[0037] The anti-deviating sawing machine material feeding device of the present invention has the following working principle:

[0038] First, place the device at a position where the sawing machine needs to be fed, and then adjust the height of the overall support frame 3 by adjusting the anchor screws of the anchor 2 to be suitable for sawing machines of different models and heights;

[0039] Second, the profile to be processed is placed on the rolling shaft 10, and then the jacking cylinder 62 is controlled to start to move. Under the action of the jacking cylinder 62, the locking wheel frame 63 is moved horizontally on the slide rail through the slider 65, so that the locking wheel 64 presses the profile on the first driving wheel 77 and the second driving wheel 78 of the driving wheel assembly 7, and then the clamping cylinder 82 is controlled to start to move. Under the action of the clamping cylinder 82, the cover frame 83 is longitudinally shifted inside the gantry 81 through the shift block 85, so that the height position of the clamping wheel 84 is adjusted to be pressed above the profile, and then the profile is wrapped around the rolling shaft 10, the first driving wheel 77 and the second driving wheel 78, the locking wheel 64, and the clamping wheel 84, so as to prevent the profile on the rolling shaft 10 from tilting upward due to the downward pressure when the profile is cut;

[0040] Third, control and start the drive motor 93 so that the first pulley 94 drives the pull rope 95 to move. The pull rope 95 forms two extension lines at the left and right sides of the first pulley 94. The extension line at the left end passes through the lower side of the outer surface of the second pulley 96 and the upper left side of the third pulley 97 and is installed on the right side of the front part of the support frame 99. The extension line at the right end passes through the right side of the outer surface of the fourth pulley 98 and is installed on the left side of the front part of the support frame 99. Under the positive and negative rotation of the first pulley 94, the support frame 99 is driven to move horizontally above the horizontal frame 92, so as to change the horizontal extension position of the support frame 99 according to the position of the sawing machine, so that the support frame 99 moves to the bottom of the saw blade close to the sawing machine, and plays a supporting role on the bottom side of the profile when the profile is cut.

[0041] Fourth, when sawing the profile, the stepper motor 73 is controlled to start, and the stepper motor 73 drives the first gear 74 to rotate. The rotation of the first gear 74 causes the second gear 75 to drive the third gear 76 to mesh and rotate, so that the first gear 74 drives the first driving wheel 77 to rotate inside the driving wheel frame 71, and the third gear 76 drives the second driving wheel 78 to rotate inside the driving wheel frame 71. Under the rotation of the first driving wheel 77 and the second driving wheel 78, the profile is driven to move horizontally under the limit of the rolling shaft 10, the locking wheel 64 and the clamping wheel 84, so as to push the profile to move below the saw blade of the sawing machine, and the profile is further supported by the support plate frame 99;

[0042] Fifth, the sawing machine is controlled to start to saw the profile. During the sawing process of the profile, the servo motor 43 can be controlled to start. Under the action of the servo motor 43, the two rollers rotate synchronously to drive the screw 413 in the first adjustment structure 41 and the second adjustment structure 42 to rotate on the inner side of the bearing block 412. Under the cooperation of the screw 413 and the arc-shaped tooth block 414, the slide 415 is moved forward and backward on the arc-shaped groove frame 416 in an arc-shaped trajectory, thereby driving the support frame 3 to move and adjust the position in an arc-shaped trajectory to change the angle between the profile and the sawing machine, avoid the sawing machine blade from entering the profile too much and causing excessive friction between the blade and the profile to wear the blade, thereby increasing the service life of the sawing machine blade and ensuring the sawing effect of the profile.
