Description

[Technical field]

[0001] The utility model belongs to the technical field of product packaging, in particular to an automatic sealing device for a packaging box. [Background technology]

[0002] For example, for products such as coffee capsules or blocks, after the finished product is produced, a certain number of products of certain specifications need to be placed in a packaging box, and then the packaging box is sealed to obtain the boxed product. The traditional way is to manually take the products on the assembly line for packaging, and each packaging box needs to be folded one by one from the flat box paper, and then sealed after packaging, which is inefficient, prone to errors, and the packaging quality is also inconsistent.

[0003] In order to improve the production efficiency of boxed products, there are now related automated packaging production lines designed to automatically fold boxes, automatically grab products into packaging boxes, and automatically seal to obtain boxed products. For example, China Patent Publication No. CN113022953A discloses an automatic boxing and packaging equipment for block products, which can realize automatic boxing and packaging of block products, wherein the packaging box forming device includes a box paper tray mechanism, a box paper suction cup mechanism, an upper forming conveyor belt, a first glue spraying machine, a forming pressing mechanism, a lower forming conveyor belt, a product boxing mechanism, a second glue spraying mechanism, and a packaging box sealing mechanism. The packaging box sealing mechanism includes a cover plate pushing mechanism and a side plate turning mechanism arranged on one side of the cover plate pushing mechanism. The cover plate pushing mechanism is used to flatten the vertical upper cover, and the plate turning mechanism is used to turn the left and right side plates of the upper cover downward and bond them to the corresponding side plates through the previous glue spraying, so as to realize the sealing of the packaging box to obtain boxed products. However, the above scheme still has the following two problems:

[0004] (1) The design of the packaging box capping mechanism is relatively complex. The plate pushing mechanism and the side plate flipping mechanism have three driving modules. The plate pushing mechanism is provided with a pushing plate translation component and a pushing plate lifting component, which drive the pushing plate to translate and press down at the same time to flatten the vertical upper cover; the side plate flipping mechanism is provided with a flipping driving cylinder to drive the flipping plate to flip the left and right side plates of the upper cover downward. Only one packaging box can be automatically capped at a time. The driving method is complicated and the packaging efficiency is low.

[0005] (2) The push plate for pushing the upper cover and the flip pressure plate for flipping the side plate are both in direct rigid contact with the packaging box, which can easily damage or scratch the packaging box, thereby affecting the quality of the packaging and increasing the cost of the packaging.

[0006] Therefore, it is necessary to provide an automatic sealing device for a packaging box to solve the above technical problems. [Contents of the utility model]

[0042] The upper push plate 124 is fixed to the lower part of the support frame 122 by screws 123, and the rear contact plate 125, the left push plate 1263, the right push plate 1273 and the front push plate 1283 surround and form the installation cavity 13, and the upper push plate 124 is horizontally arranged inside the installation cavity 13. The upper push plate 124, the rear contact plate 125, the left push plate 1263, the right push plate 1273 and the front push plate 1283 are all planar structures and together surround and form a accommodating cavity 14 that is contoured to the packaging box 200.

[0043] Since the packaging box has a rectangular or cube structure, the front and rear dimensions of the packaging box are the same, and the left and right dimensions are the same as the right dimensions. Therefore, the left push plate 1263 and the right push plate 1273 have the same structure, and the rear contact plate 125 and the front push plate 1283 have the same structure.

[0044] The rear contact plate 125 is in a vertical state, and the upper push plate 124 is in a horizontal state; before packaging, the left push plate 1263, the right push plate 1273 and the front push plate 1283 are all at an angle to the vertical plane. When packaging is completed, the left push plate 1263, the right push plate 1273 and the front push plate 1283 are all in a vertical state and respectively make the left cover 208 contact with the left side 204 of the bottom box, the right cover 209 with the right side 205 of the bottom box, and the front cover 207 with the front side 203 of the bottom box to achieve bonding, thereby completing the sealing action of the packaging box 200. When the sealing is completed, the packaging box 200 is just accommodated in the accommodating cavity 14.

[0045] When the covering module 12 moves along the YZ direction and contacts the packaging box for covering, in order to prevent the pushing plate of the covering module 12 from damaging or scratching the packaging box 200, an arc-shaped curling edge 15 curled outward and extending upward is provided at the lower end of the rear contact plate 125, the left pushing plate 1263, the right pushing plate 1273 and the front pushing plate 1283. When the arc-shaped curling edge 15 contacts the surface of the packaging box 200, it is not easy to damage or scratch the packaging box 200.

[0046] The manipulator 3 is a two-axis spider manipulator, which includes a fixed plate 31, two drive motors 32 installed on the fixed plate 31, a rotating arm 33 driven by the drive motor 32 to rotate, a mounting frame 34 fixed above the mounting plate 2, and a connecting rod 35 whose upper end is connected to the rotating arm 33 and whose lower end is installed on the mounting frame 34.

[0047] When the automatic packaging box capping device 100 provided by the present invention is applied, after the glue sprayer (not shown in the figure) sprays glue on the front cover 207, the left cover 208 and the right cover 209 of the upper cover part 202 of the packaging box 200, the conveyor line (not shown in the figure) conveys the packaging box 200 to the bottom of the automatic packaging box capping device 100 along the X direction. The three packaging boxes 200 are located below the three capping modules 12, and each packaging box 200 corresponds to each capping module 12 one by one. The manipulator 3 drives the mounting plate 2 to drive the capping mechanism 1 to move along the YZ direction, so that the front pushing component 128 of each capping module 12 moves to the back of the upper cover 206. The manipulator 3 drives the mounting plate 2 to drive the capping mechanism 1 to move along the YZ direction, so that the front pushing component 128 moves forward and downward at the same time to make the upper cover part 202 flip forward and downward. When the rear contact plate 125 contacts the rear side 210 of the bottom box, the manipulator 3 stops driving the mounting plate 2 to drive the capping mechanism 1 to move in the Y direction, the manipulator 3 drives the mounting plate 2 to drive the capping mechanism 1 to move downward, and at the same time, the upper pushing plate 124 moves downward to flatten the upper cover 206 of the upper cover part 202. After the upper cover 206 is completely flattened, the manipulator 3 stops driving the capping mechanism 1 to move downward, and the first cylinder 1267, the second cylinder 1277 and the third cylinder 1287 respectively drive the first push rod 1266, the second push rod 1276 and the third push rod 1286 to move downward at the same time, so that the rear contact plate 125, the left pushing plate 1263, the right pushing plate 1273 and the front pushing plate 1283 are all in a vertical state and form a clamp around the packaging box 200, and respectively make the left cover 208 contact with the left side 204 of the bottom box, the right cover 209 with the right side 205 of the bottom box, and the front cover 207 with the front side 203 of the bottom box to achieve bonding, thereby completing the capping action of the packaging box 200.

[0048] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
