[0002] During the production process of existing disposable coffee cup lids, a circle of grooves needs to be processed on the side of the cup lid. The groove structure is concave toward the inner side of the cup lid and is used to cooperate with the opening at the upper end of the cup body, so that the cup lid can be buckled more firmly on the upper end of the cup body through this circle of groove structure.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

The cup lid positioning and rotating drive mechanism 2 includes a cup lid positioning mold 2-4 and a rolling drive device 2-2 for driving the cup lid positioning mold 2-4 to rotate. The cup lid 5 is placed on the cup lid positioning mold 2-4; the pressing mechanism 3 is located above the rolling drive mechanism and is used to press the cup lid 5 onto the cup lid positioning mold 2-4; the rolling wheel mechanism 4 includes a side shift component, on which is provided a rolling wheel mounting frame 4-5, on which is rotatably connected a rolling wheel 4-6; the side shift component is also provided with a rolling wheel 4-6 rotation drive device for driving the rolling wheel 4-6 to rotate, and the rolling wheel 4-6 rotation drive device is transmission-connected to the rolling wheel 4-6; the rolling wheel 4-6 is driven horizontally by the side shift component.

[0027] In the present invention, the outer contour surface of the cup lid positioning mold 2-4 matches the cup lid 5, so that the cup lid 5 can be placed on the cup lid positioning mold 2-4 in a matching manner. When in use, the cup lid 5 to be rolled is placed on the cup lid positioning mold 2-4, and then a certain pressing force is applied to the upper part of the cup lid 5 by the pressing mechanism 3, so that the cup lid 5 is stably pressed on the cup lid positioning mold 2-4; then the side shift component drives the rolling wheel 4-6 to move horizontally, so that the outer edge of the rolling wheel 4-6 contacts the position on the cup lid 5 that needs to be rolled, and a certain top pressure is applied by the rolling wheel 4-6; then the cup lid positioning mold 2-4 is driven to rotate by the rolling drive device 2-2, and the cup lid 5 placed on the cup lid positioning mold 2-4 rotates synchronously; at the same time, the rolling wheel 4-6 rotates to drive the device The rolling wheel 4-6 is driven to rotate, and the rotational angular velocity of the rolling wheel 4-6 rotation driving device is consistent with the rotational angular velocity of the rolling driving device 2-2, and the two rotate in opposite directions. The side of the cup cover 5 is rolled by the rotation of the rolling wheel 4-6, thereby forming a groove structure on the side of the cup cover 5; after the rolling is completed, the rolling wheel 4-6 rotation driving device and the rolling driving device 2-2 both stop running, the side shift component drives the rolling wheel 4-6 to reset, the clamping mechanism 3 is reset, and the operator removes the cup cover 5 from the cup cover positioning mold 2-4; then the rolling process of the next cup cover 5 is carried out in the same way.

[0028] Among them, the cup cover positioning and rotating drive mechanism 2 also includes a mounting frame 2-1, the mounting frame 2-1 is fixedly connected to the frame 1, the rolling drive device 2-2 is arranged on the mounting frame 2-1, the rolling drive device 2-2 is provided with a rotating shaft 2-3, and the cup cover positioning mold 2-4 is arranged at the upper end of the rotating shaft 2-3.

[0029] Specifically, the mounting frame 2-1 includes a lower end plate 2-1b, an upper end plate 2-1a, and a connecting column 2-1c. The upper end plate 2-1a and the lower end plate 2-1b are fixedly connected to the connecting column 2-1c, and the connecting column 2-1c is fixedly connected to the frame 1. The rolling drive device 2-2 is fixedly connected to the upper end plate 2-1a.

[0030] Furthermore, the cup cover positioning rotation drive mechanism 2 also includes a demolding component, which includes a demolding plate 2-13 and a demolding drive 2-7 for driving the demolding plate 2-13 to move up and down. The demolding plate 2-13 is annular and is located on the periphery of the cup cover positioning mold; the cup cover 5 on the cup cover positioning mold 2-4 is lifted up by the upward movement of the demolding plate 2-13.

[0031] During the rolling process of the cup cover 5, the pressing mechanism 3 applies a downward pressing force to the cup cover 5. After the process is completed, a certain bonding force is generated between the cup cover 5 and the outer surface of the cup cover positioning mold 2-4, which causes certain troubles in removing the cup cover 5 after the process is completed. In the utility model, by adding a demolding component, during demolding, the demolding plate 2-13 is driven upward by the demolding driving member 2-7. During the upward movement, the demolding plate 2-13 supports the lower end of the cup cover 5 and lifts it up, thereby separating the cup cover 5 from the cup cover positioning mold 2-4, making it easier for the operator to remove the cup cover 5.

[0032] In this embodiment, the demoulding drive member 2-7 adopts a cylinder, and the rolling drive device 2-2 adopts a servo motor.

[0033] The demolding drive member 2-7 is connected to the mounting frame 2-1. A lower movable plate 2-8 is connected to the demolding drive member 2-7. The lower movable plate 2-8 is provided with a first guide rod 2-9, which slides with the mounting frame 2-1. An upper movable plate 2-11 is provided at the upper end of the first guide rod 2-9.

[0034] A demoulding drive member mounting seat 2-6 is provided on the lower side of the lower end plate 2-1b, and the demoulding drive member 2-7 is mounted on the demoulding drive member mounting seat 2-6.

[0035] The clamping mechanism 3 includes a fixed seat 3-1, a lifting component 3-3, and a pressing die 3-6.

[0036] The lifting member 3-3 is driven up and down by the lifting drive member 3-2, thereby driving the pressing die 3-6 to move up and down. During the rolling process of the cup cover 5, the pressing die 3-6 will press the cup cover 5, and the cup cover 5 will rotate. The rotational cooperation between the pressing die 3-6 and the lifting member 3-3 ensures the rotation of the pressing die 3-6, so that the cup cover 5 can be stably pressed during the rotation process.

The cooperation between the second guide rod 3-4 and the second guide sleeve 3-5 realizes the guidance of the lifting member 3-3.

[0038] The side shifting assembly includes a base plate 4-1 and a movable base 4-4. The base plate 4-1 is provided with a guide rail 4-3, to which the movable base 4-4 is slidably connected. The base plate 4-1 is also provided with a side shifting driver 4-2, which is connected to the movable base 4-4 and drives the movable base 4-4 to move horizontally. The rotation drive device for the rolling wheel 4-6 and the rolling wheel mounting frame 4-5 are both mounted on the movable base 4-4. The side shifting driver 4-2 drives the movable base 4-4 along the guide rail 4-3, thereby achieving contact or separation between the rolling wheel 4-6 and the cup lid 5.

[0039] The rolling wheel 4-6 rotation driving device is a servo motor, and the rolling wheel 4-6 rotation driving device is connected to the rolling wheel 4-6 through a transmission belt 4-8. In this embodiment, the side shift driving member 4-2 is a cylinder.

[0040] The present invention has the following advantages: the present invention is easy to operate and improves the efficiency of the rolling process of the cup cover 5. In the process of rolling the cup cover 5, the rolling wheels 4-6 and the cup cover 5 are actively rotated, and the rotational angular velocity of the two is consistent. There is no speed difference at the contact position between the rolling wheels 4-6 and the cup cover 5, which reduces local wear on the surface of the cup cover 5 and improves the quality of the rolling process.
