operation and high performance, liquid-saving and low template consumption, higher automotive level and domestic-advanced level. QLQZD-003 PLC Full Auto Marking Line will bring an innovation to the marking of your bearings. It will reduce the mark manufacture cost, improve the marking quality and efficiency, reduce the laboring intension and the number of operators, and ensure your enterprise to have more competitive powering the market with the brand marked.
The manual marking has many disadvantages. For examples, the material receiving, positioning, marking, feeding and fluid supply have to be completed by manual before a large number of marking work. It can not guarantee the ideal marking effect for a long period because of more operation time, inexact positioning, unstable pressure, unequal liquid supply , etc.. Additionally the material consumption is higher and the operators conditions in vigour and physical power, especially at night shift, will not keep the good marking quality.
Product Introduction
QLQZD-003 PLC Marking Line has an advantage of low manufacture cost. During the research and development period for many years, it has been modified and optimized many times in the whole system and it can be modified with lower cost on the preconditions of no influence on marking quality. It has the reasonable design, reliable performance and stable marking quality, easy operation and low laboring intension. Due to the integrated processing of the time in the individual loops by PLC, the marking speed and efficiency have been increased remarkably. The bearing feeding is completed automatically, i.e. the bearings are put into the feeder automatically, without manual interfere. The receiver has the reasonable design and it can deliver the bearing without any damage. The bearings can be lined in order for packaging or next procedure. The intelligent marking liquid supply is automatic to realize the liquid saving. The lower template consumption ensures a great reduction of marking cost on the precondition of a good marking quality.
Product Characteristics:
This product applies for the marking on the end face (flat face) of sphere bearing. It defers from the conventional marking. It can mark without any discontinuous lines and it can mark complicated brand patterns. It can mark on the sphere bearings from Φ40mm to Φ110mm even if the bearings path designs are very flexible. It is easy to change the templates and positions due to a tuning system provided for special templates. The system has higher automation level, including the auto bearing feeding, auto lining-up, auto marking, auto liquid supply, auto counting and auto receiving. It is also provided with the design such as the marking liquid (electrolytic liquid) lack alarm, bearing feeding lack alarm, template life counting, feeder auto stop with receiver full alarm.
1. Kinko CPU306 24-dot 16-bit PLC, highly integrated, less faults, high marking accuracy, marking time control by microsecond
2. Eview MT506T, 256 colors, 5.7STN touch screen for good display and easy operation
3. With a high-accuracy stabilizer;
4. With a main control board (only one circuit board) for rapid restart after fault elimination.
5. Over current protection for marking (alarm more than 16A) to minimize the faults of main control board for marking;
6. Over voltage protection for marking (alarm more than 15V) to prevent the template from burning due to over voltage;
7. Marking conduction testing technology. The marking has to start only after conduction, i.e. it would not start before conduction( Normally the marking time is counted from the moment of marking cylinder gonging down. However the used marking time is much less than the actual marking time);
8. Marking head humidity testing technology. Ensure the marking liquid to be supplied properly, without over supply or a lack.
