[0037] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0038] Reference Figures 1-5 For the first embodiment of the present application, a paper feeding mechanism of a paper feeding machine for conveying paperboard, comprising a paper feeding frame 1; a storage bin 2 is arranged on the paper feeding frame 1, the storage bin 2 has a discharge port 3 at the bottom, the storage bin 2 is used for storing paperboard to be conveyed; a suction nozzle 4 is slidably arranged on the paper feeding frame 1, the suction nozzle 4 is close to or away from the discharge port 3 after sliding, the suction nozzle 4 is used for adsorbing the paperboard and driving the paperboard to leave the storage bin 2; a crankshaft 5 is rotatably arranged on the paper feeding frame 1; a connecting rod 6 is eccentrically hinged to one end of the crankshaft 5, and the other end is hinged to the suction nozzle 4, when the crankshaft 5 rotates, the connecting rod 6 drives the suction nozzle 4 to slide.

[0039] In this embodiment, the storage bin 2 is used to store paperboard, which is neatly stacked in the storage bin 2. A small hook at the bottom of the discharge port 3 of the storage bin 2 supports the neatly stacked paperboard in the storage bin 2. When the paperboard needs to be discharged, the suction nozzle 4 will suck the lowermost paperboard and slide near the discharge port 3. The storage bin 2 is usually inclined, so that the paperboard is overlapped on one side of the discharge port. After the suction nozzle 4 adsorbs the paperboard, it will slide backward for a certain distance. When the suction nozzle 4 slides backward to the specified distance, it will temporarily stop sliding, waiting for the paperboard to completely leave the discharge port 3 of the storage bin 2. After the paperboard completely leaves the discharge port 3 of the storage bin 2 and falls down, the suction nozzle 4 will continue to transport forward to send the paperboard away from the discharge port 3, completing the transportation of the paperboard. After the transportation of a piece of paperboard is completed, the suction nozzle 4 will repeat the action to continue the transportation of the next piece of paperboard, ensuring the continuity of the transportation. The storage bin 2 and the slidable suction nozzle 4 are arranged on the paper feeding frame 1, and the suction nozzle 4 can adsorb the paperboard and drive it to leave the storage bin 2. This design can realize automatic paper feeding, improve the efficiency of paper feeding, reduce manual operation, and reduce labor intensity. Moreover, the direct adsorption of the suction nozzle 4 to the paperboard can avoid the problems of paperboard slipping and mispositioning that may occur in traditional paper feeding methods, greatly improving the accuracy and stability of paper feeding. In addition, this structure is compact, occupies small space, and is convenient to install and maintain. Through the eccentric hinge of the crankshaft 5 and the connecting rod 6, when the crankshaft 5 rotates, the other end of the connecting rod 6 can realize circular sliding, ensuring the stability of the working process and the continuity of the whole, improving the efficiency of the feeding.

[0040] As a further technical solution, the suction nozzle 4 has several, and further comprises:

[0041] The suction nozzle 4 fixed shaft is slidably arranged on the paper feeding frame 1, and the plurality of suction nozzles 4 are arrayed and spaced on the suction nozzle 4 fixed shaft. The plurality of suction nozzles 4 are slidably arranged on the paper feeding frame 1 through the suction nozzle 4 fixed shaft, and the other end of the connecting rod 6 is hinged with the suction nozzle 4 through the suction nozzle 4 fixed shaft.

[0042] In this embodiment, the suction nozzle 4 fixed shaft fixes a plurality of different suction nozzles 4, and the orientation of the suction nozzle 4 is uniformly adjusted by the rotation of the suction nozzle 4 fixed shaft. The suction nozzle 4 fixed shaft is rotatably arranged on the paper feeding frame 1, and a plurality of suction nozzles 4 are arrayed on the suction nozzle 4 fixed shaft. The rotation of the suction nozzle 4 fixed shaft changes the inclination angle of the suction nozzle 4. This design not only facilitates better adaptation to the transportation of paperboards of different specifications, improving the universality of the paper feeding mechanism, but also allows flexible adjustment of the angle of the suction nozzle 4 according to the shape and weight of the paperboard, making the adsorption force distribution more uniform, thereby effectively preventing the paperboard from deforming or being damaged during transportation. At the same time, the adjustability of the angle also provides more adaptability for different types of paper feeders, increasing the application range of the paper feeding mechanism.

