Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and more specifically relates to an integrated injection molding and packaging device for a plastic lunch box. Background Art

[0002] At present, in order to improve the injection molding production efficiency of lunch boxes, automated injection molding and unloading are generally used. The machine uses an automated manipulator to take out the lunch boxes that have been injection molded from the injection molding machine and stack them on the unloading plate on one side of the injection molding machine. They are then manually transferred and stacked in a temporary storage box. When the temporary storage box is full, it is transferred to a packaging machine. Manually take out the stacked lunch boxes from the temporary storage box and move them to the packaging machine for packaging. The process has a high labor cost, high operation repetitiveness, and workers are prone to fatigue. Utility Model Content

[0005] Furthermore, the clamp includes two connecting plates and two clamping plates, the two connecting plates are respectively connected to the piston blocks of the clamp cylinder, the clamping plates are vertically connected to the connecting plates, and the connecting sides of the clamping plates are bent outward to form connecting pieces, which are connected to the connecting plate bolts and nuts.

[0006] Furthermore, rubber clamping blocks are arranged on the facing sides of the two clamping plates.

[0007] Furthermore, the connecting plate is provided with a long strip-shaped connecting groove, and the connecting bolts are located in the connecting groove.

[0008] Furthermore, two rubber clamping blocks are arranged on the clamping plate, one of which is fixedly connected to the clamping plate, and the other is adjustably connected to the clamping plate, so as to adjust the distance between the two rubber clamping blocks.

[0009] Compared with the prior art, the beneficial effect of the utility model is that the lunch boxes produced by the injection molding machine are automatically stacked on the second conveyor belt by an automatic grasping manipulator. When a certain stacking quantity is reached, the second conveyor belt moves to transfer the lunch boxes to the first conveyor belt. The clamping claw is driven by the three-axis moving mechanism to align with the lunch box and descend, and then the lunch box is clamped by the clamping claw cylinder. The clamped lunch box is transferred to the packaging machine through the three-axis moving mechanism, thereby realizing the automatic transfer of the lunch box from the injection molding machine to the packaging machine, greatly saving manpower and reducing labor costs.
