Paper tube surface printing machine

Abstract

The invention discloses a paper tube surface printing machine which comprises a workbench, a plurality of supporting legs are fixedly connected to the bottom of the workbench, anti-skid bases are fixedly connected to the bottoms of the supporting legs, supporting plates are fixedly connected to the surface of the workbench, a pair of limiting mechanisms are rotationally arranged between the supporting plates, and telescopic frames are arranged on the outer sides of the supporting plates. The telescopic frames are fixedly connected to the surface of the workbench, and a printing roller is rotationally arranged between the telescopic frames. Compared with the prior art, the surface of an arc-shaped plate can be extruded through a paper tube, the arc-shaped plate can be deformed, and the tension of the arc-shaped plate on a reset spring is changed, so that a friction plate performs circular motion to a certain extent, the friction plate and the surface of an electrostatic roller can rub each other, and static electricity can be generated on the surface of the electrostatic roller; and dust, paper scraps and other impurities on the surface of a paper tube can be adsorbed, it is avoided that the impurities are accumulated on the surface of the ink discharging plate in the printing process, the situation of blank leaving in printing is reduced, and the printing quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of corrugated paper processing, in particular to a paper tube surface printing machine. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of cardboard paper. It has high mechanical strength and can withstand collisions and falls during handling. It is mainly used to make cartons and cartons. Sandwich and other packaging materials for fragile products. [0003] During the transportation process, because the cushioning performance and shockproof performance of the existing packaging boxes do not meet the requirements, when packing heavy items and fragile items such as porcelain, there are still a large number of gaps inside the corners of corrugated boxes, which requires stuffing More foam materials, so the shape of the corrugated box can be changed according to the weight of different shapes, and the product...

Problems solved by technology

[0003] During the transportation process, because the cushioning performance and shockproof performance of the existing packaging boxes do not meet the requirements, when packing heavy items and fragile items such as porcelain, there are still a large number of gaps inside the corners of the corrugated box, which requires stuffing More foam materials, so the shape of the corrugated box can be changed according to the weight of different shapes, and the production site is different according to the specifications. The cylindrical corrugated box tube can reduce the inner filling, but the surface printing of the cylindrical corrugated box is more difficult. , and the surface of the corrugated paper tube is in an uneven state due to material problems, which makes printing difficult. Therefore, we propose a paper tube surface printing machine to solve the above problems
