• Ask：Where is the advantage of a solvent free composite machine

  Answer： The solventless compound machine is compared with the solvent compound equipment. Solvent free composites have the following advantages：
  
  Fast compound speed
  

      The solvent free composite machine does not need to bake, has no residual solvent constraints, high production efficiency, the average composite speed of 250m/min, up to 600m/min, a composite function to meet the production of two printing machines.

  High degree of automation

      The solvent free compound machine adopts the proprietary equipment to automatically feed into the glue, automatically controls the proportion of the two components of the methyl and a B, automatically controls the temperature, and can adjust the coating quantity on line, the equipment is compact, and the manpower is saved.

  None of drying tunnel and low energy consumption

      The general charging capacity of the solvent type compound machine is 150-250KW, and the average energy consumption of one year is up to 50-70 yuan RMB, that is, the steam drying is used, and the energy consumption is not the decimal. The solvent free machine has lower power and no drying way. According to the information provided by Italy Nordmeccanica, the solvent free energy consumption is almost 1/20 of the solvent type.

• Ask：How to choose gravure press and solventless compound machine manufacturer

  Answer：     Gravure press、solventless composite machineand other composite soft packaging printing equipment manufacturers are numerous. The distribution of gravure press manufacturers all over the country has obvious regional characteristics. Zhejiang of the Yangtze River Delta (in which Wenzhou Ruian is the production base of Chinese gravure printing machine and dry compound machine), intaglio printing machine manufacturing enterprises, Shaanxi province and the Pearl River Delta of Guangdong are almost equal to the two, and then the Jiangsu intaglio printing machine manufacturing enterprises in the Yangtze River Delta also account for more share, Shanghai. In Beijing, there are also some manufacturers in Fujian, Yunnan, Shandong, Hubei and other provinces and cities, which are scattered as intaglio printing machines and dry compound machines. But in Shenzhen, there is a single show in the intaglio printing machine industry, and the technology is in the domestic gravure printing machine. Manufacturer: Shenzhen HappyField Packing Machinery Manufacturing Co., Ltd.
  

      In the face of so many intaglio printing machines, dry composite machines and other composite soft packaging printing equipment manufacturers, how do purchasers choose to have a regular model, strength, and can be reassuring and satisfactory manufacturing enterprises? Purchasers must locate their own printing needs, the demand of printing products and the possibility of future upgrading, and then examine the choice of the manufacturers of composite soft packaging printing equipment, such as intaglio printing machines and dry composite machines. Ruian is a well-known production base of Chinese printing machinery, plastic machinery, packaging equipment, pharmaceutical equipment and so on. It is a necessary station for the intaglio printing machine, dry compound machine and other purchasers.

      Shenzhen HappyField Packaging Machinery Manufacturing Co., Ltd. was established in 1995. It is a manufacturing service provider in China's printing equipment manufacturing industry. It is a high-tech private enterprise with rapid development, advanced technology and high equipment precision in the industry of intaglio equipment manufacturing in China.

• Ask：How to solve the problem of the daily malfunction of the gravure press

  Answer：Gravure press, dry composite machine, coating machine, solvent free composite machine and other professional manufacturers - Shenzhen Tianle Packaging Machinery Manufacturing Co., Ltd. is a regular model, strength type, high grade intaglio printing machine, composite machine, coating machine, slitting machine, bag machine and other series of soft packaging machinery and equipment specialized manufacturing enterprises, the quality of the products is excellent. Liang also exported to more than 30 countries and regions including Asia, Africa and Europe. The following are the daily troubleshooting methods for gravure press that I have listed. I hope it will help everyone in the routine maintenance and repair of the machine.
  1、The intaglio printing machine is always directed in one direction, to solve the problem: the main problem is longitudinal correction. It is possible to install or relock the plate without loading or loading. 
  2、Is the main motor unable to start? The main reasons are: 1. stop self lock and not open. 2. frequency converter start off switch line. The solution is: 1. loosening and stopping self lock. 2. connect the converter to start the switch line. 
  3. The main motor of the gravure press automatically stops and starts automatically. The main reason is the poor performance of the transducer. The solution is to replace the new VVVF potentiometer.
  4、Print transversal run? The main reasons are: 1. thin film printing performance is not good. The 2. guide roller is stained with ink. 3. the printing drying temperature is set too high. 4. the hot air is too large. 5. missetting of printing tension. 6. the machine is in trouble. The solutions are as follows: 1. select the specification film. 2. scrubbing guide roller. 3. set the appropriate printing drying temperature. 4. adjust the appropriate print air volume. 5. set the appropriate printing tension. 6. contact with our department, repair and debug. 
  5. The intaglio printing machine's color motor does not move? The main reasons are: 1. color motor power does not open. 2. color drive plate is damaged. 3. color socket connector is in bad contact. The solution is: 1. open the power of the color motor. 2. change the color drive board. 3. connect the socket connector line.  
  6. Unsteadiness of printing tension? The reasons are as follows: 1. the air shaft is not inflated, and the printing film is not locked. 2. the printing film itself has poor tension performance or too large eccentricity. The solutions are as follows: 1. the air inflated shaft is inflated to seal the film. 2. the film is fitted with a specification film. 
  7、The temperature control temperature of the gravure press can not reach the set low temperature. The reason is: 1. the solid state relay is damaged. 2. the temperature is lower than the ambient temperature. The solution is: 1. replace the solid state relay. The 2. setting is higher than the ambient temperature. 
  8. The temperature of the temperature control switch does not reach the high temperature of printing. The reasons are as follows: 1. the wrong operation settings exceed the ambient temperature. 2. temperature control switch gear setting is low. The 3. door is too big. The solutions are as follows: 1. set at ambient temperature of 30-40 degrees. 2. improve the temperature control switch gear. 3. adjust the appropriate air volume.
