Square can-making production line

Abstract

The invention relates to a square can-making production line. The square can-making production line is provided with a rotary weld joint positioning station, a square expanding station, a printing station, a first flanging station, a bottom sealing station, a dust removal station, an overturning station, a second flanging station and a necking and can sealing station which are sequentially arranged. A rotary weld joint positioning mechanism is arranged on the rotary weld joint positioning station. A square expanding mechanism is arranged on the square expanding station. A printing mechanism isarranged on the printing station. Flanging mechanisms are arranged on the first flanging station and the second flanging station. A bottom sealing mechanism is arranged on the bottom sealing station.A dust removing mechanism is arranged on the dust removing station. An overturning mechanism is arranged on the overturning station. A necking and can sealing mechanism is arranged on the necking andcan sealing station. According to square can-making production line, an automatic reset function is added to the printing mechanism of square can-making, the structures of the flanging mechanisms aresimplified, the dust removal station is added, the prior square can production technological process is optimized, further automatic production and manufacturing are achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a production line for making square cans. Background technique [0002] In the production process of the existing square cans, a series of process production processes such as rotary welding seam positioning, square expansion, printing, flanging, bottom sealing, flipping, shrinking, and canning are required for the square cans. It needs manual assistance to carry, which has a low degree of automation and low production efficiency. At the same time, after the existing printing mechanism completes a printing operation on the opposite can, it cannot automatically reset, and the operation is inconvenient, which delays the production speed; the existing flanging equipment has complex structures, and generally has defects such as unstable flanging pressure, which affects the turning The quality of the side, sometimes even leads to product scrapping, and the production efficiency is low; there is no dust removal process in the existi...

[0002] In the production process of the existing square cans, a series of process production processes such as rotary welding seam positioning, square expansion, printing, flanging, bottom sealing, flipping, shrinking, and canning are required for the square cans. It needs manual assistance to carry, the degree of automation is low, and the production efficiency is low

At the same time, after the existing printing mechanism completes a printing operation on the opposite can, it cannot automatically reset, and the operation is inconvenient, which delays the production speed; the existing flanging equipment has complex structures, and generally has defects such as unstable flanging pressure, which affects the turning The quality of the side can sometimes even cause the product to be scrapped, and the production efficiency is low; there is no dust removal process in the existing can making production line, and dust is easy to accumulate inside the square can during the can making process, which affects the normal progress of the subsequent process
