Glass Tempering Machine

The machine consists of loading table, heating section, quenching and cooling section, unloading table, and control system. It is used to manufacture flat tempered glass for furniture, home appliance, architecture glass, etc.

- Loading Table

The loading table is composed of rubber-covered rollers. When the glass is put onto the rollers, the glass will be conveyed automatically to the entrance of the furnace where it will be in ready-to-enter-furnace position and the rollers stop moving. It will send the glass into the furnace once the computer control system gives enter command.

- Heating Section

The structure of the heating section is of a double-layer box type covered with thermo-insulating material. Inside the section there is a conveyor system with high temperature resistant ceramic rollers, which are imported from well-known manufacturers. Heating elements are installed on the upper layer and lower layer of this section. The upper layer radiation plate is special heat resistant and anti-corrosion cast material. The heating element is of an integrated part with spiral type resistance erected on ceramic part, it's easy to replace. When the glass is going to enter the furnace, the front door of the heating section opens the rolls of the loading table and heating section move at the same time. When the glass is in the furnace, the front door will close and the glass on the rollers will be moved back and forth at the distance calculated by the controlling system automatically, so that the glass will be heated evenly. The upper section can be lifted up for maintenance. The heating elements are in matrix layout.

- Flat Quenching/Cooling Section

The alloy sections and steel sheet is cold riveted to avoid deformation of heat welding, ensure effectively the entire flatness at air face of quench. Rational nozzle aperture and arrangement of air hole guarantee the glass even cooling. The upper and lower quenches are combined with linkage and individual drives, which can actually control the rational height for air nozzle of quenches. Matched with balance control of upper and lower air amount, the top and bottom of the glasses can reach to optimum heat radiation, so as to ensure the flatness of tempering glass.

- Unloading Table

The unloading table is the similar as the loading table. When the glass is transported to the end of the conveyor, the rollers will stop, and the glass can be taken away by hand, or by robot, if there is available

- Control System

• Process parameters storage and recall, such as glass thickness, size, color, glass type and maybe different sources of float glass and etc. Whenever you produce a new order for different thickness, size, color, type, source and etc., you just enter the process parameters, and the system will memorize these process data. Next time, when you have the re-order, or the same order, you can re-call the data, and the machine will automatically use the stored processing data to produce.
• Controller for roller driving system.
• Controller for the temperature control.
• Controller for quenching control.
• The furnace has auto pre-heating function.
• After the shift of a day, the furnace will be in the stand-by status; only less than 25% of heating power will be consumed, while the ceramic rollers will be still running. And ahead of working time on the next morning, the system will start up to heat up to the working temperature until the operator begins the production.
• Main drive control system is accomplished by the inverter system, which is controlled by computer. Online of every part is controlled by computer.
• The main screen is the page displayed on the monitor during normal production. Thecontents displayed directly in English are the statuses of glass in the furnace, drivingsystem, temperature at each zone, time of heating, quench and cooling, set point of fansand length sum of pieces of glass in the furnace. This screen is for the operator's notice.
• The process parameter screen records when the pedal switch is actuated by the operator, temperature set point of upper and lower furnace, pressure set point of fans, quench time and cooling time set point. These screens are frequently used for normal operation. Maintenance screen is used by maintenance people to test every part of the system. System parameter screen is used by the manufacturer, in order to test the machine, it is not for any other people using, and otherwise the machine may be damaged. The system also has some supplementary screens, which will not be explained here.
