Description

Technical Field

[0001] This utility model relates to the field of cardboard box production equipment, and in particular to a stacking device for unloading cardboard boxes. Background Technology

[0002] Cardboard boxes are commonly used as wrapping materials for goods or as protective outer layers for items. As an indispensable part of modern logistics, packaging cardboard boxes bear the important responsibilities of containing, protecting, and aesthetically pleasing products. After mass production, cardboard boxes need to be stacked, and cardboard box stacking equipment is one of the key pieces of equipment in the cardboard production process. Most existing cardboard box stacking equipment relies on conveyor belts to transport the boxes to the stacking position. To prevent misalignment and collapse during stacking, workers usually need to manually align the boxes before conveying them, which increases labor intensity and reduces stacking efficiency.

The end of the threaded cylinder away from the hollow plate passes through the enclosure of the conveyor belt and is movably connected thereto. The threaded cylinder is threadedly connected to the lead screw.

[0012] The end of the lead screw away from the threaded cylinder is rotatably connected inside the main body, and the lead screw is driven by a motor.

[0013] Preferably, the inner sides of both the connecting block and the hollow plate are fitted with rubber buffer pads.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model automatically aligns cartons during transport by using a flexible limiting plate, connecting block, telescopic plate and hollow plate together, eliminating the need for manual alignment and thus reducing labor and improving carton stacking efficiency.

[0016] 2. This utility model prevents the outer surface of the carton from being squeezed by a flexible limiting plate, a connecting block, and a buffer pad on the inner side of the hollow plate, thereby preventing the carton from deforming. Attached Figure Description

[0020] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model.

[0021] This application discloses a stacking device for feeding cardboard boxes, as shown in the attached diagram. Figure 1 As shown, it includes a main body 1, a conveyor belt 2, and a carton alignment mechanism;

[0022] The conveyor belt 2 is installed inside the main body 1. Fences are set on both sides of the conveyor belt 2. The carton alignment mechanism is set on the top of the conveyor belt 2. A robotic arm for clamping the carton is installed at the outlet of the conveyor belt 2.

[0023] As attached Figure 2 As shown, the carton alignment mechanism includes a flexible limiting plate 3, a connecting block 4, a telescopic plate 5, a hollow plate 6, a threaded cylinder 7, and a lead screw 8.

[0024] There are two flexible limiting plates 3, and the ends of the two flexible limiting plates 3 away from the robotic arm are fixedly connected to the fences on both sides of the conveyor belt 2 respectively.

[0025] The connecting block 4 is made of rigid material and is fixedly connected to the movable end of the flexible limiting plate 3;

[0026] The telescopic plate 5 is fixedly connected to the end of the connecting block 4 away from the flexible limiting plate 3, and the other end of the telescopic plate 5 is movably connected to the inside of the hollow plate 6.

[0027] The threaded cylinder 7 is fixedly connected to the hollow plate 6. The threaded cylinder 7 has a prismatic structure. The end of the threaded cylinder 7 away from the hollow plate 6 passes through the fence of the conveyor belt 2 and is movably connected thereto. The threaded cylinder 7 is threadedly connected to the lead screw 8.

[0028] The end of the lead screw 8 away from the threaded cylinder 7 is rotatably connected inside the main body 1, and the lead screw 8 is driven by a motor.

[0029] Rubber buffer pads are installed on the inner sides of both the connecting block 4 and the hollow plate 6.

[0030] Working principle: After the worker places the carton on the conveyor belt 2, the conveyor belt 2 is started. Then the motor is started, and the motor drives the lead screw 8 to rotate. The lead screw 8 drives the threaded cylinder 7 to move. The threaded cylinder 7 drives the hollow plate 6 to move. The hollow plate 6 drives the telescopic plate 5 and the connecting block 4 to move. The connecting block 4 drives the flexible limiting plate 3 to bend, and at the same time stretches the telescopic plate 5 until the hollow plate 6 contacts the outer wall of the first carton. At this time, the flexible limiting plate 3, the connecting block 4, the telescopic plate 5 and the hollow plate 6 together form an arc-shaped limiting component. The flexible limiting plate 3 and the buffer pad prevent the carton from being clamped and deformed, so that the subsequent cartons gradually move along the limiting component between the two hollow plates 6, thereby automatically aligning the cartons. Then the robotic arm stacks the cartons, eliminating the need for workers to manually align the cartons, thus reducing the workload and improving the efficiency of carton stacking.

[0031] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
