[0002] Plastic cans are small, sealed containers made primarily of plastic or plastic composite materials. They consist of a can body and a lid and are widely used in the packaging of food, beverages, cosmetics, and other products. The can body is often reinforced with materials such as paper and aluminum foil, while the bottom and lid are mostly made of plastic or metal. The structure is divided into two types: laminated composite material cans (square can body) and multi-layer wound cans (cylindrical can body). Zero-PET plastic cans use food-grade PP material, which is safer. After existing zero-PET plastic cans are injection molded into preforms, the preforms need to be manually placed one by one on the feeder of the blow molding machine, which increases the overall processing cost.

The raw liquid in the molding groove 213 is finally cooled to form a can preform 214. With the assistance of the hydraulic cylinder on the first support frame 26, the first support plate 24 is driven to slide to the left in the sliding groove of the first support frame 26 through the hydraulic rod. This causes the second mold 215 to separate from the first mold 212. The connecting T plate 25 moves to the left and contacts the left side of the first support frame 26. Finally, the connecting T plate 25 pushes out part of the can preform 214 through the push rod 23, which facilitates the clamping and disassembly of the can preform 214 later. like Figure 3 , Figure 7 and Figure 8As shown, an upper unloading structure 3 is installed on the injection molding structure 2.

With the assistance of the electric telescopic rod 373 on the upper side of the fixing plate 372 on the fourth support plate 371, the clamping plate 374 is moved and clamps the can preforms 214. Similarly, with the assistance of the hydraulic cylinder, the can preforms 214 on the clamping assembly 37 are moved upwards to the desired position via the hydraulic rod and telescopic rod 337.

The heated can preform 214 enters the blow molding machine body 5 and is blown through the blow molding tube 395 with the assistance of the blow molding machine body 5. The blown PET plastic can body enters the detection box 61 with the assistance of the second rotating component 62. The machine rotates the zero-PET plastic can, and the camera 63 transmits the captured images to the processor for processing.

When a defective zero-PET plastic can is detected, the robotic arm 642 and robotic gripper 643 on the top plate 641 are activated with the assistance of the PLC control device. The defective can is then clamped and placed on the placement table through the rejection outlet at the rear of the inspection box 61.
