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.

First, the program overview
The smart community is a new generation of products and technologies such as the Internet of Things, cloud computing, and information intelligence terminals. Through the automatic perception, timely transmission, timely release, and integration and sharing of information resources of residents' living information, the community is able to “eat and live†The digitization, networking, intelligence, interaction, and collaboration of the seven elements of life, travel, travel, purchase, entertainment, and health provide citizens with a safer, more convenient and comfortable living environment, making residents' lives more intelligent and Happiness and more harmony.
In the field of smart communities, Huasida is committed to becoming a new smart community solution partner, focusing on the community IoT communication network, community IBMS management platform and residential mobile phone APP operations, and innovating and developing a visualized intelligent community management platform, intelligent green bus, and wisdom The three core products of the community cloud platform and mobile phone APP, the polymer networking industry chain and the midstream and downstream partners, promote the sound development of the smart community ecosystem, and jointly provide customers with integrated solutions for the smart community.
The visualized intelligent community management platform is the core part of the smart community construction, and also the monitoring and commanding center for all intelligent systems in the entire community. It provides platform support for the basic data interaction services of the front-end intelligent system, and can be used for all intelligence in the community 2.5D electronic map. The visualization of the terminal is simple and efficient. When a fire alarm is issued in a certain area or when a security incident occurs in a certain area, video, lighting, and display screen linkage can be realized in the area to provide an emergency command plan for the community property management personnel and improve the community management personnel's response to emergencies. Processing capacity, truly unified monitoring, unified management, linkage alarm, and emergency command. The smart community integrated management platform includes, but is not limited to, the following basic modules: video surveillance, integrated security, lighting control, smart meter reading, background music, access control card, information release, electronic patrol, data dashboard display, and other modules. In order to realize the statistics, analysis and visual display of key data, the display data can be customized and displayed in real time, and various data concerned by the community managers can be displayed in real time (such as the number of current community households, the payment of current community property fees, and the energy consumption of the current month. The total number, the number of properties reported in the current month, etc., for the reference of community managers.
Huawei's world-first integrated intelligent hardware has integrated the terminal devices of the Internet of Things layer to establish an intelligent green bus and provided a network construction plan for the smart community. The intelligent green bus has outstanding advantages in construction, maintenance, management, and industrial applications. Compared with traditional intelligent construction, it has features such as easier installation and deployment, easier network maintenance, more uniform device management, and more efficient application management.
Huasida adheres to the “people-oriented†design concept and “fits up†the smart community cloud platform and mobile phone APP for the smart community, so that the community owners feel a safer, more convenient and comfortable living environment, making the community owners’ daily lives more intelligent and Happiness and more harmony. The owner's mobile phone APP includes, but is not limited to, the following basic functions: remote housekeeping, alarm notification, mobile phone opening, building intercom, property repair, property payment, and community O2O.
