PLC-based automatic aluminum foil welding device

Abstract

The invention discloses a PLC-based automatic aluminum foil welding device comprising a PLC system provided with a button. The PLC system is connected to a connecting welding machine movable motor, and a welding machine movable limit switch is mounted above a welding machine rail where the welding machine movable motor located; the PLC system is connected to a welding machine lifting oil cylinder; the welding machine is provided with a lifting oil cylinder limit switch; the PLC system is connected to a welding head motor, and a welding head motor limit switch is mounted on the side of a push plate of the inner side of a welding head; the PLC system is further connected to a welding head stretching cylinder; the welding machine movable limit switch, the lifting oil cylinder limit switch and the welding head motor limit switch are connected to the PLC system. Thus, automatic welding can be started through the button after belt breaking, signals of limit switches are transmitted to the plc, and the plc receives the limitations before executing the corresponded actions to implement the automatic vertical movement and welding; resource waste is reduced greatly, cost is reduced, and human resource can be saved well.

Description

technical field [0001] The invention relates to a welding device for broken strips of aluminum foil, in particular to a PLC-based automatic welding device for aluminum foil. Background technique [0002] Today, with the rapid development of industry, high efficiency and energy saving have become an indispensable part; while in the vertical slitting machine, there will be a lot of wasted resources when the finished products are spun out. These resources are returned to the furnace and recast , Reproduction can produce finished products, especially in the equipment of aluminum foil coiling, it is easy to break the tape due to improper operation or some accidental factors. In order to reduce unnecessary waste of resources after the tape is broken, in order to avoid these repeated work, in A welding machine that can move laterally relative to the aluminum strip is installed above the guide roller (where the strip is broken), and the welding head is installed on the welding m...

[0002] Today, with the rapid development of industry, high efficiency and energy saving have become an indispensable part; while in the vertical slitting machine, there will be a lot of wasted resources when the finished products are spun out. These resources are returned to the furnace and recast , Reproduction can produce finished products, especially in the equipment of aluminum foil coiling, it is easy to break the tape due to improper operation or some accidental factors. In order to reduce unnecessary waste of resources after the tape is broken, in order to avoid these repeated work, in A welding machine that can move laterally relative to the aluminum strip is installed above the guide roller (where the strip is broken), and the welding head is installed on the welding machine, and the welding machine is started by a button for welding; this not only greatly controls the waste of resources, but also improves the efficiency. There is also a significant improvement; but the welding machine of the traditional structure, the movement of the welding machine, the lifting of the welding machine, and the expansion and contraction of the welding head need to be controlled by their own control buttons, which makes the control unreliable and low in efficiency. Can't control costs well
