For the needs of subsequent production, the profiles need to be manually moved to the material frame in groups of one or several side by side and placed neatly, and the adjacent groups are staggered a certain distance. Since the workpiece is long (greater than 500mm), it is easy to collide and damage the product during the handling process when there is only one person. In this case, two people are required to work together, one at each end, which greatly wastes the labor and physical strength of the workers, is not efficient, and is prone to accidents.

In order to ensure that the V-shaped groove 2 can drive the turntable 37 to rotate easily, the structure of the turntable 37 is hollow; the first side and the second side of the V-shaped groove 2 are both perpendicular to the transmission direction of the conveyor belt 1.

[0033] When there are at least two material dividing mechanisms, the central axes of adjacent turntables 37 are fixed by couplings to ensure that the positions of the material dividing mechanisms relative to the conveyor belt 1 are consistent, so that the length direction of the metal profile can be kept perpendicular to the conveyor belt 1 during the conveying process and the material dividing process; the top of the first side of the V-shaped groove 2 extends out of the working surface of the conveyor belt 1, and the second side is flush with the working surface of the conveyor belt 1; the conveying direction of the conveyor belt 1 is from the second side of the V-shaped groove 2 to the first side; the distance from the first side to the second side of the conveyor belt 1 is consistent with the size of the profile of each group that needs to be divided in this direction; in order to be able to change the angle between the two ends of the V-shaped groove 2, the distance from the first side to the second side of the V-shaped groove 2 is adjusted, and the bottom of the first side of the V-shaped groove 2 is fixed to the automatic return component 3 through the adjustment component 4.

When the external force is eliminated, the ruler spring 34 drives the reset gear column 32 to rotate forwardly under its own action and drives the sector gear column 31 to move in the opposite direction; when the profile moves from the conveyor belt 1, it can press the top of the first side of the V-shaped groove 2, thereby driving the reset gear to rotate forward (shown as counterclockwise rotation in the figure). At this time, the second side of the V-shaped groove 2 extends out of the surface of the conveyor belt 1 and separates the profiles of the previous group from the profiles of the next group; when the tail of the profile of the current group is completely separated from the top of the first side of the V-shaped groove 2, the external force disappears, and the ruler spring 34 drives the V-shaped groove 2 to reset, so that the second side of the V-shaped groove 2 shrinks again to be flush with the working surface of the conveyor belt 1.

[0035] In order to avoid the gap between two adjacent groups of undivided profiles being too small, which would result in the second side of the V-shaped groove 2 being unable to be inserted, the top cross-section of the second side of the V-shaped groove 2 is conical, and a rubber stopper wheel 21 is provided on the side opposite to the first side; a plurality of pressure wheels 22 distributed up and down are provided on the top of the first side of the V-shaped groove 2; the axial length of the pressure wheel 22 is equal to or slightly smaller than the length of the first side of the V-shaped groove 2 in the conveying direction perpendicular to the conveyor belt 1.

[0036] The adjusting assembly 4 includes a fixed column 41, a rotating ring 42, and a locking pin 43; the fixed column 41 is welded to the end face of the turntable 37 and is consistent with the axial direction of the end face; the outer periphery of the rotating ring 42 is fixedly connected to the bottom of the first side of the V-shaped groove 2; one axial end of the rotating ring 42 has internal teeth, and the other end has a through hole 421 through which the locking pin 43 can pass; one axial end of the fixed column 41 is provided with external teeth meshing with the internal teeth, and the other end is provided with a plurality of limiting holes 411; the plurality of limiting holes 411 are evenly distributed around the fixed column 41; the rotating ring 42 and the fixed column 41 are sleeved together, and the internal teeth and the external teeth are meshing; the locking pin 43 can pass through the through hole 421 and be inserted into the limiting hole 411; when the locking pin 43 is inserted into the limiting hole 411, the rotating ring 42 and the fixed column 41 can be locked so that the two cannot rotate relative to each other; in order to facilitate the adjustment of the adjustment component 4, a stopper 44 is fixed to the end of the locking pin 43 located outside the rotating ring 42; a limit spring 45 is fixed between the stopper 44 and the outer peripheral surface of the rotating ring 42 and is sleeved on the outer periphery of the locking pin 43. The stopper 44 is pulled outward to make the limit pin move away from the limiting hole 411, so that the relative rotation between the rotating ring 42 and the fixed column 41 can be realized. After releasing the hand, the limit pin is inserted into the limiting hole 411 under the elastic force of the limit spring 45 itself, thereby completing the locking, and the operation is simple.

[0037] In order to prevent dust, the sector gear column 31 and the reset gear column 32 are both rotatably fixed to the cover body 5 by bearings or the like; the top of the cover body 5 is provided with a through groove that enables the V-shaped groove 2 to rotate; one of the side surfaces of the cover body 5 is flush with the end surface of the annular box body 33; the bottom of the cover body 5 is fixed with retractable legs 6 and movable rollers; thereby facilitating the movement of the material dispensing mechanism.

[0038] The working process of the present invention is as follows: the material distribution mechanism is placed between two adjacent conveyor belts 1, and the first side of the V-shaped groove 2 is kept at the conveying front side of the second side. The central axes of the turntables 37 of the plurality of material distribution mechanisms are fixedly connected through a coupling; at the same time, the stoppers 44 at the two end surfaces of the turntable 37 are pulled to make the locking pin 43 away from the limiting hole 411, and the stoppers 44 are released after the first side of the V-shaped groove 2 is rotated to the required position. Under the action of the reset spring, the locking pin 43 passes through the penetration hole 421 and is inserted into the limiting hole 411;

[0039] Start the conveyor belt 1, and the two adjacent groups of profiles move closely from the starting position of the conveyor belt 1 to the second side of the V-shaped groove 2; when the front group of profiles reaches the first side of the V-shaped groove 2, under the power drive of the conveyor belt 1 and the gravity of the profiles themselves, the profiles overcome the resistance of the ruler spring 34 and press the pressure wheel 22 located on the first side of the V-shaped groove 2, so that the V-shaped groove 2 drives the turntable 37 and the fan gear column 31 to rotate forward, and the second side of the V-shaped groove 2 swings with the turntable 37, and its top extends out of the working surface of the conveyor belt 1, so that the blocking wheel 21 suppresses the movement of the next group of profiles; after the front group of profiles completely passes through the first side of the V-shaped groove 2, the ruler spring 34 relies on its own elastic force to drive the reset gear column 32 to rotate forward, and drives the fan gear column 31 to rotate in the opposite direction, so that the V-shaped groove 2 is reset, and the blocking wheel 21 shrinks below the working surface of the conveyor belt 1, so that the next group of profiles is transmitted forward.
