Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Refer to Figure 1This utility model provides an embodiment of a continuous paper feeding device for a paper cup machine, including a workbench 1. A paper feeder 2 is fixedly connected to the upper surface of the workbench 1. A limit rod group 3 is fixedly connected inside the paper feeder 2. Paper sheets can be placed into the limit rod group 3 for limiting, facilitating the paper feeding component to complete paper feeding and material picking from below the paper feeder 2. A stacking rack 4 is fixedly connected to the right side of the upper surface of the workbench 1. Multiple stacked paper stacks can be placed in a linear array in the left-right direction inside the stacking rack 4. The device, in conjunction with the component on the left side, can then process the individual stacks of paper. When the paper is picked up, a set of overhead rods 5 is fixedly connected to the left side surface of the stacking rack 4. The upper end of the set of overhead rods 5 is at the same level as the inner bottom surface of the stacking rack 4. When the paper stack inside the stacking rack 4 is pushed to the left, the leftmost paper stack will be pushed onto the set of overhead rods 5. The set of overhead rods 5 consists of three fixed rods. When the paper stack moves above the set of overhead rods 5, the bottom will be suspended. Side plates are fixedly connected to the front and rear sides of the upper surface of the stacking rack 4. The side plates can limit the pushing and moving of the paper stack, so that the paper stack maintains vertical movement in the left and right directions.

[0031] Reference Figure 1 - Figure 3 The stacking rack 4 is equipped with a pushing unit, which includes a chute 41. The chute 41 is located on the bottom surface of the stacking rack 4. A lead screw 42 is rotatably connected to the inner front wall of the chute 41. A motor 43 is fixedly connected to the right side surface of the stacking rack 4. The left output end of the motor 43 passes through the stacking rack 4 and is fixedly connected to the right end of the lead screw 42. When the motor 43 starts, it can drive the lead screw 42 to rotate. A T-shaped push plate 44 is threadedly connected to the outer side of the lead screw 42. When 42 rotates, it can move the T-shaped push plate 44 synchronously. The bottom of the T-shaped push plate 44 is slidably connected to the inside of the slide groove 41. The slide groove 41 can guide and limit the movement of the T-shaped push plate 44, so that the T-shaped push plate 44 can only move in a straight line in the left and right direction. When the motor 43 starts and drives the lead screw 42 to rotate, it can drive the T-shaped push plate 44 to move in a straight line in the left and right direction under the limit of the slide groove 41. When the T-shaped push plate 44 moves to the left, it can push the stack of paper placed inside the stacking rack 4.
