Description

TECHNICAL FIELD

[0001] The utility model relates to a can making technical field, especially a kind of metal can magnetic suction stand can device. BACKGROUND

[0002] In the automatic production process of metal can, especially tinplate empty can, there is a key posture conversion requirement between the welding of can body and subsequent processing procedures, and the stand can machine is the core equipment to realize this conversion, and its performance directly determines the operation efficiency of the whole production line, product quality stability and comprehensive production cost.

[0003] Specifically, the can body of tinplate empty can is usually formed by coiling and welding process, and the can body needs to be placed in a horizontal state (i.e., the axis of the can body is parallel to the horizontal plane) during welding. However, the can body after welding needs to enter subsequent processing procedures such as can cover assembly, leak detection, and spraying, which all require the can body to be in a vertical state (i.e., the axis of the can body is perpendicular to the horizontal plane). Therefore, the can body in a horizontal posture must be accurately and efficiently converted to a vertical posture by the stand can machine to ensure the continuous connection of the production process.

[0004] Currently, the common stand can machine in the industry is a V-shaped stand can machine, which has a simple structure. However, when the speed is high, the impact is large, which can easily scratch the can mouth. Moreover, when the can body is long, the can cannot be stably turned over, causing the can body to fall over and affecting production efficiency. UTILITY MODEL CONTENTS
