4. Conveyor device: bevel gear is adopted for steady and synchronous transmission.
5. Water circulation system: water sprayed out to the brushes will return to the tank and be reused by circumfluence thus save water consumption.
6. Control system: all function buttons are separated and clearly marked on the control panel. Conveyor device uses transducer to adjust the transmission speed. Glass thickness and transmission speed will be showed on the digital display.
Laminated glass is made of two or more pieces of glass panes, which are laminated with PVB interlayer under high temperature and high pressure. Laminated glass production line is necessary equipment for construction glass, decoration glass, wind-screening glass and bulletproof glass.
The whole full automatic laminated glass production line, we often call it lamination line, laminated glass line. It consists of automatic loading machine, washing and drying machine, Transition conveyor (¢ñ.¢ò.¢ó) Automatic positioning station£¬ Automatic sucker transferring unit, Assembling table, PVB film unwinding machine, Heating and pre-pressing machine, Unloading tilting table and Autoclave. There are two kinds of heaters: Ordinary quartz heater and IR heater. The whole line is PLC controlled with high efficiency, safety, reliability, and easy operation. It has serious technical features as following:
1. The solid and efficient intelligent control system: the whole line is centralized control by industrial computer assisted in PLC and monitor display/operation, Conveyors of the whole line are centrally controlled.
2. Designing and producing focus on safety regulations and energy saving programs. We can satisfy any kinds of requirement of consumer to produce the machine what the want.
3. Software programs by ourselves can satisfy any range of glass types and sizes for processing. The glass sheets are guaranteed to have a smooth and coherence without any crash and scratch in fast or slow speeding delivery.
4. Automatic loading Machine has different demand such as single/double side(s) and single/double/multi working station(s) to load the glass sheets into the working line.
5. Glass Washing & Drying Machine focuses on appropriate design and convenient operation. Top section including top brushes, pressing rollers and air knives can be adjusted automatically or manually, the maximum of distance can reach 400mm.
6. Automatic Positioning Station in cleaning room realizes the glass accurate positioning. The conveying roller works the crosswise positioning and the synchronous belt works the lengthwise one. After the accurate positioning the glass sheet will be taken by Overhead Transferring Unit to assembling station.
7. Overhead Transferring Unit in cleaning room can be set travel distance is based the glass size. It ensures the assembling accuracy within ¡À0.5mm.
8. Extension Assembling Table can extend the working station according to glass size. PVB Film Unwinding Machine can wind /unwind the film automatically. The maximum capacity is to load 5 rolls.
9. The pre-press rolling machine has high value design and factions for pre-press rolling glass bond. The heating zones in it are fitted with IR emitters which can be adjusted by controlled silicon to realize no contact rapid alternation. Combined with PWM system to regulate the IR emitter the rays will be perfectly absorbed by the film. The main heating zones are designed to have air cycle system to realize uniform temperature distribution so that to be adapted perfectly to the different types of glass. The pressing roller I and II can automatically (option) adjust the gap to meet the glass thickness. The top structure with cylinder supplies upper press. Well balanced heating and regular air evacuation are guaranteed for good pressing consideration. The structure is reasonable for min movement after pressing.
10. Tilting Table for Unloading makes the glass sheet from conveyor to approx. vertical situation that is easy for clamp lifting.
11. Autoclave is controlled by industrial computer assisted with digital control card and digital display to realize real-time control. It ensures safety, convenient operation and faster cooling per circle that outside wire connecting and know-how circulation, water cooling system.
Semi-automatic laminated glass production line, we often call it lamination line, laminated glass line. This line includes different equipment such as washing machine, PVB unwinding machine, laminating positioning and transmission machine, movable scissor sucking hanger, pre-laminating and pressing section and autoclave. There are two kinds of heaters: Ordinary quartz heater and IR heater. The whole line is PLC controlled with high efficiency, safety, reliability, and easy operation.
£¨1£©The whole line is centralized control by PLC .
£¨2£©Washing and drying machine is the core equipment of the whole line.
The upper Rubber rollers, brush rollers and air-knives etc. can be adjusted on the panel and digital displayed according to the thickness of glass to be processed. The upper section of the machines can be elevated by 400mm for convenience of cleaning and repairing. The Brush Rollers are driven by motors with upper and lower separately.
Allocation of one soft brush and two hard brushes (can be lifted when needed) in the upper washing sector is designed for washing hard low-e glass, coated glass without damaging the coating.
Three Stainless steel air-knives, the blower equipped with muffle cotton and air feeding filter screen pack ensures plenty of air, less noise and the good drying effect.
£¨3£©In the laminating room the laminating table, brace of the up-down device, positioning cylinder, PVB film unwinding machine, movable scissor cup suction hunger, convenient for processing of large and big glasses.
Every single processing glass can be conveyed in a higher speed to enter into the Pre-laminating and pressing section and regulated automatically the speed to running at the same speed with the Pre-laminating and pressing section which can make room for the next pieces of glass which improves the running efficiency of the Line.
£¨4£©Pre-laminating and pressing section has reasonable structure.
The integrity is controlled in laminating room with its stable running function.
Speed regulation is frequency variable.
Space/distance between two great squeezing rollers is set by industrial computer assisted by PLC with monitor displayed. The great squeezing rollers are driven by reducer separately.
The heating elements adopt Quartz -Heaters. Temperature is zone control.
£¨5£©Autoclave is a specialized machine for production of laminated, anti-bullet and anti-bombing glass. This machine will melt the PVB film and combined two layers or more than two layers glass by high temperature and high pressure.

Heat soak furnace, we often call it tempering furnace. It is the necessary equipment for producing tempered glass.
Why tempered glass break?
Tempered glass could have spontaneous breakage without receiving any external force, which is the nature of tempered glass. The reason comes from nickel sulfide inside the glass. Nickel sulfide is ¦á¡«nis in high temperature during the heating section. When cooled rapidly, ¦á¡«nis can not change correspondingly to ¦â¡«nis of low temperature. The morphic transformation will last for ten of years which lead to spontaneous breakage.
What is heat soaking?
Heat soaking is a destructive process in which a pane of tempered glass is subjected to temperatures up to 280¡ã c for several hours over a specific temperature gradient to induce fracture. This test insures that if there is probability of breakage then the infected panes break inside the furnace at the factory itself. Up to 95 % nis infested panes are usually destroyed inside the heat soak chamber at the factory premises and hence reduce the chances of onsite breakages. The machine is characteristic of computer in-process monitoring and controlling, multi curve display, data storage, record check and curve printing. Extended functions like low temperature frit drying and pre-pressing of bending lamination glass. Customized machines are available.
