Logo printing device of paper tube for industrial explosive cartridge packaging

Abstract

The invention provides a logo printing device of a paper tube for industrial explosive cartridge packaging, relating to the production technology of a paper tube for industrial explosive cartridge packaging. The logo printing device structurally comprises an oscillation arm, an oscillation shaft, two oscillation rods, paper-feeding oscillation arms, a paper-feeding shaft and a paper-feeding rubber roll. The logo printing device is characterized in that the inner lateral surface of one paper-feeding oscillation arm of a paper-feeding mechanism is fixed with a container-shaped ink storage box with an inclined downward opening, a logo pattern is engraved on the roll surface of the paper-feeding rubber roll corresponding to the axial orientation of the ink storage box, a sponge structure is tightly sleeved in the cavity of the ink storage box, the lower end surface of the sponge structure and the roll surface of the paper-feeding rubber roll are in an abutting contact state, and an ink transfer pipe on the upper wall of the ink storage box is communicated with the opening of an inverted ink bottle fixed on the framework of the paper-feeding mechanism through a pipe joint and an ink supply hose. The invention has the following advantages: the existing paper tube machine can be used for logo printing after being reformed simply, the ink consumption is extremely low, and the comprehensive service cost is low. Besides, the produced industrial explosive product is easy to recognize and can be conveniently traced.

Description

Technical field: [0001] The invention relates to the production technology of a paper tube used for packaging industrial explosive rolls, in particular to the technology of printing and marking the paper tube. Background technique: [0002] At present, the industrial explosives packaged in small sizes are mainly Φ32mm and Φ35mm rolls, the length of which is 160mm-230mm, and most of the rolls are 35g / m. 2 ~45g / m 2 Paper tube packaging made of kraft paper. [0003] The kraft paper roll is carried out on the paper tube machine. The front paper feeding mechanism of the paper tube machine consists of a swing arm connected to the crank rod at the main shaft end of the roll roll, a swing shaft and a swing shaft that are dynamically fitted in the two shaft sleeves of the frame. Two swing rods fixed on the top, two slat-shaped paper-feeding swing arms hingedly connected to the lower end holes of the swing rods, paper-feeding shafts fixed in the holes at the other ends of the two pa...

Problems solved by technology

This method has the best marking effect, but it also has the following defects: First, when other companies in the industry do not make such a request, the cost of adding printing equipment for individual companies is too high for paper companies; After the packaging paper fails to pass the inspection and is returned, the packaging paper cannot be used for other purposes; the third is that the waste rate of packaging paper is high in the cutting and rolling process, and printing first and then rolling increases the cost of waste products

Based on the above reasons, the marking method of printing first and then rolling is not yet available in the current industrial explosives production industry.
