Description

Technical Field

[0001] The present application relates to the field of carton printing, and in particular to a carton printing machine. Background Art

[0002] Carton printing machine is a printing device that can print the required text, pattern and other information on the surface of the carton. It generally includes the process of inking, embossing, paper feeding, etc. Carton printing generally includes single printing, printing slotting / die-cutting, gluing and linkage production line.

[0003] At present, after the cardboard is processed by the printing press, the cardboard is slotted to facilitate the forming of the carton. However, after the cardboard is slotted, some strips of paper scraps usually stick to the cardboard, and the paper scraps need to be removed before the carton is formed to avoid affecting the forming of the carton. Therefore, in order to remove the paper scraps on the cardboard after the slotting, a fan is usually set at the place where the cardboard is discharged to blow air onto the cardboard, and the wind blown by the fan blows the paper scraps off the cardboard.

[0004] Because the same printing press usually processes different sizes of cardboards, and the slot positions on different sizes of cardboards are also different, it is necessary to adjust the angle between the fan and the cardboard so that the wind blown by the fan can be aimed at the paper scraps at the slot position, so as to clean up the paper scraps. However, the fan is usually fixedly installed at the outlet of the printing press. When the position of the slot on the cardboard changes, the wind blown by the fan cannot be aimed at the slot position of the cardboard, resulting in poor cleaning effect of the paper scraps on the cardboard.

[0059] Reference Fig.10 and Fig.11 When the locking member is working, the unlocking rod 441 slides in the unlocking groove, so that the positioning groove on the unlocking rod 441 is aligned with the locking rod 446, and the locking rod 446 is inserted into the positioning groove driven by the locking spring 445, thereby positioning the unlocking rod 441, so that the control rod 4315 remains in the lifted state. When the push rod 447 is pushed upward, the push rod 447 drives the locking rod 446 to move upward and press the locking spring 445, so that the locking rod 446 is separated from the unlocking rod 441, and then the rotating sleeve 417 drives the control rod 4315 downward under the action of the compression spring 416, so that the transmission worm wheel 4314 on the control rod 4315 is meshed with the transmission worm 4312 again, and the unlocking rod 441 slides in the unlocking groove in the direction away from the deflection groove 414. Then, the push rod 447 is released, so that the locking rod 446 contacts the side wall of the unlocking rod 441 under the action of the spring.

[0060] The working principle of the embodiment of the present application is as follows: cardboard is fed into the chassis 1 for processing, and the processed cardboard is transported to the conveyor belt 23 for transportation. When the cardboard passes under the guide nozzle 33, the wind blown out by the fan 31 is guided to the grooved part on the cardboard through the guide nozzle 33, so that the paper scraps on the cardboard are blown away from the cardboard, thereby achieving the effect of cleaning the cardboard.

[0061] When the thickness of the cardboard being processed changes, the driving handle 436 is controlled to rotate, thereby controlling the lifting driving member to work, so as to adjust the height of the support frame 411. At the same time, when the support frame 411 is lifted and lowered, the angle driving member drives the angle adjustment component 42 to work, so that the angle adjustment component 42 controls the air guide cover 32 to rotate around the support frame 411, thereby adjusting the angle between the fan 31 and the cardboard, so that the wind blown by the fan 31 passes through the air guide nozzle 33 and blows toward the cardboard, so that the wind blown by the fan 31 blows toward the grooved part on the cardboard, so as to improve the cleaning effect of paper scraps.

[0062] When the angle between the fan 31 and the paperboard needs to be fine-tuned, the unlocking member is controlled to work, thereby controlling the unlocking sleeve 444 to lift the control rod 4315, so that the transmission worm wheel 4314 on the control rod 4315 is separated from the transmission worm 4312, and the unlocking rod 441 is positioned by the locking member, so that the control rod 4315 remains in the lifted state. Then, the control handle 4316 is driven to rotate, thereby realizing the operation of the angle adjustment component 42, thereby adjusting the angle between the fan 31 and the paperboard, so that the paper scraps at different positions on the paperboard can be cleaned.

[0063] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
