Detailed Description

In order that the objects and advantages of the invention will be more clearly understood, the following description is given in conjunction with the accompanying examples. It is to be understood that the following text is merely illustrative of one or more specific embodiments of the invention and does not strictly limit the scope of the invention as specifically claimed.

After the cutting device 500 finishes cutting, the aluminum tubes with fixed length are collected through the material collecting frame 600. Conventionally, after the previous roll of aluminum pipe is used up, the next roll of aluminum pipe needs to be re-distributed. As shown in fig. 1, the distance from the straightening device 400 to the cutting device 500 is conventionally that the aluminum pipe is manually pulled from the rack 200 to the cutting device 500, and during the period, the aluminum pipe needs to pass through a plurality of straightening rollers 410, because the aluminum pipe in the roll shape has a curvature, the aluminum pipe needs to be continuously aligned between the straightening rollers 410 by a manual operation so as to pass through the straightening rollers and be connected with the cutting device 500. Under the usual situation, the straightening device 400 comprises a plurality of straightening rollers 410, when the aluminum pipe is hard, the radian of the aluminum pipe can be straightened by the plurality of straightening rollers, so that the aluminum pipe with the radian is manually penetrated into the plurality of straightening rollers, the long time is usually spent, the labor is wasted, and the production efficiency is also influenced.
