Description

Technical Field

[0001] The utility model relates to the technical field of paper feeding devices, and particularly relates to a continuous paper feeding device for a printing machine. Background Technique

[0002] When a printing machine is working, a paper feeding device is required to transport raw materials. The paper feeding device usually uses a negative pressure suction cup to adsorb the paper and move it to a conveyor for transporting the paper.

[0003] As described in a paper feeding device of a printing machine (authorization publication number: CN 212221820 U) disclosed in the prior art, "The utility model discloses a paper feeding device of a printing machine, which relates to the field of printing machines and includes a bottom plate. A support plate is provided at the top end of the bottom plate. An air injection pipe is provided inside the support plate. An ion rod is installed inside the air injection pipe. An air outlet is provided on one side of the air injection pipe. A cross beam is provided at the top end of the support plate. A plurality of motors are installed at the top end of the cross beam, and the output end of the motor penetrates through the cross beam and extends to the bottom end of the cross beam to be connected with a rubber roller. Through the arranged central plate, extension plate, protruding pieces, and a plurality of suction cups, when the paper is separated and folded and floated by the wind to reach below the suction cup, the negative pressure pipe is opened to form a negative pressure inside the negative pressure pipe. The negative pressure reaches the suction cup through a rubber pipe, so that a negative pressure is formed inside the suction cup, thereby adsorbing the paper at the bottom end of the suction cup. The plurality of suction cups can adsorb the paper at multiple points, increasing the force-bearing area of the paper and reducing the pressure in a local area of the paper to protect the paper."

[0004] Regarding the above description, the applicant believes that there are the following problems:

[0005] During the use of this utility model, the paper is transported to directly below the suction cup by starting the support cylinder. One side of a plurality of papers is attached to the rubber roller. When paper feeding is required, first start a plurality of motors. The output ends of the plurality of motors drive the plurality of rubber rollers to rotate in opposite directions. In the actual use process, since this device relies on a paper feeding roller for transmission during use, and during the stacking process of the paper, it is manually placed by staff, it is easy to deviate. At the same time, the position of the suction cup of this device is fixed, resulting in the inability to use papers of different sizes well during transportation. Therefore, it is necessary to improve a continuous paper feeding device for a printing machine to solve the above problems. Content of the Utility Model
