Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] refer to figure 1 and figure 2, is a conveying device for an offset printing machine disclosed in the present invention, comprising a frame 1 arranged on the ground, a conveying frame 2 fixedly disposed on the frame 1, a conveyor belt 3 surrounding the conveying frame 2, and the conveyor belt 3 The paper can be driven to be conveyed forward along the surface of the transmission frame 2. The frame 1 is rotatably connected to the limit mechanism 4. The limit mechanism 4 includes a turret 5 that is rotatably connected to the transmission frame 2 through a rotating shaft. The turret 5 is arranged in a square frame shape. The frame 5 is slidably connected with a correction mechanism 6 for correcting the position of the cardboard on the conveying frame 2. The turret 5 is also provided with a wind pressure assembly 7 that prevents the edges of both sides of...

Abstract

The invention discloses an offset printer conveying device capable of decreasing the rejection rate, relates to the field of printing equipment, and aims at increasing the finished product rate of traditional printing. According to the technical scheme, the offset printer conveying device capable of decreasing the rejection rate is characterized in that the offset printer conveying device comprises a rack, a conveying frame arranged on the rack and conveying belts arranged on the conveying frame in a surrounding manner; a limiting mechanism is rotatably connected to the rack and comprises a rotating frame rotatably connected to the conveying frame, the rotating frame is shaped like a square frame, a correcting mechanism used for conducting position correcting on paper boards on the conveying frame is slidably connected to the rotating frame, and an air pressure assembly used for preventing two side edges of the paper boards from being warped upwards is arranged on the rotating frame; and the conveying frame is provided with a control assembly used for controlling the rotating angle of the rotating frame. The offset printer conveying device capable of decreasing the rejection rate has the advantages that the paper positions can be corrected, and the finished product rate can be increased.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a conveying device of an offset printing machine which reduces the reject rate. Background technique [0002] In the printing industry, the printing of cardboard has changed from traditional printing to automated printing. Among them, the offset printing machine is a kind of flat printing machine. When printing, the printed graphics and texts are first printed from the printing plate to the rubber cylinder, and then transferred to the paper by the rubber cylinder. [0003] Existing offset printing machines usually include feeding mechanism, conveying mechanism, printing mechanism, curing mechanism and unloading mechanism. When the paper is transferred from the feeding mechanism to the conveying Skew will greatly affect the printing uniformity in subsequent printing steps, thereby reducing the printing yield. Contents of the invention [0004] Aiming at the deficien...
