Problems solved by technology

Therefore, the base material can only be completed through multiple production processes. Each process is independent of each other, which is time-consuming and labor-intensive. Moreover, the coating has to be baked at high temperature for many times, which reduces the performance of the coating film to a certain extent. How to optimize the three-piece The coating process of cans will become the main problem we are studying now

Embodiment 1

[0053] The present invention relates to a production and coating process for three-piece cans, which is used to produce a certain brand of functional beverage cans (250ml). The base material is tinplate, the hardness is T4, and the amount of tin plating is 1.1 / 2.8g / m 2 (ie inner surface 2.8g / m 2 , the outer surface is 1.1g / m 2 ), the tinplate specification is 0.20mm*858mm*1036mm, and its production process includes the following steps: tinplate preparation, primer coating, baking and curing, UV color printing, and a double-coating process. The double-coating process includes the following steps:

[0054] 1) Feeding: Place the color-printed iron stack (a stack of iron includes 1200 color-printed products) after UV color printing on the feeding power roller table of the coating machine, and pass the color-printed products through the rear-end suction nozzle on the feeding head. Separation, and then the color printing products are transferred to the conveying platform by the suc...

Embodiment 2

[0065] The production and coating process of the three-piece cans of the present invention is to produce a 113D aluminum cover of a beverage can, using an aluminum sheet with a thickness of 0.23 mm as the base material for production, and the production process includes the following steps: aluminum sheet preparation, UV color printing , also includes a double-coating process, the double-coating process includes the following steps:

[0066] 1) Feeding: Put the color-printed iron stack (a stack of iron includes 1400 color-printed products) after UV color printing on the feeding power roller table of the coating machine, and the color-printed products are passed through the rear end suction nozzle on the feeding head. The products are separated, and then the color printing products are transferred to the conveying platform by the suction nozzle at the front end of the feeding head;

[0067] 2) One-time positioning: the color printed product is sent to the first coating unit of ...

Abstract

The invention provides a production and coating technology and an online processing device of three plates for a zip-top can. The technology includes the steps of base material preparation, bottom coating, baking and solidification, UV color printing and a dual-coating technology. The dual-coating technology includes the following steps of (1) feeding, (2) primary positioning, (3) primary coating, (4) primary solidification, (5) discharging and conveying, (6) secondary positioning, (7) secondary coating, (8) online processing of skew color printing products, (9) final solidification and (10) stacking. By means of the production and coating technology, twice coating can be achieved continuously on line, and due to the fact that the production and coating technology is combined with an online coating film skew color printing product processing device organically, coating efficiency and quality of coating products can be greatly improved, the defective rate, energy consumption and risks existing in food security are reduced, energy is saved and environment is protected.

Description

technical field [0001] The invention relates to a metal packaging printing and coating technology, in particular to a production coating process and an on-line processing device of a three-piece pop-top can. Background technique [0002] With the continuous development of living standards and coatings industry, people's requirements for coatings for food packaging are increasing. The main base material of the three-piece can metal container is tinplate, which has good corrosion resistance, certain strength and hardness, good formability and easy welding, and the tin layer is non-toxic and tasteless, which can prevent iron from dissolving into the packaged material, and The surface is bright, and the printed picture can beautify the product. Therefore, it is widely used in food canning industry, chemical paint, oil, medicine and other packaging materials. When metal cans are used for food or beverages, organic protective coatings are usually applied to the inside of the met...
