Product details

Product Description

The DBZB-Y7642 Fully Automatic Hydraulic Plastic Cup Making Machine is built with a heavy-duty steel frame and full steel base to ensure excellent stability during high-speed operation. It adopts a Taiwan Yuken hydraulic system for reliable mold opening and closing, combined with SMC pneumatic components for stable performance. The machine features inverter-controlled feeding, a pneumatic stretching system (optional Yaskawa servo), automatic lubrication, and a multi-zone ceramic infrared heating system for uniform temperature control. With its robust mold-clamping structure and precision guide pillars, the DBZB-Y7642 delivers stable operation and high-efficiency production for plastic cups.

Machine Features

		1. Unwinding Station The machine adopts an independent unwinding station with pneumatic loading. The sheet material is pulled forward by rubber rollers, ensuring stable and smooth feeding.

2. Conveying Section The sheet is transported forward by a servo motor, providing stable and precise feeding. The width of the guide rails can be adjusted to accommodate different sheet sizes. The rail side plates adopt a circulating water cooling system to control the rail temperature and extend the service life of the chains. The track chains are made of 65# manganese steel, offering higher strength, heat resistance, and elasticity compared with 45# steel.

		3. Heating Section The material is heated by upper and lower electric heaters. The long heating distance ensures the sheet is heated fully and evenly. The heaters are equipped with vacuum insulation cotton, providing faster thermal response, shorter processing time, and improved energy efficiency. When the machine stops, the heating box automatically moves out to the side of the machine, ensuring safety and protecting the material from overheating.

4. Forming Mold The upper mold is equipped with a built-in stretching head that stretches the material downward into a cup shape. Compressed air then presses the material into the mold cavity to complete positive pressure forming. The lower mold moves upward to close with the upper mold to finish the forming process. Cooling water is installed inside the cavity of the lower mold to accelerate cooling and enable rapid forming.

		5. Conveyor Transportation After the plastic cups are formed, they are blown out from the mold and fall onto the conveyor belt, which is connected directly to the cup stacking machine for continuous operation.

6. Cup Arranging and Stacking The cups are collected and stacked through the belts of the cup stacking machine. To ensure proper stacking, the cup rim diameter must be smaller than the cup height; otherwise, the cups cannot be arranged correctly.

		7. Scrap Edge Recycling The scrap edges generated after punching are pulled and discharged outside the machine for recycling.

8. Control System The machine adopts a Siemens PLC and touch-screen control system. The entire machine is driven by a servo system, ensuring stable operation and precise control.
