China has a huge packaging market. With the transformation of China's role in manufacturing factories in the world, China’s production of goods has rapidly increased and more production capacity has entered China. Take drinks as an example. As of 2004, there were 800 breweries in China and 2,000 beverage factories. China produces a large number of commodities each year that require packaging. In particular, commodities produced by China to meet the needs of the international market require international-level packaging. As a result, the Chinese packaging machinery market will grow rapidly.
Looking at the whole industry of packaging machinery, we found that the overall technical level of domestic packaging machinery is insufficient, can not keep up with the needs of society, and it can't manufacture leading equipment. In addition to the lack of sound development plans in the industry, the government lacks corresponding macro-control measures, resulting in the relatively backward development of domestic packaging machinery.
New packaging machinery is often an electromechanical device, making full use of the latest achievements in information products. Designers of some enterprises in our country are not familiar with electronic products and are afraid to or will not use them, which greatly limits the improvement of packaging machinery. For example, many foreign new-type packaging machines mostly use separate transmissions, which greatly shortens the drive chain of the entire machine, greatly simplifies the structure, and greatly increases the accuracy and speed of work. The key technology here is to use the synchronization technology of multi-motor drive. In fact, it is not difficult to master this technology, but some designers do not understand this trend of packaging machinery. Another - the key technology is a large number of servo drives, but the old designers will not design and use servos and their control systems.
Advanced packaging machinery uses a large number of new detection systems to ensure the stable and reliable operation of packaging machinery. With the increased penetration of automation companies to the industry and the development of information technology, more designers have accepted advanced automation technologies and have used advanced automation products to improve the performance of the equipment.
The overall level of China's packaging machinery lags behind the level of developed countries for many years. In addition to the improvement of domestic manufacturers' technological level, the localization of foreign manufacturers also greatly promotes the automation level of China's packaging machinery.
A plate rolling machine is a machine that will roll different kinds of metal sheet into a round or conical shape. It can be also called a [roll bending machine", [plate bending machine" or [rolling machine".
There are different kinds of technology to roll the metal plate:
Four-roller machines have a top roll, the pinching roll, and two side rolls.
The flat metal plate is placed in the machine on either side and "pre-bent" on the same side. The side rolls do the work of bending. The pinching roll holds the plate.
Three-roller machines (variable pitch aka variable geometry) have one pressing top roll and two pressing side rolls.
The three-roll variable pitch works by having all three rolls able to move and tilt. The top roll moves in the vertical plane and the side rolls move on the horizontal plane. When rolling, the top roll presses the metal plate between the two side rolls. The advantage of having the variable three roll is the ability to roll many thicknesses and diameters of cylinders.
For example; The side-rolls are what produce the mechanical advantage. With the side rolls all the way open, one has the maximum mechanical advantage. With the side rolls all the way in, you have the least mechanical advantage. So, a machine has the capability of rolling 2-inch-thick material with the maximum mechanical advantage, but a job is only 1/2 inch thick. Reduce the mechanical advantage and one has a machine that can roll from 1/2 to 2 inches thick.A plate rolling machine is a machine that will roll different kinds of metal sheet into a round or conical shape.
