Description

Technical Field

[0001] The utility model relates to the technical field of cardboard processing, in particular to a cardboard printing and conveying structure. Background Art

[0002] A cardboard printing machine is a printing device that can print required words, patterns and other information on the surface of cardboard. It generally includes process flows such as plate mounting, inking, imprinting and paper feeding. Among them, a transmission structure is required when conveying cardboard. The transmission structure includes a frame and a conveyor belt arranged on the frame. The printing machine is arranged above the frame. During use, the cardboard is placed on the conveyor belt, and the conveyor belt drives the cardboard to move into the printing machine. The printing machine prints on the surface of the cardboard. However, the cardboard may shift during the conveying process, affecting the printing quality. Moreover, the existing transmission structure cannot flatten the slight warping on the cardboard, which will also affect the subsequent printing quality of the cardboard. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a cardboard printing and conveying structure aiming at the above defects, which can not only correct the position of the cardboard during the transmission process, but also press and flatten the slight warping on the cardboard to avoid affecting the printing quality of the cardboard.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a cardboard printing and conveying structure, including a conveying component. The conveying component includes a frame and a conveyor belt arranged on the frame. A first deviation correction component is arranged on the frame. The first deviation correction component includes first push plates respectively arranged on both sides of the frame and a first air cylinder for driving the first push plates to move horizontally. One side of each of the two first push plates extends into the printing machine. Pressing components for pressing the cardboard are respectively arranged on both sides of the frame.

[0005] Compared with the prior art, the beneficial effect of this solution is that after the cardboard processed in the previous process is placed at the input end of the conveyor belt, the conveyor belt drives the cardboard to move. When the cardboard moves into the range of the first push plates, the two first air cylinders respectively drive the two first push plates to move towards each other until the inner sides of the two first push plates respectively contact both sides of the cardboard, correcting the deviation of the cardboard so that it is in the middle position on the conveyor belt. One end of the first push plate extends into the printing machine, and the first push plate continuously limits the cardboard to prevent it from shifting again during the journey from the conveyor belt into the printing machine. While correcting the cardboard through the first deviation correction component, the pressing components press the surface of the cardboard to flatten the slight warping on the cardboard to avoid affecting the printing quality of the cardboard.

[0006] As a preferred embodiment of the present utility model, the pressing assembly includes a connecting block, a connecting rod disposed on the connecting block, and a roller disposed at one end of the connecting rod. The roller is located above the conveyor belt, and the connecting block is detachably connected to the first push plate.

[0007] Beneficial effects of this solution: Since the connecting block is installed on the first push plate, the roller can move along with the movement of the first push plate, and the cardboard can be flattened according to the specific size of the cardboard, with a wide range of adaptability. Moreover, the connecting block is detachably connected to the first push plate, which is convenient for disassembly and assembly.

[0008] As a preferred embodiment of the present utility model, chutes are provided on the upper sides of both of the first push plates along their lengths, and the connecting block is slidably engaged with the chutes.

[0009] Beneficial effects of this solution: By slidably engaging the connecting block in the pressing assembly with the chutes on the first push plate, the pressing assembly is detachably connected to the first push plate, which is not only convenient for adjusting the position of the pressing assembly on the first push plate, but also convenient for disassembling and assembling it for replacement and other treatments.

[0010] As a preferred embodiment of the present utility model, a plurality of first connection holes are provided on the side walls of the chutes along their lengths, and a second connection hole is provided on the connecting block. The pressing assembly is fixed to the first push plate by a locking member passing through the first connection hole and the second connection hole.

[0011] Beneficial effects of this solution: After installing the connecting block on the first push plate and adjusting the position of the pressing assembly according to the specific size of the cardboard, the pressing assembly is fixed to the first push plate by a locking member passing through the first connection hole and the second connection hole, preventing the pressing assembly from moving along with the movement of the cardboard during the flattening process of the cardboard and affecting the pressing effect.

[0012] As a preferred embodiment of the present utility model, a fan is provided above one end of the frame away from the first deviation rectifying assembly.

[0013] Beneficial effects of this solution: After the cardboard is printed by the printing machine, it is conveyed out of the printing machine through the conveyor belt. Since the ink on the surface of the printed cardboard may not be fully dried, the fan provided above the frame is used to assist in air-drying the cardboard after it is removed from the printing machine, preventing the printed surface on the upper side of the cardboard from becoming smeared during subsequent processing and affecting the quality of the cardboard.

[0014] As a preferred embodiment of the present utility model, a second deviation rectifying assembly is provided at one end of the frame where the fan is provided. The second deviation rectifying assembly includes second push plates respectively provided on both sides of the frame and a second air cylinder for driving the second push plates to move horizontally.

[0015] Advantages of this solution: After the cardboard is conveyed out of the printing machine, the second cylinders located on both sides of the frame drive the two second push plates to move relatively until the inner sides of the two second push plates are respectively in contact with both sides of the cardboard, thereby correcting and positioning the cardboard and preventing the cardboard from shifting under the blowing of the fan.
