Description

Technical Field

[0001] This utility model relates to the field of wine packaging, and in particular to a packaging box pressing device. Background Technology

[0002] Baijiu (Chinese liquor) packaging boxes are generally multi-layered, such as a paper inner lining and an outer decorative layer. During the manufacturing process, each layer of material is first cut into the required planar shape, then the layers are glued together, folded to form a three-dimensional box, and a base plate is glued on. Finally, the box is pressed to ensure a stable connection at the joints and improve the box's strength. During the pressing process, molds are used to support the box and ensure its shape accuracy. Different shapes of packaging boxes require different molds. The most common baijiu packaging box is a regular rectangular box.

[0003] A search of Chinese Patent Publication No. CN219095394U reveals a pressing mold and pressing equipment for liquor packaging boxes. The pressing equipment includes a horizontal support platform with a detachable wooden mold mounted on it. The mold comprises a horizontal base plate and a vertical core. The core is formed by a top plate and four side plates, creating a cavity. The lower ends of the side plates are fixedly connected to the base plate. Support steps are provided on the outer sides of the bottom of each of the four side plates. A horizontal upper pressure plate is positioned above the mold and connected to a lifting mechanism. Four side pressure plates are arranged around the mold, each parallel to one of the side plates, and each side pressure plate is connected to a horizontal drive mechanism. The mold is entirely made of wood, making it lightweight and easy to move, install, and remove from the pressing equipment. Furthermore, due to the low hardness of wood, the packaging boxes are less likely to be damaged during the pressing process. Additionally, plywood can be used to prepare the mold, reducing costs.

[0004] To prevent mold growth inside the mold core, the aforementioned patent features multiple through holes on the side plate to ensure ventilation. However, each through hole needs to be sealed with tape before each use, which is cumbersome and affects work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a packaging box pressing device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6 As shown, a packaging box pressing device includes a support column 1, a workbench 2 fixedly connected to the top of the support column 1, a mold 3 set in the middle of the top of the workbench 2, the mold 3 including a housing 301 bolted to the top of the workbench 2, a support plate 302 welded to the outer wall of the housing 301, a plurality of first through holes 303 opened on both sides of the housing 301, the first through holes 303 being located above the support plate 302, and a plurality of second through holes 304 opened around the perimeter of the housing 301 being located below the support plate 302. The second through holes 304 do not need to be sealed and will not affect the pressing of the packaging box.

[0027] A side pressure mechanism 4 is provided around the mold 3. The side pressure mechanism 4 includes a rotary motor 401 bolted to the bottom of the workbench 2. The output end of the rotary motor 401 is connected to a lead screw 402 through a coupling. A mounting block 403 is threaded onto the lead screw 402. A slider 404 located around the housing 301 is slidably connected to the top of the workbench 2. A connecting rod 405 is hinged between the bottom of the slider 404 and the side wall of the mounting block 403. A side pressure plate 406 is fixedly connected to the side of the slider 404 near the housing 301. An elastic pad 407 is provided on the side pressure plate 406 to protect the packaging box and prevent the side pressure plate 406 from damaging the packaging box. The height of the side pressure plate 406 is equal to the height of the side wall of the packaging box, and the width of the side pressure plate 406 is equal to the width of the side wall of the packaging box.

[0028] The top of the mold 3 is provided with a pressing mechanism 5. The pressing mechanism 5 includes a mounting bracket 501 bolted to the rear side of the worktable 2. An electric push rod 502 is fixedly connected to the mounting bracket 501. An upper pressure plate 503 is fixedly connected to the bottom of the electric push rod 502. The length and width of the upper pressure plate 503 are equal to the length and width of the top wall of the packaging box, ensuring that the upper pressure plate 503 can fit against the top wall of the packaging box. At the same time, the side pressure plate 406 fits against the side wall of the packaging box to ensure the pressing effect, and the pressure plates do not interfere with each other.

[0029] An auxiliary mechanism 6 is provided inside the mold 3. The auxiliary mechanism 6 includes a parallel hydraulic cylinder 601 fixed to the top wall inside the housing 301. The two output ends of the parallel hydraulic cylinder 601 are fixedly connected to the mounting plate 602. Several plug rods 603 are fixedly connected to the side of the mounting plate 602 near the housing 301. The shape and size of the plug rods 603 are consistent with the first through hole 303. The mounting plate 602 is driven by the parallel hydraulic cylinder 601 to move the plug rods 603, thereby blocking the first through hole 303.

[0030] Working principle: In use, firstly, the parallel hydraulic cylinder 601 causes the mounting plate 602 to abut against the inner wall of the housing 301, so that the plug rod 603 completely seals the first through hole 303. The packaging box is then placed on the housing 301 with its opening facing down. The bottom of the packaging box is supported by the support plate 302. The rotary motor 401 is started, driving the lead screw 402 to rotate. The lead screw 402 drives the mounting block 403, causing one end of the connecting rod 405 to move downwards, thereby driving the other end of the connecting rod 405 to drive the slider 4. 04. The side pressure plates 406 are moved closer to each other to press the four sides of the packaging box. The upper pressure plate 503 is moved downward by the electric push rod 502 to press the top of the packaging box. After pressing, the side pressure plates 406 and the upper pressure plate 503 are reset. The mounting plate 602 is driven by the parallel hydraulic cylinder 601 to move the stopper rod 603 and pull the stopper rod 603 out of the first through hole 303, so that the air between the packaging box and the mold 3 is in a state of circulation, which makes it easier to remove the packaging box from the mold 3.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
