[0016] The U-shaped straw automatic packaging equipment of the present invention has a working principle as follows: the structure of the feeding mechanism 4 is the same as the structure in the Chinese utility model patent of "a U-shaped straw elbow forming device", the U-shaped straw is pulled by the positioning column in the conveying groove 4-1 and conveyed to the groove 1-3 below the first roller 1, with the rotation of the first roller 1, the U-shaped straw is conveyed to the second roller 2, at this time, the U-shaped end of the U-shaped straw is stuck in the groove 2-3-1 of the inner wheel of the second roller, and the long tube end is stuck in the groove 2-1-1 of the outer wheel of the second roller, with the rotation of the second roller 2, the U-shaped straw is transferred to the profiling groove 2 10-1 on the forming roller 10; at the same time, on the other hand, under the traction of the roller 17 The bottom film 15 is laid on the bottom surface of the forming roller 10 through the film feeding roller 11 through the tensioning action of the bottom film tensioning wheel 14. The profiling protrusion 11-1 cooperates with the profiling groove 10-1 to press the bottom film 15. The negative pressure of the pores 10-2 makes it difficult for the bottom film 15 to fall or swell. At the same time, the upper film 9 is laid on the forming roller 10 through the upper film tensioning wheel 6. As the forming roller 10 rotates, the U-shaped straw is wrapped by the bottom film and the upper film in the profiling groove 10-1 and is heated by the heating roller 7. After heating, the bottom film and the upper film are bonded together, and the U-shaped straw is sealed and wrapped to form a finished product 12. After passing through the first finished product tensioning roller 13 and the tensioning roller 16, the finished product is cooled and finally sent to the finished product blanking box.
