[0002] A three-dimensional packaging machine, also known as a three-dimensional packaging machine for transparent films, a cigarette packaging machine, a six-sided folding cold packaging machine for transparent films, a transparent film packaging machine, etc., is a medium packaging device that uses BOPP film or PVC as the packaging material to form a three-dimensional hexahedron folding and sealing package for the object to be packaged. The three-dimensional packaging machine for transparent films is widely used in the three-dimensional skin packaging of cosmetics, pharmaceuticals, foods, health care products, audio-visual products, stationery, daily necessities, and other products outside the box with transparent films.

[0003] The existing patent with the publication number CN208515851 U (hereinafter referred to as the existing patent) discloses a three-dimensional packaging machine for transparent films. The three-dimensional packaging machine has a simple structure, is practical and convenient, has a high degree of automation, can process paper boxes of different widths, and has a high production efficiency. Among them, the above-mentioned existing patent discloses that its carton feeding device includes a bracket, a driving roller, a conveyor belt, and a third motor. One end of the bracket is connected to the machine frame. The two ends of the driving roller are movably connected to the bracket. The driving roller is driven by the third motor to rotate on the bracket. The third motor is fixed on the bracket and is located on the side of the bracket. The upper surface of the bracket is also provided with a conveyor belt. The conveyor belt wraps the driving roller, so that the conveyor belt can be driven by the driving roller. The paper box is placed on the conveyor belt, and the conveyor belt conveys the paper box to the position of the box pushing device under the drive of the third motor.

[0004] However, the carton feeding device of the above-mentioned existing patent has the following technical problems: when the overall weight of the paper box is relatively light, the paper box is more likely to be affected by unstable factors such as the wind blown by a blower or a fan in the packaging workshop, resulting in problems such as left and right deviation of the conveying position of the paper box on the carton feeding device, which in turn affects the subsequent transparent film packaging effect of the paper box. Moreover, the carton feeding device of the above-mentioned existing patent does not disclose the relevant device structure for limiting the paper box on the conveyor belt, which is likely to cause the position deviation of the paper box conveyed by the carton feeding device.

Correspondingly, the vertical lead screw is rotatably arranged on the base, the sliding seat is threadedly connected with the vertical lead screw, the horizontal lead screw is rotatably arranged on the sliding seat, and the fixed seat is threadedly connected with the horizontal lead screw. By rotating the vertical lead screw to drive the sliding seat to move up and down, and by rotating the horizontal lead screw to drive the fixed seat to move left and right, the vertical position and the horizontal position of the first limiting rod can also be adjusted.

[0037] Preferably, shielding curtains are provided at the bottom ends of both the first limiting rod 251 and the second limiting rod 261. The shielding curtains can effectively reduce the attachment of external dust and the like to the paper box.
