[0002] During the carton production process, traditional loading methods often rely on manual placement of the cartons to be processed in designated locations on the forming machine. This method is not only inefficient but also increases worker workload. While the degree of automation in carton forming machines continues to improve with the advancement of automation technology, existing loading devices often suffer from complex structures and inconvenient operation, making them difficult to meet the demands of efficient and stable production.

[0003] The utility model patent with authorization announcement number CN214776955U discloses a new carton forming machine, including a material collection rack, a forming part and a conveying mechanism. The forming part includes a machine base, a moving rod, a guide rod, a horizontal push rod, a longitudinal push rod and a glue injection rod; the moving rod can be slid along one side of the L-shape of the machine base, and a suction cup is fixedly provided on the side of the moving rod facing the material collection rack. The guide rod can be slid along the other side of the L-shape of the machine base, and the conveying mechanism is overlapped with the position where the guide rod moves out of the machine base. In the above device, a stack of unprocessed folding cartons is placed in a vertical state in the material collection rack. When the number of unprocessed cartons gradually decreases, due to the fixed position of the limit part, the remaining cartons will gradually tilt, affecting the adsorption effect of the suction cup on the cartons, thereby affecting the loading. Utility Model Content

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: a loading device of a carton forming machine, comprising a frame, a material receiving frame is provided at one end of the frame, the material receiving frame is used to hold the carton to be formed, a cavity for a single carton to be formed to pass through is provided at the bottom of the material receiving frame, a discharge assembly for controlling the carton to be formed at the bottom to pass through the cavity is provided below the material receiving frame, a conveyor belt for transporting the carton to be formed is provided at one end of the material receiving frame, a discharge plate is provided at the end of the conveyor belt away from the discharge assembly, a flipping assembly for controlling the discharge plate to rotate 90° to make the carton to be formed stand up is provided on the frame, a carton forming machine is provided at the end of the discharge plate away from the conveyor belt, and a material picking suction cup is provided in the carton forming machine.

[0006] By adopting the above technical solution, the cartons to be formed are placed in stacks in the material support rack, and the discharging component sends the cartons to be formed at the bottom from the cavity to the conveyor belt. The conveyor belt sends the cartons to be formed onto the discharge plate, and then the flipping component controls the discharge plate to flip 90° toward the carton forming machine to keep the cartons to be formed in a vertical state. Then the material picking suction cup absorbs the cartons to be formed and sends them into the carton forming machine.

[0007] The utility model is further configured as follows: the discharging assembly includes pulleys respectively arranged at both ends of the material support frame, a belt is sleeved between the two pulleys, a feeding rod is fixedly connected to a point on the belt, and the feeding rod is arranged perpendicular to the belt.

[0008] By adopting the above technical solution, the belt controls the feeding rod to move along the belt movement direction, so that the feeding rod contacts the to-be-formed carton at the bottom and feeds it out through the cavity.

[0009] The utility model is further configured as follows: a groove for the feeding rod to pass through is opened on the bottom plate of the material support frame, and the groove is arranged parallel to the belt.

[0010] By adopting the above technical solution, it is convenient for the feeding rod to pass through the groove to deliver the carton to be formed at the bottom.

[0011] The present invention is further configured such that the distance between the two pulleys is greater than the width of the material support frame.

[0012] By adopting the above technical solution, the feeding rod can easily deliver the carton to be formed completely out of the receiving rack.

[0013] The present invention is further configured as follows: one of the pulleys is fixedly connected to the drive motor.

[0014] The present invention is further configured as follows: one end of the discharge plate close to the carton forming machine is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the frame, and both ends of the rotating shaft are fixedly connected to gears.

[0015] By adopting the above technical solution, the control gear drives the rotating shaft to rotate, thereby controlling the rotation of the discharge plate.

[0016] The utility model is further configured as follows: the flip assembly includes two horizontally arranged racks, the racks are meshed with gears, a connecting rod is fixedly connected between the two racks, the connecting rod is slidably connected to the frame, a first cylinder is fixedly connected inside the frame, the output end of the first cylinder is fixedly connected to the connecting rod, and the first cylinder and the connecting rod are vertically arranged.

[0017] By adopting the above technical solution, the first cylinder controls the movement of the connecting rod, thereby controlling the movement of the rack, and the movement of the rack drives the gear to rotate.

[0019] By adopting the above technical solution, after the carton to be formed is fed into the discharge plate, one end contacts the limit plate. When the gear rotates under the control of the flip assembly, the limit plate supports the carton to be formed and prevents it from falling off the discharge plate. In the process of the material-taking suction cup adsorbing the carton to be formed and feeding it into the carton forming machine, the bottom of the carton to be formed will compress the limit plate, causing the limit plate to move in the direction of the straight plate, so that the carton to be formed will fall off the limit plate. Then the limit plate is reset under the action of the spring, waiting for the next carton to be formed.

[0020] The present invention is further configured such that the cross-sectional size of the material support frame is the same as the area of the carton to be formed.

[0021] The utility model is further configured as follows: the carton forming machine is provided with a second cylinder for controlling the material taking suction cup to approach or move away from the material discharge plate.
