1. Description of main components of equipment
   1. Loading and unloading tables

The loading and unloading tables are similar in structure and are composed of customized steel frames. it is equipped with a cylinder transmission mechanism lifting table, which can lift synchronously and stably, and is equipped with the universal wheel. The roller is composed of a rubber roller and a rope roller. The high-quality coating is used to ensure that the glass surface is not scratched. In terms of transmission control, the stepping time is adjustable, the conveying speed is adjustable, the furnace feeding interval is controllable, and the sensitive glass detection device is equipped.

The loading and unloading tables are made of rubber-covered and Kevlar-rope 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 the ready-to-enter position, and the rollers will then stop moving. It will send the glass into the furnace once the computer control system gives enter command. The unloading table is similar to 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 it is available at the customer's factory.
 

 

   

 

 

1. 1. Heating system

The structure of the heating section is of a double-layer box type covered with thermo-insulating material. Inside this 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, and the "Exposed Matrix Heating Design" is adopted. Compared with the traditional "radiant plate heating design", this matrix system can improve the

 

 

1. 1. Passing section

The Passing technique is used to produce a glass thickness of less than [6]mm. Combined with Southtech's original electric energy control technology, it can flexibly allocate the electric energy of the heating system and quenching system in the process of toughening thin glass. In the production of thick glass, there is no need to turn on the passing section blower. The passing section can reduce energy consumption. It's no need to open the bigger blower after the passing section. It can almost save 60% of the energy of the quenching.
6mm, temperature conformity and heating efficiency in the furnace, and the heating elements are easy to replace. [The inside of the upper layer of the heating section is covered with 310S stainless steel with strong corrosion resistance.] The insulation layer is made of a high-quality aluminum silicate plate. After scientific sorting and six side polishing, it has better heat storage capacity, and can greatly improve the heat utilization efficiency. The heating section can open and close, and the upper heating section can be raised by the electric screw lifting device.

 

In the production process, before the glass enters the heating section, the front door of the heating section opens, the rollers of the loading table and the ceramic rollers of the heating section rotate at the same time, and the glass will be conveyed into the heating section. When the glass completely enters the furnace, the front door will close automatically, and the glass will oscillate back and forth at a distance calculated automatically by the control system to ensure that the glass can be heated evenly. After heating, the back door will open and the ceramic rollers will convey the glass to the cooling system for tempering and cooling.

1. 1. Flat cooling section

The alloy sections and steel sheets that we are using are tempered metals to avoid any possible deformation due to heat welding. And this ensures effective air distribution. Rational nozzle aperture and arrangement of air hole guarantee the glass even cooling. The upper and lower quenches are linked and combined with individual drives, which can actually control the accurate height for the air nozzles of quenches. Matched with balance control of upper and lower air amount, the top and bottom of the glass can get the best air pressure on both sides, so as to ensure the flatness of tempered glass.

1. 1. Electric control system

The control system includes the followings:
Process parameters storage and recall, such as glass thickness, size, color, glass type, and may be different sources of float glass and etc. Whenever you temper a new order for different thickness, size, color, type, source and etc., you just enter the process parameters, and the system will save these process data. Next time, when you have the same order, you can recall the data, and the machine will automatically use the stored processing data to produce.

Taiwan Advantech industrial control computer (IPC) and I / O output control card are adopted. I/O.
The temperature acquisition accuracy is between ±2ºC 
One-click restoration function of control system
Automatic preheating function
After the shift of a day, the furnace will be in standby status; an average of 15°C/hour will be lost in normal weather conditions. The ceramic rollers will be kept running. And ahead of working time on the next morning, the system can start automatically to heat up to the desired working temperature until the operator begins the production. This needs around 30min.

The main drive control system is accomplished by the inverter system, which is controlled by a computer. Control for roller driving system. (Note: the driving belt mode for the heating section adopts [round belt] and for the quenching adopts [round belt] mode)

The main screen page is displayed on the monitor during normal production. The contents displayed directly in English (or other available languages) are for the status of glass in the furnace, driving system, temperature at each zone, time of heating, quench, and cooling, set point of fans, and length sum of pieces of glass in the furnace. This screen is for the operator's notice.

The process parameter screen records when the button is pressed by the operator, temperature

PLC has a reserved communication interface, which provides the possibility for future factory automation upgrades.
