Core forming principle
Adopts conjugate cam flipping + curved guide rail mold opening and closing technology. The lower mold table can flip at high speed (about 75°), combined with servo motor positive pressure stretching forming. Compared with traditional equipment, flipping forming makes the sheet material experience more uniform stress, effectively solving the problems of overly thick cup bottoms and thin cup walls, resulting in products with full edges and consistent wall thickness.
Key structure and process
- Servo sheet feeding system: servo motor chain drive, with automatic tensioning track to prevent sheet drooping, ensuring high feeding accuracy.
- Zonal heating system: tunnel-type diffuse radiation heating, imported heating tiles, independent temperature control for upper and lower drying tunnels, ensuring uniform heating and fast response.
- Flipping mold table: servo + hardened gear surface reduction drive, conjugate cam control for flipping and opening/closing, operating at high speed and stability (up to 30 molds per minute).
- Positive pressure forming and punching: dual screw rod balanced pressing, depth adjustable; integrated punching of upper and lower mold blades, resulting in burr-free products with fewer stuck cups.
- Automatic stacking: V-shaped robotic arm suction cup stacking, automatically sorting, counting, and outputting.
Application scenarios
- Regular cups: water cups, cold drink cups, jelly cups, ice cream cups
- Bowls / boxes: instant noodle bowls, takeout boxes, shallow meal boxes
- Lids / dishes: ordinary cup lids, bowl lids, plastic dishes
