The Jinan LIJIANG Laminated Glass Production Line

Brief Introduction

1) This set of production lines consists of a semi-automatic loading table, glass washing and drying machine, film positioning conveyor, walking suction cup hanger, electric pvb film rack, transition conveying table, pre-pressing preheating machine, infrared autoclave, gas storage tank, air compressor (including a refrigerated dryer, three-stage filter) and other components.

2) The whole set of equipment has a reasonable layout and low power consumption and can be customized according to customer requirements. PLC+touch screen is used to automatically control the operation.

3) The whole line is about 45 meters long.

Complete furnace forced convection:

The circulation formed by the convection fan is completely carried out in the furnace body, without heat loss due to convection, and the energy-saving effect is good;

Specially designed convection fan, the high-temperature performance is more stable and reliable, and the convection effect is excellent; the fan itself is air-cooled;

The advanced design of the convection circulation structure and the reasonable selection of materials ensure that the heating speed of the glass is faster and more uniform;

The operation speed of the convection fan is controlled by the frequency converter and given by the computer so that the upper and lower surfaces of the glass are heated uniformly, which greatly improves the product quality;

Stronger processing ability and higher efficiency, in addition to processing all kinds of ordinary glass, it is especially suitable for processing Low-E glass;

The interior of the furnace is made of high-quality materials, which effectively controls the generation of various particulates and the resulting impact on the quality of the glass;

Using industrial computers and PLC control, the whole machine has a high degree of automation, good stability, simple operation, and high production efficiency.

The motorized PVB glass film transport rack

This Motorized PVB Glass Film Transport Rack is supporting equipment for the production of laminated glass, the purpose is to meet the requirements of large-scale production and reduce the labor intensity of operators. 

Main features: A suction cup frame is installed on the upper part of the conveying roller table in the glass lamination room, and corresponding positioning switches are installed on the rack roller table and the conveying roller table. When the front piece of glass is sent to the positioning switch, the glass stops, the glass is sucked and lifted by the suction cup frame, and the second piece of glass is transported to the positioning switch. When the glass stops, the suction cup frame is smoothly lowered to overlap the two pieces of glass, thus completing the synthesis craft. It can hold 3 rolls of film, and the motor rotates, so that the laminated glass manufacturer saves the labor cost of a glass handling operator.

The heating and cooling of the glass in the furnace are controlled by the frequency conversion speed control system, with high precision and good synchronization, to avoid scratches on the glass during the movement.

The heating method adopts a spiral matrix structure, and the furnace temperature is controlled in different areas; the heating elements are finely divided, with reasonable design, unique structure, and long service life, which ensures the accuracy of temperature control and the balance of the temperature of each part in the furnace, so that the temperature control can be optimal. condition.

Temperature measurement adopts distributed remote thermocouple temperature measurement module, which has the strong anti-interference ability and high-temperature measurement accuracy; the on-off of furnace wire is controlled by board card and solid-state relay, with stable and reliable performance and no noise.

The heating furnace is designed with an automatic temperature homogenization device, which can be adjusted according to different specifications and varieties to ensure the uniformity of glass heating. Glass products are flatter, higher in quality, and suitable for tempering more types of glass, such as coated glass and heat-reflecting glass.

The fully enclosed heating furnace body adopts imported high-quality thermal insulation materials, with good thermal insulation performance and low production energy consumption.
