Description

Technical Field

[0001] This utility model relates to the field of cardboard box storage and transportation technology, and more specifically, to a cardboard box flipping device. Background Technology

[0002] In traditional cardboard box production, studs are fixed at the tail end of the box. When stacked, the protruding studs directly contact the bottom surface of the upper box, easily causing indentations or surface damage, affecting packaging integrity and transportation safety. Although manual flipping can adjust the stud position, it is inefficient and difficult to ensure consistency, especially in large-scale production, which can easily lead to secondary damage risks.

[0003] Existing equipment mainly focuses on the carton forming or stacking process and lacks a dedicated design for the flipping process. This results in the need for manual intervention or complex mechanical structures to adjust the position of the box staples. Some flipping devices have problems such as large positioning deviations and insufficient utilization of creases, making it difficult to ensure that the box staples are accurately transferred to the folded side joint. In addition, uneven stress on the carton in the traditional stacking process can easily cause structural deformation. Therefore, in order to address the above technical problems, a carton flipping device is proposed here. Utility Model Content

[0004] The purpose of this utility model is to provide a carton flipping device that automatically flips the carton by guiding it through creases and uses rotational thrust to transfer the box staples to the side joints, avoiding damage from protrusions during stacking. Combined with conveying positioning and flexible collection, it achieves efficient flipping, eliminates the manual adjustment process, ensures that the bottom surface of the carton is flat and free of indentations in multi-layer stacking, and improves storage and transportation safety.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention proposes a carton flipping device, which includes a device body 1. The device body 1 serves as the basic frame of the entire equipment and provides installation support for various functional components. A conveyor belt 2 is rotatably connected to the inner side of the device body 1. The conveyor belt 2 is the core component for carton conveying and realizes continuous transmission of carton through cyclical motion. A push plate 3 is fixedly connected to the outside of the conveyor belt 2. The push plate 3 plays the role of pushing and positioning the carton during the conveying process, ensuring that the carton maintains a stable posture during the conveying process.

[0026] A flipped carton 6 is placed on the upper side of the conveyor belt 2 between two sets of push plates 3. The flipped carton 6 is the object to be processed. The exterior of the flipped carton 6 has creases 7, which are pre-pressed fold lines that provide a guiding path for the subsequent flipping action. The end connection of the flipped carton 6 is riveted with a box nail 8. The box nail 8 is a technical challenge caused by the traditional carton sealing method, and its protruding characteristics directly affect the stacking quality. A baffle 5 is fixedly connected to the upper side of the end of the main body 1. The baffle 5 acts as a block and guide when the carton is conveyed to the end, prompting the carton to start flipping.

[0027] An auxiliary flipping mechanism is installed on the upper side of the main body 1 of the device. The auxiliary flipping mechanism installed on the upper side of the main body 1 is a key component for completing the flipping of the carton. The symmetrically arranged upright plates 9 provide a support base for the entire flipping mechanism. The second motor 10, which is fixed to the outside of the upright plates 9, serves as a power source. It drives the rotating shaft 11 to rotate the circularly arranged rotating plates 12. During the rotation, these rotating plates 12 apply a directional force to the surface of the carton to assist in completing the flipping action.

[0028] The mounting base 13 in the stacking mechanism serves as the installation base for the collection system. Its design, which is flush with the upper surface of the device body 1, ensures smooth transition of the cartons. The slidingly connected collection box 14 is used to receive the cartons after they are flipped over. The handles 15 on both sides of the box facilitate the operation of the operator. The four sets of support feet 16 symmetrically arranged at the bottom of the device body 1 provide stable support for the entire device and ensure stable operation.

[0029] The first motor 4 serves as the driving device for the conveyor belt 2. Its symmetrical arrangement ensures the balance of power transmission. The equally spaced arrangement of the push plates 3 ensures the continuous and stable pushing of the carton. The three sets of creases 7 and the equally spaced arrangement of the box studs 8 are all parameters designed according to the standard carton structure, ensuring the accuracy and reliability of the flipping action.

[0030] The working principle of a carton flipping device based on the embodiment is as follows: during the production process, the tail end of the carton is fixed by a carton nail 8, causing the carton nail 8 to protrude from the upper surface of the carton. If the carton is stacked directly, the bottom surface of the upper carton will be pressed, resulting in indentations or damage. This device uses an automated flipping operation to transfer the carton nail 8 from the stacking contact surface to the folding side, thereby eliminating the risk of stacking damage.

[0031] In the specific workflow, the operator places the flipped carton 6 horizontally on the conveyor belt 2, positioning it between two sets of push plates 3. The conveyor belt 2 is driven by the first motor 4, which moves the push plates 3 synchronously, pushing the flipped carton 6 towards the end. Figure 4 As shown, when the flipped carton 6 reaches the end of the conveyor belt 2, its tail contacts the baffle 5. Under continuous pushing action, the flipped carton 6 begins to bend along the preset crease 7. At this time, the auxiliary flipping mechanism is activated, and the second motor 10 drives the rotating shaft 11 to rotate at high speed, driving the annularly distributed rotating plates 12 to apply directional thrust to the surface of the carton, accelerating the carton to complete the flipping along the crease 7. Figure 6 As shown, during the flipping process, the carton changes from a flat unfolded state to a vertical folded structure, and the box nails 8 naturally move to the joints on both sides as the folding action is performed, completely detaching from the stacking contact area.

[0032] like Figure 7As shown, the flipped carton then enters the stacking stage. Under the guidance of the baffle 5, the flipped carton falls smoothly into the collection box 14. Since the carton nails 8 have been adjusted to the non-pressure-bearing position on the side, no local stress concentration will occur when multiple layers are stacked, effectively protecting the structural integrity of the carton. The entire process achieves fully automated operation of carton positioning, flipping and collection through the coordinated cooperation of the conveyor belt 2, the flipping mechanism and the stacking mechanism, which significantly improves production efficiency and avoids errors caused by manual intervention.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
