Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] Please see the appendix Figure 1 -Appendix Figure 4 This application proposes a packaging box feeding frame for an automatic box opener, comprising: a frame 100, the front opening of which is configured as a packaging box inlet; a door frame 200, rotatably connected to the packaging box inlet of the frame 100, wherein a guide plate 210 is provided on the side of the door frame 200 near the packaging box inlet, the door frame 200 is retracted into the packaging box inlet when lifted, and the door frame 200 is exposed from the packaging box inlet when pulled down; and a hook 300, which detachably hooks the upper beam of the frame 100 and the upper beam of the door frame 200 to keep the packaging box inlet in a closed state.

[0033] In this application, the frame 100 has a four-sided hollow structure, facilitating the installation of components such as cylinders and suction cups for adsorbing or pushing packaging boxes. The side of the door frame 200, near the bottom, is connected to the side beam of the frame 100 via a pivot. When the door frame 200 is raised, its bottom rotates around the pivot until the packaging box entrance is closed. When the entrance is closed, the guide plate 210 on the door frame 200 is hidden inside the frame 100, protected by the outward-facing side of the door frame 200. Due to the concealing function of the frame 100, the door frame 200 does not protrude when not in use, saving space and protecting the door frame structure. When the door frame 200 is pulled down, its bottom rotates in the opposite direction around the pivot until the packaging box entrance is opened, making operation convenient and quick. Since the hook 300 is movable, after removing the hook 300 from the frame 100, the door frame 200 can be pulled down to open the entrance of the packaging box. The hook 300 ensures the fixation of the door frame 200 on the frame 100 and is also easy to disassemble and assemble.

[0034] In order to enable temporary storage of the hook after the entrance of the packaging box is opened, this application also includes a hook 220, which is set at the upper beam of the door frame 200. When the door frame 200 is pulled down, the hook 300 can hook the hook 220.

[0035] In some implementations, the hook 220 is secured by nailing it into the door frame 200, or by threading the hook into the door frame 200. The hook 300 is temporarily suspended from the hook 220.

[0036] To further facilitate the detachable connection between the hook 300 and the nail, this application also includes a hole 310 provided on the hook 300, through which the nail 220 can pass. By fitting the hook 300 through the hole 310 onto the nail 220, the risk of the hook 300 falling off is reduced.

[0037] In one specific embodiment, please refer to the appendix. Figure 3 The hook 300 includes: a bottom edge 300a and a top edge 300c, which are arranged parallel to each other; a side edge 300b, which is vertically connected between one end of the bottom edge 300a and one end of the top edge 300c; and a hook protrusion 300d, which is located at the other end of the top edge 300c and protrudes towards the bottom edge 300a.

[0038] Due to the parallel arrangement of the bottom edge 300a and the top edge 300c of the hook, there is a certain suspension distance between them. This suspension distance should be greater than the sum of the thickness of the upper beam of the frame 100 and the thickness of the upper beam of the door frame 200, ensuring that the hook 300 extends into the door frame 200 from one side until the hook protrusion 300d crosses the upper beam of the frame 100. The hook 300 is then released, and the hook 300 moves downward slightly under its own weight until the top edge 300c of the hook rests on the upper beam of the frame 100. The hook protrusion 300d and the hook side edge 300b are used to restrict the downward movement of the door frame 200.

[0039] In this embodiment, in order to increase the structural strength of the hook 300 when it is suspended at the nail 220, the width of the bottom edge 300a of the hook is greater than the width of the top edge 300c of the hook, and the hole 310 is provided on the bottom edge 300a of the hook.

[0040] Additionally, please see the appendix. Figure 4 This application also includes a support 400 for limiting the downward pull of the door frame 200.

[0041] In order to completely avoid part of the rotational stroke of the door frame 200 and avoid motion interference, the support member 400 of this application is hinged to the lower beam of the frame 100 through the hinge support 500.

[0042] In one embodiment, the support member 400 includes: a first straight rod 400a, one end of which is rotatably connected to the hinge support 500, the rotation center line of the first straight rod 400a being perpendicular to the rotation center line of the door frame 200; a second straight rod 400b, which is perpendicularly connected to the other end of the first straight rod 400a; and a diagonal rod 400c, which is connected to the other end of the second straight rod 400b, the diagonal rod 400c making an angle α with the horizontal direction.

[0043] The first straight rod 400a rotates against the bottom surface of the hinge support 500, reducing the pressure at the junction of the first straight rod 400a and the hinge support 500. The second straight rod 400b reduces the distance between the diagonal rod 400c and the door frame 200. After pulling down the door frame 200, the diagonal rod 400c is rotated to the vertical plane. The angle α between the diagonal rod 400c and the horizontal direction is the final angle between the door frame 200 and the horizontal plane. That is, the smaller α is, the greater the pull-down range of the door frame 200 and the greater the opening degree of the packaging box entrance.

[0044] Preferably, α is between 30° and 45°. The larger α is, the greater the inclination of the door frame 200, and the easier it is for the packaging box on the guide plate 210 to tip over. The smaller α is, the smaller the inclination of the door frame 200, and the less likely the packaging box on the guide plate 210 will fall into the door frame 200 by its own weight. Therefore, a pushing force is required to achieve this, which can easily increase the equipment cost.

[0045] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
