Description

Technical Field

[0001] The utility model relates to the technical field of carton packaging, in particular to a foam carton packaging line. Background Art

[0002] Floral foam is commonly used in flower planting as a potting material. During production, the floral foam is generally stacked and packaged for easy transportation and sale. The stacking and boxing and sealing of the foam are usually done manually or using packaging equipment.

[0003] For example, Chinese patent application CN106043762B discloses an automatic foam packing machine for stoves, which includes a frame on which a gantry-type robotic arm and a driving mechanism for driving the robotic arm to move in the X and Y directions are provided. A foam clamp is installed at the lower end of the robotic arm, and a foam positioning device, a bracket, and a material incoming roller group fixed to the bracket are provided below the robotic arm. A carton positioning device and a carton opening device are installed on the bracket, and the carton opening device is provided above the carton positioning device.

[0004] However, when the stove foam automatic cartoning machine is used, the robotic arm needs to move back and forth, and the clamp cannot pick up the stacked materials. It can only pick up one at a time and stack them repeatedly, which is inefficient. Moreover, due to positioning problems, it is difficult to adapt to products of different sizes.
