Description

Technical Field

[0001] The utility model relates to the technical field of carton printing, in particular to a pneumatic transmission device for paper feeding of a printing machine. Background Technique

[0002] A printing machine mainly consists of a paper feeding part, a printing part, a slotting part, and a die-cutting part. The corrugated cardboard raw material is continuously and accurately conveyed to the printing part through the paper feeding part for printing on the surface of the cardboard. Then, through the subsequent slotting part and die-cutting part, the trimming and slotting forming of the carton are completed.

[0003] The main working steps of the existing paper feeding part: First, place the cardboard on the transportation table, then start the fan and the rotating wheel. When the fan starts, it generates negative pressure to press the cardboard tightly against the rotating wheel, and then the cardboard is transported to the printing part by the rotation of the rotating wheel.

[0004] In the process of paper feeding by the traditional printing machine paper feeding device, there may be problems such as the cardboard being offset in position when entering the paper feeding part, the cardboard may be stuck during transportation, and the printing position of the cardboard may be offset when entering the printing part. At this time, the machine needs to be stopped, and then the cardboard needs to be replaced or straightened manually, which will greatly reduce the work efficiency. Therefore, a pneumatic transmission device for paper feeding of a printing machine that can prevent the cardboard from being offset is needed. Content of the Utility Model

Specific implementation manner

[0030] In order to facilitate the solution of problems, the embodiment of the present utility model provides a pneumatic transmission device for efficient paper feeding of a printing machine. The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1-3 , this embodiment provides a pneumatic transmission device for efficient paper feeding of a printing machine, including,

[0032] A transport mechanism 200, with a printer 100 provided at the transport end, and the transport end is the end where the cardboard enters the printer 100; the transport mechanism 200 includes a transport table 203, which is provided with a blower inside, and a number of adsorption holes 202 are evenly arranged at the top of the transport table 203 and communicate with the outside and the inner cavity of the transport table 203; when the blower operates, negative pressure is generated, and the cardboard is adsorbed through the adsorption holes 202; a number of rotating wheels 201 are evenly arranged at the top of the transport table 203. When the cardboard is placed on the transport table 203, the rotating wheels 201 rotate to transport the cardboard. This part is used to transport the cardboard and transport the cardboard into the printer 100 for printing; specifically: when the cardboard enters from the initial end of the transport table 203, the blower is started to adsorb the cardboard on the rotating wheels 201, and then the rotating wheels 201 are started to drive the cardboard to move until the cardboard is sent into the printer 100.

[0033] Furthermore, the contact surface between the rotating wheel 201 and the cardboard is made of rubber to increase the friction between the cardboard and the rotating wheel 201, prevent the cardboard from shifting again during transportation, and affect the paper feeding rate. At the same time, the rubber material is relatively soft to prevent the excessive adsorption force of the blower from causing the cardboard to be squeezed between the rotating wheel 201, deforming the cardboard, and rendering the cardboard unusable.

[0034] The clamping mechanism 300 for clamping the cardboard is symmetrically arranged at the top of the transportation mechanism 200 and is used to straighten the cardboard to prevent the cardboard from shifting in position, which may cause the printing to shift. The clamping mechanism 300 includes an electric push rod 301 arranged at the initial end of the transportation of the transportation mechanism 200. One end of the electric push rod 301 is fixed to the top of the transportation mechanism 200, and the other end is provided with a clamping plate 302. The initial end of the transportation of the transportation mechanism 200 is the end where the cardboard enters. Fixed plates 303 are symmetrically arranged at the top of the transportation mechanism 200. When the cardboard enters from the initial end of the transportation of the transportation mechanism 200, the electric push rod 301 is activated to drive the clamping plate 302 to move, clamp and straighten the cardboard, prevent the cardboard from getting stuck during transportation due to its position shift, which affects the transportation of the subsequent cardboard, and prevent the cardboard from entering the printer 100 in a shifted state, causing the position of the pattern or text printed on the cardboard to shift, resulting in the cardboard being unusable and wasted. After being straightened, the cardboard continues to be transported, and the fixed plates 303 on both sides can prevent the cardboard from shifting again during transportation.

[0035] Furthermore, a rubber layer is provided on the clamping surface of the clamping plate 302 to prevent the electric push rod 301 from applying excessive force when clamping the cardboard, damaging the cardboard and rendering it unusable, thus causing waste.

[0036] A cleaning mechanism 400 for cleaning the transport mechanism 200 is connected to the transport mechanism 200. The cleaning mechanism 400 includes a slide rail 401 fixed to one side of the transport mechanism 200, a moving block 402 slidably connected to the slide rail 401, and the moving block 402 can move along the slide rail 401; one end of an electric telescopic rod 403 is arranged at the top of the moving block 402, and a connecting block 404 is provided at the other end; a connecting rod 405 is L-shaped, one end is connected to the connecting block 404, and a cleaning brush 406 is provided at the other end. When the electric telescopic rod 403 expands and contracts, the lifting of the cleaning brush 406 can be controlled through the connecting block 404 and the connecting rod 405. When this part is in use, the electric telescopic rod 403 is activated, thereby driving the connecting block 404, the connecting rod 405, and the cleaning brush 406 to move, so that the cleaning brush 406 contacts the transport surface of the transport table 203, and then the moving block 402 drives the electric telescopic rod 403, the connecting block 404, the connecting rod 405, and the cleaning brush 406 to move along the slide rail 401, thereby realizing the cleaning of the transport surface of the transport table 203, preventing dust and garbage accumulated during the long-term transportation of cardboard from blocking the adsorption holes 202, thereby reducing the adsorption force on the cardboard and causing the cardboard to shift during transportation, affecting the paper feeding efficiency.

[0037] During use:

[0038] The cardboard enters through the initial end of the transport table 203. The electric push rod 301 is activated to drive the clamping plate 302 to move and clamp and straighten the cardboard; then the fan is activated to adsorb the cardboard on the rotating wheel 201. The rotating wheel 302 is activated to start transporting the cardboard. During transportation, with the assistance of the fixed plates 303 on both sides, the cardboard enters the printer 100 for printing in the correct position. When cleaning the transport surface of the transport table 203, the electric telescopic rod 403 is activated to drive the cleaning brush 406 to descend until it contacts the transport table 203, and then the moving block 402 starts to move along the slide rail 401, so that the cleaning brush 406 moves and cleans on the transport table 203.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
