Integrated screen printing device for tinplates and screen printing technology

Abstract

The invention discloses an integrated screen printing device for tinplates. The integrated screen printing device comprises the tinplates, a feeding assembly, a screen printing assembly, a transportation assembly, a first UV drying and curing machine, an infrared heating and drying machine, a second UV drying and curing machine and a discharging assembly. The invention further discloses a screen printing technology of the integrated screen printing device for the tinplates. According to the device and the technology, four attraction guns are changed into two attraction guns currently, the twoattraction guns are adjusted to be in an electromagnetic attraction mode, and meanwhile, relatively soft flannelette coats the ends, to be in contact with the tinplates, of the attraction guns, so that the problems of scratching or attraction gun marking and the like on the surfaces of the tinplates caused in the processes of attracting and supplying a part of the tinplates with surfaces coated with films are prevented from generating; the speed of a transmission belt is adjusted, a deceleration belt is arranged by taking the phenomenon that the tinplates do not slip after deceleration as thestandard, a section of differential belt is additionally arranged, and a deceleration sliding block is additionally arranged so that the tinplates can be conveyed to a drying room without collision damage, the product quality is effectively improved, and the rejection rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of tinplate screen printing technology, and in particular relates to a tinplate integrated screen printing device and a screen printing process. Background technique [0002] Tinplate packaging has a wide coverage in the packaging container industry due to its good airtightness, preservation, light protection, sturdiness and unique metal decoration charm, and it is a commonly used packaging variety in the world. With the continuous enrichment of various CC materials, DR materials, and chrome-plated iron for tinplate, the development of packaging products and technologies has been promoted, and tinplate packaging is full of innovations everywhere. Because of its strong oxidation resistance, various styles and exquisite printing, tinplate packaging containers are popular among customers, and are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, ind...

AI Technical Summary

Problems solved by technology

[0003] There are the following problems in the prior art tinplate screen printing process: 1. The tinplate is heavy, and some product surfaces are covered with film, and its surface is soft and easy to scratch. The existing equipment is that four suction guns suck the iron at the feeding table position After the material is transported to the conveyor belt, it is very easy to cause problems such as scratches on the surface of the tinplate and suction gun marks during the feeding process; 2. When the tinplate is transported from the head of the screen printing machine to the joint of the drying room, due to the transmission The speed is high, and the phenomenon of impact and damage to the tinplate is easy to occur during the transmission process; 3. Due to the heavy weight of the tinplate, in the process of final blanking, the front end of the tinplate transmission direction tends to fall first, which is different from the previously collected tinplate printing materials. Form scratches, which can easily cause scratches on the printing surface
