Product details

Product Description

DBZB-AF7332 Fully Automatic Flip-Mold Plastic Cup Thermoforming Machine adopts advanced positive and negative pressure forming technology. The mold flipping system is fully driven by servo motors and coordinated with two pairs of conjugate cam linkage mechanisms to realize mold table flipping, lifting, and cutting with high precision. This newly developed machine is designed to meet the requirements of high output, low energy consumption, high stability, and a high level of automation. It is an ideal solution for the production of medium- and high-capacity disposable plastic cups.

Machine Features

		1. Unwinding Station Automatic sheet feeding system with photoelectric sensor control to start and stop the feeding motor, reducing the load on the servo-driven conveying system. The machine adopts a dual-sheet loading station, allowing a maximum sheet roll diameter of 1000 mm and maximum roll weight of 600 kg, ensuring continuous production and reducing downtime during material replacement.

2. Sheet Conveying System a. The feeding chain adopts double-row toothed roller chains for stable transmission. Cooling water channels are integrated into the chain guide rails, providing high cooling efficiency, low water consumption, and long service life. b. The conveying system is driven by a servo motor with sprocket transmission, ensuring high feeding precision and fast start-stop response. c. The chain rail adopts a semi-open structure, making it easier to adjust the chain rail tension.

		3. Heating Section a. The heating furnace length is 2250 mm, divided into 7 heating zones. It adopts German ELSTEIN heaters, with 36 upper heating zones and 12 lower heating zones, totaling 48 temperature control zones. Temperature is automatically controlled using a temperature control module with solid-state relay (SSR) contactless output, ensuring stable operation and high precision with a temperature control accuracy of ≤ ±1°C. b. The heater adopts embedded ceramic far-infrared radiation elements, providing high thermal efficiency and reliable safety performance. c. An infrared sheet sag detection alarm system prevents excessive sheet dropping. This helps avoid overheating and prevents the sheet from melting into the heater, reducing fire risks.

4. Forming and Cutting Station a. The power transmission mechanism adopts two pairs of conjugate cams driving linkages to complete mold table flipping, lifting, and cutting operations. The main motor directly drives the transmission system, ensuring smoother mold lifting and lower cutting noise. b. The mold table guiding system adopts a four-guide-column structure, offering high rigidity, accurate guiding performance, and strong wear resistance, which helps extend the service life of the cutting molds. c. The machine adopts a low center-of-gravity design, ensuring stable operation and providing an ergonomic operating height for easy monitoring and operation.

		5. Lower Mold The mold water and air circuits are directly supplied through the mold table, allowing quick mold installation. The mold layout is optimized for better structure and appearance. The stretching system is driven by a servo motor with a high-precision ball screw transmission, allowing direct setting of the stretching length and accurate positioning.

6. Upper Mold Head The upper mold table is designed with a lifting adjustment mechanism, driven by a motor and sprocket system, allowing convenient height adjustment. The cutting knife depth can be adjusted directly to accommodate different mold closing heights, with a maximum adjustment range of ±5 mm

		7. V-Type Cup Flipping Device The cup receiving system is driven by a servo motor and equipped with a self-developed V-type cup flipping device, enabling fast cup suction, flipping, and stacking. It is suitable for cups of different diameters and heights.

8. Automatic Cup Collection System Cup sweeping and pushing are controlled by servo motors. When the preset counting quantity is reached, the formed cups are quickly swept onto the conveyor belt according to the product row arrangement.

		9. Finished Product Conveyor The finished cup conveyor is driven by a servo motor. The system collects products according to the forming arrangement and transports finished cups out of the machine automatically.

10. Waste Material Rewinding System A waste rewinding unit is installed at the rear of the machine. The maximum rewinding diameter is Ø1000 mm, allowing convenient scrap roll replacement and efficient waste collection.
