Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when performing double-coating on the board, it is necessary to complete the coating and curing of one side of the board before the coating and curing of the other side of the board can be carried out. Therefore, in the actual production process , which is equivalent to two complete single-side coating processes, which not only has low work efficiency and low output, but also increases energy consumption and production costs.

Embodiment Construction

[0059] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0060] The invention discloses a double-sided coating process and equipment for a metal coil, comprising the following process steps:

[0061] S1: Unwinding the metal coil, specifically unwinding the metal coil through the unwinding unit.

[0062] S2: Adjust the tension of the metal coil unwound in step S1 through the tension unit.

[0063] S3: Pre-storing the metal coils whose tension has been adjusted in step S2 through the vertical looper.

[0064] S4: Adjust the tension and correct the deviation of the metal coil sent out by the vertical looper in step S3 through the tension unit with the deviation correction device.

[0065] S5: Perform double-sided spray cleaning on the metal coil that has undergone deviation correction and tension adjustment in step S4.

[0066] S6: Drying both sides of the metal coil that has been sprayed on both sides in step S5. ...

Abstract

The invention relates to a double-sided coating technology and device for a metal coil, and belongs to the technical field of metal packaging coating technologies. The technology comprises the following steps of S11: unreeling; S2: adjusting tension; S3: pre-storing; S4: performing tension adjustment and deviation rectification; S5: performing double-sided spray washing; S6: drying the two surfaces; S7: coating on two sides; S8: drying; S9: cooling; S10: adjusting tension; S11: pre-storing; and S12: rolling to obtain the metal coil with double-side coating. The technology has the effect of coating both sides of the metal coil simultaneously.

Description

technical field [0001] The invention relates to the technical field of metal packaging coating technology, in particular to a double-sided coating technology and equipment for metal coils. Background technique [0002] Printing graphics and text on metal sheets and making them into packaging containers is called printed iron cans, which is the most important part of the metal packaging industry. Metal packaging is an important part of China's packaging industry. Its output value accounts for a large proportion of the total output value of China's packaging industry. It mainly provides packaging services for industries such as food, beverages, oils, chemicals, pharmaceuticals, stationery and cosmetics. [0003] For example, the Chinese patent with the authorized announcement number CN104191845A discloses a production coating process and online processing device for three-piece pop can plates, including: substrate preparation, primer coating, baking curing, UV color printing, ...
