[0038] The specific implementation process of the utility model device in the production process is as follows:

[0039] During production, adjust the spacing between the front feed guide frame 14 and the rear feed guide frame 13 and the front discharge guide frame 17 and the rear discharge guide frame 8 according to the specifications of the produced female bend pipe fittings 9, and then tighten the upper locking bolts with handles. Then adjust the angle of the overall fixing frame 23 of the direction adjustment mechanism relative to the product discharge conveyor 3 through the arc groove 29 on the top plate 28, and then adjust the front direction adjustment adjustable limit bracket 15 so that the front direction adjustment adjustable limit plate 16 will make the female bend pipe fittings 9 with female thread insert connection base 27 tightly against the direction adjustment belt 11, and then use the front adjustable limit guide bracket 20 and the rear adjustable limit guide bracket 7 to adjust the spacing between the front limit guide bar 19 and the rear limit guide bar 6, and finally start the device. At this time, the front-end unloading mechanism pours the female bend pipe fittings 9 into the centrifugal feeding conveyor 2 and conveys them out through the centrifugal feeding conveyor 2. Since the center of gravity of the female bend pipe fittings 9 is on the connecting base 27 with a female thread insert, the connecting base 27 with a female thread insert of the female bend pipe fittings conveyed from the centrifugal feeding conveyor 2 is located at the bottom. Due to the discharge port of the centrifugal feeding conveyor 2 and the guide limit of the front feed guide frame 14 and the rear feed guide frame 13, the all-plastic connector 26 of the female bend pipe fittings only has two directions: right or left (right is the product conveying direction). After the female bend pipe fittings 9 enter the product discharge conveyor 3, they are accelerated and driven by the conveyor belt on the product discharge conveyor 3 to be transported to the right, so that the spacing between each female bend pipe fitting can be stretched to ensure the stability of the orientation adjustment. In the process of the female bend pipe fittings being transported to the right, the orientation adjustment motor 22 uses the active pulley 21 and the driven tensioning pulley 25 to drive the orientation adjustment belt 11 to move to the left rear. Through the abutment of the front side orientation adjustment adjustable limit plate 16 and the friction of the orientation adjustment belt 11, the female bend pipe fittings rotate counterclockwise while being transported to the right, and finally the full plastic connector 26 of the female bend pipe fittings rotates counterclockwise. It bypasses the adjustable limit plate 16 for adjusting the orientation on the front side and sticks to the polytetrafluoroethylene limit block 10 for adjusting the orientation on the rear side in a unified posture facing right, and is driven by the product discharge conveyor 3 to be transported to the right, and then passes through the guidance and limitation of the front discharge guide frame 17 and the rear discharge guide frame 8 as well as the front limit guide bar 19 and the rear limit guide bar 6 to enter the laser marking conveyor 5 and is accelerated to the right by the laser marking conveyor 5 again to pull a distance between the female bend pipe products again to improve the stability of laser marking, and is finally marked with an anti-counterfeiting QR code at a fixed position by the laser marking machine 1, and then enters the next packaging equipment for packaging. The device continuously performs centrifugal material distribution and conveying of female bend pipes, limit-guided conveying, orientation adjustment, limit-guided conveying again, and finally laser marking, and repeats this process. The device is finished.

[0040] In addition, since the rear side orientation adjustment polytetrafluoroethylene limit block 10 and the orientation adjustment mechanism overall fixing frame 23 (i.e., the product conveying direction) are set at a predetermined angle, this design ensures that all products attached to the rear side orientation adjustment polytetrafluoroethylene limit block 10 after flipping and guiding are oriented in the direction of product conveying, which is convenient for subsequent laser marking, conveying and marking.

[0041] The advantages of the utility model are: novel design and reasonable conception. It mainly has the functions of centrifugal material distribution and transportation of female bent pipe fittings, then adjusting the direction to make them uniform, then limiting the guided transportation and finally performing laser marking. At the same time, it has a simple structure, saves costs, has minimal dependence on the environment, is easy to install and operate, and is easy to operate.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
