(Summary description)According to the relationship between coating machine and paper machine, coating operation can be divided into internal type and external type. According to coating times, coating operation can be divided into single-layer coating and double-layer coating. In machine coating is a coating machine installed on the paper machine to stop paper making and coating continuously; out of machine coating is a coating machine which is independent of the paper machine and is used for coating operation. There are mainly three kinds of coating machines: roller coating machine, air knife coating machine and scraper coating machine.
Roller coater is used to apply coating to the paper surface by coating roller, and the coating inside the coater is mainly based on this kind of coater. The coating amount can be adjusted by the pressure between the metering rollers, the pressure will be increased, the coating amount will be reduced and the coating amount will be reduced.
The advantages of roller double-sided coater are simple structure, can stop double-sided coating at the same time, as an in-machine coater, it has more appropriate coating speed, and is not easy to produce coating streaks. The defect is that it is not easy to get the coating thickness of the air knife coater, nor the smoothness and gloss of the scraper coater.

Coating machine maintenance knowledge 2: conveyor belt maintenance

Coating machine maintenance knowledge 2: conveyor belt maintenance 1. Ensure that the coating equipment is installed horizontally, the grounding wire should be installed, and the independent leakage switch should be installed for safe use. 2. Keep the coater clean, use compressed air machine to clean the dust inside and outside the shell, thread debris and so on before starting up every day. 3. Hard objects (scissors, pens, rulers, tools, etc.) shall not be placed on the worktable and outer cover plate, so as not to be damaged by the conveyor belt. 4. Start the machine by pressing the power on first, set the temperature at 50 ~ 60 ℃ first, do not exceed 80 ℃ (realize the complete separation of upper and lower belts before speed regulating the conveyor belt) adjust the required temperature again. The speed, temperature and pressure can be adjusted freely according to the operation requirements. 5. Do not stop the machine suddenly when it is running at high temperature. In case of this emergency, use the manual device to rotate the conveyor belt slowly to prevent the conveyor belt from being damaged due to high temperature. 6. Clean the conveyor belt regularly (use the special detergent matching with the original factory to ensure the long service life of the conveyor belt): A. clean the conveyor belt once every 4 hours when the glue is sticking and permeating seriously; B. clean the conveyor belt once before shutdown. 7. Fill lubricating oil (high temperature grease) into the transmission parts and bearings of the coater regularly every day to ensure the long-term smooth operation of the coater. 8. If the coater moves to the original position after installation, be sure to adjust the level to prevent uneven pressure or belt deviation and damage. 9. When sticking and ironing, please try your best to make the upper piece smaller than the lower piece, and the width of the cloth piece shall not be greater than the width of the coater, otherwise it may affect the sticking and ironing, the conveyor belt deviation or the coater running and stopping. 10. After use, before shutdown, the pressure must be adjusted to no pressure state, turn off the heating system, maintain the conveyor belt, and then set the delay cooling or automatic shutdown.

Maintenance knowledge of coater

Coating machine need to do all aspects of maintenance work, not only can ensure that the equipment in the process of use, more safe, and reduce the occurrence of failure, also can better extend the service life, today's Ben Yue Xiao Bian to share with you coating machine maintenance knowledge: how to do daily maintenance work, some specific methods and what? If we want to do a good job in the daily maintenance of coater, we should: 1. Regularly check the different screws on the equipment to see if there is any looseness. Correct understanding of some specific circumstances and proper understanding of the corresponding requirements will guarantee the subsequent use, so we should really pay attention to this aspect. 2. Do a good job in basic cleaning, especially after stopping the use of the equipment, do a good job in all aspects of cleaning, so as to ensure that the equipment is not corroded, and also can guarantee the effect in the application process. Once the cleaning work is not done well, sometimes there will be greater errors, and the effect is difficult to guarantee. 3. The key parts should be lubricated frequently to avoid rust on the key parts due to temperature and other reasons, and the excessive friction of parts will affect the normal use of the equipment. The correct daily maintenance and maintenance of the coater, every once in a while to do some aspects of the inspection, to see some of the equipment, especially the screw loose problem. In the process of maintenance, we should also do a good job in cleaning. If we can do a good job in these aspects and make the whole cleaning work better, we will have more guarantee for our next application, so it is necessary to do these things in advance.

What are the technological requirements and advantages of the coater?

1、 Process requirements The coating machine needs to glue or ink materials uniformly adhered on the surface of aluminum foil, plastic film or cloth textiles, which requires higher coating process. It not only requires uniform coating height, but also can achieve high-speed non-stop roll change to improve production efficiency. 2、 Advantages of the scheme: 1. The tension control at all levels is completed by the frequency converter, and the tension control is realized by the tension sensor. The system is simple and stable. PLC or synchronous controller is used to control the speed of drive roller frequency converter, and it is also used as the linear speed signal of other frequency converters. 2. The dual position take-up and take-off reel has pre drive function, which can meet the requirements of high-speed automatic roll change without stopping machine and improve production efficiency. At the same time, accurate coiling control can avoid the bad coiling of vegetable heart type and make the coiling effect better.

Equipment and machinery maintenance

(1) Pay attention to regular maintenance, pay attention to production safety, operate in strict accordance with operating procedures. (2) The transmission parts should be filled with lubricating oil once every 8 hours, the bearing part should be replaced with lubricating grease once every 3 months after cleaning, and the motor bearing should be cleaned and replaced with lubricating grease once a year. (3) Fill the refrigerant regularly to keep the freezer working normally. (4) Frequently check the thermocouple fork hole, sensor and thermocouple glue handle for burning, if any, replace them in time, so as not to affect the accurate temperature value and mislead the work. (5) Often check the cutting edge wear or clearance condition, so as to avoid premature damage and affect the normal operation of the equipment. (6) Each shift should clean the metal conveyor belt and mesh belt to keep regular hygiene.
