Description

Technical Field

[0001] The utility model belongs to the technical field of paper feeding of printing machines, and particularly relates to a paper loading mechanism of a printing machine. Background Technique

[0002] A web-fed printing machine is a printing machine that uses web paper as the printing material. The working principle of a web-fed printing machine mainly involves the transportation, printing, die-cutting, and waste treatment of web paper. Through an accurate control system, high-quality and high-efficiency printing operations can be achieved, enabling double-sided continuous and rapid printing, and can be connected to in-line cutting, folding, stacking and bundling, commercial advertising inserts, and distribution equipment to achieve high-efficiency printing operations.

[0003] Regarding the loading of printing machines, the existing publicly disclosed patent (publication number: CN 214827726 U) discloses a web-fed offset book printing machine that is convenient for loading, including a machine body. A rotating roller for placing web paper is rotated on the machine body. A loading device is arranged on one side of the machine body. The loading device includes a storage roller for placing multiple groups of web paper. The storage roller is coaxially connected to the rotating roller. The loading device further includes a push plate that abuts against the end face of the web paper. The push plate slides along the length direction of the storage roller. A driving component for driving the push plate to slide is arranged on the storage roller. The loading device further includes a supporting component for supporting the web paper. This application has the effect of being convenient for loading the printing machine and saving manpower.

[0004] The above loading mechanism lacks pre-treatment of the paper, resulting in more static electricity on the surface of the paper during the transportation and loading process, affecting subsequent printing. Therefore, we provide a paper loading mechanism for a printing machine to solve the above problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model provides a paper loading mechanism for a printing machine, including a supporting component for movably supporting a paper roll and a processing component for surface treatment of the paper roll. The supporting component includes a bottom frame, side plates fixed to the edge of the upper side of the bottom frame, a top plate fixed to the top of a support arm, a support arm movably arranged inside the upper part of the side plate, a shaft member fixed to the bottom of the support arm, a bracket fixed to the end of the support arm, an auxiliary roller movably arranged inside the bracket, and a pneumatic rod connecting the support arm and the side plate;

[0007] The processing component includes a thickness detection sensor fixed to one end of the top plate, a negative ion generator fixed to the other end of the top plate, a blower cooperating with the negative ion generator, and a power supply fixed to the upper side of the top plate.

[0008] The present utility model is further configured such that the power supply is connected to the fan, the negative ion generator, and the thickness detection sensor, and the thickness detection sensor is located directly above the paper roll.

[0011] The present utility model is further configured such that a connecting rod is fixed to the bottom of the side plate, and the side plates are parallel to each other.

[0012] The present utility model is further configured such that the base end of the air rod is movably connected to the side plate, and the telescopic end of the air rod is movably connected to the side of the support arm.

[0013] The present utility model has the following beneficial effects:

[0014] 1. The present utility model pre-treats the surface of the paper tape by setting a processing component to improve the subsequent printing quality. The thickness detection sensor is fixed at one end of the top plate and is located directly above the paper roll, and is used to detect the remaining amount of the paper roll for convenient replacement in a timely manner; the negative ion generator is fixed at the other end of the top plate and cooperates with the fan to generate negative ions for surface treatment of the paper tape, such as eliminating static electricity and reducing dust adsorption; the fan cooperates with the negative ion generator to blow the air flow containing negative ions onto the surface of the paper tape.

[0015] 2. The present utility model adjusts the height of the paper roll by setting the height of the adjusting support arm. The bracket is fixed at the end of the support arm, and an auxiliary roller is movably arranged inside for guiding the paper tape; the auxiliary rollers are arranged equidistantly inside the bracket and are matched with the paper tape output from the paper roll to ensure the stable transmission of the paper tape. With the above structural settings, the stable conveyance of the paper tape is realized, and the adjustment of the conveyance height and angle is relatively convenient.
