Soften drawer oven of Acrylic sheets
Soften drawer oven of Acrylic sheets. The working time is 5 minutes. The temperature is 175 degrees. The product weight is 1 kg.
The equipment has the system of manual and automatic operation, which adds PLC control for touch screen and facilitates of the docking with the robot in the future.
ⅠThe main technical parameters of the drawer type oven for softening acrylic sheets
1、Inner tank size: single inner tank size: 2400* 350 * height (portal height: 180) * 1200mm deep, divided into three layers, independent temperature control;
2、External dimension (about) : 3100* 1650* deep 1920mm (excluding door);
3、Temperature range:Indoor temperature~'250℃ adjustable;
4、Temperature fluctuation:≤±1℃;
5、Temperature uniformity:≤±3℃(no load test);
6、Heating rate:≤8℃/min;
7、the enclosure temperature: enclosure surface temperature not to exceed 30 ° C, the crack temperature less than 60 ° C.The oven body surface is marked with high temperature risk;
8、Mode of air circulatiing: a large amount of air force in horizontal circulation ≥300 m3 / h;
9、Three-phase five little system,380V,50HZ
10、Gross power:40KW around;
ⅡThe constructional features of the drawer type oven for softening acrylic sheets
1、Enclosure material: it is made of 2mm thick Q235 cold-rolled steel sheet (with best strength, plasticity and welding comprehensive performance), which is bent and welded.
2、Inner liner material:Plate made of 1.5mm thick SUS201 mirror stainless steel
3、The box is made of 50*50*3mm Angle iron to maintain the bearing strength of the inside and outside of the chamber, and keep the heat expansion and cold shrinkage coefficient to prevent the frame from deformation
4、Sealing material: the sealing strip is made of silica gel, which can withstand temperature without deformation, and the door and inner tank are double-layer sealed to enhance the sealing effect;
5、Door: the door is divided into 3 layers, each level is opened individually, and pneumatic cylinder can open the door automatically and manually.
6、Flat tray of Drawer:Flat tray of Drawer can be pulled out larger than 800mm, the door and the tray can be automatically opened independently, and the control method is separate and automatic, which is controlled by PLC, and the I/O interface is reserved to facilitate the docking with the robot in the future.
Ⅲ The control system of the drawer type oven for softening acrylic sheets
1、Air transport motor: 6pcs 0.75kw Taiwan air transport motor of datong explosion-proof;
2、Wind wheel: 10.5-inch stainless steel air wheel of multi-wing ;
3、Heating pipe: adopt u-shaped heating pipe of SUS304 stainless steel made in Taiwan, with heat radiator, which can make the temperature of heating pipe evenly distributed;
4、Method of Air heating: the air is filtered by the air inlet of the oven and then fed into the air groove of the heating pipe. The air is circulated inside the oven after being heated, and the waste gas is discharged from the exhaust port
5、Protection thermostat of Ultra-temperature : the thermostat is an electrical intelligent thermostat with PV and SV function of dual LED display. When the temperature exceeds the set value of ultra-temperature protection thermostat, the heating power is automatically cut off.
6、Time control:Time controller of LED digital display can be set to the maximum time of 99 hours, and the unit can be arbitrarily switched to hours, minutes and seconds;
7、Control of heating tube: each group of heating tube is controlled by SSR solid relay;
8、Temperature sensor: standard type of Omron 3-meter , k-type thermocouple;
Ⅳ The function of the drawer type oven for softening acrylic sheets
1、Over-temperature alarm: when the actual detection temperature exceeds the setting value of the protection thermostat of over-temperature , automatically cut off the heating power and double protection function;
2、Audible and visual alarm: alarm lamp with buzzer.
Ⅴ The enviromental condition of the drawer type oven for softening acrylic sheets
1、Enviromental temperature:-5℃-40℃
2、Relative humidity:≤85%RH;
3、Power supply:AC380V±10%,50Hz;