[0043] As a further technical solution, it also includes that the guide rods 9 are provided on the paper feeding frame 1, the sliding block 10 is slidingly arranged on the guide rods 9, and the suction nozzle 4 fixed shaft is arranged on the guide rods 9 through the sliding block 10. The suction nozzle 4 fixed shaft is rotatably arranged on the sliding block 10. After the suction nozzle 4 fixed shaft rotates, the inclination angle of the suction nozzle 4 changes, and the suction nozzle 4 fixed shaft and the sliding block 10 have damping therebetween.

[0044] In this embodiment, the arrangement of the guide rods 9 and the sliding block 10 can ensure the accuracy of the movement track of the suction nozzle 4 fixed shaft, improve the stability and precision of the suction nozzle 4 in absorbing and conveying the paperboard. The guide rods 9 provide a clear guide for the movement of the suction nozzle 4 fixed shaft, so that it always moves along the predetermined route, thereby avoiding the position deviation of the suction nozzle 4 and the paper feeding failure caused by the deviation of the suction nozzle 4 fixed shaft. The sliding block 10 limits the excessive movement of the suction nozzle 4 fixed shaft, further ensuring the accuracy and stability of the movement. Such design helps to reduce the rate of defective products, improve product quality, reduce maintenance cost and downtime of the equipment, and improve production efficiency. When the orientation of the suction nozzle 4 changes, the orientation of the suction nozzle 4 can be appropriately changed by applying an external force to overcome the damping rotating link 6, and when no external force is applied, the orientation of the suction nozzle 4 remains unchanged.

[0045] As a further technical solution, it also includes that the rotating driving member 11 is arranged on the paper feeding frame 1, and the first synchronous belt 12 is arranged on the crankshaft 5 and the rotating driving member 11, respectively. The rotating driving member 11 is used to drive the crankshaft 5 to rotate.

[0046] In this embodiment, the rotating driving member 11 is a servo motor, which drives the crankshaft 5 to rotate through the first synchronous belt 12, realizes effective power transmission, ensures the continuous and stable operation of the paper feeding action, and improves the reliability of the equipment. The use of the first synchronous belt 12 can not only effectively reduce the energy loss in the power transmission process and improve the energy utilization efficiency, but also has the functions of buffering and shock absorption, thereby reducing the noise and vibration during the operation of the equipment. At the same time, this transmission mode is simple and reliable, easy to maintain and replace, and reduces the operation cost and maintenance difficulty of the equipment.

[0047] As a further technical solution, it also includes that the gas distribution valve 13 is arranged on the paper feeding frame 1, the gas distribution valve 13 is used to control the work of the suction nozzle 4, and the second synchronous belt 14 is arranged on the other end of the crankshaft 5 and the gas distribution valve 13, respectively. The crankshaft 5 is used to drive the gas distribution valve 13 to work.

[0048] In this embodiment, the gas distribution valve 13 controls the operation of the suction nozzle 4, can accurately control the suction force of the suction nozzle 4, ensures the stable adsorption and conveying of the paperboard, and can flexibly adjust the working state according to the actual demand. The gas distribution valve 13 can adjust the suction force of the suction nozzle 4 in real time according to the parameters such as the material, thickness and size of the paperboard, so as to avoid the damage of the paperboard caused by too large suction force or the falling off of the paperboard caused by too small suction force. In addition, through the integration with other control systems, the gas distribution valve 13 can also realize the automatic paper feeding control, and improve the intelligent level and production efficiency of the whole production process.

Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced without departing from the spirit and scope of the present application.
