Servo transmission upper air suction conveying mechanism of printing paper feeding part

Abstract

The invention relates to the technical field of mechanical paper feeding mechanisms of corrugated cartons, in particular to a servo transmission upper air suction conveying mechanism of a printing paper feeding part. According to the servo transmission upper air suction conveying mechanism of the printing paper feeding part, paperboards can be accurately conveyed, the surfaces and the internal structures of the paperboards cannot be extruded or deformed, meanwhile, dust on the surfaces of the paperboards can be conveniently and fully cleaned, and the subsequent printing quality is guaranteed. The servo transmission upper air suction conveying mechanism of the printing paper feeding part comprises a rack, a lower air suction servo front edge paper feeding mechanism, an upper air suction conveying mechanism and a dust removal mechanism, wherein the lower air suction servo front edge paper feeding mechanism, the upper air suction conveying mechanism and the dust removal mechanism are installed on the rack; the upper air suction conveying mechanism is located at the output end of the lower air suction servo front edge paper feeding mechanism and comprises an adsorption air bellow, a connecting pipeline and an adsorption fan; a cavity is formed in the adsorption air bellow; an adsorption opening is formed in the bottom of the adsorption air bellow; multiple sets of idler wheels are installed at the adsorption opening; the dust removal mechanism is located below the upper air suction conveying mechanism and comprises a dust removal air knife; and the output end of the dust removal air knife inclines towards the paper feeding direction.

Description

technical field [0001] The invention relates to the technical field of corrugated carton mechanical paper feeding mechanism, in particular to a suction conveying mechanism of a printing paper feeding part driven by a servo drive. Background technique [0002] The printing machine is mainly composed of paper feeding part, printing part, slotting part and die cutting part. The corrugated cardboard raw materials are continuously and accurately conveyed to the printing section through the paper feeding section to print the surface of the cardboard. Then through the slotting part and die-cutting part at the back, the trimming and grooving of the carton are completed. [0003] At present, there are several ways of paper feeding and conveying in printing machines: 1. It consists of an upper paper feeding rubber shaft (the surface of the roller is made of rubber material) and a lower supporting paper shaft (the surface of the steel roller is textured). When feeding the paper board,...

[0003] At present, there are several ways of paper feeding and conveying in printing machines: 1. It consists of an upper paper feeding rubber shaft (the surface of the roller is made of rubber material) and a lower supporting paper shaft (the surface of the steel roller is textured). When feeding the paper board, the rubber and steel rollers are rotating. , contact the surface of the cardboard to generate friction to transport the cardboard, which reduces the thickness of the cardboard, thereby reducing the pressure resistance of the formed carton; 2. It consists of an upper paper feeding shaft (steel roller) and a lower supporting paper shaft (the surface of the steel roller). When feeding the cardboard, the steel roller and the steel roller are rotating, contacting the surface of the cardboard to generate friction to convey the cardboard, which reduces the thickness of the cardboard, thereby reducing the pressure resistance of the formed carton; The rotation of the wheel conveys the cardboard raw materials, but the downward suction conveying method cannot effectively clean the dust on the surface of the cardboard raw materials, which affects the quality of subsequent printing
