Features Imported bag-making machines are basically based on single functions. If they encounter another variety, they can only be completed by equipment with another function. The domestic bag making machine combines the needs of the domestic market, fully considers the user's specific situation, adapts to the different needs of users, and designs and develops a multi-function bag making machine. Comparison of major functions The domestic machine can process three-side seal, middle seal, four-side seal and partial seal bag, as well as stand-up bag and zipper bag with concave and convex buckle. No need to change the body, it is very convenient to use. It is 3 to 4 times the working capacity of the imported machine. , Provincial site, electricity and investment. Comparison of small functions In terms of processing concave-convex zipper bags, the domestic machine has developed a set of positioning protection devices that do not require cooling water. Once commissioned, there are no scrapping problems in the production process unless there is a problem with the raw materials. Due to the diversification of the flexible packaging market, some users require back-sealing the pattern, and this function cannot be completed by the imported machine, which can only be trimmed by hand, which is labor-intensive and of poor quality. The domestic machine has newly developed a set of automatic sealing and cutting edge device for the middle seal, which not only guarantees the quality, but also works synchronously with the equipment, which is convenient to operate. Nowadays, more and more pearlescent films and milk powder bags are used in the market. The normal operation will inevitably produce crazing, and the same is true for imported machines, which will affect the beauty and quality of packaging. The anti-stringing device of the domestic machine makes up for this defect. According to the actual situation of users, combined with the domestic flexible packaging industry, mainly small and medium-sized enterprises, the width of some printing machines limits the size of bags. The domestic-made machine developed the upper and lower double-feeding device in consideration of the user's thinking, which brought the gospel to the small printing machine. The tasks that could only be completed with a 1.2-meter printing press in the past can now be completed with only a 0.6-meter printing press. The new generation of bag making machines considers that there are many female workers in the bag making workshop, and it is difficult to be competent for feeding. Therefore, an automatic feeding device is developed, which is combined with the unwinding part and is easy to operate, but the imported machine does not have this device. In order to reduce losses and facilitate operation, the domestic machine is also equipped with a shortage alarm device. Due to different quality requirements of users, different equipment, different raw materials selected, and different previous processes, the thickness of the film is uneven or the left and right are loose after compounding. According to the specific situation of domestic users, the new-generation domestic machine has been designed with fine-tuning devices in all parts from unwinding to traction, which can be fine-tuned on both sides and one side, making up for the deviation caused by the film and affecting the quality. The problem. The imported machine can't do this, it can only work normally when the raw materials are good and the previous process is qualified. Once the thickness is uneven and the elasticity is not equal, the bag from the imported machine will inevitably deviate. Because there is a large demand for milk powder bags and soy milk bags in the market, and it is required to seal and fold the edges before pressing the two sides. The new generation of domestic machines designed the second vertical seal according to market demand, which solved the market demand in time, which is also not available in imported machines. Judging from the comparison of the above functions, there are many defects in imported machines, which is also the pride and pride of a new generation of domestic machines. quality China is a world power in terms of machinery manufacturing, especially Shanghai. It has a long history of light industry machinery manufacturing and has a very solid industrial foundation. Shanghai ’s products enjoy a high reputation both domestically and in the world. In terms of steel and heat treatment, it has gradually become perfect. The machining accuracy of mechanical parts is no worse than that of imported machines, and some places surpass that of imported machines. The mechanical operation replaces the swing rod with a crankshaft to adapt to the noise generated during high-speed operation and increases the service life. The main parts have been tempered to make up for some of the deficiencies of domestic steel products, increasing the mechanical strength. The parts have been finely ground and surface treated to increase the accuracy and aesthetics of the size. The fuselage wallboards are all painted by surface heat leaching and then spray painted. Never allow scraping and sticking, so as not to take off the paint for a long time. price The price of imported machines is relatively high, 5 to 8 times that of domestic machines, but the large functions are only 1/4 of the domestic machines, the small functions are even worse, and the long-term maintenance and replacement of worn parts are not made in China. Convenient. In terms of years of return on equipment investment, imported machines are several times more than domestic ones. In other words, if the domestic machine recovers the investment in 2 years, the imported machine will take 10 to 16 years. According to the design concept of the imported equipment, many parts have reached the end of their scrap period when the investment machine has not yet recovered the investment period. If you continue to use it, you can only invest a lot of money to replace the configuration, so that the recovery of investment is far away. This comparison, this account, I believe everyone will count. Pre-sales and after-sales service There is no pre-sale service for imported machines. In order to be a good user's staff, domestic manufacturers suggest that users choose a reasonable model based on the user's specific production situation to maximize the benefit with the least investment. Domestic manufacturers attach great importance to the new concept of pre-sales service, and only innate perfection can provide less maintenance. Pre-sales services and after-sales services are like disease prevention and treatment. Only early prevention and more prevention can get sick later and less. After-sales service is a passive act, and only after perfect pre-sales service can we provide good after-sales service. In terms of after-sales service, replacement of consumable parts is much more convenient for domestic machines than imported ones. In terms of technology, domestic manufacturers not only manufacture conventional bag-making machines, but also customize various bag-making machines according to the needs of users, which are unmatched by imported machines. From this point of view, the gap between the domestic machine and the imported machine is gradually decreasing, and in some respects it has even exceeded the imported machine. Domestic machines will make greater contributions to the promotion of national industry.
