[0033] The working process of an automatic aluminum profile straightening machine is:

[0034] Profile alignment separation device such as Figure 1 As shown, the profile 2 is stored on the cooling bed platform 3. The cooling bed platform 3 driving motor Ⅰ13 drives the felt synchronous belt Ⅰ10 to convey the profile 2 to the stop roller 16 of the stop device 4. The travel switch Ⅰ15 installed on the stop device 4 can detect whether the material is in place. The basis for judging whether the material is in place is that the travel switch Ⅰ15 receives a signal of the material being in place when half or more of the number of stop rollers 16 within the full length of the profile 2. The stop device 4 is normally in the raised state (such as Figure 4 As shown in the figure, after the material is in place, the felt synchronous belt Ⅰ10 of the cooling bed platform 3 stops moving. When the material-in-place signal fed back by the profile switch Ⅰ15 and the stop signal of the cooling bed platform 3 drive motor Ⅰ13 are obtained at the same time, the material blocking device 4 retracts and the proximity switch Ⅰ is triggered. When the profile 2 is aligned, it will touch the multiple travel switches Ⅱ21 installed on the detection device 1 (as shown in the figure). Figure 2As shown in the figure, the position of the material head can be determined according to the number of travel switches II21 triggered after the profile 2 is aligned, and then the distance required for the main stretching to be stretched can be determined. After the control system of the straightening machine 6 receives the signal, the main stretching is automatically adjusted to a suitable clamping position. The detection device 1 and the material blocking roller 16 are raised and lowered at the same time, and the alignment of the profile 2 and the material head detection are completed at the same time. The application of the travel switch can effectively detect special-shaped profiles, increase the applicable range and detection accuracy of the profile 2 section for aligning and detecting the material head.

[0035] After the stopper 4 is retracted, the felt synchronous belt Ⅰ10 of the cooling bed platform 3 starts to transport the profile 2. After the profile 2 is aligned, it is continuously transported to the bridge device 5 by the cooling bed platform 3. When the travel switch Ⅲ7 on the bridge device 5 detects the signal of the profile 2, the cooling bed platform 3 drive motor Ⅰ13 reverses, driving the profile 2 on the cooling bed platform 3 to retreat to the front of the stopper 4. The stopper 4 rises to prepare for the alignment of the next profile 2, realizing the fully automatic separation of the profile 2 and the detection of the material head position.

[0036] The felt synchronous belt II 26 of the bridge device 5 and the felt belt of the feeding robot of the straightening machine 6 start to rotate at the same time, and the two ends of the profile 2 are transported into the jaws of the straightening machine 6. When the profile 2 reaches the center of the jaws of the straightening machine 2, it will contact the material blocking roller of the feeding robot, so that the axis of the profile 2 is located in the clamping area (such as Figure 7 The photoelectric switch above the jaws detects that the profile 2 is in place, the bridge device 5 and the feeding robot stop rotating at the same time, the robot stop roller retracts, and the straightening machine 6 starts to straighten and correct the profile 2.
