Description

Technical Field

[0001] The utility model relates to the technical field of packaging material production, in particular to an automatic folding and forming device for an octagonal box cover. Background Art

[0002] Octagonal boxes are made from a special high-strength, reinforced corrugated cardboard. They can be designed to fit container dimensions, optimizing logistics space, increasing shipping capacity, and reducing freight costs. The production process for the box lid involves first cutting the cardboard into shape using a die-cutter, then folding the cut cardboard into the lid. Currently, box lids are primarily folded manually. Due to their large size, these processes typically require two or more workers, and folding a single box takes 3-5 minutes. This labor-intensive and inefficient process limits production capacity, necessitating the design of a device that can automatically fold the lid to address these challenges. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0023] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0024] like Figure 1-2 As shown, the automatic folding and forming device for the octagonal box cover in this embodiment includes a frame 1, an octagonal mold 2, a first drive unit 3, a down-pressing assembly, a second drive unit 4, a side pressure plate 5 and an ejection assembly. The octagonal mold 2 is arranged on the frame 1 for placing the cardboard to be formed. The first drive unit 3 is arranged above the octagonal mold 2 through a bracket 6. The down-pressing assembly is connected to the first drive unit 3, and the down-pressing assembly can be driven to move up and down by the first drive unit 3. The second drive unit 4 is arranged around the octagonal mold 2 in a rectangular symmetrical manner. The side pressure plate 5 is connected to the second drive unit 4, and the side pressure plate 5 can be driven to move forward and backward relative to the side of the octagonal mold 2 by the second drive unit 4.

[0025] Combine Figure 3-4 As shown, the pressing assembly includes a connecting plate 7, a connecting arm 8 and a pressing plate 9. Eight connecting arms 8 are evenly spaced around the periphery of the connecting plate 7. The end of each connecting arm 8 is provided with a pressing plate 9 arranged longitudinally. The lengths of the pressing plates 9 are different. The length of the pressing plates 9 corresponding to the oblique sides of the octagonal mold 2 is greater than the length of the pressing plates 9 corresponding to the straight sides of the octagonal mold 2. The purpose of this design is to ensure that the glued part of the cardboard is pressed down first and the un-glued part is pressed down later, so that the two adjacent sides of the cardboard are bonded together.

[0026] The bottom end of the lower pressing plate 9 is provided with an arc-shaped corner 10, which can prevent the edge of the lower pressing plate 9 from causing damage to the cardboard during the pressing process.

[0027] Combine Figure 5 As shown, the ejection assembly includes a third drive unit 11 and an ejection plate 12. The third drive unit 11 is arranged on the frame 1, and the ejection plate 12 is connected to the third drive unit 11. The octagonal mold 2 is provided with an ejection groove 13 that matches the shape of the ejection plate 12. The third drive unit 11 can drive the ejection plate 12 to move up and down along the ejection groove 13. Among them, the ejection plate 12 and the ejection groove 13 are both cross-shaped structures. Of course, other shapes that are conducive to increasing the contact area between the ejection plate 12 and the cardboard can also be used.

[0028] The first drive unit 3 , the second drive unit 4 and the third drive unit 11 may all adopt linear drive methods commonly used in the art, such as a pneumatic cylinder, a hydraulic cylinder, an electric push rod, a linear motor and the like.

[0029] The shape of the cardboard to be formed is as follows Figure 6 As shown in the figure, the dotted line part represents the crease line, the dotted line part represents the break line, and the shaded part represents the glue-coated surface.

[0030] When folding, glue is first applied to the glued surface, and then the cardboard is placed in the center of the top surface of the octagonal mold 2. First, the first drive unit 3 drives the downward pressure assembly to move downward, folding the eight outer rectangular sides of the cardboard downward, ensuring that the short sides and glued surface of the cardboard are folded before the long sides. This allows the two sides of the long side to press against the glued surfaces on both sides of the short side, achieving bonding between the two adjacent sides.

[0031] Then the second driving unit 4 drives the side pressure plate 5 to move toward the side of the octagonal mold 2 so that the side pressure plate 5 is pressed on the bonding part and kept for a period of time, thereby making the cardboard bonding more firmly.

[0032] Then the first drive unit 3 and the second drive unit 4 are reset respectively, and the third drive unit 11 drives the ejection plate 12 to move upward, ejecting the folded carton from the octagonal mold 2. Finally, the staff removes the carton and puts in new cardboard.

[0033] Compared with the traditional manual folding method, the utility model effectively improves the production efficiency. It only takes dozens of seconds to fold a carton, and saves a lot of labor, thereby reducing the production cost of the enterprise.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, the technical solutions of the various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
