[0002] The feeding device is an important equipment on the packaging carton production line. It is responsible for stably and efficiently conveying the packaging carton raw materials to be processed to the next process. The common feeding device is mainly composed of a transmission frame, a conveyor belt, a transmission group, a servo motor, a conveyor roller and a control system. The specific process of the feeding device conveying the packaging box is as follows: the packaging carton raw materials to be processed are placed on the conveyor belt under the transmission frame, and the control system drives the servo motor to input a stable working current, which is conveyed by the transmission group and drives the conveyor roller to rotate, thereby driving the conveyor belt to rotate synchronously, and then driving the packaging boxes on the surface of the conveyor belt to enter the next process;

[0003] During the actual operation, we found that the feeding device had the following problems: The feeding device was not adaptable enough. The main reason for this problem was that although the feeding device was usually suitable for packaging paper box materials of various specifications and sizes, it might not be able to adapt well in some extreme cases, such as very large paper boxes, which might lead to problems such as poor transmission or jamming, and thus reduce the overall production efficiency of the packaging paper boxes; at the same time, during the actual production process of the packaging paper boxes, the paper boxes need to be inspected for quality, which is mainly done manually.

[0042] In the embodiment of the present application, electromagnetic valves are installed in the multiple groups of gas outlet holes of the multi-hole gas outlet pipe 707 to control the flow direction of the gas.

[0043] The specific working process of the embodiment of the present application is as follows: when the packaging carton is being conveyed, the electric-controlled hydraulic column 705 inputs a stable working current to drive the limit plate 7 to move to a distance suitable for the packaging carton. At the same time, the air pump 703 inputs a stable working current to generate compressed air and deliver it to each group of air grooves. When the conveyor belt 3 transports the packaging carton, if the packaging carton transported on the surface of the conveyor belt 3 is offset, the packaging carton contacts the surface of the rubber ring 701 on one side, and the rubber ring 701 is deformed.

When the quality inspection unit simulates that the packaging carton meets the production standard, the weight sensor 5 generates simulated weight data and integrates the data into the production standard range. The quality inspection unit compares the real-time weight data with the standard range. When the real-time weight data is not within the range, it is determined that the packaging carton does not meet the production standard.

[0047] The regulating unit simulates the simulated air pressure data generated by the pressure sensor when the packaging carton is normally transported on the surface of the conveyor belt 3, and integrates the simulated air pressure data to form a threshold range. The regulating unit compares the real-time pressure data with the threshold range. When the real-time pressure data is not within the threshold range, it is determined that the packaging carton transported on the surface of the conveyor belt 3 has a positional deviation.

[0048] The specific workflow of this application is as follows:

[0049] Step 1: The packaging carton is transported to the surface of a group of conveyor belts 3, and the power supply mechanism 2 inputs a stable working current to drive the two groups of conveyor belts 3 to synchronously transport the packaging carton. During the transportation of the packaging carton, the weight sensor 5 detects the weight of the packaging carton, and the weight sensor 5 generates corresponding weight data and transmits it to the control system. The control system analyzes the weight data to determine whether the production instruction of the packaging carton meets the standard. When it is determined that the packaging carton does not meet the production standard, the packaging carton moves to the upper surface position of the electric control lifting frame 4, and the electric control lifting frame 4 inputs a stable working current to drive the packaging carton to move out of the surface of the conveyor belt 3, so as to facilitate the next step of processing;
