Improved feeding device of corrugated board printing press

Abstract

The invention discloses an improved feeding device of a corrugated board printing press. The improved feeding device of the corrugated board printing press comprises a material placement device and amaterial taking device arranged at the front end of the material placement device. The material placement device comprises a blocking mechanism, a placement platform, a stepping motor, a first threaded rod, a first sliding base, a push plate, a transverse sliding groove hole, a supporting brush, a discharging opening, two vertical sliding groove holes, two baffles, a second threaded rod, two second sliding bases and an auxiliary material push mechanism. A workbench of the placement platform is provided with the two vertical sliding groove holes and the transverse sliding groove hole located between the two vertical sliding groove holes. The first threaded rod, the stepping motor and the second threaded rod are arranged at the bottom of the workbench of the placement platform. A rotary shaft of the stepping motor is fixedly connected with the first threaded rod. The first threaded rod is sleeved with the first sliding base. The first threaded rod and the first sliding base are connectedthrough threads. The first sliding base is located in the transverse sliding groove hole. Compared with the prior art, the reliability of feeding can be improved, the rate of finished products of paperboard printed matter is improved, and the printing press is applicable to corrugated boards of various sizes, and the production efficiency is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of a corrugated cardboard printing machine, in particular to the technical field of an improved feeding device for a corrugated cardboard printing machine. 【Background technique】 [0002] At present, the printing industry is developing rapidly. In the printing industry, especially the color printing industry with high quality requirements, the requirements for cardboard are getting higher and higher. The cardboard should be avoided from being damaged during the transmission process, so as not to affect the printing effect of the cardboard. The existing printing machine adopts the paper-feeding method with the printing surface of the cardboard facing upwards. This paper-feeding method is easy to cause a large number of cardboards stacked on the top to scratch the printing surface of the bottom cardboard, and a large number of cardboards stacked on the top will cause scratches on the printing surface of the b...

[0002]At present, the printing industry is developing rapidly. In the printing industry, especially the color printing industry with high quality requirements, the requirements for cardboard are getting higher and higher. Should try to avoid being damaged, so as not to affect the printing effect of the cardboard

The existing printing machine adopts the paper-feeding method with the printing surface of the cardboard facing upwards. This paper-feeding method is easy to cause a large number of cardboards stacked on the top to scratch the printing surface of the bottom cardboard, and a large number of cardboards stacked on the top will cause scratches on the printing surface of the bottom cardboard. The lowermost cardboard produces greater pressure, which makes it difficult to send out the lowermost cardboard, which will easily lead to the scrapping of cardboard printed matter, especially the cardboard printed matter with poor surface wear resistance

As a result, the feeding reliability is poor and the yield of cardboard printed matter is reduced
