[0002] Sheet-fed offset press is an important part of printing machinery industry, and the development of its paper collecting structure parts is closely related to the efficiency and quality of the whole printing process. As the last unit of the printing machine, the main function of the paper collecting part is to receive the printed matter from the impression cylinder and send it to the paper collecting table by using the conveying structure. In order to send the printed matter to the paper collecting table, chain conveying structure is commonly used in the sheet-fed offset press. In the chain conveying structure, the paper collecting chain is arranged in the guide rail with the paper collecting nip. The layout design of the guide rail has a great influence on the improvement of printing quality and printing speed. Therefore, the reasonable layout of the paper collecting chain guide rail is very important for the design of the printing machine.

[0003] The existing outward protruding guide rail for printing machine paper collecting has certain disadvantages in use. First, the wallboard installed with the guide rail has a space of 80mm in the thickest part. Second, the connection between the guide rail and the wallboard is not directly connected by screws, but connected by forty or so pins and brackets. The pins and brackets are first installed on the wallboard, and then the guide rail is installed on the end face of the pins or brackets by screws. The contact area is small, and there are disadvantages such as insufficient rigidity, loud noise, and large guide rail wear. Therefore, we propose a guide rail structure for sheet-fed offset press. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a guide rail structure for sheet-fed offset press. By setting the wallboard body, a plurality of large planes for installing the guide rail structure are directly reserved when the wallboard body is erected, replacing the original small brackets, so that the two wallboard bodies are more convenient and faster when installing the guide rail structure, and the axial difference problem between the corresponding installation parts of the two wallboard bodies is successfully avoided. At the same time, the contact area between the wallboard body and the guide rail structure becomes larger, and the guide rail structure is more tightly and firmly installed after installation, so that the machine runs more smoothly. The end face can be matched with the installation end face of the guide rail structure, which enhances the rigidity and strength. When the machine is running, the noise is small, the vibration is small, and the transmission chain runs smoothly.

[0005] The above technical purpose of the utility model is realized by the following technical scheme:

[0006] A guide rail structure for sheet-fed offset press, comprising a wallboard body, the inner side of the wallboard body is provided with a large plane, and the outer end of the large plane is provided with an outward protruding guide rail.

[0008] Further, the inner end of the outer convex guide rail is threadedly connected with a screw.

[0009] By installing the screw, the installation and maintenance cost is preferably reduced.

[0010] Further, the screw is connected with the wallboard body through the large plane.

[0011] By installing the large plane, the cooperation between the wallboard body and the guide rail structure is more stable.

[0012] Further, the outer convex guide rail and the large plane are in contact connection.
