Detailed implementation mode

[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present utility model is not limited thereto.

[0022] As Figures 1 to 3 shown, a cup lid top feeding mechanism for a cup lid forming machine in this embodiment includes a frame 1. A feeding table 2 is fixed on the top of the frame 1. A storage rack 3 for stacking cup lids is fixed above the feeding table 2. A material taking mechanism 4 for removing the cup lids and a pushing mechanism 5 for sending the removed cup lids to a top feeding mechanism 6 are arranged below the storage rack 3 on the feeding table 2;

[0023] The top of the storage rack 3 is provided with round holes, and four support rods 31 are circumferentially and evenly distributed inside the round holes. The four support rods 31 are round rods, and spiral bodies 32 for supporting the edges of the cup lids are arranged at the bottoms of the four support rods 31;

[0024] The material taking mechanism 4 includes four suction cups 41 arranged in a rectangular array. The bottoms of the suction cups 41 are connected to air pipes 42. The frame 1 is provided with a lifting cylinder 43 for driving the suction cups 41 to lift and lower. The inside of the air pipe 42 is in negative pressure;

[0025] The pushing mechanism 5 includes a chute 51 opened on the feeding table 1. A pushing plate 52 is arranged inside the chute 51. The frame 1 is provided with a pushing cylinder 53 for driving the pushing plate 52 to move;

[0026] The top feeding mechanism 6 includes a top feeding hole 61 arranged at the front end of the chute 51. A top feeding plate 62 is arranged directly below the top feeding hole 61. The frame 1 is provided with a top feeding cylinder 63 for driving the top feeding plate 62 to lift and lower;

[0027] A rotary disk 7 is also provided. Six to eight die pressing holes 71 are evenly distributed in a circle on the edge of the rotary disk 7. The die pressing holes 71 are aligned with the top feeding hole 61 after each intermittent rotation of the rotary disk 7.

[0028] During operation, stack the die-cut cup top covers and place them between the four support rods 31. The spiral body 32 supports the bottom edge of the stack of cup top covers from all around to prevent it from falling. The lifting cylinder 43 drives the four suction cups 41 to rise simultaneously and adhere to the lowermost cup top cover. When the suction cups 41 descend, the lowermost cup top cover can be sucked and dropped. After the cup top cover lands on the feeding table 2, the pushing cylinder 53 pushes the pushing plate 51 forward to push the dropped cup top cover to directly above the feeding hole 61. Then, the feeding plate 62 rises to push the cup top cover into the die-pressing hole 71. Since the diameter of the cup top cover is larger than that of the die-pressing hole 71 and the edge of the cup top cover is die-cut into a serrated shape, during the process of being pushed into the hole, the edge will fold downward. The feeding plate 62 continues to rise to embed the cup top cover with the folded edge into the annular cup cover body within the die-pressing hole 71.

[0029] To make the edge of the cup top cover fold better and be better embedded into the cup cover body, in this embodiment, the top edge of the feeding plate 62 is chamfered, and the angle of the chamfer relative to the axis is 5 - 10°.

[0030] When the pushing mechanism 5 pushes the cup top cover, to prevent the cup top cover from moving left and right, two side baffles 8 are symmetrically arranged on the feeding table 2 with respect to the sliding groove 51. To make the cup top cover exactly stop at the feeding hole 61 and facilitate adjustment, the feeding table 2 is provided with a limiting plate 9 connected by bolts to limit the forward sliding distance of the cup top cover, and the limiting plate 9 is arranged opposite to the feeding hole 61 with respect to the sliding groove 51.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention. For the convenience of describing the technical solutions, the front, back, left, right, up, middle, down, etc. orientations used are based on the drawings, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
