The storage bucket is convenient for placing any goods conducive to production

The section includes a combined steel frame, a transmission system, a landing gear, a photoelectric switch, etc

The drive motor of the upper plate is driven by frequency converter, and the placed glass is transmitted to the photoelectric switch of front furnace door of heating furnace, and the furnace is ready for entering. During the furnace entering, the frequency converter drives the motor to drive the roller table to run at high speed and transport the glass to the heater for heating. The length of glass is accurately measured and recorded by photoelectric switch and furnace encoder. The distance of glass loading can be changed by human-computer interface according to the size of glass. The universal ball table mechanism with pneumatic device can control the lifting and lowering manually, which is more suitable for the large glass mounting.

Furnace body

The heating furnace is a steel structure with upper and lower sections. The upper furnace body can rise and fall freely through the furnace top lifting mechanism. The lifting height is 450mm, which is convenient for maintenance and cleaning. High density ceramic fibreboard is used as thermal insulation material of furnace body, and the surface is treated with high temperature resistant adhesive. A layer of magnetized high aluminum plate is laid inside the furnace to ensure that no impurities will fall, causing pockmarks and defects of products. Each convection fan adopts frequency conversion control, which can be controlled separately. According to the heating principle of glass, automatically adjust the wind pressure. The convection fan is arranged in the middle of the furnace top, and the double air outlet design is adopted to make the air pressure more uniform. The motor bearing adopts air cooling to extend the bearing life.

Double belt drive, better synchronization, higher safety performance.

Upper internal circulation convection fan
Each convection fan adopts frequency conversion control, which can be controlled separately. According to the heating principle of glass, automatically adjust the wind pressure. The convection fan is arranged in the middle of the furnace top, and the double air outlet design is adopted to make the air pressure more uniform. The motor bearing adopts air cooling to extend the bearing life.

Internal stainless steel convection system

The installation of each furnace wire is independent, and the removal and replacement of faulty furnace wire will never damage other furnace wires. The furnace wire has a single point control function. Each furnace wire has a separate thermocouple for temperature measurement, and can set the temperature and power separately to make the temperature in the furnace as uniform as possible.

The lower radiant plate is corrugated to increase the strength of the radiant plate, without deformation at high temperature

The roller hole is made of customized insulating bricks with accurate diameter, small gap, durable, heat preservation and easy replacement.

The outer sealing ring is designed so that the temperature inside the furnace will not emit heat through the gap between roller joints
The high quality ceramic roller is used for furnace body transmission, with high surface finish and long life. The ceramic roller is driven by circular belt, and the frequency conversion speed control ensures the synchronization and stability of the movement. Equipped with roller conveyor, installation of roller table is convenient and fast.

The transmission shaft of the furnace body adopts the plating shaft, with smooth surface quality and accurate straightness. V-groove is opened between 45 ℃ in the shaft length direction to fix the belt pulley. The belt pulley is easy to install and firmly fixed. The shaft head adopts the outer square, the coupling adopts the inner square, the connection is more firm, the transmission between the shafts is frameless, so as to avoid the collision of glass in the furnace

The lifting mechanism of the upper and lower air grates can adjust the height of the upper air grates independently, which makes it more convenient to adjust the flatness of the glass. The small air box is formed by bending a cold plate at one time. The air outlet is made of aluminum alloy cold drawn on a single air box and sealed with glue. The roller table is made of high-quality cold drawn steel rolls with thick wall. The rope winding part of each steel roll is slotted for glue treatment. The high temperature resistant rope is closely bonded with the steel roll by high temperature glue and is baked for heat treatment. Chain drive, better synchronization.

The small bellows can be cleaned, and each small bellows has separate baffle at both ends, which can be disassembled separately. It is convenient and fast to clean the internal stolen goods

The fan is of integral frame type. Anti vibration cushion support. On site installation saves time, labor and place
