Description

Technical Field

[0001] The utility model relates to a bottom profile component of a packaging box, belonging to the technical field of packaging box production devices. Background Art

[0002] Automatic box forming technology is a common automated production technology in the box production field. Traditional manual labor is inefficient, with inaccurate measurement and the risk of packaging material loss. Automated packaging replaces manual labor and offers high precision. Furthermore, automated packaging lines improve product packaging consistency, reduce packaging errors, and thus increase production efficiency.

[0003] In the packaging box pressing process, the bottom needs to be folded and adhesive applied before pressing in the bottom forming stage. The existing pressing block design is generally symmetrical on both sides, which presses the folding areas on both sides of the bottom of the packaging box and solidifies the adhesive by cooling to achieve stable adhesion. However, for the bottom of the packaging box with folding areas or uneven shapes on both sides, the symmetrically set compacting device cannot meet the requirements of stable pressing, and it is easy to cause warping or bulging. In particular, the part in the middle that is not coated with adhesive is prone to glue leakage or warping, resulting in the product being less beautiful and inconvenient to transport. It is also easy to cause bulging during later use. Summary of the Invention

[0004] Purpose of the invention: In view of the deficiencies in the prior art, the present invention provides a bottom profile component for a packaging box to solve the problems mentioned in the above background technology.

[0005] Technical solution: A packaging box bottom pressing assembly includes a bottom pressing head and a sleeve box bottom. The bottom pressing head includes a cooling platform and a pressing boss arranged in the middle position above the cooling platform. The pressing boss is provided with a pressing nail assembly corresponding to the folded edge of the packaging box. The bottom of the sleeve box bottom is provided with a concave pressing groove that matches the shape of the pressing boss.

[0006] The pressing protrusion includes a first pressing platform and a second pressing platform that are arranged opposite to each other, a supporting shallow groove is provided between the first pressing platform and the second pressing platform, and a supporting nail row is provided near the middle position of the supporting shallow groove.

[0007] The utility model cooperates with the bottom pressing head and the bottom of the sleeve box. The bottom of the sleeve box is installed on the star axis, and the bottom of the sleeve box is supported on the inner side of the packaging box. The concave pressing groove of the sleeve box bottom cooperates with the pressing boss to press the bottom of the packaging box that has been coated with adhesive and temporarily bonded after preliminary folding, and the adhesive is quickly solidified by cooling to achieve stable bonding. The support nail row is used for supporting the edge of the folding area. Because the adhesive is generally applied in the fully covered area and the adhesive is not applied at the edge, it is necessary to set up a separate support nail row to support and fix the uncoated and squeezed area to avoid warping that affects the beauty of the packaging box and reduce the incidence of bulging during later transportation.

[0008] The press pin assembly includes thick area press pins arranged at the junction of the first press platform and the supporting shallow groove, and the second press platform and the supporting shallow groove. The thick area press pins are arranged in a triangular array along the direction of the first press platform in the folding area of the bottom of the packaging box on one side;

[0009] It also includes thin area pressing pins arranged at the edge of the second pressing platform, and the thin area pressing pins are correspondingly arranged at the folding area of the bottom of the packaging box on the other side.

[0010] According to the folding shape of the bottom of the packaging box, which is usually a triangle or other shape with a larger folding area or the folding areas on both sides overlap, when pressing the bottom folding area, thick area pressure pins arranged in a triangular array are set, and for the bottom of the packaging box that is thinner or has a smaller folding area on the other side, thin area pressure pins are set to perform compression, thereby improving the pressing effect of the bottom of the packaging box.

[0011] The supporting shallow groove is provided with first supporting convex surfaces distributed in a fan shape near the first pressing platform and the packaging box folding area, and the first supporting convex surfaces include at least two fan-shaped convex surfaces.

[0012] In order to prevent the profiling at the connection between the first press platform and the supporting shallow groove from producing a large drop, resulting in an obvious depression in part of the bottom, a first supporting convex surface is provided and a transition is achieved through a fan-shaped convex surface, making the final profiling effect more beautiful.

[0013] A second supporting surface is provided on both sides of the left and right edges of the supporting shallow groove close to the first press platform. The second supporting surface includes two parts, one part is provided in the supporting shallow groove, and the other part is provided adjacently on the side of the cooling platform.

[0014] In order to make the edge of the packaging box smoother, a second supporting surface is provided to support the edge of the packaging box. During the pressing process, this avoids depressions caused by a large difference between the pressing boss and the cooling table, which would result in an unsightly bottom of the packaging box.

[0015] Edge pressing pins are respectively provided on the side surface of the cooling table near the four corners of the pressing boss, and the edge pressing pins are directly facing the folding areas of the four corners of the packaging box.

[0016] In order to make the packaging box present a shape with a concave middle and four horizontal corners, edge pins are set at the corresponding four corners of the packaging box to ensure that the edges are firmly bonded. At the same time, the shape with a concave middle and four horizontal corners is more conducive to transportation and avoids expansion.

[0017] The first press platform and the second press platform are respectively provided with a detachable marking head which vertically passes through the cooling platform. The marking head is arranged close to the outer edge of the first press platform and the second press platform.

[0018] A detachable marking print head can be set up to realize free replacement of different marking print heads to meet product requirements.

[0019] A bent cooling channel is provided inside the cooling platform, and a water inlet and a water outlet of the cooling channel are both arranged on the side of the cooling platform.

[0020] By opening a cooling channel inside the cooling table, the cooling channel is connected to the coolant, which flows in the pipe and controls the temperature of the cooling table at a lower temperature. This can achieve rapid cooling, make the binder cool faster, increase the pressing efficiency, and further improve production efficiency.

[0021] Beneficial effect: The utility model cooperates with the bottom pressing head and the bottom of the sleeve box. The bottom of the sleeve box is installed on the star axis, and the bottom of the sleeve box is supported on the inside of the packaging box. The concave pressing groove of the sleeve box bottom cooperates with the pressing boss to press the bottom of the packaging box that has been coated with adhesive and temporarily bonded after preliminary folding, and the adhesive is quickly solidified by cooling to achieve stable bonding. The support nail row is used for support at the edge of the folding area. Because the adhesive is generally applied in the fully covered area and the adhesive is not applied at the edge, it is necessary to set up a separate support nail row to support and fix the uncoated and squeezed area to avoid warping that affects the beauty of the packaging box and reduce the incidence of bulging during later transportation.
