A positioning protrusion 11 is arranged on the outer wall of the cup mold 9 to position the rotation angle of the paper cup. The cup handle forming and conveying mechanism includes a cup handle conveying platform 6, a cup handle forming and punching module 5 and a bag handle clamping and conveying component. A cutting knife 7 is arranged at the discharge end of the bag handle conveying platform 6. The cutting knife 7 is arranged on a driving cylinder 8. By controlling the driving cylinder 8 to drive the cutting knife 7 to move, the cup handle can be cut. The bag handle clamping and conveying component includes a clamping claw, and the clamping claw is arranged on a moving seat 15. Specifically, the clamping claw includes an upper clamping claw 13 and a lower clamping claw 12. One end of the lower clamping claw 12 is hinged to the upper clamping claw 13, and the lower clamping claw 12 is hinged to a hinge seat 29. The hinge seat 29 is connected to a lifting cylinder 14. By controlling the lifting cylinder 14 to drive the lower clamping claw 12 to swing, the clamping and loosening of the cup handle can be achieved. The moving seat 15 can be reciprocated and arranged between the cup handle conveying platform 6 and the rotating frame 4.A hot ironing head 3 is arranged above each cup mold 9, and the hot ironing head 3 is connected to the lifting drive assembly. Specifically, the lifting drive assembly includes a guide seat 32 arranged around the rotating frame 4, and the height of the guide seat 32 changes along its surrounding path. The guide seat 32 has at least one end The lifting section with a gradually increasing height and a straight section with a horizontal height, the hot ironing head 3 is arranged on a lifting seat 30, and the lifting seat 30 is movably arranged on the rotating frame 4. The roller 31 at the bottom of the lifting seat 30 can be abutted against the top of the guide seat 32. As the rotating frame 4 moves The lifting seat 30 rotates, and the lifting seat 30 contacts the lifting section of the guide seat 32, and drives the hot ironing head 3 to rise, so that the hot ironing head 3 is away from the cup mold 9. Then the lifting seat 30 contacts and cooperates with the straight section of the guide seat 32, so as to put the paper cup on the cup mold 9 for positioning and rotation, and send the cup handle to the paper cup. When the cup mold 9 is already fitted with a paper cup, and the cup handle is just sent between the paper cup and the hot ironing head 3, the lifting seat 30 is separated from the guide seat 32, and the lifting seat 30 descends under the action of gravity, driving the hot ironing head 3 to descend, and welding the cup handle to the paper cup. A discharging mechanism is also provided on one side of the cup handle forming and conveying mechanism, and the discharging mechanism includes a discharging hook 18, one end of which is swingably provided on a movable seat 19 and is connected to a return spring or a torsion spring.

A groove 33 is provided on the side wall of the inner end of the cup mold 9 for the discharging hook 18 to be inserted into. A second slide seat 20 is provided on the movable seat 19, and the second slide seat 20 is connected to the second slide rail 21 on the frame to guide the movement of the movable seat 19, further improving the stability and reliability of its movement. When discharging, the movable seat 19 drives the discharging hook 18 to move toward the paper cup, and the discharging hook 18 contacts and squeezes the outer wall of the paper cup to swing outward and squeeze the reset spring. When the discharging hook 18 moves to the groove 33, the discharging hook 18 is stuck in the groove 33 under the action of the reset spring. At this time, the discharging hook 18 is just located at the cup mouth of the paper cup, and then the movable seat 19 drives the discharging hook 18 to move back, and the discharging hook 18 hooks the paper cup from the cup mold 9 to realize the discharging operation of the paper cup.

[0024] The working principle of the present invention is as follows: paper cups fall from the paper cup stacking rack 1 and are transported through the paper cup conveying path 2, so that the paper cups are put into the cup molds 9 on the rotating rack 4, and then the rotating rack 4 rotates to drive the paper cups to the paper cup positioning and rotating mechanism, and the moving rack 23 moves, driving the rotating pressure head 22 to approach the paper cups, and pressing the bottom of the paper cups between the rotating pressure head 22 and the rotating disk 10, at this time, the driving motor 25 drives the rotating pressure head 22 to rotate, and then synchronously drives the paper cups and the rotating disk 10 to rotate, because the cup mold 9 is provided with a positioning protrusion 11, and the inner wall of the paper cup will also have a convex rib during the welding process of the paper cup, as the paper cup rotates, when the convex rib of the inner wall of the paper cup hits the positioning protrusion 11, the paper cup will be positioned, so that the paper cup can be rotated to the required specified angle, and then the moving rack 23 It moves backward, driving the rotating pressure head 22 to separate from the paper cup, and the rotating frame 4 drives the paper cup to rotate to the cup handle forming and conveying mechanism. At the same time, the cup handle is conveyed on the cup handle conveying platform 6 and is punched and formed by the cup handle forming and cutting module 5. Then the cup handle is sent to the cutting knife 7 for cutting. At the same time, the moving seat 15 drives the clamping claw to move to the cup handle, and the clamping claw clamps the cut cup handle. Then the moving seat 15 drives the clamping claw and the cup handle to the top of the paper cup. At this time, the hot stamping head 3 descends to weld the cup handle to the paper cup. Then, as the rotating frame 4 rotates a certain angle, the hot stamping head 3 continues to press on the cup handle to ensure that the cup handle can be firmly welded to the paper cup. Finally, the rotating frame 4 drives the paper cup with the cup handle welded to the discharging mechanism, and the paper cup is hooked out of the cup mold 9 by the discharging hook 18 to realize the discharging operation of the paper cup.
